Description
Technical Field
[0001] The present invention relates to the field of construction technology, and particularly to an earthwork backfilling and tamping device for building construction. Background Art
[0002] With the acceleration of the urbanization process and the continuous advancement of infrastructure construction, the market demand for earthwork backfilling construction in building construction is increasing continuously. As a key tool to ensure the quality of backfill soil and improve construction efficiency, the importance of the earthwork backfilling and tamping device is becoming increasingly prominent.
[0003] After retrieval, a Chinese patent with the patent publication number CN118653450B discloses an earthwork backfilling and tamping device, which includes a frame and a tamper suspended on the frame. The tamper is used for tamping the ground. A tamping rod is arranged on the tamping surface of the tamper. The length direction of the tamping rod is perpendicular to the tamping surface of the tamper. A plurality of tamping rods are provided. The tamping rods are arranged circumferentially along the axis of the tamper and extend towards the edge of the tamper. The circumferentially arranged tamping rods adjacent to each other are staggered.
[0004] The above patent compacts the backfill soil by the fall of the tamper, and the backfill soil is gradually compacted.

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 efforts shall fall within the protection scope of the present invention.
[0032] Embodiment 1:
[0033] Please refer to Figures 1 - 2 , the present invention provides a technical solution: An earthwork backfilling and ramming device for building construction, including a rammer body 1 as the main frame of the device.

A rotating shaft 5 is provided on the rammer body 1, one end of the rotating shaft 5 is connected to the belt drive structure 3, a rope winding drum 6 is fixedly connected to the outer wall of the rotating shaft 5, a steel wire rope 7 is wound around the rope winding drum 6, and one end of the steel wire rope 7 is fixedly connected to a rammer 8;
[0034] A bearing frame 9 is provided at the front end of the rammer body 1, and a clamping structure 11, a soil scraping assembly 12, and a secondary cleaning structure 13 are provided on the bearing frame 9. The clamping structure 11 is used to clamp and fix the rammer 8, the soil scraping assembly 12 is used to scrape the soil adhered to the surface of the rammer 8, and the secondary cleaning structure 13 is used to spray water and perform secondary cleaning on the surface of the rammer 8.
[0035] Among them, one outer wall of the water tank 131 is fixedly connected with a second mounting plate 136.

[0036] In this embodiment, the first motor 4 is started. The rotating shaft 5 and the rope winding cylinder 6 are driven to rotate through the belt transmission structure 3, winding or releasing the steel wire rope 7 to vertically lift and lower the rammer 8. When the rammer 8 is lowered, it freely falls under the action of gravity to impact the ground to complete the compaction of the soil; when the rammer 8 is lifted, the first motor 4 rotates in the reverse direction to wind up the steel wire rope 7, lifting the rammer 8 to a set height to prepare for the next ramming.
[0037] Among them, a handrail 2 is fixedly connected to the top outer wall of the rammer body 1, and an anti-slip rubber layer is provided on the surface of the handrail 2.
[0038] In this embodiment, the anti-slip rubber layer on the surface of the handrail 2 increases the friction when holding, preventing the operator from slipping when pushing the equipment or operating the buttons, and significantly improving the operation stability especially in humid or muddy environments.
[0039] Among them, a pulley 10 for guiding the steel wire rope 7 is provided on the carrier 9, and the steel wire rope 7 bypasses the pulley 10 at the top of the carrier 9 and is connected to the rammer 8.
[0040] In this embodiment, the pulley 10 at the top of the carrier 9 guides the movement path of the steel wire rope 7, reducing the direct friction between the steel cable and the carrier 9, ensuring the vertical lifting and lowering of the rammer 8 while reducing the wear degree, and avoiding the deviation of the ramming position or the shaking of the equipment caused by the deviation of the steel cable.
[0041] Example 2:
[0042] Please refer to Figures 1 - 5 As shown, on the basis of the first embodiment, the present invention provides a technical solution: The clamping structure 11 includes a chute 111, a first lead screw 112, a second motor 113, a clamping plate 114 and a clamping ring 115.

Two opposite threads are provided on the outer wall of the first lead screw 112, and the thread directions in contact with the two clamping plates 114 are opposite.
[0043] In this embodiment, after the rammer 8 is lifted to the cleaning station, the second motor 113 is started to drive the first lead screw 112 to rotate. Since two sections of reverse threads are provided on the surface of the first lead screw 112, the two clamping plates 114 that are in threaded engagement therewith slide towards each other along the chute 111, and the top of the rammer 8 is clamped through the clamping ring 115 to ensure that the position of the rammer 8 is fixed during the soil cleaning process and to avoid shaking from affecting the cleaning effect.
[0044] Embodiment 3:
[0045] Please refer to Figures 6 - 10 As shown, on the basis of Embodiment 1 and Embodiment 2, the present invention provides a technical solution: The soil scraping assembly 12 includes a second lead screw 121, a third motor 122, a slide bar 123, a scraper 124, a slide rail 125 and a moving block 126. The inner wall of the bearing frame 9 is rotatably connected to the second lead screw 121, the inner wall of the bearing frame 9 is fixedly connected to the slide bar 123, the second lead screw 121 and the slide bar 123 are arranged in parallel, a third motor 122 connected to the second lead screw 121 is arranged on the outer wall of one side of the bearing frame 9, moving blocks 126 are fixedly connected to the outer walls of the slide rails 125, the inner wall of one of the moving blocks 126 is in threaded connection with the outer wall of the second lead screw 121, and the inner wall of one of the moving blocks 126 is slidably connected to the outer wall of the slide bar 123.
[0046] The secondary cleaning structure 13 includes a water tank 131, a first mounting plate 132, a fixed pipe 133, a spray pipe 134, a water delivery pipe 135, a second mounting plate 136, a rotating roller 137, a brush 138, and a fourth motor 139. The water tank 131 is arranged at the bottom of the scraper 124, a first mounting plate 132 is fixedly connected to the outer wall of one side of the water tank 131, a fixed pipe 133 is fixedly connected between the outer walls of the two first mounting plates 132, a spray pipe 134 is fixedly connected to the outer wall of the fixed pipe 133, a water pump is arranged inside the water tank 131, the output end of the water pump is fixedly connected to the water delivery pipe 135, and one end of the water delivery pipe 135 is fixedly connected to the inner wall of the fixed pipe 133.
[0047] The outer wall of the bottom of the scraper 124 is fixedly connected to the slide rail 125, slide plates are fixedly connected to the outer walls of both sides of the water tank 131, and the water tank 131 is slidably connected to the inner wall of the slide rail 125 through the slide plates.
[0048] In this embodiment, the third motor 122 drives the second lead screw 121 to rotate, driving the moving block 126 that is in threaded connection with the second lead screw 121 to move accordingly. Under the limiting action of the slide bar 123, the moving block 126 moves horizontally, and the moving block 126 drives the scraper 124 to move horizontally therewith. The scraper 124 scrapes the soil adhering to the surface of the rammer 8, initially peeling off large pieces of soil.
[0049] The water pump in the water tank 131 starts, and the water flows through the delivery water pipe 135 to the fixed pipe 133. The spray pipe 134 evenly sprays the water onto the surface of the rammer 8 to soften the residual mud blocks. The motor four 139 drives the rotating roller 137 to rotate, and the rotating roller 137 rubs against the surface of the rammer 8 to brush off the wet mud.
[0050] Working principle: Push the rammer forward by holding the handle 2 by hand, start the motor one 4, drive the rotating shaft 5 and the rope winding drum 6 to rotate through the belt drive structure 3, wind or release the steel wire rope 7. The steel wire rope 7 bypasses the pulley 10 at the top of the bearing frame 9 to traction the rammer 8 to lift and lower vertically. When the rammer 8 is lowered, it freely falls under the action of gravity to impact the ground to complete the compaction of the earthwork; when the rammer 8 is lifted, the motor one 4 rotates in the reverse direction to wind up the steel wire rope 7 and lift the rammer 8 to the set height to prepare for the next ramming.
[0051] After the rammer 8 is lifted to the cleaning station, the motor two 113 starts and drives the lead screw one 112 to rotate. Since there are two sections of reverse threads on the surface of the lead screw one 112, the two clamping plates 114 that are threadedly engaged with it slide towards each other along the sliding groove 111, and clamp the top of the rammer 8 through the clamping ring 115 to ensure that the position of the rammer 8 is fixed during the soil cleaning process and avoid shaking from affecting the cleaning effect.
[0052] The motor three 122 drives the lead screw two 121 to rotate, driving the moving block 126 that is threadedly connected to the lead screw two 121 to move accordingly. Under the limiting action of the sliding rod 123, the moving block 126 moves horizontally, and the moving block 126 drives the scraper 124 to move horizontally therewith. The scraper 124 scrapes off the soil adhering to the surface of the rammer 8 to initially peel off the large soil blocks.
[0053] The water pump in the water tank 131 starts, and the water flows through the delivery water pipe 135 to the fixed pipe 133. The spray pipe 134 evenly sprays the water onto the surface of the rammer 8 to soften the residual mud blocks. The motor four 139 drives the rotating roller 137 to rotate, and the rotating roller 137 rubs against the surface of the rammer 8 to brush off the wet mud.
[0054] After the cleaning is completed, the motor two 113 rotates in the reverse direction, and the lead screw one 112 drives the clamping plate 114 to move in the reverse direction, and the clamping ring 115 releases the rammer 8. The motor one 4 drives the rope winding drum 6 to release the steel wire rope 7, and the rammer 8 falls again to compact the soil body, repeating the above process.
[0055] As mentioned above, it is only the preferred specific implementation manner 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 substitutions or changes, and should be covered by the protection scope of the present invention.
