Detailed description of the invention
See Fig. 1-5, the present invention relates to a kind of closed-type trailer up-down movable top cover, comprise roof skeleton 1, glass epoxy 2, aluminium layering 3, side wall frame 4, the outer beam 5 of telescopic boom, telescopic boom inner beam 6, wear-resistant slide block 7, elevating ram 8, cylinder pedestal 9, point flow throttle valve 10 and hydraulic directional control valve 11.
Roof skeleton 1 is welding rigid construction, and roof skeleton 1 surrounding is welded as truss structure by 40*40*2.5 rectangular tube, alleviates the weight of top cover like this while ensureing top cover rigidity,
Roof outer panel adopts the light materials such as glass epoxy, glass epoxy 2 is pressed on top cover outside face by rivet aluminium layering 3, and riveted joint place and aluminium layering 3 gap place all oiling sealant prevent from leaking, and side wall frame 4 is welding rigid construction, steel plate and rectangular tube is adopted to be welded on vehicle frame surrounding
Cylinder pedestal 9 and the outer beam 5 of telescopic boom are fixed by welding in side wall frame 4 left and right sides.The outer beam 5 of telescopic boom and telescopic boom inner beam 6 match composition moving sets, promote telescopic boom inner beam 6 by elevating ram 8 to move along the outer beam 5 of telescopic boom, thus realize the lifting of top cover, telescopic boom is outer is equipped with wear-resistant slide block 7 between beam 5 and telescopic boom inner beam 6, wear-resistant slide block 7 material is engineering plastics, and this material has that wear resisting property is good, friction coefficient is little, the feature of difficult high temperature, can reduce friction drag when telescopic boom inner beam 6 moves, lifting mechanism is run more reliable, longer service life.Point flow throttle valve 10, hydraulic directional control valve 11 are connected with elevating ram 8 by hydraulic tubing, and divide flow throttle valve 10 for ensureing the synchronism that elevating ram 8 is elevated, hydraulic directional control valve 11 is for controlling the liter of elevating ram 8 and falling.
See Fig. 6, when removable top cover rises by needs, the control handle of operation hydraulic directional control valve 11, pressure oil splits into three tunnels and enters three points of flow throttle valves 10 after change-over valve 11, the large chamber that six tunnels enter six elevating rams 8 is split into again through three points of flow throttle valves 10, flow is controlled by a point flow throttle valve 10, ensure that the pressure oil flow entering each elevating ram 8 is basically identical, the piston rod realizing six elevating rams 8 synchronously rises, the piston rod of elevating ram 8 promotes telescopic boom inner beam 6 and moves up along the outer beam 5 of telescopic boom, together with the top of telescopic boom inner beam 6 is bolted with roof skeleton 1, when telescopic boom inner beam 6 moves up, roof skeleton 1 also rises movement, thus achieve the rise of removable top cover.Unclamp the control handle of hydraulic directional control valve 11, the spool of hydraulic directional control valve 11 gets back to meta, utilizes spool meta locked and the function of off-load oil-feed, the direct oil return of pressure oil, and hydraulic oil in elevating ram 8 is locked, realizes removable top cover and stop rising, and locked in this position.
When removable top cover is fallen by needs, the control handle of operation hydraulic directional control valve 11, pressure oil gives the loculus fuel feeding of elevating ram 8 equally through hydraulic directional control valve 11 and point flow throttle valve 10, the piston rod of elevating ram 8 is retracted, the piston rod of elevating ram 8 drives telescopic boom inner beam 6 and roof skeleton 1 to decline, realizes the decline of movable decking.
