Description

Elevator car platform structure with balanced support

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.

Furthermore, the car bottom beam is arranged along the acting direction of the door, the cross section of the car bottom beam is in a shape of the Chinese character 'ji', the upper edge of the car bottom beam is transversely outwards folded to form a top edge, the upper part of the top edge is fixedly connected with a limiting frame, the limiting frame is also transversely arranged and is vertical to the extending direction of the car bottom beam, and the car bottom beam and the limiting frame form a surface type supporting structure and jointly support the car. The car platform beam is of a long straight strip structure, the opposite supporting effect of the car platform beam is insufficient, the bottom surface of the car platform cannot be completely supported, and the car platform beam is matched with the limiting frame to provide support from the other direction to form a complete plane supporting structure.

The wheel carrier and the sedan-chair floorbar separate arrangement reserve safe structure of keeping away for the operation of leading wheel, simultaneously, have reduced the degree of difficulty of girder processing, because the thickness of the material of girder is high, the number of times of buckling is many, and the number of times of upset is also good, and the tensile change of material is big to cause the precision reduction of structure, and the number of times of buckling of the single piece of this structure is few, the processing degree of difficulty greatly reduced, and the precision improves, so has improved economic benefits.

Furthermore, spacing is rectangular shape structure, has the constant head tank at its upper surface shaping, and spacing is including two relative settings to connect respectively and fix the both ends at the sedan-chair floorbar, the interval is fixed with a plurality of snubber blocks on the constant head tank, and the upper surface of snubber block is fixed with the bottom of car. The effect of snubber block is the vibrations that reduce the car, improves the travelling comfort, and the snubber block equipartition sets up, shares the weight of structure.

Furthermore, the car bottom beam is provided with a wheel carrier in parallel, the wheel carrier is formed with a side vertical plate, the top of the side vertical plate is transversely formed with a top edge strip, the top edge strip is arranged opposite to the top edge of the top of the car bottom beam and is positioned at the same height, a long strip-shaped rope passing groove is formed between the car bottom beam and the wheel carrier, two or more than two guide wheels are arranged in the rope passing groove, the rotation direction of the guide wheels is the same as the length direction of the rope passing groove, the dragging ropes parallelly pass through the rope passing groove and pass through the guide wheels, and two ends of a wheel shaft connected with the guide wheels are respectively fixed on the car bottom beam and the wheel carrier.

Furthermore, cross and transversely be connected with the space support frame between the grooving, the distance of space support frame is the same with the width of crossing the grooving, and the both ends of space support frame are the shaping respectively has the connector, and the connector welding is on sedan-chair floorbar and wheel carrier, perhaps wears to establish on the stationary plane that corresponds through screw, rivet. The space between the rope passing grooves is used for the guide wheels to rotate freely, in order to improve the structural strength, a space supporting frame is arranged, and the car platform fixing piece is of a rigid structure and used for keeping a corresponding space distance, preventing the structure from deforming and providing parallel supporting force for the guide wheels.

Furthermore, the space supporting frame is connected with more than two space supporting frames at intervals in the length direction of the rope passing groove, a plurality of groups of shaft holes corresponding to the guide wheels in number are oppositely formed in the car bottom beam and the wheel frame, and a wheel shaft is concentrically arranged between each group of shaft holes and penetrates through the shaft holes. The shaft holes are arranged oppositely, so that the rotating shaft of the guide wheel is horizontally arranged, the stress of the passing traction rope is uniform, the stability in operation is good, and the traction rope is not easy to shake.

Furthermore, the car bottom beam is provided with a working hole on the other side edge relative to the shaft hole, the opening surface of the working hole corresponds to the position of the shaft hole, and the area of the opening surface is larger than that of the shaft hole. The outside of being convenient for from the sedan-chair floorbar during the effect of working hole touches inside, conveniently stretches into the instrument, plays convenient effect to the installation and the maintenance of pivot and other structures.
