Description

Technical Field

[0001] This application relates to the field of foundation construction, and particularly to an efficient compaction device for foundation backfilling. Background Art

[0002] After the foundation pit is dug, a protective plate is set around the foundation pit, and then the filler is backfilled into the foundation pit. Then, the excavator is used for preliminary compaction, and a compaction device is further used for compaction. For commonly used small compaction devices, the pressing plate is driven by the rotation of the eccentric cam to impact the ground, but the compaction efficiency is low, resulting in a reduction in construction efficiency. Utility Model Content

[0003] In order to improve the compaction efficiency, this application provides an efficient compaction device for foundation backfilling.

[0004] An efficient compaction device for foundation backfilling provided by this application adopts the following technical solutions:

[0005] An efficient compaction device for foundation backfilling includes a bottom plate, a compaction frame rotatably arranged on the bottom plate, and a compaction component for driving the compaction frame to impact the ground. A support block is arranged on the top surface of the bottom plate, and a first main shaft is rotatably connected to the support block. The compaction frame includes two connecting parts and a compaction plate connecting the two connecting parts. The two connecting parts are rotatably connected to the first main shaft.

[0006] The compaction component includes a second main shaft and several groups of compaction structures. The two ends of the second main shaft are rotatably connected to the two connecting parts. The second main shaft is parallel to the first main shaft and is located above the compaction plate. The compaction structure includes a compaction synchronous pulley and two eccentric cams. The eccentric cams are located on both sides of the compaction synchronous pulley. The compaction synchronous pulley is coaxially fixed to the second main shaft, and the eccentric cams are fixed to the second main shaft. Several compaction structures are arranged on the second main shaft; a driving mechanism for driving the compaction synchronous pulley to rotate is further included.

[0007] By adopting the above technical solutions, during use, the driving mechanism drives the compaction synchronous pulley to rotate, and the eccentric cams rotate along the second main shaft, causing the compaction frame to swing along the first main shaft, and the compaction plate repeatedly impacts the ground to achieve the compaction effect. The worker moves the bottom plate to change the compaction position. By arranging several groups of compaction structures, on the one hand, the compaction gravity is increased, resulting in a good compaction effect; on the other hand, the area of the compaction plate is increased, the force on the compaction plate is uniform, and the compaction area is increased, improving the compaction efficiency and construction efficiency.

[0008] Optionally, the two eccentric cams in the same group of compaction structures are fixed on both sides of the compaction synchronous pulley, and the protruding directions of the two eccentric cams are the same.

[0009] By adopting the above technical solution, by fixing two ramming synchronous wheels on both sides of the eccentric cam, the protruding positions of the two eccentric cams are kept consistent, and there is no need to install the eccentric cams one by one for adjustment, thus making the installation convenient.

[0010] Optionally, a connecting sleeve is arranged between two adjacent eccentric cams of different groups of ramming structures. The connecting sleeve is sleeved on the second main shaft, and connecting blocks are fixed on both sides of the connecting sleeve. Connecting grooves for inserting the connecting blocks are formed on the side walls of two adjacent eccentric cams close to the connecting sleeve.

[0011] By adopting the above technical solution, the connecting blocks are inserted into the connecting grooves of two adjacent eccentric cams, so that the connecting sleeve connects two adjacent ramming structures, improving the connection tightness of multiple groups of ramming structures. When the main shaft rotates, the eccentric cams on several ramming structures have good steering synchronism, so that the two ends of the bottom plate are stressed evenly and the ramming is uniform.

[0012] Optionally, the driving mechanism includes several transmission synchronous wheels coaxially fixed on the first main shaft. The several transmission synchronous wheels are arranged corresponding to several ramming synchronous wheels one by one. The transmission synchronous wheels and the ramming synchronous wheels are tensioned and connected by a synchronous belt; the driving mechanism further includes a driving motor for driving the first main shaft to rotate.

[0013] By adopting the above technical solution, the driving motor drives the first main shaft to rotate, driving the transmission synchronous wheels to rotate. The ramming synchronous wheels are rotated through the synchronous belt. The arrangement of multiple synchronous wheels makes the second main shaft stress evenly and the rotation stable.

[0014] Optionally, the driving mechanism further includes two stable synchronous wheels, two stable rods, two driving synchronous wheels and a gearbox. The two stable rods are rotatably connected to the bottom plate. The axes of the two stable rods coincide. The ends of the two stable rods close to each other are connected to the gearbox. The driving motor is connected to the gearbox, and the driving motor drives the two stable rods to rotate;

[0015] The two driving synchronous wheels are coaxially fixed to the two stable rods respectively. The stable synchronous wheels are coaxially fixed at both ends of the first main shaft in the length direction. The stable synchronous wheels and the driving synchronous wheels are tensioned and connected by a synchronous belt.

[0016] By adopting the above technical solution, the arrangement of the two stable synchronous wheels makes the two ends of the first main shaft rotate evenly. Thus, through the transmission synchronous wheels and the ramming synchronous wheels, the second rotating rod rotates evenly, and the ramming effect is good.

[0017] Optionally, the gearbox is a reduction box.

[0018] By adopting the above technical solution, the rotation speed of the eccentric cam during ramming is reduced to adapt to the operation of workers.

[0019] Optionally, a fillet is provided at the circumferential edge of the bottom surface of the bottom plate.

[0020] By adopting the above technical solution, it is convenient for the bottom plate to move on an uneven ground, and the raised obstacles on the ground are not likely to stop the movement of the bottom plate.

[0021] Optionally, a handle is provided on the bottom plate.

[0022] By adopting the above technical solution, it is convenient for workers to hold the handle to move the bottom plate, thus facilitating the movement of the ramming equipment.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. By arranging multiple groups of ramming structures, the ramming gravity is increased, resulting in a good ramming effect. On the other hand, the area of the ramming plate is increased, the force on the ramming plate is uniform, and the ramming area is increased, improving the ramming efficiency and construction efficiency.

[0025] 2. Two ramming synchronous wheels are fixed on both sides of the eccentric cam, so that the protruding positions of the two eccentric cams are kept consistent, and there is no need to install the eccentric cams one by one for adjustment, thus making the installation convenient.

[0026] 3. The connecting block is inserted into the connecting groove between two adjacent eccentric cams, so that the connecting sleeve connects two adjacent ramming structures, improving the connection tightness of multiple groups of ramming structures. When the main shaft rotates, the eccentric cams on several ramming structures have good steering synchronism, so that the forces at both ends of the bottom plate are uniform and the ramming is uniform.

The bottom ends of the two vertical plates 212 on the two connecting parts 21 are fixed to both ends of the ramming plate 22. The reinforcing rod 213 is located at the included angle between the connecting rod 211 and the vertical plate 212, and the end parts of the reinforcing rod 213 are respectively connected to the connecting rod 211 and the vertical plate 212.

[0036] Refer to Figure 2 , Figure 3, the ramming component 3 includes a second main shaft 31 and several groups of ramming structures 32. The two ends of the second main shaft 31 are rotatably connected to the tops of two vertical plates 212, and the second main shaft 31 is parallel to the first main shaft 14. The second main shaft 31 is located above the ramming plate 22. Each group of ramming structures 32 includes a ramming synchronous pulley 321 and two eccentric cams 322. The eccentric cams 322 are located on both sides of the ramming synchronous pulley 321, and the two eccentric cams 322 are fixed to both sides of the ramming synchronous pulley 321, and the protruding directions of the two eccentric cams 322 are the same.

[0037] Refer to Figure 2 , Figure 3 , the ramming synchronous pulley 321 is coaxially fixed to the second main shaft 31, and the eccentric cam 322 is fixed to the second main shaft 31 through the ramming synchronous pulley 321. Several ramming structures 32 are arranged on the second main shaft 31, and a connecting sleeve 33 is arranged between two adjacent eccentric cams 322 of different groups of ramming structures 32. The connecting sleeve 33 is sleeved on the second main shaft 31, and two connecting blocks 331 are protrudingly fixed on both sides of the connecting sleeve 33. Connecting grooves 332 for inserting the connecting blocks 331 are formed on the side walls of two adjacent eccentric cams 322 close to the connecting sleeve 33, and two adjacent eccentric cams 322 clamp the connecting sleeve 33.

[0038] Refer to Figure 1 , the high-efficiency ramming equipment for foundation backfilling further includes a driving mechanism 4 for driving the ramming synchronous pulley 321 to rotate. The driving mechanism 4 includes several transmission synchronous pulleys 41 coaxially fixed to the first main shaft 14. The several transmission synchronous pulleys 41 correspond to the several ramming synchronous pulleys 321 one by one, and the transmission synchronous pulley 41 and the ramming synchronous pulley 321 are tensioned and connected by a synchronous belt.

[0039] The driving mechanism 4 further includes two stable synchronous pulleys 42, two stable rods 43, two driving synchronous pulleys 44 and a gearbox 45. The two stable rods 43 are rotatably connected to the top surface of the bottom plate 1. The stable rods 43 are located between the first main shaft 14 and the handle 11, and the axes of the two stable rods 43 coincide. The ends of the two stable rods 43 close to each other are connected to the gearbox 45. The two driving synchronous pulleys 44 are coaxially fixed to the two stable rods 43 one by one.

The driving motor 46 drives the two stable rods 43 to rotate synchronously, and thus through the transmission of the stable synchronous pulley 42 and the driving synchronous pulley 44, the first main shaft 14 rotates. The gearbox 45 is a reduction box, which reduces the rotation of the first main shaft 14, thereby reducing the rotation of the second rotating shaft, so that the rotation speed of the eccentric cam 322 is reduced, which is convenient for workers to use.

[0041] The implementation principle of an efficient tamping device for foundation backfilling in an embodiment of this application is as follows: During use, the driving motor 46 drives the stabilizing rod 43 to rotate, driving the synchronous wheel 44 to rotate, causing the stabilizing synchronous wheel to rotate, thereby driving the first main shaft 14 to rotate. Then, through the transmission of the transmission synchronous wheel 41 and the tamping synchronous wheel 321, the eccentric cam 322 rotates. When the eccentric cam 322 rotates to a position where the center of gravity is above the second main shaft 31, the tamping frame 2 rotates around the first main shaft 14 and leaves the ground. When the eccentric cam 322 rotates to a position where the center of gravity is below the second main shaft 31, the tamping frame 2 drops and impacts the ground, thereby achieving reciprocating swinging and achieving a tamping effect. In this application, multiple groups of tamping structures 32 are arranged. On the one hand, it increases the tamping gravity, resulting in a good tamping effect. On the other hand, it increases the area of the tamping plate 22, the tamping plate 22 is evenly stressed, and the tamping area is increased, improving the tamping efficiency and the construction efficiency.

[0042] The above are all the preferred embodiments of this application. Without restricting the protection scope of this application based on this, therefore: Any equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
