The bottom plate serves as the base of the entire device, and side plates are fixedly connected on both sides thereof, which increases the stability and load-bearing capacity of the equipment. The upper end of the side plate is connected to the lifting motor, which is the power source of the entire device. The output end of the lifting motor is connected to a screw. This design can realize the conversion of the rotational motion of the motor into the vertical motion of the lifting plate. A lifting plate is arranged inside the bottom plate, and a wear-resistant plate is connected to the upper end of the lifting plate. The friction is increased by the wear-resistant plate to realize the lifting. The plate supports and places the equipment as a whole. On both sides of the lifting plate, binding belts are connected by buckles. The binding belts can fix the two ends of the equipment during the lifting process. On both sides of the lifting plate, two lifting motors are used to rotate synchronously. The screw drives the lifting plate to move up under the drive of the motor. Limit rods are connected on both sides of the lifting plate. The lifting plate is limited by the limit rods, making the lifting plate more stable during the lifting process, further ensuring the stable lifting of the equipment. The patented equipment lifting device has a simple structure, is easy to operate, safe and reliable, and is highly energy-efficient. Its application can greatly improve the efficiency and safety of equipment lifting in construction projects, and reduce the labor intensity and operation risks of workers.
