Description

Moving platform car special for vehicle service

The utility model relates to a kind of vehicle maintenance and repair with mobile trolley used, and it is used for supporting the car body of maintenance and this car body being transported to needed place.

General automobiles with mobile trolley used be to be used for dragging parking offense, this chassis can be mentioned car chassis, thereby the automobile of breaking rules and regulations to park can be dragged away, above-mentioned chassis includes supporting station, and its both sides are provided with wheel, and supporting station central authorities are provided with drawbar, when being located at automobile two vehicle wheel frames on this supporting station, car body weight puts on the supporting station, can carry out required dilatory action like this, and therefore above-mentioned mobile trolley used structure is very simple.

But for the car of et out of order, the above-mentioned mobile trolley used dilatory operation that can't be fit to, because general broken down vehicle, often to it be pulled on above the bogie (truck) by mobile trolley used, or it is pulled to maintenance platform top, when dilatory vehicle, this vehicle inclination angle may be quite big like this, if adopt above-mentioned mobile trolley used then very likely make the broken down vehicle that is stowed go up landing and get off from mobile trolley used.

All can produce car body for the vehicle that traffic accident takes place is out of shape because of collision, or the phenomenon that comes off of its single wheel, like this with above-mentioned general mobile trolley used can't drawing to it, because when car body is only supported by the wheel of a side, then can make car body generation deflection, thereby it is normally dilatory to carry out, and therefore says that the existing above-mentioned mobile trolley used maintenance vehicle of can't treating is drawn operation.

The purpose of this utility model is to provide a kind of vehicle maintenance and repair with mobile trolley used, and this chassis can be drawn operation under the situation of great slope.

Above-mentioned purpose is to realize with mobile trolley used by the vehicle maintenance and repair of following structure, this chassis comprises main support, this main support bottom is provided with a plurality of castors, the main support both sides are provided with the telescopic type wheel bearing support of adjustable width, vertically be provided with two cramp bars in the main support upper edge, be equipped with back plate on this cramp bar, this back plate is used for fixing the car body underframe.

The bearing support suit that is positioned at the main support both sides passes the two ends of the slide bar of main support, thereby the width of its supporting wheel of bearing support scalable, be respectively equipped with swing span in each bearing support both sides, this swing span is articulated on the slide bar, the swing span outside is positioned at the bearing support outside, and the swing span inboard is set on the above-mentioned slide bar that passes main support by sliding sleeve.

Be connected with chain between the above-mentioned swing span, this chain is fixed the wheel that is supported on the bearing support with swing span.

Be provided with a plurality of adjustment mounting holes on above-mentioned cramp bar, this hole is used for by latch back plate being installed in the differing heights of cramp bar.

The cramp bar lower end is connected with and its all-in-one-piece sliding sleeve, and this sliding sleeve is set on the pipe fitting in the main frame, and this sliding sleeve links to each other with another sliding sleeve by fixed link, and this another sliding sleeve is set on the slide bar.

Advantage of the present utility model be to transport traffic accident takes place or nonrunner vehicle, and when tilting of car body, still can draw operation and the phenomenon of automobile landing can not take place.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the transparent view of the utility model chassis;

Fig. 2 is the lateral plan that sets up the utility model chassis of automotive wheel;

Fig. 3 is fixed in the lateral plan of the utility model chassis of the state on the automobile chassis frame for back plate is in.

As shown in Figure 1, the utility model is mobile trolley used to be tubular structure, in central authorities is main support 10, main support 10 belows are provided with a plurality of castors 11, main support 10 both sides are respectively equipped with the telescopic bearing support 12 of adjusting width, on these support frame 12 suit slide bars 13, so just can be and the spacing of bearing support 12 is adjusted according to the wheel axial extent of the vehicle that will drag, bearing support 12 front and back are respectively equipped with swing span 14, this swing span 14 is articulated on the slide bar 13, the outside of swing span 14 is positioned at the outside of bearing support 12, and its inboard is sleeved on the slide bar 13 in the main support 10 by sliding sleeve 15, can make swing span 14 in bearing support 12 front and back sideway swivels swings like this, thereby wheel is fixed by chain 23, in addition, also can limit the degree that two-side supporting frame 12 moves laterally, thereby the unlikely bearing support 12 that makes skids off from main support 10 both sides.

As shown in the figure, vertically be provided with two cramp bars 16 in main support 10 upper edges, this cramp bar 16 is sleeved on the pipe fitting of main support 10 by sliding sleeve 18, such two cramp bars 16 can be adjusted its spacing, cramp bar 16 is provided with a plurality of adjustment mounting holes 19, back plate can be installed in the differing heights of cramp bar 16 like this by latch, thereby the underframe height that adapts to different automobile types, main support 10 central-front side are provided with draw bar 22, and this bar 22 can be pulled on bogie with nonrunner vehicle or above the maintenance platform by winch.

As shown in Figure 2, when nonrunner vehicle being installed in mobile trolley used going up, at first to use hoisting crane (jack) with automobile jack-up, simultaneously the swing span 14 of bearing support 12 sides of chassis both sides is set level, and pass to automotive wheel 30 belows, at this moment automotive wheel 30 is satisfied with the top of bearing support 12, then rotate rocker 14 and swing span 14 is locked position shown in the figure by chain 23, wheel 30 stably is set up in the bearing support 12, consequently, even run-off the straight phenomenon when dilatory, above-mentioned wheel 30 can be from landings on the bearing support 12 yet.

As shown in Figure 3, mobile trolley usedly can when dragging vehicle, to have stable fixed effect in order making, on main support 10, to be equipped with cramp bar 16, back plate 20 is housed on it, this back plate 20 on automobile chassis frame 31, so just can make the mobile trolley used car body that stably supports by bolt.The chassis of said structure also can be used to drag the vehicle that wheel comes off or car body is out of shape because of bumping.

As can be seen from Figure, cramp bar 16 is provided with a plurality of adjustment mounting holes 19, this hole is used for back plate 20 is assemblied in the differing heights of cramp bar 16, cramp bar 16 lower ends are connected with all-in-one-piece sliding sleeve 18, it is set on the pipe fitting in the main support 10, this sliding sleeve 18 links to each other with another sliding sleeve 18 by fixed link 17, and this another sliding sleeve 18 is set on the slide bar 13 of main support 10.Because said structure can be adjusted the relative position of two cramp bars 16 on bearing support 10, thereby adapts to the screwhole position of different automobile chassis frames 31, sliding sleeve 18 links to each other with fixed link 17, can make supporting member 16 be in plumbness.

Two bearing supports 12 in the utility model can be adjusted relative position, thereby can be fit to different vehicles.Swing span 14 and chain 23 match, and automotive wheel 30 can be firmly fixed.And the structure of supporting member 16 and back plate 20 can make mobile trolley used and car body underframe 31 fuses, thereby makes it more firm when drawing operation, and can be used for the vehicle that dilatory wheel comes off or deforms.The position of two cramp bars 16 can be adjusted, thereby can adapt to the width of different automobile chassis frame 31.
