Description

Technical Field

[0001] This invention relates to the field of prestressed pipe pile production technology, and in particular to an automated pipe mold cleaning system. Background Technology

[0002] Typically, the mold used to produce prestressed concrete pipe piles consists of an upper mold and a lower mold. During production, grout is injected into the lower mold, the mold is closed, and then the prestressed concrete pipe pile is obtained through a series of processes including tensioning, centrifugation, steam curing, and demolding. After the entire process is completed, the upper and lower molds need to be cleaned to ensure the quality of the prestressed concrete pipe piles in the next production run.

[0003] Currently, there are two main methods for cleaning pipe molds: 1. Manual cleaning: Manually cleaning the pipe mold using a brush. However, this method has low automation, is time-consuming and labor-intensive, and has low cleaning efficiency. 2. Automated cleaning equipment: The cleaning equipment consists of a frame, a brush holder that can be raised and lowered on the frame, a brush plate assembly mounted on the brush holder, and a brush plate drive mechanism mounted on the brush holder. The brush plate drive mechanism drives the brush plate assembly to rotate and clean the pipe mold; for example, a pipe mold cleaning machine disclosed in Chinese Invention Patent Application No. 201610112765.3. However, existing cleaning equipment has the following drawbacks: 1. One cleaning device can only clean a single span of the tube mold, but there are several production lines in the workshop, which means that each production line needs to be equipped with a cleaning device, greatly increasing the equipment cost; 2. Existing cleaning equipment is mainly used to clean the inner wall surface of the tube mold, and cannot effectively clean the tongue and groove surfaces and sealing grooves of the tube mold edges; 3. The tube mold being cleaned may be tilted in the left-right direction (i.e., horizontal radial direction) and the up-down direction (i.e., vertical diameter direction), and the brush plate assembly in the existing cleaning equipment cannot adapt to the tilt of the tube mold and cannot fit the tube mold well, resulting in poor cleaning effect. Summary of the Invention

[0004] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide an automated tube mold cleaning system that can clean tube molds across multiple production lines.

[0005] To achieve the above objectives, the present invention provides an automated tube mold cleaning system for cleaning tube molds on several production lines, wherein the production lines are arranged side by side along the horizontal radial direction of the tube molds. The automated tube mold cleaning system includes a tube mold carrying device and a tube mold cleaning device installed on each production line.

[0006] The tube mold supporting device is used to support the tube mold;

[0007] The tube mold cleaning equipment includes a cleaning support frame, an X-axis truss fixed to the cleaning support frame and extending horizontally along the parallel direction of several production lines, a Z-axis truss that can be moved left and right along the extension direction of the X-axis truss and is installed on the X-axis truss, and a tube mold cleaning mechanism that can be lifted and lowered and installed on the Z-axis truss. The tube mold cleaning mechanism includes a cleaning frame, a cleaning drive source installed on the cleaning frame, a cleaning transmission assembly, and a cleaning component that can be moved and installed on the cleaning frame. The cleaning drive source is connected to the cleaning component through the cleaning transmission assembly, and the cleaning component is used to contact and cooperate with the tube mold.

[0008] Of the tube mold bearing device and the cleaning support frame, at least one can translate back and forth along the axial direction of the tube mold.

[0009] The preferred embodiment of the above technical solution is as follows: the pipe mold bearing device is a transfer flatcar, the transfer flatcar can move back and forth along the axial direction of the pipe mold, and the cleaning support frame is fixedly installed; two positioning columns are fixed on the top surface of the transfer flatcar, and the two positioning columns are arranged side by side along the horizontal radial direction of the pipe mold.

[0010] The preferred embodiment of the above technical solution is as follows: the cleaning support frame includes an array of support components spaced apart on the left and right sides along several production lines, and a cleaning channel formed between two adjacent sets of support components. The support components are fixedly installed, and the cleaning channel allows the transfer flatcar and the tube mold on the transfer flatcar to pass through. The X-axis truss is fixed to the top of the array of support components.

[0011] The preferred embodiment of the above technical solution is as follows: there are two Z-axis trusses, and each Z-axis truss is equipped with a tube mold cleaning mechanism. The two Z-axis trusses and the tube mold cleaning mechanism are arranged side by side along the horizontal radial direction of the tube mold.

[0012] In the tube mold cleaning mechanism, the cleaning component is a cleaning scraper that reciprocates back and forth along the tube mold axis. The cleaning scraper includes a scraper body, a first scraper blade located at the bottom of the scraper body, a scraper protrusion extending downward from the bottom of the scraper body, and a second scraper blade located at the bottom of the scraper protrusion. The first scraper blade can contact and cooperate with the tongue and groove surface of the tube mold edge, the scraper protrusion can be placed in the sealing groove of the tube mold edge, and the second scraper blade can contact and cooperate with the bottom of the sealing groove.

[0013] The preferred embodiment of the above technical solution is as follows: the tube mold cleaning device further includes an X-axis drive mechanism connected between the X-axis truss and the Z-axis truss. The X-axis drive mechanism includes an X-axis drive motor fixed to the Z-axis truss, a first transmission gear driven to rotate by the X-axis drive motor, and a first transmission rack fixed to the X-axis truss and parallel to the X-axis truss. The first transmission gear meshes with the first transmission rack.

[0014] The preferred embodiment of the above technical solution is as follows: the pipe mold cleaning equipment further includes a Z-axis drive mechanism connected between the Z-axis truss and the pipe mold cleaning mechanism. The Z-axis drive mechanism includes a Z-axis drive motor fixed to the Z-axis truss, a second transmission gear driven to rotate by the Z-axis drive motor, and a second transmission rack extending vertically. The second transmission gear meshes with the second transmission rack. The pipe mold cleaning mechanism further includes a mounting base. The second transmission rack is fixedly connected to the mounting base. The cleaning frame is mounted on the mounting base.

[0015] The preferred embodiment of the above technical solution is as follows: the pipe mold cleaning mechanism further includes a floating connecting block, a vertical floating component and a horizontal floating component. The floating connecting block is installed on the mounting base so as to move up and down through the vertical floating component. The cleaning frame is installed on the floating connecting block so as to move left and right along the horizontal radial direction of the pipe mold through the horizontal floating component.

[0016] The vertical floating assembly includes a first guide shaft that is movably supported in the mounting base and a first spring that extends vertically. The lower end of the first guide shaft is fixed in the floating connecting block, and the first spring abuts between the bottom of the mounting base and the top of the floating connecting block.

[0017] The lateral floating assembly includes a second guide shaft that is movably supported in the floating connecting block and a second spring that extends left and right and is located on the left and right sides of the floating connecting block. The second guide shaft is fixed in the cleaning frame and the second spring abuts against the floating connecting block and the cleaning frame.

[0019] The preferred embodiment of the above technical solution is as follows: the automated pipe mold cleaning system further includes a first detection sensor and a second detection sensor, both of which are fixed to the cleaning support frame. The first detection sensor is used to detect the head end of the pipe mold, and the second detection sensor is used to detect the tail end of the pipe mold.

[0020] As described above, the automated pipe mold cleaning system of the present invention has the following beneficial effects:

[0021] In this application, by moving the Z-axis truss along the X-axis truss, the Z-axis truss can drive the mold cleaning mechanism to move back and forth between several production lines, thereby moving the mold cleaning mechanism directly above the mold-bearing equipment on the target production line. This allows for multi-span cleaning of molds on multiple production lines. Subsequently, the mold cleaning mechanism descends relative to the Z-axis truss to a set position, and through the relative forward and backward movement of the mold-bearing equipment and the cleaning support frame along the mold axis, the cleaning components complete the automatic cleaning of the molds on the target production line. This application allows for multi-span cleaning of molds on multiple production lines with a single mold cleaning device, resulting in low equipment cost and enabling fully automated, unmanned operation of the mold production line, meeting the development needs of automated production equipment.

[0112] like Figure 1 As shown, this invention provides an automated cleaning system for pipe molds, used in the cleaning process of pipe molds 10 during the production of prestressed concrete pipe piles. Specifically, it is used to clean pipe molds 10 on several production lines, which are prestressed concrete pipe pile production lines. For ease of description, the axial direction of the pipe mold 10 is defined as the front-to-back direction, which is also the length direction of the pipe mold 10. The horizontal radial direction of the pipe mold 10 is defined as the left-to-right direction, and the vertical diameter direction of the pipe mold 10 is defined as the up-down direction. Based on this, Figure 2 In the view shown, the front and back sides of the paper are the front and back directions, respectively; the left and right sides of the paper are the left and right directions, respectively; and the top and bottom sides of the paper are the top and bottom directions, respectively.

[0113] In the production workshop of prestressed concrete pipe piles, such as Figure 1 and Figure 2As shown, several production lines are arranged side-by-side along the horizontal radial direction of the tube mold 10, and the corresponding tube molds 10 on the several production lines are also arranged side-by-side. The automated tube mold cleaning system involved in this application includes a tube mold carrying device 20 and a tube mold cleaning device 30 installed on each production line. The tube mold carrying device 20 is used to carry the tube mold 10 on the corresponding production line. Figures 3 to 5 ,as well as Figure 7 and Figure 8 As shown, the tube mold cleaning equipment 30 includes a cleaning support frame 31, an X-axis truss 32 fixed to the cleaning support frame 31 and extending horizontally along the parallel direction of several production lines, a Z-axis truss 33 movably mounted on the X-axis truss 32 along its extension direction, and a tube mold cleaning mechanism 40 movably mounted on the Z-axis truss 33. The X-axis truss 32 can span multiple production lines in the left-right direction. The tube mold cleaning mechanism 40 includes a cleaning frame 41, a cleaning drive source 42 mounted on the cleaning frame 41, a cleaning transmission assembly, and a cleaning component movably mounted on the cleaning frame 41. The cleaning frame 41 is mounted on the Z-axis truss 33. The cleaning drive source 42 is connected to the cleaning component via the cleaning transmission assembly. The cleaning component is used to contact and engage with the tube mold 10. At least one of the tube mold bearing device 20 and the cleaning support frame 31 can translate back and forth along the axial direction of the tube mold 10.

[0114] In the aforementioned automated tube mold cleaning system, the Z-axis truss 33 moves left and right along the X-axis truss 32, enabling the Z-axis truss 33 to drive the tube mold cleaning mechanism 40 to move back and forth between several production lines. This allows the tube mold cleaning mechanism 40 to move directly above the tube mold carrying equipment 20 and the tube mold 10 on each production line, enabling the tube mold cleaning mechanism 40 to clean the tube molds 10 on multiple production lines and achieve multi-span cleaning. At the start of the cleaning operation, based on the position of the mold 10 to be cleaned, the Z-axis truss 33 moves along the X-axis truss 32 to a set position, driving the mold cleaning mechanism 40 to move directly above the mold support device 20 on the target production line, on which the mold 10 to be cleaned is carried. Then, the mold cleaning mechanism 40 descends relative to the Z-axis truss 33 to a set position, and the mold cleaning mechanism 40 is in a descending state. Subsequently, the mold support device 20 and the cleaning support frame 31 move back and forth relative to each other in the axial direction of the mold 10. During this process, the cleaning component comes into contact with the part of the mold 10 to be cleaned, and the cleaning drive source 42 drives the cleaning component to move through the cleaning transmission assembly, thereby realizing the automatic cleaning of the mold 10 on the target production line. This application achieves automated cleaning of tube molds 10 on multiple production lines by using a single tube mold cleaning device 30 to move left and right between several production lines, raise and lower the tube mold cleaning device 40 relative to the Z-axis truss 33, and move the tube mold carrying equipment 20 and the cleaning support frame 31 back and forth. This allows the device to move from one span to another for cleaning operations, with low equipment cost and fully automated, unmanned operation of the tube mold 10 production line. It can adapt to different specifications of tube molds 10 with different left and right spacing and different vertical heights, thus meeting the development needs of automated production equipment.

[0115] In the aforementioned automated pipe mold cleaning system, the structure for realizing the relative forward and backward movement between the pipe mold carrying device 20 and the cleaning support frame 31 can be as follows: the pipe mold carrying device 20 is fixedly set, while the cleaning support frame 31 can move forward and backward; or, the pipe mold carrying device 20 can move forward and backward, while the cleaning support frame 31 is fixedly set; or, both the pipe mold carrying device 20 and the cleaning support frame 31 can move forward and backward. Figure 1 and Figure 2 In the embodiment shown, the pipe mold carrying device 20 can move back and forth, while the cleaning support frame 31 is fixedly installed. The following description will focus on this embodiment.

[0116] Preferably, such as Figure 1 and Figure 2As shown, the pipe mold supporting device 20 is a transfer flatcar 21, which can move back and forth along the axial direction of the pipe mold 10. Furthermore, a ground rail 110 is fixed on the workshop floor, and the transfer flatcar 21 moves back and forth along the ground rail 110. Two positioning posts 22 are fixed on the top surface of the transfer flatcar 21, arranged side-by-side along the horizontal radial direction of the pipe mold 10, with the cross-section of the positioning posts 22 being an inverted V-shape. Alternatively, in other embodiments, the pipe mold supporting device 20 can also be a chain machine.

[0117] Furthermore, the preferred structure of the cleaning support frame 31 in the pipe mold cleaning device 30 is as follows: Figures 4 to 6 As shown, the cleaning support frame 31 includes an array of support assemblies 311 spaced laterally along several production lines, and a cleaning channel 312 formed between adjacent sets of support assemblies 311. The support assemblies 311 are fixedly installed, and the cleaning channel 312 is through, allowing the transfer flatcar 21 and the tube mold 10 on the transfer flatcar 21 to pass through. The X-axis truss 32 has two sections, front and rear, which are fixed to the top of the front and rear sides of the array of support assemblies 311 respectively. Each set of support assemblies 311 includes two vertically extending columns 313 arranged side by side, a leveling component installed at the lower end of each column 313, and a longitudinal beam 314 welded and fixed between the two columns 313. A crossbeam 315 is welded and fixed between the columns 313 of two adjacent sets of support assemblies 311 to ensure the structural strength of the cleaning support frame 31. The leveling assembly includes a leveling base plate 316 welded and fixed to the lower end of the column 313, a fixed base plate 317 fixed by anchor bolts, leveling bolts 318 connected in the leveling base plate 316 and the fixed base plate 317, and two leveling nuts 319 threadedly connected to the leveling bolts 318. The two leveling nuts 319 abut against the upper and lower sides of the leveling base plate 316.

[0118] Furthermore, such as Figure 18 As shown, in this application, the parts of the pipe mold 10 to be cleaned are the tongue and groove surface 11 and the sealing groove 12 of the mold edge. Based on this, as Figure 2 and Figure 5 As shown, there are two Z-axis trusses 33, each equipped with a mold cleaning mechanism 40. The two Z-axis trusses 33 and the mold cleaning mechanism 40 are arranged side by side and symmetrically along the horizontal radial direction of the mold 10. In this way, the two sets of Z-axis trusses 33 and the mold cleaning mechanism 40 can simultaneously clean the grooved surfaces 11 and sealing grooves 12 on both sides of the mold 10, improving cleaning efficiency.

[0119] Furthermore, the structure for realizing the left and right translation of the Z-axis truss 33 relative to the X-axis truss 32 is as follows: Figure 3 and Figure 7As shown, the tube mold cleaning device 30 also includes an X-axis drive mechanism connected between the X-axis truss 32 and each Z-axis truss 33. The X-axis drive mechanism includes a first motor mounting plate 344 fixed to the Z-axis truss 33, an X-axis drive motor 341 fixed to the first motor mounting plate 344, a first transmission gear 342 fixed to the motor shaft of the X-axis drive motor 341, and a first transmission rack 343 fixed to the X-axis truss 32 and parallel to the X-axis truss 32. The first transmission gear 342 meshes with the first transmission rack 343. When the X-axis drive motor 341 operates, it drives the first transmission gear 342 to rotate. Through the meshing of the first transmission gear 342 with the first transmission rack 343, the first transmission gear 342 is driven to move left or right along the first transmission rack 343, thereby driving the X-axis drive motor 341, the Z-axis truss 33, and the tube mold cleaning mechanism 40 to move left or right together. Preferably, the front and rear ends of the Z-axis truss 33 are connected to the two X-axis trusses 32 by left-right extending first linear guide rail assemblies 345, making the left-right movement of the Z-axis truss 33 more stable and accurate. In other embodiments, the transmission structure of the first transmission gear 342 and the first transmission rack 343 can be replaced by a nut screw mechanism.

[0120] Furthermore, the structure for realizing the lifting motion of the tube mold cleaning mechanism 40 relative to the Z-axis truss 33 is as follows: Figure 3 , Figure 7 and Figure 8 As shown, the pipe mold cleaning device 30 also includes a Z-axis drive mechanism connected between the Z-axis truss 33 and the pipe mold cleaning mechanism 40. The Z-axis drive mechanism includes a second motor mounting plate 354 fixed to the Z-axis truss 33, a Z-axis drive motor 351 fixed to the second motor mounting plate 354, a second transmission gear 352 fixed to the motor shaft of the Z-axis drive motor 351, and a second transmission rack 353 extending vertically. The second transmission gear 352 meshes with the second transmission rack 353. The pipe mold cleaning mechanism 40 also includes a mounting base 44. The second transmission rack 353 is fixedly connected to the mounting base 44. The cleaning frame 41 is mounted on the mounting base 44. When the Z-axis drive motor 351 operates, it drives the second transmission gear 352 to rotate. Through the meshing of the second transmission gear 352 and the second transmission rack 353, the second transmission gear 352 is driven to move up or down along the second transmission rack 353, thereby driving the tube mold cleaning mechanism 40 to move up or down as well, realizing the raising or lowering of the tube mold cleaning mechanism 40. Preferably, the second motor mounting plate 354 is connected to the mounting base 44 by a vertically extending second linear guide rail assembly 355, which makes the vertical movement of the mounting base 44 more stable and accurate, improving the lifting stability of the tube mold cleaning mechanism 40. In other embodiments, the transmission structure of the second transmission gear 352 and the second transmission rack 353 can be replaced by a nut screw mechanism.

[0121] Preferably, such as Figure 4 and Figure 7 As shown, the automated tube mold cleaning system also includes a vision camera 80, which is mounted on the Z-axis truss 33 and used to acquire images of the edges of the tube mold 10. The vision camera 80 is a 3D light camera, such as a laser line scan camera, or a 2D light camera. Based on the structure of the left and right sets of Z-axis trusses 33 and the tube mold cleaning mechanism 40, this application configures a vision camera 80 on each Z-axis truss 33. There are also two viewing cameras, left and right, which are preferably fixed below the first motor mounting plate 344 by camera brackets 120. The left and right viewing cameras are used to acquire images of the left and right sides of the tube mold 10 to be cleaned and send them to the control system. The control system identifies the X-axis coordinates of the left and right sides of the tube mold 10 in the left-right direction and the Z-axis coordinates in the up-down direction based on the image information, and then controls the moving distance of the left and right sets of Z-axis trusses 33 in the left-right direction and the lifting height of the tube mold cleaning mechanism 40 in the up-down direction.

[0122] Furthermore, such as Figure 4 and Figure 5 As shown, the automated tube mold cleaning system also includes a first detection sensor 91 and a second detection sensor 92 located on the side of each cleaning channel 312. Both the first and second detection sensors 91 and 92 are fixed to the cleaning support frame 31. The first detection sensor 91 detects the head end of the tube mold 10, and the second detection sensor 92 detects the tail end of the tube mold 10. In this embodiment, the second detection sensor 92 detects the tension plate at the tail end of the tube mold 10. The first and second detection sensors 91 and 92 are used to detect the position of the tube mold 10 in real time: based on feedback from the first detection sensor 91 indicating that the tube mold 10 has entered the tube mold cleaning device 30, the Z-axis drive motor 351 and the cleaning drive source 42 are controlled to begin cleaning, achieving tool advance control; based on feedback from the second detection sensor 92 indicating that the tube mold 10 has left the tube mold cleaning device 30, the Z-axis drive motor 351 is controlled to reverse, and the cleaning drive source 42 is controlled to stop, ending cleaning and achieving tool lifting control. The first and second detection sensors 91 and 92 can be grating sensors, through-beam sensors, or laser rangefinders, etc.

[0123] Furthermore, the pipe mold cleaning mechanism 40 is preferably an adaptive pipe mold cleaning mechanism 40, that is, the cleaning frame 41 can float left and right and up and down. Specifically, as shown in the figure... Figure 9 and Figure 10As shown, the pipe mold cleaning mechanism 40 also includes a floating connecting block 45, a vertical floating component 46, and a horizontal floating component 47. The floating connecting block 45 is mounted on the mounting base 44 and can be moved up and down via the vertical floating component 46. The cleaning frame 41 is mounted on the floating connecting block 45 and can be moved left and right along the horizontal radial direction of the pipe mold 10 via the horizontal floating component 47. During the cleaning process, the floating connecting block 45 can float up and down relative to the mounting base 44 via the vertical floating component 46, and the cleaning frame 41 can float left and right relative to the floating connecting block 45 via the horizontal floating component 47. Under the combined action of the vertical floating component 46 and the horizontal floating component 47, the cleaning frame 41 can float up and down and left and right relative to the mounting base 44. The cleaning component used to clean the pipe mold 10 is installed on the cleaning frame 41, which ultimately enables the cleaning component to float up and down and left and right. This allows the cleaning component to adapt to the tilt of the pipe mold 10 in the left and right directions and the tilt in the up and down directions during the cleaning process. The cleaning component makes reliable contact with the part of the pipe mold 10 to be cleaned, thus reliably ensuring the cleaning effect and greatly improving the quality of cleaning the pipe mold 10.

[0124] Furthermore, the preferred structure of the vertical floating component 46 is as follows: Figure 11 and Figure 12 As shown, the vertical floating assembly 46 includes a first guide shaft 461 and a first spring 462 extending vertically. The first guide shaft 461 is supported vertically in the mounting base 44 by an oil-free bushing. The lower end of the first guide shaft 461 is fixed in the floating connecting block 45. The upper end of the first spring 462 abuts against the bottom of the mounting base 44, and the lower end of the first spring 462 abuts against the top of the floating connecting block 45. Preferably, the first spring 462 is sleeved on the first guide shaft 461. Under the action of the first guide shaft 461 and the first spring 462, the floating connecting block 45 floats vertically, thus realizing the vertical floating of the cleaning frame 41 and the cleaning components. In addition, there are two sets of vertical floating assemblies 46, arranged side by side.

[0125] Furthermore, the preferred structure of the lateral floating component 47 is as follows: Figure 13 and Figure 14As shown, the lateral floating assembly 47 includes a second guide shaft 471 extending left and right and a second spring 472. The second guide shaft 471 is supported in the floating connecting block 45 and can move left and right via an oil-free bushing. Both ends of the second guide shaft 471 are fixed in the cleaning frame 41. The second spring 472 is arranged on both the left and right sides of the floating connecting block 45. The cleaning frame 41 has a frame structure, and the floating connecting block 45 is located inside the cleaning frame 41. The inner end of the second spring 472 abuts against the floating connecting block 45, and the outer end of the second spring 472 abuts against the cleaning frame 41. Under the action of the second guide shaft 471 and the second spring 472, the cleaning frame 41 floats left and right, thus realizing the left and right floating of the cleaning component.

[0126] Preferably, such as Figure 13 and Figure 14 As shown, there are two second guide shafts 471, which are arranged side by side on the front and rear sides of the second spring 472 in the front-rear direction. That is, the second spring 472 is not sleeved on the second guide shaft 471, but is arranged side by side with the second guide shaft 471. The installation structure of the second spring 472 is as follows: the transverse floating assembly 47 also includes a spring fixing sleeve 473 facing the second spring 472 and fixed to the cleaning frame 41. The left and right sides of the floating connecting block 45 are provided with spring positioning holes facing the spring fixing sleeve 473. The inner and outer ends of the second spring 472 are respectively accommodated in the spring positioning holes and the spring fixing sleeve 473.

[0127] like Figure 9 and Figure 10 As shown, the cleaning transmission assembly includes a transmission slider 51 that is reciprocally mounted on the cleaning frame 41 along the length of the tube mold 10, and the cleaning component is a cleaning scraper 43 mounted on the transmission slider 51. Figure 15As shown, the cleaning scraper 43 includes a scraper body 431, a first scraper blade 432 located at the bottom of the scraper body 431, a scraper protrusion 433 protruding downward from the bottom of the scraper body 431, and a second scraper blade 434 located at the bottom of the scraper protrusion 433. The first scraper blade 432 is used to clean the tongue and groove surface 11 of the mold edge of the tube mold 10, and the scraper protrusion 433 and the second scraper blade 434 are used to clean the sealing groove 12 of the mold edge of the tube mold 10. During the cleaning process, the first scraper blade 432 at the bottom of the cleaning scraper 43 abuts against the tongue and groove surface 11 of the mold edge of the tube mold 10, and the two are in contact and engaged. The scraper protrusion 433 at the bottom of the cleaning scraper 43 is located in the sealing groove 12 of the mold edge of the tube mold 10, and the second scraper blade 434 abuts against the bottom surface of the sealing groove 12, and the two are in contact and engaged. As the flatcar moves the tube mold 10, the cleaning drive source 42 actuates, driving the transmission slider 51 and the cleaning scraper 43 to reciprocate back and forth via the cleaning transmission assembly. The first scraper blade 432 at the bottom of the cleaning scraper 43 cleans the tongue and groove surface 11 of the tube mold 10, and the second scraper blade 434 at the bottom of the cleaning scraper 43 cleans the sealing groove 12. Thus, this application effectively cleans the tongue and groove surface 11 and the sealing groove 12 of the tube mold 10 using the first scraper blade 432 and the second scraper blade 434 at the bottom of the cleaning scraper 43, achieving good cleaning effect and high cleaning efficiency.

[0128] Furthermore, such as Figure 9 and Figure 13 As shown, the cleaning drive source 42 is a motor, and the cleaning transmission assembly adopts a crank-connecting rod mechanism. Specifically, the cleaning transmission assembly also includes a transmission crank 52 fixed on the motor shaft of the cleaning drive source 42, a first transmission shaft 53 fixed in the transmission crank 52, a second transmission shaft 54 ​​fixed in the transmission slider 51, a transmission connecting rod 55, and a fisheye connector 56. The motor shaft of the cleaning drive source 42, the first transmission shaft 53, and the second transmission shaft 54 ​​are parallel and extend horizontally. One end of the transmission connecting rod 55 is rotatably engaged with the first transmission shaft 53 through the fisheye connector 56, and the other end of the transmission connecting rod 55 is rotatably engaged with the second transmission shaft 54 ​​through the fisheye connector 56. When the cleaning drive source 42 is activated, it drives the transmission crank 52 to rotate, which in turn drives the transmission slider 51 and the cleaning scraper 43 to reciprocate back and forth through the first transmission shaft 53, the fisheye connector 56, the transmission connecting rod 55, and the second transmission shaft 54.

[0129] Preferably, such as Figure 12 and Figure 13As shown, the cleaning transmission assembly also includes two third guide shafts 57 extending straight back and forth along the moving direction of the transmission slider 51. Both third guide shafts 57 are fixed to the cleaning frame 41, and the transmission slider 51 is movably supported and mounted on the third guide shafts 57. The guiding cooperation between the third guide shafts 57 and the transmission slider 51 improves the smoothness of the transmission slider 51's back-and-forth movement, better ensuring the cleaning effect of the cleaning scraper 43 on the tongue and groove 11 and sealing groove 12 of the mold edge of the tube mold 10. Of course, in other embodiments, the number of third guide shafts 57 can also be different, such as one or three. Furthermore, if the third guide shaft 57 is a circular shaft, the shaft hole in the transmission slider 51 that mates with the third guide shaft 57 is a circular hole; or, if the third guide shaft 57 is a rectangular shaft, the shaft hole in the transmission slider 51 that mates with the third guide shaft 57 is a rectangular hole. The connection structure between the transmission slider 51 and the third guide shaft 57 can be as follows: the transmission slider 51 is mounted on the third guide shaft 57 in a way that allows it to move back and forth via a linear bearing, thereby achieving a sliding fit between the two; or, the transmission slider 51 and the third guide shaft 57 can achieve a sliding fit through a dovetail groove structure.

[0130] Furthermore, such as Figures 15 to 17 As shown, the tube mold cleaning mechanism 40 also includes a blade fixing assembly connected between the transmission slider 51 and the cleaning scraper 43. The blade fixing assembly includes a scraper mounting block 61 and a scraper mounting plate 62; a blade fixing groove 511 is provided in the transmission slider 51, which passes through the transmission slider 51 from left to right and extends forward to the front end of the transmission slider 51; the scraper mounting block 61 includes a mounting block body 611 embedded in the blade fixing groove 511 and a plate fixing protrusion 612 extending forward from the mounting block body 611; the scraper mounting plate 62 is distributed on the front side of the scraper mounting block 61, and a mounting positioning groove 621 is provided at the upper end of the scraper mounting plate 62. The mounting positioning groove 621 is a U-shaped groove; the plate fixing protrusion 612 is inserted into the mounting positioning groove 621 to achieve positioning of the scraper mounting plate 62 during installation; the plate fixing protrusion 612 and the scraper mounting plate 62 are fixedly connected by several screws, thereby fixing the scraper mounting plate 62 to the scraper mounting block 61; and the cleaning scraper 43 is fixed to the lower end of the scraper mounting plate 62 by several screws.

[0131] Furthermore, the mounting structure of the scraper mounting block 61 body 611 in the blade fixing groove 511 of the transmission slider 51 is as follows: Figures 15 to 17As shown, the blade fixing assembly also includes blade fixing support shafts 63 extending vertically and scraper springs 64. The blade fixing support shafts 63 are distributed in the blade fixing groove 511 and fixed to the transmission slider 51. The mounting block body 611 is vertically and movably supported and mounted on the blade fixing support shafts 63 via an oil-free bushing. The scraper spring 64 abuts against the top of the transmission slider 51 and the mounting block body 611, thereby vertically and flexibly embedding the mounting block body 611 of the scraper mounting block 61 into the blade fixing groove 511 of the transmission slider 51. Thus, during the cleaning process, the scraper spring 64 acts on the scraper mounting block 61, causing the cleaning scraper 43 to firmly press against the tongue and groove surface 11 and sealing groove 12 of the tube mold 10; however, when encountering protruding hard objects, the cleaning scraper 43 is allowed to float upwards a certain distance, making the cleaning scraper 43 durable, reducing the failure rate, and improving its adaptability to the tube mold 10. Preferably, there are two blade fixing support shafts 63, distributed on the left and right sides of the scraper spring 64. The top of the mounting block body 611 has a blind hole, and the lower part of the scraper spring 64 is housed in the blind hole of the mounting block body 611. In addition, the cleaning scraper 43 is made of carbon steel, which has good rigidity and improves the service life of the cleaning scraper 43.

[0132] Furthermore, such as Figures 10 to 12 ,as well as Figure 18 As shown, the pipe mold cleaning mechanism 40 also includes a guide bracket 71 fixed to the bottom of the cleaning frame 41, and several guide wheels 72 rotatably mounted on the guide bracket 71, arranged in a front-to-back pattern. Each guide wheel 72 includes a wheel body 721 and a wheel flange 722 protruding from the wheel body 721. During the cleaning process of the pipe mold 10, the wheel body 721 and the tongue-and-groove surface 11 of the pipe mold 10 roll into each other, and the wheel flange 722 is located in and rolls into the sealing groove 12 of the pipe mold 10. Thus, the guide wheels 72 achieve overall guidance of the pipe mold cleaning mechanism 40.

[0133] In summary, the working principle of the automated pipe mold cleaning system with the above structure is as follows:

[0134] 1. The transfer flatcar 21 on the target production line moves forward, bringing the tube mold 10 on it forward toward the tube mold cleaning equipment 30; when the first detection sensor 91 detects the front end of the tube mold 10, it means that the tube mold 10 has entered the cleaning operation area, the transfer flatcar 21 stops moving forward, and the tube mold 10 stops at the designated position.

[0135] 2. The X-axis drive motor 341 is activated, driving the left and right Z-axis trusses 33 and the tube mold cleaning mechanism 40 to move along the X-axis truss 32 to the top of the target production line;

[0136] 3. Two vision cameras 80 respectively capture images of the left and right mold edges of the tube mold 10, and obtain the X-axis coordinates of the left and right mold edges of the tube mold 10 in the left and right directions and the Z-axis coordinates in the up and down directions; the Z-axis truss 33 and the tube mold cleaning mechanism 40 move into position in the left and right directions according to the X-axis coordinates of the mold edges of the tube mold 10, and the tube mold cleaning mechanism 40 descends into position in the up and down directions according to the Z-axis coordinates of the mold edges of the tube mold 10.

[0137] 4. The cleaning drive source 42 in the tube mold cleaning mechanism 40 is activated and the blade is lowered; cleaning begins; at the same time, the transfer flatcar 21 moves the tube mold 10 forward, and the cleaning scrapers 43 in the left and right tube mold cleaning mechanisms 40 clean the tongue and groove surfaces 11 and sealing grooves 12 on the left and right sides of the tube mold 10.

[0138] 5. When the first detection sensor 91 detects the tension plate at the rear end of the tube mold 10, the transfer flatcar 21 stops moving forward, and the tube mold 10 stops at the designated position; the cleaning drive source 42 in the tube mold cleaning mechanism 40 stops operating, the blade is lifted, and the cleaning ends.

[0139] 6. The tube mold cleaning mechanism 40 moves upward and resets, and the Z-axis truss 33 moves and resets along the X-axis truss 32;

[0140] 7. The transfer flatcar 21 moves the pipe mold 10 forward, and the pipe mold 10 leaves the cleaning operation area.

[0141] In summary, this application achieves multi-span cleaning of the pipe mold 10 on multiple production lines, effectively cleaning the tongue and groove surfaces 11 and sealing grooves 12 on the edges of the pipe mold 10. It also adapts to the left-right and up-down tilting of the pipe mold 10, resulting in good cleaning effect, high cleaning efficiency, reliable overall structure, and good adaptability to the pipe mold 10. This significantly improves the quality of pipe mold 10 cleaning, which is beneficial for the fully automated and unmanned operation of prestressed concrete pipe pile production lines and meets the development needs of automated production equipment. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.
