[0016] Embodiment 1 like Figure 1 , Figure 2As shown, the present invention provides an automatic cleaning method for the outer formwork of a smart hanging basket. Before the construction of the next bridge segment, the outer formwork of the hanging basket is cleaned by a processing device, the processing device includes a three-axis motion slide and a processing unit, the three-axis motion slide includes a Y-axis motion slide 2, an X-axis motion slide 1 and a Z-axis motion slide 3, the processing unit includes an integrated block 6, which is hinged to the bottom end of the Z-axis motion slide 3, and an electric push rod is provided on the integrated block 6. The fixed end of the electric push rod is embedded in the interior of the integrated block 6, and the free end extends out of the outside of the integrated block 6 and is hinged to the fixed part of the pneumatic grinder. The integrated block 6 is also embedded with a purge gun 8, a high-pressure water gun 9 for flushing and a spray gun 10 for spraying a release agent; The automatic cleaning method of the outer template of the smart hanging basket specifically includes the following steps: S1, install the Y-axis motion slide 2 on the main structure system of the hanging basket through the bracket, wherein the Y-axis motion slide 2 is arranged along the horizontal direction of the bridge, the X-axis motion slide 1 is arranged along the longitudinal direction of the bridge, and the Z-axis motion slide 3 is arranged along the vertical direction of the bridge and is located on the inner side of the outer template of the hanging basket; S2, taking the top of the left side of the hanging basket outer template (the side of the hanging basket outer template away from the constructed bridge section) as the initial reference position, driving the Z-axis motion slide 3 to drive the processing unit to move to the initial reference position; setting the horizontal spacing of each movement of the Z-axis motion slide 3 on the X-axis motion slide 1; S3, drive the free end of the electric push rod to extend until the grinding head 7 of the pneumatic grinder contacts with the outer template of the hanging basket, and start the pneumatic grinder. During the rust removal operation, the pneumatic grinder first follows the Z-axis motion slide 3 to move from top to bottom along the vertical direction of the bridge to the bottom of the hanging basket template to remove rust from the template in the vertical direction, and then drives the Z-axis motion slide 3 to move on the X-axis motion slide 1 along the longitudinal direction of the bridge to the next rust removal point according to the set horizontal spacing. The pneumatic grinder follows the Z-axis motion slide from bottom to top along the vertical movement of the bridge to remove rust from the template, and then drives the Z-axis motion slide 3 to move from bottom to top along the longitudinal direction of the bridge to the next rust removal point again, and removes rust from top to bottom again. After multiple cycles of operation, the rust removal operation of the inner side wall 4 of the outer template of the hanging basket is completed. During the rust removal process, the purge gun 8 is always in working condition, which is used to purge the rust residue on the template after grinding and rust removal to avoid the rust residue affecting the rust removal effect; S4. After the rust removal operation is completed, the pneumatic grinder and the purge gun are turned off, and the free end of the electric push rod is driven to be retracted; the Z-axis motion slide 3 is driven back to the initial reference position, and according to the working path of the rust removal operation, the high-pressure water gun 9 is started to wash the concrete residue or residual rust residue on the outer template of the hanging basket to completely remove the impurities remaining on the template. The high-pressure water gun 9 is supplied with water through the high-pressure water pump station; S5. After the flushing operation is completed, the high-pressure water gun 9 is turned off, and step S4 is repeated. The release agent is sprayed on the inner side wall of the outer template of the hanging basket through the spray gun 10. The release agent is supplied through the external release agent pump station. At this point, the cleaning operation of the inner side wall 4 of the outer template of the hanging basket is completed; S6, drive the Z-axis motion slide 3 back to the initial reference position again, and continue to move upward until the processing unit is located above the top surface of the outer template of the hanging basket, and use this as the initial working position, drive the free end of the electric push rod to extend until the grinding head 7 of the pneumatic grinder contacts with the top surface 5 of the outer template of the hanging basket, and drive the pneumatic grinder to perform rust removal. When removing rust, first drive the X-axis motion slide 1 to move on the Y-axis motion slide 2, and drive the Z-axis motion slide 3 to move along the horizontal direction of the bridge toward the outer side of the template, so as to realize the rust removal of the top surface of the outer template of the hanging basket along the horizontal direction of the bridge, and then according to the moving distance set in step S2, drive the Z-axis motion slide 3 to move to the next point along the longitudinal direction of the bridge, and move along the horizontal direction of the bridge toward the inner side of the template while performing rust removal. After multiple cycles of operation, the rust removal of the slope of the top surface of the outer template of the hanging basket is completed; S7, after the rust removal is completed, turn off the pneumatic grinder and the purge gun, drive the free end of the electric push rod to retract; drive the Z-axis motion slide 3 back to the initial working position, and complete the flushing operation of the top surface 5 of the outer template of the hanging basket according to the working path of step S6; S8, repeat step S7, spray the release agent onto the top surface 5 of the hanging basket outer template through the spray gun 10, and thus complete the cleaning operation of the hanging basket outer template; during the cleaning operation, two sets of processing devices are used to synchronously clean the hanging basket outer templates on both sides.

[0017] In this technical solution, the three-axis motion slide and the processing unit cooperate with each other to achieve the cleaning operation of the outer formwork of the hanging basket, thereby ensuring the appearance quality of the subsequent bridge segment construction and replacing manual operations, which helps to promote the advancement of construction technology, thereby reducing the construction period, improving construction efficiency, and reducing labor costs and equipment usage costs.

[0018] In another technical solution, an annular plate 11 is installed on the outer periphery of the pneumatic grinder housing, and a plurality of magnetic devices 12 are installed on the annular plate 11. The magnetic devices 12 and the grinding head 7 of the pneumatic grinder are located in the same plane; When removing rust, the free end of the electric push rod is driven to extend until the magnetic device 12 is adsorbed on the outer template of the hanging basket, and then the pneumatic grinder is started to work.

[0019] In the technical solution described above, a magnetic device 12 is installed on the outer periphery of the pneumatic grinder housing. During rust removal, the magnetic device 12 fits well on the outer template of the hanging basket, which can ensure that the grinding head 7 fits well with the template and ensures the rust removal effect.

[0020] In another technical solution, a pressure sensor 13 is installed on any magnetic suction device 12, which is used to monitor the clamping force between the magnetic suction device 12 and the outer template of the hanging basket. The pressure sensor 13 and the electric push rod are both connected to the electric control cabinet; during rust removal, when the electric control cabinet detects that the clamping force obtained by the pressure sensor 13 has a numerical change, the electric push rod is controlled to stop moving.

[0021] In the above technical solution, since the end face of the magnetic suction device 12 and the end face of the grinding head 7 are in the same plane, a pressure sensor 13 is installed on the magnetic suction device 12, and its pressure value is monitored by the control cabinet. When the electric control cabinet detects that the clamping force obtained by the pressure sensor 13 has a numerical change, it means that the magnetic suction device 12 has been adsorbed on the outer template of the hanging basket, that is, the grinding head 7 is in contact with the side wall of the outer template of the hanging basket, and the electric push rod does not need to continue to extend. The control cabinet immediately controls the electric push rod to stop moving, which is convenient for the control operation of the electric push rod.

[0022] In another technical solution, the magnetic device 12 is connected to the electric control cabinet, and a pressure target value is set in the electric control cabinet. The electric control cabinet monitors the pressure value obtained by the pressure sensor 13 and compares it with the target value. If it is less than the target value, the current of the magnetic device 12 is controlled to increase; if it is greater than the target value, the current of the magnetic device 12 is controlled to decrease.

[0023] In the present technical solution, the pressure value obtained by the pressure sensor 13 monitored by the electric control cabinet is compared with the target value, so as to adjust the current of the magnetic suction device 12 in real time to adjust the magnetic force, so that the magnetic suction device 12 maintains appropriate force to adsorb on the template surface, ensuring the rust removal effect while the grinding head 7 can move smoothly in accordance with the template.

[0024] In another technical solution, a distance sensor is installed at the bottom end of the Z-axis motion slide 3, which is used to monitor the distance between the Z-axis motion slide 3 and the outer template of the hanging basket. The distance sensor is connected to the electric control cabinet. When the Z-axis motion slide 3 moves to the top and bottom ends of the inner wall 4 of the hanging basket outer template, as well as the two sides of the top surface of the hanging basket outer template, the electric control cabinet records the distance value obtained by the distance sensor. After the cleaning operation is completed, the installation angle of the hanging basket outer template is adjusted based on the distance value recorded by the electric control cabinet.

[0025] In the present technical solution, after the concrete pouring of the previous bridge segment is completed, the hanging basket moves to the next bridge segment. During the movement, the position of the hanging basket outer template may be offset. To ensure the construction quality, after the hanging basket is moved into place, it is also necessary to measure and adjust the installation angle of the hanging basket template. Therefore, in order to improve the construction efficiency, the electric control cabinet can be used to record the distance value obtained by the distance sensor when the Z-axis motion slide 3 moves to the top and bottom ends of the inner wall 4 of the hanging basket outer template and the positions on both sides of the top surface of the hanging basket outer template during the spraying of the release agent. After the cleaning operation is completed, the hanging basket template is adjusted to the preset installation angle in time by analyzing and calculating the distance value, which eliminates the template measurement step and improves the construction efficiency. The installation angle of the hanging basket template can be adjusted in the following directions: After the construction of the previous bridge segment is completed, a certain position on the Y-axis motion slide 2 is taken as the first calculation point and marked, the X-axis motion slide 1 is moved to the first calculation point, the Z-axis motion slide 3 is driven to move vertically, and the distance value obtained by the distance sensor when the Z-axis motion slide 3 moves to the top and bottom of the hanging basket outer template is recorded as the first standard value; a certain position on the Z-axis motion slide 3 is taken as the second calculation point and marked, the Z-axis motion slide 3 is driven to move vertically to the second calculation point and connect with the X-axis motion slide 1, and the distance value when the Z-axis motion slide 3 moves to the hanging basket outer template is recorded. When the two sides of the top surface are located, the distance value obtained by the distance sensor is recorded as the second standard value, and then the hanging basket is driven forward to the next bridge section for cleaning. During the cleaning process, the electrical control cabinet records the distance value obtained by the distance sensor when the X-axis motion slide 1 moves to the first calculation point and the second calculation point of the Z-axis motion slide 3 is connected to the X-axis motion slide 1. After the cleaning operation is completed, the distance value obtained by the electrical control cabinet is compared with the first standard value and the second standard value respectively, so as to know the corresponding distance deviation value, and thus adjust the offset distance of the template installation accordingly.

[0026] Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation modes, and they can be fully applied to various fields suitable for the present invention. For those familiar with the art, additional modifications can be easily implemented.
