AI Technical Summary

Technical Problem

The existing bridge wet joint formwork lifting device is prone to drive wheel wobbling during construction, which affects the installation accuracy.

Method used

The device employs a design that combines spur gears and a transmission belt. The drive wheel is fixed by the meshing of the spur gear and the rack. The contact area between the connecting column and the ground is increased by the engagement of the drive thread and the limiting sleeve. Meanwhile, the design of the extension column and the pin improves the stability and ease of use of the device.

Benefits of technology

It improves the stability of the drive wheel, reduces swaying, enhances installation accuracy and overall device stability, ensures stability during long-term movement and the stability of the transmission belt, and extends the service life of the drive wheel.

Abstract

This utility model belongs to the field of bridge construction technology, specifically a bridge wet joint template lifting device, including a fixed frame; a lifting component is provided on the top of the fixed frame; a drive wheel is rotatably connected to both ends of one side of the bottom of the fixed frame; a connecting rotating column is fixedly connected to one side wall of the drive wheel; a spur gear is fixedly connected to the outer side wall of the connecting rotating column; and spring columns are provided at both ends of one side of the bottom of the fixed frame. During operation, the spur gear can cooperate with the transmission belt to drive the spur gear to rotate. The rotating spur gear can cause the rack and the closing retaining ring to move downward, so that the closing retaining ring and the spur gear mesh with each other, thereby achieving the fixation of the connecting rotating column and the drive wheel. The overall device makes the drive wheel more stable during construction and reduces the occurrence of drive wheel wobbling, which could affect the installation accuracy.
