Abstract
The problem that the timely alarming of a single hydraulic prop cannot be implemented due to the overloading is resolved through an alarming pillar of coal mines which is characterized in that a cylindrical fuel tank (2) is provided and a base is arranged below the fuel tank (2) on which a piston (3) is provided. The inside of the piston (3) is provided with a piston body (4) in which the top is provided with a tectum (5). Between the piston (4) and the fuel tank (2), a pressure sensor box (6) is provided, in which the inside is provided with an alarm (7) linked with a pressure sensor (8). The pressure sensor (8) is connected to a tectum (5), and a power (9) is in series connection between the alarm (7) and the pressure sensor (8). The utility model has the advantages of simple structure and easy operation, in which the problem occurs in the single hydraulic prop can be directed found and alarmed. Therefore, the utility model is particularly applicable for the support in coal mines.
Description
Technical field
The utility model belongs to monomer support apparatus manufacturing technology field, colliery, is specifically related to a kind of colliery warning pillar.
Background technology
At present, the monomer supporting product that uses on the home and abroad colliery mostly is hydraulic prop, and this hydraulic prop all uses the piston type know-why, and the inner surface of its piston and oil cylinder is a high pressure sealing face, therefore when pillar ran into working resistance, oil cylinder will produce elastic expansion.So the pressure that bears when hydraulic prop has reached the pressure limit that it bears, and this moment, operating personnel can't find, so just were easy to take place a series of personnel casualty accidentses such as colliery roof fall, thereby brings threat for underground labour's personal safety.Outer existing hydraulic prop mostly is outside injection type hydraulic pillar, this pillar relies on the pressure liquid of emulsion pump output to support, because support force is to provide by the fluid pressure of importing, so when the pressure of liquid pump input is excessive, will surpass the pressure that the pillar high pressure sealing face can bear, thereby having weakened the support capacity of pillar, is that pressure is excessive or the hydraulic prop that other problems is present all is that operating personnel can't find again.
Summary of the invention
The purpose of this utility model is exactly for overcoming above deficiency, and the excessive or other problems of pressure appears in a kind of direct discovery hydraulic prop that provides, and the colliery warning pillar of energy alarm.
The purpose of this utility model technical scheme is to realize like this, described colliery is that a cylinder oil cylinder (2) is set with its structure of warning pillar, oil cylinder (2) is divided into bottom set seat (1), on piston (3) is set, piston body (4) is set in the piston (3), piston body (4) is gone up the top top cover (5) is set, it is characterized in that at piston body (4) and oil cylinder (2), between a pressure sensing box (6) is set, one alarm (7) is set in pressure sensing box (6), alarm (7) connects a pressure sensor (8), and pressure sensor (8) is connected with top cover (5), is connected in series a power supply (9) between alarm (7) and the pressure sensor (8).The utility model is on the basis of advantages such as the ability to bear that has at traditional hydraulic prop is big, the anti-bias load ability is strong, has increased roof pressure is passed to above the warning circuit.The pressure that is subjected to when it will sound the alarm when reaching the maximum pressure value that it can bear automatically, and the prompting personnel in the pit is dangerous now, thereby reduces the personnel casualty accidents that causes because of the colliery roof fall, ensures coal mine production safety and staff's life security.
Colliery of the present utility model warning pillar, have that direct discovery hydraulic prop goes wrong and can alarm function, and simple in structure, easy to operate, safe and reliable, avoid taking place the advantage of colliery roof fall accident.
Description of drawings:
Accompanying drawing is a colliery warning pier construction schematic diagram
1. base, 2. oil cylinder, 3. piston, the cylinder of 4. living, 5. top cover, 6. sensing box, 7. alarm, 8. pressure sensor, 9. power supply
The specific embodiment:
Provide most preferred embodiment below in conjunction with accompanying drawing the utility model is done further detailed explanation, the colliery is that a cylinder oil cylinder (2) is set with the warning pillar as shown in drawings, oil cylinder (2) is divided into bottom set seat (1), on piston (3) is set, piston body (4) is set in the piston (3), piston body (4) is gone up the top top cover (5) is set, at piston body (4) and oil cylinder (2), between a pressure sensing box (6) is set, one alarm (7) alarm (7) is set in pressure sensing box (6) connects a pressure sensor (8), pressure sensor (8) is connected with top cover (5), is connected in series a power supply (9) between alarm (7) and the pressure sensor (8).The utility model is adapted to general enterprise and produces.
Claims (1)
1. the colliery is that a cylinder oil cylinder (2) is set with its structure of warning pillar, oil cylinder (2) is divided into bottom set seat (1), on piston (3) is set, piston body (4) is set in the piston (3), piston body (4) is gone up the top top cover (5) is set, it is characterized in that at piston body (4) and oil cylinder (2), between a pressure sensing box (6) is set, one alarm (7) is set in pressure sensing box (6), alarm (7) connects a pressure sensor (8), pressure sensor (8) is connected with top cover (5), is connected in series a power supply (9) between alarm (7) and the pressure sensor (8).
