Description

Technical Field

[0001] The invention relates to a mechanical equipment disassembly and assembly maintenance technology, and more specifically to a hinge shaft quick disassembly and assembly maintenance device and a method thereof. Background Art

[0002] During the normal handling and placement of the front beam of the quay crane, the hinge point often makes abnormal noises. The main reason is often improper operation of the hinge shaft during installation, or untimely maintenance after use, which causes excessive wear of the internal bearing of the hinge seat and the hinge shaft, leading to necrosis of the hinge shaft and bearing. The traditional maintenance method is to use external force to forcibly knock the hinge shaft to disassemble and assemble. This not only requires a lot of manpower and low operating efficiency, but also the quality of disassembly and assembly cannot be effectively guaranteed. At the same time, the safety risk during the disassembly and assembly process is relatively high, which brings a certain degree of trouble to on-site maintenance work. Summary of the invention

[0017] Preferably, the connecting component is connected to the hinge shaft via a fixing bolt.

[0018] Preferably, the fixing component is provided with the other end of the connecting component connected to the hinge seat via a fixing bolt.

[0019] On the other hand, a hinge shaft quick disassembly and assembly maintenance method adopts the hinge shaft quick disassembly and assembly maintenance device, which is connected to the hinge seat to perform the disassembly or installation operation of the hinge shaft.

[0020] Preferably, the hinge shaft quick disassembly and maintenance method specifically includes the following steps:

[0021] 1) Place the front beam in a horizontal position;

[0022] 2) Remove the protective end cover of the hinge shaft on the front beam and the steel sleeve fixing bolts of the hinge seat;

[0023] 3) Connecting the connecting component to the end of the hinge shaft;

[0024] 4) Connecting the fixing component to the steel sleeve of the hinge seat;

[0025] 5) Install the driving component on the end of the fixing component, and then connect the connection limiting component to the driving component and the fixing component respectively;

[0026] 6) The hydraulic pressure provided by the driving component applies static pressure or reaction force to the hinge shaft to complete the disassembly or installation operation of the hinge shaft.

[0027] Preferably, in step 6), the hinge shaft is disassembled by installing the driving component on the inner side surface of the end of the fixing component and starting the driving component, so that the connecting component exerts static pressure on the hinge shaft to detach from the hinge seat through the pressure provided by the connecting limiting component;
