The invention discloses a disassembly and assembly device, a disassembly method and a mounting method for a crane and accessory structures thereof. The disassembly and assembly device of the accessory structures of the crane comprises a supporting structure, a second amplitude variation unit, a guide structure and a first winch, wherein the supporting structure comprises a first end and a second end; the first end is fixedly connected with the tail end of the main arm of the crane; the main arm of the crane is further connected with a first amplitude variation unit and used for changing the elevation angle of the main arm of the crane; the second amplitude variation is connected with the supporting structure and used for changing the angle of the supporting structure; the guide structure is arranged at the second end of the supporting structure; the first winch is arranged on the rotary table of the crane; the winding steel wire rope of the first winch penetrates through the guide structure and is used for lifting the accessory structures of the crane. According to the invention, the self disassembly and assembly of the accessory structures such as an auxiliary winch can be achieved without assistance of other cranes or hoisting tools, the disassembly and assembly device is convenient and efficient, and the cost is reduced.
Description
technical field [0001] The invention relates to the technical field of cranes, in particular to a disassembly device, a disassembly method and an installation method of a crane and its auxiliary structures. Background technique [0002] With the increase of the tonnage of the mobile crane, the corresponding weight of the whole vehicle also increases. Detachable form, that is, these auxiliary structures are only installed as needed when the crane is hoisting. [0003] For example, for the auxiliary hoist, most of them are mainly installed on the turntable or the counterweight frame, and are connected with the turntable through pins or bolts. When the work requires, because the auxiliary winch weighs more than 5 tons, it needs an auxiliary crane to hoist it to the installation position, and then connect it through the pin shaft. Therefore, every time the auxiliary winch is installed, an auxiliary crane must be followed, which is extremely inconvenient and greatly increases t...
