Description

Technical Field

[0001] The utility model relates to the technical field of construction backfilling, in particular to a backfilling device for water conservancy project construction. Background Art

[0002] Earth backfilling is the filling soil of construction projects, mainly including foundation soil filling, foundation pit or trench backfilling, indoor floor backfilling, outdoor site backfilling and leveling, etc. For the backfill soil on both sides or around and above the underground facility project, various inspections of the underground project should be carried out first, and the acceptance procedures should be completed before backfilling.

[0003] According to the "A Soil and Rock Backfilling Device for Water Conservancy Projects" disclosed in the Chinese Patent Publication No. CN219386272U, the device drives the rotating shaft to rotate through a driving motor, then the rotating shaft drives the turntable to rotate, and at the same time the turntable drives the fixed block to rotate and drives the fixed ring to move upward from bottom to top. Then the fixed ring drives the ramming plate to move upward through the connecting rod. When the fixed block is separated from the fixed ring, the ramming plate moves downward under the influence of gravity, and compacts and extrudes the earthwork backfill below by its own weight. Since the connecting rod and the fixed ring do not contact the turntable and the fixed block during the falling process, the height can be adjusted according to the condition of the backfill. At the same time, the movable plate and the spring are used to store energy when the connecting rod rises through, and when the connecting rod moves downward, it provides enough initial speed to increase the impact force of the ramming plate. Since the fixed block and the fixed ring are movably connected, the normal operation of the mechanical equipment is effectively protected.

[0004] The device rams the earthwork backfill pit through the ramming plate. However, when ramming the backfill pit, it will squeeze the earthwork below the ramming plate, and the earthwork in the backfill pit is squeezed out, causing the earthwork in the backfill pit to sink and the surface of the backfill pit to be uneven.

Detailed implementation manner

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0021] Referring to Figures 1 - 3 , a water conservancy project construction backfilling device, including a support frame 1, a working box 2 is fixedly connected to the top of the support frame 1, two fixed plates 3 are fixedly connected to the inner wall of the working box 2. Further, a water tank 16 is installed between the fixed plate 3 and the inner wall of the working box 2, and a spraying plate 17 connected to the water tank 16 is installed on the outer side wall of the working box 2. A plurality of nozzles arranged at equal intervals are installed on the spraying plate 17. By setting the water tank 16 and the spraying plate 17, during the process of ramming the soil, the spraying plate 17 can spray the area near the water conservancy project construction backfilling device, thereby effectively achieving the dust reduction effect and avoiding the impact of dust flying on the working environment and the health of workers;

[0022] In addition, specifically for the water tank 16 and the spraying plate 17, a water pump is installed inside the water tank 16, and the output end of the water pump is connected to the input end of the spraying plate 17 through a pipeline;

[0023] A bottom plate 4 is fixedly connected between the two fixed plates 3, a servo motor 5 is installed on the top of the working box 2 located at the top of the bottom plate 4, and the servo motor 5 is connected to a ramming plate 9 through a driving component. Further, the driving component includes a linkage screw 6 connected to the output end of the servo motor 5, a driving slide plate 7 is threadedly connected to the linkage screw 6, two connecting rods 8 are fixedly connected to the bottom of the driving slide plate 7, and the ends of the connecting rods 8 are fixedly connected to the top of the ramming plate 9. By setting the driving component, when performing the ramming work, the servo motor 5 is started to drive the linkage screw 6 to rotate. At this time, since the driving slide plate 7 is slidably connected to the side wall of the fixed plate 3, as the rotation direction of the linkage screw 6 is different, the driving slide plate 7 can drive the ramming plate 9 to move up and down through the connecting rod 8, thereby realizing the ramming of the soil;

[0024] Further, the end of the linkage screw 6 is rotatably connected to the top of the bottom plate 4, both sides of the driving slide plate 7 are fixedly connected to the side wall of the fixed plate 3, and the connecting rod 8 penetrates through the bottom plate 4 and is slidably connected thereto.

[0025] Fixing grooves are formed on both sides of the ramming plate 9. A fixing rotating shaft 10 is fixedly connected to the inner wall of the fixing groove. A linkage rod 11 is rotatably connected to the fixing rotating shaft 10. By providing the linkage rod 11, when the ramming plate 9 moves downward, since the two ends of the linkage rod 11 are respectively rotatably connected to the connecting rotating shaft 12 and the fixing rotating shaft 10 and its length remains unchanged, the bottom of the pushing plate 9 can be pushed to move outward with the support rotating shaft 15 as the center. Similarly, when the ramming plate 9 moves upward, the fixing rotating shaft 10 can pull the end of the linkage rod 11 to move upward, thereby pulling the bottom of the pushing plate 9 to move inward, so that the soil extruded during the process of the ramming plate 9 tamping the soil downward can be pushed back under the ramming plate 9 again when the ramming plate 9 moves upward, effectively avoiding the settlement of the backfill pit soil and the unevenness of the backfill pit surface;

[0026] The end of the linkage rod 11 is rotatably connected to a connecting rotating shaft 12. The connecting rotating shaft 12 is connected to a pushing plate 14 through a connecting member. Further, the connecting member includes two connecting plates 13 fixedly connected to the side wall of the pushing plate 14. The two ends of the connecting rotating shaft 12 are respectively fixedly connected to the side walls of the two connecting plates 13;

[0027] Further, a support rotating shaft 15 is rotatably connected to the top of the pushing plate 14. The two ends of the support rotating shaft 15 are fixedly connected to the inner wall of the working box 2.

[0028] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered by the protection scope of the present invention.
