[0037] Track slabs are key prefabricated components in rail transit projects, and their quality directly impacts the overall performance and service life of the project. During track slab production, cleaning the prefabricated channels is a crucial step in ensuring product quality.

[0038] At present, the cleaning process of prefabricated channels of track plates mainly adopts manual operation or single-function mechanical equipment. The production links are scattered and the track plates need to be repeatedly moved. This not only increases the risk of product damage, but also causes technical problems such as process waiting and low equipment utilization.

[0039] In order to solve this technical problem, the present invention proposes a track plate hole cleaning production line.

[0040] See also Figures 1 to 3In one embodiment of the present invention, the track plate 10 is provided with a plurality of prefabricated channels 11. The track plate hole cleaning production line includes an outer frame 100, a transport track 200, a mobile platform 300, a lifting mechanism 400, a hole cleaning mechanism 600 and a plurality of clamping mechanisms 500. The outer frame 100 is provided with a processing section 101; the transport track 200 passes through the outer frame 100 in a horizontal direction, and the portion of the transport track 200 extending out of the outer frame 100 is provided with an initial section 102; the mobile platform 300 can be slidably arranged on the transport track 200, and the track plate 10 is placed on the mobile platform 300. The mobile platform 300 is used to drive the track plate 10 to move along the transport track 200 in the initial section 102 and the processing section 101; the lifting mechanism 400 is arranged in the processing section 101, and the lifting mechanism 400 is arranged below the track plate 10 The lifting mechanism 400 is used to lift or lower the track plate 10 in the processing area 101, so that the track plate 10 is separated from or loaded on the mobile platform 300; a plurality of clamping mechanisms 500 are arranged at intervals along the circumference of the processing area 101, and each clamping mechanism 500 can move between a clamping position or a release position, correspondingly pressing against the outer edge of the track plate 10 loaded on the lifting mechanism 400 to clamp the track plate 10, or removing from the outer edge of the track plate 10 loaded on the lifting mechanism 400 to release the track plate 10; the hole cleaning end of the hole cleaning mechanism 600 is arranged toward the track plate 10, and the input end of the hole cleaning mechanism 600 is connected to an external water source. The hole cleaning mechanism 600 can be slidably suspended on the outer frame 100 along the circumference of the track plate 10, and the hole cleaning mechanism 600 is used to inject water into any prefabricated channel 11 through the hole cleaning end of the hole cleaning mechanism 600.

[0041] It should be noted that the outer frame 100 refers to a structure that forms a closed working space, which can be specifically constructed using a steel structure truss to limit the equipment operation area and ensure operational safety. The transport track 200 refers to a guide track that carries the mobile platform 300, which can specifically be an I-beam track in combination with rollers 320 to achieve horizontal transportation of the track plate 10. The mobile platform 300 refers to a carrier that carries the track plate 10, which can specifically be a flatbed truck with a drive motor, and realizes automatic displacement through a rack and pinion transmission. The lifting mechanism 400 refers to a vertical lifting device, which can specifically be a hydraulic jacking system, and the lifting block 420 is controlled by a synchronous oil cylinder to smoothly lift the track plate 10. The clamping mechanism 500 refers to a circumferential clamping device, which can specifically be a connecting rod mechanism in combination with a pneumatic push rod to achieve multi-point positioning and clamping after the track plate 10 is lifted. The hole cleaning mechanism 600 refers to a high-pressure cleaning device, which can specifically be a multi-degree-of-freedom robotic arm equipped with a rotating nozzle 670, and realize circumferential position adjustment through a slide rail.

[0042] More specifically, after the track plate 10 enters the processing area 101 along the transport track 200 via the mobile platform 300, the lifting mechanism 400 lifts it up to separate it from the mobile platform 300. The circumferentially arranged clamping mechanisms 500 act synchronously, clamping the outer edge of the track plate 10 through a mechanical linkage device to form a stable support. The hole cleaning mechanism 600 suspended on the top of the frame moves along the circular track, and the high-pressure water pump accurately injects water into the prefabricated channels 11 at different positions through the adjustable angle nozzle 670. After cleaning is completed, the clamping mechanism 500 releases the constraint, and the lifting mechanism 400 descends to make the track plate 10 fall back to the mobile platform 300 and be transported to the next process.

[0043] Compared to existing technologies, the track plate 10 requires repeated lifting between transport fixtures and cleaning stations in traditional processes. This solution, however, achieves spatial overlap through integration. Existing equipment often utilizes fixed cleaning nozzles 670, requiring manual adjustment of the track plate 10's orientation when cleaning different holes. This solution utilizes a movable hole-cleaning mechanism 600 to proactively cover all hole positions. Traditional support methods rely on bottom-up support, which can easily cause plate deformation. This solution utilizes a circumferential clamping mechanism 500 to create a three-dimensional constraint, effectively controlling vibration and deflection during the cleaning process.

[0044] In the technical solution provided by the present invention, the automatic positioning, stable fixation and hole cleaning operations of the track plate 10 in the processing area 101 are achieved by integrating the transport track 200, the mobile platform 300, the lifting mechanism 400, the clamping mechanism 500 and the hole cleaning mechanism 600. It has the characteristics of high integration, good positioning accuracy and excellent automation level. It can effectively solve the technical problems existing in traditional processes such as scattered process, inaccurate positioning and insufficient automation, realize the continuous production of the track plate 10 hole cleaning operation, and eliminate the risk of product damage in the intermediate transportation link. The multi-point clamping mechanism 500 can adapt to the positioning of track plates 10 of different specifications, and the adjustable hole cleaning mechanism 600 can adapt to the layout of various channels. The coordinated operation of the lifting mechanism 400 and the mobile platform 300 improves the utilization rate of the processing area 101 and makes the overall production line layout compact, which is suitable for prefabricated component production workshops with limited space.

[0045] Please continue reading Figures 1 to 3In an embodiment of the present invention, the clamping mechanism 500 includes a push-pull structure 510 and a clamping structure 520. The clamping structure 520 and the push-pull structure 510 are arranged at intervals. The bottom ends of the clamping structure 520 and the push-pull structure 510 are hinged to the processing area 101. The output end of the push-pull structure 510 is hinged to the clamping structure 520 and is used to push the clamping structure 520 toward the outer edge of the track plate 10 to a clamping position, or to pull the clamping structure 520 back to a release position in a direction away from the outer edge of the track plate 10, correspondingly making the clamping structure 520 press against the outer edge of the track plate 10 loaded on the lifting mechanism 400 to clamp the track plate 10, or to remove the clamping structure 520 from the outer edge of the track plate 10 loaded on the lifting mechanism 400 to release the track plate 10.

[0046] It should be noted that the push-pull structure 510 refers to a device that realizes linear push-pull action through mechanical transmission, which can be realized by a hydraulic cylinder or an electric push rod, and its function is to provide power to drive the position change of the clamping structure 520. The clamping structure 520 refers to a component used to directly contact and fix the track plate 10, which can be realized by a connecting rod mechanism with a clamping head, and its function is to achieve stable clamping of the track plate 10 through physical contact. Articulation refers to a structural form that connects two components through a rotating shaft, which can be realized by a pin and a bearing, and its function is to allow the component to rotate freely within a certain angle range to adapt to the position change of the track plate 10.

[0047] More specifically, when the track plate 10 is lifted to the processing position by the lifting mechanism 400, the push-pull structure 510 drives the clamping structure 520 to rotate around the bottom hinge point through the telescopic movement of the output end. When the push-pull structure 510 is pushed outward, the top of the clamping structure 520 moves toward the outer edge of the track plate 10 until the clamping head contacts the side wall of the track plate 10 to form a clamping force; when the push-pull structure 510 is pulled back inward, the top of the clamping structure 520 rotates in the opposite direction to separate from the track plate 10. In this process, a secondary lever structure is formed between the push-pull structure 510 and the clamping structure 520 through the middle hinge point, so that the linear motion of the push-pull structure 510 is converted into the rotational motion of the clamping structure 520, thereby realizing the precise positioning and reliable fixation of the track plate 10. Rapid positioning and stable clamping of the track plate 10 during the hole cleaning process are achieved, solving the technical problems of low positioning accuracy and poor adaptability of traditional support methods. The coordinated action of the push-pull structure 510 and the clamping structure 520 can automatically compensate for the position deviation of the track plate 10, ensuring that the track plate 10 is in the processing position during the hole cleaning operation. At the same time, the hinged structure enables the clamping mechanism to adapt to the fixing requirements of track plates 10 of different specifications, significantly improving the versatility and operational reliability of the production line.

[0048] Please continue reading Figure 3 , and see Figure 4In an embodiment of the present invention, the clamping structure 520 includes a hinge seat 521, a connecting plate 522, a hinge block 523 and a clamping head 524. The hinge seat 521 is installed in the processing area 101, the bottom end of the connecting plate 522 is hinged to the hinge seat 521, the hinge block 523 is installed on the side wall of the connecting plate 522, and the clamping head 524 is installed on the top of the connecting plate 522. The push-pull structure 510 is hinged to the hinge block 523. The push-pull structure 510 is used to drive the hinge block 523 to drive the connecting plate 522 and the clamping head 524 to rotate around the hinge seat 521 to a clamping position or a release position, correspondingly making the clamping head 524 press against the outer edge of the track plate 10 loaded on the lifting mechanism 400 to clamp the track plate 10, or, making the clamping head 524 removed from the outer edge of the track plate 10 loaded on the lifting mechanism 400 to release the track plate 10.

[0049] It should be noted that the articulated seat 521 refers to a basic support component fixed to the processing area 101, which can be specifically implemented by a metal base with an axial hole, and is used to provide a stable rotation fulcrum for the connecting plate 522. The connecting plate 522 refers to a rigid rod that transmits push-pull power, which can be specifically implemented by a steel plate welding structure, and its bottom end forms a rotating pair with the articulated seat 521 to transmit rotational motion. The articulated block 523 refers to a transition component connecting the push-pull structure 510 and the connecting plate 522, which can be specifically implemented by a metal block with an articulated hole, and is used to convert the linear motion of the push-pull structure 510 into the rotational motion of the connecting plate 522. The clamping head 524 refers to a clamping component that directly contacts the track plate 10, which can be specifically implemented by a metal pressing block with a rubber buffer layer, and is used to form a flexible pressure on the track plate 10 after rotating into place.

[0050] More specifically, when the push-pull structure 510 exerts a thrust, the hinge block 523 is pushed, driving the connecting plate 522 to rotate clockwise about the hinge seat 521, causing the clamping head 524 mounted on the top of the connecting plate 522 to move toward the outer edge of the track plate 10 until it is clamped. When the push-pull structure 510 exerts a pulling force, the hinge block 523 is pulled, driving the connecting plate 522 to rotate counterclockwise, causing the clamping head 524 to separate from the outer edge of the track plate 10. The hinged connection between the connecting plate 522 and the hinge seat 521 allows the clamping head 524 to move in a circular arc within a plane. The mounting position of the hinge block 523 determines the transmission ratio between the travel of the push-pull structure 510 and the displacement of the clamping head 524. The rubber buffer layer of the clamping head 524 prevents damage to the track plate 10 surface due to rigid contact. Multi-angle adaptive clamping of the track plate 10 during the lifting process is realized, which solves the technical problems of low positioning accuracy and poor product adaptability of traditional support methods; through the cooperation of the split clamping mechanism 500 and the buffer structure, the surface damage of the track plate 10 is avoided while ensuring the clamping stability; by utilizing the transmission of the push-pull structure 510 and the hinge block 523, the response speed and positioning accuracy of the clamping action are improved, the manual adjustment link is reduced, and a reliable positioning reference is provided for subsequent hole cleaning operations.

[0051] Please continue reading Figure 4 In an embodiment of the present invention, the clamping head 524 includes a mounting portion 525 and a clamping portion 526. The mounting portion 525 is mounted on the top of the connecting plate 522, and the clamping portion 526 is protruded from the mounting portion 525 toward the direction close to the track plate 10. The clamping portion 526 is used to press against the outer edge of the track plate 10 to clamp the track plate 10, or to be removed from the outer edge of the track plate 10 to release the track plate 10.

[0052] It should be noted that the mounting portion 525 is a structural member used to secure the clamping head 524 to the top of the connecting plate 522. Specifically, it can be implemented using a metal base with bolt holes. Bolts are used to achieve a removable connection between the clamping head 524 and the connecting plate 522. This feature enables the clamping head 524 to transmit a stable clamping force while facilitating maintenance and replacement.

[0053] The pressing portion 526 is a contact component extending from the mounting portion 525. Specifically, it can be implemented as a metal bump with a curved contact surface, whose protrusion direction matches the curved surface of the outer edge of the track plate 10. This feature maximizes the contact area by geometrically adapting to the contour of the track plate 10 and preventing localized stress concentration.

[0054] More specifically, when the push-pull structure 510 drives the connecting plate 522 to rotate around the hinge seat 521, the mounting portion 525 acts as a rigid support point to push the clamping portion 526 toward the outer edge of the track plate 10. The raised structure of the clamping portion 526 enables it to penetrate into the recessed area at the edge of the track plate 10, such as the slot or ridge structure on the side of the track plate 10, to form multi-point contact. During the release process, the clamping portion 526 moves in the opposite direction of the raised direction and disengages from the contact area with the track plate 10. This achieves a uniform distribution of contact pressure during the clamping process of the track plate 10, effectively preventing the edge of the track plate 10 from cracking due to excessive local stress. The directional raised structure of the clamping portion 526 can adapt to the clamping requirements of track plates 10 of different thicknesses, ensuring clamping stability while improving the versatility of the equipment. The split structure facilitates the individual replacement of worn parts, reducing maintenance costs compared to the integral clamp.

[0055] Please continue reading Figure 4 In an embodiment of the present invention, the hinge block 523 is disposed between the mounting portion 525 and the hinge seat 521 , and the pressing portion 526 is disposed between the hinge block 523 and the mounting portion 525 .

[0056] It should be noted that the hinge block 523 refers to the intermediate transmission component connecting the push-pull structure 510 and the clamping structure 520. Specifically, it can be implemented by a metal block with a hinge hole. It is arranged between the mounting portion 525 and the hinge seat 521 to optimize the force transmission path. The clamping portion 526 refers to the force-applying component that directly contacts the outer edge of the track plate 10. Specifically, it can be implemented by a rubber block with an arc surface structure. It is arranged between the hinge block 523 and the mounting portion 525 to form a compact force application point. The mounting portion 525 refers to the base structure for fixing the clamping portion 526. Specifically, it can be implemented by a steel plate welded frame, which is connected to the top of the connecting plate 522 to form a stable support. The hinge seat 521 refers to the rotation fulcrum at the bottom end of the connecting plate 522. Specifically, it can be implemented by a cast steel part with an axial hole. It is fixedly connected to the processing area 101 to form a reliable support foundation.

[0057] More specifically, when the push-pull structure 510 drives the hinge block 523, the hinge block 523 causes the connecting plate 522 to rotate about the hinge seat 521. At this point, the pressing portion 526 is displaced within the space defined by the hinge block 523 and the mounting portion 525. Because the pressing portion 526 is constrained between the hinge block 523 and the mounting portion 525, its motion trajectory is effectively controlled, ensuring that the pressing portion 526 always contacts the outer edge of the track plate 10 along a predetermined path. The mounting portion 525, serving as a fixed carrier for the pressing portion 526, forms a dual positioning structure with the hinge block 523, allowing the clamping head 524 to maintain a stable posture during operation. This layout places the force application point of the pressing portion 526 closer to the hinge block 523, effectively shortening the torque transmission distance. This effectively addresses the positioning deviation problem caused by the loose structure of the conventional clamping mechanism 500, allowing the pressing portion 526 to align with the outer edge of the track plate 10. The compact layout enhances the overall rigidity of the mechanism and avoids the cumulative errors caused by multiple components connected in series. The optimized force transmission path reduces driving energy consumption, while enabling the clamping mechanism 500 to adapt to the clamping requirements of track plates 10 of different thicknesses.

[0058] In an embodiment of the present invention, a buffer member is sleeved on the outer edge of the pressing portion 526 .

[0059] It should be noted that the buffer member refers to a flexible material layer wrapped around the outer surface of the clamping portion 526, and can be implemented as a rubber sleeve, silicone sleeve, or polyurethane sleeve. It absorbs the impact force generated during the clamping process through elastic deformation. The clamping portion 526 refers to a structural component that protrudes from the mounting portion 525 toward the track plate 10, and can be implemented as a structure with a metal substrate covered with a wear-resistant layer. It is used to directly contact the outer edge of the track plate 10 to apply the clamping force.

[0060] More specifically, when the clamping mechanism 500 is in the clamping position, the pressing portion 526 contacts the outer edge of the track plate 10 through the buffer. The buffer undergoes elastic deformation during the clamping process, which can not only disperse local pressure and prevent the hard clamping portion 526 from directly contacting the surface of the track plate 10 and causing scratches, but also maintain stable clamping contact through elastic restoring force. In the release position, the buffer is synchronously separated from the surface of the track plate 10 along with the clamping portion 526, and its elastic properties can avoid rigid collision with the track plate 10. It effectively solves the problem that the surface of the track plate 10 is easily damaged during the clamping process. The elastic properties of the buffer can automatically compensate for the dimensional tolerance of the track plate 10, improve the adaptability to products of different specifications, and reduce the influence of the vibration of the clamping mechanism on the positioning accuracy.

[0061] Please continue reading Figure 4In an embodiment of the present invention, the push-pull structure 510 includes a push-pull driving member 511 and a connecting seat 512. The connecting seat 512 is installed in the processing area 101. The connecting end of the push-pull driving member 511 is hinged to the connecting seat 512. The free end of the push-pull driving member 511 is hinged to the clamping structure 520. The push-pull driving member 511 is used to drive the clamping structure 520 to rotate to a clamping position or a release position.

[0062] It should be noted that the push-pull drive member 511 refers to a power device that drives the clamping structure 520 to rotate through linear motion. Specifically, it can be implemented by a hydraulic cylinder or an electric push rod. Its function is to provide a stable thrust to control the motion trajectory of the clamping structure 520. The connecting seat 512 refers to a supporting member fixed to the processing area 101. Specifically, it can be implemented by a welded steel plate or a bolted base. Its function is to provide a stable hinge fulcrum for the push-pull drive member 511 to ensure the effective transmission of the driving force. The hinged connection method refers to the rotational connection between components achieved by a pin shaft. Specifically, it can be implemented by an articulated pair with a self-lubricating bearing. Its function is to allow the push-pull drive member 511 to produce angle changes during the driving process to adapt to the arc motion path of the clamping structure 520.

[0063] More specifically, when the push-pull drive member 511 performs telescopic movement, its free end drives the clamping structure 520 to rotate around the hinge axis of the connecting seat 512 through the hinge point. When the driving stroke reaches the set value, the clamping portion 526 at the end of the clamping structure 520 will accurately reach the predetermined position, achieving reliable clamping or complete separation of the outer edge of the track plate 10. This structure forms a repeatable positioning mechanical motion system through a combination of rigid connection and rotational movement, ensuring the consistency of the trajectory of each action. The control of the motion trajectory of the clamping mechanism 500 is achieved, and the adaptability of the equipment to changes in workpiece size is improved while ensuring clamping stability. It effectively solves the problem of clamping failure caused by positioning errors of traditional linear drive mechanisms, and simplifies the position calibration process during equipment debugging.

[0064] Please continue reading Figure 3 , and see Figure 5 In an embodiment of the present invention, the lifting mechanism 400 includes a base 410, a lifting drive member and a lifting block 420. The base 410 is arranged in the processing area 101. A storage space is provided in the base 410. The top of the base 410 is provided with an opening connected to the storage space. The lifting drive member is accommodated in the storage space. The lifting block 420 is slidably arranged on the base 410 along the vertical direction. The top end of the lifting block 420 extends out of the opening, and the bottom end of the lifting block 420 extends into the storage space and is connected to the output end of the lifting drive member. The lifting drive member is used to drive the lifting block 420 to move up and down, so as to drive the track plate 10 in the processing area 101 to be lifted or lowered, so that the track plate 10 is separated from or loaded on the mobile platform 300.

[0065] It should be noted that base 410 refers to the support structure that supports the lifting drive and lifting block 420. It can be implemented as a welded steel frame, with internal space for mounting the lifting drive and limiting its motion trajectory. The lifting drive refers to the actuator that provides vertical power, and can be implemented as a hydraulic cylinder or electric push rod. The output end is connected to the lifting block 420 to achieve power transmission. The lifting block 420 is the supporting component that directly contacts the track plate 10. It can be implemented as a metal block with guide grooves, and the sliding fit ensures the stability of vertical lifting.

[0066] More specifically, when the track plate 10 is transported to the processing area 101 via the mobile platform 300, the lifting drive activates and propels the lifting block 420 vertically upward along the guide structure within the base 410. The top of the lifting block 420 passes through the opening at the top of the base 410 to contact the bottom of the track plate 10, smoothly lifting it to a predetermined height. The track plate 10 is now detached from the mobile platform 300, forming an independently supported state for subsequent fixing and hole cleaning operations. After processing is complete, the lifting drive reverses, driving the lifting block 420 downward, and the track plate 10 returns to the mobile platform 300 for loading. The entire lifting process is controlled by the internal space of the base 410 to maintain motion accuracy, while the opening allows the lifting block 420 to effectively transmit the lifting force. This achieves automatic positioning and separation of the track plate 10 within the processing area 101, resolving the issues of non-adjustable height and low positioning accuracy associated with traditional support methods. The lifting mechanism 400 works in conjunction with the mobile platform 300, eliminating the efficiency losses associated with manual handling and accommodating the processing requirements of track plates 10 of varying specifications. The closed base 410 structure effectively protects the internal driving components, and the guide system ensures a smooth and reliable lifting process, providing a stable working benchmark for subsequent hole cleaning operations.

[0067] Please continue reading Figures 1 to 3 In an embodiment of the present invention, the mobile platform 300 includes a mobile frame 310, a horizontal displacement drive and a roller 320. The track plate 10 is placed on the mobile frame 310. The mobile frame 310 is installed on the transport track 200 through the roller 320. The output end of the horizontal displacement drive is connected to the mobile frame 310. The horizontal displacement drive is used to drive the mobile frame 310 to drive the track plate 10 to move along the transport track 200 in the initial section 102 and the processing section 101.

[0068] It should be noted that the mobile frame 310 refers to the supporting structure that supports the track plate 10, which can be implemented by a steel frame structure. Positioning bumps or limit baffles can be set on its surface to fix the position of the track plate 10. The horizontal displacement drive refers to a device that provides horizontal movement power, which can be implemented by an electric push rod or a hydraulic cylinder. It pushes the mobile frame 310 to move along the track through linear motion. The roller 320 refers to the walking component that enables the sliding of the mobile frame 310. It can be implemented by a steel wheel body with bearings. The wheel rim can be provided with a guide groove to cooperate with the transport track 200 to prevent derailment.

[0069] More specifically, the track plate 10 is placed on the bearing surface of the mobile frame 310, and the initial positioning is achieved by the limiting structure on the frame. The roller 320 group is arranged along the extension direction of the transport track 200, so that the mobile frame 310 has the freedom to slide along the track. The horizontal displacement drive is fixed to the side wall of the mobile frame 310 through a rigid connector. When the drive is started, it pushes the entire mobile frame 310 to move horizontally along the track. In the initial section 102, the mobile frame 310 is in a standby position to facilitate the loading of the track plate 10; after entering the processing section 101, the mobile frame 310 stops moving to allow the track plate 10 to enter the processing station. The roller 320 and the track are clearance-fitted to ensure smooth sliding and avoid excessive shaking.

[0070] In some embodiments, multiple sets of rollers 320 can be installed at the bottom of the mobile frame 310 to distribute the load. For example, a set of rollers 320 can be placed at each of the four corners of the frame. The horizontal displacement drive can utilize a synchronized dual-drive structure, with drive units symmetrically positioned on either side of the mobile frame 310 to ensure balanced movement. The rollers 320 can be coated with a polyurethane coating to reduce operating noise and increase friction to prevent slippage.

The mounting plate 610 extends in the horizontal direction, and the mounting plate 610 is arranged at the top of the rectangular frame. The horizontal moving drive member 620 is installed on the top of the mounting plate 610. The pulley is installed at the bottom of the mounting plate 610 through the vertical central axis. The pulley slides with any horizontal slide rail 110, and the vertical central axis is connected to the output end of the horizontal moving drive member 620; the mounting seat 630 is installed on the top of the mounting plate 610. The mounting seat 630 and the horizontal moving drive member 620 are arranged at intervals in the horizontal direction. The rod 640 is installed on the side of the mounting seat 630 facing the track plate 10, and the horizontal moving drive member 620 is used to drive the vertical central axis to rotate, so that the pulley drives the mounting plate 610 and the mounting seat 630, the vertical rod 640, the shell 650, the hole cleaning drive member 660, the nozzle 670 and the limit seat 680 to move along the circumference of the rectangular frame; the shell 650 extends in the horizontal direction, and the two ends of the shell 650 along the extension direction are respectively the mounting end and the hanging end, and the hanging end faces the track plate. 10 is set, the hole cleaning drive member 660 is installed at the installation end, the nozzle 670 extends in the horizontal direction, the output end of the nozzle 670 forms the hole cleaning end, the limit seat 680 is suspended at the bottom of the hanging end, the nozzle 670 is installed on the limit seat 680, the input end of the hole cleaning drive member 660 is connected with the water source, and the output end of the hole cleaning drive member 660 is connected with the input end of the nozzle 670 through the water supply pipe. The hole cleaning drive member 660 is used to inject the water source into any prefabricated channel 11 through the nozzle 670.

[0072] It should be noted that the horizontal slide rail 110 refers to the guide rail that forms the rectangular frame. Specifically, it can be implemented using an H-shaped steel track to provide a sliding path for the pulley. The pulley refers to the transmission component that rolls along the horizontal slide rail 110. Specifically, it can be implemented using a nylon roller 320 with a bearing, which reduces the movement resistance through rolling friction. The horizontal moving drive 620 refers to the power device that drives the pulley to rotate. Specifically, it can be implemented using a servo motor in conjunction with a reducer, and the movement speed is adjusted by controlling the rotation speed. The mounting plate 610 refers to the platform structure that supports the moving component. Specifically, it can be implemented using a steel plate welded frame to ensure that the structural rigidity meets the load-bearing requirements. The vertical center axis refers to the transmission shaft connecting the pulley and the drive member. Specifically, it can be implemented using a hollow stainless steel shaft, and cables and pipes can be arranged inside. The nozzle 670 refers to a high-pressure water jet device. Specifically, it can be implemented using a tungsten steel nozzle. The limit seat 680 refers to the suspension structure that fixes the nozzle 670. Specifically, it can be implemented using an adjustable universal joint bracket to allow fine-tuning of the spray angle.

[0073] More specifically, the rectangular frame formed by the end-to-end connection of the horizontal slide rail 110 constitutes the mobile track foundation of the hole cleaning mechanism 600. The horizontal moving drive member 620 installed on the top of the mounting plate 610 drives the pulley to roll along the horizontal slide rail 110 by driving the vertical central axis, so that the entire hole cleaning mechanism 600 moves circumferentially along the track plate 10. When the hole cleaning mechanism 600 moves to the target position, the hole cleaning drive member 660 pressurizes the water source and delivers it to the nozzle 670 through the water supply pipe. The high-pressure water flow is injected into the prefabricated channel 11 from the output end of the nozzle 670 to complete the cleaning operation. The limit seat 680 maintains the horizontal extension state of the nozzle 670 through the universal joint structure to ensure that the injection axis coincides with the channel axis. The vertical rod 640 forms a rigid connection with the mounting seat 630 to provide stable support for the shell 650. The sliding fit between the pulley and the horizontal slide rail 110 adopts an adjustable gap to ensure smooth movement and avoid shaking. By combining a rectangular frame and a slide rail to form a closed-loop moving path, and cooperating with a pulley assembly driven by a servo motor, the hole cleaning mechanism 600 can realize continuous and automatic movement along the circumference of the track plate 10, and all prefabricated channels 11 can be covered without interrupting the operation. The adjustable angle limit seat 680 overcomes the defect that the traditional fixed nozzle 670 is difficult to adapt to different aperture positions, and the closed-loop control of the horizontal moving drive 620 significantly improves the positioning accuracy. It achieves full circumferential coverage and precise positioning of the hole cleaning operation, and solves the problem of cleaning blind spots caused by the limited operating range of traditional equipment. The rolling matching structure of the pulley and the slide rail reduces the energy consumption of movement, and the servo drive system ensures that the nozzle 670 is accurately positioned to each prefabricated channel 11. The adjustable nozzle 670 bracket enhances the adaptability of the equipment to different aperture positions and effectively improves the cleaning qualification rate. The closed-loop moving path cooperates with the automated control system to enable the hole cleaning process to seamlessly connect the upper and lower processes to form a continuous production line.
