Description

Technical Field

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

[0002] When laying cables, it is common to encounter situations where the overall length of the cable is too long or the diameter is too large, making it difficult to place the unlaid end of the cable and coordinate with the laying process, thus affecting the efficiency of cable laying. Traditional traction devices rely on traction belts or simple mechanical structures to hold the cable. In long-distance outdoor operations, the weight of the cable and the friction with the ground will bring huge resistance, which will cause the traction process to shake and slip, affecting the laying efficiency. This is why a cable traction device is needed for traction.

[0003] A search revealed a Chinese patent (publication number CN222159379U). While this patented technology can adapt to cables of different thicknesses, enhancing the applicability and flexibility of the equipment, the device can only slightly change the size of the wire groove using a sliding rod, thus making it unable to pull thicker cables. Therefore, those skilled in the art have provided a cable laying traction device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and propose a cable laying traction device that saves physical labor when moving equipment and can be applied to more cables of different thicknesses.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cable laying traction device, comprising a base plate, a second support plate fixedly connected to the center of the base plate, a first hydraulic cylinder provided at the center of the upper surface of the second support plate, a first support plate provided at the output end of the first hydraulic cylinder, a wire device and a winding reel arranged front and back at the center of the upper surface of the first support plate, the wire device comprising a wire base, the wire base fixedly connected to the upper surface of the first support plate, a roller provided near the wire base between the wire base and the winding reel, a frustum groove opened at the center of the inside of the wire base, a plurality of spring grooves arranged around the inside of the frustum groove, a spring body provided in each of the plurality of spring grooves, a push rod provided on the side of each of the plurality of spring bodies near the center of the circumference of the frustum groove, and a ball rotatably connected on the side of each of the plurality of push rods near the center of the circumference of the frustum groove; With the above technical solution, the cable is placed on the winding reel, and one end of the cable is passed through the truncated cone groove and fixed to the ground. The rollers support the cable as it passes through the groove, and the conductor device guides the cable direction. The base plate is then moved, allowing the winding reel to unwind the cable. The cable can then be wound and pulled for laying. Furthermore, the device automatically adjusts the size of the conductor device according to the cable thickness. When a thicker cable enters the truncated cone groove, its own weight presses against the roller, forcing it to compress the push rod, which in turn compresses the spring body in the spring groove. This adapts to cables of different thicknesses, adjusting the cable exit space and effectively guiding the cable laying direction. This device can accommodate cables of varying thicknesses, enhancing its applicability and flexibility, which is particularly important for projects requiring the laying of cables of different specifications.

[0006] Furthermore, a second hydraulic cylinder is provided at the center of the base plate, the output end of the second hydraulic cylinder is in contact with the lower end surface of the second support plate, and a second rubber pad is fixedly connected to the lower end of the second hydraulic cylinder; With the above technical solution, when it is necessary to lift the equipment, the bottom hydraulic cylinder can be used to lift and traction equipment. When the hydraulic cylinder contacts the ground, the second rubber pad can prevent the equipment from rubbing against the ground.

[0007] Furthermore, a hydraulic rod is provided on the upper side wall of the second hydraulic cylinder, and the hydraulic rod is inclined upward to support the lifting handle. With the above technical solution, when movement is required, the staff can press down on the lifting handle to make the hydraulic rod drive the second hydraulic cylinder to lift the second support plate, thereby raising the traction device.

[0008] Furthermore, short grooves are provided on both sides of the front and rear end faces of the base plate. Rotary rods are rotatably connected inside the four short grooves. Pulleys are fixedly installed on the surfaces of the four rotating rods. The two rotating rods are fixedly connected in the lateral direction. One end of the two rotating rods on one side passes through the two short grooves and leads to one side of the base plate. Worm gears are fixedly connected to the ends of the rods. With the above technical solution, the pulley is built into the base plate when it is not needed.

[0009] The cable laying traction device has a worm at the lower end of each of the two worm gears that meshes with the two worm gears. The outer side of each of the two worm gears has a protrusion. One end of each of the two worm gears passes through the rear inner wall of the two protrusions and extends to the rear end of the protrusion. The rear end of each worm gear is fixedly connected to a screw cap. With the above technical solution, a protrusion is fixed on one longitudinal side of the base plate, and the worm passes through the protrusion. By turning the nut, the worm can rotate, and the worm can drive the worm wheel that meshes with it to rotate. The worm wheel then drives the rotating rod to rotate, and the rotating rod then drives the pulley to rotate until the pulley rotates 90 degrees and goes out of the short groove. At this time, the pulley can be released from the short groove, and the pulley can be easily released.

[0010] Furthermore, a first rubber pad is installed at each of the four opposite corners of the lower end face of the base plate; With the above technical solution, when the moving device is not needed, the staff can retract the pulley. The bottom of the base plate has a first rubber pad and a second rubber pad. The first rubber pad and the second rubber pad prevent the base plate of the traction equipment from rubbing against the ground and wearing out the equipment when the pulley is not in use.

[0011] This utility model has the following beneficial effects: 1. In this utility model, the size of the conductor device can be automatically adjusted according to the thickness of the cable. When a thicker cable is inserted into the truncated cone groove, the weight of the cable itself will press the ball, forcing the ball to compress the push rod, which in turn compresses the spring body in the spring groove, thus adapting to cables of different thicknesses. This not only adjusts the cable outlet space of the conductor device, but also effectively guides the laying direction of the cable. This device can adapt to cables of different thicknesses, enhancing the applicability and flexibility of the equipment. This is especially important for projects that require laying cables of different specifications.

[0012] 2. In this utility model, when movement is required, the worker can press down on the lifting handle to cause the hydraulic rod to drive the second hydraulic cylinder to lift the second support plate, thereby lifting the traction device protrusion and fixing it on the base plate. The worm passes through the protrusion, and by turning the nut, the worm can rotate. At this time, the worm can drive the worm wheel meshing with it to rotate. The worm wheel then drives the rotating rod to rotate, and the rotating rod then drives the pulley to rotate until the pulley rotates 90 degrees and moves out of the short groove. At this time, the pulley can be released from the short groove. This utility model uses a hydraulic device to easily release the pulley. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Reference Figure 1-7 This utility model provides an embodiment of a cable laying traction device, including a base plate 7. The center of the base plate 7 is attached to the upper surface of a second support plate 18. A first hydraulic cylinder 6 is provided at the center of the upper surface of the second support plate 18. A first support plate 5 is provided at the output end of the first hydraulic cylinder 6. A wire guide device 2 and a winding reel 4 are arranged front to back at the center of the upper surface of the first support plate 5. The wire guide device 2 includes a wire base 201, which is fixedly connected to the upper surface of the first support plate 5. The wire base 201 and the winding reel 4 are connected to the upper surface of the first support plate 5. The first support plate 5 is connected. A roller 202 is provided near the wire base 201 in the middle of the wire base 201 and the winding reel 4. A frustum groove 207 is opened in the center of the wire base 201. Multiple spring grooves 206 are arranged around the inside of the frustum groove 207. A spring body 204 is provided in each of the multiple spring grooves 206. A push rod 203 is provided on the side of the multiple spring bodies 204 near the center of the circumference of the frustum groove 207. A ball 205 is rotatably connected to the side of the multiple push rods 203 near the center of the circumference of the frustum groove 207.

[0017] like Figure 1 , 5As shown, the cable is placed on the winding reel 4, and one end of the cable is passed through the frustum groove 207 and fixed to the ground. The roller 202 supports the cable as it passes through the frustum groove 207, and the conductor device 2 guides the direction of the cable. Then, the base plate 7 is moved, and the winding reel 4 can wind out the cable. The cable can then be wound out and pulled, and cable laying can begin. At the same time, the device can automatically adjust the size of the conductor device 2 according to the thickness of the cable. When a thicker cable passes through the frustum groove 207, the cable's own weight will press the ball 205, forcing the ball 205 to compress the push rod 203, causing the push rod 203 to compress the spring body 204 in the spring groove 206, thus adapting to cables of different thicknesses. This allows for adjustment of the cable exit space of the conductor device 2 and effectively guides the laying direction of the cable. This device can adapt to cables of different thicknesses, enhancing the applicability and flexibility of the equipment, which is especially important for projects that require laying cables of different specifications.

[0018] like Figure 1 , 2 As shown in Figures 3 and 4, a hydraulic rod 3 is provided on the upper side wall of the second hydraulic cylinder 17. The hydraulic rod 3 is inclined upward to support the lifting handle 1. Short slots 15 are provided on both sides of the front and rear ends of the base plate 7. Rotary rods 12 are rotatably connected inside the four short slots 15. Pulleys 13 are fixedly installed on the surfaces of the four rotary rods 12 respectively. The two rotary rods 12 are fixedly connected to each other laterally. One end of the two rotary rods 12 on one side passes through the two short slots 15 and leads to one side of the base plate 7. The ends of the two rotary rods 12 are fixedly connected to worm gears 8. Each wheel 8 has a worm 10 at its lower end that meshes with the two worm gears 8. Each worm 10 has a protrusion 9 on its outer side. One end of each worm 10 passes through the rear inner wall of the two protrusions 9 and extends to the rear end of the protrusions 9. Each end is fixedly connected to a screw cap 11. A second hydraulic cylinder 17 is located at the center of the bottom plate 7. The output end of the second hydraulic cylinder 17 is in contact with the lower end face of the second support plate 18. A second rubber pad 16 is fixedly connected to the lower end of the second hydraulic cylinder 17. A first rubber pad 14 is installed at each of the four opposite corners of the lower end face of the bottom plate 7.

[0019] When movement is required, the operator can press down on the lifting handle 1 to cause the hydraulic rod 3 to drive the second hydraulic cylinder 17 to lift the second support plate 18, thereby raising the traction device. A protrusion 9 is fixed to one longitudinal side of the base plate 7. The worm gear 10 passes through the protrusion 9. By turning the cap 11, the worm gear 10 rotates, causing the worm gear 10 to drive the meshing worm wheel 8 to rotate. The worm wheel 8 then drives the rotating rod 12 to rotate, which in turn drives the pulley 13 to rotate until the pulley 13 rotates 90 degrees and exits the short groove. At this point, the pulley 13 can be released from the short groove 15, allowing for easy release. When the device is not in use, the operator can retract the pulley 13. The bottom of the base plate 7 has a first rubber pad 14 and a second rubber pad 16, which prevent the base plate 7 from rubbing against the ground. This not only avoids the operator needing to exert effort to lift the traction device when releasing the pulley 13, but also prevents the base plate 7 of the traction device from rubbing against the ground and causing wear when the pulley 13 is not in use.

[0020] Working principle: In use, the cable is placed on the winding reel 4, and one end of the cable is passed through the frustum groove 207 and fixed to the ground. The roller 202 supports the cable as it passes through the frustum groove 207, and the conductor device 2 guides the direction of the cable. Then, the base plate 7 is moved, and the winding reel 4 can wind out the cable. The cable can then be wound and pulled for cable laying. At the same time, the device can automatically adjust the size of the conductor device 2 according to the thickness of the cable. When a thicker cable passes through the frustum groove 207, the cable's own weight will press the ball 205, forcing the ball 205 to compress the push rod 203, causing the push rod 203 to compress the spring body 204 in the spring groove 206. This adapts to cables of different thicknesses, thus adjusting the exit space of the conductor device 2 and effectively guiding the laying direction of the cable. This device can adapt to cables of different thicknesses, enhancing the applicability and flexibility of the equipment, which is especially important for projects that require laying cables of different specifications.

[0021] In use, the device can be easily moved via pulley 13. When movement is required, the operator can press down on the lifting handle 1 to cause the hydraulic rod 3 to drive the second hydraulic cylinder 17 to lift the second support plate 18, thereby raising the traction device. The boss 9 is fixed on the base plate 7, and the worm 11 passes through the boss 9. By turning the cap 11, the worm 10 is rotated. At this time, the worm 10 can drive the worm wheel 8 meshing with it to rotate. The worm wheel 8 then drives the rotating rod 12 to rotate, and the rotating rod 12 then drives the pulley 13 to rotate until the pulley 13 rotates ninety degrees and exits the short groove. 15. At this point, the pulley 13 can be released from the short groove 15. This utility model utilizes a hydraulic device to easily release the pulley 13. When the device does not need to be moved, the operator can retract the pulley 13. The bottom of the base plate 7 has a first rubber pad 14 and a second rubber pad 16, which can prevent the base plate 7 from rubbing against the ground. This not only avoids the operator having to lift the traction device with great effort when releasing the pulley 13, but also prevents the base plate 7 of the traction device from rubbing against the ground and wearing out the equipment when the pulley is not in use.

[0022] The second hydraulic cylinder 17 is connected to the hydraulic rod 3 through a hydraulic system. The hydraulic pump delivers hydraulic oil to the hydraulic cylinders of the two electric push rods. By controlling the flow and pressure of the hydraulic oil, the pistons of the two hydraulic cylinders move at the same speed and displacement, thereby achieving synchronous operation of the two hydraulic push rods. This is a commonly used technique in the synchronous control of the control system and the hydraulic push rods, which will not be elaborated on here.

[0023] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
