Opposite-pulling screw cleaning machine

Abstract

For the pull-screw cleaning and milling machine, a hollow shaft is fixed on the console through rotating bearing seat, and a driven pulley is fixed on the hollow shaft. A motor is installed on the lower part of the console, and a driving pulley is installed on the shaft end of the motor. The driving pulley and The driven pulley is connected through a transmission belt. One end of the hollow shaft is fixed with a wrench tooth, and the other end of the hollow shaft is fixed with a nut sleeve. Rod slides are provided on both sides of the hollow shaft through guide sleeves. At both ends of the guide sleeve There is a hand wheel type sliding screw clamping device on the outer rod slide, and a reverse control button for controlling the motor is installed on the console. Compared with the existing technology, the present invention can easily clean off the hardened mortar stuck to the pull bolts, disassemble the nuts, straighten the screws, and reuse the screws after being soaked in oil, and the cleaning cost is relatively low. .

Description

technical field [0001] The invention relates to building construction equipment, in particular to a counter-pull screw cleaning and milling machine. The equipment can improve the turnover rate of the pull bolts commonly used in the building construction formwork reinforcement process, and effectively reduce the construction cost. Background technique [0002] In the construction of formwork engineering, it is often used to reinforce the formwork of frame columns, beams and shear walls with full-wire screws and butterfly cards and nuts. The bolts pass through the structural solid part and cover the PVC pipe. After the structure is poured and formed, it will The pull bolt can be pulled out for turnover. However, in the actual construction process, the thread is often blocked due to the sticky mortar and hardening of the screw. After one or two uses, it is difficult to install the nut again, causing the screw to fail and need to be purchased again. If manual cleaning requires...

AI Technical Summary

Problems solved by technology

However, in the actual construction process, the thread is often blocked due to the sticky mortar and hardening of the screw. After one or two uses, it is difficult to install the nut again, resulting in the failure of the screw, and it needs to be purchased again.

If manual cleaning requires oil immersion and then brushing with a wire brush or beating to make the ash fall off, the effect is not good, and the investment in man-hours is low and the efficiency is low, which is not economical
