Description

Technical Field

[0001] The utility model belongs to the technical field of live working tools, and in particular relates to a line paralleling auxiliary tool for live working. Background Art

[0002] Currently, in 10kV overhead lines, when connecting live lines or disconnecting grid-connected conductors, workers operate in insulated boom trucks. Although they use safety protection measures such as insulating gloves, the safe distance between different potentials cannot be guaranteed when the lines are connected or disconnected. The arc generated by the running lines and the grid-connected lines may cause the human body to be connected to the electric field, resulting in personal injury or death.

[0003] Therefore, measures need to be taken to prevent the arc generated when breaking and connecting the lead from entering the human body. Utility Model Content

DETAILED DESCRIPTION

[0024] To better understand the present invention, the following examples and accompanying drawings further illustrate the present invention. However, the present invention is not limited to the following examples. In the following description, numerous specific details are provided to provide a more thorough understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without one or more of these details.

[0025] Example 1: See Figure 1-Figure 2 The present embodiment aims to provide a line-joining auxiliary tool for live working, comprising a first clamping portion 1, a second clamping portion 2, a first insulating rod 3 fixedly connected to the first clamping portion 1, and a second insulating rod 4 threadedly connected to the second clamping portion 2.

[0026] Specifically, the first clamping portion 1 and the second clamping portion 2 are both provided with an opening on the same side, and the openings of the first clamping portion 1 and the second clamping portion 2 face the same direction. A first slider 11 is provided within the opening of the first clamping portion 1, and a second slider 21 is provided within the opening of the second clamping portion 2. The first slider 11 and the second slider 21 are generally square, with one side of the interior capable of sliding along the inner wall of the opening. A first rotating handle 12 is threadedly connected to the top of the first clamping portion 1, the end of which is also rotatably connected to the first slider 11. The upper end of the second insulating rod 4 is threadedly connected to the bottom of the second clamping portion 2 via a stud, the end of which is also rotatably connected to the second slider 21. Rotating the first rotating handle 12 drives the first slider 11 to slide up and down within the opening; rotating the second insulating rod 4 drives the second slider 21 to slide up and down within the opening. The first clamping portion 1 utilizes the first slider 11, and the second clamping portion 2 utilizes the second slider 21 to clamp the wire. Furthermore, arc-shaped grooves are provided on the clamping surfaces of the first sliding block 11 and the first clamping portion 1 , and on the clamping surfaces of the second sliding block 21 and the second clamping portion 2 .

[0027] The upper end of the first insulating rod 3 is fixedly connected to the other side of the first clamping portion 1, while the other side of the second clamping portion 2 is slidably mounted on the first insulating rod 3. The second insulating rod 4 is parallel to the first insulating rod 3. A second sleeve 5 is fixedly mounted on the end of the first insulating rod 3 and slidably mounted on the second insulating rod 4. Therefore, the second sleeve 5 limits the position of the second insulating rod 4, allowing it to slide up and down along the first insulating rod 3 while carrying the second clamping portion 2 without deflection.

[0028] A first sleeve 22 is fixedly provided on the side of the second clamping portion 2 facing the second insulating rod 4. The first sleeve 22 is coaxial with the second insulating rod 4 and is slidably sleeved on the second insulating rod 4. It can provide circumferential limiting support for the end of the second insulating rod 4 to prevent the stud at the end of the second insulating rod 4 from being bent due to excessive force.

[0029] A second rotating handle 41 is vertically fixedly provided at the free end of the second insulating rod 4 , and the second insulating rod 4 can be conveniently rotated using the second rotating handle 41 .

[0030] The second sleeve 5 is also provided with a screw hole 51, and a screw pin 6 is provided in cooperation with the screw hole 51. When the second clamping portion 2 moves up to the top and abuts the first clamping portion 1, the screw pin 6 is tightened in the screw hole 51, and the screw pin 6 abuts the second insulating rod 4, thereby fixing the second insulating rod 4 to prevent it from sliding.

[0031] The first insulating rod 3 is also provided with a socket 31, and a latch 7 is provided in cooperation with the socket 31. When the second clamping portion 2 moves up to the top and abuts the first clamping portion 1, the socket 31 is close to the bottom side of the second clamping portion 2. At this time, the latch 7 is inserted into the socket 31 to fix the second clamping portion 2 to prevent it from sliding.

[0032] One end of the screw pin 6 and the latch pin 7 are fixedly provided with a ring for easy use; at the same time, the screw pin 6 and the latch pin 7 are also tied to the first insulating rod 3 or the second insulating rod 4 by a thin rope to avoid loss.

[0033] When using the present invention to perform a line connection operation in an insulated boom truck, construction workers first raise the boom truck and clamp the first clamping part 1 onto the running conductor. After lowering the boom truck to a safe distance, the new grid-connected conductor is clamped onto the second clamping part 2. The second insulating rod 4 is then operated to push the second clamping part 2 to the top, and the screw 6 is screwed into the screw hole 51 to secure the second insulating rod 4. Finally, the boom truck is raised to perform the line connection operation. After the line connection is completed, the first clamping part 1 and the second clamping part 2 are loosened. During the line connection operation, the pin 7 can be inserted into the socket 31 to secure the second clamping part 2 to prevent it from slipping out.

[0034] When it is necessary to disconnect the grid-connected conductor, push the second clamping part 2 to the top, screw in the screw 6, and insert the pin 7; raise the insulating boom truck, clamp the first clamping part 1 on the running conductor, clamp the second clamping part 2 on the grid-connected conductor to be disconnected, and remove the grid-connected conductor to be disconnected; finally, pull out the pin 7 in the socket 31, lower the insulating boom truck, and then unscrew the screw 6 in the screw hole 51, operate the second insulating rod 4 to drive the second clamping part 2 to descend to a safe distance, and then loosen the second clamping part 2; raise the insulating boom truck and loosen the first clamping part 1.

[0035] The lengths of the first insulating rod 3 and the second insulating rod 4 of the present invention are both about 1.2m-1.5m, ensuring that people have a sufficient safety distance to avoid arcs generated when disconnecting and connecting the lead wires from penetrating the human body.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model and are not limiting. Other modifications or equivalent substitutions made to the technical solution of the utility model by ordinary technicians in this field should be included in the scope of the claims of the utility model as long as they do not depart from the spirit and scope of the technical solution of the utility model.
