Technical Field

[0001] This invention relates to the field of power transmission technology, specifically to an adjustable power transmission cable installation device. Background Technology

[0002] As electricity demand gradually increases, the number of cables used for power transmission also gradually increases, and cables need to be installed during the power transmission process.

[0003] During cable installation, cables often pass through walls, making it difficult to lift them to the accurate installation position. Furthermore, when installing cables at heights, it is difficult to insert them into cable protection conduits. To address these issues, this invention proposes an adjustable power transmission cable installation device. Summary of the Invention

[0004] The purpose of this invention is to provide an adjustable power transmission cable installation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an adjustable power transmission cable installation device, comprising:

[0006] Support base, the bottom of which is equipped with a set of casters;

[0007] A movable plate is disposed above a support base. The movable plate is equipped with a clamping mechanism for placing and clamping cables. The clamping mechanism includes a fixed plate disposed at the upper end of the movable plate. An arc-shaped groove is provided at the upper end of the fixed plate. One end of the arc-shaped groove is a cable entry port, and the other end is a cable exit port. The cable enters the arc-shaped groove from the cable entry port and exits from the cable exit port. A cover plate is provided on the upper side of the cable entry port of the arc-shaped groove, and a clamping block is provided on the lower side of the cover plate. The clamping block abuts against the upper outer side of the cable.

[0008] A lifting mechanism is located at the upper center of the support base and is used to drive the movable plate to rise to accommodate the installation height of the cable.

[0009] As a preferred embodiment of the present invention, the movable wheel set is a universal wheel.

[0010] As a preferred embodiment of the present invention, the lifting mechanism includes a vertical plate disposed on the upper end of a support base. The vertical plate is provided with a sliding groove, and a movable block is slidably connected within the sliding groove. A connecting column is provided on the outer wall of the movable block. Two sets of lifting rods are cross-arranged on the connecting column. The two sets of lifting rods are hinged together at their middle portions. Bottom lifting rods are hinged to the lower ends of the two sets of lifting rods respectively. The bottom lifting rods extend downward and are hinged to the bottom of the sliding groove. Top lifting rods are hinged to the top of the two sets of lifting rods respectively. The two sets of top lifting rods are cross-arranged and hinged together. A slider is provided at the top of each lifting rod. A moving groove is provided on the lower side of the movable plate, and the slider is movably engaged with the moving groove.

[0011] As a preferred embodiment of the present invention, a hydraulic cylinder is installed on one side of the vertical plate of the support base. The piston rod of the hydraulic cylinder extends vertically and is connected to the connecting column through a connecting plate.

[0012] As a preferred embodiment of the present invention, the movable plate can be placed on the upper part of the vertical plate, and a rubber layer is provided on the lower side of the movable plate.

[0013] As a preferred technical solution of the present invention, the bottom wall of the arc-shaped groove is inclined downward from the wire insertion port to the wire exit port, and a number of sets of rolling balls are provided on the bottom wall of the arc-shaped groove. A guide ring is provided at the wire exit port of the arc-shaped groove. The cable passes through the wire exit port along the guide ring, so that the lower outer side of the cable is always in rolling contact with the number of sets of rolling balls along the bottom wall of the arc-shaped groove.

[0014] As a preferred technical solution of the present invention, the movable plate is provided with a frame plate on one side of the fixed plate, the frame plate is provided with a horizontal groove, a reciprocating block is slidably connected in the horizontal groove, the reciprocating block is connected to the cover plate, the frame plate is also equipped with a drive motor, the output shaft of the drive motor is connected to a first rotating arm, the first rotating arm is hinged to a second rotating arm, and the second rotating arm is hinged to the reciprocating block.

[0015] As a preferred embodiment of the present invention, a pulley is installed on the lower side of the cover plate, a pad is provided on the fixed plate, a guide groove for the pulley to move is provided on the pad, the abutting block is rotatably connected to the cover plate, and a stop bar is provided on the lower side of the cover plate to restrict the rotation of the abutting block.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: The present invention provides an adjustable power transmission cable installation device, which can be moved by a set of movable wheels at the bottom of the support base. The cable enters the arc-shaped groove from the wire inlet on the movable plate and exits from the wire outlet. The upper and outer sides of the cable are pressed by the clamping block on the lower side of the cover plate, so that the cable is clamped and kept stable on the movable plate. The lifting mechanism drives the movable plate to rise, transporting the cable to the specific height position required for installation, effectively reducing the installation difficulty and making the operation simple and convenient.

[0017] Furthermore, the present invention also has the following advantages:

[0018] 1. The movable plate can be placed on the vertical plate at its lowest position. The rubber layer provides cushioning and protection to prevent damage to the movable plate. When adjusting the installation height of the cable, the hydraulic cylinder works. The piston rod of the hydraulic cylinder drives the connecting column to move upward along the slide groove through the connecting column, which drives the two sets of lifting rods to move upward. The two sets of lifting rods drive the two sets of top lifting rods to move upward, so that the two sets of sliders move closer to each other in the moving groove, which drives the movable plate to be lifted upward to adapt to different cable installation heights.

[0019] 2. After the cable is raised to the highest installation height, one end of the cable at the outlet is aligned with the cable installation tube. The drive motor works, and the output shaft of the drive motor drives the reciprocating block to reciprocate along the transverse groove through the first and second rotating arms. The reciprocating block drives the cover plate to move back and forth along the guide groove through the pulley. When the pressing block moves above the arc groove to the cable opening, the pressing block is pressed against the outer side of the cable with the cable opening as the initial position. When the pressing block moves away from the cable opening above the arc groove, the friction force drives the cable to move along the arc groove, so that the cable passes through the ball bearings on the bottom wall of the arc groove, passes through the guide ring, exits the outlet, and enters the cable installation tube.

[0020] 3. Stop threading the cable into the cable installation tube when the clamping block no longer contacts the outer surface of the cable. As the clamping block moves towards the cable opening above the arc groove, it rotates in the opposite direction due to inertia. The baffle limits the maximum angle of the clamping block, preventing it from contacting the cable when it reaches the top of the cable opening and pushing the cable out of the installation tube. When threading the cable into the installation tube again, the clamping block moves away from the cable opening above the arc groove. This time, it rotates in the opposite direction due to inertia and clamps against the outer surface of the cable again. The friction force drives the cable to move along the arc groove. Through repeated reciprocating motion, the cover plate moves back and forth along the guide groove via pulleys, gradually threading the cable into the installation tube. The operation is simple and convenient, and the work efficiency is high.

[0021] 4. The top of the guide ring has an opening. After the cable is threaded through the cable installation, the control cover moves the clamping block away from the cable threading opening, so that the clamping block does not contact the outer side of the cable. The operator can then move the cable guide ring opening out, allowing the cable to detach from the arc groove, thus completing the installation and separating the installation equipment from the cable.

[0032] Example 1

[0033] This invention provides a technical solution: an adjustable power transmission cable installation device, including a support base 100, a set of movable wheels 110 installed at the bottom of the support base 100, and the set of movable wheels 110 being omnidirectional wheels;

[0034] A movable plate 300 is disposed above the support base 100. The movable plate 300 is provided with a clamping mechanism 400 for placing and clamping cables. The clamping mechanism 400 includes a fixed plate 410 disposed on the upper end of the movable plate 300. An arc-shaped groove 411 is provided on the upper end of the fixed plate 410. One end of the arc-shaped groove 411 is a wire insertion port, and the other end is a wire exit port. The cable enters the arc-shaped groove 411 from the wire insertion port and exits from the wire exit port. A cover plate 420 is provided on the upper side of the arc-shaped groove 411 for the wire insertion port. A pressing block 421 is provided on the lower side of the cover plate 420 for pressing against the upper outer side of the cable.

[0035] The lifting mechanism 200 is located at the upper middle part of the support base 100 and is used to drive the movable plate 300 to rise to adapt to the installation height of the cable.

[0036] Specifically, the installation equipment can be moved by the movable wheel set 110 at the bottom of the support base 100. The cable enters the arc groove 411 from the cable inlet on the movable plate 300 and exits from the cable outlet. The outer side of the cable is pressed by the clamping block 421 on the underside of the cover plate 420, so that the cable is clamped and kept stable on the movable plate 300. The lifting mechanism 200 drives the movable plate 300 to rise, transporting the cable to the specific height position required for installation, effectively reducing the installation difficulty and making the operation simple and convenient.

[0037] Example 2

[0038] Based on Embodiment 1, the lifting mechanism 200 includes a vertical plate 210 disposed on the upper end of the support base 100. The vertical plate 210 is provided with a sliding groove 211. A movable block 220 is slidably connected in the sliding groove 211. A connecting column 221 is provided on the outer wall of the movable block 220. Two sets of lifting rods 230 are arranged crosswise on the connecting column 221. The two sets of lifting rods 230 are hinged together in the middle. Bottom lifting rods 240 are respectively hinged to the lower ends of the two sets of lifting rods 230. The bottom lifting rods 240 extend downward and are hinged to the bottom of the sliding groove 211. Top lifting rods 250 are respectively hinged to the top of the two sets of lifting rods 230. The two sets of top lifting rods 250 are arranged crosswise and hinged together. A slider 251 is provided on the top of the lifting rods. A moving groove is provided on the lower side of the movable plate 300. The slider 251 is movably engaged with the moving groove.

[0039] A hydraulic cylinder 260 is installed on one side of the vertical plate 210 in the support base 100. The piston rod of the hydraulic cylinder 260 extends vertically and is connected to the connecting column 221 through the connecting plate 261.

[0040] The movable plate 300 can be placed on the upper end of the vertical plate 210, and a rubber layer 310 is provided on the lower side of the movable plate 300.

[0041] Specifically, the movable plate 300 can be placed on the vertical plate 210 at its lowest position. The rubber layer 310 provides cushioning and protection to prevent damage to the movable plate 300. When adjusting the installation height of the cable, the hydraulic cylinder 260 operates. The piston rod of the hydraulic cylinder 260 drives the connecting column 221 to move upward along the slide groove 211 through the connecting column 221, which in turn drives the two sets of lifting rods to move upward. The two sets of lifting rods drive the two sets of top lifting rods 250 to move upward, causing the two sets of sliders 251 to move closer to each other in the moving groove, which in turn lifts the movable plate 300 upward to adapt to different cable installation heights.

[0042] Example 3

[0043] Based on Embodiment 1 or Embodiment 2, the bottom wall of the arc-shaped groove 411 is inclined downward from the wire insertion port to the wire exit port, and several sets of rolling balls 413 are provided on the bottom wall of the arc-shaped groove 411. A guide ring 412 is provided at the wire exit port of the arc-shaped groove 411. The cable passes through the wire exit port along the guide ring 412, so that the lower outer side of the cable is always in rolling contact with several sets of rolling balls 413 along the bottom wall of the arc-shaped groove 411 of the rolling balls 413.

[0044] The movable plate 300 has a frame plate 430 on one side of the fixed plate 410. The frame plate 430 has a horizontal groove 431. A reciprocating block 432 slides in the horizontal groove 431. The reciprocating block 432 is connected to the cover plate 420. The frame plate 430 is also equipped with a drive motor 440. The output shaft of the drive motor 440 is connected to a first rotating arm 441. The first rotating arm 441 is hinged to a second rotating arm 442. The second rotating arm 442 is hinged to the reciprocating block 432.

[0045] A pulley 423 is installed on the underside of the cover plate 420. A pad 450 is provided on the fixed plate 410. A guide groove 451 for the pulley 423 to move is provided on the pad 450. The abutment block 421 is rotatably connected to the cover plate 420. A stop bar 422 is provided on the underside of the cover plate 420. The stop bar 422 is used to restrict the rotation of the abutment block 421.

[0046] Specifically, after the cable is raised to the highest installation height, one end of the cable at the outlet is aligned with the cable installation tube. The drive motor 440 operates, and the output shaft of the drive motor 440 drives the reciprocating block 432 to reciprocate along the transverse groove 431 via the first rotating arm 441 and the second rotating arm 442. The reciprocating block 432 drives the cover plate 420 to move back and forth along the guide groove 451 via the pulley 423. When the pressing block 421 moves above the arc groove to the cable insertion port, the pressing block 421 abuts against the outer side of the cable with the cable insertion port as the initial position. As the pressing block 421 moves away from the cable insertion port above the arc groove, the frictional force drives the cable to move along the arc groove, allowing the cable to pass through the ball bearings 413 on the bottom wall of the arc groove, pass through the guide ring 412, exit the cable at the outlet, and enter the cable installation tube. The process stops when the pressing block 421 no longer contacts the outer side of the cable. When the cable is threaded into the cable installation pipe, the clamping block 421 moves towards the cable opening above the arc groove. Under the action of inertia, the clamping block 421 rotates in the opposite direction of movement. The baffle limits the maximum angle of the clamping block 421, so that the clamping block 421 does not come into contact with the cable when it moves to the upper end of the cable opening, thus preventing the cable from being pushed out of the cable installation pipe. When the cable is threaded into the installation pipe again, the clamping block 421 moves away from the cable opening above the arc groove again. At this time, under the action of inertia, the clamping block 421 rotates in the opposite direction of movement and clamps against the outer side of the cable again. The friction force drives the cable to move along the arc groove. The reciprocating block 432 drives the cover plate 420 to move back and forth along the guide groove 451 through the pulley 423, so that the cable is gradually threaded into the cable installation pipe. The operation is simple and convenient, and the work efficiency is high.

[0047] The top of the guide ring 412 has an opening. After the cable is threaded through the cable installation, the control cover 420 moves the clamping block 421 away from the cable threading opening, so that the clamping block 421 does not contact the outer side of the cable. The operator can move the cable guide ring 412 out of the opening, so that the cable is detached from the arc groove, thus completing the installation and separating the installation equipment from the cable.

[0048] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
