Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] The frame overturning method disclosed in the present invention is applicable to various heavy-duty frames. In this embodiment, an elliptical die forging press frame is taken as an example, and its overturning method is carried out according to the following steps.

[0021] a. Set up the support column 7 inside the foundation pit 1, turn the assembled frame 1 onto the support column 7 with the cooperation of auxiliary parts and the flipping mold. The auxiliary parts are generally tools such as backing plates and jacks, and turn over the mold And the backing plate is a traditional arc structure. Frame 1 side stands on support column 7, as attached figure 1 location shown.

[0022] b. Install the overturn bracket 6 at the mouth of the foundation pit 1 and on both sides of the frame. The overturn bracket 6 is fixed with the rotating support 4. In ...

Abstract

The invention relates to a method for laterally turning a heavy rack. According to the method, a support upright is built inside a foundation trench, the rack is turned to the support upright, a turning bracket is arranged at a foundation trench opening, an inner support is arranged inside the rack, and the inner support is connected with a rotary support; a hanging point is selected from the tail part of the rack so as to connect the rack with a crown block; the support upright is removed, and the rack turns under the action of self-gravity of the rack; and after the rack is turned, a temporary support device is installed, the turning bracket is removed, and the temporary support device is removed under the matching of a jack. According to the turning method, the heavy rack can be installed in a common workshop under the condition that a workshop structure is not dismounted, the work height is lowered, the construction difficulty and the risk of work high above the ground are reduced, the rack can be turned only by using the workshop crown block and without a large crane and heavy hydraulic lifting and hydraulic sliding devices, the construction cost is reduced, the construction efficiency is improved, the time limit for a project is shortened, the controllability is strong, the safety and the reliability of the construction site are improved, and the method is suitable for turning various heavy racks.

Description

technical field [0001] The invention relates to a rack overturning method in the field of manufacturing and installing heavy-duty rack equipment, in particular to a sideways overturning method for a heavy-duty rack. Background technique [0002] At present, for heavy-duty racks with a weight of more than 1,000 tons, hydraulic lifting and hydraulic pushing are mainly used for installation in China. This method requires the manufacture and installation of a high-level steel frame for lifting to arrange hydraulic lifting devices. Therefore, it is necessary Higher plant layout. For ordinary plant structures, using this installation method requires demolition of part of the plant structure, and the use of a large crane to cooperate with the installation of the lifting frame structure. In addition, due to the weight limit of the frame itself, heavy hydraulic lifting and hydraulic sliding devices are required. Therefore, the machine The investment of frame turning is large, and th...
