[0033] The utility model discloses an automatic lifting guardrail 30, which includes an operating table 10, a lifting component, a guardrail 30 and a detection component 40. A parking space is arranged on one side of the operating table 10; the lifting component is arranged between the operating table 10 and the parking space; the guardrail 30 can be lifted and lowered on the lifting component, and the lifting component is used to drive the lifting component to rise above the table top of the operating table 10, or drive the guardrail 30 to descend below the table top of the operating table 10; the detection component 40 is arranged above the lifting component, the detection component 40 is electrically connected to the lifting component, and the detection direction of the detection component 40 is toward the parking space.
[0034] In one embodiment, please refer to Figure 1 The top surface of the operating platform 10 is a plane, which is used for operators to walk or drive special equipment such as forklifts.
[0035] A parking space is provided on one side of the operating platform 10 for parking vehicles such as trucks. After the vehicle is parked, for example, a door panel of the vehicle compartment is overlapped on the operating platform 10 as a temporary operating surface for loading and unloading operations.
[0036] The other side of the operating platform 10 is used to dock with the warehouse, and a fast door 60 is provided between the operating platform 10 and the warehouse. The guardrail 30 is installed between the operating platform 10 and the parking space, and the position of the operating platform 10 corresponds to the position of the fast door 60, or the length of the guardrail 30 corresponds to the length of the operating platform 10, that is, the edge of the entire operating platform 10 is enclosed.
[0037] After the vehicle enters the parking space, the detection component 40 is used to detect and determine whether the vehicle is parked in place. The detection component 40 is electrically connected to the lifting component, and can be automatically controlled by, for example, a PLC controller. The detection component 40 sends a detection signal to the controller, and the controller controls the lifting component to raise or lower the guardrail 30 according to the detection signal.
[0038] For example, when the detection component 40 detects that the vehicle has moved to the parking space, it sends a high-level detection signal indicating that the vehicle has arrived to the controller, and the controller controls the lifting component to lower the guardrail 30 to connect the vehicle and the operating platform 10. On the contrary, a low-level signal indicating that the vehicle has not been detected is sent to the controller, and the controller controls the lifting component to raise the guardrail 30 to isolate the operating platform 10 to prevent the operator or equipment such as a forklift from falling.
[0039] When the guardrail 30 is raised, the bottom of the guardrail 30 is flush with the table surface of the operating platform 10, thereby ensuring the isolation effect. When the guardrail 30 is lowered, the top of the guardrail 30 is flush with the table surface of the operating platform 10, thereby ensuring the connection between the vehicle and the operating platform 10.
[0040] The height of the guardrail 30 can be adjusted according to the operation requirements, and is usually set between 1m and 1.5m to prevent the risk of operators or equipment such as forklifts falling.
[0041] The technical solution of the utility model detects whether the vehicle enters the parking space through the detection component 40 to ensure that the vehicle is parked in place. When the vehicle is parked in place, the lifting component controls the guardrail 30 to descend so that the vehicle can dock with the operating platform 10, which is convenient for operators to perform loading and unloading operations. When the loading and unloading is completed, the detection component 40 detects whether the parking space is vacant to ensure that the vehicle leaves. When the vehicle leaves the parking space, the lifting component controls the guardrail 30 to rise, blocking the edge of the operating platform 10 to prevent the operator or the vehicle from falling from the operating platform 10, thereby improving the safety during the loading and unloading process.
[0042] In one embodiment, please refer to Figure 1 and Figure 2 The lifting assembly includes a driving member and two lifting rods 20 arranged opposite to each other, and the two ends of the guardrail 30 are respectively connected to the two lifting rods 20; the driving member is connected to the guardrail 30, and the driving member is used to drive the guardrail 30 to move up and down on the lifting rods 20.
[0043] The positions of the two lifting rods 20 correspond to the positions on both sides of the fast door 60 , or they can also be arranged on both sides of the operating platform 10 .
[0044] The two ends of the guardrail 30 are respectively engaged in the lifting rod 20. Specifically, the lifting rod 20 has a slide groove 21, and the two ends of the guardrail 30 are respectively engaged in the slide groove 21.
[0045] The driving member is a cylinder or a linear module. The driving end of the driving member is directly connected to the guardrail 30, so as to drive the guardrail 30 to move along the extension direction of the slide 21, play a role in limiting the guardrail 30, and avoid the guardrail 30 from being offset during the lifting process.
[0046] The lifting assembly further includes a protective cover, which is disposed around the lifting rod 20. The protective cover can be made of metal material or made of corrosion-resistant and hard plastic, thereby protecting the lifting rod 20 and improving the service life of the lifting rod 20.
[0047] In one embodiment, please refer to Figure 2 The detection component 40 includes a camera 41 and a sensor 42. The camera 41 is arranged above the operating table 10, and the shooting direction of the camera 41 is toward the parking space; the sensor 42 is arranged at the bottom of the guardrail 30, and the detection direction of the sensor 42 is toward the parking space.
[0048] The camera 41 is used to monitor and record the loading and unloading process, so that the operator can trace back the loading and unloading process. In addition, the automatic lifting guardrail 30 also includes a display screen, which is arranged on the operating platform 10 and is electrically connected to the camera 41.
[0049] The images captured by the camera 41 can be displayed on the display screen in real time. The display screen can be installed in the warehouse so that the operators in the warehouse can view and realize rapid interaction with the operators who are loading and unloading materials.
[0050] In one embodiment, the distance sensor may be directly installed above the operating platform 10, such as the top of the fast door 60, so as to expand the detection range and improve the detection effect.
[0051] In addition, please refer to Figure 3 The sensing element 42 can be a distance sensor installed at the bottom of the guardrail 30. When the vehicle does not enter the parking space, the guardrail 30 rises, and the bottom of the guardrail 30 is flush with the surface of the operating table 10, which is convenient for the distance sensor to detect. When the vehicle enters the parking space, it gradually approaches the distance sensor, so that the vehicle can be judged whether it is parked in place according to the vehicle distance, thereby improving the detection accuracy.
[0052] In one embodiment, the automatic lifting guardrail 30 further includes a fence 50 , and the fence 50 is disposed on the table surface of the operating table 10 , and the fence 50 is staggered with the guardrail 30 .
[0053] In order to improve flexibility, during the loading and unloading process, it is only necessary to ensure that the vehicle compartment is docked with the operating platform 10. Fences 50 can be set at other positions of the operating platform 10 for isolation and protection, thereby further improving safety performance.
[0054] Therefore, the position of the guardrail 30 corresponds to the position of the fast door 60. The fence 50 is installed at the edge of the operating platform 10 and is offset from the guardrail 30 to prevent interference between the guardrail 30 and the vehicle after it is lowered.
[0055] There are two fences 50, and the two fences 50 are located on both sides of the guardrail 30. Thus, both sides of the guardrail 30 are isolated and protected at the same time.
[0056] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
