Abstract
The utility model relates to the field of semitrailer designing and manufacturing, in particular to a semitrailer towing plate lifting device which comprises a towing plate, a cargo carrying table, a fixing plate, a guide column and a sleeper. The towing plate is fixedly connected with the cargo carrying table. A guide hole matched with the guide column is formed in the towing plate. The guide column is arranged on the fixing plate. The fixing plate is fixedly connected with a towing seat of a tow tractor. The sleeper is arranged between the towing plate and the fixing plate. At normal traveling time of a semitrailer, the sleeper can support the towing plate, and a guide shaft is used for locating the towing plate. When the trailer needs to pass through a tunnel or is on other special road conditions, the sleeper is detached, so that the height of the towing plate descends 20-30cm, and the height of the cargo carrying table also descends 20-30cm. Compared with the prior art that a towing plate is welded on a towing seat of a tow tractor, the height of the towing plate of the semitrailer towing plate lifting device can be adjusted so as to adapt to special road conditions such as tunnels.
Description
Technical field
The utility model relates to superimposed trailer and manufactures and designs field, especially a kind of semitrailer towing plate jacking system.
Background technology
At present, people often can use superimposed trailer, and in the time using superimposed trailer; especially when transporting overheight cargo and crossing tunnel or other special road conditions; while exceeding top, tunnel due to cargo height, need to reduce loading platform height, the height of loading platform is generally by being that towing plate regulates.The towing plate of product has plenty of on the traction seat that is welded on tractor truck at present, and its height can not regulate, transportation when loading platform height can not be applicable to special road conditions.This is the existing weak point of prior art.
Utility model content
The technical problems to be solved in the utility model, be exactly for the existing deficiency of prior art, and provide a kind of semitrailer towing plate jacking system, this device can adjust easily the height of towing plate, make loading platform height adapt to tunnel or other special road conditions.
This programme is achieved by the following technical measures: a kind of semitrailer towing plate jacking system, it comprises towing plate, loading platform, adapter plate, guidepost and sleeper, described towing plate is fixedly connected with loading platform, on described towing plate, be provided with the pilot hole coordinating with guidepost, described guidepost is arranged on adapter plate, described adapter plate is fixedly connected with the traction seat of tractor truck, and described sleeper is arranged between towing plate and adapter plate.
Above-mentioned guidepost is provided with four.
Above-mentioned adapter plate is rectangle structure, and described four guideposts are distributed in four edges of adapter plate.
Above-mentioned guidepost and pilot hole are free-running fit.
The height of above-mentioned sleeper is 20～30cm.
The beneficial effect of this programme can be learnt according to the narration to such scheme, on adapter plate, be provided with four axis of guides, towing plate can be along axis of guide up-and-down movement, when superimposed trailer normally travels, between adapter plate and towing plate, be provided with sleeper, sleeper can support towing plate, the axis of guide positions towing plate, in the time that trailer needs process of passing through tunnel or other special road conditions, sleeper can unloaded, make the height of the towing plate 20～30cm that declines, the height of the loading platform 20～30cm that also declines.Compare towing plate is welded on the traction seat of tractor truck, the height of towing plate of the present utility model can regulate to adapt to the special road conditions such as tunnel.
As can be seen here, the utility model compared with prior art, has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model;
Fig. 2 is the structural representation of looking up of the present utility model.
1-loading platform in figure, 2-towing plate, 3-guidepost, 4-adapter plate, 5-sleeper, 6-longeron.
The specific embodiment
For clearly demonstrating the technical characterstic of this programme, below by the specific embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
As shown in the figure, a kind of semitrailer towing plate jacking system, it comprises loading platform 1, towing plate 2, guidepost 3, adapter plate 4 and sleeper 5, described towing plate 2 is fixedly connected with loading platform 1, on described towing plate 2, be provided with the pilot hole coordinating with guidepost 3, described guidepost 3 is arranged on adapter plate 4, and described adapter plate 4 is fixedly connected with the traction seat of tractor truck, and described sleeper 5 is arranged between towing plate 2 and adapter plate 4.
Above-mentioned guidepost 3 is provided with four, and four guideposts 3 position towing plate 2.
Above-mentioned adapter plate 4 is rectangle structure, and described four guideposts 3 are distributed in four edges of adapter plate 4.
Above-mentioned guidepost 3 is free-running fit with pilot hole.
The height of above-mentioned sleeper 5 is 20～30cm.Sleeper 5 is unloaded to the height of the towing plate 2 20～30cm that can decline.In the present embodiment, the height of sleeper 5 is 25cm.
When the superimposed trailer of transporting cargo travels in normal section, sleeper 5 is placed between towing plate 2 and adapter plate 4, make to keep between loading platform 1 and ground enough distances, in the time that superimposed trailer transportation overheight cargo is crossed tunnel or other special road conditions, can not pass through tunnel because the goods on loading platform 1 is too high time, below longeron 6, place jack, jack is by loading platform 1 jack-up, towing plate 2 also rises thereupon, sleeper 5 is extracted out, towing plate 2 is along with guidepost 3 decline 25cm, and loading platform 1 also declines thereupon, makes the height of loading platform 1 can pass through tunnel.When superimposed trailer is by behind tunnel,, by loading platform 1 jack-up sleeper 5 is placed between towing plate 2 and adapter plate 4 with jack, recover the height between loading platform 1 and ground.
In the utility model, can pass through or adopt existing techniques in realizing without the technical characterictic of describing; do not repeat them here; certainly; above-mentioned explanation is not to restriction of the present utility model; the utility model is also not limited in above-mentioned embodiment; variation, remodeling, interpolation or replacement that those of ordinary skill in the art makes in essential scope of the present utility model, also should belong to protection domain of the present utility model.
