Description

Technical Field

[0001] The utility model relates to a compaction device, in particular to a compaction device for improving the backfill compaction degree of a dike-penetrating structure, and belongs to the technical field of backfill compaction. Background Art

[0002] A through-embankment building refers to a building whose foundation or part of the main body is below, in the middle or above the embankment, such as some docks, ferries, buildings close to the river, and drainage projects. During the construction of the structure, after the foundation construction is completed, backfilling is required to improve the safety of the building. During backfilling, the backfill soil needs to be compacted so that the foundation has the load-bearing capacity of the design specified value and reduces the occurrence of deformation such as settlement. During the compaction process, some larger lumps can easily cause the compacting wheel of the compacting device to deform or even burst. Therefore, in order to improve the compaction quality of the backfill soil, the compacting wheel needs to be replaced.

[0003] When replacing a deformed and burst pressure wheel of the existing compaction device, it requires the joint efforts of multiple people and the use of tools to remove the pressure wheel. This method is not only labor-intensive, time-consuming and labor-intensive, but also has low replacement efficiency. In addition, when the inside of the foundation pit is relatively humid, the pressure wheel is prone to stick to the soil during compaction work, which not only affects the forward speed of the compaction device, reduces the compaction work efficiency, but also affects the compaction work quality.

[0031] Please refer to Figure 3 The compacting mechanism 4 includes a motor 401 and a cylinder 408. A bidirectional screw 402 is fixed to the output end of the motor 401. Two symmetrical sliding links 403 are threadedly connected to the outer surface of the bidirectional screw 402. Two symmetrical support rods 404 are arranged at the bottom ends of the two sliding links 403. The outer surfaces of the two support rods 404 are rotatably connected to the pressure wheel 2. A cross bar 409 is fixed to the output end of the cylinder 408. Both ends of the cross bar 409 are rotatably connected to the rotating wheel 410. When the pressure wheel 2 needs to be replaced, the compacting mechanism is started. The motor 401 in 4 can make the two sliding links 403 move away from each other, thereby driving the two support rods 404 to be pulled out from the pressing wheel 2, easily removing the restriction of the pressing wheel 2 and the device. After replacing the new pressing wheel 2, the motor 401 is started again to make the two sliding links 403 move towards each other, which can drive the two support rods 404 to be inserted into the pressing wheel 2 at the same time, so that the support rods 404 are rotatably connected with the pressing wheel 2, thereby easily realizing the rapid replacement of the deformed and burst pressing wheel 2, saving time and effort, and greatly reducing the labor intensity of workers.

[0032] Each sliding link 403 is provided with a through slot 405 inside, and a slider 406 is slidably connected inside the through slot 405. A spring 407 is fixed between the upper surface of each slider 406 and the inner top wall of the through slot 405, and the ends of the two support rods 404 that are away from each other are fixed to the two sliders 406 respectively; due to the setting of the spring 407, the two sliders 406 and the support rod 404 can slide upward in the through slot 405, thereby driving the pressure wheel 2 to move upward, and in conjunction with the start cylinder 408, the cross bar 409 can drive the rotating wheel 410 to move up and down. Since the rotating wheel 410 is always in contact with the outer surface of the pressing wheel 2, the pressing wheel 2 can continuously compact the backfill soil while the rotating wheel 410 moves up and down;

[0033] A fixing block 411 is fixed to the bottom surface of the fixing frame 3, the outer surface of the bidirectional screw rod 402 is rotatably connected to the fixing block 411, the outer surface of the cylinder 408 is fixed to the bottom surface of the fixing block 411, and the outer surface of the rotating wheel 410 is always in contact with the outer surface of the pressure wheel 2.

[0034] Two symmetrical grooves 412 are formed inside the fixing frame 3 , and the top ends of the two sliding connecting rods 403 are slidably connected to the two grooves 412 respectively.

[0035] The outer surface of the bidirectional screw rod 402 is rotatably connected to the fixing frame 3 , and the outer surface of the motor 401 is fixed to the outer surface of the fixing frame 3 .

[0036] Please refer to Figure 4 The scraper mechanism 5 includes two fixed rods 501, each of which has a slide groove 502 inside. A slide rod 503 is slidably connected between the two fixed rods 501 through the slide groove 502. A spring 2 504 is fixed between the slide rod 503 and the inner top wall of the two slide grooves 502. A scraper 505 is clamped on the bottom surface of the slide rod 503. Under the action of the spring 2 504, the scraper 505 can always be in contact with the outer surface of the pressure wheel 2, so that the mud adhering to the outer surface of the pressure wheel 2 can be scraped off, avoiding the situation that the pressure wheel 2 is adhered to the mud and the forward speed of the compacting device is slowed down, thereby improving the compaction work efficiency and work quality;

[0037] The top ends of the two fixing rods 501 are fixed to the fixing frame 3 .

[0038] The bottom end of the scraper 505 is always in contact with the outer surface of the pressing wheel 2.

[0039] Working principle: when the backfill soil needs to be compacted, the power system in the power box 1 can be used to enable the driving wheel 7 to drive the pressure wheel 2 to roll forward. Due to the setting of the spring 1 407, the two sliders 406 and the support rod 404 can slide upward in the through groove 405, thereby driving the pressure wheel 2 to move upward. In conjunction with the start cylinder 408, the cross bar 409 can drive the rotating wheel 410 to move up and down. Since the rotating wheel 410 is always in contact with the outer surface of the pressure wheel 2, the rotating wheel 410 can continuously compact the backfill soil while moving up and down; when the outer surface of the pressure wheel 2 is adhered to the soil, under the action of the spring 2 504, the scraper 505 can always be in contact with the outer surface of the pressure wheel 2, thereby being able to remove the soil adhered to the outer surface of the pressure wheel 2 The soil is scraped off cleanly to avoid the situation where the pressure wheel 2 sticks to the soil and slows down the forward speed of the compacting device, thereby improving the compaction work efficiency and work quality; when the pressure wheel 2 needs to be replaced, starting the motor 401 in the compacting mechanism 4 can make the two sliding connecting rods 403 move away from each other, thereby driving the two support rods 404 to be pulled out from the pressure wheel 2, and easily removing the restrictions on the pressure wheel 2 and the device. After replacing the new pressure wheel 2, starting the motor 401 again makes the two sliding connecting rods 403 move towards each other, which can drive the two support rods 404 to be inserted into the pressure wheel 2 at the same time, so that the support rods 404 are rotatably connected to the pressure wheel 2, thereby easily realizing the rapid replacement of the deformed and burst pressure wheel 2, saving time and effort, and greatly reducing the labor intensity of workers.
