Description

Technical Field

[0001] This utility model belongs to the technical field of cable traction machines, and more specifically, it relates to a wear-resistant cable traction machine. Background Technology

[0002] In the process of modernization, various infrastructure construction and renovation projects are being carried out rapidly, leading to a growing demand for cable laying. From upgrading urban power networks and building communication base stations to laying cables in mountainous and submarine environments, traditional manual pulling methods are inefficient and difficult to implement in special scenarios. Cable pulling machines are construction equipment specifically designed for cable pulling. They mainly rely on motors or engines as power sources, transmitting power to the pulling wheel through gears, chains, and other transmission devices to pull the cable. However, traditional cable pulling machines lack a cutting function, meaning that if cable cutting is required during construction, it can only be done manually using tools such as circular saws and angle grinders. This reduces construction efficiency, poses safety hazards due to manual operation, and results in uneven cuts that affect cable connection quality, increasing project costs and the difficulty of later maintenance. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an anti-wear cable pulling machine, which solves the technical problem that traditional cable pulling machines in the prior art lack a cutting function, resulting in reduced construction efficiency.

[0004] The purpose and effect of this anti-wear cable pulling machine are achieved by the following specific technical means:

[0005] A wear-resistant cable pulling machine includes a main base, on both sides of which are respectively provided a pulley cover and a clamping assembly. Multiple driven shafts and a driving shaft are arranged inside the pulley cover. A motor is provided at one end of the driving shaft. Pulleys are threaded through the driving shaft and the multiple driven shafts, and the pulleys are connected by a belt. A housing is provided on the pulley cover, and a traction assembly is arranged inside the housing. The traction assembly includes multiple traction rollers and traction seats. The traction rollers are threaded through the driven shafts and the multiple traction rollers are connected by a friction belt. The clamping assembly is connected to the main base through multiple sets of sliding optical shafts. A shearing assembly and a lubrication assembly are respectively provided at both ends of the housing, and both the shearing assembly and the lubrication assembly are located on the main base.

[0006] According to a preferred embodiment, the shearing assembly includes a shearing seat and multiple sets of hydraulic cylinders. The shearing seat has an installation groove on one side, and the hydraulic cylinders are fitted into the installation groove. A clamping plate and a fixing plate are provided on one side of the shearing seat. A shearing blade is provided between the clamping plate and the shearing seat. The fixing plate covers the hydraulic cylinders. Connecting strips are provided at the shaft ends of the multiple sets of hydraulic cylinders, and the connecting strips are connected to the shearing blades.

[0007] According to a preferred embodiment, the lubrication assembly includes a clamping box and multiple sets of lubrication boxes. A partition is provided inside the clamping box, and a set of sliding plates and a set of clamping springs are respectively provided on both sides of the partition. A sliding shaft passes through the clamping box, and both the sliding plates and the clamping springs pass through the sliding shaft. A box cover is provided on the clamping box, and a through groove is formed on the box cover. A positioning block is provided on the sliding plate, and the positioning block is engaged in the through groove. The bottom of the lubrication box is connected to the positioning block. A positioning rod is provided inside the lubrication box, and a roller passes through the positioning rod. An end cap is provided on top of the lubrication box, and the end cap covers the lubrication box, storing solid lubricating oil inside.

[0008] According to a preferred embodiment, the clamping assembly includes a clamping seat and clamping wheels. The clamping seat is provided with multiple sets of vertical rods, and the multiple sets of clamping wheels pass through the vertical rods. The clamping seat is provided with a first cover plate.

[0009] According to a preferred embodiment, the clamping assembly is further provided with multiple sets of cylinders. The cylinders are mounted on the main body base via mounting seats, and the cylinder shaft ends are connected to the bottom of the clamping seat in the clamping assembly via connecting blocks.

[0010] According to a preferred embodiment, the traction assembly further includes a second cover plate, the second cover plate having through holes at both ends, a driven shaft passing through the through holes, and the second cover plate being mounted on the traction seat.

[0011] According to a preferred embodiment, a plurality of mounting holes are provided on one side of the traction seat, a support spring is inserted into the mounting hole, a support cylinder is provided at one end of the support spring, a support wheel is provided at one end of the support cylinder, and the support wheel is located inside the friction belt.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. This wear-resistant cable pulling machine is equipped with a shearing assembly at the cable inlet. Its core consists of a shearing seat and multiple hydraulic cylinders. When cable cutting is required, the hydraulic cylinder shaft retracts, pulling the connecting bar towards the cylinder, which in turn moves the shearing blade. The shearing blade is installed between the clamping plate and the shearing seat, ensuring the cable is fixed in position during cutting, preventing wobbling that could affect cutting accuracy, resulting in a smooth and even cut. This provides favorable conditions for subsequent cable connections and improves cable installation efficiency.

[0014] 2. This wear-resistant cable pulling machine is equipped with a lubrication assembly at the cable outlet, including a clamping box and multiple lubrication boxes, providing automatic and continuous lubrication. A spring inside the clamping box holds a roller at one end of the lubrication box tightly against the cable. The cable drives the roller to rotate, and during rotation, the roller evenly applies lubricating oil to the cable surface. This forms a protective film on the cable surface, preventing scratches, abrasions, and other damage caused by friction even under complex traction paths and high-intensity traction operations. This ensures the cable's insulation performance and mechanical strength, guaranteeing its safety during subsequent electrical connections and use. Attached Figure Description

[0022] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.

[0023] Example:

[0024] like Figures 1 to 5 As shown, this utility model provides an anti-wear cable pulling machine, including a main base 11. The main base 11 serves as the foundation component of the entire device, providing stable support for other components. A pulley cover 31 and a clamping assembly are respectively installed on both sides of the main base 11. The pulley cover 31 protects the internal pulleys and houses multiple sets of driven shafts 28 and a drive shaft 29. One end of the drive shaft 29 is connected to a motor 33. After the motor 33 starts, power is transmitted to the drive shaft 29. Pulleys 51 are threaded onto both the drive shaft 29 and the multiple sets of driven shafts 28. Power is transmitted through belts to the pulleys 51 on the drive shaft 29 and the driven shafts 28. The power from the motor 33 sequentially drives the pulleys 51 on the drive shaft 29 and the driven shafts 28 to rotate. A housing 25 is installed above the pulley cover 31, protecting the internal pulling assembly. The pulling assembly includes multiple sets of pulling rollers 24 and a pulling seat 27. The pulling rollers 24 are threaded onto the driven shafts 28, and the multiple sets of pulling rollers 24 are linked by a friction belt 26 to pull the cable. The clamping assembly is connected to the main base 11 via multiple sets of sliding optical shafts 42, allowing the clamping assembly to move along the sliding optical shafts 42. A shearing assembly and a lubrication assembly are respectively arranged at both ends of the housing 25. The shearing assembly is located at the cable inlet for cutting the cable, while the lubrication assembly is located at the cable outlet to apply an oil layer to the cable surface for lubrication.

[0025] like Figure 2 , Figure 5 As shown, the shearing assembly consists of a shearing seat 34 and multiple hydraulic cylinders 35. A mounting groove 46 is formed on one side of the shearing seat 34, allowing the hydraulic cylinders 35 to be inserted into the mounting groove 46 for secure installation. A clamping plate 48 and a fixing plate 36 are provided on one side of the shearing seat 34, and the shearing blade 47 is installed between the clamping plate 48 and the shearing seat 34. Connecting bars 49 are connected to the shaft ends of the multiple hydraulic cylinders 35, and the connecting bars 49 are connected to the shearing blades 47. When it is necessary to cut the cable, the hydraulic cylinders 35 start working; the movement of their shaft ends drives the connecting bars 49, which in turn causes the shearing blades 47 to move accordingly, completing the cable cutting operation. The fixing plate 36 covers the hydraulic cylinders 35, providing some protection and fixation for the hydraulic cylinders 35.

[0026] The lubrication assembly includes a clamping box 14 and multiple lubrication boxes 16. The clamping box 14 has a partition that divides its interior into different spaces. A set of sliding plates 22 and a set of compression springs 21 are arranged on either side of the partition. A sliding shaft 19 passes through the clamping box 14, and the sliding plates 22 and compression springs 21 are both fitted onto the sliding shaft 19, limiting their range of motion. A box cover 15 is located above the clamping box 14, with a through slot. A positioning block is located on the sliding plate 22, which can engage in the through slot to restrict the position of the sliding plate 22. The bottom of the lubrication box 16 is connected to the positioning block on the sliding plate 22. A positioning rod is located inside the lubrication box 16, with a roller 17 passing through it. An end cap 18 is located above the lubrication box 16, covering it. Solid lubricating oil can be stored inside the lubrication box 16; opening the end cap 18 allows for quick addition of solid lubricating oil.

[0027] like Figures 2 to 4 As shown, the clamping assembly consists of a clamping seat 12 and clamping wheels 13. The clamping seat 12 has multiple sets of vertical rods, and multiple sets of clamping wheels 13 are mounted on the vertical rods and can rotate around them. A first cover plate 32 is installed above the clamping seat 12, which provides some protection for the components on the clamping seat 12. During the cable pulling process, the clamping wheels 13 can apply a certain pressure to the cable to ensure that the cable does not easily slip during pulling.

[0028] Below the clamping assembly, multiple sets of cylinders 44 are also provided. The cylinders 44 are fixedly mounted on the main base 11 via mounting seats 43. The shaft end of the cylinder 44 is connected to a connecting block 45, which is connected to the bottom of the clamping seat 12 in the clamping assembly. By controlling the extension and retraction of the shaft end of the cylinder 44, the clamping seat 12 can be moved, thereby adjusting the pressure of the clamping roller 13 on the cable to adapt to the traction requirements of cables of different specifications and materials.

[0029] The traction assembly also includes a second cover plate 23, which has through holes at both ends. The driven shaft 28 passes through the through holes, allowing the second cover plate 23 to be mounted on the traction seat 27. The second cover plate 23 protects the components in the traction assembly and also helps maintain the structural stability of the traction assembly, ensuring that components such as the traction roller 24 can operate normally during operation.

[0030] The traction seat 27 has multiple sets of mounting holes 37 on one side, and a support spring 38 is inserted into each mounting hole 37. One end of the support spring 38 is connected to a support cylinder 39, and a support wheel 41 is mounted on one end of the support cylinder 39. The support wheel 41 is located inside the friction belt 26. During equipment operation, the support spring 38 can extend and retract according to the force on the friction belt 26, driving the support cylinder 39 and the support wheel 41 to support the friction belt 26. This ensures that the friction belt 26 maintains appropriate tension when driving the traction roller 24 to rotate, thus ensuring the smooth operation of cable traction.

[0031] The specific usage and function of this embodiment are as follows:

[0032] When using the anti-wear cable pulling machine, first place the equipment on a stable surface and connect the power supply to the motor 33. Feed the cable to be pulled in from the inlet end. When it passes through the clamping assembly, control the extension and retraction of the shaft end of the cylinder 44 to drive the clamping seat 12 to move, so that the clamping wheel 13 applies appropriate pressure to the cable to prevent the cable from slipping during the pulling process.

[0033] The motor 33 is started, and power is transmitted through the drive shaft 29, driving the pulley 51 and belt to rotate, which in turn causes the driven shaft 28 to rotate. The traction rollers 24, which are mounted on the driven shaft 28, also rotate accordingly. Multiple sets of traction rollers 24 are linked together by the friction belt 26, and the cable moves forward under the drive of the traction rollers 24. During the traction process, the lubrication components at the cable outlet start to work. The slide plate 22 inside the clamping box 14 moves under the action of the clamping spring 21, driving the lubrication box 16. The roller 17 is pressed tightly against the cable under the spring pressure. The cable drives the roller 17 to rotate, spreading lubricating oil evenly on the surface of the cable, reducing the coefficient of friction and reducing cable wear.

[0034] When the cable is pulled to the required length, the hydraulic cylinder 35 retracts, pulling the connecting strip 49 and causing the shearing blade 47 to move. The clamping plate 48 and the shearing seat 34 fix the cable, completing the cutting operation. The cut is clean, facilitating subsequent connections. Throughout the process, the second cover plate 23 and the first cover plate 32 protect the components of the traction assembly and the clamping assembly, respectively. The support spring 38, support cylinder 39, and support wheel 41 on one side of the traction seat 27 are adjusted according to the force on the friction belt 26 to ensure the tension of the friction belt 26 and ensure smooth cable traction.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
