Detailed description of the invention
By reference to the accompanying drawings the specific embodiment of the present invention is described further.
Pick cutting test roller shutter type dust protective cover, comprise standing part, standing part comprises the wall of cutting test platform both sides and rear setting, roller shutter storehouse 9 is installed in the top of rear wall or the rear end at wall top, both sides, the top of both sides wall and the right-angle turning place of both sides wall are provided with some support rollers 12 parallel to each other, the both sides of the front facade of both sides wall are all provided with side locating slot 11 along on the vertical moving direction of roller shutter, testing stand forward lower part arranges roller shutter drives, described roller shutter drives comprises the drive motors 3 by the rotating of direction switch 6 control realization, bevel gear diverter 2, pulley 1 and steel wire rope 7, the output shaft of drive motors 3 connects the power shaft of bevel gear diverter 2, the output shaft two ends of bevel gear diverter 2 connect pulley 1 respectively, two pulleys 1 are all wound with steel wire rope 7, one end of steel wire rope 7 connects roller shutter 8.Arrange slide rail bottom the wall of cutting test platform both sides, wall and slide rail form slide mechanism.
Drive motors makes the transmission direction of axle change 90 degree by bevel gear diverter, and driven wheel of differential connects two pulleys by synchronizing shaft.When drive motors rotates forward, two pulleys rotate forward simultaneously, and by steel wire rope around on pulley, steel wire rope shortens, and roller shutter is drawn out, and forms a closed space together with other standing part of dust cover.
When test specimen needs to load testing stand, during drive motors reversion, rope stretch, roller shutter is regained by the spring be arranged in roller shutter storehouse, originally the position of roller shutter forms open cavity, and form the open space of both direction, test specimen lifts from bench top.The wall slide-open simultaneously of side, testing crew can enter thus, assists completing of hoisting process, and simultaneously after protective cover is opened, the open space easy access formed is safeguarded.After having lifted, protective cover is closed, and reaches the object preventing dust recycling, and such enclosure space can provide believable condition determination for measuring dust concentration.
