Product Description

Screw Jack System - Tank Lifting Construction Equipment

Petroleum storage tank is an important storage facility in the petroleum industry, and its construction quality directly affects the safe operation and service life of the storage tank. In the installation and maintenance of petroleum storage tanks, jacking operations are particularly critical, requiring precise control and a high degree of safety.

With the continuous advancement of industrial technology, the demand for precise control of heavy equipment is also increasing. As a widely used and superior jacking solution, the design of the lead screw jacking machine not only requires strong bearing capacity and high stability, but also takes into account the convenience and safety of operation.

The purpose of this scheme is to illustrate the application and advantages of lead screw jacking in the construction of oil storage tanks.

PLC Electrically Controlled Lead Screw Jacking Mechanical System for Grain Storage Silos

Specification

Design Overview

The design goal of the lead screw jack is to achieve efficient, stable and safe jacking operations. The design takes into account the convenience of user operation, the reliability of the equipment and the ease of maintenance.

Applications

As an advanced mechanical tool, the lead screw jacking machine has been widely used in the construction of petroleum storage tanks because of its advantages of simple structure, convenient operation, strong bearing capacity and stable jacking.

Major Components

1. Key Configurations:

Main structure: high-strength steel is used to ensure the bearing capacity and fatigue resistance of the jacking machine.
Bracket structure: mainly made of Q235B material to ensure the overall stability of performance.
Modular design: Modular components for quick assembly, disassembly and transportation.
Bottom support: Set up the bottom support with adjustable height to ensure the stability of the jacking machine on different grounds.

Transmission System

2. Transmission Features:

Lead screw system: select high-precision, high-wear-resistant ball screws to ensure smooth and accurate jacking process.
Drive mechanism: Servo motor or stepper motor is used to control the lead screw to achieve precise fine-tuning ability.
Reducer: Cooperate with a suitable reducer to reduce the motor load and provide sufficient torque.

Control Systems

3. System Integration:

Automatic control: Integrate advanced PLC control system to achieve automatic lifting and position control.
Human-machine interface: The design is friendly to the human-machine interface, which can detect the running status of each motor.
Features: The servo motor is used with the planetary reducer to ensure the synchronous operation of the screw jacking and the error is within 2mm.

Advantages of Screw Design

High precision: The use of ball screws ensures high precision and stability in the jacking process.
Easy maintenance: Considering the convenience of maintenance, the jacking machine can maintain good performance for a long time.
Precise control: The screw jacking machine can achieve precise control at the micron level through the fine screw transmission system to ensure the stability and accuracy of the storage tank in the jacking process.
Easy to operate: Modular design and user-friendly interface make operation more simple and intuitive.
Strong bearing capacity: The lead screw jacking machine can be designed as a multi-stage combined type to meet the needs of tank jacking of different weights and heights.
Safe and reliable: with self-locking function, it can keep the jacking position stable even in the case of power failure and other emergencies, avoid accidents, and ensure the safety of jacking operations.
