Description

Technical Field

[0001] The utility model relates to the technical field of prestressed pipe pile production, in particular to a pipe mold cleaning roller brush mechanism and a pipe mold cleaning device equipped with the pipe mold cleaning roller brush 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 drive mechanism installed on the brush rack. The brush plate drive mechanism drives the brush plate assembly to rotate to clean the pipe mold; however, there are pipe mold locating pins on the pipe mold. When the brush plate assembly of the cleaning equipment encounters the protruding pipe mold locating pin during the cleaning process, it cannot avoid the pipe mold locating pin, resulting in a collision between the brush plate assembly and the pipe mold locating pin, resulting in a high failure rate of the cleaning equipment, which is not conducive to the fully automatic and unmanned operation of the prestressed pipe pile automated production line.

[0004] In view of the above-mentioned shortcomings of the prior art, the technical problem to be solved by the utility model is to provide a tube mold cleaning roller brush mechanism, which can automatically clean the tube mold and avoid the tube mold positioning pin.

[0005] To achieve the above-mentioned purpose, the utility model provides a pipe mold cleaning roller brush mechanism, including a frame, a cleaning drive source installed on the frame, a cleaning transmission assembly, a cleaning roller brush, an avoidance mounting plate, and a reset assembly.

[0006] A preferred embodiment of the above technical solution is as follows: the reset assembly comprises a tension spring, and two ends of the tension spring are respectively connected to the frame and the avoidance mounting plate.

[0007] A preferred embodiment of the above technical solution is as follows: the reset assembly comprises an elastic band, and two ends of the elastic band are respectively connected to the frame and the avoidance mounting plate.

[0008] The preferred solution of the above technical solution is as follows: The tube mold cleaning brush mechanism further includes a first bearing seat fixed on the outer peripheral side of the frame, a second bearing seat fixed on the upper end of the avoidance mounting plate, a third bearing seat fixed on the lower end of the avoidance mounting plate, a first pin shaft, and a second pin shaft. The first pin shaft is rotatably supported in the first bearing seat and the second bearing seat, the second pin shaft is rotatably supported in the third bearing seat, and the cleaning brush is fixed on the second pin shaft.

[0009] The preferred solution of the above technical solution is as follows: The cleaning driving source is a motor. The cleaning transmission assembly includes a first synchronous pulley unit and a second synchronous pulley unit. The first synchronous pulley unit includes a first pulley fixed on the motor output shaft of the cleaning driving source, a second pulley fixed on the first pin shaft, and a first synchronous belt connected to the outer peripheries of the first pulley and the second pulley. The second synchronous pulley unit includes a third pulley fixed on the first pin shaft, a fourth pulley fixed on the second pin shaft, and a second synchronous belt connected to the outer peripheries of the third pulley and the fourth pulley.

[0010] The preferred solution of the above technical solution is as follows: The first synchronous pulley unit and the second synchronous pulley unit are arranged on the same side of the frame and the avoidance mounting plate.

[0014] In this application, the cleaning driving source drives the cleaning brush to rotate through the cleaning transmission assembly to achieve automatic cleaning of the tube mold. During the cleaning process, when the cleaning brush encounters the tube mold positioning pin, based on the fact that the avoidance mounting plate on which the cleaning brush is installed is rotatable relative to the frame, the tube mold positioning pin is allowed to lift the cleaning brush, enabling the cleaning brush to cross over the tube mold positioning pin and achieve automatic avoidance of the tube mold positioning pin. After crossing over the tube mold positioning pin, the avoidance mounting plate and the cleaning brush are driven by the reset assembly to return to their original positions.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. 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.

[0038] The utility model provides a tube mold cleaning roller brush mechanism, and a tube mold cleaning device equipped with the tube mold cleaning roller brush mechanism, which are used in the tube mold cleaning process in the production process of concrete prestressed tube piles, specifically for cleaning the inner surface of the tube mold, that is, cleaning the inner surface of the upper mold and the inner surface of the lower mold. For the convenience of description, the length direction of the tube mold is defined as the front-to-back direction. The tube mold cleaning device includes a fixed frame, a lifting drive source, a lifting frame that can be lifted and lowered on the fixed frame, and a tube mold cleaning roller brush mechanism, the lifting drive source is connected to the lifting frame in a transmission manner to drive the lifting frame to rise or fall, and the tube mold cleaning roller brush mechanism is installed on the lifting frame.

[0039] like Figures 1 to 3As shown, the pipe mold cleaning roller brush mechanism involved in the present application includes a frame 10, a cleaning drive source 20 installed on the frame 10, a cleaning transmission assembly 30, a cleaning roller brush 120, an avoidance mounting plate 40, and a reset assembly; wherein, the frame 10 is installed on a lifting frame, thereby the pipe mold cleaning roller brush mechanism is installed as a whole on the lifting frame; the cleaning drive source 20 is connected to the cleaning roller brush 120 through the cleaning transmission assembly 30, driving the cleaning roller brush 120 to rotate; the upper end of the avoidance mounting plate 40 is rotatably mounted on the frame 10, the cleaning roller brush 120 is rotatably mounted on the lower end of the avoidance mounting plate 40, and the reset assembly is connected between the frame 10 and the avoidance mounting plate 40.

[0040] In the pipe mold cleaning device, the lifting frame and the pipe mold cleaning roller brush mechanism are driven to rise or fall by the lifting drive source, and the cleaning roller brush 120 is moved away from or close to the inner surface of the pipe mold accordingly. When the cleaning roller brush 120 is lowered until it contacts the inner surface of the pipe mold, the lifting drive source stops; then, the cleaning drive source 20 is activated, and the cleaning roller brush 120 is driven to rotate through the cleaning transmission assembly 30, and the translation of the pipe mold in the front and rear directions is driven by the translation trolley to realize automatic cleaning of the inner surface of the pipe mold. During the cleaning process, when the cleaning roller brush 120 hits the pipe mold locating pin, the avoidance mounting plate 40 on which the cleaning roller brush 120 is installed can rotate relative to the frame 10, thereby allowing the pipe mold locating pin to lift up the cleaning roller brush 120, and the avoidance mounting plate 40 rotates around the rotation center between it and the frame 10, so that the cleaning roller brush 120 can pass over the pipe mold locating pin, and automatically avoid the pipe mold locating pin; after passing over the pipe mold locating pin, the avoidance mounting plate 40 and the cleaning roller brush 120 are driven by the reset component to reset, and the cleaning roller brush 120 contacts the inner surface of the pipe mold again. Therefore, the present application can automatically clean the pipe mold and avoid the pipe mold locating pin, with high cleaning efficiency and good effect, and can reduce the failure rate caused by the collision of the cleaning roller brush 120 with the pipe mold locating pin, which is well adapted to the development needs of prestressed pipe pile automated production equipment, and is ultimately conducive to the fully automatic unmanned operation of the prestressed pipe pile automated production line.

[0041] Furthermore, if Figures 1 to 3 As shown, the reset assembly includes a tension spring 50, and the two ends of the tension spring 50 are respectively connected to the frame 10 and the avoidance mounting plate 40; when avoiding the pipe mold positioning pin, the tension spring 50 is stretched; after passing over the pipe mold positioning pin, the spring force of the tension spring 50 prompts the avoidance mounting plate 40 to rotate in the opposite direction until the cleaning roller brush 120 contacts the inner surface of the pipe mold again. Alternatively, the reset assembly includes an elastic belt, and the two ends of the elastic belt are respectively connected to the frame 10 and the avoidance mounting plate 40, and the elastic belt provides the restoring force of the avoidance mounting plate 40.

[0042] Further, the rotation structure between the avoidance mounting plate 40 and the frame 10, and the rotation structure between the cleaning roller brush 120 and the avoidance mounting plate 40 are preferably: Figure 1 andFigure 2 As shown, the pipe mold cleaning brush mechanism further includes a first bearing seat 60 fixed to the outer peripheral side of the frame 10, a second bearing seat 70 fixed to the upper end of the avoidance mounting plate 40, a third bearing seat 80 fixed to the lower end of the avoidance mounting plate 40, a first pin shaft 90, and a second pin shaft 110. The first pin shaft 90 and the second pin shaft 110 are parallel to each other and both extend horizontally. The first pin shaft 90 is rotatably supported in the first bearing seat 60 and the second bearing seat 70, so that the upper end of the avoidance mounting plate 40 is rotatably mounted on the frame 10; the second pin shaft 110 is rotatably supported in the third bearing seat 80, and the cleaning brush 120 is fixed to the second pin shaft 110, so that the cleaning brush 120 is rotatably mounted at the lower end of the avoidance mounting plate 40. Of course, in other embodiments, the rotational support of the first pin shaft 90 in the frame 10 and the avoidance mounting plate 40, and the rotational support of the second pin shaft 110 in the avoidance mounting plate 40 can also adopt a structure of shaft-hole fit.

[0043] Further, as Figures 1 to 3 shown, the cleaning driving source 20 is a motor, and the cleaning transmission assembly 30 includes a first synchronous pulley unit and a second synchronous pulley unit. The first synchronous pulley unit includes a first pulley 31 fixed to the motor output shaft of the cleaning driving source 20, a second pulley 32 fixed to the first pin shaft 90, and a first synchronous belt 33 connected to the outer peripheries of the first pulley 31 and the second pulley 32. The second synchronous pulley unit includes a third pulley 34 fixed to the first pin shaft 90, a fourth pulley 35 fixed to the second pin shaft 110, and a second synchronous belt 36 connected to the outer peripheries of the third pulley 34 and the fourth pulley 35. The first synchronous belt 33 and the second synchronous belt 36 can be flat belts, or V-belts, or round belts.

[0044] Further, as Figure 1 and Figure 2 shown, the first synchronous pulley unit and the second synchronous pulley unit are arranged on the same side of the frame 10 and the avoidance mounting plate 40, making the overall structure compact. In addition, the connection between the second pulley 32 and the first pin shaft 90, the connection between the third pulley 34 and the first pin shaft 90, and the connection between the fourth pulley 35 and the second pin shaft 110 are all fixed by key connections; of course, screw locking can also be used.

[0045] In summary, the working principle of the pipe mold cleaning brush mechanism with the above structure is as follows.

[0046] After the cleaning brush roller 120 contacts the inner surface of the pipe mold, the cleaning drive source 20 provides rotational power to drive the first pulley 31 to rotate. The first pulley 31 drives the second pulley 32 to rotate through the first synchronous belt 33. The first pin shaft 90 and the third pulley 34 rotate synchronously with the second pulley 32. The third pulley 34 drives the fourth pulley 35 to rotate through the second synchronous belt 36. The second pin shaft 110 and the cleaning brush roller 120 rotate synchronously with the fourth pulley 35, realizing the automatic cleaning of the inner surface of the pipe mold. When the cleaning brush roller 120 touches the pipe mold positioning pin, the pipe mold positioning pin jacks up the cleaning brush roller 120, causing the avoidance mounting plate 40 to rotate relative to the frame 10 around the first pin shaft 90. The tension spring 50 is stretched until the cleaning brush roller 120 passes over the pipe mold positioning pin, automatically avoiding the pipe mold positioning pin. After that, the spring force of the tension spring 50 causes the avoidance mounting plate 40 to rotate in the opposite direction relative to the frame 10 around the first pin shaft 90 until the cleaning brush roller 120 contacts the inner surface of the pipe mold again.

[0047] In summary, the utility model effectively overcomes various shortcomings in the prior art and has high industrial utilization value.

[0048] The above embodiments are only illustrative of the principles and effects of the utility model, and are not intended to limit the utility model. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the utility model should still be covered by the claims of the utility model.
