Description

Technical Field

[0001] The utility model relates to the technical field of festoon cables, in particular to an auxiliary tool for replacing festoon cables. Background Art

[0002] In the power and communications industries, trolleys are important equipment used to carry and transmit cables on rails. However, as the equipment ages or as technology upgrades, trolley cables and trolleys often need to be replaced.

[0003] In the prior art, when replacing the trolley cable and the trolley cable pulley assembly, since the trolley cable and the trolley cable pulley are an integral part, the staff needs to disassemble the trolley cable and the trolley cable pulley, use a special lifting tool to transport the old trolley cable and the trolley cable pulley to the ground for repair or replacement, and after the repair, replacement and assembly on the ground are completed, the new trolley cable and the trolley cable pulley are lifted by the lifting tool, and the operator then installs the new trolley cable and the trolley cable pulley.

[0004] The rubber-tyred container gantry crane is a special machine for stacking container cargo. For the rubber-tyred container gantry crane, the trolley cable is relatively long and is installed on a 24-meter-high trolley cable pulley. Due to the open-air operation, the trolley cable and the trolley cable pulley are exposed to wind, rain, sun and rain for a long time, and the trolley cable and the trolley cable pulley are more prone to failure. In order to ensure the normal operation of the trolley cable and the trolley cable pulley, more frequent and careful maintenance is required. However, if the existing method of repairing or replacing the trolley cable and the trolley cable pulley is adopted, it will bring higher safety risks of high-altitude operations and the labor intensity is also relatively large.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] An auxiliary tooling for replacing a trolley cable comprises a main body, the main body comprises a hanging rail, a hanging cabinet comprises a first horizontal plate, a vertical plate is vertically connected to the plate surface of the first horizontal plate, and the length direction of the vertical plate is consistent with the length direction of the first horizontal plate; a plurality of lifting ears are connected to the side of the vertical plate away from the first horizontal plate, the lifting ears are provided with lifting holes, and the plurality of lifting ears are distributed along the length direction of the vertical plate; the width of the first horizontal plate is consistent with the width of the running track of the trolley cable.

[0021] As a preferred implementation of the auxiliary tooling for replacing the festoon cable, a plurality of horizontal limit holes are provided, and the plurality of horizontal limit holes are distributed along the height direction and / or the length direction of the vertical plate.

[0022] The above structural solution is adopted to further improve the strength and reliability of the limiting structure.

[0023] As a preferred implementation method of auxiliary tooling for replacing a trolley cable, mounting plates are provided on the upper and lower sides of one end of the second horizontal plate, and both mounting plates protrude from the end of the second horizontal plate along the length direction of the second horizontal plate.

The hanging rail and the running track of the trolley cable can be temporarily clamped together, which is convenient for improving the stability when pushing and releasing the trolley cable.
