Abstract
The utility model relates to an anchor shank stress stochastic detector. The utility model is used for mines, tunnels and other projects, which use an anchor shank for support and protection. The utility model is composed of a hydraulic cylinder 5, a manual hydraulic pump 8, a pressure gauge 7, a pipeline 6, a pressure transducer 9, a force indicator 10 and a signal trigger mechanism 4. The signal trigger mechanism is connected with the cushion ring 3 of the end of the anchor shank; the signal trigger mechanism is arranged between the end of the anchor shank and the hydraulic cylinder 5; the signal trigger mechanism can rotate with the cushion ring 3 and send out electrical signals. When used, the detector does need not to be installed in advance and does not need a purpose made anchor rod. The utility model can realize the stochastic detection of any common anchor shank in the process of actual use.
Description
The utility model is the stressed detector at random of a kind of anchor pole, can be applicable to adopt mine, tunnel and other engineering of bolt supporting.
For detect anchor pole when reality is used force-bearing situation and the performance index of anchor pole, developed multiple anchor ergometer both at home and abroad.Introduced ML-20 type axis force of anchor meter in " bolt-spray support " book as Coal Industry Press's publication in 1989.This tautness meter is by hand oil pump, hollow lifting jack, and tensimeter and pipeline are formed.Hollow lifting jack central shaft is connected with anchor pole, is fixed in the anchor pole end, comes anchor pole is applied pulling force by fluid injection in hollow lifting jack, and then measures the maximum pull that anchor pole can bear, the i.e. maximum anchor force of anchor pole.The weak point of this instrument is, can only measure the maximum anchor force of anchor pole, and can not detect anchor pole force-bearing situation in use.Coal Industry Press 1993 publish " the KS-4 type anchor ergometer of coal mine support handbook introduction is that the hydraulic pressure sincere feeling that adopts to be installed in the anchor pole end is in advance transmitted the power that anchor pole bears.The Raymond anchor ergometer that the research report R19336 of United States Bureau of Mines (USBM) introduces is to utilize the pulse-echo systems measures signal to determine the stressing conditions of anchor pole by the time of anchor pole.The weak point of the stressed detector of these anchor poles is, needs to install on tested anchor pole in advance the component of instrument when measuring, and maybe can only adopt special anchor pole as measuring anchor pole.And can not realize to common bolt in use with machine testing.
The purpose of this utility model is to overcome the deficiency on the above-mentioned prior art, provides a kind of and need not prior installation and can the common bolt in using be carried out with the stressed detector at random of the anchor pole of machine testing.
The purpose of this utility model can reach by following measure:
The utility model comprises hydraulic cylinder, hydraulic hand-pump, tensimeter, signal trigger mechanism, pressure transducer and power indicator.Signal trigger mechanism is installed between anchor pole end and the hydraulic cylinder, and is connected with the packing ring of anchor pole end, can be with its loosening electric signal that sends.Connect the electric signal input power indicator of pressure transducer between hydraulic cylinder, hydraulic hand-pump, tensimeter and the pressure transducer by pipeline.
The purpose of this utility model can also reach by following measure:
Signal trigger mechanism has supporting base, rotating cylinder, plays the compression spring of axial adjustment effect.Supporting base is fixed between anchor pole pallet and the hydraulic cylinder.Rotating cylinder is connected with the packing ring of anchor pole end, by spring top clamping.Between rotating cylinder and supporting base, extension spring is arranged.Switch is installed on supporting base, and switch is connected with luminous or sounding component.Contact is arranged on the rotating cylinder.This contact contacts with switch and disconnects at the initial sum final position respectively.
The drawing of accompanying drawing is described as follows:
Fig. 1 is an embodiment of the present utility model.
Fig. 2 is the front view of signal trigger mechanism.
Fig. 3 is the vertical view of Fig. 2.
Fig. 4 is the front view of rotating cylinder.
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1 and Fig. 2.The 1-anchor pole, 2-anchor pole pallet, 3-packing ring, 4-signal trigger mechanism, 5-hydraulic cylinder, 8-hydraulic hand-pump, 7-tensimeter, 9-pressure transducer, 10-power indicator.Between hydraulic cylinder, hydraulic hand-pump, pressure transducer, there is pipeline 6 to be connected to each other.One end of the extension rod 15 in the hydraulic cylinder is connected with anchor pole, and the other end is fixed hydraulic cylinder and signal trigger mechanism with threaded fastener.
Referring to Fig. 2～Fig. 4.Signal trigger mechanism has supporting base 12, rotating cylinder 13, spring 14.Supporting base is connected on the last installed surface of hydraulic cylinder.There is fixture block 21 to be stuck on the outer rim of packing ring 3 on the rotating cylinder.Spring 14 is installed between rotating cylinder and the hydraulic cylinder installed surface, regulates the axial location of rotating cylinder, and rotating cylinder fixture block and packing ring 3 outer rims are kept in touch.One end of spring 18 is fixed on the rotating cylinder, and the other end is fixed on the supporting base 12 by bearing pin 16.Contact 17 is arranged on rotating cylinder.Switch 19 is installed on the supporting base.Switch 19 is connected with pilot lamp 11, and pilot lamp is fixed on the panel of power indicator.
Power indicator among Fig. 1 has digital display screen, shows the anchor pole stress value.
After during use the fixture block on the rotating cylinder 13 21 being stuck in the outer rim of packing ring 3, rotary branching holder 12 makes contact 17 contact-making switches 19, and the edge lamp bright (expression is installed appropriate) in this moment pilot lamp 11 is fixed supporting base.Handle hydraulic hand-pump, to the hydraulic cylinder feed flow.The terminal suffered downward power of anchor pole this moment is the pulling force sum that nut fastening force and hydraulic cylinder award.When the value of thrust that awards when hydraulic cylinder equaled the anchor force of anchor rod anchored end, the nut fastening force equalled zero, and packing ring 3 is loosening, and this moment, rotating cylinder 13 began to rotate (backing pin 20 limits its turned positions) under the effect of extension spring 18.Contact 17 is bright with the red light that switch 19 breaks away from the rear indicator light 11, and be value of thrust that anchor pole when working condition born from power indicator 10 values of reading this moment.
The utility model compared with prior art has the following advantages:
This rockbolt stress detector need not prior installation when using, and also need not special anchor pole, can realize to arbitrary common bolt in actual use with machine testing.
