Description

Technical Field

[0001] The utility model relates to the technical field of long-distance pipeline management, in particular to a long-distance pipeline management clamp. Background Art

[0002] Long-distance pipelines refer to pressure pipelines designed according to GB50251 and other specifications, used to transport oil and gas commodity media between production sites, gas storage facilities, and user units. Long-distance pipeline management is a key task to ensure energy security, protect the ecological environment, and prevent accidents and disasters. At present, long-distance pipelines usually require clamps to assist in positioning after welding maintenance and management.

[0003] A Chinese patent discloses a pipeline welding fixture (authorization announcement number CN221110520U), which includes a base plate, two mounting seats slidably installed on the upper surface of the base plate, and a rotating disk rotatably installed in the mounting seat, which is used to limit the pipeline and drive the pipeline to rotate; four mounting plates are slidably installed in the rotating disk, and two limiting columns are rotatably installed between the mounting plates. The outer surface of the limiting column is in active contact with the outer surface of the pipeline, which is used to limit the pipeline. During use, when the outer surface of the limiting column contacts the outer surface of the pipeline, the pipeline cannot move. When the outer surface of the limiting column does not contact the outer surface of the pipeline, the pipeline can move, thereby limiting the pipeline.

[0004] Since the above-mentioned device uses a closed-loop structure to lock the pipeline, the pipeline can only be moved out of the clamp along the axis of the pipeline after welding is completed. This requires that there is enough space around the pipeline for the pipeline to move out of the clamp, which will limit the working environment of pipeline welding and make it difficult to meet the working requirements in a narrow environment.

[0005] Therefore, a long-distance pipeline management clamp is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present invention is to provide a long-distance pipeline management fixture in order to solve the above-mentioned problem, thereby improving the problem that the existing fixing fixtures used for long-distance pipeline welding management need to occupy a large space.

[0007] The utility model achieves the above-mentioned purpose through the following technical scheme: a long-distance pipeline management clamp, comprising: two lower arc trough plates and two upper arc trough plates, the top of one of the upper arc trough plates is fixedly connected to a first servo motor, the end of the output shaft of the first servo motor is fixedly connected to a first threaded rod, the surface of the first threaded rod is threadedly connected to a threaded sleeve fixedly connected to one of the lower arc trough plates, a telescopic rod is fixedly connected between the other lower arc trough plate and the other upper arc trough plate, and a spacing adjustment mechanism is installed between the two upper arc trough plates. On the basis of keeping the pipeline translated out of the clamp along the direction of the pipeline axis, the staff still moves the clamp or the pipeline in the direction perpendicular to the pipeline axis to ensure that the clamp can be easily loaded and unloaded even in a small space. This not only expands the scope of application of the clamp, but also adopts a design that is easy to move, which can speed up the rate at which the staff transports the clamp and improve the efficiency of the use of the clamp.

[0008] Preferably, a threaded hole is provided at one end of the other upper circular arc trough plate, and the spacing adjustment mechanism includes a second threaded rod threadedly connected to the inside of the threaded hole, and one end of the second threaded rod is fixedly connected to a second servo motor fixedly connected to one of the upper circular arc trough plates. The spacing adjustment mechanism can not only connect the two upper circular arc trough plates together at the same time, so that the first servo motor can simultaneously drive the two upper circular arc trough plates to lock the two pipes respectively, so as to improve the fixing efficiency of the pipes, but also the staff can use the spacing adjustment mechanism to dock the pipes that have not been successfully docked together, so as to reduce the subsequent docking difficulty of the staff.

[0009] Preferably, a guide hole is opened at one end of the other upper circular arc trough plate, and the inside of the guide hole is slidably connected to a guide rod fixedly connected to one of the upper circular arc trough plates, which can prevent one of the upper circular arc trough plates from rotating or shifting, so as to ensure that the upper circular arc trough plate can stably clamp the pipeline.

[0010] Preferably, a guide slope is provided on the side end of the lower arc trough plate away from the threaded sleeve, and the angle between the guide slope and the horizontal plane is thirty degrees, which can reduce the difficulty of moving the lower arc trough plate to the bottom of the pipeline, so as to facilitate installation by the staff.

[0011] Preferably, the opposite ends of the lower arc trough plate and the upper arc trough plate are embedded with evenly distributed rubber resistance-increasing blocks, and the cross-sectional shape of the rubber resistance-increasing blocks is spherical, which can improve the stability of the lower arc trough plate and the upper arc trough plate in clamping the pipeline.

[0012] Preferably, evenly distributed balls are embedded in the bottom of the lower circular arc groove plate, and the center point of the balls is set inside the lower circular arc groove plate, which can reduce the resistance during the movement of the lower circular arc groove plate and make the entire fixture easy to move.

[0013] Preferably, the telescopic rod includes a rectangular sleeve fixedly connected to the top of the other lower arc trough plate, and the interior of the rectangular sleeve is slidably connected to a rectangular rod fixedly connected to the other upper arc trough plate.

[0014] The beneficial effects of the utility model are:

[0015] 1. While the pipe is being moved out of the fixture along the axis of the pipe, the staff still moves the fixture or pipe in the direction perpendicular to the axis of the pipe, so that the fixture can be easily loaded and unloaded even in a small space. This not only expands the scope of application of the fixture, but also adopts a design that is easy to move, which can speed up the staff's transfer of the fixture and improve the efficiency of the fixture.

[0016] 2. The spacing adjustment mechanism can not only connect the two upper arc groove plates together at the same time, so that the first servo motor can simultaneously drive the two upper arc groove plates to lock the two pipes respectively, so as to improve the fixing efficiency of the pipes, but also the staff can use the spacing adjustment mechanism to connect the pipes that have not been successfully connected together, so as to reduce the difficulty of subsequent connection for the staff.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] When implementing: Figure 1-4 As shown, a long-distance pipeline management fixture includes: two lower circular arc trough plates 1 and two upper circular arc trough plates 2, wherein a first servo motor 3 is fixedly connected to the top of one of the upper circular arc trough plates 2, a first threaded rod 4 is fixedly connected to the end of the output shaft of the first servo motor 3, a threaded sleeve 5 fixedly connected to one of the lower circular arc trough plates 1 is threadedly connected to the surface of the first threaded rod 4, a telescopic rod 6 is fixedly connected between the other lower circular arc trough plate 1 and the other upper circular arc trough plate 2, and a spacing adjustment mechanism 7 is installed between the two upper circular arc trough plates 2;

[0024] The staff first pushes the two lower arc trough plates 1 to the bottom of the two pipes respectively, and fits the arc groove of the lower arc trough plate 1 with the lower surface of the pipe, and then manually controls the first servo motor 3 to rotate in the corresponding direction. The first servo motor 3 drives the first threaded rod 4 to move downward along the threaded sleeve 5, and the first threaded rod 4 drives one of the upper arc trough plates 2 to move downward. One of the upper arc trough plates 2 drives the other upper arc trough plate 2 to move downward synchronously through the spacing adjustment mechanism 7, until the arc grooves of the two upper arc trough plates 2 are respectively pressed against the lower surface of the pipe. At this time, the pipe is firmly locked between the lower arc trough plate 1 and the upper arc trough plate 2.

[0025] like Figure 2 、 Figure 3 and Figure 4 As shown, a threaded hole 21 is formed at one end of the other upper circular arc trough plate 2, and the spacing adjustment mechanism 7 includes a second threaded rod 71 threadedly connected to the inside of the threaded hole 21, and one end of the second threaded rod 71 is fixedly connected to a second servo motor 72 fixedly connected to one of the upper circular arc trough plates 2; a guide hole 22 is formed at one end of the other upper circular arc trough plate 2, and a guide rod 73 fixedly connected to one of the upper circular arc trough plates 2 is slidably connected inside the guide hole 22;

[0026] When the staff needs to dock two locked pipes together, the staff only needs to manually control the second servo motor 72 to rotate in the corresponding direction. The second servo motor 72 drives the second threaded rod 71 to rotate. The second threaded rod 71 actively moves the other upper arc groove plate 2 through the threaded hole 21. At this time, the distance between the two upper arc groove plates 2 gradually decreases, and the upper arc groove plate 2 cooperates with the corresponding lower arc groove plate 1 to drive the pipe gradually close to the other pipe until the two pipes are docked together. At this time, the staff can perform welding operations normally.

[0027] like Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a guide slope 11 is provided at the side end of the lower arc groove plate 1 away from the threaded sleeve 5, and the angle between the guide slope 11 and the horizontal plane is thirty degrees; the opposite ends of the lower arc groove plate 1 and the upper arc groove plate 2 are embedded with evenly distributed rubber resistance-increasing blocks 8, and the cross-sectional shape of the rubber resistance-increasing blocks 8 is spherical; the bottom of the lower arc groove plate 1 is embedded with evenly distributed balls 9, and the center point of the balls 9 is set inside the lower arc groove plate 1; the telescopic rod 6 includes a rectangular sleeve 61 fixedly connected to the top of the other lower arc groove plate 1, and the interior of the rectangular sleeve 61 is slidably connected to a rectangular rod 62 fixedly connected to the other upper arc groove plate 2.

[0028] Based on the above characteristics, when the staff completes the welding operation of the two pipes, the staff first manually controls the first servo motor 3 to rotate in the opposite direction, and the first servo motor 3 drives the first threaded rod 4 to move upward along the threaded sleeve 5, and the first threaded rod 4 drives one of the upper arc trough plates 2 to move upward, and one of the upper arc trough plates 2 drives the other upper arc trough plate 2 to move upward synchronously through the spacing adjustment mechanism 7. When the spacing between the lower arc trough plate 1 and the adjacent upper arc trough plate 2 is greater than the diameter of the pipe, the staff can push the pipe out of the lower arc trough plate 1 away from the threaded sleeve 5 or pull the lower arc trough plate 1 out from under the pipe. While maintaining the removal plan of the pipe moving horizontally out of the lower arc trough plate 1 and the upper arc trough plate 2 along the axis of the pipe, the staff still moves the clamp or pipe in the direction perpendicular to the axis of the pipe to ensure that the clamp can be easily loaded and unloaded even in a small space. This not only expands the scope of application of the clamp, but also adopts a design that is easy to move, which can speed up the rate at which the staff transports the clamp and improves the efficiency of the clamp.

[0029] It should be noted that the first servo motor 3 and the second servo motor 72 in the above description are both devices with relatively mature applications in existing technologies. The specific models can be selected according to actual needs. At the same time, the first servo motor 3 and the second servo motor 72 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0030] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
