[0023] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.
[0024] Due to the unique structure and harsh working environment of the vertical shaft, it is difficult to apply force during disassembly, requiring considerable force to remove it, making disassembly quite challenging. Traditional disassembly methods often lack specialized tools, simply involving screwing a screw into the threaded hole of the vertical shaft, tying a wire to the bolt, and pulling. Uneven force on the wire can easily cause it to break, and the disassembly process can also damage the threaded hole of the vertical shaft. Therefore, it is inefficient, and if the wire breaks, the vertical shaft will fall and collide with surrounding components, easily causing damage to the vertical shaft and surrounding parts.
[0025] The present invention will now be described in detail with reference to the accompanying drawings. This embodiment discloses a tool for disassembling the vertical shaft of a mining dump truck, such as... Figure 1 As shown, the disassembly tool includes a disassembly tool body 1, a disassembly component 2, a lifting device mounting hole 3, and a connecting hole 4. The disassembly component 2 is located at the center of the upper end of the disassembly tool body 1. The lifting device mounting hole 3 is located on the disassembly component 2. Several connecting holes 4 are arranged at intervals around the disassembly component 2. The connecting holes 4 are located on the disassembly tool body 1, and the location of the connecting holes 4 is aligned with the location of the threaded holes on the vertical shaft.
[0026] A connecting hole 4 is provided on the main body 1 of the disassembly tool. When it is necessary to disassemble the vertical shaft, align the connecting hole 4 with the threaded hole on the vertical shaft, and screw the bolts into the connecting hole 4 and the threaded hole in sequence. Hang the lifting device on the lifting device mounting hole 3 on the disassembly part 2, and start the lifting equipment to lift the vertical shaft. The overall structure is simple and ingeniously designed, which greatly improves the disassembly efficiency of the vertical shaft of the mining dump truck. It has significant practical value and economic benefits, reduces maintenance costs and time loss, realizes the disassembly of the vertical shaft, and has high disassembly efficiency, thereby improving the efficiency of vertical shaft replacement and maintenance.
[0027] The disassembly tool body 1 has a disc-like structure, and its diameter is the same as that of the vertical shaft. Setting the diameter of the disassembly tool body 1 to be the same as that of the vertical shaft makes it easier to ensure the accurate installation position of the disassembly tool during installation, and thus facilitates the alignment of the connecting hole 4 and the threaded hole.
[0028] The dismounting tool body 1 is fixedly connected with the dismounting part 2, and the dismounting part 2 is a semicircular structure. The lifting tool mounting hole 3 penetrates the dismounting part 2, and the lifting tool mounting hole 3 is a semicircular hole. The center position of the dismounting part 2 coincides with the center position of the dismounting tool body 1. The lifting tool mounting hole 3 is used for mounting a lifting tool, and after the lifting tool is mounted, hoisting is carried out, and the dismounting part 2 is located at the center position of the dismounting tool body 1, so that the stability during hoisting is ensured, collision between the vertical shaft and surrounding parts is avoided, and then the vertical shaft and the surrounding parts are prevented from being damaged during dismounting.
[0029] The connecting hole 4 penetrates the dismounting tool body 1, and the connecting hole 4 is a circular hole. A bolt is arranged in the connecting hole 4, and the bolt is used for connecting the dismounting tool body 1 and the vertical shaft. The diameters of the plurality of connecting holes 4 are the same. The dismounting tool body 1 and the vertical shaft are detachably connected.
[0030] The dismounting tool body 1 is uniformly provided with 12 connecting holes 4 above, which are connected with 12 screw holes in the upper part of the vertical shaft by bolts; a large semicircular structure is arranged above, the center of which coincides with the body, and a plurality of lifting tool mounting holes 3 are arranged at the edge of the large semicircular structure and are used for mounting a lifting tool. This design is accurate for the structure of the vertical shaft, the connection is stable, hoisting operation is facilitated, dismounting convenience and safety are improved, and the risk of damage to parts is effectively reduced.
[0031] The number and distribution form of the connecting hole 4 can be considered to be changed, such as adopting a ring array or non-uniform distribution, adapting to different screw hole layouts of the vertical shaft; or the size and radian of the semicircular structure are adjusted to match various specifications of the vertical shaft; the position and diameter of the lifting tool mounting hole 3 can also be changed to be compatible with various lifting tools.
[0032] Although the specific embodiments of the utility model have been described in combination with the drawings, it is not a limitation on the protection scope of the utility model, and those skilled in the art should understand that various modifications or changes made by those skilled in the art on the basis of the technical scheme of the utility model without creative labor are still within the protection scope of the utility model.
