[0018] Description of Reference Numerals DETAILED DESCRIPTION

[0019] The following describes the specific embodiments of the present application in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not intended to limit the present application.

[0020] The following describes the pipe pile injection system and control method according to the present application with reference to the accompanying drawings.

[0021] like Figure 1 and Figure 2 As shown, the present application proposes a pipe pile pouring system, including a pipe pile pump 10, a delivery pipe, a movable mold vehicle 30, a detection component and a control unit 40; the pipe pile pump 10 is used to pump concrete; the delivery pipe includes a main line 21 and at least two branch lines 22 connected to the main line 21, the inlet end of the main line 21 is connected to the pipe pile pump 10, and the outlet end of the main line 21 is connected to the inlet end of each branch line 22; the outlet end of each branch line 22 can be used to connect a movable mold vehicle 30, the movable mold vehicle 30 is provided with a pipe pile mold, the pipe pile mold is used to receive concrete delivered from the branch line 22, and the movable mold vehicle 30 can be detached from the branch line 22 and moved to a centrifugal position for centrifugal shaping; the detection component is provided on the branch line 22; the control unit 40 is electrically connected to the detection component, and the control unit 40 is used to control the multiple branch lines 22 to be alternately turned on and off according to the detection signal of the detection component, so that the multiple movable mold vehicles 30 alternately pour concrete.

[0022] Among them, the pipe pile pump 10 is used to pump concrete into the main pipeline 21 of the delivery pipe and transport it to the corresponding branch pipeline 22 as needed. The movable mold vehicle 30 can be matched with the outlet end of the corresponding branch pipeline 22, and the concrete can be transported to the corresponding pipe pile mold through the branch pipeline 22; when the pipe pile mold of the movable mold vehicle 30 is filled with concrete, the pipe pile mold on the movable mold vehicle 30 is transferred to a centrifugal position for centrifugal shaping. In this embodiment, by setting a detection component on the branch pipeline 22, the control unit 40 can determine whether the outlet end of the branch pipeline 22 is connected to the movable mold vehicle 30 based on the detection signal of the detection component, and then alternately control the opening and closing of multiple branch pipelines 22 according to the situation. In this way, one pipe pile pump 10 can simultaneously control the alternating pouring of multiple pipe pile molds, saving space and cost of the pipe pile pump 10, while improving the efficiency of pipe pile production. At the same time, the unmanned control method of the pouring system reduces manpower.

[0023] Furthermore, the pile pump 10 can be of various types, such as piston concrete pumps, screw concrete pumps, and gear pumps, all of which are within the scope of protection of this application. When the pile pump 10 rotates forward, its pumping unit pumps concrete out of its discharge port at high pressure, thereby delivering concrete to the delivery pipe. Since the main line 21 connects to the two branch lines 22, the concrete delivery path is divided into two. When the pile pump 10 rotates backward, concrete remaining in the delivery pipe can be sucked back into the pile pump 10.

[0024] Moreover, since the movable mold cart 30 is used instead of the production line transportation, it is flexible and independent, the two pouring lines can produce independently, and problems with a single pipe pile mold will not affect the operation of the production line. Moreover, the pipe pile mold can be separated from the movable mold cart 30, which is more convenient to clean.

[0025] In some embodiments, the detection component includes a position sensor 61 and an on-off valve; each branch pipeline 22 is provided with a position sensor 61, and the position sensor 61 is used to detect whether the outlet end of the branch pipeline 22 is connected to the movable mold vehicle 30; the control unit 40 is used to control the on-off of the on-off valve according to the sensing signal of the position sensor 61, so that multiple branch pipelines 22 are alternately on and off.

[0026] In this embodiment, each position sensor 61 is used to detect whether the outlet end of the corresponding branch pipeline 22 is connected to the movable mold vehicle 30. When the branch pipeline 22 is connected to the movable mold vehicle 30, a sensing signal is sent, and the control unit 40 controls the branch pipelines 22 connected to the movable mold vehicle 30 to be alternately connected, and the concrete of the pile pump 10 is pumped into the pile mold of the movable mold vehicle 30. The present application realizes the automatic control on and off of each branch pipeline 22 through the linkage of the position sensor 61, the on-off valve and the control unit 40. The pile pump 10 continues to work, and multiple branch pipelines 22 alternately transport concrete. This can reduce the waiting time of concrete in the delivery pipe, reduce concrete segregation, and reduce the risk of concrete blockage.

[0027] In some embodiments, the position sensor 61 is disposed near the outlet end of the branch pipe 22 . The position sensor 61 is one of a paddle sensor, a proximity switch, or a displacement sensor.

[0028] like Figure 1 As shown, each branch pipeline 22 is equipped with a paddle sensor. This paddle sensor is a non-contact proximity switch used to detect material flow, position, or equipment operating status. Its core function is to sense the movement of a metal paddle, triggering a sensing signal that is transmitted to the control unit 40, enabling the control unit 40 to control the opening and closing of the corresponding on-off valve. When the outlet of the branch pipeline 22 is connected to the movable mold cart 30, the movable mold cart 30 pushes the metal paddle of the paddle sensor, generating a sensing signal. Based on this sensing signal, the control unit 40 can determine whether the outlet of the branch pipeline 22 is connected to the movable mold cart 30.

[0029] Among them, the on-off valve can have the following two structural forms: like Figure 1 As shown, in the first embodiment, the main pipeline 21 and the plurality of branch pipelines 22 are connected via a multi-way pipe 23. For example, when there are two branch pipelines 22, the multi-way pipe 23 is a tee, one port of which is connected to the main pipeline 21, and the other two ports are connected to the two branch pipelines 22. The on-off valve is an electric stop valve 62, which is provided on the branch pipeline 22 and located between the position sensor 61 and the inlet end of the branch pipeline 22. In this embodiment, the electric stop valve 62 is electrically connected to the control unit 40, and the control unit 40 can directly control the on-off of the electric stop valve 62. The on-off of the electric stop valve 62 controls the connection or blocking of the corresponding branch pipeline 22. In this way, the concrete in the main pipeline 21 can be switched to flow to different branch pipelines 22, so that the concrete of a pile pump 10 can be switched to flow to different pile molds by switching the electric stop valve 62.

[0030] Specifically, during the pouring process, when the movable mold trolley 30 is matched and connected with the branch pipeline 22, the paddle sensor on the corresponding branch pipeline 22 senses a signal and transmits it to the control unit 40. The control unit 40 outputs a signal to the electric stop valve 62 to adjust the on-off of the concrete flow channel to ensure that the flow channel connecting the branch pipeline 22 and the movable mold trolley 30 is unobstructed. After the electric stop valve 62 has reached its stroke, the control unit 40 outputs a signal to the pile pump 10 to pump concrete. The concrete is filled into the pile mold on the movable mold trolley 30 through the concrete delivery pipe. After filling, the control unit 40 outputs a signal to the pile pump 10 to stop pumping. At the same time, the movable mold trolley 30 is separated from the concrete delivery pipe, and the pile mold is transferred to the automatic centrifugal device 50. Then the external manipulator grabs another pile mold and puts it on the movable mold trolley 30 to wait for pouring.

[0031] like Figure 2 As shown, the on-off valve is an electric multi-way valve 63, which is connected between the main line 21 and the branch line 22. The inlet end of the electric multi-way valve 63 is connected to the outlet end of the main line 21, and each outlet end of the electric multi-way valve 63 is connected to each branch line 22 one by one.

[0032] The number of branch channels of the electric multi-way valve 63 and the number of branch pipelines 22 are the same. Figure 2 As shown, the electric multi-way valve 63 is a three-way valve, with its two branch channels connected to the two branch pipelines 22. The electric multi-way valve 63 is a valve device that can control the flow direction of concrete via the control unit 40. Compared to a one-way valve, it can achieve multiple switching without downtime, significantly improving production efficiency. In this embodiment, a single pile pump 10 is used to simultaneously service two pile molds through the three-way valve, reducing equipment idleness and saving pile pouring costs.

[0033] In some embodiments, the pipe pile pouring system further includes a centrifugal device 50 . The movable mold vehicle 30 can move between the branch pipeline 22 and the centrifugal device 50 . The centrifugal device 50 can receive the pipe pile molds poured with concrete and perform centrifugal shaping.

[0034] Among them, the centrifugal device 50 has the structure of a centrifugal device 50 commonly used in pipe pile casting systems in the prior art. The centrifugal device 50 includes a centrifuge main unit, a pipe mold and a feeding structure. During centrifugation, the pipe pile mold filled with concrete is fed into the rotating pipe mold through the feeding structure. The centrifugal force of the centrifuge main unit evenly distributes the concrete mixture on the inner wall of the pipe mold. The centrifugal force squeezes the concrete and discharges bubbles and excess water to form a highly dense concrete layer, thereby realizing the "inside-middle-outside" three-layer structure of the pipe pile mold (mortar layer, middle concrete layer, and pure slurry layer).

[0035] A second aspect of the present application provides a pipe pile pouring control method, which is applied to the pipe pile pouring system described above. The pipe pile pouring control method comprises the following steps: Obtaining a detection signal from a detection component; When a detection signal is received, determining the detection type of the detection signal of each branch pipeline 22; Controlling the corresponding branch pipeline 22 to communicate and transport concrete according to the detection type of each branch pipeline 22; When the pipe pile mold on the movable mold vehicle 30 is filled, the corresponding branch pipeline 22 is controlled to be disconnected, and the movable mold vehicle 30 is separated from the branch pipeline 22 and the pipe pile mold is centrifugally shaped.

[0036] In this embodiment, when pouring pipe piles, the detection signal of the detection component is first obtained. When the detection signal is received, it indicates that the branch pipeline 22 has been connected to the movable mold vehicle 30. Then, the detection type of the detection signal of each branch pipeline 22 is judged, so that it can be determined which branch pipeline 22 is used to transport concrete according to the detection type. During transportation, one branch pipeline 22 can be controlled to be connected and transport concrete to the connected movable mold vehicle 30. When the pipe pile mold is full, the corresponding branch pipeline 22 is controlled to be disconnected, and then the pipe pile mold is centrifugally shaped. Then, the above steps are repeated to alternately pour multiple pipe pile molds. The present application saves space and cost of the pipe pile pump 10 by simultaneously controlling the alternate pouring of multiple pipe pile molds through a pipe pile pump 10, while improving the production efficiency of pipe piles.

[0037] In some embodiments, the step of controlling the corresponding branch pipeline 22 to pump concrete according to the detection type of the detection signal of each branch pipeline 22 includes: When one of the position sensors 61 is closed and the other position sensors 61 are disconnected, the branch pipe 22 where the closed position sensor 61 is located is controlled to be connected and concrete is pumped; When multiple position sensors 61 are closed, keep one movable mold vehicle 30 connected to the branch pipeline 22, control the other movable mold vehicles 30 to disconnect from the branch pipeline 22, and control the branch pipeline 22 where the closed position sensor 61 is located to be connected and pump concrete.

[0038] Specifically, when there are two branch pipes 22 and the position sensor 61 is a paddle sensor, as shown in FIG. Figure 3As shown, when the perfusion system begins operation, it first checks whether the paddle sensors at the outlet ends of the two branch pipelines 22 detect signals. If the control unit 40 receives a sensing signal from the paddle sensor, it indicates that at least one branch pipeline 22 is now connected to the movable mold cart 30. The paddle sensor signal type detection then begins, detecting whether both paddle sensors A2 and B2 have signals. If both paddle sensors A2 and B2 have signals, it indicates that both branch pipelines 22 are connected to the movable mold cart 30. The movable mold cart B3 is then controlled to disconnect from the corresponding branch pipeline 22. The paddle sensor signals are then checked to see whether A2 is open and B2 is closed, ensuring that only one movable mold cart 30 is connected to the branch pipeline 22. The other movable mold carts 30 are disconnected from the branch pipeline 22 first. When the paddle sensor detects that A2 is open and B2 is closed, the control unit 40 controls the electric stop valve A1 to open and B1 to close. Once the electric stop valve 62 has reached its full travel, the control unit 40 controls the pile pump 10 to begin pumping concrete. Concrete is then injected into the pile mold connected to the corresponding branch line 22 through the delivery pipe. When the pile mold is full, the control unit 40 outputs a pumping stop signal. After stopping pumping, the control unit 40 controls the movable mold vehicle A3 to disconnect from the branch line 22. After disconnection, the concrete-filled pile mold is transferred to the centrifugal device 50 for centrifugal shaping.

[0039] If further pouring is required, the movable mold cart B3 is controlled to mate and dock with the delivery pipe. After docking, the paddle sensor signal is detected. If the signal is A2 off and B2 open, the control unit 40 controls the electric stop valve A1 to close and B1 to open. After the electric stop valve 62 has reached its stroke, the control unit 40 controls the pile pump 10 to begin pumping concrete. Concrete is injected into the pile mold through the delivery pipe. When the pile mold is full, the control unit 40 outputs a pumping stop signal. After stopping pumping, the control unit 40 controls the movable mold cart B3 to disconnect from the branch pipe 22. After disconnection, the pile mold is sent to the centrifugal device 50 for centrifugal shaping. When further pouring is required, the above pouring process is repeated.

[0040] In this embodiment, by using one pipe pile pump 10 to simultaneously control two sets of pipe pile injection systems, costs are saved, the pipe pile injection is made more intelligent, and the production efficiency is improved.

[0041] In some embodiments, the pipe pile pouring control method further comprises the steps of: When the movable mold vehicle 30 is disconnected from the branch pipeline 22, the pile pump 10 is controlled to reverse and the concrete in the delivery pipe is sucked into the hopper; Another movable mold carriage 30 is controlled to be connected to the branch pipeline 22 .

[0042] In this embodiment, when the pile molds on the movable mold vehicle 30 are filled with concrete, the control unit 40 controls the movable mold vehicle 30 to disconnect from the branch pipeline 22. Simultaneously, the pile pump 10 activates reverse pumping to draw the remaining concrete in the delivery pipe into the hopper. This prevents the remaining concrete in the delivery pipe from segregating and reduces the risk of pipe blockage. When further pouring is required, another movable mold vehicle 30 is controlled to mate with the corresponding branch pipeline 22 to continue the pouring operation.

[0043] In some embodiments, after the movable mold vehicle 30 is separated from the branch pipeline 22 and before the step of centrifugally shaping the pile mold, the following steps are further included: Obtaining the on / off status of each position sensor 61; When the plurality of position sensors 61 are disconnected, the movable mold vehicle 30 sends the pipe pile mold into the centrifugal device 50 for centrifugal shaping.

[0044] In this embodiment, after the movable mold cart 30 is disconnected from the branch pipeline 22, it is necessary to determine whether the position sensor 61 has been disconnected. When the position sensor 61 is disconnected, it indicates that the movable mold cart 30 is completely disconnected from the branch pipeline 22. At this time, the movable mold cart 30 can be moved to the position of the centrifugal device 50 to feed the pipe pile mold into the centrifugal device 50 for centrifugal shaping. The present application determines whether the movable mold cart 30 is disconnected from the branch pipeline 22 by the on / off status of the position sensor 61, making the movement of the movable mold cart 30 more precise and preventing the movable mold cart 30 from not being completely disconnected from the branch pipeline 22 and affecting the subsequent centrifugation process.

[0045] In some embodiments, the pipe pile pouring control method further comprises the steps of: In the case that no detection signal is received, the movable mold vehicle 30 is controlled to be connected to the outlet end of one of the branch pipelines 22 .

[0046] In this embodiment, when the control unit 40 does not receive the sensing signal sent by the position sensor 61, it means that the outlet ends of the two branch pipelines 22 are not connected to the movable mold vehicle 30 at this time. If pouring needs to continue, the movable mold vehicle 30 can be controlled to carry the pipe pile module to match and dock with one of the branch pipelines 22. After the docking is completed, the signal type of the paddle sensor on each branch pipeline 22 (the on-off status of the paddle sensor) is obtained to perform the concrete pouring action.
