Description

Technical Field

[0001] This utility model relates to the field of traffic diversion device technology, and in particular to a traffic diversion device for loading and unloading areas of freight yards. Background Technology

[0002] In the operation of loading and unloading areas in freight yards, traffic flow management is a crucial aspect of ensuring operational safety and efficiency. Loading and unloading areas often involve frequent movement of forklifts, trucks, and other vehicles, as well as overlapping operations between personnel and equipment. Therefore, specialized traffic flow management devices are essential to regulate vehicle traffic, warn surrounding personnel, and prevent collisions caused by obstructed vision or disorderly traffic. Efficient traffic flow management systems are therefore of great importance to the safe operation of loading and unloading areas in freight yards.

[0003] Existing freight yard loading and unloading areas mostly rely on traditional traffic lights or manual traffic control for traffic management, which has significant limitations: traditional traffic lights require fixed waiting cycles, and even if there are no vehicles passing through the loading and unloading area, the signal still needs to be switched at a preset time, which can easily lead to ineffective waiting and cannot adapt to the dynamic changes in vehicle flow during loading and unloading operations; manual traffic control relies on continuous personnel on duty, which not only increases labor costs but also may result in untimely warnings due to human negligence. At the same time, single light warnings are easily overlooked in noisy loading and unloading environments, making it difficult to effectively remind forklift drivers and surrounding personnel, posing a safety hazard. Therefore, we propose a traffic guidance device for freight yard loading and unloading areas to solve this problem. Utility Model Content

[0017] 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 protection scope of the present utility model.

[0018] Please see Figure 1 - Figure 6 The embodiments provided by this utility model are as follows: A traffic diversion device for loading and unloading area of ​​a freight yard includes a first column 1 and a second column 3, wherein a laser emitter 2 and a laser receiver 5 are fixedly installed on the sides of the first column 1 and the second column 3 that are close to each other. A mounting post 4 is provided on one side of the first column 1. Warning lights 11 are fixedly installed on both sides of the mounting post 4. A controller 6 is fixedly installed on one side of the mounting post 4. Two flags 15 are set above the mounting post 4, and a bell 22 is set below the warning light 11 and fixed to the side of the mounting post 4 by a horizontal plate 21. A swing mechanism is installed on the mounting post 4. The swing mechanism is equipped with a striking mechanism. The swing mechanism is installed in conjunction with two flags 15. The striking mechanism is installed in conjunction with a bell 22. The swing mechanism, warning light 11, laser receiver 5, laser emitter 2 and controller 6 are electrically connected.

[0019] like Figure 4 and Figure 5As shown, the swing mechanism includes a motor 7 fixedly installed on the side of the mounting column 4. A rectangular cavity 10 is provided on the mounting column 4. The output shaft of the motor 7 passes through the inner wall of the rectangular cavity 10 and is fixedly installed with a connecting shaft 20. A small gear 19 is fixedly sleeved on the connecting shaft 20. Two upright plates 8 are fixedly installed on the inner bottom wall of the rectangular cavity 10. Rotating holes are provided on the sides of the two upright plates 8 that are close to each other. Rotating shafts 17 are rotatably installed in the two rotating holes. A large gear 18 that meshes with the small gear 19 is fixedly sleeved on the rotating shaft 17. The swing mechanism includes two extrusion columns 13. The ends of the two extrusion columns 13 that are close to each other are fixedly installed on the two ends of the rotating shaft 17. Mounting shafts 12 are fixedly installed on the sides of the two upright plates 8 that are far from each other. Swing rods 16 are rotatably sleeved on the two mounting shafts 12. Extrusion holes 14 are provided on the sides of the two swing rods 16 that are close to each other. The two extrusion columns 13 pass through the two extrusion holes 14 respectively. The two swing rods 16 extend to the outside of the rectangular cavity 10 and are fixedly connected to two flags 15 respectively. The output shaft of motor 7 rotates, causing the connecting shaft 20 to rotate. The connecting shaft 20 rotates, causing the pinion 19 to rotate. The pinion 19 rotates, causing the large gear 18 to rotate. The large gear 18 rotates, causing the rotating shaft 17 to rotate. The rotating shaft 17 rotates, causing the two extrusion columns 13 to rotate. The two extrusion columns 13 rotate and extrude the inner wall of the extrusion hole 14, thereby causing the two swing rods 16 to swing around the two mounting shafts 12, which in turn causes the two flags 15 to swing, thus indicating that a vehicle is approaching.

[0020] like Figure 6 As shown, the striking mechanism includes a turntable 24 fixedly installed at the end of the connecting shaft 20. A sliding hole is provided at the top of the horizontal plate 21, and an L-shaped rod 26 is slidably installed in the sliding hole. An eccentric column 25 is eccentrically installed on the side of the turntable 24. The horizontal bottom of the L-shaped rod 26 contacts the top of the eccentric column 25. A striking ball 23 is fixedly installed on the side of the L-shaped rod 26 through a connecting rod. The striking ball 23 contacts the top of the bell 22. A stop block 28 is fixedly installed at the bottom of the L-shaped rod 26. A spring 27 is sleeved on the L-shaped rod 26. The two ends of the spring 27 are respectively fixedly installed on the sides of the horizontal plate 21 and the stop block 28 that are close to each other. The rotation of the connecting shaft 20 drives the turntable 24 to rotate, which in turn drives the eccentric column 25 to rotate. The rotation of the eccentric column 25 presses the bottom of the L-shaped rod 26, causing the L-shaped rod 26 and the stop block 28 to move upward. The movement of the stop block 28 causes the spring 27 to contract. The movement of the L-shaped rod 26 drives the striking ball 23 to move, and the striking ball 23 separates from the bell 22. When the eccentric column 25 separates from the L-shaped rod 26, the L-shaped rod 26 and the stop block 28 move downward under the action of the spring 27, causing the striking ball 23 to move downward and strike the bell 22, emitting an audible reminder to the forklift driver carrying goods.

[0021] like Figure 6As shown, the horizontal distance between the top of the L-shaped rod 26 and the central axis of the connecting shaft 20 is greater than zero. The advantage of this arrangement is that when the eccentric column 25 rotates, it will first contact the bottom of the L-shaped rod 26 and then separate.

[0022] like Figure 4 As shown, through holes are provided on one inner wall of the rectangular cavity 10 and on the sides of the two vertical plates 8 that are close to each other. One end of the connecting shaft 20 passes through the three through holes in sequence. The through holes are provided to avoid the connecting shaft 20.

[0023] like Figure 4 and 5 As shown, the two extrusion columns 13 are symmetrically arranged about the central axis of the rotation shaft 17, and the angle between them and the central axis of the rotation shaft 17 is 180 degrees. The advantage of this arrangement is that it facilitates the alternating swing of the two swing rods 16.

[0024] like Figure 3 As shown, the inner top wall of the rectangular cavity 10 has two swing holes 9, and two swing rods 16 pass through the two swing holes 9 respectively. The swing holes 9 are designed to avoid the swing rods 16.

[0025] Working principle: The first column 1 and the second column 3 are placed on both sides of the roadside, and the mounting column 4 is placed at the intersection. When a forklift passes between the first column 1 and the second column 3, the laser receiver 5 will not receive the signal from the laser emitter 2. The controller 6 will control the two warning lights 11 to light up and simultaneously control the motor 7 to start. The output shaft of the motor 7 will rotate, driving the connecting shaft 20 to rotate. The connecting shaft 20 will rotate, driving the pinion 19 to rotate. The pinion 19 will rotate, driving the gear 18 to rotate. The gear 18 will rotate, driving the rotating shaft 17 to rotate. The rotating shaft 17 will rotate, driving the two extrusion columns 13 to rotate. The two extrusion columns 13 will rotate, extruding the inner wall of the extrusion hole 14, thereby causing the two swing rods 16 to swing around the two mounting shafts 12, which in turn causes the two flags 15 to swing, thus indicating that a vehicle is approaching. Simultaneously, the rotation of the connecting shaft 20 drives the turntable 24 to rotate, which in turn drives the eccentric column 25 to rotate. The rotation of the eccentric column 25 presses the bottom of the L-shaped rod 26, causing the L-shaped rod 26 and the stop block 28 to move upward. The movement of the stop block 28 causes the spring 27 to contract, and the movement of the L-shaped rod 26 drives the striking ball 23 to move. The striking ball 23 separates from the bell 22. When the eccentric column 25 separates from the L-shaped rod 26, the L-shaped rod 26 and the stop block 28 move downward under the action of the spring 27, causing the striking ball 23 to move downward and strike the bell 22, emitting an audible reminder to the forklift driver carrying goods. When the forklift leaves the first column 1 and the second column 3, the laser receiver 5 can receive the signal from the laser transmitter 2. At this time, the warning light 11 turns off, the two swing arms 16 stop swinging, and the bell 22 stops ringing.

[0026] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
