Description

Technical Field

[0001] This invention belongs to the technical field of steelmaking equipment, specifically a converter oxygen lance transverse movement trolley positioning device. Background Technology

[0002] An oxygen lance is a tubular device that blows high-pressure, high-purity oxygen at supersonic speeds into the molten metal pool above a converter. It is also called a spray gun and is an important piece of equipment in oxygen top-blowing steelmaking.

[0003] Currently, when the oxygen lance is in operation, it needs to be moved laterally to the working position above the converter by a transverse trolley. Then, the lifting mechanism on the transverse trolley moves the oxygen lance down into the converter to blow oxygen into the molten metal pool for smelting. In actual operation, after the transverse trolley moves to the working position, it lacks a positioning mechanism, which leads to a large lateral sway of the transverse trolley. This results in poor stability of the oxygen lance and affects the normal blowing of the oxygen lance. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a converter oxygen lance transverse trolley positioning device.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A converter oxygen lance traverse positioning device includes a trolley body, a winch, a locking assembly, a first drive assembly, a second drive assembly, and an oxygen lance.

[0007] The vehicle body is equipped with wheels on top, and the oxygen lance is located at the bottom of the vehicle body.

[0008] The locking component, the first driving component, and the second driving component are disposed above the converter.

[0009] During the process of the vehicle body moving the oxygen lance laterally upwards towards the converter, the first drive assembly is used to move the locking assembly upwards, causing the locking assembly to move to the locked position.

[0010] When the vehicle body moves the oxygen lance laterally to a position directly above the converter, the locking assembly locks the vehicle body in response to the lateral movement.

[0011] The winch is located on the upper part of the car body and is used to drive the oxygen lance to move up and down. When the oxygen lance moves up and moves out of the converter, the second drive component drives the limiting component to move down, so that the locking component is removed from the locking position to release the lateral movement locking state of the car body.

[0012] As a further improvement of the present invention: a positioning block is fixedly provided on the side wall of the vehicle body, the positioning block has a positioning hole, and the bottom of the positioning block has an inclined surface.

[0013] The locking assembly includes a locking rod, a screw, and a second elastic element.

[0014] The screw has an insertion hole inside. The upper end of the locking rod extends above the screw, and the lower end extends from the top of the screw into the insertion hole and is movably engaged with the insertion hole. The second elastic element is disposed inside the insertion hole to provide elastic support for the locking rod.

[0015] As a further improvement of the present invention: a plurality of first helical toothed plates are hinged to the outer wall of the vehicle body, and the plurality of first helical toothed plates are linearly spaced along the lateral direction of the vehicle body. Each group of first helical toothed plates is connected to the outer wall of the vehicle body on one side by a set of first elastic members, the first elastic members being used to provide elastic support for the first helical toothed plates.

[0016] The first drive assembly includes a first spur gear, a threaded sleeve, and a fixing plate.

[0017] The fixing plate is fixed above the converter. The threaded sleeve is rotatably mounted on the upper part of the fixing plate. The lower end of the screw extends into the inside of the threaded sleeve and is threaded into the threaded sleeve. The upper end extends above the threaded sleeve. The first spur gear is fixed outside the threaded sleeve and can mesh unidirectionally with a plurality of first helical gears.

[0018] As a further improvement of the present invention: a guide rod is fixedly provided on the upper part of the fixing plate, a connecting rod is fixedly provided on the outer wall of the screw, a guide sleeve is fixedly provided at the end of the connecting rod away from the screw, and the guide sleeve is slidably provided outside the guide rod.

[0019] As a further improvement to the present invention: an oxygen lance mounting plate is fixedly provided on the top of the oxygen lance, and a first bevel gear is also fixedly provided on the outside of the threaded sleeve.

[0020] The second drive assembly includes a second spur gear, a support shaft, a second bevel gear, a support rod, a second helical gear plate, and a third elastic element.

[0021] The second spur gear and the second bevel gear are connected by the support shaft. The second bevel gear meshes with the first bevel gear. The support rod is fixedly mounted on the side wall of the oxygen lance mounting plate.

[0022] The second helical gear is provided in several groups. Several second helical gears are hinged on the side wall of the support rod and distributed vertically at intervals along the side wall of the support rod. Several second helical gears can mesh with the second spur gear in one direction. Each group of second helical gears is connected to the support rod on one side through a set of the third elastic members. The third elastic members are used to provide elastic support for the second helical gears.

[0023] As a further improvement of the present invention: a support is also fixedly provided on the upper part of the fixed plate, and the support shaft passes through the support and rotates with the support.

[0024] As a further improvement of the present invention: the first elastic element, the second elastic element and the third elastic element are springs or metal sheets.

[0025] Compared with the prior art, the beneficial effects of the present invention are:

[0026] In this embodiment of the invention, when oxygen blowing smelting is required on the molten metal pool inside the converter, the traveling wheels roll along the slide rails, and the vehicle body moves the oxygen lance laterally upwards towards the converter. During this process, the first driving component moves the locking component upwards, causing the locking component to move to the locked position. Subsequently, as the vehicle body and the oxygen lance continue to move, when the oxygen lance moves to a position directly above the converter, the locking component locks against the lateral movement of the vehicle body. Then, the winch moves the oxygen lance downwards, and the oxygen lance enters the converter to perform oxygen blowing smelting on the molten metal pool inside the converter. After smelting... Afterwards, the winch moves the oxygen lance upwards. When the oxygen lance moves out of the converter, the second drive assembly moves the locking assembly downwards, and the locking assembly is removed from the locked position, thereby releasing the car body from its locked state. Then, the car body slides in the opposite direction along the slide rail, and the car body moves the oxygen lance back to its reset position. Compared with the existing technology, when the car body moves the oxygen lance laterally to the position directly above the converter, it can perform lateral locking and positioning of the car body, thereby improving the stability of the car body, and thus improving the stability of the oxygen lance in the oxygen blowing smelting process and improving the oxygen blowing smelting effect of the molten metal pool.

Detailed Implementation

[0033] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0034] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0035] Please see Figure 1 as well as Figure 2 This embodiment provides a converter oxygen lance traverse positioning device, including a car body 10, a winch 30, a locking assembly 40, a first drive assembly 50, a second drive assembly 60, and an oxygen lance 70. The car body 10 is equipped with wheels 101 on its top, and the oxygen lance 70 is located at the bottom of the car body 10. The locking assembly 40, the first drive assembly 50, and the second drive assembly 60 are positioned above the converter (not shown in the figure). During the process of the car body 10 moving the oxygen lance 70 laterally upwards towards the converter, the first drive assembly 50 is used to drive the oxygen lance 70... The locking component 40 moves upward, causing it to move to the locked position. When the car body 10 moves the oxygen lance 70 laterally to a position directly above the converter, the locking component 40 locks the lateral movement of the car body 10. The winch 30 is located on the upper part of the car body 10 and is used to drive the oxygen lance 70 to move up and down. When the oxygen lance 70 moves upward and moves out of the converter, the second drive component 60 drives the limiting component 40 downward, causing the locking component 40 to be removed from the locked position, thereby releasing the lateral movement locking state of the car body 10.

[0036] When oxygen blowing is required for smelting the molten metal pool inside the converter, the traveling wheel 101 rolls along the slide rail 20, and the car body 10 moves the oxygen lance 70 laterally upwards. During this process, the first drive component 50 moves the locking component 40 upwards, causing the locking component 40 to move to the locked position. Then, as the car body 10 and the oxygen lance 70 continue to move, when the oxygen lance 70 moves to the position directly above the converter, the locking component 40 locks against the lateral movement of the car body 10. Then, the winch 30 moves the oxygen lance 70 downwards, and the oxygen lance 70 enters the converter to perform oxygen blowing for smelting the molten metal pool inside the converter. After smelting is completed, the winch 30 moves the oxygen lance 70 upwards. When the oxygen lance 70 moves out of the converter, the second drive component 60 moves the locking component 40 downwards, and the locking component 40 is removed from the locked position, thereby releasing the locked state of the car body 10. Then, the traveling wheel 101 slides in the opposite direction along the slide rail 20, and the car body 10 moves the oxygen lance 70 back to its original position.

[0037] Please see Figure 1 as well as Figure 3 In one embodiment, a positioning block 102 is fixedly provided on the side wall of the vehicle body 10. The positioning block 102 has a positioning hole 103 and a slope 104 at its bottom. The locking assembly 40 includes a locking rod 401, a screw 402 and a second elastic member 404. The screw 402 has an insertion hole inside. The upper end of the locking rod 401 extends above the screw 402, and the lower end extends from the top of the screw 402 into the insertion hole and is movably engaged with the insertion hole. The second elastic member 404 is disposed inside the insertion hole to provide elastic support for the locking rod 401.

[0038] As the car body 10 moves the oxygen lance 70 upwards towards the converter, the car body 10 moves the positioning block 102 synchronously. The first drive assembly 50 moves the screw 402, locking rod 401, and second elastic element 404 upwards synchronously. After the locking rod 401 moves to the locked position, as the car body 10 continues to move, the inclined surface 104 at the bottom of the positioning block 102 acts on the upper end of the locking rod 401, thereby pushing the locking rod 401 into the insertion hole, causing the second elastic element 404 to compress. The upper end of the locking rod 401 relative to the inclined surface... When the oxygen lance 70 moves to the position directly above the converter, the upper end of the locking rod 401 is aligned with the positioning hole 103. The second elastic element 404 pushes the locking rod 401 to move it upward. The upper end of the locking rod 401 is inserted into the positioning hole 103, thereby locking the car body 10. After the car body 10 is locked, it cannot continue to move laterally, thus completing the positioning of the car body 10 and the oxygen lance 70. This ensures that the oxygen lance 70 can be accurately moved down into the converter, thereby improving the oxygen blowing smelting effect of the molten metal pool.

[0039] Please see Figure 1 as well as Figure 4In one embodiment, a plurality of first helical gears 105 are hinged to the outer wall of the vehicle body 10. The plurality of first helical gears 105 are linearly spaced along the lateral direction of the vehicle body 10. Each group of first helical gears 105 is connected to the outer wall of the vehicle body 10 on one side by a group of first elastic members 106. The first elastic members 106 are used to provide elastic support for the first helical gears 105. The first drive assembly 50 includes a first spur gear 501, a threaded sleeve 502, and a fixing plate 505. The fixing plate 505 is located above the converter. In a fixed state, specifically, the fixing plate 505 can be directly fixed to the top of the converter, or it can be fixed to the position above the converter by other means. There is no limitation here. The threaded sleeve 502 is rotatably installed on the upper part of the fixing plate 505. The lower end of the screw 402 extends into the inside of the threaded sleeve 502 and is threadedly engaged with the threaded sleeve 502. The upper end extends above the threaded sleeve 502. The first spur gear 501 is fixedly disposed outside the threaded sleeve 502 and can mesh unidirectionally with a plurality of first helical gears 105.

[0040] During the lateral movement of the oxygen lance 70 upwards from the converter by the car body 10, several first helical gears 105 on the outer wall of the car body 10 mesh sequentially with the first spur gear 501 under the elastic support of several first elastic elements 106, thereby driving the first spur gear 501 and the threaded sleeve 502 to rotate. When the threaded sleeve 502 rotates, it drives the screw 402, the second elastic element 404, and the locking rod 401 to move upwards through the threaded engagement with the screw 402. After the several first helical gears 105 disengage from the first spur gear 501, the threaded sleeve 502 stops rotating, and the screw 402... The second elastic element 404 and the locking rod 401 stop moving upward. At this time, the locking rod 401 moves upward to the locked position. Subsequently, as the car body 10 drives the oxygen lance 70 to continue moving, the inclined surface 104 at the bottom of the positioning block 102 acts on the upper end of the locking rod 401, thereby pushing the locking rod 401 downward, causing the second elastic element 404 to be compressed. When the oxygen lance 70 moves to the position directly above the converter, the upper end of the locking rod 401 is directly opposite the positioning hole 103. The second elastic element 404 pushes the locking rod 401 upward, and the upper end of the locking rod 401 is inserted into the positioning hole 103 to lock the car body 10 and the oxygen lance 70 laterally.

[0041] Please see Figure 1 as well as Figure 3 In one embodiment, a guide rod 503 is fixedly disposed on the upper part of the fixing plate 505, a connecting rod 403 is fixedly disposed on the outer wall of the screw 402, and a guide sleeve 405 is fixedly disposed at the end of the connecting rod 403 away from the screw 402, and the guide sleeve 405 is slidably disposed outside the guide rod 503.

[0042] Through the sliding engagement of the guide sleeve 405 and the guide rod 503, when the first helical gear 105 meshes with the first spur gear 501 and drives the threaded sleeve 502 to rotate, the threaded sleeve 502 can smoothly and steadily drive the screw 402, the second elastic element 404 and the locking rod 401 to move upward, so that the locking rod 401 can move smoothly to the locking position.

[0043] Please see Figure 2 as well as Figure 5 In one embodiment, an oxygen lance mounting plate 701 is fixedly disposed on the top of the oxygen lance 70, and a first bevel gear 504 is also fixedly disposed on the outside of the threaded sleeve 502. The second drive assembly 60 includes a second spur gear 601, a support shaft 602, a second bevel gear 603, a support rod 604, a second helical gear 605, and a third elastic element 606. The second spur gear 601 and the second bevel gear 603 are connected through the support shaft 602, and the second bevel gear 603 meshes with the first bevel gear 504. The support rod 604... 04 is fixedly mounted on the side wall of the oxygen lance mounting plate 701. The second helical gear 605 is provided in several groups. Several second helical gears 605 are hinged to the side wall of the support rod 604 and are vertically spaced along the side wall of the support rod 604. Several second helical gears 605 can mesh with the second spur gear 601 in one direction. Each group of second helical gears 605 is connected to the support rod 604 on one side through a group of third elastic members 606. The third elastic members 606 are used to provide elastic support for the second helical gears 605.

[0044] After the upper end of the locking rod 401 is inserted into the positioning hole 103 to lock the car body 10 and the oxygen lance 70 laterally, the support rod 604 moves laterally to one side of the second spur gear 601, and several second helical gears 605 contact the second spur gear 601. Then, the winch 30 drives the oxygen lance mounting plate 701 and the oxygen lance 70 to move downwards, and the oxygen lance 70 enters the converter to perform oxygen blowing smelting on the molten metal pool. When the oxygen lance mounting plate 701 moves downwards, it can drive the support rod 604 and several second helical gears 605 to move downwards simultaneously. 5. The oxygen lance 601 is pushed by the second spur gear 601 and deflected in sequence toward the support rod 604. Several second helical gears 605 cannot mesh with the second spur gear 601, and the second spur gear 601 remains stationary. After the oxygen blowing smelting of the molten metal is completed, the winch 30 drives the oxygen lance mounting plate 701, oxygen lance 70, support rod 604, and several second helical gears 605 to move upward. After the oxygen lance 70 is removed from the converter, as the support rod 604 and several second helical gears 605 continue to move upward, several second helical gears 605... The two helical gears 605, supported by several third elastic elements 606, mesh sequentially with the second spur gear 601, thereby driving the second spur gear 601 to rotate. The second spur gear 601 drives the second bevel gear 603 to rotate via the support shaft 602. The meshing of the second bevel gear 603 with the first bevel gear 504 drives the threaded sleeve 502 to rotate in the opposite direction. When the threaded sleeve 502 rotates in the opposite direction, it drives the screw 402 to move downward through the reverse thread engagement with the screw 402, thereby driving the second elastic element 404 and the lock. As rod 401 moves downward, the upper end of locking rod 401 exits from the positioning hole 103, thereby releasing the lateral movement locking state of vehicle body 10 and oxygen lance 70. Subsequently, the traveling wheel 101 rolls in the opposite direction along slide rail 20, and vehicle body 10 drives oxygen lance 70 to return to reset. During the return and reset process of vehicle body 10, several first helical gears 105 act in the opposite direction on the first spur gear 501 and are pushed by the first spur gear 501 to deflect sequentially in the direction of vehicle body 10. Several first helical gears 105 cannot mesh with the first spur gear 501, and threaded sleeve 502 remains stationary.

[0045] Please see Figure 2 In one embodiment, a support 506 is also fixedly provided on the upper part of the fixing plate 505, and the support shaft 602 passes through the support 506 and rotates with the support 506.

[0046] The support 506 provides rotational support for the support shaft 602, enabling the second spur gear 601 and the second bevel gear 603 to rotate synchronously.

[0047] In one embodiment, the first elastic element 106, the second elastic element 404, and the third elastic element 606 can be springs or metal sheets, and there is no limitation here.

[0048] In this embodiment of the invention, when oxygen blowing smelting is required on the molten metal pool inside the converter, the traveling wheels 101 roll along the slide rail 20, and the vehicle body 10 drives the oxygen lance 70 to move laterally upwards above the converter. During this process, the first drive assembly 50 drives the locking assembly 40 to move upwards, causing the locking assembly 40 to move to the locked position. Subsequently, as the vehicle body 10 and the oxygen lance 70 continue to move, when the oxygen lance 70 moves to the position directly above the converter, the locking assembly 40 locks against the lateral movement of the vehicle body 10. Then, the winch 30 drives the oxygen lance 70 downwards, and the oxygen lance 70 enters the converter to perform oxygen blowing smelting on the molten metal pool inside the converter. After smelting is completed... Then, the winch 30 drives the oxygen lance 70 to move upward. When the oxygen lance 70 moves out of the converter, the second drive assembly 60 drives the locking assembly 40 to move downward. The locking assembly 40 is removed from the locked position, thereby releasing the locked state of the car body 10. Then, the traveling 101 slides in the opposite direction along the slide rail 20, and the car body 10 drives the oxygen lance 70 back to the reset position. Compared with the prior art, when the car body 10 drives the oxygen lance 70 to move laterally to the position directly above the converter, it can perform lateral locking and positioning on the car body 10, thereby improving the stability of the car body 10, and thus improving the stability of the oxygen lance 70 in the oxygen blowing smelting process and improving the oxygen blowing smelting effect of the molten metal pool.

[0049] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
