Abstract
The utility model discloses a cable clamp plate chain, which includes a chain plate, a bushing, an shaft pin, a bolt, a cable tray and a water pipe pressing plate. The cable clamp plate chain cavity is especially provided with a cable and a annular water pipe; the water pipe is arranged inside of the water pipe groove of the tray; the chain plates are connected by the shaft bushing and the shaft pin together in between; the cable clamp plate has function of freely telescoping, which controls radius of gyration of the cable through limiting surface of the chain plate to ensure the cable to remain with a normal radius for a long-term work. Since the rigidity structure of a strip cable clamp plate is strengthened, the strip cable will not be deformed under bending condition in order to improve effect of extending the working life of tables.
Description
One, technical field
A kind of cable clamp chain of the utility model relates to the protective device of silo shearer service cable, discloses a kind of silo shearer power consumption cable clip plate chain especially.
Two, background technology
At present at coal industry, particularly in the coal mining activity, the ubiquity cable is low useful life, trace it to its cause be since coal-winning machine in when work, the flexible bending that cable is subjected to long-term frequent extra small radius pulls, thereby the useful life that the torsional deformation that causes cable reduces cable, round cable can only use about two weeks generally speaking, cable copper wire distortion fracture, and cable is scrapped, cause operating cost big, maintenance is frequent.
Three, summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, improves the useful life of cable, designs a kind of cable clamp chain.Its technology is: comprise axle sleeve, pivot pin, bolt, cable tray and water pipe pressing plate are in interior structure, it is characterized in that: be provided with prong in the carrier bar, carrier bar is made up of inner splint and external splint, the prong bottom is provided with clamping plate rotary spacing face and clamping plate plane of rotation, form one group of cable clamp chain with the carrier bar of cable clamp chain opposite side, the other end of one group of cable clamp chain stretches in the prong of one group of adjacent cable clamp chain, be connected by axle sleeve and pivot pin are active between the prong, the lower end is fixed with the cable tray of laying cable between one group of inner splint, the upper end is fixed with the water pipe groove of laying water pipe, rotate rotational angle α between clamping plate plane of rotation and the clamping plate rotary spacing face around the pivot pin center, β respectively is 10-20 °.
The positive effect of realizing above-mentioned technology is, the cable clamp chain has the function of freely stretching, and the radius of gyration of the confined planes control cable clamping plate chain by clamping plate guarantees that the cable long-term work in normal bending radius, improves the useful life of cable.Example, coal-winning machine is in operation process, service cable is pulled length distance in 200 meters scopes by coal-winning machine, what cable pulled power imputes to the cable clamp chain more than 95%, simultaneously there is the cable clamp chain to define the cable minimum bending radius again, experiment showed, that cable useful life is crooked more than 10000 times.
