DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0024] Please refer to Figure 1 、Figure 3 , Figure 4 and Figure 5 , this embodiment provides an explosion-proof crane wheel set, including a track 1. A movable connection is provided at the top of the track 1 with an explosion-proof wheel body 2 for rolling along the track 1. Fixed rings 21 for fixation are fixedly installed on both sides of the explosion-proof wheel body 2. A first limit seat 3 and a second limit seat 31 for limiting the explosion-proof wheel body 2 are respectively sleeved on both sides of the track 1. The inner walls of the tops of the first limit seat 3 and the second limit seat 31 are respectively rotatably connected to the outer sides of the fixed ring 21. A plurality of first flow guide components 4 for air transition are provided on the inner side wall of the explosion-proof wheel body 2. Second flow guide components 5 for air transition are provided on the inner side walls of both sides of the first limit seat 3. A plurality of first flow guide rods 22 for guiding the air inside the first flow guide component 4 are rotatably connected to the inner side wall of the explosion-proof wheel body 2. Second flow guide rods 32 for guiding the air inside the second flow guide component 5 are rotatably connected to the inner side walls of both sides of the first limit seat 3. A driving component 6 for driving the rotation of the first flow guide rod 22 and the second flow guide rod 32 is provided on the inner side wall of the first limit seat 3. While the explosion-proof wheel body 2 rolls on the track 1, the movement of the explosion-proof wheel body 2 causes the first limit seat 3 and the second limit seat 31 to slide along both sides of the track 1, playing a role in limiting the explosion-proof wheel body 2. While the explosion-proof wheel body 2 is rolling, through the action of the driving component 6, the first flow guide rod 22 on the explosion-proof wheel body 2 can rotate, thereby playing a positive or reverse flow guiding role for the air inside the first flow guide component 4. Thus, through the first flow guide component 4 and the first flow guide rod 22, the dust or impurities on the track 1 below the explosion-proof wheel body 2 are discharged outwards. When the explosion-proof wheel body 2 rotates in the reverse direction, the dust on the track 1 can be similarly extracted into the interior by the first flow guide component 4 and the first flow guide rod 22 and then discharged outwards. At the same time, the second flow guide rod 32 inside the first limit seat 3 can rotate synchronously on the first limit seat 3. Through the rotation of the second flow guide rod 32 and the action of the second flow guide component 5, the air flow inside the second flow guide component 5 can blow away the dust and impurities on the inner side track 1 of the first limit seat 3, or when the explosion-proof wheel body 2 rotates in the reverse direction, extract the dust and impurities into the second flow guide component 5 and then discharge them outwards, thereby preventing the damage caused by the residue of dust and debris on the track 1 to the rolling of the explosion-proof wheel body 2;

[0025] Please refer to Figure 2 , Figure 3 , Figure 4 and Figure 5, in this embodiment, an explosion-proof crane wheel set is proposed. The drive assembly 6 includes drive rods 61 rotatably connected to the inner side walls of both sides of the first limit seat 3. Drive gears 62 are fixedly installed at one end of each drive rod 61 and the other end of the first diversion rod 22. The drive assembly 6 further includes outer tooth rings 63 fixedly installed on both sides of the explosion-proof wheel body 2. An inner tooth ring 64 is fixedly installed on the inner side wall of one of the first limit seats 3. Both the outer tooth ring 63 and the inner tooth ring 64 are engaged with the drive gears 62. The drive assembly 6 further includes pulleys 65 fixedly installed at the other ends of the drive rod 61 and the second diversion rod 32. A transmission belt 66 is sleeved on the outside of the pulley 65. When the explosion-proof wheel body 2 rotates relative to the first limit seat 3, the explosion-proof wheel body 2 can drive the outer tooth ring 63 to rotate on the inner wall of the first limit seat 3, so that the drive gear 62 on the drive rod 61 can rotate due to the rotation of the outer tooth ring 63, and then drive the second diversion rod 32 to rotate through the action of the pulley 65 and the transmission belt 66. The first diversion rod 22 on the explosion-proof wheel body 2 can rotate along with the explosion-proof wheel body 2 on the inner wall of the inner tooth ring 64, so that it can rotate inside the explosion-proof wheel body 2 through the action between the drive gear 62 on the first diversion rod 22 and the inner tooth ring 64. The first diversion assembly 4 includes a plurality of first transition boxes 41 fixedly installed on the inner side wall of the explosion-proof wheel body 2. The inner side walls of the plurality of first transition boxes 41 are rotatably connected to the outside of the first diversion rod 22. The first diversion assembly 4 further includes a plurality of bottom pipes 42 communicated with the bottom ends of the first transition boxes 41. A top pipe 43 is communicated with the top end of the first transition box 41. The outside of the top pipe 43 is fixedly connected to the inner side walls of the explosion-proof wheel body 2 and the fixed ring 21 respectively. The first diversion rod 22 rotates inside the first transition box 41. When the explosion-proof wheel body 2 rotates clockwise, air is diverted into the first transition box 41 through the top pipe 43 and then discharged outward from the bottom pipe 42, so as to blow the impurities on the track 1. When the explosion-proof wheel body 2 rotates counterclockwise, similarly, through the reverse rotation of the first diversion rod 22, the dust and impurities on the track 1 are pumped from the bottom pipe 42 into the first transition box 41 and then discharged outward from the top pipe 43. The second diversion assembly 5 includes second transition boxes 51 fixedly installed on the inner side walls of both sides of the first limit seat 3. The inner side walls of the second transition boxes 51 are rotatably connected to the outside of the second diversion rod 32. The second diversion assembly 5 further includes three inner pipes 52 communicated with one side of the second transition box 51. An outer pipe 53 is communicated with the other side of the second transition box 51. The outside of both the outer pipe 53 and the inner pipes 52 are fixedly connected to the inner side wall of the first limit seat 3. When the explosion-proof wheel body 2 rotates clockwise, through the rotation of the second diversion rod 32 inside the second transition box 51, the second transition box 51 can divert air into the inside through the outer pipe 53 and output it to the surface of the track 1 from the inner pipes 52, so as to remove the dust on the track 1. Similarly, through the reverse rotation of the explosion-proof wheel body 2, the second diversion rod 32 rotates in the reverse direction, and the dust and impurities on the track 1 are pumped into the second transition box 51 through the inner pipes 52 and then discharged outward from the outer pipe 53.

[0026] In this embodiment, during use, through the rolling of the explosion-proof wheel body 2 on the track 1, the first limiting seat 3 and the second limiting seat 31 slide along both sides of the track 1 to limit the explosion-proof wheel body 2. At the same time, through the rotation of the first limiting seat 3 relative to the explosion-proof wheel body 2, the first guide rod 22 on the explosion-proof wheel body 2 can rotate under the action of the driving gear 62 and the internal gear ring 64. Thus, through the rotation of the first guide rod 22 inside the first transition box 41, the dust and impurities on the track 1 below the explosion-proof wheel body 2 are blown away or absorbed into the interior and discharged. The second guide rod 32 can also rotate inside the second transition box 51 under the action of the driving gear 62 on the driving rod 61 and the external gear ring 63, blowing away or absorbing the dust and impurities on the track 1 inside the first limiting seat 3 and discharging them outward. Thereby, the damage caused by the residue of dust and debris on the track 1 during the rolling of the explosion-proof wheel body 2 is prevented.

[0027] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
