Description
Technical field
The utility model relates to hoisting and hanging technical field, is specially a kind of suspension arm supporting device.
Background technology
In material handling field, rotary crane is wherein a kind of important handling machinery, it can complete the operations such as feeding, migration, unloading, in equipment of Vessel, rotary crane is main handling machinery, the arm of rotary crane completes the lifting carrying of material, generally all carry out lifting mobile, because the material ratio of lifting is heavier, arm needs to bear larger pressure, if need the conveying carrying out longer distance, corresponding length of boom also becomes longer, require to uprise to arm weight capacity, if lifting material is overweight, easily overturning phenomenon occurs.
Summary of the invention
In order to solve the problem, the utility model provides a kind of suspension arm supporting device, and its structure is simple, can realize the support of arm easily, alleviate the load-bearing pressure of arm.
Its technical scheme is such: a kind of suspension arm supporting device, it is characterized in that, it comprises supporting seat, described supporting seat upper end has groove, by bearing pin, rotating U-shaped stay bearing plate is installed in described groove, the piston rod of described U-shaped stay bearing plate one end bottom attachment support oil cylinder, the cylinder body afterbody of described support cylinder rotates and is installed on described supporting seat sidepiece.
It is further characterized in that, the bottom portion of groove fixed installation jacking cylinder of the described supporting seat of described U-shaped stay bearing plate lower end, the top board of installation activity on the piston rod of described jacking cylinder.
After adopting structure of the present utility model, suspension arm support is on U-shaped stay bearing plate, and the support cylinder of U-shaped stay bearing plate lower end drives U-shaped stay bearing plate and arm to fit tightly, and realize the support of arm easily, its structure is simple, alleviates the load-bearing pressure of arm.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model structure right elevation.
Detailed description of the invention
See Fig. 1, shown in Fig. 2, a kind of suspension arm supporting device, it comprises supporting seat 1, supporting seat 1 upper end has groove 2, install rotating U-shaped stay bearing plate 4 by bearing pin 3, the piston rod of U-shaped stay bearing plate 4 one end bottom attachment support oil cylinder 5 in groove 2, the cylinder body afterbody of support cylinder 5 rotates and is installed on supporting seat 1 sidepiece; Jacking cylinder 6 is fixedly mounted bottom the groove 2 of the supporting seat 1 of U-shaped stay bearing plate 4 lower end, the top board 7 of installation activity on the piston rod of jacking cylinder 6, because suspension arm support is on U-shaped stay bearing plate 4, U-shaped stay bearing plate 4 and bearing pin 3 bear larger pressure, arranging of jacking cylinder 6 can alleviate its pressure, when the piston rod of jacking cylinder 6 stretches out, when top board 7 is moved to U-shaped stay bearing plate 4, top board 7 automatically can contact with U-shaped stay bearing plate 4 and fit tightly, and U-shaped stay bearing plate 4 lower end is supported by jacking cylinder 6.
Claims (2)
