Problems solved by technology

However, the special-shaped beam structure is large, and its L dimension can usually reach more than 7 meters. The overall clamping on the bed requires turning around and secondary processing, which is labor-intensive, time-consuming and inefficient, and it is difficult to grasp the result error fluctuation and dimensional reliability.
In addition, the operation of inspecting several critical dimensions after subsequent processing is also very difficult

Embodiment Construction

[0037] The core of the present invention is to provide a special welding tool for the processing of special-shaped beams of the ring cooler, which can greatly improve the working efficiency while ensuring the processing accuracy of the special-shaped beams.

[0038] Without loss of generality, this embodiment will be described in detail below in conjunction with the accompanying drawings.

[0039]First of all, it needs to be clarified that the basic functional components of the annular cooler involved in this article and their mutual position and connection relationship are the same as those of the prior art. The annular cooler is roughly divided into high temperature zone, medium temperature zone, low temperature zone and non-cooling mere. During the working process, the trolley and the support beam rotate around the center of the ring cooler in real time at a constant speed, and the middle of the front end of each trolley body is equipped with a hinged seat for connection wi...

Abstract

The invention discloses an exclusive welding tool for an annular cooler special-shaped beam. A beam body bearing thereof is used to bear and position the beam body of the special-shaped beam; an upper surface thereof is provided with a first position limitation part adapted with an adapter positioning hole in the bottom of the beam body; two flange end plate bearings thereof are respectively used to bear the inside and outside flange end plates of the special-shaped beam; the opposing side surfaces of the two flange end plate bearings are respectively provided with a second position limitation part adapted with the flange hole group of the corresponding flange end plate; the height from the upper surface of the beam body bearing to the second position limitation part is consistent with the height from the bottom surface of the beam body to the flange hole group on the corresponding flange end plate; and the lengths from the first position limitation part on the beam body bearing to the opposing side surfaces of the two flange end plate bearings are respectively consistent with the lengths from the adapter positioning hole in the bottom of the beam body to the flange surfaces of the inside and outside flange end plates. The exclusive welding tool greatly improves operating efficiency while ensuring processing accuracy for the special-shaped beam. Based on the exclusive welding tool, the invention also provides a processing technology for an annular cooler special-shaped beam.

Description

technical field [0001] The invention relates to the processing and manufacturing technology of a ring cooler, in particular to a processing technology of a special-shaped beam of a ring cooler and a special welding tool thereof. Background technique [0002] As we all know, the rotary part of the ring cooler is composed of a special-shaped beam, a rotary frame, a trolley and a fence, etc. For details, please refer to figure 1 , which shows the axonometric schematic diagram of the overall structure of the existing special-shaped beam. [0003] Specifically, the special-shaped beam is mainly composed of inner and outer slab columns, roof-shaped structure, liner, sealing body bracket, guide seat, sealing plate installation strip, beam body 10 and inner and outer flange end plates 20 and other structures. In the whole assembly relationship, the special-shaped beam is one of the key components of the liquid-sealed ring cooler. On the one hand, a bottom central hole and four tro...
