Description

Special dust keeper of rock soil property site consolidates rig

Technical Field

The invention relates to a technology for protecting and reinforcing a rock-soil site, in particular to a special dustproof technology for a rock-soil site reinforcing drilling machine.

Background

The rock-soil site comprises the soil site and the stone site, is a treasure representing national culture art in a specific historical period deposited in ancient long years, belongs to non-renewable resources, and has extremely high historical value, scientific value and artistic value. Due to environmental changes, commercial corrosion, artificial damage and other factors, a large number of ancient sites have various diseases, such as stone etching crack development, stone image fracture, undercut, crack, collapse and the like of the soil site development. Aiming at the diseases of the rock-soil relics, the methods of anchor rods, reinforcement, grouting, drain holes and the like are widely applied to reinforcement of the ancient relics, and all the methods need to drill holes in the rock-soil relics. However, since the rock-soil site reinforcement areas are all tourist attractions, slag dust seriously damages the physical health of operators of drilling machine workers in the drilling process, influences the drilling quality, and also seriously influences the visit of the site due to the pollution to the surrounding environment. In recent years, a set of special dust-proof devices which are suitable for the rock-soil site protection engineering driller are formed through the practice of a large number of rock-soil site protection engineering.

The prior art relates to a dustproof device (CN 201410426522.8) of a drilling machine special for an earthen site, which mainly comprises a drill rod, a different-shaped cylinder, a first dustproof baffle, a second dustproof baffle, a first locking positioning bracket, a second locking positioning bracket, a locking positioning nut, a positioning bracket steel plate, a rigid and flexible device, a contact type flexible device, a drill bit, a dustproof closing-in, a slag hole, a slag bag and a rigid and flexible locking device. The contact type flexible device is close to the sealed front end of the drilling site body, the upper parts of the two second locking and positioning brackets are respectively used for fixing the positioning bracket steel plates through locking and positioning nuts, and the lower parts of the two first locking and positioning brackets are respectively used for fixing the opposite cylinders through the locking and positioning nuts; the special cylinder is provided with a rigid-flexible device and a contact-type flexible device at the end, a drill bit is connected with a drill rod in the special cylinder, a first dust-proof baffle and a second dust-proof baffle are arranged on the drill rod, the lower part of the special cylinder is communicated with a cylindrical slag outlet through a dust-proof closing-in, the slag outlet is provided with a rigid-flexible locking device, and slag is sleeved at the bottom. The technology is inconvenient to use and complex to install. Only two dustproof baffles are used, so that dust and slag cannot be effectively prevented, and especially the drill rod is more easily affected by a dustproof device when the drill rod is replaced.
