[0002] As the capillaries of the power system, the distribution network connects thousands of households and is an important guarantee for the in-depth development of the new power system. Since live line connection operations can connect multiple new loads to the distribution network without disturbing the main lines, the importance of live line connection operations is becoming increasingly prominent.

[0003] In the actual process of connecting the lead wires, the operating efficiency is low. The existing operation requires the cooperation of two people and three operating levers to complete. The operation steps such as the lead wire locking and wire clamp disengagement are cumbersome and the labor cost is high. The function of the tools needs to be improved. The existing tools are cumbersome to remove the wire clamps, the reuse rate of the wire clamps is not high, and they cannot be used with live working robots and have a single function. Summary of the invention

[0004] In order to solve the problems in the related art, the present invention provides an efficient and convenient wire clamp fixing device, which solves the problems of low working efficiency and single tool function.

[0005] In order to solve the above problems, the following technical solutions are provided:

[0006] The present invention discloses an efficient and convenient wire clamp fixing device, comprising a horizontally arranged fixing plate, a horizontally arranged fixing plate, a support plate movably arranged below the fixing plate, and a locking mechanism fixed on the left and right sides of the upper surface of the fixing plate, wherein two clamping mechanisms are movably arranged inside the fixing plate, and the end surfaces of the clamping mechanisms that are away from each other are both provided with a reset mechanism, and a locking mechanism is provided on the side of the reset mechanism that is away from the clamping mechanism;

[0007] A wire clamp is provided between the clamping mechanisms when they are close to each other, a main wire is provided inside the wire clamp, and a lead wire is provided between the openings of the locking mechanisms;

[0008] The top surface of the support plate is fixedly connected with an adjustment mechanism that contacts the bottom side wall of the clamping mechanism, and the front and rear positions of the upper surface of the fixed plate are fixedly connected with 5-7 equally spaced positioning pieces, and the front and rear side walls of the bottom end of the wire clamp are respectively in contact with the side surface of the positioning pieces that are close to each other;

[0009] The upper surface of the support plate is rotatably provided with a rotating column which penetrates the fixing plate upwards, and a screw rod penetrates the interior of the wire clamp, and the top end of the rotating column is clamped with the bottom end of the screw rod.

[0010] In the above scheme, the screw of the wire clamp is accurately placed on the rotating column, so the wire clamp is not easy to fall off during operation. After the operation is completed, the wire clamp is unlocked and can be easily detached. The lead wire is installed on the locking mechanism, and the wire clamp is hung on the main wire. The lead wire and the main wire are fastened together, and finally the wire clamp can be detached through the clamping mechanism. Using this structure, only one operator is needed to complete the work, thereby solving the problem of low operation efficiency and reducing labor cost expenditure. The structure is simple to disassemble the wire clamp and improves the reuse rate, thereby solving the problem of single tool function.

[0011] Preferably, the locking mechanism includes four guide columns that pass through the fixed plate and are located in front and behind the lead wires, a placement plate fixed to the top of the guide columns, and a clamping block that is hinged to one end of the placement plate that is close to each other through an axle pin, and a compression spring is fixed between the bottom end face of the clamping block and the top surface of the placement plate.

[0012] Preferably, the clamping blocks are in the shape of a "7" as a whole, and the end faces of the clamping blocks on one side that are close to each other have a concave arc surface, and the arc surface is in clamping contact with the outer ring surface of the lead; wherein, when the lead is not clamped between the clamping blocks, the distance between the mouths formed between the two clamping blocks is smaller than the diameter of the lead; a supporting block is fixedly connected to the end faces of the placing plates on the side that are away from each other, and the top end faces of the supporting blocks are provided with a first groove for placing and clamping the lead.

[0013] In the above scheme, the lower limit of the lead is fixed by setting the support block. By setting the locking mechanism, the lead is placed on the lead installation position, and the lead can be easily pressed down to be in place, so that the lead can be locked with one press, realizing automatic locking of the lead, ensuring that the lead is transported stably and does not fall off.

[0014] Preferably, the clamping mechanism includes four movable blocks passing through the fixed plate, a bending part fixedly connected to the top of the movable block, and a rotating wheel rotatably connected to the bottom end of the bending part through an axle pin, the outer surface of the rim of the rotating wheel contacts the left and right sides of the adjusting mechanism, the vertical cross-section of the bending part is an inverted "L" shape, and the ends of the bending part close to each other are clamped and contacted with the left and right side walls of the wire clamp.

[0015] In the above scheme, by setting the clamping mechanism, the support plate is pushed upward, and the adjusting mechanism can push the two moving blocks to move backwards, so that the bending part is away from the wire clamp. By cooperating with the resetting mechanism and the locking mechanism, the wire clamp is easily unlocked and can be easily removed.

[0016] Preferably, the reset mechanism includes a connecting rod fixed on the side of the bending portion away from each other, and a reset spring sleeved on the outer ring surface of the connecting rod.

[0018] Preferably, a guide column penetrating the supporting plate is fixedly connected to the left and right sides of the bottom surface of the fixed plate, and one end of the guide column located at the bottom of the supporting plate is fixedly connected to a limiting block, and a spring is sleeved on the outer ring of the guide column, and the top and bottom of the spring are respectively in contact with the bottom of the fixed plate and the top of the supporting plate.

[0019] The reset mechanism includes a connecting rod, and the locking mechanism includes a mounting block. The connecting rod and the mounting block are slidably matched, and the mounting block is hollow. A vertical rod arranged vertically is provided on the mounting block. A spring is provided on the section of the vertical rod extending out from the lower end of the mounting block. A cross rod is connected to the vertical rod. A second groove is provided on the section of the connecting rod between the mounting block and the moving block, and the second groove is adapted to the cross rod.

[0020] In the above scheme, by setting the locking mechanism, when the moving block pushes the reset mechanism to move backward, the cross bar in the locking mechanism is stuck in the second groove, the wire clamp can be detached, and it is convenient to install the wire clamp when it is used next time, which greatly improves the reuse rate.

[0021] The fixed plate has strip-shaped through holes on both the left and right sides for the bending part and the moving block to move left and right.

[0022] Preferably, the left and right end faces of the adjusting mechanism both have inwardly inclined slopes, and the left and right slopes of the adjusting mechanism are respectively in contact with the outer surface of the rotating wheel, so as to expand and clamp the mechanisms and move them away from or towards each other after the adjusting mechanism moves upward.

[0023] In the above scheme, the friction force is reduced and the efficiency of the wire clamp disengagement is improved by setting the rotating wheel.

Secondly, a clearance hole is provided on the fixed plate, so that the screw of the wire clamp is accurately placed on the rotating column. The wire clamp is not easy to fall off during operation, and the wire clamp can be easily unlocked. This structure is used to solve the problem of low operating efficiency, reduce labor cost expenditure, and solve the problem of single tool function. BRIEF DESCRIPTION OF THE DRAWINGS

[0038] An adjusting mechanism 10 is fixedly connected to the top surface of the support plate 2 and contacts the bottom side wall of the clamping mechanism 9, and 5-7 equidistantly arranged positioning pieces 13 are fixedly connected to the front and rear positions of the upper surface of the fixing plate 1, and the front and rear side walls of the bottom end of the wire clamp 3 are respectively in contact with the side surface of the positioning pieces 13 that are close to each other;

[0041] The clamping mechanism 9 includes four moving blocks 901 passing through the fixed plate 1, a bending portion 902 fixedly connected to the top of the moving block 901, and a rotating wheel 903 rotatably connected to the bottom end of the bending portion 902 through an axle pin. The outer surface of the rim of the rotating wheel 903 contacts the left and right sides of the adjusting mechanism 10, the vertical section of the bending portion 902 is an inverted "L" shape, and the ends of the bending portion 902 that are close to each other are clamped and contacted with the left and right side walls of the wire clamp 3.

[0042] The reset mechanism 11 includes a connecting rod 112 fixed on the side away from the bending portion 902, and a reset spring 111 sleeved on the outer ring surface of the connecting rod 112; the locking mechanism 12 includes a mounting block 121 fixed on the outer side wall of the support block 405, and a channel is provided inside the mounting block 121 for the end of the connecting rod 112 away from the bending portion 902 to pass through, a vertical rod 122 passes through the bottom surface of the mounting block 121, and a cylindrical spring is sleeved on the outer ring of the vertical rod 122, and the top end surface of the cylindrical spring contacts the bottom surface of the mounting block 121, and one end of the vertical rod 122 located in the channel inside the mounting block 121 is connected to a cross bar 123, and a second groove 113 coupled to the cross bar 123 is provided on the section of the connecting rod 112 located inside the channel.

[0043] A guide column penetrating the supporting plate 2 is fixedly connected to the left and right sides of the bottom surface of the fixed plate 1, and one end of the guide column located at the bottom of the supporting plate 2 is fixedly connected to a limiting block, and a spring is sleeved on the outer ring of the guide column, and the top and bottom of the spring are in contact with the bottom of the fixed plate 1 and the top of the supporting plate 2 respectively.

[0044] The fixed plate 1 has strip-shaped through holes on both the left and right sides for the bending portion 902 and the moving block 901 to move left and right. The left and right end faces of the adjusting mechanism 10 have inwardly inclined slopes, which are in contact with the outer surface of the rotating wheel 903 respectively, and are used to expand and press the pressing mechanism 9 to move away from or towards each other after the adjusting mechanism 10 moves upward.

[0045] The lower end of the screw rod 8 is fixedly connected to a special-shaped block, the top of the rotating column 7 is provided with a hole for the special-shaped block to be inserted and coupled, the inner middle area of ​​the fixed plate 1 is provided with a clearance hole 6 for the rotating column 7 and the screw rod 8 to pass through, and the bottom surface of the support plate 2 is fixedly connected to a long-handled handle.

[0046] According to the preferred solution provided above, the following is a description of the specific workflow:

[0047] Lift the support plate 2 upward to compress the cylindrical spring on the guide column. The slopes on the left and right sides of the adjustment mechanism 10 will contact the rotating wheel 903 and force the moving block 901 to move away from each other, thereby making the bending parts 902 move away from each other to form a space for the wire clamp 3. After that, after the wire clamp 3 is put on the main conductor, the top special-shaped block of the rotating column 7 is inserted into the bottom special-shaped hole of the screw 8. The screw 8 is driven to rotate by rotating the rotating column 7. Since the bottom feet of the wire clamp 3 are stuck between the positioning pieces 13, the rotation of the screw 8 drives the wire clamp 3 downward and allows the main conductor to contact the lead 5 stuck between the clamping blocks 403, so that the lead 5 is charged.

[0048] The fixed plate 1 and the support plate 2 will move away from each other under the elastic restoring action of the cylindrical spring, and the adjusting mechanism 10 will move downward. The moving block 901 that has lost the expansion of the adjusting mechanism 10 will move closer to each other under the elastic restoring action of the reset spring 111. Since the mounting block 121 has an inverted L-shaped slot in the vertical section, after the vertical rod 122 is pulled up and rotated 90 degrees, the cylindrical spring on the outer ring of the vertical rod 122 forces the vertical rod 122 to move downward as a whole so that the cross bar 123 is stuck in the second groove 113. At the same time, the connecting rod 112 moves closer to each other under the elastic action of the reset spring 111. At this time, the two rods 112 will push the ends of the bending portion 902 that are close to each other to clamp the left and right sides of the bottom foot of the wire clamp 3 to prevent the wire clamp 3 from being displaced during the wiring process.

[0049] After the wiring operation is completed, push the support plate 2 upward again to allow the adjustment mechanism 10 to expand the clamping mechanism 9 and move to both sides. Before that, pull the vertical rod 122 upward and rotate it 90 degrees in the opposite direction to disengage the cross rod 123 and the second groove 113, thereby disengaging the wire clamp 3 from the clamping of the ends of the bent portion 902 that are close to each other on the left and right sides of the base. Then pull the rotating column 7 out of the screw 8 to disengage the rotating column 7 and the screw 8 by relying on the clamping relationship of the special-shaped block. At this time, the wire clamp 3 will be unlocked and disengaged from the device, and the device is pulled downward to disengage the clamping connection between the lead 5 and the clamping block 403, thereby achieving the effect of a single person using the device for wiring operations.
