The folding hydraulic climbing ladder for the semitrailer is provided with the climbing ladder anti-collision blocks, so that collision between the front-section climbing ladder assembly and the rear-section climbing ladder assembly during transportation can be effectively prevented; the folding hydraulic climbing ladder for the semitrailer is simple in structure, reasonable in design, and safe and reliable in transportation.
Description
Technical field
The present invention relates to superimposed trailer technical field, particularly relate to a kind of superimposed trailer folding type hydraulic cat ladder.
Background technology
Existing superimposed trailer hydraulic climbing ladder can not fold usually, and easily breaks in transportation, and the rising of cat ladder and landing are not easy to operate, and needs to improve.
Summary of the invention
The object of the invention is exactly the defect in order to make up prior art, provides a kind of superimposed trailer folding type hydraulic cat ladder.
The present invention is achieved by the following technical solutions:
A kind of superimposed trailer folding type hydraulic cat ladder, include leading portion cat ladder assembly, back segment cat ladder assembly and tailgate assembly, at the upper and lower side left and right sides of leading portion cat ladder assembly, the left and right sides of the lower end of back segment cat ladder assembly and the upper end left and right sides of tailgate assembly are all welded with two fixing gussets, the centre hole alignment of the fixing gusset of the fixing gusset of the upper end of leading portion cat ladder assembly and the lower end of back segment cat ladder assembly, and in centre hole, insert bearing pin one, the centre hole alignment of the fixing gusset of the fixing gusset of the lower end of leading portion cat ladder assembly and the upper end of tailgate assembly, and in centre hole, insert bearing pin two, bearing pin one is also provided with cat ladder supporting leg, cat ladder supporting leg is positioned at the middle part of bearing pin one, described leading portion cat ladder assembly is welded with multiple cat ladder anticollison block, leading portion cat ladder assembly is provided with column oil cylinder.
Described bearing pin one and one end of bearing pin two are with boss, and the other end has pin-and-hole, and fixes with set pin.
Described cat ladder supporting leg includes base plate and 8 pieces of gussets, and the thickness of base plate is 5mm, is back-to-backly welded on base plate, gusset has every for 8 pieces of gussets two pieces perforation, is inserted on bearing pin one by gusset by perforation.
Described cat ladder anticollison block includes crash-proof bracket, briquetting and anti-collision rubber block, described crash-proof bracket is welded on leading portion cat ladder assembly, described anti-collision rubber block is notch cuttype, through hole is had in the middle of briquetting, briquetting is enclosed within the outside of anti-collision rubber block by through hole, briquetting and crash-proof bracket have multiple corresponding bolt mounting holes, by M9 bolt, briquetting and anti-collision rubber block is fixed on crash-proof bracket.
Hydraulic ram controls rising and the landing of overall cat ladder;
Back segment cat ladder assembly relies on self gravitation to decline in descent, along with cylinder movement is to final position in the process of hoisting, then pins with bearing pin, places and rock in transit;
Cat ladder supporting leg is in loading process, and play the effect supporting cat ladder, left, center, right is totally three supporting legs;
Cat ladder anticollison block is in overloading, and protect cat ladder, prevent cat ladder from damaging, arrange 6 anticollison blocks altogether, be steel plate structure bottom anticollison block, end is quality of rubber materials, is conducive to buffering;
Cat ladder entirety is divided into three, left, center, right part, and each part has independent oil cylinder, three Partial synchronization motions.
Advantage of the present invention is: the present invention is provided with cat ladder anticollison block, and when effectively can prevent transport, leading portion cat ladder assembly clashes into back segment cat ladder assembly, and structure is simple, and reasonable in design, transportation safety is reliable.
