Description

Technical Field

[0001] This utility model belongs to the field of foundation compaction technology in roadbed areas, and particularly relates to a foundation compaction construction device for roadbed areas. Background Technology

[0002] The roadbed area is the road construction zone used during the engineering construction process. During construction, to maintain the structural strength of the roadbed, it is necessary to compact it. Compaction increases the density of the roadbed, thereby preventing road surface cracking caused by roadbed settlement after construction.

[0003] Currently, the compaction method involves selecting different compaction equipment based on the length and width of the construction road. For example, for large roads with significant length and width, highly automated compaction equipment is used. For smaller projects, such as narrow roads, manual compaction is preferred.

[0004] Specifically, manual compaction offers greater flexibility and mobility, while large equipment operating in narrow roadbed areas suffers from lower mobility and flexibility, resulting in lower construction efficiency.

[0005] However, the drawbacks of manual compaction are also quite obvious, showing that the compaction efficiency is not high, especially in road areas with a slightly longer length. Although the road width is not large, the total length is high, resulting in a large workload for manual compaction work, even though the manual operation is highly flexible.

[0006] Specifically, existing manual compaction devices are mostly hammers and similar equipment. During the compaction process, it is necessary to manually lift the hammer repeatedly along the length of the road to compact the road. Therefore, they are only suitable for working on relatively short road areas.

[0007] For long roads, if manual compaction is still used, it is impossible to fully compact the roadbed along the length of the road in a short time. Utility Model Content

[0008] Based on the above background, the purpose of this utility model is to provide a foundation compaction construction device for roadbed areas.

[0009] To achieve the above objectives, the present invention adopts the following technical solution:

[0010] A roadbed area foundation compaction construction device includes a roadbed compaction mechanism, the roadbed compaction mechanism includes a mobile trolley, the mobile trolley includes a frame, and a compaction plate mechanism is fixedly connected to the end of the frame;

[0011] The tamping plate mechanism includes tamping frames spaced apart on both sides, a tamping plate support slidably connected between the tamping frames, and a tamping plate fixedly installed at the bottom of the tamping plate support;

[0012] The tamping frame is fixedly connected to a spring sliding structure, and the tamping plate support is elastically raised and lowered via a spring sliding connection.

[0013] Several lifting ropes are fixedly connected to the top of the ramming plate;

[0014] The roadbed area foundation compaction construction device also includes several heavy-duty tamping structures rotatably connected in the frame. After initial heavy-duty tamping by the heavy-duty tamping structures, the tamping is further compacted by the tamping plate mechanism.

[0015] Preferably, the longitudinal cross-sectional shape of the ramming frame is rectangular;

[0016] The ramming frame is welded to the end of the vehicle frame, and a triangular connecting rib is welded between the ramming frame and the top of the vehicle frame.

[0017] Preferably, the tamping plate support includes U-shaped sections spaced apart at the front and rear, and a horizontal connecting section is integrally formed between the bottoms of the U-shaped sections. The horizontal connecting section is fastened to the top of the tamping plate by a plurality of fastening bolts.

[0018] A slide block is fixedly connected to the U-shaped part, and the slide block is slidably connected to the spring sliding structure.

[0019] Preferably, the spring sliding structure includes a vertical slide rod fixedly connected within the ramming plate bracket, and the slide block is slidably connected to the vertical slide rod;

[0020] A spring is fitted onto the vertical slide rod, and the two ends of the spring are fixedly connected to the bottom positions of the slide block and the tamping plate support, respectively.

[0021] Preferably, a platform is provided on the top of the vehicle frame, and a bracket is welded to the bottom of the platform, the bracket being welded and fixedly connected to the top of the vehicle frame.

[0022] Preferably, a dust cover is fixedly installed between the tops of the tamping frame, and a through-hole is provided on the dust cover, through which the lifting rope passes.

[0023] Preferably, lower fixing rings are fixedly connected to the top two sides of the ramming plate, and the lower end of the lifting rope is fixedly connected to the lower fixing rings;

[0024] The upper end of the lower fixing ring is fixedly connected to the upper pull ring, and the upper end of the lifting rope is fixedly connected to the upper pull ring.

[0025] Preferably, the heavy-duty rammer structure includes a heavy-duty rammer roller rotatably connected within the frame, and a plurality of piercing heads are fixedly connected to the heavy-duty rammer roller.

[0026] Preferably, a plurality of drive wheels are installed on the front and rear side walls of the vehicle frame.

[0027] This utility model has the following beneficial effects:

[0028] 1. During the operation, the operator stands on the platform and moves with the mobile trolley. During this movement, the tamping plate is continuously lifted and then released, after which it is slammed back onto the roadbed. Because of the mobile trolley method, rapid and efficient compaction is achieved even on long, narrow roads. This method of automatically compacting the roadbed is not only highly efficient and thorough, but also offers high mobility and flexibility.

[0029] 2. During the working process, the heavy-duty tamping roller first compacts the roadbed using a preliminary roller compaction method. Through the use of barbed heads on the rotating heavy-duty tamping roller, these barbed heads press against the roadbed, especially crushing stones and rocks, thus increasing the density of the roadbed after compaction. Furthermore, the pressure and compaction of the heavy-duty tamping roller, combined with the compaction plate, further enhances the overall compaction effect of the device.

[0039] Example 1

[0040] like Figure 1-4 As shown, a roadbed foundation compaction construction device includes a roadbed compaction mechanism, which includes a mobile trolley. The mobile trolley includes a frame 1 (a steel frame with a rectangular cross-section). A pair of drive wheels 11, spaced apart from each other, are respectively installed on the front and rear side walls of the frame 1. Specifically, it adopts a conventional wheel-driven rotation method disclosed in the prior art. A hub motor is fixedly installed at the center of the hub of the drive wheel 11, and the output shaft of the hub motor is fixed to the frame 1. When the hub motor works, the hub motor body carries the drive wheel 11 to rotate.

[0041] A tamping plate mechanism is fixedly connected to the left end of the frame 1.

[0042] Specifically, the tamping mechanism includes tamping frames spaced apart on both the front and rear sides, with the longitudinal cross-sectional shape of the tamping frames being rectangular. To improve the structural stability of the tamping frames, these frames are welded to the ends of the vehicle frame 1, and a triangular connecting rib 13 is welded between the tamping frames and the top of the vehicle frame 1. The triangular connecting rib 13 further enhances the structural stability between the tamping frames and the vehicle frame 1.

[0043] The above-mentioned tamping frames are slidably connected by a tamping plate support 32 (at the same time, a tamping plate is fixedly installed at the bottom of the tamping plate support 32). Specifically, the tamping plate support 32 includes U-shaped parts arranged at intervals in front and behind (the U-shaped parts are in an inverted downward position). A horizontal connecting part is integrally formed between the bottoms of the U-shaped parts. The horizontal connecting part is fastened to the top of the tamping plate by a number of fastening bolts.

[0044] Meanwhile, a spring sliding structure is fixedly connected inside the tamping frame, and the tamping plate support 32 is elastically raised and lowered via a spring sliding connection. Specifically, the spring sliding structure includes a vertical slide rod 34 fixedly connected inside the tamping plate support 32 (the vertical slide rod 34 is welded and fixed to the center part inside the tamping plate support 32), and a slide seat 321 fixedly connected to the U-shaped part (the slide seat 321 is welded to the tamping plate support 32 via a connecting rod 3211). The slide seat 321 is slidably connected to the spring sliding structure. Specifically, the slide seat 321 is slidably connected to the vertical slide rod 34.

[0045] A spring 35 is sleeved on the vertical slide bar 34, and the two ends of the spring 35 are respectively fixedly connected to the bottom position inside the slide block and the ramming plate support 32.

[0046] In order to improve the sliding stability of the tamping plate 31, guide slide rods 33 are welded on both sides inside the tamping plate support 32. Correspondingly, side slides located on both sides of the slide 321 are welded on the U-shaped part, and the side slides are slidably connected to the guide slide rods 33.

[0047] The top of the aforementioned tamping plate 31 is fixedly connected with several lifting ropes 33; specifically, lower fixing rings are fixedly connected to both sides of the top of the tamping plate 31, and the lower ends of the lifting ropes 33 are fixedly connected to the lower fixing rings; the upper ends of the lower fixing rings are fixedly connected to the upper pull rings, and the upper ends of the lifting ropes 33 are fixedly connected to the upper pull rings 331.

[0048] Meanwhile, a platform 12 is provided on the top of the frame 1, and a bracket is welded to the bottom of the platform 12. The bracket is welded and fixedly connected to the top of the frame 1.

[0049] During the operation, the operator stands on the platform and moves with the mobile trolley. During the movement, the tamping plate is continuously lifted and then the lifting force is released. The tamping plate is then tamped back onto the roadbed. Because the tamping is done by moving the trolley, it is possible to quickly and efficiently tampe narrow roads with long road lengths.

[0050] During this process, the elastic restoring force of spring 35 is used to assist in raising and resetting the tamping plate after it has been re-tamped.

[0051] Example 2

[0052] like Figure 1-4As shown, in this embodiment, based on the structure of Embodiment 1, a dust cover plate 4 is fixedly installed between the top of the above-mentioned tamping frame. A through-hole 41 is provided on the right side wall of the dust cover plate 4, through which the lifting rope passes. The dust cover plate 4 prevents a large amount of dust from flying near the workers during the compaction process. The bottom of the dust cover plate 4 is fixedly connected to the top of the tamping frame by a fixing rod 42.

[0053] Example 3

[0054] like Figure 1-4 As shown, based on the structure of Embodiment 2, the above-mentioned roadbed area foundation compaction construction device further includes a pair of heavy-duty ramming structures rotatably connected in the frame 1. After initial heavy-duty ramming by the heavy-duty ramming structures, it is compacted again by the ramming plate mechanism.

[0055] The heavy-duty rammer structure includes a heavy-duty rammer roller 2 rotatably connected within the frame 1, and a plurality of piercing heads 21 are fixedly connected to the heavy-duty rammer roller 2. The piercing heads 21 are welded to the heavy-duty rammer roller 2, and their ends are curved.

[0056] During operation, the heavy-duty tamping roller 2 first compacts the roadbed using a preliminary roller compaction method. The tamping roller 2 is equipped with barbed heads 21, which press against the roadbed during operation, especially crushing stones and rocks. This increases the compactness of the roadbed after compaction. Furthermore, the pressing and compaction by the heavy-duty tamping roller 2, in conjunction with the tamping plate, further enhances the overall compaction effect of the device.

[0057] Of course, the above description is not intended to limit the present utility model, and the present utility model is not limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the present utility model should also fall within the protection scope of the present utility model.
