Description
Technical field
The utility model relates to engineering safety technical field, relates to a kind of engineering anchor cable, particularly a kind of anti-section anchor cable preventing being truncated in work progress.
Background technology
Along with the increase of coal mining depth and complex geologic conditions degree, soft rock roadway support more and more adds difficulty.In recent years, cable bolting is used widely in the mining developed country such as Britain, Australia, and cable bolting technical development is rapid, particularly in slope treatment, traffic tunnel, water power water conservancy, military project, building foundation pit etc.China introduces this technology from the sixties in last century, introduces in the roadway support engineering of colliery subsequently, and according to incompletely statistics, the permanent anchor cable in China's coal-mine tunnel is more than 1,000,000, and annual new construction anchor cable hundreds of thousands root.Anchor cable is as concealed work, and constructor uses inferior materials and turns out substandard goods and happens occasionally, and these engineerings are become " time bomb ".In recent years, domestic and international expert, to this has been a large amount of nondestructive testing research, but even to this day, does not still have the anchorage cable anchoring quality detection technology that practicality is strong, therefore researches and develops that novel anti-to cut anchor cable and application thereof be extremely important and very significant.
Utility model content
For the problems referred to above, the purpose of this utility model is to provide one and prevents from being truncated in construction, and if be truncated, the anti-section anchor cable that can display.
The utility model is achieved through the following technical solutions: a kind of anti-section anchor cable, and the non-bending steel cable be made up of many steel wires forms, and comprises outer silk and internal layer silk; One or a few in the central hair of internal layer silk adopts the foraminate hollow steel wire of center band, and inserts elastic strip in aperture, and makes it be in tensioning state; The two ends of described elastic strip are respectively connected with for making position at elastic strip in the stopping means of tensioning state.
A kind of mode, stopping means can be only the limited block be connected with elastic strip, and its volume is greater than the aperture of hollow steel wire.
Another kind of mode; the structure of described stopping means is; limited block is fixed with respectively at the two ends of elastic strip; described limited block has been threaded end cap; the inner end of end cap is provided with Compress Spring; the outside of end cap is provided with protection chamber, and protection chamber and anchor cable are connected, and protection chamber is provided with the hole that end cap can be made to pass through smoothly.The effect of protection limited block is played in protection chamber, prevents limited block damage in the course of work, affects result of use.
After stopping means is installed, end cap sinks into protect in the hole in chamber, prevents end cap from protruding from outside protection chamber, affects the use of anchor cable; One end of described Compress Spring is connected with end cap, and the other end is butted on the end face of anchor cable.
Described limited block and elastic strip seccotine bond.
Described end cap is rubber cap or plastic cap or other similar items.
Described elastic strip is rubber strip.
The beneficial effects of the utility model are: a kind of anti-section anchor cable, and operation is simple, and easy to process, material source is wide; If anchor cable is truncated, the superfine elastic strip being connected to two end cap places is just in doughy state, namely shows anchor cable and is in the state of blocking; After anchor cable is truncated, it is inner that rubber bar shrinks the anchor cable after blocking, and cannot pull out from truncated position, no matter be all can judge whether anchor cable is cut from truncated position or anchor cable end, anti-ability of playing tricks is strong.

In figure, 1. outer silk, 2. internal layer silk, 3. elastic strip, 4. stopping means, 4-1. limited block, 4-2. end cap, 4-3. Compress Spring, 4-4. protects chamber, 4-5. hole.
Detailed description of the invention
In the accompanying drawings, a kind of anti-section anchor cable, the non-bending steel cable be made up of many steel wires forms, and comprises outer silk 1 and internal layer silk 2; One or a few in the central hair of internal layer silk 2 adopts the foraminate hollow steel wire of center band, and in aperture, insert elastic strip 3, and makes it be in tensioning state; The two ends of described elastic strip 3 are respectively connected with the stopping means 4 for making elastic strip 3 be in tensioning state.
A kind of mode, stopping means 4 can be only the limited block 4-1 be connected with elastic strip 3, and its volume is greater than the aperture of hollow steel wire.
Another kind of mode; the structure of described stopping means 4 is; limited block 4-1 is fixed with respectively at the two ends of elastic strip 3; described limited block 4-1's end cap 4-2 has been threaded; the inner end of end cap 4-2 is provided with Compress Spring 4-3; the outside of end cap 4-2 is provided with protection chamber 4-4, and protection chamber 4-4 and anchor cable are connected, and protection chamber 4-4 is provided with the hole 4-5 that end cap 4-2 can be made to pass through smoothly.Protection chamber 4-4 plays the effect of protection limited block 4-1, prevents limited block 4-1 in the course of work from damaging, affects result of use.
After stopping means 4 is installed, end cap 4-2 sinks into protect in the hole 4-5 of chamber 4-4, prevents end cap 4-2 from protruding from outside protection chamber 4-4, affects the use of anchor cable; One end of described Compress Spring 4-3 is connected with end cap, and the other end is butted on the end face of anchor cable.
Described limited block 4-1 and elastic strip 3 bond with seccotine.
Described end cap 4-2 is rubber cap or plastic cap or other similar items.
Described elastic strip 3 is rubber strip.
Embodiment one (by reference to the accompanying drawings 1), in construction process, needs special tool because anchor cable blocks, and disposable all silks is all blocked, and so elastic strip 3 also will be truncated.When stopping means 4 is only limited block 4-1, when anchor cable blocks, the elastic strip 3 of truncated position just can shrink in internal layer silk 2 at once, and the elastic strip 3 being positioned at former end is in doughy state, limited block 4-1 slip anchor is sagging, namely can judge whether anchor cable is in the state of blocking easily.
Embodiment two (by reference to the accompanying drawings 2); when stopping means 4 comprises limited block 4-1, end cap 4-2, Compress Spring 4-3 and protection chamber 4-4; when anchor cable blocks; the elastic strip 3 of truncated position just can shrink in internal layer silk 2 at once; because limited block 4-1 and end cap 4-2 links into an integrated entity, when after the pulling force lacking elastic strip 3, under the effect of Compress Spring 4-3; limited block 4-1 ejects from the hole 4-5 of protection chamber 4-4, can judge whether anchor cable is in the state of blocking easily.
