[0007] Preferably, a first hydraulic push rod is fixed to the left side of the support plate, the first hydraulic push rod is electrically connected to the PLC controller, and one end of the telescopic rod of the first hydraulic push rod is fixedly connected to the bottom surface of the adjustment plate.

[0008] Preferably, a laser displacement sensor is fixed to the right side of the support plate, and the laser displacement sensor is electrically connected to the PLC controller.

[0009] Preferably, the front and rear sides of the inner wall of the movable groove are respectively provided with sliding grooves, the front and rear sides of the adjustment plate are respectively fixed with sliders, and the two sliders are respectively slidably arranged in the two sliding grooves.

[0014] Compared with the prior art, the automatic lifting platform for cameras using the above technical solution has the following beneficial effects:

[0015] 1. During use, the adjusting plate, the first driving motor, the rotating shaft, the upper pulley, the lower pulley, the belt body, and the lifting plate are used to realize the automatic lifting and lowering adjustment of the camera body. At the same time, through the use of the limiting column, the U-shaped seat, and the rubber roller, the shaking of the camera body during lifting and lowering can be reduced, which is conducive to improving the stability of the camera body during lifting and lowering, thereby improving the shooting stability, thereby improving the clarity of the camera body shooting;

[0016] 2. During use, when the vibration amplitude of the belt body is too large, the adjustment plate can be raised and lowered by starting the first hydraulic push rod, thereby driving the upper pulley to raise and lower and adjust the tension of the belt body, effectively reducing the impact of the vibration of the belt body on the shooting stability, and further reducing the shaking of the camera body when it is raised and lowered. The laser displacement sensor uses a laser beam to illuminate the surface of the belt body, and by measuring the changes in the reflected light of the laser beam on the surface of the belt body, the displacement and vibration of the belt body can be accurately measured. When the vibration amplitude of the belt body is too large, the information is transmitted to the PLC controller, and the first hydraulic push rod is started to raise and lower the adjustment plate, thereby automatically adjusting the tension of the belt body;

[0017] 3. During use, the slide groove and the slider are used to limit the adjustment plate, prevent the adjustment plate from shifting, improve the stability of the adjustment plate when it is raised or lowered, improve the stability of the entire device, and form a stable guiding effect. The bearing and the support shaft are used to support the lower pulley. The use of bearings reduces the friction resistance when the lower pulley rotates, making it rotate more smoothly. The bearings can withstand large loads and speed changes, effectively reducing the wear between the lower pulley and the support shaft, improving the durability of the lower pulley, and extending the service life of the equipment. When it is necessary to adjust the shooting angle of the camera body, start the second drive motor to rotate it, thereby driving the U-shaped box and the internal camera body to rotate and adjust, realizing the multi-angle shooting function of the camera body and improving the flexibility and diversity of shooting;

[0018] Fourth, in use, the disassembly and assembly process of the camera body is simplified, the work efficiency is improved, and the camera body is stably fixed through the clamping action of the second hydraulic push rod, ensuring the stability during shooting. When the second hydraulic push rod clamps the U-shaped box, the rubber pad first contacts the U-shaped box and produces a certain compression deformation. This compression deformation not only enhances the stability of the clamping but also plays a certain buffering role, reducing the impact and wear of the second hydraulic push rod on the U-shaped box and the internal camera body, while increasing the friction between the clamping surface and the U-shaped box to improve the stability of the clamping.

DETAILED DESCRIPTION

[0028] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1-Figure 8 As shown, an automatic lifting platform for a camera includes a bottom plate 1, which is arranged below a camera body 2, a support plate 3 is fixed to the top surface of the bottom plate 1, a PLC controller is fixed to the top surface of the bottom plate 1, the model of the PLC controller may be S7-1200, the camera body 2 is electrically connected to the PLC controller, a movable groove 4 is provided on the top surface of the support plate 3, an adjustment plate 5 is movably provided inside the movable groove 4, a rotating hole 6 is provided on the right side of the adjustment plate 5, a first driving motor 7 is fixed to the left side of the adjustment plate 5, the first driving motor 7 is electrically connected to the PLC controller, a rotating shaft 8 is fixed to the output shaft of the first driving motor 7, an upper pulley 9 is fixed to the right end of the rotating shaft 8, a lower pulley 10 is rotatably provided on the right side of the support plate 3, and the lower pulley 10 A belt body 11 is arranged between the upper pulley 9, a fixing plate 12 is fixed to the right side of the support plate 3, a limiting column 13 is fixed between the fixing plate 12 and the bottom plate 1, a lifting plate 14 is movably arranged on the outer wall of the limiting column 13, a limiting hole 15 is arranged on the top surface of the lifting plate 14, the limiting column 13 is arranged in the limiting hole 15, two U-shaped seats 16 are fixed on the top and bottom surfaces of the lifting plate 14, rubber rollers 17 are rotatably arranged inside the two U-shaped seats 16, and the two rubber rollers 17 are respectively in contact with the limiting column 13, a fixing hole 18 is arranged on the top surface of the lifting plate 14, and the fixing hole 18 is fixedly connected to the belt body 11, a U-shaped box 19 is rotatably arranged above the lifting plate 14, and the camera body 2 is detachably arranged in the U-shaped box 19.

[0030] During use, the staff takes pictures through the camera body 2. When the position of the object changes, the camera body 2 recognizes this change through its built-in automatic recognition and tracking system, and sends a signal to the PLC controller. After receiving the signal, the PLC controller immediately starts the first drive motor 7. The first drive motor 7 drives the rotating shaft 8 to rotate, and then drives the upper pulley 9 connected to it to rotate. The upper pulley 9 transmits power to the lower pulley 10 through the belt body 11, forming a continuous transmission system. The movement of the belt body 11 drives the lifting plate 14 fixedly connected to it to perform lifting and lowering movements, thereby realizing automatic lifting and lowering adjustment of the U-shaped box 19 and the internal camera body 2. At this time, the lifting plate 14 is limited by the limit column 13 to reduce shaking. At the same time, the rubber roller 17 rolls in contact with the limit column 13, which can further reduce the shaking of the camera body 2 when it is lifted or lowered.

[0031] The adjusting plate 5, the first driving motor 7, the rotating shaft 8, the upper pulley 9, the lower pulley 10, the belt body 11, and the lifting plate 14 facilitate the automatic lifting and lowering adjustment of the camera body 2. At the same time, through the coordinated use with the limiting column 13, the U-shaped seat 16, and the rubber roller 17, the shaking of the camera body 2 during lifting and lowering can be reduced, which is conducive to improving the stability of the camera body 2 during lifting and lowering, thereby improving the stability of shooting, thereby improving the clarity of the shooting of the camera body 2.

[0032] like Figure 1-Figure 3 and Figure 6-Figure 8 As shown, a first hydraulic push rod 20 is fixed to the left side of the support plate 3 , the first hydraulic push rod 20 is electrically connected to the PLC controller, and one end of the telescopic rod of the first hydraulic push rod 20 is fixedly connected to the bottom surface of the adjustment plate 5 .

[0033] During use, when the vibration amplitude of the belt body 11 is too large, the adjustment plate 5 can be raised and lowered by starting the first hydraulic push rod 20, thereby driving the upper pulley 9 to be raised and lowered, thereby adjusting the tension of the belt body 11, effectively reducing the influence of the vibration of the belt body 11 on the shooting stability, and further reducing the shaking of the camera body 2 when it is raised and lowered.

[0034] like Figure 1-Figure 3 and Figure 6-Figure 8 As shown, a laser displacement sensor 21 is fixed on the right side of the support plate 3, and the laser displacement sensor 21 is electrically connected to the PLC controller. Slide grooves 22 are respectively provided on the front and rear sides of the inner wall of the movable groove 4, and sliders 23 are respectively fixed on the front and rear sides of the adjustment plate 5. The two sliders 23 are slidably arranged in the two slide grooves 22, and a mounting hole 24 is provided on the right side of the lower pulley 10. A bearing 25 is fixed inside the mounting hole 24, and a support shaft 26 is fixed to the inner wall of the inner ring of the bearing 25. The left end of the support shaft 26 is fixedly connected to the right side of the support plate 3.

[0035] In use, the laser displacement sensor 21 uses a laser beam to illuminate the surface of the belt body 11. By measuring the change of the reflected light of the laser beam on the surface of the belt body 11, the displacement and vibration of the belt body 11 can be accurately measured. When the vibration amplitude of the belt body 11 is too large, the information is transmitted to the PLC controller, and the first hydraulic push rod 20 is started to lift the adjustment plate 5, so that the tension of the belt body 11 can be automatically adjusted. The slide groove 22 and the slider 23 are used to limit the adjustment plate 5, prevent the adjustment plate 5 from deflecting, improve the stability of the adjustment plate 5 when it is lifted, improve the stability of the entire device, and form a stable guiding effect. The bearing 25 and the support shaft 26 are used to support the lower pulley 10. The use of the bearing 25 reduces the friction resistance of the lower pulley 10 when it rotates, making it rotate more smoothly. The bearing 25 can withstand large loads and speed changes, effectively reducing the wear between the lower pulley 10 and the support shaft 26, improving the durability of the lower pulley 10, and extending the service life of the equipment.

[0036] like Figure 1 , Figure 2 , Figure 5 and Figure 7 As shown, a connecting hole 27 is provided on the top surface of the lifting plate 14, and a second drive motor 28 is fixed inside the connecting hole 27. The output shaft of the second drive motor 28 is fixedly connected to the bottom surface of the U-shaped box 19. Movable holes 29 are respectively provided on the left and right sides of the outer wall of the U-shaped box 19. Second hydraulic push rods 30 are respectively fixed on the left and right sides of the outer wall of the U-shaped box 19. One ends of the telescopic rods of the two second hydraulic push rods 30 are respectively slidably inserted in the two movable holes 29, and one ends of the telescopic rods of the two second hydraulic push rods 30 are respectively fixed with rubber pads 31.

[0037] During use, when the shooting angle of the camera body 2 needs to be adjusted, the second drive motor 28 is started to rotate, thereby driving the U-shaped box 19 and the internal camera body 2 to rotate and adjust, realizing the multi-angle shooting function of the camera body 2 and improving the flexibility and diversity of shooting. After the staff places the camera body 2 inside the U-shaped box 19, the second hydraulic push rod 30 is started to make its telescopic rods approach each other and insert them into the movable hole 29. The U-shaped box 19 and the internal camera body 2 are fixed by the clamping action of the telescopic rod. When the camera body 2 needs to be disassembled, it is only necessary to reversely operate the second hydraulic push rod 30, which simplifies the disassembly and assembly process of the camera body 2 and improves work efficiency. At the same time, the clamping action of the second hydraulic push rod 30 realizes the stable fixation of the camera body 2, ensuring stability during shooting. When the second hydraulic push rod 30 clamps the U-shaped box 19, the rubber pad 31 first contacts the U-shaped box 19 and produces a certain compression deformation. This compression deformation not only enhances the stability of the clamping but also plays a certain buffering role, reducing the impact and wear of the second hydraulic push rod 30 on the U-shaped box 19 and the internal camera body 2, while increasing the friction between the clamping surface and the U-shaped box 19 to improve the stability of the clamping.

[0038] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
