Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to an anti-leakage device for engineering pipelines. Background Art

[0002] During the pipeline installation process, generally, a preset pit for placing the pipeline is first dug, and then the workers place several pipes in the preset pit in turn, and then align and weld the two adjacent pipes at the head and tail to complete the installation of the pipeline.

[0003] Because soil varies across regions, some areas have looser soil, which can lead to settlement in the pre-set pits for pipe placement. Because the pipes are fixed at their ends, settlement within the pre-set pits can easily cause portions of the pipe's outer walls to become suspended, resulting in uneven stress on the pipes. Over time, these suspended outer walls can crack, leading to leakage. Therefore, a technical solution is needed to address this issue. Utility Model Content

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] Example 1

[0021] See also Figure 1-5 The cam 2 is provided with a plurality of air bags 4 for connecting to the airbag 4, and the air bags 4 are provided with a plurality of air bags 4 for connecting to the airbag 4. 3. Airbag 4, tightening belt 6 and winding-up mechanism. The staff places the base 1 and tightening seat 3 respectively just below and just below the suspended position of the pipeline, and inserts the plug plate 7 of the tightening belt 6 into the slot 8 on the side of the support seat 2 to form a closed loop structure. Then, the tightening belt 6 is tightened by the winding-up mechanism to achieve the fixation of the support seat 2 and the tightening seat 3 on the pipeline. Finally, the one-way inflation pipe mouth 5 on the side of the base 1 is inflated by the air pump. During the process of increasing air pressure inside the airbag 4, the support seat 2 can be driven to slide in the base 1, and the bottom surface of the base 1 is pressed against the preset pit. The support wheel of the support seat 2 on the pipeline and the gravity on the pipeline form a pair of interactive forces, thereby reducing the occurrence of outer wall breakage due to suspension of the pipeline and reducing leakage of the pipeline.

[0022] Wherein, rubber pads are symmetrically provided on the adjacent surfaces of the support seat 2 and the tightening seat 3 .

[0023] In addition, the inner cavity side wall of the base 1 is symmetrically provided with a limiting groove 9, and the bottom of the side of the support seat 2 is fixedly provided with a limiting block 10 that slides with the limiting groove 9. The setting of the limiting block 10 and the limiting groove 9 can limit the maximum stroke of the support seat 2 to prevent the support seat 2 from detaching from the base 1.

[0024] Example 2

[0025] This embodiment describes the winding and unwinding mechanism in detail based on the embodiment 1, specifically:

[0026] See also Figure 4 and Figure 5 The first gear 13 and the second gear 14 are meshed with each other and are used to rotate the two winding rollers 11 relative to each other, and the two winding belts 6 are wound around the winding roller 11.

[0027] In addition, after stopping the rotation of the first knob 15, in order to prevent the reversal of the winding roller and the loosening of the tightening belt 6, the winding mechanism in this embodiment also includes a braking unit for limiting the rotation of the drive shaft 12, and the braking unit includes a hollow disk 16 fixedly mounted on the tightening seat 3, a ratchet 17 rotatably arranged in the hollow disk 16, and a pawl 18 adapted to the ratchet 17, the ratchet 17 is coaxially fixedly connected to the drive shaft 12, and a second knob 19 connected to the pawl 18 is further installed outside the hollow disk 16. In other words, the cooperation between the ratchet 17 and the pawl 18 makes it possible for the drive shaft 12 to drive the two winding rollers in one direction to rewind the tightening belt 6. After the first knob 15 stops rotating, the ratchet 17 and the pawl 18 can limit the reversal of the drive shaft 12, thereby braking the drive shaft 12 and preventing the tightening belt 6 from loosening. In addition, when the second knob 19 on the hollow disk 16 is rotated, the pawl 18 can be driven to separate from the ratchet 17. At this time, the two unwinding rollers 11 can be driven to reverse by rotating the second knob 19.
