Problems solved by technology

[0004] The use of trusses is huge. According to our preliminary calculations, to meet both the strength requirements for the stability of the C-shaped plate and the rigidity requirements for the precise positioning of the C-shaped plate, about 2,200 tons of trusses are required. Calculated at 30,000 yuan / ton, only the stable truss One item requires about 66 million yuan in tooling costs; since the truss is installed around the press, it is necessary to set up complicated hoisting passages for heavy parts, which not only requires high technical requirements for truss erection, but also makes the hoisting process of heavy parts more complicated

Embodiment 1

[0031] Such as figure 1 As shown, the built-in truss when the C-shaped plate is installed includes an intermediate truss 7 perpendicular to the ground. The two sides of the truss 7 are symmetrically provided with diagonal braces 1, one end of the diagonal brace 1 is fixed to the middle truss 7, and the other end is fixed to the ground; several layers of working platforms parallel to the ground are arranged on the middle truss 7, and each layer works The platform is arranged symmetrically on both sides of the middle truss 7 , and one end of the working platform is fixed to the middle truss 7 , and the other end is set outside the middle truss 7 , and the working platform is arranged above the diagonal brace 1 . For the convenience of description, the diagonal brace 1 is divided into left and right diagonal braces. Considering that the truss needs to bear the partial load of the C-shaped plate, and the overall height of the truss is 28.9m, in order to improve the overall stabili...

Embodiment 2

[0092] When hoisting the C-shaped plate, use step (a) to hoist all the C-shaped plates with one part of the four parts. The end face of each C-shaped plate is in contact with the second-layer working platform 5, and the side wall is in contact with the corresponding working platform at the same time. The working platform 6 of the first floor and the working platform 4 of the third floor are in contact. After the inside of the opening of the C-shaped plate is in contact with the working platform 3 of the fourth floor, the C-shaped plate is vertically lowered and snapped into the groove installed at the bottom of the built-in truss. Realize the installation and fixation of the C-shaped plate, and then use the bolts to penetrate and fix all the C-shaped plates in this part as a whole, and then lift and fix the C-shaped plate in turn according to the above actions for the remaining three parts. The C-shaped boards all adopt hoisting to fix the C-shaped boards of this part and then ...

Abstract

The invention discloses a built-in truss used during installation of C-shaped plates and a hoisting method for the same. The built-in truss comprises a middle truss perpendicular to the ground, and a plurality of frame-shaped truss units are sequentially connected to form the middle truss; inclined struts are symmetrically arranged on two side surfaces of the middle truss; and a plurality of layers of working platforms parallel to the ground are arranged on the middle truss, each layer of working platforms is symmetrically arranged on two sides of the middle truss, one end of each working platform is fixed to the middle truss, and the working platforms are disposed above the inclined struts. The hoisting method includes that a traveling crane perpendicularly hoists the C-shaped plates; openings of the C-shaped plates face the middle truss; the traveling crane translates the C-shaped plates; and the C-shaped plates perpendicularly descend after being in contact with the corresponding working platforms, so that the C-shaped plates are fixedly installed. The built-in truss and the hoisting method have the advantages that influence of weights of the C-shaped plates is avoided, the C-shaped plates are stressed by lateral force for preventing the C-shaped plates from tipping, and requirements of the C-shaped plates on the rigidity and the strength of the truss are lowered; the difficult problem of high-altitude construction is solved; and installation cost is saved.

Description

technical field [0001] The invention relates to the field of tooling, in particular to a built-in truss and a hoisting method for a C-shaped plate when installing a C-shaped plate. Background technique [0002] The C-shaped plate of the large die forging press is an important part of the forging press. The installation of the C-shaped plate is the key point of the entire rack installation. Since the C-shaped plate is a thin-walled, slender rod with heavy weight at both ends, the deformation of the C-shaped plate is controlled during the process of turning from the side to the stand (refer to The elastic deformation of the C-shaped plate and the direction of deformation) and the control of the impact and shaking of the C-shaped plate during the process of turning over the center of gravity are the difficulties in the installation of the C-shaped plate. After controlling the deformation of the C-shaped plate, the accuracy of the rack installation (the gap between the C-shaped...
