Description

Technical Field

[0001] This utility model belongs to the field of blast furnace moving technology, specifically relating to a blast furnace overall moving and rolling device. Background Technology

[0002] Blast furnace relocation is an advanced relocation technology used in ironmaking plants during blast furnace overhauls. This technology can shorten the overhaul period and the quality is significantly better than conventional overhaul methods, bringing huge benefits to ironmaking plants.

[0003] The method of installing roller trolleys at the bottom of the furnace during the pushing process enables rolling friction throughout the blast furnace pushing process, which is more reliable than sliding friction and can avoid jamming. Moreover, compared with sliding friction, the hydraulic cylinder generates less force on the furnace body during the pushing process, which can effectively protect the blast furnace body.

[0004] When the existing roller trolley is installed on the slide rail, the rollers of the roller trolley need to be precisely adjusted to be parallel to the slide rail. However, the roller trolley lacks a reference positioning mechanism, which makes it easy for errors to occur during installation. When moving over long distances, the accumulated errors may cause the roller trolley to derail or the furnace body to shift. In addition, when the existing roller trolley is used to support a large blast furnace, more roller trolleys need to be set up to ensure stable movement, which is costly. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an integral pushing and rolling device for blast furnaces.

[0006] The technical solution adopted to solve the above technical problems is: a blast furnace integral pushing and rolling device, including a support structure, on which two slide rails are installed side by side, and the top of the two slide rails roll and slide in contact with the main body of the roller trolley; The main body of the roller carriage includes a carriage frame. The carriage frame has movable grooves inside that correspond to the positions of two slide rails. Core disks are welded and fixed to the inner walls of both sides of the two movable grooves. Several rollers are arranged around the side walls of the core disks. The rollers are connected to each other by roller chains on both sides. The front and rear sides of the carriage frame are provided with auxiliary components to help calibrate the main body of the roller carriage to be parallel to the slide rails.

[0007] Furthermore, the auxiliary component includes L-shaped connecting plates welded and fixed to the front and rear side walls of the vehicle body bracket. The lower surface of each L-shaped connecting plate is fixed with symmetrically arranged rotating shafts, and the outer side walls of each rotating shaft are rotatably connected with auxiliary calibration guide wheels.

[0008] With the above technical solution, when installing the main body of the roller trolley on the slide rail, first place one end of the main body of the roller trolley on the slide rail at an angle, and then calibrate it by locking the guide wheels on the outside of the two slide rails. After calibration, place the main body of the roller trolley flat on the slide rail, which can ensure that the main body of the roller trolley is parallel to the slide rail, reduce errors, and after long-term operation, observe the gap between the guide wheels and the slide rail to determine whether the main body of the roller trolley is deviating on the slide rail. Manual adjustment can be made in time to avoid the cumulative error during long-distance movement, which may cause the roller trolley to derail or the furnace body to shift, thus improving the stability of the movement.

[0009] Furthermore, connecting lugs are welded and fixed to the left and right rear side walls of the vehicle body bracket.

[0010] The above technical solution facilitates the installation of connecting hydraulic cylinders and other traction devices, enabling automated pushing.

[0011] Furthermore, the upper surface of the vehicle body bracket is symmetrically provided with several mounting holes.

[0012] The above technical solution provides the conditions for installing the blast furnace base and facilitates disassembly and assembly.

[0013] Furthermore, the guide wheels on both sides are located on the left and right sides of the two slide rails respectively, and the guide wheels are all located above the slide rails. The distance between the adjacent rolling surfaces of the guide wheels on both sides is equal to the distance between the two slide rails on their outer side walls.

[0014] Through the above technical solution, the distance between adjacent rolling surfaces of the guide wheel is equal to the distance between the outer walls of the slide rail, forming precise guidance. This ensures that the main body of the roller carriage is parallel to the slide rail during calibration, reducing calibration errors. The guide wheel and the slide rail do not contact each other, avoiding collision and wear during pushing, and improving the service life of the components.

[0015] Furthermore, the rolling surfaces of the lower rollers are all located below the vehicle body bracket, and adjacent rollers roll into contact with each other.

[0016] Through the above technical solution, adjacent rollers contact each other to form a continuous support chain, reducing vibration and noise, while automatically adapting to minor deformations of the slide rail.

[0017] The beneficial effects of this utility model are as follows: (1) By setting up a car body bracket, core plate, roller, roller chain, movable groove and slide rail, the line contact method between the roller and the slide rail replaces the traditional sliding friction, which significantly reduces friction, reduces energy consumption and extends the service life of the slide rail and roller. The rollers are connected into a whole by the roller chain, which evenly distributes the load, avoids excessive local pressure, and improves the load-bearing stability of the device. The car body bracket is equipped with two roller structures, which, together with the two slide rails, increase the load-bearing weight of a single roller trolley, making it suitable for large furnace transfer and reducing equipment costs. (2) By setting up L-shaped connecting plates, rotating shafts, and guide wheels, the guide wheels on both sides are clamped on the outside of the two slide rails for parallel calibration, ensuring that the main body of the roller trolley is parallel to the slide rail, reducing errors. After long-term operation, the gap between the guide wheels and the slide rail can be observed to determine whether the main body of the roller trolley is deviating on the slide rail. Manual adjustments can be made in time to avoid the cumulative error during long-distance pushing, which could cause the roller trolley to derail or the furnace body to shift, thus improving the stability of pushing.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0021] like Figures 1-4 As shown, the blast furnace integral pushing and rolling device of this embodiment includes a support structure 1, on which two slide rails 2 are installed side by side, and the top of the two slide rails 2 rolls and contacts the main body 3 of the roller trolley. The main body 3 of the roller trolley includes a trolley support 301. The interior of the trolley support 301 has movable grooves 3012 corresponding to the positions of the two slide rails 2. The inner walls of the two movable grooves 3012 are welded and fixed with core disks 306. The side walls of the core disks 306 are arranged with a number of rollers 307. The rollers 307 are connected to each other by roller chains 308 on both sides. The line contact between the rollers 307 and the slide rails 2 replaces the traditional sliding friction, which significantly reduces friction, reduces energy consumption and extends the service life of the slide rails 2 and the rollers 307. The rollers 307 are connected into a whole by the roller chains 308, which evenly distributes the load, avoids excessive local pressure, and improves the load-bearing stability of the device. The front and rear sides of the trolley support 301 are provided with auxiliary components to help calibrate the parallelism between the main body 3 of the roller trolley and the slide rails 2. Each roller trolley has two roller structures, which, together with the two slide rails 2, increase the load-bearing weight of a single roller trolley, making it suitable for the transfer of large furnace bodies and reducing equipment costs. Connecting lugs 305 are welded and fixed to the left and right rear side walls of the vehicle body support 301. The connecting lugs 305 facilitate the installation of traction devices such as hydraulic cylinders to achieve automated pushing. The upper surface of the car body support 301 is symmetrically provided with several mounting holes 3011, which provide conditions for installing the blast furnace base and facilitate disassembly and assembly. The two guide wheels 304 are located on the left and right sides of the two slide rails 2 respectively. The guide wheels 304 are both located above the slide rails 2. The distance between the adjacent rolling surfaces of the two guide wheels 304 is equal to the distance between the outer walls of the two slide rails 2. The distance between the adjacent rolling surfaces of the guide wheels 304 is equal to the distance between the outer walls of the slide rails 2, forming precise guidance. This ensures that the roller carriage body 3 is parallel to the slide rails 2 during calibration, reducing calibration errors. The guide wheels 304 do not contact the slide rails 2, avoiding collision and wear during pushing, and improving the service life of the components. The rolling surfaces of the lower rollers 307 are all located below the body support 301. Adjacent rollers 307 roll and contact each other, forming a continuous support chain, which reduces vibration and noise, and automatically adapts to the slight deformation of the slide rail 2. The auxiliary components include L-shaped connecting plates 302 welded and fixed to the front and rear side walls of the car body bracket 301. The lower surface of each L-shaped connecting plate 302 is fixed with symmetrically arranged rotating shafts 303. The outer side walls of each rotating shaft 303 are rotatably connected with auxiliary calibration guide wheels 304. When the main body 3 of the roller carriage is installed on the slide rail 2, the main body 3 of the roller carriage is first placed on the slide rail 2 with one end tilted. The guide wheels 304 on both sides are clamped on the outside of the two slide rails 2 for calibration. After calibration, the main body 3 of the roller carriage is placed flat on the slide rail 2, which can ensure that the main body 3 of the roller carriage is parallel to the slide rail 2, reduce errors, and after long-term operation, the gap between the guide wheels 304 and the slide rail 2 can be observed to determine whether the main body 3 of the roller carriage is deviating on the slide rail 2. Manual adjustment can be made in time to avoid the cumulative error during long-distance movement, which may cause the roller carriage to derail or the furnace body to shift, thus improving the stability of the movement.

[0022] The working principle of this embodiment is as follows: When using it, when the main body 3 of the roller carriage is installed on the slide rail 2, firstly, the roller carriage main body 3 is placed on the slide rail 2 with one end tilted. The guide wheels 304 on both sides are clamped on the outside of the two slide rails 2 for calibration. After calibration, the roller carriage main body 3 is placed flat on the slide rail 2 to ensure that the roller carriage main body 3 is parallel to the slide rail 2. Then, it is connected to the hydraulic cylinder through the connecting lug 305 to realize automatic pushing. The roller carriage main body 3 is installed under the furnace body base through the mounting hole 3011 to complete the assembly. When pushing the furnace body, the hydraulic cylinder pushes the roller carriage main body 3, and the roller 307 rolls along the slide rail 2. After a long distance, the gap between the guide wheel 304 and the slide rail 2 can be observed to determine whether the main body 3 of the roller trolley is deviating on the slide rail 2, and timely calibration can be performed.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the scope of protection of the present utility model.
