Welding tool of standard knot square frame of construction lift and welding method thereof

Abstract

The invention provides a welding tool of a standard knot square frame of a construction lift. The welding tool comprises a turning component, a revolving arm, two clamping devices and two position changing mechanisms, wherein the turning mechanism is provided with a rotating shaft; the revolving arm is connected to the rotating shaft of the turning component; the two position changing mechanisms are arranged at the two ends of the revolving arm respectively and are provided with a rotating shaft respectively; the two clamping devices are connected to the rotating shafts of the two position changing mechanisms respectively; the rotating shaft of the turning component drives the revolving arm, the two clamping devices and the two position changing mechanisms to turn together during rotation; the rotating shafts of the two position changing mechanisms drives the two clamping devices to rotate respectively during rotation. The welding tool can realize simultaneous manual feeding and automatic welding; an operator can operate the operations of two stations by standing at the same position, so that the labor intensity is reduced. The invention also provides a welding method using the welding tool.

Description

technical field [0001] The invention relates to the technical field of elevators, in particular to a welding tool for welding a standard section frame of a construction elevator and a welding method thereof. Background technique [0002] The construction elevator is a manned and cargo-carrying construction machine often used in construction sites. It mainly plays the role of transporting building materials to the high altitude. It is mainly composed of a guide rail frame, a cage, and a driving body. The up and down movement of the construction elevator is mainly driven by a motor. The cooperation between the gear and the rack is realized. Therefore, the installation accuracy of the rack is very critical for the smooth and safe movement of the construction elevator. The installation accuracy of the rack is mainly affected by the welding accuracy of the standard joint and the rack pad. [0003] The guide rail frame of the construction hoist is mainly composed of multiple stand...

Problems solved by technology

[0004] However, manual welding has low production efficiency, unstable product quality, high labor costs, high labor intensity and poor working conditions

In the single-station mode of semi-automatic welding, the loading and clamping and welding operations can only be carried out sequentially, and the production efficiency is low; in the double-station mode of semi-automatic welding, since one welding robot is shared, the two stations are in a straight line in space Arranged or approximately linearly arranged, the same worker loads and unloads materials back and forth at two stations, the labor intensity of the workers is high, and the efficiency is also affected
