Abstract
The invention discloses an ultralow large-tongue lorry-mounted crane and belongs to the technical field of lorry-mounted cranes or truck cranes. In order to solve the technical problem, the invention provides an ultralow large-tongue lorry-mounted crane which is low in overall height and light in weight. The technical scheme adopted by the invention is as follows: the tail end of a lifting arm is hinged with the top of a stand column which is fixedly mounted on a rotation bearing; the lifting arm is of a hollow structure with a rectangular cross section; the bottom surface of one end, close to the stand column, of the lifting arm is opened; the bottom surface of the other end of the lifting arm is closed; the bottom end of a cylinder body of an amplitude-variable oil cylinder is hinged with the side surface of the bottom of the stand column; the end part of a piston rod of the amplitude-variable oil cylinder extends from an opening of the bottom of the lifting arm to the interior of the lifting arm and is hinged with the middle of the lifting arm; a hydraulic winch is mounted in one end, close to the stand column, of the lifting arm. According to the ultralow large-tongue lorry-mounted crane, a hinged point of the end part of the piston rod of the amplitude-variable oil cylinder and the lifting arm is arranged in the lifting arm; the hydraulic winch is also arranged in the lifting arm; the overall height is not limited by the sizes of the amplitude-variable oil cylinder and the hydraulic winch and can be designed to the lowest; the overall weight is reduced as part of material is saved.
Description
Technical field
The ultralow heavy tonnage lorry-mounted crane of the present invention, belongs to lorry-mounted crane or car hosit technical field.
Background technology
The lorry-mounted crane being equipped with for special vehicle requires complete machine height low, lightweight; Prior art adopts the below of preposition and the hinged and arm of amplitude oil cylinder, hydraulic wireline winch is arranged in arm below, as shown in Figure 3, this arrangement is reduced complete machine height compared with amplitude oil cylinder postposition, but limited by amplitude oil cylinder and hydraulic wireline winch scantling of structure, be necessary for amplitude oil cylinder and hydraulic wireline winch leaves space, complete machine height can not further reduce.
Summary of the invention
The present invention overcomes the deficiency that prior art exists, and it is low that technical matters to be solved is to provide a kind of complete machine height, lightweight ultralow heavy tonnage lorry-mounted crane.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: ultralow heavy tonnage lorry-mounted crane, comprise vehicle frame, pivoting support, column, arm, amplitude oil cylinder and hydraulic wireline winch, the upper in-plane of pivoting support is installed with column and its bottom is arranged on vehicle frame, the tail end of arm and the top of column are hinged, the cylinder body bottom of amplitude oil cylinder is hinged on the bottom sides of column and the middle part that its piston rod end is hinged on arm, described arm is the hollow structure of cross-sectional plane rectangle, arm is uncovered and other end bottom surface sealing near the bottom surface, one end of column, it is inner near one end of column that hydraulic wireline winch is arranged on arm, the piston rod end of amplitude oil cylinder is from the uncovered inside hinged with the middle part of arm of stretching into, bottom of arm.
Described arm inside is installed with L shaped horizontal brace panel, and a side plate of described horizontal brace panel during with arm retracted state the bus of amplitude oil cylinder parallel.
The relative inner face of described arm and amplitude oil cylinder piston rod end hinge-point is all installed with a side brace panel.
The bottom panel of described arm and two sides are welded and fixed and weld seam is positioned at arm inside.
The beneficial effect that the present invention compared with the existing technology had is: the present invention is arranged on arm inside by the hinge-point of amplitude oil cylinder piston rod end and arm, and arm is uncovered near bottom, column one end, amplitude oil cylinder is partly built in to arm also for its activity leaves space, hydraulic wireline winch is also arranged on arm inside, complete machine height is not subject to amplitude oil cylinder and hydraulic wireline winch dimensional restriction, can be designed into minimumly, and owing to having saved part material, reduce the weight of complete machine; Laterally brace panel and side brace panel have been realized the part reinforcement of arm.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the invention will be further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is the horizontal scheme of installation of brace panel and side brace panel in the present invention.
Fig. 3 is the heavy tonnage lorry-mounted crane structural representation of prior art.
In figure: 1 is vehicle frame, 2 is pivoting support, and 3 is column, and 4 is arm, and 5 is amplitude oil cylinder, and 6 is hydraulic wireline winch, and 7 is horizontal brace panel, and 8 is side brace panel, and 9 is connecting shaft hole, and 10 is bearing pin connecting bore.
The specific embodiment
As Fig. 1, shown in Fig. 2, the ultralow heavy tonnage lorry-mounted crane of the present invention, comprise vehicle frame 1, pivoting support 2, column 3, arm 4, amplitude oil cylinder 5 and hydraulic wireline winch 6, the upper in-plane of pivoting support 2 is installed with column 3 and its bottom is arranged on vehicle frame 1, the top of the tail end of arm 4 and column 3 is hinged, the cylinder body bottom of amplitude oil cylinder 3 is hinged on the bottom sides of column 3 and the middle part that its piston rod end is hinged on arm 4, described arm 4 is the hollow structure of cross-sectional plane rectangle, arm 4 is uncovered and other end bottom surface sealing near the bottom surface, one end of column 3, it is inner near one end of column 3 that hydraulic wireline winch 6 is arranged on arm 4, the piston rod end of amplitude oil cylinder 3 is from the uncovered inside hinged with the middle part of arm 4 of stretching into, bottom of arm 4.
Described arm 4 inside are installed with L shaped horizontal brace panel 7, and a side plate of described horizontal brace panel 7 during with arm 4 retracted state the bus of amplitude oil cylinder 5 parallel.
Described arm 4 is all installed with a side brace panel 8 with the relative inner face of amplitude oil cylinder 5 piston rod end hinge-points.
The bottom panel of described arm 4 and two sides are welded and fixed and weld seam is positioned at arm 4 inside.
The installation site of hydraulic wireline winch 6 connecting shaft hole 9 with column 3 near arm 4 as far as possible in the situation that structure allows, and away from the bearing pin connecting bore 10 of amplitude oil cylinder 5, be about to hydraulic wireline winch 6 and be arranged in the position that is subject to moment of flexure less; Arm 4 bearing pin connecting bore 10 places of amplitude oil cylinder 5 and near suffered moment of flexure larger, tackle it and carry out part and strengthen, therefore laterally brace panel 7 and side brace panel 8 arrange for realizing local reinforcement.
As shown in Figure 2, under the full reduced state of amplitude oil cylinder 5, transversary brace panel 7 is parallel to the busbar arrangement of amplitude oil cylinder 5, and side brace panel 8 is welded in arm 4 two sides, and amplitude oil cylinder 5 and the hinged place of arm 4 are strengthened.
By reference to the accompanying drawings embodiments of the invention are explained in detail above, but the present invention is not limited to above-described embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from aim of the present invention, makes various variations.
