Abstract
The invention discloses a kind of front canopy hoisting ring, including hanging connecting portion, hanging ring, fastening bolt, described hanging connecting portion side is provided with the anchor nut matched with roofbolt, anchor nut uses with hanging connecting portion and is made of welded connection, described hanging ring one end is provided with and hangs connecting portion and be connected the nut matched, hanging ring one end is provided with the nut matched with fastening bolt, with hanging connecting portion is connected the nut matched and be connected with fastening bolt the nut matched respectively with hanging ring employing be welded to connect.Hanging ring uses specification width to be the steel pipe that 3cm and thickness are not less than 6 cun, is provided with one and may be used for the hole through fastening bolt, be provided with and be connected the nut matched with fastening bolt below hole below steel pipe.This front canopy hoisting ring laterally hangs on the roof timbering anchor pole at rear of meeting head on, it is to avoid move repeatedly forestope because making roofbolt, significantly reduces the labor intensity of worker.
Description
Technical field
The present invention relates to underground coal mine driving supporting field, be specifically related to a kind of front canopy hoisting ring.
Background technology
Underground coal mine boring head gib now uses the mode of front-probe support, and forestope typically uses the side of hanging
On the formula hanging roof timbering anchor pole that supporting is intact after meeting head on, but permanent support in the wings directly hung by existing erecting by overhang
Anchor pole on, due to former front canopy hoisting ring fixing after, forestope centrage with anchor pole point-blank, move and put in place by forestope
After, delay anchor pole of constructing of meeting head on, it is therefore desirable to anchor pole of constructing after intersection reach forestope, the most not only affect labor efficiency, with
Time there is also potential safety hazard.
Summary of the invention
It is an object of the invention to provide a kind of front canopy hoisting ring, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the present invention provides following technical scheme: one hangs connecting portion, hanging ring, fastening bolt,
Described hanging connecting portion side is provided with the anchor nut matched with roofbolt, and anchor nut uses with hanging connecting portion and welds
Being formed by connecting, described hanging ring one end is provided with and hangs connecting portion and be connected the nut matched, and hanging ring one end is provided with and fastens
The nut that bolt matches, is connected the nut matched and is connected the nut matched with fastening bolt respectively with hanging connecting portion
Use with hanging ring and be welded to connect.
Preferably, described hanging ring uses specification width to be 3cm, and thickness is not less than, and the steel pipe of 6 cun, below steel pipe
It is provided with one and may be used for the hole through fastening bolt, be provided with below hole and be connected the nut matched with fastening bolt.
Preferably, described hanging connecting portion and fastening bolt all use the screw-thread steel of Φ 18mm, and the nut on hanging ring is equal
And between the screw-thread steel of Φ 18mm, coupling is connected, and fastening bolt one end is provided with nut, weld between the screw-thread steel of nut and Φ 18mm
Connect in succession.
Compared with prior art, the invention has the beneficial effects as follows: this front canopy hoisting ring solves when visiting beam before use, faces
Time supporting after affect roofbolt by line construction problem；When gib can solid top board, meet the safety of gib
Requirement；Forestope can be made easy to use, reduce labor intensity during librarian use forestope gib；This forestope hangs
Hang device simple in construction, be prone to processing, there is higher promotional value.
Accompanying drawing explanation
Fig. 1 is that the present invention assembles front schematic diagram.
Fig. 2 is schematic diagram after the present invention assembles.
In figure: 1-hangs connecting portion, 2-hanging ring, 3-fastening bolt.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Describe, it is clear that described embodiment is only a part of embodiment of the present invention rather than whole embodiments wholely.Based on
