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, in embodiment 1 of the present invention, a detachable lock dedicated for an anchor cable includes: arc liner 1, fastening nut 2, tray 3, the horizontal cross-section of arc liner 1 is the arc, and longitudinal section is the arc, and the medial surface of arc liner 1 sets up barb 5, and aim at increases the frictional force with the anchor rope, and the lateral surface of arc liner 1 sets up screw thread 4, uses with fastening nut 2, tray 3's screw-thread fit, and tray 3 shape is roughly hollow dish, and is slightly higher all around, and the center is slightly low, sets up the internal thread that agrees with 1 lateral surface screw thread of arc liner at dished cavity position.

The arc-shaped gasket 1 is used in pairs.

Example 2

Please refer to fig. 2, which is a top view of a detachable lock arc-shaped liner for an anchor cable, wherein a cross section of the arc-shaped liner is arc-shaped, an inner arc is provided with barbs, which can effectively increase a contact area with the surface of the anchor cable and increase friction force, the outer surface of the arc-shaped liner is provided with threads, which are used in cooperation with the threads of a fastening nut 2 and a tray 3, and the arc-shaped liner is longitudinally cut in a direction perpendicular to the inner arc surface, and the longitudinal cutting surface is also arc-shaped, so that when two sides of the arc-shaped liner 1 are in contact with the anchor cable 8, the center of the arc-shaped liner 1 is in closer contact with the anchor cable 8 and has higher pressure, and when the arc-shaped liner 1 is disassembled, due to the structural factor of the arc-shaped liner, a force separating from the anchor cable 8 is generated.

Example 3

Referring to fig. 3, embodiment 3 of the present invention is a top view of a detachable lock tray 3 dedicated for anchor cables, which is slightly higher around and slightly lower at the center, so that when acting force is generated with coal, the surrounding force will gather at the center of the tray 3, and finally the pressure of the tray 3 and the arc-shaped pad 1 on the anchor cable 8 is converted into pressure, thereby effectively preventing the coal from collapsing.

Example 4

Referring to fig. 4, embodiment 4 of the present invention is a schematic diagram of an installation process of a detachable lock dedicated for an anchor cable, wherein during installation, the tray 3 and the nut 2 are closed together, when the tray 3 reaches a specific position, the nut 2 is rotated in a reverse direction, and due to the structural factor of the arc-shaped gasket 1, the pressure of the arc-shaped gasket 1 on the anchor cable 8 increases gradually along with the increase of the distance between the nut 2 and the tray 3 until the nut 2 reaches a proper position.

Example 5

Referring to fig. 5, embodiment 5 of the present invention is a schematic view of a disassembled state of a detachable lock dedicated for anchor cables, wherein during the disassembly, the tray 3 is rotated reversely, the pressure of the tray 3 on the anchor cable 8 is gradually released, and when the position of the nut 2 is rotated, the tray rotates together with the nut 2 until the tray is separated from the arc-shaped liner 1, thereby completing the disassembly.

The embodiment of the utility model provides a theory of operation is:

during the installation, tray 3 and nut 2 are drawn together, and when tray 3 reachd the assigned position, the antiport nut 2, because of arc liner 1 self construction factor, the pressure of arc liner 1 to anchor rope 8 can be along with nut 2 and tray 3's distance increase and increase gradually, until nut 2 reachs suitable position.

When the anchor cable is disassembled, the tray 3 is rotated reversely, the pressure of the tray 3 on the anchor cable 8 is gradually released, and when the position of the nut 2 is rotated, the tray and the nut 2 rotate together until the anchor cable is separated from the arc-shaped gasket 1, and the disassembly is completed.

A special detachable tool to lock of anchor rope structural design is reasonable, the preparation is simple and convenient, the practicality is strong, it is convenient to dismantle, and intensity and current anchor rope are not about same, under the nervous condition of taking over in the pit digging for the anchor rope tool to lock dismantles to become 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.
