Abstract
A kind of recyclable pressure-relieving achor bar that the utility model is provided, including anchor bar body, nut, metal washer, rubber bush, brute spring, pallet, support and fixed anchor head.The brute spring is enclosed on the top of anchor bar body, between pallet and metal washer, and the outside of packing ring applies prestressing force by nut.The brute spring outer cover rubber sleeve cylinder, can play a part of protecting spring, lower nut can be directly unloaded when reclaiming spring, reclaim spring and sleeve is reused.Wherein anchor pole end is the bigger fixation anchor head of diameter, and fixed anchor head is connected through a screw thread with anchor pole.Fixed anchor head afterbody has four supports, plays a part of increasing anchor force, anchor pole is not drawn out easily.When moderate finite deformation occurs for country rock, anchor pole end is fixed in the presence of fixed anchor head and strut, and brute spring compressive deformation is realized to allow and is pressed into and protects anchor pole from breaking.
Description
Technical field
The utility model is related to a kind of anchor pole, and in particular to a kind of recyclable, makes pressure effect good, can absorb country rock strain
The pressure-relieving achor bar of energy.
Background technology
In recent years, with the depleted of superficial part coal resources, the mining depth of coal is continued to increase, and is formd and is adopted greatly
Deep, highland pressure, thump, the situation of complicated mining conditions.Traditional rigid anchor pole is under this geological environment, usually because fast
Failure is broken in fast or violent deformation, it is difficult to play due support action.Rigidity will result in greatly that elongation percentage is relatively low, and this is also
Why common bolt can not adapt to the heavily stressed key reason of deep-well.In addition, most of anchor pole is only using once, this gives coal
Ore deposit brings certain economic loss and the wasting of resources.
The content of the invention
Relatively low in order to solve common bolt elongation percentage in the prior art, anchor pole is easily pulled off and irretrievable problem,
The utility model provides a kind of recyclable pressure-relieving achor bar.
A kind of recyclable pressure-relieving achor bar, including anchor bar body, nut, metal washer, rubber bush, brute spring, pallet, support
Frame and fixed anchor head.Described brute spring internal diameter is slightly larger than anchor bar body, is directly sleeved on anchor bar body, positioned at pallet and metal gasket
Between circle and brute spring outer cover rubber sleeve cylinder.Metal washer rear portion abuts nut, and anchor pole end is provided with fixed anchor head,
It is connected through a screw thread with anchor bar body.The fixed anchor head is provided with support, is fixed on by way of welding on anchor head.
The utility model compared with prior art, has the advantages that：
A kind of above-mentioned recyclable pressure-relieving achor bar using brute spring as pressure device is allowed, when country rock occurs acutely rapidly to become
During shape, spring stress compression deforms, and absorbs the energy of outside surrouding rock deformation, the kinetic energy of outside surrouding rock deformation is changed into
Elastic potential energy, plays a part of protecting anchor rod body；While brute spring outer cover rubber sleeve cylinder, can be by under spring and mine
Wet environment isolation, spring corrosion is effectively prevented, beneficial to recovery；The anchor pole end has the device for strengthening anchoring, fixed
Anchor head internal diameter is bigger, is connected by screw thread with anchor pole, and anchor head afterbody is provided with support, when anchor pole is by outside pulling force, support
Drilling palisades will be blocked, prevent anchor pole from sliding, increase the anchor force of anchor pole.
Brief description of the drawings
The utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is principle schematic diagram of the present utility model.
Fig. 2 is the stereogram of rubber bush 4.
Fig. 3 is the stereogram of fixed anchor head 8.
In Fig. 1,2,3,1 anchor bar body, 2 nuts, 3 metal washers, 4 rubber bush, 5 brute springs, 6 pallets, 7 supports, 8 are consolidated
Determine anchor head
Embodiment
The utility model is described in detail with reference to Fig. 1.
A kind of recyclable pressure-relieving achor bar, including 1 anchor bar body, 2 nuts, 3 metal washers, 4 rubber bush, 5 brute springs, 6
Anchor head is fixed in pallet, 7 supports and 8.Fixed anchor head 8 is connected with anchor bar body 1 first when equipment is installed, then by the brill in drilling
Bits and rubble clean out, be put into after resin explosive roll and anchor anchor bar body 1 in the borehole, then by a pallet 6, brute spring 5,
Rubber bush 4, metal washer 3 are inserted in the afterbody of anchor bar body 1 respectively, are finally fastened and fixed the body of rod 1 with nut 2, make each part
It is in close contact and pallet 6 is close to country rock, last tension to regulation pretightning force.
When acutely rapidly deformation occurs for country rock, anchor bar body 1 is by the pulling force towards lane space, in Anchor Agent, support
Anchor pole end is fixed in the presence of frame 7 and fixed anchor head 8, provides larger anchor force for anchor pole, now the stress of brute spring 5
Compression realization allows pressure；When anchor pole, which completes support work, to be reclaimed, nut 2 is unloaded into taking-up brute spring 5 and rubber bush 4
Complete to reclaim.
