Abstract
The utility model relates to an anchor rod capable of being used in dynamic pressure. The anchor rod capable of being used under the dynamic pressure is provided with an interior pressure yielding section and an exterior pressure yielding system of a rock stratum. Anchoring agents are arranged on the exterior of a rod body stretching into the rock stratum in an enclosing mode. The front end of the rod body is the pressure yielding section. A convex supporting plate, a spherical supporting plate, an elastomer, a baffle and a nut are sequentially mounted on a part, on the exterior of a rock wall, of the rod body in a sleeved mode. The spherical supporting plate and the baffle are fixedly connected together through a draw rod, and a spring sleeve is sleeved on the exterior of the draw rod. The anchor rod capable of being used under the dynamic pressure can increase a pressure yielding journey, is simple in structure and easy to operate, avoids occurrence of production accidents, is safe and reliable, and is of great help for normal operation of production.
Description
Technical field
the utility model relates to a kind of anchor pole, the anchor pole that especially a kind of dynamic pressure is used.
Background technology
anchor pole is the element of contemporary colliery tunnel support, and the country rock in tunnel is strapped in together, makes country rock self supporting self.Now anchor pole is not only for mine, also for engineering, and to side slope, tunnel, dam body carries out active reinforcing.Traditional anchor pole in use, stablize constant by the pressure of suffered rock mass, but when in the situation such as concussion of blasting country rock anchor moves lower time, the anchor pole pressure belongs to dynamic pressure, and traditional anchor pole is difficult to bear, easily the production development accident, the harm safety of workers, affect manufacturing schedule.
The utility model content
in order to overcome the technical deficiency of existing anchor pole, the anchor pole that the utility model provides a kind of dynamic pressure to use, the anchor pole that this dynamic pressure is used can increase allows the pressure stroke, and simple in structure, easy operating, avoid the generation of production accident, safe and reliable, the normal operation of producing is had to great help.
the utility model solves the technical scheme that its technical problem adopts: the anchor pole that this dynamic pressure is used comprises the body of rod, Anchor Agent, the convex supporting plate, pull bar, baffle plate, nut, elastic body, spherical supporting plate, the anchor pole that this dynamic pressure is used is provided with inside allows the outside of pressing section and rock stratum allow two parts of pressing system, body of rod outer peripheral in stretching into rock stratum is arranged with Anchor Agent, the front end of the body of rod is pressed section for allowing, the body of rod sequentially is set with the convex supporting plate in the part of crag outside, spherical supporting plate, elastic body, baffle plate and nut, the tail end of the body of rod is fixed with nut, the pull bar that by outer cover brute spring cover is housed between spherical supporting plate and baffle plate is fixed together, the two ends of pull bar are fixed with nut.During use, first allow inside allow to press section be allowed pressures, press stroke to reach to prescribe a time limit when inside allows, start outside and allow pressing system, increase allow the pressure stroke, make the safety and reliability of constructing.
the beneficial effects of the utility model are, the anchor pole that this dynamic pressure is used can increase allows the pressure stroke, and simple in structure, and easy operating, avoid the generation of production accident, safe and reliable, and the normal operation of producing is had to great help.
The accompanying drawing explanation
below in conjunction with drawings and Examples, the utility model is described in further detail.
fig. 1 is structural principle schematic diagram of the present utility model.
in Fig. 1, the 1. body of rod, 2. Anchor Agent, 3. convex supporting plate, 4. pull bar, 5. baffle plate, 6. nut, 7. elastic body, 8. spherical supporting plate, 9. rock stratum, I. allows and presses section.
The specific embodiment
in Fig. 1, the anchor pole that this dynamic pressure is used comprises the body of rod 1, Anchor Agent 2, convex supporting plate 3, pull bar 4, baffle plate 5, nut 6, elastic body 7, spherical supporting plate 8, the anchor pole that this dynamic pressure is used be provided with inside allow press section I and 9 outsides, rock stratum allow two parts of pressing system, the body of rod 1 outer peripheral in stretching into rock stratum 9 is arranged with Anchor Agent 2, the front end of the body of rod 1 is pressed section I for allowing, the body of rod 1 sequentially is set with convex supporting plate 3 in the part of crag outside, spherical supporting plate 8, elastic body 7, baffle plate 5 and nut 6, the tail end of the body of rod 1 is fixing with nut 6, the pull bar 4 that by outer cover brute spring cover is housed between spherical supporting plate 8 and baffle plate 5 is fixed together, the two ends of pull bar 4 are fixed with nut.During use, first allow inside allow to press a section I be allowed pressures, press stroke to reach to prescribe a time limit when inside allows, start outside and allow pressing system, increase allow the pressure stroke, make the safety and reliability of constructing.
