DETAILED DESCRIPTION

[0038] Combined with Figure 1 To Attachment Fig.11 The present application provides a C-type wire clamp installation tool and installation method for live distribution network operations, but this does not limit the present application.

[0039] A C-type wire clamp installation tool for live working on a distribution network comprises a base plate 1, on which a support frame 2 for supporting a C-type wire clamp 26 is convexly provided. A vertical plate 101 and a vertically arranged first arc groove 3 are fixed to opposite ends of the base plate 1, and a second arc groove 4 is slidably provided on the base plate 1. The second arc groove 4 is arranged opposite to the concave portion of the first arc groove 3, and the curvature of the concave portion matches the curvature of the end portion of the C-type wire clamp 26.

[0040] A first push rod 402 is protruded from one end of the second arc groove 4 facing the vertical plate 101, and the end of the first push rod 402 is inserted into the outside of the vertical plate 101. A sixth spring 25 is sleeved on the first push rod 402, and both ends of the sixth spring 25 abut against the second arc groove 4 and the vertical plate 101. The sixth spring 25 pushes the second arc groove 4 to move in the direction of the first arc groove 3. Under the push of the sixth spring 25, the second arc groove 4 and the first arc groove 3 clamp the C-type wire clamp 26 together.

[0041] In order to ensure that the second arc groove 4 does not tilt under the push of the sixth spring 25, the first push rod 402 is connected to the middle part of the back plate of the second arc groove 4. A slide rod 401 is protruded from the bottom of the second arc groove 4 facing the support frame 2, and the slide rod 401 is inserted into the through hole of the base of the support frame 2.

[0042] A first spring 6 is sleeved on the slide bar 401 , and the first spring 6 is located on the side of the support frame 2 away from the second arc groove 4 . A spring seat is provided at the end of the slide bar 401 , and the spring seat abuts against the first spring 6 . The first spring 6 pushes the second arc groove 4 to move toward the first arc groove 3 .

[0043] A handle 5 is provided below the bottom plate 1 , and the handle 5 is provided with an anti-skid groove or a non-skid rubber sleeve.

[0044] In order to quickly clamp the C-shaped wire clamp 26, a guiding arc surface is provided on the top of the second arc-shaped groove 4. By directly pressing down the C-shaped wire clamp 26, the second arc-shaped groove 4 can be pushed backward to complete the clamping of the C-shaped wire clamp 26.

[0045] When threading the C-type wire clamp 26, the movable block 2601 needs to be lifted and the slots of the C-type wire clamp 26 for installing the lead wire 27 and the conductor 28 need to be opened. In order to prevent the operator from contacting the C-type wire clamp 26, the present embodiment completes the above action through a clamping device.

[0046] Depend on Fig.10 as well as Fig.11 As shown, a clamping device is provided on the base plate 1, and the clamping device includes two clamping heads arranged opposite to each other. The clamping heads are located on both sides of the first arc groove 3, and the clamping heads are used to clamp the hinge shaft of the movable block 2601 in the C-type wire clamp 26.

[0047] The clamping device comprises a sliding sleeve 15, which is slidably connected to the bottom plate 1. The clamping head comprises a top head 8, a polygonal rod 10 and a first clamping plate 11 which are coaxially and fixedly connected in sequence.

[0048] The polygonal rod 10 is slidably disposed inside the sliding sleeve 15, the plug 8 and the first clamping plate 11 are located on both sides of the sliding sleeve 15, and a fourth spring 21 is sleeved on the polygonal rod 10, and both ends of the fourth spring 21 are respectively in contact with the sliding sleeve 15 and the plug 8.

[0049] Furthermore, a vertical rod 16 is vertically arranged below the sliding sleeve 15, and the bottom of the vertical rod 16 is passed through to the bottom of the base plate 1. The bottoms of the vertical rods 16 on both sides of the clamping device are commonly connected to a connecting plate 17, and the connecting plate 17 is arranged on one side of the handle 5. When the handle 5 is held, the hand can touch the connecting plate 17.

[0050] The bottom plate 1 has a boss 102 protruding from the end thereof. The boss 102 has a through hole, and the vertical rod 16 slides up and down inside the through hole.

[0051] A card slot 18 is fixed on one side of the vertical rod 16 located above the bottom plate 1, and a pressure plate 1901 is slidably provided inside the card slot 18. A baffle 19 is protruding from the top of the pressure plate 1901. A third spring 20 is provided inside the card slot 18, and the third spring 20 is located below the pressure plate 1901. The baffle 19 is clamped with the first clamping plate 11.

[0052] A vertical through slot is provided on one side of the slot 18, and a part of the pressure plate 1901 is arranged outside the slot 18 through the through slot. Under the pushing action of the third spring 20, the baffle 19 moves up to clamp the first clamping plate 11 to prevent the first clamping plate 11 from moving. The baffle 19 can be a U-shaped plate, which is clamped at the connection between the first clamping plate 11 and the polygonal rod 10.

[0053] A second clamping plate 12 is arranged at an interval at one end of the first clamping plate 11 away from the plug 8, and the two are connected by a shaft, and the second clamping plate 12 is clamped with the baffle 19. Through the arrangement of the two clamping plates, the distance between the plugs 8 on both sides during clamping can be adjusted, thereby adapting to C-type wire clamps 26 of different lengths.

[0054] Since the lead 27 is connected to the C-type clamp 26 by plugging, and the wire 28 is mostly connected to the C-type clamp 26 by hanging, the movable block 2601 at the end of the wire 28 not only needs to be moved up, but also needs to be rotated around the hinge axis to fully open the slot.

[0055] In order to achieve the above purpose, in this embodiment, the bottom of the top head 8 is fixed by the sleeve 7, the sleeve 7 is provided with a second push rod 1301, and the end of the second push rod 1301 is fixed with a push block 13. The second push rod 1301 is sleeved with a second spring 14, and a spring seat is fixed on the side of the second push rod 1301 away from the push block 13, and the second spring 14 is arranged between the spring seat and the sleeve 7.

[0056] A connecting rod 901 is rotatably provided on the top head 8, and a U-shaped plate 9 is fixed to the end of the connecting rod 901. Figure 2 As shown, the U-shaped plate 9 is engaged with the movable block 2601 at the end of the installation wire 28. The push block 13 is located below the connecting rod 901, and overcomes the thrust of the second spring 14 to push the second push rod 1301, so that the push block 13 moves forward along the bottom of the inclined connecting rod 901, and the movable block 2601 is driven upward by the U-shaped plate 9 to fully open the slot for installing the wire 28. After the wire 28 is hung, the push block 13 is moved back to seal the slot.

[0057] In order to facilitate pushing the second push rod 1301, two plug holes 403 are provided at the end of the second arc-shaped groove 4, and a push rod 22 slidably connected thereto is penetrated through the plug hole 403. The push rod 22 is arranged corresponding to the second push rod 1301, and one end of the two push rods 22 located outside the bottom plate 1 is commonly connected to a push plate 23. A fifth spring 24 is sleeved on the push rod 22, and the fifth spring 24 is located between the push plate 23 and the vertical plate 101. After the clamping device is in place, the push plate 23 is pushed, and the push rod 22 overcomes the thrust of the fifth spring 24 and moves forward, pushing the second push rod 1301 to move.

[0058] A C-type wire clamp lead installation method, based on the above-mentioned C-type wire clamp installation tool for live distribution network operation, comprises the following steps:

[0059] S01. Clamp the C-type wire clamp 26 between the first arc groove 3 and the second arc groove 4. The two heads 8 clamp the hinge axis of the movable block 2601 in the C-type wire clamp 26. Hold the handle 5 and push the connecting plate 17 upward with the base of the palm. Lift the movable block 2601 through the clamping device to open the plug interface of the wire 28 of the C-type wire clamp 26.

[0060] S02, hang the C-type wire clamp 26 on the wire 28, insert the lead wire 27 into the corresponding jack, and then tighten the nut 2602 of the C-type wire clamp 26;

[0061] S03 . Pull the first push rod 402 outward to release the clamping of the C-type wire clamp 26 and separate from the C-type wire clamp 26 .

[0062] Before the C-type wire clamp 26 is clamped or when the C-type wire clamp 26 is separated, the first clamping plate 11 is pulled outward to clamp the first clamping plate 11 with the baffle 19 .

[0063] The implementation methods of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above implementation methods, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present application.
