Description
Technical Field
The invention relates to an improvement technology of a related support structure of an elevator car, in particular to an elevator car bottom structure with balanced support.
Background
The elevator is a special device which is used in a building and mainly provides a lifting function, the elevator runs through a traction system arranged at the top to drive an elevator car and a counterweight to move up and down relatively, so that the transportation of a load on the elevation of the car is realized, the up-and-down movement of the car is tied on the stroke of a traction rope in the running process of the car, the traction rope penetrates through the car, the length of the traction rope around the car determines the up-and-down movement of the car, in order to ensure the stable running of the car, the traction rope penetrates through the car, the distance of the traction rope is changed in the running process, and the traction car moves, the traction rope needs to penetrate through a guide wheel, the guide wheel is positioned at a fixed position of the car and is convenient to penetrate through the traction rope, and one guide wheel is fixed at the bottom of the car and is usually fixed on a car bottom structure. The car bottom also plays a role in supporting the car, the interior of the car is flat ground, the load in the car is uncertain, the weight is heavier at any position on the car ground, generally, more supporting and fixing structures are needed for leveling the weight, so the car bottom structure has larger volume and more structures, the guide wheels are also needed to be connected with the car bottom structure, and a clearance needs to be reserved for the traction ropes to pass through, therefore, the car bottom structure is complex and cannot be suitable for the elevator with small load, the elevator with small load needs to have a light car bottom structure, and the balance of the load support of the elevator can be ensured.
Disclosure of Invention
The invention aims to overcome the defects in the prior art and provide a balanced supporting elevator car bottom structure.
The technical scheme adopted by the invention for solving the problems is as follows: the elevator car bottom beam is connected with the guide wheels, the guide wheels are arranged in the length direction of the elevator car bottom beam in two or more ways, the horizontal positions between the guide wheels are the same in height and are mutually parallel in the axial direction, the traction ropes sequentially penetrate through the guide wheels, the upper portion of the elevator car bottom beam is fixedly provided with a balance support structure, the balance support structure comprises a limiting frame for fixing the edge of the bottom of the elevator car, and the limiting frame extends along the front-back direction of the elevator car.
The holistic thickness of sedan-chair bottom structure of this device is little, and in order to practice thrift the thickness at the bottom of the sedan-chair, most leading wheel diameter distance overlaps the setting with the side of sedan-chair floorbar, only reserves the edge that needs work and lies in the sedan-chair bottom structure outside, the thickness of structure at the bottom of the sedan-chair that has significantly reduced.
The device is a fixing structure used for the bottom of the elevator car, plays a role in supporting the car and protecting the car, achieves the effect of surface support by arranging a balance support structure, improves the overall supporting effect of the elevator, and has a good promoting effect on the load balance of the elevator.
