Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction, and more specifically, to a tamping machine structure. Background Art
[0002] In the scenes of backfilling the back of culverts, backfilling the back of bridge abutments, and backfilling the back of retaining walls, before backfilling, a ruler with the same thickness as the compacted layer should be engraved on the back of the abutments, culverts, and walls, and the number of layers should be marked. Then, the backfill construction should be carried out, and the base should be compacted. After the compaction is completed, the upper layer should be laid to complete the backfill construction. Backfilling the back of culverts, backfilling the back of bridge abutments, and backfilling the back of retaining walls are key control points in highway construction. The quality of backfilling will directly affect the quality of the project. And base compaction is the key link of backfilling, which is related to the quality of backfilling.
[0003] In the prior art, large automatic tamping machines are generally used to compact the base. However, for small construction teams and in the scenarios of backfilling the back of culverts, backfilling the back of bridge abutments, and backfilling the back of retaining walls, large automatic tamping machines cannot be used due to construction costs and compaction site considerations. In the prior art, two workers are generally used to perform manual compaction using a jumping tamping machine; one worker pulls the jumping tamping machine in front to control the forward direction, and the other worker controls the jumping tamping machine to work upright. After compacting one layer, the tamping machine needs to be manually lifted out of the compaction area in order to backfill the next layer of filler. It takes 15 minutes to compact a single-side culvert back, which is time-consuming and labor-intensive.
[0004] Therefore, there is an urgent need for a tamping machine structure with low labor cost and high compaction efficiency. Utility Model Content

The engine of the excavator is generally a diesel engine. The drive unit is used to provide power for the construction work. The power of the engine is transmitted to the hydraulic motor, hydraulic cylinder and other actuators through the hydraulic pump to drive the working device to move, thereby completing various operations. The transmission unit may include a boom and a dipper and an operating end arranged at the front end of the dipper. In the utility model, the operating end is the tamping plate part.
[0029] Figure 2 FIG. 2 shows a schematic diagram of the structure of a mortar tape tool according to an embodiment of the utility model. Figure 2As shown, the connection part includes a connection rod 33 and a connection sleeve 31, and the end of the transmission unit 2 is inserted into the connection sleeve 31; a first stop bar is arranged in the connection sleeve, and a second stop bar is arranged at the end of the transmission unit, and the first stop bar and the second stop bar are abutted by the relative rotation of the connection sleeve and the transmission unit. In other words, the end of the transmission unit is placed in the connection sleeve, the connection sleeve is rotated, and the first stop bar is engaged with the second stop bar to achieve the connection between the connection part and the transmission unit, that is, the tamping plate part is connected to the power unit.
[0030] A reinforcing rib 33 is provided at the tamping plate connection end of the connection part to improve the connection strength between the connection part and the tamping plate part. In order to further improve the overall connection stability of the tamping plate part, the tamping plate part and the connection part are an integrally formed structure. The tamping plate part is a steel plate.
[0031] Example 2
[0032] A tamping machine structure is provided, including a tamping unit 3 and a power unit for driving the tamping unit; the tamping unit 3 includes a tamping plate portion 34 and a connecting portion for connecting the tamping plate portion 34 and the power unit; the power unit includes a traveling unit 1, a driving unit and a transmission unit 2; the driving unit and the transmission unit 3 are arranged on the traveling unit, and the transmission unit 2 is connected to the tamping unit 3; the driving unit drives the tamping unit through the transmission unit.

In other words, the tamping plate portion is pinned to the power unit.

If the vibration frequency is too high, the hard connection method of pin connection will easily reduce the service life of the tamping plate part. Therefore, the compaction effect is ensured by increasing the area of the tamping plate part and reducing the vibration frequency.

[0035] The utility model can greatly improve the working efficiency of backfill compaction operation, greatly reduce the labor intensity of workers, improve the working environment of operators, use the existing excavator for improvement, and save the investment of supporting equipment. The utility model has high overall structural strength, simple and reliable structure, flexible body, and can realize vibration operation and small-scale compaction operation through the detachable transmission end and tamping plate part of the excavator, and has strong adaptability.
[0036] The utility model has the technical effect of improving construction efficiency and reducing construction costs. In the prior art, taking the backfill of a 30m culvert on one side as an example, it takes two workers 30 minutes to complete one layer. According to the calculation of backfilling 10 layers on both sides, it takes two people 10 hours to complete; the economic cost is about 400×2×10 / 8=1000 yuan (400 yuan / work day per worker). By adopting the tamping machine device of the utility model, still taking the backfill of a 30m culvert on one side as an example, one layer requires a driver plus a Sany 240 excavator for 10 minutes (the driver's salary is 800 yuan / day, the fuel consumption is 15L / h, and the diesel is about 8 yuan per liter). Taking a circular culvert that needs to backfill 10 layers as an example, it takes an excavator 200 minutes to complete. The economic cost after improvement is: 15×8×200 / 60+800×200 / (60×8)=734 yuan; that is to say, the total cost of completing the backfill of the circular culvert normally is 1,000 yuan, and now 266 yuan is saved and the construction progress is accelerated.
[0037] The implementation process of the tamping machine device of the utility model is to drive the tamping machine device to the backfilling operation site through the walking unit, and drive the transmission unit through the power unit to drive the tamping plate part to compact the backfilling operation area. Specifically, for the part of the culvert that the roller cannot roll, the material required by the design drawings is used to backfill and then spread flat; first, the utility model tamping machine is used to compact the paved section. Because the compaction energy is large, the construction process of main tamping, auxiliary tamping, and full tamping is adopted in sequence, and the distance between the main tamping and the auxiliary tamping is 50cm; finally, the full tamping is used to shape and finish the rolled layer, and various construction parameters of the culvert backfill (compacting times, tamping energy, tamping spacing, loose paving thickness, etc.) are determined through the test section. After the compaction degree of the culvert meets the requirements of the drawings, the subsequent construction is carried out according to the construction parameters summarized in the test section, which ensures the safety and project quality and speeds up the on-site construction progress.
[0038] The utility model can greatly improve the working efficiency of backfill compaction operation, greatly reduce the labor intensity of workers, improve the working environment of operators, use the existing excavator for improvement, and save the investment of supporting equipment. The utility model has high overall structural strength, simple and reliable structure, flexible body, and can realize vibration operation and small-scale compaction operation through the detachable transmission end and tamping plate part of the excavator, and has strong adaptability.
[0039] As above Figure 1-Figure 2 The tamping machine structure according to the utility model is described in an exemplary manner. However, those skilled in the art should understand that various improvements can be made to the tamping machine structure proposed by the utility model without departing from the content of the utility model. Therefore, the protection scope of the utility model should be determined by the content of the attached claims.
