For solving the lubrication problem of each gear and bearing, the utility model carries out the circulatory system of forced feed lubrication to gear and bearing.Casing also is provided with motor outward, the output shaft of motor connects oil pump, the oil pump inlet port is communicated with box house by fuel sucking pipe, the oil pump oil-out connects a minute oil clot, divide oil clot to connect the oil pipe of some roads parallel connection, each oil pipe port of export connects atomizer, and each atomizer is arranged at each bearing and gear engagement vice division chief.The driven by motor pump rotates, by fuel sucking pipe oil suction from casing, the oil that is drunk up forms the multi-channel parallel oil circuit by minute oil clot, be assigned on the atomizer by relevant again, on atomizer all bearings and engaging tooth wheel set with the gear oil injection, when guaranteeing gear-box work, all bearings and gear all can obtain good effectively lubricated.
Described pedestal is the convex shape structure, the building stones clamping device is installed in the narrow position of pedestal one side, as shown in figure 10, these side group seat both sides and inboard arrange wall, the roller shutter storehouse is installed in the top of inboard wall or the rear end at wall top, both sides, the right-angle turning place of the top of both sides wall and both sides wall is provided with some support rollers parallel to each other, the both sides of both sides wall are along all being provided with the side locating slot on the moving direction of roller shutter, the testing stand outer lower portion arranges roller shutter drives, described roller shutter drives comprises the roller shutter drive motors of realizing rotating by direction switch control, the bevel gear diverter, pulley and steel wire rope, the output shaft of roller shutter drive motors connects the power shaft of bevel gear diverter, the output shaft two ends of bevel gear diverter connect respectively pulley, all be wound with steel wire rope on two pulleys, an end of steel wire rope connects roller shutter.The roller shutter drive motors makes the transmission direction change degree of axle by the bevel gear diverter, and driven wheel of differential connects two pulleys by synchronizing shaft.Two pulleys forward rotation simultaneously when roller shutter drive motors forward rotation, on pulley, steel wire rope shortens with steel wire rope, and roller shutter is drawn out, and forms the space of a sealing with other standing part of dust cover, as shown in figure 11.
When test specimen need to be packed testing stand into, during the counter-rotating of roller shutter drive motors, rope stretch, the spring that is installed in the roller shutter storehouse is regained roller shutter, originally the position of roller shutter forms open cavity, forms the open space of both direction, and test specimen lifts from the experimental bench top.The wall of side is slide-open simultaneously, and testing crew can enter thus, assists finishing of hoisting process, and after protective cover was opened, formed open space easy access was safeguarded simultaneously.After lifting was finished, protective cover was closed, and reached the purpose that prevents the dust diffusion, and such enclosure space can provide believable condition determination for measuring dust concentration.
The utility model has realized requiring the motor function of relative complex with simple drive method.Owing to require to form the fully open of two adjacent surfaces at testing stand, therefore to protect dust from both direction, on vertical plane, to overcome the weight of protective cover self, on horizontal plane, will overcome the flexible deformation of protective cover self, and reliable in the seam crossing sealing property.The roller shutter dust cover can seal and open test space with the form of integral protection cover, and can realize that integral protection covers on two continuous motions on the vertical plane, has solved the poor problem of seam crossing sealing.
When avoiding roller shutter to move and other protective plate produce friction and cause roller shutter to damage, at the protective plate that moves horizontally direction and right angle turn of roller shutter several support rollers are installed.These rollers are propped roller shutter, and a little more than protective plate, have avoided roller shutter to be broken owing to the excessive roller shutter that causes of resistance in moving process.
In order to make roller shutter play hermetic effect to the dust that cutting test produces, on the moving direction of roller shutter, the side locating slot has been installed, roller shutter just can pass through from the side locating slot, and very little with the gap of side locating slot, can reach the effect that prevents the dust diffusion.
When roller shutter is pulled out fully, when forming the test space of sealing, motor quits work.At this moment, the spring assembly in the roller shutter storehouse can retract roller shutter.For preventing that roller shutter is pulled, the closure of guarantee test environment is offered a circular hole at synchronizing shaft, and circular hole is installed a tapered dowel outward.After the roller shutter drive motors stops, under the effect of roller shutter storehouse inner spring, roller shutter can be to reclaiming contracting, cause synchronizing shaft oppositely slowly to rotate, when the circular hole on the synchronizing shaft aligned pin, pin fell into circular hole, and synchronizing shaft is connected with fixture, stoped the rotation of synchronizing shaft, roller shutter is reliably fixed.
When roller shutter need to be opened, pin is extracted, restart the roller shutter drive motors, under the effect of roller shutter storehouse spring, roller shutter can be taken in the roller shutter storehouse automatically.
