Abstract
The utility model provides a buffering prestressed anchorage cable, including sleeve, spring, tool to lock, tray, anchor rope, the spring setting is installed on the tray in the sleeve, is equipped with tool to lock and tray at telescopic afterbody, and the tool to lock is installed in the tray lower part. The spring is directly installed on the tray and buffers the sleeve through the spring. The anchor rope can produce certain displacement in the sleeve, plays certain cushioning effect to the impulsive force, has improved the shock resistance of anchor rope, has prolonged the life of anchor rope, reduces the destruction degree to the country rock, has increased constructor's safety guarantee, has improved the security of engineering.
Description
Technical Field
The utility model relates to an anchor supporting facility, in particular to buffering prestressed anchorage cable.
Background
At present, various anchor cables are used in a large number in projects such as mine roadway support, road tunnel support, water conservancy culvert support, mountain body reinforcement, building pile foundation reinforcement and the like, and play a role in reinforcing surrounding rocks, so that the strength of the surrounding rocks bearing pressure is improved, and the method is an active support form. When the anchor cable is locked, the anchor cable is easy to slip, so that support accidents are caused. Therefore, the buffering prestressed anchor cable not only can have a good anchoring effect, but also can reduce the impact force on the anchor cable, when the buffering prestressed anchor cable is impacted by a load, the spring can generate great deformation, the time from the great deformation to the collapse of the surrounding rock is prolonged, the safety of constructors is ensured, and the probability of engineering accidents is reduced.
SUMMERY OF THE UTILITY MODEL
In order to overcome the not enough defect of current anchor rope impact force performance, the utility model provides a buffering prestressed anchorage cable, this anchor rope simple structure has powerful anchor power, has played fine cushioning effect to the impact force that receives moreover.
The utility model adopts the following technical proposal:
the utility model provides a buffering prestressed anchorage cable, including sleeve (1), spring (2), tool to lock (3), tray (4), anchor rope (5), spring (2) set up in sleeve (1), install on tray (4), are equipped with tool to lock (3) and tray (4) at the afterbody of sleeve (1), and tool to lock (3) are installed in tray (4) lower part.
Preferably, the spring (2) is directly arranged on the tray (4), and the spring (2) is pressed by the tray (4) to buffer the impact force of the anchor cable (5).
Preferably, a lock is arranged at the lower part of the tray (4), and the fastening degree can be adjusted by rotating the lock (3).
The utility model has the advantages that: (1) the spring (3) is arranged in the buffering prestressed anchor cable, so that the impact force of the anchor cable can be reduced, the shock resistance of the anchor cable is improved, and the service life of the anchor cable is prolonged. (2) When the anchor cable is subjected to impact force. The buffer action that spring (3) brought can reduce the degree of damage to the country rock, has increased constructor's safety guarantee, has improved the security of engineering.
Drawings
FIG. 1 is a sectional view of a prestressed buffer anchor cable.
Wherein, 1 sleeve, 2 springs, 3 tool to lock, 4 trays, 5 anchor ropes.
Detailed Description
The utility model is described in detail with the following figures:
the utility model provides a buffering prestressed anchorage cable, includes sleeve 1, spring 2, tool to lock 3, tray 4, anchor rope 5, and spring 2 sets up in sleeve 1, is equipped with tool to lock 3 and tray 4 at sleeve 1's afterbody. Spring 2 direct mount is on tray 4, and spring 2's intensity is great, and when the device received the impact force, spring 2 played the effect of buffering impact force. The lower part of the tray 4 is provided with a lockset 3, and the fastening degree can be adjusted by rotating the lockset 3.
The utility model relates to a buffering prestressed anchorage cable when the engineering uses, if strut the great deformation of country rock and appear suddenly or because when the earthquake produced the impact force, anchor rope 5 implemented certain pressure to spring 2 under the effect of impact force, and spring 2's elasticity makes and does not take place too big deformation when receiving the impact force, has striven for certain time of fleing for the site work, has played anti-shock, jar-proof effect.
Of course, the above description is not intended to limit the present invention, and the present invention is not limited to the above examples, and the changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present invention should also belong to the protection scope of the present invention.
Claims (3)
