Abstract
The utility model discloses an extendable anchor rod which is composed of an anchor rod body, a pallet and an end nut, wherein an expansion pipe and a resistance-increasing pipe are sleeved at the rear end of the anchor rod body, a hoop is arranged on the expansion pipe, the expansion pipe is fastened on the anchor rod body by the hoop, the pallet is installed in front of the hoop, the resistance-increasing pipe is a hollow steel pipe, a tip is arranged at the front end of the resistance-increasing pipe, and the top end of the tip is inserted into the tail end of the expansion pipe; the expansion pipe is a hollow circular steel pipe with a fissure along the longitudinal direction, and a convex shoulder is arranged at the rear end of the hollow circular pipe. When the extendable anchor rod is used for supporting, one end of the expansion pipe is fixed with a hoop ring; when the tunnel is deformed and the pallet is under stress, the stress is transferred to the expansion pipe through the shroud ring, and then the expansion pipe transfers the stress by the frictional force between the expansion pipe and the resistance-increasing pipe; after the frictional force reaches a certain value, the sliding motion is caused between the expansion pipe and the resistance-increasing pipe, and the contact area and the resistance between the expansion pipe and the resistance-increasing pipe are increased. Therefore, the purpose of extending the working section of the rod body is achieved.
Description
Technical field
The utility model relates to the anchor pole that colliery tunnel support is used.
Background technology
At present, general anchor pole all is made up of anchor bar body, pallet and termination nut.During use, the anchor bar body front end is anchored at foot of hole, and the anchor bar body rear end is fixed tightly on the scar of hell by pallet and termination nut.In coal-mine soft-rock roadway excavation engineering, when the rock mass loose and soft surrounding rock is out of shape, cause anchor pole " to be absorbed in " in the country rock, therefore, be sought after a kind of anchor pole that can extend with surrouding rock deformation.
Summary of the invention
For overcoming the above-mentioned deficiency of existing anchor pole, the utility model designs a kind of extending anchor pole.
A kind of extending anchor pole is made up of anchor bar body, pallet and termination nut, it is characterized in that, the rear end of anchor bar body is with one section pipe and increase resistance pipe of rising, and the pipe that rises is provided with the hoop cover, and the hoop cover pipe that will rise is prohibited admittedly on anchor bar body, and pallet is installed in the front of hoop cover, wherein:
Described increasing hinders the Guan Weiyi hollow steel pipe, and front end has tip, and the pipe afterbody that rises is inserted on the tip top, and when surrouding rock deformation, anchor pole stretches, and provides the anchor resistance by the frictional force that increases the resistance pipe and the pipe that rises;
The described pipe that rises is the steel hollow circular-tube that longitudinally has the slit, and the hollow circular-tube rear end is provided with convex shoulder.The effect of convex shoulder is to be used to block the hoop cover, prevents that hoop from overlapping.
During installation, earlier the body of rod is anchored to the boring projected depth, stop protruded length, tray, and be close to scar will bind round cover then and rise by pipe box on the body of rod, put to increase the resistance pipe, and the termination nut of screwing at last makes to increase and hinders pipe and tighten, and installs.
The utility model advantage is: during supporting, garter spring is fixed the Guan Yiduan that rises, pass to the pipe that rises with the stressed back of roadway deformation pallet by garter spring, rise pipe by and increase the frictional force of resistance between pipe and transmit power, frictional force reaches to rise behind the certain value to produce between the Guan Yuzeng resistance pipe slides, strengthen with increasing resistance pipe contact area simultaneously, resistance increases.So just reached the purpose of body of rod active section elongation.
Description of drawings
Fig. 1 is structure of the present utility model and installs and uses state diagram.
Marginal data, the 1-anchor bar body, the 2-pallet, 3-binds round cover, and the 4-pipe that rises, 5-increase the resistance pipe, 6-termination nut, 7-boring, 8-scar.
The specific embodiment
The utility model is constructed and is installed and used state as shown in Figure 1, it is made up of anchor bar body 1, pallet 2 and termination nut 6, the rear end of anchor bar body 1 is with one section pipe 4 that rises and hinders pipe 5 with increasing, the pipe 4 that rises is provided with hoop cover 3, hoop cover 3 pipe 4 that will rise is fastened on the anchor bar body 1, pallet 2 is installed in the front of hoop cover 3, wherein:
Described to increase resistance pipe 5 be a hollow steel pipe, and front end has tip, and pipe 4 afterbodys that rise are inserted on the tip top;
The described pipe 4 that rises is hollow circular-tubes of being made by the toughness steel and longitudinally have the slit, and the hollow circular-tube rear end is provided with convex shoulder, and the effect of convex shoulder is to be used to block hoop cover 3, prevents that hoop from overlapping 3 and deviating from.
During installation, earlier anchor bar body 1 is anchored to boring 7 projected depths, stop protruded length, tray 2, and be close to scar 8 will bind round cover 3 then and the pipe 4 that rises is enclosed within on the anchor bar body 1, put to increase resistance pipe 5, and the termination nut 6 of screwing at last makes to increase resistance and manage 5 and tighten, and installs.
