[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0018] Example 1: Please see Figure 1-5 A ring-cooled machine trolley, comprising: The trolley body 1 has a support frame 2 fixedly connected to each of the four corners at the bottom of the trolley body 1. Each of the two ends of the bottom of the support frame 2 has a through hole 3. A rotating shaft 5 is assembled inside the through hole 3 through a ball bearing 4. The movable wheel 6 is installed at one end of the rotating shaft 5. The rotating shaft 5 has an assembly groove 7 inside. An oil distribution pipe 8 is fixedly connected inside the assembly groove 7. Multiple application pipes 9 are fixedly connected to both ends of the outer side of the oil distribution pipe 8. The oil supply assembly is mounted on the top of one side of the support frame 2 and is used to cooperate with the oil distribution pipe 8 and the application pipe 9 to lubricate the ball bearing 4. More specifically, the main body 1 of the trolley mainly includes: Trolley frame: as the main structure of the trolley, it bears the weight of the entire trolley and its load.

[0019] Drive system: including motor, reducer and transmission mechanism, used to drive the trolley body 1 to move along the track.

[0020] Material bin: Located on the trolley frame, used to load hot sintered ore.

[0021] Cooling system: includes cooling water pipes and nozzles, used to spray water to cool the sinter in the hopper.

[0022] Control system: This includes an automatic control system for controlling the start, stop, speed regulation, and cooling water spraying of the control vehicle.

[0023] After the drive system is started, the trolley body 1 moves cyclically along the closed track of the annular cooler. Hot sinter is loaded into the hopper of the trolley body 1 through the feeding device. As the trolley body 1 moves, the hot sinter in the hopper passes through the cooling zone. The cooling system sprays water onto the sinter through nozzles. The water absorbs heat and evaporates, thereby reducing the temperature of the sinter. The sinter cooled to a certain temperature moves with the trolley body 1 to the unloading position and is unloaded through the unloading device. In summary, the main body of the trolley 1 is a mature existing technology, and will not be elaborated further here; Furthermore, during the manufacturing of the trolley body 1, its side panels can be fixed on a plasma cutting machine to divide the side panels into two pieces. Then, the divided side panels are drilled and cleaned. Finally, the finished products are neatly arranged around the ring cooler to increase the contact area between the side panels and the sintered ore, and at the same time improve the operating efficiency of the equipment. In this embodiment, the bottom end of the support frame 2 is n-shaped. Through the structural characteristics of the support frame 2, the middle part of the bottom end of the support frame 2 can have space for mounting an external drive system, so as to provide rotational power for the rotating shaft 5 with the help of the external drive system. In this embodiment, the rotating shaft 5 is provided with a plurality of clearance holes, and the application tube 9 extends through the clearance holes to the outside of the rotating shaft 5; More specifically, by setting the clearance hole, there is space on the rotating shaft 5 for the application tube 9 to pass through. Since part of the application tube 9 is located in the clearance hole, the clearance hole can also provide auxiliary support for the application tube 9, thus ensuring the stability of the application tube 9 in application. In this embodiment, the end of the application pipe 9 away from the oil distribution pipe 8 is bent towards the ball bearing 4, and the bent part of the application pipe 9 is fixedly connected to the oil nozzle. More specifically, by bending the application pipe 9, the lubricating oil entering the application pipe 9 can flow to the ball bearing 4 in a concentrated manner, and with the help of the oil spray nozzle, the lubricating oil is stably applied to the ball bearing 4, thereby forming effective lubrication of the ball bearing 4.

[0024] Example 2: Please see Figure 1-5 This embodiment provides a technical solution based on Embodiment 1: the oil supply assembly includes: Oil supply pipe 10 is fixedly connected to the top of one side of the support frame 2, and the end of oil supply pipe 10 near the oil distribution pipe 8 is also rotatably connected to one end of the oil distribution pipe 8. The locking cylinder 11 is fixedly connected to the outside of the other end of the oil supply pipe 10. Multiple straight grooves 12 are provided on the outside of the locking cylinder 11. A pressure-bearing through groove 14 is provided at the end of the straight groove 12. A locking hole 13 is provided at the end of the pressure-bearing through groove 14. The sealing disc 15 has a stop rod 16 fixedly connected to one side edge of the sealing disc 15, which corresponds to the locking hole 13 one by one, and the stop rod 16 is engaged with the locking hole 13. In this embodiment, a rotary joint is fixedly connected to one end of the oil supply pipe 10 and the oil distribution pipe 8 that are close to each other, and the oil supply pipe 10 and the oil distribution pipe 8 are connected by the rotary joint. More specifically, by setting up a rotary joint, the lubricating oil inside the oil supply pipe 10 can be transferred to the inside of the oil distribution pipe 8 without affecting the rotation of the oil distribution pipe 8. In this embodiment, a stabilizing frame is fixedly connected to the top of one side of the support frame 2, and the oil supply pipe 10 is fixedly connected to one end of the stabilizing frame. More specifically, the installation of the stabilization frame enables the effective assembly of the oil supply pipe 10, greatly ensuring the stability of the oil supply pipe 10 in application.

[0025] In this embodiment, the width of the pressure-bearing groove 14 is smaller than the diameter of the locking hole 13; More specifically, when the stop rod 16 reaches the end of the linear slide groove 12, rotating the stop rod 16 causes it to approach the pressure-receiving through groove 14. When the stop rod 16 contacts the pressure-receiving through groove 14, due to the influence of size, the pressure-receiving through groove 14 will block the stop rod 16. As the sealing disc 15 continues to rotate, the pressure-receiving through groove 14 can be expanded by the stop rod 16 until the stop rod 16 reaches the inside of the locking hole 13. More specifically, in order to enable the pressure-bearing channel 14 to deform to a certain extent, the locking cylinder 11 can be made of stainless steel; In this embodiment, a sealing groove is provided on one side of the sealing disc 15, and a sealing ring is fixedly connected inside the sealing groove; More specifically, by setting the sealing gasket, after the sealing plate 15 and the oil supply pipe 10 are attached, the sealing ring can be used to seal the connection between the sealing plate 15 and the oil supply pipe 10, so as to prevent dust and other impurities from entering the oil supply pipe 10 through the connection gap between the sealing plate 15 and the oil supply pipe 10. Furthermore, the sealing ring can be an O-ring, and the material can be rubber; In this embodiment, the sealing disc 15 has multiple gripping grooves on its outer side, which allows personnel to rotate the sealing disc 15 more conveniently.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] The working principle involves connecting the drive system to the rotating shaft 5, allowing the trolley body 1 to circulate along the track of the annular cooler under the support of the rotating shaft 5. During subsequent maintenance, the sealing disc 15 is first rotated to move the stop lever 16 closer to the pressure channel 14. As the sealing disc 15 continues to rotate, the stop lever 16 expands the pressure channel 14 until it reaches the inside of the linear slide 12. Then, the sealing disc 15 is pulled outward, causing it to disengage from the locking cylinder 11, thereby releasing the blockage on the oil supply pipe 10. Lubricating oil is then injected. The lubricating oil enters the oil supply pipe 10 and flows along the oil supply pipe 10 to the oil distribution pipe 8. After being distributed by the application pipe 9, the lubricating oil can be quickly applied to the ball bearing 4 to achieve lubrication of the ball bearing 4 and reduce the wear of the rotating shaft 5. After lubrication, the stop rod 16 is aligned with the linear slide groove 12, and the sealing plate 15 is pushed to make the stop rod 16 reach the end of the linear slide groove 12. Then, the sealing plate 15 is rotated to make the stop rod 16 expand the pressure through groove 14 and engage with the locking hole 13, thereby forming a blockage of the oil supply pipe 10 with the sealing plate 15.
