Description

Technical Field

[0001] This utility model belongs to the field of power cable laying technology, and in particular relates to a traction device for power cable laying. Background Technology

[0002] As the arteries of modern urban energy transmission, the quality of power cable installation directly affects the reliability and safety of the power grid. With the acceleration of urbanization, underground cable laying has become the mainstream method, avoiding the impact of overhead lines on the cityscape and reducing the risk of failures caused by extreme weather. This necessitates specialized traction equipment, which can solve problems such as insufficient bending radius and insulation wear caused by the cable's own weight in traditional manual laying.

[0003] Comparing this to Chinese patent CN120049334A, a power cable anti-retraction laying device is disclosed. This device includes a cable reel, a movable support, a rotating shaft, a limiting component, an anti-retraction component, and a traction mechanism. Two movable supports are provided, each equipped with casters at its bottom. The rotating shaft is rotatably connected to the movable supports. The cable reel is detachably mounted between the two rotating shafts. The limiting component limits the movable supports, and the anti-retraction component restricts unidirectional rotation of the rotating shaft. The anti-retraction component includes a ratchet, a fixing block, and a pawl. The ratchet is coaxially fixedly fitted onto the outside of the rotating shaft. The fixing block is connected to the movable support, and the pawl is rotatably connected to the movable support. The pawl is connected to the fixing block via a stop spring, and the pawl contacts the ratchet teeth on the ratchet. The traction mechanism is used to pull the power cable. This device solves the problem of cable retraction or elongation during laying, which affects the accuracy of the laying process in existing technologies.

[0004] However, the aforementioned patent requires manual lifting of heavy cable reels, which poses safety risks and high-intensity labor problems, and increases the difficulty of operation, making it time-consuming and labor-intensive. Therefore, a new device needs to be designed. Utility Model Content

[0005] The purpose of this utility model is to provide a traction device for laying power cables to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A traction device for laying power cables includes a wire-feeding roller and a chassis for traction movement. The chassis is equipped with a support device for vertically moving and rotating the wire-feeding roller. One end of the support device is fitted with a wire-feeding device for clamping and actively releasing the cable. The wire-feeding roller is rotatably mounted on the support device. The chassis includes a movable frame with a traction ring fixedly mounted at one end. A clearance groove is provided in the middle of the movable frame, passing through the end of the movable frame away from the traction ring. The bottom of the movable frame is equipped with a device for electrically stable movement. The moving walking component; the supporting device includes a top bracket, with four electric push rods evenly distributed at the four corners of the bottom of the top bracket, and two suspension components symmetrically arranged below the top bracket for suspending and supporting rotation, with a support shaft placed between the suspension components, and limit baffles symmetrically arranged at both ends of the support shaft, the limit baffles being fixedly connected to the support shaft by locking pins; the wire feeding device includes a cantilever frame, with an active roller installed at the bottom of the cantilever frame, a wire feeding motor arranged on one side of the active roller, a lower pressure roller arranged above the active roller, and a pressure component for elastic pressure application arranged on the lower pressure roller.

[0008] Furthermore, the walking assembly includes four walking motors evenly distributed at the four corners of the bottom of the mobile frame and two symmetrically installed batteries, with walking wheels installed at the output end of each walking motor.

[0009] Furthermore: the walking motor is located on the outer side, and the walking wheel is located on the inner side.

[0010] Furthermore: the suspension assembly includes a suspension bracket, which is L-shaped, and two support wheels are symmetrically installed at the bottom of the suspension bracket.

[0011] Furthermore, a reinforcing rib is provided between the suspension frame and the top support, and the reinforcing rib is triangular.

[0012] Furthermore: the pressurizing assembly includes a lifting frame mounted on the lower pressure roller, a limiting slide rod installed at the top center of the lifting frame, a force-applying spring mounted on the limiting slide rod, and two limiting guide rods symmetrically arranged on both sides of the limiting slide rod, the limiting slide rod and the limiting guide rods being slidably connected to the cantilever frame respectively.

[0013] Furthermore, both the drive roller and the pressure roller are drum-shaped.

[0014] Compared with existing technologies, the beneficial effects are:

[0015] The support device uses an electric push rod to drive the top support to lift and lower, which can smoothly lift the wire-laying roller off the ground, solving the safety risks and high labor intensity problems of manually lifting heavy cable rollers. The entire loading process is smooth and can be completed by only a few people, making it simple and convenient to operate. The entire movement is driven by a walking motor, and the wire-laying motor drives the active roller to pull the cable, realizing the full mechanization of the cable laying process. This avoids the cumbersome process of relying on manpower and large machinery in the traditional method, significantly reducing labor intensity and improving laying efficiency. The unique chassis device design has a clearance groove, which allows the equipment to move to the position of the wire-laying roller for loading. The wire-laying device adopts a structure of active roller and lower pressure roller, and the pressure component provides stable elastic pressure. This "waist drum-shaped" roller, combined with an elastic pressure design, can adapt to cables of different diameters, ensuring that the cables are evenly clamped and preventing slippage or excessive compression damage. The active cable release method matches the cable laying speed with the equipment's movement speed, avoiding cable loosening, tangling, or surface wear caused by passive dragging, thus ensuring the quality and lifespan of the cable laying. It effectively overcomes the shortcomings of traditional cable laying methods, such as low efficiency, high labor intensity, easy cable damage, and poor safety, providing an integrated, automated, safe, and reliable cable laying solution with good practical value and market prospects.

The machine 105 is located on the outside, and the traveling wheels 104 are located on the inside. During loading, the moving frame 101 is first pulled by the traction ring 106 and moved to the front of the wire feeding roller 4 with the support of the traveling wheels 104. Then, the battery 103 supplies power to drive the traveling motor 105 to rotate the traveling wheels 104, which drives the moving frame 101 to move backward, so that the wire feeding roller 4 passes through the clearance groove 102 and enters the area below the top support 202 in the moving frame 101. When laying cables, the moving frame 101 supports the traveling motor 105 to drive the traveling wheels 104 to rotate, which drives the whole frame to move.

[0026] In this embodiment: the supporting device 2 includes a top bracket 202, with four electric push rods 201 evenly distributed at the four corners of the bottom of the top bracket 202. Two suspension assemblies for suspending and supporting rotation are symmetrically arranged below the top bracket 202. A support shaft 205 is placed between the suspension assemblies, and limit baffles 206 are symmetrically arranged at both ends of the support shaft 205. The limit baffles 206 are fixedly connected to the support shaft 205 by locking pins 207. The suspension assembly includes a suspension frame 203, which is L-shaped. Two support wheels 204 are symmetrically installed at the bottom of the suspension frame 203. A reinforcing rib 208 is provided between the top support 202 and the cable laying roller 4.

The limiting slide rod 306 supports the force application spring 307 to drive the lower pressure roller 304 to move down through the elastic lower lifting frame 305, pressing the cable tightly on the active roller 303. The limiting guide rod 308 ensures the direction of the up and down movement of the lifting frame 305. When laying the cable, the cantilever frame 301 supports the active roller 303 to rotate and pull the cable to release and lay it.

[0028] Working principle: During loading, the traction ring 106 first pulls the moving frame 101 to move in front of the wire feeding roller 4 under the support of the traveling wheels 104. The support shaft 205 passes through the middle of the wire feeding roller 4, and the locking pin 207 is tightened to fix the limit baffle 206 to the end of the support shaft 205. Then, the battery 103 supplies power to drive the traveling motor 105 to rotate the traveling wheels 104, which drives the moving frame 101 to move backward, so that the wire feeding roller 4 passes through the clearance groove 102 and enters the area below the top support 202 in the moving frame 101. Then, the electric push rod... 201 extends and pushes the top support 202 to drive the suspension frame 203 to rise, so that the four support wheels 204 support the two ends of the support shaft 205 respectively, lifting the wire feeding roller 4 off the ground. Then the cable is pulled out from the wire feeding roller 4 and passes between the active roller 303 and the lower pressure roller 304 on the cantilever frame 301.

The limiting guide rod 308 ensures the direction of the lifting frame 305 to move up and down.

[0029] During cable laying, the mobile frame 101 supports the walking motor 105 to drive the walking wheel 104 to rotate, thus moving the whole structure. At the same time, the cantilever frame 301 supports the active roller 303 to rotate and pull the cable to release and lay it. The cable laying roller 4, supported by the support shaft 205, rotates and releases the cable through the support roller 204, thus completing the cable laying.
