AI Technical Summary

Technical Problem

In the current bridge pile foundation construction, the sediment in the pile hole contains a lot of water and is sticky, which can easily block the discharge port of the screw elevator, preventing the sediment from being discharged normally and affecting the normal operation of the device.

Method used

The transmission components include a drive shaft, a driving bevel gear, and a driven bevel gear. Power is transmitted to the spiral blades through the transmission components to achieve synchronous rotation of the spiral blades and prevent sludge from clogging the discharge port.

Benefits of technology

This effectively prevents sediment from clogging the discharge port, ensuring that sediment can be discharged quickly, guaranteeing the normal operation of the equipment, and improving construction efficiency and quality.

Abstract

This utility model relates to the field of spiral elevator technology and discloses a spiral elevator for cleaning sediment from bridge pile foundations. It solves the problem that existing pile hole sediment, due to its high water content and viscosity, easily clogs the discharge port of the spiral elevator, preventing normal discharge and affecting the normal operation of the device. The device includes an installation box, with a fixed cylinder fixedly installed on one side and a conveying cylinder fixedly installed at the bottom. A discharge cylinder is fixedly installed at the upper end of the conveying cylinder, and a support frame is fixedly installed on the other side of the installation box. A drive motor is fixedly installed inside the fixed cylinder. A first conveying spiral is installed inside the conveying cylinder, and a second conveying spiral is installed inside the discharge cylinder. A transmission component is provided at the output end of the drive motor, and the transmission component is connected to the first and second conveying spirals. The discharge port of this spiral elevator will not be blocked by sediment, allowing for rapid discharge and ensuring the normal operation of the device.
