Description
Technical field
The utility model relates to a kind of improvement of tractor trailer, specifically a kind of hydraulic loading-unloading tractor trailer.
Background technology
At aspects such as agricultural, water conservancy, capital construction, many cement prefabricated components and heavy integral article adopt tractor trailer to transport mostly.Used tractor trailer is made of trac. and trailer at present, by special-purpose crane heavy object is lifted on the tractor trailer from ground during use, or unloads down from tractor trailer.The weak point of this tractor trailer is: loading and unloading are inconvenient, loading and unloading are wasted time and energy, shipping and delivery cost is higher.What also have at present has adorned lifting appliance on trailer, comprise that suspension hook, arm, column, stay cord, motor constitute, and the seat end of arm is fixed on the lower end of column, the lifting appliance of this kind structure, undercapacity very heavy object is difficult to use, and operation is also convenient, flexible inadequately.
Summary of the invention
The purpose of this utility model be to provide a kind of not only simple in structure, can Self-loading ﹠ self-unloading, and intensity height, bearing capacity big, use convenient and swift, a kind of hydraulic loading-unloading tractor trailer flexibly of lifting.
For reaching above purpose, the technical scheme that the utility model adopted is: this hydraulic loading-unloading tractor trailer, by trac., trailer, column, arm and suspension hook constitute, the rear end of trac. is connected with trailer by bindiny mechanism, front end vertical fixing upper pillar stand at trailer, on it is characterized in that on rear side welding in the upper end of column is fixing, lower collar, last, insert Rotational Cylindrical in the lower collar, the upper end of Rotational Cylindrical is connected with the rear end of arm by turning cylinder, Rotational Cylindrical can be last, rotate in the lower collar, thereby realize the left side of arm, it is moving to turn right, hydraulic actuating cylinder permanent seat on the waist welding of Rotational Cylindrical is fixing, hydraulic actuating cylinder is fixed on the outer end of hydraulic actuating cylinder permanent seat by rotational pin, the end of hydraulically extensible bar is connected with the bottom side of arm by bearing pin, and hydraulic actuating cylinder is connected with tractor mounted hydraulic control pump by hydraulic pipe, by stretching of hydraulically extensible bar, make the arm lifting, establish suspension hook at the front end of arm.
The utility model is also implemented by following measure: at equidistant 3-5 bar diagonal ligament reinforced rib that is provided with of a week of column, to strengthen the support strength of column, the lower end of diagonal ligament reinforced rib is fixed on the vehicle frame of trailer; Establish vertical support bar and inclined support bar and digonal link at the upside of arm, as tower crane arm configuration shape, this structure can improve the load carrying ability of arm, on the front end upper wall of arm, be provided with the vertical bumping post of 6-10 root, the upper end collar of suspension hook is enclosed between two adjacent vertical bumping posts, can be according to the flexible mobile suspension hook of the distance position of lifting thing; The ring-type positioning baffle is also established in upper end in Rotational Cylindrical, glides to prevent Rotational Cylindrical.
When using the utility model,, arm is turned left and right along Rotational Cylindrical by artificial promotion arm, the primer fluid pressure device, the front end of arm can rise or descend, thus the drive suspension hook can rise or descend, thus sling or fall the load-carrying object.
The beneficial effects of the utility model are: compare with the tractor trailer that has lifting appliance at present, not only simple in structure, energy Self-loading ﹠ self-unloading, and lift by crane intensity height, flexible operation, time saving and energy saving, can improve field of application, reduce the goods transport cost, increase economic efficiency.
