Abstract
A leakage alarm of single-body hydraulic support-column is suitable for the single-body hydraulic support-column of the supporting top plat of the coal mine well; the utility model comprises two cylinders which are sleeved and jointed with each other; the baffles are respectively arranged in two cylinders; a spring and a spacing fixing part are arranged between the baffles; a circuit switch controlled by the variation of the relative position of two cylinders is connected on an alarm device. The utility model has simple structure, is made easily and used conveniently, induces sensitively, delivers obvious warning and has good using effect; the alarm is used, thus finding the problem of the liquid leakage in time, being convenient for taking measures as soon as possible, controlling the danger and hidden trouble in the blade, avoiding the accident from happening and enhancing the safety of the production.
Description
The utility model relates to a kind of hydraulic prop leakage alarm, is applicable to the hydraulic prop of coal mine roof supporting.
Coal mining is underground activities, and dangerous big, safety problem is matter of utmost importance especially.The support column that roof supporting uses in the mine is hydraulic prop, and the liquid bigger by pressure forms shore supports, therefore, occurs the leakage problem easily.In a single day leakage appears in pillar, just loses support force, causes the top board slump, very easily causes personal injury and property loss.How in time to discover problems and solve them, how dangerous hidden danger is controlled at bud, what avoid accident is vital.Also there is not good solution on the one hand at this at present.
The purpose of this utility model is to provide a kind of structure tube list reasonable, makes easily, and easy to use, the hydraulic prop leakage alarm that result of use is good uses this alarm, can in time find the leakage problem, is convenient to take measures early, avoids the generation of accident.
Hydraulic prop leakage alarm described in the utility model, the cylindrical shell that comprises two mutual sheathing butt joints, be respectively equipped with baffle plate in two cylindrical shells, establish spring and positioning limiting fixator between baffle plate, the contactor that is changed control by two cylindrical shell relative positions is connected on the warning device.
Two barrel jackets are connected together, place hydraulic prop above.When the hydraulic pressure in the pillar was in normal condition, the spring in the sleeve was compressed, and the circuit of warning device is in off-state, and the expression situation is stable.When the phenomenon of leakage occurring, the hydraulic pressure in the pillar reduces, and then compressed spring will open, and promotes two cylindrical shells and throws off a segment distance mutually.The variation of two cylindrical shell relative positions touches the contactor of warning device, is communicated with warning circuit, realizes in time reporting to the police, thereby can in time discover problems and solve them, and dangerous hidden danger is controlled at bud, avoids the generation of accident, has strengthened the safety of producing.
In the utility model:
Positioning limiting fixator is screw rod, and is simple in structure, is convenient to make and use operation, limits the relative position relation of two sleeves.
External surface at the socket place inner sleeve of two sleeves is set up reflective material layer, can further strengthen the caution effect.Under the normal condition, two sleeve sockets, reflective material layer is covered; When leakage occurring, two cylindrical shells are thrown off a segment distance, and reflective material layer is come out, and under the irradiation of mine lamp etc., send light, strengthen the caution performance.
Warning device of the present utility model adopts existing alarm technique to get final product, and can be audible alarm, can be that light is reported to the police, can be acousto-optic in conjunction with warning, also can be warning of other form or the like, concrete condition is tired no longer in detail to be stated.
Be described further below in conjunction with the embodiment accompanying drawing.
Fig. 1, the utility model example structure schematic diagram.
Among the figure: 1 upper shell, 2,6 baffle plates, 3 springs, 4 screw rods, 5 reflector layers, 7 lower shells, 8,11 terminals, 9 back-moving springs, 10,12 fixtures, 13 copper coin sheets, 14 leads, 15 warning devices.
As shown in the figure, hydraulic prop leakage alarm described in the utility model, comprise the cylindrical shell 1,7 of two mutual sheathing butt joints up and down, be respectively equipped with baffle plate 2,6 in two cylindrical shells 1,7,2,6 on baffle plate is established spring 3 and spacing screw rod 4, the contactor that is changed control by two cylindrical shell relative positions is connected on the warning device 15, and the external surface of the socket place inner sleeve of two sleeves 1,7 is coated with reflective material layer 5.Warning device wherein is that loudspeaker sound is reported to the police, use battery to be the dry cell under the safe voltage, two terminals of contactor are located at the lower end of baffle plate 6 and screw rod 4 respectively, specifically constitute: terminals 11 of contactor are fixedly connected on the conduction good conductor copper coin sheet 13 that is attached on baffle plate 6 external surfaces by fixture 12, another terminals 8 of contactor are free end, be fixed on the lower end of screw rod 4 by fixture 10, add back-moving spring 9 and can improve functional performance, guarantee nonexpondable good result, increase access times, increase the service life.
During use, two cylindrical shells 1,7 connect together, place hydraulic prop above.When the hydraulic pressure in the pillar was in normal condition, the spring 3 in the sleeve was compressed, and the free terminals 8 of the lower end of screw rod 4 and the circuit that is fixed thereon are separated from baffle plate 6, and warning circuit is in off-state, and the expression situation is stable.When the phenomenon of leakage occurring, the hydraulic pressure in the pillar reduces, and then compressed spring 3 will open, and promotes two cylindrical shells 1,7 and throws off mutually, makes baffle plate 6 touch the free terminals 8 of warning circuit, is communicated with entire circuit by copper coin sheet 13, realizes in time reporting to the police.Simultaneously, two cylindrical shells are thrown off a segment distance, and reflective material layer 5 is come out, and under the irradiation of mine lamp etc., send light, strengthen the caution performance.
The utility model is simple and reasonable, makes easily, and easy to use, induction is sensitive, warns obviously, and result of use is good.Use this alarm, can in time find the leakage problem, be convenient to take measures early, in time change qualified hydraulic prop, dangerous hidden danger is controlled at bud, avoid the generation of accident, strengthen the safety of producing.
