DETAILED DESCRIPTION

[0015] In order to make those skilled in the art better understand the present invention, the present invention is further explained in detail below with reference to the accompanying drawings and embodiments. It should be noted that the features in the embodiments and embodiments of the present application can be combined with each other without conflict.

[0016] like Figure 1 As shown, a typical embodiment of the utility model provides a rapid prototyping device for an arc-shaped component of a pipeline support, comprising a base 1, a column 2, a cross beam 3, a groove plate 4, a flange plate 5 and a jacking device. The columns 2 are symmetrically arranged at both ends of the upper surface of the base 1, the cross beam 3 is arranged on the top of the column 2, the groove plate 4 is directly or indirectly connected to the bottom of the cross beam 3, the bottom of the jacking device is supported on the upper surface of the base 1, and the flange plate 5 is connected to the top of the jacking device. The bottom of the groove plate 4 is provided with an arc-shaped groove, and the upper part of the flange plate 5 has an arc surface adapted to the arc-shaped groove.

[0017] When in use, first count the number and model of arc-shaped component brackets according to the design drawings, select the specifications and sizes of the related components of the arc-shaped component rapid prototyping tooling that match them, and propose a material plan.

[0018] According to the selected matching tooling and its components, a rapid prototyping device for the arc-shaped components of the pipeline support is manufactured and installed, and a matching jacking device is selected.

[0019] According to the statistics of the number of arc-shaped plate components involved in the pipeline support, the materials are laid out and polished, and the matching pipeline support arc-shaped component rapid prototyping device is debugged and corrected by testing the first arc-shaped plate.

[0020] Then the curved plates of the pipe support are processed one by one, and safety protection measures such as isolation warning and personal labor protection products are taken. After the inspection and detection of the rapid prototyping device of the pipe support curved component is completed and the processing conditions are met, the jacking device is kept in the initial state, the component to be processed 8 is placed between the groove plate 4 and the flange plate 5 and temporarily fixed, and the jacking device is started to start processing and perform curvature monitoring.

[0021] For some curved plates of pipe supports that do not meet the requirements, fine-tuning is required. Finally, the curved plate supports are assembled and welded and inspected.

[0022] In a relatively specific implementation, a lining plate 9 is provided between the bottom of the cross beam 3 and the groove plate 4, and the cross beam 3, the lining plate 9 and the groove plate 4 are connected by bolts 10 to achieve the purpose of being detachable and replaceable.

[0023] In a relatively specific implementation, the flange plate 5 includes a bottom horizontal steel plate and an upper arc-shaped steel plate, and two ends of the upper arc-shaped steel plate are connected to two ends of the bottom horizontal steel plate.

[0024] In this embodiment, the lifting device is a selectively configured manual mechanical jack and an electric hydraulic jack 6.

[0025] First, use the electric hydraulic jack for processing. When the curvature accuracy of the curved plate of the pipe support does not meet the requirements, use the manual mechanical jack to replace the electric hydraulic jack to fine-tune the curved plates of the pipe support one by one until they meet the design requirements.

[0026] The following is an example of the implementation of the arc-shaped component rapid prototyping device for pipe supports in the 2200MTD urea project in Togliatti, Russia, undertaken by the applicant. The arc-shaped component supports involved in the pipe supports of this project mainly include various types of pipe supports, hangers, pipe clamps, etc., with specifications of different pipe diameters such as D15-DN1000. Due to the large variety of specifications of arc-shaped component pipe supports, the small number of local processing plants and the high cost, the utility model has the characteristics of simple assembly, fast processing speed, convenience and flexibility, and low cost, and has been widely used in the project prefabrication site.

[0027] 1. Preparation for prefabrication of pipe supports

[0028] In order to ensure the quality of pipeline installation, the manufacture and installation of pipe supports is extremely important. In order to speed up the construction progress, the support prefabrication is uniformly processed in the prefabrication yard outside the factory. After the pipeline drawings are reviewed, the selected pipe supports for the project are counted and a material plan is proposed based on the pipe supports and support atlas involved in the drawings. This on-site utility model involves a special classification of pipe supports with arc components, and counts their specifications, materials, and quantities. At the same time, the prefabrication yard plans the prefabrication site for pipe supports, and prepares temporary electricity, machinery and various auxiliary materials.

[0029] (II) Prefabrication of the rapid prototyping device for arc-shaped components of pipeline supports

[0030] Use H300*300*10*15 steel 6m, t=10mm steel plate 0.2m 2 ,t=20mm steel plate 1m 2 , prefabricate according to tooling drawings.

[0031] The base 1, column 2 and beam 3 are made of H300*300 steel, and the connection points are fully welded. 700*300*20 steel plate is used as lining plate.

[0032] The groove plate 4 is made of a 20mm steel plate with a groove, and the upper arc-shaped steel plate of the flange plate 5 is selected from a 20mm steel plate with an arc that matches the groove plate 4, and is matched and welded to a 500*200*20mm steel plate as the bottom horizontal steel plate.

[0033] The lifting device uses a 20T electric hydraulic jack and a 20T manual mechanical jack. The 20T electric hydraulic jack is connected to the electric hydraulic jack control system 7 through a hydraulic oil pipeline 11, and the electric hydraulic jack control system 7 is connected to the electric hydraulic jack control system motor 12.

[0034] Bolt 10 uses M20*50 high-strength bolts. The bolt holes involved need to be polished, and the other welding nodes must meet the quality requirements.

[0035] (III) Experiment and correction of the rapid prototyping device for arc-shaped components of pipeline supports

[0036] After prefabrication and inspection are completed, the power supply of the electric hydraulic jack control system is turned on, a DN500 pipe support arc plate is selected for preliminary testing, various performances of the tooling are tested, and the groove plate 4 and the flange plate 5 are corrected.

[0037] (IV) Processing of curved plate components of pipeline supports

[0038] This project involves DN15-DN1000 pipe supports with ribbed plates, DN100-DN500 bolt-fastened pipe clamps with curved plates and hangers. According to the statistical number of curved plates of pipe supports, they are cut and polished, and matching lining plates 9, groove plates 4, and 5-flange plates are selected for assembly, and the curvature is processed one by one using the calibrated tooling.

[0039] (V) Correction of curved plate of pipe support

[0040] The curvature of the partially processed curved plate of the pipeline did not meet the requirements. A manual mechanical jack was used to replace the original electric hydraulic jack of the processing tooling for secondary processing to ensure the processing accuracy of the curved plate of the pipeline support.

[0041] (VI) Prefabrication of pipe supports with curved plates

[0042] After the arc plates of each pipe support are processed and tested, they are welded or assembled according to the pipe support atlas. Some welds that require non-destructive testing are tested according to the design requirements, and finally the pipe support is accepted as a whole.

[0043] The scope of protection claimed by the present invention is not limited to the above specific implementation methods. For those skilled in the art, the present invention may have various deformations and changes. Any modification, improvement and equivalent substitution made within the concept and principle of the present invention should be included in the protection scope of the present invention.
