Abstract
The invention provides the automatic balance decompression device used for new pattern gas cushion conveyor. The device can be used for port and quay gas cushion conveyor. The device is installed on the middle of groove under conveyer belt. The device comprises decompression barrel, motion mechanism and piston air valve composed by piston and gas outlet, the upper end of motion mechanism is contacted with conveyer belt, and the lower end of it is connected with piston. Between the device and conveyer belt there is rolling friction, saving the energy source, so the gas cushion conveyor runs placidly and reliably. The device has the advantages of self-adjusting gas film thickness, non abrasion, and simple structure.
Description
Technical field:
The invention provides a kind of later-model air cushion-belt conveyer air-sprung self-equalizing pressure relief device.Only there is friction of rolling between this device and the load-transfer device, energy savings, pressure release in time prevents " ribbon " phenomenon, and air cushion-belt conveyer is operated steadily, reliably.Can be widely used on the air cushion-belt conveyer of harbour, harbour.
Background technology:
Air cushion-belt conveyer have operate steadily reliable, running resistance is little, energy consumption is low, loaded area increases, advantages of simple structure and simple, thereby be widely used.Because conveyer is different when required air film supporting power is with heavy duty when zero load, particularly when underloading (or unloaded), the air cushion carrying is lighter but in actual applications.Gas easily floats load-transfer device middle part, and a large amount of gases of air-sprung are along vertical discharge (being called " ribbon ") of band, cause the load-transfer device dual-side sagging and with the friction of dish groove, in the service life of having reduced load-transfer device, also wasted the energy.
Summary of the invention:
The present invention seeks to overcome the shortcoming of prior art, a kind of self-equalizing pressure relief device of later-model air cushion-belt conveyer is provided.This device has the automatically regulating air-film thickness, do not have wearing and tearing, simple in structure, cut down the consumption of energy, guarantee advantages such as air cushion-belt conveyer operates steadily.
The technical scheme that realizes above-mentioned purpose is:
The present invention is arranged in the middle of the dish groove of belt conveyor bottom of rim strip formula conveyer, the piston air valve that it is characterized in that comprising the pressure release cylindrical shell, is positioned at its inner kinematic mechanism moving up and down and forms by piston and air extractor duct, wherein the upper end of kinematic mechanism contacts with belt conveyor, and the lower end links to each other with piston.
Wherein said kinematic mechanism by the roller that contacts with belt conveyor, top link to each other with roller strut bar that the bottom links to each other with piston and be enclosed within the spring on the strut bar, the spring divider that is positioned on the pressure release cylindrical shell is formed.
Wherein said piston adopts inverted U-shaped piston.
It is that the roller of strut bar one end changes with the change of load-transfer device that the present invention utilizes the elastic force of spring, play the probe gas film thickness, the effect of roller is to be friction of rolling between load-transfer device and the strut bar, the inverted U-shaped piston air valve and the strut bar other end of bottom link, and make the aperture of air outlet valve relevant with the thickness of air film.
Advantage of the present invention is aspect structural arrangement, consider the constructional feature of air cushion-belt conveyer, this device is arranged in the centre of coiling groove, install very convenient, and overcome the adjusting shakiness that original adjustable pipe pressure relief device brings, the friction problem between load-transfer device and the adjustable pipe sealing collar extension.And adopt inverted U-shaped piston air valve can guarantee the smooth transition of air film, make the opening of blowdown valve have the air-film thickness between load-transfer device and the dish groove to come linear the adjustment.
Description of drawings:
Fig. 1 is a structural representation of the present invention.

Specific implementation:
The present invention is further described below in conjunction with Fig. 1.
As shown in the figure, the present invention is arranged on dish groove 2 centres of belt conveyor 1 bottom of rim strip formula conveyer, it comprises pressure release cylindrical shell 3, and the piston air valve that is arranged in the kinematic mechanism of pressure release cylindrical shell 3, forms by inverted U-shaped piston 9 and air extractor duct 10, wherein by the roller 4 that contacts with belt conveyor 1, top link to each other with roller 4 strut bar 5 that the bottom links to each other with inverted U-shaped piston and be enclosed within the spring 7 on the strut bar 5, the spring divider 6 that is positioned on the pressure release cylindrical shell 3 is formed kinematic mechanism moving up and down.
When air film conveyer by static to the blowing air-blowing, when setting up air film and normal operation gradually, the self-equalizing pressure relief device of air cushion-belt conveyer is in closed condition, have only when the load on the load-transfer device changes and cause air-film thickness to exceed normal range, because roller 4 remains under the effect of spring 7 and the contacting of load-transfer device 1, the variation of air-film thickness will be detected, the variation of air-film thickness will cause opening the venting valve by inverted U-shaped piston 9 upward movements of strut bar 5 bonded assemblys, owing to be inverted U-shaped piston air valve, the opening of its valve is opened gradually, gas unnecessary in the upper chamber flows out by the air extractor duct 10 of U-shaped mouth below pressure release cylindrical shell 3, help keeping the stability of air film variation, prevented the generation of ribbon phenomenon again, guaranteed that air film conveyer normally moves.
