[0020] This embodiment is a safety baffle for the tires of mechanical equipment. During the process of inflating the tires of mechanical equipment, etc., it is set in front of the tire to prevent the compressed air from hitting the tire rubber when the tire explodes, and the tire rubber hits the baffle clamping steel pipe. The clamping steel pipe drives the entire tire baffle to lean inward through the inner steel pipe, making the tire baffle lean more inward while blocking the impact of the snap ring, nut and other items from hitting the maintenance personnel outward. As Figure 1 , 2 , as shown in Figures 3, 4, and 5, the safety baffle for the tires of this mechanical equipment includes a tire baffle 100 arranged on the outside of the tires of the mechanical equipment, and a detachable movable shaft 200 that fixes the tire baffle 100 to the outside of the tires of the mechanical equipment from the front and back sides; the tire baffle 100 is formed by a support skeleton 110 supporting a retaining net 120 to form a vertical baffle with left and right top corner bevels 140, and an air release installation hole 130 is provided at the center of the tire baffle 100 corresponding to the wheel hub of the mechanical equipment tire. A handle 150 is also provided on the tire baffle 100. The handle 150 is arranged above the air release installation hole 130, and when moving, the handle 150 can be held by hand to move the tire baffle 100 away from the detachable movable shaft 200.

[0021] In this embodiment, the retaining net 120 in the tire baffle 100 uses a 2 - mm - thick iron net, with a width of 1500 mm and a height of 1400 mm. The left and right top corner bevels are 300 mm × 300 mm, and a Φ600 - mm air release installation hole 130 is left in the middle. The hole of the air release installation hole 130 needs to be edge - wrapped, and the distance from the lower edge of the air release installation hole 130 to the baffle is 300 mm. The support skeleton 110 also uses a steel - bar square tube. The bottom square tube is made of a 3 - mm - wall - thickness 40 mm × 40 mm × 1500 - mm C - shaped steel pipe, and the other square tubes are welded with a 2 - mm - wall - thickness cross - section of 40 mm × 40 mm. The handle 150, also known as a push - pull handrail, is made of a Φ40 - mm round steel pipe, about 800 mm long and 100 mm high. The installation height is about 1200 mm from the ground, generally above the air release installation hole 130.

[0022] In this embodiment, two detachable movable shafts 200 are used to support both ends of the tire baffle 100. As Figure 6 and Figure 7 shown, the detachable movable shaft 200 is composed of an inner tube 210 and an outer tube 220 to form an axially telescopic structure. A tire clamping rod 230 perpendicular to it is provided at the end of the inner tube 210; a baffle fixing clip 240 for installing the tire baffle 100 is provided at the front end of the outer tube 220, and the tire baffle 100 is fixedly installed on this clip 240. In addition, a pair of heavy rollers 250 are provided below the outer tube 220, and a support frame 260 is also provided near the heavy rollers 250. A universal wheel 241 is also provided in the baffle fixing clip 240.

[0023] In this embodiment, the two detachable movable shafts 200 are both made of steel pipes. In fact, metal or non-metal pipes with relatively high strength such as stainless steel pipes can be used. The steel pipe of the outer pipe 220 is made of a steel pipe with a wall thickness of 5 mm, an outer diameter of 55 mm, an inner diameter of 45 mm, and a length of 600 mm. The steel pipe of the inner pipe 210 is made of a steel pipe with a wall thickness of 5 mm, an outer diameter of 30 mm, an inner diameter of 20 mm, and a length of 800 mm. The steel pipe for making the tire clamping rod 230 is made of a steel pipe with a wall thickness of 3 mm, a size of 40 mm×20 mm×300 mm.

[0024] The two heavy rollers 250 below the outer pipe 220 are also called movable support wheels. They are 3-inch heavy-duty rolling wheels, with a directional wheel in the front and a universal wheel in the rear. The heavy rollers 250 are connected to the bottom plate made of 5.5-mm thick steel plate by screws to facilitate the replacement of the rollers in the future. In addition, the inner pipe 210 and the outer pipe 220 are fixed by a linear bearing 121. The model of this linear bearing 121 can be selected as LM30. Pulleys and fixed blocks are installed on the movable shaft to adjust the width between the two detachable movable shafts.

[0025] By using the safety baffle for the mechanical equipment tire of this embodiment, when the tire explodes, it can be avoided that the compressed air impacts the tire rubber, the tire rubber impacts the baffle clamping steel pipe, and the clamping steel pipe drives the whole tire baffle to lean inward through the inner steel pipe, so that while the tire baffle leans more inward, it blocks the impact of the snap ring, nut and other items outward to injure the maintenance personnel.

[0026] In addition, in this embodiment, the mesh design of the tire baffle can effectively discharge the compressed air, reduce the deformation of the baffle caused by the instantaneous air pressure expansion of the baffle, and play an effective protective role for the maintenance personnel.

[0027] The design features of the safety baffle for the mechanical equipment tire of this embodiment: simple in design and manufacture, easy to move, and the opening width of the movable and detachable movable shafts can be adjusted to adapt to the safety inspection of various tire models. The detachable movable shaft is designed: convenient for handling and making one baffle suitable for various tire models.

[0028] In practice, in this embodiment, the inner pipe 210 can extend to the leftmost end of the outer pipe 220, as Figure 7As shown, a bearing 121 is provided at the right end where the inner tube 210 can extend into the outer tube 220 and is then fixed to the coupling 124 with a countersunk head bolt 126. In this way, it is convenient for the relative rotation between the inner tube 210 and the outer tube 220, supports the inner tube 210, and facilitates the rotation of the inner tube 210 within the outer tube 220. At the right end inside the outer tube 220, it is connected to the inner tube 210 by means of a coupling 124. Here, the coupling 124 is used for the engagement of the locking teeth to ensure that the tire clamping rod 230 clamps the tire during gas filling. A spring 122 is used to ensure the engagement state of the locking teeth of the coupling 124. Here, the original length of the spring 122 is 100 mm, and the current design is 70 mm. There is a handle 125 at the end of the outer tube 220 for pulling the inner tube to the left to compress the spring 122, disengaging the locking teeth of the coupling 124, and then rotating the inner tube 210. After rotating 90 degrees, release it, and use the locking teeth of the coupling 124 to re-engage to prevent the tire clamping rod 230 from clamping the tire.

[0029] In some other embodiments, countersunk head screws 126 and a fixed shaft clamping position 127 are adopted. For example, when the inner tube extends to the leftmost end, it is then fixed to the coupling 124 with a countersunk head screw 126, and the fixed shaft clamping position 127 can be cancelled. However, the inner diameter of the coupling needs to be enlarged to 31 mm (to facilitate sleeving the inner tube). The spring 122 is sleeved on the inner tube 210, and a snap ring is used to give a certain compression amount to the spring 122. The left side of the coupling 124 is fixed to the inner tube 210 with a countersunk head screw, and the other side is directly welded to the outer tube 220.
