Description

Lifting locking device Technical Field The utility model relates to the technical field of lifting locking, in particular to a lifting locking device. Background In the bucket packaging process, the bucket is often required to be lifted to a specific height so as to carry out packaging operation, however, the existing bucket lifting device has a plurality of problems; 1. At the storage bucket location link, traditional mode is difficult to realize accurate central location, leads to the storage bucket to lift up with encapsulation in-process position offset easily, influences encapsulation quality and efficiency, and lacks effectual inclination prevention measure, and the storage bucket easily takes place to rock or incline in the transportation, has further increased the location degree of difficulty. 2. Stability after the storage bucket lifts up is difficult to ensure, and current lifting device lacks reliable locking mechanical system after lifting the storage bucket, and when the condition such as pressure release appears in the actuating cylinder, the storage bucket very easily descends, influences the normal clear of encapsulation process, probably causes the incident even. 3.
