Embodiment Construction

[0025] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] The main components of a long-stroke feeding mechanism for a mechanical power head include: a universal joint 19, a gear box, a transmission shaft assembly 10, a drill pipe 11, a hydraulic chuck 12, a power head 13, a carriage for the power head, and a cylinder Roller bolt type rollers, slide rails.

[0027] The slide rail is welded and installed on the lower tower body, the power head is fixed on the power head carriage, the cylindrical roller bolt type roller is installed on the power head carriage with bolts, and the power head carriage is fixed and installed on the bore of the feed oil cylinder through the fixing sleeve bracket. In the upper proper position, the power head carriage moves up and down on the guide rail slideway of the lower tower body by means of the cylindrical roller bolt type rol...

Abstract

The invention discloses a mechanical power head long stroke feeding mechanism and an operation method thereof. The mechanical power head long stroke feeding mechanism comprises a drilling rig rack, amotor, a clutch, a gearbox, an oil pump, a winch, a water brake device, a winch rack, a sleeve roller chain, a hexagonal vertical shaft, a drill rod, a hydraulic chuck, a power head, an arc tooth box,a first universal coupling, a first pneumatic clutch, a transfer case, a second pneumatic clutch and a second universal coupling. The invention further discloses the operation method for the mechanical power head long stroke feeding mechanism. For the mechanical power head long stroke feeding mechanism disclosed by the invention, by adopting the mechanical power head, the power transmission efficiency is high with high efficiency and energy conservation; by adopting a mechanical power head double-oil cylinder long stroke feeding device, a feeding stroke reaches 3.33 meters, and a core can betaken after primary feeding; and a power head sliding frame adopts a rolling wheel structure, and sliding friction is changed into rolling friction, so that rail abrasion is reduced, the running resistance is lowered, and in addition, maintenance and replacement are facilitated.

Description

technical field [0001] The invention belongs to the technical field of geological exploration, and relates to a long-stroke feeding mechanism of a mechanical power head and an operation method thereof. Background technique [0002] With the increase in the number of exploration cores and in-situ leaching process holes in the nuclear industry, the diameter of the exploration and construction apertures has increased, and the drilling has become deeper. usage requirements. [0003] In order to effectively save auxiliary working time and improve work efficiency, in the prior art, there is an urgent need for a long-stroke feeding mechanism of a mechanical power head and an operation method thereof. Contents of the invention [0004] In order to overcome the defects in the prior art, the present invention provides a long-stroke feeding mechanism of a mechanical power head and an operation method thereof. The mechanical power head has high power transmission efficiency, high ef...
