Description

Technical Field

[0001] This utility model relates to the technical field of blast furnace metallurgical equipment, and in particular to a cover-moving device. Background Technology

[0002] Currently, with the development of blast furnace metallurgical technology, the blast furnace tapping system is constantly being optimized and improved. The pressure inside the blast furnace is continuously increasing, and the amount of iron tapped is also increasing. This results in significant splashing of molten iron during tapping. To adapt to the increasingly stringent environmental protection situation, improve the working environment in front of the blast furnace, and reduce damage from heat radiation to the tapping machine, mud gun, and other equipment, the cover-moving machine has been developed. The cover-moving machine is placed over the iron trough after the tapping machine has finished its operation and returned to its original position, preventing smoke and slag generated during tapping from splashing everywhere. It also allows production personnel to approach the furnace door to clean the tapping opening when tapping is about to end, thus protecting the tapping equipment in front of the furnace. The cover-moving machine needs to be removed before tapping to allow the tapping machine to operate, and it also needs to be removed after tapping to allow the mud gun to be plugged. However, due to the structure and material of the cover, it is quite heavy. Repeated use in high-temperature areas can significantly reduce the service life of the cover-moving machine, especially when the cover is raised to its highest position and held for a long time, making it prone to damage.

[0003] Therefore, it is necessary to propose a cover-moving device to at least partially solve the problems existing in the prior art. Utility Model Content

[0004] The present invention aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, this utility model provides a cover-moving device.

[0006] In view of this, a cover-moving device is proposed according to an embodiment of this application, comprising:

[0007] Main body;

[0008] A movable part is provided on the main body and is used to move the main body.

[0009] An adjustment part is provided on the main body and is used to connect to the cover, and the distance between the cover and the iron groove is adjusted by the adjustment part.

[0010] When the adjustment unit raises the cover to its maximum stroke, the adjustment unit is in a self-locking state.

[0011] In one feasible implementation, the moving part includes:

[0012] The walking wheels are provided on the side of the main body that is away from the cover.

[0013] The first drive assembly is disposed in the main body and is used to provide power for the movement of the walking wheels.

[0014] In one feasible implementation, the moving part further includes:

[0015] A track is provided on the side of the main body that is away from the cover, and the wheels move along the track.

[0016] In one feasible implementation, the first driving component includes:

[0017] The first body is located at one end of the aforementioned main body;

[0018] The first hydraulic cylinder has one end connected to the first base body and the other end used to press against the structural component, which is arranged opposite to the first base body.

[0019] In one feasible implementation, the adjustment unit includes:

[0020] The second drive component is disposed in the aforementioned main body section;

[0021] The swing arm is rotatably connected to the main body, with its first end connected to the cover and its second end connected to the second drive assembly via a connecting component.

[0022] When the second drive component drives the swing arm to swing and lift the cover to its maximum stroke, the connecting component is in the self-locking state.

[0023] In one feasible implementation, the connection component includes:

[0024] A connecting plate, one end of which is rotatably connected to the second end via a first rotating shaft;

[0025] The connecting rod has one end of the connecting plate rotatably connected to one end of the connecting rod via a second rotating shaft, the other end of the connecting rod rotatably connected to the second drive assembly via a third rotating shaft, and the middle part of the connecting rod rotatably connected to the main body via a fourth rotating shaft.

[0026] When the second drive assembly drives the swing arm to lift to the maximum stroke, the connecting plate is in a vertical state, and the vertical lines of the first rotating shaft, the second rotating shaft, and the fourth rotating shaft coincide, and the connecting assembly is in a self-locking state.

[0027] In one feasible implementation, the adjustment unit further includes:

[0028] A baffle is provided on the main body to restrict the position of the connecting plate.

[0029] In one feasible implementation, the second driving component includes:

[0030] The second body is located in the aforementioned main body;

[0031] The second hydraulic cylinder has one end rotatably connected to the second base body, and the other end rotatably connected to the other end of the connecting rod via the third rotating shaft.

[0032] In one feasible embodiment, the above-mentioned cover-removing device further includes:

[0033] A lifting ring is provided at the first end, and the lifting lug is used to connect to the cover via a pin.

[0034] In one feasible implementation, the moving part is used to perform linear motion, and the moving distance of the moving part is greater than or equal to 3600mm.

[0035] Compared with the prior art, this utility model has at least the following beneficial effects: The cover-moving device provided in this application embodiment is provided with a main body, a moving part, and an adjusting part. The moving part and the adjusting part are both located on the main body. The moving part can move the main body and the adjusting part on the main body to a designated position to move closer to or further away from the iron trough. The cover is installed on the adjusting part, thereby adjusting the distance between the cover and the iron trough. After the iron tapping machine has finished its operation and returned to its original position, the cover is adjusted to cover the iron trough, preventing smoke and slag generated during tapping from splashing everywhere. Simultaneously, it allows production personnel to approach the furnace door to clean slag from the tapping opening when tapping is about to end. After tapping is completed, the cover is removed from the iron trough by the adjusting part, allowing the mud gun to be plugged. When the adjusting part lifts the cover to its maximum stroke in the direction away from the iron trench, the adjusting part is in a self-locking state. This maintains the position of the cover through the adjusting part's own structure, reduces the continuous pulling force provided by the adjusting part to the cover, reduces wear on the adjusting part, extends the service life of the adjusting part, reduces the frequency of accidents during use of the cover-moving device, and improves reliability.

Detailed Implementation

[0042] Exemplary embodiments of the present application will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this application will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0043] like Figures 1 to 3 As shown, according to an embodiment of this application, a cover-moving device 100 is proposed, including: a main body 110; a moving part 120 disposed on the main body 110 for moving the main body 110; and an adjusting part 130 disposed on the main body 110 for connecting to the cover body, thereby adjusting the distance between the cover body and the iron groove; wherein, when the adjusting part 130 lifts the cover body to its maximum stroke, the adjusting part 130 is in a self-locking state.

[0044] It is understood that this utility model has at least the following beneficial effects: The cover-moving device 100 provided in this application embodiment is provided with a main body 110, a moving part 120, and an adjusting part 130. The moving part 120 and the adjusting part 130 are both located on the main body 110. The moving part 120 can move the main body 110 and the adjusting part 130 on the main body 110 to a designated position to move closer to or further away from the iron trough. The cover is installed on the adjusting part 130, thereby adjusting the distance between the cover and the iron trough. After the iron tapping machine has finished its operation and returned to its original position, the cover is adjusted to cover the iron trough, preventing smoke and slag generated during tapping from splashing everywhere. Simultaneously, it allows production personnel to approach the furnace door to clean the tapping opening when tapping is about to end. After tapping is completed, the cover is removed from the iron trough by the adjusting part 130, allowing the mud gun to be plugged. When the adjusting part 130 lifts the cover to move away from the iron trench to its maximum stroke, the adjusting part 130 is in a self-locking state. This maintains the position of the cover through the structure of the adjusting part 130 itself, reduces the continuous pulling force provided by the adjusting part 130 to the cover, reduces the wear of the adjusting part 130, extends the service life of the adjusting part 130, reduces the frequency of accidents during use of the cover moving device 100, and improves reliability.

[0045] For example, the main body 110 may be provided with a high-temperature resistant coating on the side facing the iron trench to ensure that the cover-moving device 100 can operate stably in a high-temperature environment and improve reliability.

[0046] In some examples, such as Figures 1 to 3 As shown, the moving part 120 includes: a walking wheel 121 disposed on the side of the main body 110 facing away from the cover; and a first drive assembly 122 disposed on the main body 110 for providing power for the movement of the walking wheel 121.

[0047] It is understood that the moving part 120 is provided with a traveling wheel 121 and a first drive assembly 122. The traveling wheel 121 may be located on the side of the main body 110 opposite to the cover, i.e. Figure 1 The top of the indicated direction is used to move the main body 110 by the rolling of the walking wheels 121. The walking wheels 121 are powered by the first drive assembly 122, thereby reducing human intervention and realizing automated movement.

[0048] In some examples, the moving part 120 further includes a track disposed on the side of the main body 110 facing away from the cover, and the traveling wheel 121 moves along the track.

[0049] It is understandable that the moving part 120 may also be provided with a track. Specifically, the track may be provided on the side of the main body 110 opposite to the cover, i.e. Figure 1 At the top in the indicated direction, the traveling wheel 121 can move along the track. Through the guiding effect of the track, the traveling wheel 121 drives the main body 110 to move in a straight line.

[0050] In some examples, such as Figures 1 to 3 As shown, the first drive assembly 122 includes: a first seat 1221 disposed at one end of the main body 110; and a first hydraulic cylinder 1222, one end of which is connected to the first seat 1221 and the other end is used to press against the structural member, wherein the structural member and the first seat 1221 are disposed opposite to each other.

[0051] It is understood that the first drive assembly 122 may include a first base 1221 and a first hydraulic cylinder 1222. The first base 1221 may be located at the end of the main body 110 furthest from the cover. One end of the first hydraulic cylinder 1222 is connected to the first base 1221, and a structural member is provided along the extension direction of the first hydraulic cylinder 1222. The structural member and the first base 1221 are arranged opposite each other so that when the first hydraulic cylinder 1222 extends, it can press against the structural member, and the force will drive the traveling wheel 121 to roll, thereby moving the main body 110 as a whole. For example, the structural member may be a steel structural member. The hydraulic structure ensures that the cover-moving device 100 can stably move a relatively heavy cover.

[0052] In some examples, such as Figures 1 to 3 As shown, the adjustment unit 130 includes: a second drive assembly 131 disposed on the main body 110; a swing arm 132, the middle part of which is rotatably connected to the main body 110, the first end of which is connected to the cover, and the second end of which is connected to the second drive assembly 131 via a connecting assembly 133; wherein, when the second drive assembly 131 drives the swing arm 132 to swing and lift the cover to its maximum stroke, the connecting assembly 133 is in the self-locking state.

[0053] It is understood that the adjustment unit 130 may be provided with a second drive assembly 131 and a swing arm 132. The second drive assembly 131 may be located in the main body 110, providing a swinging force to the swing arm 132, allowing the swing arm 132 to swing the cover towards or away from the iron groove. Specifically, the middle part of the swing arm 132 can be rotatably connected to the main body 110 via a pivot, thus swinging around the pivot as the swing center to ensure stable swinging. The first end of the swing arm 132 is used to connect to the cover, and the second end of the swing arm 132 can be connected to the second drive assembly 131 via a connecting assembly 133. When the second drive assembly 131 drives the swing arm 132 to swing the cover away from the iron trench to its maximum stroke, the connecting assembly 133 is in a self-locking state to prevent the swing arm 132 from moving the cover back towards the iron trench due to the weight of the cover, thus avoiding a safety accident. In addition, the self-locking structure of the connecting assembly 133 maintains the position of the cover, reduces the operation of the adjusting part 130 to provide continuous tension to the cover, reduces the wear of the adjusting part 130, extends the service life of the adjusting part 130, reduces the frequency of accidents during use of the cover moving device 100, and improves reliability.

[0054] In some examples, such as Figures 1 to 3 As shown, the connecting assembly 133 includes: a connecting plate 1331, one end of which is rotatably connected to the second end via a first rotating shaft a; and a connecting rod 1332, the other end of which is rotatably connected to one end of which via a second rotating shaft b, the other end of which is rotatably connected to the second driving assembly 131 via a third rotating shaft c, and the middle part of which is rotatably connected to the main body 110 via a fourth rotating shaft d. When the second driving assembly 131 drives the swing arm 132 to its maximum stroke, the connecting plate 1331 is in a vertical state, and the vertical lines of the first rotating shaft a, the second rotating shaft b, and the fourth rotating shaft d coincide, and the connecting assembly 133 is in a self-locking state.

[0055] It is understood that the connecting assembly 133 may be provided with a connecting plate 1331 and a connecting rod 1332. One end of the connecting plate 1331 is rotatably connected to the second end of the swing arm 132 via a first rotating shaft a. The other end of the connecting plate 1331 is rotatably connected to one end of the connecting rod 1332 via a second rotating shaft b. The other end of the connecting rod 1332 is rotatably connected to the second drive assembly 131 via a third rotating shaft c. The middle part of the connecting rod 1332 is rotatably connected to the main body 110 via a fourth rotating shaft d. With this configuration, the second drive assembly 131 can drive the connecting rod 1332 to rotate, thereby driving the connecting plate 1331 to rotate, and in turn, the connecting plate 1331 drives the swing arm 132 to swing. When the swing arm 132 is raised to its maximum stroke, the connecting plate 1331 is in a vertical state, and the vertical lines of the first rotating shaft a, the second rotating shaft b, and the fourth rotating shaft d coincide, and the connecting assembly 133 is in a self-locking state.

[0056] In some examples, such as Figure 1 As shown, the adjustment part 130 further includes a baffle 140, which is disposed on the main body part 110 and is used to limit the position of the connecting plate 1331.

[0057] It is understandable that the adjustment part 130 may also be provided with a baffle 140. Specifically, the baffle 140 is provided on the main body part 110 and fits against the connecting rod 1332. When the connecting plate 1331 is in a vertical position, the baffle 140 presses against the connecting plate 1331 to limit the connecting plate 1331 to maintain a self-locking position, prevent the swing arm 132 from continuing to rise and causing damage, improve reliability, and increase the structural strength of the connecting rod 1332.

[0058] In some examples, such as Figure 1 and Figure 2 As shown, the second drive assembly 131 includes: a second seat 1311 disposed on the main body 110; and a second hydraulic cylinder 1312, one end of which is rotatably connected to the second seat 1311, and the other end of which is rotatably connected to the other end of the connecting rod 1332 via the third rotating shaft c.

[0059] Understandably, the second drive assembly 131 may include a second seat 1311 and a second hydraulic cylinder 1312. The second seat 1311 is located on the main body 110. One end of the second hydraulic cylinder 1312 is rotatably connected to the second seat 1311, and the other end of the second hydraulic cylinder 1312 is rotatably connected to the other end of the connecting rod 1332 via a third rotating shaft c. Through the extension, retraction, and rotation of the second hydraulic cylinder 1312, the connecting rod 1332 and the connecting plate 1331 are rotated, thereby causing the swing arm 132 to swing. This hydraulic structure ensures that the cover-moving device 100 can stably move a heavy cover, improving reliability.

[0060] In some examples, such as Figure 1 As shown, the above-mentioned cover-moving device 100 further includes: a lifting ring 150, which is disposed at the first end, and the lifting lug is used to connect to the cover body via a pin.

[0061] It is understandable that the first end of the swing arm 132 can be provided with a lifting ring 150, and the cover can be connected to the lifting lug by a pin, so that the cover can be moved by the cover moving device 100, making the installation simple and convenient.

[0062] In some examples, the moving part 120 is used to perform linear motion, and the moving distance of the moving part 120 is greater than or equal to 3600 mm.

[0063] It is understandable that the moving part 120 can move linearly, and the moving distance of the moving part 120 is greater than or equal to 3600mm, so as to be applicable to most situations and improve applicability.
