The invention relates to a mine belt protective system along-line shutting query method. The mine belt protective system along-line shutting query method comprises a query host, a plurality of along-line shutting modules and a terminal module. The query method includes the steps that the query host sends a query signal, the along-line shutting modules and the terminal module process the query signal and replies the query signal, and the query host then processes the replied signal to achieve remote fault location, remote input and remote control. The mine belt protective system along-line shutting query method has the beneficial effects that remote fault location and along-line shutting can be achieved without address coding for along-line shutting, and replacement without influencing positioning positions can be achieved; and the structure is simple, operation is convenient, normal communication can be carried out by sequentially connecting equipment with cables, debugging and allocation are not needed, installation debugging and allocation are greatly simplified, the fault rate is reduced, and the working efficiency is improved.

The invention discloses auxiliary welding equipment for a box type steel component and a machining process of the auxiliary welding equipment, and relates to the technical field of steel structure machining. The auxiliary welding equipment for the box type steel component comprises a jig frame and further comprises a main body positioning device, a welding supporting device and a control system; the main body positioning device is used for fixing and positioning a bottom plate and a top plate; the welding supporting device is used for temporarily fixing and positioning partition plates and side plates; and the control system is a programmable logic controller and is electrically connected with the positioning device and the welding supporting device. In the auxiliary welding equipment, the design positions of all parts of the box-type steel component are programmed in the control system, then the main body positioning device and the welding supporting device are controlled to work through the control system, and all the parts of the box-type steel component are positioned, so that the position accuracy of all the parts of the box-type steel component is improved, and the product quality of the box type steel component is ensured; and the processing efficiency is greatly improved.

The invention provides a two-way floating force-increasing clamping mechanism for high-pressure sealing. The mechanism comprises a base, a large air cylinder located below the base, a push-pull blockconnected with the upper end of a piston rod of the large air cylinder, a positioning tooling arranged in the middle of the upper end of the base as well as a left slider press head and a right sliderpress head which are directly opposite to each other and arranged on the base in a sliding manner, a left sealing gasket and a right sealing gasket are arranged on the left side and the right side, located in the workpiece positions of the positioning tooling, of the left slider press head and the right slider press head respectively, the push-pull block is arranged in a sliding groove formed inthe lower part of the base, a left connecting rod and a right connecting rod are hinged to the middle of the push-pull block through central drive pins, the left connecting rod is hinged with the leftslider press head through a left drive pin, and the right connecting rod is hinged with the right slider press head through a right drive pin. The mechanism is compact in structure and occupies smallspace; by adoption of the force-increasing principle, a relatively large blocking force requirement of ports of a to-be-detected workpiece can be met by one air cylinder; and clamping force of the ports on two sides of the to-be-detected workpiece can be balanced adaptively, and the positioning of the workpiece cannot be affected by the clamping force.

The invention discloses an antistatic three-layer scratch resistant protective pasting film. With a three-layer structure, the protective film includes a protective layer, a use layer and a release layer that are stacked together in order. The use layer includes a first optical PET film, a hardened coating and a first organosilicon pressure-sensitive adhesive. The first organosilicon pressure-sensitive adhesive contains 50-200nm nanoscale silver particles. According to the invention, the antistatic three-layer scratch resistant protective pasting film can be applied in protective pasting films of mobile phones. The adding of nano-silver particles into the organosilicon pressure-sensitive adhesive in the use layer ensures high transparency of the protective pasting film (greater than 90%). Meanwhile, with an antistatic function, the protective pasting film cannot absorb dust or occur self-adsorption and affect positioning during pasting, and cannot generate touch screen failure after pasting, thus being able to improve the pasting yield rate of terminal users.

The device comprises an oscillation mixing device, wherein the oscillation mixing device comprises an oscillation tube for placing a mixing tube, and the inner wall of the oscillation tube is matched with the outer wall of the mixing tube. The device is characterized inthat a flexible tissue connected with an external bracket is arranged at the upper part of the oscillation tube; one or more vibration mechanism is arranged at the bottom of the inner cavity of the oscillation tube. The device can be used for quickly and effectively realizing uniform distribution of suspensions, such as a sample or reaction reagent, for a long time, and has the advantages of simple structure, low cost, good uniform mixing effect, no occurrence of pollution carrying, low failure rate and the like.

The invention discloses a composite structure of a radiator fan and a molding method thereof. The composite structure of the radiator fan is characterized by comprising a base plate, a stator insertion seat positioning part, a stator group, a plastic combined seat part, an axle center and a rotor blade group, wherein the base plate comprises an attached surface and a stator assembly surface; the stator insertion seat positioning part is arranged in the center of the stator assembly surface; the stator group comprises silicon steel sheets, coils and a plastic insulating frame seat; the plasticcombined seat part is integrally formed on the stator group, and can be inserted, connected and matched with the stator insertion seat positioning part; the axle center is connected to the plastic combined seat part, and has a root fixedly connected to the center of the plastic combined seat part; and the rotor blade group comprises a hub, blades, a shaft sleeve, a bearing component and magnetic rings. The axle center is integrally assembled on the plastic structure of the stator group, and a composite design is adopted between the stator group and the base plate, so precise positioning between the axle shaft and the silicon steel sheets and coils of the stator group can be easily realized by the planning design of an extrusion mould. Therefore, the composite structure of the radiator fancan achieve great improvements in combination and position correction accuracy, is smoother to run and has the advantages of effectively reducing noises, along with practicability and progressiveness.
