Decoupling test device of dynamic compaction machine

Abstract

The invention discloses an unhooking test device of a dynamic compactor. The unhooking test device comprises an oil tank, an overflow valve, a fixed base and a load cylinder, wherein the load cylinder is arranged on the fixed base and communicates with the oil tank; a piston telescopic section of the load cylinder is provided with a hook device for connecting with an unhooking device; the load cylinder is provided with a first cavity and a second cavity; a piston rod of the load cylinder is positioned in the first cavity; a one-way valve is arranged between the oil tank and the first cavity in a direction that liquid flows from the oil tank to the first cavity; and one end of the overflow valve is connected with the oil tank, and the other end of the overflow valve is connected with a pipeline between the one-way valve and the first cavity. By setting the devices including the load cylinder, the oil tank, the overflow valve and the fixed base, the quality of the compactor can be simulated, a case that the use of the compactor generates influence on a place and a surrounding environment can be effectively avoided, and then workers can perform an unhooking test on the compactor on the spot, so that the unhooking test device provided by the invention is convenient for the workers to perform a test on the compactor.

Description

technical field [0001] The invention relates to the technical field of engineering machinery, in particular to a decoupling test device for a dynamic compaction machine. Background technique [0002] The dynamic tamping machine is a kind of construction machinery equipment that lifts the rammer to a specified height by hoisting and unhooking it so that the rammer falls freely and rams the ground to compact the ground. Wherein, the uncoupling device is used for hoisting the rammer, and when the specified height is reached, the device of the hoisting rammer can be loosened by pulling the decoupling wire rope. The rammer is a heavy hammer used for ramming the ground. It is manufactured by welding or casting. Different models of dynamic ramming machines use rammers of different weights. [0003] Due to the harsh working conditions of the dynamic compaction machine, the working reliability of the dynamic compactor is an important indicator. It is necessary to test the performanc...

AI Technical Summary

Problems solved by technology

When carrying out the performance test of the dynamic compaction machine, if the test is carried out in the field, since the rammer is in contact with the ground during the compaction, the vibration and noise are very large, which is very destructive to the surrounding residents and the test field.

If it is used on the construction site, due to the stable position of the dynamic compaction machine, there will be problems during the use process, which will easily delay the construction, and it will need to invest a lot of manpower and material resources, and the cycle will be longer.
