TECHNICAL FIELD
[0001] The utility model relates to rail transit technical field, especially a rigid catenary contact wire quick replacement device. BACKGROUND
[0002] The overhead rigid contact suspension mode is widely used in the subway industry, and for the rigid catenary power supply subway section, there are aluminum rigid pi-shaped busbars and contact wires clamped by the pi-shaped busbars in the tunnel. Due to the electrical corrosion between the contact wire and the locomotive carbon slide plate, the mechanical friction of the pantograph carbon slide plate, chemical corrosion, and contact wire oxidation, the copper-silver alloy rigid catenary contact wire is worn to varying degrees. In the traditional maintenance operation, the rigid catenary contact wire with local severe wear is usually replaced.
[0003] The traditional rigid catenary contact wire replacement operation has the following difficulties and pain points:
[0004] Long operation time: the traditional contact wire replacement operation adopts the process of first removing the existing old contact wire, then installing the new contact wire. This replacement method cannot simultaneously carry out the old contact wire removal and new contact wire installation processes, and the operation team needs to come back and forth to the operation area, which takes a long time to replace the contact wire and is low in efficiency.
[0005] Old line breaking difficulty: the traditional old contact wire removal usually uses manual breaking with wire clippers, which is low in efficiency and seriously affects the operation efficiency.
[0006] New line straightening difficulty: before the new contact wire is installed into the expansion element, the insulation anchor section joint, and other special positions, the traditional method needs to use a contact wire straightening device to straighten the new contact wire, so that the contact wire can be more easily installed into the clamping groove. The stress of the straightened contact wire after entering the groove is reduced, reducing the risk of contact wire popping out of the groove. The contact wire straightening process needs to constantly straighten the contact wire back and forth, which takes a long time and has certain difficulty.
[0007] Clamping groove cleaning difficulty: before installing the new contact wire, the π-shaped busbar clamping groove needs to be cleaned to avoid the influence of foreign matter in the clamping groove on the new contact wire entering the groove. The traditional method uses a special person to clean the π-shaped busbar clamping groove with a brush.
[0008] High safety risk: when the traditional line cutting pliers are used to manually cut the line, a dedicated person is arranged to guide and assist in cutting the old contact line, and in the process of guiding and cutting, the contact line is easy to pop out and cause injury, so the safety risk is high. High safety risk: when the traditional method is used to replace the contact line, if the quality problem occurs during the installation of the contact line, the old contact line has been completely removed, which will seriously affect the operation safety, so the safety risk of the contact line replacement construction is high.
