Description

Technical Field

[0001] This utility model relates to the field of walking beam technology, specifically a walking beam anti-collision device. Background Technology

[0002] Walking beams are a common type of metallurgical equipment, mainly used for transporting rolled steel. They achieve the step-by-step handling of rolled steel through periodic motion and are widely used in processes such as steel rolling mills, cold rolling, galvanizing, and continuous annealing lines. Walking beams achieve the step-by-step handling of rolled steel through the periodic motion of the moving beam, which is divided into two parts: translational motion and lifting motion. The translational motion and lifting motion are generally driven by hydraulic cylinder devices.

[0003] However, due to the large mass and high temperature of the rolled steel, the surface of the moving beam will deform under high load for a long time, which reduces the durability of the moving beam in the walking beam. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, this utility model proposes a step beam anti-collision device by using an anti-collision mechanism on the moving beam to prevent rigid collisions between the moving beam and the upper rolled steel, while the heat dissipation holes on the upper plate can provide a certain degree of cooling.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a step beam anti-collision device, including a step beam body including a frame and a moving beam, wherein the moving beam is disposed in the frame and an anti-collision mechanism is provided on the moving beam;

[0006] The anti-collision mechanism is symmetrically arranged on both sides of the moving beam. The anti-collision mechanism includes a lower plate and an upper plate with heat dissipation holes on its surface. The lower plate is detachably installed on one side of the moving beam. A spring anti-collision assembly and an auxiliary support assembly are provided between the lower plate and the upper plate. The two ends of the spring anti-collision assembly are fixedly connected to the lower plate and the upper plate, respectively. The auxiliary support assembly includes a limiting slide, which is slidably connected between the lower plate and the upper plate. A first support rod and a second support rod are rotatably connected between the limiting slides.

[0007] Preferably, the moving beam has a side groove, the anti-collision mechanism is located on the outside of the side groove, the lower end of the side groove has an installation groove, and one side of the top of the side groove has a support groove.

[0008] Preferably, five sets of mounting slots are equidistantly arranged, and two sets of threaded holes are symmetrically opened in each set of mounting slots. The lower end of the lower plate is integrally formed with a mounting part, and a through hole is opened on the mounting part. The lower plate is detachably installed on one side of the moving beam by fixing bolts.

[0009] Preferably, the spring anti-collision assembly is disposed on the upper part of the mounting groove. The spring anti-collision assembly includes a lower sleeve and an upper support column that are slidably inserted. The lower sleeve and the upper support column are welded and fixed to the lower plate and the upper plate respectively. A compression spring is welded inside the lower sleeve, and the upper end of the compression spring is welded and fixed to the lower end of the upper support column.

[0010] Preferably, the auxiliary support components are arranged at equal intervals, and the auxiliary support components are spaced apart between the five sets of spring anti-collision components. Limiting grooves are provided on the lower plate and the upper plate, and the limiting slide is slidably connected to the lower plate and the upper plate through the limiting grooves.

[0011] Preferably, the upper part of the limiting slide is provided with a rotating connection hole, and the two sides of the ends of the first support rod and the second support rod are integrally formed with rotating connection columns. The first support rod and the second support rod are rotatably connected to the limiting slide through the cooperation of the rotating connection columns and the rotating connection hole.

[0012] Preferably, the first support rod has an integrally formed insertion part in the middle, and a groove is formed on the insertion part. The second support rod passes through the groove and is inserted into the groove. A bearing is embedded in the groove, and the second support rod is rotatably connected to the first support rod through the bearing.

[0013] The advantages of this utility model are:

[0014] 1. This utility model uses the periodic vertical and horizontal movement of a moving beam to drive the upper rolled steel in a step-by-step conveying manner. Both sides of the moving beam are equipped with anti-collision mechanisms for initial contact and buffering with the conveyed rolled steel. Before contact with the rolled steel, the upper plate rises under the action of the spring anti-collision components. As the moving beam rises, the upper plate first contacts the rolled steel. As the moving beam continues to move upward, the elastic force of the compression spring at the bottom of the upper plate gradually increases until the contact between the moving beam and the rolled steel reaches its maximum. This significantly reduces the pressure on the upper surface of the moving beam when in contact with the rolled steel. Furthermore, the upper plate is provided with heat dissipation holes, which can dissipate the heat transferred from itself and the moving beam, thereby reducing the deformation of the upper surface of the walking beam during long-term high-load operation and improving the durability of the walking beam.

[0015] 2. This utility model provides an auxiliary support component between the spring anti-collision components. The auxiliary support component, together with the support groove on the side of the moving beam, can support the upper plate, making the lifting and lowering of the upper plate smoother and improving the stability of the upper plate when it bears the weight of the upper rolled steel on its own.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0025] The following is in conjunction with the appendix Figure 1-6 This application provides further details:

[0026] This application discloses a walking beam anti-collision device. (Refer to...) Figure 1 and Figure 2 The walking beam body 1 includes a frame 101 and a moving beam 102. The moving beam 102 is installed in the frame 101. The lower part of the moving beam 102 is equipped with a lifting hydraulic cylinder and a horizontal movement hydraulic cylinder for step-by-step conveying of the rolled steel above the frame 101.

[0027] Reference Figure 3 and Figure 4 A collision protection mechanism 2 is provided on the moving beam 102. The collision protection mechanism 2 is symmetrically arranged on both sides of the moving beam 102. The collision protection mechanism 2 includes a lower plate 201 and an upper plate 202. A side groove 103 is provided on the moving beam 102, and an installation groove 104 is provided at the lower end of the side groove 103. Five sets of installation grooves 104 are equidistantly arranged, and two sets of threaded holes 106 are symmetrically provided in each set of installation grooves 104. A mounting part 206 is integrally formed at the lower end of the lower plate 201, and a through hole is provided on the mounting part 206. The lower plate 201 is detachably installed on one side of the moving beam 102 by fixing bolts. After long-term use, the collision protection mechanism 2 will also deform and suffer metal fatigue. It can be disassembled by the bolts on the side to replace the internal spring and the upper plate 202.

[0028] Reference Figure 4 and Figure 6 A spring anti-collision assembly 20 and an auxiliary support assembly 21 are provided between the lower plate 201 and the upper plate 202. The two ends of the spring anti-collision assembly 20 are fixedly connected to the lower plate 201 and the upper plate 202, respectively. The spring anti-collision assembly 20 is located on the upper part of the mounting groove 104. The spring anti-collision assembly 20 includes a lower sleeve 208 and an upper support column 209 that are slidably inserted. The lower sleeve 208 and the upper support column 209 are welded and fixed to the lower plate 201 and the upper plate 202, respectively. A compression spring 210 is welded inside the lower sleeve 208, and the upper end of the compression spring 210 is connected to the lower end of the upper support column 209. The welding fixation and the compression spring 210 can lift the upper plate 202. When the moving beam 102 moves upward, the compression spring 210 can relieve the force and reduce the rigid collision amplitude between the moving beam 102 and the rolled steel. A support groove 105 is opened on one side of the top of the side groove 103. When the upper plate 202 is compressed to the lowest point, it will engage with the support groove 105, so as to share the force with the moving beam 102. This increases the force-bearing area above the stepping beam, so that the pressure can be dispersed. The combination of increasing the surface area and opening double rows of heat dissipation holes 207 can better dissipate the heat transferred from the rolled steel to the upper plate 202 and the moving beam 102.

[0029] Reference Figure 4 and Figure 5The auxiliary support component 21 includes a limiting slide 203. The auxiliary support components 21 are arranged at equal intervals and are spaced between five sets of spring anti-collision components 20. The lower plate 201 and the upper plate 202 are provided with limiting slide grooves 211, and the limiting slide 203 is slidably connected to the lower plate 201 and the upper plate 202 through the limiting slide grooves 211. The limiting slide 203 and the limiting slide grooves 211 are T-shaped, which can effectively prevent the upper and lower plates from falling off.

[0030] Reference Figure 4 and Figure 5 A first support rod 204 and a second support rod 205 are rotatably connected between the limiting slides 203. A rotatable connection hole 212 is provided on the upper part of the limiting slide 203. Rotary connection columns 213 are integrally formed on both sides of the ends of the first support rod 204 and the second support rod 205. The first support rod 204 and the second support rod 205 are rotatably connected to the limiting slide 203 through the cooperation of the rotatable connection columns 213 and the rotatable connection hole 212.

[0031] Reference Figure 4 and Figure 5 The first support rod 204 and the second support rod 205 are rotatably connected. The first support rod 204 has an integrally formed insertion part 214 in the middle. The insertion part 214 has a groove 215. The second support rod 205 passes through the insertion groove 215 and a bearing is embedded in the groove 215. The second support rod 205 is rotatably connected to the first support rod 204 through the bearing. When the upper plate 202 is compressed to the lowest point, the limiting slide 203 will contact the inner wall of the limiting slide groove 211, thereby providing support for the middle of the upper plate 202 and the lower plate 201 and improving the stability between the upper plate 202 and the lower plate 201.

[0032] Working principle: The lower part of the moving beam 102 is equipped with a lifting hydraulic cylinder and a horizontal movement hydraulic cylinder, which are used to perform step-by-step conveying of the rolled steel above the frame 101. After the rolled steel is delivered from the furnace to the frame 101 above the walking beam body 1, the lifting hydraulic cylinder first extends upward, then the horizontal hydraulic cylinder extends, and then the lifting hydraulic cylinder descends again, completing one cycle of step-by-step conveying. When the moving beam 102 conveys the rolled steel, the upper plate 202 will first contact the rolled steel, and as the moving beam 102 continues to move upward... As the movement progresses, the spring force of the compression spring 210 at the lower part of the upper plate 202 gradually increases until the spring force of the compression spring 210 reaches its maximum when the moving beam 102 contacts the rolled steel. This significantly reduces the pressure when the upper surface of the moving beam 102 contacts the rolled steel. The upper plate 202 increases the force-bearing area above the stepping beam, allowing the pressure to be dispersed. At the same time, the combination with the double-row heat dissipation holes 207 allows the heat transferred from the rolled steel to the upper plate 202 and the moving beam 102 to be better dissipated.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
