Description
Technical field
The present invention relates to mine working engineering apparatus field, more particularly to a kind of anchor pole packing ring changed colour at various pressures
And its application method.
Background technology
Anchor pole is the body of rod that a kind of tensile strength is better than rock-soil layer, and its one end inside rock-soil layer with being mutually bonded to form friction
Resistance, the other end is exposed to be applied pulling force to the body of rod by mounting gasket, pallet and nut outside and passes the pulling force at anchor pole head
To the region of anchoring body, its function is to apply prestressing force to anchor pole.
Anchor cable is to be fixed on tunnel surface by outer end, and the other end is fixed in the deep rock mass of roadway surrounding rock through sliding
The prestress wire in face.Backing plate is one piece of metallic plate being close to tunnel surface, has circular hole to pass through for anchor cable above.Backing plate with
Packing ring is installed between lockset.
Anchor pole is with anchor cable as the important apparatus of reinforced roadway country rock, and its stress is for weighing its working stability situation
Have great importance, therefore numerous anchor poles（Rope）Dynamometer is developed.
At present, using more universal anchor ergometer by handlance, jack, sensor and common group of digital displaying meter
Into although this method can accurately measure pulling force suffered by anchor pole, it has three substantially deficiencies：One is that its installation procedure is answered
Miscellaneous, the installation of the anchor ergometer needs special messenger and is responsible for and is operated according to strict program, the more manpower of consuming and when
Between；Two be that it produces certain influence to suspension roof support not as a part for suspension roof support itself part, is especially limited
The linear deformation of anchor pole and then limit country rock and produce appropriate deformation, because country rock can not produce appropriate deformation and can not possibly be effective
The certain stress of release, this surrouding rock stress persistently increases to constitute a serious threat to surrounding rock stability；3rd involves great expense, each
Individual anchor ergometer is ten times of a common bolt or so, and the decades of times of the supporting even more anchor pole of installing instruments, so high
Can not possibly all supporting installation of whole anchor pole in its engineer applied of high price decision.Which limits to all anchors in engineer applied
Effective monitoring of bar and then effective monitoring of restricted area surrouding rock stress change.
The content of the invention
To solve the above-mentioned technical problem that prior art is present, the invention provides one kind country rock can be allowed to produce appropriate become
Shape and can be different according to rockbolt stress, the anchor pole packing ring and its application method changed colour at various pressures is equally applicable to anchor cable.
The present invention solve above-mentioned technical problem technical scheme be：A kind of anchor pole packing ring changed colour at various pressures, bag
Washer body is included, and shows the indicator lamp of rockbolt stress state；The washer body is made up of inner box and outer box, the outer box
Center be provided with axial body, box bottom is arranged with a pair of firm springs；Battery and multiple differences are provided with the outer box
A kind of indicator lamp of color, indicator lamp of color represents one-level by force intensity, and battery is powered for indicator lamp, the circuit of each indicator lamp
On be respectively connected with electrode film and negative electrode plate, positive, negative electrode plate, in released state is flush-mounted in outer box inwall；It is same to refer to
Show the positive, negative electrode plate of lamp, positioned at same level；The electrode slice along outer box method order set, adjacent two-stage electrode slice it
Between leave gap；The center of the inner box is provided with axial body, and cassette bottom face sets spring base, and the outer wall of inner box is provided with a circle metal
Guide card；When inner box and outer box are installed, the axial body of inner box and outer box, grafting form anchor pole passage, and firm spring correspondence is pacified
Loaded in spring base, metallic laminas and positive, negative electrode plate, in contactless state；When packing ring stress, firm spring-compressed is interior
Box and outer box are moved towards, with the increase of pressure, metallic laminas successively with positive, negative electrode plates at different levels, be connected, representative is accordingly pressed
The indicator lamp of power lights.
It is described per one-level positive, negative electrode plate, distance of stretch out and draw back of the width correspondence per first class pressure intensity lower spring, adjacent two
Less gap is left between level electrode slice, the width of the metallic laminas is slightly larger than the width in gap.
The rockbolt stress intensity is divided into Soil Anchor Design pretightning force, three ranks of yield strength and ultimate strength, described firm
The stroke of strong spring is with Soil Anchor Design pretightning force, yield strength and ultimate strength by checking：Under original state, anchor pole not by
Power, spring is in normal condition, metallic laminas and positive, negative electrode plate, in contactless state；When rockbolt stress is anchor pole pretension
During power design strength, the distance of stretch out and draw back of spring be metallic laminas to first order positive, negative electrode plate, distance；When rockbolt stress is
During anchor pole yield strength, the distance of stretch out and draw back of spring be first order positive, negative electrode plate, to second level positive, negative electrode plate, distance；
When rockbolt stress is anchor rod ultimate intensity, the distance of stretch out and draw back of spring is second level positive, negative electrode plate, to the positive and negative electricity of the third level
Pole piece, distance.
The indicator lamp is LED, is arranged to green, yellow, red three kinds of colors, and green LED lamp is bright to represent that rockbolt stress is to set
Pretightning force level is counted, yellow LED lamp represents that rockbolt stress is its yield strength level, and red LED lamp is bright to represent that rockbolt stress is
Its ultimate strength level.
The battery case for being used for installing battery is provided with the outer box, and for fixing the spring base of firm spring.
The circuit lead of the indicator lamp be copper conductor, positive, negative electrode plate, be copper material.
The inner box and outer box are made using high-strength transparence material.
A kind of anchor pole packing ring and its installation and application changed colour at various pressures, its step is：
1）Spudded in using the rock drill, drilling rod and drill bit that are mutually equipped with anchor pole inside country rock drilling；
2）Drilling is cleaned up, Anchor Agent powder stick drilling bottom is put into, then anchor cable is put into drilling；
3）The anchor pole packing ring and nut loaded onto pallet successively in anchor pole convex exposure end, changed colour at various pressures；After installing, tighten
Nut and the pretightning force for being applied to setting, the pretightning force applied are lighted to the indicator lamp for representing its state just, i.e., packing ring can
Intuitively it is shown to up to design pretightning force size.
The beneficial effects of the invention are as follows：The anchor pole of changeable colour under different pressures（Rope）The inner box of packing ring and outer box have drawn from height
The transparent material of intensity, it is safe and reliable；And show different color with being in anchor pole under different pressures state（Green, yellow,
It is red）Soil Anchor Design prestressing force, yield stress, three kinds of levels of limit stress are corresponded to respectively, to distinguish that rockbolt stress state is provided
Powerful technique is supported；The packing ring surrouding rock deformation certain due to that can also be realized by spring deforms and overcomes conventional anchor survey
Power meter can not allow country rock to produce the defect that controllable deforming discharges certain stress；Cheap, design cost is the half of anchor pole.
