Description

Technical Field

[0001] This utility model relates to the field of bar and wire production technology, specifically to a novel steel hook device for a feeding platform. Background Technology

[0002] In the production of bars and wire rods, the billet loading platform is a crucial piece of equipment for feeding steel billets into the heating furnace. A commonly used type is the motor-driven stepping billet loading platform, whose main function is to transport the billets one by one to the output roller conveyor, and then via the furnace inlet roller conveyor to the heating furnace. During the hoisting and stepping process of the billets on the stepping billet loading platform, the billet orientation may not be perpendicular to the platform's centerline. This can cause skewness during stepping, resulting in difficulties in unloading the billets, affecting the normal operation of subsequent processes, increasing downtime, and slowing down the production pace. Therefore, these problems urgently need to be addressed. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a new type of steel hook device for feeding platform, which has a simple structure, is easy to operate, reduces the failure rate of the feeding process, ensures the smooth progress of production, and improves production efficiency.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A novel steel-stopping hook device for a feeding platform of the present invention includes several feeding platforms for step-feeding; each feeding platform is horizontally arranged, and all feeding platforms are symmetrically arranged at intervals along the front-to-back direction; its innovation lies in that it also includes a steel-stopping hook, a calibration plate, a second rotating shaft, and a drive assembly; an inclined surface for allowing steel billets to fall is provided on the right side of each feeding platform, and steel-stopping hooks are vertically and horizontally arranged on the front and rear surfaces of each feeding platform relative to the upper end of the inclined surface; each steel-stopping hook is an inverted triangle. The steel billets are shaped such that their bottom surfaces are all horizontally arranged, and their top surfaces are all downward-facing. The left end of each steel hook is connected to the corresponding loading platform via a second rotating shaft arranged horizontally in the longitudinal direction, and a driving component is also linked to its top, which drives the steel hook to rotate vertically. A calibration plate is also vertically arranged on the bottom surface of each steel hook near its right end, and each calibration plate is integrally formed with the corresponding steel hook. Thus, when the bottom surface of the steel hook rotates to a horizontal state, the calibration plate adjusts the steel billet in the step-feeding process and makes it perpendicular to the transmission direction of the loading platform.

[0005] Preferably, the stepping feeding actions of several feeding platforms are synchronized, and the distance between the rear surface of the last feeding platform and the front surface of the foremost feeding platform is less than the length of the billet. Thus, when the billet is placed horizontally and longitudinally on the feeding platform and fed step by step, the position of the billet is adjusted by the calibration plate.

[0006] Preferably, each of the feeding platforms does not interfere with the vertical rotation of each of the steel stop hooks, and the position of each steel stop hook on the corresponding feeding platform must ensure that when the bottom surface of the steel stop hook is in a horizontal state, the ground surface of the steel stop hook does not interfere with the step feeding action of the steel billet.

[0007] Preferably, each of the calibration plates is a square plate arranged vertically and horizontally, and its height is required to ensure that when the bottom surface of the stop hook is horizontal, the left side of the calibration plate contacts the steel billet in the step feeding process, thereby adjusting the position of the steel billet.

[0008] Preferably, each of the feeding platforms does not interfere with the operation of each of the driving components, and each of the driving components includes a base plate, a mounting base, a first rotating shaft, a cylinder, and a connecting member; a base plate is horizontally provided on the ground relative to each stop hook position, and a vertically and horizontally arranged mounting base is symmetrically arranged at intervals on each of the base plates, and a first rotating shaft is horizontally and longitudinally rotatably arranged between each two adjacent mounting bases; the tail of each cylinder is fixedly installed on the corresponding first rotating shaft between the corresponding two mounting bases, and is vertically hinged to the corresponding mounting base through the first rotating shaft, ensuring that the rotation direction of the cylinder is consistent with the transport direction of the steel billet; the extension and retraction ends of each cylinder are arranged upwards, and are vertically hinged to the top of the corresponding stop hook through the connecting member, ensuring that the hinge direction of the two is consistent with the transport direction of the steel billet, thereby driving the corresponding stop hook to rotate around the second rotating shaft through the extension and retraction action of the cylinder.

[0009] Preferably, each cylinder also includes a bracket, an upper detection switch, and a lower detection switch; a U-shaped bracket is also provided on the left side of the tail of each cylinder, the opening slot of each bracket is arranged along the horizontal longitudinal direction, and both opening ends are arranged to the right, and are respectively fixedly connected to the upper and lower corresponding positions on the left side of the tail of the corresponding cylinder; an upper detection switch and a lower detection switch are also provided at intervals on the inner bottom surface of each bracket, and the sensing ends of each upper detection switch and lower detection switch are arranged to the right.

[0010] Preferably, each cylinder also includes a mounting plate, a connecting rod, a limiting block, and a counterweight. A mounting plate is vertically fixed on the left side of the telescopic end of each cylinder, and a connecting rod is vertically screwed onto the upper surface of each mounting plate. The lower end of each connecting rod extends downward along the length of the telescopic end of the cylinder into the corresponding bracket and is connected to the corresponding counterweight. Thus, during the process of the counterweight extending and retracting with the telescopic end of the cylinder via the connecting rod, the counterweight, in cooperation with the upper detection switch, limits the extension limit position of the telescopic end of the cylinder, and in cooperation with the lower detection switch, limits the retraction limit position of the telescopic end of the cylinder.

[0011] Preferably, a through hole matching the connecting rod is vertically embedded in the upper side of each bracket relative to the position of the connecting rod, and the connecting rod is slidably connected to the corresponding bracket through the through hole.

[0012] Preferably, when the extension end of each cylinder is extended to its limit position, it is necessary to ensure that the stop hook rotates counterclockwise until its bottom surface is horizontal; when the extension end of each cylinder is retracted, it is necessary to ensure that the stop hook rotates clockwise to the position below the billet in the step feeding process, and does not interfere with the transfer of the billet.

[0013] The beneficial effects of this utility model are: (1) This utility model has a simple structure and is easy to operate, which reduces the failure rate of the feeding process, ensures the smooth progress of production, and improves production efficiency; (2) This utility model can ensure that the billet is smoothly transported to the output roller table by calibrating the billet so that it is perpendicular to the conveying direction of the loading table.

Detailed Implementation

[0018] The technical solution of this utility model will be clearly and completely described below through specific embodiments.

[0019] This utility model discloses a novel steel hook device for a feeding platform, comprising several feeding platforms 1 for step-feeding; each feeding platform 1 is horizontally arranged, and all feeding platforms 1 are symmetrically arranged at intervals along the front-to-back direction; for example... Figure 1 , Figure 2As shown, it also includes a steel stop hook 8, a calibration plate 16, a second rotating shaft 9, and a drive assembly; a ramp for the billet 2 to fall is provided on the right side of each loading platform 1, and a steel stop hook 8 is provided vertically and horizontally on the front and rear surfaces of each loading platform 1 relative to the upper part of the ramp; each steel stop hook 8 is an inverted triangle, and its bottom surface is set horizontally, and its top surface is set downward; the left end of each steel stop hook 8 is connected to the corresponding loading platform 1 around its own axis through the horizontally longitudinally set second rotating shaft 9, and a drive assembly is also linked at its top, and the drive assembly drives the steel stop hook 8 to rotate vertically; a calibration plate 16 is also vertically provided on the bottom surface of each steel stop hook 8 near its right end, and each calibration plate 16 is integrally formed with the corresponding steel stop hook 8, so that when the bottom surface of the steel stop hook 8 rotates to a horizontal state, the calibration plate 16 adjusts the billet 2 in the step feeding process and makes it perpendicular to the transmission direction of the loading platform 1.

[0020] like Figure 1 , Figure 2 As shown, the stepping feeding actions of several feeding platforms 1 are synchronized, and the distance between the rear surface of the last feeding platform 1 and the front surface of the foremost feeding platform 1 is less than the length of the billet 2. Thus, when the billet 2 is placed horizontally and longitudinally on the feeding platform 1 and fed step by step, the position of the billet 2 is adjusted by the calibration plate 16.

[0021] like Figure 1 , Figure 2 As shown, each loading platform 1 does not interfere with the vertical rotation of each stop hook 8, and the position of each stop hook 8 on the corresponding loading platform 1 must ensure that when the bottom surface of the stop hook 8 is in a horizontal state, the ground surface of the stop hook 8 does not interfere with the stepping loading action of the billet 2.

[0022] like Figure 1 , Figure 2 As shown, each calibration plate 16 is a square arranged vertically and horizontally, and its height must ensure that when the bottom surface of the stop hook 8 is in a horizontal state, the left side of the calibration plate 16 contacts the steel billet 2 in the step feeding, thereby adjusting the position of the steel billet 2.

[0023] In this utility model, each loading platform 1 does not interfere with the operation of each driving component, and each driving component includes a base plate 3, a mounting base 4, a first rotating shaft 5, a cylinder 6, a connecting piece 7, a bracket 12, an upper detection switch 13, a lower detection switch 14, a mounting plate 10, a connecting rod 11, a limit block, and a counterweight 15; Figure 1 , Figure 2As shown, a base plate 3 is horizontally provided on the ground relative to each stop hook 8 position, and a vertically horizontally arranged mounting seat 4 is symmetrically arranged at intervals on each base plate 3. A first rotating shaft 5 is also horizontally and longitudinally rotatably arranged between each two adjacent mounting seats 4. The tail of each cylinder 6 is fixedly installed on the corresponding first rotating shaft 5 between the corresponding two mounting seats 4, and is vertically hinged to the corresponding mounting seat 4 through the first rotating shaft 5, ensuring that the rotation direction of the cylinder 6 is consistent with the transmission direction of the billet 2. The telescopic end of each cylinder 6 is set upward, and is vertically hinged to the top of the corresponding stop hook 8 through the connecting piece 7, ensuring that the hinge direction of the two is consistent with the transmission direction of the billet 2. Then, through the extension and retraction action of the telescopic end of the cylinder 6, the corresponding stop hook 8 is driven to rotate around the second rotating shaft 9.

[0024] like Figure 1 , Figure 2 As shown, a U-shaped bracket 12 is provided on the left side of the tail of each cylinder 6. The opening slot of each bracket 12 is arranged along the horizontal longitudinal direction, and both opening ends are arranged to the right. They are fixedly connected to the corresponding upper and lower positions on the left side of the tail of the corresponding cylinder 6. An upper detection switch 13 and a lower detection switch 14 are provided on the inner bottom surface of each bracket 12 at intervals, and the sensing ends of each upper detection switch 13 and lower detection switch 14 are arranged to the right.

[0025] like Figure 1 , Figure 2 As shown, a mounting plate 10 is vertically fixed on the left side of the telescopic end of each cylinder 6, and a connecting rod 11 is vertically screwed onto the upper surface of each mounting plate 10. The lower end of each connecting rod 11 extends downward along the length of the telescopic end of the cylinder 6 into the interior of the corresponding bracket 12, and is connected to the corresponding counterweight 15. Thus, during the process of the counterweight 15 extending and retracting with the telescopic end of the cylinder 6 through the connecting rod 11, the counterweight 15, in cooperation with the upper detection switch 13, limits the extension limit position of the telescopic end of the cylinder 6, and in cooperation with the lower detection switch 14, limits the retraction limit position of the telescopic end of the cylinder 6.

[0026] like Figure 1 , Figure 2 As shown, a through hole matching the connecting rod 11 is vertically embedded on the upper side of each bracket 12 relative to the position of the connecting rod 11, and the connecting rod 11 is slidably connected to the corresponding bracket 12 through the through hole. Specifically, when the extension end of each cylinder 6 is extended to its limit position, it must ensure that the stop hook 8 rotates counterclockwise until its bottom surface is horizontal; when the extension end of each cylinder 6 is retracted, it must ensure that the stop hook 8 rotates clockwise to below the steel billet 2 in the stepping feeding process, without interfering with the transmission of the steel billet 2.

[0027] The working principle of this utility model is as follows: First, the telescopic end of the cylinder 6 extends, causing the weight 15 to rise along the connecting rod 11. At this time, the stop hook 8 rotates counterclockwise around the second rotating shaft 9. When the weight 15 contacts the upper detection switch 13, it indicates that the stop hook 8 has rotated counterclockwise to its limit position. At this time, the calibration plate 16 can contact the billet 2 that is stepping on the loading platform 1 to adjust the billet 2 so that it is perpendicular to the transmission direction of the loading platform 1. Then, the telescopic end of the cylinder 6 retracts, causing the weight 15 to fall along the connecting rod 11. At this time, the stop hook 8 rotates clockwise around the second rotating shaft 9. When the weight 15 contacts the lower detection switch 14, it indicates that the stop hook 8 has rotated clockwise to its limit position. At this time, the calibration plate 16 and the stop hook 8 no longer interfere with the stepping action of the billet 2. The calibrated billet 2 can then be transported to the output roller conveyor through the loading platform 1, and then transported into the furnace by the furnace inlet roller conveyor.

[0028] The beneficial effects of this utility model are: (1) This utility model has a simple structure and is easy to operate, which reduces the failure rate of the feeding process, ensures the smooth progress of production, and improves production efficiency; (2) This utility model can ensure that the billet 2 is smoothly transported to the output roller table by calibrating the billet 2 so that it is perpendicular to the conveying direction of the loading table 1.

[0029] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the concept and scope of the present utility model. Without departing from the design concept of the present utility model, all modifications and improvements made by those skilled in the art to the technical solutions of the present utility model should fall within the protection scope of the present utility model. The technical content for which protection is sought in the present utility model has been fully recorded in the technical requirements.
