Description
Technical field
The utility model relates to a kind of anchor pole, in particular to a kind of extensible formula protecting against shock anchor pole.
Background technique
Currently, deep roadway with large deformation surrounding rock supporting mainly uses the structure of anchor pole, anchor cable and the combination of anchor net.This supporting
Form is comparatively laborious, and the effect of supporting is not significantly improved, and especially constantly increases in mining depth, and geological conditions is got over
Come more complicated, roadway surrounding rock destroys under serious environment, and the requirement for anchor pole will be more special.
Summary of the invention
In order to solve the above-mentioned technical problem, the utility model provides the extensible formula that a kind of structure is simple, applied widely
Protecting against shock anchor pole.
The technical solution that the utility model solves the above problems is: a kind of extensible formula protecting against shock anchor pole, including rod end connect
Head, the body of rod, resilient sleeper-bearing, nut, the body of rod both ends be equipped with external screw thread, the both ends of the rod ends be all provided with it is fluted, it is recessed
The cell wall of slot is equipped with the internal screw thread to match with the external screw thread, and being in turn connected to form several bodies of rod by rod ends can
Extension type anchor structure, extensible formula anchor structure one end body of rod on the outermost side are equipped with protecting against shock mechanism.
Above-mentioned extensible formula protecting against shock anchor pole, the protecting against shock mechanism include nut and resilient sleeper-bearing, the resilient sleeper-bearing
It is socketed on the body of rod on the outermost side of extensible formula anchor structure one end, the nut is located on the outside of resilient sleeper-bearing and screw thread is pacified
On the body of rod on the outermost side of extensible formula anchor structure one end.
Above-mentioned extensible formula protecting against shock anchor pole, the resilient sleeper-bearing include two blocks of I-steel and a spring, two pieces of I-shapeds
Steel is arranged in parallel, and spring is located between two blocks of I-steel and both ends are respectively and fixedly installed on two blocks of I-steel, the extensible
Formula anchor structure one end body of rod on the outermost side passes through two blocks of I-steel, when by shock loading, spring contraction deformation, and storage
Deposit deformation energy.
Above-mentioned extensible formula protecting against shock anchor pole, the groove at the rod ends both ends is interior to be equipped with Anchor Agent.
Above-mentioned extensible formula protecting against shock anchor pole, the groove at the rod ends both ends are not connected to mutually.
The utility model has the beneficial effects that:
1, several bodies of rod are in turn connected to form extensible formula anchor structure by rod ends by the utility model, and are adopted
Dual fixation is carried out to the body of rod with Anchor Agent and screw thread, the inadequate problem of rock-bolt length can be quickly solveed, simplify construction.
2, the utility model is equipped with protecting against shock mechanism on the body of rod on the outermost side of extensible formula anchor structure one end, prevents
Beater mechanism includes nut and resilient sleeper-bearing, and resilient sleeper-bearing includes two blocks of I-steel and a spring, and two blocks of I-steel are set in parallel
It sets, spring is located between two blocks of I-steel and both ends are respectively and fixedly installed on two blocks of I-steel, and the body of rod passes through two blocks of I-steel,
Spring contraction deforms when by shock loading, and storage deformation energy can increase the intensity and non-deformability of suspension roof support.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Fig. 2 is the structural schematic diagram of the utility model rod ends.
Fig. 3 is the structural schematic diagram of the utility model resilient sleeper-bearing.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and examples.
As shown in Figure 1, a kind of extensible formula protecting against shock anchor pole, including rod ends 1, the body of rod 2, resilient sleeper-bearing 4, nut 3,
2 both ends of the body of rod are equipped with external screw thread 7, as shown in Fig. 2, the both ends of the rod ends 1 are all provided with fluted 8, in the groove 8
Equipped with Anchor Agent, the groove 8 at 1 both ends of rod ends is not connected to mutually.The cell wall of groove 8 is equipped with to match with the external screw thread 7
Internal screw thread, several bodies of rod 2 are in turn connected to form extensible formula anchor structure, extensible formula anchor pole knot by rod ends 1
Structure one end body of rod on the outermost side is equipped with protecting against shock mechanism.
The protecting against shock mechanism includes nut 3 and resilient sleeper-bearing 4, and the resilient sleeper-bearing 4 is socketed in extensible formula anchor pole knot
On the body of rod on the outermost side of structure one end, the nut 3 is located at 4 outside of resilient sleeper-bearing and is threadably mounted at extensible formula anchor pole knot
On the body of rod on the outermost side of structure one end.
As shown in figure 3, the resilient sleeper-bearing 4 includes two blocks of I-steel 6 and a spring 5, two blocks of I-steel 6 are set in parallel
It sets, spring 5 is located between two blocks of I-steel 6 and both ends are respectively and fixedly installed on two blocks of I-steel 6, among two blocks of I-steel 6
