[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0024] To change the traditional rigid contact between the traction chain 3 and the cable, a cable traction machine is designed, such as... Figure 1 As shown, the device includes a frame with two sets of conveying components arranged opposite each other. A traction space 1 is formed between the two sets of conveying components, allowing cables to pass through. Each set of conveying components has traction blocks 2 evenly distributed on it. One side of the traction block 2 is fixed to the conveying component by an elastic component, and the other side has a traction groove 21 that contacts the cable. The cable is inserted between the two sets of conveying components. Under the squeezing and friction of the traction chain 3, the cable is subjected to pushing or pulling forces to complete the traction. The elastic component changes the rigid contact between the traction block 2 and the cable into an elastic contact. This not only allows for a tight fit to the cable surface without causing excessive compression, but also allows for adaptive adjustment according to the diameter and shape of the cable, ensuring a uniform distribution of traction force and preventing damage to the cable due to uneven force.

[0025] like Figure 2 As shown, specifically, the conveying assembly includes a traction chain 3 and spur gears 4 disposed at both ends of the traction chain 3. Two sets of traction chains 3 and spur gears 4 are correspondingly arranged to form traction units, which are arranged vertically. The spur gears 4 at both ends of the traction chain 3 are divided into drive wheels and driven wheels. The drive wheels of the two traction units share a common shaft. A drive motor is disposed below the frame, and the output shaft of the drive motor is fixed to the shaft. Compared with traditional bevel gears, spur gears 4 offer better transmission stability and a lower failure rate. The starter motor drives the drive wheels to rotate, which in turn drives the traction chain 3 to pull the cable.

[0026] To ensure stable installation of the traction block 2, positioning plates 31 for installing elastic components are evenly distributed on the traction chains 3 of the two traction units. The positioning plates 31 are corresponding to the links of the traction chain 3, and are located on the side of the traction chain 3 of the two traction units that are far apart from each other. The traction block 2 is fixed to the periphery of the traction chain 3 by bolts.

[0027] The two sets of conveying components are also surrounded by protective shells. To prevent deformation on the side of the traction chain 3 that contacts the cable, a support frame 10 is also provided on the frame. The support frame 10 is located between the drive wheel and the driven wheel. The support frame 10 includes two support rods 11 and several columns. The columns are fixedly installed between the frame and the outer shell. The two support rods 11 are located on the side of the column near the traction space 1 and abut against the rollers of the traction chain 3. An opening is provided on the side of the column near the traction space 1. The support rod 11 is engaged in the opening and abuts against the rollers of the traction chain 3. Due to the pressure of the cable, a pressure away from the traction space 1 is applied to the support rod 11, making it difficult for the support rod 11 engaged in the opening to fall out, thus ensuring support stability and ensuring the traction effect.

[0028] In order to adjust the distance between the two groups of conveying assemblies, the frame comprises a support base 12 and two mounting bases 13 for mounting the two groups of conveying assemblies respectively, the two mounting bases 13 are sleeved on the cross beam 14 slidingly, and the cross beam 14 is fixed above the support base 12 through the stands 15 at both ends of the cross beam 14. The two mounting bases 13 can slide along the cross beam 14.

[0029] The cross beam 14 is provided with two cross beams 14 arranged at the two ends of the conveying assembly respectively, and a connecting plate 16 is arranged between the two cross beams 14, a push rod 17 is arranged on the connecting plate 16, and the movable end of the push rod 17 is connected with the mounting base 13. The two cross beams 14 can stably support the mounting base 13, and the electric push rod 17 can easily realize the adjustment and position locking of the mounting base 13.

[0030] As shown in Figure 3 , the elastic assembly comprises a bottom plate 5 and a spring 6, the bottom plate 5 is fixed on the positioning piece 31 of the upper and lower groups of traction units through bolts, and the traction block 2 is elastically connected with the bottom plate 5 through the spring 6; a guide rod 7 is arranged between the bottom plate 5 and the traction block 2, one end of the guide rod 7 is fixed with the traction block 2, the other end is movably penetrated through the bottom plate 5, and the spring 6 is sleeved on the guide rod 7. The spring 6 provides elastic support for the traction block 2, and the guide rod 7 is arranged to guide the extension and contraction of the spring 6, prevent it from deviating or twisting, and also support the traction block 2.

[0031] As shown in Figure 4 and 5 , in order to further improve the traction effect, a profiling pad 8 is arranged in the middle of the traction groove 21, and a mounting groove for accommodating the profiling pad 8 is arranged in the middle of the traction groove 21; the profiling pad 8 is a self-adjusting air bag, and a supplementary air bag 9 is arranged between the bottom plate 5 and the traction block 2, and the supplementary air bag 9 is communicated with the self-adjusting air bag through a gas conveying pipe arranged in the traction block 2. Among them, the supplementary air bag 9 is a telescopic tubular air bag, and the profiling pad is retracted in the mounting groove in the initial state, when the traction block 2 is moved backward under the pressure of the cable and extrudes the supplementary air bag 9, the gas in the supplementary air bag 9 enters the self-adjusting air bag, that is, the profiling pad 8 expands and abuts against the cable, which can further improve the traction effect.
