DETAILED DESCRIPTION

[0022] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0023] like Figure 1 and Figure 2 As shown, the embodiment of the utility model provides a pipeline laying device for road construction, comprising:

[0024] Two support frames 1 arranged in mirror image;

[0025] The support rod 3 is slidably disposed between the two support frames 1 and has a track groove 14 along its length direction;

[0026] Two tie rods 8 arranged in mirror image, with a bearing plate 9 for supporting the pipeline provided at one end of the tie rod 8 and a moving plate 10 provided at the other end, the moving plate 10 provided with a pulley 13, the pulley 13 being mounted on a track groove 14, and the moving plate 10 further provided with a clamp connected to the tie rod 8, when the tie rod 8 is forced to drop, the clamp is clamped on the support rod 3 to fix the moving plate 10; and

[0027] The lifting assembly is connected to the support rod 3 and is used to control the lifting of the support rod 3.

[0028] In the embodiment of the utility model, the two support frames 1 are arranged in a mirror image, and the support rod 3 can be suspended. During the installation of the pipeline, the support frame 1 can be directly erected on both sides of the groove, and the axis of the pipeline is parallel to the axis of the support rod 3. When the pipeline is transported, the two pull rods 8 are directly moved away from each other. When the pipeline is located between the two pull rods 8, the two pull rods 8 are pushed respectively to abut against the end of the pipeline, so that the bearing plate 9 at the end of the pull rod 8 is placed on the inner wall of the pipeline. The height of the support rod 3 is increased by the cooperation of the lifting assembly, so that the pipeline can be supported and lifted by the bearing plate 9 on the pull rod 8, thereby separating the pipeline from the ground.

[0029] After the pipeline is transported to the designated trench through the cooperation of the two support frames 1 and the support rod 3, the pipeline can be placed in the trench by lowering the support rod 3. When the pipeline is stable, the support rod 3 is lowered again to separate the load-bearing plate 9 from the inside of the pipeline, and the pull rod 8 is directly pushed to slide in the track groove 14 under the action of the moving plate 10 and the pulley 13, so that the load-bearing plate 9 is out of the inner wall of the pipeline, and the installation of the pipeline can be released. Compared with the traditional rope fixing method, the use of the pull rod 8 and the load-bearing plate 9 can ensure the stability of pipeline lifting and transportation. Moreover, only the pull rod 8 needs to be pushed to combine or separate the load-bearing plate 9 from the pipeline, which is convenient for construction operations and saves time and manpower.

[0030] At the same time, when the pull rod 8 is affected by the gravity of the pipeline and causes the pull rod 8 to drive the clamp to descend, the clamp can be directly clamped into the support rod 3, completing the position limitation of the pull rod 8, ensuring that the movable plate 10 will not move during the installation of the pipeline, thereby ensuring stability.

[0031] Specifically, Figure 3 As shown, the clamping member includes a movable plate 11 which is slidably clamped on the movable plate 10 and fixedly connected to the pull rod 8. The movable plate 11 is provided with a clamping block 12. The support rod 3 is provided with a plurality of clamping grooves 301 corresponding to the clamping block 12. The movable plate 11 is also provided with a connecting rod 16. The connecting rod 16 is penetrated by the movable plate 10, and the connecting rod 16 is sleeved with a spring 17. The spring 17 abuts between the movable plate 10 and the movable plate 11. When the clamping member is working, that is, when the load-bearing plate 9 is subjected to the gravity of the pipeline, the gravity is transmitted to the pull rod 8, so that the pull rod 8 drives the movable plate 11 to descend on the movable plate 10, and the spring 17 is compressed. At this time, the clamping block 12 on the movable plate 11 is directly clamped to the corresponding clamping block 12. In the groove 301, the movable plate 10 cannot move even when the active plate 11 cannot move. When the pipeline is installed, the supporting plate 9 is lowered and separated from the inner wall of the pipeline, so that the supporting plate 9 will not be affected by the force brought by the pipeline, so that the movable plate 11 is reset and rises under the action of the spring 17 (the spring 17 can withstand the pressure of the pull rod, the supporting plate 9 and the movable plate 11), so that the block 12 of the movable plate 11 is separated from the slot 301, and the movable plate 11 becomes movable again under the action of the pulley 13, which makes it convenient to remove the supporting plate 9, and there is no need to manually adjust and fix the pull rod 8, which is more convenient to operate and has a simple structure.

[0032] Based on the above scheme, if Figure 1As shown, the lifting assembly includes two reel wheels 5 respectively rotatably arranged on two support frames 1 and a suspension rope 4 wound around the reel wheels 5, the two reel wheels 5 are connected by a transmission rod 18, the suspension rope 4 is connected to the support rod 3, one of the support frames 1 is provided with a driver 6, and the output shaft of the driver 6 is connected to one of the reel wheels 5; when the support rod 3 is lifted and lowered by the lifting assembly, the driver 6 is started so that the driver 6 drives the two reel wheels 5 to rotate synchronously to retract and release the suspension rope 4, so that the support rod 3 can be quickly raised or lowered between the two support frames 1, which is convenient for adjustment. The driver 6 is a motor or an electric motor.

[0033] Specifically, Figure 1 As shown, the inner mirror image of the support frame 1 is provided with two limit plates 7, and the support rod 3 is slidably arranged between the two limit plates 7; under the action of the limit plates 7, the support rod 3 can be prevented from swinging in the radial direction of the pipeline to ensure stability, and the limit plates 7 are provided with a slide groove 701, and a slider is provided at the end of the support rod 3. The limit plate 7 is slidably engaged in the slide groove 701 through the slider, so that one end of the support rod 3 can only be located between the two limit plates 7 at all times, further ensuring the stability of the pipeline construction and preventing swinging.

[0034] Specifically, Figure 1 As shown, a moving wheel 2 is provided at the bottom of the support frame 1. With the action of the moving wheel 2, the support frame 1 can be conveniently moved, two support frames 1 can be conveniently erected on the groove, and can work continuously, thereby improving work efficiency.

[0035] Specifically, Figure 1 As shown, the bearing plate 9 is in an arc-shaped structure, so that the shape of the bearing plate 9 is more closely fitted to the inner wall of the pipe, thereby increasing the contact area between the bearing plate 9 and the inner wall of the pipe.

[0036] In summary, the present invention transports the pipeline by the action of the pull rod 8 and the supporting plate 9, thereby ensuring stability, so that the pipeline will not swing during transportation and installation, and the positions of the two pull rods 8 can be flexibly adjusted, so that pipelines of different lengths can be installed. After the pipeline is installed by the supporting plate 9, the supporting plate 9 transmits the gravity of the pipeline to the movable plate 11, so that the block 12 on the movable plate 11 is directly connected to the corresponding slot 301, and the movable plate 11 is automatically moved to a certain point on the support rod 3 without manual intervention. After the pipeline is released from installation, the movable plate 11 is returned by the spring 17, so that the block 12 is separated from the slot 301, and the limit of the movable plate 11 is quickly released, which makes it convenient to separate the supporting plate 9 from the pipeline, and no manual intervention is required. The operation is simpler and less difficult.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
