Description
Technical field:
The utility model relates to a kind of mine production individual prop, particularly a kind of wind pressure type glass fiber reinforced plastic individual prop.
Background technology:
At present, in mine is produced, the support form that is used for driving faces such as rock gangway, coal road from before shed shoring progressively be improved to bolt support, this temporary lining to the driving face empty top zone has produced a series of problems, and the temporary lining mode that is adopted during shed shoring is inapplicable in bolt support.Existing most units adopt round log to carry out temporary lining, but because round log length is certain, and the height of driving face is difficult to be consistent in the real work, not only is difficult to operation, and supporting effect is very undesirable, so security incident happens occasionally.Other has some units to carry out temporary lining with hydraulic prop, several shortcomings below hydraulic pressure steel individual prop exists in actual production: 1 hydraulic pressure steel individual prop has only by reaching job requirement to the water filling of pillar inner high voltage, realize that water filling must have water source and hydraulic pump, because the driving face environment is abominable, the region is narrow and small, hydraulic system and pipeline are placed difficulty, and very inconvenience operates; And part is too slow with hand-hydraulic pillar landing speed, has a strong impact on job schedule; Must discharge water behind the temporary lining end-of-job in addition and rush down pressure, the water of emitting is to producing and causing a hidden trouble safely.2 hydraulic pressure steel individual prop weight are relatively large, and it is quite heavy to operate, and labour intensity is big, inefficiency.
Summary of the invention:
The purpose of this utility model is the described defective that exists in existing the production, and a kind of production security that can improve is provided, and reduces labor intensity the blast glass fiber reinforced plastic pillar of increasing work efficiency.
The purpose of this utility model is achieved through the following technical solutions.
A kind of glass fiber reinforced plastic pillar comprises that top cover, cylinder body, carriage, valve body and high-pressure rubber pipe etc. partly form, and the top of cylinder body is provided with top cover, is connected by flange between top cover and the cylinder body, is provided with sealing mat between the flange, and affixed by bolt.The both sides, bottom of cylinder body are respectively equipped with holder handle and valve body, are provided with high-pressure rubber pipe and lead to top cover and valve body, and the coupling part of high-pressure rubber pipe and top cover is provided with suction nozzle.
Valve body is provided with handle, handgrip and valve, and the next door of valve is provided with safety valve, and the lower end of valve body is provided with air inlet port.
Cylinder body comprises interface block, and is connect and formed by urceolus, one-level cylinder barrel, secondary cylinder jacket casing.
Glass fiber reinforced plastic pillar of the present utility model, be mainly used in driving faces such as rock gangway, coal road, can guarantee under identical working strength situation, to solve the existing defective of hydraulic pressure steel individual prop in the conventional art, thereby improve production security, reduce labor intensity, increase work efficiency.

Among the figure: 1, top cover, 2, U type pin, 3, asbestos pad, 4, flange, 5, bolt, 6, pad, 7, nut, 8, high-pressure rubber pipe, 9, urceolus, 10, one-level cylinder barrel, 11, the secondary cylinder barrel, 12, hand-control device, 13, the tapering nut, 14,15 dust rings, 16, the holder handle, 17,18 sealing rings, 19, base plate, 20, safety valve, 21, handle, 22, handgrip, 23, air inlet port, 24, valve, 25, suction nozzle, 26, sealing mat, 27, interface block.
The specific embodiment:
As shown in Figure 1, top cover 1 is provided with U type pin 2 with the coupling part of high-pressure rubber pipe 8, is connected by flange 4 between top cover 1 and the steel cylinder, and flange 4 centres are lined with asbestos pads 3, flange is affixed by bolt 5, nut 7 and pad 6 about in the of 4, and the opposite side of top cover 1 is added with sealing ring 17,18.Steel cylinder comprises urceolus 9, one-level cylinder barrel 10, secondary cylinder barrel 11, from socket outside to inside.High-pressure rubber pipe 8 is positioned at place, cylindrical shell bottom and is provided with hand-control device 12, and cylindrical shell bottom opposite side is provided with holder handle 16 outward, and cylindrical shell bottom one-level cylinder barrel and secondary cylinder tube socket place are provided with dust ring 15, and the barrel bottom is provided with dust ring 14.With compressed air is medium, and compressed air is in valve body enters cylinder body during work.
Shown in Fig. 2,3, valve body comprises valve 24, base plate 19, and safety valve 20, handle 21 and handgrip 22, the valve body end is provided with air inlet port 23.
As shown in Figure 4, the top of glass fiber reinforced plastic pillar comprises between top cover 1, top cover 1 and the cylinder body and being connected by flange 4, is provided with sealing mat 26 between the flange, and by bolt 5 is affixed up and down.The coupling part of sebific duct and top cover is provided with suction nozzle 25.
As shown in Figure 5, be equipped with sealing ring 18 between one-level cylinder barrel 10 and the secondary cylinder barrel 11, top cover 1 is provided with interface block 27 with urceolus 9 junctions.When the compressed air that enters reaches certain pressure, secondary cylinder barrel 11 pressurizeds begin outside stretching, extension, along with compressed-air actuated continuous injection, one-level cylinder barrel 10 pressurizeds began outside stretching, extension when stretching, extension reached the limitation of length, valve-off when elongation and pressure reach job requirement.When if roof pressure oversteps the extreme limit load; the safety valve automatically unloading; safety valve cuts out when pressure is returned to rated operating pressure; the glass fiber reinforced plastic individual prop enters duty; the so effectively safety of cover glass steel individual prop; and roof weighting is in time unloaded, also can play forewarning function.After work is finished, open control valve, the pillar compressed air is discharged, and pillar descends, and finishes a working cycles.
