Description

Technical Field

[0001] The utility model belongs to the technical field of steel bar production, and mainly relates to a steel billet rejecting device. Background Art

[0002] Billets are semi-finished products obtained by casting molten steel from a steelmaking furnace. After exiting the furnace, billets are transported to the rolling mill via multiple rollers, where rolling begins. Adjacent rollers are spaced apart, ensuring that the billet's axis is parallel to the roller's forward motion. If the mill or subsequent equipment malfunctions, the billet's prolonged stay on the rollers can cause the billet's temperature to drop. This cooled billet cannot meet the requirements of normal rolling, requiring it to be removed from the rollers. The billet is nine meters long, and the rollers are approximately three meters long.

[0003] The conventional cleaning method is to use an anchor chain or sling in conjunction with the workshop's overhead crane to lift the steel billet off the roller table. During lifting, manual labor is required to approach the steel billet and hang the anchor chain or sling on the steel billet. However, the temperature of the steel billet coming out of the steelmaking furnace is too high, reaching 1000 degrees Celsius. Manual operation is extremely dangerous. In addition, manually hanging the anchor chain or sling on the steel billet and then lifting it with the overhead crane takes too long and has low efficiency. Utility Model Content

[0004] The utility model provides a steel billet rejecting device to solve the problems of high operation risk and low operation efficiency in the prior art.

[0005] In order to solve the above problems, the present invention adopts the following technical solutions:

[0006] A billet rejection device comprises a controller, multiple support frames, and multiple rejection plates; the multiple rejection plates are fixed on a hinged shaft, the multiple rejection plates are parallel front and back in the axial direction of the hinged shaft and are respectively located at the roller gap between two adjacent rollers, and the width of the rejection plate is smaller than the width of the roller gap; the support frame is located beside the roller and the multiple support frames are parallel in the front-to-back direction, the hinged shaft is rotatably assembled on the support frame and the hinged shaft is transmission-connected with multiple driving devices for driving its rotation; multiple receiving plates for collecting billets are provided at the discharge end of the rejection plate, and the multiple receiving plates are parallel in the front-to-back direction; the controller is controlled and connected to the driving device to control the action of the driving device to make the rejection plate flip upward until the billet slides onto the receiving plate when a failure occurs in the rolling mill or subsequent equipment.

[0007] Beneficial effects: When a failure occurs in the rolling mill or subsequent equipment, the controller controls the action of the driving device, and the driving device drives the articulated shaft to rotate. The articulated shaft drives multiple rejection plates to flip upward at the same time, and the rejection plates become an inclined surface. At the same time, the steel billets on the roller are lifted up by multiple rejection plates. During the lifting process, the steel billets slide down from the inclined surface to the receiving plate. The utility model does not require manual operation to approach the high-temperature steel billets, reducing the risk of manual operation, and does not require manual operation to hang anchor chains or slings on the steel billets and then lift them through the overhead crane, reducing operation time and improving operation efficiency.

[0008] Furthermore, a plurality of connecting rods are evenly spaced on the articulated shaft in the direction of roller conveying, and the connecting rods are hinged to the corresponding driving devices; a fixed seat corresponding to the driving device is provided on the side of the roller, and the driving device is hinged to the corresponding fixed seat.

[0009] Beneficial effects: the driving device drives the connecting rod to rotate, and at the same time the hinge shaft rotates and the reject plate rotates, and the structure is simple.

[0010] Furthermore, the driving device is a hydraulic cylinder, the piston rod end of the hydraulic cylinder is hinged to the corresponding connecting rod, and the fixed end of the hydraulic cylinder is hinged to the corresponding fixing seat.

[0011] Beneficial effects: The structure of the hydraulic cylinder is relatively simple, maintenance is convenient, and the failure rate is low.

[0012] Furthermore, each of the receiving plates has a guiding slope and a stopping surface, and the upper end of the guiding slope is located directly below the discharge end of the rejecting plate.

[0013] Beneficial effect: The upper end of the guide slope is located just below the discharge end of the reject plate, preventing the steel billet from falling between the receiving plate and the reject plate, and the stop surface prevents the steel billet from sliding out of the receiving plate due to the inertia of sliding down the guide slope.

[0014] Furthermore, a curved surface is provided between the guide inclined surface and the stop surface to connect the two.

[0015] Beneficial effect: The existence of the arc surface prevents the steel billet from sliding to the inner bend of the guide inclined surface and the stop surface due to inertia, causing collision damage.

[0016] Furthermore, the material receiving plate is an L-shaped structure.

[0017] Furthermore, support columns are respectively provided on the material receiving plate below the guiding inclined surface and the curved surface.

[0018] Beneficial effect: the support column supports the material splicing plate to ensure the stability of the material splicing plate.

[0019] Furthermore, the rejection plate is a channel steel.

[0020] Beneficial effects: The cross-sectional shape of the channel steel makes it have strong bending and torsion resistance, suitable for structural components that bear large loads, and the channel steel is easy to process and install. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] Example 1 of a steel billet removal device provided by the utility model:

[0029] like Figure 1 and Figure 2As shown, the billet rejection device includes a controller and a plurality of rejection plates 6. In this embodiment, six rollers 7 are provided, and the six rollers 7 form five roller gaps. Five rejection plates 6 are provided, and the five rejection plates 6 are respectively rotated and assembled in the corresponding roller gaps, and the width of the rejection plates 6 is smaller than the width of the roller gaps. The rejection plates 6 are made of channel steel. The cross-sectional shape of the channel steel makes it have strong bending and torsion resistance, which is suitable for structural components that bear large loads, and the channel steel is easy to process and install. Of course, the rejection plates 6 can also be made of steel with other structures, such as T-shaped steel. In other embodiments, the number of rejection plates 6 can be selected according to actual needs and is not limited to the five in this embodiment. It is only necessary to ensure that there are rejection plates 6 in the roller gaps.

[0030] In this embodiment, for the convenience of description, Figure 2 As shown, the length direction of the roller conveyor 7 is defined as the front-rear direction, the width direction is defined as the left-right direction, and the height direction is defined as the up-down direction.

[0031] like Figure 1 and Figure 2 As shown, six support frames 5 are arranged parallel and equidistantly in the front-to-back direction on the left side of the reject plate 6. A hinge shaft 8 extending in the front-to-back direction is provided between the six support frames 5. The hinge shaft 8 is rotatably mounted on the six support frames 5, and the reject plate 6 is fixed on the hinge shaft 8. The five reject plates 6 are arranged parallel and equidistantly in the front-to-back direction along the axis of the hinge shaft 8. Of course, in other embodiments, the number of support frames 5 can be selected according to actual needs and is not limited to the six in this embodiment.

[0032] like Figure 1 and Figure 2 As shown, the hinge shaft 8 is provided with three connecting rods 4 arranged at equal intervals in the front-to-back direction, and the connecting rods 4 are fixed to the hinge shaft 8. Three fixing seats 3 are also provided on the left side of the rejection plate 6, which are arranged at equal intervals in the front-to-back direction. The three fixing seats 3 are respectively hinged with hydraulic cylinders 2. The fixed ends of the three hydraulic cylinders 2 are respectively hinged to the corresponding fixing seats 3, and the piston rod ends of the hydraulic cylinders 2 are hinged to the end of the connecting rod 4 away from the rejection plate 6. The hydraulic cylinders 2 are connected to a controller, which controls the action of the hydraulic cylinders 2 to rotate the rejection plate 6 upward. Of course, in other embodiments, the number of fixing seats 3, connecting rods 4 and hydraulic cylinders 2 can be selected according to actual needs and is not limited to the three in this embodiment.

[0033] like Figure 1 and Figure 2As shown, the bottom of each reject plate 6 is provided with a receiving plate 1 for receiving the steel billet.

The receiving plates 1 are L-shaped and each has a guiding slope and a stop surface. The upper end of the guiding slope is located directly below the discharge end of the reject plate 6 to prevent the steel billet from falling between the receiving plate 1 and the reject plate 6. The stop surface prevents the steel billet from sliding off the receiving plate 1 due to the inertia of sliding down the guiding slope. A curved surface is provided between the guiding slope and the stop surface to connect the two. Support columns are provided on the receiving plate 1 below the guiding slope and the curved surface respectively. The support columns support the receiving plate 1 to ensure the stability of the receiving plate 1.

[0035] When the rolling mill or subsequent equipment fails, the controller controls the hydraulic cylinder 2 to operate, and the piston rod of the hydraulic cylinder 2 pushes the corresponding connecting rod 4 to rotate, and the articulated shaft 8 rotates. At the same time, the reject plate 6 rotates upward around the roller 7, and the reject plate 6 becomes an inclined surface. The steel billet on the roller 7 is lifted up by the five reject plates 6. In the process of lifting, the steel billet slides down from the inclined surface, slides off the roller 7 and slides onto the receiving plate 1. The utility model does not require manual operation to approach the high-temperature steel billet, thereby reducing the risk of manual operation, and does not require manual operation to hang the anchor chain or sling on the steel billet and then lift it by the overhead crane, thereby reducing operation time and improving operation efficiency.
