Abstract
The invention discloses a hydraulic support used for supporting and protecting a non-conventional type roadway, which comprises a base, a hydraulic extension upright post arranged on the base, a top beam arranged on the top of the hydraulic extension upright post and a shield beam connected with the back of the top beam; the lower part of the shield beam is hinged with the base via a connecting rod; the top of the hydraulic extension upright post is hinged with the top beam axle hole via a cross axle cap; the back of the top beam is hinged with the top of the shield beam via a cross hinge axle bed. The hydraulic support has the advantage of hinging the back of the top beam and the top of the shield beam via the cross articulated axle bed and the articulated axle and hinging the top of the hydraulic extension upright post and the top axle hole via the cross jack post cap. Therefore, the top beam can rotate along both the horizontal axle and the vertical axle of the cross articulated axle; at the same time, the between part of the hydraulic extension upright post and the top beam can swing in any direction and bear load to support the top beam. In this way, the top beam of the hydraulic support can adjust and support the top plate along the changes of the vertical and the horizontal inclinations of the top plate.
Description
Technical field
The present invention relates to mine and adopt support apparatus, especially relate to the hydraulic support that is used for special-shaped laneway support with combining.
Background technology
The support apparatus that use existing termination, tunnel is as two one group of formula hydraulic supports, standing shield hydraulic support, hydraulic shield support etc., and its back timber can only be done lateral rotation, therefore can only carry out the adjustment at the back timber elevation angle or the angle of depression.If when being used for the special-shaped tunnel of oblique top,, make the generation that badly and easily causes the accident of back timber stress because back timber can not vertically rotate and adjust the vertical angle of back timber.Take the way of unsettled place's filling auxiliary material between set cap and top board to solve the problems referred to above, then need great amount of manpower and material, and operating process is also dangerous.Therefore take roadway opening in the coal seam more in the mining area of many inclined seams, or carry out the tunnel with the monomer pillar that falls behind and support, and not only causes the waste of resource and manpower and materials, and restricted comprehensive raising of adopting efficient.
Summary of the invention
The object of the invention is to provide a kind of back timber to tilt and the hydraulic support that is used for special-shaped laneway support that can carry out the vertical, horizontal adjustment voluntarily according to the back different directions.
For achieving the above object, the present invention can take following technical proposals:
The hydraulic support that is used for special-shaped laneway support of the present invention comprises base, be arranged on the hydraulically extensible column on the described base and be arranged on the back timber on described hydraulically extensible column top, and with the back-connected caving shield of described back timber; Described caving shield bottom is hinged by connecting rod and base; Hydraulically extensible column top is hinged by cross axle cap and back timber needling; The back timber rear portion is hinged by hinged axle bed of cross and caving shield top.
Described cross axle cap for described back timber on the hemispherical shell that adapts of needling radius of curvature, the shell chamber of described hemispherical shell and hydraulically extensible column end shape adapt; Uniform two pairs of hinge holes and the jointed shaft that is arranged in every pair of hinge hole of offering on the close side face of faucal of hemispherical shell.
The jointed shaft of the hinged axle bed of described cross for being opened in two hinge holes on the connector up and down and setting within it, the axis of described two hinge holes is vertical mutually.
Advantage of the present invention just is to take described back timber rear portion is hinged by the hinged axle bed of cross and jointed shaft and caving shield top, and hydraulically extensible column top is hinged by cross axle cap and back timber needling.Therefore, back timber not only can rotate along the transverse axis of described cross jointed shaft but also can rotate along its longitudinal axis; But the swing that can do simultaneously any direction between hydraulically extensible column and the back timber is bearing load power supporting top beam again.Thereby realization hydraulic support back timber can be adjusted and roof supporting voluntarily along the variation at top board vertical, horizontal inclination angle.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the front view of cross axle cap of the present invention.
Fig. 3 is that the A-A of Fig. 2 is to sectional view.
The specific embodiment
As shown in the figure, the hydraulic support that is used for special-shaped laneway support of the present invention comprises base 1, is arranged on the hydraulically extensible column 2 on the described base 1, with the back timber 3 that is arranged on described hydraulically extensible column 2 tops, and with described back timber 3 back-connected caving shields 4; Described caving shield 4 bottoms are hinged by connecting rod 5 and base 1.Hydraulically extensible column 2 tops are hinged by cross axle cap and back timber 3 needlings, like this, but the swing that can do any direction along axis between hydraulically extensible column 2 and the back timber 3 bearing load power supporting top beam 3 again; Back timber 3 rear portions are hinged by the hinged axle bed of cross and jointed shaft and caving shield 4 tops, therefore, back timber 3 not only can rotate along the transverse axis of the hinged axle bed of described cross but also can rotate along its longitudinal axis, to realize back timber 3 being carried out the adaptivity adjustment at vertical, horizontal inclination angle according to the top board actual needs.
Described cross axle cap for described back timber 3 on the hemispherical shell 5 that adapts of needling radius of curvature, the shell chamber of described hemispherical shell 5 and hydraulically extensible column 2 end shapes adapt; Uniform two pairs of hinge holes and the jointed shaft 6,7 that is arranged in every pair of hinge hole of offering on the hemispherical shell 5 close side faces of faucal.Jointed shaft 6 is hinged with hydraulically extensible column 2 tops, and jointed shaft 7 is hinged with back timber 3.
The hinged axle bed of described cross is vertical mutually with the axis of jointed shaft 9,10, two hinge holes that set within it for two hinge holes that are opened in up and down on the connector 8; Back timber 3 is hinged by jointed shaft 9 and connector 8, and connector 8 is hinged by jointed shaft 10 with caving shield 4.
