Description

Technical Field

[0001] The utility model belongs to the field of material transportation of iron-making blast furnaces, and more specifically, relates to a self-balancing blast furnace charge car. The utility model also relates to a blast furnace material transportation system. Background Art

[0002] The charge car winch pulls two loading cars, each traveling on the ironmaking facility's inclined bridge track. The two cars move in opposite directions, with the loaded charge car ascending and the empty one descending. To enable automatic unloading when the ascending charge car reaches the top of the inclined bridge, the charge car track at the top of the bridge is designed as a curved track, known as the main curved track. An auxiliary curved track, wider in gauge than the main curved track, is installed outside the main curved track to enable the charge car to tip over. As the front wheels of the charge car advance along the main curved track, the rear wheels transition onto the auxiliary curved track and continue ascending, gradually lifting the rear of the charge car. When the front wheels reach the end of the main curved track, the charge car tips over, automatically unloading the charge into the receiving hopper on the furnace roof.

[0003] When the winch reverses, the empty car that has unloaded the materials will automatically move down from the auxiliary curved track due to its own weight, and at the same time, another car loaded with materials will move up along the track on the other side of the inclined bridge. The loading operation is repeated in this way.

[0004] However, with the continuous expansion of blast furnaces, the corresponding volume of the charge car is also constantly increasing. The fully loaded charge car is very heavy, and the rear wheels need to be on the auxiliary track when the charge car reaches the furnace top to unload. The charge car runs on the inclined bridge track for a long time, and there are inevitable differences in the planes of the main and auxiliary tracks. The maintenance cycle is long and not easy to find. The front and rear wheels of the existing charge car are all fixedly connected to the car body, which may cause bumps when the rear wheels are on the auxiliary track. There are safety hazards and it is urgent to improve. Utility Model Content

[0034] Compared with the prior art, the self-balancing blast furnace charge car in the present invention can carry the car body 1 during operation through the mutual cooperation of the carrying wheels and the axle in the carrying mechanism 2, so as to facilitate the movement of the car body 1 along the predetermined track. During the intersection of the main and secondary tracks, the present invention can reduce the shaking of the car body 1 by the swing of the second axle 24, and solve the technical problem that the existing main and secondary tracks cause the car body 1 to be unbalanced due to the docking error. In addition, during the movement of the car body 1, the present invention can also tow the car body 1 through the traction beam 31 and the traction head 32, so that the middle part of the car body 1 is connected to the traction beam 31, which is beneficial to the overall force balance of the car body 1 during the movement, and prevents the car body 1 from tipping over during the pulling process.

[0035] Based on the above embodiment, a feasible implementation method is proposed. The supporting mechanism 2 also includes a first connecting component 26, which includes a fixing frame 261, a fixing plate 262 and a locking bolt 263. The fixing frame 261 is provided at the bottom of the vehicle body 1. The fixing frame 261 is "U"-shaped and has an opening facing downward. The fixing plate 262 is connected to the opening of the fixing frame 261 by the locking bolt 263. The first wheel axle 23 is installed in the fixing frame 261 through the fixing plate 262, so that the first wheel axle 23 is clamped by the fixing frame 261 and the fixing plate 262, making the connection between the first wheel axle 23 and the vehicle body 1 more secure. Similar to the above embodiment, corresponding to the second wheel axle 24, a structure similar to the fixing frame 261 described above is also provided at the bottom of the vehicle body 1, but the opening of this fixing frame 261 is not provided with any other sealing structure, so that the second wheel axle 24 can swing around the first hinge axis 25 and prevent the second wheel axle 24 from deviating from the verticality of the first hinge axis 25.

[0036] In one feasible embodiment, the support mechanism 2 further includes two first support columns 27 and two second support columns 28. The two first support columns 27 are respectively located on either side of the front width of the vehicle body 1. The first support columns 27 extend in the vertical direction, and the bottom ends of the first support columns 27 are connected to the first wheel axle 23. The two second support columns 28 are respectively located on either side of the rear width of the vehicle body 1. The second support columns 28 extend in the vertical direction, and the bottom ends of the second support columns 28 are provided with escape grooves extending in the vertical direction, so that the second wheel axle 24 can swing up and down in the escape grooves. With this arrangement, this embodiment can enhance the structural strength of the vehicle body 1 through the two support columns, and ensure the load-bearing capacity of the front and rear load-bearing wheels 21 and 22 on the vehicle body 1 through the connection between the two wheel axles and the two support columns.

[0037] In a feasible embodiment, a second hinge shaft 29 hinged to the second support column 28 is provided at one end of the traction beam 31 away from the traction head 32. The second hinge shaft 29 is provided directly above the second wheel axle 24, and the axis of the second hinge shaft 29 is parallel to the second wheel axle 24, so that the car body 1 can be flipped by pulling the traction beam 31, thereby facilitating the delivery of materials in the car body 1 into the blast furnace. The second hinge shaft 29 provided directly above the second wheel axle 24 makes the force application point of the traction beam 31 on the car body 1 located in the middle and rear of the car body 1, making the force application point of the traction beam 31 on the car body 1 more reasonable.

[0038] Preferably, in a feasible embodiment, there are two traction beams 31, and the two traction beams 31 are arranged side by side along the width direction of the vehicle body 1, and the two traction beams 31 are respectively provided on both sides of the vehicle body 1, so that the pulling force of the traction beam 31 on the vehicle body 1 is more evenly distributed, thereby preventing the vehicle body 1 from being offset during the pulling process.

[0039] Based on the above embodiment, a feasible implementation method is proposed. Specifically, the traction mechanism 3 also includes a triangular plate 33, a mounting beam 34 and a connecting beam 35. The two ends of the mounting beam 34 are respectively connected to the ends of the two traction beams 31 away from the second hinge shaft 29. The number of the triangular plates 33 is two, and the triangular plate 33 is a right-angled triangle. The three corners of the triangular plate 33 are respectively provided with a first connecting hole 331, a second connecting hole 332 and a third connecting hole 333. The first connecting hole 331 corresponds to the right angle of the triangular plate 33, and the second connecting hole 332 corresponds to the right angle of the triangular plate 33. The third connecting hole 333 corresponds to one of the acute angles of the triangle plate 33, and the third connecting hole 333 corresponds to the other acute angle of the triangle plate 33. The two triangle plates 33 are symmetrically distributed on the mounting crossbeam 34, and the two second connecting holes 332 on the two triangle plates 33 are arranged correspondingly. The triangle plate 33 is connected to the mounting crossbeam 34 through the first connecting hole 331 and the second connecting hole 332. The third connecting hole 333 is located at the end of the triangle plate 33 away from the mounting crossbeam 34. The two ends of the connecting beam 35 are respectively connected to the two third connecting holes 333. The traction head 32 is connected to the two correspondingly distributed first connecting holes 331. With such a configuration, this embodiment can form a connection between the traction head 32 and the mounting crossbeam 34 through the mutual adaptation of the triangle plate 33 and the connecting beam 35, so that the pulling force of the traction head 32 can be evenly distributed on the front end of the vehicle body 1, preventing the pulling force of the traction head 32 on the mounting crossbeam 34 from being concentrated at one point, and making the connection between the traction head 32 and the mounting crossbeam 34 more reasonable.

[0040] A feasible implementation method is proposed, in which a pendulum needle 11 is provided on one side of the vehicle body 1, and the swing axis of the pendulum needle 11 is parallel to the second hinge axis 29. A plurality of scale protrusions 12 are also formed on the vehicle body 1, and the scale protrusions 12 are evenly arranged along the swing arc of the pendulum needle 11. When the vehicle moves along the inclined track, under the action of gravity, the pendulum needle 11 is always perpendicular to the horizontal variable, and the rising angle of the vehicle can be judged by the relative position between the scale protrusion 12 on the vehicle body 1 and the pendulum needle 11.

[0041] Based on the above embodiments, a feasible implementation method is proposed. Specifically, reinforcing beams 13 are respectively provided on both sides of the vehicle body 1. The reinforcing beams 13 are used to install the second hinge shaft 29, and the reinforcing beams 13 extend along the traveling direction of the vehicle body 1 so that the reinforcing beams 13 can work together with the two support columns mentioned above to further enhance the overall structural strength of the vehicle body 1.

[0042] Based on the same inventive concept, the present invention also proposes a blast furnace material transportation system, which includes the self-balancing blast furnace charge car mentioned above.

[0043] Compared with the prior art, the blast furnace material transportation system in the present invention has all the advantages of the above-mentioned self-balancing blast furnace charge car, which will not be repeated here.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
