Technical Field
[0001] The utility model relates to the technical field of elevator car bottoms, in particular to a high-applicability and low-cost elevator car bottom. Background Art
[0002] An elevator is a permanent transportation device that serves several specific floors in a building and whose car runs on at least two rows of rigid tracks that are perpendicular to the horizontal plane or inclined at an angle of less than 15° to the plumb line. Modern elevators are mainly composed of traction machines (winch), guide rails, counterweight devices, safety devices (such as speed limiters, safety clamps and buffers, etc.), signal control systems, cars and hall doors, etc. These parts are installed in the shaft and machine room of the building respectively. Usually, wire rope friction transmission is adopted. The wire rope is passed around the traction wheel, and the two ends are connected to the car and the counterweight respectively. The motor drives the traction wheel to make the car rise and fall.
[0003] The existing low-cost elevator car bottom usually has insufficient cushioning effect when in use. When landing, the impact force with the bottom of the elevator shaft is relatively large. Due to the low cost of the car bottom, it is very likely to be damaged. In addition, the structural strength of the low-cost car bottom may be insufficient and cannot bear a large mass. In order to solve the shortcomings of the existing technology, we propose a highly applicable low-cost elevator car bottom. Utility Model Content

[0012] Beneficial Effects
[0013] Compared with the prior art, the utility model has the following beneficial effects:
[0014] 1. In the utility model, by providing the top sliding rail, the top sliding block, the top buffer cylinder, the rotating rod, the bottom sliding block, the bottom sliding rail and the bottom buffer cylinder, the device can provide a certain degree of buffering effect for the car bottom, so that when the elevator car bottom falls to the bottom of the elevator shaft, the bottom of the elevator car will not be damaged due to collision, and the elevator can fall to the bottom of the elevator shaft more smoothly, and the bottom of the car can be better protected. When the car falls to the bottom of the elevator shaft, the bottom sliding rail contacts the ground, and the car compresses the two sets of rotating rods to rotate, and at the same time pushes the top sliding block and the bottom sliding block to slide in the middle of the top sliding rail and the bottom sliding rail respectively, compressing the top buffer cylinder and the bottom buffer cylinder. The compression of the top buffer cylinder and the bottom buffer cylinder can absorb part of the kinetic energy when the elevator falls, provide buffering effect for the car, and better protect the bottom of the car.
[0015] 2. In the utility model, by setting I-beams and hollow steel pipes, the device can ensure the strength of the bottom of the elevator car as much as possible at a low cost, so that the bottom of the elevator car can support heavier and higher-quality objects, and reduce the possibility of damage to the elevator car bottom when it lands. The three groups of I-beams inside the car bottom frame are used as main beams, and the six groups of hollow steel pipes are horizontally arranged between the side walls of the I-beams as secondary beams, which not only ensures the strength of the structure, but also prevents the weight of the car bottom from being too heavy.
