The brake disc 16 and the braking device 17 can have two sets or one set, and one set is adopted in the present embodiment. Through this device, the frictional damping during the rotation of the cable reel can be adjusted to prevent the cable reel from being unable to stop due to inertia during an emergency stop and continuing to pay off.

Further, referring to Fig. 4, Fig. 5 and Fig. 8, as a specific embodiment of the cable pay-off vehicle provided by the present invention, the underframe 1 is provided with a buffer device 18 for positioning the position of the cable reel, The buffer device 18 is arranged perpendicular to the axial direction of the rotating shaft of the cable reel. The buffer device 18 includes a positioning rod 1801 for adjusting the positioning position and a buffer 1802 for buffering the cable reel. The axes of the positioning rod 1801 and the buffer 1802 are in the same direction as the cable reel rolls in, and are fixed on the chassis 1 by means of a mounting block. superior. The positioning rod 1801 is preferably a screw, and the position of the positioning rod 1801 can be adjusted so that the stop position of the cable reel is above the safety chuck 5. The buffer 1802 is preferably a hydraulic buffer for absorbing the energy when the cable reel rolls in. To avoid its impact on the pay-off car, when the buffer 1802 is in a free state, the distance between the end of the buffer 1802 and the mounting block is greater than the distance between the end of the positioning rod 1801 and the mounting block. The buffer can absorb the energy of the cable reel when it rolls in, avoiding the impact of the cable reel on the base. liter, save time and improve efficiency.

Further, referring to Fig. 1 and Fig. 2, as a specific embodiment of the cable pay-off vehicle provided by the present invention, the bottom frame 1 is provided with a fixing screw 20 for fixing the cable pay-off vehicle, and is fixed on the bottom frame 1. There is a fixed block 19 for threading engagement with the fixed screw rod 20 , and the fixed screw rod 20 runs through the fixed block 19 . Rotating the fixing screw 20 can make the fixing screw 20 contact with the ground to fix the cable pay-off vehicle.

Further, referring to Fig. 1 and Fig. 2, as a specific embodiment of the cable pay-off vehicle provided by the present invention, the wheels 101 arranged at the bottom of the underframe 1 are preferably universal wheels with brakes, which can realize cable release. The wire car rotates in situ.

Further, as a specific embodiment of the cable pay-off vehicle provided by the present invention, the side of the first support frame 2 away from the second support frame 6, that is, the front end of the cable pay-off vehicle is provided with a traction mechanism, which can be controlled by external equipment. Traction and drive of cable pay-off vehicles.

The above descriptions are only preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the protection of the present invention. within range.
