To improve crane efficiency and safety, designing crane wheels that facilitate loading and unloading is particularly important.

[0003] Patent specification with publication number CN 203497938 U discloses a crane wheel assembly that is easy to load and unload. The assembly includes a wheel axle, a wheel mounted on the wheel axle, a self-aligning bearing, and a shaft sleeve. The self-aligning bearing is built into the wheel and is a stepped shaft. The utility model has a simple structure, is easy to disassemble, and is easy to adjust.

[0004] However, in the implementation of related technologies, it was found that the above-mentioned crane wheel assembly that is easy to load and unload has the following problems: the device is complicated to disassemble and operate during use, which makes it inconvenient to repair and replace the wheel assembly. At the same time, the bearings and sleeves are prone to wear and displacement during use. Therefore, we propose a crane wheel assembly that is easy to load and unload. Utility Model Content

Both ends of the first mounting block 8 and the second mounting block 9 are provided with a second threaded hole 15. The first mounting block 8 and the second mounting block 9 are fixedly installed by a second bolt 16. The outer wall of the second bolt 16 is installed with a spring 17. The outer wall of the first bearing 1 is symmetrically provided with a slide groove 18. The first bearing 1 is movably mounted with a bearing cover 12 through the slide groove 18, and the inner wall of the bearing cover 12 is symmetrically provided with a slider 13.

[0027] In this embodiment, the inner walls of the first mounting block 8 and the second mounting block 9 are provided with positioning grooves 10 , and the positioning grooves 10 and the second bearing 2 fit together.

[0028] In this embodiment, an inner wall of the second threaded hole 15 is provided with an internal thread, and the internal thread matches the external thread provided on the outer wall of the second bolt 16 .

[0029] In this embodiment, the sliding groove 18 is an arc-shaped groove, and the slider 13 and the sliding groove 18 fit together.

[0030] In this embodiment, the outer diameter of the third bearing 3 is greater than the outer diameter of the second bearing 2 , and the outer diameter of the second bearing 2 is greater than the outer diameter of the first bearing 1 .

[0031] Specific examples Figure 1 、 Figure 3 and Figure 4 As shown, when using this structure, when it is necessary to dismantle and repair the wheel group main body 4, the second bolt 16 is rotated, and the spring 17 provided on the outer wall of the second bolt 16 can prevent the second bolt 16 from being stripped. At the same time, the first bolt 14 is rotated to disengage the side surfaces of the first mounting block 8 and the second mounting block 9 from the outer wall of the bearing cover 12, separate the first mounting block 8 and the second mounting block 9, and peel off the first mounting block 8 and the second mounting block 9 from the outer wall of the second bearing 2. The bearing cover 12 is pulled out from one side of the first bearing 1 by using the slider 13 and the slide groove 18. At the same time, the mounting seat 6 is pulled out from the outer wall of the second bearing 2 by using the movable groove 7 provided on the inner wall of the mounting seat 6. The wheel group main body 4 is limited by the limiting groove 5 and the limiting block 20, and the wheel group main body 4 is slid from the outer wall of the third bearing 3 and removed from one end of the first bearing 1. This device facilitates the disassembly and maintenance of the wheel group main body 4.

[0032] Example 2: The side walls of the first mounting block 8 and the second mounting block 9 are evenly provided with first threaded holes 11 , and the first mounting block 8 and the second mounting block 9 are fixedly connected to the side walls of the second bearing 2 by first bolts 14 .

[0033] In this embodiment, the cross section of the limiting block 20 is rectangular, and the limiting block 20 and the limiting groove 5 fit together.

[0035] Specific examples Figure 1 、 Figure 2 and Figure 5 As shown, when this structure is used, the wheel group body 4 can be slid and adjusted in position on the outer wall of the third bearing 3 by utilizing the limiting grooves 5 set on both sides of the wheel group body 4 and the limiting blocks 20 set on the outer wall of the third bearing 3. At the same time, the mounting seat 6 is used to clamp the two sides of the wheel group body 4 to limit and fix the limiting grooves 5. Adjusting the wheel group body 4 to a suitable position can effectively reduce the wear of the wheel group body 4, reduce the running resistance and avoid the wheel group body 4 from being installed loosely and causing noise during operation.

[0036] Working principle: When the wheel group body 4 is in use, the limiting grooves 5 set on both sides of the wheel group body 4 and the limiting blocks 20 set on the outer wall of the third bearing 3 can be used to slide the wheel group body 4 on the outer wall of the third bearing 3 to adjust the position. At the same time, the mounting seat 6 is used to clamp the two sides of the wheel group body 4 to limit and fix the limiting grooves 5. Adjusting the wheel group body 4 to a suitable position can effectively reduce the wear of the wheel group body 4, reduce the running resistance and the noise generated by the operation. When the wheel group body 4 needs to be disassembled and repaired, the second bolt 16 is rotated. The spring 17 set on the outer wall of the second bolt 16 can prevent the second bolt 16 from being dethreaded. At the same time, the first bolt 14 is rotated to make the side surfaces of the first mounting block 8 and the second mounting block 9 aligned with the bearing cover 12. The outer wall is disengaged, the first mounting block 8 and the second mounting block 9 are separated, the first mounting block 8 and the second mounting block 9 are peeled off from the outer wall of the second bearing 2, and the bearing cover 12 is pulled out from one side of the first bearing 1 using the slider 13 and the slide groove 18. At the same time, the mounting seat 6 is pulled out from the outer wall of the second bearing 2 using the movable groove 7 set on the inner wall of the mounting seat 6. The wheel group body 4 is limited by the limiting groove 5 and the limiting block 20, and the wheel group body 4 is slid from the outer wall of the third bearing 3 and removed from one end of the first bearing 1. This device facilitates the disassembly and maintenance of the wheel group body 4, and can adjust the position of the wheel group body 4 on the third bearing 3 and provide it with stable clamping and fixation, which can effectively avoid the gap between the third bearing 3 and the wheel group body 4 and wear, thereby reducing noise.
