technical background

With the centralization and large-scale development of mine production, mine elevators are used as a transportation tool for lifting personnel and materials between multiple levels in mine shafts (blind shafts), and their lifting efficiency has been significantly improved, but they have higher requirements for safety and reliability. At present, most elevators use rigid guide rails with a small gap with the car, so there will be no problems with the swing of the car during loading and the lateral movement of the car before the elevator runs. But for the flexible guide rail elevator, the car will have a large swing during loading and unloading. The existing mining hoist system uses the cradle, tank supporting machine and tank seat in the receiving device to solve the problem of receiving and stability, but these structures are mainly for heavy-duty cages, and for light-load The flexible guide rail mine elevator is not applicable. Therefore need a kind of device to solve this problem, and at present, still do not have a kind of mechanism to solve this class problem.

Beneficial effects: due to the adoption of the above-mentioned technical scheme, the utility model can solve the problem of car stop swing, safety protection and smooth operation of the elevator. It solves the car swing problem when people or objects enter and exit the flexible guide mine elevator, avoids various safety problems caused by the deflection when the car runs again, makes the car start stably after stopping at the floor, and improves the elevator safety. Reliability and stability, has the following advantages:

(1) The stabilizing device is powered by the car door, which ensures the synchronization between the stabilizing device and the opening and closing of the door.

(2) The self-locking problem of the stabilizing device is solved, and the self-locking of the stabilizing device that requires a large torque is overcome.

(3) The stabilizer bar is symmetrically inserted into the hoistway wall bracket, and the energy of the car's swing and shaking is finally converted into the internal energy of the hoistway wall.

(4) The structure is simple, easy to install and maintain, and the cost is low.
