Embodiment 1

[0029] In the installation process of skid-mounted devices, there are usually small batches and small-diameter pipe flanges of the same pipe diameter paired. At present, the matching between the connecting pipe and the flange is often based on manual matching. The efficiency of manual matching is low, and it is greatly affected by human factors. The consistency of the connecting gap between the connecting pipe and the It is difficult to guarantee the alignment and misalignment with the flange. In order to solve the defects of the manual assembly method, reduce the influence of human factors, improve the quality and efficiency of the connection flange assembly, realize the semi-automation of the assembly construction, and meet the construction requirements, this embodiment provides a connection flange assembly device. The takeover flange pairing device is mainly composed of L-shaped operating platform 10, fixed support 11, rail 9, flange fixing 4, flange 5, rotating shaft 13, ...

Embodiment 2

[0040] The flange fixing part 4 described in this embodiment is a three-jaw chuck, such as Figure 4 As shown, there is no pin shaft linkage mechanism 6 and cross groove structure on the three-jaw chuck. The rapid positioning of the workpiece flange 5 and the connecting pipe 7 is realized through the three-jaw chuck. Wherein the three claws on the three-jaw chuck fix the flange 5 through the outer diameter of the flange 5, which is mainly used for the combination of the flange 5 and the connecting pipe 7 with a smaller outer diameter. Refer to Embodiment 1 for the fitting device and usage method of connecting flanges in this implementation.

Embodiment 3

[0042] In order to further illustrate the beneficial effects of the connection flange assembly device of the present invention, this embodiment provides a manual assembly method and a time-consuming comparative experiment using the connection flange assembly device of the present invention.

[0043] In this embodiment, statistics are made on the time-consuming of groups of 10 DN40 sockets. Among them, the manual pairing method requires the cooperation of two riveters and welders during the pairing construction; when using the joint flange pairing device of the present invention, only one welder is required to operate. See Table 1 for the time-consuming statistical results of the manual pairing method, and see Table 2 for the time-consuming statistical results of using the connecting flange assembly device of the present invention. It can be seen from Table 1 that the total time-consuming of manual pairing is 35 minutes. It can be seen from Table 2 that it takes 11 minutes to ...

Abstract

The invention discloses a connecting pipe and flange assembling device, belongs to the technical field of oil and gas field connecting pipe assembling, and aims to solve the problems that manual connecting pipe flange assembling efficiency is low through a skid mounted unit and assembling quality is difficult to guarantee. The assembling device comprises an L-shaped operating platform, a fixing support member, a rail, a flange fixing member, a flange, a rotary shaft, a locking nut, a planar pushing ball bearing, a deep groove ball bearing and the like. According to the device, by controlling the coaxiality during connecting pipe and flange assembling, high accuracy of connecting pipe and flange assembling is guaranteed, and consistence requirements of assembling gaps and unfitness of butt joint in the same batch can be improved; in addition, by adjusting the device once, rapid assembly of connecting pipes and flanges in batches can be implemented, labor force is saved, and assembling efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of connecting pipe installation in oil and gas fields, and relates to a connecting device for connecting flanges, in particular to a semi-automatic connecting device for connecting connecting pipes and flanges in a skid-mounted device. Background technique [0002] Skid-mounted devices have been widely used in oil and gas fields, and the installation of skid-mounted devices mainly includes the installation of pressure vessels and pressure joints. The installation feature of the connecting pipe of the skid-mounted device is that the diameter of the connecting pipe is relatively small, there are many pipelines with the same diameter, and each section of the connecting pipe is relatively short, and the connecting valves between the connecting pipes are mainly flange valves. [0003] In the installation process of skid-mounted devices, there are usually small batches and small-diameter pipe flanges of the same p...
