Grabbing device and working method thereof for earthwork engineering construction

Abstract

The invention discloses a grabbing device for earthwork engineering construction and a working method thereof. The grabbing device includes a frame bottom plate and a mounting plate. The two mounting plates are rectangular parallelepiped and arranged symmetrically. The frame bottom plate is symmetrically arranged on both sides of the bottom of the mounting plate. A reinforced connection mechanism is provided above the mounting plate; the piston rod of the cylindrical cylinder block is connected with a rotating plate passing through the waist-shaped hole through a hinge, and a through hole is opened at the bottom of the rotating plate, and the through hole is interference fit with a rotating shaft. Both ends are fixedly connected with a grabbing mechanism; the grabbing mechanism includes a melon-grabbing swing arm, a melon-grabbing connecting plate, and a melon-grabbing swing arm. The melon-grabbing connecting plate is welded, and the melon-grabbing connecting plate is in the shape of a rectangular plate, and the inner side of the melon-grabbing connecting plate is threadedly connected with several parallel-arranged melons. Working methods include sampling operations and grabbing operations. The grasping device of the present invention has high flexibility, convenient operation, high safety and the function of sampling.

Description

technical field [0001] The invention relates to the field of building engineering construction devices, in particular to a grabbing device for earthwork construction and a working method thereof. Background technique [0002] Earthwork is one of the main types of engineering in construction engineering, including excavation, filling, transportation, drainage, and precipitation of all earthworks. The amount of earthwork is large, the construction conditions are complex, and it is greatly affected by geological, hydrological, meteorological and other conditions. [0003] The prior art (CN205116258U) discloses a new type of stone picker, the upper mount is fastened to the top of the connection base, and a rotary mechanism is socketed between the upper mount and the connection base; two ear plates The tops of the positioning plates are respectively fastened to the left and right sides of the bottom surface of the transverse seat plate, a pair of parallel first pins are arranged...

AI Technical Summary

Problems solved by technology

[0004] In the existing earthwork construction process, the grabbing device used for soil blocks and rocks has the following technical problems: (1) The installation space is large, the installation cost is high, and the grabbing mechanism has low gripping flexibility and inconvenient operation; (2) Due to the large gravity during the grabbing operation, it is easy to shake, and the impact of the grabbing melon on the soil and rocks is large, and the safety of the grabbing operation is low; (3) It does not have the relevant structure and function of sampling.
