Mechanical and hydraulic integrated dynamic compaction machine

Abstract

The invention discloses a mechanical and hydraulic integrated dynamic compaction machine. The mechanical and hydraulic integrated dynamic compaction machine comprises an engine, a main winch, a walking system, a hydraulic system driving the walking system to act, and a transmission system, wherein the transmission system comprises a transfer case which is connected with an output shaft of the engine, power of the engine is transmitted to the main winch and the hydraulic system of the dynamic compaction machine through the transfer case, a first speed reducing assembly is arranged in the transfer case, and the engine is connected with the main winch through the first speed reducing assembly so that the main winch can be driven to rotate in the positive direction; a second speed reducing assembly is further arranged in the transfer case, and the engine is connected with the main winch through the second speed reducing assembly so that the main winch can be driven to rotate in the reverse direction. According to the mechanical and hydraulic integrated dynamic compaction machine, the engine can drive the main winch to rotate in the reverse direction, then a tamper or a weight is driven to be placed downwards, and the tamper can be placed downwards quite stably due to the fact that the engine drives the winch to rotate continuously; in addition, the application flexibility of the machine is further improved due to the fact that a heavy load can be placed down by the dynamic compaction machine, and cost of devices used on a construction site can be reduced to a certain degree.

Description

technical field [0001] The invention relates to the technical field of dynamic ramming machines, in particular to a mechanical-hydraulic integrated dynamic ramming machine. Background technique [0002] According to the different transmission modes of the dynamic compactor, the dynamic compactor can be divided into the following categories: full hydraulic transmission, full mechanical transmission and machine-hydraulic integrated transmission. Among them, the mechanical-hydraulic integrated transmission combines the advantages of mechanical transmission and hydraulic transmission. The main winch transmission of dynamic tamping adopts mechanical transmission, and other working actions adopt hydraulic transmission. It is the most widely used transmission mode of dynamic tamping machine at present. . [0003] The machine-hydraulic integrated transmission device includes the engine, transfer case, main winch, hydraulic system and other working parts. The power of the engine is ...

AI Technical Summary

Problems solved by technology

[0005] However, when the point braking friction belt is working, the braking force is intermittent and extremely unstable, so that the heavy object cannot be lowered smoothly, and the heavy object may be damaged when it reaches the ground.

On the other hand, the wear and heat of the brake belt are very serious, which will damage the main winch and the brake belt, and the point brake function cannot be used for a long time.
