Embodiment
Below in conjunction with accompanying drawing and specific embodiment the present invention is explained further details, following explanation only is exemplary, so that those skilled in the art better understand the present invention.
Load and protective device like Fig. 1,2,3, a kind of heavy-duty car test shown in 4, comprise auxiliary girder 1, big container 2, little container 3, support 4 and two support wheels 8, wherein said auxiliary girder 1 links to each other with the instruction carriage vehicle frame, and width is consistent with the instruction carriage frame width; Big container 2 be a charger with little container 3, is installed in auxiliary girder 1 top, be used for loading to instruction carriage, and little container 3 is arranged on the front, and big container 2 is arranged on the back, when satisfying loading to the adjustment of instruction carriage centre of gravity place; Support 4 is a protective device with support wheel 8, and said support 4 is across above auxiliary girder 1, and two support wheels 8 all are installed in support 4 two ends respectively through connector, and connector and 4 one-tenth on support and the consistent angle a of instruction carriage rollover angle.
Consider the difference of terrain clearance when different automobile types is overturned; Said connector is the structure of adjustable in length; Comprise first connector 13 that links to each other with support 4 and second connector 12 that links to each other with support wheel like Fig. 4,5, said connector shown in 6; Said first connector 13 and second connector 12 are pegged graft and are one, and the surface all has a plurality of bolts hole 15, actual processing for ease first connector 13 and second connector 12 select for use can socket square steel.
Said auxiliary girder 1 as shown in Figure 4 has two channel-section steels that are arranged in parallel and the crossbeam between two channel-section steels 10, and the channel-section steel height can be decided according to heavy-duty car vehicle frame size and car load height.
Said little container as shown in Figure 3 links to each other with auxiliary girder 1 through some plate bodys 7 with big container, and links to each other with support 4 through L shaped plate body 6.
Consider the firm shape of cost and structure; Like the said support 4 of Fig. 5 is square steel; And the top is provided with by square steel and constitutes truss 14, and said support 4 links to each other with auxiliary girder 1 with web joint 9,11 through two U bolts 5, and said web joint 9,11 is L shaped; Its vertical component links to each other with auxiliary girder 1, and horizontal component links to each other with support through U bolt 5.
The actual installation process is following: auxiliary girder 1 is fixed on the automobile frame; According to car load center of gravity, each parts weight and want the distribution situation of loaded load to calculate centre of gravity place; With support 4 traverses on auxiliary girder 1; Be positioned at the centre of gravity place of automobile on the longitudinal direction, through U bolt 5 and web joint 9,11 that support 4 is fixing with vehicle frame auxiliary girder 1.Little container 3 is placed in support 4 the place aheads, and big container 2 is placed at the rear, leaves the distance of 400mm between the big or small container, and big or small container is connected fixing with support 4 through L shaped plate body 6, is connected fixing with vehicle frame auxiliary girder 1 through plate body 7.
The present invention can regulate according to frame width, centre of gravity place, the chassis height of different automobile types, has high generality.The two kinds of vehicles of HOWO and SCANINA of giving an example are used the process of this device; Two kinds of vehicles are all 6x4 and drive pattern; Wheelbase is all 3200mm; Chassis height, frame width difference, auxiliary girder 1 need design according to the concrete condition of vehicle technical parameter with plate body 7 during two kinds of vehicles tests, and miscellaneous part can be general.
Need to measure the width of vehicle frame before installing, the car load height of chassis above ground, cabin rear wall is the length of vehicle frame backward, calculates the centre of gravity place of full load car load, and the secure side degree of tilt of car load calculates support wheel wheel distance overhead.
HOWO instruction carriage frame width is 850mm, according to cabin rear wall backward the length of vehicle frame make auxiliary girder 1, auxiliary girder 1 width is fixed in auxiliary girder 1 on the instruction carriage vehicle frame with the instruction carriage frame width; In the vertical as much as possible near the centre of gravity place of full load car load; Earlier support 4 and support wheel 8 are in the same place through bolt, then with support 4 traverses on auxiliary girder 1, and stride across support 4 through U-bolt 5 and connect, fix, thereby support 4 and auxiliary girder 1 are fixed together respectively at web joint 9,11; At forward and backward little container 3, the big container 2 installed respectively of support 4, the distance at container and support 4 centers is 200mm at interval, through plate body 7 container and auxiliary girder 1 is linked together, and through L type web joint 6 container and 4 further connections of support is fixed simultaneously.After each parts connection is fixing, adjust 8 ground clearance of machine of support wheel, the distance on support wheel and ground is remained between 150mm～170mm through the connector 12 and the connector 13 corresponding spiro keyhole positions of support 4 that change support wheel 8.
SCANINA instruction carriage frame width 770mm, design auxiliary girder 1, the auxiliary girder width is fixed in auxiliary girder 1 on the instruction carriage vehicle frame with the instruction carriage frame width, and installing and fixing with the HOWO instruction carriage of other each parts installs and fixes mode.Adjust support wheel at last during the ground clearance of machine, guarantee that the distance on support wheel and ground remains between 130mm～150mm.
