[0035] Embodiment:
[0036] The embodiment of the present application discloses a cargo elevator anti-collision limiting system device, which solves the problem that goods are easy to hit the hall car door and the inner wall of the car when entering the elevator. In addition, it also solves the problem that goods are not placed in the center, which is easy to cause goods to fall or be biased, resulting in damage to the elevator. In order to overcome these problems, a cargo elevator anti-collision limiting system device is provided.
[0037] Reference Figure 1As shown, the cargo elevator anti-collision limiting system device includes an elevator car 1 and a preliminary area 2 of the elevator hall door entrance, an anti-collision protection plate 3 is arranged in the elevator car 1, and an anti-collision limiting device is arranged in the preliminary area 2. The anti-collision limiting device includes a monitoring radar 51 at the hall door entrance, an identification camera 52, and a buffer pile 6. The monitoring radar 51 is integrated on the buffer pile 6. The buffer pile 6 is provided with a plurality of buffer piles and forms a limiting detection area for the orderly entry of goods into the car. The buffer pile 6 can limit the goods and also has a lifting mechanism 8 to drive the lifting action, so as to prevent oversized goods from entering the car and play a blocking role. The limiting detection area is in the preliminary area 2, and the identification camera 52 identifies the goods passing through the limiting detection area.
[0038] The main function of the monitoring radar 51 is to detect and locate objects using radio waves. It works by emitting electromagnetic waves and receiving the signals reflected back from the target objects. The emitted signals reflect back when encountering objects, and the receiver calculates the distance, speed, and direction information of the objects based on the time and frequency changes of the reflected signals. In this scheme, the existing monitoring radar 51 module is used to collect the speed, direction, and distance data of the goods transportation.
[0039] In this scheme, the identification camera 52 mainly captures and records images or videos to realize the identification, tracking, and monitoring of target objects. These cameras are usually equipped with image processing and identification technology, which can automatically analyze image content, extract key information, and make corresponding responses.
[0040] The identification camera 52 has intelligent identification function and can automatically detect, identify, and classify objects, faces, license plates, and other key information in images. Based on existing technology, this camera has wide application in security, traffic management, and other fields. In this scheme, it is applied to the elevator control panel of the elevator to identify and collect image information of goods.
[0041] The identification camera 52 can monitor the target area in real time, capture abnormal situations in time, and issue alarms or notifications to relevant personnel for processing. This real-time monitoring capability helps to improve security and reduce potential safety hazards.

[0046] The system device first identifies and scans the goods before the goods enter the elevator car 1. The monitoring radar 51, the identification camera 52, and the measuring light eye 53 detect the goods in multiple aspects to form collected data for processing by the processor, so that the information of the goods can be comprehensively collected, and the elevator can be prevented from being damaged by overloading or oversized goods. After the goods enter the elevator car 1, the anti-collision protection plate 3 in the elevator car 1 can also be synchronously actuated to adjust the position of the goods.
[0047] Based on the above scheme, the buffer pile 6 is provided below with a lifting mechanism 8 for driving the lifting action of the buffer pile 6. The lifting mechanism 8 can be a pneumatic cylinder, or a gear and rack lifting drive structure, or a screw rod lifting mechanism 8.
[0048] The operation process of the anti-collision limiting system device is as follows:
[0049] S1: The goods stop in front of the buffer pile 6 at the hall door, the delivery personnel manually call the elevator, the hall door measuring light eye 53 measures the size of the goods, and the elevator responds to the instruction to reach the designated floor and fully open the elevator door.
[0050] S2: When the elevator door is fully opened, the hall door monitoring radar 51 determines that the goods are completely stationary, the hall door identification camera 52 on the elevator outside call plate confirms that the delivery personnel is an authorized person, the hall door buffer pile 6 is lowered, and the anti-collision protection plate 3 in the car is extended according to the size of the goods.
[0051] S3: The personnel push the goods into the car interior and fix the goods within the range circled by the anti-collision protection plate 3 in the car to ensure that the goods are located at the center position of the car.
[0052] S4: The personnel register the selected floor instruction, the elevator door is closed, the hall door buffer pile 6 is raised, and the elevator can normally operate to the destination floor.
[0053] Reference Figure 2This solution also includes a transport trolley 9. The transport trolley 9 includes a frame, four casters 92, a main drive mechanism 93, and a placement plate 94. The placement plate 94 is used to place goods. The frame includes a main frame 911 and a sub-frame 912, which are slidably assembled with each other. The sub-frame 912 is located below the main frame 911. Casters 92 are installed on both sides of the front end of the main frame 911 and on both sides of the rear end of the sub-frame 912. The main drive mechanism 93 is installed at the front end of the sub-frame 912, and when the sub-frame 912 is stored under the main frame 911, the main drive mechanism 93 is located in the middle of the main frame 911.
[0054] Multiple battery packs 95 are also fixed on the sub-frame 912. The battery packs 95 supply power to the main drive mechanism 93. The main drive mechanism 93 includes a motion controller and drive wheels 931, which are located on both sides of the sub-frame 912.
[0055] refer to Figure 2 ,、 Figure 3 , Figure 4 and Figure 5 As shown, the main frame 911 is provided with a horizontal slide groove 100, and the secondary frame 912 is provided with a slider 110 that slides in conjunction with the slide groove 100. The slide groove 100 is provided with a positioning lock hole 120, and the slider 110 is provided with an electronic locking pin 130 for fixing in conjunction with the lock hole. When the electronic locking pin 130 is powered on, it releases the locking engagement with the lock hole, and when the power is off, it completes the locking engagement with the lock hole.
[0056] exist Figure 3 and Figure 4 In the electronic lock pin 130, there are an electromagnetic coil part 131, a mounting bracket 132, and a movable pin 133. The electromagnetic coil part 131 is fixed on the mounting bracket 132, and the movable pin 133 is located in the middle of the electromagnetic coil part 131 and is driven by the electromagnetic coil part 131 to perform extension and retraction. The movable pin 133 also extends out of the mounting bracket 132 to cooperate with the lock hole for locking engagement.
[0057] The transport trolley 9 is used in conjunction with the elevator to transport goods, thereby improving the efficiency and convenience of goods transportation. The transport trolley 9 can be adjusted in terms of its extension length according to the elevator situation. Here, the extension means that the main frame 911 and the sub-frame 912 can slide relative to each other, thereby improving the reliability of the trolley transportation process.
[0058] The main driving mechanism 93 is powered by the battery pack 95, so that it can work more durable. The electronic lock pin 130 can realize the locking operation between the main frame 911 and the auxiliary frame 912. If it is necessary to adjust the length between the main frame 911 and the auxiliary frame 912, the slider 110 can be relied on to slide, and then the electronic lock pin 130 is used to fix the lock. The transport trolley 9 which can be extended and retracted cooperates with the elevator car 1 to load the goods, so that the wheels can enter more reliably, and then the goods are sent into the elevator car 1. When the goods are carried out of the car, the goods can be partially moved out of the elevator car 1 first, at this time the wheel support is more stable, and the transport of goods is more stable and reliable.

Any person skilled in the art can modify or change the above embodiments without departing from the spirit and scope of the present application. Therefore, any equivalent changes made according to the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
