Embodiment Construction

[0024] Such as Figure 1-Figure 2 As shown, the present invention comprises: base plate 1, four rollers 2 are installed as the support of base plate 1 at the bottom of base plate 1, and four rollers 2 are arranged along the four corner directions of base plate 1; A small round hole is respectively arranged on the base plate 1, and a nut 3 is respectively welded at the place of each small round hole. After the threaded rod 4 passes through the screw hole of the nut 3 and the small round hole on the base plate 1, a conical support 5 is welded at the lower end of each threaded rod 4, and a rotary handle 6 is welded and fixed at the screw rod 4 upper end.

[0025] Another embodiment is: screw holes are directly provided on the bottom plate 1 adjacent to each roller 2, and the screw rod 4 directly passes through the screw holes.

[0026] The reason why the present invention is provided with two support structures of roller 2 and conical support 5 is: when using the present inventi...

Abstract

The invention relates to a flange pairing device, which is provided with a bottom plate and two vertical support arms, wherein the two vertical support arms mutually correspond and are fixedly arranged on the bottom plate; the lower part of the bottom plate is provided with a plurality of support rollers, the bottom plate which is adjacent to the support rollers is respectively provided with a first screw hole, and a screw rod is matched with the first screw hole and passes through the first screw hole; one side of each vertical support arm is respectively provided with a second screw hole, wherein an adjusting screw rod is matched with the second screw hole and passes through the second screw hole; the vertical support arms are respectively provided with an adjusting slot hole, wherein a horizontal support device is arranged in each adjusting slot hole; and the horizontal support device comprises a horizontal support arm, wherein the upper surface of the horizontal support arm is fixedly provided with a vertical adjusting screw rod and a vertical support plate, the vertical support plate is provided with a horizontal slot hole, and a plurality of flange support screw rod and nut pairs are arranged in the horizontal slot hole. Due to the adoption of the technical scheme, the invention has the advantages of simple structure and convenience for operation; meanwhile, the production cost and the labor intensity of operation personnel are reduced, the flange pairing efficiency is improved.

Description

technical field [0001] The invention relates to flanges, in particular to a flange pairing device. Background technique [0002] At present, process pipelines are used in various industries, especially in the fields of petroleum and chemical industry, which require prefabrication and installation of a large number of pipelines of different materials and sizes. In the pipeline system, the use of a large number of flanges is essential, so the combination of flanges is involved. Flange pairing refers to the combination of flanges and pipelines or flanges and elbows and other workpieces. Among them, the pairing connection of flanges and pipelines is the most common. [0003] The precision of the flange assembly is very high, and there are strict requirements on the amount of misalignment of the assembly, the clearance of the assembly, and the levelness and verticality of the flange. For example: on offshore oil platforms, the general requirements are: carbon steel flanges and ...
