Description

Technical Field

[0001] This utility model relates to auxiliary equipment for steel rolling processes, specifically to a billet support device. Background Technology

[0002] The billet loading platform includes several moving beams and stationary beams, which are arranged in sequence at intervals. A roller is installed on one side of the moving beam and stationary beam along their length. The roller is mounted on a roller bracket via bearings and is driven to rotate by a motor. See patent CN200920128559.7--Steel Billet Loading Platform Stationary Beam and patent CN201210580002.3---Cold Billet Loading Platform.

[0003] In particular, in patent CN200920128559.7--Steel billet loading platform static beam, a steel billet loading platform static beam is disclosed. The static beam is equipped with a lower steel billet inclined surface, and a buffer section is set at the lower end of the lower steel billet inclined surface. By adopting the structure of setting a buffer section at the lower end of the lower steel billet inclined surface, during the steel billet unloading process, the steel billet first impacts the buffer section and then falls onto the idler roller. This can reduce the impact of the steel billet on the idler roller, avoid damage to the roller and motor, ensure normal production, reduce spare parts consumption, and lower maintenance and use costs.

[0004] However, in actual use, the billet is located on the stationary beam, and the moving beam lifts the billet and moves forward on the stationary beam. At the end of the stationary beam, the billet slides onto the idler roller. Although there is a buffer section, the billet slides down quickly due to the large height difference between the stationary beam and the idler roller. Therefore, when the billet slides onto the idler roller, it still exerts a large impact force on the idler roller. This impact force can still cause the installation accessories of the idler roller to loosen or be damaged. Summary of the Invention

[0005] This utility model provides a billet support device for installation on one side of the roller of the billet loading platform. Each roller can correspond to one billet support device, or the billet support devices can be set at intervals, and the billet support devices are kept at a distance from the roller. In use, its first side is in a horizontal state. The billet that is flipped towards the roller by the moving beam is first flipped onto the first side of the plate to avoid the billet directly flipping onto the roller, which would cause impact to the roller and damage various installation parts of the roller.

[0006] The technical solution adopted by this utility model is: a billet support device, which is installed on one side of the support roller of the billet loading platform, including a plate, a power mechanism and a base. One end of the plate is rotatably connected to the base and the other end is connected to the power mechanism. The power mechanism drives the plate to rotate around the base. The plate has a first side and a second side. When the first side rotates to the horizontal, the height of the first side is at least not lower than the height of the upper edge of the roller surface.

[0007] Based on the above scheme, as a preferred option, when the first side is rotated to the horizontal position, the height of the first side protrudes 2-4 cm above the upper edge of the roller surface.

[0008] Based on the above scheme, as a preferred embodiment, the base includes a fixing plate, which is used to fix and connect with the static beam, the ground, or any fixed carrier. A first support is fixedly installed at one end of the fixing plate, and a second support is fixedly installed at the other end. One end of the connecting shaft is connected to the first support, and the other end is connected to the second support.

[0009] Based on the above scheme, as a preferred option, the connection between the connecting shaft and the first support and the second support can be a fixed connection.

[0010] Based on the above scheme, as a preferred option, after the first support and the second support are fixed on the fixed plate, the C-shaped hoop 6 hugs the first support and the second support and is then fixed to the fixed plate by bolts.

[0011] Based on the above scheme, as a preferred option, the plate is triangular, one end of the plate is rotatably connected to the connecting shaft, specifically through a bearing, and two connecting plates are welded to the other end of the plate to form a Y-shaped joint. The Y-shaped joint is hinged to the end of the telescopic rod of the cylinder, which serves as the power mechanism, through a pin. The cylinder body is hinged to the ground or a carrier fixed to the ground.

[0012] Based on the above scheme, as a preferred option, the billet loading platform has at least 6 rollers, and a billet support device is installed on one side of the 2nd and 5th rollers, with a gap between the billet support device and the roller.

[0013] Based on the above scheme, as a preferred option, one idler roller corresponds to one billet support device, and there is a gap between the billet support device and the idler roller.

[0014] Based on the above scheme, as a preferred option, when the first side is in a horizontal state, the end of the first side that is far from the static beam has a protrusion, and a wear-resistant block is fixedly installed on the side of the protrusion facing the static beam.

[0015] Based on the above scheme, as a preferred option, the wear-resistant block is fixedly installed on the protrusion by countersunk bolts.

[0016] The present invention has the following technical advantages: This utility model is used to install on one side of the idler roller of the billet loading platform. Each idler roller can correspond to one billet support device, or the billet support devices can be set at intervals, and the billet support devices are kept at a distance from the idler roller. In use, its first side is in a horizontal state. The billet that is flipped towards the idler roller by the moving beam is first flipped onto the first side of the plate to avoid the billet being flipped directly onto the idler roller, which would cause impact to the idler roller and damage various installation parts of the idler roller.

[0017] When the first side is rotated to a horizontal position, its height should be at least as high as the top edge of the roller surface, preferably 2-4 cm above the top edge. This ensures that the height difference between the billet sliding down the first side and the roller is not too large, protecting the support device and the roller and extending their service life.

[0018] The service life of the plate is improved by adding wear-resistant blocks. The countersunk bolts do not protrude from the wear-resistant blocks, so the steel billet will not be scratched when it hits the wear-resistant blocks. Attached Figure Description

[0019] Figure 1 This is a schematic diagram of the structure of this utility model; Figure 2 This is the front view of this utility model. Detailed Implementation

[0020] To further understand this utility model, the following detailed description is provided in conjunction with embodiments. However, this is not intended to limit the scope of the utility model. It should be understood that these descriptions are only for further illustrating the features and advantages of the utility model, and not for limiting the scope of the claims. Any equivalent substitutions made in the art based on the disclosure of this utility model are within the protection scope of this utility model.

[0021] Example 1, as Figure 1-2 As shown, a billet support device is used on a billet loading platform. The billet support device includes a plate 1, a power mechanism, and a base. One end of the plate is rotatably connected to the base, and the other end is connected to the power mechanism. The power mechanism drives the plate to rotate around the base. The plate has a first side 8 and a second side 7. During the rotation of the plate driven by the power mechanism, when the first side rotates to a horizontal position, the height of the first side is at least not lower than the height of the upper edge of the roller surface of the idler roller. Preferably, it protrudes 2-4 cm above the upper edge of the roller surface. This dimension is determined by the height difference between the stationary beam and the upper edge of the roller surface. Usually, the median of the height difference is taken as the optimal solution, so that the height difference between the billet sliding onto the first side and sliding onto the idler roller from the first side is not too large, thus protecting the support device and the idler roller and extending their service life.

[0022] The base includes a fixing plate 2, which is used to fix and connect with a static beam, the ground, or any fixed carrier. The fixing and connection can be done by welding, bolting, etc. A first support 3 is fixedly installed at one end of the fixing plate (removable fixing, such as bolting), and a second support 4 is fixedly installed at the other end. One end of the connecting shaft 5 is connected to the first support, and the other end is connected to the second support.

[0023] Of course, the connection between the connecting shaft and the first and second supports can be either a fixed connection or a rotatable connection.

[0024] To ensure a secure connection, after the first and second supports are on the fixed plate, the C-shaped clamps 6 hold the first and second supports and are then fixed to the fixed plate with bolts.

[0025] The plate can theoretically be of any shape. In this application, the plate is triangular. One end of the plate is rotatably connected to the connecting shaft, specifically through a bearing. Two connecting pieces 9 are welded to the other end of the plate to form a Y-shaped joint. The Y-shaped joint is hinged to the end of the telescopic rod of the cylinder 10, which serves as the power mechanism, through a pin. The cylinder body is hinged to the ground or a carrier fixed to the ground.

[0026] When the first side is horizontal, its length is longer than the roller surface of the idler roller, that is, the left end of the first side is located to the left of the left end of the idler roller, and the cylinder is located directly below the Y-shaped joint, that is, its telescopic rod is in a vertical state.

[0027] Of course, the plate can also be fixedly connected to the connecting shaft. When it is fixedly connected to the connecting shaft, the connecting shaft needs to be rotatably connected to the first support and the second support.

[0028] Example 2: For a billet loading platform, since the billet it conveys is relatively long, the number of idlers is usually more than 6 to form a roller conveyor for conveying the billet. However, the length of billets varies from batch to batch. Therefore, in order to save costs, a billet support device is installed on one side of the 2nd and 5th idlers, based on a certain section of the billet conveying direction. There is an interval between them so as not to interfere with the operation of the idlers. Of course, one idler can also correspond to one billet support device.

[0029] The plate adopts an obtuse-angled triangular structure with rounded corners at the two acute angles. When the first side is rotated to a horizontal position, the second side tilts. The base is supported by the ground or the lower part of the static beam.

[0030] In Example 3, when the first side is in a horizontal state, a protrusion 11 is provided at the end of the first side furthest from the stationary beam, and a wear-resistant block 12 is fixedly installed on the side of the protrusion facing the stationary beam. The wear-resistant block is fixedly installed on the protrusion by countersunk bolts. By adding wear-resistant blocks, the service life of the plate is improved. The countersunk bolts do not protrude from the wear-resistant blocks, so the steel billet will not be scratched when it impacts the wear-resistant blocks.

[0031] With the stationary beam on the left and the idler roller on the right as a reference, the ear plate of the idler roller is located on the right end face of the idler roller. When the first side is in a horizontal state, the distance between the left end face of the wear-resistant block and the right end face of the stationary beam is less than the distance between the left end face of the ear plate and the right end face of the stationary beam. This prevents the billet from contacting the wear-resistant block due to the excessive step length during the stepping process (under normal circumstances, the billet should step in the middle of the roller table and not contact the wear-resistant block). When the billet slides from the first side face to the roller surface, it detaches from the idler roller.

[0032] Working principle: Steel billets are conveyed forward one by one on the roller conveyor. Initially, the steel billets are on the stationary beam, and the first side is horizontal under the drive of the cylinder. There are no steel billets on the idler roller. The moving beam starts, and the steel billet moves from the moving beam to the idler roller. It slides down to the first side at the end of the stationary beam. The height of the first side is higher than the roller surface of the idler roller. At this time, there is no impact on the roller surface. The moving beam lifts the steel billet again and straightens the steel billet (so that the steel billet is in the middle of the roller conveyor). The cylinder retracts, and the first side rotates around the connecting shaft. It no longer supports the steel billet and the steel billet slides down to the roller surface. The motor of the idler roller starts, and the idler roller conveys the steel billet forward. After the steel billet leaves the roller conveyor, the steel billet support device resets, and the first side remains horizontal.

However, it should be understood that the above description is for illustrative purposes only and does not constitute any limitation on the scope of this utility model. Those skilled in the art can make substitutions or changes to certain features of this utility model without departing from the spirit and scope of this utility model, and such substitutions or changes should be considered to fall within the protection scope of the claims of this utility model.
