[0018] The intelligent safety lapping device for cage passengers to enter and exit will be described below with reference to the drawings.

[0019] In the first embodiment of this application, as Figures 1 to 3 shown, the intelligent safety lapping device for cage passengers to enter and exit (hereinafter referred to as "the present invention") includes a fixed base frame 1, a telescopic frame support slide rail 1-1, a telescopic frame control cylinder 1-2, an adaptive pedestrian pedal 2, a pedal body 2-1, a rear lapping plate 2-2, a rear lapping plate control cylinder 2-3, a front lapping plate control cylinder 2-4, a front lapping plate 2-5, a front control cylinder 2-6 for the pedestrian pedal, a rear control cylinder 2-7 for the pedestrian pedal, a cage supporting plate 3, a cage supporting plate body 3-1, a cage supporting plate control machine 3-2, a telescopic frame 4, and a laser ranging camera 5.

The cage supporting plate control machine 3-2 is fixedly installed at the rear of the telescopic frame 4, and the motor of the cage supporting plate control machine 3-2 meshes with the toothed belt at the lower part of the cage supporting plate body 3-1 through a gear; ultrasonic sensors are respectively installed at the front and rear of the adaptive pedestrian pedal 2; a camera is provided on one side of the telescopic frame 4 facing the cage; laser ranging cameras 5 are respectively installed on both sides of the fixed base frame 1 through brackets.

[0020] The sliding type limited angle self-locking locking device and the cage locking device with the utility model bulletin number CN107161819B (hereinafter referred to as "this patent") can adapt to the problem of a large stop tank error range. However, due to the fixed length of the lapping arm, when lapping some cages with a large stop tank error, it cannot adapt to the gap, which will cause a large gap between the lapping arm and the frame body. These gaps not only affect the passage of the material trolley but also pose potential safety hazards. The present invention uses the telescopic front lapping plate 2-5 and the rear lapping plate 2-2 to fill the gaps, can automatically adapt to the height of the cage, and can change the length of the pedal according to needs, effectively preventing gaps from appearing in the front and rear of the lapping plate.

[0021] The structure of the second embodiment is basically the same as that of the first embodiment, except that, as Figure 3 shown, the adaptive pedestrian pedal 2 includes a pedal body 2-1, a rear lapping plate 2-2, a front control cylinder 2-6 for the pedestrian pedal and a rear control cylinder 2-7 for the pedestrian pedal. Grooves are respectively opened at the front and rear of the pedal body 2-1, and the front lapping plate 2-5 and the rear lapping plate 2-2 are slidably installed in the grooves. The control terminals of the front lapping plate 2-5 and the rear lapping plate 2-2 pass through the long rectangular through holes opened on the lower surface of the pedal body 2-1. A protrusion is provided on the lower surface of the pedal body 2-1, and the front lapping plate control cylinder 2-4 and the rear lapping plate control cylinder 2-3 are hinged to the protrusion at the front and rear. The front lapping plate control cylinder 2-4 and the rear lapping plate control cylinder 2-3 are respectively hinged to the control terminals at the lower parts of the front lapping plate 2-5 and the rear lapping plate 2-2. The front control cylinder 2-6 for the pedestrian pedal and the rear control cylinder 2-7 for the pedestrian pedal are respectively hinged to the lower surface of the pedal body 2-1 at the front and rear. The lower ends of the front control cylinder 2-6 for the pedestrian pedal and the rear control cylinder 2-7 for the pedestrian pedal are respectively hinged to the telescopic frame 4. The upper segment spacing of the front control cylinder 2-6 for the pedestrian pedal and the rear control cylinder 2-7 for the pedestrian pedal is large, and the lower segment spacing is small.

[0022] In order to further optimize the working efficiency of the present application and reduce the impact during lapping, rubber layers are provided on the lower surfaces of the front lapping plate 2-5 and the rear lapping plate 2-2. In order to reduce the weight of the equipment, both the adaptive pedestrian pedal 2 and the fixed base frame 1 are frames made of welded steel bars, and steel skins are covered on the upper surfaces of the frames. In order to enable the cage supporting plate 3 to bear the weight and impact of the cage, three concave-shaped brackets are provided on the surface of the telescopic frame 4. Rollers are installed at the upper and lower openings of the concave-shaped brackets through rotating shafts, and the cage supporting plate 3 moves back and forth between the two rollers.

[0023] During use, install the intelligent safety lapping device for cage pedestrian access, connect the corresponding line equipment, and it can be put into use.

[0024] When the present utility model is in use, the specific work is as follows:

[0025] When in use, the tank cage stops at a certain height, and the motor built into the tank support plate control machine 3-2 drives the gear, which drives the tank support plate body 3-1 to extend. At the same time, the telescopic frame control cylinder 1-2 controls the telescopic frame 4 to move forward to a suitable position along the telescopic frame control cylinder 1-2, and then the laser ranging camera 5 and the ultrasonic sensors installed in front and behind the adaptive pedestrian pedal 2 start to work. The laser ranging camera 5 measures the position of the tank cage, and the control machine controls the front control cylinder 2-6 of the pedestrian pedal and the rear control cylinder 2-7 of the pedestrian pedal to extend and retract respectively according to the data. Among them, the front control cylinder 2-6 of the pedestrian pedal extends first, causing the front end of the pedal body 2-1 to tilt up and tilt forward, leaving enough space for the rear end to rise, and then the rear control cylinder 2-7 of the pedestrian pedal The pedal body 2-1 of the adaptive pedestrian pedal 2 is fully extended, and then the front control cylinder 2-6 of the pedestrian pedal and the rear control cylinder 2-7 of the pedestrian pedal are linked to adjust the slope of the pedal body 2-1 according to the height of the tank cage, and make it at the midpoint of the tank cage and the fixed basic frame 1. Then the rear plate control cylinder 2-3 and the front plate control cylinder 2-4 respectively control the rear plate 2-2 and the front plate 2-5 to extend from the pedal body 2-1, and the ultrasonic sensor determines their own position, so that they can be accurately overlapped on the tank cage and the fixed basic frame 1. When overlapping, the front control cylinder 2-6 of the pedestrian pedal and the rear control cylinder 2-7 of the pedestrian pedal need to fine-tune the pedal body 2-1 under the guidance of the laser rangefinder camera 5 to make the overlap more accurate. After the overlap is completed, pedestrians can get on and off, or the staff can load and unload goods.

[0026] In summary, the intelligent safety lap joint device for pedestrian entry and exit of the tank cage of the utility model embodiment controls the lifting and lowering of the pedal body 2-1 through the linkage of the pedestrian pedal front control cylinder 2-6 and the pedestrian pedal rear control cylinder 2-7, and cooperates with the retractable front lap plate 2-5 and the rear lap plate 2-2 to fill the gap, which can automatically adapt to the height of the tank cage and change the pedal length as needed. It can effectively prevent gaps from appearing in front and behind the lap plates, and adapt to the problem of a large error range of the tank cage stop, effectively improving the safety of the tank cage.
