Abstract
The utility model discloses a tunnel safe running clearance measuring instrument which is composed of a bottom transverse pipe, a transverse scale, a vertical pipe and a vertical scale. The bottom transverse pipe is a square pipe whose length is greater than the gauge and less than the width of a tunnel, a pedestal positioning pin is arranged at the upper plane of the bottom transverse pipe, and two gauge positioning blocks are respectively welded at the two ends of the lower plane of the bottom transverse pipe; the transverse scale is a scaled square pipe which can be inserted into the bottom transverse pipe, after the transverse scale is inserted into the bottom transverse pipe, one end of the transverse scale is exposed, and an upward plug is arranged at the exposed end; the vertical pipe is a square pipe which can be inserted into the plug, and a vertical pipe positioning pin is arranged on the vertical pipe; and the vertical scale is a scaled square pipe which can be inserted into the vertical pipe. The instrument can rapidly and accurately measure the safe running clearance of tracks, and meet the requirement of safe transport.
Description
Technical field
The utility model relates to measuring instrument, relates in particular to the instrument of measuring mine down-hole haulage drift safe operation gap.
Background technology
Continuous extension along with pit mining, affected by goaf dynamic pressure, there is distortion in various degree in the tunnel of haulage vehicle, particularly when the larger gradient tunnel of deflection promotes, main equipment equipment such as () roadheader, coal machine, fully mechanized mining supporters is easily scraped lane side or is touched back, the geomantic omen pipeline of extruding in tunnel, cable etc., cause haulage vehicle to slide down and the generation of other accident, has very large transportation safety hidden danger.For fear of this phenomenon, occur, before promoting main equipment, should measure lateral clearance and down suction between track and protrusion position, tunnel.Also do not measure at present the measuring instrument in this gap.
Utility model content
In order to solve the measurement problem in track and gap, tunnel, the utility model provides a kind of tunnel safety running clearance measuring instrument, realizes and measures fast, accurately rail safety running clearance, reaches the requirement of transporting safely.
For achieving the above object, the technical scheme that the utility model is taked is:
A tunnel safety running clearance measuring instrument, is characterized in that, it is comprised of bottom transverse tube, horizontal staff, standpipe and vertical scale; Described bottom transverse tube is that a length is greater than the square tube that gauge is less than span length, and on the transverse tube of bottom, plane is provided with base register pin, and a gauge locating piece is respectively welded at transverse tube lower plane two ends, bottom; Described horizontal staff is to insert the square tube with scale of bottom in transverse tube, and after horizontal staff inserts bottom transverse tube, expose one end, exposes and on head, has plug upward; Described standpipe is the square tube that can insert on plug, and standpipe is provided with standpipe register pin; Described vertical scale is the square tube with scale that can insert in standpipe.
Above-mentioned transverse tube, horizontal staff, standpipe, vertical scale also can be pipe.
The method of utilizing above-mentioned measuring instrument to detect tunnel safety running clearance is as follows:
First by each assembling parts together, horizontal staff is inserted to transverse tube, with base register pin, fix, standpipe is inserted on plug, vertical scale is inserted in standpipe, with standpipe register pin, fix; During measurement, utilize gauge locating piece that transverse tube is snapped on track, unclamp base register pin, extract horizontal staff out, measure the breadth extreme that track needs to lane side, track behind location in extraction vertical scale measurement permission width range, to back gap, verifies according to main equipment entrucking full-size whether lifting vehicle can safe operation in tunnel.
The utility model is realized and is measured fast, accurately rail safety running clearance, reaches the requirement of transporting safely.The utility model adopts split-type structural, it is easy for installation to carry, measurement data is accurate; Saving personnel, during in-site measurement, one people can operate, and has improved work efficiency; Alleviate labor strength, there is good application value.
Accompanying drawing explanation
Fig. 1 is the utility model schematic diagram.
In figure: 1-bottom transverse tube, 2-horizontal staff, 3-standpipe, 4-vertical scale, 5-base register pin, 6-gauge locating piece, 7-plug, 8-standpipe register pin.
Embodiment
As shown in Figure 1, a kind of tunnel safety running clearance measuring instrument, it is comprised of bottom transverse tube 1, horizontal staff 2, standpipe 3 and vertical scale 4; Described bottom transverse tube 1 is that a length is greater than the square tube that gauge is less than span length, and on bottom transverse tube 1, plane is provided with base register pin 5, and a gauge locating piece 6 is respectively welded at transverse tube 1 lower plane two ends in bottom; Described horizontal staff 2 is to insert the square tube with scale of bottom in transverse tube 1, and horizontal staff 2 inserts rear one end of transverse tube 2, bottom and exposes, and exposes and on head, has plug 7 upward; Described standpipe 3 is the square tubes that can insert on plug 7, and standpipe 3 is provided with standpipe register pin 8; Described vertical scale 4 is the square tubes with scale that can insert in standpipe 3.
Above-mentioned transverse tube 1, horizontal staff 2, standpipe 3 and vertical scale 4 also can be pipe.
During use, first by each assembling parts together, horizontal staff 2 is inserted to bottom transverse tube 1, fixing with base register pin 5, standpipe 3 is inserted on plug 7, vertical scale 4 is inserted in standpipe 3, fixing with standpipe register pin 8; During measurement, utilize gauge locating piece 6 that bottom transverse tube 1 is snapped on track, unclamp base register pin 5, extract horizontal staff 2 out, measure the breadth extreme that track needs to lane side, track behind location in extraction vertical scale 4 measurement permission width ranges, to back gap, verifies according to main equipment entrucking full-size whether lifting vehicle can safe operation in tunnel.
