Abstract
The utility model relates to an anchor rope anti-shock mounting of high stress tunnel group portion belongs to coal mine tunnel and struts technical field. Including cylindrical sleeve, soft medium and thin spring, cylindrical sleeve on be equipped with four rings, cylindrical sleeve's diameter is greater than the diameter of anchor rope, cylindrical sleeve cup joints on the anchor rope, thin spring is connected to the ring, the anchor net is connected to the other end of thin spring, soft medium is filled and is separated with annular gasket between cylindrical sleeve's bottom and anchor rope. The utility model has the advantages that: the device has small volume, simple structure, low cost and convenient installation; the device has two parts of buffering and energy absorbing design, so that kinetic energy during punching can be effectively absorbed at the moment when the anchor cable is broken and punched, and punching force is reduced, so that the broken anchor cable stays in the cylindrical sleeve, and the safety of pedestrians in a roadway is ensured; the device can be recycled and reused, and has good practical value.
Description
Technical Field
The utility model relates to an anchor rope anti-shock mounting of high stress tunnel group portion belongs to coal mine tunnel and struts technical field.
Background
With the further development of coal mines in China to the deep part, the problems of complex geological structures and high stress faced by roadway engineering are more and more prominent. The main body structure of the anchor cable arranged on the side part of the high-stress roadway is a steel strand, the main body structure has poor extensibility and weak impact resistance, and the tail end frequently generates a rushing-out phenomenon after being broken. The invention further discloses a device for preventing the anchor cable on the side part of the high-stress roadway from being broken and then rushing out.
Disclosure of Invention
In order to overcome above-mentioned prior art's weak point, the utility model provides a high stress tunnel group anchor rope anti-shock mounting for after the tunnel is strutted, when big load impact and instantaneous deformation caused the anchor rope to break, can prevent effectively that the anchor rope tail end from rushing out and hindering the people, guarantee tunnel pedestrian's safety.
The utility model discloses a realize through following technical scheme: the utility model provides a high stress tunnel group anchor rope anti-shock mounting which characterized in that: including cylindrical sleeve, soft medium and thin spring, cylindrical sleeve on be equipped with four rings, cylindrical sleeve's diameter is greater than the diameter of anchor rope, cylindrical sleeve cup joints on the anchor rope, thin spring is connected to the ring, the anchor net is connected to the other end of thin spring, soft medium is filled and is separated with annular gasket between cylindrical sleeve's bottom and anchor rope.
The circular rings are arranged on the cylindrical sleeve at intervals of 90 degrees.
The circular ring is welded with the cylindrical sleeve.
The thin spring has good tensile property, two ends of the thin spring are provided with hooks, and the hooks are connected with the circular ring and the anchor net.
The utility model has the advantages that: the device has small volume, simple structure, low cost and convenient installation; the device has two parts of buffering and energy absorbing design, so that kinetic energy during punching can be effectively absorbed at the moment when the anchor cable is broken and punched, and punching force is reduced, so that the broken anchor cable stays in the cylindrical sleeve, and the safety of pedestrians in a roadway is ensured; the device can be recycled and reused, and has good practical value.

Detailed Description
An anchor rope scour protection device for high-stress roadway side part shown in figures 1 to 4 is characterized in that: including cylindrical sleeve 1, soft medium 2 and thin spring 4, cylindrical sleeve 1 on be equipped with four rings 11, cylindrical sleeve 1's diameter is greater than the diameter of anchor rope 6, cylindrical sleeve 1 cup joints on anchor rope 6, thin spring 4 is connected to ring 11, anchor net 5 is connected to the other end of thin spring 4, soft medium 2 fills and separates with annular gasket 3 between cylindrical sleeve 1's bottom and anchor rope 6.
The circular rings 11 are arranged on the cylindrical sleeve 1 at intervals of 90 degrees.
The circular ring 11 is welded with the cylindrical sleeve 1.
The thin spring 3 has good tensile property, hooks are arranged at two ends of the thin spring, and the hooks are connected with the circular ring 11 and the anchor net 5.
The utility model discloses after having installed anchor rope 6 during the use, pack a certain amount of soft medium 2 in cylindrical sleeve 1, put into circular gasket 3. The filled cylindrical sleeve 1 is mounted on the tail end of the anchor cable 6. Four thin springs 4 are used for connecting the cylindrical sleeve 1 and the anchor net 5, and hooks at two ends of each thin spring 4 are hung on the ring 11 of the sleeve and the anchor net 5 respectively, so that the thin springs 4 are in a stretching state, and the installation is completed.
