Abstract
Utility model discloses a kind of coal-mine hydraulic support base back link jointed shaft stopping means, comprises hydraulic support foundation, is plugged in two back link jointed shafts between rear portion two main gusset and respective side backplate; Two main gusset medial surfaces are respectively arranged with stopping means: comprise the U-shaped pasting board being fixed on main gusset medial surface, the back link hinge hole be opened on main gusset is positioned at the upper shed of U-shaped pasting board, the plate face of U-shaped pasting board is fixed with guide and limit plate, pass a bridge after being positioned at hydraulic support foundation upper corresponding to upper shed place of U-shaped pasting board, spaced apartly be provided with two jacks and limit bolt, the lower end of limit bolt extends in the upper shed of U-shaped pasting board, and the thickness of limit bolt and width and annular slot adapt; Offer spacer pin axis hole at the top of limit bolt, on passing a bridge after being positioned at the hydraulic support foundation at spacer pin axis hole place, be fixed with connection otic placode.The utility model solves regulating mechanism at the bottom of adjacent hydraulic support and damages the problem of stopping means because of extruding.
Description
Technical field
The utility model relates in large inclination working surface adjusts the hydraulic support of structure the end of with, especially relates to coal-mine hydraulic support base back link jointed shaft stopping means.
Background technology
In the distribution of the numerous coal resources of China, large-inclination-angle coal bed storage capacity accounts for greatly 14.05% of coal gross storage capacity, and its annual production accounts for greatly the 8%-10% of national coal total output.Therefore, mechanical mining is large-inclination-angle coal bed is the technical barrier of coal mining industry always.Due to the particularity of working face of coal seam condition, fully-mechanized mining working surface hydraulic support needs to increase the position regulator end of such as between the anti-skid that adapts and frame and adjusts beam etc.In the actual recovery process of large inclination working surface, due to the existence at base plate inclination angle and the reason of hydraulic support self special construction, can not ensure completely parallel between adjacent hydraulic support foundation, when this is positioned between two framves with regard to the limited block causing hydraulic support foundation back link jointed shaft, move in frame process the extruding scratch and damage inefficacy that are subject to regulating mechanism at the bottom of adjacent frame hydraulic support, and then cause the left and right of back link jointed shaft to collect together out.Because service clearance under mine is little and condition is limited, keep in repair very difficult.
Summary of the invention
The utility model object is to provide a kind of coal-mine hydraulic support base back link jointed shaft stopping means.
For achieving the above object, the utility model adopts following proposal:
Coal-mine hydraulic support base back link jointed shaft stopping means described in the utility model, comprises hydraulic support foundation, is plugged in two back link jointed shafts between described hydraulic support foundation rear portion two main gusset and respective side backplate, described two main gusset medial surfaces are respectively arranged with the identical stopping means of a structure, described stopping means comprises the upper shed U-shaped pasting board being fixed on main gusset medial surface, the back link hinge hole be opened on main gusset is positioned at the upper shed of described upper shed U-shaped pasting board, the plate face of upper shed U-shaped pasting board is fixed with guide and limit plate, pass a bridge after being positioned at hydraulic support foundation and above correspond to upper shed place of upper shed U-shaped pasting board, spaced apartly be provided with two jacks and put limit bolt in the inner, the lower end of described limit bolt extends in the upper shed of upper shed U-shaped pasting board, the thickness of limit bolt and width and the annular slot being opened in back link jointed shaft end adapt, offer spacer pin axis hole at the top of limit bolt, be fixed with connection otic placode on passing a bridge after being positioned at the hydraulic support foundation at described spacer pin axis hole place, collect together out to prevent spacer pin axle.
The utility model advantage is do not have position limiting structure between adjacent hydraulic support, solves the end regulating mechanism moving adjacent hydraulic support in frame process damages stopping means problem because of extruding.Reduce the labour intensity of service worker, enhance productivity.Limit bolt can be installed from base exterior, easy accessibility, has certain interval after being in place with the upper shed bottom of upper shed U-shaped pasting board, can prevent it to drop loss by gravity.Upper shed U-shaped pasting board and guide and limit plate can leave certain gap when fixing, and are conducive to like this getting rid of foreign material float coal.
