Description

Technical Field

[0001] The utility model belongs to the field of high-altitude operation hooks, and specifically relates to a high-altitude operation hook for mine safety engineering. Background Art

[0002] Aerial work hooks, also called safety hooks and master locks, are the most commonly used connection tools for connecting ropes, flat belts, anchor points, equipment, etc. Safety hooks must be equipped with a locking function. The locking function is divided into two categories: manual lock and automatic lock. The manual lock is suitable for use in most environments, but it must be locked immediately after connection, otherwise the lock door may be opened due to accidental equipment collision during operation, resulting in an accident. The unlocked hook is like the state of the gate being opened, and its tension (breaking load) is much lower than the locked state. There are two types: ordinary type (rotating type) and spring hook (self-locking type). The shapes are mostly "D" (rescue, military) and "8" (engineering, construction).

[0003] In existing mining projects, when performing high-altitude operations, most of the hooks are fixed with threaded barrels. Since the hooks are subjected to relatively large forces during high-altitude operations, long-term use of the threaded barrels will cause the thread to slip or become damaged. When performing high-altitude operations, it is necessary to fully ensure the safety of the lifting, otherwise it is easy to cause safety accidents.

[0004] In view of this, the present utility model is proposed. Utility Model Content

DETAILED DESCRIPTION

[0028] The utility model will now be further described in detail with reference to the accompanying drawings.

[0029] See also Figure 1-6As shown, in this embodiment, a high-altitude operation hook for mine safety engineering is provided, including a hook body 1, one end of the hook body 1 is rotatably matched with a rotating rod 2, and the other end of the rotating rod 2 is connected to the hook body 1. A fixing device is installed;

[0030] The fixing device includes a fixing plate 4, which is installed at the connection between the rotating rod 2 and the hook body 1. The other end of the hook body 1 is provided with a fixing groove 6. The bottom of the fixing plate 4 is provided with a trapezoidal block 5. The fixing plate 4 and the trapezoidal block 5 slide inside the fixing groove 6. A cavity is provided inside the trapezoidal block 5. Springs 8 are installed on both sides of the inner wall of the trapezoidal block 5. A moving plate 9 is installed at one end of the spring 8. A clamping plate 11 is installed on one side of the moving plate 9. A moving groove 13 is provided on one side of the trapezoidal block 5. A limiting telescopic rod 10 is installed between the moving plate 9 and the inner wall of the trapezoidal block 5. A moving device is installed on the side of the cavity of the trapezoidal block 5 away from the fixing device. A clamping groove 12 is provided on the side of the two clamping plates 11 away from the spring 8. The connection between the hook body 1 and the rotating rod 2 is an elastic rotation setting.

[0031] The application of one aspect of this embodiment is as follows: when in use, the user places the rope through the rotating rod 2. When the rope is placed, the rotating rod 2 will rebound under the action of elasticity. When the rotating rod 2 moves to the inside of the fixed groove 6, the fixed column 18 will move between the two clamping plates 11 through the movable groove 13. Under the action of the spring 1 8, the clamping plate 11 clamps the fixed column 18 through the clamping groove 12, thereby completing the fixation of the fixed column 18. When the rotating rod 2 rebounds, the fixed column 18 will hit the sliding rod 16, thereby causing the sliding rod 16 to move. When the sliding rod 16 moves to the inside of the sliding groove 15, under the action of the spring 2 17, the sliding plate 14 moves downward on the outer surface of the sliding rod 16. The movement of the sliding plate 14 drives the fixed tube 3 to move. When the fixed tube 3 moves to the bottom, the second fixation of the connection can be completed. The sliding rod 16 and the spring 2 17 are located at the central part of the sliding plate 14, and the spring 2 17 is located on both sides of the central part of the upper surface of the sliding plate 14.

[0032] The moving device of this embodiment includes a sliding rod 16, which is slidably fitted in the interior of the fixed plate 4 through the moving groove 13. A sliding plate 14 is installed on the top of the fixed plate 4. A spring 21 is installed between the sliding plate 14 and the top of the inner wall of the fixed plate 4. A spring 3 21 is installed on one side of the inner wall of the moving groove 13. Through grooves 22 are provided on both sides of the fixed plate 4. The sliding plate 14 slides inside the through groove 22. Both ends of the sliding plate 14 pass through the through groove 22 and extend to the outside of the through groove 22. The outside of the fixed plate 4 is slidably fitted with a fixed cylinder 3. The inner wall surface of the fixed cylinder 3 is fixedly connected to the two ends of the sliding plate 14. A limiting telescopic rod 20 is installed between the sliding rod 16 and one side of the inner wall of the fixed plate 4. When the rotating rod 2 rebounds, the fixed column 18 hits the sliding rod 16, causing the sliding rod 16 to move. When the sliding rod 16 moves to the inside of the sliding groove 15, under the action of the spring 17, the sliding plate 14 moves downward on the outer surface of the sliding rod 16. The movement of the sliding plate 14 drives the fixed tube 3 to move. When the fixed tube 3 moves to the bottom, the second fixation of the connection is completed.

[0033] In this embodiment, a fixing column 18 is installed on one side of the inner wall of the fixing groove 6, and an annular groove 19 is formed on the surface of one end of the fixing column 18, and the annular groove 19 cooperates with the two clamping plates 11. The fixing column 18 moves between the two clamping plates 11 through the moving groove 13, and under the action of the spring 18, the clamping plate 11 clamps the fixing column 18 through the clamping groove 12.

[0034] One side of the trapezoidal block 5 of this embodiment is slidably matched with two moving blocks 7, which are movably extended to the inside of the trapezoidal block 5 and fixedly connected to the moving plate 9. The staff moves the two moving blocks 7 so that the two clamping plates 11 release the fixing of the fixed column 18.

[0035] The present invention is not limited to the above-mentioned implementation modes. Anyone should be aware of the structural changes made under the inspiration of the present invention. Any technical solution that is the same or similar to the present invention falls within the protection scope of the present invention. The technology, shape, and structure that are not described in detail in the present invention are all known technologies.
