Description

Technical Field

[0001] This application relates to the field of cleaning devices, and in particular to an integral cover plate cleaning machine for tunnel segment molds. Background Technology

[0002] With the large-scale development of underground space development and the construction of infrastructure such as transportation and energy, shield tunneling technology has also developed rapidly. Tunnel lining concrete segments, as an essential product for shield tunneling, are in increasing demand. The outer arc surface of the segments is shaped by cover plates to ensure the curvature dimensions, which is crucial for guaranteeing the overall quality and stability of the tunnel. Cover plates play a key role in the production of tunnel lining concrete segments; their quality and performance directly affect the forming effect of the segments and the service life of the tunnel. With the continuous advancement of shield tunneling technology, the quality requirements for the segments are becoming increasingly stringent, thus the forming and cleaning of cover plates have received more attention.

[0003] In the production of concrete tunnel lining segments, the cover plates need to be cleaned to ensure the forming quality of the outer arc surface of the segments. Cover plates come in various forms, including two-piece cover plates, integral cover plates, and intermediate cover plates with end plates. For integral cover plates, cleaning was traditionally done manually. After each shift of pouring, the integral cover plate was lowered to a position accessible to workers. Workers would first use a shovel to remove the adhering concrete from the inner surface of the cover plate where it contacts the concrete, then wash it with a high-pressure water gun, and finally apply a release agent to prevent rusting.

[0004] However, manually cleaning the entire cover plate is inefficient due to the limited operating space. Workers need to spend a long time in a relatively small space during the cleaning process, which also poses significant safety hazards. Therefore, this method needs to be improved. Summary of the Invention

[0005] To improve the efficiency of manually cleaning the entire cover plate, this application provides an integral cover plate cleaning machine for tunnel segment molds.

[0006] The integrated cover plate cleaning machine for tunnel segment molds provided in this application adopts the following technical solution: An integrated cover plate cleaning machine for tunnel segment molds is provided for cleaning cover plates. It includes a work frame, a lifting mechanism, a cleaning machine, and a positioning mechanism. The lifting mechanism is located at the top of the work frame and connected to the cover plate, used to drive the cover plate to move up and down. The cleaning machine includes a traveling mechanism and a cleaning mechanism. The traveling mechanism drives the cleaning mechanism to move below the cover plate, and the cleaning mechanism can abut against the cover plate to clean its inner wall. The positioning mechanism is located on the work frame and can be connected to the traveling mechanism to center the cleaning machine relative to the cover plate.

[0007] By adopting the above technical solution, after the tunnel segment is formed to the specified arc size using the cover plate, the lifting mechanism is activated to move the cover plate upwards, removing the tunnel segment. The traveling mechanism then moves the cleaning mechanism to directly beneath the cover plate, at which point the cleaning machine and the cover plate are aligned. Subsequently, the positioning mechanism is activated, bringing it into contact with the traveling mechanism to fix the cleaning machine in place. Next, the lifting mechanism is activated to move the cover plate downwards until its inner wall contacts the cleaning mechanism. The cleaning mechanism then cleans the inner wall of the cover plate, ensuring accurate cleaning. The entire process is highly automated, thus improving the efficiency of cleaning the cover plate.

[0008] Optionally, the walking mechanism includes a support frame and several rollers, the cleaning mechanism is mounted on the support frame, the support frame has a receiving box with a top opening, the receiving box is located below the cleaning mechanism, several rollers are mounted on the bottom of the support frame, and the positioning mechanism can abut against the support frame to restrict the movement of the support frame.

[0009] By employing the above technical solution, the rotation of the rollers moves the support frame, allowing the cleaning mechanism to move under the cover plate for cleaning. During the cleaning process, waste material on the cover plate is removed and falls into a receiving box for storage, preventing waste residue from scattering and affecting the working environment.

[0010] Optionally, the cleaning mechanism includes a mounting frame, a moving component, and a cleaning component. The mounting frame is mounted on the support frame via the moving component, which drives the mounting frame to move along the length of the support frame. The cleaning component is mounted on the moving component and can abut against the inner wall of the cover plate for cleaning the cover plate.

[0011] By adopting the above technical solution, when the support frame moves directly under the cover plate, the moving component is activated, which drives the mounting frame to move the cleaning component along the length of the support frame. This allows the cleaning component to clean along the length of the cover plate, ensuring that the entire inner wall of the cover plate can contact the cleaning component, thus improving the comprehensiveness of cleaning the cover plate and avoiding problems of uneven or incomplete cleaning.

[0012] Optionally, the moving component includes a moving motor, a transmission sprocket, a transmission chain, and several moving wheels. Several connecting rods are rotatably mounted on the mounting frame. The connecting rods are arranged along the width direction of the support frame. The ends of the connecting rods are coaxially fixed with the moving wheels. The moving wheels abut against the top wall of the support frame and can roll and slide on the support frame. The moving motor is mounted on the mounting frame. The transmission sprocket is rotatably connected to the mounting frame. The output end of the moving motor is coaxially fixed with the transmission sprocket and is used to drive the transmission sprocket to rotate. The transmission chain is sleeved on the transmission sprocket and one of the connecting rods. The transmission chain meshes with the transmission sprocket. When the transmission sprocket rotates, it drives the transmission chain to drive the connecting rod to rotate.

[0013] By adopting the above technical solution, the mobile motor is started, which drives the transmission sprocket to rotate, which in turn drives the transmission chain to drive one of the connecting rods to rotate, thereby causing the two mobile wheels connected to the connecting rod to rotate, thus realizing the movement of the mounting frame.

[0014] Optionally, the support frame is provided with a guide assembly, which includes a guide chain and a guide sprocket. The guide chain is arranged along the length of the support frame, the guide sprocket meshes with the guide chain, and the guide sprocket is coaxially fixed with one of the connecting rods.

[0015] By adopting the above technical solution, when the transmission chain drives the two moving wheels on the connecting rod to rotate, causing the mounting frame to move, the guide sprocket connected to the connecting rod rotates synchronously. During this process, the guide sprocket rolls along the guide chain, which can ensure the straightness and stability of the mounting frame's movement and prevent it from deviating.

[0016] Optionally, the cleaning assembly includes a rotating rod and several rotating rods. The rotating rods are arranged along the width direction of the support frame. A rotating motor is provided on the mounting frame. A rotating sprocket is coaxially fixed to the output end of the rotating motor to drive the rotating sprocket to rotate. A rotating chain is sleeved on the rotating sprocket and the rotating rod. The rotation of the rotating sprocket drives the rotating chain to drive the rotating rod to rotate. Several rotating rods are arranged at intervals along the circumference of the rotating rod. The rotating rods are connected to the rotating rod. One end of the rotating rod is slidably connected to the mounting frame. The rotating rod is covered with a brush. The brush can contact the inner wall of the cover plate. The mounting frame is provided with a rotating component for driving the rotating rod to rotate.

[0017] By adopting the above technical solution, when the cover plate moves down to contact the cleaning components, that is, when the brush abuts against the inner wall of the cover plate, the rotating wheels cause the mounting frame to move along the length of the support frame, thereby allowing the brush to slide along the cover plate and clean the entire cover plate. During the translation of the mounting frame, the rotating motor is started, driving the rotating sprocket to rotate. Driven by the rotating chain, the rotating rod rotates, causing several rotating rods to move in a circular motion around the rotating rod as an axis. This causes the brushes on the rotating rods to alternately abut against the inner wall of the cover plate, realizing the moving cleaning of the cover plate by the brushes.

[0018] While the rotating rod is making its circular motion, the rotating component is activated, causing the rotating rod to rotate on its own axis. This causes the brush to rotate simultaneously with its own axis, enabling the brush to clean the cover plate in a rotating manner, thereby improving the cleaning effect. When the brush rotates, the entire ring of brushes on the rotating rod participates in cleaning. Compared to the brush always being in contact with a fixed position on the cover plate, the wear and dirt on the brushes are reduced, thus extending the brush's lifespan.

[0019] Optionally, the rotating assembly includes an internal gear and a plurality of rotating gears. The internal gear is fixed on the mounting bracket and is coaxial with the rotating rod. The plurality of rotating gears correspond one-to-one with the rotating rod and are coaxially sleeved on the corresponding rotating rod. The rotating gears are fixed to the rotating rods and are located inside the internal gear and mesh with the internal gear.

[0020] By adopting the above technical solution, when the rotating motor drives the rotating rod to rotate, the rotating gear rotates under the action of the internal gear, thereby causing the rotating rod to carry the brush to rotate and clean the inner wall of the cover plate.

[0021] Optionally, the rotating rod has a cavity, and a plurality of filter holes are formed through the rotating rod. The filter holes are connected to the cavity. A negative pressure pipe is provided in the cavity. The negative pressure pipe is fixed on the mounting frame. One end of the negative pressure pipe faces the cover plate and the other end faces the support frame. A negative pressure machine is provided in the negative pressure pipe. The negative pressure machine is used to draw gas from the top end of the negative pressure pipe to the bottom end of the negative pressure pipe.

[0022] By adopting the above technical solution, when the mounting bracket moves on the support frame, allowing the brush to contact and clean the cover plate, the negative pressure machine is activated. Gas is drawn from the top to the bottom of the negative pressure pipe, passing through the filter holes into the cavity. This creates suction below the cover plate, facilitating the brush to clean away waste. Fine dust particles enter the negative pressure pipe through the filter holes and are then discharged, effectively acting as a dust collector.

[0023] When the rotating rod drives the brush to the bottom of the negative pressure tube, the air blown out through the filter holes of the negative pressure tube blows off the impurities on the brush, thus cleaning the brush. The cleaner brush then moves back to the top of the negative pressure tube to clean the inner wall of the cover plate, improving the cleaning effect and enabling long-term use of the brush.

[0024] Optionally, the rotating rod is provided with a plurality of cleaning rods, the cleaning rods are arranged along the length of the rotating rod, the cleaning rods are located between adjacent rotating rods, and the cleaning rods are provided with a plurality of insertion holes, into which the brush can be inserted.

[0025] By adopting the above technical solution, when the rotating rod rotates, the internal gear and the rotating gear cause the rotating rod to drive the brush to rotate. During this process, the bristles on the brush can be inserted into the insertion hole and then removed from the insertion hole. At this time, the cleaning rod prevents the waste on the brush from continuing to move with the brush, so that the cleaning rod pushes against the waste in the gap of the brush, thereby cleaning the brush and preventing the impurities on the brush from affecting the cleaning effect of the cover plate.

[0026] Optionally, the cleaning rod is slidably connected to the rotating rod, and the cleaning rod can move along the length of the rotating rod. One end of the cleaning rod is connected to the mounting bracket through a connecting spring. The mounting bracket is provided with a plurality of cams, which are arranged at intervals along the circumference of the rotating rod. The other end of the cleaning rod can abut against the cams to drive the cleaning rod to move.

[0027] By adopting the above technical solution, when the rotating rod rotates, it drives the cleaning rod and the rotating rod to perform synchronous circular motion. When the cleaning rod moves to the cam, the end of the cleaning rod abuts against the cam, increasing the distance from the end of the cleaning rod to the mounting bracket. This causes the cleaning rod to compress the connecting spring and move along the length of the rotating rod, achieving lateral movement of the cleaning rod. The direction of movement of the cleaning rod is perpendicular to the direction of movement of the brush. As the brush passes through the insertion hole, the cleaning rod also pushes against the brush laterally, causing the brush to deform and oscillate, thus enabling the cleaning rod to scrape the brush and achieve a thorough cleaning of the brush. When the cleaning rod passes the cam, the connecting spring returns to its original shape, causing the cleaning rod to reset. The setting of several cams causes the cleaning rod to move back and forth, allowing the cleaning rod to periodically clean the brush.

[0028] In summary, this application includes at least one of the following beneficial effects: 1. When the mounting bracket moves on the support frame, allowing the brush to contact and clean the cover plate, the negative pressure machine is activated. Gas is drawn from the top to the bottom of the negative pressure pipe, passing through the filter holes into the cavity. This creates suction below the cover plate, facilitating the brush's removal of waste. Fine dust enters the negative pressure pipe through the filter holes and is then discharged, effectively acting as a dust collector. When the rotating rod moves the brush to the bottom of the negative pressure pipe, the gas blown out through the filter holes blows impurities off the brush, cleaning it. The cleaner brush then moves back to the top of the negative pressure pipe to clean the inner wall of the cover plate, improving cleaning efficiency and extending the brush's lifespan. 2. When the rotating rod rotates, it drives the cleaning rod and the rotating rod to perform synchronous circular motion. When the cleaning rod moves to the cam, the end of the cleaning rod abuts against the cam, increasing the distance between the end of the cleaning rod and the mounting bracket. This causes the cleaning rod to compress the connecting spring and move laterally along the length of the rotating rod. The direction of movement of the cleaning rod is perpendicular to the direction of movement of the brush. As the brush passes through the insertion hole, the cleaning rod also pushes against the brush laterally, causing the brush to deform and oscillate, thus enabling the cleaning rod to scrape the brush thoroughly. When the cleaning rod passes the cam, the connecting spring returns to its original shape, causing the cleaning rod to reset. The multiple cams allow the cleaning rod to move back and forth, enabling it to periodically clean the brush. Attached Figure Description

Detailed Implementation

[0031] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0032] This application discloses an integrated cover plate cleaning machine for tunnel segment molds. (Refer to...) Figure 1 and Figure 2 The integrated cover plate cleaning machine for tunnel segment molds includes a working frame 10, a lifting mechanism 20, a cleaning machine 40, and a positioning mechanism 30. The lifting mechanism 20 is located on top of the working frame 10 and connected to the cover plate. Specifically, the lifting mechanism 20 can be two hydraulic lifting devices. The output end of the hydraulic press is connected to the cover plate through a hook, which can drive the cover plate to move up and down. The cleaning machine 40 includes a traveling mechanism 41 and a cleaning machine 40 structure. The traveling mechanism 41 can drive the cleaning machine 40 structure to move below the cover plate, and the cleaning machine 40 structure can abut against the cover plate to clean the inner wall of the cover plate. The positioning mechanism 30 is located on the working frame 10 and can be connected to the traveling mechanism 41 to center the cleaning machine 40 and the cover plate. The automated operation of the whole process reduces manual intervention, achieves a high degree of automation, and improves the efficiency and accuracy of cleaning the cover plate.

[0033] Reference Figure 1 and Figure 2 The walking mechanism 41 includes a support frame 411 and several rollers 412. The cleaning machine 40 is mounted on the support frame 411. The support frame 411 is provided with a receiving box 413 with an open top. The receiving box 413 is located below the cleaning machine 40. Several rollers 412 are located at the bottom of the support frame 411. The positioning mechanism 30 can abut against the support frame 411 to restrict the movement of the support frame 411.

[0034] Reference Figure 1 and Figure 2Specifically, the positioning mechanism 30 includes a pair of hydraulic cylinders and a metal hook. The hydraulic cylinders are bolted to the work frame 10, and the metal hook is rotatably connected to the output end of the hydraulic cylinders via a rotating component. When the support frame 411 moves directly under the cover plate, the support frame 411 is located between the two hydraulic cylinders. At this time, the two hydraulic cylinders extend simultaneously and use the rotating component to adjust the angle of the metal hook, so that the metal hook can move into the support frame 411 and hook the support frame 411, thereby restricting the displacement of the support frame 411.

[0035] Reference Figure 2 and Figure 3 The cleaning machine 40 includes a mounting frame 50, a moving component 60, and a cleaning component 70. The mounting frame 50 is mounted on a support frame 411 via the moving component 60, which drives the mounting frame 50 to move along the length of the support frame 411. The cleaning component 70 is mounted on the moving component 60 and can abut against the inner wall of the cover plate for cleaning. The mounting frame 50 typically adopts a frame structure to reduce its weight while ensuring sufficient strength. The moving component 60 allows the cleaning component 70 to thoroughly clean the inner wall of the cover plate.

[0036] Reference Figure 2 and Figure 3 The moving component 60 includes a moving motor 61, a transmission sprocket 62, a transmission chain 63, and several moving wheels 64. Several connecting rods 641 rotatably rotate on the mounting frame 50, arranged along the width of the support frame 411. Each end of the connecting rod 641 is coaxially fixed with a moving wheel 64, which abuts against the top wall of the support frame 411 and can roll and slide on the support frame 411. The moving motor 61 is bolted to the mounting frame 50. The transmission sprocket 62 is rotatably connected to the mounting frame 50, and the output end of the moving motor 61 is coaxially fixed with the transmission sprocket 62 to drive the transmission sprocket 62 to rotate. The transmission chain 63 is sleeved on the transmission sprocket 62 and one of the connecting rods 641, meshing with the transmission sprocket 62. When the transmission sprocket 62 rotates, it drives the transmission chain 63 to rotate the connecting rod 641. The moving motor 61 can be a servo motor, capable of precisely controlling speed and direction. The drive sprocket 62 and drive chain 63 must fit tightly to ensure effective power transmission. The surface of the movable wheel 64 must have a certain amount of friction to ensure stable rolling on the support frame 411.

[0037] Reference Figure 2 and Figure 3The support frame 411 is equipped with a guide assembly 80, which includes a guide chain 81 and a guide sprocket 82. The guide chain 81 is arranged along the length of the support frame 411, and the guide sprocket 82 meshes with the guide chain 81. The guide sprocket 82 is coaxially fixed with one of the connecting rods 641. A transmission chain 63 is also sleeved on the connecting rod 641. The function of the guide assembly 80 is to ensure the straightness and stability of the movement of the mounting frame 50 and to prevent it from deviating.

[0038] Reference Figure 3 and Figure 4 The cleaning assembly 70 includes a rotating rod 71 and several rotating rods 72. The rotating rod 71 is arranged along the width direction of the support frame 411. A rotating sprocket 74 is rotatably connected to the mounting frame 50. A rotating motor 73 is provided on the mounting frame 50. The output end of the rotating motor 73 is coaxially fixed with the rotating sprocket 74 and is used to drive the rotating sprocket 74 to rotate. A rotating chain 75 is sleeved on the rotating sprocket 74. The rotating chain 75 is also sleeved on the rotating rod 71. The rotating sprocket 74 and the rotating chain 75 mesh with each other.

[0039] Reference Figure 3 and Figure 5 Several rotating rods 72 are arranged at intervals along the circumference of the rotating rod 71. The rotating rods 72 are connected to the rotating rod 71. One end of the rotating rod 72 is slidably connected to the mounting frame 50. The rotating rod 72 is wrapped with a brush 721. The brush 721 can contact the inner wall of the cover plate. The mounting frame 50 is provided with a rotating component 90 for driving the rotating rod 72 to rotate.

[0040] When the cover plate moves down to contact the cleaning assembly 70, that is, when the brush 721 abuts against the inner wall of the cover plate, the moving wheel 64 rotates, causing the mounting frame 50 to move along the length of the support frame 411, so that the brush 721 slides along the cover plate to clean the entire cover plate. During the translation of the mounting frame 50, the rotating motor 73 is started, driving the rotating sprocket 74 to rotate. Driven by the rotating chain 75, the rotating rod 71 rotates, causing several rotating rods 72 to make circular motion around the rotating rod 71 as the axis. This causes the brushes 721 on the rotating rods 72 to alternately abut against the inner wall of the cover plate, realizing the moving cleaning of the cover plate by the brushes 721.

[0041] While the rotating rod 72 is in circular motion, the rotating component 90 is activated, causing the rotating rod 72 to rotate. This causes the brush 721 to rotate simultaneously with its own rotation, enabling the brush 721 to perform rotational cleaning of the cover plate, thereby improving the cleaning effect. When the brush 721 rotates, the entire circle of brushes 721 on the rotating rod 72 participates in cleaning. Compared to when the brush 721 is always in contact with a fixed position on the cover plate, the wear and dirt on the brush 721 are reduced, thus extending the service life of the brush 721.

[0042] Reference Figure 4 and Figure 5 The rotating assembly 90 includes an internal gear 91 and several rotating gears 92. The internal gear 91 is fixed on the mounting bracket 50 and is coaxial with the rotating rod 71. Each rotating gear 92 corresponds to one of the rotating rods 72 and is coaxially sleeved on its corresponding rotating rod 72. The rotating gears 92 are fixed to the rotating rods 72 and are located inside the internal gear 91, meshing with it. When the rotating motor 73 drives the rotating rod 71 to rotate, the rotating gears 92 rotate under the action of the internal gear 91, causing the rotating rod 72 to carry the brush 721 to rotate and clean the inner wall of the cover plate, improving the cleaning effect.

[0043] Reference Figure 2 and Figure 6 To achieve self-cleaning of the brush 721, a cavity 711 is provided in the rotating rod 71, and several filter holes 712 are opened through the rotating rod 71. The filter holes 712 are connected to the cavity 711. A negative pressure pipe 110 is provided in the cavity 711. The negative pressure pipe 110 is fixed on the mounting bracket 50. One end of the negative pressure pipe 110 faces the cover plate, and the other end faces the support bracket 411. A negative pressure machine is provided in the negative pressure pipe 110. The negative pressure machine is used to draw gas from the top end of the negative pressure pipe 110 to the bottom end of the negative pressure pipe 110.

[0044] When the mounting bracket 50 moves on the support bracket 411, causing the brush 721 to contact and clean the cover plate, the negative pressure machine is activated. Gas is drawn from the top to the bottom of the negative pressure pipe 110, meaning the gas passes through the filter hole 712 into the cavity 711, creating suction below the cover plate. This facilitates the brush 721 cleaning away waste. Fine dust particles enter the negative pressure pipe 110 through the filter hole 712 and are then discharged from the negative pressure pipe 110, effectively acting as a dust collector.

[0045] When the rotating rod 71 drives the brush 721 to the bottom of the negative pressure pipe 110, the air blown out of the negative pressure pipe 110 through the filter hole 712 blows off the impurities on the brush 721, thus cleaning the brush 721. Subsequently, the relatively clean brush 721 moves back to the top of the negative pressure pipe 110 to clean the inner wall of the cover plate, improving the cleaning effect and enabling the brush 721 to be used for a long time.

[0046] Reference Figure 7 and Figure 8The rotating rod 71 is equipped with several cleaning rods 120, which are arranged along the length of the rotating rod 71 and located between adjacent rotating rods 72. Each cleaning rod 120 has several insertion holes 121 into which a brush 721 can be inserted. When the rotating rod 71 rotates, the internal gear 91 and the rotating gear 92 cause the rotating rod 72 to rotate, allowing the brush 721 to rotate. During this process, the bristles on the brush 721 can be inserted into and then removed from the insertion holes 121. At this time, the cleaning rods 120 prevent the waste residue on the brush 721 from continuing to move with it, thus pushing the waste residue in the gaps between the brushes 721 and cleaning the brush 721. This prevents impurities on the brush 721 from affecting the cleaning effect of the cover plate.

[0047] Reference Figure 5 and Figure 8 To further improve the cleaning efficiency of the cleaning rod 120 on the brush 721, the cleaning rod 120 is slidably connected to the rotating rod 71. The cleaning rod 120 can move along the length of the rotating rod 71. One end of the cleaning rod 120 is connected to the mounting bracket 50 through a connecting spring 122. Several cams 51 are fixed on the mounting bracket 50. The cams 51 are arranged at intervals along the circumference of the rotating rod 71. The other end of the cleaning rod 120 can abut against the cams 51 to drive the cleaning rod 120 to move.

[0048] When the rotating rod 71 rotates, it drives the cleaning rod 120 and the rotating rod 72 to perform synchronous circular motion. When the cleaning rod 120 moves to the cam 51, the end of the cleaning rod 120 abuts against the cam 51, increasing the distance between the end of the cleaning rod 120 and the mounting bracket 50. This causes the cleaning rod 120 to compress the connecting spring 122 and move along the length of the rotating rod 71, achieving lateral movement of the cleaning rod 120. The direction of movement of the cleaning rod 120 is perpendicular to the direction of movement of the brush 721. As the brush 721 passes through the insertion hole 121, the cleaning rod 120 also pushes against the brush 721 laterally, causing the brush 721 to deform and oscillate. This allows the cleaning rod 120 to scrape the brush 721, achieving a thorough cleaning of the brush 721. When the cleaning rod 120 passes the cam 51, the connecting spring 122 returns to its original shape, causing the cleaning rod 120 to reset. The arrangement of several cams 51 causes the cleaning rod 120 to move back and forth, thereby enabling the cleaning rod 120 to periodically clean the brush 721.

[0049] Reference Figure 2 and Figure 6Two scrapers are welded to the mounting frame 50. The scrapers are arranged along the length of the rotating rod 71. The brush 721 is located between the two scrapers. When the traveling mechanism 41 is started, it drives the mounting frame 50 to move along the length of the cover plate. The scrapers slide against the inner arc surface of the cover plate to remove the concrete attached to the surface. This process is repeated twice.

[0050] Reference Figure 2 and Figure 6 The mounting frame 50 is also equipped with multiple high-pressure water guns, which are distributed on both sides of the rotating rod 71 and located between the two scrapers. The multiple high-pressure water guns are arranged at intervals along the length of the rotating rod 71, and the outlets of the high-pressure water guns face the cover plate. When the rotating rod 71 rotates, the high-pressure water guns are turned on at the same time, so that water is sprayed while the brush 721 cleans the cover plate. During this process, the mounting frame 50 moves along the support frame 411 to achieve simultaneous spraying and brushing, repeating back and forth twice.

[0051] Reference Figure 2 and Figure 6 The mounting frame 50 is also equipped with a compressed air gun. After brushing, the compressed air is turned on to blow away the surface residue (mud and water), repeating this process twice. The mud and water will fall into the receiving box 413 for storage and eventually be discharged through the drain at the bottom of the receiving box 413. A mold release agent spray gun is also installed on the mounting frame 50. After cleaning, the mold release agent spray gun is turned on to evenly coat the inside of the cover plate with mold release agent, thus completing the process.

[0052] The implementation principle of the shield tunnel segment mold integral cover plate cleaning machine according to this application embodiment is as follows: After the tunnel segment is formed into the specified arc size using the cover plate, the electric lifting device is activated, and the motor drives the transmission chain 63 to move the cover plate up and remove the tunnel segment. Then, using the rollers 412 of the traveling mechanism 41, and supported by the support frame 411, the cleaning machine 40 is moved to directly below the cover plate, at which point the cleaning machine 40 and the center position of the cover plate are aligned. Next, the positioning mechanism 30 is activated to abut against the support frame 411, fixing the cleaning machine 40 so that it cannot move. Subsequently, the electric lifting device is activated again to move the cover plate down until the inner wall of the cover plate contacts the brush 721 of the cleaning machine 40.

[0053] The moving motor 61 is started, driving the connecting rod 641 to rotate via the transmission sprocket 62 and transmission chain 63. This causes the moving wheel 64 to roll on the support frame 411, thereby driving the mounting frame 50 to move along the length of the support frame 411. Simultaneously, the guide assembly 80 ensures the straightness and stability of the mounting frame 50's movement. The rotating motor 73 drives the rotating rod 71 to rotate, causing several rotating rods 72 to move in a circular motion around the rotating rod 71 as an axis. The rotating assembly 90 causes the rotating rods 72 to rotate, enabling the brush 721 to move and rotate to clean the cover plate. The negative pressure machine is started, generating suction to facilitate the brush 721 in cleaning waste residue, while simultaneously vacuuming and cleaning the brush 721. During the rotation of the rotating rod 71, the cleaning rod 120, under the cooperation of the cam 51 and connecting spring 122, periodically cleans the brush 721, ensuring the cleaning effect of the brush 721. The entire process is highly automated, which improves the efficiency and accuracy of cleaning the cover, reduces the intensity of manual labor and safety hazards, and reduces the damage to the equipment caused by waste residue and wastewater.

[0054] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
