Description

Technical Field

[0001] The invention belongs to the technical field of large-scale mechanical equipment assembly, and relates to a large-scale cover linear adjustment auxiliary support device and a use method thereof. Background Art

[0002] During the assembly and debugging of large-scale mechanical equipment, the operator is not only required to accurately install the functional supporting finished products into the equipment cabin of the large-scale mechanical equipment according to the assembly technical requirements, but also to debug its related functions after the assembly work is completed. For this purpose, a S=0.01-1.5m 2 Various types of covers with different areas and numbers constitute the later ground debugging, maintenance and repair windows to meet the relevant debugging and maintenance needs. At present, for covers with smaller areas, operators only need to use process screws to assist in installing them on the skin structure of the covers of large mechanical equipment, but for covers with an area of ​​S = 1.5㎡, operators need to enter the equipment cabin to carry out relevant installation and debugging work, which requires opening the large cover and leaning on the surrounding structure or another operator to manually support it with their hands for a long time until the debugging of the work is completed. Although the above method can also well complete the relevant installation and debugging work of the equipment cabin, some problems are also reflected in the actual work: First, for covers with an area of ​​more than 1.5㎡, although they can be leaned on the surrounding structure of large-scale mechanical equipment with the help of single-sided folding, when the surrounding structure is assembled with the corresponding functional finished product, since the weight of the cover is more than 40Kg, there is a safety risk that the cover will damage the functional finished product, thereby causing unnecessary economic losses and increasing manufacturing costs; second, for large covers that cannot be directly leaned on the surrounding structure of large-scale mechanical equipment, another operator is required to manually assist in long-term support to complete the relevant debugging work, which not only causes a waste of manpower, but also long-term manual support will increase the fatigue intensity of the operator. Once the spirit is relaxed, the cover slips, which can easily cause a personal safety hazard to the operator; third, for large-area covers, due to the needs of operation and debugging, they need to be frequently opened and closed at different angles, which also increases the difficulty of operation and work intensity.
