Problems solved by technology

The former is difficult to hoist due to the huge size and overweight of the end plate body. If hoisting needs to design special lifting lugs and weld them on the end plate body before hoisting, it is time-consuming, labor-intensive, and has potential safety hazards; the latter will cause serious increase. The problem of cost, the process is cumbersome, and the construction period is delayed. If there is a mistake in the vertical lathe processing, the light one will be repaired, and the serious one will cause the product to be scrapped.

Embodiment 1

[0040] Example 1: Fabrication of End Disc Body

[0041] Place an I-beam support on the ground foundation. The I-beam support is composed of 20#B I-beam with a length of 300mm and a steel plate welded to the bottom of the I-beam with a size of 10×150×250mm. Place it on the I-beam support, mark the position line of the reinforcement partition on the lower cover, and then adjust the I-beam support so that it corresponds to the reinforcement partition inside the end plate body, and place 2 pieces of work at each reinforcement partition position. Character steel support, a total of 12 pieces. The I-beam support is fixed with the ground foundation and the lower cover is super flat. On the basis of the ultra-flat lower cover plate, assemble the remaining parts of the end plate body.

Abstract

The invention relates to the simulation tooling of the backing plate outside the end plate body and its application. The surface of the peripheral plate of the end plate body is evenly welded with n pieces of backing plates. In the groove, the simulated tooling simulates the ring track outside the end plate of the real C-type rotor dumper, and can indirectly measure the distance between the inner side of the ring track and the middle slot of the backing plate, so as to manufacture the backing plate according to the actual situation, so as to ensure The ring track fits tightly with the backing plate. The simulated tooling of the backing plate on the outer side of the end plate body according to the present invention is made of common materials, and the cost is low. The components are connected by welding and bolts, and the slider and the square groove slideway do not need to be precisely matched, so the manufacturing difficulty is small. The installation of the simulated tooling of the backing plate outside the end plate does not require hoisting or dismantling of the end plate, which reduces safety hazards, reduces manufacturing costs, shortens the construction period and ensures product quality. The whole process has small safety hazards, low cost, simple procedures, and short construction period.

Description

technical field [0001] The invention relates to the field of mechanical structure processing and transformation, in particular to a simulation tool for making the outer backing plate of the end plate of a C-type rotor dumper and its application. Background technique [0002] The end plate body is an important part of the C-type rotor dumper. It mainly adopts an unclosed C-shaped box beam structure with a diameter of more than 7000mm and is a fully welded structure. There are many reinforced partitions installed inside the end plate body. The plate will inevitably cause a certain amount of deformation of the C-shaped box beam during the welding process. If it is well controlled, the shape of the C-shaped end plate can be approximated to a perfect circle, and the peripheral plate will produce a small welding deformation. A large number of backing plates are installed on the peripheral plate of the C-shaped end plate body, and the ring track and the backing plate are connected ...
