Description

A flexible guiding special elevator car stabilization device and method

technical field

The device relates to a flexible-guided special elevator car stabilization device and method, and is especially suitable for solving the floor-stop swing of a mining elevator car with flexible guide rails, and is also suitable for solving the swing problem of other flexible-guided lifting equipment.

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.

The lower part of the connecting plate has a straight slot; the stabilizer bar is arranged in the slide rail of the stabilizer bracket, and the lower part of the stabilizer bar is provided with four bearings, and the bearings are fixed on the stabilizer bar through the bearing shaft; the rocker bar There is a straight notch in the middle.

Use the method for stabilizing the flexible guiding special elevator car of said device, comprising the steps:

a. When the elevator stops at the floor, the door operator drives the two elevator car door panels to move to both sides respectively, and at the same time drives the connecting plate to move to both sides. When it moves downward, the driven pin hinged with the active pin also moves downward. The top section of the driven pin breaks away from the bottom surface of the stabilizer bar, and the friction self-locking is released. When the displacement of the connecting plate reaches the straight notch at the lower part of the connecting plate When the width is wide, the connecting plate drives the stabilizer bar to move to both sides. When it reaches the specified position, the bearing breaks away from the bow, and the return spring drives the driven pin to move upward through the rocker. When it moves to the set stop position, it hinders the stabilizer bar. Move in the opposite direction to form self-locking. At this time, the car is fixed at the landing position, and the kinetic energy of the load and the momentum of the car are finally consumed on the hoistway wall;

b. After the loading and unloading is completed, the car door is closed, and the two elevator car door panels drive the bumper to slide in the stabilizer bar chute through the connecting plate, and hit the driving bearing to make the driving pin and the driven pin move downward. During this process, The self-locking is opened, the connecting plate finishes sliding, and the stabilizer bar is driven to move inward along the slide rail of the stabilizer bracket until the set position, the bearing breaks away from the bow, the driven pin moves upward along the vertical track, and finally withstands the bottom surface of the stabilizer bar , forming self-locking, at this time the elevator car door panel is completely closed, all structures return to the initial position, and the elevator can run.

Beneficial effects: due to the adoption of the above-mentioned technical solution, the present invention can solve the problems 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.
