[0022] As Figures 1 to 3 shown, a preferred embodiment of the present invention provides a high pier spraying device for spraying operations on the outer surface of the high pier 100.

[0023] A high pier spraying device includes a spraying part 1, a hoisting part 2 and a material pumping part 3. The spraying part 1 includes an annular pipe 11 and a contact guiding wheel 12. The annular pipe 11 is arranged around the outside of the high pier 100. A plurality of spraying ports 112 are arranged on one side of the annular pipe 11 facing the high pier 100. The contact guiding wheel 12 is connected to the annular pipe 11 and abuts against the surface of the high pier 100. The hoisting part 2 is arranged on the top surface of the high pier 100 and connected to the annular pipe 11. The hoisting part 2 can hoist the annular pipe 11 to move along the length direction of the high pier 100. The material pumping part 3 includes a grouting pipe 30 and a material pumping assembly. One end of the grouting pipe 30 is connected and communicated with the annular pipe 11. The material pumping assembly is connected to the grouting pipe 30 and pumps the coating towards the annular pipe 11 through the grouting pipe 30.

[0024] When the above high pier spraying device is in use, the hoisting part 2 is arranged on the top surface of the high pier 100. During the process of the hoisting part 2 hoisting the annular pipe 11 to move along the length direction of the high pier 100, the grouting pipe 30 pumps the coating towards the annular pipe 11, and the coating is finally sprayed from the spraying ports 112 onto the outer surface of the high pier 100 to complete the spraying operation. It can be seen that the use of the present utility model can replace manual work to complete the spraying operation on the outer surface of the high pier 100.

[0025] In this embodiment, the annular pipe 11 includes a plurality of segmented pipes 111. The annular pipe 11 is formed by connecting a plurality of segmented pipes 111 into a ring and the plurality of segmented pipes 111 are communicated. Specifically, the segmented pipe 111 is in a cylindrical shape. An internal threaded hole is opened at one end of the segmented pipe 111. The outer surface of the other end of the segmented pipe 111 is provided with an external thread and the other end of the segmented pipe 111 can be sleeved into the end of another segmented pipe 111 provided with the internal threaded hole, so that the two segmented pipes 111 are connected. The ring formed by connecting a plurality of segmented pipes 111 has the same cross-sectional shape as the cross-section of the high pier 100 to be pre-sprayed on the horizontal plane. A plurality of spraying ports 112 are arranged on one side of each segmented pipe 111 facing the high pier 100. The ring formed by connecting a plurality of segmented pipes 111 has the same cross-sectional shape as the cross-section of the high pier 100 to be pre-sprayed on the horizontal plane, which can enable the segmented pipe 111 to spray the outer surface of the high pier 100 comprehensively.

[0026] In this embodiment, each segmented pipe 111 is detachably provided with a baffle 113. The baffle 113 is used to block the spraying ports 112. Specifically, the baffle 113 is adapted to the length of the segmented pipe 111. The baffle 113 is detachably arranged on one side of the outer surface of the segmented pipe 111 facing the high pier 100 by bolts. When it is not necessary to spray the surface corresponding to a certain segmented pipe 111, when the annular pipe 11 is located at the bottom of the high pier 100, the baffle 113 can be installed on the segmented pipe 111.

[0027] In this embodiment, the abutment guide wheel 12 is installed on one end of a tilting rod 15. Specifically, the tilting rod 15 includes a sleeve 151, a sleeve spring 152, a mounting plate 153 and an abutment tube 154. One end of the sleeve spring 152 is connected to one end of the sleeve 151, the mounting plate 153 is connected to the end of the sleeve spring 152 away from the sleeve 151, one end of the abutment tube 154 is connected to the mounting plate 153, and the other end of the abutment tube 154 is slidably sleeved in the sleeve 151; the abutment guide wheel 12 is installed on the mounting plate 153; a mounting arc plate 155 is provided at the end of the sleeve 151 away from the abutment guide wheel 12, and the mounting arc plate 155 is welded to the annular tube 11. The tilting rod 15 is tilted relative to the surface of the high pier 100, and one end of the tilting rod 15 away from the abutting guide wheel 12 is connected to the annular tube 11. Specifically, there are a plurality of abutting guide wheels 12, which are arranged at intervals along the circumference of the annular tube 11, and one end of the tilting rod 15 away from the abutting guide wheel 12 is connected to the corresponding segmented tube 111. Since the tilting rod 15 is tilted relative to the surface of the high pier 100, when the annular tube 11 moves along the length direction of the high pier 100, the tilting rod 15 can abut the abutting guide wheel 12 against the surface of the high pier 100, so that the annular tube 11 does not move in a large direction relative to the high pier 100. When the abutment guide wheel 12 moves against the surface of the high pier 100, the abutment guide wheel 12 adapts to the changes in the surface unevenness of the high pier 100 and presses against the sleeve spring 152 or relaxes. The sleeve spring 152 undergoes elastic deformation as the abutment guide wheel 12 moves, so that the abutment guide wheel 12 can always move against the surface of the high pier 100.

[0028] In this embodiment, the spraying unit 1 further includes a wireless camera 13, which is installed on the annular tube 11. Specifically, there are a plurality of wireless cameras 13, which are arranged at intervals along the circumference of the annular tube 11. The arrangement of the wireless camera 13 can facilitate the construction worker to observe the spraying effect of the segmented tube 111.

[0029] In this embodiment, the hoisting part 2 includes a hoisting machine 21 and a hoisting rope 22. The hoisting machine 21 is arranged on the top surface of the high pier 100. The hoisting rope 22 is wound on the hoisting machine 21 and one end of the hoisting rope 22 is connected to the annular tube 11. Specifically, there are several hoists 21, which are distributed on the top surface of the high pier 100. One hoisting machine 21 is used to wind up one hoisting rope 22. When the hoisting machine 21 winds up the hoisting rope 22, the annular tube 11 moves along the length direction of the high pier 100.

[0030] In this embodiment, the pump assembly is a grouting machine 31, which is connected to the grouting pipe 30. When the grouting machine 31 is working, the coating can be pumped toward the grouting pipe 30. The use of the grouting pipe 30 is a prior art. During on-site construction, the construction personnel can assemble and adjust the length of the grouting pipe 30 according to the lifting and lowering of the annular pipe 11.

[0031] Principle of use: The principle of use of the high pier spraying device is illustrated by a high pier 100 with four spraying surfaces in this embodiment as follows:

[0032] Device assembly: Prepare four segmented pipes 111. The segmented pipes 111 are made of steel pipes. At the bottom of the high pier 100, the four segmented pipes 111 are respectively corresponding to one spraying surface. The four segmented pipes 111 are sleeved and tightened to obtain an annular pipe 11 in the shape of a square. Spraying openings 112 are drilled on one side of the segmented pipes 111 facing the spraying surface; Prepare four wireless cameras 13, and tie and fix the four wireless cameras 13 at the four corners of the annular pipe 11; Prepare four sling ropes 22 and four winches 21. Drill four through holes 101 corresponding to the four corners of the annular pipe 11 on the top surface of the high pier 100. The sling ropes 22 are made of steel wires. On the top surface of the high pier 100, a pulley 23 is supported by a support rod 24 corresponding to each sling rope 22. The sling ropes 22 are arranged in the pulleys 23. The four sling ropes 22 are respectively lowered from the four through holes 101 to the bottom of the high pier 100, and one ends of the four sling ropes 22 are fixedly connected to the four corners of the annular pipe 11; Prepare two grouting pipes 30. The two grouting pipes 30 are arranged corresponding to two opposite surfaces of the high pier 100. The two grouting pipes 30 are connected to two corresponding segmented pipes 111. Specifically, filling holes are opened on the two corresponding segmented pipes 111, and the grouting pipes 30 are inserted into the filling holes and tied and fixed.

[0033] Spraying operation: The construction workers control the winches 21 on the top surface of the high pier 100 to wind up the sling ropes 22, and the annular pipe 11 moves towards the top surface of the high pier 100. Start the grouting machine 31, and the grouting machine 31 sprays the slurry into the grouting pipes 30. The slurry is sprayed from the spraying openings 112 onto the surface of the high pier 100, and thus the spraying operation of the high pier 100 is completed. When the annular pipe 11 moves below the top surface of the high pier 100 and the spraying operation is completed, the annular pipe 11 can be disassembled and recycled through aerial work.
