Problems solved by technology

Even if the cable is pulled over, the outer sheath has a large deformation, especially at the end of the cable under the action of the net sleeve, the deformation is serious, and the damage needs to be repaired, which reduces the quality of the cable. During the process, if there is water in the pipeline and the sealing cap of the cable end is scratched (scratched) by the residue in the pipeline, the cable will enter the water, which will bring great inconvenience to the construction and cause hidden dangers to the quality of the power project.
At present, there is no traction device that can well act on the metal conductor of the multi-core cable and the method of pulling the multi-core cable with this device

Embodiment Construction

[0012] During the specific operation, first strip and cut off the sheath, steel strip (if any), filler, etc. strip and cut off together), expose the cable conductor by 60~120mm, use a crimping tool (commonly used crimping pliers) to crimp the crimping piece 1 and the cable conductor together, and then screw the crimping piece 1 and the intermediate connecting piece 2 in turn Connection (intermediate connector 2 can be screwed in or out to form an angle of 120 degrees, 90 degrees or 72 degrees according to the number of cores of the cable is 3 cores, 4 cores or 5 cores), intermediate connectors 2 and the traction base 5 are bolted through the screw 3 and the nut 4, the traction base 5 is threaded with the sleeve 6, and the sleeve 6 is connected with the traction hook 8 through the nut 7 bolts. If there is water in the cable duct, PE self-adhesive tape and other strips can be used to simply wrap the outer surface of the traction base 5 to the surface of the outer sheath of the c...

Abstract

The invention provides a device and a method for towing a multi-core cable, and belongs to the technical field of electromechanical products. The device comprises a compression connection component, an intermediate connection component, a towing base, a sleeve and a towing hook. The device is characterized by convenient assembly and disassembly and towing force on the cable conductors. The method comprises the following steps: making a cable head, connecting the cable head with the device, and finally hanging a steel cable on the device. The method is characterized by finishing the connection and assembly by general-purpose tools and standard components, providing simple operation and being applicable to site operation. The device and the method for towing the multi-core cable can tow cables with huge towing force, the multi-core conductors are stressed evenly, and cables are not damaged. The assembly and disassembly are convenient, and the compression connection components can be flexibly used together with conductors with different specifications. PE self-adhesive tapes wrap the cables to prevent water entering the cables during towing the cables.

Description

technical field [0001] The invention relates to the technical field of electromechanical products, in particular to a traction device for laying and setting out a multi-core cable and a method for pulling the multi-core cable with the device. Background technique [0002] At present, the laying and setting-out of multi-core cables mostly use the net sleeve to act on the outer sheath of the cable. Since the outer sheath material of the cable is mostly non-metallic material, its tensile strength is small, so the traction force cannot be applied large enough, so that It often happens that the outer sheath of the cable has been torn or stretched a lot, but the cable still cannot be pulled. Especially for longer lines, it is more obvious. Even if the cable is pulled over, the outer sheath has a large deformation, especially at the end of the cable under the action of the net sleeve, the deformation is serious, and the damage needs to be repaired, which reduces the quality of the...
