Hoisting mechanism for dynamic compactor

Abstract

The invention discloses a hoisting mechanism for a dynamic compactor. The hoisting mechanism comprises a driving motor (1), a speed reducer (3), a reel (5), a brake (8), a spindle (9), an encoder (4) and a control device (10). The hoisting mechanism has the advantages that the hoisting mechanism is simple in structure, an internal expansion clutch is arranged in the reel, and the reel can be driven to rotate, so that the purpose of hoisting a rammer can be achieved; the hoisting mechanism is provided with the calipers brake, a rope pressing roller and the encoder, so that continuous falling of a steel wire rope can be controlled timely after the rammer falls to the ground, and steel wire rope twining and disorder phenomena due to the fact that the steel wire rope is excessively released can be prevented; the falling rammer can be quickly controlled by a control system and the encoder, accordingly, a working procedure for hooking and hoisting an existing rammer again in current construction procedures after the existing rammer is unhooked can be omitted, the construction intensity can be reduced, and potential safety hazards can be eliminated; the hoisting mechanism is compact in structure, convenient to use, high in work efficiency and suitable for large-scale popularization and application, and is safe and reliable.

Description

technical field [0001] The invention relates to mechanical equipment for civil engineering, in particular to a lifting mechanism for a dynamic compaction machine. Background technique [0002] In the process of dynamic compaction construction in existing civil works, hoists or hydraulic equipment are generally used to repeatedly lift the rammer to a specified height, and then release the rammer through the uncoupling device, and use the energy generated by the self-falling of the rammer to form a strong impact on the foundation, thereby To achieve the purpose of improving the bearing capacity of the foundation; in the construction process of this kind of technology, the rammer needs to be detached each time, and then hooked with the rammer through the decoupling device, and then the lifting cycle is repeated. Due to the structure of the existing lifting mechanism, when the rammer falls, the speed at which the hoist releases the wire rope is far from reaching the speed of the...

AI Technical Summary

Problems solved by technology

Due to the structure of the existing lifting mechanism, when the rammer falls, the speed at which the hoist releases the wire rope is far from reaching the speed of the free fall. To achieve the purpose of compacting the foundation, the structure of this type of lifting mechanism seriously restricts the speed at which the tamper can fall by itself, so that the entire workload is large, the construction process is labor-intensive, time-consuming, and extremely unsafe during the construction process
