The elastic pull rods 20 are symmetrically arranged on the upper end surface and the lower end surface of the coal mining machine body 10 close to the two side edges.
The working principle and the beneficial effects of the technical scheme are as follows: in the working process of the coal mining machine, each part of the whole coal mining machine can be subjected to larger impact force and torsional moment. And particularly, the stress at the connection part of the whole framework of the coal mining machine body is more obvious. The long-time operation often causes the direct fracture of the connecting bolts among the left traction box 11, the electric control box 12 and the right traction box 13 on the coal mining machine body 10. Four elastic pull rods 20 are arranged at four corners among the left traction box 11, the electric cabinet 12 and the right traction box 13, and two ends of each elastic pull rod 20 are respectively fixed on the surfaces of the left traction box 11 and the right traction box 13. The elastic pull rod 20 is a pull rod with a certain telescopic capability, so that part of coal mining impact force can be offset for each connecting part when the coal mining machine works, and the original connecting components bear less impact force and torsional moment.
The beneficial effects of the above technical scheme are that: the utility model discloses a coal-winning machine bulk joint intensity and reliability with long pull rod of elasticity all obtain promoting to can avoid taking place the condition that similar coupling bolt is twisted off, reduced the equipment overhaul number of times, reduced the consumption of corresponding accessory, prolonged the life of equipment simultaneously.

a second pressing plate 32 having the same shape and size as the first pressing plate 31, the second pressing plate 32 being disposed opposite to the first pressing plate 31;
the pull rod fixing groove 33 is formed between the first pressing plate 31 and the second pressing plate 32 which are oppositely arranged, the elastic pull rod 20 is arranged in the pull rod fixing groove 30, and the width of an opening above the pull rod fixing groove 33 is smaller than the diameter of the elastic pull rod 20.
In addition, the end surfaces of both sides of the electric cabinet 12 are provided with connecting flanges 14, the connecting flanges 14 are provided with through holes allowing the elastic pull rod 20 to pass through, two ends of the first pressing plate 31 and the second pressing plate 32 are integrally formed with fixing support plates 34, and the fixing support plates 34 are fixedly connected with the coal mining machine body 10.
In addition, the heights of the first pressing plate 31 and the second pressing plate 32 are smaller than the height of the connecting flange 14.
The working principle and the beneficial effects of the technical scheme are as follows: in order to avoid the effect of the elastic pull rod 20 on improving the connection strength due to the fact that the elastic pull rod 20 moves around in the working process of the coal mining machine, the elastic pull rod 20 is easy to scratch a sharp edge part during moving, so that cutting marks are generated on the surface of the elastic pull rod 20, and a pull rod fixing device 30 is arranged on the surface of the coal mining machine body 10 and used for fixing the position of the elastic pull rod 20 relative to the coal mining machine body 10. The elastic pull rod 20 is locked in the pull rod fixing groove 33 through two opposite inverted L-shaped structures, so that the elastic pull rod can only stretch along the length direction of the elastic pull rod and cannot move around.
In an embodiment of the present invention, both ends of the elastic tension rod 20 are connected to the surface of the shearer body 10 through the hinge assembly 40, and the hinge assembly 40 includes:
the male connector 41 is of a square structure, two ends of the male connector are respectively and integrally provided with a metal flexible supporting part 42, the metal flexible supporting part 42 positioned at the bottom is fixedly connected with the end face of the coal mining machine body 10, the metal flexible supporting part 42 positioned above is a free end, and a through hinge hole is formed in the side face of the male connector 41;
female connecting piece 43 is the tripod plate structure, female connecting piece 43's side is provided with round pin axle 44, round pin axle 44 with hinge hole clearance fit.
In addition, a protective outer frame 45 is further arranged on the periphery of the male connector 41, the male connector 41 is contained in the protective outer frame 45, elastic buffer blocks 46 are fixedly arranged on two side faces, opposite to the protective outer frame 45, of the male connector 41, and the elastic buffer blocks 46 are semi-cylindrical.
In addition, the pin shaft 44 is locked on the female connector 43 through a locking block 47, the locking block 47 is attached to the outer end face of the female connector 43, and the locking block 47 is fixedly connected with the female connector 43 through a screw 48.
The working principle and the beneficial effects of the technical scheme are as follows: if the elastic pull rod 20 is fixed through the nut, after the elastic pull rod is used for a period of time, the connection between the nut and the coal mining machine body 10 is loosened, and the technical effect of enhancing the connection strength of the elastic pull rod 20 is greatly influenced. In order to offset the impact force applied to the coal mining machine body 10 during the operation process, the original best state is that when the impact generates a small-distance displacement, the impact force is offset by the compression or extension of the elastic pull rod 20, and if the nut is loosened, the small distance generated by the impact is seriously reduced, so that the elastic pull rod 20 cannot achieve the best offset effect. The elastic tension rod 20 is thus fixed by the hinge assembly 40. When the elastic pull rod 20 is stressed, the metal flexible supporting parts 42 at the two ends of the male connecting piece 41 can play a certain buffering role, and meanwhile, the elastic buffering blocks 46 fixed at the two sides of the male connecting piece 41 and the protective outer frame 45 can also play a further buffering role under the mutual contact action, that is, the impact force generated by the coal mining machine body 10 can be transmitted to the joint between the elastic pull rod 20 and the coal mining machine body 10 through two buffering structures, so that the connection strength between the coal mining machine body 10 and the elastic pull rod 20 is greatly improved.
Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications and variations can be made in the embodiments or in part of the technical features of the embodiments without departing from the spirit of the present invention.
