Description

Technical Field

[0001] The present invention relates to the technical field of high pier construction, and in particular to an automated cover-type maintenance device for high piers. Background Art

[0002] Pier curing involves spraying and curing the solidified concrete after pouring concrete during bridge pier construction to ensure a stronger and more durable setting. The shape of a pier depends on multiple factors in bridge design, including functional requirements, load conditions, geographic environment, and aesthetic considerations. Common shapes include square, circular, and elliptical, each with its own specific advantages and applications. Square piers are the simplest and most common pier shapes, with a square or nearly square cross-section. These piers provide a larger support area, making them suitable for simple bridge structures.

[0003] Existing maintenance methods for square piers include film maintenance or automated spraying. Film maintenance usually involves wrapping the surface of the pier with plastic film or geotextile, and then spraying the inside. This method requires a large area to be wrapped with plastic film, while existing automated maintenance devices usually utilize a hoisted spray bracket for up and down sliding spraying. The device is driven by a motor, and a hoisting support seat and a drive mechanism are usually pre-installed on the top of the pier.

[0004] Existing film curing requires wrapping a large area with plastic sheeting. Due to the high height of the pier, the plastic film cannot adhere well to the surface of the pier, resulting in a large difference in humidity at different parts of the pier surface during spraying, which makes the spraying of the pier uneven. Mechanical curing uses a mechanical device to slide up and down along the surface of the pier for spraying curing. However, the spraying path of this method is relatively single. Compared with the wrapping of film curing, the dynamic spraying of the mechanical device not only has low spraying efficiency, but also uneven spraying area.

[0005] In view of the above situation, in order to overcome the above technical problems, the present invention designs an automated hood-type maintenance device for high piers, which solves the above technical problems. Summary of the Invention

[0006] The technical purpose to be achieved by the present invention is: the present invention provides an automated cover-type maintenance device for high piers, which achieves multi-layer uniform wrapping of the high pier by installing multiple layers of maintenance components on the surface of the high pier, connecting the maintenance components with maintenance tarpaulins, and connecting the two sides of the maintenance tarpaulins with connecting magnetic strips.

[0007] In order to achieve the above technical objectives, the present invention provides the following technical solutions:

[0008] The present invention provides an automated hood-type maintenance device for high piers, comprising a control unit, which is installed on the top of the high pier; further comprising a maintenance component and a maintenance tarpaulin, wherein the maintenance component is installed on the four side walls of the high pier, and a plurality of the maintenance components are linearly arrayed on the side walls of the high pier; a maintenance tarpaulin is installed on the maintenance component, the maintenance tarpaulin is tightly attached to the side walls of the high pier, and the lower end of the maintenance tarpaulin is connected to the maintenance component below; the maintenance component is divided into a maintenance support frame and a maintenance rotating frame through diagonal alignment, and the maintenance support frame and the maintenance rotating frame are connected by a hinge seat, and the maintenance component connects multiple maintenance tarpaulins up and down through a multi-layer linear arrangement, while the magnetic strips on the sides of the multiple maintenance tarpaulins are close to each other.

[0009] Automated hood-type curing devices for high piers have broad application prospects in my country's infrastructure construction, especially in highway and high-speed rail projects. This curing device significantly improves the curing quality of high concrete piers and shortens the curing cycle, significantly contributing to the development of my country's transportation infrastructure.

[0010] An automated hood-type maintenance system for high piers consists of a control unit, maintenance components, and a maintenance tarpaulin. The control unit, located atop the pier, controls the entire system. The maintenance components are mounted on the pier's four sides. Multiple maintenance components are arranged in a linear array on the pier's sidewalls, forming a complete maintenance system.

[0011] The maintenance tarpaulin is tightly attached to the sidewall of the pier, with its lower end connected to the maintenance assembly below, ensuring its stability and effectiveness. The maintenance assembly is divided into a maintenance support frame and a maintenance rotation frame by diagonal alignment. These two components are connected by a hinged seat, allowing them to flexibly rotate to adapt to different maintenance needs.

[0012] Furthermore, the maintenance components are arranged in a multi-layer linear configuration, connecting multiple maintenance tarpaulins vertically. Magnetic strips on the sides of the tarpaulins draw them together, ensuring a tight connection and enhancing maintenance effectiveness. This automated hood-type maintenance system for high piers not only improves maintenance efficiency and reduces costs, but also offers advantages such as ease of operation, safety, reliability, and adaptability.

[0013] The maintenance assembly includes a maintenance support frame, a maintenance rotating frame and a twisted seat. The maintenance support frame is a right-angled connecting rod structure, and the inner side of the right angle of the maintenance support frame is installed on the side wall of the high pier. The structure of the maintenance rotating frame is the same as that of the maintenance support frame and the two are connected to form a rectangle. The twisted seat is installed at the diagonal connection between the maintenance rotating frame and the maintenance support frame. The twisted seat is in a group of two, and the twisted seats in a group of two are respectively installed at one end of the maintenance support frame and the maintenance rotating frame. There are two groups of twisted seats in total, and the other group of twisted seats is installed at the other end of the maintenance support frame and the maintenance rotating frame; the maintenance tarpaulin is connected to the outside of the maintenance support frame and the maintenance rotating frame through the series rods on the outer sides of the maintenance support frame and the maintenance rotating frame, and the length of the maintenance tarpaulin extending downward does not exceed twice the side length of the maintenance support frame.

[0014] The maintenance support frame and the maintenance rotating frame have the same structural design. During installation, the maintenance support frame is stationary relative to the maintenance rotating frame, while the maintenance rotating frame can be rotated and unfolded around the hinged seat to achieve rapid disassembly and assembly of the maintenance component. Before folding, the maintenance tarpaulin on the maintenance component needs to be stored and wound around the support rod, and then the support rod is removed, and the maintenance component can be folded and disassembled; during installation, the folded maintenance components are overlapped up and down, the maintenance support frame and the maintenance rotating frame are aligned with each other, and the transmission components inside the two are aligned with each other.

[0015] The maintenance support frame includes a supporting angle rod, an adjusting nut, a transmission assembly, an adjusting screw rod and a sliding adjustment rod. A supporting angle rod is provided at a right angle of the maintenance support frame, an adjusting nut is installed on the outer side wall of the supporting angle rod, a transmission assembly is installed on the inner side of the adjusting nut and inside the supporting angle rod, the transmission assembly is connected to one end of the adjusting screw rod, and the other end of the adjusting screw rod is connected to the sliding adjustment rod, and the outer side surface of the sliding adjustment rod is installed on the inner side surface of the supporting angle rod.

[0016] The transmission assembly is connected to one end of the adjustment screw, while the other end of the adjustment screw is connected to a sliding adjustment rod. The outer surface of the sliding adjustment rod is mounted on the inner surface of the support angle bar. This structure of the maintenance support frame achieves adjustment and support for the maintenance tarpaulin through the arrangement of the support angle bar and adjustment nut, and the coordinated action of the transmission assembly, adjustment screw, and sliding adjustment rod, ensuring the stability and reliability of the maintenance device.

[0017] The lower end face of the supporting angle bar is installed with a supporting guide roller, and the lower end face of the sliding adjustment rod is installed with a sliding guide roller. The circular end faces of the supporting guide roller and the sliding guide roller coincide with each other, and the distance between the supporting guide roller and the lower end face of the supporting angle bar does not exceed the side height value of the supporting angle bar.

[0018] Both the supporting guide roller and the sliding guide roller are used to guide and extend the maintenance tarpaulin. The maintenance tarpaulin extends from the support rod to the supporting guide roller and the sliding guide roller, and then the maintenance tarpaulin extends downward around the supporting guide roller and the sliding guide roller. According to the installation position of the supporting guide roller and the sliding guide roller, the distance of the maintenance tarpaulin inward from the surface of the high pier can be adjusted by the supporting guide roller and the sliding guide roller. Since the supporting guide roller and the sliding guide roller together guide the maintenance tarpaulin, the installation positions of the two need to be consistent.

[0019] The transmission assembly includes a rotating shaft, a transmission spur gear, a transmission bevel gear, a screw bevel gear, an auxiliary bevel gear, an auxiliary spur gear and an auxiliary shell. The rotating shaft is installed inside the supporting angle rod. The adjusting nut is connected to the transmission spur gear through the rotating shaft. The transmission spur gear is connected to the transmission bevel gear and the auxiliary bevel gear in sequence through the rotating shaft. The transmission spur gear and the transmission bevel gear rotate coaxially and at the same frequency. The screw bevel gear is respectively meshed with the transmission bevel gear and the auxiliary bevel gear. One end of the screw bevel gear is connected to an adjusting screw. The auxiliary bevel gear is installed coaxially with the rotating shaft. The transmission spur gear is meshed with the auxiliary spur gear. The auxiliary spur gear is connected to the auxiliary shell on the outer side of the supporting angle rod.

[0020] Specifically, the rotating shaft is rotatably installed inside the supporting angle rod through the bearing, and the adjusting nut connected to the rotating shaft drives the transmission spur gear and the transmission bevel gear to rotate coaxially and at the same frequency in sequence, while the auxiliary bevel gear side rotates freely. The auxiliary bevel gear can rotate freely on the rotating shaft, so the rotation of the screw bevel gear will drive the auxiliary bevel gear to rotate, thereby achieving the balance and stability of the screw bevel gear; the screw bevel gear is respectively engaged with the transmission bevel gear and the auxiliary bevel gear, and one end of the screw bevel gear is connected to the adjusting screw.

[0021] At the same time, the coordinated action of the adjusting nut, bevel gear, and screw allows for flexible adjustment of the sliding lever, ensuring full coverage and efficient maintenance. Overall, the transmission assembly provides efficient and precise motion control, strongly supporting the reliable adjustment and high-quality maintenance of the automated hood-type maintenance system for high piers.

[0022] A minor-arc auxiliary groove is defined within the auxiliary housing and on the sidewall supporting the angle rod. The minor-arc angle of the auxiliary groove is less than 90 degrees. The auxiliary rod within the auxiliary groove is inwardly connected to an auxiliary spur gear. The auxiliary housing encases and protects the auxiliary groove and auxiliary rod. The outer surface of the auxiliary housing resembles the outer end of the auxiliary rod, further stabilizing the sliding of the auxiliary rod within the auxiliary groove. The overall shape of the auxiliary housing is the same as that of the auxiliary groove, i.e., it is arc-shaped.

[0023] A hinge seat is installed at the front end of the sliding adjustment rod, and the cross-sectional angle of the hinge seat is 135 degrees. A lead screw nut is installed inside the rear end of the sliding adjustment rod. A plurality of limit pins are installed through the position of the lead screw nut on the sliding adjustment rod, and the limit pins are tangent to the end faces of both sides of the lead screw nut.

[0024] The hinged seat at the front end of the sliding adjustment rod is an articulated mechanism that realizes the folding and unfolding of the maintenance support frame and the maintenance rotating frame. Since the maintenance component is a rectangle as a whole, the connection between the hinged seat of the maintenance support frame and the maintenance rotating frame has a certain rotation angle. Through analysis and practice, it can be obtained that the front end angle of the hinged seat is 135 degrees, which can realize the folding and unfolding of the maintenance support frame and the maintenance rotating frame.

[0025] A screw sleeve is coaxially mounted on the inner end of the screw nut. The screw sleeve has an interference fit with the adjustment screw, and the length of the screw sleeve is greater than half the length of the sliding adjustment rod. The sliding adjustment rod is connected to the support angle rod in a relative sliding manner, that is, the sliding adjustment rod slides within the support angle rod. Specifically, the sliding adjustment rod achieves linear sliding through the rotation of the adjustment screw and the screw nut thereon. The adjustment screw requires a certain amount of support within the internal cavity of the sliding adjustment rod. Otherwise, when the adjustment screw slides to the longest position of the maintenance support frame, the connection strength of the adjustment screw is low, and the adjustment screw is prone to falling off or even breaking.

[0026] The upper end of the maintenance tarpaulin is installed on the maintenance support frame through a support rod, a water inlet pipe is installed in the support rod, the maintenance tarpaulin is a double-layer structure and pleated overlapping tarpaulins are connected on both sides, and connecting magnetic strips are installed on the outer side of the overlapping tarpaulin.

[0027] The water inlet pipe runs through the maintenance tarpaulin horizontally, and multiple diversion pipes are distributed longitudinally of the maintenance tarpaulin. Multiple diversion pipes are connected in parallel with the water inlet pipe. Multiple diversion holes are opened longitudinally in the diversion pipe, and the apertures of the multiple diversion holes gradually decrease from top to bottom.

[0028] In maintenance operations, rationally utilizing water resources and achieving environmentally friendly practices are crucial. Spraying is a common method, aiming to reduce water waste and improve maintenance effectiveness. Spraying utilizes diverter pipes to distribute water efficiently to the areas requiring maintenance.

[0029] However, in practice, water flow is unevenly distributed above and below the diversion holes, resulting in uneven maintenance of high piers and significant water waste. To address this issue, spraying operations need to be optimized. First, the diversion pipes must be rationally designed to ensure stable water flow and minimize losses. Second, the amount and angle of the spray should be adjusted according to the actual conditions of the maintenance area to achieve more uniform operation.

[0030] The beneficial effects of the present invention are as follows:

[0031] 1. The present invention installs multiple uniformly linear maintenance components on the surface of the high pier. When the maintenance components are deployed, the maintenance tarpaulin extends downward to the next maintenance component, and then the maintenance tarpaulin is evenly and evenly spread on the square high pier surface. Each maintenance component is sprayed with water through the water inlet pipe inside the maintenance tarpaulin on it, thereby achieving uniform maintenance of the high pier.

[0032] 2. The present invention divides the maintenance component into a maintenance support frame and a maintenance rotating frame, which are hinged to each other through a hinge seat. When disassembling, the maintenance support frame and the maintenance rotating frame are rotated and overlapped to achieve rapid storage of the maintenance component, and they are quickly unfolded and installed during installation, thereby achieving rapid disassembly and assembly of the maintenance component.

[0033] 3. The present invention has multiple diversion holes on the diversion pipe inside the maintenance tarpaulin. The diversion holes are arranged linearly up and down and the aperture at the bottom is smaller, thereby reducing the downward spray flow of the spray water, making the use of the spray water more environmentally friendly, and the water flow spraying from top to bottom can further ensure uniform spraying.

DETAILED DESCRIPTION

[0047] In order to better understand the above technical solution, the above technical solution will be described in detail below with reference to the accompanying drawings and specific implementation methods.

[0048] like Figures 1 to 10 As shown, the present invention provides an automated hood-type maintenance device for high piers, comprising a control unit 1, which is installed on the top of the high pier; further comprising a maintenance component 2 and a maintenance tarpaulin 3, wherein the maintenance component 2 is installed on the four side walls of the high pier, and a plurality of the maintenance components 2 are linearly arrayed on the side walls of the high pier; a maintenance tarpaulin 3 is installed on the maintenance component 2, wherein the maintenance tarpaulin 3 is tightly attached to the side walls of the high pier and the lower end of the maintenance tarpaulin 3 is connected to the maintenance component 2 below; the maintenance component 2 is divided into a maintenance support frame 21 and a maintenance rotating frame 22 by diagonal alignment, and the maintenance support frame 21 and the maintenance rotating frame 22 are connected by a hinge seat, and the maintenance component 2 connects multiple pieces of the maintenance tarpaulins 3 up and down through a multi-layer linear arrangement, while the magnetic strips on the sides of the multiple pieces of the maintenance tarpaulins 3 are close to each other.

[0049] The maintenance assembly 2 is divided into a maintenance support frame 21 and a maintenance rotating frame 22, which are connected by a hinge. Multiple maintenance tarpaulins 3 are arranged linearly in multiple layers and connected vertically, with magnetic strips on their sides aligning with each other. This design enables automated, hood-style maintenance of high piers. The flexible connection of the maintenance tarpaulins 3 ensures adequate moisture retention and structural stability. Furthermore, the simplified structure of the device facilitates installation and removal.

[0050] The control component can regulate the water supply cycle and water supply mode of the external water supply equipment. The control component includes a temperature and humidity controller and an automatic spray or steam delivery controller. The temperature and humidity controller controls the temperature and humidity of the concrete surface inside the curing tarpaulin and provides signals for automatic spraying or delivery. The automatic spray or steam delivery controller realizes automatic control of spraying or steam.

[0051] like Figures 2 to 5 As shown, the maintenance assembly 2 includes a maintenance support frame 21, a maintenance rotating frame 22 and a twisting seat 23. The maintenance support frame 21 is a right-angled connecting rod structure. The inner side of the right angle of the maintenance support frame 21 is installed on the side wall of the high pier. The structure of the maintenance rotating frame 22 is the same as that of the maintenance support frame 21 and the two are connected to form a rectangle. The twisting seat 23 is installed at the diagonal connection between the maintenance rotating frame 22 and the maintenance support frame 21. The twisting seat 23 is in a group of two, and the two are connected. A group of twisted seats 23 are respectively installed at one end of the maintenance support frame 21 and the maintenance rotating frame 22. There are two groups of twisted seats 23, and the other group of twisted seats 23 is installed at the other end of the maintenance support frame 21 and the maintenance rotating frame 22; the maintenance tarpaulin 3 is connected to the outside of the maintenance support frame 21 and the maintenance rotating frame 22 through the series rods on the outer side of the maintenance support frame 21 and the maintenance rotating frame 22, and the downward extension length of the maintenance tarpaulin 3 does not exceed twice the side length of the maintenance support frame 21.

[0052] The maintenance tarpaulin 3 is divided into four pieces, and the four maintenance tarpaulins 3 are correspondingly installed on the support rods 31 on the outside of the maintenance component 2. The maintenance tarpaulin 3 extends downward and is laid flat on the surface of the high pier, so that the high pier is wrapped. When spraying, the surface of the high pier can be evenly maintained. However, when the maintenance tarpaulin 3 is extended too long, the maintenance tarpaulin 3 has a certain elasticity. It is difficult for the overly long maintenance tarpaulin 3 to smoothly cover the surface of the high pier. Under the interference of external environment such as air flow and rain at high altitudes, the overly long maintenance tarpaulin 3 is easily blown up or lifted, thereby affecting the fit between the maintenance tarpaulin 3 and the high pier; therefore, the length of the maintenance tarpaulin 3 extending downward does not exceed twice the side length of the maintenance support frame 21, which can ensure that after the maintenance tarpaulin 3 extends downward to a certain length, the next group of maintenance support frames 21 can promptly fix and connect the maintenance tarpaulin 3, thereby ensuring that the maintenance tarpaulin 3 is evenly and tightly covered on the surface of the high pier.

[0053] like Figures 3 to 6 As shown, the maintenance support frame 21 includes a support angle bar 211, an adjusting nut 212, a transmission assembly 213, an adjusting screw rod 214 and a sliding adjustment rod 215. A support angle bar 211 is provided at a right angle of the maintenance support frame 21, and an adjusting nut 212 is installed on the outer wall of the support angle bar 211. A transmission assembly 213 is installed on the inner side of the adjusting nut 212 and inside the support angle bar 211. The transmission assembly 213 is connected to one end of the adjusting screw rod 214, and the other end of the adjusting screw rod 214 is connected to the sliding adjustment rod 215. The outer side surface of the sliding adjustment rod 215 is installed on the inner side surface of the support angle bar 211.

[0054] The maintenance support frame 21 has the same structure as the maintenance rotating frame 22, so only the characteristics of the maintenance support frame 21 are introduced here, and the maintenance rotating frame 22 can be obtained similarly; the maintenance support frame 21 is composed of a support angle bar 211, an adjusting nut 212, a transmission assembly 213, an adjusting screw rod 214 and a sliding adjustment rod 215, wherein the support angle bar 211 is the main support frame of the entire maintenance support frame 21, that is, it determines that the entire maintenance support frame 21 is a right angle, and the adjusting nut 212 is used to adjust the transmission assembly 213, and then adjust the sliding adjustment rod 215 to slide and retract in the support angle bar 211, thereby realizing the length adjustment of the maintenance support frame 21.

[0055] like Figure 3 and Figure 4 As shown, the lower end surface of the supporting angle bar 211 is installed with a supporting guide roller 2111, and the lower end surface of the sliding adjustment rod 215 is installed with a sliding guide roller 2151. The positions of the circular end surfaces of the supporting guide roller 2111 and the sliding guide roller 2151 coincide with each other, and the distance between the supporting guide roller 2111 and the lower end surface of the supporting angle bar 211 does not exceed the side height value of the supporting angle bar 211.

[0056] The circular end surfaces of the supporting guide roller 2111 and the sliding guide roller 2151 coincide with each other, which makes the supporting guide roller 2111 and the sliding guide roller 2151 at the same horizontal position. The guide roller is divided into the supporting guide roller 2111 and the sliding guide roller 2151, and is respectively installed on the supporting angle bar 211 and the sliding adjustment bar 215, because the supporting angle bar 211 and the sliding adjustment bar 215 both have the characteristic of relative sliding, and the supporting guide roller 2111 and the sliding guide roller 2151 are both installed on the two. In order to make the maintenance tarpaulin 3 have a certain fitting spacing, the supporting guide roller 2111 and the sliding guide roller 2151 are installed on the supporting assembly, and the distance between the two is Represents the sliding stroke of the support angle bar 211 and the sliding adjustment rod 215; further, when the support guide roller 2111 and the sliding guide roller 2151 guide the maintenance tarpaulin 3, the maintenance tarpaulin 3 extends inward and downward. At this time, the maintenance tarpaulin 3 is guided by the guide rollers, and the maintenance tarpaulin 3 will be bent, and this bending angle can be controlled by adjusting the downward extension length of the support guide roller 2111 and the sliding guide roller 2151, that is, the spacing value between the support guide roller 2111 and the lower end face of the support angle bar 211 will affect the bending angle of the maintenance tarpaulin 3. An excessively large spacing value makes the extension angle of the maintenance tarpaulin 3 smaller, and there will be a larger gap between the maintenance tarpaulin 3 and the high pier, thereby affecting the maintenance uniformity.

[0057] like Figure 6 and Figure 7 As shown, the transmission assembly 213 includes a rotating shaft 2131, a transmission spur gear 2132, a transmission bevel gear 2133, a screw bevel gear 2134, an auxiliary bevel gear 2135, an auxiliary spur gear 2136 and an auxiliary shell 2137. The rotating shaft 2131 is installed inside the supporting angle bar 211. The adjusting nut 212 is connected to the transmission spur gear 2132 through the rotating shaft 2131. The transmission spur gear 2132 is sequentially connected to the transmission bevel gear 2133 and the auxiliary bevel gear through the rotating shaft 2131. Wheel 2135, the transmission spur gear 2132 and the transmission bevel gear 2133 rotate coaxially and at the same frequency, the screw bevel gear 2134 is respectively engaged with the transmission bevel gear 2133 and the auxiliary bevel gear 2135, one end of the screw bevel gear 2134 is connected to the adjusting screw 214, the auxiliary bevel gear 2135 is installed to rotate coaxially with the rotating shaft 2131, the transmission spur gear 2132 is engaged with the auxiliary spur gear 2136, and the auxiliary spur gear 2136 is connected to the auxiliary shell 2137 on the outer side of the supporting angle rod 211.

[0058] The rotation of the adjustment nut 212 drives the rotating shaft 2131, which in turn drives the transmission spur gear 2132 and the transmission bevel gear 2133. The engagement of the transmission bevel gear 2133 causes the side screw bevel gear 2134 to rotate. Because the auxiliary bevel gear 2135 is not connected to the rotating shaft 2131 via a keyway but is instead connected by rotation, the screw bevel gear 2134 drives the auxiliary bevel gear 2135 to rotate, causing the auxiliary bevel gear 2135 to rotate in the opposite direction to the driving bevel gear. The rotation of the screw bevel gear 2134 drives the connected adjustment screw 214 to rotate. The adjustment screw 214 rotates within the screw nut 216, thereby driving the sliding adjustment rod 215 to slide and retract. The transmission spur gear 2132 drives the auxiliary spur gear 2136 to rotate, and then the rotation of the auxiliary spur gear 2136 drives the auxiliary spur gear 2136 in the maintenance rotating frame 22 to rotate, and finally drives the transmission assembly 213 in the maintenance rotating frame 22 to rotate, thereby realizing rapid and synchronous adjustment of the length of the sliding adjustment rod 215 in the maintenance rotating frame 22.

[0059] It is worth noting that since the transmission spur gear 2132 in the maintenance support frame 21 is driven by the auxiliary spur gear 2136, after the auxiliary spur gear 2136 in the maintenance rotating frame 22 is engaged with the auxiliary spur gear 2136 in the maintenance support frame 21, the transmission spur gear 2132 of the maintenance support frame 21 and the transmission spur gear 2132 on the maintenance rotating frame 22 rotate in opposite directions. In short, since the maintenance support frame 21 and the maintenance rotating frame 22 are symmetrically arranged when folded, the transmission between the two is also opposite. In order to enable the adjusting nut 212 on the rotating maintenance support frame 21 to synchronously drive the sliding adjustment rod 215 on the maintenance rotating frame 22 for synchronous adjustment, the adjusting screw 214 on the maintenance support frame 21 and the adjusting screw 214 on the maintenance rotating frame 22 are opposite to each other, that is, the screw threads on the adjusting screws 214 on the two are opposite.

[0060] like Figure 5 and Figure 6 As shown, a minor-arc-shaped auxiliary groove 2138 is defined within the auxiliary housing 2137 and on the sidewall of the support angle bar 211. The minor-arc angle of the auxiliary groove 2138 is less than 90 degrees. An auxiliary rod 2139 within the auxiliary groove 2138 is inwardly connected to an auxiliary spur gear 2136. The auxiliary rod 2139 slides within the auxiliary groove 2138, thereby causing the auxiliary spur gear 2136 to slide along the auxiliary groove 2138. Because the minor-arc of the auxiliary groove 2138 is coaxial with the tooth tip arc of the transmission spur gear 2132, the auxiliary spur gear 2136 will always mesh with the transmission spur gear 2132 as it rotates along the auxiliary groove 2138. Furthermore, the minor-arc angle of the auxiliary groove 2138 should not be too large, as otherwise, the strength of the sidewall of the support angle bar 211 will be reduced, and the stability of the auxiliary spur gear 2136 will also be compromised.

[0061] like Figure 8 and Figure 9 As shown, a hinge seat 23 is installed at the front end of the sliding adjustment rod 215, and the cross-sectional angle of the hinge seat 23 is 135 degrees. A screw nut 216 is installed inside the rear end of the sliding adjustment rod 215, and a plurality of limiting pins 217 are installed through the position of the screw nut 216 on the sliding adjustment rod 215, and the limiting pins 217 are tangent to the end faces of both sides of the screw nut.

[0062] The screw nut 216 is embedded in the cylindrical cavity of the sliding adjustment rod 215, that is, the outer circular contour of the screw nut 216 is installed coaxially and tangentially with the cavity of the sliding adjustment rod 215, and the screw nut needs to be fixed inside the sliding adjustment rod 215, that is, the screw nut 216 is stationary relative to the adjustment screw 214, and two end surfaces are opened on the outside of the screw nut 216. Four limiting pins 217 are passed through the sliding adjustment rod 215 to limit the two opposite outer end surfaces of the screw nut 216 in the circumferential rotation direction.

[0063] A screw sleeve 218 is coaxially mounted on the inner end of the screw nut 216. This sleeve 218 forms an interference fit with the adjustment screw 214, and its length is greater than half the length of the sliding adjustment rod 215. The adjustment screw 214 is mounted within the sleeve 218 with an interference fit. While enabling linear sliding of the adjustment screw 214, the sleeve 218 provides wrapping and protection for the screw. To prevent wear caused by sliding friction, lubricant should be regularly added to the sleeve 218.

[0064] Since the interior of the sliding adjustment rod 215 is hollowed out, the weight of the entire maintenance mechanism can be kept light. While the screw sleeve 218 supports the adjustment screw 214, the adjustment screw 214 also slides in the cavity inside the sliding adjustment rod 215. In order to ensure the connection strength between the sliding adjustment rod 215 and the supporting angle rod 211, the length of the screw sleeve 218 is greater than half of the length of the sliding adjustment rod 215, thereby ensuring that the screw sleeve 218 has a sufficiently strong connection ability, thereby improving the adjustment stability of the maintenance component 2

[0065] like Figure 10 As shown, the upper end of the maintenance tarpaulin 3 is installed on the maintenance support frame 21 through a support rod 31, and a water inlet pipe 32 is installed in the support rod 31. The maintenance tarpaulin 3 is a double-layer structure and pleated overlapping tarpaulins 33 are connected on both sides. The outer side of the overlapping tarpaulin 33 is installed with a connecting magnetic strip 331.

[0066] The maintenance tarpaulin 3 supplies water to the diversion pipe 321 inside the double-layer structure through the water inlet pipe 32 at the upper end. In order to close the seams on both sides of the maintenance tarpaulin 3, pleated overlapping tarpaulins 33 are provided on both sides of the maintenance tarpaulin 3. The overlapping tarpaulin 33 stretches itself by stretching the pleats and then connects to another maintenance tarpaulin 3. Flexible connecting magnetic strips 331 are also installed on the edges of the overlapping tarpaulin 33, so that the connecting magnetic strips 331 are attached to each other to achieve the attachment of two adjacent maintenance tarpaulins 3.

[0067] like Figure 10 As shown, the water inlet pipe 32 passes through the maintenance tarpaulin 3 horizontally, and multiple diversion pipes 321 are distributed longitudinally of the maintenance tarpaulin 3. Multiple diversion pipes 321 are connected in parallel with the water inlet pipe 32. The diversion pipe 321 is longitudinally provided with multiple diversion holes 322, and the apertures of the multiple diversion holes 322 gradually decrease from top to bottom.

[0068] The rational use of water resources during spraying enables environmentally friendly maintenance operations. According to the characteristics of spraying, when diverting and spraying through the diverter pipe 321, the diverter hole 322 on the diverter pipe 321 sprays. The water flow from the upper diverter hole 322 will flow to the lower diverter hole 322, while the lower diverter hole 322 will also spray. In this way, the water flow at the lower end is larger, the maintenance of the high pier is uneven, and water resources are wasted. The diverter holes 322 have different upper and lower apertures. The upper diverter hole 322 has a larger aperture, which means a larger spray water flow; while the lower diverter hole 322 has a smaller aperture, so the spray water flow is relatively small. This design enables the diverter hole 322 to evenly distribute the spray water flow to the upper and lower levels of the high pier according to actual needs.

[0069] During the working process of the present invention, the construction personnel first fold and overlap the maintenance support frame 21 and the maintenance rotating frame 22 of the maintenance component 2, and align the transmission components 213 in the maintenance support frame 21 and the maintenance rotating frame 22 with each other, that is, the auxiliary spur gears 2136 inside the transmission components 213 of the two correspond to each other, and the construction personnel adjust the position of the auxiliary rod 2139 in the auxiliary groove 2138, and then the auxiliary spur gear 2136 at the front end of the auxiliary rod 2139 follows the sliding adjustment, and the auxiliary spur gear 2136 on the maintenance support frame 21 and the auxiliary spur gear 2136 on the maintenance rotating frame 22 are adjusted to engage with each other, and then, the construction personnel rotate the adjusting nut 212 with the hexagonal nut wrench, and the rotation of the adjusting nut 212 drives the rotating shaft 2131 inside the rotating component to transmit, and then drives the transmission spur gear 2132 and the transmission bevel gear 2133 to rotate, and the transmission bevel gear 2133 engages and drives The side screw bevel gear 2134 rotates, and since the auxiliary bevel gear 2135 is not connected to the rotating shaft 2131 through a keyway but is connected in rotation, the screw bevel gear 2134 will drive the auxiliary bevel gear 2135 to rotate, and the auxiliary bevel gear 2135 and the transmission bevel gear 2133 rotate in the opposite direction; the rotation of the screw bevel gear 2134 drives the connected adjusting screw 214 to rotate, and the adjusting screw 214 rotates in the screw nut 216, thereby driving the sliding adjustment rod 215 to slide and retract; the transmission spur gear 2132 drives the meshing auxiliary spur gear 2136 to rotate, and then the auxiliary spur gear 2136 rotates to drive the auxiliary spur gear 2136 inside the maintenance rotating frame 22 to rotate, thereby driving the transmission assembly 213 in the maintenance rotating frame 22 to rotate and adjust the length of the sliding adjustment rod 215 in the maintenance rotating frame 22, thereby realizing synchronous adjustment of the maintenance support frame 21 and the maintenance rotating frame 22;

[0070] The maintenance support frame 21 and the maintenance rotating frame 22 with adjusted length and size can be unfolded through the hinge seat 23 to form a square maintenance component 2, and put on the outside of the square high pier. The construction personnel fix the maintenance component 2 on the high pier by pre-drilling or screw clamping; furthermore, the construction personnel can remove the hinge seat 23 of the adjusted maintenance support frame 21 and the maintenance rotating frame 22, and then splice them on the outer surface of the high pier, so as to achieve rapid installation and positioning; after installing multiple maintenance components 2 at equal intervals in sequence, the construction personnel install the maintenance tarpaulin 3 on the four sides of the maintenance component 2 through the support rod 31, and the maintenance tarpaulin 3 moves inward along the sliding guide roller 2151 close to the surface of the high pier and extends downward to the next maintenance component 2 and is fixed on the next maintenance component 2. The construction personnel ensure that the maintenance tarpaulin 3 stretches smoothly and the internal pipes are intact and unobstructed;

[0071] Then the construction workers pull the overlapping tarpaulins 33 on both sides of the maintenance tarpaulin 3 to unfold, so that the sides of the two adjacent maintenance tarpaulins 3 are in contact with each other, and then the connecting magnetic strips 331 on the sides of the overlapping tarpaulins 33 are adhered to each other due to the magnetic force, so that the sides of the two adjacent maintenance tarpaulins 3 are tightly closed to each other, thereby realizing the cover-like wrapping of the high pier; finally, the external water pipes are connected to the water inlet pipe 32 in turn, and the water flows through the water inlet pipe 32 into the multiple diversion pipes 321, and then the water in the diversion pipe 321 is sprayed out from the diversion hole 322. Since the upper and lower apertures of the diversion hole 322 are different, the upper diversion hole 322 has a larger aperture and a larger spray water flow, while the lower spray water flow is smaller, thereby realizing the rational use of the spray flow.
