Description

Technical Field

[0001] This invention relates to the field of converter tapping technology, and in particular to a traveling device for a converter tapping hole drilling machine. Background Technology

[0002] The top and bottom combined blowing technology of converters integrates many advantages of oxygen top blowing converter technology and oxygen bottom blowing converter technology. It has superior performance in reducing iron oxide content in slag, increasing metal yield, and reducing ferroalloy consumption. It has been widely used by domestic steelmaking enterprises. However, in the application of this technology, it has been found that the permeable bricks used in the furnace are damaged quickly due to the very harsh operating conditions, so they cannot be synchronized with the furnace age.

[0003] A patent with publication number CN205313598U discloses an online drilling machine for replacing permeable bricks at the bottom of a converter. The machine includes an operating platform and a frame. An electric hoist and an I-beam track are mounted on the top of the operating platform. A straight flange is located at the front of the frame, and a positioning device is installed on the flange. A drill bit is nested within the positioning device. The drill bit is connected to a drilling machine mounted on a drilling platform. The left connector of the drilling machine is connected to a power box, and the right faucet is connected to a water tank. An automatic drilling machine that senses the drill bit passing through material is attached to the drilling platform. A track is provided under the drilling platform, allowing the drilling machine to move along the track when the automatic drilling machine is activated. This invention can protect the permeable bricks during multiple replacements and synchronize them with the age of the converter's bottom bricks, thus enabling safe and reliable re-blowing of the converter throughout its service life.

[0004] As an important tool for changing the tapping hole in the converter, the drilling machine was found to be using a lead screw running mechanism during on-site inspection. After 2-3 uses, the lead screw deformed and wore, causing the gap between the lead screw and the piston to increase. This resulted in the drilling machine running idle under load, requiring a forklift to replace the screw, which was inefficient. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the problem in the prior art that the deformation and wear of the lead screw leads to an increase in the gap between the lead screw and the piston, which causes the drilling machine to idle under load, and at the same time requires the assistance of a forklift for replacement, resulting in low efficiency.

[0006] To solve the above-mentioned technical problems, the present invention provides a traveling device for a converter tapping hole drilling machine, including a traveling support frame, a motor and a lap plate movably sleeved on the inner wall of the traveling support frame, a swing support frame swayingly connected to the inner wall of the traveling support frame at the middle position, limit strips fixedly connected to the inner walls of both sides of the swing support frame, a hydraulic rod fixedly installed on the inner wall of one end of the swing support frame, a slider movably lapped on the inner wall of the swing support frame fixedly connected to the output end of the hydraulic rod, the outer surface of the motor fixedly installed on the outer surface of the slider, the outer surface of the lap plate disposed on the outer surface of the other end of the swing support frame, and jet generators fixedly installed on the two surfaces of the slider.

[0007] In one embodiment of the present invention, a limiting sleeve is fixedly installed on one end of the overlapping plate, and a water tank is fixedly installed on the top surface of the overlapping plate and at the two side edges, and the output end of the water tank extends to the inner wall of the limiting sleeve.

[0008] In one embodiment of the present invention, a snap-fit ​​support frame is fixedly installed on the top surface of the overlapping plate and at one side edge position. The surface of the snap-fit ​​support frame is located at the middle position of two sets of limiting sleeves, and a limiting rotating ring is movably sleeved on the inner wall surface of the snap-fit ​​support frame.

[0009] In one embodiment of the present invention, transmission toothed rings are provided on both sides of the limiting rotating ring, a limiting ring is fixedly installed on the inner wall of the limiting rotating ring, and a scraping wire is provided on the inner wall of the limiting ring.

[0010] In one embodiment of the present invention, a second motor is fixedly installed on the top surface of the overlapping plate and at one side edge of the water tank. A push chuck is fixedly connected to the output end of the second motor, and the outer surface of the push chuck is movably overlapped with the outer surface of the transmission tooth ring.

[0011] In one embodiment of the present invention, a limiting sleeve is fixedly connected to the output end of the motor, a shim support strip is fixedly installed on the inner side wall of the limiting sleeve, and a limiting rod is fixedly installed on the top inner side wall of the limiting sleeve.

[0012] In one embodiment of the present invention, a swing arm plate is movably sleeved on the outer surface of the limiting rod, and a pull-back wire is provided on the top inner wall of the limiting collar.

[0013] In one embodiment of the present invention, an extrusion plate is fixedly connected to the other end of the rewind wire, and a drill bit is movably sleeved on the outer surface of the shim support strip and the extrusion plate.

[0014] In one embodiment of the present invention, a fixing block is fixedly installed on the top surface of the walking support frame and at the bottom edge of the overlapping plate, and a damping rod is fixedly installed on one side surface of the fixing block.

[0015] In one embodiment of the present invention, an elastic buffer wire is movably sleeved on the outer surface of the damping rod, and a sealing disc is fixedly installed on one end of the damping rod.

[0016] The technical solution of the present invention has the following advantages compared with the prior art:

[0017] The present invention discloses a traveling device for a converter tap hole drilling machine. When drilling in a converter, the swing support frame is swung to adjust the rotation amplitude. By using the tilting angle, drilling can be performed on converters at different positions and heights. When the swing support frame is adjusted to the required angle, it is pushed by a hydraulic rod. At this time, the position of the slider is limited by the limiting strip on the inner wall of the swing support frame, so that the slider can move horizontally, avoiding shaking when the motor moves, reducing the phenomenon of idling when the drilling machine is under load, and eliminating the need for a forklift to move it.

[0018] The traveling device of the converter tap hole drilling machine described in this invention, when the first motor retracts after drilling, works in conjunction with the second motor to rotate the push chuck, which in turn pushes the transmission tooth rings on both sides of the limiting rotating ring, causing the limiting rotating ring to rotate under the constraint of the clamping support frame. During the rotation of the limiting rotating ring, the limiting ring rotates on the surface of the first motor. When the drill head moves inside the limiting ring, the scraping wire on the inner wall of the limiting ring scrapes and washes away the residual iron filings on the surface of the drill head, achieving the effect of cleaning off the residue.

[0019] The present invention describes a traveling device for a converter tap hole drilling machine. When the drilling head moves inside the limiting sleeve, a water tank is used to inject high-pressure gas into the limiting sleeve. The gas is blown into the recessed area on the inner wall of the limiting sleeve, and the gas flows rapidly on the surface of the drilling head. This cools the converter molten steel on the surface of the drilling head at a low temperature, causing the molten steel to solidify quickly. The steel is then scraped off by the limiting ring later.

[0020] The traveling device of the converter tapping hole drilling machine described in this invention, when the drilling head has been drilling for a long time and is being periodically maintained and repaired, connects a new drilling head to the inside of the limiting sleeve, and uses a support pad to limit the position of the drilling head. At this time, the swing arm plate is swung and the shorter end of the swing arm plate is used to press down on the surface of the extrusion plate, so that the extrusion plate is tightly attached to the outer surface of the drilling head. The rectangular shape of the support pad and the extrusion plate limits the position of the drilling head. Attached Figure Description

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, so that those skilled in the art can better understand and implement the present invention. However, the embodiments described are not intended to limit the present invention.

[0031] Please see Figure 1 - Figure 2 and Figures 6-7 The present invention provides a traveling device for a converter tap hole drilling machine, including a traveling support frame 11, a motor 12 and a lap plate 13 movably sleeved on the inner wall of the traveling support frame 11, a swing support frame 111 swingingly connected to the inner wall of the traveling support frame 11 at the middle position, limit strips 112 fixedly connected to the inner walls on both sides of the swing support frame 111, a hydraulic rod 113 fixedly installed on the inner wall of one end of the swing support frame 111, a slider 114 movably lapped on the inner wall of the swing support frame 111 fixedly connected to the output end of the hydraulic rod 113, the outer surface of the motor 12 fixedly installed on the outer surface of the slider 114, the outer surface of the lap plate 13 is set on the outer surface of the other end of the swing support frame 111, and jet generators 115 are fixedly installed on the two sides of the slider 114.

[0032] When drilling holes in the converter, the swing support frame 111 is swung to adjust the rotation amplitude. By using the tilting angle, drilling can be performed on converters at different positions and heights. When the swing support frame 111 is adjusted to the required angle, it is used in conjunction with the hydraulic rod 113 to push the slider 114. At this time, the position of the slider 114 is limited by the limiting strip 112 on the inner wall of the swing support frame 111, so that the slider 114 can move horizontally, avoiding the shaking of the motor 12 when it moves, reducing the phenomenon of idling when the drilling machine is under load, and eliminating the need for a forklift to transfer the machine.

[0033] After the drilling of motor 12 is completed, it retracts. At this time, the overlapping plate 13 is used to clean the debris from the surface of motor 12. At the same time, the jet 115 sprays gas onto the surface of motor 12. This process not only washes away the debris on the surface of motor 12, but also cools down the residual temperature on the surface of motor 12.

[0034] Furthermore, such as Figures 3-4 and Figure 6As shown, a limiting sleeve 131 is fixedly installed on one end of the overlapping plate 13. A water tank 132 is fixedly installed on the top surface of the overlapping plate 13 and at the two side edges. The output end of the water tank 132 extends to the inner wall of the limiting sleeve 131. A snap-fit ​​support frame 139 is fixedly installed on the top surface of the overlapping plate 13 and at one side edge. The surface of the snap-fit ​​support frame 139 is located in the middle of the two sets of limiting sleeves 131. A limiting rotating ring 135 is movably sleeved on the inner wall of the snap-fit ​​support frame 139. A transmission toothed ring 136 is provided on both sides of the limiting rotating ring 135. A limiting ring 137 is fixedly installed on the inner wall of the limiting rotating ring 135. A scraping wire 138 is provided on the inner wall of the limiting ring 137. A motor 133 is fixedly installed on the top surface of the overlapping plate 13 and on one side edge of the water tank 132. A push chuck 134 is fixedly connected to the output end of the motor 133. The outer surface of the push chuck 134 is movably overlapped on the outer surface of the transmission toothed ring 136.

[0035] When motor 12 retracts after drilling, it works in conjunction with motor 2 133 to rotate the push chuck 134, which in turn pushes the transmission tooth rings 136 on both sides of the limiting rotating ring 135. This causes the limiting rotating ring 135 to rotate under the constraint of the clamping support frame 139. As the limiting rotating ring 135 rotates, it drives the limiting ring 137 to rotate on the surface of motor 12. When the drill head 127 moves inside the limiting ring 137, it works in conjunction with the scraping wire 138 on the inner wall of the limiting ring 137 to scrape and flush away the residual iron filings on the surface of the drill head 127, thus cleaning up the residue.

[0036] When the drill head 127 moves inside the limiting sleeve 131, it works in conjunction with the water tank 132 to inject high-pressure gas into the limiting sleeve 131. The gas is blown into the recessed area on the inner wall of the limiting sleeve 131, and the gas flows rapidly on the surface of the drill head 127, thereby cooling the converter steel on the surface of the drill head 127 at a low temperature and causing the steel to solidify rapidly. Later, the steel is scraped off by the limiting ring 137.

[0037] Furthermore, such as Figure 6 and Figure 7As shown, a limiting collar 121 is fixedly connected to the output end of motor 12. A shim support strip 126 is fixedly installed on the inner wall of the limiting collar 121. A limiting rod 122 is fixedly installed on the top inner wall of the limiting collar 121. A swing arm plate 123 is movably sleeved on the outer surface of the limiting rod 122. A pull-back wire 124 is provided on the top inner wall of the limiting collar 121. A compression soft plate 125 is fixedly connected to the other end of the pull-back wire 124. A drill bit 127 is movably sleeved on the outer surface of the shim support strip 126 and the compression soft plate 125.

[0038] When the drill bit 127 has been drilling for a long time and is being maintained and repaired, a new drill bit 127 is connected to the inside of the limiting sleeve 121, and the position of the drill bit 127 is limited by the support strip 126. At this time, the swing arm plate 123 is swung and the shorter end of the swing arm plate 123 is used to press down on the surface of the extrusion plate 125, so that the extrusion plate 125 is tightly attached to the outer surface of the drill bit 127. The rectangular shape of the support strip 126 and the extrusion plate 125 is used to limit the position of the drill bit 127.

[0039] Furthermore, such as Figure 5 As shown, a fixing block a1 is fixedly installed on the top surface of the walking support frame 11 and at the bottom edge of the overlapping plate 13. A damping rod a2 is fixedly installed on one side surface of the fixing block a1. An elastic buffer wire a3 is movably sleeved on the outer side surface of the damping rod a2. A sealing disc a4 is fixedly installed on one end of the damping rod a2.

[0040] After replacing the new drill bit 127 and drilling, one end of the traveling support frame 11 is attached to the surface of the converter, so that the sealing disc a4 is attached to the surface where drilling is required. The position of the sealing disc a4 is limited by the damping rod a2 and the elastic buffer wire a3.

[0041] Working principle: When drilling holes in the converter, the swing support frame 111 is swung to adjust the rotation amplitude. By using the tilting angle, drilling can be performed on converters at different positions and heights. When the swing support frame 111 is adjusted to the required angle, it works with the hydraulic rod 113 to push the slider 114. At this time, the limiting strip 112 on the inner wall of the swing support frame 111 limits the position of the slider 114, so that the slider 114 can move horizontally, avoiding the shaking of the motor 12 when it moves, reducing the phenomenon of idling when the drilling machine is under load, and eliminating the need for a forklift to transfer the machine.

[0042] After the drilling of motor 12 is completed, it retracts. At this time, the overlapping plate 13 is used to clean the debris on the surface of motor 12. At the same time, the jet 115 sprays gas on the surface of motor 12. This process washes and cleans the debris on the surface of motor 12 and cools the residual temperature on the surface of motor 12.

[0043] When motor 12 retracts after drilling, it works in conjunction with motor 2 133 to rotate the push chuck 134, which in turn pushes the transmission tooth rings 136 on both sides of the limiting rotating ring 135. This causes the limiting rotating ring 135 to rotate under the constraint of the clamping support frame 139. As the limiting rotating ring 135 rotates, it drives the limiting ring 137 to rotate on the surface of motor 12. When the drill head 127 moves inside the limiting ring 137, it works in conjunction with the scraping wire 138 on the inner wall of the limiting ring 137 to scrape and flush away the residual iron filings on the surface of the drill head 127, thus cleaning up the residue.

[0044] When the drill head 127 moves inside the limiting sleeve 131, it works with the water tank 132 to inject high-pressure gas into the limiting sleeve 131. The gas is blown into the recessed area on the inner wall of the limiting sleeve 131, and the gas flows rapidly on the surface of the drill head 127, thereby cooling the converter steel on the surface of the drill head 127 at a low temperature and causing the steel to solidify rapidly. Later, the steel is scraped off by the limiting ring 137.

[0045] When the drill bit 127 has been drilling for a long time and is being maintained and repaired, a new drill bit 127 is connected to the inside of the limiting sleeve 121, and the position of the drill bit 127 is limited by the support strip 126. At this time, the swing arm plate 123 is swung and the shorter end of the swing arm plate 123 is used to press down on the surface of the extrusion plate 125, so that the extrusion plate 125 is tightly attached to the outer surface of the drill bit 127. The rectangular shape of the support strip 126 and the extrusion plate 125 is used to limit the position of the drill bit 127.

[0046] Obviously, the above embodiments are merely illustrative examples for clarity and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
