However, it should be indicated that, many details listed in the specification are only for making the reader have a thorough understanding of one or more aspects of the utility model, and even if these specific details are not, the aspects of the utility model can be realized.

[0020] Please refer to Figures 1 to 3 The utility model provides a cable traction equipment, and the technical scheme is as follows:

[0021] Including machine body 1, the machine body 1 inside is equipped with cavity 2, and the machine body 1 middle is equipped with the transverse groove 3 that penetrates the left and right sides of machine body 1, the machine body 1 front side upper end is equipped with control unit 4, the machine body 1 is equipped with two traction units, and two traction units are arranged in opposition, the traction unit includes two shafts 5 that are symmetrically arranged, and every shaft 5 is equipped with roller 6, and two roller 6 are around the traction belt 7, the machine body 1 cavity 2 is equipped with two support plates 8, and every support plate 8 is equipped with two support seats 9, two support seats 9 top are commonly connected with connecting frame 10, and every connecting frame 10 is uniformly arranged and is equipped with a plurality of support rollers 11, two support plates 8 are located between two roller 6, and a plurality of support rollers 11 are pressed against traction belt 7, every support seat 9 is hydraulic support, the machine body 1 is equipped with adjusting assembly.

[0022] The traction belt 7 gradually appears loose phenomenon in long-term use due to the comprehensive influence of multiple factors such as gravity and friction force, and the adjusting assembly is arranged beside the rotating shaft 5 in the machine body 1, which can exert an outward pushing force on the rotating shaft 5 when the traction belt 7 is loose, so that the traction belt 7 is always in a tight state, ensuring the stability of the traction cable and avoiding affecting the accuracy and stability of subsequent metering operations.

[0023] The adjusting assembly includes two connecting plates 12 arranged on the inner side walls of the front and rear ends of the machine body 1, each connecting plate 12 is provided with an adjusting part 13, and the output end of each adjusting part 13 is provided with an arc plate 14, two grooves are symmetrically arranged in the machine body 1, and the rotating shaft 5 is arranged in the grooves, and the rotating shaft 5 is sleeved with a sleeve 15 at both ends, and the machine body 1 is provided with a detection unit.

[0024] The adjusting part 13 can select an electric telescopic rod or a hydraulic rod according to the size of the machine body 1, and the front end is provided with an arc plate 14, and the curvature of the arc plate 14 matches the curvature of the sleeve 15, when the detection unit detects that the traction belt 7 is loose, the adjusting part 13 is started, and the arc plate 14 is driven to abut against the sleeve 15 on the rotating shaft 5, and the rotating shaft 5 is continuously given an outward force in the groove, and since the rotating shaft 5 moves slightly in the groove, the sleeve 15 ensures that the rotating shaft 5 can rotate stably without being affected by the force of the adjusting part 13; the sleeve 15 drives the rotating shaft 5 to move outward continuously, so that the traction belt 7 is continuously tightened, effectively recovering and maintaining the stable friction force between the traction belt 7 and the cable; prevent the cable from deviating, and can move steadily along the preset accurate path, which not only greatly reduces the wear of the cable sheath and prolongs its service life, but also completely eliminates the hidden danger of collision with surrounding equipment parts due to the deviation of the cable position, and ensures the safety of the whole equipment operation.

[0025] The detection unit is an infrared sensor 16, and the shaft centers of each infrared sensor 16 are on the same horizontal plane, and each infrared sensor 16 is arranged at a position 1-2 cm away from the edge of the corresponding roller 6.

[0026] The infrared sensor 16 is flush with the shaft 5 axis, which can accurately capture the subtle state changes of the traction belt 7 near the most critical stress area; when the traction belt 7 shows signs of slight looseness, such as local slight displacement caused by long-term vibration, uneven thickness caused by wear and tear, etc., the infrared sensor 16 can be sensitive to perceive, and the infrared sensor 16 is arranged at a position 1-2 cm away from the edge of the corresponding roller 6, which is a reasonable distance. If the traction belt 7 is loose and exceeds 1-2 cm, there is a high probability of deviation and skidding between the cable and the traction belt 7, which will affect the subsequent operation; because on the same plane, the infrared reflection signal received by the sensor will not be affected by the light refraction and shielding caused by the height difference, ensuring the authenticity and accuracy of the signal feedback.

[0028] Two limiting grooves 19 are symmetrically provided on the traction belt 7; during the process of the cable being in close contact with the traction belt 7 and moving with the traction belt 7, due to the inevitable vibration and shaking during equipment operation, there is a risk of the cable deviating from the preset traction trajectory, the limiting groove 19 can accurately clamp the cable, effectively limiting the displacement of the cable in the transverse direction, so that it always moves along the central axis of the traction belt 7, greatly enhancing the stability of the cable traction process, avoiding scratching and collision with surrounding equipment components due to cable deviation, and ensuring the safe and orderly progress of the entire traction operation.

[0029] A connecting seat 20 is provided at the left port of the horizontal groove 3, and two guide rollers 21 are arranged above and below the connecting seat 20; the connecting seat 20 has a guiding effect, which can quickly correct the positional deviation of the cable entering the machine, so that the cable can be quickly and accurately attached to the traction belt 7; during continuous traction, the guide rollers 21 continuously play a fine adjustment role, ensuring that the cable is always in the optimal traction state and eliminating the waste of time caused by repeated debugging due to positional deviation.

[0030] The above merely is preferred implementation manner of the present application, it should be pointed out, for ordinary skilled person in the technical field, on the premise of not departing from the principle of the present application, can also make several improvements and refinements, these improvements and refinements also should be regarded as the protection scope of the present application.
