Some embodiments of the present invention will be described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

The embodiment provides a damping device, which is used for laying an electric power or gas pipeline, and as shown in fig. 1 and fig. 2, the damping device comprises a bracket 10, the bracket 10 comprises a base 100 and a roller 200, and the roller 200 is pivoted to the base 100; the base 100 has a resting surface; the base 100 includes a blocking portion oppositely disposed to protrude from the roller 200 in a radial direction of the roller 200, for preventing the duct 20 from being separated from the roller 200.

When the fairing is used, the resting surface of the base 100 can be placed on the ground; and, gyro wheel 200 pin joint is in base 100, through placing pipeline 20 in gyro wheel 200, when drawing and establishing pipeline 20, gyro wheel 200 will rotate under the tractive effect of pipeline 20, converts the friction between pipeline 20 and the ground into the rolling friction between pipeline 20 and gyro wheel 200 to can reduce the frictional resistance that pipeline 20 received, so set up, can reduce and even avoid the pipe wall attenuation that pipeline 20 and ground contacted, can prolong the life of pipeline 20 relatively.

In addition, in the drag reducing device, the base 100 includes the blocking portions arranged oppositely, the blocking portions protrude from the roller 200 along the radial direction of the roller, after the pipeline 20 is placed on the roller 200, in the process of pulling the pipeline 20, the pipeline 20 is restrained by the blocking portions arranged oppositely, and the deviation cannot occur, that is, the pipeline cannot be easily separated from the roller 200.

In this embodiment, the resting surface is a flat surface, so that the bracket 10 can be stably placed on the ground without easily falling down when the pipe 20 is pulled.

In this embodiment, as shown in fig. 1 or 2, the number of the brackets 10 is plural, and the plural brackets 10 are arranged along the extending direction of the pipe 20.

In the conventional technology, when an electric power pipeline or a gas pipeline is laid, the length of the pipeline 20 is long, so that the arrangement of one bracket 10 cannot meet the actual use requirement, and therefore, a plurality of brackets 10 need to be arranged.

Specifically, the base 100 includes a supporting plate 110, a first blocking plate 120 and a second blocking plate 130 both connected to the supporting plate 110; the roller 200 is pivoted between the first baffle 120 and the second baffle 130; the upper end surfaces of the first barrier 120 and the second barrier 130 protrude from the roller 200.

Illustratively, as shown in fig. 3, the first baffle 120 and the second baffle 130 may both be planar plates. Alternatively, the first baffle 120 and the second baffle 130 are both arc-shaped plates, and are configured to be suitable for the pipeline 20 with bends. For example, at the turn of the pipe 20, the bracket 10 with the first baffle 120 and the second baffle 130 both being arc-shaped plates can be arranged so as to receive the pipe 20 and increase the adaptability of the bracket 10.

In one embodiment of the present application, as shown in fig. 3, the roller 200 includes a roller body 210 and an axle 220 disposed at two ends of the roller body 210; the first baffle 120 and the second baffle 130 are both provided with shaft holes for the axle 220 to pass through.

Wherein, the wheel body 210 and the wheel axle 220 can be integrally arranged; or, the wheel body 210 and the wheel shaft 220 are separately arranged, specifically, a central through hole may be opened at the center of the wheel body 210, the wheel shaft 220 penetrates through the central through hole of the wheel body 210, and the two ends of the wheel shaft 220 are respectively inserted into the first baffle 120 and the second baffle 130, so that the wheel body 210 does not separate from the wheel shaft 220 on the premise of ensuring the rotation of the wheel body 210, and the wheel body 210 and the wheel shaft 220 are more convenient to detach and mount.

Illustratively, the diameter of the axle 220 is phi 25mm and the diameter of the roller 200 is phi 90mm, wherein the roller 200 is a galvanized steel pipe roller.

Further, the axle 220 is in clearance fit with the axle hole; or, a bearing is fixedly arranged at the shaft hole, and the inner ring of the bearing is fixedly connected with the wheel shaft 220. The foregoing arrangements both enable the connection of the axle 220 with the first baffle 120 and the second baffle 130.

As shown in fig. 3, one end of the axle 220 may be provided with a threaded section, locked by a nut; the other end of the axle 220 may be provided with a plurality of threaded holes for engaging pins so that the axle 220 can be fixed in position after the position adjustment of the first shutter 120 mentioned later to prevent the axle 220 from moving in its axial direction to adversely affect the conveyance of the pipe 20. As shown in fig. 2, the supporting plate 110 is provided with a fixing hole 111, and a connecting member (not shown in the drawings) is inserted between the fixing hole 111 and the ground to connect the supporting plate 110 to the ground.

The mode of setting up fixed orifices 111, among them, the ground that is more suitable for at uneven or weak geology pulls pipeline 20, so set up, can not produce the upset because of the skew at bracket 10 when pulling pipeline 20.

In some embodiments, the supporting plate 110 is an "i" shaped frame structure, and the first baffle 120 and the second baffle 130 are respectively disposed at the lateral edge sections of the "i" shaped frame structure; alternatively, the support plate 110 adopts a "triangular" frame structure to improve the stability of the support plate 110 placed on the ground. Alternatively, the support plate 110 has a rectangular plate-shaped structure having a certain thickness.

Illustratively, the supporting plate 110 is a rectangular plate-shaped structure, two fixing holes 111 are formed at two ends of the rectangular plate-shaped structure, the diameter of each fixing hole 111 is phi 20mm, and phi 20 twisted steel bars can be driven into the ground through the fixing holes 111 for fixing during construction.

In some embodiments, the distance between the first baffle 120 and the second baffle 130 is fixed.

In this embodiment, the distance between the first baffle 120 and the second baffle 130 is adjustable to adapt to pipes 20 with different pipe diameters.

In the general technology, during the construction of the power pipeline or the gas pipeline, pipelines 20 with different pipe diameters are involved. Therefore, by adjusting the distance between the first baffle 120 and the second baffle 130, the pipe diameter of the pipe 20 can be appropriately adjusted. In short, when the pipe diameter of the pipe is larger, the distance between the first baffle and the second baffle 130 can be increased, and at this time, even if the length of the roller 200 is smaller than the diameter of the pipe 20, the roller 200 can support the pipe 20; conversely, when the pipe diameter of the pipe is small, the distance between the first baffle and the second baffle 130 can be appropriately reduced.

In order to facilitate the adjustment of the distance between the first barrier 120 and the second barrier 130, in this embodiment, the length of the axle 220 may be increased appropriately to ensure that the bracket 10 cannot be mounted when the distance between the first barrier 120 and the second barrier 130 is changed.

In the present embodiment, the position of at least one of the first shutter 120 and the second shutter 130 on the support plate 110 is adjustable.

For example, the position of the first shutter 120 on the support plate 110 is adjustable; alternatively, the positions of the two second baffles 130 on the supporting plate 110 are adjustable; alternatively, the positions of the first shutter 120 and the second shutter 130 on the support plate 110 may be adjustable.

The present embodiment takes a form in which the position of the first shutter 120 on the support plate 110 is adjustable. In one embodiment of the present application, as shown in fig. 4, the supporting plate 110 is provided with a sliding slot 112, and the bottom width in the sliding slot 112 is greater than the opening width; a slide block (not shown in the figure) which is in sliding fit with the sliding groove 112 is arranged along the length direction; the first baffle 120 is fixedly connected with the sliding block; a locking structure is arranged between the sliding block and the supporting plate 110, and is used for fixing the sliding block to the supporting plate 110.

Referring to fig. 4, when it is required to move the first shutter 120, the first shutter 120 can slide leftwards, and the sliding will drive the first shutter 120 to slide leftwards, so as to increase the distance between the first shutter 120 and the second shutter 130, and vice versa, the distance between the first shutter 120 and the second shutter can be decreased.

Referring to fig. 4, in an embodiment of the present application, the locking structure includes a long circular hole 113 disposed on one side of the support plate 110, a plurality of first circular holes 114 disposed on the other side of the support plate, a second circular hole (not shown in the drawings) disposed on the slider, and a limit pin (not shown in the drawings), wherein the long circular hole 113 and the first circular holes 114 are disposed to penetrate the sliding slot 112. Specifically, after the position of the slider is adjusted, the pin shaft can be sequentially inserted into the oblong hole 113 on one side, the second round hole on the slider, and the first round hole 114 on the other side, so that the slider can be relatively fixed at a certain position. Meanwhile, the position of the first baffle 120 can be conveniently adjusted, and time is saved.

As shown in fig. 4, the plurality of first circular holes 114 are provided along the extending direction of the oblong holes 113, and the oblong holes 113, the first circular holes 114, and the second circular holes are provided at the same height.

The present embodiment also provides a pipelaying apparatus comprising a tractor (not shown in the drawings) and the aforementioned fairing; the tractor is used for being fixedly connected with the pipeline. The pipeline laying equipment provided by the embodiment comprises the damping device, so that the technical advantages and effects achieved by the pipeline laying equipment also comprise the technical advantages and effects achieved by the damping device, and the details are not repeated here.

Because the friction resistance between the brackets 10 between the pipelines can be reduced by the damping device, when the tractor is started to draw the pipeline 20, the running power consumption load of the tractor can be relatively reduced, the drawing construction speed can be accelerated, and meanwhile, the pipeline 20 is also protected, and the material loss of the pipeline 20 is reduced.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not depart from the spirit and scope of the present invention.
