[0002] With the rapid development of modern logistics, high-lift storage equipment such as reach trucks and pallet stackers are widely used in warehouse management due to their efficient operational performance. However, in actual operation, these vehicles, due to their unique structural characteristics, are prone to rollover at full speed, especially during sharp turns. This is a problem similar to that faced by traditional counterbalanced forklifts. Especially during high-level stacking operations, the vehicle needs to perform forward, backward, and tilting movements, which increase the risk of vehicle sway and further increase the possibility of rollover. Therefore, to ensure operator safety and cargo transportation reliability, it is particularly important to conduct effective dynamic stability testing on these storage vehicles.

[0003] Among existing solutions, Chinese patent CN201220430462.3 discloses a dynamic stability test auxiliary tool for forklifts, which uses a fixed frame, a clamp, and a support frame to enhance the stability of the forklift during rapid turns. This design mainly relies on installing the tool on the forklift's overhead guard and using a crossbeam and front and rear legs to achieve a stable connection. However, this solution is not suitable for all types of warehouse vehicles, especially those that do not have an overhead guard or whose overhead guard structure is significantly different from that of traditional counterbalanced forklifts. The above method is difficult to apply directly. In view of this, the present utility model aims to provide a dynamic stability test auxiliary tool for warehouse vehicles. Utility Model Content

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] See also Figure 1-9 In an embodiment of the present invention, a dynamic stability test auxiliary tooling for a warehouse vehicle includes a first fixed bracket 200 and a second fixed bracket 300 provided on the warehouse vehicle door frame. The first fixed bracket 200 and the second fixed bracket 300 have the same structure and are symmetrically provided on both sides of the warehouse vehicle door frame. Under the action of the first fixed bracket 200 and the second fixed bracket 300, the lateral stability of the entire vehicle is improved, which helps to reduce the risk of rollover caused by uneven load distribution or rapid turning. The first fixed bracket 200 and the second fixed bracket 300 are fixed to the warehouse vehicle door frame by a top fixing mechanism 100 and a splint mechanism 400. The structure of the top fixing mechanism 100 is L-shaped, and can also be U-shaped or other shapes that are compatible with the door frame. It can be adjusted according to the different shapes of the warehouse vehicle. With the same door frame structure, different structural methods are selected for fixing, and the splint mechanism 400 is used in conjunction with the top fixing mechanism 100 to further ensure the stability of the connection between the fixed bracket and the door frame; the first fixed bracket 200 includes a bracket welding body 220 and a fixing component 210 provided on the bracket welding body 220 and connected to the warehouse vehicle door frame. An adjustable support leg component 230 is also installed on the bracket welding body 220. The fixing component 210 can be used to fix the position of the top fixing mechanism 100 so that the two are stably connected together, and the adjustable support leg component 230 can adjust the height as needed to ensure that it is always in contact with the ground to provide additional support. When the warehouse vehicle is driving, the ground clearance of the fork does not exceed 300mm, so the fork will not contact the splint mechanism 400 when lifting.

[0034] See also Figure 4 In one embodiment, in this embodiment, preferably, the fixing assembly 210 includes an upper plate 211 and a bottom plate 213, and the upper plate 211 and the bottom plate 213 are connected by a rotating shaft 212, and the bottom plate 213 is fixed on the bracket welding body 220, wherein the bottom plate 213 is welded to the end of the rotating shaft 212 and connected to its inner ring, and the upper plate 211 is directly sleeved on the outer circumference of the rotating shaft 212 and connected to its outer ring, ensuring that the upper plate 211 can rotate 360° on the rotating shaft 212 to meet the installation requirements of door frames with different structures.

[0035] See also Figure 5In one embodiment, in this embodiment, preferably, the bracket welding body 220 includes a bracket support beam 222 and a first connecting plate 221 and a second connecting plate 223 arranged on the bracket support beam 222. The first connecting plate 221 is connected to the base plate 213, and the second connecting plate 223 is connected to the clamping mechanism 400. A support sleeve 224 is also installed on the bracket support beam 222. A plurality of mounting holes are provided on the first connecting plate 221 and the second connecting plate 223. By selecting different mounting hole positions, it can be suitable for door frames of different sizes.

[0036] See also Figure 6 In one embodiment, in this embodiment, preferably, the adjustable support leg assembly 230 includes a support leg mounting plate 233 connected to the upper end of the support sleeve 224, and the support leg mounting plate 233 is penetrated by an adjustable screw 231 from top to bottom. The adjustable screw 231 is installed with an adjusting nut 232 located above the support leg mounting plate 233 and is connected to the threaded structure of the transition plate 234. The transition plate 234 is connected to the mounting bracket 235 by bolts. The mounting bracket 235 is arranged inside the support sleeve 224, and a tire 236 is installed at the end of the mounting bracket 235 away from the transition plate 234. By rotating the top side structure of the adjustable screw 231, the adjustable screw 231 rotates inside the support sleeve 224. Since the boss structure of the adjusting nut 232 located above the support leg mounting plate 233 and the adjustable screw 231 below it limits the position of the adjustable screw 231, the height of the adjustable screw 231 relative to the support sleeve 224 will not change during the rotation process. However, since the adjustable screw 231 is threadedly connected to the transition plate 234 and the mounting frame 235 cannot rotate in the support sleeve 224, the transition plate 234 moves as the screw thread rotates, and the mounting frame 235 mechanically connected to it also moves in the vertical direction, thereby affecting the height of the tire 236 from the ground.

[0037] See also Figure 7 In one embodiment, in this embodiment, preferably, the splint mechanism 400 includes two symmetrically designed splints 410, which are fastened and fixed by screws 420 and nuts 430. Under the action of the screws 420 and nuts 430, splints 410 with different spacings can be fastened. Sponge pads 440 are installed on the opposite sides of the two splints 410. In order to avoid damaging the outer surface of the portal frame channel steel, sponge pads 440 are placed on the inner sides of the two splints 410 to avoid mechanical scratches.
