Description

Technical Field

[0001] This utility model relates to the technical field of tire explosion-proof devices, specifically a tire inflation explosion-proof device for heavy vehicles. Background Technology

[0002] The tire pressure of heavy vehicles such as dump trucks and cargo trucks in the aluminum company's transportation workshop may drop during operation, requiring frequent tire pressure replenishment to prevent tire damage due to insufficient tire pressure. During the inflation process, due to aging or hard damage to some tires, there is a possibility of tire explosion, which could cause blast injuries to operators.

[0003] Application No. 201920768185.9 discloses a tire inflation protection bracket, including a base plate placed on the ground, a baffle plate provided on the base plate, the baffle plate being perpendicular to the base plate, an even number of fixing posts symmetrically arranged on the baffle plate to cooperate with the tire, and the fixing posts being located on the side of the baffle plate close to the tire, a connecting rod passing through adjacent fixing posts, and a connecting hole provided on the fixing post for the connecting rod to be sleeved and connected, and an inflation hole provided in the center of the baffle plate.

[0004] The proposed solution in application number 201920768185.9 can reduce the damage to people and property caused by tire explosions, but its disadvantages are: 1. Locking and unlocking the tire inflation protection bracket to the wheel hub requires workers to crawl under the vehicle or reach their hands under the vehicle to complete the task. The space under the vehicle is small, making the operation difficult and easily soiling the workers' clothes or bodies; 2. The tire inflation protection bracket only has a baffle at the front to block the impact of the explosion, and there are no protective plates on the sides, so it cannot block the impact of the explosion from the sides and above. Utility Model Content

[0005] The main objective of this invention is to provide a tire inflation explosion-proof device for heavy vehicles, which solves the problems in the prior art where locking and unlocking the tire inflation protection bracket with the tire is difficult, easily soils workers' clothes or bodies, and cannot block the side and top explosion impacts.

[0006] To achieve the above objectives, this utility model provides a heavy vehicle tire inflation and explosion-proof device, including a front baffle, an inflation port on the front baffle, and an arc-shaped baffle that can surround the upper part and left and right sides of the tire fixedly connected to the rear side of the front baffle.

[0007] Furthermore, the top of the arc-shaped baffle is movably connected to a U-shaped locking rod for engaging the arc-shaped baffle and the wheel hub. The U-shaped locking rod includes a movable rod that can rotate and slide back and forth relative to the arc-shaped baffle, and a front limit rod and a rear limit rod fixedly connected to both ends of the movable rod; the front limit rod and the rear limit rod are arranged opposite to each other in the front-back direction.

[0008] Furthermore, U-shaped locking rods are rotatably connected to the left and right sides of the arc-shaped baffle, and hooks are provided on the front baffle to support the U-shaped locking rods at the position where the arc-shaped baffle and the wheel hub are engaged.

[0009] Furthermore, a handle is provided on the front side of the front baffle, and casters are provided at the bottom of the curved baffle.

[0010] This invention, by setting up an arc-shaped baffle, can block the impact of a tire explosion from above and to the left and right sides, providing a more comprehensive and effective blockage.

[0011] This utility model, by setting a U-shaped locking rod, eliminates the need for workers to crawl under the vehicle or reach their hands under the vehicle when locking and unlocking the tire inflation and explosion-proof device of heavy vehicles to the wheel hub. The operation is simple and will not get the worker's clothes or body dirty. Attached Figure Description

[0019] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0020] Example 1

[0021] like Figures 1 to 4 As shown, a heavy vehicle tire inflation and explosion-proof device includes a front baffle 1 with an inflation port 101. An arc-shaped baffle 2, capable of surrounding the upper part and left and right sides of the tire, is fixedly connected to the rear side of the front baffle 1. A U-shaped locking rod 3 for engaging the arc-shaped baffle 2 and the wheel hub is movably connected to the top of the arc-shaped baffle 2. The U-shaped locking rod 3 includes a movable rod 301 that rotates and slides back and forth with the arc-shaped baffle 2, and a front limiting rod 302 and a rear limiting rod 303 fixedly connected to both ends of the movable rod 301. The front limiting rod 302 and the rear limiting rod 303 are arranged opposite each other in the front-rear direction. Rotating the U-shaped locking rod 3 allows the front limiting rod 302 and the rear limiting rod 303 to be engaged in front of the front baffle 1 and behind the wheel hub, respectively. After rotating the U-shaped locking rod 3 so that the rear limiting rod 303 is completely above the tire, the movable rod 301 can slide back and forth.

[0022] A handle 5 is provided on the front side of the front baffle 1, and a caster wheel 6 is provided at the bottom of the arc-shaped baffle 2.

[0023] The working principle of the U-shaped locking lever 3 is as follows:

[0024] The locking process is as follows: Figure 4 In the released state shown, push the heavy vehicle tire inflation and explosion-proof device to the bottom of the vehicle to cover the tire; then push the U-shaped locking rod 3 forward, and then rotate the U-shaped locking rod 3 so that the front limit rod 302 and the rear limit rod 303 are respectively locked in front of the front baffle 1 and behind the wheel hub, thereby completing the locking of the heavy vehicle tire inflation and explosion-proof device to the wheel hub; to prevent the explosion-proof device from being ejected when the tire explodes.

[0025] The unlocking process is as follows: First, rotate the U-shaped locking lever 3 so that the rear limit lever 303 is completely above the tire; then pull the U-shaped locking lever 3 forward so that the rear limit lever 303 is completely above the arc-shaped baffle 2; finally, pull the explosion-proof device out from under the vehicle.

[0026] Example 2

[0027] like Figure 5 As shown, Embodiment 2 also provides a heavy vehicle tire inflation explosion-proof device. The only difference between Embodiment 2 and Embodiment 2 is that: U-shaped locking rods 3 are also movably connected to the left and right sides of the arc-shaped baffle 2, and a hook 4 is provided on the front baffle 1 to support the U-shaped locking rods 3 at the position where the arc-shaped baffle 2 and the wheel hub are engaged.

[0028] The U-shaped locking rods 3 on the left and right sides and the top U-shaped locking rod 3 operate on the same principle; the hooks 4 are designed to prevent the U-shaped locking rods 3 on the left and right sides from disengaging from their locked positions under the influence of gravity.

[0029] The above embodiment, by setting the arc-shaped baffle 2, can block the impact of tire explosion in the upper and left and right side directions, and the blocking direction is more comprehensive and the effect is better.

[0030] The above embodiment, by setting a U-shaped locking rod 3, eliminates the need for workers to crawl under the vehicle or put their hands under the vehicle to lock and unlock the tire inflation and explosion-proof device of heavy vehicles to the wheel hub. The operation is simple and will not get the workers' clothes or bodies dirty.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
