Description

Technical Field

[0001] This utility model relates to the field of cable production technology, and specifically to a cable puller. Background Technology

[0002] Cables generally consist of three parts: a conductor, an insulation layer, and a protective layer. There are typically two types: power cables and control cables. Power cables are mainly used for the transmission and distribution of electrical energy; control cables are mainly used for measurement, protection, and control circuits. For thicker cables, a traction device is needed to pull the cable during the winding process.

[0003] Among them, announcement number CN221226985U discloses a cable puller, including a fixing frame, a transmission unit, and a drive unit. A fixing frame, with several fixing frames disposed on its surface, has several through slots to isolate part of the transmission unit's surface from the outside. Protective plates, with several protective plates disposed between the inner and outer sides of the fixing frame through the through slots, are used to shield and protect the exposed area between the cable and the transmission unit. By setting the fixing frame with through slots on the fixing frame and installing protective plates on the fixing frame, the adjusted protective plates can effectively shield and protect the exposed space between the cable inlet port of the transmission unit and the cable, preventing a large amount of space at the inlet port from being exposed to the outside, thus avoiding the possibility of safety accidents during use and improving the safety of the puller.

[0004] However, in actual use, the positions of the fixed frame and the conveying unit are inconvenient to adjust, which results in a relatively fixed distance between the two sets of conveying units. This makes it impossible to use cables of different diameters and to effectively connect the conveying unit and the cable, thus affecting the equipment's traction effect.

[0005] Therefore, it is necessary to invent a cable puller to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a cable puller to solve the problems in the prior art that it cannot be used with cables of different diameters and cannot effectively connect the transmission unit to the cable, thus affecting the pulling effect of the equipment.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cable puller, comprising an equipment housing, a control panel fixedly connected to the surface of the equipment housing, a control box fixedly connected to the rear side of the equipment housing, and two sets of traction components arranged inside the equipment housing, each traction component including a driving wheel, a driven wheel, a traction belt, a mounting frame, a bidirectional reciprocating cylinder, a fixed frame, and support rollers; first limiting rollers rotatably connected to both the left and right sides of the equipment housing, and support frames fixedly connected to both the left and right ends of the equipment housing, with two sets of second limiting rollers arranged on the upper side of each of the two sets of support frames.

[0008] By adopting the above technical solution, the control panel is used to control the equipment. The cable is clamped between two sets of traction components. The two sets of traction components work together to move the cable. At the same time, the bidirectional reciprocating cylinder drives the upper and lower support rollers to adjust up and down, thereby adjusting the distance between the upper and lower traction belts. This makes it easier to clamp cables of different diameters, thereby moving the cable and pulling it.

[0009] Optionally, the driving wheel and the driven wheel are respectively located on the left and right sides inside the equipment housing. The traction belt is connected to the driving wheel and the driven wheel for transmission. A connecting shaft is fixedly connected to the rear side of both the driving wheel and the driven wheel. The connecting shaft is rotatably connected to the rear wall of the equipment housing.

[0010] By adopting the above technical solution, the driving wheel and the driven wheel work together to drive the traction belt to rotate, thereby pulling the cable.

[0011] Optionally, multiple mounting brackets are fixedly connected to the inner side of the rear side of the equipment housing, located inside the upper and lower sets of traction belts. The bidirectional reciprocating cylinder is fixedly installed inside the mounting bracket. The outer ends of the two sets of piston rods in the bidirectional reciprocating cylinder are fixedly connected to a fixing bracket. Multiple support rollers are rotatably connected to the inner side of the fixing bracket. The support rollers abut against the inner wall of the traction belt.

[0012] By adopting the above technical solution, two sets of piston rods are arranged opposite each other in the bidirectional reciprocating cylinder. When the lower piston rod is pushed out, the upper piston rod retracts inward, and vice versa. This adjusts the distance between the two sets of traction belts.

[0013] Optionally, the rear surface of the equipment housing is fixedly connected with two sets of positioning blocks, and the inner sides of the two sets of positioning blocks are rotatably connected with a drive shaft. The opposite ends of the two sets of drive shafts are fixedly connected with a second bevel gear, and the adjacent ends of the two sets of drive shafts are fixedly connected with a third bevel gear.

[0014] By adopting the above technical solution, the positioning block positions the drive shaft, the second bevel gear, and the third bevel gear, while the drive shaft can rotate inside the positioning block.

[0015] Optionally, the rear end of the internal connecting shaft of both sets of drive wheels is fixedly connected to a first bevel gear, and the first bevel gear meshes with the second bevel gear.

[0016] By adopting the above technical solution, the rotation of the drive shaft, the second bevel gear, and the third bevel gear will drive the first bevel gear to rotate, which in turn will drive the drive wheel to rotate.

[0017] Optionally, a servo motor is fixedly installed at the rear end of the control box, and a fourth bevel gear is fixedly connected to the output end of the servo motor, which meshes with the third bevel gear.

[0018] By adopting the above technical solution, the output end of the servo motor drives the fourth bevel gear, and the fourth bevel gear, in conjunction with the third bevel gear, drives the transmission shaft to rotate.

[0019] Optionally, a limiting groove is provided on the side of the support frame, and two sets of limiting blocks are slidably connected inside the limiting groove, with locking screws threaded inside the limiting blocks.

[0020] By adopting the above technical solution, the limiting block slides back and forth inside the limiting groove.

[0021] Optionally, an installation block is fixedly connected to the inner side of the limiting block, and the lower end of the second limiting roller is rotatably connected to the installation block.

[0022] By adopting the above technical solution, the mounting block is locked inside the support frame, and the nut of the locking screw is locked outside the support frame. Tightening the locking screw locks the position of the mounting block and the limiting block. Conversely, loosening the locking screw allows the position of the mounting block and the limiting block to be adjusted.

[0023] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0024] 1. This utility model clamps the cable between two sets of traction components, while a bidirectional reciprocating cylinder drives the upper and lower support rollers to adjust the distance between the two sets of traction belts. This facilitates clamping and traction of cables of different diameters, effectively improving the adaptability of the equipment. Furthermore, the use of traction belts to pull the cable increases the contact area with the cable surface, effectively improving traction stability. 2. This utility model further improves the stability of cable traction by using first and second limiting rollers at both ends to limit the ends of the cable. Simultaneously, the mounting block, limiting block, and locking screw work together to adjust the distance between the two sets of second limiting rollers, making it suitable for cables of different diameters.

[0034] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0035] This utility model provides, for example Figures 1 to 6 The cable puller shown includes a housing 1, a control panel 11 fixedly connected to the surface of the housing 1, a control box 12 fixedly connected to the rear side of the housing 1, and two sets of traction components 2 arranged inside the housing 1. The traction components 2 include a drive wheel 21, a driven wheel 22, a traction belt 23, a mounting frame 24, a bidirectional reciprocating cylinder 25, a fixing frame 26, and a support roller 27. First limit rollers 3 are rotatably connected to both sides of the housing 1, and support frames 4 are fixedly connected to both ends of the housing 1. Two sets of second limit rollers 44 are arranged on the upper side of the two sets of support frames 4. Limit grooves 41 are opened on the side of the support frames 4. Two sets of limit blocks 42 are slidably connected inside the limit grooves 41. Locking screws 45 are threaded inside the limit blocks 42. Mounting blocks 43 are fixedly connected to the inner side of the limit blocks 42. The lower end of the second limit rollers 44 is rotatably connected to the mounting blocks 43.

[0036] During the cable pulling process, the cable is inserted between the upper and lower sets of traction components 2, and both ends of the cable are respectively locked inside the second limiting rollers 44 on both sides. The second limiting rollers 44 are used to position the cable to prevent the cable from swinging left and right or back and forth. At the same time, the first limiting roller 3 is used to support the cable and reduce the friction of the cable.

[0037] When fixing the cable between the upper and lower traction components 2, first activate the multiple sets of bidirectional reciprocating cylinders 25 on both sides to open the distance between the two traction components 2. Then place the cable between the two traction components 2. After placing the cable, adjust the two traction components 2 so that the two traction components 2 can clamp the cable.

[0038] See Figures 2 to 5 The driving wheel 21 and the driven wheel 22 are respectively located on the left and right sides inside the equipment housing 1. The traction belt 23 is connected to the driving wheel 21 and the driven wheel 22. The rear side of the driving wheel 21 and the driven wheel 22 are fixedly connected to the connecting shaft 13. The connecting shaft 13 is rotatably connected to the rear wall of the equipment housing 1. Multiple sets of mounting brackets 24 are fixedly connected to the inner wall of the rear side of the equipment housing 1 at the position inside the upper and lower sets of traction belts 23. The bidirectional reciprocating cylinder 25 is fixedly installed inside the mounting bracket 24. The outer ends of the two sets of piston rods in the bidirectional reciprocating cylinder 25 are fixedly connected to the fixing bracket 26. Multiple sets of support rollers 27 are rotatably connected to the inner side of the fixing bracket 26. The support rollers 27 abut against the inner wall of the traction belt 23.

[0039] Specifically, during the adjustment of the distance between the two sets of traction components 2, the upper and lower sets of bidirectional reciprocating cylinders 25 are activated respectively. The piston rod in the upper set of bidirectional reciprocating cylinders 25 moves upward, driving the mounting brackets 24 on both sides to move upward, thus lifting the upper traction belt 23 upward. The piston rod in the lower set of bidirectional reciprocating cylinders 25 moves downward, driving the mounting brackets 24 on both sides to move downward, thus lifting the lower traction belt 23 downward. At this time, the surfaces of the two sets of traction belts 23 that are close to each other will shift to both sides, thereby increasing the distance between the two sets of traction belts 23.

[0040] After the cable is placed between the two sets of traction belts 23, the bidirectional reciprocating cylinders 25 on both the upper and lower sides are activated again, so that the traction belts 23 on both the upper and lower sides move inward at the same time, and the cable is clamped and fixed by multiple sets of support rollers 27.

[0041] See Figure 1 , Figure 4 and Figure 7 Two sets of positioning blocks 110 are fixedly connected to the rear surface of the equipment housing 1. The inner sides of the two sets of positioning blocks 110 are rotatably connected to the transmission shafts 16. The opposite ends of the two sets of transmission shafts 16 are fixedly connected to the second bevel gears 15, and the close ends of the two sets of transmission shafts 16 are fixedly connected to the third bevel gears 17. The rear ends of the internal connecting shafts 13 of the two sets of drive wheels 21 are fixedly connected to the first bevel gears 14. The first bevel gears 14 and the second bevel gears 15 are meshed. The rear end of the control housing 12 is fixedly installed with a servo motor 19. The output end of the servo motor 19 is fixedly connected to the fourth bevel gear 18. The fourth bevel gear 18 and the third bevel gear 17 are meshed.

[0042] In addition, during the cable traction process of the traction component 2, the servo motor 19 is started, and the output end of the servo motor 19 drives the fourth bevel gear 18 to rotate. The fourth bevel gear 18 drives the third bevel gear 17 to rotate. The third bevel gear 17 drives the second bevel gear 15 to rotate through the transmission shaft 16. The second bevel gear 15 drives the first bevel gear 14 to rotate. The first bevel gear 14 drives the front drive wheel 21 to rotate through the connecting shaft 13. The drive wheel 21 and the driven wheel 22 cooperate to drive the traction belt 23 to rotate, thereby tractioning the cable.

[0043] Working principle: By clamping the cable between two sets of traction components 2, and simultaneously adjusting the upper and lower support rollers 27 driven by the bidirectional reciprocating cylinder 25, the distance between the upper and lower sets of traction belts 23 is adjusted, thus facilitating the clamping and traction of cables of different diameters, effectively improving the adaptability of the equipment. Furthermore, the traction belts 23 increase the contact area with the cable surface, effectively improving the stability of the traction. At the same time, the first limiting rollers 3 and the second limiting rollers 44 at both ends limit the ends of the cable, further improving the stability of cable traction. In addition, the mounting block 43, the limiting block 42, and the locking screw 45 work together to adjust the distance between the two sets of second limiting rollers 44 to accommodate cables of different diameters.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
