[0002] Port loading and unloading refers to various loading and unloading operations carried out at the port, including loading and unloading of ships at the front of the wharf, handling operations between the front and the rear, stacking and destacking operations in the port warehouse, and sorting and tallying operations. When loading and unloading, a measuring crane scale is needed for weighing. When installing the measuring crane scale, a changing device is needed to install the measuring crane scale on the hook of the crane.

[0003] Through research and analysis, it is found that although the existing replacement device can be used to install the metering crane scale, it still has the following disadvantages to a certain extent.

[0004] For example, because it does not have the function of adjusting the installation position during use, it is not convenient to adjust the metering crane scale to a suitable hanging position during replacement, which affects the installation speed of the metering crane scale. In addition, it does not have the function of clamping the metering crane scale, so when the metering crane scale is hung on the hook of the crane, the metering crane scale is prone to shaking, which makes it inconvenient to hang and install the metering crane scale. In order to solve the above technical problems, we have designed a rapid replacement device for port loading and unloading metering crane scales. Utility Model Content
