Abstract
The utility model discloses a high-strength deformation-resistant anchor rod angle adjusting pallet, which comprises a convexly spherical pallet body. A hemispherical anchor hole is designed exactly at the top of a sphere; a hemispherical cushion block is arranged in the hemispherical anchor hole; and the middle of the hemispherical cushion block is provided with a through hole adapting to the diameter of an anchor rod. When the high-strength deformation-resistant anchor rod angle adjusting pallet is used, the anchor rod is inserted into the hemispherical cushion block, and the hemispherical cushion block is capable of rotating in the anchor hole within a certain angle. When the direction of a drilled hole (an anchor rod hole) is deviated from a roadway wall, the direction of the anchor rod can be adjusted according to the direction of the drilled hole so that the anchor rod and the pallet are constantly kept in even stress along the positive pressure direction, the shear force of the pallet to the anchor rod is resisted effectively, the pallet and the anchor rod are not damaged, and the support strength of a roadway is ensured.
Description
Technical field
The utility model relates to the pallet of using in the mine bolt supporting.
Background technology
The anchor pole pallet that coal mine roadway bolt support is at present adopted is protruding spherical pallet, and sphere just place, top design has anchor hole.Because in the anchor pole installation process, bore angle is not necessarily up to specification fully, the ball top support force direction generation deflection of the direction of pull of anchor pole and pallet, cause the phenomenon of shearing anchor rod body to take place easily, when pallet hemisphere jut place discontinuity, will weaken the intensity of pallet and stressed uniformity, cause pallet at the bottom of the hole, to destroy and distortion, influence effective control in Anchoring Strength of Rock Bolts and tunnel.
Summary of the invention
The utility model has designed a kind of novel high-strength resistance to deformation anchor pole angle modulation pallet for addressing the above problem.
A kind of high-strength resistance to deformation anchor pole angle modulation pallet, it comprises protruding spherical tray body, sphere just place, top design has anchor hole, it is characterized in that, described anchor hole is the hemispherical anchor hole, hemispherical cushion block of configuration in the hemispherical anchor hole, and the centre of hemispherical cushion block is provided with the through hole adaptive with bolt diameter.
The utility model has the advantages that: during use, anchor pole is inserted in the hemispherical cushion block, the hemispherical cushion block can rotate in certain angle in anchor hole, when hole (bolthole) direction and tunnel wall have deflection, anchor pole can be adjusted direction thereupon, and it is stressed evenly to make itself and pallet remain the normal pressure direction, effectively resists the shearing force of pallet to anchor pole, pallet and anchor pole are not destroyed, guarantee the supporting intensity in tunnel.
Description of drawings
Fig. 1 is the front view of the utility model embodiment.
The protruding spherical tray body of marginal data: 1-; 2-hemispherical anchor hole; 3-hemispherical cushion block; The 4-through hole; The 5-anchor pole.
The specific embodiment
As shown in Figure 1, high-strength resistance to deformation anchor pole angle modulation pallet of the present utility model comprises protruding spherical tray body 1, the sphere of protruding spherical tray body 1 just place, top design has hemispherical anchor hole 2, hemispherical cushion block 3 of configuration in the hemispherical anchor hole 2, the centre of hemispherical cushion block 3 is provided with the through hole 4 adaptive with anchor pole 5 diameters.
