[0001] The utility model relates to the technical field of prestressed pipe pile production, in particular to an adaptive pipe mold cleaning mechanism. Background Art

[0002] Usually, the pipe mold used to produce prestressed pipe piles consists of an upper mold and a lower mold. During production, the slurry is injected into the lower mold and then the mold is closed. After that, the prestressed pipe piles are obtained after tensioning, centrifugation, steaming, demoulding and other processes. After the whole set of processes are completed, the upper and lower molds of the pipe mold need to be cleaned to ensure the quality of the prestressed pipe piles when they are made next time.

[0003] At present, there are two ways to clean the pipe mold: 1. Manual cleaning; manually use a brush to clean the pipe mold, but this method has a low degree of automation, is time-consuming and labor-intensive, and has low cleaning efficiency. 2. Automatic cleaning by cleaning equipment; the cleaning equipment is equipped with a frame, a brush rack that can be lifted and lowered on the frame, a brush plate assembly installed on the brush rack, and a brush plate driving mechanism installed on the brush rack. The brush plate driving mechanism drives the brush plate assembly to rotate to clean the pipe mold; however, the brush plate assembly is mainly used to clean the inner wall surface of the pipe mold, and cannot clean the tongue and groove surface and sealing groove of the edge of the pipe mold well.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0068] The present application provides an adaptive pipe mold cleaning mechanism, which is used in the pipe mold cleaning process in the production process of concrete prestressed pipe piles, specifically for cleaning the groove surface 130 and the sealing groove 140 of the pipe mold edge. For the convenience of description, the length direction of the pipe mold is defined as the front-to-back direction, the horizontal radial direction of the pipe mold is defined as the left-right direction, and the vertical diameter direction of the pipe mold is defined as the up-down direction.

[0069] like Figure 1 and Figure 2 As shown, the adaptive pipe mold cleaning mechanism involved in the present application includes a mounting base 10, a floating connection block 20, a cleaning frame 30, a vertical floating assembly 40, a horizontal floating assembly 50, a cleaning drive source 60 installed on the cleaning frame 30, a cleaning transmission assembly, and a cleaning component movably installed on the cleaning frame 30. The floating connection block 20 is movably installed on the mounting base 10 along the vertical diameter of the pipe mold through the vertical floating assembly 40, and the cleaning frame 30 is movably installed on the floating connection block 20 along the horizontal radial direction of the pipe mold through the horizontal floating assembly 50. The cleaning drive source 60 is transmission-connected to the cleaning component through the cleaning transmission assembly.

[0070] The pipe mold to be cleaned is positioned and held on a flat cart in the workshop. The flat cart can move forward and backward, driving the pipe mold to move forward and backward together. The adaptive pipe mold cleaning mechanism is integrally installed on the lifting frame of the pipe mold cleaning equipment via the mounting base 10; when the cleaning operation starts, the lifting frame of the pipe mold cleaning equipment descends, driving the adaptive pipe mold cleaning mechanism to be in a descending state, and the flat cart drives the pipe mold to move toward the adaptive pipe mold cleaning mechanism in the front-to-back direction. When the pipe mold moves to the adaptive pipe mold cleaning mechanism, as shown in FIG. Figure 10As shown, the cleaning component is in contact with the part of the pipe mold to be cleaned. The cleaning drive source 60 drives the cleaning component to move through the cleaning transmission component, realizing the automatic cleaning of the pipe mold. In particular, during the cleaning process, the floating connection block 20 can float up and down relative to the mounting base 10 through the vertical floating component 40, and the cleaning frame 30 can float left and right relative to the floating connection block 20 through the horizontal floating component 50. Then, under the combined action of the vertical floating component 40 and the horizontal floating component 50, the cleaning frame 30 can float up and down and left and right relative to the mounting base 10. And the cleaning component for cleaning the pipe mold is installed on the cleaning frame 30, finally realizing the up and down and left and right floating of the cleaning component, enabling the cleaning component to adapt to the inclination in the left and right directions and the up and down directions of the pipe mold during the cleaning process, ensuring reliable contact between the cleaning component and the part of the pipe mold to be cleaned, thus reliably guaranteeing the cleaning effect, greatly improving the quality of pipe mold cleaning, being conducive to the fully automatic unmanned operation of the prestressed pipe pile automatic production line, and meeting the development requirements of automatic production equipment.

[0071] Furthermore, the preferred structure of the vertical floating component 40 is as follows: As Figure 3 and Figure 4 shown, the vertical floating component 40 includes a first guide shaft 41 and a first spring 42 that both extend vertically. The first guide shaft 41 is supported in the mounting base 10 by an oil-free bushing so as to be movable up and down. The lower end of the first guide shaft 41 is fixed in the floating connection block 20. The upper end of the first spring 42 abuts against the bottom of the mounting base 10, and the lower end of the first spring 42 abuts against the top of the floating connection block 20. The first spring 42 is preferably sleeved on the first guide shaft 41. Under the action of the first guide shaft 41 and the first spring 42, the up and down floating of the floating connection block 20 is realized, and thus the up and down floating of the cleaning frame 30 and the cleaning component is realized. In addition, there are two groups of vertical floating components 40, arranged side by side front and back.

[0072] Furthermore, the preferred structure of the horizontal floating component 50 is as follows: As Figure 5 and Figure 6 shown, the horizontal floating component 50 includes a second guide shaft 51 and a second spring 52 that both extend horizontally. The second guide shaft 51 is supported in the floating connection block 20 by an oil-free bushing so as to be movable left and right. Both ends of the second guide shaft 51 are fixed in the cleaning frame 30. Second springs 52 are arranged on both the left and right sides of the floating connection block 20. The cleaning frame 30 is of a frame structure, and the floating connection block 20 is arranged inside the cleaning frame 30. The inner end of the second spring 52 abuts against the floating connection block 20, and the outer end of the second spring 52 abuts against the cleaning frame 30. Under the action of the second guide shaft 51 and the second spring 52, the left and right floating of the cleaning frame 30 is realized, and thus the left and right floating of the cleaning component is realized.

[0073] Preferably, as Figure 5 andFigure 6 As shown, there are two second guide shafts 51, which are arranged side by side in the front-rear direction on the front and rear sides of the second spring 52. That is, the second spring 52 is not sleeved on the second guide shaft 51, but is arranged side by side with the second guide shaft 51. The installation structure of the second spring 52 is as follows: the lateral floating assembly 50 further includes a spring fixing sleeve 53 facing the second spring 52 and fixed to the cleaning frame 30. Spring positioning holes facing the spring fixing sleeve 53 are provided on both the left and right sides of the floating connection block 20. The inner and outer ends of the second spring 52 are respectively accommodated in the spring positioning holes and the spring fixing sleeve 53.

[0074] Furthermore, as Figure 10 shown, in this application, the parts of the pipe mold to be cleaned are the rabbet surface 130 and the sealing groove 140 on the edge of the pipe mold. Based on this, as Figure 1 and Figure 2 shown, the cleaning transmission assembly includes a transmission slider 71 that is installed on the cleaning frame 30 so as to be reciprocally movable back and forth along the length direction of the pipe mold, and the cleaning part is a cleaning scraper 80 installed on the transmission slider 71. As Figure 7 shown, the cleaning scraper 80 includes a scraper body 81, a first scraping blade 82 provided at the bottom of the scraper body 81, a scraper protrusion 83 protruding downward from the bottom of the scraper body 81, and a second scraping blade 84 provided at the bottom of the scraper protrusion 83. The first scraping blade 82 is used to clean the rabbet surface 130 on the edge of the pipe mold, and the scraper protrusion 83 and the second scraping blade 84 are used to clean the sealing groove 140 on the edge of the pipe mold. During the cleaning process of the cleaning scraper 80, the first scraping blade 82 at the bottom of the cleaning scraper 80 abuts against the rabbet surface 130 on the edge of the pipe mold and the two are in contact and cooperation. The scraper protrusion 83 at the bottom of the cleaning scraper 80 is located in the sealing groove 140 on the edge of the pipe mold, and the second scraping blade 84 abuts against the bottom surface of the sealing groove 140 and the two are in contact and cooperation. Along with the movement of the flat car driving the pipe mold, the cleaning drive source 60 acts, and drives the transmission slider 71 and the cleaning scraper 80 to reciprocally move back and forth through the cleaning transmission assembly. Then, the first scraping blade 82 at the bottom of the cleaning scraper 80 cleans the rabbet surface 130 on the edge of the pipe mold, and the second scraping blade 84 at the bottom of the cleaning scraper 80 cleans the sealing groove 140. In this way, in this application, the rabbet surface 130 and the sealing groove 140 on the edge of the pipe mold are effectively cleaned by the first scraping blade 82 and the second scraping blade 84 at the bottom of the cleaning scraper 80, and the cleaning effect is good and the cleaning efficiency is high.

[0075] Furthermore, as Figure 1 and Figure 5As shown, the cleaning drive source 60 is a motor, and the cleaning transmission assembly adopts a crank - connecting rod mechanism. Specifically, the cleaning transmission assembly further includes a transmission crank 72 fixed on the motor shaft of the cleaning drive source 60, a first transmission shaft 73 fixed in the transmission crank 72, a second transmission shaft 74 fixed in the transmission slider 71, a transmission connecting rod 75, and a spherical eye joint 76. The motor shaft of the cleaning drive source 60, the first transmission shaft 73, and the second transmission shaft 74 are parallel and all extend straight left and right. One end of the transmission connecting rod 75 is rotatably fitted with the first transmission shaft 73 through the spherical eye joint 76, and the other end of the transmission connecting rod 75 is rotatably fitted with the second transmission shaft 74 through the spherical eye joint 76. When the cleaning drive source 60 operates, it drives the transmission crank 72 to rotate, and through the first transmission shaft 73, the spherical eye joint 76, the transmission connecting rod 75, and the second transmission shaft 74, it drives the transmission slider 71 and the cleaning scraper 80 to reciprocate back and forth.

[0076] Preferably, as Figure 4 and Figure 5 shown, the cleaning transmission assembly further includes a third guide shaft 77 that extends straight back and forth along the moving direction of the transmission slider 71. There are two third guide shafts 77 arranged vertically. Both of the two third guide shafts 77 are fixed to the cleaning frame 30, and the transmission slider 71 is supported and installed on the third guide shaft 77 so as to be movable back and forth. Through the guiding cooperation between the third guide shaft 77 and the transmission slider 71, the smoothness of the forward and backward movement of the transmission slider 71 is improved, and the cleaning effect of the cleaning scraper 80 on the rabbet surface 130 and the sealing groove 140 of the pipe die edge is better guaranteed. Of course, in other embodiments, the number of the third guide shafts 77 can also be set to other numbers, such as one or three. In addition, if the third guide shaft 77 is a circular shaft, the shaft hole in the transmission slider 71 that cooperates with the third guide shaft 77 is a circular hole; or if the third guide shaft 77 is a rectangular shaft, the shaft hole in the transmission slider 71 that cooperates with the third guide shaft 77 is a rectangular hole. The combined structure between the transmission slider 71 and the third guide shaft 77 can be: the transmission slider 71 is installed on the third guide shaft 77 through a linear bearing so as to be movable back and forth, realizing the sliding fit between the two; or the sliding fit between the transmission slider 71 and the third guide shaft 77 is realized through a dovetail groove structure.

[0077] Furthermore, as Figures 7 to 9As shown in the figure, the adaptive tube mold cleaning mechanism further includes a tool fixing component connected between the driving slider 71 and the cleaning scraper 80. The tool fixing component includes a scraper mounting block 91 and a scraper mounting plate 92; a tool fixing groove 711 is formed in the driving slider 71, and the tool fixing groove 711 penetrates through the driving slider 71 from left to right and extends forward to the front end of the driving slider 71; the scraper mounting block 91 includes a mounting block body 911 embedded in the tool fixing groove 711 and a plate fixing protrusion 912 extending forward from the mounting block body 911; the scraper mounting plate 92 is distributed on the front side of the scraper mounting block 91, and a mounting positioning groove 921 is formed at the upper end of the scraper mounting plate 92, and the mounting positioning groove 921 is a U-shaped groove; the plate fixing protrusion 912 is inserted into the mounting positioning groove 921 to realize the positioning during the installation of the scraper mounting plate 92; the plate fixing protrusion 912 and the scraper mounting plate 92 are fixedly connected by several screws, thereby fixing the scraper mounting plate 92 to the scraper mounting block 91; and the cleaning scraper 80 is fixed to the lower end of the scraper mounting plate 92 by several screws.

[0078] Furthermore, the installation structure of the mounting block body 911 of the scraper mounting block 91 in the tool fixing groove 711 of the driving slider 71 is as follows: As Figures 7 to 9 shown in the figure, the tool fixing component further includes a tool fixing support shaft 93 and a scraper spring 94 that both extend vertically. The tool fixing support shaft 93 is distributed in the tool fixing groove 711 and fixed to the driving slider 71. The mounting block body 911 is supported and installed on the tool fixing support shaft 93 through an oil-free bushing so as to be movable up and down. The scraper spring 94 abuts between the driving slider 71 and the top of the mounting block body 911, thereby embedding the mounting block body 911 of the scraper mounting block 91 in the tool fixing groove 711 of the driving slider 71 in a floating manner up and down. In this way, during the cleaning process, the scraper spring 94 acts on the scraper mounting block 91, so that the cleaning scraper 80 tightly abuts against the rabbet surface 130 and the sealing groove 140 of the tube mold; but when encountering a protruding hard object, it also allows the cleaning scraper 80 to float up a certain distance, making the cleaning scraper 80 durable, reducing the failure rate, and improving the adaptability to the tube mold. Preferably, there are two tool fixing support shafts 93, which are distributed on the left and right sides of the scraper spring 94. A blind hole is formed at the top of the mounting block body 911, and the lower section of the scraper spring 94 is accommodated in the blind hole of the mounting block body 911. In addition, the cleaning scraper 80 is made of carbon steel, which has good rigidity and improves the service life of the cleaning scraper 80.

[0079] Furthermore, as Figures 2 to 4 and Figure 10As shown, the adaptive pipe mold cleaning mechanism further includes a guiding bracket 110 fixed to the bottom of the cleaning frame 30 and several guiding wheels 120 rotatably mounted on the guiding bracket 110, and the several guiding wheels 120 are arranged front and back. The guiding wheel 120 includes a wheel main body portion 121 and a wheel flange portion 122 protruding from the wheel main body portion 121; during the cleaning process of the pipe mold, the wheel main body portion 121 is in rolling cooperation with the rabbet surface 130 of the pipe mold edge, and the wheel flange portion 122 is located in the sealing groove 140 of the pipe mold edge and is in rolling cooperation with the sealing groove 140. In this way, the overall guiding of the adaptive pipe mold cleaning mechanism is realized through the guiding wheel 120.

[0080] In summary, the present application can effectively clean the rabbet surface 130 and the sealing groove 140 of the pipe mold edge, and can adapt to the left-right direction inclination and the up-down direction inclination of the pipe mold. The cleaning effect is good, the cleaning efficiency is high, the overall structure is reliable, the adaptability to the pipe mold is good, the quality of pipe mold cleaning is greatly improved, which is beneficial to the fully automatic unmanned operation of the prestressed pipe pile automatic production line and meets the development requirements of automatic production equipment.
