Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-4 As shown, this utility model provides a technical solution: an online automatic oil injection device for sintering trolley wheels, including a fixed device 1, a moving device 2 and an oil injection device 3.

[0019] Reference Figure 1 The fixing device 1 includes a base 11. In this embodiment, the base 11 is preferably a rectangular base, which is fixed to the corresponding position on the ground. Fixing frames 12 are provided on both sides of the long side of the base 11. Here, the fixing frame 12 is preferably a U-shaped frame with the opening facing downward, and the long side of the horizontal section of the fixing frame 12 is perpendicular to the long side of the base 11.

[0020] Reference Figure 1The fixing device 1 also includes a directional component 13. There are two directional components 13, which are symmetrically arranged along the direction of material travel. The directional component 13 includes a fixing seat 131 and a directional rod 132. Here, the long side of the fixing seat 131 is parallel to the long side of the base 11. The positioning rod is located inside the fixing seat 131. The long side of the directional rod 132 is parallel to the long side of the fixing seat 131. The directional rod 132 and the fixing seat 131 are fixedly connected.

[0021] Reference Figure 1 and Figure 3 The moving device 2 includes a triggering component 21, which is mounted on a fixed frame 12 near the front end of the material travel direction. The triggering component 21 includes a mounting frame 211, a support frame 212, a contact roller 213, and a first sensor 214. The long side of the mounting frame 211 is horizontal and perpendicular to the material travel direction. The mounting frame 211 and the fixed frame 12 are fixedly connected. The support frame 212 is preferably a U-shaped frame. The support frame 212 is rotatably connected to the mounting frame 211 by means of a rotating shaft. The rotation axis of the support frame 212 is parallel to the long side of the mounting frame 211. The contact roller 213 is rotatably connected to the support frame 212. The rotation axis of the contact roller 213 is parallel to the rotation axis of the support frame 212. The first sensor 214 is mounted on the mounting frame 211 and is located on the side of the rotation axis of the support frame 212 near the rear end of the material travel direction.

[0022] Reference Figure 3 The contact roller 213 can abut against the wheel, and when the support frame 212 rotates, the contact roller 213 abuts against the first sensor 214.

[0023] When the wheel passes the mounting bracket 211, it drives the contact roller 213 to rotate. The contact roller 213 then comes into contact with the first sensor 214, which transmits a signal to the control center, reporting that the wheel has entered the oiling station. After the contact roller 213 contacts the wheel, it rotates along the mounting bracket 211 and returns to its initial position after passing the wheel. When the wheel moves in the opposite direction, the contact roller 213 does not contact the first sensor 214, and thus the function of the first sensor 214 cannot be activated.

[0024] Reference Figure 1 and Figure 2 The mobile device 2 also includes a mounting plate 22. In this embodiment, the mounting plate 22 is preferably a rectangular plate. The bottom of the mounting plate 22 is provided with guide blocks 23. There are two guide blocks 23. The two guide blocks 23 are located on both sides of the material travel direction. The guide blocks 23 and the mounting plate 22 are fixedly connected. Here, the guide blocks 23 are provided with guide grooves. The guide grooves are used to accommodate the directional rod 132, so that the mounting plate 22 can slide along the directional rod 132.

[0025] Reference Figure 1 and Figure 2 The mobile device 2 also includes a contact component 24, which includes a first drive component 241, a guide arm 242, a roller 243, and a second sensor 244. In this embodiment, the first drive component 241 is preferably a motor screw mechanism. The driving direction of the first drive component 241 is perpendicular to the long side direction of the base 11. The first drive component 241 is mounted on the mounting plate 22. The guide arm 242 is mounted on the output end of the first drive component 241 and is connected to the output end of the first drive component 241. The roller 243 is rotatably connected to the guide arm 242. The rotation axis of the roller 243 is parallel to the driving direction of the first drive component 241. The second sensor 244 is fixedly connected to the guide arm 242, and the first sensor 244 and the second sensor 244 are signal-connected.

[0026] The first sensor 214 transmits a working signal to the first drive assembly 241. The first drive assembly 241 operates and pushes out the guide arm 242. Here, the roller 243 abuts against the wheel. The roller 243 can effectively reduce the friction between the wheel and the guide arm 242. The second sensor 244 is used to sense the position of the wheel.

[0027] Reference Figure 1 The mobile device 2 also includes a reset assembly 25, which includes a second drive assembly 251, a support plate 252, and an abutment plate 253. Here, the second drive assembly 251 is preferably a motor screw mechanism. The driving direction of the second drive assembly 251 is perpendicular to the long side of the base 11. The second drive assembly 251 is mounted on the base 11. The support plate 252 is mounted on the output end of the second drive assembly 251. The support plate 252 is horizontally arranged, and the abutment plate 253 is vertically arranged. The abutment plate 253 is located on the side of the support plate 252 near the rear end of the material travel direction. The abutment plate 253 is fixedly connected to the support plate 252, and the abutment plate 253 can abut against the mounting plate 22.

[0028] Reference Figure 2 The moving device 2 also includes an air slide block 254, which is fixed to the side of the base 11 near the rear end of the material travel direction, and the air slide block 254 can abut against the mounting plate 22.

[0029] Reference Figure 1 , Figure 2 and Figure 4The oil injection device 3 includes a third drive assembly 31, a positioning frame 32, an oil supply pipe 33, and a spring 34. In this embodiment, the third drive assembly 31 is preferably a motor screw mechanism. The driving direction of the third drive assembly 31 is perpendicular to the long side of the base 11. The third drive assembly 31 is mounted on the mounting plate 22. The third drive assembly 31 is located on the rear side of the guide arm 242 near the material travel direction. The positioning frame 32 is mounted on the output end of the third drive assembly 31. Here, the positioning frame 32 is preferably a U-shaped frame. The long side of the two vertical parts of the positioning frame 32 is parallel to the material travel direction. The oil supply pipe 33 passes through the two vertical parts of the positioning frame 32 in sequence and is slidably connected to the positioning frame 32. The spring 34 is sleeved on the oil supply pipe 33 and is fixedly connected to the positioning frame 32.

[0030] Referring to the figure, the infusion tube is equipped with a sensor bracket 35 and a positioning sensor 36. Here, the sensor bracket 35 and the positioning frame 32 are fixedly connected. A positioning sensor is installed at the sensor bracket 35, and the positioning sensor 36 is fixedly connected to the oil infusion tube 33. When the oil infusion tube 33 slides, it drives the positioning sensor 36 to slide. The positioning sensor provides a contact signal to the positioning sensor 36 and performs the oil injection operation.

[0031] The working principle of an online automatic oil injection device for sintering trolley wheels is as follows: The vehicle first squeezes the contact roller 213 and makes the contact roller 213 abut against the first sensor 214. The first sensor 214 controls the guide arm 242 to slide through the first drive assembly 241. The wheel abuts against the roller 243. The setting of the roller 243 can effectively reduce the friction between the wheel and the guide arm 242. Then it contacts the second sensor 244 to confirm that the wheel has reached the preset position, and then drives the mounting plate 22 to slide. The oil injection pipe extends, and the spring 34 prevents the oil injection pipe from making rigid contact with the wheel, thus avoiding damage. Then, the oil injection operation is carried out for 6 seconds through the oil injection pipe. After the oil injection is completed, the guide arm 242 is retracted, the second drive assembly 251 drives the support plate 252 to slide, and at the same time, the abutment plate 253 drives the mounting plate 22 to return to its original position and prepare for the second injection.
