Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a car frame structure. Background Art

[0002] The car frame structure of a machine-roomless high-capacity high-speed elevator usually adopts a double car top wheel structure. This structure is relatively simple, safe and reliable, and is a common structure in elevator structure design. However, when this structure is applied to the elevator design of a machine-roomless high-capacity high-speed elevator, the following problems exist:

[0003] 1. Because the elevator runs at a high speed and has a large load, this structure cannot maintain a flat heel during startup and operation, and cannot give customers a good riding experience;

[0004] 2. This structure occupies a large top floor space and cannot meet the requirements of a hoistway with a relatively small top floor space size.

[0005] 3. The roller guide shoes of this structure are installed on the upper beam. In order to meet the requirement that the projection plane of the car traction machine is outside the car (otherwise the top floor space will be increased), the car top return pulley must be arranged at both ends of the car width as much as possible, which will cause the guide shoes to interfere with the wire ropes of the car top wheels.

[0006] In order to solve the above problems, this application discloses a car frame structure. Content of the Utility Model

[0007] To overcome the deficiencies of the prior art, the utility model discloses a car frame structure.

[0008] To achieve the above object, the technical solution adopted by the utility model is: a car frame structure, comprising: two floating upper beams, which are arranged in parallel with each other;

[0009] Two fixed upper beams, which are respectively fixed on the outer sides of the two floating upper beams through shock absorption components;

[0010] Two car top wheels, which are respectively arranged between the opposite sides of the two floating upper beams;

[0011] Two groups of roller guide shoes, which are respectively fixed under the opposite sides of the two fixed upper beams through connecting pieces;

[0012] Two groups of vertical beam components, which are respectively fixed on the outer sides of the opposite sides of the two fixed upper beams. Each group of vertical beam components includes a vertical beam a fixed to one fixed upper beam and a vertical beam b fixed to the other fixed upper beam.

[0013] Further preferably, it further includes two protective plates respectively fixed between the two floating upper beams above the two car top wheels.

[0014] Further preferably, bending portions are formed downward on both opposite sides of the two protective plates, and the two bending portions are respectively fixed to the two floating upper beams by bolts.

[0015] Further preferably, the two fixed upper beams are of a hollow structure and are both open on the sides away from each other, and a number of reinforcing vertical beams are arranged inside the two fixed upper beams.

[0016] Further preferably, a U-shaped groove is formed outward at the bottom of the floating upper beam. The shock absorption assembly includes an upper rubber shock absorption block and a lower rubber shock absorption block. The upper rubber shock absorption block is arranged on the inner bottom side of the U-shaped groove. The fixed upper beam is fixed above the lower rubber shock absorption block within the U-shaped groove. The upper rubber shock absorption block is arranged on the inner bottom side of the floating upper beam. The upper rubber shock absorption block, the floating upper beam, the lower rubber shock absorption block and the fixed upper beam are fixed by bolts.

[0017] Further preferably, the two connecting pieces are respectively fixed to the lower sides of the two fixed upper beams by bolts, and the upper plate members of the two roller guides are respectively fixed to the two connecting pieces by bolts.

[0018] Further preferably, right-angle connecting seats are respectively arranged on both lower sides of the two connecting pieces, and the right-angle connecting seats and the connecting pieces are fixed to the fixed upper beam by bolts together.

[0019] The present utility model achieves the following beneficial effects:

[0020] 1. In this application, the upper beam is designed as a fixed upper beam and a floating upper beam, which are connected by a shock absorption assembly in the middle.

[0022] 3. The vertical beam assembly structure designed in this application installs the roller guide at the lower position to solve the problem of interference between the roller guide and the steel wire rope of the car top deflecting sheave.
