Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of building construction, concretely to pipeline backfill soil compaction degree real -time monitoring devices. BACKGROUND

[0002] Pipeline backfill soil refers to the soil used to fill the space around and above the pipeline after pipeline laying, to prevent mechanical damage to the pipeline from the outside, such as ground vehicle driving, excavation work, etc. At the same time, it reduces the expansion and deformation of the pipeline due to temperature changes and other factors, plays a role in fixing the position of the pipeline, and makes the soil around the pipeline form a stable support structure to bear the weight of the pipeline itself and possible loads above, avoiding sinking, displacement, etc. of the pipeline, ensuring the normal operation of the pipeline system. Good backfill soil can fill the gap between the pipeline and the surrounding soil, reduce the penetration of groundwater or other liquids through these gaps to the surrounding pipeline, and thus prevent the pipeline from being corroded due to long-term immersion in water, and also avoid the leakage of the medium in the pipeline to the surrounding environment.

[0003] The existing pipeline backfill soil compaction degree is detected point by point on the ground using a compaction degree detector. This detection method is inefficient, requires a large amount of manpower and time, and the traditional detection method cannot guarantee continuous and uniform test points, reducing the practicability.

[0009] By the above technical scheme, when the transmission cylinder drives the transmission gear to rotate, the guide gear is synchronously rotated; since the guide gear is designed with missing teeth, the meshing state between the guide gear and the tooth block on the lower surface of the linkage tooth plate periodically changes during the rotation.

[0013] By the above technical scheme, the detection pressing plates are directly in contact with the backfill soil, the arc-shaped design of the two ends of the detection pressing plates can better fit the ground, so that the error caused by uneven ground during detection is reduced, and the accuracy of the detection result is ensured.

[0014] Preferably, the telescopic cylinder is slidingly connected with the support frame, and the upper end of the telescopic cylinder is rotationally connected with the lower end of the pressing link.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-6 This utility model provides a technical solution: a real-time monitoring device for the compaction degree of pipeline backfill soil, including a support frame 1, drive rollers 2, a drive motor 3, a transmission cylinder 4, a transmission gear 5, a linkage gear 6, a guide gear 7, a linkage toothed plate 8, a support slider 9, a limit baffle 10, a downward pressing rod 11, a telescopic cylinder 12, an installation baffle 13, a positioning sliding column 14, and a detection pressure plate 15. The support frame 1 has drive rollers 2 mounted on its surface, and a drive motor 3 is embedded in the side surface of the support frame 1. The output end of the drive motor 3 is fixedly connected to the transmission cylinder 4. The support frame 1 and the drive rollers 2 form a rotatable connection, and the transmission cylinder 4 and the support frame 1 form a rotatable connection. The transmission gear 5 and the linkage gear 6 are connected and meshed. When the drive motor 3 is started, its output end drives the transmission cylinder 4 to rotate. The transmission gear 5 at one end of the transmission cylinder 4 meshes with the linkage gear 6 on the shaft of the drive motor 3 to transmit power. The guide gear 7 on the transmission cylinder 4 rotates synchronously. Because it is coaxial with the transmission gear 5, the guide gear 7 meshes with the lower surface tooth block of the linkage tooth plate 8 installed on the side surface opening of the support frame 1 through the toothed design of the guide gear 7. When the guide gear 7 rotates, it drives the linkage tooth plate 8 to slide on the support frame 1. The support slider 9 at one end of the linkage tooth plate 8 slides synchronously on the support frame 1 to ensure the stable movement of the linkage tooth plate 8.

[0030] A transmission gear 5 is fixedly connected to one end of the transmission cylinder 4. A linkage gear 6 is fixedly connected to the surface of the shaft of the drive motor 3. A guide gear 7 is fixedly connected to the surface of the transmission cylinder 4. An opening is provided on the side surface of the support frame 1, and a linkage gear plate 8 is installed in the opening on the side surface of the support frame 1. The guide gear 7 is coaxial with the transmission gear 5 and has a missing tooth design. The linkage gear plate 8 is slidably connected to the support frame 1, and a tooth block is provided on the lower surface of the linkage gear plate 8. The linkage gear plate 8 connects with the guide gear 7 through the tooth block. The support slider 9 and the support frame 1 are connected in an interlocking manner. A spring is connected between the limiting baffle 10 and the support frame 1. The pressing link 11 and the limiting baffle 10 are connected in a rotating manner. The limiting baffle 10, which is fixed on the outer surface of the support slider 9, moves with the linkage tooth plate 8. The spring connected between the limiting baffle 10 and the support frame 1 plays a buffering and resetting role. The pressing link 11, which is connected to the outer surface of one end of the limiting baffle 10, can flexibly adjust its angle during the pressing process because it is connected in a rotating manner with the limiting baffle 10.

[0031] One end of the linkage toothed plate 8 is fixedly connected to a support slider 9. A limit baffle 10 is fixedly connected to the outer surface of the support slider 9. A pressing rod 11 is connected to the outer surface of one end of the limit baffle 10. The detection mechanism includes a telescopic cylinder 12. The telescopic cylinder 12 is installed on the inner wall of the opening on the lower surface of the support frame 1. An installation baffle 13 is fixedly connected to the lower surface of the telescopic cylinder 12. An opening is provided on the surface of the installation baffle 13, and a positioning slide column 14 is installed on the inner wall of the opening of the installation baffle 13. A detection pressure plate 15 is fixedly connected to the lower surface of the two positioning slide columns 14. The pressing rod 11 pushes the telescopic cylinder 12 down. The telescopic cylinder 12 is slidably connected to the support frame 1, and its upper end is rotatably connected to the lower end of the pressing rod 11 to ensure stable pressing. The installation baffle 13 fixed on the lower surface of the telescopic cylinder 12 also descends. The installation baffle 13 drives the positioning slide column 14 to descend as well. The detection pressure plate 15 fixed on the lower surface of the positioning slide column 14 then contacts the ground.

[0032] The lower surface of the support frame 1 has an opening, and a detection mechanism is installed on the inner wall of the opening. This mechanism, via a downward pressing rod 11, pushes the telescopic cylinder 12 and the mounting baffle 13 downwards, facilitating the lifting of the detection plate 15 by the ground and causing the positioning slide column 14 to slide upwards. The telescopic cylinder 12 is slidably connected to the support frame 1, and its upper end is rotatably connected to the lower end of the downward pressing rod 11. The mounting baffle 13 is slidably connected to the positioning slide column 14, and a spring connects the mounting baffle 13 and the positioning slide column 14. The two ends of the detection plate 15 are arc-shaped. After the detection plate 15 contacts the ground, different ground compaction levels result in different reaction forces on the detection plate 15. The reaction force on plate 15 causes the positioning slide column 14 to slide upward within the mounting baffle 13. The mounting baffle 13 and the positioning slide column 14 form a sliding connection and are connected by a spring. The spring plays a buffering and stabilizing role, so that the sliding distance of the positioning slide column 14 can reflect the compaction degree of the backfill soil. When the missing tooth part of the guide gear 7 rotates to the position opposite to the linkage tooth plate 8, the linkage tooth plate 8 resets under the action of the spring, driving the lowering connecting rod 11, telescopic cylinder 12, mounting baffle 13, positioning slide column 14 and detection pressure plate 15 to rise and reset, completing one detection cycle. The device moves to the next detection point under the action of the drive roller 2 and repeats the above detection process to realize real-time monitoring of the compaction degree of pipeline backfill soil.

[0033] Working Principle: When using this real-time monitoring device for backfill compaction, the drive motor 3 drives the transmission gear 5 to rotate. The transmission gear 5 drives the linkage gear 6 and the transmission cylinder 4 to rotate, causing the guide gear 7 to rotate synchronously. The guide gear 7 drives the linkage toothed plate 8 to slide on the support frame 1, causing the support slider 9 and the limit baffle 10 to move. This allows the limit baffle 10 to push the downward connecting rod 11, causing the telescopic cylinder 12 and the mounting baffle 13 to descend. The detection pressure plate 15 contacts the ground, and the reaction force on the detection pressure plate 15 causes the positioning slide column 14 to slide within the mounting baffle 13, thus reflecting the compaction degree. When the missing tooth of the guide gear 7 aligns with the linkage toothed plate 8, the linkage toothed plate 8 resets, driving all components to rise, completing one detection cycle. The device repeats this process after moving to a new position, achieving real-time monitoring and increasing overall practicality.
