Abstract
The utility model discloses a sleeve for mine underground bolting installation, including swing joint's hollow column sleeve head and sleeve rod portion, wherein, sleeve rod portion is provided with extension portion and sleeve afterbody, the one end and the sleeve head swing joint of extension portion, the other end and sleeve afterbody swing joint, the inner wall of the one end of sleeve head is provided with the fastener that is used for spacing anchor bolt to strut, the beneficial effects of the utility model are that: the length of the sleeve for installing the anchor rod support is increased, so that when the anchor rod is installed in a mine roadway, a climbing tool is not needed, the sleeve for installing the anchor rod support under the mine can be directly adopted for installation, time and labor are saved, and casualties possibly caused in the installation process are reduced.
Description
Technical Field
The utility model belongs to the technical field of the stock drilling equipment, more specifically say, the utility model relates to a sleeve that is used for mine underground anchor bolt to strut installation.
Background
Present colliery mine is multi-purpose stock in pit consolidates the tunnel, strut, carry out the in-process of installing to the stock in the mine tunnel, along with the section crescent in tunnel under the frame, the height in tunnel also increases gradually, lead to receiving the hindrance at the stock at the in-process of installation, the tunnel height is too high, installation stock fastening screw also becomes more difficult, take trouble and difficultly, moreover, need carry out work with the help of climbing tool during the installation stock, tunnel ground unevenness leads to the in-process climbing tool of stock installation to turn on one's side very probably, cause the casualties.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a solve the mine tunnel height and lead to the obstructed sleeve that is used for mine underground bolting to strut installation of stock installation too high.
In order to realize the purpose, the utility model discloses the technical scheme who takes does:
the utility model discloses a sleeve for installation is strutted to mine underground stock, including the hollow column sleeve head and the sleeve pole portion of rigid coupling in proper order, sleeve pole portion includes the extension portion and the sleeve afterbody of rigid coupling, the one end welding sleeve head of extension portion, other end welding sleeve afterbody.
The utility model discloses a sleeve for installation of mine underground bolting, hollow column sleeve head and sleeve rod portion including swing joint, wherein, sleeve rod portion is provided with extension portion and sleeve afterbody, the one end and the sleeve head swing joint of extension portion, the other end and sleeve afterbody swing joint.
The utility model discloses a sleeve for mine underground bolting installation, the inner wall of the one end of sleeve head is provided with the fastener that is used for spacing anchor bolt to strut, and the other end is provided with the external screw thread.
The utility model discloses a sleeve for installation is strutted to mine underground stock, the one end of extension portion be provided with the corresponding internal thread of the external screw thread that sleeve head set up, the other end is provided with the external screw thread, sleeve head and extension portion threaded connection.
The utility model discloses a sleeve for installation is strutted to mine underground stock, the one end of sleeve afterbody be provided with the corresponding internal thread of extension portion external screw thread, extension portion and sleeve afterbody threaded connection.
Adopt the technical scheme disclosed in the utility model, adopt threaded connection extension portion between sleeve head and sleeve afterbody, can install at any time and dismantle, can highly change the extension portion that length is different according to the mine tunnel of difference, and easy operation is nimble, utilize manifold cycles, moreover, the telescopic length of installation stock support has been increased, when making in the mine tunnel install the stock, needn't borrow the climbing tool, directly adopt the mine down the sleeve of stock support installation just can install, time saving and labor saving, the casualties that probably causes in the installation has also been reduced simultaneously.
