Abstract
The utility model provides a late-model automatic spraying dust eliminating device on the hydraulic bracket system of a working surface in a coal mine. The late-model automatic spraying dust eliminating device improves a hydraulic control water valve in the existing spraying device to cause the hydraulic control water valve to be provided with two valve holes and two valve cores, and water inlet holes are connected with two valve holes. Both sides of a valve body are provided with two water outlet pipes and hydraulic control pipelines. The improved automatic spraying dust eliminating device uses one hydraulic control water valve and one water inlet pipe, and the improved automatic spraying dust eliminating device can simultaneously accomplish spraying and eliminating dust for the opening windows of the back hiding beams or the hydraulic brackets of the opening tail beams of double transporters backwards and forwards. The production cost is reduced, and the fund is saved.
Description
The utility model relates to the coal mine work area supporting, especially is loaded on the dust guard in the hydraulic bracket system.
In colliery system is dustproof, advanced spray dust prevention technology have that Shanxi service company of Wangzhuang Coal Mine, Lu'an Mineral Bureau produces " hydraulic pressure automation spray device for reducing dust, the patent No. are 91206439.This device is by the hydraulic control water valve with a through hole and a spool, the water inlet pipe and water outlet pipe that is connected with the hydraulic control water valve, and hydraulic control circuit is formed.This device is installed on the post alive of the hydraulic support that uses under the coal mine, can realizes the hydraulic support depositing dust, move frame, put in a skylight and put coal, manually follow the coal miner spray depositing dust, and can realize several connection spray depositing dusts, improved miner's operating environment greatly.But it is window and open coming into operation in a large number of tail boom hydraulic support along with covering beam behind the two transporters of colliery system, just above-mentioned two covering devices must be installed, and loosely organized, not compact if will realize the front and back auto spraying of hydraulic support.
The purpose of this utility model provides a nested structure compactness and makes the hydraulic support front and back device of atomizing de-dusting simultaneously.
For achieving the above object, existing atomizing de-dusting apparatus is improved, the hydraulic control water valve that will have a valve opening and a spool is improved to have two identical valve openings and adorns two identical spools, the inlet opening communicates with two valve openings, the external water inlet pipe in the inlet opening, adorn two covers in the valve body bilateral symmetry and have the outlet pipe of nozzle and by two hydraulic control pipelines, a reversible lock, two signal pipes, two fluid pressure lines that threeway is formed, wherein two threeways are contained on the preceding post of living of hydraulic support, on the cavity of resorption pipeline, in addition two threeways are contained on the post of living behind the hydraulic support, on the cavity of resorption pipeline.
Owing to take above-mentioned measure, behind two fortune machines, cover beam and window or open in the tail boom hydraulic bracket system, said apparatus is contained in the post upper and lower cavity pipeline of living before and after the support.When the needs support moves frame or put in a skylight the caving coal, can operate hydraulic control valve, the pressure fluid of drawing from the oil pipe of support front and back post upper and lower cavity alive passes to the hydraulic control water valve by signal pipe, reversible lock, hydraulic control pipe respectively, thereby spool in the promotion hydraulic control water valve separately moves.Because the inlet opening communicates with two valve openings, but then the both sides that are connected with valve body of break-make pass in and out the water route, reach the purpose of support both sides auto spraying depositing dust.And can adopt two or three connection sprays as required, form many water curtains, the dust that produces when eliminating hydraulic support work fully.
Below in conjunction with accompanying drawing embodiment of the present utility model is further specified.
Fig. 1 is the structure diagram of the utility model hydraulic pressure automation spray device for reducing dust;
Fig. 2 is the longitudinal plan of hydraulic control water valve among Fig. 1.
In Fig. 1, be connected to hydraulic control pipe 6 and 9 on the fluid hole, two ends, side of hydraulic control water valve 10, hydraulic control pipe 6 is connected with reversible lock 5 with 9 the other end, the opposite side of reversible lock be equipped with two bars pipes 3 and 4, two signal pipes respectively with support before the threeway 1 of living on the upper and lower cavity pipeline of post be connected with 2; In the middle of the hydraulic control water valve both sides, one is that water inlet pipe 19 is connected with the feed pipe of down-hole, and two is the outlet pipe 12 that the outlet pipe 7 of shower nozzle 8 is housed and shower nozzle 13 is housed in addition; Connect hydraulic control pipe 20 and 11 at the opposite side two ends of ripple water-control valve equally on by the liquid hole, the other end of two hydraulic control pipes is connected with reversible lock 14 again, the opposite side of reversible lock is equipped with two bars pipes 18 and 15, and respectively with support after the threeway 16 of living on the upper and lower lumen road of post is connected with 17, above-mentioned each manage the high-pressure rubber pipe of the band ready-packaged joint that all is the hydraulic support special use.
In the hydraulic control water valve sectional drawing of Fig. 2, valve body 10 has in two valve openings, 24,25, two valve openings identical spool all is housed, each spool is made of two parts, be cylindrical spool 21 and long handle spool 22, cylindrical spool 29 and long handle spool 26, spool are that 45 steel are through antirust nitrogen treatment.Two cannelures are arranged on the large cylinder external cylindrical surface of cylindrical spool 21,29 and long handle spool 22,26, double focusing tetrafluoroethene back-up ring and " O " RunddichtringO are housed in the groove.The special water seal that one nylon back-up ring and " O " RunddichtringO and polyamide skeleton constitute is housed on the shoulder between the big small cylinder of long handle spool, and by the fastening water seal of nut.Tightly there is screw plug at the two ends of valve opening.There are seven to connect the hole soon in the both sides of valve body.There is an inlet opening 28 centre, communicates with two valve openings, and what the centre was relative is two weep holes 23,27, all the other four is the fluid hole, feed liquor and fluid by the spool two ends move back and forth spool, make weep hole and inlet opening through and off to reach spraying and the purpose that stops to spray.
Claims (1)
