Technical Field

[0001] The utility model relates to the technical field of site flatness detection, in particular to a backfill flatness detection device. Background Art

[0002] During the construction process, trenches are often excavated for laying pipelines. However, after laying, in order to ensure operational safety and the convenience of site use, the trenches must be backfilled and made flat to a certain degree. Backfilling the trenches and making them flat can provide safety guarantees. Unbackfilled or uneven trenches are prone to tripping, falling and other accidents, especially in places where pedestrians and vehicles frequently pass by. By backfilling and making them flat, potential dangers can be eliminated and the risk of injury to personnel and vehicles can be reduced. After the trenches are backfilled, their flatness needs to be tested;

[0003] When the existing technology detects the flatness of the trench after backfilling, workers are usually required to use a handheld level ruler to perform the test, which is time-consuming, cannot meet the detection needs of large-scale construction, and has low detection efficiency.

[0004] In order to solve the above problems, a backfill flatness detection device is proposed in the present application. Utility Model Content

[0021] In this embodiment, a fixed plate 2 is installed at the end of the mobile trolley 1, and a rod-type elastic member 3 is inserted on the fixed plate 2. A rolling member 4 is installed at the bottom of the rod-type elastic member 3, and the rolling member 4 is used to roll on the ground. The rod-type elastic member 3 includes a connecting rod 31 and a first spring 32. A through hole is opened in the fixed plate 2, and the connecting rod 31 slides through the hole. The rolling member 4 is installed at the bottom of the connecting rod 31. The first spring 32 is sleeved on the connecting rod 31, and the two ends of the first spring 32 are respectively connected to the fixed plate 2 and the rolling member 4. The rolling member 4 includes an assembly block 41 and a roller 42. The assembly block 41 is installed at the bottom of the connecting rod 31, and the bottom end of the first spring 32 is connected to the assembly block 41. A rolling groove is opened at the bottom of the assembly block 41, and the roller 42 is rotatably connected in the rolling groove.

[0022] In this embodiment, a marking member 5 is installed on the top of the rod-type elastic member 3. The marking member 5 includes a bar 51, a marking pen 52 and a bolt 53. The bar 51 is installed on the top of the connecting rod 31. A through hole is provided in the bar 51. The marking pen 52 slides horizontally through the through hole and abuts against the display member 6. The bolt 53 is threadedly connected to the bar 51 and pressed against the marking pen 52.

[0023] In this embodiment, a display member 6 is installed on the mobile trolley 1, and the marking member 5 is against the display member 6. The display member 6 includes a turntable 61, a display tube 62 and an elastic stopper 63. The turntable 61 is rotatably connected to the top of the mobile trolley 1, the display tube 62 is installed on the top of the turntable 61, and the elastic stopper 63 is installed on the turntable 61 for its own limit. The display tube 62 is provided with a display area, and the marking end of the marking pen 52 is against the display area on the display tube 62.

[0024] It should be noted that:

[0025] In order to facilitate the detection of the flatness of the backfill of the site, the mobile cart 1 can be moved on the filled site so that the roller 42 on the assembly block 41 rolls on the ground.
