[0002] The power cable clamping device is a specially designed mechanical device. Through its specific structure and materials, it can firmly clamp and stably support the power cable. The device can prevent the cable from shifting, shaking or being damaged due to external force or deadweight, thereby ensuring the normal operation of the power system. The power cable clamping device is usually composed of a clamping mechanism, an adjustment mechanism and a supporting structure. The clamping mechanism is the core part of the device, usually composed of a clamping plate, a spring, a bolt and other components. The clamping mechanism clamps the cable tightly through mechanical force or spring force to ensure that the cable will not loosen or fall off. The adjustment mechanism is used to adjust the position and angle of the clamping mechanism to adapt to different The adjustment mechanism is convenient for operators to make precise adjustments to the cables with the same diameter and different positions. The support structure provides a stable support platform for the entire device and is usually made of solid metal materials. The support structure needs to bear the weight of the cable and the force generated by the clamping mechanism. The working principle of the power cable clamping device is to first install the device at a predetermined position, and adjust the position and angle of the clamping mechanism through the adjustment mechanism to keep the appropriate distance and angle with the cable. Then, operate the clamping mechanism to open it and place the cable between the clamping mechanisms. Subsequently, close the clamping mechanism through mechanical force or spring force to clamp the cable tightly.

[0037] In this embodiment, it is necessary to specifically supplement that the locking push rod 1073 is located on the inner side of the claw reset spring 1072 and passes through the clamp connecting column 1074. When the crescent-shaped claw 1071 is subjected to the extrusion force, it pushes the locking push rod 1073 and squeezes the claw reset spring 1072, so that one end of the locking push rod 1073 pushes other components.

[0038] In a preferred embodiment, the bolt knob clamping element 2 includes a hexagonal rotating bolt 201, the side of the hexagonal rotating bolt 201 is rotatably sleeved with an inner rotating bearing 202, the side of the inner rotating bearing 202 is rotatably sleeved with a cable clamping knob shell 203, two rack passage openings 204 are provided on both sides of the cable clamping knob shell 203, a bolt rotating gear 205 is welded to the bottom of the hexagonal rotating bolt 201, the front and back faces of the bolt rotating gear 205 are meshedly connected with meshing movable racks 206, the back faces of the two meshing movable racks 206 are welded with rack connecting strips 207, and one end of the two rack connecting strips 207 are welded with a clamping connecting cylinder 208.

[0039] In the present embodiment, it should be specifically supplemented that, when the hexagonal rotating bolt 201 is rotated, the bolt rotating gear 205 rotates along with the hexagonal rotating bolt 201 due to the welding relationship, and the two meshing movable racks 206 move toward each other due to the meshing relationship with the bolt rotating gear 205, so that the two clamping connecting cylinders 208 are close to each other, the hexagonal rotating bolt 201 is welded to the inner ring of the inner rotating bearing 202, and the cable clamping knob shell 203 is welded to the outer ring of the inner rotating bearing 202, so that the hexagonal rotating bolt 201 can be rotated without affecting the cable clamping knob shell 203.

The locking square hole 306 is used to clamp the slider pin device 304 to fix it and prevent it from moving. After the cable clamping tool stably clamps the cable, it will not move back due to the elasticity of the cable.

[0042] In a preferred embodiment, the slider pin device 304 includes a clamping base slider 3041, and two internal extrusion blocks 3042 are placed on the inner side of the bottom of the clamping base slider 3041, and an intermediate connecting rod 3044 is welded on one side of the two internal extrusion blocks 3042, and a clamping state lock 3045 is welded on one end of the two intermediate connecting rods 3044, and a pin return spring 3043 is welded on one side of the two clamping state locks 3045, and the bottom of the lock down pressure rod 303 is sleeved with the clamping base slider 3041.

[0043] In this embodiment, it is necessary to specifically supplement that the bottom end of the locking pressure rod 303 is at the top of the inner cavity of the clamping base slider 3041, and a round hole is provided on one side of the internal extrusion block 3042 for the pin reset spring 3043 to pass through and connect the clamping state lock 3045. When the locking pressure rod 303 is squeezed downward, the two internal extrusion blocks 3042 are squeezed apart and the clamping state lock 3045 is pushed to move, so that one end of the clamping state lock 3045 comes out of the clamping base slider 3041 and is fixed by the locking square hole 306.

[0044] In a preferred embodiment, the clamping base steering device 4 includes a clamping base plate 401, the bottom rotating shaft of the clamping base plate 401 is connected to the upper component 402 of the direction fixing device, the bottom rotating shaft of the upper component 402 of the direction fixing device is connected to the cable clamping mounting plate 403, the four corners of the top of the cable clamping mounting plate 403 are threadedly connected with mounting fixing bolts 404, the bottom of the cable clamping mounting plate 403 is sleeved with the lower component 405 of the direction fixing device, and the bottom of the lower component 405 of the direction fixing device is welded with a fitting extrusion bottom film 406.

[0045] In this embodiment, it should be specifically supplemented that the top and bottom of the upper component 402 of the direction fixing device are provided with rotating shafts, which can make the clamping base plate 401 rotate to adjust the direction, and the fitting and extrusion film 406 can be squeezed to make the lower component 405 of the direction fixing device move up and fit the bottom of the upper component 402 of the direction fixing device.

[0046] In a preferred embodiment, the upper component 402 of the direction fixing device includes a direction rotating round pestle 4021, the top rotating shaft of the direction rotating round pestle 4021 is connected to the clamping base plate 401, and three direction stabilizing grooves 4022 are provided on the inner side of the top of the direction rotating round pestle 4021.

[0047] In this embodiment, it should be specifically added that the direction stabilizing groove 4022 is used to lock the latch.

[0048] In a preferred embodiment, the lower component 405 of the direction fixing device includes an oriented cylinder 4051, the top of which is provided with three direction determining pins 4052, the side of which is provided with a bottom release spring 4053, the bottom of which is welded with a fitted extruded bottom film 406, and the top of which is welded with a spring surrounding shell 4054.

[0049] In this embodiment, it should be specifically supplemented that the bottom of the bottom release spring 4053 is welded to the top of the extruded bottom film 406, and the spring surrounding shell 4054 wraps the bottom release spring 4053. When the direction determination pin 4052 is in contact with the direction stabilizing groove 4022, the direction rotating round pestle 4021 is locked by the directional cylinder 4051 and cannot rotate, thereby fixing the direction.

[0050] The working principle of the present invention is as follows: when the moving extrusion plunger 110 is squeezed and moved, the air at one end of the T-shaped extrusion air tube 109 is squeezed to the other end of the T-shaped extrusion air tube 109, and the air at the other end pushes the port extension rod 108 to extend outward, and the rotating wheel fixed arc strip 102 extends forward and backward, which is more conducive to reducing the friction of cable shaking. When the cable is shaking, it directly contacts the anti-wear and damage rotating wheel 104. The contact surface of the anti-wear and damage rotating wheel 104 is a smooth curved surface, which reduces the damage to the cable, and is conducive to solving the problem of the clamp of the existing cable clamping device on the cable. The clamping surface is very small. In actual power system applications, cables often shake and sway. The shaking of the cable causes repeated friction on the clamp, which will wear out the outer skin of the cable for a long time, thereby causing a short circuit problem. When the cable mobile clamping device 1 finishes clamping the cable, the crescent-shaped claw 1071 is squeezed by the cable, pushing the locking push rod 1073 to squeeze the locking push rod 303 downward. When the locking push rod 303 is squeezed downward, the two internal squeezing blocks 3042 are squeezed and separated, and the clamping state lock 3045 is pushed to move, so that the clamping One end of the state lock 3045 is out of the clamping base slider 3041 and is locked in the lock square hole 306 to fix it so that it is fixed and does not move. After the cable clamping tool stably clamps the cable, it will not move back due to the elasticity of the cable. The top and bottom of the upper component 402 of the direction fixing device are provided with a rotating shaft, so that the clamping base plate 401 can be rotated to adjust the direction. The fitting and extrusion bottom film 406 is squeezed to make the lower component 405 of the direction fixing device move up and fit the bottom of the upper component 402 of the direction fixing device. The bottom of the bottom release spring 4053 is welded to the fitting and extrusion bottom film At the top of 406, a spring surrounds the outer shell 4054 and wraps the bottom release spring 4053. When the direction is determined, the latch 4052 fits with the direction stabilizing groove 4022, and the direction rotating round pestle 4021 is locked by the directional cylinder 4051 and cannot rotate, thus fixing the direction. This device realizes the steering effect of the clamping device by installing a steering shaft at the base of the clamping device. When the clamping device is installed on the host object, the steering rod is squeezed and displaced, and the latch is sent into the slot to fix the steering rod, which is beneficial to improving the adaptability of the cable clamping device to cable clamping in different directions.
