The remaining intermediate bevel gears 522 are rotationally connected to the corresponding support frame 2, mobile base 50, or transmission connecting plate 513 via shafts. The transmission ratio of each bevel gear is set according to the actual travel requirements to ensure accurate power transmission. Cable guide 6 The support rod 60 of the cable guide 6 is made of a seamless steel tube with a diameter of 50mm and a height of 800mm. Its bottom end is fixed to the movable carriage 1 via flange bolts, located midway between the support frame 2 and the drive mechanism 4. A guide ring 61, 150mm in diameter and made of cast iron, is fixed to the top of the support rod 60 via a bracket. Several axle seats 62 are evenly distributed on its inner circumference. Rollers 64, 20mm in diameter and 100mm long, are rotatably mounted between adjacent axle seats 62. Ball bearings 63, 15mm in diameter and protruding 5mm from the surface of the axle seats 62, are mounted on the end faces of the axle seats 62 via bearings.

The top cover is removably bolted, and the internal mounting cavity measures 250mm x 180mm x 200mm. The upper and lower conical discs 76, 77 of the input and output conical disc assemblies 71, 72 are both 150mm in diameter, with a 30° taper angle. The transmission belt 73 is made of 0.5mm thick spring steel and 20mm wide. The elastic support 78 at the bottom of the lower conical disc 77 is a resilient telescopic column with a 50mm travel range. Its top end is connected to the lower conical disc 77 via a bearing. A transmission bevel gear 710 is mounted on the top of the disc shaft 79 of the upper conical disc 76, meshing with the intermediate bevel gear 522. Image sensor 74, an MV-CA050-10GM industrial camera, is mounted on the top of guide ring 61 of cable guide 6 via a bracket. Its lens faces the cable on cable roller 3, capturing the cable exit area. A side box is fixed to the side of box body 70. A DLM-10 linear motor is mounted inside. Its drive end is connected to a speed regulating wheel 75 via a wheel frame. The speed regulating wheel 75 has a diameter of 50 mm and is rotatably mounted on the wheel frame. The wheel frame extends through the connecting port into the mounting cavity, contacting the transmission belt 73. Working process Equipment preparation: The construction workers install the cable roller 3 between the side support plates of the support frame 2, open the side support plate through the hinged structure, put in the cable roller 3 and close it; lead one end of the cable out from the cable roller 3, pass it through the guide ring 61 of the cable guide 6 in sequence, and finally connect it to the traction roller of the drive mechanism 4; start the device through the control unit, and brake the movable wheel to lock the device position. Cable traction: The control unit activates the drive mechanism 4, causing the traction roller to rotate and move the cable, completing the cable traction operation. The cable roller 3 rotates synchronously with the cable traction, unwinding the cable. The starting bevel gear 520 rotates with the cable roller 3, transmitting power to the ending bevel gear 521 through the intermediate bevel gear 522, which drives the cylindrical gear 512 to rotate. Follow-up movement: The cylindrical gear 512 moves along the contour of the waist groove 510 under the meshing action of the rack 511, drives the transmission connecting plate 513 to move through the gear shaft, and then drives the movable base 50 to move back and forth along the guide rail. The support frame 2 moves synchronously with the movable base 50, so that the cable lead-out point always remains in a stable position. Speed ​​adjustment: Image sensor 74 captures the cable status in real time and uses the Canny algorithm to analyze the angle between the cable and the axial direction of cable roller 3 in the horizontal plane. If the angle is too large, the control unit determines that the cable pulling state is abnormal and controls the linear motor to drive the speed regulating wheel 75 to move and squeeze the transmission belt 73, changing the contact radius of the transmission belt 73 on the conical disk assembly, thereby adjusting the transmission ratio of the speed regulating box 7 and changing the movement speed of the mobile base 50 until the cable angle returns to the normal range. The operation is completed: after the cable is pulled to the predetermined position, the control unit controls the driving mechanism 4 to stop working, and the construction personnel disconnect the cable connection, completing the pulling operation; if the cable roller 3 needs to be replaced, repeat the above equipment preparation steps. During the entire working process, the follower mechanism 5 responds to the rotation of the cable roller 3 in real time, and realizes the synchronous movement of the support frame 2 through precise mechanical transmission; the cable guide 6 ensures the stability of the cable traction path; the speed regulating box 7 dynamically adjusts the moving speed according to the cable status. The three work together to effectively protect the safety of the cable and improve construction efficiency. At the same time, the setting of the waist-shaped groove 510 in the mobile guide unit 51 enables the semicircular contour of the waist-shaped groove 510 to be used for reversing during the reciprocating movement of the mobile base 50, which can further avoid the impact caused by inertia during direct reversing in the linear reciprocating movement of the transmission, and further improves the traction stability.

[0034] The embodiments of the present application are described above in conjunction with the accompanying drawings. Unless there is a conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.

When the angle is too large, the speed regulating wheel (75) is controlled to move and squeeze the transmission steel belt (73), thereby changing the transmission ratio of the speed regulating box (7), and finally completing the moving speed adjustment of the mobile base (50).
