Description

Portable dismounting device of bank bridge hoist tapered end hydro-cylinder

Technical Field

The utility model belongs to the technical field of lock cylinder disassembly, and particularly relates to a portable disassembling device for a lock cylinder of a shore bridge lifting appliance.

Background

The mawan intelligent harbor is the first to nationwide leading intelligent harbor in the major bay area of hong Kong, Guangdong, and has 20 shore bridges, and 36 lifting appliances are provided for the purpose. The complete and faultless lifting appliance is the basis for carrying out the boxing operation on the shore bridge, and if the lifting appliance is faulted, the operation of the shore bridge is limited, thereby causing unnecessary loss to a company. Therefore, the failure rate of the lifting appliance needs to be reduced so as to ensure stable and efficient production. Strengthening the maintenance and repair of the spreader is an important means to reduce the failure rate of the spreader and reduce the safety accidents of the spreader.

Among various faults of the lifting appliance, oil leakage of the lock cylinder is a very common fault, incomplete statistics is provided, and the fault accounts for 34.6% of all faults of the lifting appliance. Therefore, the workload of the working personnel for replacing the lock head is large every year, and the working frequency is high, so that how to finish the work more efficiently and more quickly becomes an important target. However, when the BROMMA lifting appliance is in work, due to the special design of the newly introduced BROMMA lifting appliance, when a traditional tool is used for disassembling the lock cylinder, the working process of disassembling work every time is extremely slow, the efficiency is low, and even the work can not be completed sometimes. Therefore, in order to solve the problem of disassembling the oil cylinder and respond to the innovative idea of the company, the company decides what the company can do.

In the traditional lock cylinder disassembling operation process, the friction force between the cylinder bearing of the old lifting appliance and the cylinder fixing column is very small, so that the old lifting appliance can be easily disassembled. However, due to the special design of the BROMMA lifting appliance, the friction force between the oil cylinder bearing and the oil cylinder fixing column is very large, and the BROMMA lifting appliance cannot be easily disassembled by using a traditional method. The tool such as a puller cannot be used due to the limited space, and the tool can only be detached by a crowbar or a hammer, but the left and right stress of the oil cylinder is not uniform during detaching, so that the end part of the oil cylinder is high or low at the left and right or high or low at the right. Secondly traditional instrument (like the crowbar) belongs to the single-point contact with the hydro-cylinder when dismantling, and the hydro-cylinder atress is also uneven this moment, causes the damage to hydro-cylinder bearing and hydro-cylinder fixed column very easily, further causes the damage to the hoist. And is very labor intensive and sometimes difficult to remove by even a few people for an extended period of time. In order to cope with this phenomenon, we think of making a special tool for this purpose, which is used to improve efficiency, save manpower, save time, and reduce cost.
