DETAILED DESCRIPTION
[0020] The present invention will be further described below by way of examples with reference to the accompanying drawings.
[0021] Refer to the attached Figure 1-6A surfacing composite furnace roller for conveying steel billets comprises a bottom plate 1, a transmission roller 2, a protective shell 3, a support sleeve 4, a limit ring 5, a support plate 7, a bearing seat 9 and a fixed plate 18. One end of the transmission roller 2 is arranged on the support plate 7 through the bearing seat 9, and the other end of the transmission roller 2 is rotatably connected to the fixed plate 18 through a semicircular needle roller bearing 19. The support plate 7 and the fixed plate 18 are respectively fixed on the bottom plate 1, and the transmission roller 2 is connected to the driving assembly; a protective shell 3 is provided on the outside of the transmission roller 2, a support sleeve 4 matched with the protective shell 3 is provided at one end of the transmission roller 2, and a limit ring 5 matched with the protective shell 3 is provided at the other end of the transmission roller 2.
[0022] In this embodiment, refer to the attached Figure 1-6 A transmission roller 2 is arranged on the top of the bottom plate 1, a protective shell 3 is provided on the surface of the transmission roller 2, and a driving component is arranged on one side of the transmission roller 2, and the transmission roller 2 is rotated by the driving component;
[0023] The protective shell 3 is installed through a fixing assembly, which includes a support sleeve 4 and a limiting ring 5. The support sleeve 4 is fixed to one side of the protective shell 3, and the limiting ring 5 is located on the other side of the protective shell 3. The limiting ring 5 is fixed on the transmission roller 2. Fixing screws 6 are provided on the top and bottom of the support sleeve 4, and the protective shell 3 is installed and fixed through the fixing assembly.
[0024] Specifically, the inner diameter of the support sleeve 4 and the protective shell 3 is the same as the diameter of the transmission roller 2, which can ensure that the protective shell 3 moves left and right on the surface of the transmission roller 2. The limiting ring 5 is fixed to the surface of the transmission roller 2 to limit the left and right movement of the protective shell 3. There are two fixing screws 6, which can be fixed to the transmission roller 2 through the upper and lower positions of the support sleeve 4.
[0025] See also Figure 1-6 , a limiting assembly is provided on the bottom plate 1, and the driving roller 2 is installed through the limiting assembly. The limiting assembly includes a support plate 7, which is fixed to the top of the bottom plate 1, and a limiting groove 8 is provided on the top of the support plate 7. A bearing seat 9 is sleeved on the surface of the driving roller 2. The bearing seat 9 is in the shape of a cube and has the same diameter as the limiting groove 8. When the bearing seat 9 moves up and down, it can be inserted into the limiting groove 8. A fixing block 10 is fixedly connected to the top of the bearing seat 9, and a limiting screw 11 is provided on one side of the support plate 7. The limiting screw 11 passes through the support plate 7 and is threadedly connected to the fixing block 10.
[0026] The surface of the driving roller 2 is fixedly connected to the limiting plate 12 , and one side of the fixing screw 6 passes through the supporting sleeve 4 and is threadedly connected to the driving roller 2 .
[0027] Specifically, the function of the limiting screw 11 is to fix the bearing seat 9 and connect the transmission roller 2 with the support plate 7. There are six limiting plates 12, which are evenly fixed on the surface of the transmission roller 2. A corresponding slot is opened inside the protective shell 3. Through the cooperation between the limiting plate 12 and the slot, the power of the transmission roller 2 can be transmitted to the protective shell 3.
[0028] See also Figure 1-6 The driving assembly includes a pin shaft 13, which is fixed to one side of the driving roller 2. A driving rod 14 is movably connected to the surface of the pin shaft 13, and a sprocket 15 is fixedly connected to the surface of the driving rod 14. A chain 16 is sleeved on the surface of the sprocket 15, and the chain 16 is connected to an external driving device. The driving force is transmitted through two sets of sprockets 15 and chains 16 to achieve the function of driving the driving roller 2 to rotate. A support seat 17 is sleeved on the surface of the driving rod 14, and the bottom of the support seat 17 is fixedly connected to the bottom plate 1. A fixed plate 18 is set at the bottom of the driving roller 2, and a semicircular needle roller bearing 18 is fixedly connected inside the fixed plate 18.
[0029] Specifically, the support seat 17 is used to support the transmission rod 14 to improve the stability of the transmission rod 14 when it rotates. A semicircular needle roller bearing 19 is fixed inside the fixed plate 18. The semicircular needle roller bearing 19 can withstand radial loads, axial loads and combined loads. Through the rolling motion of the needle roller, the bearing can effectively support the load from the transmission roller 2, so that the transmission roller 2 can run smoothly. The protective shell 3 is made of tungsten carbide alloy. Tungsten carbide alloy is a very hard material with excellent wear resistance and high temperature resistance, which can significantly extend the service life of the furnace roller.
[0030] The working principle of the utility model is as follows: when the protective shell 3 needs to be disassembled and replaced, the staff uses an external tool to remove the limit screw 11, cancel the limit on the bearing seat 9, and then lift the support sleeve 4 upward to make the transmission roller 2 rotate with the pin shaft 13 as the axis. Figure 4 As shown, the two sets of fixing screws 6 on the surface of the support sleeve 4 are then removed to cancel the fixing of the support sleeve 4, and then the protective shell 3 is moved to the right to completely separate the protective shell 3 from the transmission roller 2, as shown in FIG. Figure 5 As shown, the protective shell 3 can be quickly disassembled to facilitate maintenance, and then the new protective shell 3 is moved to the surface of the driving roller 2 to replace the driving roller 2 to transport the steel billet, thereby improving the processing efficiency.
