[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1 Please see Figure 1-7 A hoisting device for a vertical lifting concrete mixing plant includes a mounting base 1 and an opening on the top of the mounting base 1 near the left side. A hoist drum 2 is installed on the top of the mounting base 1 near the upper left. A rotating rod is fixedly installed through the middle of the upper part of the hoist drum 2. Bearing seats 3 are provided at both ends of the hoist drum 2. The bottom of the bearing seats 3 is fixedly installed on the mounting base 1. The left end of the rotating rod is movably installed on the left bearing seat 3, and the right end of the rotating rod movably extends through to the outside of the right bearing seat 3. A reducer body 4 is fixedly installed on the top of the mounting base 1 near the right side. The output end of the reducer body 4 is fixedly connected to the right end of the rotating rod. A drive motor 5 is provided on the right side of the rear side of the reducer body 4. The output end of the drive motor 5 is fixedly connected to the input end of the reducer body 4. A monitoring component 6 is installed on the rear side of the reducer body 4 near the lower left. An anti-fall component 7 is installed on the outside of the output shaft of the reducer body 4.

[0021] The monitoring component 6 includes a protective groove 61 located on the lower left side of the rear side of the reducer body 4. The bottom of the protective groove 61 is fixedly mounted on the mounting base 1, and a connecting base 62 is fixedly mounted on the right side of the inner cavity of the protective groove 61. An electromagnet 63 is fixedly mounted on the left side of the connecting base 62, and a magnet block 64 is provided at the left end of the electromagnet 63. A button block 65 is provided on the left side of the protective groove 61, and a switch button 66 is provided on the left side of the button block 65. A thermistor 67 is fixedly mounted in the middle of the rear side of the drive motor 5. The thermistor 67 can monitor the temperature of the drive motor 5 during operation. When the temperature is abnormal, it can drive the button block 65 to move, thereby contacting the switch button 66 to cut off the power to the drive motor 5 and prevent it from continuing to run and causing irreversible damage.

[0022] The left side of the magnet 64 near the top is elastically connected to the inner wall of the protective groove 61 by a telescopic spring 641, which facilitates the movement and restoration of the magnet 64.

[0023] A connecting rod 651 is fixedly installed at the middle of the right side of the button 65, and the right end of the connecting rod 651 slides through and extends into the inner cavity of the protective groove 61, and is fixedly installed on the magnet block 64, which can drive the button 65 to move left and right synchronously with the magnet block 64.

[0024] A support plate 661 is fixedly installed on the left side of the switch button 66, and the bottom of the support plate 661 is fixedly installed on the mounting base 1, which serves to support and fix the switch button 66.

[0025] A support base 51 is fixedly installed at the bottom of the drive motor 5, and the bottom of the support base 51 is fixedly installed on the mounting base 1, which serves to support and fix the drive motor 5 and prevent it from being suspended in the air.

[0026] In this embodiment: During use, the operation of the drive motor 5 drives the reducer body 4, which in turn drives the winch drum 2 to rotate, thus realizing the lifting and lowering of the hopper. In addition, the thermistor 67 can monitor the temperature of the drive motor 5 during operation. When the drive motor 5 malfunctions, the temperature will be abnormal. The thermistor 67 can sense the temperature rise. When the temperature rises, the resistance of the thermistor 67 will decrease, thereby increasing the current. At this time, the magnetic repulsion between the electromagnet 63 and the magnet block 64 will increase, thus pushing the magnet block 64 to the left. When the magnet block 64 moves, it will drive the button 65 to the left through the connecting rod 651. When the button 65 moves to the left, it will contact the switch button 66, thereby stopping the drive motor 5 and facilitating timely inspection and maintenance of the drive motor 5 by the staff.

[0027] Example 2 This embodiment is an improvement upon embodiment 1. For details, please refer to [link / reference]. Figure 1 , Figure 4-5 and Figure 7 The anti-fall component 7 includes two arc-shaped clamping plates 71 located on the outer side of the output end of the reducer body 4. The arc-shaped clamping plates 71 are arranged front and rear. A threaded sleeve 72 is provided at the bottom of each arc-shaped clamping plate 71. A threaded rod 73 is threaded through the middle of the upper part of each threaded sleeve 72. The external threads of the threaded rods 73 on the front and rear sides are arranged oppositely. A transmission rod is fixedly installed on the opposite end of the threaded rods 73. A driven bevel gear 74 is fixedly sleeved on the outer side of the transmission rod. A driving bevel gear 75 meshes with the left side of the driven bevel gear 74. A servo motor 76 is provided on the left side of the driving bevel gear 75. The output end of the servo motor 76 is fixedly connected to the middle of the left side of the driving bevel gear 75. It can drive the arc-shaped clamping plates 71 on the front and rear sides to move synchronously, thereby clamping and fixing the output shaft of the reducer body 4 and preventing the winch drum 2 from continuing to rotate when the transmission motor 5 fails, which poses a certain danger.

[0028] A fixing rod 711 is fixedly installed at the middle of the bottom of the arc-shaped clamping plate 71, and the lower end of the fixing rod 711 is fixedly installed on the adjacent threaded sleeve 72, which can drive the arc-shaped clamping plate 71 to move synchronously with the threaded sleeve 72.

[0029] Each threaded sleeve 72 has a sliding plate 721 fixedly installed at its bottom, and a sliding rod 722 is slidably installed through the sliding plate 721. Side plates 723 are fixedly installed at both ends of the sliding rod 722. The bottom of each side plate 723 is fixedly installed on the mounting base 1, and the opposite end of the threaded rod 73 is movably installed on the adjacent side plate 723. This serves to guide and limit the movement of the threaded sleeve 72, allowing it to move stably back and forth, and also to support the rotation of the threaded rod 73.

[0030] A mounting bracket 761 is fixedly installed at the middle of the top of the servo motor 76, and the lower end of the mounting bracket 761 is fixedly installed on the mounting base 1, which serves to support and fix the servo motor 76.

[0031] In this embodiment: when the drive motor 5 is de-energized, the operator can run the servo motor 76. When the servo motor 76 runs, it drives the active bevel gear 75 to rotate. When the active bevel gear 75 rotates, it drives the transmission rod to rotate through the driven bevel gear 74. When the transmission rod rotates, it drives the threaded rods 73 on the front and rear sides to rotate synchronously. When the threaded rods 73 rotate, they drive the adjacent threaded sleeves 72 to move relative to each other. When the threaded sleeves 72 move relative to each other, they drive the arc-shaped clamping plates 71 on the front and rear sides to move relative to each other through the adjacent fixing rods 711. This clamps and fixes the output end of the reducer body 4, preventing the winch drum 2 from continuing to run and improving safety during use.

[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
