The three support rods are telescopic sleeve rods, and the telescopic sleeve rods are fastened by bolts.

The double-hook wire tightener includes a housing, a positioning hook, a hanging hook, a ratchet pawl, a rocker and a steel cable. One end of the housing is provided with a positioning hook, and the ratchet pawl is arranged in the housing. One end is hinged, the rocker is set on the ratchet shaft, the ratchet is connected to one end of the steel cable through a key, and the other end of the steel cable is connected to the hook.

The sling is a load-bearing flat belt.

The utility model has the following advantages:

1. Simple and convenient to use, easy to disassemble; a single person can complete the work of assembling and disassembling the cable head, saving manpower and time; successfully replacing the way of manpower pulling the cable obliquely upwards.

2. Both the tripod and the lifting belt can be adjusted, which is suitable for various cabinets and general cable models.

3. The top of the tripod has a rotation function, which can realize 360° rotation, and it is convenient to adjust the angle; the telescopic part of the support rod is fixed with fastening bolts, which is firm and reliable; the bottom end of the support rod adopts a tapered design, which is convenient to stabilize at the load-bearing tension bar of the cabinet .

4. It is connected and operated by mechanical methods, and is not affected by weather and climate. It can be used in various environments outdoors and indoors. It is small in size and easy to carry, and can be carried by one person.

detailed description

Example

As shown in the figure, the 10kV cable head disassembly and assembly auxiliary tool includes a tripod 3, a double hook tensioner 4 and a hanging belt 5; , the hook 403 of the double-hook wire tightener connects one end of the sling belt 5, and the other end of the sling belt 5 binds the cables.

Described tripod comprises top nut 301, screw head 302, three support rods 303 and hanging ring 304, wherein the welding hanging ring 304 below screw head 302, top nut 301 connects the top of three support rods 303, three support rods 303 The bottom end of the tripod is a tapered foot, and a bearing is set between the nut and the screw head, so that the 360° rotation of the tripod is realized.

The three support rods are telescopic sleeve rods, and the telescopic sleeve rods are fastened by bolts 305 .

The double-hook wire tensioner includes a housing 401, a positioning hook 402, a hanging hook 403, a ratchet pawl, a rocker 405 and a steel cable 406. One end of the housing 401 is provided with a positioning hook 402, and the ratchet pawl is arranged in the housing. , the ratchet is hinged with one end of the rocker 405, the rocker 405 is sleeved on the ratchet shaft, the ratchet 404 is connected to one end of the cable 406 through a key, and the other end of the cable is connected to the hook 403; the maximum extension distance of the double hook tensioner is 150mm, the cable is adjusted through the ratchet. The longest cable can be released to 150mm.

The tripod is made of fiberglass epoxy resin, with a compressed length of 470mm and a fully extended length of 670mm. The tapered feet can be firmly fixed on the load-bearing ribs of the cabinet frame, and the angle and height of the tripod can be adjusted according to the actual position of the cable and the specifications of the cabinet with different cable heads. The maximum release and tightening distance of the double hook tensioner is 150mm, and the maximum lifting capacity is 2 tons. The lifting belt is made of load-bearing flat belt, and the maximum lifting weight is 2.5 tons. Fix the cable head and hang it on the tensioner, which is suitable for 10kV cables 50~300mm². It replaces the previous method of manually dragging the rope.

Operation process: First, fix the tripod in the cable head cabinet, and adjust the tripod to a suitable position. Then hang the double hook tensioner on the ring on the top of the tripod and adjust the cable to a suitable length. Finally, bind the cable with a sling, and hang the other end of the cable on the hook of the cable tensioner. (1) When removing the cable head, hang the cable, remove the connecting bolts, and gradually lower the cable with a wire tensioner to a distance that can meet the high-voltage test. (2) When installing the cable head, use the wire tightener to gradually lift the cable, so that the cable head terminal can be easily aligned with the bolt joint and lock the bolt. Finally loosen the tensioner and remove the auxiliary tool.
