Transmission device and transfer case of machine-hydraulic integrated dynamic compaction machine

Abstract

The invention discloses a transmission device of a mechanical-hydraulic integrated dynamic compactor and a transfer case of the transmission device. A first speed reduction assembly is arranged in the transfer case, and an engine is connected with a main winch through the first speed reduction assembly and can drive the main winch to rotate in the forward direction. A second speed reduction assembly is further arranged in the transfer case, and the engine is connected with the main winch through the second speed reduction assembly and can drive the main winch to rotate in the backward direction. Power of the engine can be transmitted to the main winch through the second speed reduction assembly so that the main winch can be driven to unwind a rope. While the requirement of basic dynamic compaction work of equipment is met, the main winch can achieve the continuous dynamic compaction heavy load lowering function, so that the equipment has a wider application range; when a dynamic compaction heavy load has a fault in the lifting process but cannot be lowered down because the dynamic compaction height is not reached, the engine can drive the main winch to slowly lower down a rammer or a weight, and thus accidents are avoided. The power of the engine for driving the main winch is continuous, and thus the lowering stability of the rammer or the weight is good.

Description

technical field [0001] The invention relates to the technical field of transmission of the main winch of a dynamic compaction machine, in particular to a transmission device and a transfer case of a mechanical-liquid integrated dynamic compaction machine. Background technique [0002] According to the different transmission modes of the dynamic compaction machine, the dynamic compaction machine 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 eng...

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.
