Technical Field
The utility model relates to a coal mine machinery, concretely relates to special tool to lock additional installation of anchor rope.
Background
In some places related to roadways such as in the pit of colliery, for the sake of safety, almost have one side the other and need use the anchor rope to consolidate the rock mass, and most anchor rope tool to lock is non-detachable after the installation, and after the anchor rope tool to lock was accomplished, anchor rope tool to lock plays the supporting role to the rock mass with the steel band of its top together, under the pressure of rock mass, anchor rope tool to lock can be locked with the anchor rope, and pressure is big more, and the anchor rope tool to lock is stronger with the effort of anchor rope to guarantee that the rock mass can not collapse.
However, in some coal mines, in order to improve the recovery rate and reduce the resource waste, when the coal mine passes through the coal mining working face, part of the anchor cable locks and the steel belts need to be removed to roof the coal seam, the anchor cables and the anchor cable locks have very strong toughness, the removal process is time-consuming and labor-consuming, part of the coal mines are removed by hollowing out the coal body above the anchor cable locks and removing the pressure near the anchor cable locks to remove the anchor cable locks, and the operation process is time-consuming and labor-consuming, thereby bringing great troubles to the production.
SUMMERY OF THE UTILITY MODEL
Aiming at the phenomenon that the anchor cable lock is time-consuming and labor-consuming to disassemble in the coal mining process, the additional device special for the anchor cable lock is provided.
In order to achieve the above object, the utility model provides a following technical scheme:
an anchor line-specific lock attachment comprising: the layer board, the backup pad, the arc recess, the screw, the bolt, the layer board becomes 90 degrees weldings with the backup pad, sets up the arc recess at the intermediate position of backup pad, and the effect of arc recess lies in increasing the area of contact with the anchor rope to increase frictional force, the arc recess runs through perpendicularly the layer board, sets up two screws in the backup pad, and the screw is symmetrical for the axis of arc recess.
The special lock for the anchor cable is used in pairs.
Compared with the prior art, the beneficial effects of the utility model are that:
the special tool to lock additional device of anchor rope structural design be reasonable, the preparation is simple and convenient, the practicality is strong, it is convenient to dismantle, and intensity and current anchor rope are different from each other, under the nervous condition of taking over in the pit digging for the anchor rope tool to lock dismantles and becomes high-efficient swift, labour saving and time saving is worth promoting and using in colliery machinery field.

Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Example 1
Referring to fig. 1, an embodiment 1 of the present invention is a schematic structural diagram of an additional device of a lock special for an anchor cable, including: layer board (4), backup pad (5), arc recess (6), screw (7), bolt (8), layer board (4) become 90 degrees weldings with backup pad (5), set up arc recess (6) in the intermediate position of backup pad (5), the effect of arc recess (6) lies in increasing the area of contact with anchor rope (1) to increase frictional force, arc recess (6) run through perpendicularly in layer board (4), set up two screw (7) on backup pad (5), screw (7) are symmetrical for the axis of arc recess (6).
The special lock for the anchor cable is used in pairs.
Example 2
Referring to fig. 2, embodiment 2 of the present invention is a schematic position diagram of an additional device of a lock dedicated for an anchor cable in the anchor cable, wherein a steel strip 2 is a steel plate with a through hole in the middle, a supporting plate 4 is parallel to the steel strip 2, a supporting plate 5 is perpendicular to the supporting plate 4, the supporting plate 5 mainly functions to transition the acting force of the steel strip 2 to an existing lock 3, and provides a spatial distance for slowing down the acting force on the existing lock 3 after the steel strip is disassembled.
Example 3
Referring to fig. 3, an embodiment 3 of the present invention is a top view of an attachment device for a special lock of an anchor cable,
the figure shows the relative position of an anchor line specific lock attachment in the bolt.
Example 4
Referring to fig. 4, embodiment 4 of the present invention is a schematic diagram of a disassembly state of an additional device of a lock dedicated for an anchor cable, after disassembling a bolt 8, a supporting plate 4 and a supporting plate 5 become a free state, then the supporting plate 4 and the supporting plate 5 are disassembled, a certain spatial distance is generated between a steel belt 2 and a current lock 3, the current lock 3 loses pressure, and the steel belt is easily disassembled in a loose state, so that the steel belt is also disassembled therewith, thereby completing the coal seam caving.
The embodiment of the utility model provides a theory of operation is:
after the steel belt is installed in place, the arc-shaped grooves (6) of the two additional devices of the special lock for the anchor cable are symmetrically buckled into the anchor cable (1), a bolt (8) is inserted into a screw hole (7) and is screwed, and then the existing lock (3) is installed.
When the tool is disassembled, the bolt (8) is disassembled, the special tool to lock additional device for the anchor cable is taken down, and the existing tool to lock 3 loses pressure and can be easily disassembled.
The special tool to lock additional device of anchor rope structural design be reasonable, the preparation is simple and convenient, the practicality is strong, it is convenient to dismantle, and intensity and current anchor rope are different from each other, under the nervous condition of taking over in the pit digging for the anchor rope tool to lock dismantles and becomes high-efficient swift, labour saving and time saving is worth promoting and using in colliery machinery field.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
