Description

Technical Field

[0001] The present application relates to the technical field of concrete mixing plants, and in particular to an intelligent monitoring system for a mixing plant's lower silo. Background Art

[0002] A concrete mixing plant, also known as a concrete precasting plant, is a combined unit used for centralized concrete mixing. It is commonly used in large and medium-sized water conservancy, power, and bridge projects, which require large quantities of concrete, require long construction periods, and have concentrated construction sites. A concrete mixing plant consists of a mixing station frame, which is equipped with upper and lower supports. The lower supports house the concrete mixer, while the upper supports are equipped with a discharge device, which typically includes a cement hopper, a sand and gravel hopper, an additive hopper, and a water hopper. The discharge device delivers a proportionate amount of water, cement, sand and gravel, and additives to the concrete mixer. The materials are then mixed into a uniform concrete mixture in the concrete mixer, which is then discharged from the concrete mixer's discharge pipe into a concrete truck, which then transports the concrete to the construction site.

[0003] Since concrete has a certain viscosity, a small amount of concrete will inevitably adhere to the wall of the discharge pipe during the unloading process. After a period of time, this part of the concrete will harden and firmly adhere to the wall of the discharge pipe. Therefore, after multiple unloading, the aperture of the discharge pipe for concrete to fall and discharge will become narrower and narrower, eventually leading to blockage. Therefore, it is very necessary to monitor the discharge pipe of the concrete mixer for anti-blocking.

[0004] In the related art, in order to achieve the purpose of monitoring the discharge pipe of a concrete mixer, a camera is installed to monitor the discharge pipe in real time. The thickness of the concrete attached to the discharge pipe is manually observed by the naked eye to see if it has reached a level that will affect the discharge. If the concrete thickness is thick, the concrete attached to the inner wall of the discharge pipe is manually cleaned with a shovel or steel chisel to prevent the concrete from accumulating and causing blockage. However, the use of cameras for monitoring and manual observation is prone to unclear observation due to factors such as ambient light and observation angle, resulting in inaccurate monitoring of the concrete thickness on the inner wall of the discharge pipe. As a result, the pipe wall cannot be cleaned in a timely manner, increasing the probability of blockage during the discharge process and affecting the normal discharge of concrete. Summary of the Invention

[0005] The purpose of this application is to provide an intelligent monitoring system for the discharge hopper of a mixing station, which is used to solve the problem that the monitoring system in the prior art is not accurate enough in monitoring the thickness of concrete on the inner wall of the discharge pipe of a concrete mixer, resulting in easy blockage of the discharge pipe.

[0016] By adopting the above technical solution, the third driving member drives the discharge pipe to rotate through the transmission mode of meshing the driven gear and the driving gear.

When the compression spring is compressed, the pressure applied to the slider increases, and this pressure is monitored by the first pressure sensor. The greater the pressure, the greater the swing amplitude of the rocker arm and the thicker the hardened concrete layer on the inner wall of the discharge pipe. When the pressure value monitored by the first pressure sensor reaches a certain critical value, it means that the thickness of the hardened concrete layer on the inner wall of the discharge pipe has reached a level that affects the normal unloading of concrete. At this time, the staff clears the hardened concrete layer on the inner wall of the discharge pipe, so that the concrete thickness on the inner wall of the discharge pipe can be accurately monitored, and the pipe wall can be cleaned in time, reducing the chance of blockage during the discharge process and avoiding affecting the normal unloading of concrete.

[0047] The following is combined with Figure 1 -Attached Figure 10 , further details of this application are given.

[0048] The embodiment of the present application discloses an intelligent monitoring system for a mixing station discharge silo.

[0049] Reference Figure 1 and Figure 2An intelligent monitoring system for a concrete mixing station discharge silo includes a frame 10, a discharge hopper 20, a discharge pipe 30, a detection device 40, a scraping device 50, a reinforcement device 60, a blocking mechanism 70, a base frame 80, and a second pressure sensor 90. The second pressure sensor 90 is fixed to the base frame 80, the frame 10 is fixed to the second pressure sensor 90, the discharge hopper 20 is fixed to the frame 10, and the discharge pipe 30 is connected to the discharge hopper 20. The discharge hopper 20 is arranged below the concrete mixer but is not connected to the concrete mixer. The second pressure sensor 90 is electrically connected to the signal conversion and display equipment in the control room. The concrete mixed in the concrete mixer is discharged into the discharge hopper 20 and then discharged to the concrete transport truck through the discharge pipe 30. The concrete transport truck then transports the concrete to the construction site. The weight of the frame 10, the discharge hopper 20 and the discharge pipe 30 is monitored by the second pressure sensor 90. When the weight monitored by the second pressure sensor 90 exceeds the maximum critical value, it means that excessive concrete has accumulated in the discharge hopper 20 or the discharge pipe 30, and the discharge hopper 20 or the discharge pipe 30 has been blocked to varying degrees. Then, the staff rushes to the unloading site to clear the discharge hopper 20 and the discharge pipe 30 to eliminate the blockage in time.

[0050] Reference Figure 3 and Figure 4 The detection device 40 includes a rocker arm 41, a cylinder 42, a slider 43, a telescopic rod 44, a compression spring 45, a first pressure sensor 46, a bracket 47 and a moving mechanism 48. The moving mechanism 48 is arranged on the frame 10 and connected to the bracket 47. The moving mechanism 48 can drive the bracket 47 to move along the axial direction of the discharge pipe 30. The cylinder 42 is hinged to the bracket 47 through a first pin shaft 421. The first pressure sensor 46 is fixed in the cylinder 42, and the slider 43 is slidably arranged in the cylinder 42. The slider 43 abuts against the pressure measuring end of the first pressure sensor 46, and the first pressure sensor 46 is electrically connected to the signal conversion and display equipment in the control room. The telescopic rod 44 is slidably inserted into the cylinder 42. The telescopic rod 44 is provided with an anti-slip plate 442 to prevent it from slipping out of the cylinder 42. The compression spring 45 is located in the cylinder 42. The two ends of the compression spring 45 are respectively in contact with the slider 43 and the telescopic rod 44. The rocker arm 41 is hinged to the bracket 47 through one end of the second pin shaft 413. The other end of the rocker arm 41 can contact the inner wall of the discharge pipe 30. The end of the telescopic rod 44 located outside the cylinder 42 is hinged to the rocker arm 41 through the third pin shaft 441.

[0051] Since concrete has a certain viscosity, a small amount of concrete will inevitably adhere to the wall of the discharge pipe 30 during the unloading process. After a period of time, this part of the concrete will harden and firmly adhere to the wall of the discharge pipe 30. After multiple unloading, the aperture of the discharge pipe 30 for the concrete to fall and discharge will become narrower and narrower, eventually leading to blockage. Therefore, during the period when the discharge pipe 30 is not unloading concrete, the pendulum 41 is placed under the discharge pipe 30, and the vertical distance from the end of the pendulum 41 close to the side wall of the discharge pipe 30 to the axis of the discharge pipe 30 is greater than the inner diameter of the discharge pipe 30. Then, the bracket 47 is driven to move upward along the axis of the discharge pipe 30 by the moving mechanism 48. After the pendulum 41 enters the discharge pipe 30, the end of the pendulum 41 close to the side wall of the discharge pipe 30 contacts the hardened layer of concrete on the inner wall of the discharge pipe 30, thereby forcing the pendulum 41 to rotate around the second pin 413 toward Figure 4 The first pressure sensor 46 detects the pressure of the sliding block 43, and the second pressure sensor 46 detects the pressure of the sliding block 43. When the first pressure sensor 46 detects the pressure of the sliding block 43, the sliding block 43 is pressed against the first pressure sensor 46, and the pressure of the sliding block 43 is increased ...

[0052] Reference Figure 3 The moving mechanism 48 includes a first driving member 481, a first lifting member 482, and a second driving member 483. The first driving member 481 is fixed to the frame 10. The first lifting member 482 is connected to the first driving member 481 and is used to drive the first lifting member 482 to move upward and downward. The second driving member 483 is fixed to the first lifting member 482. The bracket 47 is connected to the second driving member 483 and is used to rotate the bracket 47. The rotation axis of the bracket 47 is parallel to the axis of the discharge tube 30. The discharge tube 30 is arranged in a vertical direction. The first driving member 481 drives the first lifting member 482 to move upward and downward, thereby driving the swing arm 41 to move along the axis of the discharge tube 30. The second driving member 483 drives the bracket 47 to rotate, thereby moving the bracket 47, the swing arm 41, the cylinder 42, and the telescopic rod 44 away from under the discharge tube 30 to prevent interference with the normal discharge of concrete.

[0054] Reference Figure 4 and Figure 5 The detection device 40 also includes a winding wheel 49, a wire pulling wire 410 and a wire taking-up motor 411. The winding wheel 49 is rotatably mounted on the bracket 47, and the wire taking-up motor 411 is fixedly mounted on the bracket 47. The wire taking-up motor 411 is connected to the winding wheel 49. More specifically, the wire taking-up motor 411 can be connected to the winding wheel 49 through a transmission structure such as a synchronous belt 412. The wire taking-up motor 411 is used to drive the winding wheel 49 to rotate, and the two ends of the wire pulling wire 410 are respectively fixed to the winding wheel 49 and the rocker arm 41.

[0055] When it is necessary to drive the first lifting member 482 downward through the first driving member 481 to move the rocker arm 41 out of the discharge pipe 30, the winding wheel 49 is driven to rotate by the wire-reeling motor 411 to reel in the pull wire 410, so that the rocker arm 41 rotates to a certain angle, and the end of the rocker arm 41 close to the side wall of the discharge pipe 30 is separated from the hardened concrete layer on the inner wall of the discharge pipe 30, thereby reducing the resistance of the rocker arm 41 when it is moved out of the discharge pipe 30.

[0059] When the concrete is unloaded, the fourth and fifth drive members 53 and 55 drive the scraper 52 to move upward and downward, bringing the side edges of the scraper 52 into contact with the inner wall of the discharge tube 30. The third drive member 51 then drives the discharge tube 30 to rotate, scraping away the unhardened concrete on the inner wall of the discharge tube 30. When the concrete is unloaded, the fourth and fifth drive members 53 and 55 remove the scraper 52 from the discharge tube 30 to prevent it from interfering with the normal discharge of concrete.

[0060] Reference Figure 1 and Figure 7 The fourth driving member 53 can adopt a fourth cylinder 531. The specific connection relationship between the fourth cylinder 531 and the second lifting member 54 is as follows: the fourth cylinder 531 is fixed on the frame 10 through the second support 533, the second lifting member 54 is fixedly connected to the fourth piston rod 532 of the fourth cylinder 531, the second lifting member 54 is provided with a second guide rod 541, the second support 533 is provided with a second guide hole, and the second guide rod 541 is slidably passed through the second guide hole.

The connecting rod 61 can be detachably connected to the scraper 52.

[0063] When the scraper 52 is used to scrape and clean the unhardened concrete on the inner wall of the discharge pipe 30, since only the bottom of the scraper 52 is fixed to the first translation member 56, the structure is unstable and it is easy to bend during the scraping process. In order to ensure that the scraper 52 has sufficient strength and does not bend, before the scraping begins, the sixth driving member 63 drives the connecting rod 61 to move toward the scraper 52, and the connecting rod 61 is connected to the scraper 52, so that the upper and lower parts of the scraper 52 are fixedly supported, thereby improving the strength of the scraper 52.

[0070] During concrete unloading, the scraper 52 and connecting rod 61 must be removed from the discharge tube 30 to avoid interference with the normal unloading of the concrete. After the connecting rod 61 is removed from the guide tube 21, the seventh and eighth driving members 72 and 73 drive the column 74 to move and insert the column 74 into the guide tube 21. This prevents concrete from entering the guide tube 21 during unloading and blocking the sliding movement of the connecting rod 61 within the guide tube 21.

[0072] The implementation principle of the intelligent monitoring system for the discharge hopper of a mixing station in this embodiment is as follows: the concrete mixed in the concrete mixer is discharged into the discharge hopper 20, and then discharged to the concrete transport vehicle through the discharge pipe 30. The concrete transport vehicle then transports the concrete to the construction site. The weight of the frame 10, the discharge hopper 20 and the discharge pipe 30 is monitored by the second pressure sensor 90. When the weight monitored by the second pressure sensor 90 exceeds the maximum critical value, it means that there is excessive concrete accumulated in the discharge hopper 20 or the discharge pipe 30, and the discharge hopper 20 or the discharge pipe 30 is blocked to varying degrees, and the discharge hopper 20 and the discharge pipe 30 need to be cleared.

[0073] After concrete discharge is complete, the fourth and fifth drive members 53 and 55 drive the scraper 52 to rise and fall and translate, bringing the side edges of the scraper 52 into contact with the inner wall of the discharge tube 30. The sixth drive member 63 then drives the connecting rod 61 into the locking hole 571. Through the tapered head 612 and the first wedge-shaped locking block 68, the connecting rod 61 is locked to the scraper 52, securing both the upper and lower portions of the scraper 52. The third drive member 51 then drives the discharge tube 30 to rotate, and during this rotation, the scraper 52 scrapes away any unhardened concrete on the inner wall of the discharge tube 30. After the scraper finishes cleaning, the ninth driving member 65 drives the stem 64 into the unlocking hole 572. The end of the stem 64 pushes the second wedge-shaped locking block 69 back into the second chute 576. This, in turn, drives the first wedge-shaped locking block 68 back into the first chute 574 via the second connecting rod 691, the connecting plate 610, and the first connecting rod 681, separating the cone head 612 from the first wedge-shaped locking block 68 and unlocking the scraper. The sixth driving member 63 then drives the connecting rod 61 out of the locking hole 571 and the guide tube 21. The seventh and eighth driving members 72 and 73 drive the column 74 to move and insert it into the guide tube 21, preventing concrete from entering the guide tube 21 and blocking the sliding of the connecting rod 61 during the next unloading process. The fourth and fifth driving members 53 and 55 then remove the scraper 52 from the discharge tube 30 to prevent interference with the next concrete discharge.

[0074] After the scraper finishes cleaning, the bracket 47 is driven by the moving mechanism 48 to move upward along the axis of the discharge pipe 30. When the swing arm 41 enters the discharge pipe 30, the end of the swing arm 41 close to the side wall of the discharge pipe 30 contacts the hardened concrete layer on the inner wall of the discharge pipe 30, thereby forcing the swing arm 41 to rotate around the second pin 413. Figure 4 The first pressure sensor 46 detects the pressure of the sliding block 43, and the second pressure sensor 46 detects the pressure of the sliding block 43. When the first pressure sensor 46 detects the pressure of the sliding block 43, the sliding block 43 is pressed against the first pressure sensor 46, and the pressure of the sliding block 43 is increased ...
