[0022] 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.

[0023] Please see Figure 1-5 As shown, this utility model is a tracked support roller for engineering machinery, including a mounting rod 1 and a wheel body 2. The inner wall of the wheel body 2 is provided with four positioning holes 3 and three snap-fit ​​holes 4. The inner wall of the wheel body 2 is provided with a quick-release sealing assembly 5. The quick-release sealing assembly 5 includes a sealing disc 51 slidably connected to the inner wall of the wheel body 2 and a cover plate 52 provided on the left end of the wheel body 2. The sealing disc 51 is made of tungsten carbide alloy material, which has high hardness, high wear resistance, excellent mechanical properties and corrosion resistance. In the field of sealing rings, the application of tungsten carbide is becoming more and more widespread. It can effectively resist scratches and wear from external objects and ensure the long-term performance of the sealing disc. In addition, tungsten carbide also has good thermal stability and corrosion resistance, and can maintain a stable working state in harsh environments such as high temperature and high pressure. Four positioning rods 53 are fixedly connected to the right side of the sealing disc 51, and a connecting block 54 is fixedly connected to the left side of the sealing disc 51. Spring rods 55 are fixedly connected to the surface of the connecting block 54, and snap heads 56 are fixedly connected to the ends of the spring rods 55. Pull rods 57 are fixedly connected to the surface of the spring rods 55. A first screw 58 is threaded between the connecting block 54 and the inner wall of the cover plate 52. The inner walls of the connecting block 54 and the cover plate 52 are provided with threaded grooves that are compatible with the first screw 58. Three track holes 59 are provided through the cover plate 52. A rotating bar 510 is fixedly connected to the left end of the first screw 58. By setting up the quick-release sealing assembly 5, the sealing ring can be quickly installed by quick positioning and simple spring snap design, saving the installation time of the sealing ring and allowing for quick disassembly and replacement.

[0024] The inner wall of the wheel body 2 is provided with an adapter groove 6, and the surface of the mounting rod 1 is provided with a quick-installation component 7. By setting the quick-installation component 7, the support wheel can be quickly installed on the mounting rod 1, saving time for replacing the support wheel and speeding up work efficiency.

[0025] The quick-installation assembly 7 includes an adapter plate 71 and an installation wheel 72 fixedly connected to the surface of the installation rod 1. The inner wall of the installation wheel 72 is threaded with four second threaded rods 73. The inner wall of the installation wheel 72 has four threaded grooves that are adapted to the second threaded rods. The right end of each of the four second threaded rods 73 is fixedly connected with a screwing block 74.

[0026] There are three spring rods 55, which are arranged in a ring array on the surface of the connecting block 54.

[0027] All four positioning rods 53 are slidably connected to the adjacent positioning holes 3, the three buckle heads 56 are respectively adapted to the adjacent buckle holes 4, and the three pull rods 57 are respectively slidably connected to the adjacent track holes 59.

[0028] The adapter plate 71 and the adapter groove 6 are compatible with each other, and the four second threaded rods 73 are threadedly connected to the wheel body 2. The inner wall of the wheel body 2 has four threaded grooves that are compatible with the second threaded rods 73.

[0029] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0030] The working principle of this utility model is as follows: First, the adapter plate 71 is inserted into the wheel body 2. Then, four screwing blocks 74 drive four second threaded rods 73 to rotate, thereby threading the mounting wheel 72 and the wheel body 2 together, achieving rapid installation of the mounting rod 1, the wheel body 2, and the quick-installation assembly 7. Next, hold the three pull rods 57 with one hand and press them inward, overcoming the elasticity of the three spring rods 55 to drive the three snap-fit ​​heads 56 to move inward. Then, align the four positioning rods 53 and insert them into the four positioning holes 3 to quickly install the sealing plate 51 into the inner wall of the wheel body 2 for sealing. Then, release the three pull rods 57, causing the three snap-fit ​​heads 56 to spring back to their original position by the elasticity of the three spring rods 55, allowing the three snap-fit ​​heads 56 to insert into the three snap-fit ​​holes 4 to lock the sealing plate 51. Next, align and attach the cover plate 52 to the left end of the wheel body 2, and finally turn the rotating bar 510 so that the first screw 58 fixes the connecting block 54 and the cover plate 52 together (reverse the operation once to quickly remove the sealing disc 51).
