Abstract
The utility model relates to a coal mine drilling device, in particular to a drilling buffering compression-resistant dustproof waterproof protective device for a power head in a drilling machine. The drilling buffering compression-resistant dustproof waterproof protective device for the power head comprises an installation flange installed on the front end face of the power head. An inner dustproof ring is arranged between the back face of the installation flange and the front end face of a box body of the power head, an umbrella-shaped outer dustproof ring is arranged on the front end face of the installation flange, and an inner hole of the outer dustproof ring is matched with a drilling rod of a drilling device in diameter. The outer dustproof ring is pressed tightly on the front end face of the installation flange through a pressing plate and a pressing screw which are connected to the installation flange. The drilling buffering compression-resistant dustproof waterproof protective device for the power head can effectively protect the power head and is good in dustproof effect and waterproof effect.
Description
Technical field
The utility model relates to a kind of colliery drilling equipment, specifically a kind of buffering of the probing for rig resistance to compression dustproof and waterproof unit head protective device.
Background technology
The unit head of colliery drilling equipment is the power resources of rig, in drilling process, often will carry out the probing at the elevation angle, and angle can reach 90 °, is even greater than 90 °.In drive, during operation, often there is underground water, coal dust, the dropping or ooze out of rock.When beating the elevation angle, unit head leading portion is directly in the face of these unfavorable situations.Existing brill control equipment dynamic head is mainly realized by the sealing ring of main shaft the sealing of water, coal dust, but unit head when rotated seal very easily damage, the reliability of rotatory sealing is difficult to good solution always.The infiltration of water can cause getting rusty of functor, and the infiltration of coal dust causes coal dust to be piled into for a long time piece, causes the locking of rig or slips.The dropping directly also to pound of rock dropped on unit head leading portion, very easily damages the end cap of unit head.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of and can effectively protect unit head, the probing buffering resistance to compression dustproof and waterproof unit head protective device of dustproof and good water-proof effect.
Probing buffering resistance to compression dustproof and waterproof unit head protective device of the present utility model includes the mounting flange being arranged on unit head front end face, between the back side of mounting flange and unit head casing front end face, be provided with the interior dust ring of annular, mounting flange front end face is provided with the outer dust ring of umbrella, and the endoporus of outer dust ring matches with the drill pipe diameter that bores control equipment; Outer dust ring is by being connected on the front end face that pressing plate on mounting flange and housing screw be pressed on mounting flange.
On described mounting flange, be also connected with a stop screw, the end of stop screw is stretched out and extend in the annular guide channel of interior dust ring front end face from mounting flange rear end face, interior dust ring can freely be rotated relative to mounting flange, avoid producing friction with unit head casing front end face.
Described interior dust ring and outer dust ring are manufactured by elastomeric material.
Advantage applies of the present utility model exists: 1, utilize the water proofing property of dust ring outside umbrella, reach the infiltration of anti-sealing; The outward appearance of umbrella shape can be opposed at leading portion by coal dust, focuses on, and cleans impact force when available buffer rock drops simultaneously, unit head casing being produced; 2, utilize the elasticity of outer dust ring endoporus, when drilling rod is flexible, by the mud of drilling-rod external wall, coal dust is cleared up at unit head leading portion, prevents from entering into unit head inside by main shaft inner chamber; 3, this installs in unit head leading portion, thereby makes staff observe at any time the duty of this device when work, thereby has reduced maloperation, when having protected rig, has increased the safety of construction; .4, this apparatus structure is simple, and product difficulty of processing is little, easy for installation, is convenient to the installation and removal under ore deposit.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
As shown in the figure, this probing buffering resistance to compression dustproof and waterproof unit head protective device includes the mounting flange 2 being arranged on unit head 1 front end face, between the back side of mounting flange and unit head casing front end face, be provided with the interior dust ring 3 of annular, mounting flange front end face is provided with the outer dust ring 4 of umbrella, and the endoporus of outer dust ring 4 matches with the drill pipe diameter that bores control equipment; Outer dust ring 4 is pressed on the front end face of mounting flange 2 by the pressing plate 5 and the housing screw 6 that are connected on mounting flange.On described mounting flange 2, be also connected with a stop screw 7, the end of stop screw is stretched out and extend in the annular guide channel 8 of interior dust ring 3 front end faces from mounting flange 2 rear end faces, interior dust ring can freely be rotated relative to mounting flange, avoid producing friction with unit head casing front end face.Described interior dust ring 3 and outer dust ring 4 are manufactured by elastomeric material.
