[0022] The utility model provides a protective device for inflating tires of a loader, comprising a support frame 1, a gear 2, a first slide bar 6 and a second slide bar 7. The support frame 1 comprises an annular outer frame 101 and a cross 102 arranged in the outer frame 101; the cross 102 is concentric with the outer frame 101, and the four ends of the cross 102 are welded to the four quadrants inside the outer frame 101. A cross groove 1021 that penetrates each other is provided in the cross 102, and the cross groove 1021 is concentric with the cross 102. The gear 2 is hinged at the center of the cross 102 through a rotating shaft 3, and the gear 2 is located in the cross groove 1021.

[0023] The first rack 4 and the second rack 5 are meshed on both sides of the gear 2; the first rack 4 and the second rack 5 both pass through the cross slot 1021 and are vertically distributed to the position where the cross slot 1021 passes through; the cross slot 1021 limits the first rack 4 and the second rack 5. One end of the first rack 4 and the second rack 5 both pass through the outer frame 101 and extend out of the support frame 1; the first rack 4 and the second rack 5 are clearance-matched with the outer frame 101; the ends of the first rack 4 and the second rack 5 extending out of the support frame 1 are symmetrically distributed on both sides of the support frame 1.

[0024] The first slide bar 6 and the second slide bar 7 are respectively arranged on the side of the first rack 4 and the second rack 5 away from the gear 2; the first slide bar 6 and the second slide bar 7 both pass through the cross groove 1021 and are vertically distributed to the position where the cross groove 1021 is passed; the cross groove 1021 plays a limiting role on the first slide bar 6 and the second slide bar 7.

[0025] The outer frame 101 is processed with a slide groove 1011 that matches the first slide bar 6 and the second slide bar 7 on one side through which the first rack 4 and the second rack 5 pass. One end of the first slide bar 6 and the second slide bar 7 respectively matches the slide groove 1011 and extends out of the support frame 1; the ends of the first slide bar 6 and the second slide bar 7 extending out of the support frame 1 are symmetrically distributed on both sides of the support frame 1.

[0026] The first clamping jaw 8 and the second clamping jaw 9 are symmetrically arranged on both sides of the support frame 1. The first clamping jaw 8 is welded to the end of the second rack 5 and the first slide bar 6 extending out of the support frame 1; the second clamping jaw 9 is welded to the end of the first rack 4 and the second slide bar 7 extending out of the support frame 1.

The support frame 1 is fixed with a protective net 10 on one side of the jaws of the first clamping jaw 8 and the second clamping jaw 9 by screws. The function of the protective net 10 is to block the rim part of the tire 13 when the utility model is installed on the loader tire 13 to prevent the rim from jumping out and injuring people. The end of the rotating shaft 3 away from the protective net 10 is fixed with a crank 11 by bolts. The slide groove 1011 is threaded with a set screw 12 on the side away from the protective net 10.

[0027] The specific usage and function of this embodiment are as follows:

[0028] First, by manually turning the crank 11, the shaft 3 is driven to rotate, and the shaft 3 drives the gear 2 to rotate. The gear 2 drives the first rack 4 and the second rack 5 to move synchronously in the opposite direction through meshing transmission, pushing the first rack 4 and the second rack 5 to move outward on both sides of the support frame 1, and then driving the first clamping jaw 8 and the second clamping jaw 9 to move synchronously outward on both sides of the support frame 1 until the distance between the first clamping jaw 8 and the second clamping jaw 9 is greater than the diameter of the tire 13; wherein, since the first clamping jaw 8 is fixedly connected to the second rack 5 and the first slide bar 6, during the movement of the first clamping jaw 8 and the second rack 5, the first slide bar 6 moves synchronously with the above two by sliding cooperation with the slide groove 1011; similarly, since the second clamping jaw 9 is fixedly connected to the first rack 4 and the second slide bar 7, during the movement of the second clamping jaw 9 and the first rack 4, the second slide bar 7 moves synchronously with the above two by sliding cooperation with the slide groove 1011.

[0029] Afterwards, the staff puts the first clamping jaw 8 and the second clamping jaw 9 on the tire 13, and then cranks the crank 11 in the opposite direction to drive the first clamping jaw 8 and the second clamping jaw 9 to move and contract synchronously in the direction of the support frame 1, thereby reducing the distance between the first clamping jaw 8 and the second clamping jaw 9 until the first clamping jaw 8 and the second clamping jaw 9 are clamped and fixed to the tire 13; finally, the staff manually twists the locking screw 12 to respectively fix the first slide bar 6 and the second slide bar 7, thereby locking the position of the first clamping jaw 8 and the second clamping jaw 9, and the installation of the utility model on the tire 13 is completed at this time; the tire 13 can be inflated subsequently.

[0030] After the tire 13 is inflated, the set screw 12 is manually loosened to release the locking state of the first clamping jaw 8 and the second clamping jaw 9, and the crank 11 is manually turned to adjust the distance between the first clamping jaw 8 and the second clamping jaw 9 to be larger than the diameter of the tire 13, and then the protective device can be removed from the tire 13.

[0031] In summary, the utility model can be universally applied to loader tires of different models, and adopts a direct clamping installation method, which effectively improves the service life and universal flexibility of the protective device compared to the prior art.
