A roller discharge device

Abstract

This utility model provides a roller conveyor unloading device, including a frame, a first roller conveyor, and a second roller conveyor, which are arranged side by side on the frame. It also includes a first unloading plate arranged within the first roller conveyor, a second unloading plate arranged within the second roller conveyor, and a drive mechanism mounted on the frame for driving the first and second unloading plates to rotate. The first unloading plate has a first inclined surface, and the second unloading plate has a second inclined surface, which are coplanar. The drive mechanism is mounted on the frame and drives the first and second unloading plates to rotate. When channel steel needs to be unloaded simultaneously from the first and second roller conveyors, the drive mechanism drives the first and second unloading plates to rotate, lifting the channel steel upwards via the first and second inclined surfaces. Due to the presence of the first and second inclined surfaces, the channel steel slides downwards along them, thus achieving unloading.

Description

Technical Field

[0001] This utility model relates to the technical field of steel production equipment, specifically to a roller conveyor unloading device. Background Technology

[0002] In the existing channel steel rolling production process, channel steel is rolled from square billets into long strips, and then transferred to a more spacious conveyor via an unloading device. Once a sufficient number of channel steels have been gathered, they are uniformly sawn using a sawing machine.

[0003] Due to process improvements, the channel steel in the two parallel conveyor roller tracks needs to be unloaded onto the chain conveyor mechanism simultaneously for transport. However, the existing unloading mechanism cannot effectively unload the channel steel from the two conveyor roller tracks at the same time.

[0004] In summary, there is an urgent need for a roller conveyor unloading device to solve or at least partially solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a roller conveyor unloading device, which aims to solve the technical problem that the channel steel cannot be properly unloaded from the two conveyor roller conveyors after straightening. The specific technical solution is as follows:

[0006] A roller conveyor unloading device includes a frame, a first roller conveyor, and a second roller conveyor, which are arranged side-by-side on the frame. The device also includes a first unloading plate arranged within the first roller conveyor, a second unloading plate arranged within the second roller conveyor, and a drive mechanism mounted on the frame for driving the first and second unloading plates to rotate. The first unloading plate is hinged within the first roller conveyor, and the second unloading plate is hinged within the second roller conveyor. A first inclined surface is provided at the end of the first unloading plate away from the hinge point, and a second inclined surface is provided at the end of the second unloading plate away from the hinge point. The first and second inclined surfaces are arranged coplanarly. The drive mechanism is mounted on the frame for driving the first and second unloading plates to rotate.

[0007] Furthermore, the drive mechanism includes a linear drive assembly, the first end of which is hinged to the frame, and the second end of which is hinged to a first unloading plate or a second unloading plate.

[0008] Furthermore, the drive mechanism includes a swing arm and a linear drive assembly. The first end of the swing arm is fixedly connected to both the first and second unloading plates, and the second end of the swing arm is hinged to the linear drive assembly. The linear drive assembly is mounted on the frame.

[0009] Furthermore, multiple sets of first unloading plates, second unloading plates, and drive mechanisms are arranged, with these multiple sets of first unloading plates, second unloading plates, and drive mechanisms arranged at intervals along the conveying direction of the first roller conveyor.

[0010] Furthermore, it also includes a first guide plate, a second guide plate, and a third guide plate installed on the frame. The second guide plate is arranged between the first roller conveyor and the second roller conveyor, and the first guide plate and the third guide plate are respectively arranged on both sides of the first roller conveyor and the second roller conveyor.

[0011] Furthermore, it also includes a guide rod, the first end of which is connected to the first unloading plate and the second end of which is connected to the second unloading plate. A third inclined surface is provided on the guide rod, which is used to smoothly connect the first inclined surface and the second inclined surface. An avoidance groove is provided on the second guide plate, which is arranged corresponding to the guide rod.

[0012] Furthermore, it also includes a material guiding mechanism, which is mounted on the frame and arranged on the side close to the second roller conveyor; the first inclined surface is arranged inclined from the first roller conveyor toward the second roller conveyor; the material guiding mechanism includes a mounting frame and two sets of rollers arranged side by side on the mounting frame, the two sets of rollers being staggered relative to each other; both sets of rollers protrude upward from the mounting frame and are arranged inclined downward toward the side away from the second roller conveyor.

[0013] Furthermore, the roller assembly includes multiple bearings arranged in a straight line.

[0014] Furthermore, multiple material guiding mechanisms are arranged, and these multiple material guiding mechanisms are arranged at intervals along the conveying direction of the first roller conveyor.

[0015] The application of the technical solution of this utility model has the following beneficial effects:

[0016] When it is necessary to unload channel steel from the first and second roller conveyors simultaneously, the first and second unloading plates are driven to rotate by a drive mechanism. The channel steel is then lifted upwards by the first and second inclined planes. Due to the design of the first and second inclined planes, the channel steel slides downwards along them, thus achieving unloading. By adjusting the inclination angles of the first and second inclined planes, the channel steel can be easily unloaded from the first and second roller conveyors. The larger the inclination angles, the easier the unloading process.

[0017] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. These will be described below with reference to... Figures 1-7 The present invention will be described in further detail below. Attached Figure Description

[0027] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0029] Example 1:

[0030] See Figures 1-5This embodiment provides a roller conveyor unloading device, including a frame 1, a first roller conveyor 2, and a second roller conveyor 3. The first roller conveyor 2 and the second roller conveyor 3 are arranged side by side on the frame 1. It also includes a first unloading plate 4 arranged in the first roller conveyor 2, a second unloading plate 5 arranged in the second roller conveyor 3, and a drive mechanism 6 mounted on the frame 1 for driving the first unloading plate 4 and the second unloading plate 5 to rotate. The first unloading plate 4 is hinged in the first roller conveyor 2, and the second unloading plate 5 is hinged in the second roller conveyor 3. The end of the first unloading plate 4 away from the hinge point is provided with a first inclined surface 41, and the end of the second unloading plate 5 away from the hinge point is provided with a second inclined surface 51. The first inclined surface 41 and the second inclined surface 51 are arranged coplanarly. The drive mechanism 6 is mounted on the frame 1 and is used to drive the first unloading plate 4 and the second unloading plate 5 to rotate.

[0031] It is understood that when the channel steel in the first roller conveyor 2 and the second roller conveyor 3 needs to be unloaded simultaneously, the first unloading plate 4 and the second unloading plate 5 are driven to rotate by the drive mechanism 6. The channel steel is lifted upward by the first inclined surface 41 and the second inclined surface 51. Due to the setting of the first inclined surface 41 and the second inclined surface 51, the channel steel will slide downward along the first inclined surface 41 and the second inclined surface 51, thereby realizing unloading. It is worth noting that when the first inclined surface 41 and the second inclined surface 51 are set to be inclined towards the first roller conveyor 2, the channel steel in the first roller conveyor 2 and the second roller conveyor 3 will move along the second roller conveyor 3 towards the first roller conveyor 2 and be unloaded from the side of the first roller conveyor 2 away from the second roller conveyor 3. When the first inclined surface 41 and the second inclined surface 51 are set to be inclined towards the second roller conveyor 3, the channel steel in the first roller conveyor 2 and the second roller conveyor 3 will move along the first roller conveyor 2 towards the second roller conveyor 3 and be unloaded from the side of the second roller conveyor 3 away from the first roller conveyor 2.

[0032] Furthermore, the drive mechanism 6 includes a swing arm 62 and a linear drive assembly 61. The first end of the swing arm 62 is fixedly connected to both the first unloading plate 4 and the second unloading plate 5, and the second end of the swing arm 62 is hinged to the linear drive assembly 61. The linear drive assembly 61 is mounted on the frame 1. Specifically, the first unloading plate 4 is hinged to the frame 1 via a hinge shaft and is arranged within the first roller conveyor 2. The second unloading plate 5 is hinged to the frame 1 via the same hinge shaft and is arranged within the second roller conveyor 3. It should be noted that the first unloading plate 4 is fixedly connected to the hinge shaft, and the second unloading plate 5 is also fixedly connected to the hinge shaft. The hinge shaft is rotatably connected to the frame 1. When the first unloading plate 4 rotates, it will drive the second unloading plate 5 to rotate together, or when the second unloading plate 5 rotates, it will also drive the first unloading plate 4 to rotate together.

[0033] It can be seen that with this configuration, the swing arm 62 can be driven to rotate by the linear drive assembly 61, thereby driving the first unloading plate 4 and the second unloading plate 5 to rotate simultaneously to achieve unloading. It should be noted that in some other embodiments of this application, a connecting rod is also provided, and multiple sets of swing arms 62, first unloading plates 4 and second unloading plates 5 are provided. The first end of the swing arm 62 is fixedly connected to the corresponding first unloading plate 4 and second unloading plate 5. The second end of all swing arms 62 is hinged to the connecting rod, and all swing arms 62 are arranged parallel to each other. The fixed end of the linear drive assembly 61 is hinged to the frame 1, and the second end of the linear drive assembly 61 is hinged to the connecting rod. The linear drive assembly 61 drives the connecting rod to move, and the connecting rod simultaneously drives all swing arms 62 to swing. Thus, all first unloading plates 4 and second unloading plates 5 can be driven to rotate simultaneously by one linear drive assembly 61 and one connecting rod, which reduces the number of linear drive assemblies 61 used while improving the coordination and consistency of unloading and reducing production costs.

[0034] Preferably, in this embodiment of the application, the linear drive component 61 is a hydraulic cylinder. In some other embodiments of the application, the linear drive component 61 may also be an electric push rod or a pneumatic cylinder.

[0035] Furthermore, multiple sets of the first unloading plate 4, the second unloading plate 5, and the drive mechanism 6 are arranged, with these multiple sets of the first unloading plate 4, the second unloading plate 5, and the drive mechanism 6 spaced apart along the conveying direction of the first roller conveyor 2. Specifically, the distance between two adjacent sets of the first unloading plate 4, the second unloading plate 5, and the drive mechanism 6 is 3 meters. Of course, in some other embodiments, other distances can be set, generally between 2 meters and 4 meters.

[0036] It should be noted that after the channel steel is rolled and straightened, the channel steel itself is very long, with a single rolled channel steel being around 100 meters in length. The entire channel steel needs to be flipped and unloaded onto a wide conveyor chain that requires cutting. It can be understood that through the above structural design, by arranging multiple sets of first unloading plates 4, second unloading plates 5, and drive mechanisms 6 at intervals along the conveying direction of the first roller conveyor 2, the channel steel is supported at different locations during unloading. This improves the stability of the channel steel and facilitates smoother unloading. Insufficient support points would cause excessive deformation of the channel steel under gravity, leading to unloading failures. Therefore, the above structural design reduces the probability of unloading failures.

[0037] Furthermore, it also includes a first guide plate 7, a second guide plate 8, and a third guide plate 9 mounted on the frame 1. The second guide plate 8 is arranged between the first roller conveyor 2 and the second roller conveyor 3, and the first guide plate 7 and the third guide plate 9 are respectively arranged on both sides of the first roller conveyor 2 and the second roller conveyor 3. Specifically, the first guide plate 7, the second guide plate 8, and the third guide plate 9 are all fixedly connected to the frame 1 by welding; of course, in some other embodiments of this application, the first guide plate 7, the second guide plate 8, and the third guide plate 9 can also be detachably connected to the frame 1 by bolts.

[0038] It can be seen that the first guide plate 7 and the second guide plate 8 limit the channel steel in the first roller conveyor 2 to prevent the channel steel from deviating from its position during the conveying process of the first roller conveyor 2 and thus detaching from the first roller conveyor 2; the second guide plate 8 and the third guide plate 9 limit the channel steel in the second roller conveyor 3 to prevent the channel steel from deviating from its position during the conveying process of the second roller conveyor 3 and thus detaching from the second roller conveyor 3.

[0039] Furthermore, it also includes a guide rod 10, the first end of which is connected to the first unloading plate 4, and the second end of which is connected to the second unloading plate 5. A third inclined surface 101 is provided on the guide rod 10 to smoothly connect the first inclined surface 41 and the second inclined surface 51. A clearance groove 81 is provided on the second guide plate 8, corresponding to the guide rod 10. It should be noted that after the channel steel is straightened, the opening of the channel steel faces downwards. Therefore, during unloading, if there is a gap between the first unloading plate 4 and the second unloading plate 5, the channel steel may easily get stuck in the gap during unloading. Therefore, by setting the guide rod 10 between the first unloading plate 4 and the second unloading plate 5, the channel steel can be prevented from getting stuck during unloading. At the same time, the guide rod 10 connects the first unloading plate 4 and the second unloading plate 5 together, improving the overall integrity and rigidity between them. Meanwhile, the clearance groove 81 allows the first unloading plate 4, the second unloading plate 5, and the guide rod 10 to rotate smoothly, preventing the guide rod 10 from interfering with the second guide plate 8 when rotating with the first unloading plate 4 and the second unloading plate 5.

[0040] Furthermore, it also includes a material guiding mechanism 11, which is mounted on the frame 1 and arranged on the side close to the second roller conveyor 3; the first inclined surface 41 is arranged inclined from the first roller conveyor 2 toward the second roller conveyor 3; the material guiding mechanism 11 includes a mounting frame 111 and two sets of rollers 112 arranged side by side on the mounting frame 111, the two sets of rollers 112 being staggered relative to each other; both sets of rollers 112 protrude upward from the mounting frame 111 and are arranged inclined downward toward the side away from the second roller conveyor 3.

[0041] It should be noted that the first unloading plate 4 and the second unloading plate 5 are connected to the frame 1, which is the actual device for receiving the channel steel. During unloading, the channel steel tends to accumulate on the frame. The guide mechanism 11 ensures that the channel steel unloaded from the first unloading plate 4 and the second unloading plate 5 can smoothly enter the corresponding chain conveyor mechanism. Simultaneously, the staggered arrangement of the roller group 112 prevents the channel steel from getting stuck in the gap between the two rollers.

[0042] Furthermore, the roller assembly 112 includes multiple bearings 1121 arranged in a straight line. Specifically, the bearings 1121 can reduce friction through rolling; in this embodiment, the bearings 1121 are actually used as rollers. It should be noted that in steel rolling mills, a large number of rolling bearings 1121 are frequently replaced. After these rolling bearings 1121 wear out, their precision decreases, making them unusable at their original workstations. Installing the bearings 1121 into the roller assembly 112 is beneficial because the required precision for using the bearings 1121 as rollers is low, and the worn bearings 1121 are perfectly capable of functioning as rollers. Therefore, by setting up the bearings 1121, not only are the discarded bearings 1121 rationally utilized, but they also guide and transport the channel steel during unloading, preventing the channel steel from accumulating due to excessive resistance during transport.

[0043] Furthermore, multiple material guiding mechanisms 11 are arranged, and the multiple material guiding mechanisms 11 are arranged at intervals along the conveying direction of the first roller conveyor 2, that is, at intervals along the length direction of the channel steel.

[0044] It is known that the channel steel is guided by multiple guiding mechanisms 11, which provide sufficient support and guidance to prevent the channel steel from undergoing irreversible plastic deformation during unloading, or from being obstructed due to excessive deformation during unloading.

[0045] Example 2:

[0046] Reference Figure 6 and Figure 7 The difference between this embodiment and embodiment 1 is that in this embodiment, the drive mechanism 6 only includes a linear drive component 61. The first end of the linear drive component 61 is hinged to the frame 1, and the second end of the linear drive component 61 is hinged to the first unloading plate 4.

[0047] It is understood that the linear drive assembly 61 extends and retracts to drive the first unloading plate 4 to rotate, which in turn drives the second unloading plate 5 to rotate together, thereby unloading the channel steel in the first roller conveyor 2 and the second roller conveyor 3. It should be noted that in some other embodiments of this application, the second end of the linear drive assembly 61 is hinged to the second unloading plate 5.

[0048] The remaining aspects are basically the same as in Example 1, and will not be repeated here.

[0049] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
