[0036] Reference Figure 1 Both of the moving wheels 2 are coaxially arranged with secondary driven sprockets 8, the rotating shaft 5 is fixedly sleeved with secondary driving sprockets 9 corresponding to the secondary driven sprockets 8 one by one, and secondary transmission chains 10 are sleeved between the secondary driving sprockets 9 and the corresponding secondary driven sprockets 8.

[0037] Reference Figure 1 The control system starts the motor 3, the output shaft of the motor 3 drives the primary driving sprocket 4 to rotate, the primary driving sprocket 4 drives the primary driven sprocket 6 to rotate through the primary transmission chain 7, the primary driven sprocket 6 drives the secondary driving sprocket 9 to rotate through the rotating shaft 5, the secondary driving sprocket 9 drives the secondary driven sprocket 8 to rotate through the secondary transmission chain 10, and the secondary driven sprocket 8 drives the moving wheel 2 to rotate, so that the motor 3 drives the two moving wheels 2 to synchronously and actively rotate, thereby improving the stability of the frame 1 in the overall moving process.

[0038] Reference Figure 1 and Figure 2The oil box 11 is integrally formed with the two inner side walls of the oil box 11 relative to the moving direction of the rack 1, and the oil baffle 12 is arranged on the two inner side walls. The oil baffle 12 plays a blocking role on the lubricating oil, and reduces the possibility of the lubricating oil in the oil box 11 accidentally shaking out of the oil box 11 when the rack 1 moves.

[0039] With reference to Figure 1 and Figure 2 The oil box 11 is integrally formed with the two inner side walls of the oil box 11 relative to the moving direction of the rack 1, and the oil baffle 12 is arranged on the two inner side walls. The oil baffle 12 plays a blocking role on the lubricating oil, and reduces the possibility of the lubricating oil in the oil box 11 accidentally shaking out of the oil box 11 when the rack 1 moves.

[0040] With reference to Figure 1 The oil box 11 is made of plastic, and a transparent window (not shown in the figure) is embedded at the position of the oil box 11 relative to the rack 1. Since the plastic has light transmission, the worker can directly observe the remaining amount in the oil box 11 through the transparent window, so that when the amount of lubricating oil in the oil box 11 is small, the worker can timely supplement the lubricating oil.

[0041] The implementation principle of the embodiment 1 is that the control system starts the motor 3, the output shaft of the motor 3 drives the primary driving sprocket 4 to rotate, the primary driving sprocket 4 drives the primary driven sprocket 6 to rotate through the primary transmission chain 7, the primary driven sprocket 6 drives the secondary driving sprocket 9 to rotate through the rotating shaft 5, and the secondary driving sprocket 9 drives the secondary driven sprocket 8 to rotate through the secondary transmission chain 10. The secondary driven sprocket 8 drives the moving wheel 2 to rotate, so that the motor 3 drives the two moving wheels 2 to synchronously drive rotate, thereby improving the stability of the whole moving process of the rack 1.

[0042] Embodiment 2

[0043] With reference to Figure 3 and Figure 4 The difference between the embodiment and the embodiment 1 is that the plate seat 14 is bolted on the side wall of the rack 1, the accommodating cavity 141 is vertically arranged on the plate seat 14, the guide rod 15 is vertically welded on the plate seat 14 relative to the accommodating cavity 141, and the mounting seat 16 is slidably sleeved on the guide rod 15.

[0044] The position where the mounting seat 16 is slidably sleeved on the guide rod 15 is arranged in a spindle type, so as to reduce the contact area between the mounting seat 16 and the guide rod 15, and improve the smoothness of the lifting movement of the mounting seat 16 on the guide rod 15.

[0045] With reference to Figure 3 The compression spring 17 is arranged between the bottom of the mounting seat 16 and the bottom of the accommodating cavity 141, and the pull wire 20 is extended to the outside of the rack 1.

[0046] With reference to Figure 3 and Figure 4The insertion slot 161 is vertically formed through the mounting seat 16, and opposite sides of the insertion slot 161 are matched with V-shaped positioning slots 162. The insertion rod 18 is integrally formed on the oil box 11, and the V-shaped elastic mounting sheet 19 is welded on the insertion rod 18. The elastic mounting sheet 19 is made of metal.

[0047] The elastic mounting sheet 19 is inserted and matched with the insertion slot 161 and the positioning slot 162, and the let-out slot 163 is formed on the mounting seat 16 for letting out the insertion rod 18 to realize the let-out.

[0048] The implementation principle of the embodiment 2 is that during installation, the worker pulls down the mounting seat 16 through the pull wire 20, so that the mounting seat 16 is close to the open end of the rack 1. Then the worker inserts the elastic mounting sheet 19 from the top end of the insertion slot 161 downward, and during the descending process of the oil box 11, the elastic mounting sheet 19 is deformed until it is completely moved into the positioning slot 162, and then the elastic mounting sheet 19 restores the deformation and is automatically and firmly clamped in the positioning slot 162.

[0049] After the mounting seat 16 is loosened, the compression spring 17 pushes the mounting seat 16 to ascend, the mounting seat 16 drives the oil box 11 to ascend, so that the bottom of the primary driven sprocket 6 and the secondary driven sprocket 8 is immersed in the lubricating oil. During disassembly, the elastic mounting sheet 19 is manually pulled out from the bottom of the insertion slot 161, which is convenient to operate.

[0050] The above are the preferred embodiments of the present application, and are not used to limit the protection scope of the present application. Therefore, any equivalent changes made according to the structure, shape and principle of the present application should be covered in the protection scope of the present application.
