Abstract
The invention discloses a hydraulic bracket belonging to the field of coal-mining machinery. The hydraulic bracket comprises a base, a top beam and a shield beam, wherein an upright is hinged between the base and the top beam, a front connecting rod and a rear connecting rod are hinged between the shield beam and the base, a tail beam is hinged on the tail end of the top beam, a tail beam jack is hinged between the shield beam and the tail beam, and a waste filling device is arranged on the lower part of the tail beam. The hydraulic bracket can realize the simultaneous operation of underground coal mining and waste filling. The tail jack between the top beam and the tail beam plays a role in supporting the tail beam, and thus the stability of the tail beam is ensured. In addition, the tail beam swings through the movement of the tail beam jack, and the state of the tail beam is regulated, so that waste filling adapts to different coal mining environments and especially meets the requirement on layer mining of coal beds with dirt band layers, the range of the waste filling is enlarged, and the filling operation is more flexible.
Description
Technical field
The present invention relates to fully-mechanized coalface support apparatus under the coal mine, particularly relate to a kind of hydraulic support that is applicable to the coal seam separate zone production of dirt band layer.
Background technology
Rich coal resources in China, the civilian and industrial energy is high to the dependency degree of coal.Be accompanied by the high development of China's economy, and the demand brought of other energy deficiencies, the exploitation quantity of coal also will further improve.But thing followed problem is day by day serious owing to dealing with the coal mining environmental disruption problem that causes improperly.
As everyone knows, in the recovery process of coal, can produce a large amount of gangues.Gangue is the solid waste that discharges in coal mining process and the coal washing process, be a kind of lower with a kind of phosphorus content of coal seam association in coalification course, than the hard black gray expandable rock of coal, comprise the spoil of washing of choosing the spoil of extraction in top board, base plate and interlayer in digging gangue in the tunnelling process, the mining process and the coal washing process.Although gangue has certain value, in view of utilizing the higher problem of cost, only have few part to be utilized in the gangue.A large amount of undressed gangues can only be deposited in ground behind the coal mining, the ground hillock of formation.This not only can affect the atmosphere pollution that utilizes of Land resources, because gangue air storage meeting produces a large amount of airborne dusts, will worsen the quality of mining area atmosphere simultaneously, also can endanger water and soil.
For solving " hillock " problem, China progressively adopts in technology such as filling minings, gangue is fills up to the goaf solves the gangue treatment problem.It is exactly to utilize digging space (tunnel, goaf) that mining forms as the place that stores refuse that gangue is filled the goaf, and the final disposal that gangue is carried out.
But thing followed problem is that waste filling will certainly increase the coal work amount and improve mining costs.Carry out in addition waste filling after the coal mining and greatly reduce coal mining speed and efficient.
Summary of the invention
In order to improve coal mining efficient, be implemented in the synchronous operation of mining under the different subsurface environments with waste filling, the invention provides a kind of coal mining support, the integrated hydraulic support of filling.
A kind of hydraulic support of the present invention, comprise base, back timber, caving shield, described back timber and described caving shield are hinged, between described base and described back timber, be hinged with column, be hinged with front rod and back link between described caving shield and the described back timber, the tail end of described caving shield is hinged with tail boom, also is hinged with the tail boom jack between described caving shield and the described tail boom.
A kind of hydraulic support of the present invention, the bottom of described tail boom is provided with the waste filling device.
A kind of hydraulic support of the present invention, described waste filling device comprises the chute that is arranged at the tail boom lower end, the scratch board conveyor that can move in chute.
A kind of hydraulic support of the present invention, the front end of described base is provided with advancing jack.
The beneficial effect of technical scheme provided by the invention is: top beam rear end of the present invention is hinged tail boom, be provided with the waste filling device in the bottom of tail boom, and can realize underground coal exploitation and simultaneously operation of waste filling.
Simultaneously, between back timber and tail boom, also be hinged with the tail boom jack, played the supporting role to tail boom, guaranteed the stability of tail boom.Can realize the oscillating motion of tail boom by the motion of tail boom jack, regulate the state of tail boom, and then make waste filling adapt to different coal mining environment, particularly satisfy the coal seam separate zone production of band dirt band layer, increased the scope that spoil is filled, made packing job more flexible.
Description of drawings
Fig. 1 is the structural representation of a kind of hydraulic support of providing of the embodiment of the invention.
The specific embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
As shown in Figure 1, hydraulic support of the present invention mainly is comprised of base 8, back timber 1, caving shield 3, tail boom 6, column 2 and connecting rod more than 7 parts.
This hydraulic support be base 8 bottom, be hinged with at least one group of column 2 on the base, the upper end of column 2 and back timber 1 are hinged.The rear end of back timber 1 is provided with caving shield 3.Caving shield 3 lower hinge have connecting rod 7, and the bottom of connecting rod 7 and base 8 are hinged.Usually, connecting rod is set to two groups, is respectively front rod and back link.The constitutionally stable four-bar linkage structure of the common formation of front rod, back link, back timber and base.
Be hinged with tail boom 6 in the rear end of caving shield 3.Also be connected with tail boom jack 5 between tail boom 6 and the caving shield 3.One end of tail boom jack 5 is articulated in caving shield 3, and the other end is articulated in tail boom 6.Tail boom jack 5 has been realized supporting role to tail boom 6 on the one hand, has guaranteed the stability of tail boom; On the other hand, the motion by tail boom jack 5 can drive tail boom 6 with respect to the motion of caving shield 3.
Be provided with waste filling device 10 in the bottom of tail boom 6.For the ease of settling waste filling device 10, tail boom 6 adopts body structures, is provided with abreast chute at bottom and the tail boom 6 of tail boom 6.In addition waste filling device 10 also comprise can be in chute along the scratch board conveyor of runner movement.Scratch board conveyor can along runner movement, be transported to spoil in the goaf of hydraulic support rear end by the effect of jack.
In addition, for the facility of hydraulic moving stand, also be provided with advancing jack 9 at the front end of hydraulic support foundation 8.
The back timber rear portion of hydraulic support of the present invention is provided with tail boom, can realize underground coal exploitation and simultaneously operation of waste filling, has improved waste filling efficient.Being arranged at tail boom jack between hydraulic support shield beam and the tail boom has increased the stability of tail boom, can adjust according to the needs of subsurface environment simultaneously the state of tail boom, has improved the flexibility of waste filling.
