Description

Technical Field

[0001] This utility model belongs to the field of early warning technology, and specifically relates to an early warning device for warehouse truck entry and exit. Background Technology

[0002] Significant safety hazards often arise when vehicles enter and exit warehouses during warehouse logistics management. Because pedestrians and vehicles outside the warehouse cannot promptly obtain information about the movement of vehicles inside, especially before a vehicle has fully exited the warehouse door, its dynamic behavior is unpredictable to outsiders, easily leading to collisions, crushing accidents, and other safety incidents. Currently, although some vehicles are equipped with reversing warning devices, their function is mainly limited to reversing situations, and they cannot provide effective advance warning during the driving phase before the rear of the vehicle extends beyond the warehouse door. Therefore, this application designs a warning device for warehouse truck entry and exit. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a warning device for warehouse truck entry and exit. When a vehicle enters the warehouse, when the rear end of the vehicle pushes the push frame backward, the push frame moves, causing the rack to move. The rack moves, causing the gear to rotate. The gear rotates, causing the warning bar to rotate. When the vehicle leaves the warehouse, the push frame is reset by the reset component. The reset push frame moves, causing the rack to move. The rack moves, causing the gear to rotate. The gear rotates, causing the warning bar to rotate in the opposite direction. When the warning bar rotates, it serves to warn pedestrians.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A warning device for warehouse truck entry and exit includes a push frame, a reset component, a gear, a rack, a rotating shaft, a warning rod, and a crossbeam. Two crossbeams are provided, each mounted on one of two opposite walls of the warehouse. The racks are symmetrically arranged on both sides of the push frame and slidably mounted on the crossbeams. A fixed seat is provided on the crossbeam. The gear is fixedly mounted on the rotating shaft, which rotates on the fixed seat. The gear is positioned below the rack, and the rack meshes with the gear. The warning rod is fixedly mounted on the rotating shaft, and its end extends to the outside of the warehouse. The reset component is located on the crossbeam and cooperates with the push frame.

[0006] Preferably, a mounting groove is formed on the crossbeam, and the rack slides in the mounting groove. A guide rail is provided inside the mounting groove, and a sliding groove is formed on the rack. The sliding groove slides in conjunction with the guide rail. The mounting groove not only guides the rack but also protects it, preventing it from tilting or shaking during operation and ensuring the stability of the device during operation.

[0007] Preferably, a clearance groove is also provided at the bottom of the mounting groove on the crossbeam. The clearance groove cooperates with the gear. The clearance groove facilitates the meshing of the rack and the gear, ensuring the normal meshing of the gear and the rack.

[0050] The upright post 201 is designed to limit the sliding rod 103, preventing it from moving too far and affecting the normal operation of the device.

[0051] In this embodiment, as Figure 1 As shown, reflective stickers are also installed on the warning pole 7. The reflective stickers are designed to warn pedestrians and ensure the warning effect of the device on pedestrians.

[0052] Its working process is as follows:

[0053] When a vehicle enters the warehouse, when the rear of the vehicle pushes the pusher 1 to move backward, the pusher 1 moves and drives the rack 3 to move. The rack 3 moves and drives the gear 9 to rotate. The rotation of the gear 9 drives the warning pole 7 to rotate, which serves to warn pedestrians and vehicles. When the front of the vehicle has completely entered the warehouse, the warning pole 7 moves to the top.

[0054] When a vehicle leaves the parking space, the reset component 2 will cause the push frame 1 to reset. The reset of the push frame 1 will cause the rack 3 to move. The movement of the rack 3 will cause the gear 9 to rotate. The rotation of the gear 9 will cause the warning bar 7 to rotate in the opposite direction, which serves as a warning to pedestrians and vehicles.
