Description
Technical field
The utility model relates to vehicle performance test technical field, is specifically related to a kind of driver's cab turnover test unit.
Background technology
A kind of new model pilothouse first need do roll-over test, whether enough to verify the structural strength of the bearing that pilothouse is connected with chassis, requirement checks whether support part has damage after doing 1000 rotary movements, whether the weld seam that bearing is connected with pilothouse has damage, and therefore needing provides a set of device completed needed for this test.
Utility model content
The utility model provides a kind of test unit, can complete the roll-over test of new model pilothouse first equipment.
Its technical scheme is: the front support seat, cylinder support and the flitch that comprise pedestal, electric oil pump, fluid pressure line, major-minor oil cylinder and be located on pedestal, described cylinder support is located between flitch and front support seat, front support seat and cylinder support are fixed on pedestal, front support seat and major-minor cylinder upper end are hinged with pilothouse respectively, major-minor oil cylinder lower end and cylinder support hinged, described electric oil pump is located in pedestal, and electric oil pump is connected with major-minor oil cylinder by fluid pressure line.
As preferably, described major-minor oil cylinder and front support seat include at least two, arrange respectively along the direction perpendicular to driver's cab turnover face.
As preferably, be provided with flitch mounting groove between described pedestal and flitch, described flitch mounting groove is fixed on pedestal.
As preferably, described electric oil pump is the oil pump of direct current 24V power drives, which is provided with operating switch and reversal valve.
The beneficial effects of the utility model are: this apparatus structure is simple, easy to operate, can complete the roll-over test to pilothouse, improve test efficiency, save human cost.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.
As shown in Figure 1, the present embodiment comprises pedestal 1, electric oil pump 2, fluid pressure line 3, major-minor oil cylinder 7 and is located at front support seat 6, cylinder support 8 and the flitch 4 on pedestal, cylinder support 8 is located between flitch 4 and front support seat 6, front support seat 6 and cylinder support 8 are fixed on pedestal 1, front support seat 6 and major-minor oil cylinder 7 upper end hinged with pilothouse 5 respectively, major-minor oil cylinder 7 lower end and cylinder support 8 hinged, electric oil pump 2 is located in pedestal 1, and electric oil pump 2 is connected with major-minor oil cylinder 7 by fluid pressure line 3.
In the present embodiment, major-minor oil cylinder 7 and front support seat 6 are two, arrange respectively along the direction perpendicular to driver's cab turnover face.
In the present embodiment, be provided with flitch mounting groove 9 between pedestal 1 and flitch 4, flitch mounting groove 9 is fixed on pedestal 1.
In the present embodiment, electric oil pump is the oil pump of direct current 24V power drives, which is provided with operating switch and reversal valve.
The principle of work of this device:
Electric oil pump is by 24V DC power supply, during test, the reversal valve of electric oil pump is first rotated extremely upwards upturned position by operating personnel, press play button, electric oil pump is started working, drive major-minor oil cylinder to protrude upward promotion pilothouse to overturn around front support seat upper end hinge, after turning to assigned position, operating personnel unclamp play button, electric oil pump quits work, reversal valve is rotated the position to upset downwards, press play button, oil pump is started working and is driven major-minor oil cylinder retraction to drive pilothouse to overturn downwards, driver's cab turnover unclamps play button to during horizontal level, electric oil pump quits work, a upset cycle completes.The above operation of circulation can complete roll-over test.
In the present embodiment, flitch is used for providing support rear cabin, reduces the impact to pedestal when pilothouse falls.
