The invention discloses a safety protection mechanism for a building construction elevator. The safety protection mechanism comprises a protection foundation pit, an elevator protection housing and anelevator body. The elevator protection housing is vertically arranged on the inner wall of the protection foundation pit. The elevator body is located in the elevator protection housing. The inner wall of the elevator protection housing is fixedly connected with a vertically-arranged fixed friction strip. The outer wall of the elevator body is fixedly connected with friction plates symmetricallyabout the fixed friction strip. The position, corresponding to one friction plate, of the inner top of the elevator body is fixedly connected with a piston barrel and a slide rheostat. The safety protection mechanism has the advantages that the safety protection mechanism is additionally mounted for the building construction elevator, once the elevator body falls due to equipment or human factor problems, heat is generated through contact between the fixed friction strip and the friction plates to reduce the falling speed of the elevator body, a memory metal rod is in contact with an electricconduction ring, a circuit is forced to ascend at the communicating position, the situation of equipment damage and casualties caused by the too high falling speed is avoided, and high safety is achieved.

The invention discloses a composite airtight method for a roadway under hard roof caving impact in a goaf. The composite airtight method comprises the steps that a buffer chamber is obliquely excavated to the two sides of the roadway near two roadway stopping lines; a triangular concrete airtight wall is arranged at the position close to the edge of the buffer chamber; three layers of steel wire meshes with sprayed concrete are evenly laid behind the airtight wall in equal distances; and a layer of common concrete airtight wall is arranged behind the steel wire meshes. According to the composite airtight method, in the goaf with a hard roof, huge impact waves generated by caving of the hard roof enter the roadway and are weakened by the triangular concrete airtight wall and the buffer chamber at first, then the rest impact waves are subjected to the flexible impact weakening and absorbing effect of the three layers of steel wire meshes containing the concrete, and at last the remainingpart of impact force is resisted by the common concrete airtight wall. A positive effect is achieved on the roadway and the safety of personnel, and the conditions of equipment shutdown and casualties are avoided.

The invention relates to the technical field of building construction tools, and discloses an all-steel intelligent building construction lifting platform, which includes steel columns symmetrically distributed left and right, lifting cars, bearing platforms and lifting motors, and the opposite sides of the two steel columns are Hollow boards are fixed, chutes are provided on the opposite sides of the two hollow boards, and a plurality of through holes are equally spaced on the front and rear surfaces of the two hollow boards; Personnel can turn on the first air pump and the second air pump through the switch inside the elevator car, and the first air pump will inflate the first air bag, so that the first air bag will be propped up and a descending channel will be formed, while the second air pump will inflate the second air bag Inflate the second air bag to prop up the second air bag and push away the flat plate covered on the base, then the construction workers trapped in the lift car remove the cover plate in the hole and enter the first propped up air bag through the hole. The self-rescue can be completed by sliding the first air bag onto the second air bag.

The invention discloses an auxiliary device for replacing an anti-falling safety device of a construction elevator, which relates to the technical field of building construction and includes a base, the upper end of which is fixedly connected with a lifting rod, and a sliding groove is provided on the side wall of the lifting rod. A lifting block is slidably connected in the sliding groove, a sliding plate is fixedly connected to the side wall of the lifting block, a hanging cage is fixedly connected to the lower end of the sliding plate, a lifting mechanism is fixedly connected to the side wall of the lifting rod, and the lifting mechanism is fixedly connected to the side wall of the lifting rod. The side wall of the rod is fixedly connected with the first fixed pulley. When the cage of the elevator fails and falls, the falling speed will show an acceleration trend. The speed detection is realized through the acceleration sensor. After the detection is successful, the The signal is transmitted to the control panel unit, and through the cooperative use of the control panel unit and the limit mechanism, the limit effect on the sliding block is lost, so that the positioning mechanism realizes the positioning of the elevator.

The invention discloses a high-voltage cable plug joint fixing device and a method for using the same. There is a socket, and the number of sliding shells is set to four, which are distributed in a matrix in the shell. The section of the power socket with the plug interface is arranged between the sliding shells at the top, and the section of the plug with the plug connector is set at the sliding shell at the bottom. Between the shells, the slots are set on both sides of the power socket and the plug, the push plate is slidably set in the sliding shell, one side of which is fixed with a plug matching the slot, and the top sleeve is fixed on the power socket and the plug. The outer periphery of the plug is used to push the upper and lower sliding shells to move toward each other. One end of the connecting rod is hinged on the side of the push plate away from the insert block, and the other end is hinged on the inner wall of the housing. When the upper and lower sliding shells move toward each other, the connecting rod acts to push The plate drives the insert block to be inserted into the slot to fix the power socket and the plug, and now the power socket is connected with the plug.

The invention discloses a rail transit vehicle, a method and a system for controlling the door of the rail transit vehicle. The rail transit vehicle includes a plurality of compartments, and each compartment includes a plurality of doors separately arranged on both sides of the compartment; each of the doors is correspondingly equipped with A door controller for receiving the door control signal and controlling the opening or closing of the door; the door control signal includes a door opening command, a door closing command, a zero speed signal, a door enabling signal, and a platform enabling signal; when the door opening command , the zero speed signal, the door enable signal, and the platform enable signal are all valid, the door controller controls the corresponding door to open. The invention can ensure that only the doors facing the platform side and within the platform range can be opened, avoiding casualties caused by passengers or staff getting off from the doors outside the platform, ensuring the safety of passengers or staff, and improving vehicle safety; The invention has the advantages of being safe, reliable, easy to realize, and convenient to popularize and apply.

The invention discloses an underground garage for reasonably controlling parking space allocation and parking space occupied spaces. The underground garage comprises a main building basement and an external underground garage area located on the outer side of the main building basement, the external underground garage area is provided with a first traffic lane area, a second traffic lane area, a miniature vehicle parking area, a medium-sized vehicle parking area and a large vehicle parking area, and the medium-sized vehicle parking area and the large vehicle parking area are arranged between the first traffic lane area and the second traffic lane area; the main building basement is provided with an upper layer space and a lower layer space, the upper layer space is provided with a storeroom, the lower layer space is provided with a main parking area or an equipment area, the joint position of the main building basement and the external underground garage area is provided with a self-walking parking area, and parking space dynamically allocating and computing systems are arranged on the external underground garage area and the lower layer space. According to the underground garage, the underground garage is reasonably partitioned, the area occupied by vehicles is reduced, the size of garage column grids is effectively controlled, and the problem that an existing three-dimensional garage cannot achieve dynamic distribution of unoccupied parking spaces is solved.
