Description

Technical Field

[0001] This invention relates to the field of platform elevators, and more particularly to a material conveying elevator based on an image recognition system. Background Technology

[0002] Precious metal production involves high-temperature smelting and precision machining processes, requiring frequent handling of high-value raw materials, semi-finished products, and finished products. Traditional elevator-style freight elevators, due to their enclosed cabin structure, occupy a large space and have high maintenance costs, making it difficult to meet the requirements for flexibility and safety. In contrast, carless lifting platforms adopt an open design, directly carrying workers and transported precious metal objects via electrically controlled lifting rails. This avoids redundant space occupation by the cabin, making the transfer of precious metal objects more convenient for workers. Therefore, carless lifting platforms, with their safe, efficient, and modular technical characteristics, have become an indispensable vertical logistics solution in precious metal production and storage workshops, meeting the need for convenient management of high-value materials and significantly improving workshop operational efficiency through space optimization. However, carless lifting platforms also currently have many safety hazards. For example, if workers unintentionally lean out of the lifting platform, they are at risk of being pinched by the shaft opening. Furthermore, when foreign objects intrude below the lifting platform or people linger, the descending lifting platform may collide with the foreign objects or people below, creating safety hazards. Summary of the Invention

[0003] To overcome the numerous safety hazards that exist when workers use carless lifting platforms to transport precious metal objects, this invention provides a material conveying elevator based on an image recognition system.

During the lifting process between floors, the electrically controlled lifting guide rail controls the lifting platform. The bottom image recognition module, in conjunction with the top image recognition module, performs image recognition on the shaft openings of each floor's lifting channel to determine if there is any foreign object intrusion. The lifting plate on the side panel controls the buffer ring frame to provide anti-collision protection against foreign objects intruding in the downward direction.

Detailed Implementation

[0017] The embodiments of the present invention will be described below with reference to the accompanying drawings.

[0018] Example 1 The present invention provides a material conveying elevator based on an image recognition system, such as... Figures 1-7As shown, the system includes an electrically controlled lifting guide rail 1, a floor control panel 11, a lifting platform 2, a main control panel 21, a bottom image recognition module 3, side panels 51, a door 52, an electric lifting push rod 53, a lifting plate 71, a baffle 72, an inner pressure spring 73, a pressure sensor 74, and a buffer ring frame 75. The lifting platform 2 is slidably connected to the electrically controlled lifting guide rail 1. Floor control panels 11, corresponding to the number of floors, are installed on the electrically controlled lifting guide rail 1 at corresponding positions on each floor. The floor control panels 11 control the lifting platform 2 to rise and fall to the corresponding floor. The main control panel 21 is installed on the lifting platform 2. A bottom image recognition module 3 for downward monitoring is installed at the bottom of the lifting platform 2. A top image recognition module 4 for downward monitoring is installed at the top of the electrically controlled lifting guide rail 1. A side panel 51 is slidably connected to the left and right sides of the lifting platform 2. The lifting platform 2 is equipped with... There are two electric lifting push rods 53 that control the movement of the two side plates 51 respectively; the telescopic ends of the two electric lifting push rods 53 are respectively fixed to the corresponding side plates 51; a door 52 for entering and exiting the lifting platform 2 is installed between the two side plates 51; a lifting plate 71 is slidably connected to each of the two side plates 51; a baffle 72 is fixed to each of the two lifting plates 71; two internal pressure springs 73 are connected between each of the two baffles 72 and the corresponding side plate 51; two pressure sensors 74 are installed on each of the two side plates 51, and the end of the internal pressure spring 73 connected to the side plate 51 is fixed to the corresponding pressure sensor 74; a U-shaped buffer ring frame 75 is connected to the lower side of each of the two lifting plates 71, and the buffer ring frame 75 is located below the lifting platform 2; the buffer ring frame 75 is composed of a metal frame and buffer cotton surrounding the outside of the metal frame, so that the buffer ring frame 75 not only has the rigid support of the metal frame, but also the soft buffering effect of the buffer cotton.

[0019] like Figure 3 and Figure 5 As shown, a voice alarm module 22 is installed on the main control panel 21; marker lights 6 are installed on the upper surfaces of the two side panels 51 respectively; and marker lights 6 are also installed on the upper surface of the fan door 52.

[0020] like Figure 5 As shown, each of the two side panels 51 is fixed with a handrail 54 on the opposite side. The handrail 54 is located inside the lifting platform 2. After the staff puts their hands on the handrail 54, they will not subconsciously put their hands on the side panel 51 again. This prevents the staff from being injured by the side panel 51 and the shaft opening when the lifting platform 2 passes through the floor shaft opening.

[0021] The working steps of a material conveying elevator based on an image recognition system according to the present invention are as follows.

[0022] The lower side of the lifting platform 2 is initially positioned close to the ground of the bottom floor. At this time, the buffer ring 75 is in close contact with the ground of the bottom floor, and the two baffles 72 are in close contact with the bottom of the corresponding side plates 51. The inner compression spring 73 is compressed by the baffles 72 towards the side plates 51. At the same time, the pressure sensor 74 is in the off state, so the pressure sensor 74 will not monitor the compression state of the inner compression spring 73.

[0023] Workers open door 52 and move the precious metal object onto the lifting platform 2. Then, they operate the main control panel 21 to ascend the lifting platform 2 along the electrically controlled lifting guide rail 1 to the designated floor. During the ascent, the top image recognition module 4 monitors the space between itself and the lifting platform 2. If the top image recognition module 4 detects a partially obstructed area on the marker light 6 on the side panel 51 or the upper surface of door 52, it indicates that a worker on the lifting platform 2 is unconsciously leaning outwards, or that there is unauthorized intrusion of foreign objects, such as illegally placed precious metal objects, into the shaft entrance on a certain floor. At this time, the lifting platform... Platform 2 promptly stops moving upwards to prevent workers from being pinched by the shaft opening or colliding with illegally intruded foreign objects, ensuring worker safety and preventing injury from foreign objects (precious metal semi-finished or finished products), as well as preventing damage to the lifting platform 2 and causing property loss. At the same time, when the top image recognition module 4 detects that the marker light 6 is obstructed, the voice alarm module 22 sounds an alarm, and the electric lifting push rod 53 drives the side plate 51 and its connected fan door 52 to move up and down repeatedly, indicating that workers should move their bodies away from the side plate 51 or fan door 52, or allow other workers to remove and clean up any foreign objects.

[0024] As staff members descend along the electrically controlled lifting rail 1 on the lifting platform 2 using the main control panel 21 on any floor, the bottom image recognition module 3 continuously monitors the space below the lifting platform 2. When the bottom image recognition module 3 detects an unauthorized intrusion of a foreign object at the shaft opening on a certain floor or on the ground of a lower floor, the lifting platform 2 immediately stops moving downwards, and the voice alarm module 22 sounds an alarm, prompting other staff members to remove and clean up the foreign object.

[0025] As staff ride the lifting platform 2 upwards away from the ground floor, the compressed inner spring 73 pushes the baffle 72, causing the lifting plate 71 to move downwards. Simultaneously, the lifting plate 71 pushes the buffer ring frame 75 downwards away from the lifting platform 2. At the same time, the pressure sensor 74 switches to the active state, continuously monitoring the compression state of the inner spring 73. Later, as staff ride the lifting platform 2 downwards, when it approaches a floor shaft opening or the ground of a lower floor, a foreign object suddenly intrudes. This intruding object is located at the bottom edge of the buffer ring frame 75. The buffer ring frame 75 will collide with the intruding object before the lifting platform 2. Because the buffer ring frame 75 has a softer cushioning effect compared to the lifting platform 2, it significantly reduces the impact. The impact force generated by the collision of the ring frame 75 with the intruding foreign object is simultaneously pushed by the intruding foreign object to move the lifting plate 71 upward along the side plate 51. At the same time, the baffle 72 on the lifting plate 71 drives the inner pressure spring 73 to squeeze the pressure sensor 74 upward. After the pressure sensor 74 is triggered, the lifting platform 2 stops moving downward immediately. During this process, because the buffer ring frame 75 has an upward movement avoidance space, when the buffer ring frame 75 collides with the foreign object and performs the above-mentioned upward movement avoidance work, the collision impact force generated by the buffer ring frame 75 on the foreign object is much smaller than that generated by the lifting platform 2 on the foreign object when the lifting platform 2 directly collides with the foreign object without avoidance space. This protects the lifting platform 2 and the precious metal.

[0026] Example 2 like Figures 1-7 As shown in Embodiment 1, this embodiment has a floor lighting lamp 12 corresponding to the number of floors installed on the front side of the electrically controlled lifting guide rail 1. The floor lighting lamp 12 is aligned with the shaft opening of the corresponding floor. The floor lighting lamp 12 illuminates the shaft opening of the corresponding floor, which not only reminds passersby that there is an unfenced shaft opening in the area, but also allows the top image recognition module 4 to clearly identify whether there are any foreign objects illegally intruding into the shaft opening of each floor in the dark environment, especially illegally placed precious metal objects, ensuring that the lifting platform 2 and the staff will not collide with foreign objects intruding into the shaft opening in the dark environment. The lifting platform 2 is equipped with a platform lighting lamp 23 to illuminate the entire lifting platform 2. When the lifting platform 2 moves upward, when the lifting platform 2 blocks the floor lighting lamp 12 aligned with the shaft opening above, the platform lighting lamp 23 replaces the floor lighting lamp 12 to illuminate the shaft opening of that floor, allowing the staff to clearly notice and avoid the gap between the lifting platform 2 and the shaft opening.

[0027] Example 3 like Figures 1-7As shown, based on Embodiment 1, the buffer ring frame 75 of this embodiment consists of a fixed C-shaped frame 751, a movable C-shaped frame 752, an external pressure spring 753, and rollers 77; the fixed C-shaped frame 751 is rotatably connected between the front sides of the two lifting plates 71; the movable C-shaped frame 752 is slidably connected to the rear side of the fixed C-shaped frame 751, and the movable C-shaped frame 752 and the fixed C-shaped frame 751 together form a telescopic U-shaped structure; two external pressure springs 753 are fixedly connected between the fixed C-shaped frame 751 and the movable C-shaped frame 752; a rotary driver 76 for driving the fixed C-shaped frame 751 to rotate is installed on the left lifting plate 71; several rollers 77 are rotatably connected to the side of the movable C-shaped frame 752 away from the fixed C-shaped frame 751; four exhaust fans 8 are installed at the bottom of the lifting platform 2, and the bottom image recognition module 3 is surrounded in the middle of the four exhaust fans 8; an air outlet 201 connecting all the exhaust fans 8 is opened on the left and right sides of the lifting platform 2.

[0028] As the lifting platform 2 moves downward along the electrically controlled lifting guide rail 1, if the bottom image recognition module 3 detects an unauthorized intrusion of a foreign object at the shaft opening of a certain floor or on the ground of a lower floor, as the lifting platform 2 moves downward, when the lower side of the lifting platform 2 approaches the foreign object, the rotary drive 76 drives the fixed C-shaped frame 751 and its connected movable C-shaped frame 752 to sweep from back to front across the area below the lifting platform 2. The movable C-shaped frame 752 pushes the foreign object blocking the area below the lifting platform 2 away from the shaft opening, so that there is no longer any foreign object blocking the area below the lifting platform 2. This ensures that the lifting platform 2 can descend safely and smoothly, and there is no need for staff to remove and clean the foreign object after the lifting platform 2 stops.

[0029] If a foreign object suddenly intrudes during the downward movement of the lifting platform 2 along the electrically controlled lifting guide rail 1, that is, when the pressure sensor 74 and the inner pressure spring 73 detect that there is a foreign object blocking the bottom of the buffer ring frame 75, the rotary driver 76 can also drive the fixed C-shaped frame 751 and its connected movable C-shaped frame 752 to sweep from back to front under the lifting platform 2, and the movable C-shaped frame 752 will push away the foreign object blocking the bottom of the lifting platform 2.

[0030] As the lifting platform 2 moves downward along the electrically controlled lifting guide rail 1 to a position close to the ground of the lower floor, and the rotary drive 76 drives the fixed C-shaped frame 751 and its connected movable C-shaped frame 752 to sweep from back to front under the lifting platform 2 to push the foreign object away, when the overall height of the foreign object is relatively low, the lifting platform 2 is relatively close to the ground, so that the rollers 77 on the movable C-shaped frame 752 can contact the ground. The movable C-shaped frame 752, which is sweeping forward, is blocked by the ground through the rollers 77, causing the external pressure spring 753 to compress towards the fixed C-shaped frame 751. However, since the compression amount of the movable C-shaped frame 752 within the fixed C-shaped frame 751 is limited, the electric lifting push rod 53 drives the side plate 51 and its connected lifting plate 71 and buffer ring frame 75 to rise as a whole, increasing the overall height of the buffer ring frame 75. This allows the movable C-shaped frame 752 to smoothly push away the foreign object with a relatively low overall height while reducing the required compression amount.

[0031] In addition, during the process of the movable C-shaped frame 752 moving forward along the ground through the rollers 77 to push away foreign objects, the electric lifting push rod 53 drives the side plate 51 and its connected lifting plate 71 and buffer ring frame 75 to rise as a whole, replacing the lifting platform 2 driving the buffer ring frame 75 to rise. This can avoid the discomfort caused to the staff by the lifting platform 2 frequently switching the direction of up and down movement. During this period, the rollers 77 will replace the movable C-shaped frame 752 to move forward along the ground, avoiding the movable C-shaped frame 752 directly rubbing against the dust on the ground and generating a lot of dust and harsh noise.

[0032] However, when the movable C-shaped frame 752 pushes the foreign object forward, the foreign object will inevitably rub against the dust on the ground, generating a large amount of dust. At this time, four exhaust fans 8 promptly remove the dust that is drifting towards the bottom image recognition module 3. The removed dust is discharged to the left and right sides from the two air outlets 201, preventing the drifting dust from covering the bottom image recognition module 3 and obstructing its monitoring view, thus ensuring that the bottom image recognition module 3 can work continuously and stably.

[0033] The above embodiments are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Therefore, all equivalent changes made to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
