A balance hook of a dynamic compaction machine and a balance hook mechanism having the same

Abstract

The invention relates to a dynamic compaction machinery balancing hook, comprising a base balancing beam, wherein a hook body of the hook is arranged at the lower part of the base balancing beam; the hook body of the hook is connected with the base balancing beam rotationally; a first and a second hoisting balancing beams are arranged at two ends of the base balancing beam respectively; the first and the second hoisting balancing beams are respectively connected with the base balancing beam by pin rolls rotationally. According to the invention, a defect of low efficiency of the traditional dynamic compaction machinery is overcome; with the adoption of a work process of pulley block backward-acting and a structure with two cooperative balancing beams, and under the condition of assuring a hoisting capability and by using a method of great force but distance saving, the work efficiency of the dynamic compaction machinery is improved. The dynamic compaction machinery balancing hook disclosed by the invention also overcomes technical problems of steel wire rope length deviation, non-uniform hook stress, unbalance pounder stress and the like.

Description

technical field [0001] The invention relates to a suspension hook of a dynamic tamping machine and a balance hook mechanism, in particular to a balance suspension hook of a dynamic tamping machine and a balance hook mechanism provided with the suspension hook. Background technique [0002] The dynamic tamping machine uses the high impact energy generated by the high drop of the heavy hammer to forcefully squeeze crushed stones, flakes, slag and other materials with better performance into the foundation, and form one by one granular pier in the foundation. The soil between the piers forms a composite foundation to increase the bearing capacity of the foundation, thereby reducing the settlement of the foundation. [0003] When the dynamic tamping machine is working, first use the lifting equipment to repeatedly lift the load of 20 tons to 40 tons or the hammer to a high place, and then use the automatic decoupling to release the load or the hammer to make it fall freely. The...

Problems solved by technology

[0008] Therefore, the disadvantage of the prior art is that: during the operation of the dynamic tamping machine, it is necessary to frequently and repeatedly lift the hook of the rammer to a certain height, and perform the decoupling and falling operation

If we want to improve the efficiency of dynamic compaction, we can only increase the lifting speed, and the lifting speed is directly proportional to the working speed of the winch, and inversely proportional to the multiplier of the pulley block; however, due to the objective limitation of the winch speed, the current The rising time of the rammer in the existing technology is far from meeting the needs of users
