Description

Technical Field

[0001] This utility model relates to the field of mine car bumper processing technology, specifically a special hoisting tool. Background Technology

[0002] Mine car bumpers are devices used in mining operations to prevent collisions between mine cars, primarily installed at both ends of the car frame. During transportation, collisions may occur due to uneven tracks, improper operation, or other reasons. Through their unique structural design, mine car bumpers absorb and disperse collision energy, thereby reducing the damage rate of mine cars and their components, and improving the safety of the entire transportation system.

[0003] During the milling process of mine car bumpers, frequent lifting and rotation are required. However, the bumpers themselves have irregular shapes and uneven weight distribution. Using conventional lifting chains and slings cannot keep them stable, posing a risk of them falling and injuring workers and damaging equipment. Utility Model Content

The metal frame and the connecting shell are connected at the top of the square hoisting metal block, thereby facilitating the disassembly and replacement of the connecting shell and the metal frame.

[0009] Preferably, the high-strength threaded rod is inserted into the middle position of the connecting shell and the top of the rubber block. The high-strength threaded rod locks and fixes the connecting shell and the rubber block, thereby determining the position of the rubber block and facilitating the disassembly and replacement of the rubber block.

[0010] Preferably, the high-strength threaded rods are divided into two groups, which are distributed vertically. One group has two high-strength threaded rods, and the other group has three high-strength threaded rods. The three high-strength threaded rods in the same group are distributed at the top of the rubber block. The high-strength threaded rods lock and fix the metal frame, connecting shell, anti-slip strip and square lifting metal block, thereby determining the position of the rubber block.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-5 The present invention provides the following technical solution:

[0027] A special lifting tool includes a lifting device 1 and a connecting seat 2. A lifting ring 3 is welded to the top surface of the connecting seat 2, and the connecting seat 2 is welded to the top surface of the lifting device 1.

[0028] The hoisting device 1 includes a square hoisting metal block 11. A plug groove 12 is provided on the left side surface of the top of the square hoisting metal block 11. A connecting component 13 is threadedly connected to the top of the square hoisting metal block 11. A threaded hole 14 is provided on the top of the square hoisting metal block 11.

[0029] The connecting component 13 includes a metal frame 131. A rectangular plate 135 is welded to the left side surface of the metal frame 131. A limiting block 134 is welded to the middle position of the right side surface of the rectangular plate 135. The rectangular plate 135 is inserted into the top left side surface of the square hoisting metal block 11. The limiting block 134 is inserted into the top of the square hoisting metal block 11. The limiting block 134 is movably connected to the inner wall surface of the insertion groove 12. The metal frame 131 drives the rectangular plate 135 to move to the right, so that the rectangular plate 135 pushes the limiting block 134 to move to the right, so that the limiting block 134 is inserted into the top of the square hoisting metal block 11, thereby limiting the position of the metal frame 131.

[0030] A high-strength threaded rod 132 is inserted inside the metal frame 131. The high-strength threaded rod 132 is inserted into the inward end of the limiting block 134. The high-strength threaded rod 132 locks and fixes the limiting block 134 and the square hoisting metal block 11, thereby determining the position of the metal frame 131.

[0031] A connecting housing 133 is connected to the surface of a high-strength threaded rod 132. A metal frame 131 is movably connected to the front and rear surfaces of the connecting housing 133. The high-strength threaded rod 132 locks and fixes the metal frame 131 and the connecting housing 133, thereby determining the position of the connecting housing 133 and facilitating its disassembly and replacement. The connecting housing 133 is movably connected to the inner top surface of the square lifting metal block 11. The metal frame 131 is threaded to the top of the square lifting metal block 11. The metal frame 131 and the connecting housing 133 are connected at the top of the square lifting metal block 11, thereby facilitating the disassembly and replacement of the connecting housing 133 and the metal frame 131.

[0032] A rubber block 137 is connected inside the connecting housing 133. A high-strength threaded rod 132 is inserted into the middle position of the connecting housing 133 and the top of the rubber block 137. The high-strength threaded rod 132 locks and fixes the connecting housing 133 and the rubber block 137, thereby determining the position of the rubber block 137 and facilitating the disassembly and replacement of the rubber block 137.

[0033] Anti-slip strips 136 are fixedly connected to the bottom surface of the rubber block 137. High-strength threaded rods 132 are divided into two groups, which are distributed vertically. One group has two high-strength threaded rods 132, and the other group has three high-strength threaded rods 132. The three high-strength threaded rods 132 in the same group are distributed at the top of the rubber block 137. The high-strength threaded rods 132 lock and fix the metal frame 131, the connecting shell 133, the anti-slip strips 136, and the square lifting metal block 11, thereby determining the position of the rubber block 137.

[0034] When in use, push the square lifting metal block 11 to the left end so that the square lifting metal block 11 is inserted into the top of the mine car bumper, and the top surface of the mine car bumper is connected to the rubber block 137 inside the connecting shell 133.

[0035] The anti-slip strip 136 on the bottom surface of the rubber block 137 is connected to the top surface of the mine car bumper to increase the friction between the mine car bumper and the square hoisting metal block 11 and prevent the mine car bumper from detaching from the square hoisting metal block 11.

[0036] At this time, the lifting ring 3 drives the square lifting metal block 11 to one end through the connecting seat 2, so that the square lifting metal block 11 can drive the mine car bumper for transportation, which facilitates the processing of the mine car bumper.

[0037] When encountering mine cars of different specifications, rotate the nut. The nut rotates on the surface of the high-strength threaded rod 132, loosening the connection between the high-strength threaded rod 132 and the square lifting metal block 11. Then, pull the high-strength threaded rod 132 forward.

[0038] The high-strength threaded rod 132 detaches from the square lifting metal block 11, the connecting shell 133 and the metal frame 131. At this time, the connecting shell 133 drives the anti-slip strip 136 and the rubber block 137 to move downward, allowing the connecting shell 133 to detach from the square lifting metal block 11.

[0039] Pull the rubber block 137 downwards to detach it from the connecting housing 133, making it easier to replace the rubber block 137.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
