Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering construction technology, and in particular to an earthwork compaction device for water conservancy engineering construction. Background Technology

[0002] In water conservancy engineering construction, earthwork compaction is a crucial step in ensuring project quality, affecting the stability and seepage prevention of hydraulic structures such as dams and canals. A common earthwork compaction device is the road roller, which relies on its own weight to generate static pressure on the paving material through its rollers, causing soil particles to rearrange and compact, thus achieving the compaction purpose. It is suitable for road base courses, subbase courses, and auxiliary fill compaction, and is frequently used in large-scale water conservancy projects for large-area fill compaction operations, such as the initial compaction of reservoir dams. Road rollers have a simple structure, are easy to operate, and provide stable compaction results, exhibiting good compaction effects on fine-grained soils and sandy soils.

[0003] Currently, the core requirement for compaction of earthmoving rollers in existing water conservancy projects is the uniform arrangement and tight interlocking of soil particles. Larger soil clods can disrupt this uniformity. However, in actual operations, large soil clods are often not completely removed, resulting in a soil area with a much higher hardness than the surrounding fine soil. When the roller compacts, the pressure is preferentially transmitted to the softer fine soil areas, leading to over-compaction and soil compaction in the soft areas. Meanwhile, loose areas remain around the soil clods, forming uneven stress zones. Especially for water conservancy projects, this unevenness can lead to a decrease in seepage prevention performance, allowing rainwater or water to easily seep into deeper layers through the gaps between soil clods, causing risks such as piping and leakage. Furthermore, the sharp edges of the soil clods may scratch the surface of the steel wheel, resulting in a decrease in the flatness of the steel wheel and the appearance of scratches or dents, which greatly affects subsequent construction operations.

[0022] Two sliding rods 9 are fixedly connected inside the mounting bracket 4, and two second connecting blocks 10 are fixedly connected to one side of the equipment mounting frame 5. Both sliding rods 9 pass through the corresponding second connecting blocks 10 and are slidably connected to the corresponding second connecting blocks 10.

[0023] Through the above technical solution, the two sliding rods 9 are slidably connected to the two second connecting blocks 10, which serves to support and fix the equipment mounting frame 5, and assist the equipment mounting frame 5 in lifting and lowering.

[0024] The mounting bracket 4 has a first telescopic sleeve 11 fixedly connected inside, and the telescopic rod of the first telescopic sleeve 11 is fixedly connected to one of the corresponding first connecting blocks 7.

[0025] Through the above technical solution, the first telescopic sleeve 11 is fixedly connected to one of the first connecting blocks 7, which serves to support and limit the equipment mounting frame 5, and assists the equipment mounting frame 5 in lifting and lowering.

[0026] Two second telescopic sleeves 20 are fixedly connected inside the equipment mounting frame 5, and the telescopic rods of the two second telescopic sleeves 20 are fixedly connected to the same C-shaped frame 18.

[0027] Through the above technical solution, the two second telescopic sleeves 20 play a role in supporting and fixing the C-shaped frame 18, and assist the C-shaped frame 18 in lifting and lowering.

[0033] In operation, the operator drives the equipment body 1 to the construction site, activates the first hydraulic telescopic rod 6, and the telescopic rod of the first hydraulic telescopic rod 6 extends and retracts, causing the first connecting block 7 to descend. The descent of the first connecting block 7 causes the connecting arm 8 to descend, and the descent of the connecting arm 8 causes the equipment mounting frame 5 to descend to a suitable height. Then, the servo motor 13 is activated, and the output shaft of the servo motor 13 rotates, causing the first synchronous wheel 14 to rotate. The rotation of the first synchronous wheel 14 causes the synchronous belt 16 to rotate, and the rotation of the synchronous belt 16 causes the second synchronous wheel 15 to rotate. The rotation of the second synchronous wheel 15 causes the crushing roller 12 to rotate, so that the equipment body 1 can break up large soil clods in front of it during the movement, making it easier to compact. At the same time, the second electric telescopic rod 17 is activated, and the telescopic rod of the second electric telescopic rod 17 extends and retracts, causing the U-shaped frame 18 to descend. The U-shaped frame 18 descends, causing the brush roller 19 to descend, sweeping up the broken soil clods so that they can be evenly spread on the ground, improving the flatness of the subsequent compaction work and completing the earthwork compaction work.
