Description

Technical Field

[0001] The utility model relates to the technical field of steel smelting, in particular to a drainage sand adding device. Background Art

[0002] With the continuous development of intelligent manufacturing technology, traditional manufacturing has gradually changed from manual operation to intelligent and even unmanned operation. In the iron and steel metallurgical industry, there are many scenarios where robots are used to clamp supporting tools to replace manual operations. For example, robots are used to perform various operations in the hot repair process of the ladle, and robots are used to replace manual temperature measurement and sampling of molten steel. However, robots cannot replace all manual operations in the metallurgical workshop for the time being. For example, the operation of adding drainage sand to the ladle is still manually operated by an electric hoist to drive the sand adding bucket from the upper water inlet to the inside of the ladle for filling. Since the temperature measurement and sampling robot needs to be extended from the upper water inlet into the ladle to obtain molten steel, when the drainage sand is manually added, the temperature measurement and sampling robot may accidentally injure the sand adding worker during operation, which poses a certain safety hazard. If the sand adding operation is performed after the temperature measurement and sampling robot has completed the operation, it will affect the overall time and work efficiency of the metallurgical operation. In view of this, the utility model is proposed. Utility Model Content

[0024] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0025] See also Figure 1 , Figure 1 It is a three-dimensional structural schematic diagram of the drainage sand adding device provided by the embodiment of the utility model. The drainage sand adding device 1 comprises a support frame 11, a sand adding box 12, a sand adding hopper 13 and a jack 14. The support frame 11 is fixed to one side of the upper water inlet of the ladle. The sand adding box 12 is used to place the drainage sand bag. The sand adding box 12 is installed on the support frame 11 and can move linearly along the support frame 11. The jack 14 is fixed to the upper position of the upper water inlet of the ladle and is connected to the sand adding hopper 13 to lift the sand adding hopper 13 from the upper water inlet of the ladle into the interior of the ladle. The sand adding box 12 can drive the sand adding bag to move to the sand adding hopper 13 for adding sand.

[0026] The support frame 11 is fixed to one side of the ladle upper water inlet to carry the sand box 12, and then the position of the sand box 12 is adjusted when the sand box 12 moves linearly along the support frame 11, so as to Figure 1With the orientation as a reference, when the temperature measuring sampling robot clamps the sampling rod and extends it from the ladle upper water inlet into the ladle for temperature measuring sampling operation, the sand adding box 12 can be moved to the first position at the far left position, so that the sand adding box 12 and the ladle upper water inlet are misaligned, so that the robot can perform temperature measuring sampling operation. At the same time, the worker can put the drainage sand bag into the sand adding box 12 for preparation before adding sand. When the temperature measuring sampling robot completes the temperature measuring sampling operation, the sand adding box 12 can be moved to the second position at the far right position. At this time, the sand adding box 12 is located above the ladle upper water inlet. After the sand adding hopper 13 is lifted down by the jack 14 and extends into the ladle from the ladle upper water inlet, the worker can cut the sand adding bag in the sand adding box 12 to allow the drainage sand to enter the sand adding box 12 and slide into the sand adding hopper 13, thereby realizing the sand adding operation to the ladle.

[0027] Since the prior art mainly manually adds drainage sand into the sand adding hopper 13 during the sand adding operation, it is necessary to wait for the temperature measuring and sampling robot to complete the temperature measuring and sampling before the workers can add sand. Moreover, it takes a certain amount of time to put the drainage sand bag into the sand adding hopper 13 and then break the sand bag when adding sand. If the temperature measuring and sampling operation and the sand adding operation are carried out at the same time, the temperature measuring and sampling robot may collide with the sand adding worker during the operation, affecting the personal safety of the sand adding worker.

[0028] Compared with the prior art, the drainage sand adding device 1 of the present scheme can move the sand adding box 12 to the first position, so that the sand adding box 12 and the ladle upper water inlet are misaligned to avoid affecting the normal operation of the temperature measuring sampling robot. At the same time, it can also provide a sand adding worker with a sand bag to put the sand adding bag into the sand adding box 12 to carry out preparation work before sand adding. After the temperature measuring sampling robot completes the temperature measuring sampling operation, the sand adding box 12 is moved from the support frame 11 to the second position, and the crane 14 is controlled to lift the sand adding bucket 13 down. By breaking the sand adding bag in the sand adding box 12, the drainage sand can slide through the sand adding box 12 into the sand adding bucket 13, thereby realizing the drainage sand filling operation of the ladle, reducing the safety risk of the sand adding worker during operation, and improving the drainage sand adding efficiency.

[0029] See also Figure 2 , Figure 2 The figure is a three-dimensional structural diagram of a sand adding box in a drainage sand adding device provided in an embodiment of the utility model. In the embodiment of the utility model, the sand adding box 12 includes a box body 121, a bracket 122 and a wheel 123, the bracket 122 is connected to the bottom surface of the box body 121, the wheel 123 is installed on the bracket 122, and the box body 121 moves linearly on the support frame 11 through the wheel 123.

[0030] By using the bracket 122 to support the box body 121, the height of the box body 121 is increased, so that when the sand adding hopper 13 descends and penetrates into the water inlet of the ladle, the position of the box body 121 is higher than the position of the sand adding hopper 13 to form a height difference, so that the drainage sand in the box body 121 can flow into the sand adding hopper 13, thereby realizing the filling of the drainage sand for the ladle. By installing the wheels 123 on the bracket 122, the wheels 123 roll on the support frame 11 when the box body 121 moves relative to the support frame 11, thereby reducing the friction and resistance when the box body 121 moves, and facilitating the linear movement of the sand adding box 12 relative to the support frame 11.

[0031] It can be understood that the connection method between the bracket 122 and the bottom surface of the box body 121 includes any one of welding connection, bolt connection, hinge connection, contact connection and a combination thereof. When the bracket 122 and the bottom surface of the box body 121 are welded, the structural stability between the bracket 122 and the box body 121 can be made stronger, and the service life of the sand adding box 12 is improved. When bolt connection is adopted, the bracket 122 and the box body 121 can be detachably connected, so that it is convenient to flexibly disassemble and assemble when the bracket 122 or the box body 121 needs to be repaired or replaced. When a combination of hinge connection and contact connection is adopted, the box body 121 can be rotated around the bracket 122, so that the drainage sand in the box body 121 can be poured into the sand adding hopper 13, and the phenomenon of drainage sand hanging on the wall in the box body 121 is reduced.

[0032] In the embodiment of the present utility model, the box body 121 includes a sand inlet 1211 with an open top and a sand outlet 1212 extending to one side of the sand hopper 13 , and the size of the sand outlet 1212 is smaller than that of the sand inlet 1211 .

[0033] By opening a sand inlet 1211 at the top of the box body 121 and a sand outlet 1212 on one side of the box body 121 extending to the sand adding hopper 13, it is convenient for the sand adding worker to place the sand bag in the sand inlet 1211, and by cutting the sand bag, the drainage sand in the sand bag flows out and flows along the direction of the sand outlet 1212, and finally flows into the sand adding hopper 13, thereby realizing the drainage sand filling operation for the ladle.

[0034] When performing drainage sand filling operations, by moving the sand adding box 12 to the first position, it is convenient for the sand adding worker to put the drainage sand bag into the sand inlet 1211. At this time, the sand adding box 12 is misaligned with the ladle water inlet, so the temperature measuring sampling robot will not affect the personal safety of the sand adding worker. After the temperature measuring sampling robot completes the temperature measuring sampling operation, by moving the sand adding box 12 to the second position, and at the same time controlling the crane 14 to lift the sand adding hopper 13 down and extend it into the ladle water inlet, the sand adding bag is broken to allow the drainage sand in the drainage sand bag to flow into the sand adding hopper 13 through the sand outlet 1212. Compared with the sand adding method in the prior art, the drainage sand adding device 1 of this scheme can improve the work efficiency of the sand adding operation.

[0035] It can be understood that the size of the sand inlet 1211 is larger than the size of the sand bag, so that the workers can put the sand bag into the box 121 through the sand inlet 1211 for storage, and the size of the sand outlet 1212 is smaller than the size of the sand hopper 13, so that the drainage sand flowing out of the sand outlet 1212 can flow into the sand hopper 13, thereby limiting the flow speed of the drainage sand and avoiding blockage of the sand hopper 13.

[0036] See also Figure 2 In the embodiment of the utility model, the bottom surface of the box body 121 is an inclined surface inclined downward toward the side of the sand adding hopper 13. The bottom surface of the box body 121 is set as an inclined surface, so that the drainage sand in the box body 121 can flow into the sand adding hopper 13 under the action of gravity. After the sand adding worker completes the bag breaking operation, the automatic filling effect of the drainage sand can be achieved. There is no need for the sand adding worker to stir the drainage sand in the box body 121, saving some manpower.

[0037] See also Figure 3 , Figure 3 It is a three-dimensional structural diagram of a sand adding box in a drainage sand adding device provided by another embodiment of the utility model. In the embodiment of the utility model, the bottom surface of the box body 121 is a plane, and there are four brackets 122 distributed around the bottom surface of the box body 121. The two brackets 122 close to the sand adding hopper 13 are hingedly connected to the bottom surface of the box body 121, and the two brackets 122 away from the sand adding hopper 13 support the bottom surface of the box body 121.

[0038] Since the bottom surface of the box body 121 is an inclined surface, the sand-filled bags placed in the box body 121 will slide toward the sand outlet 1212, causing the sand outlet 1212 to be blocked. When breaking the bags, the sand-filled bags need to be pulled up and then broken. The bag breaking process is relatively laborious. In the present embodiment, the bottom surface of the box body 121 is a flat surface, thereby preventing the sand-filled bags placed in the box body 121 from moving toward the sand outlet 1212. At the same time, the connection method between the box body 121 and the bracket 122 is improved. The side of the box body 121 close to the sand adding hopper 13 is hingedly connected to the bracket 122, and the side of the box body 121 away from the sand adding hopper 13 is contact-connected with the bracket 122. Therefore, after the sand adding worker completes the bag breaking operation, by lifting the box body 121, the box body 121 can be rotated around the bracket 122 to allow the drainage sand in the box body 121 to flow into the sand adding hopper 13, thereby completing the sand adding operation to the ladle.

[0039] It can be understood that a hinged ear plate 1213 is provided on the side of the box body 121 close to the sand adding bucket 13, and a hinge shaft 1221 is provided on the bracket 122 which is aligned with the hinged ear plate 1213. The box body 121 and the bracket 122 are hinged through the connection between the hinged ear plate 1213 and the hinge shaft 1221. Since the side of the box body 121 away from the sand adding bucket 13 is in contact connection with the bracket 122, the sand adding worker can lift the side of the box body 121 in contact connection with the bracket 122, so that the box body 121 can rotate around the hinge shaft 1221, and then pour the drainage sand in the box body 121 into the sand adding bucket 13.

[0040] See also Figure 4 , Figure 4 1 is a three-dimensional structural diagram of a support frame in a drainage sand adding device provided in an embodiment of the utility model. In the embodiment of the utility model, the support frame 11 includes a frame body 111 and a guide rail 112, and the guide rail 112 is fixed to the surface of the frame body 111 for the sand adding box 12 to move linearly along the guide rail 112.

[0041] By fixing the guide rail 112 on the frame 111, the wheels 123 on the sand box 12 can move linearly under the limit of the guide rail 112, so as to ensure that the path of each movement of the sand box 12 is the same. Among them, the frame 111 includes four support legs and a support plate, and the four support frames 11 are fixedly connected to the four sides of the support plate to support the support plate. The guide rail 112 includes two symmetrically arranged wheels 123 on the sand box 12, and the two sets of guide rails 112 and the two sets of wheels 123 are arranged in a pair, so that the sand box 12 can move linearly along the guide rail 112.

[0042] In an embodiment of the utility model, limiting plates 113 for limiting the sand box 12 from moving out of bounds are provided on both sides of the guide rail 112. By providing the limiting plates 113 on both sides of the guide rail 112, the movement of the sand box 12 is limited by the limiting plates 113 when the sand box 12 moves along the guide rail 112, thereby preventing the sand box 12 from moving out of bounds from both sides of the guide rail 112 and causing damage to the sand box 12.

[0043] The guide rail 112 is a U-shaped steel shape, and the wheel 123 is placed in the guide rail 112 for movement, so as to further enhance the stability of the sand box 12 when performing linear motion, and at the same time prevent the missed drainage sand from entering the guide rail 112 and affecting the movement of the sand box 12.

[0044] In the embodiment of the present invention, a driving member (not shown) connected to the sand box 12 is disposed on the frame 111 to drive the sand box 12 to move linearly along the guide rail 112 .

[0045] By installing a driving component on the frame 111 and connecting the driving component to the sand adding box 12, the box 121 is driven by the driving component to move along the guide rail 112, and the manual pushing of the sand adding box 12 is replaced by mechanical driving of the sand adding box 12, which saves some manpower. The driving component includes any one of a linear motor, an oil cylinder, and a servo electric cylinder. As a preferred embodiment, the driving component adopts a servo electric cylinder, which is installed on the surface of the frame 111. The output end of the servo electric cylinder is connected to the side of the sand adding box 12. The effect of linear movement of the sand adding box 12 along the guide rail 112 is achieved by driving the extension and retraction of the servo electric cylinder, thereby enhancing the intelligence of the drainage sand adding device 1.

[0046] In the embodiment of the utility model, the sand adding hopper 13 is funnel-shaped and has a sand guide pipe 131 connected to the ladle outlet at the bottom, and the lifting device 14 includes any one of a crane and an electric hoist.

[0047] By arranging a sand guide pipe 131 at the bottom of the sand adding hopper 13, after the sand adding hopper 13 descends, the sand guide pipe 131 can extend into the upper water inlet of the ladle. As the sand adding hopper 13 continues to descend, the sand guide pipe 131 can reach the lower water outlet of the ladle. At this time, by pouring the drainage sand in the sand adding box 12 into the sand adding hopper 13, the drainage sand of the ladle can be bent and sunk, and the added drainage sand can directly reach the lower water outlet of the ladle.

[0048] The hoist 14 is set to be any one of a crane and an electric hoist, and the sand adding bucket 13 is connected to the hoist 14 through a chain, so that the sand adding bucket 13 is lifted and lowered under the action of the hoist 14, so that the sand adding bucket 13 is extended into the inside of the ladle or taken out from the inside of the ladle.

[0049] It should be noted that since the sand guide tube 131 and the chain are both slender parts, Figure 1The chain and the sand guide tube 131 are omitted in the figure to clearly show the structure of other components in the figure.

[0050] In an embodiment of the present utility model, the sand adding device further comprises a guardrail 15, the guardrail 15 comprises a guard frame 151 and a guard net 152, the guard frame 151 is fixed on both sides of the support frame 11, and the guard net 152 is located above the sand adding box 12 and is fixedly connected to the guard frames 151 on both sides.

[0051] By fixing the protective frame 151 on both sides of the support frame 11 and fixing the protective net 152 between the protective frames 151 on both sides, the activities of sand adding workers during sand adding operations are restricted, thereby preventing the sand adding workers from entering the operating range of the robot and causing safety accidents.

[0052] In the present utility model, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may mean that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. Moreover, a first feature being "above", "above" or "above" a second feature may mean that the first feature is directly above or obliquely above the second feature, or simply means that the first feature is higher in level than the second feature. A first feature being "below", "below" or "below" a second feature may mean that the first feature is directly below or obliquely below the second feature, or simply means that the first feature is lower in level than the second feature.

[0053] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, including the combination of various specific technical features in any appropriate manner.
