Description
Technical field
The utility model relates to a kind of mechanism, particularly a kind of bottom raising mechanism.
Background technology
In prior art, as patent ZL201110069451.7 discloses a kind of bottom lifting device of hydraulic support, comprise and lift end jack, also comprise sledge plate, outer end and the described base of described sledge plate are articulated with axis of rotation, its inner end is unsettled, described two ends of lifting end jack are hinged with the middle part of described base and described sledge plate respectively, described sledge plate comprises horizontal part that can be parallel with the base lower plane of described hydraulic support, and described in the angular range of lifting between the axis of end jack and the described horizontal part being parallel to described base lower plane be 0 degree to 45 degree.Thick or hydraulic support for low coal seam during the bottom lifting device of this hydraulic support is not suitable for.
Utility model content
The technical problems to be solved in the utility model is to provide one and goes for medium-thickness seam hydraulic support, is more suitable for hydraulic support for low coal seam; Swing arm can control swinging block and realize swinging, and slideway can also install slide block, facilitates the bottom raising mechanism of slide block movement.
For solving the problems of the technologies described above, the technical solution of the utility model is as follows:
A kind of bottom raising mechanism, comprise gripper shoe, gripper shoe is provided with support otic placode, and gripper shoe is provided with support column, and support column is connected with swing arm, and swing arm is connected with swinging block, and gripper shoe is provided with slide rail, and slide rail is provided with slideway.
Further, described support otic placode is arranged on the front portion of gripper shoe.
Further, described slideway is arranged in the centre position of slide rail.
Further, described swing arm is connected by steady pin with support column.
Further, the top of described gripper shoe is provided with groove.
Further, described gripper shoe is provided with fixing hole.
The beneficial effect of technique scheme of the present utility model is as follows: because gripper shoe is provided with support column, support column is connected with swing arm, swing arm is connected with swinging block, gripper shoe is provided with slide rail, slide rail is provided with slideway, so go for medium-thickness seam hydraulic support, be more suitable for hydraulic support for low coal seam; Swing arm can control swinging block and realize swinging, and slideway can also install slide block, facilitates slide block to move.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model bottom raising mechanism.
Detailed description of the invention
