Abstract

The utility model discloses a link-type rear crawling ladder of a flat transport cart. The link-type crawling ladle of the flat transport cart comprises a cart body, wherein a supporting base is fixedly welded at the tail end of the cart body, a crawling ladder body is connected on the supporting base in a hinged mode, the crawling ladder body is composed of an upper section ladder and a lower section ladder in a hinged mode, a first link is hinged on the lower section ladder, a second link is hinged at the tail end of the cart body, and the end portion of the first link and the end portion of the second link are hinged mutually. The link-type rear crawling ladder of the flat transport cart is simple in structure. A traditional crawling ladder is divided into the upper section ladder and the lower section ladder which are mutually hinged, under the precise that the announced height is not surpassed, the length of the crawling ladder is increased effectively, the gradient of the crawling ladder is reduced, accordingly the purposes of the flat transport cart are more wide, and the good practical value is achieved.

Description

Cat ladder behind the link-type of flat bed transport vehicle
Technical field
The utility model relates to cat ladder behind a kind of link-type of flat bed transport vehicle.
Background technology
Flat bed transport vehicle be used for to load and transportation engineering machinery, digging machine, forklift, reaper etc., is applicable to the long-distance transport of construction machinery and equipment and some non-dismountable goods.
Market upper flat plate transport trolley is because being announced limitation in height now, cat ladder length is shorter, putting down relief angle spends greatly, when some engineering trucks of transportation, the loading difficulty is bigger, therefore is mainly used in the flat bed transport vehicle of transportation engineering vehicle such as roller class, cat ladder change make collapsible, both can avoid car load height and bulletin contradiction, can reach again increases cat ladder length, reduces the purpose of the cat ladder gradient.
The utility model content
The purpose of this utility model provides cat ladder behind a kind of link-type of flat bed transport vehicle, and cat ladder changes makes accordion structure, increases cat ladder length to reach, and reduces the purpose of the cat ladder gradient.
The technical solution of the utility model is as follows:
Cat ladder behind a kind of link-type of flat bed transport vehicle includes car body, and the tail end of described car body is fixedly welded with bearing, is hinged with cat ladder on the described bearing, and described cat ladder is by upper and lower joint terraced hinged composition; Be hinged with first connecting rod on the bed ladder, the tail end of car body is hinged with second connecting rod, and the end of first connecting rod and second connecting rod is hinged.
Cat ladder behind the link-type of described flat bed transport vehicle is characterized in that: the end at the described fly back side and the bottom at the bed ladder back side are fixedly welded with feet respectively.
The beneficial effects of the utility model:
The utility model is simple in structure, traditional cat ladder is divided into the upper and lower joint ladder that is hinged, under the prerequisite of not super bulletin height, effectively increased cat ladder length, reduce the cat ladder gradient, thereby made that the purposes of flat bed transport vehicle is more extensive, had good practical value.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, cat ladder behind a kind of link-type of flat bed transport vehicle includes car body 1, and the tail end of car body 1 is fixedly welded with bearing 2, is hinged with cat ladder on the bearing 2, and cat ladder is by 3,4 hinged compositions of upper and lower joint ladder; Be hinged with first connecting rod 5 on the bed ladder 4, the tail end of car body is hinged with second connecting rod 6, and first connecting rod 5 is hinged with the end of second connecting rod 6, is fixedly connected with hauling rope on the second connecting rod 6.
The bottom at the end at fly 3 back sides and bed ladder 4 back sides is fixedly welded with feet respectively, plays good supporting role when upper and lower joint ladder 3,4 is set level.
When central siphon outwards rotates, when spring became contraction state by extended state, upper and lower joint ladder 3,4 is become by folded state stretched level state, thereby formed one for engineering truck platform up and down; When central siphon inwardly rotates, when spring became extended state by contraction state, upper and lower joint ladder 3,4 reverted to folded state by stretching level state.
