Description

technical field [0001] The invention belongs to the technical field of engineering machinery, in particular to a self-propelled intelligent continuous dynamic compaction machine. Background technique [0002] The compaction quality of highway subgrade filling will directly affect the settlement deformation and stability of subgrade, so the compaction degree of subgrade filling must be strictly controlled during construction. [0003] At present, the relevant equipment for subgrade compaction in my country is mainly ordinary road rollers (including single-wheel, double-wheel, rubber tires), dynamic compactors, impact rollers, and other small machinery. Ordinary road rollers have the advantages of good compaction continuity and high surface flatness. At the same time, if it is a vibratory road roller, it can also increase the effective depth of compaction and improve compaction efficiency. At present, Germany has developed BTM compaction monitoring equipment, which can real-ti...

AI Technical Summary

Problems solved by technology

Ordinary road rollers have the advantages of good compaction continuity and high surface flatness. At the same time, if it is a vibratory road roller, it can also increase the effective depth of compaction and improve compaction efficiency. At present, Germany has developed BTM compaction monitoring equipment, which can real-time Self-inspection and control of compaction, but the equipment price is high, and the compaction work of ordinary road rollers is low, and it needs to be compacted back and forth to achieve the compaction effect. The effective depth of compaction is also limited, generally 1m ~ 2m

[0004] The dynamic tamping machine in the prior art has a large impact depth of tamping, which can reach 5m to 10m, and a single point compaction degree is high. Generally, it only needs to be tamped 1 to 3 times to achieve the required compaction degree, but in the prior art The dynamic compaction machine requires large-scale mechanical operations such as cranes or gantry frames. At the same time, it is generally compacted at a single point, resulting in low compaction efficiency. At the same time, it is troublesome to detect the degree of compaction and has high requirements for the site. Personnel are highly dangerous and have a great impact on surrounding buildings

The impact rollers in the prior art have large compaction thickness and compaction impact depth, and good continuity, but require large-scale mechanical traction, and at the same time have a large impact on the surrounding structure, and have insufficient compaction detection efficiency.

However, other small compactors in the prior art are only suitable for local reinforcement and repair of road surface potholes. The application range is small and the compaction effect is poor. It is time-consuming and cannot meet the needs of actual use.

[0005] In order to solve the above problems, the Chinese patent application No. 201210234020.6 discloses an intelligent continuous dynamic compaction machine. The dynamic compaction machine can intelligently and continuously compact, and at the same time, the compaction work is relatively large, and the compaction thickness and compaction influence depth are large. However, in During use, it was found that the dynamic compaction machine also has the following defects and deficiencies: (1) The dynamic compaction machine uses a loader as the traction device. Due to the poor off-road performance and stability of the loader, the climbing force is small, and it is difficult to turn The radius is large, and after stopping at one position, the tamping mechanism cannot rotate 360° on it, the flexibility is poor, and it cannot walk by itself according to the predetermined walking distance and walking speed, and the conversion of the tamping point is inconvenient , thus limiting the popularization and use of the dynamic compaction machine; (2) one end of the flexible connecting body connected to the rammer in the dynamic compaction machine is fixedly connected with the frame. During the compaction process, the traction force of the rammer to the frame is large. , it is easy to cause the deformation of the frame, and finally the falling position of the rammer will be different from the expected position, which will affect the compaction accuracy
