Description

Technical Field

[0001] This utility model relates to the field of rubber vulcanization equipment technology, specifically to a vulcanization trolley with a quick-change wheel structure. Background Technology

[0002] Vulcanization is the final step in rubber processing, after which rubber is vulcanized into shaped, usable rubber products. The vulcanization process involves placing the product blank on a vulcanizing trolley, which is then fed into a vulcanizing furnace for vulcanization and shaping. The wheel bearings of the vulcanizing trolley are highly susceptible to damage under the high temperatures inside the furnace, leading to sealing system failure and frequent bearing replacement. Currently, the wheels of existing vulcanizing trolleys are fixed to the frame via axles, making disassembly, repair, and replacement extremely cumbersome, time-consuming, and labor-intensive. Summary of the Invention

[0003] In view of the deficiencies of the prior art, the purpose of the present invention is to provide a vulcanizing trolley with a quick-change wheel structure, which realizes the quick-change function by setting the wheels to move.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a vulcanizing trolley with a quick-change wheel structure, comprising a trolley body and a wheel assembly movably disposed on the trolley body. The bottom of the trolley body is provided with a wheel frame for assembling the wheel assembly. The wheel frame is provided with an axle hole with a bottom opening. The wheel assembly includes a wheel body, a bearing, and an axle. The bearing is disposed in the inner diameter of the wheel body, and the axle passes through the inner hole of the bearing. The axle is assembled in the axle hole of the wheel frame, and the axle is connected to the wheel frame through a connecting plate.

[0005] Furthermore, the connecting plate includes an integrally formed hanging part and a connecting part, the hanging part and the connecting part forming an L-shaped structure, the connecting part being provided with a connecting hole for connecting a fastening bolt, the fastening bolt passing through the connecting hole and being connected and fixed to the wheel axle, the connecting part overlapping the upper edge of the wheel frame.

[0006] Furthermore, the connecting hole is an oblong hole, and the fastening bolt can be moved and adjusted within the connecting hole.

[0007] Furthermore, a threaded hole for connecting the fastening bolt is provided on the axis of the wheel axle end face.

[0008] Furthermore, the connecting plate is a one-piece molded steel plate.

[0009] Furthermore, the wheel frame includes two opposing fixed plates, the wheel assembly is assembled between the two fixed plates, the two fixed plates are respectively provided with axle holes with bottom openings, the two ends of the wheel axle are respectively assembled in the two axle holes, and there are two connecting plates, which are respectively connected to the two ends of the wheel axle.

[0010] The beneficial effects of this utility model are as follows: by setting axle holes with bottom openings on the wheel frame, the wheel assembly can be quickly disassembled and installed from the bottom of the vulcanizing trolley. The wheel rolls on the track, and the support force provided by the track to the wheel restricts the axle in the axle hole. In order to prevent the wheel from falling off the track due to vibration during the movement of the vulcanizing trolley, the axle is connected to the wheel frame by a connecting plate. The connecting plate is set on the outside of the wheel frame for easy disassembly. Attached Figure Description

[0016] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] See appendix Figure 1-4A vulcanizing trolley with a quick-change wheel structure includes a trolley body 1 and a wheel assembly movably mounted on the trolley body 1. The bottom of the trolley body 1 has a wheel frame 2 for assembling the wheel assembly. The wheel frame 2 has a bottom-opening axle hole 3. The wheel assembly includes a wheel body 4, a bearing 5, and an axle 6. The bearing 5 is disposed within the inner diameter of the wheel body 4, and the axle 6 passes through the inner hole of the bearing 5. The axle 6 is assembled into the axle hole 3 of the wheel frame 2 and is fixedly connected to the wheel frame 2 via a connecting plate 7. The connecting plate 7 includes an integrally formed abutment 701 and a connecting portion 702, which form an L-shaped structure. The connecting portion 702 has a connecting hole 8 for connecting fastening bolts 9, which pass through the connecting hole 8 and are fixedly connected to the axle end face. The connecting portion 702 overlaps the upper edge of the wheel frame 2.

[0018] Based on the above technical solution, to facilitate the replacement and maintenance of the trolley wheels and bearings, the trolley wheel axle is currently installed with an n-port connection to the trolley body. While this installation method facilitates the disassembly and assembly of the trolley wheels, it also significantly reduces their stability. This can lead to wheel derailment or loss of stability during trolley operation due to vibrations, bumps, or impacts at the track connection point. By incorporating an L-shaped connecting plate 7, the ease of disassembly and assembly is maintained while simultaneously increasing the stability of the trolley wheels, thus ensuring the safety of personnel and products.

[0019] Furthermore, in order to facilitate the adjustment of the connection position between the fastening bolt 9 and the connecting plate 7, so that the connecting part 702 of the connecting plate can overlap the upper edge of the wheel frame 2, the connecting hole 8 is an oblong hole, and the fastening bolt 9 can be moved and adjusted within the connecting hole 8.

[0020] Furthermore, the connecting plate 7 is a one-piece steel plate.

[0021] Furthermore, the wheel frame 2 includes two opposing fixed plates, the wheel assembly is assembled between the two fixed plates, the two fixed plates are respectively provided with axle holes 3 with bottom openings, the two ends of the wheel axle 6 are respectively assembled in the two axle holes 3, and there are two connecting plates, the two connecting plates respectively fix the two ends of the wheel axle 6.

[0022] In this embodiment, the wheel assembly is designed to be movably connected to the main body of the trolley, facilitating its disassembly and assembly from the bottom of the trolley. During loading and unloading from the chassis and tracks, vibrations may cause the wheel assembly to detach, leading to derailment and threatening personnel safety and product quality. The connecting plate 7 provides support for the wheel assembly, preventing the axle 6 from falling through the bottom opening of the axle hole 3 and causing derailment. The connecting plate 7 is made of L-shaped stainless steel and is fixed to the center of the trolley wheel axle and the wheel frame of the trolley main body using fastening bolts 9. This prevents the wheel from detaching during vibration and facilitates wheel disassembly, replacement, and bearing maintenance. The L-shaped design of the connecting plate 7 allows it to be directly hung on the wheel frame 2 without the need for fasteners.
