[0001] The utility model relates to the technical field of rope clamping devices, in particular to a mine hoisting rope clamping device. Background Technique

[0002] The mine hoisting cage needs to use a rope clamping device to fix the steel wire rope for cage hoisting. The stability of the rope clamping device for fixing the steel wire rope is directly related to the safety of the cage hoisting process. For example, in a mine rope clamping device (application number: CN202223517169.3) disclosed in Chinese patent literature, the steel wire rope is fixed through a clamping groove body arranged in the middle of the first clamping block and the second clamping block. The clamping groove body is arranged vertically, and a silica gel shell is arranged in the clamping groove body. Although the silica gel shell protects the steel wire rope, the silica gel itself has elasticity and can also be compressed, resulting in the rope clamping device being unable to stably fix the steel wire rope and affecting the safety of mine cage hoisting.

[0003] Therefore, we propose a mine hoisting rope clamping device Content of the Utility Model

[0004] The purpose of the utility model is to provide a mine hoisting rope clamping device to solve the problems put forward in the above background technique.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1-4 , the present invention provides a technical solution: a mine hoisting rope clamping device, which includes a left fixing plate 1, a right fixing plate 2, a steel wire rope 3, an L-shaped positioning plate 4, a first fixing bolt 9 and a nut 10. A sphere 5 is arranged at the bottom end of the steel wire rope 3. A pressing plate 6 is arranged on the L-shaped positioning plate 4. A first arc groove 7 is arranged on the left side of the right fixing plate 2. A second arc groove 8 is arranged on the right side of the left fixing plate 1. Mounting holes 11 matching with the first fixing bolt 9 are arranged on both the left fixing plate 1 and the right fixing plate 2. A third arc groove 12 is arranged at the bottom of the pressing plate 6. A fourth arc groove 13 is arranged on the L-shaped positioning plate 4. A second through hole 19 is arranged at the right end of the third arc groove 12. A first through hole 14 is arranged on the L-shaped positioning plate 4. A second fixing bolt 15 is arranged in the first through hole 14. An installation opening 16 is arranged at the bottom of the pressing plate 6. An installation groove 17 is arranged at the top of the installation opening 16. A fixing block 18 is arranged in the installation groove 17. When the rope clamping device is in use, after the steel wire rope passes through the second arc groove 8 and the first arc groove 7 arranged on the left fixing plate 1 and the right fixing plate 2, and then passes through the second through hole 19, the third arc groove 12 and the fourth arc groove 13, the second fixing bolt 15 is passed through the first through hole 14 and the installation opening 16 to be connected with the fixing block 18. A threaded hole matching with the second fixing bolt 15 is arranged on the fixing block 18. The second bolt 15 is tightened. The second bolt 15 drives the pressing plate 6 to move downward through the fixing block 18 to press the steel wire rope 3. The first fixing bolt 9 is passed through the mounting holes 11 arranged on the left fixing plate 1 and the right fixing plate 2, and the nut 10 is installed on the first fixing bolt 9. The steel wire rope is pulled upward. After the pressing plate 6 contacts the bottoms of the left fixing plate 1 and the right fixing plate 2, the nut 10 is tightened. The second arc groove 8 and the first arc groove 7 arranged on the left fixing plate 1 and the right fixing plate 2 press and fix the steel wire rope 3 again, so as to fix the steel wire rope more firmly.

[0021] Wherein, the top of the L-shaped positioning plate 4 is lower than the top of the pressing plate 6. If the pulling force on the steel wire rope 3 is too large, the steel wire rope slides in the first arc groove 7 and the second arc groove 8. The pressing plate 6 and the L-shaped positioning plate 4 will block the sphere 5 arranged at the bottom end of the steel wire rope 3. The steel wire rope 3 pulls the pressing plate 6 and the L-shaped positioning plate 4, and the steel wire rope 3 pulls the pressing plate 6 and the L-shaped fixing plate 4, so that the left fixing plate 1 and the right fixing plate 2 form a pressure on the pressing plate 6, thereby enabling the pressing plate 6 to further press the steel wire rope 3, so that the device presses and fixes the steel wire rope, and the steel wire rope will not fall off, ensuring the safety of using the rope clamping device;

[0022] The first fixing bolt 9 passes through the mounting holes 11 provided on the left fixing plate 1 and the right fixing plate 2 and is connected to the nut 10. The first fixing bolt 9 passes through the mounting holes 11 and is connected to the nut 10. By tightening the screw nut 10, the left fixing plate 1 and the right fixing plate 2 press and fix the steel wire rope 3.

[0023] Both the first arc groove 7 and the second arc groove 8 are set in an S shape, increasing the contact area between the first arc groove 7 and the second arc groove 8 and the steel wire rope, and fixing the steel wire rope 3 more firmly.

[0024] The second fixing bolt 15 passes through the first through hole 14 and the mounting port 16 and is connected to the fixing block 18. The fixing block 18 is provided with a threaded hole that mates with the second fixing bolt 15. The cross sections of the mounting groove 17 and the fixing block 18 are both square. The height of the mounting groove 17 is greater than the thickness of the fixing block 18. When the steel wire rope 3 pulls the pressing plate 6 and the L-shaped fixing plate 4, causing the left fixing plate 1 and the right fixing plate 2 to exert pressure on the pressing plate 6, and thus when the pressing plate 6 further presses the steel wire rope 3, the fixing block 18 moves within the mounting groove 17, without affecting the further pressing and fixing of the steel wire rope 3 by the pressing plate 6.

[0025] Working principle: After the steel wire rope passes through the second arc groove 8 and the first arc groove 7 provided on the left fixing plate 1 and the right fixing plate 2, it then passes through the second through hole 19, the third arc groove 12, and the fourth arc groove 13. The second fixing bolt 15 passes through the first through hole 14 and the mounting port 16 and is connected to the fixing block 18. The fixing block 18 is provided with a threaded hole that mates with the second fixing bolt 15. By tightening the second bolt 15, the second bolt 15 drives the pressing plate 6 to move downward through the fixing block 18, pressing the steel wire rope 3. The first fixing bolt 9 passes through the mounting holes 11 provided on the left fixing plate 1 and the right fixing plate 2, and the nut 10 is installed on the first fixing bolt 9. By pulling the steel wire rope upward, after the pressing plate 6 contacts the bottoms of the left fixing plate 1 and the right fixing plate 2, the nut 10 is tightened. The second arc groove 8 and the first arc groove 7 provided on the left fixing plate 1 and the right fixing plate 2 perform secondary pressing and fixing on the steel wire rope 3, thereby fixing the steel wire rope more firmly.

[0026] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
