Description
Technical Field
The utility model belongs to the technical field of the hoist seat, concretely relates to roll over arm for mobile crane rotary seat mechanism.
Background
The folding arm automobile crane has strong lifting capacity and flexibility, is widely applied to the fields of logistics transportation, landscaping, civil engineering, fire fighting, electric power and the like, and is a novel high-efficiency multipurpose special device. The folding arm automobile crane has strong adaptability to the operation environment, can finish the hoisting and transferring of goods in a narrow space, is particularly suitable for the moving of large-scale equipment in a factory building, and is not possessed by the conventional automobile crane.
At present, the crane of the domestic arm-folding automobile just starts, and has a single structural style and is still imperfect. Like the seat structure, current seat structure all places and leans on the back position in revolving stage side, and it is great that operating personnel's sight is influenced by crane structure, has the field of vision blind area, can't realize the real time monitoring to crane hook position.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a roll over arm for mobile crane rotatory seat mechanism. The rotary seat mechanism is used for improving the visual field of an operator and improving the operation safety.
The utility model discloses a realize through following technical scheme: the utility model provides a roll over arm for mobile crane rotatory seat mechanism, includes the seat, and seat fixed mounting is on the link, and the link is connected with connecting rod I, and the other end and the mount pad swing joint of connecting rod I, the front end at the revolving stage structure is fixed to the mount pad, still swing joint has actuating cylinder between link and the mount pad.
Furthermore, a connecting rod II is movably hinged between the connecting frame and the mounting seat.
Furthermore, one end of the driving oil cylinder and the connecting rod I are hinged to the mounting seat through a pin shaft II, and the other end of the connecting rod I is hinged to the connecting frame through a pin shaft I; the other end of the driving oil cylinder and the connecting rod II are hinged to the connecting frame through a pin shaft IV, and the other end of the connecting rod II is hinged to the mounting seat through a pin shaft III.
Furthermore, a piston rod of the driving oil cylinder is hinged with the mounting seat, and a base of the driving oil cylinder is hinged with the connecting frame.
The utility model has the advantages that: the seat is positioned below the front end of the rotary table structure, and in an operation state, the visual field is good, no blind area exists, and the operation safety is ensured; in the rotation process of the seat, the direction is always unchanged, so that an operator can observe a lifting point area all the time, and the operation safety is improved; the seat position is low, makes things convenient for operating personnel to climb from top to bottom.
Drawings
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the seat retrieval and seat deployment of the present invention;
FIG. 3 is a schematic view of the installation of the present invention;
in the figure, the chair comprises a seat 1, a seat 2, pin shafts I and 3, connecting rods I and 4, a driving oil cylinder 5, pin shafts II and 6, a mounting seat 7, pin shafts III and 8, connecting rods II and 9, pin shafts IV and 10 and a connecting frame.
Detailed Description
The invention will be further explained below with reference to the drawings and examples.
As shown in fig. 1 to 3, a rotary seat mechanism for a folding arm automobile crane comprises a seat 1, wherein the seat 1 is fixedly installed on a connecting frame 10, the connecting frame 10 is connected with a connecting rod i 3, the other end of the connecting rod i 3 is movably connected with an installation seat 6, the installation seat 6 is fixed at the front end of a rotary table structure, and a driving oil cylinder 4 is movably connected between the connecting frame 10 and the installation seat 6. When the vehicle runs, the driving oil cylinder 4 is fully contracted, and the seat 1 is retracted into the width limit of the vehicle, so that the vehicle does not influence the running on the road. When the crane works, the driving oil cylinder 4 extends fully, the seat is rotated to the outer side and is far away from the crane arm support, the visual field of operators is improved, and the operation safety is improved.
Further, still activity hinge joint has connecting rod II 8 between link 10 and the mount pad 6, promotes link 10 to the support intensity of seat 1 to realize the flexible in-process of actuating cylinder 4, the direction of seat 1 is unchangeable all the time, thereby guarantees that operating personnel faces the arm head direction all the time, so that observe the hoisting point region.
Furthermore, one end of the driving oil cylinder 4 and the connecting rod I3 are hinged to the mounting seat 6 through a pin shaft II 5, and the other end of the connecting rod I3 is hinged to the connecting frame 10 through a pin shaft I2; the other end of the driving oil cylinder 4 and the connecting rod II 8 are hinged to the connecting frame 10 through a pin shaft IV 9, and the other end of the connecting rod II 8 is hinged to the mounting seat 6 through a pin shaft III 7. Furthermore, a piston rod of the driving oil cylinder 4 is hinged with the mounting seat 6, and a base of the driving oil cylinder 4 is hinged with the connecting frame 10.
The rotary seat can provide a better visual field for operators, is lower in position, can be far away from the arm body during operation, improves the operation safety, and can ensure that the rotary seat is not ultra-wide in the driving process.
