Abstract
The utility model belongs to an automatic spraying and water supplying device for an underground belt conveyer in a coal mine, which is composed of a lever combined loading mechanism and a one-way control valve. The utility model is an automatic control water supplying device which is suitable for a belt conveying system, and is used for sprinkling water to drop dust for preventing dust from flying in the process that the belt conveying system conveys incompact materials. The utility model is particularly suitable for sprinkling water and spraying fog on the transfer points and the unloading points of the underground belt conveying system in a coal mine in the process of conveyance, and is an ideal automation control water supplying device for sprinkling water, dropping dust, reducing temperature and extinguishing fire.
Description
At present, underground mine use is in the automatic spray control device of belt transportation system, can be divided into two classes, one class is the spray control device with dynamo-electric principle of combining development, the disadvantage of this series products is the signal conversion adopted and influenced by subsurface environment bigger for signal amplification circuit, cause reliability relatively poor, and installation, maintenance are big.In addition, another weak point is the spray control device of this principle development, realize supplying water, cutting off the water by a kind of explosion-proof solenoid valve, because electromagnetic valve is prone to fault (influencing performance and life-span and hydraulic pressure coupling etc. as aqueous corrosion) equally.Therefore, this control system rate of breakdown height tripping usually occurs and makes situation, and it is feasible to make it not reach stable performance; Another kind of is the automatic spray control device of developing with hydraulic principle.A kind of small-sized hydraulic system has been adopted in this device inside.During work, operation drives the drive rotation of controller by conveyor, with the internal hydraulic pressure system works of driving governor, its inner water-supply valve is opened automatically, realizes auto spraying.Utilize the major defect of the controller of hydraulic principle development to be: because controller relies on conveyor operation drive work fully, the rotating speed of drive is subjected to the influence of the conveyor speed of service, because the conveyor speed of service is very fast, generally about 2.5m/s, even bigger (occurring about 3m/s), can not guarantee in addition in time to inject lubricating oil to controller internal hydraulic pressure system, driving mechanism (wheel) wearing and tearing to the hydraulic system that makes this device are severe, seriously influenced the application life of this class device, therefore, be not used widely as yet.
The purpose of this utility model is to overcome at present the deficiency of spray control device automatically, and a kind of mechanical auto spraying water supply installation is provided.
The purpose of this utility model is achieved in that the shell of a controller, and delivery port, water inlet are arranged on the shell, spring is arranged and withstand a steel ball on the water inlet pipe in the water inlet, and peace one push rod in the post chamber of steel ball opposite side, push rod one end exposes outside the shell; Bracing frame upper hinge at housing connects a lever, and push rod is withstood in the lever lower end, and lever top is connected with spring, and the spring other end is fixed on the housing, and the lever other end is equipped with wheeled contact.During use controller is loaded on the belt bottom, will the bar thick stick be depressed by wheeled contact when the belt heavy duty, the lever other end promotes push rod and backs down steel ball, and water promptly enters from water inlet, flows out from delivery port.When belt was unloaded, lever set back by spring, and steel ball is blocked water inlet by spring, interrupted supplying water.When the load-carrying of belt changes, by lever, the open gap of steel ball is also changed thereupon, adjusted output.
The utility model has the advantages that: simple and practical on the operating principle, meet the production environment requirement, reach the trade management requirement of " the many sprays of heavy duty, underloading are sprayed less, zero load do not spray ", and have stable and reliable for performance, easy for installation, maintenance is little, long service life, energy-saving safe, lower-price characteristic.
Engage description of drawings the utility model embodiment below.Accompanying drawing is the internal construction sectional drawing of the controller that provides according to the technical scheme that is provided.
Among the figure, 1-outlet pipe, 2-water inlet O RunddichtringO, 3-control valve spring; The 4-water inlet pipe, 5-control valve steel ball, 6-support bar, 7-spring, 8-application valve body; the 9-push rod, 10-O RunddichtringO, 11-top stem casing, 12-lever, the wheeled contact of 13-; the 14-fixed axis, 15-loads wheel, 16-O RunddichtringO, 17-O RunddichtringO; the 18-O RunddichtringO, 19-control valve housing, 20-adjusts bolt, 21-fixed base plate; the 22-axle, 23-end cap, 24-spring protection cover, 25-pull bar; the 26-axle, 27-axle, 28-bracing frame, 29-shifting axle
In the drawings, water inlet and delivery port have been done on the control valve housing 19, after water inlet is installed water inlet pipe 4, O RunddichtringO 2 seals water inlet, spring 3 holds out against steel ball 5 on the water inlet of application valve body 8, make control valve be in the state of " breaking ", application valve body 8 utilizes O RunddichtringO 18 that itself and mating holes are sealed, O RunddichtringO 10 is housed on the top stem casing 11, itself and mating holes are sealed, push rod 9 is arranged in the application valve body 8, bracing frame 28 is installed, the lever combination load maintainer is installed on bracing frame 28 on push rod the right.This mechanism is that the end at lever 12 is connected with one group of spring mechanism; In spring mechanism; its pull bar 25 can rotate by the axle 26 on lever 12 1 ends; and can overlap in 24 at spring protection and move; between protective sleeve 24 and pull bar 25, spring 7 is housed; end at protective sleeve is equipped with end cap 23, and end cap 23 can rotate around axle 22, and axle 22 supported bars 6 are fixed on the housing 19; the effect of spring mechanism is that wheeled contact 13 is automatically reset when suffered load disappears, and makes control valve be in " breaking " state.Lever 12 1 ends have wheeled contact 13, and its fulcrum is by fixed axis 14, and hinge is connected on the bracing frame 28.Have translot on the bearing support 28, shifting axle 29 is arranged in the groove, axle 29 puts and loads wheel 15; Housing is welded on the base 21, has on the base 21 to adjust bolt 20, is used to adjust the loading gap with travelling belt.When plus load acts on the wheeled contact 13, wheeled contact 13 will move down and rotate around axle 27, lever 12 combination load maintainers are rotated around fixed axis 14, load is added on section wheel 15, load wheel 15 and rotate around shifting axle 29, shifting axle 29 moves horizontally, and loading is on top board 9 the most at last, push rod 9 promotes steel ball 5 makes it separate with application valve body 8, when this moment, control valve was in " leading to " state.O RunddichtringO 16,17 is housed on the push rod 9, and anti-sealing flows out from hole, the right along push rod.When control valve was in " leading to " state, water flow to from water inlet, flowed out from delivery port, and delivery port is equipped with outlet pipe 1 and is connected with atomization mechanism.
