Welding tooling for the extended platform of the standard section of the lift

Abstract

The invention discloses a welding tool for an elevator standard knot expansion platform. The welding tool comprises a welding frame and a vertical frame body and a platform frame body which are fixed to the welding frame. The welding frame is of an integrated structure formed by welding a longitudinal limiting framework and a transverse limiting framework. A first pin shaft base with a pin hole is arranged at the upper end of the vertical frame body. A second pin shaft base with a pin hole is arranged at the lower end of the vertical frame body. A first pin shaft corresponding to the first pin shaft base and a second pin shaft corresponding to the second pin shaft base are welded to the welding frame. First threaded holes are symmetrically formed in the left portion and the right portion of the front end of the platform frame body. Second threaded holes are symmetrically formed in the left portion and the right portion of the rear end of the platform frame body. First bolts matched with the first threaded holes are arranged at the front end of the welding frame. Second bolts matched with the second threaded holes are arranged at the rear end of the welding frame. Rotating shafts are installed on the center faces of the two ends of the transverse limiting framework of the welding frame. By means of the welding tool, the consistency and welding efficiency of the standard knot expansion platform are improved.

Description

technical field [0001] The invention relates to the field of elevator construction, in particular to an elevator standard joint welding frock. Background technique [0002] Construction elevators, also known as construction elevators, are often used in construction sites for vertical transportation of people or goods. The elevator is formed by stacking and connecting multiple standard sections in sequence. By adding or deleting the number of standard sections, the guide rail of the elevator can be realized. The height adjustment of the frame and the welding precision of the standard section are required to be high, because the processing quality directly affects the quality of the whole machine and its working reliability. In order to facilitate the inspection, maintenance and construction of the elevator, during the construction of the elevator, according to the construction requirements Some standard sections have external extension platforms. [0003] The standard sectio...

Problems solved by technology

[0003] The standard section expansion platform is usually made by manual welding after the size is measured on the spot. During manual welding, the operator places the components of the standard section expansion platform on the tooling, positions them, firstly welds the front side manually, and then removes the frame from the Take off the tooling and complete the reverse welding. Manual welding has low production efficiency, unstable product quality, high labor cost and high labor intensity.
