[0031] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0032] refer to Figure 1 , Figure 2 and Figure 3 The present invention provides a sintering machine, including a trolley track 1 and multiple sintering trolleys 2 arranged on the trolley track 1, and also includes an auxiliary unloading tool 3 for repairing sintering trolleys 2 that are damaged in operation. When the sintering trolleys 2 are running normally, the auxiliary unloading tool 3 is in standby mode; when one of the sintering trolleys 2 is damaged and needs to be replaced, the auxiliary unloading tool 3 is used to unload the sintering material in the damaged sintering trolley 2 into the replaced sintering trolley 2.

[0033] Specifically, refer to Figures 1-6 The unloading auxiliary fixture 3 includes a support frame 31 mounted on the trolley track 1, a flap 32 rotatably connected to the support frame 31 at one end, and a hydraulic pusher cylinder 33. The support frame 31 includes four support legs 311 and connecting rods 312 connecting the four support legs 311. Support plates 313 are connected between the top ends of two support legs 311 along both sides of the sintering trolley 2. Both ends of the flap 32 are rotatably connected to the corresponding support plates 313 via rotating shafts. Support plates 314 for supporting the flap 32 are provided on the opposite sides of the two support plates 313. The height of the connecting rods 312 connecting the support legs 311 is higher than the height of the sintering trolley 2 running on the trolley track 1, allowing the bottom of the support frame 31 to pass through, ensuring the normal operation of the sintering machine. Braked casters 4 are provided at the bottom of the support frame 31, facilitating the movement of this unloading auxiliary fixture 3.

[0034] refer to Figures 1-6 The telescopic end of the hydraulic push cylinder 33 is hinged to the lower end face of the other end of the flap 32, and the main body of the hydraulic push cylinder 33 is hinged to the connecting rod 312 of the support frame 31. The hydraulic push cylinder 33 adopts an electric hydraulic push rod, model DYTF700- / 110, which is a parallel split box-type electric hydraulic push rod and is telescopic.

[0035] refer to Figures 1-6The upper surface of the flap 32 is provided with a fixing member 5 for fixing the damaged sintering trolley 2. The fixing member 5 includes a clamp 51 and a fixing bolt 52, one end of which is hinged to the flap 32. The size of the clamp 51 is adapted to the size of the actual sintering trolley wheel axle 21. The clamp 51 is engaged with the sintering trolley wheel axle 21 on the sintering trolley 2. The other end of the clamp 51 is provided with a fixing block 53. The main body of the fixing bolt 52 passes through the fixing block 53 and is threaded onto the flap 32. The number of fixing members 5 corresponds to the number of sintering trolley wheels 22. The actual number of sintering trolley wheels 22 for each sintering trolley 2 is four, so the number of fixing members 5 is also four.

[0036] refer to Figures 3-6 When the sintering machine is operating, if a sintering trolley 2 malfunctions, the faulty sintering trolley 2 will move to the unloading auxiliary workpiece location. A lifting crane will then lift the faulty sintering trolley 2 onto the tilting plate 32, and a new sintering trolley 2 will be used to replace it. At this point, the four axles 21 of the sintering trolley 2 will be locked in place by the fixing components 5. The hydraulic push cylinder 33 will then cause the tilting plate 32 and the faulty trolley on it to tilt at a certain angle. While tilted, the sintering material inside the sintering trolley 2 will be unloaded into the replacement sintering trolley 2, thus completing the auxiliary unloading. During this process, the faulty sintering trolley is firmly fixed, and the operation is stable, solving the safety problem of online sintering trolley replacement and reducing safety hazards in the working environment.

[0037] refer to Figures 3-6 The flip plate 32 is also provided with limiting grooves 6 for placing the wheels 22 of the sintering trolley 2. The number of limiting grooves 6 corresponds to the number of wheels 22 of the sintering trolley 2. Multiple anti-slip stripes 7 are provided on the inner bottom wall of each limiting groove 6. When the damaged sintering trolley 2 is placed on the flip plate 32, the wheels 22 are just stuck in the limiting grooves 6. When the flip plate 32 tilts the sintering trolley 2, the limiting grooves 6 act as a blocking and limiting force on the wheels 22, preventing the sintering trolley 2 from moving downwards in the tilted state, and further improving the firmness of the sintering trolley 2 on the flip plate 32.

[0038] refer to Figures 3-6 The upper end of the flap 32, which is hinged to the support frame 31, is provided with a limiting groove 8. A baffle 9 is installed in the limiting groove 8. The baffle 9 acts as a stop for the sintering trolley 2, further enhancing the firmness and stability of the sintering trolley 2 fixed on the flap 32. When the baffle 9 is worn or broken, it can be replaced by inserting the baffle 9 into the limiting groove 8.

[0039] In summary, the unloading auxiliary fixture 3 in this utility model can fix the faulty sintering trolley 2 and cause it to tilt and rotate at a certain angle, thereby unloading the sintering material into the replaced new sintering trolley. During this process, the faulty sintering trolley is firmly fixed and the operation is stable. This can solve the safety problem of online replacement of sintering machine trolleys, reduce safety hazards in the on-site working environment, and improve replacement efficiency.
