DETAILED DESCRIPTION

[0026] Please refer to Figures 1 to 4 The parallel groove wire clamp installation device includes a mounting body 1 and an installation operating rod 4. The mounting body 1 is provided with a wire clamp pushing assembly 2 and a lead fixing assembly 3 for detachably installing the lead wire 7. The mounting body 1 is provided with at least two wire clamp installation grooves 11 along the axial direction of the lead wire 7. The wire clamp installation groove 11 has an opening on one side of the axial direction of the lead wire 7. The wire clamp pushing assembly 2 is provided with one side of the opening. The wire clamp pushing assembly 2 clamps the parallel groove wire clamp 6 between the wire clamp pushing assembly 2 and the wire clamp installation groove 11. The installation operating rod 4 is connected to the mounting body 1 to lift the parallel groove wire clamp 6 and the lead wire 7 and mount them on the live main line.

[0027] There are two wire clamp installation grooves 11 and two wire clamp pusher assemblies 2, the openings of the two wire clamp installation grooves 11 are arranged in opposite directions, and the two wire clamp pusher assemblies 2 are arranged in opposite directions. Two parallel groove wire clamps 6 can be installed at the same time, and the installation efficiency is high. When the number of parallel groove wire clamps 6 needs to be increased, the number of wire clamp pusher assemblies 2 also increases, and the pushing direction is also the axial direction of the lead wire 7.

[0028] like Figure 5 As shown, the parallel groove wire clamp 6 includes a fixing block 61, an upper clamp plate 62 and a lower clamp plate 63 arranged in sequence from top to bottom, and a bolt 64 passes through the fixing block 61, the upper clamp plate 62 and the lower clamp plate 63 in sequence and is tightened with a nut 65, and a first wire groove 66 for placing the lead wire 7 and a second wire groove 67 for placing the live main line are formed between the upper clamp plate 62 and the lower clamp plate 63. The fixing block 61 is clamped and fixed in the wire clamp installation groove 11. The parallel groove wire clamp 6 is the same as many parallel groove wire clamps 6 on the surface, and its shape is an arc surface. As a result, when the installation mode of the parallel groove wire clamp 6 is set to the horizontal direction, the extrusion block 25 located in the longitudinal direction cannot effectively apply a force to the parallel groove wire clamp 6. Therefore, the wire clamp pushing assembly 2 adopts a longitudinal (i.e., axial direction of the lead wire 7) fixing mode, and the extrusion block 25 applies force on both sides of the longitudinal direction of the parallel groove wire clamp 6, which can be applicable to the installation of parallel groove wire clamps 6 of various shapes.

[0029] like Figure 6 As shown, the mounting body 1 includes a mounting plate 12 and an adjusting plate 13, the wire clamp pushing assembly 2, the lead fixing assembly 3 and the mounting operating rod 4 are all connected to the mounting plate 12, the adjusting plate 13 is connected to the top of the mounting plate 12, the top surface of the adjusting plate 13 is higher than the top surface of the mounting plate 12, and the bottom surface of the adjusting plate 13 is an arc surface to adapt to the arc surface of the parallel groove wire clamp 6. The adjusting plate 13 includes a fixed plate 131 and a movable plate 132, the movable plate 132 and the fixed plate 131 are connected by threaded fasteners to form an H-shaped structure, the H-shaped structure includes two wire clamp mounting grooves 11, the wire clamp pushing assembly 2 and the fixed plate 131 clamp the fixed block 61 of the parallel groove wire clamp 6 longitudinally, and the movable plate 132 and the fixed plate 131 clamp the fixed block 61 of the parallel groove wire clamp 6 transversely. By adjusting the threaded fastener, the lateral length of the wire clamp installation groove 11 can be adjusted to adapt to the lateral length of the fixing block 61; and the advancement of the wire clamp advancement assembly 2 can adjust the longitudinal length of the wire clamp installation groove 11 to adapt to the longitudinal length of the fixing block 61.

[0030] The lead fixing assembly 3 is used to fix the lead 7 in a wire groove of the parallel groove clamp 6. The lead fixing assembly 3 can be various fixing clamps and fixing grooves, such as conventional pressing clamps, spring clamps, and snap-on fixing grooves. In this embodiment, it is a lead pressing clamp. Figure 7As shown, the lead fixing assembly 3 specifically includes a second base 31, a second handle 32, a connecting arm 33, a connecting piece, an upper pressing block 34 and a lower pressing block 35, one end of the connecting arm 33 is axially connected to the second base 31, and the other end is axially connected to the middle axis of the second handle 32; one end of the connecting piece is axially connected to the end axis of the second handle 32, and the other end is axially connected to the second base 31. Specifically, the connecting piece includes a T-shaped clip 36 and a connecting shaft 37, and the end of the connecting shaft 37 is connected to the lower pressing block 35; the T-shaped clip 36 includes a vertically arranged shaft connecting portion and a clamping portion, the clamping portion of the T-shaped clip 36 clamps the connecting shaft 37 and is tightened by a nut, the shaft connecting portion is arranged parallel to the connecting shaft 37, the upper end of the shaft connecting portion is axially connected to the second base 31, and the lower end is axially connected to the second handle 32; the upper pressing block 34 is connected to the mounting body 1, and the upper pressing block 34 and the lower pressing block 35 are pressed together to form a accommodating groove 38 for the lead 7, combined with Figure 4 As shown, the receiving groove 38 and the first line groove 66 are arranged in the same line.

[0031] The function of the lead wire presser is to fix the lead wire 7 of the electric wire or conductor in the first wire groove 66 of the parallel groove clamp 6, and ensure that the lead wire 7 is stably located in the first wire groove 66 of the parallel groove clamp 6 before the wire is paralleled. The lead wire presser can provide a reliable mechanical fixation to prevent the lead wire 7 from falling off or loosening under external force. The lead wire presser is a quick clamp, and its working principle is common knowledge in the art, such as the CH-203 series quick clamps produced by Taiwan Jiagang Company.

[0032] The wire clamp push assembly 2 can be selected as a fast push-pull push rod 24 pusher, the principle of which is common knowledge in the art, such as the LD-304-CM, LD-304-EM, and LD-304-HM fast push-pull push rods 24 sold by Shenzhen Ronghua Electronics Co., Ltd. The two wire clamp push assemblies 2 can move the extrusion block 25 to the two ends of the parallel groove wire clamp 6, thereby limiting the position of the parallel groove wire clamp 6. Figure 8 As shown, the wire clamp pushing assembly 2 includes a first base 21, a first handle 22, a curved arm 23, a push rod 24 and an elastic extrusion block 25. The end of the first handle 22 is connected to the first base 21 axis, one end of the curved arm 23 is connected to the first handle 22 axis, and the other end is connected to the push rod 24 axis. The first base 21 is provided with a through hole, and the push rod 24 is connected to the extrusion block 25 after passing through the through hole; the first handle 22 is swung, and the curved arm 23 drives the push rod 24 to slide in the through hole, so that the extrusion block 25 moves longitudinally to squeeze and limit the parallel groove wire clamp 6. The design of the perforation allows the push rod 24 to move only in the axial direction of the lead 7 to apply force to the parallel groove wire clamp 6 longitudinally.

[0033] The extrusion block 25 can be made of rubber material, specifically polyurethane rubber. The elasticity of the extrusion block 25 is to absorb external pressure or impact force through extrusion deformation and convert it into internal energy, thereby protecting other objects or systems from damage. Specifically, when external pressure is applied to the extrusion block 25, the extrusion block 25 will be extruded and deformed due to its deformable characteristics, dispersing the pressure to various parts of the entire extrusion block 25. Once the external pressure disappears, the extrusion block 25 will restore its original shape and volume through elastic recovery. This process of extrusion deformation and elastic recovery enables the extrusion block 25 to slow down or eliminate the impact of external pressure on the parallel groove clamp 6, thereby protecting it from wear.

[0034] The main body of the extrusion block 25 is in a square shape, and two support blocks 26 are provided at the bottom to form a W-shaped support structure. The push rod 24 drives the two support blocks 26 of the extrusion block 25 to move on the surface of the installation body 1. The provision of the support blocks 26 can reduce the contact area with the installation body 1, thereby reducing the friction between the extrusion block 25 and the installation body 1.

[0035] like Fig. 9 As shown, it also includes a joint operating rod 5, which includes a rod body 51, a motor 52, a battery assembly 53, a quick connector 54 and a sleeve 55. The motor 52 and the battery assembly 53 are installed on the rod body 51 and are electrically connected. The battery assembly 53 provides power to the motor 52 for its normal operation. One end of the quick connector 54 is connected to the output shaft of the motor 52, and the other end is connected to the sleeve 55. The motor 52 is used to provide power to the sleeve 55, and the quick connector 54 is used to quickly connect and disconnect the sleeve 55. The sleeve 55 is matched with the nut 65 of the parallel groove wire clamp 6 in a concave-convex manner, and is used to rotate the bolt 64. The motor 52 drives the sleeve 55 to rotate, driving the nut 65 to rotate to tighten the parallel groove wire clamp 6. The joint operating rod 5 is used to tighten the parallel groove wire clamp 6, and sleeves 55 of different specifications can be connected. The motor 52 can be rotated forward and reversed, which enables the operator to complete the operation of the bolt 64 more easily and quickly, greatly improving the work efficiency.

[0036] The rod body 51 of the joint operating rod 5 and the main body of the installation operating rod 4 are wrapped with an insulating sheath. When the operator uses it, the insulated operating rod can avoid electric shock during installation. The insulating sheath is made of a mixture of basalt fiber and PBO fiber, so that the operating rod has the characteristics of high strength, light weight, good heat resistance and flame retardancy, etc.

[0037] In the specific implementation process, first, fix the parallel groove wire clamp 6 in the wire clamp installation groove 11 of the installation body 1, fix the parallel groove wire clamp 6 through the wire clamp pushing assembly 2, then place the lead 7 in the first wire groove 66 of the parallel groove wire clamp 6, and use the lead fixing assembly 3 to clamp and fix the lead 7; finally, mount the whole on the live main line, and tighten the nut 65 under the parallel groove wire clamp 6 through the joint operating rod 5 to fix the parallel groove wire clamp 6 on the live main line. After the parallel groove wire clamp 6 is installed on the lead 7 and the live main line, the wire clamp pushing assembly 2 and the lead fixing assembly 3 are pushed apart, and the parallel groove wire clamp 6 and the parallel groove wire clamp installation device of the present application can be separated. Specifically, the wire clamp pushing assembly 2 and the lead fixing assembly 3 can be pushed apart by other operating rods, so that the lead 7 is separated from the lead fixing assembly 3, and the wire clamp pushing assembly 2 is separated from the parallel groove wire clamp 6. At this time, the parallel groove wire clamp 6 is separated from the installation body 1 together, and the parallel groove wire clamp 6 and the parallel groove wire clamp installation device of the present application are separated.

[0038] In the above-mentioned parallel groove line clamp installation device, the installation method of the parallel groove line clamp 6 is changed from the existing horizontal extrusion fixing method to the longitudinal fixing method. Since many parallel groove line clamps 6 on the market have an arc-shaped appearance, when the installation method of the parallel groove line clamp 6 is set to horizontal, the extrusion block 25 located in the longitudinal direction cannot effectively apply a force to the parallel groove line clamp 6. By adopting the longitudinal fixing method, the force applied by the extrusion block 25 is located on both sides of the parallel groove line clamp 6 in the longitudinal direction, which can be suitable for the installation of parallel groove line clamps 6 of various shapes; and at least two parallel groove line clamps 6 are installed each time, and the installation efficiency is high.
