[0002] Cement pipes have important applications in the construction of urban water pipe networks. When manufacturing cement pipes, a suspension pipe machine is generally used. After the cement inside the mold hardens, the mold is disassembled. At this time, the outer surface of the cement pipe is relatively rough, and a large amount of coarse sand is exposed on the outer surface of the cement pipe. Therefore, it needs to be polished.

[0003] In the related art, reference can be made to the Chinese patent with the publication number CN212288127U, which specifically discloses a surface water circulation polishing device for cement pipes. When this surface water circulation polishing device for cement pipes is used, the distance is adjusted by a fixed seat and a movable seat, and a clamping frame is used to clamp the cement pipe. On one side of the cement pipe, a second hydraulic cylinder is used to drive a polishing plate for polishing. A cement infusion pipe is used on the polishing plate to supply cement for polishing to the polishing plate, and the polished sewage flows into the cement pump through a waste water tank, achieving the effect of reusing sewage, and realizing automatic polishing, which is convenient to use, simple to operate, high in efficiency, and widely used.

[0004] The applicant found that there are deficiencies in the use of the above-mentioned surface water circulation polishing device for cement pipes: Although the comparative document can polish the cement pipe, the length and position of the polishing plate are fixed, and it can only polish cement pipes of a specified length, resulting in reduced practicability.

[0005] In view of this, this technical solution proposes a surface treatment device for cement pipes, which is convenient to better solve the above-mentioned problems. Content of the Utility Model

[0011] In a preferred embodiment, anti-slip support plates are installed on both sides of the bottom of the base through telescopic rods, and anti-slip pads are provided at the bottoms of the anti-slip support plates. A threaded rod is fixed at the center of the top of the anti-slip support plate, and an internally threaded sleeve is threadedly connected to the threaded rod. The internally threaded sleeve is rotatably installed on the bottom of the base.

[0012] In a preferred embodiment, the moving plate fits against the top of the base, and limiting ears are integrally formed on both sides of the moving plate, and the limiting ears fit against the sides of the base.

[0013] In a preferred embodiment, the extended length of the electric telescopic rod is less than the length of the movable plate.

[0014] In a preferred embodiment, the connecting platform, the smoothing plate and the cement groove are inclined.

[0015] In a preferred embodiment, a protective ring for limiting and guiding the cement is fixed above the connecting platform.

[0016] In a preferred embodiment, the connecting platform, the smoothing plate, the cement groove and the protective ring are of an integrally formed structure.

[0017] In summary, due to the adoption of the above technical solutions, the beneficial effects of the present utility model are: it is convenient to better smooth cement pipes of various lengths, and the practicability is stronger.

[0025] Below will be combined with Figures 1 - 3 A device for surface treatment of cement pipes in an embodiment of the present utility model will be described in detail.

[0026] Referring to Figures 1 - 3 As shown, a device for surface treatment of cement pipes includes a base 1. Universal wheels 2 are provided around the bottom of the base 1. Anti-slip support plates 4 with adjustable positions are provided on both sides of the bottom of the base 1 to provide anti-slip support for the base 1. The anti-slip support plates 4 are installed on both sides of the bottom of the base 1 through telescopic rods 3, and anti-slip pads are provided at the bottoms of the anti-slip support plates 4. A threaded rod 5 is fixed at the center of the top of the anti-slip support plate 4, and an internal thread sleeve 6 is threadedly connected to the threaded rod 5, and the internal thread sleeve 6 is rotatably installed on the bottom of the base 1.

[0027] Referring to Figures 1 - 2As shown, a chute 7 is provided at the internal center position of the base 1, and a lead screw 8 is rotatably installed inside the chute 7. A motor 9 is fixed in front of the base 1, and the output end of the motor 9 is fixedly connected to the lead screw 8. A slider 10 is inserted into the chute 7, and the slider 10 is threadedly connected to the lead screw 8. A moving plate 11 is fixed to the top of the slider 10. The moving plate 11 is in contact with the top of the base 1, and limiting ears 12 are integrally formed on both sides of the moving plate 11, and the limiting ears 12 are in contact with the side of the base 1.

[0028] Reference Figures 1 - 2 As shown, a fixed sleeve 14 is connected to the top of the moving plate 11 through a hydraulic cylinder 13, and a movable plate 15 is slidably installed inside the fixed sleeve 14. A connecting platform 16 is fixed to the left side of the movable plate 15. A fixed ear 17 is fixed to the left side of the top of the fixed sleeve 14, and an electric telescopic rod 18 passes through the fixed ear 17. The extending end of the electric telescopic rod 18 is connected to the connecting platform 16, and the extending length of the electric telescopic rod 18 is less than the length of the movable plate 15.

[0029] Reference Figures 1 - 2 As shown, a finishing plate 19 for finishing the cement pipe is arranged on the left side of the connecting platform 16, and a cement groove 20 is arranged above the space between the connecting platform 16 and the finishing plate 19. The connecting platform 16, the finishing plate 19 and the cement groove 20 are inclined. A protective ring 21 for limiting and guiding the cement is fixed above the connecting platform 16.
