An auxiliary device for replacement of a construction hoist anti-fall safety device

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to an auxiliary device for replacement of a construction elevator anti-fall safety device. Background technique [0002] Construction elevators are construction elevators for buildings, also known as outdoor elevators. Construction elevators are construction machines that use cages to transport workers or objects up and down along the guide rails. They are mainly used for interior and exterior decoration of high-rise buildings. The vertical transportation equipment has a high frequency of use. The anti-fall safety device is an important part of the construction elevator. When the cage of the elevator fails and falls, and the falling speed reaches the action speed of the anti-fall safety device, the anti-fall safety device will automatically open. For the braking part, the cage is stopped on the guide rail frame, which greatly improves the safety factor of the elevator....

[0002] Construction elevators are construction elevators for buildings, also known as outdoor elevators. Construction elevators are construction machines that use cages to transport workers or objects up and down along the guide rails. They are mainly used for interior and exterior decoration of high-rise buildings. The vertical transportation equipment has a high frequency of use. The anti-fall safety device is an important part of the construction elevator. When the cage of the elevator fails and falls, and the falling speed reaches the action speed of the anti-fall safety device, the anti-fall safety device will automatically open. For the braking part, the cage is stopped on the guide rail frame, which greatly improves the safety factor of the elevator. Due to some precise braking safety devices, damage is prone to occur during the braking process, and the damaged safety device part needs to be repaired in time. Replacement installation avoids unnecessary dangerous situations. The traditional safety device is welded in one piece, and the disassembly process is difficult to carry out. After the disassembly is completed, a new safety device will be replaced. For some undamaged devices, it will be damaged together with The components are disassembled and replaced together, so that the loss of replacement is relatively large. For this reason, we propose a replacement auxiliary device for the safety device of construction elevators to solve the above problems.
