[0024] Example

[0025] In order to solve the problem that during the operation of the existing suspension crane in the dust-free clean room, dust and particles are easily generated at the contact surface between the wheels (including the driving wheels and the driven wheels) and the rails and at the driving wheel transmission connection, which will fall onto the surface of the customer's products, thereby directly affecting the quality of the customer's products; Figures 1-4 As shown, the present application discloses a dust collection system for a trolley running mechanism of a suspension crane, comprising an I-shaped steel rail 10, a trolley driving mechanism 20 and a dust removal mechanism 30;

[0026] The trolley driving mechanism 20 includes a driving wheel group 21, a driven wheel group 22, a bridge wheel group 23, a driving device 24 and two [-shaped end beams 25. The two [-shaped end beams 25 are arranged in parallel on both sides of the width of the I-shaped rail 10. The driving wheel group 21 and the driven wheel group 22 are respectively arranged inside the two sides of the length direction of the I-shaped rail 10 and are respectively fixed to the two [-shaped end beams 25; the driving device 24 is arranged on the outside of one of the [-shaped end beams 25 and is connected to the driving wheel group 21. The bridge wheel group 23 is equipped with a driving device 24 and a driving device 24. The dust removal mechanism 30 is arranged at the bottom of the driving wheel group 21 and connected to the two [-shaped end beams 25. The first dust tray 31 is fixed to the two [-shaped end beams 25 below the bridge wheel group 23, and the second dust tray 32 is fixed to the two [-shaped end beams 25 below the driven wheel group 22. The dust collector 33 is arranged on the outside of one of the [-shaped end beams 25 and is connected to the first dust tray 31 and the second dust tray 32 respectively through a suction hose 34.

[0027] During specific use, when the driving device 24 cooperates with the bridge wheel group 23 to drive the active wheel group 21 to rotate, the active wheel group 21 and the driven wheel group 22 will move on the I-shaped rail 10 with the two [-shaped end beams 25. During this process, the dust or particulate matter generated at the contact surface between the active wheel group 21 and the I-shaped rail 10 and the connection between the active wheel group 21 and the bridge wheel group 23 will fall into the first dust accumulation tray 31, and the dust or particulate matter generated at the contact surface between the driven wheel group 22 and the I-shaped rail 10 will fall into the second dust accumulation tray 32. When the vacuum cleaner 33 is working, the suction hose 34 will absorb all the dust or particulate matter in the first dust accumulation tray 31 and the second dust accumulation tray 32, so that the dust or particulate matter will not fall onto the products produced by the customer, thereby avoiding damage to the customer's product quality.

[0028] In some embodiments, the active wheel group 21 of the present application includes two first wheel bodies 211 arranged on both sides of the width direction of the I-shaped rail 10, and the rims of the two first wheel bodies 211 are provided with a toothed structure 2111. The driven wheel group 22 includes two second wheel bodies 221 arranged on both sides of the width direction of the I-shaped rail 10, and the bridge wheel group 23 includes two bearing seats 231 arranged at the bottom of the two [-shaped end beams 25, a transmission shaft 232 passing through the two bearing seats 231, and a transmission shaft 232 passing through the transmission shaft 232 and respectively connected to the two The tooth structure 2111 of the first wheel body 211 is meshed with two bridge gears 233. During specific implementation, the driving device 24 drives one of the first wheel bodies 211 to rotate through the transmission gear 2411. At the same time, the first wheel body 211 will cooperate with the two bridge gears 233 and the rotating shaft to drive the other first wheel body 211 to rotate, and cooperate with the two second wheel bodies 221 to enable the two [-shaped end beams 25 to move on the I-rail 10. As a preferred embodiment of this embodiment, the bearing seat 231 of the present application is a UCP bearing seat 231.

[0029] In one specific embodiment, the driving device 24 of the present application includes a reduction gear 241, a motor 242 and a brake 243 that are integrally connected. The output shaft of the reduction gear 241 is equipped with a transmission gear 2411 that is meshed with the tooth structure 2111 of one of the first wheel bodies 211. This ensures that the two [-shaped end beams 25 can travel at a low speed on the I-rail 10 and can be braked to stop at any position on the I-rail 10.

[0030] In order to better cooperate with the bearing seat 231 and the bridge gear 233 on the transmission shaft 232, the present application provides a shaft sleeve 234 on the transmission shaft 232 corresponding to the bearing seat 231 and the bridge gear 233.

[0031] In order to prevent the two [-shaped end beams 25 from colliding with the outside world and causing damage, the present application provides polyurethane buffers 40 on both sides of the two [-shaped end beams 25 in the length direction to play a protective role.

[0032] In one specific embodiment, the vacuum cleaner 33 has two vacuum heads 331, and two openings (not marked) are provided on the suction hose 34. The two vacuum heads 331 of the vacuum cleaner 33 are respectively inserted into the two openings. When the vacuum cleaner 33 is working, the two vacuum heads 331 of the vacuum cleaner 33 will suck the dust or particles accumulated in the first dust tray 31 and the second dust tray 32 through the suction hose 34 to achieve a cleaning effect, thereby preventing dust or particles from falling onto the surface of the customer's product and causing adverse effects thereon.
