A suspended roller cement pipe making machine

Abstract

This invention relates to the field of suspension roller mill equipment technology, and discloses a suspension roller type cement pipe making machine. It mainly utilizes a connecting sleeve on the outside of the suspension roller shaft, and the rotation of the suspension roller shaft causes a telescopic pipe to push out a pre-compression pipe. This ensures that during pipe mold operation, the suspension roller shaft and the pre-compression pipe work synchronously to reach the upper and lower inner walls of the pipe mold, thus preventing the pipe mold from shaking during rotation. Furthermore, the outward pushing of both the pre-compression pipe and the suspension roller shaft ensures that both compress the concrete in the pipe mold, enhancing the compaction between concrete particles and accelerating the compaction efficiency. The intervention of the pre-compression pipe also prevents uneven concrete distribution within the pipe mold from causing jumping, ultimately avoiding shaking and jumping during pipe mold rotation.

Description

Technical Field

[0001] The invention relates to the technical field of suspension roller machine equipment, in particular to a suspension roller cement pipe making machine. Background Art

[0002] Suspended roller cement pipe making machine refers to a machine in which the speed regulating motor drives the pipe mold to rotate through the suspension roller shaft. The concrete fed into the pipe mold also rotates together under the action of centrifugal force. When the thickness of the fed concrete material exceeds the height of the retaining ring, the concrete on the pipe wall passing vertically above the suspension roller shaft is subjected to the roller pressure of the suspension roller shaft, and is compacted and formed under the joint action of the suspension roller shaft and the inner wall of the pipe mold.

[0003] During the feeding process, the existing pipe making machine feeds concrete into the pipe mold. Only when the concrete is transported to the rotating roller shaft at the top can the concrete be pressed. As a result, when the pipe mold drives the cement to rotate, some particles in the cement will be thrown outward under the action of centrifugal force, posing a safety hazard to external construction workers. On the other hand, when the pipe mold is fed unevenly, the load between the two ends of the pipe mold will change, causing the pipe mold to shake. At the same time, when too much concrete is locally accumulated, the pipe mold will tend to jump upward when passing through the suspension roller shaft, causing the pipe mold to shake, which not only reduces its working effect, but also causes a safety hazard to nearby workers. Summary of the invention

[0004] In view of the shortcomings of the existing suspended roller cement pipe making machine mentioned in the background technology during use, the present invention provides a suspended roller cement pipe making machine, which has the advantage of avoiding shaking and jumping when the pipe mold rotates, and solves the technical problems raised in the above background technology.

[0005] The present invention provides the following technical solution: a suspension roller cement pipe making machine, comprising a suspension roller shaft, frames are movably installed on both sides of the suspension roller shaft, and a pipe mold is movably installed on the side wall of the suspension roller shaft, the side walls of the suspension roller shaft are respectively provided with connecting sleeves connected by ball bearings, and the connecting sleeves are located on both sides of the pipe mold, and telescopic pipes are fixedly installed on the side walls of the connecting sleeves, and pre-pressure pipes are movably installed between the telescopic pipes, and a driving pipe located below the suspension roller shaft is movably installed on the inner wall of the connecting sleeve, and the driving pipe is movably connected to the side wall of the suspension roller shaft, and the number of the driving pipes is set to There are two of them, one end of the two driving tubes is installed corresponding to the outer sides of the two connecting sleeves, one end of the two driving tubes is movably installed with a fixed tube for connecting the two driving tubes, the side wall of the fixed tube is fixedly installed with an infusion pipeline for fixing the fixed tube, and the two ends of the infusion pipeline are respectively fixedly installed with the connecting sleeve, one end of the infusion pipeline passes through the connecting sleeve and then passes through the frame, one end of the infusion pipeline is connected to the on-off valve, and the inner wall of the driving tube is fixedly installed with an infusion auger for filling liquid medium into the telescopic pipeline to achieve the extension of the telescopic pipeline.

[0006] Preferably, the outer wall of the driving tube is provided with anti-slip threads.

[0007] Preferably, a storage box located between the preloading pipe and the fixed pipe is fixedly installed on the side wall of the telescopic pipe, a storage cavity for storing concrete is provided in the inner wall of the storage box, an opening for outputting concrete is provided at the bottom of the storage box, and the opening is located above the preloading pipe.

[0008] Preferably, a scraper block slidably connected to the pre-pressing tube is provided at the bottom of the material storage box, and a residual material channel located above the scraper block is opened at the bottom of the material storage box, and one end of the residual material channel is located at the opening of the material storage cavity.

[0009] Preferably, a cloth top block is movably mounted on the inner wall of the pre-compression tube, and an ejection spring for ejecting the cloth top block is fixedly mounted on the inner wall of the pre-compression tube. There are at least two cloth top blocks, and an arc-shaped portion for retracting the cloth top block is provided at the bottom of the storage box.

[0010] Preferably, a material baffle plate is movably mounted on the inner wall of the material storage cavity, and the number of the material baffle plates is two.

[0011] The present invention has the following beneficial effects:

[0012] 1. The present invention provides a connecting sleeve on the outside of the suspension roller shaft, and the telescopic pipe pushes out the prestressing pipe through the rotation of the suspension roller shaft, so as to ensure that when the pipe mold is working, the suspension roller shaft and the prestressing pipe are synchronously acted on the upper and lower inner walls of the pipe mold, thereby ensuring that the pipe mold will not shake during the rotation process. On the other hand, the prestressing pipe and the suspension roller shaft are both pushed outward to ensure that the suspension roller shaft and the prestressing pipe press the concrete in the pipe mold, enhance the compaction between the concrete, speed up the compaction efficiency, and through the intervention of the prestressing pipe, when the concrete in the pipe mold is unevenly distributed, there will be no jumping phenomenon, ultimately avoiding the shaking and jumping of the pipe mold when it rotates.

[0013] 2. The present invention provides a distribution top block in the preloading tube and a storage box above the preloading tube, thereby ensuring that during the working process, the storage cavity is filled with concrete, and the concrete is output to the inner wall of the tube mold when the distribution top block rotates. Since the rotation direction of the tube mold is relative to that of the distribution top block, the concrete output by the distribution top block will directly hit the concrete inside the tube mold, and a relative force is generated between the two, which not only prevents the concrete from being thrown out of the tube mold, but also makes it easier for the concrete to adhere to the concrete in the tube mold through the collision between the two. After that, the concrete in the tube mold will be directly fed into the preloading tube, and the concrete in the tube mold is pressed by the preloading tube, thereby avoiding the phenomenon that the concrete in the tube mold is thrown out to the outside of the tube mold due to centrifugal force during the upward transportation, thereby finally achieving the purpose of preventing the concrete from being thrown out.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] See also Figure 1-Figure 3 and Figure 6 A suspended roller cement pipe making machine comprises a suspended roller shaft 4, and a frame 1 for fixing is movably installed on both sides of the suspended roller shaft 4, and a pipe mold 10 for pipe making is movably installed on the side wall of the suspended roller shaft 4, and a connecting sleeve 9 connected by a ball bearing is provided on the side wall of the suspended roller shaft 4, and the connecting sleeve 9 is located on both sides of the pipe mold 10, and a telescopic pipe 2 is fixedly installed on the side wall of the connecting sleeve 9, and a pre-pressure pipe 11 for positioning and pressurizing is movably installed between the telescopic pipes 2, and at the same time, a driving pipe 6 located below the suspended roller shaft 4 is movably installed on the inner wall of the connecting sleeve 9, and the driving pipe 6 is movably connected to the side wall of the suspended roller shaft 4, and the number of the driving pipes 6 is set to two, one end of the two driving pipes 6 is installed corresponding to the outer sides of the two connecting sleeves 9, and a fixed pipe 7 is movably installed at one end of the two driving pipes 6 for connecting the two driving pipes 6, and through the fixed pipe The side wall of 7 is fixedly installed with an infusion pipeline 8 for fixing the fixed tube 7, and the two ends of the infusion pipeline 8 are fixedly installed with the connecting sleeve frame 9 respectively. One end of the infusion pipeline 8 passes through the connecting sleeve frame 9 and then passes through the frame 1, and is connected to the on-off valve 3 through one end of the infusion pipeline 8. At the same time, an infusion auger 5 for injecting liquid medium into the telescopic pipeline 2 to extend the telescopic pipeline 2 is fixedly installed on the inner wall of the driving tube 6, so as to ensure that during the operation, the driving tube 6 is driven to rotate by the suspension roller shaft 4, so that the infusion auger 5 transports the medium in the infusion pipeline 8 to the telescopic pipeline 2 during the rotation, thereby ensuring that the pre-stressing tube 11 is pressed downward, and then the inner wall of the pipe mold 10 is limited and anti-swayed, and the pre-stressing tube 11 is ejected by the liquid pressure generated by its own rotation, so it can be fixed for pipe molds 10 with different inner diameters, so as to achieve the purpose of adaptive positioning.

[0024] See also Figure 4In order to further enhance the transmission strength between the suspension roller shaft 4 and the driving tube 6, an anti-slip thread is provided on the outer wall of the driving tube 6 to ensure that there is sufficient transmission strength between the suspension roller shaft 4 and the driving tube 6 during the transmission process. When the preloading tube 11 is pushed into the pipe mold 10, the relative sliding between the driving tube 6 and the suspension roller shaft 4 causes the driving tube 6 to scrape the concrete on the outside of the suspension roller shaft 4.

[0025] See also Figure 4-Figure 5 In order to prevent the concrete fed into the pipe mold 10 from being easily thrown out, a storage box 12 located between the preloading pipe 11 and the fixed pipe 7 is fixedly installed on the side wall of the telescopic pipe 2, and a storage cavity 122 for storing concrete is provided in the inner wall of the storage box 12, and an opening for outputting concrete is provided at the bottom of the storage box 12, and the opening is located above the preloading pipe 11, so that the concrete dropped from the storage box 12 is thrown out to the inner wall of the pipe mold 10 through the rotation of the preloading pipe 11, so that the acceleration of the concrete by the preloading pipe 11 and the pipe mold The concrete in 10 is subjected to relative forces, so that the concrete between the two will adhere to each other after collision, and will then be compacted by the preloading tube 11, thereby avoiding the phenomenon of concrete in the tube mold 10 being thrown out. When there is no concrete in the tube mold 10 initially, because in the prior art, when the suspension roller shaft 4 contacts the tube mold 10, there is still a certain distance between the suspension roller shaft 4 and the inner wall of the tube mold 10, so as to achieve the thickness of the pipe after pipe making. Therefore, when there is less concrete or no concrete in the tube mold 10, it is restricted by the shape of the tube mold 10 itself, and the concrete in the tube mold 10 will not be thrown out.

[0026] See also Figure 4 and Figure 5 In order to remove the concrete adhered to the preloading tube 11, a scraper block 121 slidably connected to the preloading tube 11 is provided at the bottom of the storage box 12, and a residual material channel 120 located above the scraper block 121 is opened at the bottom of the storage box 12, and one end of the residual material channel 120 is located at the opening of the storage cavity 122, so as to ensure that after the scraper block 121 scrapes out the concrete, the concrete will be input into the opening of the storage cavity 122 through the residual material channel 120, so that the concrete can be recycled to avoid its waste.

[0027] See also Figure 4 and Figure 7In order to further increase the strength of concrete ejection in the storage chamber 122, a cloth top block 14 is movably installed on the inner wall of the preloading tube 11, and an ejection spring 15 for ejecting the cloth top block 14 is fixedly installed on the inner wall of the preloading tube 11. There are at least two cloth top blocks 14, and an arc-shaped portion for retracting the cloth top block 14 is provided at the bottom of the storage box 12, so as to ensure that the cloth top block 14 will not be interfered by movement when passing through the scraper block 121. At the same time, the scraper block 121 also scrapes the cloth top block 14, and the cloth top block 14 pushes the material in the storage chamber 122 to the inner wall of the pipe mold 10 more easily after extending.

[0028] See also Figure 5 In order to make all the concrete in the storage chamber 122 fall into the pipe mold 10, a baffle plate 13 is movably installed on the inner wall of the storage chamber 122, and the number of the baffle plates 13 is two, ensuring that the length of the storage chamber 122 output from the opening can be changed during the position change process, thereby further realizing that the concrete in the storage chamber 122 can be accurately fed into the pipe mold 10.

[0029] The working principle of the present invention is as follows: when in use, a frame 1 is taken out, and the pipe mold 10 is sleeved on the outside of the suspension roller shaft 4 through a lifting tool. Then, the suspension roller shaft 4 is limited by the frame 1, and the driving mechanism is started to realize the rotation of the suspension roller shaft 4. The driving mechanism and the lifting tool are not shown in the figure. Both are prior arts and are not described in detail here.

[0030] Afterwards, the rotation of the suspension roller shaft 4 will drive the synchronous rotation of the pipe mold 10, and the connection sleeve 9 will limit the pipe mold 10, so as to avoid the pipe mold 10 not crossing the connection sleeve 9 and moving to the two sides of the suspension roller shaft 4 during the rotation. At the same time, the driving tube 6 is driven to rotate by the suspension roller shaft 4, and during the rotation of the driving tube 6, the infusion auger 5 will output the hydraulic oil in the infusion pipeline 8 to the telescopic pipe 2. At this time, during the output of the pre-stressing tube 11 and the hydraulic oil, the telescopic pipe 2 will cause the pre-stressing tube 11 to continuously push downward until the pre-stressing tube 11 contacts the inner wall of the pipe mold 10, and through the continuous hydraulic pressure supply in the telescopic pipe 2, the pre-stressing tube 11 and the suspension roller shaft 4 are respectively pushed to the upper and lower parts of the inner wall of the pipe mold 10, and the pipe mold 10 is limited up and down, so as to avoid the shaking and jumping of the pipe mold 10 during operation.

[0031] Afterwards, the concrete is delivered to the storage box 12 in the form of a pipeline, and the required amount of concrete is stored in the storage box 12. Then, the pre-loading pipe 11 rotates, and the top cloth block 14 is ejected by the ejection spring 15, so that the top cloth block 14 pushes the concrete output from the storage chamber 122 to the inner wall of the pipe mold 10. Since the inner wall of the pipe mold 10 and the rotation direction of the top cloth block 14 are relative, when the concrete on the top cloth block 14 impacts the concrete in the pipe mold 10, due to the certain movement speed between the two, when the concrete on the top cloth block 14 hits the pipe mold 10, the concrete between the two will be attached to each other, thereby avoiding the phenomenon of concrete on the pipe mold 10 being thrown out. Through the collision between the two, at the same time, the phenomenon of concrete being thrown out only by the centrifugal force generated when the pipe mold 10 rotates is also slowed down.

[0032] After the concrete is thrown out of the tube mold 10, it will quickly pass through the pre-compression tube 11, and then the concrete in the tube mold 10 will be pressed together through the extrusion of the pre-compression tube 11. At the same time, when the top block 14 of the material distribution contacts the inner wall of the tube mold 10, the ejection spring 15 will be synchronously squeezed, so that the top block 14 of the material distribution will be retracted and the concrete in the tube mold 10 will continue to be squeezed, so as to ensure that after the concrete is fed into the tube mold 10, the phenomenon of concrete being thrown out is avoided.

[0033] During the continuous operation, excess concrete will adhere to the outer sides of the preloading tube 11 and the suspension roller shaft 4. When the preloading tube 11 passes through the scraper block 121, the concrete adhered to the preloading tube 11 will be scraped out by the scraper block 121, causing the excess concrete to be mixed and output again from the residual material channel 120 with the concrete output from the storage chamber 122. As for the concrete on the top cloth block 14, when the preloading tube 11 rotates, the top cloth block 14 will be continuously pressed back to the inside of the preloading tube 11 through the bottom of the storage box 12. After being pressed back, the top cloth block 14 will scrape out the concrete on the outer side of the top cloth block 14 through the scraper block 121, thereby scraping off the concrete adhered to the outer side of the top cloth block 14, thereby cleaning the preloading tube 11 and the outer side of the top cloth block 14. The concrete adhered to the outer side of the suspension roller shaft 4 is processed. As for the concrete adhered to the outer side of the suspension roller shaft 4, the suspension roller shaft 4 drives the driving tube 6 to rotate in the initial process to ensure that the driving tube 6 provides hydraulic pressure to the telescopic pipe 2 to realize the pre-stressing tube 11 to be pressed on the inner wall of the pipe mold 10. When the pressure on the pre-stressing tube 11 gradually increases, the load of the driving tube 6 rotation will gradually increase, causing the driving tube 6 and the connecting sleeve 9 to slide relative to each other during the transmission process. The sliding of the suspension roller shaft 4 causes the concrete on the outer side of the suspension roller shaft 4 to be scraped out by the driving tube 6 and fall into the storage chamber 122. After that, the storage chamber 122 will be output to the inner wall of the pipe mold 10 again, so that the concrete will not be wasted.

[0034] After the final completion, the suspension roller shaft 4 is rotated in the opposite direction, causing the driving pipe 6 to pump the hydraulic pressure in the telescopic pipe 2 back into the infusion pipe 8, and after the storage box 12 is lifted to the top, the medium in the infusion pipe 8 is blocked by the on-off valve 3, thereby preventing the pre-load pipe 11 from falling autonomously due to gravity after the driving pipe 6 stops. Then, the pipe mold 10 is lifted by the lifting tool, and then the frame 1 is moved out again, and the pipe mold 10 is lifted out by the lifting tool to complete the pipe making work.
