Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of concrete pipe manufacturing, and particularly relates to a reinforced concrete pipe finishing device. BACKGROUND

[0002] Reinforced concrete pipe is a composite pipe material composed of steel bars and concrete. Concrete provides compressive strength, and steel bars are used to enhance the tensile performance of the pipe material. However, the surface of the concrete may have defects due to various factors during the pouring and molding process. For example, during the concrete vibrating process, there may be a situation of insufficient vibration, resulting in honeycomb and pitted surface on the surface. In addition, after the concrete pipe is demolded, there may be some small pores, cracks and other defects on the surface. If these defects are not treated, groundwater, sewage and other liquids may seep into the pipe body through these defects during the use of the pipe, causing corrosion of the steel bars and reducing the service life of the pipe. Moreover, the uneven surface will increase the water flow resistance and affect the drainage efficiency.

[0034] An installation rod 8 is arranged on the fixed ring 3, and an outer scraper 81 is arranged on the installation rod 8 close to the fixed seat 1.

[0035] Specifically, in the working process, the concrete pipe is placed on the movable ring 2 and is sleeved with the inner mechanism 5; the rotating ring 59 is rotated to move towards the threaded shaft 7, thereby driving the passive ring 510 to move, the first connecting rod 53 is rotated to drive the connecting block 56 to move outward, the second connecting rod 54 and the third connecting rod 55 are synchronously rotated, the inner scraper 57 is attached to the inner wall of the concrete pipe, and the outer scraper 81 is attached to the outer wall of the concrete pipe; then the movable ring 2 is rotated to drive the concrete pipe to rotate, the inner scraper 57 and the outer scraper 81 simultaneously perform the troweling on the inner wall and the outer wall of the concrete pipe respectively; after the working process is completed, the movable ring 2 is stopped, the rotating ring 59 is rotated to move away from the threaded shaft 7, the connecting block 56 is moved inward, and the concrete pipe is taken off.

[0036] As a specific embodiment of the utility model, the bottom of the movable ring 2 is provided with a gear ring 21.

[0037] A first gear 22 is rotationally arranged on the movable ring 2, and the first gear 22 is engaged with the gear ring 21.
