DETAILED DESCRIPTION

[0028] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0029] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0030] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 8As shown, it is a structural diagram of a continuous processing and forming equipment for cement pipe production provided by an embodiment of the present invention, comprising a workbench 1, a column 2 is rotatably mounted on the surface of the workbench 1, a carrying plate 3 is fixedly mounted on the surface of the column 2, the carrying plate 3 is a regular polygonal structure, the side wall of the carrying plate 3 is provided with a plurality of groups of forming cylinders 4 distributed in an annular shape with equal spacing, the two ends of the forming cylinder 4 are through-through, a material injection port 41 is opened on the surface of the forming cylinder 4, a plurality of groups of core columns 5 are fixedly mounted on the side wall of the carrying plate 3, respectively located in the inner cavity of the forming cylinder 4, the surface of the workbench 1 is fixedly mounted There is an arc-shaped sealing plate 6, which is fitted with one end of the forming cylinder 4 away from the carrier plate 3. The sealing plate 6 is provided with a notch. A positioning frame 10 is fixedly installed on the surface of the workbench 1. A hydraulic cylinder 11 is fixedly installed on the surface of the positioning frame 10. The telescopic end of the hydraulic cylinder 11 is fixedly installed with an injection pipe 12 that cooperates with the injection port 41. The injection pipe 12 is connected to the external grouting equipment through a conduit. A rotating mechanism 7 that cooperates with the carrier plate 3 is provided on the surface of the workbench 1. The rotating mechanism 7 includes an intermittent rotation component 71 and a limit component 72, the intermittent rotation component 71 is located on the surface of the workbench 1 and is connected to the column 2, the limiting component 72 is located on the bottom wall of the carrier plate 3, the limiting component 72 controls the column 2 and the carrier plate 3 to rotate intermittently by cooperating with the intermittent rotation component 71, the angle of rotation of the column 2 and the carrier plate 3 is 360 degrees, which is divided into an angle by the number of sides of the carrier plate 3. For example, when the carrier plate 3 is a hexagon, the certain angle is 60 degrees, and when the carrier plate 3 is a pentagon, the certain angle is 72 degrees. The surface of the carrier plate 3 is provided with a The tube unloading mechanism 8 includes a push ring 81, a positioning assembly 82 and a driving assembly 83. The positioning assembly 82 is located in the carrier plate 3 and is connected to the push ring 81. The positioning assembly 82 is used to control the push ring 81 to be located at the side wall of the carrier plate 3 and to control the push ring 81 to be sleeved on the outside of the core column 5. The driving assembly 83 is located in the carrier plate 3 and is connected to the positioning assembly 82. When the forming tube 4 rotates to the notch position facing the sealing plate 6, the driving assembly 83 controls the push ring 81 to move toward the inner cavity of the forming tube 4 by cooperating with the positioning assembly 82.

[0031] The column 2 supports and positions the carrier plate 3 on the surface of the workbench 1, and the carrier plate 3 supports and positions the multiple groups of molding cylinders 4. When in use, the intermittent rotation component 71 cooperates with the limit component 72 to control the column 2 to intermittently rotate a certain angle. The column 2 drives the carrier plate 3 and the multiple groups of molding cylinders 4 to rotate synchronously and intermittently at a certain angle. When the molding cylinder 4 rotates to just below the injection pipe 12, the sealing plate 6 seals the end of the molding cylinder 4 away from the carrier plate 3. The hydraulic cylinder 11 pushes the injection pipe 12 to move vertically downward. When the injection pipe 12 is inserted into the injection port 41, the external grouting equipment transports cement slurry into the molding cylinder 4 through the injection pipe 12. After the grouting is completed, the hydraulic cylinder 11 drives the injection pipe 12 to move vertically upward, and the column 2 drives the carrier plate 3 and the molding cylinder 4 to rotate a certain angle again. The sealing plate 6 can continuously seal the molding cylinder 4. During the continuous rotation of the forming cylinder 4 , the forming cylinder 4 and the core column 5 cooperate with each other to position the cement slurry, and the cement slurry solidifies in the forming cylinder 4 to form a cement pipe.

[0032] The positioning assembly 82 supports and positions the push ring 81 at the side wall of the carrier plate 3. When the carrier plate 3 drives the forming tube 4 to rotate to the notch position of the sealing plate 6, the sealing plate 6 releases the sealing restriction on the end of the forming tube 4, and the end of the forming tube 4 away from the carrier plate 3 switches to an open state. When the carrier plate 3 drives the forming tube 4 to rotate at the notch position of the sealing plate 6, the driving assembly 83 cooperates with the positioning assembly 82 to control the push ring 81 to move toward the inner cavity of the forming tube 4. When the push ring 81 moves toward the inner cavity of the forming tube 4, it applies a thrust to the cement pipe in the inner cavity of the forming tube 4. The push ring 81 can automatically push the cement pipe out of the forming tube 4. After one end of the cement pipe moves to the outside of the forming tube 4, the staff can easily pull the cement pipe out of the forming tube 4. After the cement pipe is pulled out, the positioning assembly 82 controls the push ring 81 to move back to its original position. After the forming tube 4 rotates again to directly below the injection pipe 12, the sealing plate 6 closes the end of the forming tube 4 again, and the grouting molding process can be performed on it again. This cycle is repeated to continuously shape the cement pipe, effectively improving the processing efficiency of the cement pipe.

[0033] like Figure 2 、 Figure 8 、 Figure 10 As shown, as a preferred embodiment of the present invention, the intermittent rotation component 71 includes a positioning gear disc 711 fixedly mounted on the surface of the column 2 and located below the supporting plate 3, and a first motor 712 is fixedly mounted on the bottom wall of the workbench 1. The output shaft of the first motor 712 extends to the surface of the workbench 1 and is fixedly mounted with a transmission disc 713. An arc-shaped transmission rack 714 is fixedly mounted on the surface of the transmission disc 713, and the transmission rack 714 is engaged with the positioning gear disc 711.

[0034] During operation, the first motor 712 rotates the transmission disc 713, which in turn rotates the transmission rack 714. When the transmission rack 714 rotates until it contacts the positioning gear disc 711, the transmission rack 714 engages with the positioning gear disc 711, driving the column 2 to rotate, which in turn drives the carrier disc 3 to rotate synchronously. When the transmission rack 714 and the positioning gear disc 711 separate, the transmission rack 714 releases the driving force on the positioning gear disc 711, and the limit assembly 72 controls the carrier disc 3 to stop rotating above the workbench 1. This cycle repeats, controlling the column 2 and the carrier disc 3 to intermittently rotate at a certain angle on the surface of the workbench 1.

[0035] like Figure 2 、 Figure 8 、 Figure 10 As shown, as a preferred embodiment of the present invention, the limiting assembly 72 includes a plurality of first magnetic blocks 721 fixedly mounted on the bottom wall of the carrier plate 3 and distributed in a circular shape with equal intervals, and a group of second magnetic blocks 722 that cooperate with the first magnetic blocks 721 are fixedly mounted on the surface of the workbench 1.

[0036] A set of first magnetic blocks 721 on the bottom wall of the carrier plate 3 and a second magnetic block 722 on the surface of the workbench 1 are connected to form a single unit through magnetic attraction. At this point, the carrier plate 3 remains stationary on the surface of the workbench 1. When the column 2 drives the carrier plate 3 to rotate, the carrier plate 3 drives the first magnetic blocks 721 to rotate synchronously. At this point, the first magnetic blocks 721 and the second magnetic blocks 722 separate from each other. When the transmission rack 714 releases the driving force on the positioning gear plate 711, the other set of first magnetic blocks 721 on the bottom wall of the carrier plate 3 once again adhere to the second magnetic block 722 to form a single unit. At this point, the carrier plate 3 remains stationary on the surface of the workbench 1.

[0037] like Figure 2 、 Figure 5 、 Figure 6 、 Figure 7 As shown, as a preferred embodiment of the present invention, the positioning assembly 82 includes multiple groups of annular receiving grooves 821 opened on the side wall of the supporting plate 3, the forming cylinder 4 is sleeved on the outside of the receiving groove 821, and the push ring 81 is placed in the receiving groove 821. Multiple groups of control chambers 822 relative to the receiving groove 821 are opened inside the supporting plate 3, and a slide 823 is slidably installed in the control chamber 822. Multiple groups of connecting rods 824 are fixedly installed on the side wall of the slide 823, and the connecting rod 824 extends from one end of the slide 823 to the receiving groove 821 and is fixedly connected to the push ring 81. A horizontal plate 825 is fixedly installed in the control chamber 822, and an extrusion spring 826 is fixedly installed on the side wall of the horizontal plate 825. The telescopic end of the extrusion spring 826 is connected to the slide 823.

[0038] The extrusion spring 826 applies a thrust to the slide plate 823, which is located at one end of the control chamber 822 away from the receiving groove 821. The slide plate 823 cooperates with the connecting rod 824 to support and position the push ring 81, and the push ring 81 is stably located in the receiving groove 821. When the cement slurry solidifies in the forming tube 4, the push ring 81 will not interfere with the solidification process of the cement slurry. When the supporting plate 3 drives the forming tube 4 to rotate at the notch of the sealing plate 6, the driving assembly 83 applies a pulling force to the slide plate 823, so that the slide plate 823 moves toward the receiving groove 821 in the control chamber 822. The slide plate 823 cooperates with the connecting rod 824 to push the push ring 81 toward the inner cavity of the forming tube 4. The push ring 81 applies a thrust to the cement pipe after the inner cavity of the forming tube 4 solidifies, and the cement pipe can be easily pushed to the outside of the forming tube 4. The carrier plate 3 drives the forming cylinder 4 to continue rotating, the driving assembly 83 releases the tension on the slide plate 823, and the extrusion spring 826 pushes the slide plate 823 to move back to its original position within the control chamber 822. At this time, the push ring 81 moves synchronously into the receiving groove 821. After the forming cylinder 4 rotates again to directly below the injection tube 12, the sealing plate 6 seals the end of the forming cylinder 4 again, and the grouting molding process can be carried out again.

[0039] like Figure 2 、 Figure 4 、 Figure 5 、 Figure 7 、 Figure 10 As shown, as a preferred embodiment of the present invention, the driving assembly 83 includes a cross bar 831 rotatably mounted on one end of the inner cavity of the control chamber 822 near the push ring 81, a winding disk 832 is fixedly mounted on the surface of the cross bar 831, a traction rope 833 is wound on the surface of the winding disk 832, and the end of the traction rope 833 away from the winding disk 832 passes through the cross plate 825 and is connected to the slide plate 823, a first rotating column 834 is rotatably mounted on the side wall of the control chamber 822, a driving bevel gear disc 836 is fixedly mounted on the surface of the first rotating column 834, a driven bevel gear disc 835 is fixedly mounted on the surface of the cross bar 831, and the driven bevel gear disc 835 is meshed and connected with the driving bevel gear disc 836 Next, the surface of the carrying disk 3 is downwardly provided with multiple groups of connecting grooves 837 connected to the control cavity 822, and a second rotating column 838 is rotatably installed in the connecting groove 837. The surfaces of the first rotating column 834 and the second rotating column 838 are respectively fixedly installed with synchronous gear discs 839, and the two groups of synchronous gear discs 839 are commonly connected to a synchronous belt 8310. The surface of the second rotating column 838 is fixedly installed with a control gear disc 8311 extending to the outside of the carrying disk 3, and the surface of the workbench 1 is fixedly installed with two groups of brackets 8312, and the two groups of brackets 8312 are commonly fixedly installed with a positioning rack 8313 located above the carrying disk 3, and the positioning rack 8313 is engaged with the control gear disc 8311.

[0040] When the carrier plate 3 rotates, it drives the control gear disc 8311 to rotate synchronously. When a group of forming cylinders 4 rotates at the notch of the sealing plate 6, the control gear disc 8311 on the surface of the carrier plate 3 contacts the positioning rack 8313, and the control gear disc 8311 rolls along the surface of the positioning rack 8313. The control gear disc 8311 drives the second rotating column 838 to rotate, and the second rotating column 838 drives the synchronous gear disc 839 to rotate. The two groups of synchronous gear discs 839 cooperate with the synchronous belt 8310 to rotate. The first rotating column 834 is driven to rotate within the control chamber 822, and the first rotating column 834 drives the active bevel gear plate 836 to rotate. The active bevel gear plate 836 meshes with the driven bevel gear plate 835 to drive the crossbar 831 to rotate. The crossbar 831 drives the winding disk 832 to rotate. The winding disk 832 winds the traction rope 833. When the traction rope 833 is wound, it exerts a pulling force on the slide 823, causing the slide 823 to move toward the receiving slot 821 within the control chamber 822. When the control gear plate 8311 and the positioning rack 8313 on the surface of the carrier plate 3 separate from each other, the crossbar 831 and the winding disk 832 release the winding of the traction rope 833, and the compression spring 826 pushes the slide 823 to move back to its original position within the control chamber 822.

[0041] like Figure 1 、 Figure 9 As shown, as a preferred embodiment of the present invention, the forming cylinder 4 is configured as two groups of half cylinders distributed relatively, and the two groups of half cylinders are slidably installed on the outside of the carrying plate 3. The side wall of the carrying plate 3 is provided with a demolding mechanism 9 that cooperates with the half cylinder, and the demolding mechanism 9 includes a support component 91 and a telescopic component 92. The support component 91 is located on the side wall of the carrying plate 3 and is connected to the half cylinder. The support component 91 is used to control the two groups of half cylinders to fit together into a whole. The telescopic component 92 is connected to the support component 91. The telescopic component 92 controls the two groups of half cylinders to move in opposite directions by cooperating with the support component 91.

[0042] The support assembly 91 supports and positions the two sets of half-tubes outside the carrier plate 3, allowing the two sets of half-tubes to fit together to form a single unit. When the forming tube 4 rotates within the notch of the sealing plate 6, the telescopic assembly 92 cooperates with the support assembly 91 to control the movement of the two sets of half-tubes in opposite directions. This allows the inner walls of the half-tubes to separate from the cement pipe, eliminating frictional resistance between the cement pipe and the inner walls of the half-tubes, allowing the push ring 81 to more easily push the cement pipe out from the outside of the core column 5.

[0043] like Figure 1 、 Figure 9As shown, as a preferred embodiment of the present invention, the support assembly 91 includes two groups of fixed plates 911 fixedly installed on the side walls of the supporting plate 3, which are respectively located on both sides of the two groups of half-cylinders, and a guide rod 912 is fixedly installed between the two groups of fixed plates 911. The half-cylinder is slidingly connected to the guide rod 912, and a return spring 913 is fixedly installed on the side wall of the fixed plate 911, and the telescopic end of the return spring 913 is connected to the half-cylinder.

[0044] The fixed plate 911 supports and positions the return spring 913, and the return spring 913 applies a thrust to the half-cylinder, so that the two groups of half-cylinders fit together and form a whole. The two groups of half-cylinders cooperate with the core column 5 to control the solidification of cement slurry to form a cement pipe. When the forming cylinder 4 rotates at the notch of the sealing plate 6, the telescopic component 92 pulls the half-cylinder toward the fixed plate 911. At this time, the inner wall of the half-cylinder and the surface of the cement pipe are separated from each other, which can eliminate the friction resistance between the cement pipe and the inner wall of the half-cylinder, and the push ring 81 can more easily push the cement pipe out from the outside of the core column 5. After the cement pipe is taken out, the telescopic component 92 releases the pulling force on the half-cylinder, and the return spring 913 pushes the half-cylinder to move back to its original position, making it easier to fill the cement slurry again.

[0045] like Figure 1 、 Figure 9 As shown, as a preferred embodiment of the present invention, the telescopic assembly 92 includes two groups of side plates 921 fixedly installed on a side wall of the fixed plate 911 away from the half cylinder, and the two groups of side plates 921 are installed with a winding roller 922 for rotation together, and one end of the winding roller 922 is connected to a second motor 923, and a pulling wire 924 is wound on the surface of the winding roller 922, and the end of the pulling wire 924 away from the winding roller 922 passes through the fixed plate 911 and is connected to the half cylinder.

[0046] When the forming cylinder 4 rotates at the notch of the sealing plate 6, the second motor 923 drives the winding roller 922 to rotate, and the winding roller 922 winds the pulling wire 924. The pulling wire 924 pulls the half cylinder toward the fixed plate 911 when winding. After the cement pipe is taken out, the second motor 923 controls the winding roller 922 to rotate in the opposite direction, and the return spring 913 pushes the half cylinder to move in the opposite direction to its original position, so as to facilitate the filling of cement slurry again.

[0047] The working principle of the present invention is as follows: the column 2 supports and positions the carrier plate 3 on the surface of the workbench 1, and the carrier plate 3 supports and positions multiple groups of molding cylinders 4. During use, the first motor 712 drives the transmission plate 713 to rotate, and the transmission plate 713 drives the transmission rack 714 to rotate. When the transmission rack 714 rotates to contact the positioning gear plate 711, the transmission rack 714 engages with the positioning gear plate 711 for transmission, which can drive the column 2 to rotate, and the column 2 drives the carrier plate 3 to rotate synchronously. When the transmission rack 714 and the positioning gear plate 711 separate from each other, the transmission rack 714 releases the driving force on the positioning gear plate 711, and the other group of first magnetic blocks 721 on the bottom wall of the carrier plate 3 are again attached to the second magnetic block 722 to form a whole. At this time, the carrier plate 3 remains stationary on the surface of the workbench 1 again.

[0048] The column 2 drives the supporting plate 3 and the multiple groups of forming cylinders 4 to rotate synchronously and intermittently by a certain angle. When the forming cylinder 4 rotates to the point directly below the injection tube 12, the sealing plate 6 seals the end of the forming cylinder 4 away from the supporting plate 3. The hydraulic cylinder 11 pushes the injection tube 12 to move vertically downward. After the injection tube 12 is inserted into the injection port 41, the external grouting equipment transports the cement slurry into the forming cylinder 4 through the injection tube 12. After the grouting is completed, the hydraulic cylinder 11 drives the injection tube 12 to move vertically upward, and the column 2 drives the supporting plate 3 and the forming cylinder 4 to rotate again by a certain angle. The sealing plate 6 can continuously seal the forming cylinder 4. During the continuous rotation of the forming cylinder 4, the forming cylinder 4 and the core column 5 cooperate with each other to position the cement slurry, and the cement slurry solidifies in the forming cylinder 4 to form a cement tube.

[0049] When the carrier plate 3 drives the forming cylinder 4 to rotate to the notch position of the sealing plate 6, the sealing plate 6 releases the sealing restriction on the end of the forming cylinder 4, and the end of the forming cylinder 4 away from the carrier plate 3 switches to an open state. When the carrying disc 3 drives the forming cylinder 4 to rotate at the notch of the sealing plate 6, the control gear disc 8311 on the surface of the carrying disc 3 contacts the positioning rack 8313, and the control gear disc 8311 rolls along the surface of the positioning rack 8313. The control gear disc 8311 drives the second rotating column 838 to rotate, and the second rotating column 838 drives the synchronous gear disc 839 to rotate. The two sets of synchronous gear discs 839 cooperate with the synchronous belt 8310 to drive the first rotating column 834 to rotate in the control cavity 822. The first rotating column 834 drives the active bevel gear disc 836 to rotate, and the active bevel gear disc 836 and the driven bevel gear disc 835 engage and transmit, which can drive the cross bar 831 to rotate, and the cross bar 831 drives the winding disk 832 to rotate, and the winding disk 832 reels the traction rope 833. The traction rope 833 applies tension to the slide plate 823 when reeling, and the slide plate 823 moves toward the receiving groove 821 in the control cavity 822. The slide plate 823 cooperates with the connecting rod 824 to push the push ring 81 toward the inner cavity of the forming cylinder 4. The push ring 81 applies thrust to the cement pipe after solidification in the inner cavity of the forming cylinder 4, which can conveniently push the cement pipe to the outside of the forming cylinder 4. The supporting disc 3 drives the forming cylinder 4 to rotate continuously. The control gear disc 8311 and the positioning rack 8313 on the surface of the supporting disc 3 separate from each other, the cross bar 831 and the winding disc 832 release the winding of the traction rope 833, and the extrusion spring 826 pushes the slide plate 823 to move back to its original position in the control cavity 822.

[0050] The preferred embodiments of the present invention are described in detail above, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in this field without departing from the purpose of the present invention.
