Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a wall forming system and a forming method thereof. BACKGROUND

[0002] In the field of building construction, the wall forming system as a key equipment for efficiently constructing wall structure is widely used in various types of construction projects. The working principle thereof is mainly to continuously convey the pre-mixed slurry to the forming mold through the pumping mechanism, and then form the required wall structure after solidification.

[0003] At present, the existing wall forming system generally has a significant technical limitation, that is, it is necessary to maintain the continuous slurry output state. This is because the structural design of the key components such as the conveying pipeline and the pumping assembly in the system has a high dependence on the fluidity and continuity of the slurry. Once the work is suspended due to construction needs (such as mold replacement, equipment maintenance, material supply, etc.), the slurry flow in the conveying pipeline and the pumping mechanism will stop immediately. Since the slurry itself has a certain viscosity and will quickly undergo initial setting or thickening in a stationary state, it is easy to deposit and bond at the inner wall of the pipeline, the valve interface, the pump body cavity and other parts. With the passage of time, these deposited slurry will gradually harden, causing the conveying pipeline to be blocked, and in severe cases, even causing the entire pumping mechanism to be stuck and damaged, that is, the machine is blocked.

[0004] Pipe blockage and machine blockage not only seriously affect the construction progress and cause the delay of the construction period, but also require a large amount of manpower and material resources for cleaning and maintenance, increasing the construction cost. In addition, frequent pipe blockage and machine blockage can cause permanent damage to the equipment, shorten the service life of the equipment, and bring many inconveniences and economic losses to the building construction.

[0050] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0051] like Figures 1-5As shown, this embodiment of the invention provides a wall forming system, including a slurry preparation module 1, a pump body 2, a pouring head 3, and a forming module 4. The slurry preparation module 1 is used to prepare wall forming slurry, the pump body 2 is used to pump the slurry prepared by the slurry preparation module 1, and a first pipe 5 is connected between the pump body 2 and the pouring head 3 for transporting the slurry to the pouring head 3. The pouring head 3 pours the slurry into the forming module 4 for wall forming. The pouring head 3 is equipped with a distance sensor (the distance sensor includes an ultrasonic distance sensor, a laser displacement sensor, etc. There are various embodiments of distance sensors in the prior art. The selection of the distance sensor is not the technical point of this invention, and the specific structure of the distance sensor will not be described here). When the wall extends into the sensing range of the pouring head 3, the pouring head 3 stops pouring slurry into the forming module 4.

[0052] Specifically, the pulping module 1 includes a material tank 11, a liquid tank 12, and a hollow mixing tank 13. The mixing tank 13 is used to thoroughly mix the materials and liquid. There are multiple material tanks 11, each storing different raw materials for producing the pulp (raw materials include limestone, clay, etc.). The liquid tank 12 stores water. Both the material tanks 11 and the liquid tank 12 are located on top of the mixing tank 13 and flow through it. A first valve is provided at the bottom of the material tank 11, and a second valve is provided at the bottom of the liquid tank 12. The mixing tank 13 contains a rotatable mixing disc 132 and a drive mixing disc 13. The first motor rotates, and multiple stirring teeth are arranged around the stirring disc 132. When the raw material for slurry enters the stirring tank 13, the stirring teeth will come into direct contact with the flowing raw material. The edges and protrusions of the stirring teeth will form a shearing force on the material, which can effectively break up the lumps or agglomerates of the material and improve the dispersion uniformity, thereby producing slurry. The top of the stirring tank 13 is provided with a vent 131 for ventilation and a liquid level sensor 133 for monitoring the liquid level height of the slurry inside the stirring tank. The bottom of the stirring tank 13 is formed with a discharge port 134 that flows into the interior of the stirring tank 13 and is connected to the water inlet of the pump body 2.

[0053] One end of the pouring head 3 is provided with a connecting seat 31 that can be detachably connected to the first driving mechanism (the first driving mechanism includes a robotic arm, a robotic hand, etc.). The first driving mechanism is used to move the position of the pouring head 3. A channel 32 is formed inside the pouring head 3. The inlet 321 and the first outlet 322 of the channel 32 are located at the top of the pouring head 3. The second outlet 323 of the channel 32 is located at the bottom of the pouring head 3. The inlet 321 is connected to the outlet of the pump body 2 through the first pipe 5.

[0054] A liquid sensor 51 is installed on the first pipe 5. The liquid sensor 51 is used to detect the slurry concentration at the location of the liquid sensor 51 inside the first pipe (there are many embodiments of liquid sensors in the prior art, including conductivity type concentration sensors, refractive index type concentration sensors, etc. There are many embodiments of objects sensed by liquid sensors in the prior art. The selection of liquid sensor is not the technical point of this invention, and the specific structure of liquid sensor will not be described in detail here). The first outlet 322 is connected to the outside, and the second outlet 323 is used to discharge slurry. A baffle 33 is rotatably installed inside the channel 32. A second motor is also installed on the pouring head 3 to drive the baffle 33 to rotate, so that the baffle 33 forms a first working position and a second working position inside the channel 32. When the baffle 33 is rotated to the vertical position, the baffle 33 is located in the first working position, and the inlet 321 and the second outlet 323 are connected; when the baffle 33 is rotated to the horizontal position, the baffle 33 is located in the second working position, and the inlet 321 and the first outlet 322 are connected.

[0055] The molding module 4 includes a connecting frame 41 and two belt molding mechanisms 42 symmetrically arranged on the connecting frame 41. The connecting frame 41 is detachably connected to an external second drive mechanism (the second drive mechanism includes a robotic arm, robotic hand, etc.). The second drive mechanism is used to move the position of the connecting frame 41. The belt molding mechanism 42 includes a molding belt 422 and multiple longitudinally arranged rollers 421 that drive the molding belt 422. The molding belt 422 is supported on both sides of the wall to be molded, serving as a mold cavity for slurry injection. The rollers 421 can provide support for the molding belt 422, helping it to fit against the wall. During the wall pouring process, the rollers 421 can drive the belt 422 to move, so that the molding belt 422 remains in contact with the wall during the longitudinal movement of the belt molding mechanism 42 and avoids sliding friction between the molding belt 422 and the wall surface, thereby reducing the impact on the wall.

[0056] A wall forming method, utilizing the aforementioned wall forming system, specifically includes the following steps:

[0057] S1. Connect the connecting frame 41 to the external second drive mechanism to move the molding module 4 to the position where the wall needs to be molded. Connect the connecting seat 31 to the external first drive mechanism so that the first drive mechanism moves the pouring head 3 above the molding module 4.

[0058] S2. Open the first valve at the bottom of the material tank 11 and the second valve at the bottom of the liquid tank 12. The baffle in the pouring head 3 rotates to the first working position. The material and liquid enter the mixing tank 13 and are mixed evenly. Then start the pump body 2. The slurry is pumped out by the pump body 2 and enters the pouring head 3 through the second pipe 6. The slurry flows out from the second outlet 323 and enters the mold cavity.

[0059] S3. The forming module 4 continues to move, causing the wall to continue to form and extend until the top of the wall enters the sensing range of the distance sensor on the pouring head 3. Then, the first valve at the bottom of the material bucket 11 is closed, and the wall forming continues using the residual slurry in the first pipe 5.

[0060] S4. When the liquid sensor 51 detects that the concentration has dropped to the set value (the set value refers to the concentration value that the slurry cannot reach the initial setting condition, determined according to the on-site environmental conditions), the baffle 33 rotates, moving the baffle 33 from the first working position to the second working position, connecting the inlet 321 and the first outlet 322, and the pump body 2 continues to work. The diluted slurry in the first pipe 5 is pumped out of the first pipe 5, and the pump body 2 automatically shuts off after the set working time.

[0061] S5. Move the molding module 4 to the new position of the wall to be molded. The molding module 4 completes the formwork support action at the new position, and the pouring head 3 moves to the top of the molding module 4 accordingly.

[0062] S6. Repeat steps S2-S5 above, continuously building walls without stopping the machine or cleaning the machine, until all the walls that need to be formed are completed.

[0063] In an improved embodiment, in order to recycle the diluted slurry within the first conduit 5, step S4 is as follows:

[0064] When the liquid sensor 51 detects that the concentration has dropped to the set value, the baffle 33 rotates, moving the baffle 33 from the first working position to the second working position, connecting the inlet 321 and the first outlet 322, and the pump body 2 starts to work in reverse, drawing the diluted slurry in the first pipe 5 into the mixing plate 3 (at this time, the consistency of the diluted slurry in the first pipe 5 decreases, and the slurry has not reached the initial setting condition). When the liquid level sensor 133 is triggered (i.e., the liquid level is too high), the pump body 2 is turned off.

[0065] like Figures 6-7 As shown, in an improved embodiment, the wall forming system further includes a second pipe 6, and a return port 135 is provided on the mixing plate 13. The second pipe 6 connects the first outlet 322 of the pouring head 3 and the return port 135.

[0066] In the wall forming method corresponding to this embodiment, step S4 is:

[0067] When the liquid sensor 51 detects that the concentration has dropped to the set value, the baffle 33 rotates, moving the baffle 33 from the first working position to the second working position, connecting the inlet 321 and the first outlet 322, and the pump body 2 continues to work. The diluted slurry in the first pipe 5 is pumped back into the mixing plate 3 through the second pipe 6, and the pump body 2 automatically shuts off after the set working time.

[0068] like Figure 8As shown, in a further improved embodiment, a third pipe 7 is also connected between the first pipe 5 and the second pipe 6. The connection between the third pipe 7 and the first pipe 5 is located between the liquid sensor 51 and the pump body 2. A first switching valve 73 affecting the connection between the third pipe 7 and the first pipe 5 is provided at the connection between the third pipe 7 and the first pipe 5. A piston 72 is provided on the third pipe 7 near the first pipe 5, and a cleaning ball 71 is placed at the end of the piston 72. A first sensor 731 for sensing the cleaning ball 71 is also provided on the first switching valve 73. The first pipe 5 is located near the connection between the third pipe 7 and the first pipe 5. A first check structure is provided at the location to prevent the cleaning ball from entering the pump body 2 along the first pipe (the check structure can be a check valve or a connecting pipe with an inner diameter smaller than the diameter of the cleaning ball installed at the pipe); a second switch valve 74 is provided at the connection between the third pipe 7 and the second pipe 6 to affect the connection between the third pipe 7 and the second pipe 6, and a second sensor 741 for sensing the cleaning ball 71 is also provided on the second switch valve 74; a second check structure is provided on the second pipe 6 near the connection between the third pipe 7 and the second pipe 6 to prevent the cleaning ball 71 from entering the return slurry port 135.

[0069] In the wall forming method corresponding to this embodiment, step S4 is:

[0070] When the liquid sensor 51 detects that the concentration has dropped to the set value, the baffle 33 rotates, moving from the first working position to the second working position. The inlet 321 and the first outlet 322 are connected, the first switch valve 73 opens, and the piston 72 drives the cleaning ball 71 into the first pipe 5. The pump body 2 continues to work, so that the diluted slurry in the first pipe 5 is pumped back into the mixing plate 3 through the second pipe 6, and the cleaning ball 71 moves along the first pipe 5 until it reaches the second switch valve 74. After the second sensor 741 senses the cleaning ball 71, it drives the second switch valve 74 to open, and the cleaning ball 71 enters the third pipe 7. After the cleaning ball 71 is sensed by the first sensor 731, the first switch valve 73 closes, the cleaning ball resets, and the pump body 2 is shut down.

[0071] In this embodiment, by introducing cleaning balls 71, the cleaning balls can clean the first pipe 5, the pouring head 3 and the second pipe 6 during the process of the diluted slurry being pumped back to the mixing plate 13.

[0072] like Figure 9 As shown, in a further improved embodiment, an air pump 8 is installed at the outlet of the pump body 2, the air pump 8 being used to pump high-pressure gas into the first pipeline 5.

[0073] In the wall forming method corresponding to this embodiment, step S4 is:

[0074] When the liquid sensor 51 detects that the concentration has dropped to the set value, the baffle 33 rotates, moving from the first working position to the second working position. The inlet 321 and the first outlet 322 are connected, the first switch valve 73 opens, the piston 72 drives the cleaning ball 71 into the first pipe 5, the pump body 2 and the second valve at the bottom of the liquid tank 12 are closed, and the air pump 8 is started, so that the diluted slurry in the first pipe 5 is pumped back into the mixing plate 3 through the second pipe 6, and the cleaning ball 71 moves along the first pipe 5 until it reaches the second switch valve 74. After the second sensor 741 senses the cleaning ball 71, it drives the second switch valve 74 to open, and the cleaning ball 71 enters the third pipe 7. After the cleaning ball 71 is sensed by the first sensor 731, the first switch valve 73 closes, the cleaning ball resets, and the air pump 8 is turned off.

[0075] like Figure 10 As shown, considering that the solidification of the slurry may be accelerated when the slurry is diluted by a high-pressure gas pump, in a further improved embodiment, a temporary storage chamber 9 is installed at the slurry return port 135. The temporary storage chamber 9 is equipped with a stirrer. The diluted slurry pumped back by the air pump 8 is temporarily stored in the temporary storage chamber 9, and the diluted slurry is mixed evenly before being sent back to the mixing tank 13.

[0076] In the wall forming method corresponding to this embodiment, step S4 is:

[0077] When the liquid sensor 51 detects that the concentration has dropped to the set value, the baffle 33 rotates, moving from the first working position to the second working position. The inlet 321 and the first outlet 322 are connected, the first switch valve 73 opens, the piston 72 drives the cleaning ball 71 into the first pipe 5, the pump body 2 and the second valve at the bottom of the liquid tank 12 are closed, and the air pump 8 is started, so that the diluted slurry in the first pipe 5 is pumped back to the temporary storage chamber 9 through the second pipe 6, and the cleaning ball 71 moves along the first pipe 5 until it reaches the second switch valve 74. After the second sensor 741 senses the cleaning ball 71, it drives the second switch valve 74 to open, and the cleaning ball 71 enters the third pipe 7. After the cleaning ball 71 is sensed by the first sensor 731, the first switch valve 73 closes, the cleaning ball resets, and the air pump 8 is turned off.

[0078] The wall forming system and its wall forming method, by setting up a pouring head 3 with two outlets, allows the slurry in the first pipe 5 to be pumped out of the first pipe 5 after the wall forming process is completed, thereby avoiding blockage of the first pipe 5.

[0079] The embodiments described above merely illustrate implementation methods of the present invention and should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
