Description

Technical Field

[0001] The utility model patent relates to a converter slag-blocking rod placing device in the metallurgical industry, and further relates to a novel suspended slag-blocking rod placing device. Background Art

[0002] The use of slag stopper rods for slag stopping in the later stage of converter has been widely studied and applied. At present, the mainstream forms of slag stopper rod placing devices mainly include floor-standing type and hanging type slag stopper rod placing devices. These two forms have their own advantages and disadvantages, and the selection should be made according to the conditions on site and the actual needs of the steel plant.

[0003] The floor-standing type runs on ground tracks, has stable operation, can be operated manually or remotely, and is convenient for maintenance, but it occupies the platform space behind the converter, which is not conducive to the movement of personnel and materials on the platform.

[0004] The suspended type runs on an aerial track and does not occupy the platform space behind the converter, which is convenient for the movement of personnel and materials on the platform. It runs stably and can be operated by remote control, but it is not conducive to maintenance, especially the height of the space. The utility model patent "Suspended slag blocking rod placing device" applied by Chinese patent 201210155466.X requires the space height behind the furnace to be greater than 3.5m, and it cannot be used if it is less than 3.5m. Utility Model Content

[0005] In order to solve the above-mentioned problem of the hanging slag-blocking rod placing device, the utility model aims to provide a novel hanging slag-blocking rod placing device.

[0006] To achieve the above purpose, the utility model provides a novel suspended slag blocking rod delivery device, comprising: a traveling unit having a driven wheel pair and a driving wheel pair; a rotating unit is installed below the traveling unit, and a slag blocking rod delivery device is suspended under the rotating unit.

[0007] Furthermore, a positioning locking device is provided on the rotating unit to position the rotating hanger after it is rotated to a predetermined angle.

[0009] Furthermore, the rotating unit includes: a rotating hanger, a slewing support bearing, a fixed gear, a rotating reducer component and a cantilever rod component, wherein the rotating hanger is fixed to the outer ring of the slewing support bearing, and the inner ring of the slewing support bearing is fixed to the suspension platform so that the rotating hanger can rotate freely; the fixed gear is fixed to the bottom of the suspension platform, the cantilever rod component is fixedly installed on the rotating hanger, the rotating reducer component is installed on the cantilever rod component, and the power output gear of the rotating reducer is meshed with the fixed gear.

[0010] Furthermore, a split hydraulic station is installed on the suspension platform.

[0011] Furthermore, the cantilever rod component includes a suspension frame, a cantilever rod is hinged at the lower end of the suspension frame, and a counterweight is arranged at the tail of the cantilever rod; a drive cylinder, one end of the drive cylinder is hinged at the tail of the cantilever rod, and the other end is hinged to the upper section of the suspension frame.

[0012] Furthermore, a rod throwing angle indicator is installed on the cantilever rod component. When the suspended slag blocking rod throwing device determines the parking position, the cantilever rod component clamps the slag blocking rod at an angle α. Through the extension and retraction of the driving rod, the cantilever rod component rotates to an angle of 90°-α on the angle indicator and then throws the rod.

[0013] Furthermore, a protective cover is installed below the suspension platform.

[0014] To achieve the above object, the utility model provides a novel suspended slag blocking rod placing method, wherein the method is carried out using the novel suspended slag blocking rod placing device, and comprises the following steps:

[0015] When the rotating part and the non-rotating part are at 90°, the slag blocking rod is installed, and the slag blocking rod forms an acute angle α with the front end of the cantilever rod component;

[0016] The rotating reducer component is started, the output gear of the rotating reducer component meshes with the fixed gear 4, the outer ring of the slewing support bearing rotates, causing the rotating part to rotate -90°, and the locking plug rod 11.2 driven by the hydraulic cylinder is inserted into the locking plug hole 11.1 to fix the rotating part;

[0017] The driving wheel pair 8 works to drive the whole equipment to move toward the converter; the movement deceleration and parking of the equipment are controlled by the double proximity switches to achieve precise parking;

[0018] After parking, the oil cylinder in the cantilever rod component 10 is retracted, and the front end of the cantilever rod component 10 is tilted down by 90°-α angle (the front end of the cantilever rod component 10 is horizontal 0° before delivery), so that the slag blocking rod is delivered vertically, realizing accurate vertical delivery.

[0019] Furthermore, the method further comprises the following steps:

[0020] After being put into operation, the oil cylinder in the arm member 10 extends to make the arm member 10 exit the converter at a horizontal angle of 0°.

The rotating reducer member 7 is started to make the rotating part and the non-rotating part at an angle of 90° to complete a working cycle.

[0021] The utility model discloses a novel suspended slag-blocking rod placing device, which clamps the slag-blocking rod through the cantilever rod component, and after the rotating reducer component drives the rotating hanger and the cantilever rod component to rotate into place, the locking device locks the rotating hanger and the hanging hanger, and the driving wheel pair drives the entire equipment to move toward the converter. After moving into place, the hydraulic cylinder in the cantilever rod component rotates the cantilever rod component by telescoping, and the rod is released after rotating to the calculated angle.

[0028] The embodiments of the utility model are described in detail below with reference to the accompanying drawings.

[0029] In the description of the present invention, it should be understood that the terms "center", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0030] The terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, unless otherwise specified, "plurality" means two or more.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0032] according to Figure 1 and Figure 2 The utility model patent mainly consists of two parts. The first part is the non-rotating part, which is mainly responsible for the overall movement of the equipment and the arrangement of parts and components, including a traveling frame 1, a suspension platform 2, a driven wheel pair 3, a fixed gear 4, a driving wheel pair 8, a locking socket 11.1, and a split hydraulic station 12. The split hydraulic station 12 is used to provide power for each hydraulic cylinder in this system.

[0033] The second part, the rotating part, has the main function of rotating 90° after the equipment exits the converter to install the slag stop rod and perform the subsequent rod throwing action. It includes a rotating hanger 5, a rotating reducer component 7, a protective cover 9, a cantilever rod component 10, and a locking plunger 11.2 driven by a hydraulic cylinder. When the second part is rotated 90° after the slag stop rod is installed and before the entire equipment moves (during normal rod throwing, the rotating part and the non-rotating part are defined as 0°), the locking mechanism 11 works to fix the rotating part and the non-rotating part relatively to prevent the cantilever rod component from shaking during rod throwing.

[0034] In the non-rotating part, the traveling frame 1 is installed with a driven wheel pair 3 and a driving wheel pair 8, and the suspension platform 2 is installed below the traveling frame 1. The locking socket 11.1, the split hydraulic station 12 and electrical components are placed on the suspension platform 2. The driving wheel pair 8 drives the traveling frame 1 to drive the equipment to move forward and backward as a whole; the inner ring of the slewing support bearing 6 and the fixed gear 4 are fixed to the suspension platform 2, and the suspension platform 2 is connected to the driving wheel pair 8. Figure 4 shown.

[0035] In the rotating part, the upper part of the rotating hanger 5 is fixed to the outer ring of the slewing support bearing 6 and the locking rod 11.2 driven by the hydraulic cylinder and can rotate with the outer ring. The lower part of the rotating hanger 5 is fixed to the cantilever rod component 10, which can drive the cantilever rod component 10 to rotate. The rotating reducer component 7 is installed on the platform of the cantilever rod component 10, and the protective cover 9 is also installed with the cantilever rod component 10. When the rotating reducer component 7 is started, the output gear of the rotating reducer component 7 is meshed with the fixed gear 4, which can drive the entire rotating part to rotate.

[0036] To sum up, the implementation process of the utility model patent is as follows: when the rotating part and the non-rotating part are at 90°, the slag blocking rod is installed, and the slag blocking rod and the front end of the cantilever rod component 10 form an acute angle α (calculated when CAD simulates the throwing of the rod), the rotating reducer component 7 is started, and the output gear of the rotating reducer component 7 is engaged with the fixed gear 4, and the outer ring of the slewing support bearing 6 rotates to rotate the rotating part -90°, and the locking plug 11.2 driven by the hydraulic cylinder is inserted into the locking socket 11.1 to fix the rotating part, and the driving wheel pair 8 works to drive the entire equipment to move toward the converter. The movement deceleration and parking of the equipment are controlled by the double proximity switch to achieve precise parking. After parking, the oil cylinder in the cantilever rod component 10 retracts, and the front end of the cantilever rod component 10 tilts down by 90°-α angle (the front end of the cantilever rod component 10 is horizontal 0° before throwing), so that the slag blocking rod is thrown vertically to achieve precise vertical throwing. After being put into operation, the oil cylinder in the arm member 10 extends to make the arm member 10 exit the converter at a horizontal angle of 0°. Before the rotating reducer member 7 is started again, the locking plunger 11.2 driven by the hydraulic cylinder is separated from the locking socket 11.1. The rotating reducer member 7 is started to make the rotating part and the non-rotating part at an angle of 90° to complete a working cycle.

[0037] The utility model is described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments, and various changes can be made within the knowledge of ordinary technicians in the field without departing from the purpose of the utility model. Many other changes and modifications that do not depart from the concept and scope of the utility model should be considered as the protection scope of the utility model.

[0038] In the description of this specification, specific features, structures, materials or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0039] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
