[0028] An embodiment of the present application discloses a bridge inspection vehicle driving device with a pneumatic device.

[0029] Reference Figure 1 and Figure 2 A driving device for a bridge inspection vehicle with a pneumatic device comprises a base plate 1, a driving gear 2 is mounted on the base plate 1, and the upper end surface of the base plate 1 is connected to a rectangular box body 3 through a fixing plate, and a driving mechanism 4 for driving the driving gear 2 to rotate and a pneumatic mechanism 5 for controlling the lifting of the driving gear 2 are arranged in the rectangular box body 3; a driven gear 6 is meshingly connected to the outer surface of the driving gear 2, a flange 7 is mounted on the upper end surface of the driven gear 6, a coupling 8 is fixedly mounted on the top surface of the flange 7, a hydraulic rod 9 is mounted on the top of the coupling 8, and a transmission shaft 10 is arranged on the top of the hydraulic rod 9. The driving gear 2 mounted on the base plate 1 rotates under the drive of the driving mechanism 4, and its lifting and lowering are controlled by the pneumatic device, so as to facilitate the clutch of the driving gear 2 and the driven gear 6.

[0030] Reference Figure 1 and Figure 2 The driving mechanism 4 includes a driving gear 41 for driving the driving gear 2 to rotate, which is provided in a rectangular box body 3. The driving gear 41 is driven by a motor 42 on the top of the rectangular box body 3. A rotating shaft 43 is installed on the bottom end surface of the driving gear 41, and the driving gear 2 is fixedly installed on the bottom of the rotating shaft 43. The motor 42 drives the gear at its output end, and the gear meshes with the driving gear 41 for transmission, thereby driving the rotating shaft 43 on the bottom end surface of the driving gear 41 to rotate, thereby driving the driving gear 2.

[0031] Reference Figure 1 and Figure 2 The pneumatic mechanism 5 includes a pneumatic telescopic rod 53 disposed between an upper partition 51 and a lower partition 52 of the rectangular box body 3, wherein the pneumatic telescopic rod 53 is connected to a pipeline of an air pump 54 on the upper partition 51. Under the action of the air pump 54, the pneumatic mechanism 5 drives the pneumatic telescopic rod 53 between the upper partition 51 and the lower partition 52 to rise and fall, thereby adjusting the height of the driving gear 2.

[0032] Reference Figure 1 and Figure 2 The lower partition plate 52 has a through hole 521 at the center for the shaft 43 to pass through, and a wear-resistant layer 522 is arranged around the through hole 521. The through hole 521 at the center of the lower partition plate 52 is used for the shaft 43 to pass through, and the wear-resistant layer 522 around can reduce the wear of the shaft 43 on the lower partition plate 52 after long-term use.

[0033] Reference Figure 1 and Figure 2The surface of the bottom plate 1 is also provided with a limiting groove 11 for the driving gear 2 to be lifted and rotated. A limiting rod 21 is fixed at the bottom of the driving gear 2, and the limiting rod 21 is rotatably connected in the limiting groove 11. A slot 111 is rotatably installed in the limiting groove 11, and the slot 111 is adapted to the limiting rod 21, wherein a longitudinal strip groove body 112 is provided on the side wall of the slot 111 to be adapted to the limiting protrusion 211 on the side of the limiting rod 21. The limiting rod 21 at the bottom of the driving gear 2 can rotate in the limiting groove 11, wherein the limiting rod 21 cooperates with the longitudinal strip groove body 112 on the inner side of the slot 111 through the limiting protrusion 211 on the side, so that the limiting rod 21 can be lifted and lowered in the slot 111. At the same time, the slot 111 rotates in the limiting groove 11, so that the slot 111 can be driven to rotate in the limiting groove 11 during the rotation of the driving gear 2, and the structure can meet the requirements of lifting and rotating at the same time.

[0034] Reference Figure 1 and Figure 2 The driving gear 2 includes a main gear 22 and a sub-gear 23, wherein the main gear 22 meshes with the driven gear 6, and the outer circumferential array of the sub-gear 23 has a plurality of single gear teeth 231, and the gear teeth 231 on the sub-gear 23 correspond to the gear teeth 231 on the main gear 22. The number of gear teeth 231 on the sub-gear 23 is 10. The main gear 22 in the driving gear 2 can mesh with the driven gear 6 for transmission during normal operation, and a plurality of single gear teeth 231 with a smaller number in the circumferential array on the sub-gear 23 can first contact the driven gear 6 when the driving gear 2 is raised or lowered, driving the driven gear 6 to rotate, and then meshing with the main gear 22 for transmission after the driven gear 6 rotates, playing a transition role, avoiding direct collision between the rotating gear teeth 231 on the main gear 22 and the stationary gear teeth 231 on the driven gear 6 to cause damage, thereby improving the service life of the gears.

[0035] Working principle: When in use, the drive device is installed on the differential housing, and a delay device is added to the controller so that the driving gear 2 and the driven gear 6 can be perfectly combined and can form resonance, which is not easy to damage the gears. The motor 42 drives the shaft 43 to rotate through the driving gear 41, and the shaft 43 drives the meshing driven gear 6 to rotate, so that the transmission shaft 10 can be driven to rotate through the coupling 8 and the hydraulic rod 9. Under the action of the pneumatic mechanism 5, the driving gear 2 and the driven gear 6 in the device are clutched. The drive device is matched with the parking brake as a whole. When the drive device runs at a low speed, the equipment is braked smoothly with very little inertia, so that the technicians on the platform do not feel frustrated. A three-position four-way electromagnetic reversing valve and an electronically controlled time-limiting device are added to the parking brake system. After debugging, the vehicle can move forward, backward, and stop on the ramp, solving the problem of the vehicle slipping on the ramp.
