Description
Technical field
The invention belongs to down-hole coal excavation apparatus, particularly a kind of intelligent protecting against shock holder device.
Background technology
Degree of depth exploitation is the inexorable trend of coal industry development; It is all obviously different with superficial part with the engineering response characteristic that the deep coal and rock is formed architectural feature, deformation failure characteristic, energy release characteristic; More be prone to bring out the bump disaster; Cause down-hole heavy damage and personnel casualty accidents, this has become the colliery major accident that takes place in recent years and has confirmed.Therefore, bump mine laneway country rock safety support becomes the exploitation of China deep resource and demands urgently studying a question.Hydraulic support has been obtained good result as coal mine roadway passive protecting mode, but a large amount of supports are destroyed statistical analysis, and mainly there is following problem in existing support: opposing shock loading ability when impacting, is prone to cause support, roadway destruction; Opposing two helps load-carrying ability poor, and two when helping to press, and support is toppled over easily, destroyed; Do not resist the pucking ability, during pucking, support can not carry bottom load.
Summary of the invention
The objective of the invention is to overcome above-mentioned technical deficiency, provide a kind of supporting capacity strong, intelligent protecting against shock holder device esy to use, safe and reliable.
The technical scheme that technical solution problem of the present invention adopts is: intelligent protecting against shock holder device comprises: back timber, bottom girder, pin, hydraulic support, baffle plate, strain gauge, displacement transducer; Be characterized in being divided into two halves from the centre at back timber, bottom girder; With pinning two halves back timber, two halves bottom girder pin are linked together cutting apart the place; The upper end of hydraulic support is connected with back timber; The lower end of hydraulic support is connected with bottom girder, between back timber and bottom girder, is provided with baffle plate, baffle plate middle part Installation Stress sensor; At hydraulic support lower side installation position displacement sensor and erosion control assembly, the erosion control assembly comprises hydraulic pump, one way valve, overflow valve, hydraulic energy storage device one, two, reversal valve, hydraulic cylinder; The annexation of erosion control assembly is: hydraulic pump connects one way valve, and one way valve connects overflow valve and hydraulic accumulator, and hydraulic accumulator connects reversal valve, and reversal valve connects hydraulic accumulator, and hydraulic accumulator connects hydraulic cylinder.
The invention has the beneficial effects as follows: intelligent protecting against shock holder device is in shock loading; When the hydraulic support safety valve comes not anxious the unlatching; Hydraulic energy storage device absorbs impact energy, effectively protects the cylinder body spalling, after the impact; Accumulator is given support energy supplement again, has increased elasticity, the impact resistance of hydraulic support.Baffled playing born tunnel coal petrography horizontal force between top, bottom girder two ends; Strengthen support opposing load-carrying ability; Play protection hydraulic support effect, the strain gauge that install at the baffle plate middle part can reflect that tunnel two helps pressure condition, can according to circumstances add strong supporting.Installation position, hydraulic support bottom displacement sensor can reflect support compression situation, can better reflect the roof pressure condition, can add strong supporting according to the displacement situation; Bottom girder plays opposing pucking ability; This device overall structure stability is stronger, collapsible, makes things convenient for carrying and installation.
Description of drawings
Specify with embodiment below in conjunction with accompanying drawing.
Fig. 1 is intelligent protecting against shock holder device structure chart.
Fig. 2 is an erosion control assembly assumption diagram among Fig. 1.
Among the figure, the 1-pin; The 2-back timber; The 3-bottom girder; The 4-hydraulic support; The 5-baffle plate; The 6-strain gauge; 7-erosion control assembly; The 7-1-hydraulic pump; The 7-2-one way valve; The 7-3-overflow valve; 7-4-hydraulic accumulator one; The 7-5-reversal valve; The 7-6-hydraulic cylinder; 7-7-hydraulic accumulator two; The 8-displacement transducer.
The specific embodiment
Embodiment, with reference to accompanying drawing 1,2, the back timber 2 of intelligent protecting against shock holder device and the intermediate section of bottom girder 3 are slit into two halves, are hinged and connected to together with the two halves of pin 1 with back timber 2 and bottom girder 3 at the place of cutting apart, centre of back timber 2 and bottom girder 3.The top of hydraulic support 4 and low side are hinged the two ends of back timber 2 and bottom girder 3 respectively.Between back timber 2, bottom girder 3 two ends and baffle plate 5 be hinged.Installation Stress sensor 6 in the middle of the baffle plate 5.The bottom side installation position displacement sensor 8 and the erosion control assembly 7 of hydraulic support 4.Erosion control assembly 7 is that hydraulic pump 7-1 connects one way valve 7-2, and one way valve 7-2 connects overflow valve 7-3 and hydraulic accumulator 7-4, and hydraulic accumulator 7-4 connects reversal valve 7-5, and reversal valve 7-5 connects hydraulic accumulator 7-7, and hydraulic accumulator 7-7 connects hydraulic cylinder 7-6.
When intelligence protecting against shock holder device back timber 2 was hit pressure with bottom girder 3, safety valve came not anxious the unlatching, and liquid is squeezed into hydraulic energy storage device 7-7 among the hydraulic cylinder 7-6, and hydraulic energy storage device 7-7 can absorb the impact energy effect, effectively protects the cylinder body spalling; After the impact, accumulator 7-7 can give hydraulic cylinder 7-6 energy supplement again, and in the time of realizing impact, support lets bit function fast.When tunnel two is helped to press; Tea is helped to carry in baffle plate 5 opposing tunnels two; Effectively protect hydraulic support, the strain gauge 6 that install at baffle plate 5 middle parts can reflect in real time when pressure condition is helped in tunnel two that installation position, hydraulic support 4 bottom displacement sensor 8 can reflect hydraulic support 4 compression situation.3 anti-pucking abilities of bottom girder prevent that effectively tunnel pucking accident from taking place.
