[0022] The first sleeve piece 3 one end facing the second sleeve piece 4 is slid to connect link sleeve piece 5 one end, and the outer wall of the second sleeve piece 4 one end facing the first sleeve piece 3 is equipped with the groove 9 of the slide sleeve connection with link sleeve piece 5 other end forms, and the lateral wall of link sleeve piece 5 is equipped with a plurality of limiting strip holes 6, and the outer wall of second sleeve piece 4 is correspondingly equipped with a plurality of limiting studs 7, and a plurality of limiting studs 7 are commonly connected limiting sleeve 8 through the nut, and the inner wall of limiting sleeve 8 and the lateral wall of groove 9 jointly form the inside and outside clamping of link sleeve piece 5 end part.

[0023] In actual use, first, the one end of link sleeve piece 5 is clamped by the inner wall of limiting sleeve 8 and the lateral wall of groove 9 to ensure that the first sleeve piece 3 facing the second sleeve piece 4 forms an overall structure through link sleeve piece 5, and the two pipelines to be welded are placed in the inner cavities of the first sleeve piece 3 and the second sleeve piece 4 respectively, and the position of the two pipeline end parts forming butt joint is located between the first sleeve piece 3 and the second sleeve piece 4.

[0024] In this process, it is necessary to judge whether the two side pipes are coaxially arranged by the fitting degree of the first sleeve 3, the second sleeve 4 and the outer wall of the pipe, so as to indicate the problem of inclination of the pipe port. Then, the nut of the limiting column 7 is driven by a wrench or a device to release the clamping of the limiting sleeve 8 on the connecting sleeve 5, and the connecting sleeve 5 is pushed to move and slide towards the first sleeve 3, so that the connecting sleeve 5 contacts and surrounds the butt joint ports of the two side pipes, so as to facilitate the subsequent welding operation.

[0025] The oil and gas storage and transportation pipe butt joint device provided by the application provides a support surface for the two pipes to be butt jointed by the first sleeve 3 and the second sleeve 4. On the basis of the fitting of the outer wall of the pipe and the inner wall of the first sleeve 3 and the second sleeve 4, the operation requirement of keeping the two side pipes coaxially arranged is ensured. At the same time, by setting the sliding sleeve connecting sleeve 5, the butt joint ports of the two side pipes are always in an open-air state during the welding operation.

[0026] Among them, in order to improve the convenience of moving the connecting sleeve 5, an operation handle 12 is arranged on the outer wall of the connecting sleeve 5, which is convenient for the staff to control the relative position of the connecting sleeve 5.

[0027] Specifically, in order to prevent the outer wall of the oil and gas storage and transportation pipe in the first sleeve 3 and the second sleeve 4 from having corrosion and waterproof coating, and to improve the smoothness of the pipe during the movement of the first sleeve 3 and the second sleeve 4, a plurality of rollers 10 are arranged on the inner wall of the first sleeve 3 and the second sleeve 4. The inner circumferential surface of the plurality of rollers 10 forms a receiving surface for receiving the pipe. In the specific use process, the first sleeve 3 and the second sleeve 4 respectively bear the end portions of the two pipes, and the built-in rollers 10 are used to adjust the relative position of the device and the pipe, and to adjust the distance between the two pipes.

Not only can the pipe be flexibly extruded from both sides to realize the stable pipe while avoiding scratching the pipe, but also can meet the use of pipes of various diameters.

[0029] Meanwhile, considering the convenience in the pipe laying process, the longitudinal section of the first sleeve 3 and the second sleeve 4 adopts a semi-circular ring structure, so that the staff can accurately determine the relative position of the pipe relative to the first sleeve 3 or / and the second sleeve 4, even if the position is adjusted, the working efficiency is improved.

[0030] Considering that each time the pipe butt joint operation is carried out, a pit is dug at the pipe butt joint position by using an excavator and manual digging, so as to facilitate subsequent manual welding and pipe butt joint operation, and considering that the distance between the pipe and the pit bottom cannot be guaranteed during the on-site construction process, and the levelness of the pit bottom cannot be guaranteed, the supporting rod 2 comprises a first hydraulic cylinder 201, the first hydraulic cylinder 201 comprises a sleeve part and a telescopic stem part in sliding sleeve connection, the free end of the telescopic stem part of the first hydraulic cylinder 201 is connected with the pipe wall of the first sleeve 3 or the second sleeve 4, and the free end of the sleeve part of the first hydraulic cylinder 201 is connected with the base 1, so as to adjust the height difference of the first sleeve 3 and the second sleeve 4 relative to the base 1.

[0031] Meanwhile, considering that the levelness of the pit bottom is also difficult to guarantee, the free end of the telescopic stem part of the first hydraulic cylinder 201 is connected with the pipe wall of the first sleeve 3 or the second sleeve 4 through a hinge shaft, and the free end of the sleeve part of the first hydraulic cylinder 201 is connected with the base 1 through a hinge shaft.

[0032] The supporting rod 2 further comprises a second hydraulic cylinder 202, the second hydraulic cylinder 202 comprises a sleeve part and a telescopic stem part, the free end of the telescopic stem part of the second hydraulic cylinder 202 is connected with the side wall of the sleeve part of the second hydraulic cylinder 202 through a hinge shaft, and the free end of the sleeve part of the second hydraulic cylinder 202 is connected with the base 1 through a hinge shaft.

[0033] In the case that the base 1 cannot be horizontally placed, the included angle between the axis of the first sleeve 3 and the second sleeve 4 and the base 1 can be directly adjusted through the second hydraulic cylinder 202 and the first hydraulic cylinder 201, so that the axis of the first sleeve 3 and the second sleeve 4 always remains in a horizontal state, thereby guaranteeing the operation requirement of horizontal welding of the pipes on both sides.
