Problems solved by technology

The tamping device is one of the commonly used construction machinery. The existing tamping device cannot compact the tamped subgrade, which makes the subgrade's ability to resist dynamic loads weak. The ability to resist the invasion and destruction of climate, earthquake and other natural conditions is weak, and it does not have enough firmness, stability and durability. It cannot use the rear output of the tractor to drive the tamping device to complete the tamping task. Therefore, a Tamping devices for road construction

Abstract

The invention discloses a tamping device for road engineering. The tamping device comprises a bottom plate, wherein a hydraulic oil tank, an oil pump, a speed reducer and a hydraulic distributor are arranged at the upper part of the bottom plate; an output shaft of the speed reducer is fixedly connected with an input shaft of the oil pump; an oil inlet of the oil pump is communicated with an oil outlet of the hydraulic oil tank through a hydraulic pipe; in addition, an oil outlet of the oil pump is communicated with an oil inlet of the hydraulic distributor through a hydraulic pipe; one side of the bottom of the bottom plate is provided with a press roller through a support frame; the other side of the bottom of the bottom plate is provided with a support wheel through a vibration reduction support frame. The tamped roadbed can be compressed, so that the dynamic load resistance capability of the roadbed is high; the resistance capability for resisting the damage and invasion caused bythe natural condition change such as geology, water, rainfall, climate and earthquake is high; the enough firmness, stability and durability are realized; the back output of a tractor can be used fordriving the tamping device to complete the tamping task; the tamping device is worthy of being popularized and generalized.

Description

technical field [0001] The invention relates to the technical field of construction machinery equipment, in particular to a tamping device for road construction. Background technique [0002] Construction machinery is an important part of the equipment industry. In a nutshell, all the mechanical equipment necessary for comprehensive mechanized construction projects required for earthwork construction projects, road surface construction and maintenance, mobile lifting and loading and unloading operations, and various construction projects are called construction machinery. The tamping device is one of the commonly used construction machinery. The existing tamping device cannot compact the tamped subgrade, which makes the subgrade's ability to resist dynamic loads weak. The ability to resist the invasion and destruction of climate, earthquake and other natural conditions is weak, and it does not have enough firmness, stability and durability. It cannot use the rear output of ...
