[0023] To address the aforementioned problems, this application proposes improvements and innovations, including the following embodiments.

[0024] In one implementation, please refer to Figure 1 , Figure 2 , Figure 3This application provides a pipeline suspension protection device for municipal construction, including a base plate 1, a protective plate 2, positioning rods 3, locking bolts 4, locking nuts 5, hooks 6, wire ropes 7, and lifting rods 8. The base plate 1 is a long, flat plate structure. At least two positioning rods 3 are vertically fixed on both sides of the top of the base plate 1 along its length. The existing pipeline 100 excavated during construction is placed between the two positioning rods 3. The protective plate 2 is fastened and installed above the base plate 1, with corresponding positioning rods on the protective plate 2. The rod 3 has a through hole 21 that passes through the guard plate 2, and each positioning rod 3 can be slidably inserted into the through hole 21; the distance between the guard plate 2 and the bottom plate 1 is adjustable, and the guard plate 2 and the bottom plate 1 are locked by locking bolts 4 that pass through the guard plate 2 and the bottom plate 1 from top to bottom and locking nuts 5. At least two hooks 6 are fixedly installed on both sides of the bottom plate 1 along the length direction, and a steel wire rope 7 is threaded on each hook 6. The steel wire rope 7 is hung on the lifting rod 8, and the lifting rod 8 is erected on the top of the foundation pit.

[0025] Thus, by fixing the positioning rod 3 on the base plate 1, a hollow frame can be formed by the base plate 1 and the positioning rod 3 for the initial stacking of the original pipeline 100, so that the original pipeline 100 can be gathered within the frame. The base plate 1 and the positioning rod 3 can be pre-installed to improve the on-site assembly efficiency of this pipeline suspension protection device.

[0026] By fastening a protective plate 2 above the base plate 1 and locking the base plate 1 and protective plate 2 with locking bolts 4 and locking nuts 5, the original pipeline 100 that needs protection can be gathered and bundled together by the base plate 1, positioning rod 3, protective plate 2, locking bolts 4 and locking nuts 5. The base plate 1 is then suspended by steel wire rope 7 and hanging rod 8 to achieve stable and reliable suspension protection for the original pipeline 100. The structure is simple, easy to assemble and disassemble, saves time and effort, and can effectively prevent damage to the original pipeline 100 during construction. There is no need to cut or modify the original pipeline 100, and it will not affect the normal use of the original pipeline 100, which is conducive to ensuring the progress of the established construction project.

[0027] By opening a through hole 21 on the protective plate 2, the distance between the protective plate 2 and the base plate 1 can be adjusted by the cooperation of the positioning rod 3 and the through hole 21. After the original pipeline 100 is stacked, the protective plate 2 and the base plate 1 are locked with locking bolts 4 and locking nuts 5. This allows for adaptive adjustment of the distance between the protective plate 2 and the base plate 1 according to the condition of the original pipeline 100 on site, thereby meeting the suspension protection requirements for different numbers and diameters of the original pipeline 100.

[0028] In this embodiment, the minimum spacing between the positioning rods 3 on both sides of the base plate 1 along its length and the minimum spacing between the locking bolts 4 along the width of the base plate 1 is less than the minimum spacing between the locking bolts 4 along the width of the base plate 1. Thus, during the initial stacking of the original pipeline 100 when installing this pipeline suspension protection device, the positioning rods 3 can limit the movement of the dispersed original pipeline 100, preventing it from spreading out and interfering with the subsequent installation of components such as the protective plate 2, locking bolts 4, and buffer spring 10. This improves the stability of the pipeline suspension protection device and increases construction efficiency.

[0029] Specifically, during the excavation of the foundation pit, when the original pipeline 100 is exposed inside the pit after the pit is excavated downwards and needs to be protected, the hoist 8 is first erected at the top of the foundation pit, and the original pipeline 100 is gathered and stacked within the frame composed of the base plate 1 and the positioning rod 3. Then, the length of the wire rope 7 is adjusted to adjust the suspension height of the base plate 1 so that the original pipeline 100 is as close as possible to the original installation height or slightly higher than the original installation height, so as to avoid the original pipeline 100 being in a suspended state and deforming or bursting. Then, the protective plate 2 and locking bolts 4 and locking nuts 5 are installed to bind and reinforce the original pipeline 100, thereby gathering and binding the original pipeline 100 that needs to be protected together, thus completing the suspension protection of the original pipeline 100 in the foundation pit.

[0030] In some embodiments, a spring retaining sleeve 9 is fixedly installed at the top of the base plate 1 and the bottom of the guard plate 2 at the position corresponding to the locking bolt 4. The inner wall of the spring retaining sleeve 9 is spaced apart from the locking bolt 4. The two spring retaining sleeves 9 located at both ends of the same locking bolt 4 are coaxially arranged with the locking bolt 4, and the opposite ends of the two spring retaining sleeves 9 are constructed with receiving grooves 91 extending along the axial direction of the spring retaining sleeve 9. A buffer spring 10 is respectively arranged between the two spring retaining sleeves 9 located at both ends of the same locking bolt 4, and the two ends of the buffer spring 10 are respectively arranged in the receiving grooves 91 of the two spring retaining sleeves 9.

[0031] Therefore, if a buffer spring 10 is not provided between the protective plate 2 and the base plate 1, when the protective plate 2 is installed, it will directly press against the original pipeline 100 after being inserted from the positioning rod 3. This makes it easy to overtighten the locking nut 5 when installing the locking bolt 4 and locking nut 5, thus posing a risk of damage to the original pipeline 100 due to excessive clamping between the protective plate 2 and the base plate 1. Therefore, in this embodiment, by providing a buffer spring 10 between the protective plate 2 and the base plate 1 corresponding to the locking bolt 4, the installation... During the process of tightening the guard plate 2, the buffer spring 10 can buffer the guard plate 2, so that there is enough space for rebound and tightening between the guard plate 2 and the base plate 1. Thus, during the tightening of the locking nut 5, the installation position of the guard plate 2 can be adaptively adjusted according to the height of the original pipeline 100 initially stacked in the frame of the base plate 1 and the positioning rod 3. In this way, the original pipeline 100 can be reliably gathered and bundled while avoiding damage to the original pipeline 100 due to over-tightening of the locking nut 5.

[0032] In some embodiments, the lower end of the buffer spring 10 is fixedly disposed within the receiving groove 91 of the spring fixing sleeve 9 located at the top of the base plate 1, and the upper end of the buffer spring 10 is movably inserted into the receiving groove 91 of the spring fixing sleeve 9 located at the bottom of the protective plate 2. Thus, by pre-fixing the lower end of the buffer spring 10 within the receiving groove 91 of the spring fixing sleeve 9 located at the top of the base plate 1, the buffer spring 10 and the base plate 1 can be pre-installed, thereby facilitating improved on-site assembly efficiency of this pipeline suspension protection device.

[0033] In one alternative embodiment, the projection of the positioning rod 3 onto the plane of the base plate 1 is rectangular, and the extension direction of the long side of this rectangle is consistent with the extension direction of the original pipeline 100. This increases the contact area between the positioning rod 3 and the original pipeline 100, which is beneficial to improving the stacking stability of the original pipeline 100. The top of the positioning rod 3 is chamfered; this facilitates the quick insertion of the protective plate 2 into each positioning rod 3 during installation, thereby improving installation efficiency.

[0034] In some embodiments, the locking nut 5 is fixedly installed at the bottom of the base plate 1 corresponding to the position of the locking bolt 4. The locking bolt 4 passes through the guard plate 2 and the base plate 1 from top to bottom and engages with the locking nut 5. Thus, by pre-fixing the locking nut 5 to the bottom of the base plate 1 by welding or other means, when installing the locking bolt 4, the locking bolt 4 passes through the guard plate 2 and the base plate 1 from top to bottom and engages with the locking nut 5. Then, the locking bolt 4 is rotated to the appropriate position. In this way, by using the method of installing the locking bolt 4 from top to bottom and by pre-fixing the locking nut 5, the locking bolt 4 and the locking nut 5 can be prevented from falling off during installation and disassembly, thereby improving the convenience and efficiency of disassembly and assembly.

[0035] In some embodiments, the protective plate 2 has an upwardly recessed center with a positioning groove 22 extending through the protective plate 2 along its length. The cross-sectional shape of the protective plate 2 at the positioning groove 22 is arc-shaped. Thus, when the number of existing pipelines 100 that need protection cannot be stacked in a rectangular manner within the frame formed by the base plate 1 and the positioning rod 3, the positioning groove 22 can provide a space for the excess existing pipelines 100, thereby effectively improving the compatibility between the binding space formed by the base plate 1, the protective plate 2, and the positioning rod 3 and the existing pipelines 100, and effectively improving the binding stability of the existing pipelines 100.

[0036] In some embodiments, the width of the guard plate 2 is no greater than the width of the base plate 1. In this way, when the base plate 1 is suspended by the wire rope 7 and the hanger 8, the guard plate 2 can avoid interfering with the wire rope 7.

[0037] Finally, it should be noted that although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, all of which should be included within the protection scope of this application.
