DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0037] Example 1

[0038] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, a power cable installation device that is flexible and adaptable to multiple wire diameters includes a support mechanism 40, the support mechanism 40 includes a shell 41 with openings at both ends, two groups of conveying members 42 arranged in the shell 41 and distributed up and down, and an adjusting member 43 that drives the two groups of conveying members 42 to move closer to or away from each other, and an inlet gap 411 is arranged on the side wall of the shell 41 close to the conveying member 42;

[0039] The conveyor 42 includes at least two rollers 421, all of which are connected to the same belt 422, and a clamping gap A is formed between the two belts 422. A motor 423 is provided on one of the rollers 421, and the motor 423 drives the belt 422 to rotate through the roller 421. The two groups of belts 422 rotate in opposite directions. Figure 3 As indicated by the arrow in .

[0040] The adjusting member 43 comprises two base plates 435 corresponding to the two groups of conveying members 42 respectively, the base plate 435 comprises a horizontal plate 4351 and a vertical plate 4352, one end of the horizontal plate 4351 is slidably matched with the housing 41 in the up-down direction, a slide groove is longitudinally provided on the side wall of the housing 41, the end of the horizontal plate 4351 is inserted into the interior of the slide groove and slidably matched with it, a roller 421 provided with a motor 423 is assembled with the vertical plate 4352 through the motor 423, and the remaining rollers 421 are rotatably matched with the vertical plate 4352; threaded holes 4353 penetrating the horizontal plate 4351 and the vertical plate 4352 are provided on the base plate 435, the thread directions of the two groups of threaded holes 4353 are opposite, the two groups of threaded holes 4353 are threadedly matched with the same screw rod 434, the screw rod 434 is rotatably arranged inside the housing 41 and rotatably matched with the housing 41;

[0041] Rotating the screw 434 drives the two substrates 435 to move closer to or farther from each other, which is mainly manifested in that on the basis of the sliding cooperation between one end of the horizontal plate 4351 and the shell 41 in the up and down directions, the screw 434 is rotated in the forward direction, and the two substrates 435 move closer to each other, and the screw 434 is rotated in the reverse direction, and the two substrates 435 move away from each other.

[0042] A method for installing a power cable installation device that is flexible and adaptable to multiple wire diameters comprises the following steps:

[0043] S1. Cable penetration: The cable is passed through the inlet gap 411 in sequence through one end opening of the housing 41, the clamping gap A, and the other end opening of the housing 41;

[0044] S2. Cable fixing: Control the screw 434 to rotate, the screw 434 drives the two sets of conveying members 42 to approach each other through the two base plates 435, and the clamping gap A is reduced to clamp the cable;

[0045] S3 cable transport: a motor 423 is started, the belt 422 is driven to rotate by the roller 421, and the two belts 422 rotating in opposite directions flexibly clamp and transport the cable;

[0046] S4. Cable removal: The motor 423 stops, and the control screw 434 rotates in the opposite direction until the clamping gap A is reset, and the cable is taken out from the clamping gap A and the housing 41 through the inlet gap 411.

[0047] The flexible and multi-diameter power cable installation device in this technical solution can 1. adapt to the movement of the cable within a certain range during the high-position connection and assembly process after the cable is installed, and 2. adapt to the simple installation of the cable during the installation process. When in use, the cable passes through the two openings of the housing 41 and passes through the clamping gap A. The screw 434 rotates through the base plate 435 to drive the two sets of conveying members 42 closer, and the clamping gap A is reduced to clamp the cable. The rotating belt 422 flexibly clamps and transports the cable.

[0048] In the present technical solution, the cable is flexibly clamped by a belt 422 rotating in opposite directions, thereby reducing the possibility of damage during the cable installation process; the belt 422 is movably arranged in the up and down directions, that is, the clamping gap A is adjustable, so that the device can be adapted to the use of a variety of cables with different wire diameters, thereby increasing the scope of application; at the same time, the rotating belt 422 is used to flexibly clamp and convey the cable, and the contact area with the cable is large, thereby reducing the local stress on the cable and ensuring the current transmission performance of the cable.

[0049] In order to improve the convenience of placing the cable into the housing 41 and the clamping gap A, as shown in FIG. Figure 1 , Figure 2As shown, the inlet gap 411 is arranged at the level of the clamping gap A; the cable is placed into the housing 41 and the clamping gap A through the inlet gap 411 .

[0050] To improve the stability of the cable inside the clamping gap A, Figure 2 As shown, the outer ring of the belt 422 is provided with limiting grooves, and the two sets of limiting grooves cooperate to clamp the cable; when the belt 422 clamps and conveys the cable, the cable is located inside the limiting grooves, and the setting of the limiting grooves limits the moving path of the cable to prevent the cable from detaching from the belt 422, thereby improving the stability of the cable position.

[0051] To realize the rotation setting of the screw rod 434, as Figure 2 As shown, the adjusting member 43 also includes a motor 2 431 assembled at the bottom of the shell 41. The motor 2 431 can rotate forward and reverse. The output end of the motor 2 431 passes through one of the horizontal plates 4351 and is connected to a gear 1 432. The gear 1 432 is meshed with a gear 2 433. The gear 2 433 is sleeved on the screw 434.

[0052] The motor 2 431 is started to drive the gear 1 432 to rotate forward or reversely. Since the gear 1 432 is meshed with the gear 2 433 , and the gear 2 433 is sleeved on the screw 434 , the screw 434 is driven to rotate synchronously.

[0053] To prevent the cable from moving to the rear end during transportation and affecting the front end operation of the cable, Figure 2 , Figure 5 As shown, an anti-reversal member 44 is disposed inside the housing 41; the anti-reversal member 44 prevents the roller 421 from reversing, and the cable is clamped by the belt 422, thereby preventing the cable from moving to the rear end.

[0054] The anti-reversal member 44 includes a ratchet 441 arranged on the roller 421, the ratchet 441 is matched with a pawl 442, one end of the pawl 442 is movably sleeved with a sleeve 443, and a spring 444 is arranged between the sleeve 443 and the pawl 442; a mounting hole 4354 is arranged on the cross plate 4351, and the sleeve 443 is assembled inside the mounting hole 4354.

[0055] The motor 423 drives the ratchet 441 to rotate synchronously through the roller 421, and the rotation direction is as follows: Figure 5 As shown by the arrow in the figure, during the rotation of the ratchet 441, the gear teeth on the ratchet 441 push the pawl 442, and the pawl 442 moves upward to squeeze the spring 444. After the gear teeth on the ratchet 441 pass over the pawl 442, under the action of the spring 444, the pawl 442 moves downward to cooperate with the gear teeth to prevent the ratchet 441 from rotating in the opposite direction, thereby preventing the drum 421 from reversing.

[0056] like Figure 1 , Figure 2 As shown, the flexible and multi-diameter power cable installation device also includes a base 10, an electric telescopic rod 20 arranged on the base 10, and a base 30 arranged at the output end of the electric telescopic rod 20. The base 10 is placed on the ground to improve the overall stability of the device. The electric telescopic rod 20 increases the height range supported by the device by increasing or shortening its own length, making it more suitable for cable installation operations.

[0057] During the cable installation process, the cable will bend when the direction of the cable changes. In this embodiment, the cable will bend at the input end and output end of the support mechanism 40. If the cable is bent excessively, it will cause damage to the cable. Therefore, the base 30 and the shell 41 are configured to rotate together. When the front end or rear end of the cable needs to be raised or lowered, the shell 41 rotates under the drive of the cable. Figure 1 The right side of the device is the front end. If the cable needs to be raised at the front end, the housing 41 deflects counterclockwise around the shaft 32 to increase the possibility of the cable being kept in a straight line and avoid damage caused by excessive bending of the cable.

[0058] To realize the rotational cooperation between the base 30 and the housing 41, as shown in FIG. Figure 1 , Figure 2 , Figure 6 As shown, the base 30 is U-shaped as a whole, and the shell 41 is inserted into the interior of the base 30; both ends of the longitudinal section of the base 30 extend inward to form a side plate 31, and the longitudinal section of the base 30 and the shell 41 are rotatably matched through a rotating shaft 32, and a torsion spring 33 is provided on the rotating shaft 32, and both ends of the torsion spring 33 are in contact with the side plate 31.

[0059] When the housing 41 is driven by the cable to rotate, the shaft 32 rotates synchronously, and the torsion spring 33 is squeezed. Figure 6 , mainly manifested in that when the shaft 32 rotates counterclockwise, the left end of the torsion spring 33 is squeezed, and when the shaft 32 rotates clockwise, the right end of the torsion spring 33 is squeezed. When the cable is reset, the torsion spring 33 drives the shell 41 to rotate and reset.

[0060] To improve the stability of the contact between the torsion spring 33 and the side plate 31, as Figure 6 As shown, both ends of the torsion spring 33 are provided with support sections 331 , and the support sections 331 are arranged parallel to the side plate 31 and abut against the side plate 31 .

[0061] At this time, when the rotating shaft 32 rotates counterclockwise or clockwise, both ends of the rotating shaft 32 are subjected to force. At the same time, the supporting section 331 squeezes the side plate 31, increasing the contact area between the torsion spring 33 and the side plate 31, thereby ensuring the stability of the cooperation between the supporting mechanism 40 and the base 30.

[0062] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
