Novel hydraulic excavator piling device

Abstract

The invention discloses a novel hydraulic excavator piling device. The novel hydraulic excavator piling device structurally comprises an external connecting frame, a fixing screw and a piling mechanism; the fixing screw is connected to an internal thread of the external connecting frame, and the piling mechanism penetrates through the internal position of the external connecting frame; when a lower pressure rod descends, reverse thrust is generated by the bottom of a soil pile pit on two outer expansion plates, and the external expansion plates can slide and unfold outwards along a connecting frame so that the sides of the external expansion plates can compact the inner wall of the soil pile pit, thus the phenomenon that soil on the inner wall of the soil pile pit falls off when a lower pressing rod is completely pulled out is avoided, and the situation that soil on the inner wall of the soil pile pit containing much sand is prone to falling off is effectively avoided; and the inner wall of the soil pile pit extrudes the position between two sliding plates, the sliding plates can slide towards the two sides along a rear frame, therefore the sliding plates can flatten and compact the inner wall of the soil pile pit, and therefore, the lower pressing rod can be easily pulled out of the interior of the soil pile pit.

Description

technical field [0001] The invention relates to the field of hydraulic pressure and its equipment, in particular to a novel hydraulic excavator piling device. Background technique [0002] The hydraulic excavator piling column is mainly used for piling the land. By installing the hydraulic excavator piling column on the front end of the hydraulic excavator, the hydraulic rod on the hydraulic excavator piling column pushes the pressure rod down into the land. , after the pressure rod drops to the required depth, the pressure rod is pulled up by the hydraulic rod, so that the pressure rod can take the soil inside the soil pile hole out, so the soil pile hole of the required depth can be obtained, based on The above description The inventors found that the existing piling device for a new hydraulic excavator mainly has the following deficiencies, for example: [0003] Because part of the land contains a lot of sand, the soil inside the land will be relatively loose, and the hy...

Problems solved by technology

[0003] Because part of the land contains a lot of sand, the soil inside the land will be relatively loose, and the hydraulic excavator piles the land vertically, so that when the hydraulic excavator vertically extends upwards, it is easy The loose soil on the inner wall of the pile pit will fall, causing the actual depth of the pile pit to be smaller than the required depth
