Its construction quality has a great impact on the quality of life of urban residents. Pipeline laying is a time-consuming and labor-intensive project. Pipelines are connected and laid to achieve the purpose of connecting all pipelines.

[0003] Traditionally, heating and cooling pipelines are laid using direct burial excavation or pipe jacking technology. However, during the construction process, the pipelines are subject to wear and mechanical damage, which poses certain safety hazards and has a serious impact on the safe operation of the equipment.

[0004] Therefore, direct lifting is now used to lay pipelines. However, due to the large size of some pipelines, multiple construction workers are required to cooperate in the operation, and lifting equipment is needed to lift the pipeline to a predetermined position in a predetermined pit. When each pipeline is laid, it is necessary to repeatedly lift, lay, and connect. In this process, not only do the construction workers need to repeatedly dock and adjust, but the operators of the lifting equipment also need to repeatedly operate, resulting in low construction efficiency. Therefore, it is necessary to design a pipeline laying device to improve the efficiency, safety, and reliability of pipeline laying. Utility Model Content

DETAILED DESCRIPTION

[0022] The present invention is further described in detail below in conjunction with specific embodiments, but the implementation methods of the present invention are not limited thereto.

[0023] See also Figure 1 to Figure 5 The utility model provides a pipeline laying device, which specifically includes two supporting plates 1 arranged opposite to each other, wherein the lower end surface of the supporting plate 1 is provided with several groups of rolling mechanisms 2, and the inner side is provided with a limit plate 3 fixed downward, wherein the rolling mechanism 2 is located on both sides of the pipeline laying pit, and the limit plate 3 is located in the pipeline laying pit; a rigid support plate 4 and a flexible support belt 5 are respectively arranged between the supporting plates 1, and the two ends of the pipeline to be laid are respectively located on the rigid support plate 4 and the flexible support belt 5, and the flexible support belt 5 is pressed to drive the pipeline to be laid to tilt downward. Preferably, the rolling mechanism 2 is a roller, and the pipeline to be laid is placed on the rigid support plate 4 and the flexible support plate, and then the roller drives the whole device forward, and the limit plate 3 is used to limit the movement direction of the whole laying device, and finally the pipeline is transported to the installation position, and the pipeline to be laid can be quickly placed in the pit through one end of the flexible support belt 5, which is convenient and fast, and can save economic costs.

[0024] The two ends of the rigid support plate 4 are fixed to the inner side of the support plate 1 through a mounting block 6. The mounting block 6 has a cavity inside. A limit rod 7 is vertically mounted in the cavity. A spring 8 is mounted on the limit rod 7. The two ends of the rigid support plate 4 are connected to the limit rod 7 through a connecting plate 9 movably mounted on the limit rod 7. The connecting plate 9 can move up and down in the mounting block 6 along the limit rod 7. At the same time, the lower end of the spring 8 is connected to the bottom of the mounting block 6, and the upper end is connected to the lower end surface of the connecting plate 9, to ensure that when the pipeline is located on the rigid support plate 4, the spring 8 is compressed to provide more effective support for the pipeline to be laid.

[0025] Preferably, the rigid supporting plate 4 is arc-shaped, and the arc-shaped supporting plate can better limit the position of the pipeline to be laid during the movement of the laying device to prevent it from rolling off the laying device.

[0026] Furthermore, a belt groove 10 is fixed on the inner side of the support plate 1, and the belt groove 10 has a slot that passes through from top to bottom, and a connecting belt 11 is installed in the slot. The lower end of the connecting belt 11 extends out of the slot and is connected to a counterweight block 12, and the upper end extends out of the slot and is connected to a flexible supporting belt 5. The weight of the counterweight block 12 is less than the force applied by the pipeline to the flexible supporting belt 5. By adjusting the weight of the counterweight block 12, pipes of different weights are placed on the laying device and are all in a certain tilted state.

[0027] The rigid support plate 4 and the flexible support belt 5 are respectively arranged at the two ends of the support plate 1, and the two end pipe openings of the pipeline to be laid are respectively placed on the rigid support plate 4 and the flexible support belt 5. At this time, the flexible support belt 5 is pressed to drive the pipeline to tilt downward, and the pipeline in this state is moved to the position to be laid through the laying device, and then the inclined end of the pipeline is fixed, and the laying device is retreated, so that the pipeline is separated from the laying device, and then falls smoothly into the pit, and the position of the pipeline is fine-tuned so that it can be smoothly welded with the pipe opening to be connected.

[0028] In actual use, since the pipeline is long, multiple laying devices can be set up to jointly support the pipeline. It is only necessary to place the ends of the pipeline on the rigid supporting plate 4 and the flexible supporting belt 5 respectively.

[0029] In addition, due to the different diameters of the pipelines, it is difficult to place the pipelines with larger diameters directly on the rigid support plate 4 and the flexible support belt 5 by means of lifting equipment. Therefore, the pipeline is lifted onto the support plate 1 and then pushed and rolled into the rigid support plate 4 and the flexible support belt 5. A flap 13 is installed in the middle of the support plate 1 by rotating through a rotating shaft. The flap 13 can be flipped 180° along the upper end of the support plate 1 and can be fixed in the vertical direction. The flap 13 is used as a part of the support plate 1. When the flap 13 is flipped outward 180° to be parallel to the support plate 1, the supporting area for the pipeline is larger. When placing a pipe with a larger diameter, the lifting equipment can quickly and accurately place the pipe on the support plate 1. After the pipe is placed in the rigid support plate 4 and the flexible support belt 5, the flap 13 can be flipped upward to a vertical state, and the pin can be inserted into the pin hole in the support plate 1 to fix the flap 13, so that the pipe can be positioned to prevent it from rolling off the side of the support plate 1. In addition, the outer end face of the flap 13 is an inclined surface. When the lifting equipment accidentally places the pipe on the edge of the flap 13, the inclined surface can be used to directly push the pipe to roll onto the support plate 1, and then roll onto the rigid support plate 4 and the flexible support belt 5, thereby improving work efficiency.

[0030] In addition, the two limit plates 3 on the two support plates 1 are connected by a traction end 14, and the front and rear ends of the traction end 14 have traction rings 15. The laying device equipped with the pipeline is moved to the installation position through the traction ring 15 at the front end of the traction end 14, and the traction ring 15 at the rear end is dragged to separate the laying device from the pipeline.

[0031] The specific use process of the pipeline laying device is as follows:

[0032] When laying the pipeline, first place the laying device in the pipeline pit, then use the lifting equipment to guide the pipeline to be laid onto the rigid support plate 4 and the flexible support belt 5. At this time, the flexible support belt 5 is pressed to drive the pipeline to tilt downward, and then connect it with the traction ring 15 through the traction equipment, drag the laying device to move to the pipeline to be installed. After moving to the position to be laid, fix one end of the pipeline tilting, and move the laying device backward, so that the pipeline to be laid is separated from the laying device, so that it falls smoothly into the pit, and then only needs to fine-tune the position of the pipeline to be smoothly welded with the pipe mouth to be docked. When the pipeline is safely completed, the construction worker can connect it with the traction ring 15 through the traction equipment, drag the entire laying device to move the next pipeline to be installed, so as to carry out more efficient laying and installation.

[0033] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
