Description

A device for uncovering the tarpaulin of the cargo stack and its application method

technical field

The invention relates to the technical field of uncovering and covering sheets of goods stacks, in particular to a device for uncovering and covering sheets of goods stacks and a method for using the same.

Background technique

Due to logistics control and site restrictions, bulk finished products (such as section steel, steel coils, wire rods, etc.) are mostly stored in outdoor pallets, and the palletizing method is mostly hanging by gantry cranes. Due to product quality control requirements, the stacks for storing finished products need to be covered with tarpaulins. The maximum size of the stacks is 12m wide and 4m high. According to statistics, the number of stacks exceeds 100 at the peak of production, and fluctuates in the range of 50-60 daily. Through research, the current port transshipment warehouses, enterprise transfer warehouses and finished product warehouses are all manual operations. The operation requires the cooperation of 4 people. Two people climb the ladder to pull the tarpaulin. The operation time of a single stack is about 20 minutes. After the sheet is uncovered, a larger space is needed to organize and store the sheet.

There are many disadvantages in the existing method: ①Because the existing operation method involves high-altitude operations (more than 2 meters above the ground), there is a safety risk of falling during operation; and profiles), it is easy to scratch the operator’s hands and the sheet during the cover removal process, which brings safety risks and reduces the quality of quality control; ③ Due to the large number of stacks, the manual operation method is intensive (about 1000 minutes per day), and the efficiency low. ④Before the cover of the tarpaulin, personnel are required to store and organize the tarpaulin after it is uncovered, which increases site requirements and work intensity.
