Description

Technical Field

[0001] The utility model relates to the technical field of engineering machinery, in particular to a copper sleeve press-fitting machine. Background Art

[0002] In the construction machinery industry, copper sleeves are widely used as they can effectively withstand and bear the pressure generated by the installed components and the friction generated by the relative movement between the components. For crawler cranes, with the vigorous development of clean energy construction such as wind power and nuclear power in China, crawler cranes have also developed from the hundred-ton level to the thousand-ton level. Copper sleeves are used as installation transition pieces for key parts such as turntables and booms, pulley blocks, etc., and their importance is more prominent. Installation quality and efficiency have also become particularly important.

[0003] The existing technology is mainly installed in the following ways:

[0004] The first method is to install the copper sleeve by hammering it with a sledgehammer. This method is time-consuming and labor-intensive. This method has the following disadvantages: (1) It is time-consuming and labor-intensive; (2) There is a certain safety risk of working at height; (3) When installing the copper sleeve by hammering it with a sledgehammer, the hole is not easy to align. Local force is applied during hammering, which can easily cause the copper sleeve to deviate, affecting its installation quality.

[0005] The second method is to press the copper sleeve by a crawler-type hydraulic pump truck; however, it also has the following disadvantages: (1) The crawler-type hydraulic pump truck has a slow travel speed and cannot quickly switch work stations (assembly in the workshop, copper sleeve pressing of outdoor booms, copper sleeve pressing of turntables), resulting in a long ineffective waiting time, which affects the installation efficiency; (2) It is driven by fuel, and produces a lot of smoke and noise during operation, which is not suitable for indoor operations and causes great pollution to the environment; (3) Due to the interference of the copper sleeve pressing position, the oil cylinder needs to be switched. The existing technology uses a hydraulic hose connection method that is tightened by a joint, which has low switching efficiency and there is an oil leak that needs to be cleaned.
