DETAILED DESCRIPTION
[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0021] like Figures 1 - 3 As shown, the embodiment of the utility model provides a lifting stable electric hoist, comprising:
[0022] Guide rail 1, a connecting frame 2 is installed on the guide rail 1, a moving assembly 3 is installed on the connecting frame 2, the moving assembly 3 includes a running trolley and a brake, the moving assembly 3 is a prior art, and will not be repeated here, the moving assembly 3 is installed on the guide rail 1, a winding device 4 is installed on the connecting frame 2, the winding device 4 includes a motor, a reducer and a winding drum, the winding device 4 is a prior art, and will not be repeated here, a steel cable 5 is installed on the winding device 4, a connecting plate 6 is rotatably connected to the connecting frame 2, a guide disk 7 is rotatably connected to the connecting plate 6, and the steel cable 5 is installed on the guide disk 7;
[0023] A lifting ring 8 is installed on the steel cable 5, a lifting hook is installed on the lifting ring 8, and a plurality of buffer components and a protective component are installed on the connecting frame 2; the protective component includes a connecting roller that rotates and penetrates the connecting plate 6, one end of the connecting roller is fixedly connected to the guide plate 7, a sprocket 9 is fixedly connected to the connecting roller, a fixing frame 10 is fixedly connected to the connecting plate 6, and a hydraulic cylinder 11 is fixedly connected to the fixing frame 10. The hydraulic cylinder 11 is a prior art and will not be described here. The telescopic end of the hydraulic cylinder 11 slides through the fixing frame 10 and is fixedly connected to the support plate 12;
[0024] A telescopic rod 13 and a spring 14 are fixedly connected to the support plate 12, the telescopic rod 13 is sleeved in the spring 14, a toggle block 15 is fixedly connected to the telescopic rod 13 and the spring 14, the toggle block 15 rotates on the connecting plate 6, and the buffer assembly includes a fixed plate 16 fixedly connected to the connecting frame 2, a spring frame 17 is fixedly connected to the fixed plate 16, a buffer pad 18 is fixedly connected to the spring frame 17, and a buffer pad layer is laid on the buffer pad 18 to improve the buffering effect.
[0025] The detailed working process of the utility model is as follows:
[0026] The user installs the device at the designated workplace, and then the user installs the object on the hook on the lifting ring 8. When the lifting work is performed, the winding device 4 starts to work first to wind up the steel cable 5 to realize the lifting of the object. During the lifting process, the steel cable 5 is continuously wound, so that the guide plate 7 is continuously rotated, and at the same time, the connecting plate 6 rotates on the connecting frame 2, and the toggle block 15 located on the connecting plate 6 will continuously toggle the sprocket 9. When the lifting work is completed, the winding device 4 stops working and the sprocket 9 stops rotating. After the sprocket 9 stops rotating, the toggle block 15 located on the connecting frame 2 will support the sprocket 9, which can limit the sprocket 9, and can cooperate with the winding device 4 to move the steel cable 5. The guide plate 7 is fixed to prevent the guide plate 7 from rotating, thereby improving the stability of the device. When it is necessary to lower the object, the hydraulic cylinder 11 starts working first, driving the support plate 12 to move down, and at the same time, the telescopic rod 13 and the spring 14 cooperate to pull the toggle block 15 down. At this time, the winding device 4 starts working to realize the lowering work. When it is necessary to move the object in the horizontal direction, the device moves on the guide rail 1 through the moving component 3. When the device moves to the two ends of the guide rail 1, the spring frame 17 and the toggle block 15 on the connecting frame 2 can buffer the connecting frame 2, so that the device slowly contacts the end point of the guide rail 1, avoiding the connecting frame 2 from being hit and causing the device to swing, thereby improving the stability of the device.
