Abstract
The utility model relates to a hard roof dislocation anti-shearing reinforced anchor rod. The hard roof dislocation anti-shearing reinforced anchor rod comprises an anchor rod body, a conical nut, a high-strength tray and an anti-shearing casing pipe, wherein the front end of the anchor rod body is connected with the high-strength tray and the conical nut in sequence in the installation direction, the rear end of the anchor rod body is fixed with an anchor rod placing hole, the anti-shearing casing pipe corresponding to the position of a dislocation layer of a rock stratum is arranged outside a rod body of the anchor rod body, and the anti-shearing casing pipe is welded to the anchor rod body. The hard roof dislocation anti-shearing reinforced anchor rod improves the anti-shearing ability of the anchor rod (cable) body at the dislocation position of the rock stratum, prolongs the service life of the anchor rod body, improves the safety of borehole operation, and saves materials.
Description
Technical field
The utility model relates to the back suspension device, the anti-shearing reinforcement anchor pole of especially a kind of tight roof changing of the relative positions.
Background technology
Mine laneway is because the effect of crushing, inharmonious sinking and horizontal changing of the relative positions effect often occur between layers, make roof timbering anchor pole or anchor cable in Rock Bed Dislocation position generation shear failure and lost due anchorage effect, top board roof fall or destruction occur, and for this problem good solution are not arranged also.
The utility model content
In order to address the above problem, the utility model proposes the anti-shearing reinforcement anchor pole of a kind of tight roof changing of the relative positions, improved the anti-shear ability of the anchor pole (rope) of Rock Bed Dislocation position, saved material than the whole raising of anchor pole shearing resistance effect.
The technical scheme that its technical problem that solves the utility model adopts is: the anti-shearing reinforcement anchor pole of a kind of tight roof changing of the relative positions, comprise anchor pole, tapered cup nut, high strength pallet, shearing resistance sleeve pipe, described anchor pole is along the front end of installation direction be linked in sequence high strength pallet and tapered cup nut, and its rear end and anchor pole putting hole are fixed; The outside corresponding Rock Bed Dislocation layer of the body of rod of described anchor pole position is provided with the shearing resistance sleeve pipe, described shearing resistance sleeve pipe and anchor pole welding.
The beneficial effects of the utility model are: the anti-shearing reinforcement anchor pole of this tight roof changing of the relative positions, improved the anti-shear ability of the anchor pole (rope) of Rock Bed Dislocation position, and prolonged the application life of anchor pole, improved the safety of underground work, saved material.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Accompanying drawing 1 is the structural representation of the anti-shearing reinforcement anchor pole of this tight roof changing of the relative positions.
Among the figure, 1. anchor pole, 2. tapered cup nut, 3. high strength pallet, 4. the anchor pole putting hole 5. descends changing of the relative positions rock stratum, 6. goes up changing of the relative positions rock stratum, 7. shearing resistance sleeve pipe, 8. back.
The specific embodiment
In the accompanying drawings, the anti-shearing reinforcement anchor pole of this tight roof changing of the relative positions, comprise anchor pole 1, tapered cup nut 2, high strength pallet 3, shearing resistance sleeve pipe 7, described anchor pole 1 is along the front end of installation direction be linked in sequence high strength pallet 3 and tapered cup nut 2, and its rear end and anchor pole putting hole 4 are fixing; The outside corresponding Rock Bed Dislocation layer of the body of rod of described anchor pole 1 position is provided with shearing resistance sleeve pipe 7, described shearing resistance sleeve pipe 7 and anchor pole 1 welding.
Bore anchor pole putting hole 4 at back 8, spy on or the top board displacement meter is determined the changing of the relative positions position (descending as shown in Figure 1 the position of changing of the relative positions rock stratum 5 and upper changing of the relative positions rock stratum 6) of rock stratum by boring, then for anchor pole 1 correspondence position, be welded and fixed reinforcing with diameter greater than anchor pole 1 diameter and less than the high tensile steel tube of anchor pole putting hole 4 diameters, improved the anti-shear ability of the anchor pole 1 of Rock Bed Dislocation position, improved its shearing resistance effect compared with the whole body of rod increase sleeve pipe at anchor pole 1 and saved material.
Claims (1)
1. anti-shearing reinforcement anchor pole of the tight roof changing of the relative positions, comprise anchor pole (1), tapered cup nut (2), high strength pallet (3), shearing resistance sleeve pipe (7), it is characterized in that: described anchor pole (1) is along the front end of installation direction be linked in sequence high strength pallet (3) and tapered cup nut (2), and its rear end and anchor pole putting hole (4) are fixing; The outside corresponding Rock Bed Dislocation layer of the body of rod of described anchor pole (1) position is provided with shearing resistance sleeve pipe (7), described shearing resistance sleeve pipe (7) and anchor pole (1) welding.
