Description

Technical Field

[0001] The utility model relates to the field of live working tools, in particular to an operating tool for a live wiring clamp. Background Art

[0002] The live operating wire clamp in the prior art, such as the power wire clamp with publication number CN213637014U disclosed on publication date 2021-07-06, has two operating parts arranged at intervals and a constant torque connecting part arranged between the operating parts at the lower end of the screw.

[0003] In addition, the live wire clamp operating tool, such as the emergency live wire handling device with publication number CN204464936U and publication date 2015-07-08, includes a bracket with an opening on one side, a pressure block, a conductive connector, and an adjusting screw. The pressure block is slidably arranged on the bracket, and the two ends of the conductive connector are respectively connected to the bracket and the pressure block. The adjusting screw is installed on the bracket in a liftable manner. One end of the adjusting screw is fixedly connected to the pressure block, and the other end is connected to a holding portion. The holding portion includes a sleeve and an insulating rod for detachably connecting to the adjusting screw. The sleeve and the insulating rod are fixedly connected. The connection between the sleeve and the screw in this structure is unstable. It is possible that after the wire clamp is hung on a high wire, the sleeve and the screw are accidentally separated, and the operator has to re-align them. At this time, it is very difficult to align the wire clamp with the holding portion. Therefore, these existing structures have the disadvantage of poor practicality. Utility Model Content

[0004] In order to overcome the shortcomings of the background technology, the utility model provides an operating tool for a live wiring clamp which is simple to operate and has good practicality.

[0005] The technical solution adopted by the utility model is: an operating tool for a live wiring clamp, which comprises:

[0028] The embodiments of the present utility model will be further described below with reference to the accompanying drawings:

[0029] As shown in the figure, an operating tool for a live wiring clamp includes:

[0030] A remote control wrench 2, which is used to link and drive the screw rod at the lower end of the wiring clamp;

[0031] A connecting frame 3, the upper end of which is used to sleeved on the wiring clamp and the lower end of which is fixedly connected to the remote control wrench 2;

[0032] A locking mechanism 4, which is installed on one side of the connecting frame 3;

[0033] The locking mechanism 4 has a first state in which it is horizontally inserted to lock the remote control wrench 2 and the screw rod at the lower end of the wiring clamp, and a second state in which the locking is released after being pulled out; in the technical solution of the present application, the screw rod and the remote control wrench are linked. By remotely controlling the rotation of the remote control wrench, the remote control wrench, as a driving member, can drive the screw rod to rotate, so as to realize the clamping of the cable by the pressing block, which has the advantages of simple operation, time saving and labor saving;

[0034] When the wiring clamp is lifted and not hung on the cable, the connecting frame plays an auxiliary role to ensure that the remote control wrench and the wiring clamp are in the same straight line and will not be bent; the locking mechanism can connect the screw rod and the remote control wrench together to prevent them from separating; it has the advantage of good working stability;

[0035] After the wiring clamp is hung on the cable, remotely control the remote control wrench to increase the power, so that it twists off the lower end position of the screw rod with a large torque. After twisting off, the connecting frame and the wiring clamp body can be freely separated, which has the advantage of good practicability.

[0036] Wherein, a long rod (not shown) for holding is also connected to the lower end of the remote control wrench.

[0037] The upper end of the remote control wrench 2 is provided with a sleeve 21 which is sleeved and matched with the screw rod at the lower end of the wire clamp; the remote control wrench has a normal mode and a high torque mode. When the normal mode is selected, the sleeve sleeves the operating part at the lowermost end of the screw rod, drives the screw rod to rotate, and gradually raises the pressing block to press the wire tightly. After pressing, the remote control switches to the high torque mode, the torque transmitted by the sleeve to the operating part at the lowermost end of the screw rod becomes larger, the fixed torque connecting part is broken, and the screw rod is separated from the remote control wrench.

[0038] In addition, after breaking, the remaining operating part on the screw rod is used for the next disassembly.

[0039] The material of the screw rod 11 is aluminum, which has the advantages of being light, good in processing performance, and easy to break.

[0040] The locking mechanism 4 includes:

[0041] A locking frame 41 which is slidably installed in the connecting frame 3;

[0042] A connecting rod 42, one end of which passes through the side wall of the connecting frame 3 and is connected to the locking frame 41, and the other end is provided with a handle 43;

[0043] The locking frame 41 extends forward to form a fork frame 44 for preventing the separation of the sleeve 21 and the screw rod at the lower end of the wire clamp; after the sleeve and the operating part are connected, the operator pushes the fork frame of the locking frame between the two operating parts through the handle and the connecting rod. As shown in the figure, the fork frame plays a limiting role on the operating part to prevent the separation of the operating part 12 and the sleeve 21.

[0044] The locking mechanism 4 further includes an elastic member 45 sleeved on the connecting rod 42. The two ends of the elastic member 45 respectively abut against the handle 43 and the side wall of the connecting frame 3. The elastic member is a spring, which provides an elastic pre-tightening force for the locking frame to leave between the two operating parts.

[0045] The connecting frame 3 is provided with a plurality of guide grooves 31, and the lower part of the locking frame 41 is provided with a plurality of guide rods 46 which are slidably matched with the guide grooves 31. The cooperation of the guide grooves and the guide rods can ensure that the fork frame accurately inserts into the fixed torque connecting part between the two operating parts, and has the advantage of good working stability.

[0046] The connecting rod 42 includes a baffle portion 421 and a main shaft portion 422 arranged coaxially. The width dimension of the baffle portion 421 is greater than the outer diameter dimension of the main shaft portion 422. The side wall of the connecting frame 3 is provided with a first hole 32 adapted to the baffle portion 421 and a second hole 33 adapted to the main shaft portion 422. The first hole 32 and the second hole 33 are concentrically arranged. When the baffle portion passes through the first hole and is inserted into the connecting frame, when the connecting rod rotates, the baffle portion will also rotate around the axis. At this time, there is an angle between the baffle portion and the first hole, and the side wall surface of the connecting frame plays a limiting role on the baffle portion, so that the baffle portion will not withdraw from the connecting frame under the action of the elastic member.

[0047] The connecting frame 3 is provided with a limit bolt 34 with a threaded fit at a position on one side of the locking mechanism 4. When the locking mechanism 4 is in the first state, the limit bolt 34 is in contact and cooperation with the baffle portion 421 to prevent the baffle portion 421 from rotating. When the locking mechanism is in the first state, there is an angle between the baffle portion and the first hole. In order not to allow the baffle portion to rotate and thus withdraw from the connecting frame through the first hole, a limit bolt is provided in this embodiment. The end of the limit bolt abuts against the baffle portion to prevent it from rotating and ensure the working stability of the locking mechanism.

[0048] The connecting frame 3 is provided with a limit block 35 for limiting the rotation of the baffle portion 421 directly in front of the limit bolt 34. After the baffle portion rotates to an angle adapted to the first hole, it passes through the side wall of the connecting frame and enters the inside of the connecting frame, and then the baffle portion is rotated until it contacts the limit block. At this time, the baffle portion is perpendicular to the first hole. The limit block and the limit bolt cooperate together to prevent the baffle portion from withdrawing from the connecting frame under the action of the elastic pre-tightening force.

[0049] The wire clamp includes:

[0050] A main body frame 14 with a wiring groove 15 penetrating through the front and back;

[0051] A pressing block 16 arranged in the wiring groove 15;

[0052] A screw rod 11 vertically penetrating through the lower part of the main body frame;

[0053] The wiring groove 15 is provided with an opening 17. The lower part of the pressing block 16 is movably connected to the upper end of the screw rod 11. The opening is used to hang the main body frame on the cable. When the screw rod is driven to rotate by a remote control wrench, the pressing block will also move up and down. The higher the pressing block rises, the greater the pressing degree on the cable.

[0054] The upper end of the connecting frame 3 sleeves the lower edge of the main body frame 14. A fastener 22 for connecting the two is provided between the lower end of the connecting frame 3 and the remote control wrench 2. As shown in the figure, the upper end of the connecting frame has a notch, which facilitates the sleeving and separation of the connecting frame from the main body frame. The fastener is a bolt.
