This kind of passive cable-laying device for the main cable strands of the suspension bridge construction overcomes to a certain extent the "hula hoop" in the process of erecting the cable strands in the construction of the traditional suspension bridge, which causes friction and extrusion between the strands and causes broken belts and loose wires. However, if the total weight of a cable reel reaches 40t~70t, it is required to stop midway, adjust the cable, or stop in an emergency during the cable laying process. Because the weight of a cable reel is relatively large, the moment of inertia is large, and Large, damping mechanism and torque motor are not enough to brake the cable drum

Embodiment Construction
[0016] Below in conjunction with accompanying drawing for further explanation:
[0017] figure 1 Middle 1 torque motor is used as the driving force and braking power of the rope pay-off machine; 2 is the hydraulic push rod brake used for stop braking; 3 is the reduction gear to increase the transmission torque; 4 is the driving shaft, used as the cable reel and belt system The support of the moving disc; 5 is the torque pin, which acts as the rotation of the cable disc; 6 is the belt brake disc, and the friction force of the friction belt generates the braking torque through the brake disc; 7 is the cable disc; 8 is the rack as the rope release The supporting frame of each mechanism of the machine; 9 is the passive end shaft extension of telescopic adjustment, which is used as the support and loading and unloading adjustment of the cable reel; 10 is the groove of the band brake disc.
[0018] figure 2 Among them, 11 is the brake belt, which produces frictional pressure on t...

A suspension bridge main steel wire rope casting machine comprises a torque motor 1, a hydraulic push-rod brake 2, a reduction gear 3, a driving shaft 4, a bearing frame for every mechanism of the rope casting machine, a driven end shaft extension 9, wherein a rope disc 7 is arranged on the driving shaft 4 and the driven end shaft extension 9. The suspension bridge main steel wire rope casting machine is characterized in that the driving shaft 4 further comprises a brake device for stopping the rotation of the rope disk 7. By means of the suspension bridge main steel wire rope casting machine, the rope disc can be braked steadily, damage to the reduction gear and the motor due to an emergency shutdown can be reduced, and the mechanical life is greatly prolonged. The suspension bridge main steel wire rope casting machine can brake steadily and meanwhile shorten the time for placing and replacing the rope disc.
Description
technical field [0001] The invention relates to a construction equipment for laying out the main steel cable of a suspension bridge for a large bridge, in particular to a rope-laying machine for the main steel cable of a suspension bridge. Background technique [0002] Suspension bridge, also known as suspension bridge, refers to a bridge whose main load-bearing member of the superstructure is the cable suspended by the tower and anchored on both banks (or at both ends of the bridge). The main load-bearing component of the suspension bridge is the suspension cable. The suspension cable is composed of many cable strands. Each strand is produced by the production factory and wound on the cable tray, and then transported to the construction site to be released and erected. It is suspended and anchored by the cable tower. On both sides of the strait, the cable erection process is also called rope laying. The erection of the cable strands of the suspension bridge is an important ...
