Description

Technical Field

[0001] This utility model relates to the field of mechanical maintenance and installation technology, specifically a tool for removing the pin shaft of a tipper beam. Background Technology

[0002] The tippler's pressing beam is used to press the train car tightly during tippler operation to prevent the train from derailing during the tippler's tipping process. The tippler pressing beam device consists of a pressing beam steel structure, pressing beam hydraulic cylinder, pin shaft, etc. When the pressing beam device malfunctions and needs to be replaced, the most difficult part to remove is the pin shaft. Due to internal corrosion of the pin shaft, a very large axial force is required to separate the pin shaft from the pin shaft hole and the spherical bearing.

[0003] Chinese Patent Publication No. CN201325032Y discloses a tapered pin removal tool, also known as a special pin extractor, used in the installation and maintenance of mechanical equipment. This pin extractor mainly consists of a handle with an internal thread at one end, a lead screw with threads at both ends, and a striking device that fits onto the handle. Practice has proven that this utility model device has a simple structure, is easy to install, is safe and reliable, and highly practical. It can significantly shorten the time required for equipment maintenance and improve work efficiency.

[0004] The above-mentioned device uses a hammer to knock off the pin, but the axial force generated is very small. If gas cutting is used to cut it, the cutting needs to be done while preserving the main steel structure of the tipper beam, which results in a long dismantling time and seriously affects maintenance efficiency. Therefore, this utility model provides a tooling for dismantling the tipper beam pin of a tipper. Utility Model Content

The main structure 1 is fixed to the main structure of the press beam by bolts through the threaded hole 11 on the side of the main structure 1.

[0028] Working principle: During on-site use, the main structure 1 is first placed outside the main structure of the pressure beam to be removed by a hoisting device. The main structure 1 is adjusted until the guide hole 41 in the middle of the reinforcing plate 4 is concentric with the pin shaft of the pressure beam. Bolts are then passed through the threaded holes 11 on the side of the main structure 1 to fix the main structure 1 to the main structure of the pressure beam.

[0029] After fixing the main structure 1, the pressure cap 3 is placed into the groove at the top of the main structure 1, so that the limiting plate 31 is placed between the two mounting holes 2. Then, the mounting pin 5 is inserted into the interior of the mounting hole 2, and the main structure 1 and the pressure cap 3 are assembled by the mounting pin 5. One end of the mounting pin 5 presses the inclined surface of the movable insert 9 to push the movable insert 9 to slide. Then, when the slot 51 is aligned with one end of the movable insert 9, the spring 92 quickly pushes the movable insert 9 into the interior of the slot 51 to install the mounting pin 5 inside the mounting hole 2.

[0030] Then, use a hand chain hoist to place the jack 7 on the placement plate 6, adjust the center of the jack 7 rod to be roughly concentric with the guide hole 41, and start the jack 7 to push out the pin.
