Description

Technical Field

[0001] This invention relates to the field of construction engineering technology, specifically to a concrete pouring equipment for nuclear power engineering construction. Background Technology

[0002] Concrete pouring is usually an indispensable part of the construction process. Concrete pouring mainly refers to the process of pouring concrete into a mold until it solidifies.

[0003] For example, Chinese patent CN117145220A discloses a concrete pouring device for building construction. This device includes a mounting hole near the center of the outer wall of a lowering plate, with a rotating pipe rotatably installed within the mounting hole. The bottom end of the rotating pipe is located in a storage tank. A control valve is installed on the rotating pipe. A support rod is also provided on the top outer wall of the lowering plate, with a water guide pipe at its end. One end of the water guide pipe is rotatably connected to the top end of the rotating pipe. A push rod is also provided on the top outer wall of the rotating plate, with a gripping rod at its end. This invention can automatically achieve concrete mixing and subsequent storage. The cleaning of the storage tank, and the use of a swing discharge pipe, can make the pouring more uniform. The swing discharge pipe can automatically limit the position of the pouring equipment, making the swing pouring process more stable and the effect better. However, in the process of small-scale pouring, the concrete of existing concrete pouring equipment is prone to solidification when it is released to the ground, and special personnel are required to smooth the released concrete. In order to improve construction efficiency, the released concrete is smoothed and the internal concrete is allowed to solidify and adhere to the inner wall of the mixing tank.

A discharge pipe is installed on one side of the mixing tank, and a feed hopper is provided on the back.

[0028] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0029] 1. The concrete pouring equipment used in this nuclear power project construction utilizes a rotating rod to rotate, which in turn drives the mixing rod to rotate, thereby mixing the concrete in the mixing drum and preventing it from solidifying. At the same time, the contact block moves in a curved groove within the fixed block to limit its movement. During rotation, the contact block's rotation is further restricted by a plum blossom-shaped curved groove. This, combined with the action of the first spring, changes the position of the telescopic mixing rod and the wave-shaped mixing rod from the rotating rod, thereby improving the concrete mixing effect.

[0030] 2. The concrete pouring equipment used in the construction of this nuclear power project utilizes a contact block that moves within a curved groove in a fixed block. This movement is coordinated with a second spring to push a push rod that continuously extends and retracts. A third spring then pulls a striking rod, causing the striking block to impact the mixing drum, thus vibrating its outer wall and preventing concrete from adhering to the inner wall of the mixing drum.

[0031] 3. The concrete pouring equipment used in the construction of this nuclear power project utilizes the kinetic energy transmission of the rotating rod in conjunction with the first gear set to drive the rotating shaft to rotate. This rotation, in turn, drives the eccentric wheel installed on its outer wall to rotate, pushing the bottom vibrating plate downwards. This, in conjunction with the movement of its fixing rod within the second sleeve, causes the fixing rod to be pulled upwards and reset by the fourth spring. This, in turn, drives the vibrating plate to vibrate up and down, smoothing the concrete discharged from the discharge pipe.

[0032] 4. The concrete pouring equipment used in the construction of this nuclear power project uses the kinetic energy generated by the rotation of the shaft to drive the elliptical turntable to rotate. In conjunction with the fifth spring, the U-shaped landing gear on the outer wall of the elliptical turntable changes its vertical position, so that the top of the U-shaped landing gear impacts the outer wall of the mixing tank, which vibrates the bottom of the mixing tank and prevents the concrete at the bottom from solidifying.

[0033] 5. The concrete pouring equipment used in this nuclear power plant construction has its connecting rod position changed so that the scraper does not contact the mixing tank during operation, but contacts the inner wall of the mixing tank during cleaning. The rotating rod drives the connecting rod to rotate, which in turn pushes the scraper to rotate. The scraper moves within an annular slide rail via a top-mounted annular slider, improving stability. Furthermore, by providing auxiliary mixing when not in contact with the mixing tank, and scraping the inner wall when in contact, the cleaning effect is improved. Attached Figure Description

[0046] The mixing mechanism 3 includes: a rotating rod 301 and several mixing rods 302, a telescopic mixing rod 303, a wave-shaped mixing rod 304, a first spring 305, and an arc-shaped mixing rod 306. The rotating rod 301 is rotatably connected to the inner wall of the mixing tank 1 via bearings and extends to both ends. The several mixing rods 302 are evenly distributed in a circle and are fixedly connected by a ring on the outer wall of the rotating rod 301. The wave-shaped mixing rod 304 is fixedly connected to one end of the telescopic mixing rod 303, and its other end is driven by the first spring 305 to extend on the inner wall of the mixing rod 302. The arc-shaped mixing rod 306 is fixedly connected to the outer wall of the rotating rod 301 and is used to stir the concrete at the bottom of the mixing tank 1.

[0047] Specifically, the mixing mechanism 3 is configured to rotate the rotating rod 301, thereby rotating several mixing rods 302 fixedly connected to its outer wall, which in turn mixes the concrete inside the mixing tank 1. At the same time, the first spring 305 pushes the telescopic mixing rod 303 to slide inside the mixing rod 302, thereby pushing the wave-shaped mixing rod 304 fixedly connected to the other end to fully mix the concrete.

[0048] like Figure 4 , 6 As shown in Figure 7, the striking mechanism 4 includes: a fixed block 401, several contact blocks 402, and a push rod 403; the fixed block 401 is fixedly connected to the top of the inner cover of the mixing tank 1, and each contact block 402 is fixedly connected to the top of the wave-shaped stirring rod 304 and slidably connected in the curved groove opened at the bottom of the fixed block 401 to drive the wave-shaped stirring rod 304 to retract; the outer wall of the mixing tank 1 is provided with an installation groove and communicates with the curved groove, and the push rod 403 is set in the installation groove and pushed outward through the contact block 402; the curved groove is shaped like a plum blossom, and the contact block 402 is attached to the inner wall of the curved groove and contacts one side of the push rod 403; the striking mechanism 4 also includes: a second spring 404, a striking rod 405, and a striking block 409;

[0049] The diameters at both ends of the push rod 403 are larger than the diameter at the middle. The second spring 404 is sleeved on the middle of the outer wall of the push rod 403 and pushes the push rod 403 to move towards the curved slide groove. The striking rod 405 is fixedly connected to the push rod 403. Several striking blocks 409 are provided and fixedly connected to the inner side of the striking rod 405 for intermittently striking the mixing tank 1.

[0050] The outer wall of the mixing tank 1 is provided with a number of first sleeves 406. The inner wall of each first sleeve 406 is pulled by a third spring 408 to move the movable block 407 inserted into its inner wall. The movable block 407 is fixedly connected to the end of the striking rod 405 away from the push rod 403.

[0051] Specifically, the striking mechanism 4 utilizes its top contact block 402 to slide within a curved groove and intermittently rotate within the plum blossom-shaped groove, thereby pushing the wave-shaped stirring rod 304 to retract. Simultaneously, the first spring 305 pushes the telescopic stirring rod 303 to move outward, thus changing the distance between the wave-shaped stirring rod 304 and the rotating rod 301 during rotation, thereby improving the stirring effect. Simultaneously, the contact block 402, moving within the curved groove in conjunction with the second spring 404, changes the position of the push rod 403, thereby pushing the striking rod 405 to move and changing the striking block 409 to indirectly contact the outer wall of the mixing tank 1, achieving an impact effect.

[0052] like Figure 3 , 4 As shown in Figures 5 and 9, the vibration mechanism 5 includes: a mounting base 501, a rotating shaft 502, and a first gear set 503. The mounting base 501 is fixedly connected to the bottom of the outer wall of the mixing tank 1. The rotating shaft 502 is rotatably connected to the inner wall of the mounting base 501 through a bearing. The rotating shaft 502 is driven to rotate by the first gear set 503.

[0053] The vibration mechanism 5 also includes: an eccentric wheel 504, a vibrating plate 509, a second sleeve 510, and a fixing rod 511; four fixing rods 511 are provided and are fixedly connected to the top of the vibrating plate 509 in a circular and equal manner; the mixing tank 1 is sleeved on the outer wall of the fixing rod 511 through the second sleeve 510 fixedly connected to its bottom; a fourth spring is provided on the inner wall of the second sleeve 510 and is fixedly connected to the second sleeve 510 and the fixing rod 511; two eccentric wheels 504 are provided and are eccentrically fixedly sleeved on the outer wall of the rotating shaft 502, and the outer circumference of the eccentric wheel 504 is in contact with the top of the vibrating plate 509; the two ends of the rotating shaft 502 respectively movably pass through the mounting base 501 and extend outward, and the extended ends are provided with a striking mechanism to assist in cleaning the inner wall of the mixing tank 1;

[0054] Specifically, the vibration mechanism 5 is set up, and the rotation of the rotating rod 301 drives the rotating shaft 502 to rotate through the first gear set 503, which in turn drives the eccentric wheel 504 on its outer wall to rotate, thereby pushing the vibrating plate 509 to move up and down. This, in conjunction with the fourth spring, pulls the fixing rod 511 to contract on the inner wall of the second sleeve 510, thereby generating up and down vibration to smooth out the discharged concrete.

[0055] like Figure 9As shown, the striking mechanism includes: an elliptical turntable 505, a U-shaped landing gear 506, a fixed plate 507, and a fifth spring 508; the fixed plate 507 is fixedly connected to the side of the mounting base 501, the U-shaped landing gear 506 passes through the mounting base 501 and moves upward to fit against the bottom of the mixing tank 1, a limit plate is installed on the outer wall of the U-shaped landing gear 506, and the fifth spring 508 installed above it pushes the U-shaped landing gear 506 to move upward, the inner side of the U-shape of the U-shaped landing gear 506 fits against the outer wall of the elliptical turntable 505, pushing the U-shaped landing gear 506 to move downward, the first gear set 503 includes two bevel gears, which are respectively installed on the extension end of the rotating rod 301 and the outer wall of the rotating shaft 502, the outer wall of the rotating rod 301 is provided with a threaded groove, and two threaded sleeves are provided on both sides of the bevel gears on the outer wall of the rotating rod 301.

[0056] Specifically, the impact mechanism utilizes the rotation of the rotating shaft 502 to drive the elliptical turntable 505 to rotate, thereby pushing the U-shaped landing gear 506 downward. In conjunction with the fifth spring 508, the U-shaped landing gear 506 is reset upward, pushing its top to contact the bottom of the mixing tank 1, generating an impact effect and causing vibration of the concrete on its inner wall.

[0057] like Figure 2 , 6 As shown in Figures 7 and 8, the inner wall scraping mechanism 8 includes a connecting rod 801 and a scraper 802. The scraper 802 is fixedly connected to the outer wall of the rotating rod 301 via the connecting rod 801 and rotates with it. The inner wall scraping mechanism 8 also includes an annular slide 803, an annular slider 804, a sixth spring 805, and an adjusting screw 806. The annular slide 803 is fixedly connected to the inner wall of the mixing tank 1, and the annular slider 804 is slidably connected within the annular slide 803. The annular slider 804 has a circular groove. The scraper 802 is pulled towards the annular slider 804 by the sixth spring 805. The rotating rod 301 is hollow inside, and the adjusting screw 806 is threadedly connected inside the rotating rod 301. One end of the connecting rod 801 movably passes through the rotating rod 301 and contacts the outer wall of the adjusting screw 806.

[0058] The bottom of the adjusting screw 806 is tapered. By adjusting the tapered surface to contact the connecting rod 801, the connecting rod 801 is moved. The top of the mixing tank 1 is connected to a support rod and is fixedly connected to the top of the inner wall of the outer cylinder 2. The top of the mixing tank 1 is fixedly installed with a motor 10. The motor 10 drives the rotating rod 301 to rotate through the second gear set 9. The top of the vibrating plate 509 is provided with a handrail 6 and is fixedly connected to the outer wall of the mixing tank 1 through a reinforcing rod. The bottom of the handrail 6 is inserted with a round rod and fixedly connected to the top of the vibrating plate 509. A discharge pipe 7 is installed on one side of the mixing tank 1 and a feed hopper is provided on the back.

[0059] Specifically, the inner wall scraping mechanism 8 utilizes the annular slider 804 that slides on the inner wall of the annular slide 803. Rotation of the slider 804 causes the scraper 802, fixed to its outer wall, to rotate, which in turn rotates the connecting rod 801. This rotation of the scraper 802 then mixes the concrete on the inner wall of the mixing tank 1. When cleaning the inner wall of the mixing tank 1 is required, the adjusting screw 806 is rotated to push the connecting rod 801, causing the scraper 802 to fit against the inner wall of the mixing tank 1, thus scraping the inner wall. Simultaneously, adjusting the two threaded sleeves disengages the first gear set 503, stopping the vibration mechanism 5. The inner wall of the mixing tank 1 is then cleaned through the simultaneous operation of the mixing mechanism 3, the striking mechanism 4, the vibration mechanism 5, the impact mechanism, and the inner wall scraping mechanism 8.

[0060] The working principle of this invention is as follows:

[0061] When pouring concrete, the concrete pouring equipment is used to pour concrete into the mixing tank 1 at the construction site and then lay it out using the equipment. The release of concrete is controlled by the control valve on the discharge pipe 7. At this time, the motor 10 is controlled to rotate by the control switch, which in turn drives the rotating rod 301 to rotate through the second gear set 9. This drives the mixing rod 302 on the outer wall of the rotating rod 301 to rotate, thereby mixing the concrete on the inner wall of the mixing tank 1 and preventing solidification. At the same time, when the rotating rod 301 rotates, the curved groove on its fixing block 401 limits the contact block 402, thereby changing the rotation path of the contact block 402. When the contact block 402 approaches the rotating rod 301 in the curved groove, it tends to move towards the rotating rod 301. This, together with the first spring 305, pushes the telescopic mixing rod 303 to move, thereby changing the intermittent movement of the wave-shaped mixing rod 304 away from and towards the rotating rod 301, resulting in a better mixing effect.

[0062] Meanwhile, when the contact block 402 moves in the curved groove, it contacts the push rod 403, generating a force to squeeze the push rod 403 outward, and a force to push the push rod 403 inward through the second spring 404. Since the contact block 402 intermittently generates the force generated by the push rod 403, it will pull the striking rod 405 to be pushed open and pulled back intermittently, so that the striking block 409 on its inner side will hit the mixing tank 1, causing the nickel in the mixing tank 1 to vibrate, preventing the concrete on its inner wall from sticking to the inner wall of the mixing tank 1. At the same time, the third spring 408 pulls the movable block 407, improving the stability of the striking rod 405 when it reciprocates.

[0063] Simultaneously, the concrete discharged through the discharge pipe 7 is driven by the rotation of the rotating rod 301, which in turn drives the rotating shaft 502 to rotate via the transmission of kinetic energy through the first gear set 503. This, in turn, causes the eccentric wheel 504 on its outer wall to generate intermittent contact energy with the vibrating plate 509. This, combined with the movement of the second sleeve 510 at the bottom of the mixing drum 1 on the fixed rod 511 and the reset by the internal fourth spring, allows the vibrating plate 509 to vibrate up and down, thereby continuously smoothing the concrete on the ground. At the same time, the concrete... The elliptical turntables 505 on both sides rotate, and the U-shaped landing gear 506 connected to the fixed plate 507 is pulled by the fifth spring 508 to make the U-shaped landing gear 506 fit against the bottom of the mixing tank 1. As the elliptical turntables 505 rotate, the outer wall side away from the center contacts the U-shaped landing gear 506. Under the pull of the fifth spring 508, when the outer wall near the center of the circle contacts the U-shaped landing gear 506, the U-shaped landing gear 506 hits the bottom of the mixing tank 1, thereby generating vibration on the bottom of the tank.

[0064] Meanwhile, the inner wall scraping mechanism 8 inside the mixing tank 1 uses the rotation of the rotating rod 301 to drive the connecting rod 801 to rotate, which in turn drives the scraper 802 to rotate. It also works with the annular slider 804 to slide on the annular slide rail 803 to achieve stable mixing. At the same time, by rotating the adjusting screw 806, its conical outer wall contacts the connecting rod 801, pushing the scraper 802 to contact the inner wall of the mixing tank 1, thereby scraping the inner wall of the mixing tank 1.

[0065] When the work is stopped, the inner wall of the mixing tank 1 needs to be cleaned. At this time, the valve on the discharge pipe 7 is closed, and water is poured into the mixing tank 1. By rotating the two threaded sleeves, the gear on the outer wall of the rotating shaft 502 is pushed, so that the first gear set 503 is disengaged. By rotating the adjusting screw 806, its conical outer wall contacts the connecting rod 801, pushing the scraper 802 to contact the inner wall of the mixing tank 1, thereby scraping the inner wall of the mixing tank 1. At this time, the motor 10 is started, and the second gear set 9 drives the mixing mechanism 3 to rotate. Similar to when mixing concrete, the striking mechanism 4 is driven to strike the outer wall of the mixing tank 1, the impact mechanism is driven to strike the bottom of the mixing tank 1, and the inner wall scraping mechanism 8 is driven to scrape the inner wall of the mixing tank 1, thereby achieving a better cleaning effect on the inner wall of the mixing tank 1.

[0066] This invention provides a concrete pouring device for nuclear power plant construction. Many methods and approaches exist to implement this technical solution; the above description is merely a preferred embodiment. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this invention, and these improvements and modifications should also be considered within the scope of protection of this invention. All components not explicitly stated in this embodiment can be implemented using existing technology.
