Description

Technical Field

[0001] The utility model relates to the technical field of bridge crane busbar installation equipment, in particular to a bridge crane busbar fixing device. Background Art

[0002] The busbar is a power transmission device used to power mobile equipment. It is often used in mobile equipment such as bridge cranes, gantry cranes, and gantry cranes. Usually, the busbar is laid parallel to several conductive tracks along the tracks of the mobile equipment to keep the power supply on. The conductive track is made up of several sections of track. At the same time, a collector that can draw power from the conductive track is fixed on the mobile equipment. When the equipment moves, the collector runs synchronously with the equipment and obtains the required power from the conductor at any time for its own use, so that the mobile equipment can be moved at any time.

[0003] Usually, the busbar is fixed by installing a busbar cantilever bracket on the bridge crane track beam or wall, and the cantilever bracket is then fixed with bolts to several conductive rails located below it, so that the overall structure remains firm and stable. Although this method is adopted by most mines and factories, since the conductive rails are installed and adjusted in sections, it requires the use of high-altitude operation equipment such as lifts and scaffolding, and it is inconvenient to operate and adjust at high altitudes. Secondly, the position of the traditional busbar bracket is a fixed point and cannot be moved. Because it cannot effectively balance the location of the conductive rail joint, the conductive rail has a low cross-sectional stiffness and is easily deformed, resulting in some busbars being arched or bent after installation, which increases the abnormal friction between the collector slider and the conductive rail, affecting the life of the collector on the mobile equipment.

[0004] Therefore, it is necessary to propose a bridge crane busbar fixing device to solve the problems of inconvenient adjustment during high-altitude operation, insufficient horizontality of the conductive track, and upward or downward bending. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a fixing device for the busbar of a bridge crane, so as to solve the potential safety hazards in high-altitude operation, and the problems that the levelness of the conductive track is insufficient, and there is an upward arch or downward deflection.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is: a bridge crane busbar fixing device, the bridge crane includes a crane track beam, a cantilever bracket, a conductive track, a collector device bracket and a mobile device, including an adjustment track and a connector;

[0007] outrigger, with the left end connected to the crane track beam;

[0008] Adjust the track and set it below the cantilever bracket;

[0009] A connecting piece, one end of which is connected to the lower side of the adjustment track, and the other end of which is provided with a plurality of connecting grooves and connected to the conductive track;

[0010] Conductive rails are connected to the mobile equipment via collector brackets.

[0011] As a further technical solution of the above solution, there are multiple connecting members.

[0012] As a further technical solution of the above solution, a mounting groove is provided on the bottom surface of the adjustment rail, which is connected to the upper part of the connecting piece through a pressure plate bolt.

[0013] As a further technical solution of the above scheme, the connecting piece is Z-shaped, with the upper end connected to the adjustment rail and the lower end provided with a plurality of connecting holes, and the bolts pass through the connecting holes and then fix the connecting grooves.

[0014] As a further technical solution of the above solution, gaskets are further provided at the upper and lower connecting parts of the connecting piece.
