Abstract
The utility model provides a dock long stock with cross rib, includes the body of rod, the body of rod comprises the first pole that is located the front end, the foot piece that is located the one or more middle part pole at middle part and is located the rear end, between first pole and the middle part pole, between middle part pole and the foot piece, all through can the dismantlement mode connecting. A dock long stock with cross rib which the percentage elongation is big, and disrumpent feelings rate is low, and the anchor scope is big, and anchoring effect is good, and stirring moment of torsion resistance is little, stirring effect good, and body of rod tensile strength is high, dismantles simple to operate, and adaptable deep well is heavily stressed, soft rock roadway support, can continuously provide supporting load, prevents that the country rock from becoming flexible the inbreak, struts effectually. And the stock among the prior art, length receives the restriction, and the anchor rope percentage elongation is lower simultaneously, and disrumpent feelings rate is great.
Description
Technical field
The utility model belongs to deep mining technical field, particularly relate to a kind of with cross rib to spreading anchor pole.
Background technology
Along with China's superficial part coal resources are fewer and feweri, many mines enter deep mining, cause roadway maintenance difficulty.High stress tunnel, soft-rock tunnel, deformation of the surrounding rock in tunnel large by the back deflection such as tunnel of mining influence destroy serious, the phenomenons such as common bolt fastening invalidation, anchor shaft anchor cable are disrumpent feelings are serious, and by drift section size impact, regular screw threads steel anchor rod length is restricted, and anchor cable elongation per unit length is lower, disrumpent feelings rate is larger.Ripe roadway bolting support technology is in shallow mining tunnel extensive use, but for deep high stress tunnel, its anchor pole still disrumpent feelings inefficacy can occur.Most to spreading anchor pole, the body of rod is without cross rib, and Anchor Agent mixing effect is poor, and Anchor Agent is combined closely knit not with anchor pole, even cavitation appears in anchoring section many places, and pulling capacity is large not.
Utility model content
Restricted and to the problem of spreading anchor pole without cross rib in order to solve rock-bolt length in prior art, the utility model provide a kind of with cross rib to spreading anchor pole.
With cross rib to a spreading anchor pole, comprise the body of rod, the described body of rod is by being positioned at the first bar of front end, the one or more middle parts bar being positioned at middle part and the foot piece that is positioned at rear end forms.Between described first bar and middle part bar, between middle part bar and foot piece, all connected by removably.
Preferably, the lower end of first bar, the two ends of middle part bar and the upper end of foot piece are all connected with linkage section, have screwed hole in linkage section; Between first bar and middle part bar, between middle part bar and foot piece, the stud all by inserting screwed hole is connected.
Preferably, the diameter at linkage section place is greater than the diameter of first bar, middle part bar or foot piece.
Preferably, the body of rod is provided with cross rib, between the distance 25mm to 33mm between adjacent cross rib, the width of cross rib is between 5mm to 15mm, and the height of cross rib is between 0.5mm to 1.5mm.
Preferably, the distance between adjacent cross rib is 33mm, and the width of cross rib is 10mm, and the height of cross rib is 1.2mm.
Preferably, on stud, also cover has packing ring.
The utility model compared with prior art, has following beneficial effect:
Described in the utility model a kind of with cross rib to spreading anchor pole, its elongation per unit length is large, and disrumpent feelings rate is low, and anchoring scope is large, anchoring effect is good, stirring torque resistance is little, mixing effect good, and body of rod tensile strength is high, removes and installs conveniently, can adapt to that deep-well is heavily stressed, soft rock roadway support, can continue to provide Support Resistance, prevent wall rock loosening inbreak, supporting effect is good.And anchor pole of the prior art, length is restricted, and also has anchor cable elongation per unit length lower simultaneously, the problems such as disrumpent feelings rate is larger.

Detailed description of the invention
Below in conjunction with Fig. 1 to Fig. 5, the utility model is described in detail.
A kind of new molded breadth cross rib 4 spacing, to spreading anchor pole, comprises the body of rod 6, and the described body of rod 6 is by being positioned at the first bar of front end, the one or more middle parts bar being positioned at middle part and the foot piece that is positioned at rear end forms.The upper end of the first lower end of bar, the two ends of middle part bar and foot piece is all connected with linkage section 5, and the diameter at linkage section 5 place is greater than the diameter of first bar, middle part bar or foot piece.Screwed hole 8 is had in linkage section 5.Between first bar and middle part bar, between middle part bar and foot piece, the stud 3 all by inserting screwed hole 8 is connected, and on described, also cover has packing ring 7.
Further, the body of rod 6 is provided with cross rib 4, between the distance 25mm to 33mm between adjacent cross rib 4, the width of cross rib 4 is between 5mm to 15mm, and the height of cross rib 4 is between 0.5mm to 1.5mm.
Further, the distance between adjacent cross rib 4 is 33mm, and the width of cross rib 4 is 10mm, and the height of cross rib 4 is 1.2mm.
One described in the utility model new molded breadth cross rib 4 spacing is to spreading anchor pole, and the body of rod 6 is divided into multistage, convenient transport and use.User of service can also by regulating the middle part length of bar and the number of middle part bar, the entire length of adjustment anchor pole.
Certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned citing, the change that those skilled in the art make in essential scope of the present utility model, remodeling, interpolation or replacement, also should belong to protection domain of the present utility model.
