Dynamic compactor and single-rope double winding device thereof

Abstract

The invention discloses a dynamic compactor and a single-rope double winding device thereof. A double-winding-drum lifting device comprises two winding drums; the two ends of a steel wire rope are wound on the two winding drums respectively; the winding length on the two winding drums is the same; after compaction, a control device controls the two winding drums to rotate to roll up the steel wire rope; a compacting hammer is lifted; the control device calculates a length difference of the steel wire rope wound on the two winding drums during twice adjacent compacting hammer lifting; and the compacting depth is obtained. According to the dynamic compactor and the single-rope double winding device thereof, the compacting depth can be obtained automatically; heavy compaction can be free from unhooking; the problem that stress is different due to the fact that winding is not synchronous is solved; the operation efficiency is improved; dynamic compaction operation is safer, more reliable, more convenient and more comfortable; the operation cost of a user is lowered; and greater economic benefits are brought to the user.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a single-rope double winch device of a dynamic compactor and a dynamic compactor. Background technique [0002] At present, the general dynamic compaction construction adopts the single-rope single-winch non-decoupling technology or the double-rope double-hoist non-decoupling technology. These two construction technologies have high efficiency and good economy. Realize the technology of large ramming without decoupling. Although the double-rope double hoist can realize the technology of large ramming and non-decoupling, the double-rope double-hoist faces the problem of out-of-synchronization of hoisting, resulting in different forces on the two ropes, which are prone to failure or danger. Use and maintenance higher cost. Generally, a dynamic compaction machine is equipped with 3-4 people, and the manpower and material resources invested are relatively large, and th...

Problems solved by technology

[0002] At present, the general dynamic compaction construction adopts the single-rope single-winch non-decoupling technology or the double-rope double-hoist non-decoupling technology. These two construction technologies have high efficiency and good economy. Realize the technology of large ramming without decoupling. Although the double-rope double hoist can realize the technology of large ramming and non-decoupling, the double-rope double-hoist faces the problem of out-of-synchronization of hoisting, resulting in different forces on the two ropes, which are prone to failure or danger. Use and maintenance higher cost

Generally, a dynamic compaction machine is equipped with 3-4 people, which requires a lot of manpower and material resources, and the work efficiency is seriously affected by manual hooking and measurement. The dynamic compaction operation is a frequent reciprocating operation, and the human labor intensity is very high.

People are prone to fatigue, which can easily lead to safety accidents
