Detailed Description

The technical scheme of the invention is further explained in detail by combining the attached drawings:

the invention provides an automatic inspection driving system with a traveling wheel with a rim tread and wheel teeth, which comprises a guide rail and an inspection device 1, wherein the guide rail comprises a horizontal guide rail 14 and a slope guide rail 11, the inspection device 1 is provided with a driving device, the driving device comprises a motor 3, a motor shaft of the motor 3 is connected with a traveling wheel 9, one part of the traveling wheel 9 along the axial direction is a gear 9-3, the other part of the traveling wheel 9 is a flat pulley hub with a rim tread 9-2, the flat pulley hub is externally sleeved with a rubber sleeve 9-1, and the outer diameter of the rubber sleeve 9-1 is not less than the outer diameter of the gear 9-3; and a rack 12 meshed with the gear 9-3 is arranged on the slope guide rail 11, and a guide wheel 15 in sliding connection with the bottom of the guide rail is arranged right below the guide rail on the inspection device 1.

The bottom of the guide rail is provided with a guide groove, and the guide wheel 15 is connected with the guide groove in a rolling manner. The wheel surface of the guide wheel 15 is in rolling connection with the side wall of the guide groove, an outer edge is arranged on one side, away from the guide rail, of the guide wheel 15 and is in contact with the end face of the guide groove, and the width of the guide wheel 15 is smaller than the groove depth of the guide groove. The guide rail is provided with a baffle plate at one side close to the motor 3, and the end face of the rubber sleeve 9-1 is abutted against the baffle plate.

Specifically, as shown in fig. 1 and 2, the inspection device 1 is fixed on the lower side of the support base plate 2, the motor support 4, the bearing seat 7 and the guide wheel 15 are installed on the upper side of the support base plate 2, and the motor 3 is fixed on the motor support 4; the bearing seat 7 prevents the motor 3 from bearing the overturning moment and has the function of fixing the supporting shaft 8; one end of the supporting shaft 8 is connected with an output shaft of the motor 3 through a coupler 5, and the other end of the supporting shaft is provided with a travelling wheel 9; the rear side of the travelling wheel 9 is positioned by adopting a shaft shoulder, and the front side of the travelling wheel is positioned by adopting a round nut 10; the side surfaces of the horizontal guide rail 14 and the slope guide rail 11 are connected with a plurality of upright posts 13; in the transition region of the up-slope and the down-slope, the tail part of the horizontal guide rail 14 is connected with the head part of the slope guide rail 11 at equal height.

As shown in figure 3, one half of the circumference of the road wheel 9 is a gear 9-3 with evenly distributed gear teeth, the other half of the circumference is a flat pulley hub with a rim tread 9-2, and a layer of rubber sleeve 9-1 is sleeved outside the flat pulley hub.

As shown in fig. 1 and 5, the inspection apparatus 1 moves horizontally along the horizontal guide rail 14. The output shaft of the motor 3 rotates to drive the shaft coupling 5 to rotate, then drives the supporting shaft 8 to rotate, so that the travelling wheels 9 on the supporting shaft 8 roll on the horizontal guide rail 14, and the inspection device 1 horizontally moves along the horizontal guide rail 14. The rear side of the road wheels 9 abuts against a baffle plate at the top of the horizontal guide rail 14. When the travelling wheels 9 roll on the horizontal guide rails 14, in order to avoid abrasion caused by contact between the gears 9-3 and the horizontal guide rails 14, the outer diameter of the rubber sleeve 9-1 is still larger than the diameter of the addendum circle of the gears 9-3 after the rubber sleeve 9-1 generates maximum deformation under the maximum load operation. The guide wheel 15 is in rolling connection with a guide groove at the bottom of the guide rail and is used for assisting the movement of the inspection device 1; the outer edge of the guide wheel is tightly attached to the end face of the guide groove at the bottom of the guide rail, so that the limiting effect is achieved, and the inspection device 1 can be prevented from swinging. The guide wheel 15 ensures that the inspection device 1 only moves along the guide rail and has the function of balancing moment.

As shown in fig. 1 and 5, when moving up and down a slope, the gear 9-3 is engaged with the rack 12, and the output shaft of the motor 3 rotates to drive the gear 9-3 to rotate, so that the inspection device 1 moves along the slope guide rail 11. The rear side of the walking wheel 9 is tightly attached to a baffle plate at the top of the slope guide rail 11, and the rack 12 is installed on the slope guide rail 11. The guide wheels 15 ensure that the inspection device 1 only moves along the slope guide rail 11 and have the function of balancing moment.

Description of the drive method: as shown in FIG. 1, when the inspection device works, if the inspection device 1 moves horizontally, the friction type transmission of the walking wheels 9 and the horizontal guide rails 14 is adopted; if the inspection device 1 moves up and down the slope, the gear 9-3 and the rack 12 are engaged for transmission; when the inspection device 1 is to convert horizontal movement into up-and-down-slope movement, if the gear 9-3 and the rack 12 are not exactly meshed, self-regulation is performed by slipping the travelling wheels 9 on the horizontal guide rail 14, so that the gear 9-3 is meshed with the rack 12, and then the inspection device 1 moves along the slope guide rail 11.
