Abstract
The utility model relates to a device for a pin on a boom of a caterpillar crane, particularly a self assembling and disassembling device for the pin on the boom of the caterpillar crane. The utility model has the technical proposal that an oil cylinder which is connected with the pin via a connecting pin is fixed on an oil cylinder fixing device by bolts, and the oil cylinder fixing device is fixed on a turntable by bolts. When the pin is assembled, a hydraulic valve is operated to make the oil cylinder extend out, then the pin is driven by the oil cylinder to move to the displacement position of the pin, the pin is positioned with the turntable by inserting a positioning pin, thereby, the assembly of the pin is accomplished, and the turntable is connected with the boom; when the pin is disassembled, the positioning pin is pulled out first, then the hydraulic valve is operated to make the oil cylinder retract, the pin is driven by the oil cylinder to move backwards to the original position of the pin, thereby, the disassembly of the pin is accomplished, and the boom is separated from the turntable. The utility model has the advantages of simple structure, reliable working, easy operation, high safety, no external force requirement, labor saving and high work efficiency.
Description
Affiliated technical field
The utility model relates to a kind of device of crawler crane boom hinge-point bearing pin, especially a kind of crawler crane boom bearing pin self-disassembly and assembly device.
Background technology
At present, need pull down arm during the crawler crane transition, and present crawler crane boom there is not self-disassembly and assembly device with the bearing pin that is connected of turntable, by manual work, effort, time-consuming, operating difficulties, also dangerous, efficient is also low.
Summary of the invention
For overcome present crawler crane boom be connected with turntable bearing pin from dismounting by manually-operated shortcoming, the utility model provides a kind of crawler crane boom bearing pin self-disassembly and assembly device, this device utilizes the hydraulic efficiency pressure system of hoisting crane self, additional device need be do not increased, the automatic dismounting of arm bearing pin can be realized.
The technical scheme that its technical matters that solves the utility model adopts is: oil cylinder (2) is connected with bearing pin (5) by connecting pin (4), be fixed on the oil-cylinder fixer (10) by bolt (3), oil-cylinder fixer (10) is fixed on the turntable (9) by bolt (7).When bearing pin (5) was installed, operation hydraulic valve (1) stretched out oil cylinder (2), drove bearing pin (5) motion, reached displacement bearing pin (5-1) position, made bearing pin (5) and turntable (9) location, promptly finished the installation of bearing pin (5), and turntable (9) is connected with arm (8); During dismounting bearing pin (5), extract locating dowel pin (6), operation hydraulic valve (1) earlier, make oil cylinder (2) retraction, drive bearing pin (5) toward swivel motion, reach the position of bearing pin (5), promptly finish the dismounting of bearing pin (5), arm (8) promptly separates with turntable (9).
The beneficial effects of the utility model are: this apparatus structure is simple and safe reliable, reliable operation, and easy operating does not need by external force, saves manpower, has improved work efficiency.
