Description

Technical Field

[0002] A lifting device for mechanical and electrical equipment maintenance is a device specially designed to lift and lower heavy equipment or components. This device is usually used for equipment parts that need to be regularly inspected, maintained or replaced, such as large machinery, factory equipment or elevator systems in buildings. During the maintenance process, the lifting device can safely and accurately lift the equipment to a height suitable for workers to operate or maintain, while also ensuring a safe and efficient working environment.

[0003] Traditional mechanical and electrical equipment maintenance lifting devices usually use a screw and nut combination to achieve the lifting function. This structure is precisely designed and can provide highly accurate lifting control to ensure that the equipment remains stable and safe during operation. Due to the close fit between the screw and the nut, this device can withstand large vertical loads and maintain smooth operation during the lifting process. It is widely used in various industrial environments that require long-term continuous operation.

[0004] However, due to the rotational motion of the screw and the moving friction of the nut, energy loss will increase, thereby reducing the overall energy efficiency ratio, generating more noise and vibration during operation, affecting the quietness of the working environment. The complex screw structure also increases the cost of maintenance and servicing, and regular lubrication and inspection are required to ensure normal operation, which is especially important for industrial equipment that runs for a long time. Therefore, a lifting device for electromechanical equipment maintenance is proposed to solve the above problems. Utility Model Content

[0034] Specifically, the starting motor 8 drives the driving wheel 4 to rotate, and the driving wheel 4 is transmitted to the driven wheel 5 through the belt 6. Since the driven wheel 5 is fixed with a rotating shaft 9, the rotating shaft 9 rotates accordingly, and the movement of the rotating shaft 9 drives the sprocket 10 to rotate. Since the sprocket 10 is meshed with the outer wall of the chain 11, the rotation of the sprocket 10 drives the chain 11 to move, ensuring stable and low-friction transmission, thereby causing the support frame 13 to rise rapidly and the counterweight block 12 to descend, so that the repair personnel can reach the working position safely and quickly, minimize energy loss and operating noise, and improve the lifting efficiency of the lifting device.

[0035] Reference Figure 3 , the protection assembly includes an outer shell 14, the bottom of the outer shell 14 is fixedly connected to the top of the support frame 13;

[0036] Specifically, the outer shell 14 is made of aluminum alloy as the main material, has good durability, and maintains stability and long-term reliability under various environmental conditions, ensuring the safety of repair personnel when lifting and lowering the equipment.

[0037] Reference Figure 3 , Figure 4 and Figure 5 The inner wall of the outer shell 14 is fixedly connected with a left-right symmetrical fixed block 17, a fixed ring 22 is fixedly connected inside the fixed block 17, a sliding column 23 is slidably connected to the inner wall of the fixed ring 22, a triangular block 21 is fixedly connected to one side of the outer wall of the sliding column 23, a spring 18 is arranged between the triangular block 21 and the fixed ring 22, one end of the spring 18 is fixedly connected to one side of the outer wall of the triangular block 21, the other end of the spring 18 is fixedly connected to one side of the outer wall of the fixed ring 22, a pull bolt 19 is fixedly connected to one side of the outer wall of the sliding column 23, a sliding rod 20 is fixedly connected to one side of the inner wall of the outer shell 14, a ball handle 16 is slidably connected to the outer wall of the sliding rod 20, a door panel 15 is rotatably connected to one side of the outer wall of the outer shell 14, and the inner wall of the door panel 15 is fixedly connected to the outer wall of the ball handle 16;

[0038] Specifically, the pull bolt 19 is pulled outward, and the pull bolt 19 drives the sliding column 23 to move outward on the inner wall of the fixing ring 22, thereby driving the triangular block 21 to move outward, so that the spring 18 is in a compressed state. At this time, by pulling the ball handle 16 outward, the ball handle 16 slides outward on the outer wall of the slide rod 20, thereby driving the rotation of the door panel 15, thereby realizing the opening of the device. The maintenance personnel enter the device, and the triangular block 21 can lock the bottom of the ball handle 16, thereby preventing the door panel 15 from accidentally opening due to vibration or collision during movement. The device is simple and easy to operate, and the protection performance of the device is improved.

[0039] Working principle: First, when it is necessary to repair the electromechanical equipment, pull the pull bolt 19 outward to drive the sliding column 23 to move outward on the inner wall of the fixing ring 22, thereby driving the triangular block 21 to move outward, so that the spring 18 is in a compressed state, and at this time, pull the ball handle 16 outward to drive the ball handle 16 to slide on the outer wall of the slide rod 20, thereby driving the door panel 15 to rotate, thereby opening it. After the repairman enters the device, he closes the door panel 15 according to the same principle, starts the motor 8 to drive the driving wheel 4 to rotate, and the driving wheel 4 drives the driven wheel 5 to rotate through the belt 6. Since the outer wall of the driven wheel 5 is fixed with a rotating shaft 9, the rotating shaft 9 is driven to rotate, and further drives the sprocket 10 to rotate. Since the outer wall of the sprocket 10 is meshed with the outer wall of the chain 11, the rotation of the sprocket 10 drives the chain 11 to rotate, thereby driving the support frame 13 to rise, and at the same time the counterweight block 12 descends, completing the lifting of the repairman.
