Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 2 As shown, an auxiliary disassembly device for horizontal wheel bearings of a large vehicle provided by an embodiment of the utility model comprises an I-shaped support plate 1 and four support rods 2 arranged on one side of the I-shaped support plate 1, the four support rods 2 are respectively arranged at the four ends of the I-shaped support plate 1, the support rods 2 are fixedly connected to the I-shaped support plate 1 and are perpendicular to the I-shaped support plate 1, a locking piece 3 is arranged on the top end of the support rod 2 in the vertical direction, and the locking piece 3 matches the radial through holes at the four ends of the horizontal wheel bearing seat of the large vehicle; when disassembling the horizontal wheel bearing of the large vehicle, the horizontal wheel bearing seat of the large vehicle is locked and connected with the four support rods 2 through the locking piece 3, and the axis of the horizontal wheel bearing of the large vehicle and the center point of the I-shaped support plate 1 are arranged on the same axis in the vertical direction.

[0024] The utility model discloses a horizontal wheel bearing auxiliary disassembly device for a trolley, which can fix the horizontal wheel bearing seat and the support rod 2 of the trolley through the locking member 3 during disassembly, and cooperates with the external pressure applied to the I-beam support plate 1 by the jack, so that the horizontal wheel bearing of the trolley can be easily and quickly removed from the horizontal wheel bearing seat of the trolley, thus avoiding deformation of the horizontal wheel of the trolley itself during disassembly due to knocking and possible safety hazards during the disassembly process, and has low manufacturing cost and strong practicality.

[0025] Specifically, the I-beam support plate 1 in the embodiment of the utility model is obtained by welding small-sized metal plates at four ends of a rectangular metal plate. In actual engineering applications, the I-beam support plate 1 can also be adjusted and replaced accordingly according to different sizes of horizontal wheel bearing seats of large vehicles to meet actual needs.

[0026] Preferably, a plurality of reinforcing ribs 4 are fixed to the other side of the I-shaped support plate 1 in the embodiment of the utility model.

[0027] The reinforcing ribs 4 fixed on the I-shaped support plate 1 can enhance the tensile properties of the I-shaped support plate 1, improve the toughness of the structure, increase the bearing capacity, and extend the durability of the structure, so that the I-shaped support plate 1 can better resist external loads and environmental influences, reduce damage and aging, thereby ensuring the stability and reliability of the structure.

[0028] Preferably, the reinforcing ribs 4 in the embodiment of the utility model have two and are arranged in an X shape.

[0029] The two reinforcing ribs 4 are arranged in an X-shape and cross each other, which can effectively enhance the force uniformity and stability of the I-shaped support plate 1 .

[0030] Preferably, the intersection of the two reinforcing ribs 4 in the embodiment of the utility model is located at the center point of the I-shaped support plate 1 .

[0031] When the center point coincides with the intersection point, the pressure applied by the jack can be well distributed on the I-shaped support plate 1 through the reinforcing ribs 4 to prevent the I-shaped support plate 1 from being deformed due to uneven force.

[0032] Preferably, the size of the I-shaped support plate 1 in the embodiment of the utility model is the same as the size of the horizontal wheel bearing seat of the trolley.

[0033] When disassembling horizontal wheel bearings of different sizes, the I-beam support plate 1 is the same size as the horizontal wheel bearing seat of the truck, which can reduce errors and mismatches, so that operators do not need to spend extra time and energy to match devices of different sizes, thereby reducing errors during operation.

[0034] Preferably, the length of the support rod 2 in the embodiment of the utility model is the same as the length of the horizontal wheel bearing of the trolley.

[0035] When the trolley horizontal wheel bearing seat is prepared for disassembly using a disassembly device, the support rod 2 is connected through the radial through holes at the four ends of the trolley horizontal wheel bearing seat. When the length of the support rod 2 is the same as the length of the trolley horizontal wheel axle, the end point of the trolley horizontal wheel bearing can be exactly in contact with the center point of the I-beam support plate 1, so that the distance between the two can be optimally matched, ensuring the stability and balance of the support.

[0036] Preferably, the support rod 2 in the embodiment of the utility model is in the shape of a hexagonal prism as a whole.

[0037] The hexagonal prism shape has a greater load-bearing capacity than the cylindrical shape, and the six flat sides can evenly distribute the external load-bearing capacity, reduce the possibility of deformation and damage of the support rod 2, and be more stable.

[0038] Preferably, the locking member 3 in the embodiment of the utility model comprises a bolt 301 and a nut 302 , the nut portion of the bolt 301 is fixedly connected to the support rod 2 , and the nut 302 is screwed together with the bolt 301 via a thread.

[0039] The advantages of using the bolt 301 and the nut 302 as the locking member 3 are that they provide reliable connection performance, have certain adjustability and are easy to install and maintain, are reusable and widely applicable, and reduce costs.

[0040] Preferably, the I-shaped support plate 1 and the support rod 2 in the embodiment of the utility model are both made of high manganese steel.

[0041] Compared with other alloys, the advantage of high manganese steel as a material for the I-beam support plate 1 and the support rod 2 is its excellent wear resistance and impact resistance, which can extend the life of components and improve the reliability of the device.

[0042] Preferably, the connection between the support rod 2 and the I-shaped support plate 1, and the connection between the locking member 3 and the support rod 2 in the embodiment of the utility model are both welding.

[0043] The application of welding connection between the support rod 2 and the I-shaped support plate 1, and the locking member 3 and the support rod 2 has multiple advantages, including high strength, simplicity and speed, beautiful appearance, wide versatility, strong corrosion resistance and reduced maintenance costs.

[0044] It can be seen that the utility model is a kind of auxiliary disassembly device for the horizontal wheel bearing of the large vehicle. During disassembly, the horizontal wheel bearing seat of the large vehicle can be fixed to the support rod 2 by the locking piece 3. With the external pressure applied to the I-beam support plate 1 by the jack, the horizontal wheel bearing of the large vehicle can be easily and quickly removed from the horizontal wheel bearing seat of the large vehicle, thus avoiding deformation of the horizontal wheel of the large vehicle itself during knocking and disassembly and possible safety hazards during the disassembly process. The production cost is low and the practicability is strong.
