[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0028] Referring to Figures 1-5 , an embodiment provided by the present utility model: a pier body concrete spraying and curing device, including a pier top spraying component 1 fixed on the top of the concrete pier body 9 and a pier body spraying component 2 surrounding the surface of the concrete pier body 9. A water tank 3 is provided to match the pier top spraying component 1 and the pier body spraying component 2, and the water tank 3 is located on the ground. A pump body 4 is fixed on the top of the water tank 3. The pier top spraying component 1 and the pier body spraying component 2 are both connected to the water tank 3 through the pump body 4. A stable component 6 that can move up and down is provided on the surface of the concrete pier body 9, and the top of the stable component 6 is fixedly connected to the pier body spraying component 2. Guide components 7 are installed on both sides of the top end of the concrete pier body 9. A driving component 8 is provided to match the guide components 7 and the pier body spraying component 2, and the driving component 8 can drive the pier body spraying component 2 to lift along the concrete pier body 9.

[0029] The pier top spraying component 1 includes a first spraying pipe 101 fixed on the top of the concrete pier body 9, and a plurality of first spray heads 102 are fixed on the lower surface of the first spraying pipe 101. The pier body spraying component 2 includes a second spraying pipe 21 surrounding the outside of the concrete pier body 9, and a plurality of second spray heads 22 are fixed on the inner side of the second spraying pipe 21. Both the first spraying pipe 101 and the second spraying pipe 21 are annular.

[0030] The pier top spraying component 1 is fixed on the top of the concrete pier body 9 to directly spray and cure the top of the concrete pier body 9. The pier body spraying component 2 can move up and down along the concrete pier body 9, so as to comprehensively spray and cure the surface of the concrete pier body 9.

[0031] The water inlet of the pump body 4 is communicated with the inside of the water tank 3 through a pipeline, and the water outlet of the pump body 4 is fixedly connected with two water delivery pipes 5 through a tee. The other ends of the two water delivery pipes 5 are respectively connected to the first spraying pipe 101 and the second spraying pipe 21.

[0032] In this embodiment, the volume of the water tank 3 is at least 5m 3 , and the water in the water tank 3 can be pumped out by the pump body 4 and then pumped into the pier top spraying component 1 and the pier body spraying component 2, so as to spray and cure the top and surface of the concrete pier body 9.

[0033] The stabilizing component 6 includes a C-shaped plate 61 located outside the concrete pier 9. On both sides of the inner wall of the C-shaped plate 61, two conduits 63 are fixed. And a spring 64 is fixedly connected to the inner wall of the conduit 63. The other end of the spring 64 is fixedly connected to a guide rod 65. One end of the guide rod 65 located outside the conduit 63 is equipped with a roller 66. And the roller 66 is in contact with the outer wall of the concrete pier 9. On both sides of the top of the C-shaped plate 61, support rods 62 are fixedly connected. The top ends of the support rods 62 are fixedly connected to the second spray pipe 21.

[0034] Under the extrusion force of the spring 64, the roller 66 will be in close contact with the surface of the concrete pier 9. Therefore, when the second spray pipe 21 of the pier spraying component 2 moves up and down along the concrete pier 9, the C-shaped plate 61 of the stabilizing component 6 will also move synchronously along the concrete pier 9. And because the roller 66 is in close contact with the outer wall of the concrete pier 9, the stability of the second spray pipe 21 when moving up and down can be ensured.

[0035] The guiding component 7 includes a bracket 71 fixed on the upper surface of the concrete pier 9. And a fixed pulley 72 is installed on the top of the bracket 71. The driving component 8 includes a motor 81 located on the ground. The driving shaft of the motor 81 is fixedly connected to a wire reel 82. A steel wire rope 83 is wound around the surface of the wire reel 82. One end of the steel wire rope 83 far from the wire reel 82 bypasses the fixed pulley 72 and is fixedly connected to the second spray pipe 21.

[0036] The fixed pulley 72 plays a guiding role for the steel wire rope 83. By driving the wire reel 82 to rotate through the motor 81, the wire reel 82 can wind or unwind the steel wire rope 83. When the steel wire rope 83 is wound, the steel wire rope 83 will pull the pier spraying component 2 to rise. When the steel wire rope 83 is unwound, the steel wire rope 83 will drive the pier spraying component 2 to descend.

[0037] Working principle: When it is necessary to spray and cure the concrete pier 9, the water in the water tank 3 is pumped out through the pump body 4. Then, the water is respectively pumped into the pier top spraying component 1 and the pier body spraying component 2 by using two water delivery pipes 5. Finally, it is sprayed out from the first spray head 102 and the second spray head 22. The pier top spraying component 1 sprays the top of the concrete pier 9, and the pier body spraying component 2 sprays the surface of the concrete pier 9. When spraying the surface of the concrete pier 9, the motor 81 can be started to rotate forward and reverse alternately. Thus, the steel wire rope 83 is used to drive the pier body spraying component 2 to move up and down along the concrete pier 9, realizing the comprehensive spraying of the surface of the concrete pier 9.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
