Screw elevator is a common lifting equipment, which is mainly used in various occasions that require vertical lifting, such as elevators, tower cranes, escalators, etc. This article will introduce the instructions for the use of the screw lift in detail to help users better use and maintain the lift.
First, the structure and working principle of the screw lift.
The screw elevator is mainly composed of screw rod, nut, slider, transmission box and motor, etc. Among them, the screw rod is a kind of rotating shaft, which is driven by a motor to rotate, and the nut is driven to move up and down along the axis of the screw rod, so as to convert the rotary motion into a vertical lifting motion. The slide is mounted inside the nut and is used to carry the load. The function of the gearbox is to transmit the rotational motion output by the motor to the screw rod.
Second, the installation and use of the screw lift.
1.Preparation before installation.
Before installing the screw lift, it is necessary to check whether the various parts of the lift are intact, and if there is damage, they should be replaced in time. At the same time, it is necessary to confirm whether the environment of the installation site meets the requirements, such as whether the ground is flat and whether there is enough space.
2.Installation Steps.
1) Place the lift on the object that needs to be lifted, adjust the height of the lift so that the slider is in the middle position of the screw rod.
2) Fix the motor and gearbox, insert the screw into the output shaft of the motor, and tighten the screws.
3) Turn on the power, start the motor, and check whether the screw elevator is working normally. If there is abnormal sound or vibration, it should be stopped for inspection in time.
3.Precautions for use.
1) During use, overload should be avoided to avoid damaging the equipment.
2) Regularly check the wear and tear of screw rods, nuts and other components, and replace them in time if there is any problem.
3) Keep the equipment clean and avoid debris from entering between the screw and the nut.
3. Maintenance and maintenance of screw lift.
1.Regular check-ups.
The screw hoist should be inspected regularly, including screw rods, nuts, sliders, motors and other components. Inspect the parts for wear, looseness, or damage.
2.Lubrication maintenance.
Screw lifts need to be lubricated and maintained regularly. During use, grease should be added between the screw and the nut regularly to ensure the normal operation of the equipment. At the same time, it is necessary to regularly clean oil and debris to keep the equipment clean.
3.Repair and replacement.
If the parts are found to be damaged or severely worn, they should be repaired or replaced in time. For example, the wear of the screw and nut should be replaced in time to ensure the stability and safety of the equipment.
Fourth, the safety operation procedures of the screw lift.
1.Operators must be professionally trained and familiar with equipment operating procedures and safety precautions.
2.The operating procedures should be strictly followed during operation, and the equipment should not be overloaded.
3.In the process of use, you should pay attention to the operation of the equipment at any time, and if you find abnormal sound or vibration, loose or falling off parts, etc., you should stop the machine in time for inspection and treatment.
4.During equipment repair and maintenance, the power supply must be cut off to ensure safety.
5.Keep the equipment clean and perform regular care and maintenance.
In a word, screw elevator is an important vertical lifting equipment, which is widely used in various occasions. In the process of use, the operating procedures and safety precautions should be strictly observed, and regular maintenance and maintenance should be carried out to ensure the stability and safety of the equipment. At the same time, the operator must be professionally trained, familiar with the equipment structure and working principle, and be able to correctly deal with various emergencies.
