Abstract
The utility model discloses a slurry prevention power head used for a rotary drilling rig; a dustproof device is added between a power head speed reducing box and a power head damping device; the dustproof device comprises a dustproof ring seat, a dustproof ring and a dustproof inner ring; the dustproof inner ring in the dustproof device is connected and fixed with a bearing end cover in the power head damping device by a hexagonal bolt; and the dustproof ring seat and the dustproof device are connected with a sleeve by an inside hexagonal bolt and rotate along the sleeve. As the dustproof device is added, the slurry prevention power head is simple in structure, and slurry can be effectively prevented from entering into the power head.
Description
Technical field
The utility model relates to a kind of unit head, particularly relates to a kind of unit head of rotary drilling rig.
Background technology
At present, China's rotary drilling rig extensive use in pile foundation construction.Unit head is the key working part of rotary drilling rig, and can unit head operate as normal directly have influence on the efficiency of construction of rotary drilling rig.In the rotary drilling rig work progress,, cause mud to enter the phenomenon ubiquity of unit head now, cause construction party to need irregularly to clean and change the unit head gear oil, influence efficiency of construction owing to tight inadequately to the safeguard procedures of unit head.
Summary of the invention
The purpose of this utility model is to provide a kind of has increased dust guard on original unit head basis, this device can not only prevent effectively that mud from entering unit head, and device is simple, easy to manufacture, and it is convenient to change.
Technical solution of the present utility model is such: a kind of anti-mud unit head, comprise platen, reduction box, dust guard, damping device, protect frame, motor and balladeur train, it is characterized in that between unit head reduction box and the damping device dust guard being arranged, dust guard has dustproof ring support, dust ring, dustproof inner ring.
The dustproof inner ring of dust guard connects with bearing (ball) cover in the unit head reduction box by hex bolts.
Dustproof ring support and damping device connect with sleeve by hexagon socket head cap screw.
The utility model has the advantages that: between the reduction box of unit head and unit head damping device, increased dust guard, in the process on probation, obvious on rotary drilling rig to the obstruction effect of mud, solved the problem that unit head advances mud.
Description of drawings
It is such that structure of the present utility model constitutes:
Fig. 1 installs assembling front view for the utility model overall structure.
Fig. 2 is a dust guard sectional structural map of the present utility model.
Fig. 3 is that technique of painting figure is amplified in the part of I among Fig. 2.
Among Fig. 1～Fig. 3, platen (1), reduction box (2), dust guard (3), damping device (4), protect frame (5), motor (6), balladeur train (7), dustproof ring support (8), dust ring (9), dustproof inner ring (10), sleeve (11), bearing (ball) cover (12), hexagon socket head cap screw (13), hex bolts (14).
The specific embodiment
Most preferred embodiment of the present utility model is such, with reference to accompanying drawing 1～Fig. 3, between unit head reduction box (2) and the damping device (4) dust guard (3) is housed, and dust guard (3) is equipped with dustproof ring support (8), dust ring (9), dustproof inner ring (10).Dustproof inner ring (10) in the dust guard (3) connects with bearing (ball) cover (12) in the unit head reduction box (2) by hex bolts (14) to be fixed, dustproof ring support (8) and damping device (4) connect with sleeve (11) by hexagon socket head cap screw (3), with its rotation.Because mud is to infiltrate unit head by the bearing (ball) cover of unit head reduction box (2) (12) and the gap of sleeve (11).After increasing dust guard (3), when mud along unit head damping device (4) when flowing down, mud flows down along dustproof ring support (8), falls on the dustproof inner ring (10), outside the inner ring (8) that prevent dust is blocked in, upwards spatters as if mud, is then stopped to get off by dust ring (9).
Claims (3)
1. anti-mud unit head, comprise platen, reduction box, dust guard, damping device, protect frame, motor and balladeur train, it is characterized in that between unit head reduction box (2) and the damping device (4) dust guard (3) being arranged, dust guard (3) has dustproof ring support (8), dust ring (9), dustproof inner ring (10).
2. according to the described anti-mud unit head of claim 1, the dustproof inner ring (10) that it is characterized in that dust guard (3) connects with bearing (ball) cover (12) in the unit head reduction box (2) by hex bolts (14).
3. according to the described anti-mud unit head of claim 1, it is characterized in that dustproof ring support (8) and damping device (4) connect with sleeve (11) by hexagon socket head cap screw (13).
