[0032] See also Figure 1-Figure 2 The pier column 1 maintenance device of the utility model has a main structure including a pier top hanger 2 and a lifting truss 4. The pier top hanger 2 is fixedly installed on the top of the pier column 1. The lifting truss 4 is connected to the pier top hanger 2 through a steel wire rope 3 and is arranged on the periphery of the pier column 1. During specific use, the lifting truss 4 can be lifted and moved relative to the pier top hanger 2 in the vertical direction of the pier column 1.
[0033] A spray pipe 10 is provided on the lifting truss 4, and a nozzle 5 is provided on the spray pipe 10. The spray pipe 10 and the nozzle 5 can move up and down synchronously with the lifting truss 4, and can spray during the lifting and moving process, and the spray water is delivered to the outer wall of the pier 1 in the form of splashing, thereby realizing the maintenance of the cast concrete structure of the pier 1.
[0034] The lifting and lowering movement of the lifting truss 4 relative to the pier top hanger 2 is specifically accomplished by a winch mechanism, which is arranged on the pier top hanger 2, and the wire rope 3 is connected to the winch mechanism. Under the action of the winch mechanism, the wire rope 3 can be retracted and released, and then the movement of the lifting truss 4 is controlled by the retraction and release of the wire rope 3.
[0035] The maintenance device in the utility model is still based on the basic level of watering maintenance. By setting a water tank 7 at the bottom of the pier 1 and installing a water pump 9 in the water tank 7, the water in the water tank 7 is pressurized and transported upward, and finally sprayed onto the poured concrete of the pier 1 through the sprinkler 5.
[0036] Based on the above-mentioned spraying maintenance form, the spraying direction of the nozzle 5 is set toward the pier 1, and can be directly facing the side wall of the pier 1, or can be tilted upward or downward to achieve the purpose of spraying water onto the surface of the pier 1.
[0037] The water outlet of the water pump 9 is connected to a water hose 6 , which is connected to a spray pipe 10 . The water in the water tank 7 is pressurized and transported to the spray pipe 10 of the lifting truss 4 through the water hose 6 .
[0038] The water delivery hose 6 has a certain layout flexibility, can be flexibly bent, and can adapt to the water delivery process by following the lifting and lowering movement of the lifting truss 4. In a specific setting form, the delivery hose can be a rubber tube with a certain pressure bearing capacity.
[0039] The pier column 1 maintenance device of the utility model can evenly spray and maintain the poured concrete of the pier column 1 during the vertical movement of the lifting truss 4, thereby improving the maintenance effect of the existing artificial sprinkling.
[0040] In one specific embodiment, the hoisting mechanism includes a hoisting motor 11 , and the lifting truss 4 is lifted and lowered relative to the pier top hanger 2 under the drive of the hoisting motor 11 .

[0042] After the time relay reaches the designated spraying time, the water pump 9 and the winch motor 11 are turned on. The high-lift water pump 9 draws water from the water tank 7 and delivers it to the spray pipe 10 through the water hose 6. The spray pipe 10 is connected to the nozzle 5. The nozzle 5 sprays water on the surface of the pier 1 and simultaneously performs the lifting action of the lifting truss 4 to complete the dynamic spraying process. After the spraying time reaches the predetermined time, the time relay turns off the water pump 9 switch to stop spraying water and stops the lifting action.
[0043] The pier top hanger 2 includes an annular bracket, and the lifting truss 4 is arranged around the outside of the pier 1. The annular truss enables the sprinkler 5 to spray on the outside of the pier 1. At least a part of the annular bracket protrudes from the side wall of the pier 1. The wire rope 3 is suspended on the protruding part, and the lifting truss 4 can be hung on the outside of the pier 1 through the wire rope 3.
[0044] The output end of the hoisting motor 11 is connected to a hoisting shaft 12, and the end of the hoisting shaft 12 is arranged at a protruding portion of the annular bracket relative to the pier 1, and the end of the hoisting shaft 12 is supported and installed by a bearing seat, so that the hoisting shaft 12 can obtain good and reliable operating conditions. The root of the wire rope 3 is connected to the hoisting shaft 12, and the retraction and release of the wire rope 3 can be controlled by the rotation of the hoisting shaft 12, thereby further controlling the vertical displacement movement of the lifting truss 4.
[0045] See also Figure 2 In terms of the specific arrangement of the steel wire ropes 3, in order to enable the lifting truss 4 to be stably lifted and lowered, the steel wire ropes 3 include two groups, which are respectively arranged on both sides of the pier 1, and each group of the steel wire ropes 3 includes a Y-shaped main steel wire rope 31 and a branch steel wire rope 32.
[0046] From the connection angle of the main steel wire rope 31 and the branch steel wire rope 32, the root of the main steel wire rope 31 is connected to the winch shaft 12, the roots of the two branch steel wire ropes 32 are connected to the bottom end of the main steel wire rope 31, and the ends of the branch steel wire ropes 32 are connected to the corners of the annular truss, which can form a strong and reliable lifting relationship to ensure the lifting stability of the lifting truss 4, and at the same time enable the lifting truss 4 to move while maintaining a horizontal state.
[0047] From the perspective of transmission, in order to reduce costs, the driving component in the utility model includes a set, the winch shaft 12 includes two, the output end of the winch motor 11 is connected to a changing transmission mechanism, the changing transmission mechanism includes a bevel gear arranged between the output shaft of the winch motor 11 and the winch shaft 12, which can change the transmission direction of the rotating shaft through the bevel gear when the winch motor 11 rotates, thereby driving the two winch shafts 12 to rotate through the winch motor 11.
[0048] The utility model does not limit the number of hoisting mechanisms and hoisting shafts 12, and two sets of hoisting motors 11 can also be provided, so that each set of hoisting motors 11 corresponds to the retraction and extension of the main steel wire rope 31 arranged opposite thereto, thereby completing the synchronous retraction and extension action.
[0049] Furthermore, the annular truss includes an upper cross bar, a lower cross bar and a vertical bar, and the spray pipe 10 includes a spray hard pipe connected to the upper cross bar. A three-way pipe is arranged between the spray hard pipe and the water supply hose 6, which can directly transport the spray water transmitted by the water pump 9 through the water supply hose 6 into the spray hard pipe.
[0050] In order to facilitate the extraction of water from the water tank 7 , the water pump 9 includes a high-lift submersible pump 9 installed in the water tank 7 , and the water delivery hose 6 is connected between the submersible pump 9 and the three-way pipe to meet the high-lift requirement of the water pump 9 .
[0051] The spray pipe 10 includes a ring-shaped pipe with multiple spray pipe sections 10 interconnected, which can be adapted to the connection and installation of the ring truss. From the perspective of ensuring sufficient spraying, there are multiple nozzles 5, and the multiple nozzles 5 are evenly spaced on each spray pipe section 10. The distance between two adjacent nozzles 5 is 50 cm, which can form a uniform spraying state and reduce spraying dead angles.
[0052] It should be noted that the pier top support and the lifting truss 4 in the present invention are both integral structures, which can not only simplify on-site assembly but also facilitate mobile installation and transportation.
[0053] The pier top hanger 2 is used to install and position the lifting truss 4, thereby improving the construction accuracy and the quality of the spraying.
[0054] By controlling the running time and duration of the high-lift submersible pump 9 and the winch motor 11, the spraying time, duration and lifting movement time can be better guaranteed, the dynamic spraying state can be better achieved, and the quality of maintenance can be improved.
