Self mounting and dismounting method of balance weight of dynamic compactor and strut for same

Abstract

The invention provides a self mounting and dismounting method of a balance weight of a dynamic compactor. A mounting method of the balance weight includes the following steps of releasing a luffing steel wire rope which is wound on a luffing winch, enabling a hoisting steel wire rope of a quick-release winch to wind the rear portion of a strut and to be connected with the balance weight, coiling the hoist steel wire rope of the quick-release winch, tightening up the luffing steel wire rope of the luffing winch at the same time, and connecting the balance weight and a mounting frame. A dismounting method of the balance weight includes the following steps of enabling the hoisting steel wire rope of the quick-release winch to wind the rear portion of the strut and to be connected with the balance weight, tightening up the hoisting steel wire rope of the quick-release winch, eliminating connecting between the balance weight and the mounting frame, releasing the hoisting steel wire rope, releasing the luffing steel wire rope at the same time in order to enable the balance weight to be far away from the mounting frame arranged at the rear portion of a rotary table, eliminating connecting between the hoisting steel wire rope and the balance weight, and finishing dismounting of the balance weight of the dynamic compactor. Therefore, the mounting and dismounting of the balance weight of the dynamic compactor are achieved under the condition that no help of other auxiliary equipment exists. The invention further provides the strut for the self mounting and dismounting method. The strut comprises two supporting rods which are arranged in parallel, and a hoisting fixed pulley is arranged at the rear portion of each supporting rod. Therefore, abrasion, caused by the strut, of steel wire ropes is reduced when the strut is used.

Description

technical field [0001] The invention relates to a method for self-disassembling and assembling the counterweight of a dynamic tamping machine; the invention also relates to a special pressing bar for the self-disassembling and assembling method for the counterweight of a dynamic tamping machine. Background technique [0002] The dynamic compaction machine is widely used in the field of construction engineering. It uses the high impact energy generated by the high drop of the heavy hammer on the dynamic compaction machine to forcefully squeeze gravel, flakes, slag and other materials with better performance into the foundation. The concrete pier is formed one by one, and the soil between the pier and the pier forms a composite foundation to improve the bearing capacity of the foundation and reduce settlement. [0003] Such as figure 1 As shown, the common dynamic compaction machine in the market is a crawler type dynamic compaction machine, including a crawler device at the ...

Problems solved by technology

[0007] In order to prevent the dynamic compaction machine from tipping over during operation, the mounting frame 9 at the rear of the turntable 1 is equipped with a counterweight 8 to achieve the purpose of balancing the entire dynamic compaction machine. In order to facilitate the purpose of normal transportation, the counterweight 8 must be removed during transportation. However, the mass and volume of the counterweight 8 are very large, and it must be installed or disassembled with a separate counterweight removal device other than the dynamic compaction machine.

[0008] At present, the self-disassembly and assembly method of the counterweight of the dynamic compaction machine is generally used to complete the loading and unloading of the counterweight by cooperating with the counterweight disassembly device. Generally, the method of disassembling and disassembling the counterweight by using the top extension of the oil cylinder, or using the lifting pull plate to disassemble and assemble the weight method, must add a lot of equipment, difficult to operate, inconvenient to transport and increase the cost more
