Description

Technical Field

[0001] This utility model relates to a cable traction mechanism, and more specifically, to a cable traction mechanism that facilitates adjustment of the clamping distance. Background Technology

[0002] A cable traction mechanism is a mechanical device used to pull cables from one end to the other, primarily for the construction and maintenance of railway, power, and communication lines. The internal structure of the cable traction mechanism includes a main frame, motor, speed transmission device, drive unit, and conveyor wheels. The main frame houses the power source, clamping assembly, and cable traction track. The clamping assembly clamps the cable onto the cable traction machine belt, and the power source drives the cable traction track. The clamping force can be adjusted by changing the length of the adjusting screw and the height of the crank assembly, thus enabling the cable conveying operation.

[0003] In existing technologies, cable pulling mechanisms are typically unable to accommodate various cable sizes.

[0004] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a cable traction mechanism that is easy to adjust the clamping distance.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cable traction mechanism with adjustable clamping distance, characterized in that: it includes a main base plate, on which two pressure roller lifting plates are provided; each of the two pressure roller lifting plates is provided with a lifting assembly for lifting the pressure roller lifting plates; each of the two pressure roller lifting plates is provided with a cable feeding synchronous crawler assembly; the cable feeding synchronous crawler assembly includes a conveyor belt tensioner, a synchronous roller drive shaft, a synchronous roller driven shaft, multiple pressure roller shafts, and a synchronous crawler; the pressure roller lifting plates are bolted to a tensioner base; the conveyor belt tensioner is elastically and movably connected to the tensioner base; the synchronous roller drive shaft and the synchronous roller driven shaft are respectively rotatably connected to both ends of the main base plate; the synchronous roller drive shafts of the two cable feeding synchronous crawler assemblies are drivenly connected to the same drive assembly; the multiple pressure roller shafts are arranged in the same straight line; the synchronous crawler is wound around the conveyor belt tensioner, the synchronous roller drive shaft, the synchronous roller driven shaft, and the multiple pressure roller shafts.

[0007] By adopting the above technical solution: the height of the lifting plate of the pressure roller can be easily adjusted through the lifting component, thereby changing the clamping distance. This design allows the cable traction mechanism to adapt to cables of different diameters or with different tension requirements, improving the versatility and flexibility of the mechanism. The setting of the conveyor belt tensioner ensures the stability and tension of the synchronous track for cable delivery, reducing the probability of track breakage while maintaining tension. The setting of the drive component provides a power source for the synchronous pulley drive shaft, enabling the cable traction mechanism to operate efficiently. By adjusting the speed and power of the drive component, the cable traction speed can be controlled.

[0008] The present invention is further configured such that: a lifting plate groove for placing a pressing wheel lifting plate is opened on the surface of the main substrate, and two lifting pressure plates are bolted to both sides of the main substrate.

[0009] The present invention is further configured such that: the lifting assembly includes a connecting plate, a clamping cylinder, and a connecting rod; the connecting plate is fixed to the pressing wheel lifting plate; the clamping cylinder is provided with a clamping cylinder mounting plate fixed to the main base plate; and the two ends of the connecting rod are respectively fixed to the connecting plate and the piston rod of the clamping cylinder.

[0010] The present invention is further configured such that: a spring groove is provided on the side of the conveyor belt tensioner facing the tensioner base, the spring groove passes through the tensioner base, a spring is provided in the spring groove, and a spring pressure plate is bolted to the surface of the tensioner base.

[0011] The present invention is further configured such that: the drive assembly includes a geared motor and a helical gear reducer; the output shaft of the geared motor is connected to the input shaft of the helical gear reducer via a coupling; the helical gear reducer has two output shafts, and the two output shafts are respectively fixed to the synchronous wheel drive shafts of two wire feeding synchronous track assemblies.

[0012] The present invention is further configured such that a support plate is bolted to both ends of the main substrate.

[0013] The present invention is further configured as follows: the cable traction mechanism that facilitates adjustment of clamping distance is characterized in that: two side plates are provided on one side of the main base plate, two side plate support shafts are bolted to each of the two side plates, four side plate support shafts are fixedly connected to the main base plate, and a track protection plate is bolted to the surface of the two side plates.

[0014] The present invention has the following advantages: 1. The height of the clamping wheel lifting plate can be easily adjusted by the clamping cylinder, thereby achieving precise control of the clamping distance.

[0015] 2. The spring design in the conveyor belt tensioner gives it a certain degree of elastic adjustment capability. This can automatically compensate for tension changes in the cable caused by load variations, wear, and other factors during traction, maintaining a stable tension state and preventing the cable from becoming too loose or too tight.

[0016] 3. The bevel gears in a helical gear reducer motor can effectively transmit power to the synchronous pulley drive shaft. This results in a compact structure and space-saving design.

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] like Figures 1 to 5As shown, a cable traction mechanism with adjustable clamping distance includes a main base plate 1. Two clamping wheel lifting plates 2 are mounted on the main base plate 1. Each of the two clamping wheel lifting plates 2 has a lifting assembly on one side for raising and lowering the clamping wheel lifting plates 2. Each clamping wheel lifting plate 2 is equipped with a cable feeding synchronous crawler assembly. The cable feeding synchronous crawler assembly includes a conveyor belt tensioner 4, a synchronous wheel drive shaft 6, a synchronous wheel driven shaft 8, multiple clamping wheel shafts 7, and a synchronous crawler 5. The clamping wheel lifting plates 2 are bolted to a tensioner base 3, and the conveyor belt tensioner 4 is elastically and movably connected to the tensioner base 3. The synchronous wheel drive shaft 6 and the synchronous wheel driven shaft 8 are rotatably connected to both ends of the main base plate 1, respectively. The synchronous wheel drive shafts 6 of the two cable feeding synchronous crawler assemblies are driven by the same drive assembly. The multiple clamping wheel shafts 7 are arranged in a straight line. The synchronous crawler 5 is wound around the conveyor belt tensioner 4, the synchronous wheel drive shaft 6, the synchronous wheel driven shaft 8, and the multiple clamping wheel shafts 7.

[0027] In use, the lifting assembly continuously raises and lowers the two pressing wheel lifting plates to adjust the distance between them. The wire feeding synchronous track 5 is rotatably connected to the synchronous wheel drive shaft, several pressing wheel shafts 7, conveyor belt tensioner 4, and synchronous wheel driven shaft 86. The drive mechanism drives the synchronous wheel drive shaft to rotate, and the synchronous wheel drive shaft drives the pressing wheel shafts 7 and synchronous wheel driven shafts 86 to rotate through the wire feeding synchronous track 5, thereby pulling the cable.

[0028] The height of the lifting plate 2 of the pressure roller can be easily adjusted by the lifting assembly, thereby changing the clamping distance. This design allows the cable traction mechanism to adapt to cables of different diameters or with different tension requirements, improving the versatility and flexibility of the mechanism. The conveyor belt tensioner 4 ensures the stability and tension of the cable delivery synchronous track 5, reducing the probability of track breakage while maintaining tension. The drive assembly provides a power source for the synchronous pulley drive shaft, enabling the cable traction mechanism to operate efficiently. By adjusting the speed and power of the drive assembly, the cable traction speed can be controlled.

[0029] The main base plate 1 has a lifting plate groove 9 for placing the pressure roller lifting plate 2 on its surface, and two lifting pressure plates 10 are bolted to both sides of the main base plate 1.

[0030] The design of the lifting plate groove 9 provides a stable support surface for the main base plate 1, allowing the pressure roller lifting plate 2 to be firmly installed on the main base plate 1 without easily shaking or falling off. This design enhances the stability of the entire mechanism, ensuring safety and reliability during cable pulling.

[0031] The opening of the lifting plate groove 9 allows for precise adjustment of the position of the pressure roller lifting plate 2. By adjusting the lifting assembly, the height of the pressure roller lifting plate 2 can be easily changed, thereby achieving precise control of the clamping distance. The presence of the lifting pressure plate 10 further enhances the positioning stability of the pressure roller lifting plate 2, preventing it from shifting or loosening during operation.

[0032] The lifting assembly includes a connecting plate 11, a clamping cylinder 13, and a connecting rod 12; the connecting plate 11 is fixed to the pressing wheel lifting plate 2; the clamping cylinder 13 is provided with a clamping cylinder mounting plate 14 fixed to the main base plate 1; the two ends of the connecting rod 12 are fixed to the piston rods of the connecting plate 11 and the clamping cylinder 13, respectively.

[0033] The connecting plate 11 is bolted to the pressure wheel lifting plate 2 to ensure that the lifting assembly will not loosen or fall off during operation. The connecting rod 12 allows the clamping cylinder 13 to be precisely positioned in the required location, thereby achieving effective clamping of the pressure wheel lifting plate 2. By adjusting the position of the output shaft of the clamping cylinder 13 within the connecting rod 12, the clamping force and stability can be further fine-tuned. As the main clamping power source, the clamping cylinder 13 has fast, accurate, and stable clamping characteristics. By controlling the input air pressure and output stroke of the clamping cylinder 13, precise control of the clamping force of the pressure wheel lifting plate 2 can be achieved, ensuring stability and safety during cable traction. The mounting plate of the clamping cylinder 13 is bolted to the main base plate 1, making the installation and disassembly of the clamping cylinder 13 more convenient and quick.

[0034] The conveyor belt tensioner 4 has a spring groove 15 on the side facing the tensioner base 3. The spring groove 15 passes through the tensioner base 3, and a spring 16 is installed in the spring groove 15. A spring pressure plate 17 is bolted to the surface of the tensioner base 3.

[0035] The spring 16 provides the conveyor belt tensioner 4 with a certain degree of elastic adjustment capability. During conveyor belt operation, various factors may cause changes in belt tension. The elasticity of the spring 16 can automatically compensate for these tension changes, maintaining a stable tension state and preventing the belt from becoming too loose or too tight. Stable conveyor belt tension and cushioning damping contribute to improved conveying efficiency.

[0036] The drive assembly includes a geared motor 18 and a helical gear reducer housing 19; the output shaft of the geared motor 18 is connected to the input shaft of the helical gear reducer housing 19 via a coupling; the helical gear reducer housing 19 has two output shafts 20, which are respectively fixed to the synchronous pulley drive shafts 6 of the two wire feeding synchronous track assemblies.

[0037] Power is transmitted to the input shaft of the helical gear reducer 19 via a coupling. The input shaft of the helical gear reducer 19 drives the output shaft 20 to rotate, thereby enabling the synchronous pulley drive shaft 6 to rotate and drive the wire feeding synchronous track 5 to work. Four reduction support rods can be set at the four corners of the helical gear reducer 19. The reduction support rods are bolted to the main base plate 1 and the helical gear reducer 19.

[0038] A support plate 21 is bolted to both ends of the main base plate 1; two side plates 22 are provided on one side of the main base plate 1, and two side plate support shafts 23 are bolted to both side plates 22. All four side plate support shafts 23 are fixedly connected to the main base plate 1, and a track protection plate 24 is bolted to the surface of the two side plates 22.

[0039] The side plate 22 support shaft firmly fixes the side plate 22 to the main base plate 1, further enhancing the stability of the mechanism and ensuring the accuracy and stability of cable traction. The design of the track guard plate 24 can effectively protect the cable feeding synchronous track 5 and the cable from damage by the external environment. The track guard plate 24 can also prevent the cable from being accidentally scratched or damaged during traction, which helps to improve the safety of the cable traction mechanism. The bolt connection method makes the installation and disassembly of the support plate 21, side plate 22 and track guard plate 24 more convenient.

After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
