Description
Technical Field
The invention relates to the technical field of coal industry, in particular to an advanced reinforced support bracket and a method for moving the advanced reinforced support bracket.
Background
In order to prevent deformation, movement and damage of surrounding rock of a roadway caused by superposition of advanced supporting pressure and supporting pressure along an inclined direction of a coal face, and ensure smoothness of upper and lower outlets of the coal face, advanced reinforcement support is needed for two roadways of the coal face. The most striking feature of the advance support is that the advance support equipment needs to be continuously moved forward along with the forward pushing of the coal face. According to the method for carrying the domestic advanced support equipment, the advanced support can be divided into five categories of manual carrying, stepping carrying, crawler self-carrying, carrying and monorail crane lifting.
At present, the manual migration advanced support equipment has the outstanding problems of more people, low efficiency, high migration difficulty, high labor intensity of workers, frequent safety accidents in the migration process, serious influence on the improvement of the coal yield and the like.
The stepping hydraulic support can be divided into an integral type advanced support hydraulic support and a split type advanced support group, and the main problem of the stepping moving mode is that the top plate must be repeatedly supported for the requirement of advanced support movement, so that the top plate is easy to break, and the safety management and maintenance of the top plate are not facilitated. The self-moving mechanism used by the stepping hydraulic support can cause serious damage to the roadway bottom plate;
the crawler belt walking type advanced support is a mode of moving a frame under pressure, sliding friction generated by the frame moving mode can seriously affect the service life of the support, and the defects of large forward resistance, unstable walking and the like can be brought, so that the safety of roadway personnel is easily endangered. Meanwhile, when the bottom plate is soft or upslope, the crawler belt walking hydraulic support is difficult to move.
The advanced support bracket set for carrying the trackless rubber-tyred vehicle has the following problems that when the bottom of a roadway floor is bulging or weak mud, the vehicle is difficult to pass under the condition of no load. And by adopting a diesel engine as power, the gate way tail gas is easy to exceed the standard and alarm. Meanwhile, the automobile transportation system occupies a large space and is relatively poor in safety.
When the single track crane is used for lifting and transporting the advanced support equipment, the single track crane takes an anchor rod (rope) above a roadway as a suspension point, and the single track crane needs to be transported and installed forward repeatedly along with the forward movement of a working face, so that the workload of the advanced support is increased. Moreover, the suspension point of the monorail crane is easily influenced by the installation quality, the monorail crane is not firm enough and easily falls down to cause injury accidents, the monorail crane easily swings freely in the middle of a roadway when the advanced support equipment is moved, and great potential safety hazards exist.
Along with the continuous increase of the pushing speed of the working face and the roadway height, the transportation requirement on the forward support equipment of the forward support is continuously improved, and on the premise of ensuring safety, the advanced support transportation speed of the coal face is improved to meet the mining requirement of the working face, and meanwhile, the advanced support equipment can conform to the current age subject of mechanized man-reduction of the coal mine and becomes the technical problem of the current urgent need of the advanced support complete technical equipment.
