Abstract
The present invention relates to a technical method of hydraulic support and prop stanchion load-carrying pressure-bearing safety monitoring system equipment. It is characterized by that said safety monitoring system equipment includes program digital computer, display screen, digital exchange and inductor. The digital exchange can be used for transferring the hydraulic support load-carrying condition fed back by inductor to digital computer, in said program digital computer the safety pressure limit, pressure reduction warning limit and pressure increment warning limit are set. When the hydraulis support load and pressure are reduced or increased, the program digital computer can give out warning signal so as to implement safety protection of operation machine and person.
Description
Background technology
At present, known hydraulic support by back timber, base, column, push unit, etc. form.Open operation valve feed liquor handle, liquid enters the column cavity of resorption by operation valve, hydralic hose, individual event valve, hydraulic support is risen, play the load effect, can the pressure system device be set owing to existing hydraulic support, still unaware for the pressure-bearing situation of hydraulic support, though relief valve device is arranged, the load size that cannot show its hydraulic support, sometimes because of pressure is too big, the dress safety valve backs down, hydraulic support falls after rise, causes the accident.
Summary of the invention:
Deficiency in the time of can not monitoring pressure-bearing amount and prevention landslide in order to overcome existing hydraulic support, the invention provides hydraulic support payload security monitoring system device, the pressure-bearing situation that this setting not only can be monitored hydraulic support plays and gives warning in advance, and after can also handling by data analysis, but the great landslide accident of early warning.
The technical solution adopted for the present invention to solve the technical problems is: hydraulic support by back timber, base, column, push unit, etc. form.Setting program digital computer, digital switch, pressure inductor are connected by signal transmssion line; In one way valve and safety valve junction, set up a threeway, by threeway one way valve, safety valve, pressure inductor are connected.Digital switch transfers to pressure inductor by signal transmssion line with signal, and with the detection simulation signal that pressure inductor feeds back to, converts data signal to, by signal transmssion line, transfers to program digital computer; Be provided with in process computer that hydraulic support safe pressure limit, pressure reduce the early warning limit, pressure increases to the danger early warning limit.Program digital computer is monitored hydraulic support load-bearing state automatically, and by signal transmssion line, signal is transferred to display screen it is shown.In the production operation, suppose one or youngster's frame hydraulic support, load-bearing is reduced to early warning in limited time, the program digital computer early warning, and demonstrate operation area, how many supports by the buzzing of signal transmssion line instruction buzzer, display screen, the monitor staff in time notifies operating worker, and its pressure is recovered.Otherwise, if top board landslide, the support pressure-bearing increases, when pressure is increased to early warning in limited time, the program digital computer early warning, and demonstrate the workspace by the buzzing of signal transmssion line instruction buzzer, display screen, how many supports, both will cave in area and situation, the monitor staff in time notifies the workman to withdraw the operation area in order, or gets corresponding technical safety measures.
The invention has the beneficial effects as follows:
The load-bearing situation of the not only round-the-clock monitoring hydraulic support of the present invention, bigger effect is, by monitored data to every hydraulic support, can play giving warning in advance of counterweight large tracts of land landslide accident, make the operating personnel in time withdraw operation field, or take corresponding technical measures, accident is dropped to minimum.If landslide also can pass through monitored data, know cave in area and scope, can organize related measure such as speedily carry out rescue work apace.
The present invention is further described below in conjunction with accompanying drawing:
Fig. 1 is the system construction drawing of the technical method of hydraulic support of the present invention, pillar system unit of monitoring load-bearing safety.
Fig. 2 is the enlarged detail of Fig. 1.
1 hydraulic support among the figure, 2 program digital computers, 3 digital switch, 4 pressure inductors, 5 display screens, 6 buzzers, 7 signal transmssion lines, 8 columns, 9 main feed tubes, 10 main liquid back pipes, 11 operation valves, 12 feed tubes, 13 liquid back pipes, 14 one way valves, 15 cavity of resorptions, 16 threeways, 17 safety valves, 18 power lines, 19 other operation area signal transmssion lines, 20 back timbers, 21 bases, 22 push units, 23 safe pressures limit, 24 pressure reduce the early warning limit, and 25 pressure increase the early warning limit.
At Fig. 1, hydraulic support among Fig. 2 (1) by back timber (20), base (21), column (8), push unit (22), etc. form.Setting program digital computer (2), buzzer (6), display screen (5), digital switch (3), pressure inductor (4) are connected by signal transmssion line (7); In one way valve (14) and safety valve (17) junction, set up a threeway (16), by threeway (16) one way valve (14), safety valve (17), pressure inductor (4) are connected; Digital switch (3) transfers to pressure inductor (4) with signal, and with the analog signal that pressure inductor (4) detects, converts data signal to by signal transmssion line (7), by signal transmssion line (7), transfers to program digital computer (2); (2) are provided with hydraulic support safe pressure limit (23) in process computer, pressure reduces early warning and limits (24), pressure to increase to danger early warning limit (25).Program digital computer (2) is monitored hydraulic support load-bearing state automatically, and by signal transmssion line (7), signal is transferred to display screen (5), with its demonstration.To operate valve (11) handle and be opened into raised position, liquid enters column (8) cavity of resorption (15) by operation valve (11), feed tube (12), one way valve (14), and hydraulic support (1) is risen.After hydraulic support (1) props up top board, shutoff operation valve (11), one way valve (14) is closed automatically, with liquid barrier in the cavity of resorption (15) of column (8); At this moment, hydraulic support (1) can produce certain pressure, this pressure signal is set at 0 in process computer (2), be safe pressure limit (23), hydraulic support (1) pressure reduces signal and is set to-1 ,-2,-3 ... until being reduced to early warning limit (24), hydraulic support (1) pressure signal increase be set to+1 ,+2 ,+3 ... until increasing to early warning limit (25).In the production operation, suppose one or several hydraulic supports (1) load decompression, when pressure signal is reduced to early warning limit (24), program digital computer (2) early warning, and demonstrate the operation area by the buzzing of signal transmssion line (7) instruction buzzer (6), display screen (5), several hydraulic supports (1) decompression, the monitor staff in time notifies the operating personnel, and its pressure is recovered.Otherwise, if top board landslide, hydraulic support (1) pressure-bearing increases, when pressure signal increases to early warning limit (25), program digital computer (2) early warning, and instruct buzzer (6) buzzing, display screen (5) to demonstrate the operation area by signal transmssion line (7), several hydraulic supports (1), both will cave in area and situation, the monitor staff in time notifies the operating personnel to withdraw the operation area in order, or gets corresponding technical safety measures.
