Description
Technical field
The utility model relates to a kind of trailer, a kind of gantry frame formula trailer of more specifically saying so.
Background technology
At present, in vast rural area and small towns, owing to be subjected to the restriction of conditions such as road conditions, agriculture truck, three wheeled motor car and trac. are main transportation meanss, these transportation meanss, great majority are the goods that betransported with the carrying of the hopper on the car, because hopper is higher apart from ground, at dress, when unloading goods, because of being subjected to the restriction in operation place can not adopt large-scale lifting machine again, can only lean on pushing away of manpower, draw, lift, original mode of operation such as shoulder, this original mode of operation not only will take great amount of manpower, material resources, time-consuming, operating efficiency is low, but also easily goes out accident on duty, and is dangerous.
Summary of the invention
The purpose of this utility model provides a kind of gantry frame formula trailer that is applicable to the loading and unloading of vast rural area and small towns, bearing goods.
In order to realize above-mentioned purpose, the gantry frame formula trailer that is provided, comprise the trailer body frame that has draw bar, on the trailer body frame suspension assembly is housed, on the suspension of suspension assembly wheel is housed, its constructional feature is to be connected with gantry frame on the trailer body frame, the lifting pulley group is equipped with on the top of gantry frame, the wirerope of capstan arrangement is walked around behind the pulley of lifting pulley group affixed with lift cart, the two ends of lift cart are provided with track adjusting wheel, track adjusting wheel is positioned at the guide groove of gantry frame two heel posts, is connected with hangers on the lift cart, and the hydraulic efficiency gear bonded assembly driving oil cylinder with trailer-type machine also is housed on the trailer body frame, driving oil cylinder is provided with by group, every group two, the installation site symmetry is connected with the revolution pressure pin on the piston rod of each driving oil cylinder, two revolution pressure pins of every group can laterally fasten, form the single-revolution carriage.
In order to improve load-carrying capacity, on the trailer body frame, also be connected to bearing frame, on gantry frame, be connected with reinforced plate.
Above-mentioned suspension assembly comprises two suspension positioning plates that are fixed on the bearing frame, be contained in two suspensions between the suspension positioning plate, be fixed on two guide fingers on the suspension, on every guide finger, be set with orienting sleeve, orienting sleeve is fixed on the bearing frame, between bearing frame and suspension spring is housed.
The group number of above-mentioned driving oil cylinder is two groups, is installed in the place, vertex angle part position of the rear and front end of trailer body frame respectively.
Gantry frame formula trailer described in the utility model is by trac. that capstan arrangement and hydraulic efficiency gear are housed or other the supporting use of tug tool.When will being placed on ground cargo compartment when on this trailer, loading, earlier cargo compartment is passed through suspension hook, chain sling, hawser or other attaching parts hang on the hangers, under the effect of capstan winch, driving lift cart by wirerope mentions cargo compartment, start driving oil cylinder, under the effect of piston rod, the revolution pressure pin rotates 90 ° of angles to the inboard of trailer body frame, promptly become laterally by vertical trend, the revolution pressure pin of two symmetries is buckled into the single-revolution carriage, so two groups of very strong goods brackets of load-bearing of horizontal formation in the rear and front end of trailer body frame, and then control capstan, by wirerope and lift cart cargo compartment is placed on the goods bracket, can carries out smooth transport.Opposite operation can be discharged at ground from trailer with cargo compartment.
Learn by above narration, gantry frame formula trailer provided by the utility model, with trac. that capstan arrangement and hydraulic efficiency gear are housed or other the supporting use of tug tool, not only can push away, draw, lift, shoulder the loading, unloading of finishing goods with what machinery substituted manpower, and do not need big operation place, be applicable to vast rural area and small towns.
