Description

Technical Field

[0001] The invention relates to the technical field of high-temperature environment transportation equipment, and in particular to a high-temperature furnace front rotary track transportation equipment. Background Art

[0002] In the high-temperature refining industry, high-temperature liquid substances are refined in the high-temperature furnace. It is usually necessary to set up transportation equipment next to the high-temperature furnace to transport the high-temperature liquid substances in the high-temperature furnace. For example, the silicon manufacturing process involves the refining of silicon. The high-temperature silicon water obtained by refining needs to be taken out of the refining furnace and put into the silicon bag, and then the silicon bag is transported out to transport the high-temperature silicon water. At present, the commonly used transportation method in the industry is to set up tracks in front of the high-temperature furnace, and set up a rail car for loading silicon bags on the track. Usually, the rotating part of the track is surrounded in front of the high-temperature refining furnace, close to the silicon water feeding area. The rail car approaches the high-temperature furnace from one direction along the track. When the rail car runs on the rotating part of the track, the silicon water is poured from the high-temperature refining furnace into the silicon bag. Then the rail car turns around after passing the turning part and moves away from the high-temperature furnace to complete the transportation of the high-temperature silicon water. The track includes an inner rail and an outer rail. The inner rail is close to the high-temperature refining furnace. When the silicon water in the high-temperature refining furnace is poured into the silicon bag in the on-site environment, some of the high-temperature silicon water will spill onto the inner rail of the track, causing the inner rail to deform or even break. If there is a card-connected relationship between the wheel matching the inner rail on the rail car and the inner rail, such as a train wheel with a convex edge against the rail, the deformation or breakage of the inner rail will cause the wheel to be unable to pass. Summary of the invention

[0025] The following specific embodiments are only explanations of the present invention and do not limit the present invention. After reading this specification, those skilled in the art can make modifications to this embodiment without creative contributions as needed, but as long as it is within the scope of the claims of the present invention, it is protected by the Patent Law.

[0026] A high-temperature furnace-front rotary track transportation device of the present invention includes a rotary track 1 and a flatbed truck 2. The rotary track 1 includes an inner track 12 and an outer track 11. The flatbed truck 2 includes a vehicle frame 21, a heat insulation box 22 fixed above the vehicle frame 21, two front and rear driving devices 23 installed on the vehicle frame 21, and a front outer rail wheel set 31, a front inner rail wheel set 32, a rear outer rail wheel set 33, and a rear inner rail wheel set 34 installed on the vehicle frame 21 and capable of steering. The heat insulation box 22 is a closed box body, inside which a storage battery 41 and an electric control unit 42 are arranged. The heat insulation box 22 is located on one side above the vehicle frame 21. When the flatbed truck 2 carries a silicon package 8, the heat insulation box 22 is located beside the silicon package 8 instead of below it. Therefore, the high-temperature silicon water flowing out of the silicon package 8 will not flow into the heat insulation box 22, and the high-temperature silicon water leaking from the high-temperature refining furnace to the ground will not directly heat the heat insulation box 22. In addition, the heat insulation box 22 itself has the function of isolating the heat in the external environment. Therefore, the storage battery 41 and the electric control unit 42 in the heat insulation box 22 will not stop working due to overheating, ensuring that the flatbed truck 2 can move forward normally and ensuring the smooth transportation of the silicon package 8. As in the prior art, in order to prevent the deformation or fracture of the inner track 12 from affecting the movement of the flatbed truck 2, in this embodiment, the front outer rail wheel set 31 and the rear outer rail wheel set 33 both have edge portions 35 arranged on both sides of the outer track 11. The edge portions 35 can play a certain limiting and clamping role, while the front inner rail wheel set 32 and the rear inner rail wheel set only press on the inner track 12 and do not have edge portions 35, so they can move forward normally even if the inner track 12 is deformed or fractured; wherein the edge portion 35 is a protruding portion located at the outer edge of the front outer rail wheel in the front outer rail wheel set 31 and a protruding portion located at the outer edge of the rear outer rail wheel in the rear outer rail wheel set 33. The two front and rear driving devices 23 drive the front outer rail wheel set 31 and the rear inner rail wheel set 34 to move forward, or drive the front inner rail wheel set 32 and the rear outer rail wheel set 33 to move forward, or drive the front outer rail wheel set 31 and the rear outer rail wheel set 33 to move forward; in the first two cases, two diagonal wheel sets obtain driving forces, and in the latter case, two wheel sets moving on the outer track 11 obtain driving forces. In all three cases, one wheel set on the front side and one wheel set on the rear side obtain driving forces; in actual use, the output powers of the two driving devices 23 are the same, and the driving forces obtained by the wheel sets are the same. When turning, if the edge portion 35 of the front outer rail wheel has a tendency to catch on the outer track 11, the front outer rail wheel will be subject to a greater resistance, and the front side of the flatbed truck 2 tends to decelerate, but one wheel set on the rear side still obtains a driving force and pushes the flatbed truck 2 from the rear, thereby pushing the front outer rail wheel set 31 to overcome the resistance and roll over the outer track 11, avoiding the occurrence of rail jamming and ensuring the smooth movement of the flatbed truck 2. The driving device 23 includes a motor and a reducer. The output powers of the two front and rear driving devices 23 are the same, but when turning, due to the existence of factors such as resistance, the inner and outer side wheel sets travel at different speeds.Among the three implementation manners of the specific layout of the driving device 23, in the first two diagonal arrangements, the driving force obtained by the flatbed truck 2 can be relatively balanced, the derailment tendency is small during cornering, and the operation is stable; while in the third arrangement where the driving force is provided for the outer wheel sets, the derailment tendency of the flatbed truck 2 is relatively large during cornering. The edge portion 35 of the outer wheel set is closely adjacent to the outer track 11. Although it will not derail, it is not very stable. Therefore, the diagonal arrangement is preferably adopted in this embodiment. The flatbed truck 2 in this embodiment can travel forward or backward on the turning track 1, and the rail jamming phenomenon can be avoided in both cases.

[0027] For further improvement, in this embodiment, it is preferably that the distance between the two edge portions 35 of the front outer rail wheel set 31 and the rear outer rail wheel set 33 is more than twice the width of the part of the outer track 11 located between the two edge portions 35, that is, the two edge portions 35 of the front outer rail wheel set 31 and the rear outer rail wheel set 33 are not clamped on the outer track 11, but sufficient displacement space is left, so that the flatbed truck 2 can adapt to the situation where the width between the inner track 12 and the outer track 11 is not the same everywhere, ensuring that the flatbed truck 2 can travel smoothly. During specific displacement, the front inner rail wheel set 32 and the rear inner rail wheel set 34 do not have edge portions 35 and can be directly displaced on the inner track 12, while the front outer rail wheel set 31 and the rear outer rail wheel set 33 have edge portions 35. After appropriate displacement, they can abut against the outer track 11 to prevent derailment and ensure that the flatbed truck 2 can travel smoothly at the same time.

[0028] In this embodiment, it is preferably further provided with two front and rear linkage rods 24. The front linkage rod 24 is rotatably connected to the front outer rail wheel set 31 and the front inner rail wheel set 32 at both ends respectively, and the rear linkage rod 24 is rotatably connected to the rear outer rail wheel and the rear inner rail wheel at both ends respectively, ensuring that the steering angles of the front outer rail wheel set 31 and the front inner rail wheel set 32 are the same during steering, and the steering angles of the rear outer rail wheel set 33 and the rear inner rail wheel set 34 are the same, preventing a certain wheel set from getting stuck on the track, thereby ensuring the smooth travel of the flatbed truck 2. Further, it is preferably that the front outer rail wheel set 31 and the front inner rail wheel set 32 both have front swing support rods 36 and the front swing support rods 36 of the two are arranged side by side, the rear outer rail wheel set 33 and the rear inner rail wheel set 34 both have rear swing support rods 37 and the rear swing support rods 37 of the two are arranged side by side, the vehicle frame 21 includes a front intermediate support rod 211 and a rear intermediate support rod 212, and a spring 5 is connected between the front intermediate support rod 211 and the two front swing support rods 36, and a spring 5 is connected between the rear intermediate support rod 212 and the two rear swing support rods 37. The spring 5 provides a pre-tightening force for the four wheel sets. Whether traveling in a straight line or turning, the spring 5 can keep the four wheel sets stable and not shake easily, especially playing a restrictive role on the front inner rail wheel set 32 and the rear inner rail wheel set 34 to prevent them from derailing, thereby ensuring the smooth travel of the flatbed truck 2.

[0029] Since the edge portions 35 in the front outer rail wheel set 31 and the rear outer rail wheel set 33 in this embodiment do not truly engage with the outer rail 11, although derailment can be prevented, the reliability is not high. Therefore, in this embodiment, it is preferred that a guide wheel assembly 6 is provided on the front side of the front outer rail wheel set 31 and the rear side of the rear outer rail wheel set 33. The guide wheel assembly 6 includes a guide bracket 61 and two left and right guide wheels 62 arranged on both sides of the outer rail 11. The rotation axis of the guide wheel 62 is in the vertical direction and the wheel surface faces the outer rail 11. The distance between the two guide wheels 62 on both sides is more than twice the width of the part of the outer rail 11 located between the two guide wheels 62 on both sides. The guide wheel assembly 6 can contact the outer rail 11 through the guide wheels 62 on both sides, and the guide bracket 61 is fixed, restricting the distance between the two guide wheels 62. Therefore, the guide wheel assembly 6 can play a role in restricting the wheel set on the outer rail 11, further preventing derailment and ensuring the normal movement of the flatbed truck 2. Moreover, when the front outer rail wheel set 31 and the rear outer rail wheel set 33 shift on the outer rail 11 due to changes in the track width, the contact between the guide wheel 62 and the side of the outer rail 11 can facilitate the shifting of the wheel set more conveniently.

[0030] Due to the harsh environment, a lot of impurities will fall on the track, affecting the movement of the flatbed truck 2. Therefore, for further improvement, in this embodiment, it is preferred that cleaning brushes 7 are provided on the front and rear sides of the front outer rail wheel set 31, the front inner rail wheel set 32, the rear outer rail wheel set 33, and the rear inner rail wheel set 34. The cleaning brushes 7 contact the rotary track 1. During the movement, the cleaning brushes 7 will clean the track to remove impurities, and then the wheels in the wheel set will press on the track, further ensuring the smooth movement of the flatbed truck 2. The cleaning brushes 7 are preferably made of wire brushes.

[0031] In this embodiment, the heat insulation box 22 is located on one side above the vehicle frame 21. When the flatbed truck 2 loads the silicon package 8, the heat insulation box 22 is located beside the silicon package 8. Although the high-temperature silicon water flowing out of the silicon package 8 will not flow onto the heat insulation box 22, the high-temperature silicon water falling from above may still land on the top of the heat insulation box 22. Therefore, in this embodiment, it is preferred that the heat insulation box 22 includes an inclined top cover plate 221. When high-temperature silicon water lands on the top cover plate 221, it can flow down along the top cover plate 221 and leave the top cover plate 221, avoiding heating the inside of the heat insulation box 22 by the high-temperature silicon water, and preventing the battery 41 and the electrical control unit 42 in the heat insulation box 22 from stopping working due to overheating, ensuring that the flatbed truck 2 can move normally. Further, it is preferred that a cooling fan 43 is provided inside the heat insulation box 22 to cool the inside of the heat insulation box 22, avoiding too high a temperature inside the heat insulation box 22 and ensuring the normal operation of the battery 41 and the electrical control unit 42.

[0032] Furthermore, in this embodiment, it is preferred that refractory bricks are laid on the vehicle frame 21, and the refractory bricks form the platform 25 of the flatbed vehicle 2. During actual use, the silicon package 8 is placed on the platform 25 formed by the refractory bricks, reducing the damage caused to the flatbed vehicle 2 by the high-temperature silicon water falling on the platform 25 and protecting the remaining components inside the vehicle frame 21. Specifically, the vehicle frame 21 has a hem that surrounds the platform 25, enabling the refractory bricks to form a tight and flat platform 25, improving the load-bearing effect and heat insulation effect. A layer of asbestos can also be pre-laid under the refractory bricks to further improve the heat insulation performance. Although the battery 41 and the electric control unit 42 are protected inside the heat insulation box 22, the two driving devices 23 are on the vehicle frame 21 and below the platform 25. The high-temperature silicon water flowing onto the ground is very close to the driving devices 23, and the temperature of the heat radiated upward by this high-temperature silicon water is extremely high, which can cause the driving devices 23 to overheat and affect their normal operation. Therefore, in this embodiment, it is preferred that a heat insulation cover 26 is provided below the vehicle frame 21. The heat insulation cover 26 shields the driving devices 23 from below, reducing the heat transfer between the high-temperature silicon water on the ground and the driving devices 23, preventing the driving devices 23 from overheating, and also having a certain insulating effect on the external high-temperature environment, further avoiding the overheating of the driving devices 23, thus ensuring the smooth progress of the flatbed vehicle 2. Specifically, the heat insulation cover 26 includes an asbestos layer to improve the heat insulation effect. The flatbed vehicle 2 of this embodiment can adapt to harsh high-temperature environments and travel on non-standard and deformed tracks. Mainly, improvements are made to the flatbed vehicle 2 itself. On the other hand, it is also preferred that a reinforcing rod is horizontally installed between the inner track 12 and the outer track 11, specifically made of round steel, reducing the deformation degree of the tracks in high-temperature environments and when high-temperature silicon water spills, further ensuring the smooth progress of the flatbed vehicle 2.

[0033] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of various equivalent modifications or substitutions, and these modifications or substitutions should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
