AI Technical Summary

Technical Problem

Existing pipe lifting and conveying devices cannot simultaneously achieve both stability and mobility; they are unstable when rollers are installed at the bottom and inconvenient to move when supports are installed at the bottom.

Method used

The base design incorporates a roller retraction device and a lifting assembly. The rollers extend and retract via a motor-driven screw and slider. The pipe is secured by a limit block and nut, achieving a balance between stability and mobility.

Benefits of technology

This achieves a balance between stability and mobility in the pipe lifting and conveying device, ensuring stable support and convenient movement when needed.

Abstract

This utility model relates to the field of construction engineering technology and discloses a pipe lifting and conveying device for construction engineering. It includes a base, a slide rail fixedly connected to the top of the base, a lifting assembly installed above the base, and a roller retraction device installed at the bottom of the base. The roller retraction device includes a base plate, a second motor fixedly connected to the outer side of the base plate, a screw fixedly connected to the output end of the second motor, the screw rotatably connected to the top of the base plate, a slider threadedly connected to the outer side of the screw, and fork-shaped frames rotatably connected to both sides of the slider. Multiple rollers are installed at the bottom of the base plate. In this utility model, the first motor drives the rotating drum to rotate, causing the wire rope to wind or unwind, thereby raising or lowering the lifting frame to convey the pipe. The second motor sequentially drives the screw, slider, and fork-shaped frames, causing the rollers to extend or retract for easy movement of the lifting and conveying device.
