Subgrade ramming device

Abstract

The invention relates to a subgrade ramming device which comprises a supporting rod. Storage boxes are symmetrically arranged at the two ends of the supporting rod. Two supporting plates are symmetrically arranged below the supporting rod. Each supporting plate is provided with a first hydraulic device. The lower end of each supporting plate is connected with a rolling wheel. The upper end of each first hydraulic device is connected with a first hydraulic telescopic rod. Each first hydraulic telescopic rod is in sliding connection with the corresponding supporting plate. A second hydraulic device is arranged between the two first hydraulic telescopic rods and is in sliding connection with the supporting rod. The lower portion of the second hydraulic device is connected with a second hydraulic telescopic rod. The lower portion of the second hydraulic telescopic rod is detachably connected with a pressure block through a shaft sleeve. A plurality of grooves are symmetrically formed in the pressure block. The opening positions of the grooves are connected with cover plate capable of being opened. The subgrade ramming device is high in automation degree, good in flexibility and capable of adjusting the ramming pressure according to ramming requirements.

Description

Technical field [0001] The invention relates to a tamping device, in particular to a roadbed tamping device. Background technique [0002] Tamper refers to a machine used for tamping. It is mostly used to level and compact the foundation during construction. [0003] Rammers are classified into thermal rammers, electric frog rammers, and rapid impact rammers. [0004] Thermal ram: It is made according to the principle of a two-stroke internal combustion engine. There are two pistons in the cylinder, the upper piston is the internal combustion piston, and the lower piston is the buffer piston. The lower part of the cylinder is fitted with a rammer with an inclined bottom surface, so that the vertical axis of the cylinder is inclined forward. The upper piston rod protrudes from the through hole in the middle of the cylinder head cover, and the lower piston rod protrudes from the lower end of the cylinder and is integrated with the rammer. The cylinder and the rammer are tensioned by...

Problems solved by technology

[0010] 3. The tamping machine shall not be rammed on frozen soil, solid stone, broken brick and stone mixed soil. When the tamping machine turns, it shall not turn sharply and let it walk freely without support. No one is allowed inside. When multiple rammers are ramming, the left-right distance shall not be less than 5m, and the front-to-back distance shall not be less than 10m. Operators must wear insulated shoes and insulated gloves

However, this kind of tamping and compacting device has poor flexibility, and the tamping weight cannot be adjusted.
