Abstract
The utility model relates to a colliery is hydraulic support accessory field in the pit, specifically is a prevent empting end between hydraulic support frame and transfer device, include that it transfers the seat at the end on next hydraulic support base to move towards vertical welding along the coal seam slope, the end transfers the seat upward to open along coal seam slope trend has the storage tank that is used for placing end accent jack, and this end transfers the piston end of jack and a last hydraulic support base to support the tight fit, and the welding has the stopper that stretches out the storage tank on the end accent jack cylinder body, and the end is transferred the seat to go up and is installed the apron through the bolt, and this apron is upward opened to have and is used for with the spacing hole of the spacing complex of stopper and is used for wearing to put the through -hole of transferring jack hydraulic pressure pipe in the end. The utility model discloses simple and the convenient operation of assembly when realizing preventing toppling over the effect, can play the effect of displacement fine setting about the base, and is reliable and stable in addition, easy maintenance in the pit, and the specially adapted geographical conditions are complicated, the working face slope is big and the inclination is greater than 20 degrees hydraulic support and uses.
Description
Technical field
The utility model relates to coal mine underground hydraulic support frame accessory field, specifically adjusts device at the bottom of overturning-preventing between a kind of hydraulic support frames, is specially adapted to the hydraulic support that the large and inclination angle of geographical conditions complexity, the work plane gradient is greater than 20 degree and uses.
Background technology
In coal seam, need to use hydraulic support to support tunnel, to avoid having an accident.Complicated and the great work plane of the gradient for geographical conditions, if do not take necessary measure, normal hydraulic support to use under this ambient conditions and to work.Therefore a kind of device that can realize hydraulic support overturning-preventing is needed badly.
Summary of the invention
The utility model needs the problem of anti-tipping apparatus in order to the hydraulic support solved in current inclined seam, provides between a kind of hydraulic support frames and adjusts device at the bottom of overturning-preventing.
The utility model is achieved through the following technical solutions: adjust device at the bottom of overturning-preventing between hydraulic support frames, comprises and move towards the end tune seat of vertical welding on next hydraulic support foundation along seam inclination,
The described end, adjusts on seat and has along seam inclination trend the storage tank adjusting jack for placing the end, the piston end of this end tune jack pushes against with a upper hydraulic support foundation and coordinates, the end, adjusts on jack cylinder body and is welded with the limited block stretching out storage tank, the end, adjusts on seat and is provided with cover plate by bolt, this cover plate has for the spacing spacing hole coordinated of limited block and the through hole adjusting jack hydraulic pipe for placing the end.
Be provided with between next hydraulic support and a upper hydraulic support at the bottom of two overturning-preventings described in the utility model and adjust device, the welding and assembling height of this device can be adjusted according to the model of concrete hydraulic support and work plane.During concrete use, adopt electric hydraulic controlled operation to control the flexible of end tune jack piston end to make to push against between next hydraulic support with a upper hydraulic support frames to coordinate, due to mutually effect can be pushed against between each hydraulic support and adjacent hydraulic support, achieve overturning-preventing effect.In addition, the fine setting moving left and right distance of hydraulic support foundation can also be realized by adjusting at the bottom of overturning-preventing described in the utility model device.
Device is adjusted at the bottom of overturning-preventing between hydraulic support frames described in the utility model, assemble simple and easy to operate, while realizing overturning-preventing effect, the effect that base moves left and right distance fine regulation can be played, and it is reliable and stable, maintenance of underground is convenient, is specially adapted to the hydraulic support that the large and inclination angle of geographical conditions complexity, the work plane gradient is greater than 20 degree and uses.

Fig. 1 is the front view adjusting device between hydraulic support frames described in the utility model at the bottom of overturning-preventing.
Fig. 2 is the lateral view of Fig. 1.
Fig. 3 adjusts the application schematic diagram of device in inclined seam at the bottom of this overturning-preventing.
In figure: adjust seat at the bottom of 1-, adjust jack at the bottom of 2-, 3-limited block, 4-cover plate, 5-ear seat.
Detailed description of the invention
Adjust device at the bottom of overturning-preventing between hydraulic support frames, comprise and move towards the end tune seat 1 of vertical welding on next hydraulic support foundation along seam inclination,
The described end, adjusts on seat 1 and has along seam inclination trend the storage tank adjusting jack 2 for placing the end, the piston end of this end tune jack 2 pushes against with a upper hydraulic support foundation and coordinates, the end, adjusts on jack 2 cylinder body and is welded with the limited block 3 stretching out storage tank, the end, adjusts on seat 1 and is provided with cover plate 4 by bolt, this cover plate 4 has for the spacing spacing hole coordinated of limited block 3 and the through hole adjusting jack 2 hydraulic tube for placing the end.
During concrete enforcement, the described end, adjusts on seat 1 and stretches out the ear seat 5 with next hydraulic support foundation vertical welding.The setting of this ear seat 5 can increase and next hydraulic support foundation contact surface, increases stability, prevents from damaging.
