Description

Technical Field

[0001] The utility model relates to equipment machinery for rail transportation, in particular to a lifting and lowering device. Background Art

[0002] The pre-installation, press-fitting or unloading of train wheels requires the axle or wheelset to be lifted up and coaxial with the main machine working head to complete the corresponding work. It is understood that currently this work is basically completed using a special trolley. Although it can meet production needs, it still cannot meet the needs of the market and customers. Summary of the invention

[0003] In order to solve the deficiencies in the prior art, the utility model provides a lifting and supporting device which has a scientific and reasonable structure and can replace a trolley to lift and support axle wheel pairs.

[0004] In order to achieve the above-mentioned purpose, the technical solution of the utility model is a lifting and supporting device, which is composed of two working heads, and the two working heads are coaxially arranged correspondingly;

[0005] The working head is composed of a slide, a motor reducer, a lifter, a lifting plate, and a guide assembly; the motor reducer is arranged on the slide, the motor reducer is sequentially connected to the lifter and the lifting plate, a support block is arranged on the lifting plate, and the guide assembly is arranged between the slide and the lifting plate;

[0006] The lifting plate is a strip-shaped upright plate on one of its working heads, and a support seat is provided in front of the strip-shaped upright plate;

[0007] The lifting plate is a shovel-shaped plate on its other working head, and a pressure arm is arranged on the shovel-shaped plate, and the pressure arm is connected with an oil cylinder.

[0008] The guide assembly is a guide rail and guide groove pair.

[0009] The support block is made of nylon material.

[0010] The beneficial effects of the utility model are that it can replace the trolley to lift and support the axle wheel pair, has a scientific and reasonable structure, is easy to produce, manufacture, install and adjust. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] 100 A lifting and supporting device;

[0020] 1 working head, 11 sliding seat, 12 motor reducer, 13 lifting machine, 14 guide assembly (guide rail and guide groove pair), 15 supporting block, 16 strip upright plate (lifting plate), 17 supporting seat, 18 spear-shaped plate (lifting plate), 19 pressing arm, 20 oil cylinder. DETAILED DESCRIPTION

[0021] The following describes embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0022] like Figures 1 to 7 As shown, the utility model discloses a lifting and supporting device 100, which is composed of two working heads 1, and the two working heads are arranged correspondingly on the same axis; the two working heads can be adjusted laterally and vertically separately to achieve lateral movement and lifting;

[0023] The working head 1 is composed of a slide 11, a motor reducer 12, a lifter 13, a lifting plate, and a guide assembly 14; the motor reducer is arranged on the slide, and the motor reducer is sequentially connected to the lifter and the lifting plate, and a support block 15 is arranged on the lifting plate, and the guide assembly is arranged between the slide and the lifting plate; the slide is matched with the base of the working main machine, and a guide rail and guide groove pair can be arranged between the slide and the base to realize free lateral movement;

[0024] The lifting plate is a strip-shaped upright plate 16 on one working head, and a support seat 17 is provided in front of the strip-shaped upright plate; the support seat is used to lift the gear box (the wheelset is provided with a gear box).

[0025] The lifting plate is a shovel-shaped plate 18 on its other working head, and a pressure arm 19 is provided on the shovel-shaped plate. The pressure arm is connected to an oil cylinder 20. When working, the pressure arm presses the axle to make it immobile and successfully completes the assembly and disassembly of the wheelset.

[0026] The guide assembly is a guide rail and guide groove pair.

[0027] The support block is made of nylon material to prevent damage to the axle.

[0028] The above is only one of the embodiments of the present invention and is not intended to limit the present invention. Although the present invention is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions described in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
