Key is exactly the problem of anchor cable elongation percentage, and the change of anchor cable when roadway support intensity cannot meet supporting requirement, usually occurs
Not enough, anchor cable head or anchor pole head are pressed down, press the phenomenon for collapsing shape amount.Chinese patent (application number：201520943821.9)：It is a kind of
New Anchor Cable anchor pole is anti-collapses device, using rubber strip and S-hook, simple and convenient effective to have contained that rigging collapses；China
Patent (application number：201520953880.4)：Anchor cable fixing device, there is provided anchor cable is quick when one kind can realize that anchor hole is deeper
The anchor cable fixing device of anchoring operation；Chinese patent (application number：201420842376.2)：Small distance anchor cable fixing device, makes
Neighbouring anchor pole or anchor cable are connected to an entirety, using rear expansion anchor pole and anchor cable stressed zone scope, while can be
The deformation of country rock and early warning and time enough and deformation space are provided to press.
But above-mentioned prior art but seldom improves the elongation percentage of anchor cable on the securing means, adapts to rushing for roadway surrounding rock
Load and large deformation are hit, so needing to be improved existing fixing device.
Utility model content
For the deficiencies in the prior art, this utility model allows pressure fixing device there is provided a kind of anchor cable so that anchor cable has
The ability of opposing country rock impact load and suitable for surrounding rock deformation, can provide enough deformation spaces and to press for anchor cable well
The time of early warning.
To realize object above, this utility model is achieved by the following technical programs：
A kind of anchor cable allows pressure fixing device, including steel supporting plate, allows pressed wood supporting plate, steel lifts plate, nut and anchor cable, described
Steel supporting plate, pressed wood supporting plate and steel lifts plate is allowed to have an installing hole of the anchor cable, the anchor cable passes through the steel respectively
Supporting plate, allow pressed wood supporting plate and the installing hole of steel lifts plate to squeeze into inside country rock, and the anchor cable is fixedly mounted with the nut.
Further, the specification of the steel supporting plate, a length of 200～250mm, a width of 120～200mm, a height of 15～20mm,
The specification for allowing pressed wood supporting plate, a length of 200～250mm, a width of 120～200mm, a height of 50～80mm, the pressed wood support that allows
The effect of plate is the elongation percentage for improving the anchor cable, to play a part of to resist country rock impact load and suitable for surrounding rock deformation,
Which highly can be adjusted according to the size of rock deformation.
Further, the steel lifts plate is channel-section steel or steel plate, and the length of the channel-section steel is 1000～2000mm, described
The specification of steel plate, a length of 250～300mm, a width of 250～300mm, a height of 10～20mm.
This utility model allows pressure fixing device there is provided a kind of anchor cable, anchor cable respectively by steel supporting plate, allow pressed wood supporting plate and
Steel lifts plate is squeezed into inside country rock, and is fixedly mounted with nut, allows the setting of pressed wood supporting plate to improve the elongation percentage of anchor cable, is risen
Arrived opposing country rock impact load and suitable for surrounding rock deformation effect, can for anchor cable provide enough deformation spaces with it is pre- to press
The alert time.
