Description

Technical Field

[0001] This application belongs to the field of cable processing technology, specifically relating to a cable reel storage vehicle for power supply. Background Technology

[0002] Cable reels are specialized reels for electrical wires and cables. They are typically constructed of steel or steel-wood. Steel structures are sturdy, durable, provide good cable protection, and are reusable, making them widely used in practice. Power cables are generally transported, stored, and laid while wound on cable reels. Short cables under 30m can also be wrapped into loops and securely bundled before transport, ensuring the wrapping is within the cable's minimum allowable bending radius.

[0003] After the cable reel is wound with the cable, it can generally be transported to the installation location using vehicles such as trucks. However, for particularly heavy cable reels, due to their large weight, hoisting is usually used for transportation. To facilitate hoisting, the two discs on both sides of the cable reel are typically placed in contact with the ground. While this placement method facilitates hoisting, after placement, the hoisting machine is not on-site, and the weight of the cable reel makes it inconvenient to move or adjust its position again. If further movement is required, a crane must be used again, causing inconvenience in actual use. Summary of the Invention

[0004] This application provides a power supply cable reel storage vehicle to solve the above-mentioned technical problems.

[0005] The technical solution adopted in this application is as follows: A cable reel storage vehicle for power supply includes a base with an installation space inside. A rotating assembly is fixedly installed in the installation space. A turntable is rotatably installed at the top of the base. The rotating assembly includes a pawl, a gear ring, and a worm gear meshing with the gear ring. Positioning grooves are divided around the inner side of the gear ring. The pawl is coaxial with the gear ring and engages with the positioning grooves. One end of the worm gear passes through the side wall of the base and is rotatably connected to the drive shaft of a first motor. The gear ring is fixedly connected to the turntable. Multiple hinge seats are evenly distributed on the outer edge of the turntable. The hinge seats are hinged to several rotating arms via hinges. A bracket is provided at the end of each rotating arm. The bracket and the rotating arm are connected by a snap-fit ​​assembly. The snap-fit ​​assembly passes through the snap-fit ​​groove at the end of the bracket and the rotating arm. A lead screw is vertically installed on the base. A movable nut is provided on the lead screw. The movable nut is connected to several connecting rods. The lower end of each connecting rod is connected to the bracket. Detachable swivel casters with braking structures are connected to the four corners of the base frame.

[0006] Optionally, a coupling is provided between the worm and the first motor. One end of the coupling is threaded to the end of the worm shaft, and the other end is connected to the first motor via a spline engagement.

[0007] Optionally, the hinge is a pin shaft, which passes through the pin hole between the rotating arm and the hinge seat, and a locking nut is provided on the outside.

[0008] Optionally, the snap-fit ​​assembly includes a sleeve located on one side of the rotating arm, with a wedge-shaped post coaxially arranged inside the sleeve, a return spring sleeved outside the wedge-shaped post, one end of the wedge-shaped post being fixedly connected to the plug block, and the other end being rotatably connected to the handle.

[0009] Optionally, the handle has a protrusion, and the end of the wedge-shaped post facing the handle has a mating groove, with the protrusion mating with the mating groove.

[0010] Optionally, the top of the bracket is symmetrically provided with fixing parts, and placement slots are opened between the fixing parts. A guide surface is opened at the end of the bracket away from the rotating arm.

[0011] Optionally, a second motor is provided on one side of the lead screw. The second motor is rotatably connected to the end of the lead screw shaft through a bevel gear set, and the connecting rod and the moving nut are fixedly hinged.

[0012] Optionally, a mounting ring is fitted onto the upper end of the turntable, and the mounting ring is slidably connected to the turntable. Several hinge seats are equidistantly arranged along the circumference of the mounting ring. Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows: 1. Rotating the lead screw generates linear displacement, and the moving nut moves smoothly on the lead screw. The displacement of the moving nut is transmitted through the connecting rod, enabling the bracket to be raised and lowered vertically without the need for manual lifting or pushing. The number of rotations of the lead screw can accurately position the height of the bracket, adapting to different disc diameters and operating table height requirements. 2. The worm gear meshes with the gear ring to transmit large torque, which can drive the turntable smoothly under heavy load. The pawl automatically engages with the positioning groove inside the gear ring to prevent the turntable from drifting in the opposite direction due to external force or unbalanced load when there is no power. It only allows forward rotation in the direction of movement, thus enhancing the stability of operation. 3. The bracket is equipped with an inclined guide surface to guide the cable reel to slide smoothly into the placement groove, which facilitates alignment. The depth of the placement groove fits tightly with the edge shape of the cable reel. The fixing part clamps the two sides of the reel core, providing double restraint to prevent the reel from tipping over or sliding to the side. 4. The base has a compact internal space layout, with the rotating components integrated with the chassis. Key components (lead screw, gear ring, connecting rod) are made of high-strength alloy steel, and the surface is nitrided or carburized to improve wear resistance and corrosion resistance. Each mechanism (lead screw assembly, bevel gear set, snap-fit ​​assembly) can be disassembled and repaired individually without overall disassembly, reducing maintenance costs and downtime.

[0015] To more clearly illustrate the overall concept of this application, a detailed explanation is provided below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of this application is not limited to the specific embodiments disclosed below. It should be noted that, unless otherwise specified, the embodiments of this application and the features thereof can be combined with each other.

[0017] Example 1: A power cable reel storage vehicle includes a base 1 with an installation space inside. A rotating assembly 2 is fixedly installed within the installation space. A turntable 3 is rotatably mounted on the top of the base 1. The rotating assembly 2 includes a pawl 21, a gear ring 22, and a worm gear 23 that meshes with the gear ring 22. The inner side of the gear ring 22 is divided into positioning grooves. The pawl 21 is coaxially arranged with the gear ring 22 and engages with the positioning grooves. One end of the worm gear 23 passes through the side wall of the base 1 and is rotatably connected to the drive shaft of a first motor 12. The gear ring 22 is fixedly connected to the turntable 3. Multiple hinge seats 4 are evenly distributed on the outer edge of the turntable 3. The hinge seats 4 are hinged to several rotating arms 5 through hinges. The end of the rotating arm 5 is provided with a bracket 6. The bracket 6 and the rotating arm 5 are connected by a snap-fit ​​assembly 7. The snap-fit ​​assembly 7 passes through the snap-fit ​​groove at the end of the bracket 6 and the rotating arm 5. The base 1 is vertically provided with a lead screw 8. The lead screw 8 is provided with a movable nut 9. The movable nut 9 is connected to several connecting rods 10 respectively. The lower end of the connecting rod 10 is connected to the bracket 6. The four corners of the base 1 frame are connected with detachable universal casters 11. The casters are equipped with a braking structure.

[0018] Furthermore, such as Figure 8 , Figure 9 As shown, the snap-fit ​​assembly 7 includes a sleeve 71 located on one side of the rotating arm 5. A wedge-shaped post 72 is coaxially arranged inside the sleeve 71. A return spring 73 is sleeved on the outside of the wedge-shaped post 72. One end of the wedge-shaped post 72 is fixedly connected to the plug block 16, and the other end is rotatably connected to the handle 17.

[0019] Furthermore, such as Figure 9 As shown, the handle 17 has a protrusion 171, and the wedge-shaped post 72 has a mating groove 721 at one end facing the handle 17, and the protrusion 171 mates with the mating groove 721.

[0020] In this embodiment, such as Figure 8 , Figure 9 As shown, in the snap-fit ​​state, the wedge-shaped post 72 is pushed into the slot between the bracket 6 and the rotating arm 5 by the return spring 73, and the insertion block 16 is locked. The protrusion 171 on the handle 17 engages with the mating groove 721 on the wedge-shaped post 72, maintaining the locked state. When disassembly is required, the handle 17 is manually rotated so that the protrusion 171 enters the deepest part of the mating groove 721. Under the retraction action of the return spring 73, the wedge-shaped post 72 drives the insertion block 16 out from between the bracket 6 and the rotating arm 5, achieving quick disassembly to facilitate the replacement of brackets 6 with different diameters and meet more working conditions.

[0021] Furthermore, such as Figure 8 As shown, the top of the bracket 6 is symmetrically provided with fixing parts 61, and placement grooves 62 are opened between the fixing parts 61. A guide surface 63 is opened at the end of the bracket 6 away from the rotating arm 5.

[0022] In this embodiment, such as Figure 1As shown, preferably, the bracket 6, the rotating arm 5, and the connecting rod 10 are arranged in six groups.

[0023] Furthermore, such as Figure 4 , Figure 5 As shown, a second motor 13 is provided on one side of the lead screw 8. The second motor 13 is rotatably connected to the shaft end of the lead screw 8 through a bevel gear set 18. The connecting rod 10 is fixedly hinged to the moving nut 9.

[0024] Furthermore, such as Figure 6 As shown, a mounting ring 19 is fitted on the upper end of the turntable 3. The mounting ring 19 is slidably connected to the turntable 3. Several hinge seats 4 are arranged at equal intervals along the circumference of the mounting ring 19.

[0025] like Figure 1 , Figure 7 As shown, in this embodiment, the connecting rod 10 is a two-arm vertically welded structure, and the connecting rod 10, the rotating arm 5 and the bracket 6 form a rectangular structure.

[0026] When it is necessary to rise, the second motor 13 is started to rotate forward, the bevel gear set 18 drives the lead screw 8 to rotate clockwise, the moving nut 9 moves upward along the lead screw 8, the moving nut 9 moves upward and drives the connecting rod 10 to move, which in turn drives the mounting ring 19 to slide along the axis of the turntable 3, so that the rotating arm 5 is raised synchronously, the bracket 6 moves upward with the rotating arm 5, and the three remain parallel and synchronous until they leave the ground and are retracted.

[0027] like Figure 3 As shown, when the bracket 6 is fully raised, the first motor 12 starts, driving the worm gear 23 to rotate. The worm gear 23 meshes with the gear ring 22, causing the gear ring 22 to rotate, thereby driving the turntable 3 to rotate. At the same time, the pawl 21 engages with the positioning groove inside the gear ring 22 to stop and achieve unidirectional limiting and anti-reverse rotation during the rotation of the turntable 3.

[0028] When placement is required, the second motor 13 is started to reverse, the lead screw 8 rotates counterclockwise, the moving nut 9 moves down along the lead screw 8, and the moving nut 9 moves down to drive the connecting rod 10 and the rotating arm 5 to descend synchronously until the bottom surface of the bracket 6 contacts the ground. Then the cable reel is placed into the placement slot 62 of the bracket 6 along the guide surface 63 and locked by the fixing part 61.

[0029] Example 2 Based on Example 1, such as Figure 2 As shown, in this embodiment, the connecting rod 10 is a single-arm structure, and the movable nut 9 is connected to the connecting rod 10. The connecting rod 10 is inclined in different directions, so that it, together with the rotating arm 5 and the bracket 6, forms a stable triangular support structure.

[0030] The movable nut 9 connects to the inclined connecting rod 10, the lower end of which is connected to the bracket 6, locking the mounting ring 19 to the turntable 3. The hinge seat 4 becomes a fixed fulcrum, and the movement is a lever-type pitch. After the second motor 13 is started, the movable nut 9 descends along the lead screw 8, and the inclined connecting rod 10 is pulled down accordingly, driving the rotating arm 5 to rotate around the pin shaft 14, realizing the downward movement of the bracket 6. When the bracket 6 swings to the ground, the cable reel loading is completed, and the operation is the same as described above. The lifting process is reversed. The second motor 13 reverses, the movable nut 9 drives the connecting rod 10 to rise, and the rotating arm 5 swings back around the pin shaft 14, lifting the bracket 6 and the cable reel.

[0031] This embodiment does not specifically limit the locking method of the mounting ring 19. Preferably, the mounting ring 19 and the turntable 3 are connected by bolts.

[0032] Furthermore, a coupling is provided between the worm 23 and the first motor 12. One end of the coupling is threaded to the shaft end of the worm 23, and the other end is connected to the first motor 12 through a spline engagement.

[0033] Furthermore, such as Figure 5 As shown, the hinge is a pin shaft 14, which passes through the pin hole of the rotating arm 5 and the hinge seat 4, and a locking nut 15 is provided on the outside.

[0034] Working principle: The operator stands to one side of the device, releases the brakes on the swivel casters 11, and confirms that the bracket 6 is in the retracted position. Then, the "Lower" button is pressed, and the second motor 13 begins to rotate forward, driving the bevel gear set 18 to engage and rotate the lead screw 8. The moving nut 9 slides down along the lead screw 8, simultaneously transmitting torque evenly to the rotating arm 5 via the connecting rod 10. The rotating arm 5 gradually rotates downward at the hinge point, and the bracket 6 descends smoothly until its bottom surface lightly touches the ground. The operator holds the cable reel and lifts it to, or uses a crane to hoist, the front end of the guide surface 63, allowing the cable reel to slide along the guide surface 63 into the placement groove 62. The cable reel is pushed into the fixed part 61, and the handle 17 is turned until a "click" is heard, indicating that the wedge-shaped post 72 has automatically inserted, and the bracket 6 and rotating arm 5 are locked.

[0035] Press the "Up" button, the second motor 13 reverses, the lead screw 8 rotates in the opposite direction, the moving nut 9 drives the connecting rod 10 to lift the rotating arm 5, and the bracket 6 drives the cable reel to rise synchronously. When the bracket 6 and the base 1 maintain a certain gap, the lifting ends and it is ready to move or rotate.

[0036] If the bracket 6 needs to be removed, rotate the release handle 17 at the locking assembly 7. The protrusion 171 on the handle 17 disengages from the wedge post 72 mating groove 721. Under the action of the return spring 73, the wedge post 72 retracts inward, and the insertion block 16 exits the slot. The operator can then remove the bracket 6 from the rotating arm 5.
