The ultralow heavy tonnage lorry-mounted crane of the present invention, belongs to lorry-mounted crane or autocrane technical field; It is low that technical problem to be solved is to provide a kind of complete machine height, lightweight ultralow heavy tonnage lorry-mounted crane; The technical scheme adopting is: the tail end of arm is hinged with the column top being fixedly mounted on pivoting support, arm is the hollow-core construction of cross section rectangle, arm is uncovered and other end bottom surface sealing 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 uncovered inside hinged with the middle part of arm of stretching into, bottom from arm, and hydraulic wireline winch is arranged on one end inside of arm near column; The pin joint of amplitude oil cylinder piston rod end and arm is arranged on arm inside by the present invention, hydraulic wireline winch is also arranged on arm inside, and complete machine height is not subject to amplitude oil cylinder and hydraulic wireline winch size restrictions, can be designed into minimum, and owing to having saved part material, reduce the weight of complete machine.
Description
Technical field
The ultralow heavy tonnage lorry-mounted crane of the present invention, belongs to lorry-mounted crane or autocrane 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 physical dimension, 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 problem 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 its piston rod end and is hinged on the middle part of arm, described arm is the hollow-core construction of cross section rectangle, arm is uncovered and other end bottom surface sealing near the bottom surface, one end of column, hydraulic wireline winch is arranged on one end inside of arm near column, 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 stiffener, and a side plate of described horizontal stiffener 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 pin joint is all installed with a side stiffener.
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 pin joint of amplitude oil cylinder piston rod end and arm is arranged on arm inside by the present invention, and arm is uncovered near bottom, column one end, amplitude oil cylinder part is 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 size restrictions, can be designed into minimumly, and owing to having saved part material, reduce the weight of complete machine; Laterally stiffener and side stiffener have been realized the part reinforcement of arm.
Brief description of the drawings
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 stiffener and side stiffener 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 stiffener, and 8 is side stiffener, and 9 is connecting shaft hole, and 10 is bearing pin connecting hole.
Detailed description of the invention
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 its piston rod end and is hinged on the middle part of arm 4, described arm 4 is the hollow-core construction of cross section rectangle, arm 4 is uncovered and other end bottom surface sealing near the bottom surface, one end of column 3, hydraulic wireline winch 6 is arranged on one end inside of arm 4 near column 3, 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 stiffener 7, and a side plate of described horizontal stiffener 7 during with arm 4 retracted state the bus of amplitude oil cylinder 5 parallel.
Described arm 4 is all installed with a side stiffener 8 with the relative inner face of amplitude oil cylinder 5 piston rod end pin joints.
The bottom panel of described arm 4 and two sides are welded and fixed and weld seam is positioned at arm 4 inside.
The as far as possible connecting shaft hole 9 with column 3 near arm 4 of the installation site of hydraulic wireline winch 6 in the situation that structure allows, and away from the bearing pin connecting hole 10 of amplitude oil cylinder 5, be arranged in the position that is subject to moment of flexure less by hydraulic wireline winch 6; Arm 4 bearing pin connecting hole 10 places of amplitude oil cylinder 5 and near suffered moment of flexure larger, tackle it and carry out part and strengthen, therefore laterally stiffener 7 and side stiffener 8 arrange for realizing local reinforcement.
As shown in Figure 2, under the full reduced state of amplitude oil cylinder 5, transversary stiffener 7 is parallel to the busbar arrangement of amplitude oil cylinder 5, and side stiffener 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 skill in the art, can also under the prerequisite that does not depart from aim of the present invention, makes various variations.
