Description

Semitrailer hydraulic folding climbing ladder
Technical field
The utility model belongs to semitrailer technical field, and in particular to a kind of semitrailer hydraulic folding climbing ladder.
Background technology
Cat ladder is equipped with for the semi-trailer tail of conveying asphalt paver vehicle, since tar spraying car is longer, and ramp angle It is smaller, it is generally less than 12 degree, it is therefore desirable to which longer cat ladder, usual cat ladder length are more than 4 meters, it is therefore desirable to set dedicated climb Ladder.In the prior art, cat ladder uses spring lifting structure, and using manually overturning, and not foldable, troublesome in poeration, security Difference, manual operation increase labor intensity.
Utility model content
The purpose of this utility model is to provide a kind of semitrailer hydraulic folding climbing ladder, to solve the above problems.
The utility model semitrailer hydraulic folding climbing ladder, including cat ladder seat, cat ladder one and cat ladder two, cat ladder seat is fixed on half Trailer tail, cat ladder one are hinged with cat ladder seat, and cat ladder one is hinged with cat ladder two, and one bottom of cat ladder is equipped with landing oil cylinder, cat ladder one Folding ram is equipped with two bottom of cat ladder, the oil cylinder end of folding ram is fixed on one bottom of cat ladder, the tailpiece of the piston rod of folding ram It is fixed on two bottom of cat ladder.
Use principle:Under the action of landing oil cylinder, cat ladder one and cat ladder two are slowly unfolded, and cat ladder two is in the effect of gravity Under, certain angle is opened, then again under the action of folding ram, is stretched out completely, with cat ladder one into 180 degree angle;When packing up, Under the effect of gravity, cat ladder two is bent to cat ladder one, then under the action of landing oil cylinder, cat ladder one and cat ladder two after folding In overturning to cat ladder seat.
Cat ladder seat is equipped with alarm, and alarm is connected with the control unit of driver's cabin, and when cat ladder folding and unfolding sends alarm signal Number, operating personnel and vehicle-surroundings personnel is prompted to take care.
At least a pair of of support leg is equipped on cat ladder one and cat ladder two.
Compared with prior art, the utility model has the advantage of:The utility model semitrailer hydraulic folding climbing ladder, by original Come the spring lifting mechanism of cat ladder and manually overturn to fold to be changed to hydraulic control, reduce the labor intensity of operator, improve Efficiency, security performance higher set foldable structure, convenient for the folding storage of long cat ladder.
Description of the drawings
Fig. 1 is the structure diagram of the utility model semitrailer hydraulic folding climbing ladder;
Fig. 2 is the top view after the expansion of the utility model semitrailer hydraulic folding climbing ladder;
In figure:1st, cat ladder seat, 2, cat ladder one, 3, cat ladder two, 4, landing oil cylinder, 5, folding ram, 6, semi-trailer tail, 7, Support leg, 8, alarm.
Specific embodiment
Below against attached drawing, by the description to optimum embodiment, specific embodiment of the present utility model is made into one Step detailed description.
As illustrated in fig. 1 and 2, a kind of semitrailer hydraulic folding climbing ladder, including cat ladder seat 1, cat ladder 1 and cat ladder 23, cat ladder Seat 1 is fixed on semi-trailer tail 6, and cat ladder 1 is hinged with cat ladder seat 1, and cat ladder 1 is hinged with cat ladder 23, and one 2 bottom of cat ladder is set There is landing oil cylinder 4, cat ladder 1 and 23 bottom of cat ladder are equipped with folding ram 5, and the oil cylinder end of folding ram 5 is fixed on cat ladder 1 Bottom, the tailpiece of the piston rod of folding ram 5 are fixed on 23 bottom of cat ladder.
Cat ladder seat 1 is equipped with alarm 8, and alarm 8 is connected with the control unit of driver's cabin.
At least a pair of of support leg 7 is equipped on cat ladder 1 and cat ladder 23.
In conclusion the utility model semitrailer hydraulic folding climbing ladder, by the spring lifting mechanism of original cat ladder and manually Overturning folds and is changed to hydraulic control, reduces the labor intensity of operator, improves efficiency, and security performance higher is set Foldable structure, convenient for the folding storage of long cat ladder.
The above is that the utility model is exemplarily described, it is clear that the utility model implements and from above-mentioned side Any variation is whether done in the limitation of formula in its shape or structure, if employ the utility model methodology and The design of the utility model and technical solution not improved directly should by the improvement for the various unsubstantialities that technical solution carries out For other occasions, within the scope of protection of the utility model.
