At present, a towing device is widely adopted for protecting and towing a power supply cable and an external high-pressure water pipe on a working face. However, the current use condition shows that the problems of protection failure, cable clamp plate deviation, incapability of switching different types of cable clamp plates and the like still exist in the cable towing device, and the requirements on coal mine safety and high-efficiency production are influenced. Therefore, in order to meet the requirements of mechanized, automatic, efficient and rapid mining of coal mine production, research and improvement on the existing towing device are significant.
In the production process of coal mine enterprises, the fully-mechanized excavation becomes a main production process of roadway excavation, a heading machine is an indispensable special device of the fully-mechanized excavation process, and a heading machine following machine cable and a wind-water pipeline move back and forth along with the heading machine and move along with the heading machine. The tunnel bottom plate is repeatedly rolled by the heading machine due to the influences of water spraying in the working face, water flushing in local sections, cutting dust fall, spraying dust fall at drop points and the like in the construction process, so that the sludge in the tunnel is much, and the comprehensive image is extremely poor. The heading machine and the motor cable directly move back and forth in a dragging mode, so that the cable is poor in sanitation, and phenomena such as cable abrasion and extrusion are easily caused in the heading process, so that short circuit or local electric leakage is caused, and a malignant accident is caused. Meanwhile, people must frequently observe the cable on site to prevent scraping, so that personnel waste is caused.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a tunneller reprints tow-cable device for coal mine to solve the problem that proposes among the above-mentioned background art.
In order to achieve the above object, the utility model provides a following technical scheme: a transshipment towing device of a tunneling machine for a coal mine comprises a universal joint, a towing sleeve, an end cover and a plurality of adjusting sleeves, wherein one end of the universal joint is connected with a connecting rod through a bolt, and one end, far away from the universal joint, of the connecting rod is connected with a coal mining machine body through an inner hexagon bolt; one end of the universal joint, which is far away from the connecting rod, is connected with a towing shaft through a bolt, the towing sleeve and a plurality of adjusting sleeves are sleeved on the towing shaft, and the end cover is fixed on the end surface of one end of the towing shaft, which is far away from the universal joint; towing block is arranged at one end of the towing sleeve, and a cable clamp plate is connected to the other end of the towing block through bolts and nuts.
Preferably, the towing sleeve and the towing cable block are of an integral structure.
Preferably, the nut is provided with a pin in a penetrating way, and the pin can prevent the nut from loosening in the using process and ensure that the cable block is stably arranged on the cable clamping plate; the other end of the cable clamp plate is also provided with a bolt for fastening a cable arranged in the cable clamp plate; the coal mining machine is connected with the cable clamping plate, so that the cable has a certain degree of freedom and can move in any direction, and the cable is protected to a certain extent.
Preferably, the number of the hexagon socket head cap bolts fixedly connecting the coal mining machine body and the connecting rod is 2.
Has the advantages that: compared with the prior art, the beneficial effects of the utility model are that:
(1) manual dragging of the cable is not used, so that the manpower resource is saved, and the labor intensity of workers is reduced;
(2) the cable keeps a certain height from the ground, so that the cable is protected, and the cable is prevented from being damaged by dragging the ground;
(3) the failure rate caused by equipment damage is reduced, and the tunneling efficiency is improved.
