The technical field is as follows:

the utility model relates to a coal mine equipment technical field especially relates to a strutting arrangement that is arranged in coal-winning machine to bow to adopt the in-process.

Background art:

in the underground coal mine mining process, during the arrangement of a coal face, the situation of large-angle downward mining of the fully mechanized coal face in the coal mining process is easily caused due to the influence of geological conditions and the large-gradient fluctuation change of an air inlet crossheading and an air return crossheading; in terms of down mining, the coal mining machine is applicable to a coal bed with an inclination angle of +/-8 degrees under the normal use condition, if the inclination angle is-10 to-15 degrees, the coal mining machine inclines towards the coal wall direction in the coal mining process, the gravity center is deviated towards the coal wall direction, the coal cutting falls off in the traveling process easily, the cutting stress direction is not parallel to the traveling stress direction, the cutting stress is weakened, the designed cutting depth is difficult to achieve, the coal mining efficiency is greatly influenced, and the skid shoe is easily damaged to cause the fault of the coal mining machine.

The utility model has the following contents:

an object of the utility model is to provide a strutting arrangement for coal-winning machine is bow to adopt in-process.

The content of the utility model is as follows: a supporting device used in the coal mining machine diving process comprises a horizontally arranged bottom plate, a square barrel is vertically and fixedly installed on the bottom plate, a baffle is horizontally arranged in the square barrel, sliding blocks are horizontally and outwards fixedly installed on the front side and the rear side of the baffle, a sliding through groove matched with the sliding blocks is vertically formed in the outer wall of the square barrel, the sliding blocks are in sliding connection with the sliding through groove, limiting holes are horizontally and inwards formed in the left side and the right side of the baffle, a plurality of threaded through holes matched with the limiting holes are formed in the outer wall of the square barrel in the vertical direction, a limiting bolt penetrates through the threaded through holes and is in threaded connection with the threaded through holes, the tail end of the limiting bolt is inserted into the limiting holes, and an inverted T-shaped sleeve is horizontally and fixedly installed at the top end of the square barrel, telescopic centre bore and slip post sliding connection, the horizontal fixedly connected with spacing dish in bottom of slip post, the top fixed mounting of slip post has curved contact head still the vertical compression spring that installs in the square barrel, compression spring's bottom with baffle fixed connection, compression spring's top with spacing dish contacts, spacing dish is located in the square barrel.

Furthermore, the reinforcing rib is obliquely arranged, the top end of the reinforcing rib is fixedly connected with the outer wall of the sleeve, and the bottom end of the reinforcing rib is fixedly connected with the bottom plate.

The utility model has the advantages that: the utility model discloses simple structure, design dedicated elastic support device and prevent that the coal-winning machine from empting the machine to the coal wall direction, it is unanimous with the cutting stress direction to make coal-winning in-process coal-winning machine walking stress direction, it supports to make the coal-winning machine be formed with power between supporting balancing unit and the coal wall at the in-process of bowing, thereby improve the coal mining tunnelling degree of depth, the contact head that supports flat device and coal wall designs into the arc and has elasticity, can adjust the support distance by oneself under the condition of coal wall unevenness, prevent that the skid shoe from damaging, reduce the equipment maintenance number of times, be worth using widely on a large scale.

Description of the drawings:
