Description

Technical Field

[0001] The utility model relates to the technical field of track cranes, in particular to a track crane horizontal wheel reinforcement tooling. Background Art

[0002] The rail-mounted container gantry crane (railway crane) is composed of a main beam, rigid and flexible gantry legs, a running trolley, a lifting mechanism, a trolley running mechanism, an electrical system, an operating cab, etc.; according to the yard operation process, the cantilever is extended in the direction of the single gantry or double gantry to become a single-cantilever or double-cantilever model, and the model without extension becomes a cantilever-free model; different structural forms such as no cantilever, single cantilever and double cantilever are determined according to the site, container storage and transportation process and the loading and unloading vehicles (container trucks or railway vehicles).

[0003] At present, the trolleys of rail-mounted container gantry cranes generally adopt a design in which flangeless wheels contact the rails, and a guide device (horizontal wheel) is added to the side of the rails. The horizontal wheels can reduce the processing errors in the production process and reduce the impact of the track gauge changes on the trolley operation when the trolley is loaded.

[0004] However, the horizontal wheel is installed on one side, that is, an axis extends from the frame of the rail crane, and the horizontal wheel is installed on the axis. During operation, the movement, braking and other operations of the rail crane will cause impact on the horizontal wheel. Since the horizontal wheel is installed on one side, there is no fixed point below the horizontal wheel, which will cause uneven force on the horizontal wheel, causing the lower part of the axis to shift, and causing abnormal wear of the bearing inside the horizontal wheel. As the bearing wear increases, the rail crane will shake, and it may also cause the container to fall. For this reason, a rail crane horizontal wheel processing tooling is needed to solve the above problems. Summary of the invention

[0005] Aiming at the problem that the installation shaft of the horizontal wheel of the track crane is unevenly stressed, which leads to abnormal wear of the internal bearing of the horizontal wheel, the utility model proposes a track crane horizontal wheel reinforcement tooling to solve the above problem.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is a kind of track crane horizontal wheel reinforcement tooling, including a track crane frame, a mounting shaft is installed on the track crane frame, a horizontal wheel is installed on the mounting shaft, a reinforcement plate is arranged at the bottom of the horizontal wheel, the reinforcement plate is fixed to the track crane frame, the top of the reinforcement plate is rotatably connected to the mounting shaft, when in use, the bottom of the mounting shaft is also provided with a fixed point through the reinforcement plate, when impacted, the impact force is absorbed by the reinforcement plate, which can effectively prevent the lower part of the mounting shaft from shaking, thereby preventing abnormal wear of the internal bearing of the horizontal wheel, increasing the service life of the horizontal wheel, thereby preventing the track crane from shaking, and the overall use effect is good.

[0007] Furthermore, the reinforcement plate is treated by a heat treatment process. Through the heat-treated reinforcement plate, the strength and toughness of the reinforcement plate can be enhanced, and the performance of the reinforcement plate in coping with impact can be improved.

[0008] Furthermore, the reinforcement plate and the track crane frame are connected by plugging.

[0009] Furthermore, the reinforcement plate is fixed to the track crane frame by fixing screws, and the fixing screws are used to facilitate the removal of the reinforcement plate.

[0010] Furthermore, the top of the reinforcement plate is coated with a wear-resistant coating, and the wear-resistant performance of the reinforcement plate is further enhanced by the wear-resistant coating.

[0011] Furthermore, the reinforcement plate is located in the middle of the side of the track. By virtue of the reinforcement plate being located in the middle of the side of the track, interference with the operation of the track crane caused by the reinforcement plate can be avoided.

[0012] The beneficial effects of the utility model are:

[0013] The reinforcement tooling uses the reinforcement plate to provide a fixed point at the bottom of the installation shaft. When impacted, the reinforcement plate absorbs the impact force, which can effectively prevent the lower part of the installation shaft from shaking, thereby preventing abnormal wear of the internal bearing of the horizontal wheel and increasing the service life of the horizontal wheel. At the same time, it can reduce the replacement frequency of the horizontal wheel, reduce the company's operating costs, and further increase corporate profits. The overall use effect is good, and it is suitable for the transformation of existing rail cranes. It is highly practical and suitable for promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS
