Abstract
A kind of ultralow heavy tonnage lorry-mounted crane of the utility model, belongs to lorry-mounted crane or car hosit technical field; 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; The technical scheme adopted is: tail end and the column top be fixedly mounted on pivoting support of arm are hinged, arm is the hollow structure of cross-sectional plane rectangle, arm uncovered and other end bottom surface is closed near the bottom surface, one end of column, the cylinder body bottom of amplitude oil cylinder is hinged on the bottom sides of column and its piston rod end is uncovered from the bottom of arm stretches into inside and hinged with the middle part of arm, and it is inner near one end of column that hydraulic wireline winch is arranged on arm; The hinge-point of amplitude oil cylinder piston rod end and arm is arranged on arm inside by the utility model, hydraulic wireline winch is also arranged on arm inside, and complete machine height by amplitude oil cylinder and hydraulic wireline winch dimensional restriction, can not be designed into minimum, and owing to saving portion of material, reduce the weight of complete machine.
Description
Technical field
A kind of ultralow heavy tonnage lorry-mounted crane of the utility model, belongs to lorry-mounted crane or car hosit technical field.
Background technology
The lorry-mounted crane be equipped with for special vehicle requires that complete machine height is low, lightweight; Prior art adopts amplitude oil cylinder preposition and below that is hinged and arm, hydraulic wireline winch is arranged in below arm, as shown in Figure 3, this arrangement make complete machine height rearmounted compared with amplitude oil cylinder is reduced, but limit 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 reduce further.
Utility model content
The utility model 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 scheme that the utility model adopts is: a kind of 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 is arranged on bottom it 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 its piston rod end is hinged on the middle part of arm, described arm is the hollow structure of cross-sectional plane rectangle, arm uncovered and other end bottom surface is closed 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 uncovered from the bottom of arm stretches into inside and hinged with the middle part of arm.
Described arm inside is installed with the horizontal brace panel of L shape, and a side plate of described horizontal brace panel is parallel with the bus of amplitude oil cylinder during arm retracted state.
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 utility model is compared with the existing technology had is: the hinge-point of amplitude oil cylinder piston rod end and arm is arranged on arm inside by the utility model, and arm is uncovered bottom column one end, amplitude oil cylinder part is built in arm also for its activity leaves space, hydraulic wireline winch is also arranged on arm inside, complete machine height is not by amplitude oil cylinder and hydraulic wireline winch dimensional restriction, can be designed into minimum, and owing to saving portion of material, reduce the weight of complete machine; Horizontal brace panel and side brace panel achieve the local strengthening of arm.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the scheme of installation of horizontal brace panel and side brace panel in the utility model.
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 pinned connection hole.
Detailed description of the invention
As Fig. 1, shown in Fig. 2, a kind of ultralow heavy tonnage lorry-mounted crane of the utility model, 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 is arranged on bottom it on vehicle frame 1, the tail end of arm 4 and the top of column 3 are hinged, the cylinder body bottom of amplitude oil cylinder 3 is hinged on the bottom sides of column 3 and its piston rod end is hinged on the middle part of arm 4, described arm 4 is the hollow structure of cross-sectional plane rectangle, arm 4 uncovered and other end bottom surface is closed 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 uncovered from the bottom of arm 4 stretches into inside and hinged with the middle part of arm 4.
Described arm 4 inside is installed with the horizontal brace panel 7 of L shape, and a side plate of described horizontal brace panel 7 is parallel with the bus of amplitude oil cylinder 5 during arm 4 retracted state.
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-point.
The bottom panel of described arm 4 and two sides are welded and fixed and weld seam is positioned at arm 4 inside.
When structure allows, the installation site of hydraulic wireline winch 6 is as far as possible near the connecting shaft hole 9 of arm 4 with column 3, and away from the pinned connection hole 10 of amplitude oil cylinder 5, is arranged in by the less position of moment of flexure by hydraulic wireline winch 6; Arm 4 pinned connection hole 10 place of amplitude oil cylinder 5 and near suffered moment of flexure comparatively large, tackle it and carry out local strengthening, therefore horizontal brace panel 7 and side brace panel 8 are arranged for realizing local strengthening.
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, strengthens the hinged place of amplitude oil cylinder 5 and arm 4.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken that those of ordinary skill in the art possess, various change can also be made under the prerequisite not departing from the utility model aim.
