Abstract
The utility model relates to a special ruler for measuring narrow rail gauges in underground mines. The front surfaces, the reverse surfaces and the tops of double shoulders on the two sides of a T-shaped flat plate are provided with millimeter-level scales. The width of the lower section of the T-shaped flat plate is equal to the rated rail gauge of narrow rails of underground mines. The T-shaped flat plate is a stainless steel flat plate, an aluminum alloy flat plate or a nylon plastic flat plate. During measurement, the measured values of the gaps between the T-shaped flat plate and the side surfaces of the upper head parts of the steel rails, namely the out of tolerance L of rail gauge, are checked, and the L should be less than 2% of the rated rail gauge. The special ruler is simple in structure, practical, convenient, and durable and is convenient for reading and accurate in measurement. The T-shaped flat plate is a stainless steel flat plate, an aluminum alloy flat plate or a nylon plastic flat plate and thus cannot be rusted or broken easily.
Description
Technical field
The utility model relates to a kind of instrument of measuring gauge, particularly a kind of special ruler of measuring underground mine narrow gauge gauge.
Background technology
Underground mine is widely used in the dinkey and the mine car that on narrow gauge, move and carries out ore, material, equipment or personnel's transportation, and travelling speed is slower, is generally 2-3 meter per second.When operation, not very high to the accuracy requirement of gauge, be generally no more than 2% of specified gauge and can guarantee safe operation.
Traditional method is to adopt steel tape or straight steel ruler to measure gauge, and two ends are difficult for aiming at, and measuring accuracy is low; Steel rail laying, at the roadway floor of underground mine, has water and silt, and working condition is poor, and steel tape or straight steel ruler damage in the easy corrosion of use procedure, causes that scale is unclear, corrosion fracture, serviceable life be short.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of simple and convenient, measure and measure more accurately the special ruler of underground mine narrow gauge gauge.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of special ruler of measuring underground mine narrow gauge gauge, front, the reverse side of the dull and stereotyped both sides of T shape both shoulders and be provided with grade scale above, the width of the dull and stereotyped hypomere of T shape equals the specified gauge of underground mine narrow gauge.Specified gauge G=600mm or the G=900mm of described underground mine narrow gauge.Described T shape flat board is stainless steel flat plate, flat aluminium alloy plate or nylon plastic(s) flat board.
The beneficial effects of the utility model are:
1, simple in structure, practical and convenient, durable in use.
2,, while measurement, push up to a side rail dull and stereotyped T shape, convenient reading, it is more accurate to measure.
3, dull and stereotyped stainless steel flat plate, flat aluminium alloy plate or the nylon plastic(s) flat board of adopting of T shape, is difficult for corrosion or fractures.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
embodiment 1as shown in Figure 1, 2: a kind of special ruler of measuring underground mine narrow gauge gauge, front, the reverse side of the dull and stereotyped 1 both sides both shoulders 2 of T shape and be provided with grade scale 3 above, the width of dull and stereotyped 1 hypomere of T shape equals the specified gauge of underground mine narrow gauge.
The specified gauge G=600mm of described underground mine narrow gauge.
T shape dull and stereotyped 1 is stainless steel flat plate, setting height H=40--50 mm of T shape flat board 1, thickness B=3--5mm.
embodiment 2as shown in Figure 1, 2; The specified gauge G=900mm of the second of underground mine narrow gauge described in embodiment 1.Described T shape dull and stereotyped 1 is flat aluminium alloy plate or nylon plastic(s) flat board.
embodiment 3as shown in Figure 1, 2; Described in employing embodiment 1, the method for special ruler measurement underground mine narrow gauge gauge is:
[1] T shape dull and stereotyped 1 is inserted between two parallel steel rails of underground mine, the both sides both shoulders 2 of T shape flat board 1 are placed on the rail level of rail head portion 4, and T shape flat board 1 should be perpendicular to two parallel steel rails; If T shape flat board 1 can not insert between two parallel steel rails, or can not be perpendicular to two parallel steel rails, illustrate that actual gauge is less than specified gauge, be defective, should adjust to specified gauge;
[2] after T shape dull and stereotyped 1 is inserted between two parallel steel rails, T shape dull and stereotyped 1 is pushed up to a side rail;
[3] check the side clearance measured value of T shape dull and stereotyped 1 and rail head portion 4, i.e. the overproof L of gauge;
[4] underground mine safety regulations regulation, the overproof L of gauge should be less than 2% of specified gauge; If the overproof L of gauge is greater than 2% of specified gauge, be defective, should adjust to specified gauge.Specified gauge G=600mm, the overproof L of gauge should be less than 12mm; Specified gauge G=900mm, the overproof L of gauge should be less than 18mm.
Claims (3)
1. measure the special ruler of underground mine narrow gauge gauge for one kind, it is characterized in that: front, the reverse side of a T shape flat board (1) both sides both shoulders (2) and be provided with grade scale (3) above, the width of T shape flat board (1) hypomere equals the specified gauge of underground mine narrow gauge.
