Lifting type building steel pipe inner wall derusting and polishing device

Abstract

The invention discloses a lifting type building steel pipe inner wall derusting and polishing device, and relates to the technical field of building machineries. The lifting type building steel pipe inner wall derusting and polishing device comprises a fixing frame, wherein a polishing mechanism used for derusting the inner wall of a steel pipe is arranged on a second spur rack, and a lifting mechanism used for driving a supporting plate to vertically ascend and descend is in driving connection with a motor; and a rotating mechanism for driving a supporting seat to rotate is arranged at the bottom of the supporting plate. According to the lifting type building steel pipe inner wall derusting and polishing device, the steel pipe is limited through the arranged clamping mechanism, the arranged lifting mechanism can drive the clamping mechanism to drive the steel pipe to vertically reciprocate relative to the grinding mechanism, and under the driving effect of the rotating mechanism, thesteel pipe vertically reciprocates and simultaneously rotates clockwise and anticlockwise alternately; and the full rotary polishing effect of a polishing plate in the polishing mechanism on the innerwall of the steel pipe is achieved; a sleeve wheel in the polishing mechanism rotates, the distance adjusting effect of the polishing plate relative to a stand column can be achieved, flexible adjustment is achieved according to the steel pipes with different inner diameters, and efficient and comprehensive rust removal of the steel pipes is guaranteed.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a lift-type derusting and grinding device for the inner wall of a construction steel pipe. Background technique [0002] Building construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. It includes basic engineering construction, main structure construction, roofing engineering construction, decoration engineering construction, etc. The place where the construction works is called "construction site" or "construction site", also called construction site. Steel pipes in building construction need to be derusted on their inner walls before use. [0003] The patent application publication number is CN106826504A discloses a steel pipe inne...

Problems solved by technology

[0003] The patent application publication number is CN106826504A discloses a steel pipe inner wall grinding and derusting device mainly composed of a grinding device, a guide device, and a rotating shaft; the grinding device is mainly composed of a plurality of grinding blocks, a plurality of springs, and a plurality of connecting rods A. It is mainly composed of four casings, four connecting rods B, and shaft sleeves. Its main working principle and process are: first insert the grinding device and guiding device into the steel pipe, and rotate the four casings of the guiding device to make the four casings The arc surface of the outer end of the steel pipe bears against the inner wall of the steel pipe, and the axis of the rotating shaft coincides with the central axis of the steel pipe, and the driving device of the rotating shaft is started, and the driving device drives the rotating shaft to rotate, and the rotating shaft drives the grinding device to rotate at the same time. The inner wall of the steel pipe rotates to complete a section of grinding and derusting work, and gradually pushes the rotating shaft to complete all the grinding and derusting work on the inner wall of the steel pipe; although this device can realize the derusting of the inner wall of the steel pipe, the grinding block cannot achieve relative to the steel pipe during the derusting process. Axial movement, the scope of steel pipe grinding is relatively limited. Therefore, a lifting type construction steel pipe inner wall derusting and grinding device is now provided to solve the above technical problems
