Abstract
The utility model discloses a built-in wheel set lifting device, which comprises a lifting seat arranged on a frame girder of a railway vehicle and a lifting plate connected with the lifting seat. The lifting plate is connected onto a wheel set shaft box. The lifting seat is arranged inside the frame girder. The lifting seat is provided with a protruding lifting hook. The lifting hook perforates into a rectangular lifting hole of the lifting plate. The built-in wheel set lifting device has a simple design thought and is convenient to apply. The problem of large occupied space of the original structure can be rapidly effectively solved. The difficulty in assembly check is reduced. The production efficiency of a bogie is greatly improved. The manufacturing cost and the human resource are saved. The safe operation of the vehicle can be guaranteed.
Description
Technical field
The utility model relates to a kind of built-in wheel lift, and the wheel that a kind of rail vehicle truck of saying so is accurately used is to lift.
Background technology
It is between vertical damper 7 and the journal box spring 8 that original steering framing wheel is arranged on one to lift 9, as shown in Figure 3 and Figure 4, the three is in one line on the bogie truck longitudinal direction, this mode makes the space anxiety at this position, it is big to take up room, not only taken the gap on the bogie truck longitudinal direction, and the space is narrow and small, be not easy to assembling, check, when check finding that the gap is too small or interfering, be not easy to handle, can handle interference or little position, gap after must decomposing a whole set of single stage suspension device.In addition, because during the welding of framework end lifting seat and truck side sill,, be difficult to assembly welding and be easy to generate weld defect because this position weld seam is many, the space is little.Owing to make cumulative limit, occur easily between pivoted arm and the framework lifting seat interfering; Assembling quality is difficult to guarantee that cause and do over again, production efficiency reduces, and has brought certain difficulty for the manufacturing of bogie truck.
The utility model content
Technical problem to be solved in the utility model is, overcomes the shortcoming of prior art, and a kind of built-in wheel lift is provided, can keep the original design function, reduced vertical leading dimensions of bogie truck, saved manufacturing cost and human resources, and can guarantee vehicle operating safety.
In order to solve above technical matters, the utility model provides a kind of built-in wheel lift, comprise lifting seat that is arranged on the guideway vehicle frame girder and the lifting plate that links to each other with described lifting seat, described lifting plate is connected wheel on the axle box, described lifting seat is installed in described frame girder inboard, described lifting seat is provided with the suspension hook that stretches out shape, and described suspension hook penetrates in the lifting hole(eyelet) of described lifting plate.
The technical scheme that the utility model further limits is:
For the easy for installation and structural strength that guarantees that lifting is done, aforesaid built-in the wheel to lift, described lifting seat by six roots of sensation bolted connection at least in described frame girder inboard.
Further, aforesaid built-in the wheel to lift, the lifting hole(eyelet) of described lifting plate is a rectangular through holes, makes things convenient for being connected of lifting seat and lifting plate, also helps the height adjustment of journal box spring.
The beneficial effects of the utility model are: the utility model mentality of designing is simple, and it is convenient to use, and can solve original design quickly and effectively and take up room greatly, be that the spacing of vertical damper and journal box spring reduces to 245mm by 270mm with original one; Reduced the difficulty that assembling is checked greatly, improved bogie truck production efficiency, saved manufacturing cost and human resources, and can guarantee vehicle operating safety.

Fig. 3 is original promoting or transferring apparatus structure front view.
Fig. 4 is original promoting or transferring apparatus structure birds-eye view.
The specific embodiment
A kind of built-in wheel that present embodiment provides to lift, structure as depicted in figs. 1 and 2, comprise lifting seat 2 that is arranged on the guideway vehicle frame girder 1 and the lifting plate 3 that links to each other with described lifting seat 2, described lifting plate 3 is connected wheel on the axle box 4, described lifting seat 2 is installed in described frame girder 1 inboard by eight bolted connections, described lifting seat is provided with the suspension hook 5 that stretches out shape, and described suspension hook 5 penetrates in the oblong lifting hole(eyelet) 6 of described lifting plate.
Later-model bogie truck is built-in takes turns lift on the basis of holding device original function, makes that by the change design wheel is simple in structure to the axle box lift, is easy to installation, examination and maintenance.Farthest reduce this position amount of doing over again, improved production efficiency, reduced manufacturing cost and human resources consumption.The novel steering frame is built-in takes turns lift by shift in position is set, and rearranging one is to survey in the vertical damper, simpler, reliable than original design, easy to assembly.Owing to simple than original design, can observe directly whole parts of this structure from the bogie truck end, made things convenient for assembling, examination and maintenance.
In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection domain of the utility model requirement.
