[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Embodiment: As Figures 1 - 3 shown, a lifting system for a charging material pipe on a furnace wall includes a turntable 1. A rail disc 2 is fixedly connected to the turntable 1. A machine shell 3, a toothed piece 4, and a fixed material pipe rail groove 5 are fixedly connected to the rail disc 2. In this embodiment, the turntable 1 is circular and is driven to rotate by the driving device of the whole machine. The rail disc 2 is located above the turntable 1 and is integrally circular and hollow. The lower part of the rail disc 2 is fixedly connected to the turntable 1, and the upper part is fixedly connected to the machine shell 3, the toothed piece 4, and the fixed material pipe rail groove 5. In this embodiment, the toothed piece 4 and the fixed material pipe rail groove 5 form a complete circle. A material pipe rail support 6 and a winder 7 are also connected to the rail disc 2. The material pipe rail support 6 is located below the winder 7 and is fixedly connected to the rail disc 2. The winder 7 is slidably connected to the rail disc 2 through a track. A motor 8 is installed on the winder 7. The output end of the motor 8 is connected to a motor gear 9. The motor gear 9 meshes with the toothed piece 4. When the motor 8 is started, the motor gear 9 rotates along the toothed piece 4 and drives the winder 7 to slide along the track. A sliding material pipe rail groove 10 is fixedly connected to the winder 7. One end of the sliding material pipe rail groove 10 close to the fixed material pipe rail groove 5 is flush with the fixed material pipe rail groove 5, and the other end gradually slopes downward.

[0034] A hopper 28 and a screw conveyor 29 are arranged in the machine shell 3 for spreading materials. The screw conveyor 29 is connected to a material pipe 30. A shaftless screw is installed inside the material pipe 30 to make the material spreading uniform and stable. The shaftless screw has a large elasticity. Affected by it, the material pipe is not easy to bend, and the bending degree has a certain limit. Therefore, the fixed material pipe rail groove 5 mainly guides the material pipe led out from the screw conveyor according to a certain bending degree; the winder 7 mainly winds the material pipe around the equipment with force to play the role of lifting the material pipe orifice; the material pipe rail support 6 mainly plays the role of supporting and guiding the material pipe. The part of the material pipe leaving the fixed material pipe rail groove 5 is in a suspended state and will show the phenomena of sagging and natural straightening. The material pipe rail support 6 restricts these phenomena and enables the material pipe to run according to the set bending degree and track.

[0035] As Figures 2 - 3As shown, the winder 7 is located above the tooth segment 4. The motor 8 is fixedly installed on the winder 7. The motor 8 shaft is vertically downward and passes through the winder 7. The motor gear 9 is installed below and meshes with the tooth segment 4. Inside the winder 7, that is, on the side close to the rail disc 2, a set of vertical rail wheels 11, a set of sliding balls 12, and a set of horizontal rail wheels 13 are also installed. Under the common constraint of the vertical rail wheels 11 and the sliding balls 12 on the rail disc 2 along the surface of the tooth segment 4, a lever-like stable form is formed to play a positioning role in the vertical direction; the horizontal rail wheels 13 are attached to the inner side of the tooth segment 4, and the motor gear 9 meshes with the outer side of the tooth segment 4, thus forming a positioning in the horizontal direction. The sliding material pipe rail groove 10 is located outside the winder 7. The bottom and the outside of the sliding material pipe rail groove 10 are equipped with rolling shafts 14 to enable the material pipe to slide without resistance.

[0036] As Figure 1 shown, a plurality of material pipe rail supports 6 are provided, and the material pipe rail supports 6 are only provided below the tooth segment 4. Since the winder 7 can only move along the tooth segment 4, it also drives the material pipe to be retracted or released only within the range of the tooth segment 4.

[0037] As Figure 4 shown, the material pipe rail support 6 includes a rail support base 15, a rail support bracket 16, and a rocker 17. The rail support base 15 is fixed on the rail disc 2. The rail support bracket 16 is in a horizontal position to restrict the material pipe in the vertical direction, and the rocker 17 is in a vertical position to restrict the material pipe in the horizontal direction. The inner end of the rail support bracket 16, that is, the end close to the rail disc 2, is hinged to the rail support base 15, and the outer end is hinged to the rocker 17. One end of the rocker 17 is fixedly connected with a rocker gear 18, and the axial extension of the rocker gear 18 is hinged to the rail support bracket 16.

[0038] A sector gear 19 is fixedly connected to the upper part of the rail support seat 15, and a limit plate 20 is fixedly connected to the lower part. The sector gear 19 and the limit plate 20 are hinged to the end of the rail support 16 through a pin shaft in the middle. An intermediate gear 21 meshing with the sector gear 19 and a rack 22 meshing with the intermediate gear 21 are installed on the rail support 16. The rack 22 is arranged in the direction from the rail support seat 15 to the rocker 17. There are two sets of teeth on the rack 22, which are located on two faces respectively, that is, the two sets of teeth are arranged at 90° to each other. The two sets of teeth are located at both ends of the rack 22 respectively. The intermediate gear 21 meshes with one end of the rack 22, and the other end of the rack 22 meshes with the rocker gear 18. The intermediate gear 21 and the rocker gear 18 are at 90° axially, and the transmission is realized by the teeth on the two 90° faces of the rack 22. The rocker gear 18 and the rocker 17 are fixedly installed together and are hinged to the outer end of the rail support 16. The axial direction of the rocker gear 18 extends out and a rocker spring 23 is installed. The rocker spring 23 is coaxially assembled with the rocker 17 to limit the free movement of the rocker 17. Two limit grooves 24 are arranged on the limit plate 20, and a positioning bead 25 is fixedly connected to the rail support 16. The two limit grooves 24 are arranged along the movement direction of the rail support 16. Initially, the positioning bead 25 is located in one of the limit grooves 24. When the rail support 16 moves, the positioning bead 25 moves to the other limit groove 24 accordingly. After the movement of the rail support 16 is completed, the positioning bead 25 is located in the other limit groove 24 to limit the rail support 16.

[0039] In this way, when the rail support 16 rotates along the pin shaft, the intermediate gear 21 rotates under the action of the sector gear 19, drives the rack 22 to move at the same time, the rack 22 drives the rocker gear 18 to rotate, and the rocker gear 18 drives the rocker 17 to rotate, so that the rocker 17 is in the horizontal or vertical position.

[0040] As Figure 5 shown, when the winder 7 rotates clockwise, the outlet of the material pipe will be lifted. At the same time, the distance between the sliding material pipe rail groove 10 and the fixed material pipe rail groove 5 becomes larger and larger, and the conveying pipe will be suspended and sag. At this time, the pipe rail support 6 will rotate out and hold up the material pipe; when the pipe rail support 6 rotates outwards and turns to a certain angle, the rocker 17 rises to restrain the elastic outward extension of the material pipe. When the winder 7 rotates counterclockwise, the rail support will extend the rocker 17 and return to the original position in the reverse order. In this embodiment, a total of five groups of pipe rail supports 6 are installed on the equipment, and other quantities can also be installed according to the actual situation.

[0041] As Figure 6 shown, the limit plate 20 on the pipe rail support 6 is located at the lower part and is locked in position through a pin shaft and a flat key and cannot rotate. There are two limit grooves 24 on the limit plate 20. In this embodiment, they are groove A and groove B respectively. A positioning bead 25 is installed on the rail support 16. When the positioning bead 25 is in groove A, it is in the reset state (as Figure 7 ), and when it is in groove B, it is in the working state (as Figure 8 ).

[0042] As Figure 7 and Figure 9 shown, a toggle shaft 26 is arranged below the winder 7, and a guide groove 27 is arranged on the rail bracket 16. The guide groove 27 is of a special shape, is arranged facing the toggle shaft 26 above, and has openings at both ends. The toggle shaft 26 can slide along the guide groove 27. As Figure 10 shown, the winder 7 rotates clockwise. When the toggle shaft 26 reaches the rail bracket 16, it enters the guide groove 27. As Figure 11 shown, the toggle shaft 26 pushes the rail bracket 16 to rotate clockwise from the reset state. When it rotates 70°, the rocker 17 on the rail bracket 16 has rotated out of the discharge pipe part, and the rocker 17 has tilted and is no longer affected by the discharge pipe. At this time, the intermediate gear 21 on the rail bracket 16 meshes with the sector tooth piece 19 on the rail support seat 15, as Figure 12 shown. The rail bracket 16 continues to rotate 15°, as Figure 13 shown. The pitch arc length of the sector tooth piece 19 is 15.71 mm, and the pitch arc length corresponding to the 90° central angle of the intermediate gear is also 15.71 mm. Then, the intermediate gear 21 is driven to rotate 90°. As Figure 14 shown, the pitch circles of the intermediate gear 21 and the rocker gear 18 are equal. The rocker gear 18 is also driven to rotate 90° under the drive of the rack 22. The rocker gear 18 is fixedly installed with the rocker 17, and the rocker 17 also rotates 90°, rotating from the horizontal direction to the vertical direction. As Figure 15 shown, at this time, the positioning detent 25 is in the B groove position. The toggle shaft 26 on the winder 7 rotates out of the guide groove 27, and the rail bracket 16 stops rotating. At this time, the rail bracket 16 is in a horizontal state and holds up the discharge pipe, and the rocker 17 is in a vertical state to limit the outward expansion of the discharge pipe, realizing the limit of the discharge pipe.

[0043] In this embodiment, when the winder 7 moves clockwise, it drives the discharge pipe to wind around the periphery of the equipment, causing the lower discharge port of the discharge pipe to rise accordingly until the winder 7 rotates from one end of the tooth piece 4 to the other end, the winding of the discharge pipe is completed, and the lower discharge port also rises to the highest point. At this time, the feeding is also completed. When disassembling the equipment, there is no need to perform additional disassembly and fixation on the discharge pipe. When feeding the furnace, the equipment is fixed at the furnace opening, and the motor 8 is started to reverse, driving the winder 7 to rotate back from the end of the tooth piece 4. The discharge pipe is slowly lowered through the sliding discharge pipe rail groove 10, and the lower discharge port gradually drops to the lowest point. During the movement process, the movement of the corresponding discharge pipe rail support 6 is opposite to that during the rise: the toggle shaft 26 on the winder 7 enters the guide groove 27 from the other end of the guide groove 27, pushes the rail bracket 16 to rotate, and at the same time, the positioning detent 25 disengages from the B groove and moves towards the A groove. The intermediate gear 21 rotates in reverse, drives the rocker 17 to rotate towards the horizontal position through the rack 22 until the toggle shaft 26 rotates out of the guide groove 27, and the positioning detent 25 returns to the A groove for positioning. The entire discharge pipe rail support 6 returns to as Figure 7The state when it is retracted as shown until all the pipe rail supports 6 are retracted and the pipe lowering is completed.
