Abstract
Measure the depth of storehouse by a weight hammer block and a scaled string. It is characterized in that the top of gravity hammer block connects with the scaled string and the other end of the scaled string passes the fast pulley which is on the spring balance at the same time the spring balance fixes on the pulley yoke. When the gravity hammer block and the scaled string suspend in the air of the colliery storehouse the value of the spring balance is the total of the weight of the gravity hammer block and the scaled string; when the gravity hammer block descends at the place of material in the colliery storehouse the gravity hammer block is bared by the material in the colliery storehouse so it cannot descend continually and the number of the spring balance displays declining greatly while the graduation value of the string balance at the moment is the depth of the storehouse.
Description
Technical field: heavy-hammer coal-mine cabin-thickness measuring method belongs to the coal-mine cabin field, particularly measures coal storage coal position.
Background technology: by retrieval both at home and abroad comprehensively, heavy-hammer coal-mine cabin-thickness measuring method belongs to initiative both at home and abroad, coal-mine cabin coal storage position, and normally the workman observes with head lamp, does not usually see greatly because of coal dust or causes visual error, causes the accident.
Main contents: the objective of the invention is problem at above-mentioned existence, according to the different location, the coal-mine cabin of different depth, utilize the weight body and have the scale cord and measure the coal-mine cabin degree of depth, it is characterized in that weight body top and have the scale cord linking, the band scale cord other end passes through fixed pulley, fixed pulley is on spring balance, spring balance is fixed on the pulley yoke, when the weight body and the band scale cord together when coal-mine cabin is aerial, numeral on its spring balance is weight body weight and band scale cord weight sum, when the weight body drops to when the material place is arranged in the coal-mine cabin, the weight body is subjected to stopping of the interior material of coal-mine cabin, can not continue to descend, the spring balance reading descends greatly, and be exactly warehouse depth value with the scale value on the scale cord this moment.Another kind method is manually to catch band scale cord with hand, reads numeral on the band scale cord according to weight change, determines the coal-mine cabin degree of depth.
Heavy-hammer coal-mine cabin-thickness measuring method compared with prior art has the following advantages:
1, method is simple, and practical reliable, cost is low.
2,, only can realize measuring the coal-mine cabin coal position and the coal-mine cabin degree of depth with weight change without the light photograph.
3, easily be automated, and can expand to the various material bins of coal-mine water-house and ground, as silo etc.
Description of drawings:
Accompanying drawing is the heavy-hammer coal-mine cabin-thickness measuring method synoptic diagram.
1, weight body; 2, band scale cord; 3, fixed pulley;
4, spring balance; 5, pulley yoke; 6, coal-mine cabin.
Specific embodiments: existing is the example explanation with the accompanying drawing: weight body (1) is hung on the band scale cord (2), band scale cord (2) other end is by fixed pulley (3), fixed pulley (3) is fixed on the spring balance (4), spring balance (4) is fixed on the pulley yoke (5), when weight body (1) and band scale cord (2) together coal-mine cabin (6) in the air the time, numeral on the spring balance (4) is the weight and band scale cord (2) weight sum of weight body (1), when weight body (1) drops to when in the coal-mine cabin (6) the material place being arranged, weight body (1) is subjected to stopping of coal-mine cabin (6) interior material, can not continue to descend, spring balance (4) is gone up reading and is descended greatly, and be exactly coal-mine cabin (6) depth value and coal-mine cabin (6) interior coal position position with the scale value on the scale cord (2) this moment.Thereby realized heavy-hammer coal-mine cabin-thickness measuring method.
Claims (2)
1, heavy-hammer coal-mine cabin-thickness measuring method, it is characterized in that: weight body top with have the scale cord and link, the band scale cord other end passes through fixed pulley, fixed pulley is on spring balance, spring balance is fixed on the pulley yoke, when weight body and band scale cord together when coal-mine cabin is aerial, numeral on its spring balance is weight body weight and band scale cord weight sum, when the weight body drops to when the material place is arranged in the coal-mine cabin, the weight body is subjected to stopping of the interior material of coal-mine cabin, can not continue to descend, the spring balance reading descends greatly, is exactly the warehouse depth value and be with scale cord high scale value this moment.
2, heavy-hammer coal-mine cabin-thickness measuring method is characterized in that: manually catch band scale cord with hand, according to weight change, read the numeral on the band scale cord, determine the coal-mine cabin degree of depth.
