With the development of power grids, the amount of cables used in various distribution networks is continuously increased, cables are used as main carriers for electric energy transmission and are usually wound on cable reels, and the use amount and the laying workload are huge. At present, when a power system lays a cable, two methods are mainly adopted, one method is to use a crane to pay off, the limitation of a construction site must be considered by using the crane to pay off, if the crane cannot go in the field, the paying off work is difficult, and the operation mode not only needs great physical force of constructors, but also is easy to increase the torque of the cable or damage a cable insulating layer. The other method is that the cable is paid off by a cable pay-off rack or a cable pay-off vehicle, when the cable pay-off rack or the cable pay-off vehicle is used, the cable drum is installed on the cable pay-off rack or the cable pay-off vehicle, in the existing application, the cable drum is generally hoisted by hoisting equipment and placed on the cable pay-off rack or the cable pay-off vehicle, two operators are generally required to be matched, one operator operates the hoisting equipment, the other operator installs a rotating shaft of the cable drum on a rotating support frame of the cable pay-off rack or the cable pay-off vehicle, the operation is complex; then draw cable pay off rack or cable drum carriage by draw gear and carry out the unwrapping wire to the target location, and cable pay off rack need place on flat bottom surface at present, otherwise in dragging cable in-process cable pay off rack probably takes place the condition such as roll, and the cable drum carriage that usually uses is too big, and is required highly to the construction site, still must be equipped with hoisting equipment. In addition, the cable pay-off rack or the cable pay-off vehicle is very labor-consuming to transfer to a narrow place due to frequent change of pay-off places, and needs to be pulled back by a traction machine during transfer or collection, so that the cable pay-off rack or the cable pay-off vehicle is greatly limited by the place, and a plurality of construction places do not have the condition of using a large-scale pay-off vehicle.
In practical application, there is a large amount of occasions and only need lay a small amount of cable conductor, perhaps the thinner condition of cable conductor, and the cable spool is lighter this moment, and weight generally does not exceed 500kg, if directly carry out artifical transport this moment, then operating personnel's load is too big, if continue to adopt hoisting equipment, then inefficiency, the operation is inconvenient, and application scope receives hoisting equipment's restriction.
The existing pay-off device is lack of a brake braking device, when a cable is drawn, the cable is coiled more at first, the quality is larger, the friction force of a pay-off reel of the cable during drawing is larger, the speed of drawing the cable is slower, after the cable on the pay-off reel is drawn more and less, the cable is coiled less, the quality is also reduced along with the cable, the friction force is reduced, the drawing speed is increased, and meanwhile, under the action of inertia, the pay-off reel can continue to rotate after the drawing is stopped, so that the cable is thrown out and falls on the ground, in the process of laying the cable in drawing, the surface of the cable is rubbed with the ground to cause the insulating protective layer to be worn and torn roughly, the service life of the cable is shortened, the insulating layer is worn out and the wire core is exposed outside seriously, and larger potential.
In the prior art, the carrying and releasing quality and efficiency of cables cannot be effectively solved, the cable drum needs to be lifted by a crane from a warehouse to a construction site and placed on a transport vehicle, then workers need to fix the cable drum on a carriage, and after the cable drum is transported to a construction site, cables are released by a crane or a releasing auxiliary device, so that the process is complicated, the labor intensity is high, and the construction efficiency is low. In addition, the whole process has a plurality of links, the torque of the cable is easily increased or the insulating layer of the cable is easily damaged, and hidden dangers are brought to the future power supply safety.
Therefore, the problem is solved by the targeted development, and the personal safety and the good property of the power workers are ensured.
