Connection method for upper top plate structure of lift

Abstract

The invention discloses a connection method for an upper top plate structure of a lift. The upper top plate is directly contacted with a load, the structure is welded by a plurality of mutually intersected perpendicular hot rolling channel steels in a welding manner, and auto sheets of 4000mmx2000mmx3mm are spread on the four side faces and the upper top face of each channel steel; four NO.16 hot rolling channel steels are arranged along the length direction of the upper top face of a platform, six NO.10 hot rolling channel steels are arranged along the width direction of the upper top face of the platform, and thus the upper top plate is formed; and a sliding groove for assembling an upper support and a lower support is processed on the foremost outer periphery along the length direction to facilitate the assembly of the upper support and the lower support. The connection method has the beneficial effects that the movement stability and correctness of execution parts are facilitated to be guaranteed, the manufacture precision is improved, the cost is lowered, meanwhile the improvement of operation controllability and energy-saving effect are facilitated.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a method for connecting an upper roof structure of an elevator. Background technique [0002] The hydraulic system has the advantages of large power, good adjustability of working pressure and flow, heat can be brought back to the oil tank, etc. The elevator is a kind of cargo lifting mechanism with good lifting performance and wide application range. It can be used for cargo transportation between equipment with height difference in the production line, material on-line and off-line, lifting of components during common assembly, and loading of large hangars. , blanking, warehousing and loading and unloading, and other places, it is used in conjunction with forklifts and other vehicles and fast loading and unloading of goods. It uses a hydraulic system device that can generate more power than other devices. Under the same power, the hydraulic device is small in size, light in ...

AI Technical Summary

Problems solved by technology

Of course, there are still many disadvantages in the hydraulic technology used for elevators. For example, the hydraulic pressure has more energy loss during the transmission process, and the hydraulic transmission is easy to leak. Motion stability and correctness; sensitive to oil temperature changes, high manufacturing precision requirements for hydraulic components, high cost, and difficult to find the cause of failure. Therefore, in practical applications, it is necessary to take effective measures to reduce disadvantages in all aspects one by one. factors, especially the upper roof structure
