Description

Technical Field

[0001] The utility model relates to the technical field of steelmaking, in particular to a steel billet turning device. Background Art

[0002] When hot billets are transported from the steelmaking process to the rolling mill, uneven cooling can cause multiple billets to bend to varying degrees, with the two outer billets being particularly severely bent. The billets are hoisted by an overhead crane onto a walking gantry, then conveyed via a steel shifter and a furnace roller conveyor into the heating furnace. Bent billets can exhibit varying degrees of curvature upon entry, with some exhibiting outward or inward curvature. These curved billets can severely impact the equipment, striking the conveyor rollers, furnace door frame, furnace walls, and cantilever rollers, posing a serious threat to the safe operation of the heating furnace.

[0003] The existing solution is to use manual steel turning. During operation, the employee operates the steel turning electric hoist to make the steel turning fixture fall, and then manually clamp the fixture from the side of the billet, and then raise the electric hoist to turn the billet 90°. If the billet is not turned to the standard posture for entering the furnace (the curved side is facing up), the above operation needs to be repeated again until the billet is turned to the appropriate posture. The small bar production line has a fast pace and high output. The number of billets rolled in one shift can reach 900, of which the proportion of billets that need to be turned over can reach 40%. Especially in the summer, the environment outside the heating furnace is harsh, and the labor intensity of the employees is huge. At the same time, it is very easy for the steel turning fixture to slip and rebound to the operator during use. There is also the risk of the operator misoperating the roller during steel turning, the person standing in an improper position, or the steel turning mechanism being hit and involved, which greatly threatens the life safety of the operator. Utility Model Content

[0004] The utility model aims to provide a steel billet turning device, which is simple to operate and greatly reduces the manual labor intensity and the safety risks in the process of manual steel turning.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a steel billet turning device, which includes a V-shaped groove arranged at the unloading end of the loading platform, a steel turning claw connected to the end of the moving beam of the loading platform, and a steel shifting machine arranged between the loading platform and the roller. The moving beam of the loading platform is configured to drive the steel turning claw to perform a circular motion from top to bottom in the vertical direction to lift and lift the steel billet that falls into the V-shaped groove and replace it in the V-shaped groove. The steel shifting machine is configured to shift the steel billet that is in a qualified state after being turned in the V-shaped groove onto the roller.

[0006] Preferably, the V-shaped groove is a 45° groove.

[0007] Preferably, the portion of the steel turning claw that contacts the steel billet is in a horizontal state.

[0008] Preferably, the lifting of the steel turning claw is arranged to be synchronized with the stepping of the loading platform.

[0009] Preferably, the end of the turning claw is formed with an upward hook.

[0010] Preferably, a blocker is provided near the unloading end of the loading platform, and the blocker is driven by a cylinder to move up and down to block the steel billet or release the steel billet closest to the unloading end into the V-groove.

[0011] Preferably, the loading platform, steel digging machine, cylinder and roller are all electrically connected to the controller in the control room so that the operator can remotely control the opening, pausing and closing of the loading platform, steel digging machine, cylinder and roller.

[0012] According to the above technical solution, the utility model converts the steel turning process from the original steel turning on the roller to steel turning on the platform V-groove. Specifically, the movable beam of the loading platform is configured to be able to drive the steel turning claw to make a circular motion from top to bottom in the vertical direction to lift and lift the steel billet that falls into the V-groove and replace it in the V-groove, and the steel shifting machine is configured to shift the steel billet in the V-groove that is in a qualified state after being turned over onto the roller. In this way, when the steel billet enters the furnace from the loading platform, it will always pass through the V-groove. When the loading platform steps forward, it will drive the steel turning claw to rise, and cooperate with the V-groove to complete the steel turning work. The whole process can simultaneously carry out the steel merging operation while the steel turning operation is being carried out, and the two processes can be combined into one, killing two birds with one stone, and the labor intensity of the personnel is greatly reduced, eliminating the safety risks in the process of manual steel turning.

[0020] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.

[0021] In the present invention, unless otherwise stated, directional words such as "up, down, horizontal, vertical" contained in a term merely represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.

[0022] See also Figure 1 The utility model provides a steel billet turning device, which includes a V-shaped groove 3 arranged at the unloading end of a loading platform 1, a steel turning claw 2 connected to the end of a movable beam of the loading platform 1, and a steel shifting machine 5 arranged between the loading platform 1 and a roller 6. The movable beam of the loading platform 1 is configured to drive the steel turning claw 2 to perform a circular motion from top to bottom in the vertical direction to lift and lift the steel billet 4 that has fallen into the V-shaped groove 3 and replace it in the V-shaped groove 3. The steel shifting machine 5 is configured to shift the steel billet 4 in the V-shaped groove 3 that is in a qualified state after being turned over onto the roller 6.

[0023] Through the above technical solution, the steel turning process is converted from the original steel turning on the roller to steel turning on the platform V-groove. Specifically, the movable beam of the loading platform 1 is set to be able to drive the steel turning claw 2 to make a circular motion from top to bottom in the vertical direction to lift the steel billet 4 that falls into the V-groove 3 and replace it in the V-groove 3, and the steel shifting machine 5 is set to be able to shift the steel billet 4 in the V-groove 3 that is in a qualified state after being turned over onto the roller 6. In this way, when the steel billet 4 enters the furnace from the loading platform 1, it will always pass through the V-groove 3. When the loading platform 1 steps forward, it will drive the steel turning claw 2 to rise, and cooperate with the V-groove 3 to complete the steel turning work. The whole process can simultaneously carry out the steel merging operation when the steel turning operation is being carried out, and the two processes can be combined into one, killing two birds with one stone, and the labor intensity of the personnel is greatly reduced, eliminating the safety risks in the process of manual steel turning.

[0024] In this embodiment, in order to adjust the steel billet 4 in an erroneous state to a qualified state with the least number of flips as possible, preferably, the V-groove 3 is a 45° groove. With a 45° V-groove 3, when the steel billet 4 enters the V-groove 3 from the loading platform 1, it will always be in a 45° inclined state. When the loading platform 1 continues to step, the steel turning claw 2 performs a circular motion from top to bottom in the vertical direction, first contacting the steel billet 4 in a 45° inclined state, lifting it from the V-groove 3 and lifting it. During the lifting process, the steel billet 4 will flip 45° to a flat state under the action of its own gravity. At this time, the steel turning claw 2 will rise to the top and then begin to descend. After continuing to descend, it will put the flat billet 4 back into the V-groove 3. Due to the V-shaped structure of the V-groove 3, the steel billet 4 will still be in a 45° inclined state, thus realizing the flipping of the steel billet 4. If the steel billet 4 has been flipped to a qualified state at this time, the steel flipping machine 5 can be turned on to flip it into the roller 6 for continued transportation. If it has not been flipped to a qualified state, the steel flipping operation of the steel flipping claw 2 needs to be continued until it reaches a qualified state and then the steel flipping machine 5 will flip it into the roller 6 for continued transportation.

[0025] When the above-mentioned steel turning claw 2 lifts and elevates the steel billet 4 from the V-groove 3, in order to enable the steel billet 4 to be smoothly adjusted to a flat state and to maintain the flat state, and to avoid it from flipping over and causing subsequent adjustment and flipping failure, preferably, the part of the steel turning claw 2 that contacts the steel billet 4 is in a horizontal state.

[0026] In this embodiment, in order to combine the steel turning operation and the steel joining operation into one process, killing two birds with one stone, it is preferred to set the lifting of the steel turning claw 2 to be synchronized with the stepping of the loading platform 1.

[0027] Furthermore, in order to prevent the billet 4 from sliding or even falling off the billet during the process of lifting the billet 4, thereby affecting the subsequent turning operation, the billet 4 is preferably provided with an upward hook at the end of the billet claw 2. This hook can effectively restrain the position of the billet 4, allowing the subsequent turning claw 2 to cooperate smoothly with the V-shaped groove 3, without affecting the turning operation due to the misalignment of the billet 4.

[0028] When the steel turning claw 2 is performing the steel turning operation, if the current steel billet 4 needs to be turned over multiple times to be adjusted to a qualified state, the subsequent steel billets 4 on the loading platform 1 need to be controlled to prevent them from falling into the V-groove 3 one after another when the current steel billet 4 has not been adjusted, causing confusion in the operation process at the site and making it difficult to continue turning the steel. Therefore, it is preferred that a blocker is provided near the unloading end of the loading platform 1, and the blocker is driven by a cylinder to move up and down to block the steel billet 4 or release the steel billet 4 closest to the unloading end into the V-groove 3.

[0029] In addition, in order to realize remote operation of the operator, further reduce the labor intensity when turning the steel and reduce the risks and hidden dangers of manual operation, preferably, the loading platform 1, the steel digging machine 5, the cylinder and the roller 6 are all electrically connected to the controller in the control room so that the operator can remotely control the opening, pausing and closing of the loading platform 1, the steel digging machine 5, the cylinder and the roller 6.

[0030] When using this billet turning device, in actual use, the overhead crane is turned on to lift the billet 4 to the loading platform 1. The loading platform 1 continuously steps to transport the billet 4 to the V-groove 3 in front of the loading platform 1. After the billet 4 is turned to a qualified state by the V-groove 3 and the turning claw 2, the billet on the V-groove 3 is transferred to the roller 6 by the steel shifting machine 5, and finally transported to the heating furnace. Among them, the billet 4 is always in a 45-degree inclined state in the V-groove 3. The turning claw 2 welded to the end of the moving beam of the loading platform 1 will lift the billet 4 in the V-groove 3 when the loading platform 1 moves. Under its own weight, the billet 4 will turn 45 degrees and lie flat. Every time the platform steps, the billet 4 will turn 45°. After continuous turning, it reaches the required billet state and is finally transported to the roller 6 by the steel shifting machine 5 for loading into the furnace. The entire steel turning process is smooth, simple, convenient and easy to operate, which perfectly solves the problem of difficulty in turning steel on small bars, and greatly solves the problem of high labor intensity and certain safety risks for workers when turning steel.

[0031] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.

[0032] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0033] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
