Problems solved by technology

[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 excavation tools and construction methods are difficult to construct
In recent years, full-casing full-rotary drilling rigs have appeared at home and abroad, which is a new type of pile engineering machinery. However, the pin shaft connected to the oil cylinder on the machine has a backward lubrication method, which seriously reduces the service life of the pin shaft.
[0003] When the pin shaft of the prior art is constructed under high-strength conditions, this defect seems to be particularly prominent

Embodiment Construction

[0015] A pin shaft for a full-casing full-rotation drilling rig includes a flange 1, a shaft body 2, lubricating holes (3, 4), and a grease nipple 5. The flange 1 and the shaft body 2 are welded, and then connected to the oil cylinder through the hole on the flange 1, the lubricating hole 3 and the lubricating hole 4 penetrate each other, and the lubricating tool adds lubricant to the shaft through the grease nipple 5 to lubricate The material reaches the surface of the shaft 2 through the lubricating hole 3 and the lubricating hole 4, thereby lubricating the shaft 2 and connecting the oil cylinder.

[0016] In order to further improve the lubricating effect, the number of lubricating holes can be two, three or more. When there are two lubricating holes, the two lubricating holes are arranged symmetrically on the shaft body. When there are three lubricating holes, the three lubricating holes can be located on the same circumferential surface and distributed evenly, and the in...

Abstract

The invention relates to a hinge pin for a full-bushing full-slewing drilling machine. The hinge pin comprises a flange plate and a shaft body fixedly connected with the flange plate, wherein the shaft body is internally provided with a plurality of lubrication holes which are communicated with each other. According to the hinge pin for the full-bushing full-slewing drilling machine, a lubricant is added into the shaft body by utilizing grease nozzles through the lubrication holes in the shaft body, so that the aim of lubricating the hinge pin can be achieved.

Description

technical field [0001] The invention relates to a pin shaft, in particular to a pin shaft for 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, which is a new type of pile engineering machinery. However, the pin shaft connected to the oil cylinder on the machine has a backward lubrication method, which seriously reduces the service life of the pin shaft. [0003] When the pin shaft of the prio...
