Description

Technical Field

[0001] The utility model relates to the technical field of pipeline transport vehicles, in particular to a semitrailer used for transporting large-diameter pipelines. Background Art

[0002] A pipeline refers to a device connected by pipes, pipe connectors and valves for conveying gas, liquid or fluid with solid particles. Pipes are classified into metal pipes and non-metallic pipes according to the material. The outer diameter of the pipeline varies. For example, the outer diameter of the municipal drainage pipeline is usually above 1500mm. When transporting such pipelines, they are transported by semi-trailers. Such pipelines are all round. If they are placed directly on the semi-trailer, the pipeline will shake on the semi-trailer when braking, turning or encountering bumpy roads. In the prior art, the pipeline is usually fixed by pads or binding, but it is still dangerous when encountering sudden braking and is prone to shaking. After searching, many devices for fixing small-diameter pipelines were found, but these devices are not suitable for fixing large-scale pipelines, and no devices for fixing large-size pipelines were found during the search. Utility Model Content

[0003] The utility model aims to solve the shortcomings in the prior art and proposes a semi-trailer for transporting pipelines.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] A semi-trailer for transporting pipelines comprises a vehicle body, a pipeline fixing device fixedly connected to the upper side of the vehicle body, the pipeline fixing device comprising a bottom plate, a pad plate detachably fixedly connected to the upper side of the bottom plate, the upper surface of the pad plate is an inwardly concave arc surface, a plurality of groups of limit devices are arranged on both sides of the pad plate, each limit device comprises two limit blocks, the limit blocks are detachably fixed to the bottom plate, the limit blocks are provided with arc surfaces, an arc pressure plate is hinged on the upper side of the limit blocks, and the two opposite arc pressure plates can be detachably fixed together.

[0006] Preferably, the first pull rods are detachably fixedly connected between the limit blocks.

[0007] Preferably, one end of each arc-shaped pressing plate is fixedly connected to the connecting plate, and two opposite arc-shaped pressing plates are detachably fixed together via the connecting plate.

[0008] Preferably, one side of the arc-shaped pressure plate is fixedly connected to an "L"-shaped baffle.

[0009] Preferably, the second pull rod is fixedly connected between the two “L”-shaped baffles.

[0010] The advantages of the utility model are: the utility model provides a semi-trailer for transporting pipelines, which rotates the arc-shaped pressure plate so that the inner arc surface of the arc-shaped pressure plate fits with the outer surface of the pipeline, thereby being able to completely fix the pipeline in the radial direction, and the pipeline can be shielded and limited by the "L"-shaped baffle, and the second pull rod passes through the pipeline to enhance the fixing effect, and a second limit is performed from the axial direction of the pipeline, thereby being able to achieve full axial and radial fixation of the pipeline.

[0014] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model. Example

[0015] like Figure 1-3 As shown, the utility model provides a semi-trailer for transporting pipelines, including a vehicle body 1, a pipeline fixing device fixedly connected to the upper side of the vehicle body 1, the pipeline fixing device including a bottom plate 2, a pad 3 detachably fixedly connected to the upper side of the bottom plate 2, the pad 3 detachable manner is the prior art, which will not be described in detail here, the upper surface of the pad 3 is an inwardly concave arc surface, and multiple groups of limit devices are provided on both sides of the pad 3, each of the limit devices includes two limit blocks 4, and the limit blocks 4 are detachably fixedly connected to the first pull rod 8, and the first pull rod 8 can increase the strength of the limit blocks 4 and prevent the limit blocks 4 from being offset. The limit blocks 4 are detachably fixed to the bottom plate 2, and the detachable fixing manner is also the prior art, which will not be described in detail here, and the limit blocks 4 are provided with an arc surface, which can fit tightly with the outer surface of the pipeline. The upper side of the limit block 4 is hinged with an arc-shaped pressing plate 5, one end of each arc-shaped pressing plate 5 is fixedly connected to a connecting plate 7, and two opposite arc-shaped pressing plates 5 are detachably fixed together by the connecting plate 7, and the connecting plate 7 is detachably fixed by bolts.

[0016] When in use, the pipe 100 is first placed on the pad 3, and it is not easy to roll without being subjected to a large external force. At this time, the arc-shaped pressure plate 5 can be rotated so that the inner arc surface of the arc-shaped pressure plate 5 fits with the outer surface of the pipe 100. At this time, the connecting plate 7 is in contact, and the connecting plate 7 can be fixed together by bolts, so that the radial direction of the pipe 100 can be completely fixed. In order to enhance the fixing effect, the pipe 100 is axially limited for a second time, so an "L"-shaped baffle 6 is fixedly connected to one side of the arc-shaped pressure plate 5. The "L"-shaped baffle 6 can block and limit the pipe 100, and a second pull rod is fixedly connected between the two "L"-shaped baffles 6. The second pull rod passes through the pipe 100, so the pipe 100 can be axially fixed. In normal use, the pad 3 and the fixing device can be removed and used as a normal semi-trailer.
