Problems solved by technology
[0002] Cranes are the main loading and unloading machinery in the port. The number of machines is large and the utilization rate is relatively high. Therefore, the wear cycle of the luffing guide shaft is relatively short. Generally, it needs to be replaced every 2-3 years. However, the traditional disassembly process of the luffing guide shaft is very difficult. Large, high risk factor, in order to solve this problem, it is necessary to design and develop a special tool according to the structural characteristics of the machine to meet the safe operation requirements during the disassembly and assembly of the luffing guide shaft

Embodiment Construction
[0028] The special dismounting tool for the luffing guide shaft of the crane of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] as attached Figure 1-2 As shown, a special dismounting tool for the luffing guide shaft of a crane is composed of a first body 3 and a second body. It consists of a base 1 and a raised part 2, wherein the raised part is located on the lower surface of the base. In order to disassemble the luffing guide shaft of the 25-ton crane, the height of the first body is 300mm, and the outer diameter of the first body is the same as that of the base, both of which are 80mm. The inner diameter of the first body is compatible with the diameter of the raised part. The diameter of the raised part is 38mm, and the inner diameter of the first body is 40mm. When the second body covers the first body, the raised part can be positioned on the first body. in the inner hole of the body. Both the height of ...

The invention discloses a special disassembly and assembly tool for an amplitude-changing guide shaft of a crane and a use method thereof. The special disassembly and assembly tool is composed of a first body and a second body, the first body is a cylindrical cavity with the upper part opened, the second body is composed of a base and a protruding part arranged at the lower surface of the base, and the base and the protruding part are of coaxial cylindrical shapes, wherein the outer diameter of the first body is equal to the diameter of the base, the the diameter of the protruding part is matched with the inner diameter of the first body, and the second body can cover the first body. The special disassembly and assembly tool is small in mass and size and convenient to disassemble and assemble, and can replace the amplitude-changing guide shaft temporarily; when the second body of the special disassembly and assembly tool covers the first body, the special disassembly and assembly tool can serve as a prop; when the second body is separated from the first body, the first body can serve as a guide sleeve of the prop, and the conversion process is easy and convenient to operate.
Description
technical field [0001] The invention belongs to the field of dismantling a luffing guide shaft of a crane, and specifically relates to a special disassembly tool for a luffing guide shaft of a crane and a using method thereof. Background technique [0002] Cranes are the main loading and unloading machinery in the port. The number of machines is large and the utilization rate is relatively high. Therefore, the wear cycle of the luffing guide shaft is relatively short. Generally, it needs to be replaced every 2-3 years. However, the traditional disassembly process of the luffing guide shaft is very difficult. Large, high risk factor, in order to solve this problem, it is necessary to design and develop a special tool according to the structural characteristics of the machine to meet the safe operation requirements during the disassembly and assembly of the luffing guide shaft. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the object of the ...
