Description

Technical Field

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

[0002] Steel billet is the product obtained by casting the molten steel from the steelmaking furnace. After processing, it can be used to make mechanical parts, forgings, and various steel products, such as Q345B channel steel and wire rod.

[0003] In the rolling production line, lifting and transportation are essential links in the process of conveying steel billets. After the steel billets are produced by the continuous casting line, they are lifted from the continuous casting platform to the heating furnace platform by the hoist. The steel billets slide down the slide of the hoist into the chute, and then the flat support mechanism supports the steel billets from the chute to the furnace roller, and then they are sent to the heating furnace for heating. After the steel billets are lifted from the low position to the high position, the steel billets fall directly onto the roller through the slide, which makes the roller easy to be damaged and greatly reduces its service life. Therefore, it is necessary to install a buffer device for the steel billets here to buffer the sliding process of the steel billets and release the impact force of the steel billets to protect the equipment from being damaged and ensure the smooth progress of production. In the prior art, hydraulic or pneumatic components are generally used to drive the gear lever for buffering. That is, when the steel billets are about to be fed, they are blocked by a gear lever, and when the steel billets slide down, they hit the gear lever for buffering.

[0004] The Chinese patent with the existing authorization announcement number (CN203753923U) discloses a material blocking device for a steel billet conveying and hoisting machine, including a hydraulic driving device, a hydraulic push rod is arranged on the hydraulic driving device, the hydraulic push rod is connected to a stopper through a connecting shaft, the stopper is fixed to a hollow base through a fixed shaft perpendicular to the stopper, and the stopper rotates around the fixed shaft with the fixed shaft as a fulcrum. The beneficial effects of this utility model are: the stopper is added, which can effectively buffer the speed of the steel billet falling. When the steel billet falls on the stopper, the stopper is stressed and rotates downward around the fixed shaft. At the same time, the connecting shaft drives the hydraulic push rod. The existence of the stopper slows down the falling speed, reduces the impact of the steel billet on the roller, effectively protects the roller, and prolongs the service life of the roller.

[0005] However, in the use of this utility model, the pressure on the lever is too great, and the falling of the steel billet will cause strong rigid gravity pressure on the lever. During long-term use, it is easy to be damaged, resulting in a relatively short service life and high replacement cost.

[0006] In order to solve the above problems, we propose a buffer device for billet conveying to solve the above problems. Utility Model Content

[0007] In order to solve the problems in the background technology, the utility model provides a buffer device for conveying steel billets.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0010] A shock absorbing mechanism is arranged in the middle of the bottom end of the support seat; the shock absorbing mechanism includes multiple groups of spring shock absorbers, which are fixedly installed in the middle of the inner side of the installation cavity, and the tops of the multiple groups of spring shock absorbers are fixedly connected to the bottom end of the support seat. The multiple groups of spring shock absorbers play the role of elastic shock absorption, effectively alleviating the impact force caused by the steel billet on the gear lever and the support seat.

[0011] The shock absorbing mechanism also includes multiple sets of gears, which are rotatably installed on both sides of the bottom end of the support seat respectively. Racks are provided in the middle of both ends of the installation cavity. The gears are meshed and connected with the racks. The gears are meshed and connected with the racks. The gears are rotated to increase friction and alleviate the effect of the support seat descending. At the same time, they also play a limiting role to prevent the support seat from tilting due to force.

[0012] Preferably, a fixing seat is provided in the middle of the bottom end of the hydraulic push rod, the fixed end of the hydraulic push rod is rotatably mounted in the middle of the upper end of the fixing seat, and the fixing seat is provided in the middle of the side end of the hollow base.

[0014] Preferably, the gear lever has a rotation angle of 0-50 degrees, and the gear lever will rotate when subjected to pressure to relieve the impact force.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0018] The main process is that when the steel billet falls onto the gear rod, the pressure force it generates will impact the gear rod, thereby generating gravity pressure on the support seat at the bottom. When the support seat is subjected to gravity pressure, it will move downward. At this time, the friction force is increased by meshing and rotating between the gear and the rack, which effectively alleviates the impact pressure on the support seat. At the same time, multiple groups of spring shock absorbers are arranged in the middle of the bottom end of the support seat. During the descent of the support seat, the multiple groups of spring shock absorbers will be squeezed, thereby generating a rebound force, further alleviating the descent speed of the support seat, thereby playing a role of elastic buffering for the gear rod and the support seat.

[0024] The embodiment of the present application provides a buffer device for conveying steel billets, which is equipped with a shock-absorbing mechanism to alleviate the gravity impact generated when the steel billet falls, reduce the hard impact and pressure caused by the steel billet on the gear rod 4 and the support seat 8, and mainly play the role of elastic buffering for the gear rod 4 and the support seat 8, effectively alleviate the impact damage caused by the steel billet to the gear rod 4 and the support seat 8, and improve the service life of the gear rod 4 and the support seat 8.

[0025] Example: Refer to Figure 1-4 As shown, a buffer device for conveying steel billets in this embodiment includes a hydraulic push rod 1 and a gear rod 4. The hydraulic push rod 1 and the gear rod 4 are movably connected via a connecting shaft 3. A hollow base 7 is provided at the bottom end of the gear rod 4. A mounting cavity 9 is provided in the middle inner part of the hollow base 7. A support seat 8 is provided in the middle inner part of the mounting cavity 9. A rotating shaft 5 is rotatably installed in the middle inner part of the support seat 8. The rotating shaft 5 passes through the bottom of the gear rod 4 and is fixedly connected to the gear rod 4. A fixed seat 2 is provided in the middle bottom end of the hydraulic push rod 1. The fixed end of the hydraulic push rod 1 is rotatably installed in the middle upper end of the fixed seat 2. The fixed seat 2 is provided in the middle side end of the hollow base 7.

[0026] Among them, the steel billet transported by the conveyor belt can be resisted by the gear rod 4. When the steel billet falls on the gear rod 4, the gear rod 4 is subjected to force, and the rotating shaft 5 will rotate, and at the same time, the connecting shaft 3 will be driven to move. Under the pulling of the connecting shaft 3, a pulling force will be generated on the hydraulic push rod 1. The hydraulic push rod 1 can reduce the rotation speed of the gear rod 4, ensuring that the gear rod 4 is effectively buffered after being subjected to force. After being buffered by the gear rod 4, the steel billet falls onto the roller again, which effectively relieves the impact force on the roller, protects the roller, and thus prolongs the service life of the roller.

[0027] The rotation angle of the gear lever 4 is 0-50 degrees.

[0028] In addition, a shock absorbing mechanism is provided in the middle of the bottom end of the support seat 8 to play the role of elastic shock absorption, reduce the impact force generated by the steel billet, and relieve the impact on the gear lever 4.

[0029] The shock absorbing mechanism includes multiple groups of spring shock absorbers 10, which are fixedly installed in the middle of the inner side of the installation cavity 9. The tops of the multiple groups of spring shock absorbers 10 are fixedly connected to the bottom end of the support seat 8, and the spring shock absorbers 10 play the role of elastic support for the support seat 8.

[0030] When the steel billet falls from the feeding belt onto the gear rod 4, the weight it generates will cause pressure on the gear rod 4 and the support seat 8. At this time, multiple sets of spring shock absorbers 10 can buffer the gravity pressure, avoiding the pressure generated by the falling steel billet on the gear rod 4 and the support seat 8 to cause a hard impact, effectively alleviating the pressure on the gear rod 4 and the support seat 8.

[0031] Among them, the shock absorbing mechanism also includes multiple sets of gears 11, which are rotatably installed on both sides of the bottom end of the support seat 8. Racks 12 are arranged in the middle of both ends of the installation cavity 9. The gears 11 are meshed and connected with the racks 12. When the support seat 8 is subjected to pressure, it will move downward, thereby driving the gears 11 to rotate. The meshing rotation between the gears 11 and the racks 12 increases the friction force, further alleviates the impact force on the support seat 8, and at the same time, it also plays a role of limiting, avoiding the support seat 8 from tilting when the elastic force is raised and lowered.

[0032] In some examples, a mounting base plate 6 is disposed at the middle of the bottom end of the hollow base 7 .

[0033] The working principle of the utility model is:

[0034] The main technology of the present invention is to provide a gear lever 4, a support seat 8 is provided at the middle of the bottom end of the gear lever 4, and a shock absorbing mechanism is provided at the bottom end of the support seat 8. When the steel billet falls on the gear lever 4, the pressure generated by it will impact the gear lever 4, thereby generating gravity pressure on the support seat 8 at the bottom;

[0035] When the support seat 8 is pressed by gravity, it will move downward. At this time, the gear 11 will rotate at the side end of the rack 12, driving the support seat 8 to descend. The gear 11 and the rack 12 are meshed and rotated to increase the friction force, effectively alleviating the impact force on the support seat 8. At the same time, a spring shock absorber 10 is also provided in the middle of the bottom end of the support seat 8. During the descent of the support seat 8, the spring shock absorber 10 will be squeezed, thereby generating a rebound force, further alleviating the descent speed of the support seat 8.

[0036] The shock absorbing mechanism mainly plays a role of buffering and protecting the shift rod 4 and the support seat 8, effectively alleviating the damage of the steel billet to the shift rod 4 and the support seat 8, and prolonging the service life of the shift rod 4 and the support seat 8.

[0037] When the lever 4 is subjected to force, it will rotate to relieve the impact force on the lever 4. After the steel billet is buffered by the lever 4, the impact force on the roller is effectively relieved, which plays a protective role on the roller, thereby extending the service life of the roller.

[0038] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
