Abstract
The utility model discloses a single prop anti-skid support rod. The technical scheme is that the single prop anti-skid support rod includes a rod body, an adjusting hole, left and right rotating nuts and semi-round head left and right rotating adjusting screws. The single prop anti-skid support rod is characterized in that the round adjusting hole is arranged at the middle part of the rod body, the semi-round head left and right rotating adjusting screws and the left and the right rotating nuts are arranged on the two ends of the rod body, and the rod body rotates in an adjustable way; as in the diagram, the support rod consists of the rod body (1), the adjusting hole (2), the left and the right rotating nuts (3) and the semi-round head left and right rotating adjusting screws (4 and 5); the round adjusting hole (2) is arranged at the middle part of the rod body (1); the semi-round head left and right rotating adjusting screws (4 and 5) and the left and right rotating nuts (3) are arranged at the two ends of the rod body (1); and the rod body (1) rotates in an adjustable way. When the single prop anti-skid support rod is in use, the handle is inserted into the adjusting hole (2) at the middle part of the rod body (1), so as to adjust the rod body (1) to rotate and further enable the semi-round head left and right rotating adjusting screws (4 and 5) at the two ends of the rod body (1) to stretch out and draw back, as a result, the firmness of the bottom parts of the single prop with different intervals is enhanced, and the difficulty that the bottom part skids under the pressure of the top plate is completely overcome.
Description
Technical field
The utility model relates to mining production support apparatus strut, especially relates to the anti-sliding strut of a kind of individual prop, belongs to mining support apparatus technical field.
Background technology
The individual prop base diameter that the Coal Production existing techniques is used is identical with cylinder diameter, and when the base plate inclination angle during big or pucking place roof weighting increasing, or work plane has the gradient, the hard pillar of base plate to skid easily, is prone to cause potential safety hazard.
Summary of the invention
To above-mentioned deficiency; For addressing the above problem, between two pillars, the spiral strut is set; Its technical scheme of taking is: a kind of individual prop is prevented tuning about sliding strut is by the body of rod, adjustment hole, left and right sides spin nut, cup head the joint leading screw and is formed; It is characterized in that: body of rod middle part is provided with round adjustment hole, and body of rod two ends are provided with and tune joint leading screw and left and right sides spin nut about cup head, and the body of rod is the scalable rotation.
The beneficial effect of the utility model is: have the gradient, the hard pillar of base plate to carry out supporting when skidding easily at work plane; Guaranteed the setting load of pillar; Reduce the phenomenon that collapses, the damaged condition of pillar, reduced maintenance and maintenance cost, alleviated working strength of workers; Improve the supporting quality of work plane, guaranteed Safety of Coal Mine Production.
Description of drawings
Accompanying drawing 1 is the utility model structural representation.In the drawings: 1, the body of rod; 2, adjustment hole; 3, left and right spin nut; 4, the left-handed adjusting leading screw of cup head; 5, leading screw is regulated in cup head dextrorotation.
The specific embodiment
Shown in accompanying drawing: a kind of individual prop is prevented tuning about sliding strut is by the body of rod 1, adjustment hole 2, left and right sides spin nut 3, cup head joint leading screw 4,5 and is formed; It is characterized in that: the body of rod 1 middle part is provided with round adjustment hole 2; The body of rod 1 two ends are provided with and tune joint leading screw 4,5 and left and right sides spin nut 3 about cup head, and the body of rod 1 is the scalable rotation.
During use; Can insert the body of rod 1 middle part adjustment hole 2 through handle, regulate the body of rod 1 rotation, make to tune joint leading screw 4,5 about the cup head of two ends and stretch; Realize the fastness of different spacing individual prop bottom, the bottom of causing when thoroughly the solving roof weighting difficult problem of skidding.Basically stop the phenomenon that pillar collapses, guaranteed the supporting intensity and the safety of work plane.
Claims (1)
