Description
Technical Field
The invention relates to a lifting platform, in particular to a lifting platform for transferring a slender revolving body product from a production line to a storage shelf or a transfer trolley on large-scale transportation equipment.
Background
After being formed on a processing production line, an elongated revolving body, such as an underwater vehicle shell, needs to be moved from the production line to a transfer trolley and transferred to a large-scale transport vehicle or a goods shelf by the transfer trolley for storage; in the prior art, the transportation of the slender revolving body is generally completed by two independent transport vehicles, and the process is as follows: firstly, two independent transfer vehicles are arranged beside a processing production line, a rack on the two transfer vehicles is operated to be lifted to the height of the processing production line of the slender revolving body, the slender revolving body which is processed and formed is translated to two transport vehicles to be fixed, then the two transfer vehicles are operated simultaneously to transfer the slender revolving body product to the transport vehicles or the side of a goods shelf, the rack on the two vehicles is operated simultaneously again to be lifted to the height of the goods shelf or the height of the transport vehicles, and the revolving body is translated to the goods shelf or the transport vehicles. Because the slender revolving body product has the characteristics of longer length and the center of gravity usually deviated from the central position, the accidents of center of gravity deviation and inclined turning of the transfer vehicle are easy to occur when the slender revolving body is carried by two transfer vehicles; when the racks on the two transfer vehicles are operated to lift, the problem that the racks are not lifted synchronously often exists, the long and thin products are easy to incline and damage, and the technical problem which needs to be solved on site is solved by how to solve the problem that the two support racks lift synchronously. The profile of some slender rotator shells is irregular, the bending rigidity is very poor, and how to conveniently and stably support the slender rotator shells on a transfer trolley is also a technical problem to be solved on site. In addition, the lifting platform operating mechanism of the existing transfer vehicle is arranged separately from the lifting platform, operators need to be configured on the vehicle and off the vehicle respectively during operation, manpower cost is wasted, how to realize that lifting operation and product transfer are completed simultaneously by the personnel on the vehicle is also a technical problem existing on site.
