In scenarios with extensive spans and heavy loads, the use of screw conveyors typically involves multiple interconnected units. This approach ensures that each elevator carries a moderate load, allowing for synchronized movement across long spans without excessive lateral forces. Additionally, the entire system benefits from enhanced stability and safety. As a result, multi-unit interconnected solutions are more favored in design, with a broad application range and simplified installation and operation.
Multiple联动 schemes are crucial in the design phase, requiring clients to provide relevant data and considering factors such as installation space, working conditions, limit switches, and other aspects. However, the installation on-site after design completion and production shipment is also a vital step. As there are many aspects to pay attention to, such as the center height of individual units, coaxial alignment, guide devices, and the orientation of the directional box, etc. Today, we want to discuss how to avoid excessive deviation during the installation of multiple spiral hoists.
We'll start with the preparation steps. After the customer receives the screw jack, it's essential to ensure that the output and input shafts of the gear box, gear box, and motor units are at the same horizontal level. If there are differences in the center height, you can add appropriate shims to equalize the center height. Additionally, when using couplings or connecting rods for connection, it's crucial to align the axes accurately to prevent any tilting or binding issues.
If support platforms are required, attention must also be paid to their installation. We need to ensure that the installation surface of the screw or nut is at the same level, and the installation surface of the lift must be kept level as well. Additionally, each installation hole at the screw head (or nut installation hole) should be adjusted to align with the installation holes of the support platform before installing the platform. It is important to note that during the installation of the platform, lateral forces must be strictly prohibited from being applied to the screw.
