Description

Technical Field

[0001] This application is applied to the field of automated conveying, and specifically relates to a heavy-duty stop device and a conveyor line including the same. Background Technology

[0002] In the prior art, a stop device is installed on the conveyor line to stop the load at a preset position, and to perform operations and processing on the load at the preset position. Afterwards, the load can be released to continue running on the conveyor line. In some heavy-load working conditions, the heavy load will cause a large impact on the stop device. The stop device subjected to the impact force will transmit the impact force to the conveyor line, causing the conveyor line to vibrate. At the same time, the connection between the stop device and the conveyor line will be affected, and the life of the stop device itself will be shortened. Summary of the Invention

[0003] In view of the above reasons, this application discloses a heavy-duty stopping device, including a fixed bracket, a stopping plate, a stopping frame, a connecting rod, and a driving mechanism. The driving mechanism drives the first end of the stopping frame to move horizontally back and forth on the fixed bracket. The stopping plate is fixedly mounted on the second end of the stopping frame. The middle section of the stopping frame is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the fixed bracket. The vertical height of the stopping plate changes with the position of the first end of the stopping frame. When the position of the first end of the stopping frame is close to the hinge end of the connecting rod and the fixed bracket, the stopping surface of the stopping plate is vertical and at its highest position. When the position of the first end of the stopping frame is far away from the hinge end of the connecting rod and the fixed bracket, the stopping surface of the stopping plate is inclined and at its lowest position.

[0004] Preferably, the driving mechanism drives the hinge plate to move horizontally back and forth on the fixed bracket, and the hinge plate is hinged to the first end of the stop frame.

[0005] Preferably, the driving mechanism includes a motor, a chain, a drive wheel, a driven wheel, and a connecting block. The motor is mounted on the fixed bracket. The drive wheel is located on one side of the fixed bracket, and the transmission wheel is located on the other side. The chain is sleeved between the drive wheel and the transmission wheel. The beginning and end of the chain are connected by the connecting block, which is fixedly connected to the hinge plate. The motor drives the drive wheel to rotate. By rotating the motor in both directions, the hinge plate is driven to move horizontally back and forth on the fixed bracket.

[0006] Preferably, the upper end of the fixed bracket is provided with a linear slide rail, the lower end of the hinge plate is provided with a slider, and the linear slide rail and the slider are connected in cooperation.

[0007] Preferably, the lower end of the fixed bracket is provided with an adjustable support foot, and the height of the fixed bracket can be adjusted by adjusting the adjustable support foot.

[0008] Preferably, the upper end of the fixed bracket is provided with a profile connecting plate, which is used to connect with the conveyor.

[0009] This application also discloses a conveyor line, including a chain conveyor and a heavy-duty stop device as described above. The upper end of the fixed bracket of the heavy-duty stop device is fixedly connected to the chain conveyor, and the lower end of the fixed bracket is fixedly connected to the ground. The stop plate is located between the conveying profiles on both sides of the chain conveyor. When the stop plate is in the highest position, the height of the stop surface is higher than the conveying plane of the chain conveyor. When the stop plate is in the lowest position, the height of the stop surface is lower than the conveying plane of the chain conveyor.

[0010] The advantage of this application is that the stop frame is moved by the drive mechanism, thereby changing the height and position of the stop plate, thus completing the switching between the stop and release states. The stop plate is connected to the ground by a fixed bracket and adopts a triangular hinge connection structure, which has high structural strength and can withstand high impact force without impacting the conveyor. It can also be connected to any position on the conveyor and is suitable for heavy-duty working conditions.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] like Figures 1 to 3As shown, the fixed bracket 1 is an aluminum profile metal bracket with a stable structure consisting of four legs and a support beam. The drive mechanism is located on the fixed bracket 1. The drive mechanism can drive the first end of the stop frame 2 to move horizontally back and forth on the upper surface of the fixed bracket 1. The second end of the stop frame 2 is fixedly equipped with a stop plate 3. The stop frame 2 is a metal obtuse-angle bent piece. The first end and the second end of the stop frame 2 are the opposite head and tail ends. The stop plate 3 is a metal rectangular plate. One end of the stop plate 3 facing outward is the stop surface 301, which is a plane used to contact the load for stopping. The middle section of the stop frame 2 is hinged to one end of the connecting rod 4. The middle section can be the bending angle position of the stop frame 2. The other end of the connecting rod 4 is hinged to one side of the fixed bracket 1. The connecting rod 4, the stop frame 2, and the fixed bracket 1 form a triangular structure. The position and height of the stop plate 3 will change with the position of the first end of the stop frame 2. When in the stopping state... When the vehicle is in the free-moving state, the first end of the stop frame 2 is moved to the first position on the fixed support 1 under the drive mechanism. The first position is when the first end of the stop frame 2 is close to the hinge position between the connecting rod 4 and the fixed support 1. At this time, the first end of the stop frame 2 is closest to the hinge position between the connecting rod 4 and the fixed support 1. The second end of the stop frame 2, that is, the stop plate 3, is at the highest position, and the stop surface 301 is in a vertical state. The stop surface 301 can block the load. When the vehicle is in the free-moving state, the first end of the stop frame 2 is moved to the second position on the fixed support 1 under the drive mechanism. The second position is when the first end of the stop frame 2 is far away from the hinge position between the connecting rod 4 and the fixed support 1. At this time, the first end of the stop frame 2 is farthest from the hinge position between the connecting rod 4 and the fixed support 1. The second end of the stop frame 2, that is, the stop plate 3, is at the lowest position, and the stop surface 301 is in an inclined state. The stop plate 3 does not interfere with the running trajectory of the load.

[0021] In some implementations, such as Figures 1 to 3 As shown, the drive mechanism drives the hinge plate 5 to move horizontally back and forth on the fixed bracket 1. The hinge plate 5 is a strip plate with lugs for hinged connection. The first end of the stop frame 2 is hinged to the lugs on the upper surface of the hinge plate 5. Multiple lugs can be provided on the hinge plate 5, and multiple sets of stop frames 2 can be hinged to simultaneously. Multiple stop plates 3 can be set through multiple sets of stop frames 2 to complete the stopping or release at multiple positions.

[0022] In some implementations, such as Figures 1 to 3As shown, the drive mechanism includes a motor 6, a chain 7, a drive wheel 8, a driven wheel 9, and a connecting block 10. The motor 6 is fixedly mounted on a fixed bracket 1. The fixed bracket 1 has a drive wheel 8 on one side and a driven wheel 9 on the other side. The chain 7 is sleeved between the drive wheel 8 and the driven wheel 9. The two ends of the chain 7 are connected by the connecting block 10 to form a chain. The motor 6 can drive the drive wheel 8 to rotate, thereby causing the chain 7 to rotate around the drive wheel 8 and the driven wheel 9. The upper surface of the connecting block 10 is fixedly connected to the lower surface of the hinge plate 5. By rotating the motor 6 forward and backward, the hinge plate 5 can be moved horizontally back and forth on the fixed bracket 1. That is, the position of the hinge plate 5 is controlled by the motor 6, thereby controlling the position and height of the stop plate 3.

[0023] In some implementations, such as Figures 1 to 3 As shown, a linear slide rail 11 is provided at the upper end of the fixed bracket 1. The direction of the linear slide rail 11 is the same as the rotation direction of the chain 7. A slider 12 is provided at the corresponding position at the lower end of the hinge plate 5. The linear slide rail 11 and the slider 12 are connected in a sliding fit to reduce the friction during the translation process of the hinge plate 5, and at the same time play a guiding role.

[0024] In some implementations, such as Figures 1 to 3 The fixed bracket 1 is provided with an adjustable support foot 13 at the lower end. The height of the adjustable support foot 13 can be adjusted by rotating the bottom. By adjusting the adjustable support foot 13, the height of the fixed bracket 1 can be adjusted, thereby adjusting the highest and lowest positions of the stop plate 3 to adapt to more working conditions.

[0025] In some implementations, such as Figures 1 to 3 As shown, profile connecting plates 14 are provided at the four top corners of the upper end of the fixed bracket 1. The profile connecting plates 14 are provided with preset holes. The profile connecting plates 14 can be used to connect with the conveyor. Because of the preset holes, they can be directly and detachably connected to the conveyor by bolts, which is convenient for disassembly and assembly, and can be set in any position.

[0026] like Figure 4 And reference Figures 1 to 3As shown, the upper end of the fixed bracket 1 is fixedly connected to the chain conveyor 15 through the profile connecting plate 14, and the lower end of the fixed bracket 1 is connected to the ground through the adjustable support leg 13. The position of the stop plate 3 is located between the conveying profiles on both sides of the chain conveyor 15. When the load is placed on the chain conveyor 15, when it is necessary to stop the load, the drive mechanism drives the stop plate 3 to the highest position. At this time, the stop surface 301 is vertical and its height is higher than the conveying plane of the chain conveyor 15. The stop plate 3 blocks the movement of the load on the chain conveyor 15. When it is necessary to release the load, the drive mechanism drives the stop plate 3 to the lowest position. At this time, the stop surface 301 is inclined and its height is lower than the conveying plane of the chain conveyor 15. The stop plate 3 does not interfere with the movement of the load on the chain conveyor 15. The load passes the position of the stop plate 3 and continues to move along the chain conveyor 15.
