Welding tooling and welding method for driving frame of construction elevator

Abstract

The invention relates to the technical field of construction hoists, in particular to a welding fixture of a hoist driving frame and a welding method thereof. The welding fixture of the hoist driving frame and the welding method thereof eliminate or reduce welding deformation through predeformation, firstly weld welding lines of a main slot steel, a main connecting plate and a rectangle tube after changing a welding order simultaneously and and deform firstly, and then other parts are welded, thereby reducing the influence to the sizes of other parts which need to accurately determine because welding stress and deformation of the welding lines. Simultaneously, the welding fixture of the hoist driving frame and the welding method thereof carry out compression and positioning by utilizing a rapid fixture, improve work efficiency and labor strength, and can more conveniently and rapidly dismount workpieces by using a bearing.

Description

technical field [0001] The invention relates to the technical field of construction elevators, in particular to a welding tool for a driving frame of an elevator and a welding method thereof. Background technique [0002] The construction elevator is a manned and cargo-carrying construction machine often used in construction. It mainly plays the role of transporting construction workers and building materials to high altitude. It is mainly composed of guide rail frame, cage and driving device. The vertical movement of the construction elevator It is mainly realized through the cooperation of the motor drive gear and the rack. The motor with the drive gear is fixed on a special drive plate through bolts. The drive plate is connected to the special drive frame through bolts. The drive frame also includes a The lug plates connected to the cage, and the brackets and other structures used to install the rollers rolling on the guide rail frame, such as Figure 9 shown. The manufa...

Problems solved by technology

In this method, due to the thermal deformation of the welding process and the asymmetry of the structure, after the welding is completed and cooled, the distance between the two main channel steels of the main support frame away from the side of the main connecting plate and the rectangular tube becomes smaller, which cannot guarantee the The parallelism of the side main channel steel, and further, the dimensions of the components positioned on the cold-formed channel steel will also change accordingly, and the accuracy requirements of the entire product cannot be met, and the dimensions of the connected positioning parts cannot be guaranteed even after welding.
