Description

Technical Field

[0001] The utility model relates to the technical field of charging equipment for smelting furnaces, and particularly relates to a charging equipment for steel smelting furnaces. Background Art

[0002] A smelting furnace is an important piece of equipment in industry for refining and processing metals. It extracts metal elements from ores or other raw materials through a high-temperature environment while removing impurities to obtain metals with higher purity. The ores or other raw materials for smelting are quantitatively added into the smelting furnace through a feeding device.

[0003] Some feeding hoppers adopt a mode of lifting along a track and are combined with an external raw material grab bucket. Through operating a mechanical or automatic control system, the raw materials are accurately fed into the furnace. After the feeding hopper of the smelting furnace is filled with raw materials, it will be lifted to the position of the feeding port of the smelting furnace by a tractor. When the tractor pulls the feeding hopper to move upward along the track, since the performance stability of the tractor directly affects the lifting process of the feeding hopper, if the tractor malfunctions, such as insufficient traction force or brake failure, it may cause the feeding hopper to fall out of control on the track. If the feeding hopper suddenly falls during the lifting process, it may cause the raw materials to spill, resulting in waste of resources and environmental pollution. At the same time, the falling feeding hopper may damage the track and the smelting furnace equipment, increasing the maintenance cost and the risk of production interruption. In addition, if the operator fails to avoid in time, it may also cause casualties. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a charging equipment for steel smelting furnaces, which can effectively solve the problems in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A charging equipment for steel smelting furnaces includes a track frame and a feeding hopper. One end of the track frame is fixedly installed with a tractor, and the tractor is electrically connected to an external controller through a connecting wire. Two tracks are fixedly installed on the track frame. A toothed plate and a pressure rod are respectively fixedly installed at both ends of the track. A platform frame is movably installed at the lower end of the feeding hopper. A hydraulic pump box is fixedly installed on one side of the platform frame. The bottom of the platform frame and the feeding hopper are movably connected through two hydraulic cylinders, and the hydraulic pump box and the two hydraulic cylinders are connected through hydraulic pipes. Four wheel frames are fixedly installed at the lower end of the platform frame. Two rollers are movably installed on both sides inside each wheel frame, that is, the wheel frame is movably installed on the corresponding track through the rollers inside. A pawl is movably installed at the top inside the wheel frame, and a fixed rod is also fixedly installed at the top inside the wheel frame on one side of the pawl.

[0007] As a further optimization solution of the utility model, a rack is fixedly installed at the middle position of the upper end of the track. By arranging the rack on the track, the one-way limit of the wheel frame can be realized in cooperation with the ratchet pawl.

[0008] As a further optimization solution of the utility model, a first fixed seat is fixedly installed at the lower end of the toothed plate, and a second fixed seat is fixedly installed at the lower end of the pressing rod. The toothed plate is fixedly installed at one end of the track through the first fixed seat, and the pressing rod is fixedly installed at the other end of the track through the second fixed seat.

[0009] As a further optimization solution of the utility model, a mounting seat is fixedly installed at the inner top of the wheel frame, and a fixed shaft is fixedly installed on one side of the mounting seat. Through the arrangement of the mounting seat and the fixed shaft, the ratchet pawl can be movably installed in the wheel frame and placed above the track.

[0010] As a further optimization solution of the utility model, one end of the ratchet pawl is rotatably installed on the fixed shaft, and a plurality of tooth grooves are also formed on the outer side of the ratchet pawl. The end of the ratchet pawl far from the tooth grooves freely hangs down and is clamped on the rack.

[0011] As a further optimization solution of the utility model, a clamping groove is formed at the lower end of the fixed rod, rubber pads are attached to both sides inside the clamping groove, and a slot is formed at the top inside the clamping groove. By means of the arrangement of the toothed plate, the ratchet pawl can be clamped into the clamping groove after the feeding hopper moves to one end of the track frame, so as not to affect the normal downward movement of the feeding hopper and the platform frame. By means of the arrangement of the pressing rod, the ratchet pawl can be automatically disengaged from the clamping groove, so as to realize the limit during the subsequent upward movement of the feeding hopper and the platform frame.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] For the feeding equipment for the steel smelting furnace of the utility model, a movable ratchet pawl is arranged at the inner top of the wheel frame and cooperates with the rack on the track. When the feeding hopper is loaded with raw materials and moves upward to the feeding port position of the smelting furnace, the anti-drop operation of the platform frame can be carried out. By cooperating with the toothed plate and the pressing rod at both ends of the track and the fixed rod at the inner top of the wheel frame, the ratchet pawl can be automatically clamped and limited and the limit can be released, so that the platform frame is limited by the ratchet pawl during upward movement, and the ratchet pawl does not limit the platform frame during downward movement.

Specific embodiments

[0020] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1 - 5 shown, a feeding device for a steel smelting furnace provided by the present utility model includes a track frame 1 and a feeding hopper 2. One end of the track frame 1 is fixedly installed with a tractor 3, and the tractor 3 is electrically connected to an external controller through a connecting wire. Two tracks 4 are fixedly installed on the track frame 1. A toothed plate 10 and a pressure bar 11 are fixedly installed at both ends of the track 4 respectively. The lower end of the feeding hopper 2 is movably installed with a bench 22. One side of the bench 22 is fixedly installed with a hydraulic pump box 5. The inner bottom of the bench 22 and the feeding hopper 2 are movably connected through two hydraulic cylinders 6, and the hydraulic pump box 5 and the two hydraulic cylinders 6 are connected through hydraulic pipes. Four wheel frames 7 are fixedly installed at the lower end of the bench 22. Two rollers 8 are movably installed on both sides inside each wheel frame 7, that is, the wheel frame 7 is movably installed on the corresponding track 4 through the rollers 8 inside. A ratchet pawl 9 is movably installed at the top inside the wheel frame 7, and a fixing rod 16 is also fixedly installed at the top inside the wheel frame 7 on one side of the ratchet pawl 9.

[0022] As Figures 2 - 3 shown, a rack 12 is fixedly installed at the middle position of the upper end of the track 4. By providing the rack 12 on the track 4, the ratchet pawl 9 can be used to implement one-way limit on the wheel frame 7;

[0023] As Figures 2 - 3 shown, a first fixing seat 13 is fixedly installed at the lower end of the toothed plate 10, and a second fixing seat 14 is fixedly installed at the lower end of the pressure bar 11. The toothed plate 10 is fixedly installed at one end of the track 4 through the first fixing seat 13, and the pressure bar 11 is fixedly installed at the other end of the track 4 through the second fixing seat 14;

[0024] As Figures 2 - 5As shown in the figure, a mounting seat 19 is fixedly installed at the inner top of the wheel frame 7. A fixed shaft 20 is fixedly installed on one side of the mounting seat 19. Through the arrangement of the mounting seat 19 and the fixed shaft 20, the pawl 9 can be movably installed in the wheel frame 7 and placed above the track 4. One end of the pawl 9 is rotatably installed on the fixed shaft 20. A plurality of tooth grooves 21 are also formed on the outer side of the pawl 9. The end of the pawl 9 away from the tooth grooves 21 freely hangs down and is engaged with the rack 12. A card slot 17 is formed at the lower end of the fixed rod 16. Rubber pads are attached to both sides inside the card slot 17. A slot 18 is formed at the top inside the card slot 17. With the arrangement of the toothed plate 10, the pawl 9 can be engaged into the card slot 17 after the hopper 2 moves to one end of the track frame 1, so as not to affect the normal downward movement of the hopper 2 and the bench 22. With the arrangement of the pressure rod 11, the pawl 9 can be automatically disengaged from the card slot 17, so as to realize the limit during the subsequent upward movement of the hopper 2 and the bench 22.

[0025] It should be noted that the present utility model is a feeding device for a steel smelting furnace. When the tractor 3 pulls the bench 22 to move obliquely upward on the track frame 1, the track frame 1 drives the four wheel frames 7 at the lower end to roll on the corresponding tracks 4 through the internal rollers 8 respectively. Then, the pawls 9 at the inner tops of two of the wheel frames 7 are successively engaged between two corresponding teeth on the rack 12 due to gravity as the wheel frames 7 move, so as to play a role in preventing the track frame 1 from falling rapidly. When the tractor 3 pulls the bench 22 to the upper end of the track frame 1, the wheel frame 7 drives one end of the pawl 9 to move to the toothed plate 10 synchronously through the mounting seat 19 and the fixed shaft 20, so that the tooth groove 21 position at one end of the pawl 9 is meshed and connected with the toothed plate 10, and then the pawl 9 rotates on the fixed shaft 20, and the other end of the pawl 9 is engaged into the card slot 17, thus completing the purpose of disengaging and fixing one end of the pawl 9 from the rack 12. After the hopper 2 finishes discharging by flipping through the hydraulic cylinder 6, the tractor 3 gradually lowers the track frame 1. At this time, since one end of the pawl 9 is disengaged from the rack 12, it will not affect the reset of the bench 22;

[0026] When the bench 22 moves to the other end of the track frame 1 and resets, the wheel frame 7 drives the slot 18 in the fixed rod 16 to insert into one end of the pressure rod 11, and then the pressure rod 11 enters the slot 18 and squeezes one end of the pawl 9 out of the card slot 17, so that one end of the pawl 9 falls back into the rack 12 again, providing conditions for the subsequent upward limit of the track frame 1.

[0027] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
