Abstract
A hydraulic open-close device for a truck trunk door relates to an open-close device for a truck trunk door, and comprises a hydraulic oil tank, at least two lifting cylinders, an oil way and a truck trunk. The hydraulic oil tank is connected with an oil pump and connected with the lifting cylinders through the oil way, one of the hydraulic oil tanks is connected with the front end of the truck trunk, and the other hydraulic oil tank is connected with a trunk door which is connected with the upper ends of the left wall and the right wall of the truck trunk through pivots. A valve is connected between the hydraulic oil tank and the oil pump and between the lifting cylinder and the oil pump respectively. The hydraulic open-close device for a truck trunk door is simple in structure, convenient in installation, safe in opening, blockage-free, saving in cost, and suitable for all domestic or imported medium-large type engineering trucks, road vehicles and the like.
Description
Technical field
The utility model relates to a kind of opening and closing device of transport truck wagon backdoor.
Background technology
The cargo box door body of common transport truck bottom generally is and terminal pivotal joint at the bottom of the container case, the upper end is connected the sealing of carrying out container with the left and right sidewall of load compartment body, during unlatching, pine opening door body upper end is connected with left and right sidewall, behind the pivot Rotate 180 degree of door body bottom, can open chamber door, though it is convenient, simple, but when transportation stone or granular article, pivotal joint place at the bottom of the Men Tiyu container case is stopped up by stone or granular substance easily, thereby clamp the body door body, cause the switching of body door body limited.
Summary of the invention
The purpose of this utility model is intended to overcome the defective of prior art, provides that a kind of unlatching is convenient, safety, and can not cause the fluid pressure type automobile rear cabinet device for opening/closing door that stops up.
Fluid pressure type automobile rear cabinet device for opening/closing door described in the utility model, constitute by hydraulic oil fuel tank, elevating ram, oil circuit and railway carriage, the hydraulic oil fuel tank is connected with oil pump, and be connected with elevating ram by oil circuit, elevating ram is at least two, one is connected with the railway carriage front end, another is connected with the body door body, the body door body is connected by the upper end of pivot with railway carriage and arranged on left and right sides wall, is connected with valve between hydraulic oil fuel tank and the oil pump, is connected with valve between elevating ram and the oil pump.
Described oil pump is a single tube road binders pump.Described oil pump is the dual circuit oil pump.Be connected with limit valve on the described body door body, limit valve can be that the Mechanical Driven limit valve also can be automatically controlled limit valve.Described elevating ram is three, and one is connected with the box body front end, and other two elevating rams are connected with the left and right two ends of body door body respectively.
Fluid pressure type automobile rear cabinet device for opening/closing door described in the utility model, the hydraulic oil fuel tank is connected with elevating ram, under the effect of oil pump the hydraulic oil in the fuel tank is pumped, and flows to elevating ram through oil circuit, and elevating ram is risen under the effect of hydraulic fluid pressure.Be connected with one-way cock between hydraulic oil fuel tank and the oil circuit, when oil pump is the monomer oil pump, oil pump and valve are two covers, one cover is connected with the body door body, another set ofly be connected with the railway carriage front end, when valve open, hydraulic oil in the fuel tank flows out, and flow to elevating ram along oil circuit, under the effect of hydraulic pressure, realize the body door body open or the front end of railway carriage lifts, conveniently to topple over the article in the railway carriage, when the article in the railway carriage topple over finish after, valve-off, under the effect of gravity, hydraulic oil is recycled in the hydraulic oil fuel tank along oil circuit, the body door body is closed or the front end of railway carriage puts down, when oil pump is the monomer oil pump, can only realize a function in lifting container or the unlatching car door separately, different time uses.When oil pump was series connection binary oil pump, valve was two, opens one of them valve and can realize lifting and putting down of railway carriage front end, opened another and then can realize the unlatching of body door body or close that two valves can use simultaneously.
Fluid pressure type automobile rear cabinet device for opening/closing door described in the utility model, at the transportation boulder, during the granular article of big lump ore or its, article can truck doors, improve lifting railway carriage safety index, reduce the labour intensity of navigating mate, reducing the related personnel is opening, casualty accident takes place when closing behind the lorry chamber door, the utility model is when the lifting container, big block article can not form impact to the back door of lorry container, and the damage back door when opening and closing device described in the utility model is installed, does not have change to the cargo box structure that has lorry now, function does not change yet, and can also prolong container back door tenure of use.This practical new construction is simple, easy for installation, and cost saving is to now all are homemade, the big-and-middle-sized engineering truck of import, highway car etc. are all applicable.
