Problems solved by technology

[0002] In the prior art, the bolt used by the drilling rig, especially the bolter, has no supporting protection and guiding structure on the upper part, which makes the bolt easy to swing and unbalanced load during transmission, which makes the drilling rig suffer from excessive load; at the same time, due to the The working environment is harsh, and the dust-proof problem has become the main factor affecting the service life of the rock bolter. The traditional dust-proof method adopts to increase the accuracy and quality of the sealing performance, but this method will still cause the bearing to burn out and the drive shaft to be damaged, thereby shortening the life of the drilling rig. service life

Embodiment Construction

[0010] The drilling rig of the present invention uses an automatic locking centering mechanism, such as figure 1 , figure 2 As shown, there are two mutually perpendicular cracks at the upper end of the anchor sleeve 1 of the drilling rig, the locking handle 2 is arranged on the periphery of the anchor sleeve 1, the end is provided with a locking shaft 2, and the adjusting bolt 3 is arranged on the anchor At the vertical crack of the rod sleeve 1, its end face is in contact with the locking shaft 7. When the hydraulic motor drives the anchor rod sleeve 1 to rotate, the moment of inertia generated locks the anchor rod, and the hexagonal guide sleeve 4 is set in the anchor rod sleeve 1. The upper part of the anchor can be supported, protected and guided. The anchor sleeve 1 is connected and installed on the bearing seat 8 through the self-aligning bearing 5. The bearing seat 8 is coaxial with the anchor sleeve 1 and has a certain Clearance, the dustproof ring 9 is located under...

Abstract

The invention relates to an automatic locked centering dustproof mechanism for a drilling machine. According to the structure of the automatic locked centering dustproof mechanism, two cracks which are perpendicular to each other are formed in the upper end of an anchor rod sleeve of the drilling machine; an automatic locked centering device is arranged at the vertical crack of the anchor rod sleeve; a hexagon guide sleeve is arranged inside the anchor rod sleeve; the anchor rod sleeve is mounted on a bearing seat through a centering bearing in a linked manner; a dustproof ring is arranged below the centering bearing and is fixed on the anchor rod sleeve; the bearing seat is fixed on the upper end cover of the drilling machine. The automatic locked centering dustproof mechanism has functions of automatic locking, centering, dust prevention and the like, and the service life of the drilling machine can be prolonged.

Description

technical field [0001] The invention relates to a drilling machine used in mines and buildings, in particular to an automatic locking, self-aligning, dust-proof mechanism for the drilling machine. Background technique [0002] In the prior art, the bolt used by the drilling rig, especially the bolter, has no supporting protection and guiding structure on the upper part, which makes the bolt easy to swing during transmission and unbalanced load, so that the load on the drilling rig is too large; at the same time, due to the The working environment is harsh, and the dust-proof problem has become the main factor affecting the service life of the rock bolter. The traditional dust-proof method adopts to increase the accuracy and quality of the sealing performance, but this method will still cause the bearing to burn out and the drive shaft to be damaged, thereby shortening the life of the drilling rig. service life. Contents of the invention [0003] The purpose of t...
