Problems solved by technology

However, due to the multi-head claws used in the existing full-casing full-rotary drilling rig, the tension force is small, the neutrality is poor, and the disassembly and assembly are inconvenient, etc., which affect the construction progress. Faults such as crushing or insufficient excavation force lead to slow construction progress, casing damage and even waste piles

Abstract

The invention discloses a multi-head gripper for a full-sleeve full-rotation drill and belongs to engineering machinery. The multi-head gripper comprises a steel wire rope connector, a rotary connecting component, a core shaft, a connecting sleeve, an upper connecting device, a lower connecting device, brake shoe components and a parallelogram four-connecting rod structure for connecting the lower connecting device and the brake shoe components. The lower end of the steel wire rope connector is connected with the connecting sleeve through the rotary connecting component; and the connecting sleeve is sleeved on an outer sleeve and is fixed with the outer sleeve through a pin shaft III. The upper connecting device is fixed on the outer sleeve; and the lower end of the connecting sleeve is connected with the lower connecting sleeve. The number of the brake shoe components is three groups; the upper ends of the brake shoe components are connected with the upper connecting device through driving rods, and the middle lower parts of the brake shoe components are connected with the lower connecting device through the parallelogram four-connecting rod structure; a flange plate is arranged at the lower end of the lower connecting device; and an auger is installed on the flange plate. During the work, arc-shaped plates on the brake shoe components are tightly attached with the sleeve of the drill to obtain the power.

Description

technical field [0001] The invention relates to an earthwork engineering machine, in particular to a multi-head claw used on a full-casing full-rotation drilling machine. Background technique [0002] With the continuous acceleration of my country's infrastructure construction, more and more constructions are being carried out in various complex geological environments such as plateaus, mountains, hills, beaches, rivers, lakes and tidal flats. During on-site construction, quicksand, karst caves, rock formations, etc. are often encountered underground. Various complex geological conditions, traditional excavating tools and construction methods are difficult to construct. In recent years, full-casing full-rotary drilling rigs have appeared at home and abroad. This machine has the characteristics of high efficiency, high quality, and environmental protection. However, due to the multi-head claws used in the existing full-casing full-rotary drilling rig, the tension force is sma...
