Abstract
The utility model discloses a hydraulic lifting foldable ladder, which comprises a frame, wherein the tail end of the frame is hinged with a ladder; the ladder is formed by upper and lower sections of ladders in a hinging way; the tail end of the frame is hinged with a hydraulic cylinder; the end part of a hydraulic cylinder piston rod is hinged with the middle part of the lower section of ladder; a support rod is hinged between the rear end of the upper section of ladder and the tail end of the frame; and the front end of the upper section of ladder is provided with an idler wheel. The hydraulic lifting foldable ladder has simple structure, the original ladder structure is replaced by the ladder structure formed by upper and lower sections in a hinging way so as to prolong the length of the ladder, the ladder is lifted through the stretching of the hydraulic cylinder piston rod, the ladder is convenient to lift and the ladder has high practical value.
Description
Technical field
The utility model relates to the collapsible cat ladder of a kind of hydraulic lifting.
Background technology
The engineering low flat bed semi trailer is because of being announced limitation in height, from great, cat ladder length weak point, putting down relief angle spends greatly, when some engineering trucks of transportation, the loading difficulty is big, cat ladder lifting difficulty, therefore part engineering low flat bed semi trailer cat ladder can change that to make hydraulic lifting collapsible, both can avoid car load height and bulletin contradiction, can reach again increases cat ladder length, can also not be subjected to the lifting of cat ladder deadweight restraint of liberty.
The utility model content
The purpose of this utility model provides the collapsible cat ladder of a kind of hydraulic lifting, under the situation of not super bulletin height, increases cat ladder length, makes things convenient for the cat ladder lifting.
The technical solution of the utility model is as follows:
The collapsible cat ladder of a kind of hydraulic lifting includes vehicle frame, it is characterized in that: the tail end of described vehicle frame is hinged with cat ladder, and described cat ladder is by upper and lower joint cat ladder hinged composition; The tail end of described vehicle frame is hinged with hydraulic actuating cylinder, and the end of described hydraulic cylinder piston rod is hinged on the middle part of the described cat ladder of joint down, is hinged with strut between the rear end of described upward joint cat ladder and the tail end of described vehicle frame.
Described folding cat ladder is characterized in that: the described front end of going up the joint cat ladder is equipped with roller.
The beneficial effects of the utility model:
The utility model is simple in structure, and original cat ladder is modified into the cat ladder structure that two joints up and down are hinged, and has increased cat ladder length, simultaneously by hydraulic cylinder piston rod stretch the lifting cat ladder, made things convenient for the lifting of cat ladder, have good practical value.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
Referring to Fig. 1, the collapsible cat ladder of a kind of hydraulic lifting includes vehicle frame 1, and the tail end of vehicle frame 1 is hinged with cat ladder, and cat ladder is by 2,3 hinged compositions of upper and lower joint cat ladder; The tail end of vehicle frame 1 is hinged with hydraulic actuating cylinder 4, and the end of the piston rod 5 of hydraulic actuating cylinder 4 is hinged on down the middle part of joint cat ladder 3, on save between the tail end of the rear end of cat ladder 2 and vehicle frame 1 and be hinged with strut 6.
The front end of last joint cat ladder 2 is equipped with roller 7.
When not working, cat ladder is in the nature folded state, when cat ladder with oil cylinder contracted following time, on save cat ladder and stretch out forward because of the supporting role that is subjected to strut, and under the guiding of last joint cat ladder front end roller, make upper and lower cat ladder cat ladder be in linear state; Should install the load-carrying capacity that supporting seat guarantees cat ladder in the bottom of cat ladder additional simultaneously.
Claims (2)
