Description

The two-way dust gun 621 is connected to the connecting cover 311, and the flip shaft 62 is rotatably connected to the cross connecting plate 42. During the rotation of the cross connecting plate, the cross connecting plate can drive the flip shaft to rotate, wherein the collar and the push plate on the flip shaft slide along the positioning protrusion as a whole, and the positioning protrusion can drive the flip shaft to move left and right, so that when the flip shaft rotates, the left and right positions of the flip shaft change, and the two-way vacuum gun is pushed to move at this time, so that smoke and dust of different depths can be collected, and the driving gear on the flip shaft rotates on the gear ring, and the driving gear can drive the flip shaft to rotate, and the flip shaft drives the two-way vacuum gun to rotate, so as to change different vacuuming angles.

[0026] like Figures 1 to 10 As shown, in a specific implementation, a steel structure skeleton 11 is installed at the bottom of the operating table 1. The steel structure skeleton 11 is in a U-shape. The steel structure skeleton 11 can improve the structural strength of the equipment. Four supporting legs 111 are installed at the corners of the steel structure skeleton 11. Reinforcing ribs 112 are installed between adjacent supporting legs 111. The heights of adjacent reinforcing ribs 112 are different. The reinforcing ribs 112 can improve the overall stability of the equipment. The casting container 12 is located at the center of the operating table 1.

[0027] like Figures 1 to 10 As shown, further, a sealing gasket 211 is installed at the bottom of the sleeve 21, and the sealing gasket 211 is in contact with the surface of the operating table 1. A lifting ring 22 is installed at the top of the sealing cover 2, and an anti-slip cover is installed on the surface of the lifting ring 22. The lifting ring 22 on the sealing cover 2 is lifted by the gantry crane, and the sealing cover 2 and the sleeve 21 are driven to move by the lifting ring 22. When moved to the specified position, the casting container 12 can be sealed by the sleeve 21, and the sealing gasket 211 improves the sealing of the connection.

[0028] Embodiment 2: Based on the above embodiment, the difference between this embodiment and the present embodiment is that: Figures 1 to 10As shown, a rotating shaft 411 is installed at the output end of the driving motor 4, a connecting block 41 is installed at the end of the rotating shaft 411, the connecting block 41 is connected to the cross connecting plate 42, the connecting block 41 movably penetrates the connecting cover 311, the connecting cover 311 is annular, support frames 312 are installed on both sides of the connecting cover 311, and the support frames 312 are welded and set on the inner side wall of the sealing cover 2, an inner cavity is opened inside the connecting cover 311, and a slide plate 32 is rotatably installed inside the inner cavity, a collection pipe 321 is installed on the slide plate 32, and the end of the collection pipe 321 is located on the cross connecting plate 42. The rotating shaft 411 connected to the output shaft is driven to rotate by the driving motor 4, and the end of the rotating shaft 411 is connected to the connecting block 41, and at this time, the connecting block 41 drives the cross connecting plate 42 to start rotating as a whole.

[0029] like Figures 1 to 10 As shown, in a specific embodiment, a limit plate 422 is installed at the bottom of the vertical rod 421, and the diameter of the limit plate 422 is larger than the diameter of the vertical rod 421. A limit spring 423 is sleeved on the vertical rod 421 between the mounting plate 43 and the limit plate 422, and one end of the limit spring 423 is clamped on the mounting plate 43, and the other end of the limit spring 423 is clamped on the limit plate 422. In the process of the mounting plate 43 being raised as a whole, the mounting plate 43 slides on the vertical rod 421, and the limit spring 423 on the vertical rod 421 is stretched, and the stretched limit spring 423 is convenient for the later reset operation, and the limit plate 422 is installed at the bottom of the vertical rod 421, and the limit plate 422 ensures that the vertical rod 421 and the mounting plate 43 are not separated.

[0030] like Figures 1 to 10 As shown, further, a dust suction tube 441 is installed on the side vacuum gun 44, and a fixing seat 442 is installed on the dust suction tube 441, and the fixing seat 442 is welded to the bottom of the mounting plate 43, and a first elastic hose 443 is installed on the dust suction tube 441, and a transmission tube 444 is installed on the first elastic hose 443, and a collecting tube 321 is installed at the end of the transmission tube 444. This arrangement mainly discloses the connection method of the pipelines.

[0031] Embodiment 3: The difference between the above embodiment and this embodiment is that: like Figures 1 to 10As shown, a second elastic hose 622 is installed at the end of the collecting pipe 321, and the second elastic hose 622 movably penetrates the cross connecting plate 42. The end of the second elastic hose 622 is rotatably connected to the two-way dust gun 621. A rectangular shaft 61 is movably inserted inside the flip shaft 62, and the rectangular shaft 61 and the driving gear 6 are connected to each other. The rotation center of the driving gear 6 is slidably connected to the positioning slide rail 613 provided on the inner wall of the sleeve 21. When the flip shaft 62 rotates around the center of the sealing cover 2, the driving gear 6 rotates on the gear ring 51. At this time, the driving gear 6 can drive the rectangular shaft 61 to rotate, and the rectangular shaft 61 drives the entire flip shaft 62 to rotate. At this time, the flip shaft 62 drives the two-way dust gun 621 to rotate, thereby changing different dust suction angles.

[0032] like Figures 1 to 10 As shown, further, an annular partition plate 52 is installed on the positioning plate 5, a positioning protrusion 53 is installed on the annular partition plate 52, a limit seat 632 is slidably arranged on the flip shaft 62, the limit seat 632 is welded to the bottom of the cross connecting plate 42, a pressure plate 63 is rotatably installed on the flip shaft 62, a return spring 631 is sleeved on the flip shaft 62 located between the limit seat 632 and the pressure plate 63, the return spring 631 is clamped on the pressure plate 63 and the limit seat 632, a synchronization rod 64 is installed on the pressure plate 63, a synchronization slider 641 is installed on the synchronization rod 64, the synchronization slider 641 is slidably arranged on the synchronization rail 642, and the synchronization rail 642 is installed at the bottom of the cross connecting plate 42. When the flip shaft 62 moves, the position of the pressure plate 63 on the flip shaft 62 changes, and the pressure plate 63 squeezes the reset spring 631, which facilitates the subsequent reset operation. During the movement of the pressure plate 63, the synchronization rod 64 on the pressure plate 63 drives the synchronization slider 641 to slide on the synchronization slide rail 642, which ultimately achieves the purpose of limiting.

[0033] The implementation principle of a movable steelmaking dust collection and casting platform of this embodiment is as follows: When vacuuming is required, the operator uses the gantry crane to lift the lifting ring 22 on the sealing cover 2, and drives the sealing cover 2 and the sleeve 21 to move through the lifting ring 22. When they are moved to the specified position, the casting container 12 can be sealed through the sleeve 21, and the sealing gasket 211 improves the sealing of the connection.

[0034] Then the operator starts the smoking machine 3. At this time, the smoking machine 3 can start the side dust gun 44 through the connecting pipe 31, the connecting cover 311, the collecting pipe 321, the transmission pipe 444, the first elastic hose 443 and the dust suction pipe 441 to start working and complete the side dust suction operation. The smoking machine can also start the two-way dust gun 621 through the connecting pipe 31, the connecting cover 311, the collecting pipe 321 and the second elastic hose 622 to start working synchronously and complete the dust suction operation synchronously.

[0035] During the vacuuming operation, the operator first starts the drive motor 4, and the drive motor 4 drives the rotating shaft 411 connected to the output shaft to rotate. The end of the rotating shaft 411 is connected to the connecting block 41. At this time, the connecting block 41 drives the cross connecting plate 42 to rotate as a whole. The vertical rod 421 at the bottom of the cross connecting plate 42 can drive the mounting plate 43 to rotate axially, and a side vacuum gun 44 is installed at the bottom of the mounting plate 43. At this time, the position of the side vacuum gun 44 changes, and then the side vacuum gun 44 can vacuum the side of the casting container 12, reducing dead angles.

[0036] During the rotation of the mounting plate 43, the guide slider 431 on the mounting plate 43 slides along the spiral slide rail 432, so the overall height of the mounting plate 43 becomes higher, thereby driving the height of the lateral vacuum gun 44 to increase, which can increase the adsorption range.

[0037] When the mounting plate 43 becomes higher as a whole, the mounting plate 43 slides on the vertical rod 421, and the limit spring 423 on the vertical rod 421 is stretched, and the stretched limit spring 423 is convenient for the later resetting operation, and a limit plate 422 is installed at the bottom of the vertical rod 421, and the limit plate 422 ensures that the vertical rod 421 and the mounting plate 43 are not separated.

[0038] During the rotation of the cross connecting plate 42, the position of the limit seat 632 at the bottom of the cross connecting plate 42 changes, and the limit seat 632 can drive the flip shaft 62 to rotate, wherein the collar 611 and the push plate 612 on the flip shaft 62 slide along the positioning protrusion 53 as a whole. Since the surface of the positioning protrusion 53 is uneven, the flip shaft 62 can be driven to move left and right. At this time, the position of the flip shaft 62 changes, and the two-way dust gun 621 at the end of the flip shaft 62 moves. At this time, the two-way dust gun 621 continuously moves toward the inside of the sealing cover 2, and can collect smoke and dust of different depths. Moreover, the entire two-way dust gun 621 rotates with the cross connecting plate 42, so dust collection operations can be performed on different positions.

[0039] When the flip shaft 62 moves, the position of the pressure plate 63 on the flip shaft 62 changes, and the pressure plate 63 squeezes the reset spring 631, which facilitates the subsequent reset operation. During the movement of the pressure plate 63, the synchronization rod 64 on the pressure plate 63 drives the synchronization slider 641 to slide on the synchronization slide rail 642, which ultimately achieves the purpose of limiting.

[0040] When the flip shaft 62 rotates around the center of the sealing cover 2, the driving gear 6 rotates on the ring gear 51. The driving gear 6 can drive the rectangular shaft 61 to rotate, and the rectangular shaft 61 drives the entire flip shaft 62 to rotate. At this time, the flip shaft 62 drives the two-way vacuum gun 621 to rotate, thereby changing different vacuuming angles.

[0041] Through the above structure, the vacuuming part can be divided into two parts, one part is located at the side wall of the casting container 12, and the other part is located at the top of the casting container 12. The dust located on the side wall of the casting container 12 is vacuumed by the vacuum gun rotating and lifting the position, while the dust located on the top of the casting container 12 is vacuumed by the rotation of the two-way vacuum gun 621, and the position of the two-way vacuum gun 621 above the casting container 12 and the angle of the two-way vacuum gun 621 are controlled. Through the above comprehensive vacuuming method, the vacuuming effect can be better.
