Description

Technical Field

[0001] The present invention relates to the technical field of precast panel forming, and particularly relates to a forming device for assembled precast wall panels. Background Art

[0002] In the production process of assembled precast wall panels, the forming quality of concrete affects the subsequent construction safety and quality. At present, when precast wall panels are formed, air is often mixed into the concrete during the pouring process, generating bubbles. If these bubbles cannot be effectively discharged, it will cause hollowing phenomena after the concrete is formed, which may affect the structural strength and quality stability of the precast wall panels.

[0003] The existing treatment methods mainly rely on manual vibration or simple mechanical vibration to assist in exhausting air. Manual air exhaust may not effectively detect the residual situation of air bubbles inside the concrete, and the air exhaust effect is limited, unable to effectively eliminate the impact of bubbles on the quality of precast wall panels. Moreover, the existing devices also lack an effective cleaning mechanism for the detection components, resulting in impurities easily adhering to the surface of the detection components, affecting the detection accuracy, and further affecting the bubble detection and elimination effects. Summary of the Invention

[0004] The purpose of the present invention is to solve the problems raised in the above background art, and to propose a forming device for assembled precast wall panels.

[0005] To achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A forming device for assembled precast wall panels, including a mold detachably connected to a bottom plate, and further including:

[0007] A support frame, fixedly connected to the bottom plate;

[0008] A mounting plate, connected to the support frame, and the mounting plate is located directly above the mold;

[0009] Multiple groups of resistance sensors, fixedly connected to the mounting plate;

[0010] A first driving cylinder, fixedly connected to the side wall of the support frame, a first driving rod is slidably connected to the first driving cylinder, and a knocking plate is fixedly connected to the first driving rod;

[0011] The mounting plate drives the resistance sensors to move downward and insert into the concrete in the mold. When the resistance sensors encounter the obstruction of air bubbles in the concrete, the resistance sensors sense a decrease in resistance, and the first driving rod pushes the knocking plate to strike the side wall of the mold.

[0012] Preferably, a pressure storage chamber and a driving chamber are formed in the first driving cylinder. The pressure storage chamber is communicated with the driving chamber through a connecting pipe. A first sliding plug is slidably connected in the driving chamber, and the first sliding plug is fixedly connected to the first driving rod.

[0013] Further, a second driving cylinder is fixedly connected to the support frame. A second sliding plug is slidably connected in the second driving cylinder. A second driving rod is fixedly connected to the second sliding plug. One end of the second driving rod away from the second sliding plug is fixedly connected to the mounting plate. A first air pipe is fixedly connected to the second driving cylinder. One end of the first air pipe away from the second driving cylinder is communicated with the pressure storage chamber.

[0014] Further, a second air pipe is fixedly connected to the side wall of the first driving cylinder. An air chamber is formed in the mounting plate. One end of the second air pipe is communicated with the driving chamber, and the other end of the second air pipe is communicated with the air chamber. A jet pipe is fixedly connected to the bottom of the mounting plate. The air outlet ends of multiple groups of the jet pipes face the resistance sensor.

[0015] Further, a first spring is fixedly connected to the first sliding plug. One end of the first spring away from the first sliding plug is fixedly connected to the inner side wall of the driving chamber.

[0016] Furthermore, a second spring is fixedly connected to the second sliding plug. One end of the second spring away from the second sliding plug is fixedly connected to the inner bottom wall of the second driving cylinder.

[0017] Preferably, a driving part is fixedly connected to the support frame. A connecting rod is fixedly connected to the driving end of the driving part, and the connecting rod is fixedly connected to the mounting plate.

[0018] Preferably, a rubber pad is fixedly connected to the knocking plate.

[0019] Further, a supplementary air pipe is fixedly connected to the second driving cylinder. Check valves are arranged on both the supplementary air pipe and the first air pipe.

[0020] Furthermore, the second air pipe is an elastic hose.

[0021] Compared with the prior art, the present invention provides a forming device for an assembled precast wall panel, having the following beneficial effects:

[0022] 1. By arranging multiple groups of resistance sensors at the bottom of the mounting plate, the present invention can detect the change of internal resistance in real time after concrete pouring. When the resistance sensor comes into contact with the air bubbles in the concrete, the detected resistance value will decrease, so as to accurately judge whether there are air bubbles inside the concrete. Compared with the traditional detection method, the detection accuracy is greatly improved. And when the resistance sensor detects air bubbles, the solenoid valve is controlled to open, and the first sliding plug is pushed by the gas to make the knocking plate hit the side wall of the mold, generating vibration, effectively promoting the upward movement and discharge of the air bubbles in the concrete, reducing the residual amount of air bubbles in the concrete, reducing the possibility of hollowing after the subsequent concrete is formed, and effectively improving the forming quality of the concrete.

[0023] 2. During the reset process of the first sliding plug, the gas in the driving cavity is extruded and ejected through the air injection pipe, blowing on the surface of the resistance sensor, which can effectively blow off the impurities adhering to its surface. And a pressure relief valve can be set on the air injection pipe to further improve the cleaning effect on the surface of the resistance sensor by increasing the pressure of the ejected gas.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0033] Embodiment 1:

[0034] Refer to Figures 1 - 7 , a forming device for an assembled precast wall panel, including a mold 101 detachably connected to a bottom plate 1, and further including:

[0035] A support frame 2, fixedly connected to the bottom plate 1;

[0036] A mounting plate 5, connected to the support frame 2, and the mounting plate 5 is located directly above the mold 101;

[0037] Multiple groups of resistance sensors 501, fixedly connected to the mounting plate 5;

[0038] A first driving cylinder 4, fixedly connected to the side wall of the support frame 2, a first driving rod 4031 is slidably connected to the first driving cylinder 4, and a knocking plate 7 is fixedly connected to the first driving rod 4031;

[0039] The mounting plate 5 drives the resistance sensor 501 to move down and insert into the concrete in the mold 101. When the resistance sensor 501 encounters the blockage of air bubbles in the concrete, the resistance sensed by the resistance sensor 501 becomes smaller, and the first driving rod 4031 pushes the knocking plate 7 to strike the side wall of the mold 101.

[0040] A pressure accumulation chamber 401 and a driving chamber 403 are provided in the first driving cylinder 4. The pressure accumulation chamber 401 is connected to the driving chamber 403 through a connecting pipe 402. A first sliding plug 4033 is slidably connected in the driving chamber 403, and the first sliding plug 4033 is fixedly connected to the first driving rod 4031.

[0041] It should be noted that an electromagnetic valve available on the market is built in the connecting pipe 402, and the electromagnetic valve is electrically connected to the resistance sensor 501 through a controller.

[0042] A second driving cylinder 3 is fixedly connected to the support frame 2. A second sliding plug 302 is slidably connected in the second driving cylinder 3. A second driving rod 304 is fixedly connected to the second sliding plug 302. One end of the second driving rod 304 away from the second sliding plug 302 is fixedly connected to the mounting plate 5. A first air delivery pipe 301 is fixedly connected to the second driving cylinder 3. One end of the first air delivery pipe 301 away from the second driving cylinder 3 is communicated with the pressure accumulation cavity 401.

[0043] A second air delivery pipe 404 is fixedly connected to the side wall of the first driving cylinder 4. An air cavity 503 is formed in the mounting plate 5. One end of the second air delivery pipe 404 is communicated with the driving cavity 403, and the other end of the second air delivery pipe 404 is communicated with the air cavity 503. A jet pipe 504 is fixedly connected to the bottom of the mounting plate 5. The air outlet ends of multiple groups of jet pipes 504 face the resistance sensor 501.

[0044] A driving part 6 is fixedly connected to the support frame 2. A connecting rod 502 is fixedly connected to the driving end of the driving part 6. The connecting rod 502 is fixedly connected to the mounting plate 5.

[0045] It should be noted that the driving part 6 is a hydraulic cylinder that can be purchased on the market.

[0046] Refer to Figures 2 - 7 , during actual operation, the staff pours concrete into the mold 101 and starts the driving part 6. The driving part 6 will push the connecting rod 502 downward, and then push the mounting plate 5 fixedly connected with the resistance sensor 501 downward. When the mounting plate 5 moves downward for a certain distance, the resistance sensor 501 will be inserted into the concrete in the mold 101. At this time, the resistance sensor 501 will detect the upward resistance of the concrete. When there are air bubbles in the concrete, the downwardly inserted resistance sensor 501 will contact the air bubbles. At the moment when the resistance sensor 501 contacts the air bubbles, the resistance value received by the resistance sensor 501 will decrease. At this time, the resistance sensor 501 will sense the change in the resistance value and send the change signal to the solenoid valve through the controller. At this time, the solenoid valve in the communication pipe 402 will be opened. At this time, the gas in the pressure accumulation cavity 401 will enter the driving cavity 403 through the communication pipe 402. At this time, the first sliding plug 4033 in the driving cavity 403 will be pushed. When the first sliding plug 4033 is pushed, the first driving rod 4031 and the knocking plate 7 fixedly connected to it will move synchronously. At this time, the knocking plate 7 will impact on the side wall of the mold 101. At this time, the vibration generated by the impact will cause the air bubbles in the concrete to move upward and finally be discharged from the concrete.

[0047] The multiple groups of resistance sensors 501 arranged at the bottom of the mounting plate 5 in this device can detect the interior of the poured concrete, and thus can effectively detect whether there are air bubbles inside the concrete. By hitting the mold 101 with the hitting plate 7, the air bubbles in the concrete are shaken out through hitting and vibration, reducing the residual amount of air bubbles in the concrete, thereby reducing the possibility of hollowing after the subsequent concrete is formed and improving the forming quality of the concrete.

[0048] Refer to Figures 4 - 7 , during the reciprocating movement and detection process of the mounting plate 5, the mounting plate 5 will also drive the second driving rod 304 to move synchronously. When the second driving rod 304 moves downward, the second driving cylinder 3 will extract external air through the air supply pipe 305, and the extracted air will be stored in the second driving cylinder 3. When the second driving rod 304 is pushed upward, the second sliding plug 302 will squeeze out the gas in the second driving cylinder 3, and the squeezed gas will be input into the pressure accumulation chamber 401 through the first air pipe 301, and the gas input into the pressure accumulation chamber 401 will be stored. When the resistance sensor 501 detects that there are air bubbles in the concrete, the electromagnetic valve on the connecting pipe 402 will be opened for air release.

[0049] It should be noted that when the electromagnetic valve is releasing air, the resistance sensor 501 controls the electromagnetic valve to open and close intermittently through the controller, so as to reciprocally drive the hitting plate 7 to hit the mold 101, enabling the air bubbles in the concrete to be effectively discharged.

[0050] Refer to Figure 6 , Figure 7 , when the first sliding plug 4033 slides leftward to reset, the first sliding plug 4033 will squeeze out the gas in the driving chamber 403, and the squeezed gas is input into the air chamber 503 through the second air pipe 404. The gas entering the air chamber 503 will be ejected through the air ejection pipe 504, and the ejected gas will blow on the surface of the resistance sensor 501, thereby effectively blowing off the impurities adhering to the surface of the resistance sensor 501.

[0051] Refer to Figure 7 , in specific implementation, a pressure relief valve can also be set on the air ejection pipe 504. At this time, as the gas entering the air chamber 503 continuously increases, the pressure in the air chamber 503 will continuously increase. When the pressure in the air chamber 503 reaches the threshold value of the pressure relief valve, the gas in the air chamber 503 will be ejected through the air ejection pipe 504. By ejecting the gas under increased pressure, the cleaning effect of the air ejection pipe 504 on the surface of the resistance sensor 501 can be improved.

[0052] Refer to Figure 5 , in specific implementation, a first spring 4032 is fixedly connected to the first sliding plug 4033, and the end of the first spring 4032 away from the first sliding plug 4033 is fixedly connected to the inner side wall of the driving chamber 403.

[0053] Via the first spring 4032 fixedly connected to the first sliding plug 4033, the first sliding plug 4033 can be quickly reset.

[0054] Refer to Figure 6 , in specific implementation, a second spring 303 is fixedly connected to the second sliding plug 302, and one end of the second spring 303 away from the second sliding plug 302 is fixedly connected to the inner bottom wall of the second driving cylinder 3.

[0055] By arranging the second spring 303 in the second driving cylinder 3, the second sliding plug 302 can be quickly reset.

[0056] Refer to Figure 4 , Figure 6 , in specific implementation, a rubber pad 701 is fixedly connected to the knocking plate 7.

[0057] By arranging the rubber pad 701 on the knocking plate 7, when the knocking plate 7 impacts the mold 101, the mold 101 is not easily damaged due to rigid impact, thereby improving the service life of the mold 101.

[0058] A supplementary air pipe 305 is fixedly connected to the second driving cylinder 3, and one-way valves 8 are arranged on both the supplementary air pipe 305 and the first air delivery pipe 301.

[0059] It should also be noted that one-way valves 8 are arranged on both the communicating pipe 402 and the second air delivery pipe 404.

[0060] Refer to Figure 4 , Figure 6 , the second air delivery pipe 404 is an elastic hose.

[0061] By setting the second air delivery pipe 404 as an elastic hose, when the mounting plate 5 moves up and down, the second air delivery pipe 404 will not be torn off.

[0062] The above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
