Lifting platform for machining
Technical Field
The invention relates to the technical field of machining, in particular to a lifting platform for machining.
Background
At present, the shear type lifting platform is mainly used for the mechanical processing industry, the transportation of goods and parts of a production line and the like, and has the characteristics of stable structure, low failure rate, reliable operation, safety, high efficiency, simplicity and convenience in maintenance and the like.
The existing scissor type lifting platform has certain disadvantages when in use, although the existing scissor type lifting platform can keep a horizontal state after being lowered, mechanical parts are easy to be clamped and fall in gaps on the side surface of the lifting platform when bumping or slope road sections are met, and lifting operation is affected when the existing scissor type lifting platform is lifted again, so that the mechanical parts are clamped in the gaps and are difficult to take out. Although the shielding object can be placed in the gap, the shielding object is easy to cause paint falling or damage around the lifting platform, and is not beneficial to use and operation.
Therefore, it is highly desirable to design a lifting table for machining, which can protect the machine parts in the gaps around the machine parts, and is not easy to be stuck or taken out.
