Lifting mechanism of free dropping type forced ramming machine with hammer

Abstract

The invention discloses a lifting mechanism of a free dropping type forced ramming machine with a hammer, comprising a hoisting device hoisted with a hydraulic cylinder and a fixed pulley block, wherein the fixed pulley block is matched with a movable pulley block which is fixedly arranged on a sliding device, the hydraulic cylinder is connected with a detaching device corresponding to the sliding device, and the detaching device is selectively connected with and separated from the sliding device. The lifting mechanism of the free dropping type forced ramming machine with the hammer replaces a detacher and a hoisting mechanism widely used in the construction of the present forced ramming machine, realizes the lifting and non-detached ramming operation, has the advantages of convenient use and appropriate cost, and has important significance on enhancing the safety and the efficiency of ramming construction.

Description

technical field [0001] The invention belongs to the field of dynamic tamping construction equipment, in particular to a lifting mechanism of a free-falling type dynamic tamping machine with a hammer. Background technique [0002] At present, the hoisting and lifting mechanism is widely used in the construction process of dynamic compaction (the hoisting and hoisting mechanism is composed of a motor or an electric motor + a reducer + a reel with a clutch, and a brake is set on the high-speed end or the side of the reel). Lift to the specified height, release the rammer through the decoupling device, and use the energy generated by the free fall of the rammer to form a strong impact and vibration on the foundation, so as to increase the bearing capacity of the foundation, reduce the compressibility, improve the vibration resistance and liquefaction capacity of the foundation The purpose is to eliminate the collapsibility of the foundation in the collapsible foundation. This p...

Problems solved by technology

The winch system (mechanism) with large single-rope tension, high braking and clutch performance not only greatly increases the purchase cost, but also makes the control system very complicated.

In addition, the high working level of the dynamic tamping machine (frequent use, high full load force), the frequent impact generated can easily cause the failure of the hoisting mechanism and the fatigue damage of the wire rope, so the performance requirements for the hoisting mechanism and the wire rope are greatly improved
