[0009] As a further improvement to the above solution, a connecting plate for installing live bolts is provided on the lower rear side of the lifting seat, and at least one limiting plate is provided above the connecting plate, with a limiting hole for the transmission chain to pass through.

[0010] As a further improvement to the above solution, at least one mounting ring is provided on the side of the mounting bracket, and an L-shaped stop bar is installed inside the mounting ring. The L-shaped stop bar has a horizontal section and a vertical section. The vertical section of the L-shaped stop bar is rotatably inserted into the mounting ring, and the horizontal section of the L-shaped stop bar can be rotated to the bottom of the lifting seat to prevent the lifting seat from sliding down.

[0011] As a further improvement to the above scheme, at least two mounting rings are provided.

[0016] The beneficial effects of this utility model are:

[0017] Compared with existing technologies, this utility model uses a vehicle body, lifting seat, and insert rod to transport the material box containing NdFeB into the NdFeB sintering furnace. The jack, drive chain, and sprocket work together to control the lifting and lowering of the insert rod, thus achieving the purpose of loading and unloading the material box. The horizontal guide wheel and guide plate guide the vehicle body, aligning it with the sintering furnace. This allows the front of the vehicle body to smoothly enter the space under the sintering furnace base, while simultaneously allowing the insert rod and its loaded material box to be smoothly delivered into the middle of the furnace body. The first positioning sleeve positions the material box during loading, ensuring that the material box is always in place during each loading process. The first positioning sleeve is positioned at a predetermined location on the insertion rod, avoiding the need for manual judgment and adjustment, which increases the workload of workers and prolongs the furnace loading time. The second positioning sleeve works in conjunction with the first positioning sleeve. By combining the actual insertion depth of the insertion rod with the position of the first positioning sleeve on the insertion rod and the position of the material platform inside the sintering furnace, the distance between the second and first positioning sleeves can be set in advance. The second positioning sleeve can serve as an external reference to determine whether the first positioning sleeve and the material box have reached the predetermined position inside the furnace. This ensures that the material box is always at the predetermined center position of the material platform inside the sintering furnace, reducing errors caused by manual judgment and improving production efficiency.

[0025] To further illustrate the technical solution of this utility model, the following description is provided in conjunction with the accompanying drawings and embodiments.

[0026] like Figures 1 to 6 As shown, this utility model provides a furnace charging car for sintering NdFeB, including a car body 1. At least two sets of horizontal guide wheels 2 are arranged rearward on the front ends of both sides of the car body 1. Guide plates 3 are arranged corresponding to the horizontal guide wheels 2. The guide plates 3 are installed on the inner side of the base of the NdFeB sintering furnace. The car body 1 can move into the space below the base of the NdFeB sintering furnace under the guidance of the guide plates 3 and the horizontal guide wheels 2.

[0027] Specifically, two omnidirectional casters with brakes are installed at the lower rear end of vehicle body 1, and rollers are installed at the bottom front end of vehicle body 1.

[0028] Preferably, the number of horizontal guide wheels 2 installed in actual use can be set according to requirements. In this embodiment, at least three sets of horizontal guide wheels 2 are provided from the front end of the vehicle body to the rear.

[0029] A mounting frame 4 is provided at the rear end of the vehicle body 1, and a lifting seat 5 is sleeved on the mounting frame 4. A jack 6 is provided on the vehicle body 1 to control the lifting seat 5 to move up and down along the mounting frame 4. Two insertion rods 7 are provided at the front of the mounting frame 4 to transport the material box containing NdFeB into the material platform inside the NdFeB sintering furnace.

[0030] Furthermore, vertical guide wheels 8 are provided on both the front and rear sides of the lifting seat 5, allowing the lifting seat 5 to move up and down along the mounting frame 4 via the vertical guide wheels 8. The vertical guide wheels 8 can roll along the mounting frame 4, improving the lifting flexibility of the lifting seat 5.

[0031] Furthermore, the top of the jack 6 is connected to the mounting shaft 9, and two sprockets 10 are installed at both ends of the mounting shaft 9. The sprockets 10 are connected to the transmission chain 11. One end of the transmission chain 11 is connected to the fixed crossbeam 101 set on the front side of the mounting frame 4 through a swivel bolt, and the other end of the transmission chain 11 is connected to the lifting seat 5 through a swivel bolt.

[0032] Specifically, a connecting plate 501 for installing live bolts is provided on the lower rear side of the lifting seat 5. At least one limiting plate 502 is provided above the connecting plate 501. The limiting plate 502 is provided with a limiting hole 503 for the transmission chain 11 to pass through. The connecting plate 501 and the limiting plate 502 are integrally provided with the lifting seat 5 or fixedly provided at the rear of the lifting seat 5.

[0033] Specifically, mounting holes are provided on the fixed crossbeam 101 and the connecting plate 501 for corresponding live bolts. One end of the transmission chain 11 is connected to the fixed crossbeam 101, and the other end passes through the limiting hole 503 and connects to the limiting plate 502. As the jack 6's push rod rises and falls, the transmission chain 11 will drive the limiting plate 502 to rise and fall, thereby driving the lifting seat 5 to rise and fall. Since the jack 6 and the lifting seat 5 are not on the same plane, the setting of the limiting plate 502 and the limiting hole 503 makes the vertical lifting force on the lifting seat 5 more uniform, making it easier for it to move up and down.

[0034] Furthermore, at least one mounting ring 12 is provided on the side of the mounting bracket 4, and an L-shaped stop bar 13 is installed inside the mounting ring 12. The L-shaped stop bar 13 has a horizontal section and a vertical section. The vertical section of the L-shaped stop bar 13 is rotatably inserted into the mounting ring 12, and the horizontal section of the L-shaped stop bar 13 can be rotated to the bottom of the lifting seat 5 to prevent the lifting seat 5 from sliding down.

[0035] Specifically, there are at least two mounting rings 12.

[0036] Specifically, at least two mounting rings are provided on both sides of the mounting frame 4, or at least two mounting rings are provided on one side. The number of mounting rings on one side can be set according to requirements, and one of the mounting rings can be set according to the inlet height of the sintering furnace. In actual production, the material is loaded by lifting the material in the glove box with the insert rod 7, so that it is above the height of the platform inside the glove box, and then the material is moved horizontally out. The material, i.e., the material box, is then transported into the sintering furnace by the car body 1. Before entering the furnace, the height of the material needs to be adjusted to correspond to the height of the sintering furnace opening, so that the material is higher than the lower edge of the sintering furnace opening and higher than the material platform inside the sintering furnace. The other mounting ring can be set according to the height of the lower edge of the sintering furnace opening, so that it is higher than the lower edge of the sintering furnace opening. After the material box is placed on the material platform inside the sintering furnace, the insert rod will not collide with the sintering furnace opening. The combination of the two can greatly reduce the time spent in the transition stage of the material box from the glove box to the sintering furnace. On the one hand, it reduces the exposure time of the material box, and on the other hand, it improves the overall production efficiency. It can also reduce the workload of workers and avoid a series of problems caused by human judgment errors.

[0037] Furthermore, a push handle is provided at the rear of the mounting bracket 4. The push handle is existing technology and is not shown in the figure. It is used to push the entire device.

[0038] Furthermore, a first positioning sleeve 14 is slidably connected to the insertion rod 7. The first positioning sleeve 14 is used to determine the loading position of the NdFeB material box on the insertion rod 7. A vertical positioning rod 23 is provided above the first positioning sleeve 14, and a first bolt 15 for fastening is provided on the side of the first positioning sleeve 14. The purpose of the first positioning sleeve 14 is to standardize the material discharge stage of the glove box, reduce the difficulty of operation for workers, and avoid the problem that the material box cannot be accurately placed in the predetermined position on the material platform inside the sintering furnace due to insufficient worker experience. Since the material box has a certain stacking height, the vertical positioning rod 23 further improves the positioning capability of the first positioning sleeve 14, and at the same time can provide rear support during transportation, improving transportation stability.

[0039] Furthermore, a second positioning sleeve 16 is slidably connected to the insertion rod 7. The second positioning sleeve 16 is located behind the first positioning sleeve 14. The second positioning sleeve 16 is used to determine the position of the NdFeB material box inside the NdFeB sintering furnace. A second bolt 17 for fastening is provided on the side of the second positioning sleeve 16. The purpose of the second positioning sleeve 16 is to assist the worker in judging the position of the material box inside the sintering furnace, saving time and improving production efficiency.

[0040] Furthermore, the top of the second positioning sleeve 16 is provided with an installation sleeve 18, on which an installation groove 1801 is constructed. The installation groove 1801 is rotatably connected to a rotating stop bar 19. After the rotating stop bar 19 is rotated to a horizontal position, it can prevent the vehicle body 1 from moving into the gap below the base of the NdFeB sintering furnace. A third bolt 20 for fastening is provided on the side of the installation sleeve 18. Due to the inertia of the vehicle body, the rotating stop bar 19 is designed to prevent the vehicle body 1 from continuing to move into the gap below the base of the NdFeB sintering furnace. During this process, it can be set so that when the rotating stop bar 19 contacts the outer edge of the sintering furnace opening, the material box is exactly at the center position of the material platform inside the sintering furnace, saving time and further reducing the error of manual judgment, thereby improving production efficiency.

[0041] Furthermore, a buffer layer is provided on the side of the rotating stop 19 that contacts the sintering furnace opening or on the entire rotating stop 19. The buffer layer can be made of sponge or rubber.

[0042] Furthermore, a mounting plate 21 is connected to the upper part of the front end of the vehicle body 1, and horizontal guide wheels 2 are mounted on the mounting plate 21. The mounting plate 21 is detachably mounted on the vehicle body 1, and multiple adjusting screw holes 103 can be provided on the vehicle body 1 so that the horizontal guide wheels 2 on both sides can be relatively close or relatively far apart, thereby adapting to sintering furnaces of different sizes and specifications, and ensuring that the horizontal guide wheels 2 can always be stably matched with the guide plate 3.

[0043] Furthermore, a horizontal slide groove 102 is provided on the vehicle body 1, and a slider 2101 is provided at the bottom of the mounting plate 21 corresponding to the horizontal slide groove 102. The slider 2101 can move inward or outward along the horizontal slide groove 102 so that the horizontal guide wheel 2 can cooperate with the guide plate 3. The slider 2101 and the vehicle body 1 are fixed together by a fourth bolt 22. Multiple adjusting screw holes 103 are provided above the slider 2101 and inside the horizontal slide groove 102 corresponding to the fourth bolt 22. The cooperation between the horizontal slide groove 102 and the slider 2101 can reduce the installation difficulty of the mounting plate 21. During installation, only the alignment of the fourth bolt 22 and the adjusting screw holes 103 in the direction of the horizontal slide groove 102 needs to be considered, saving installation time.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all changes falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model.

[0045] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
