Description

Technical Field

[0001] The present invention relates to the technical field of concrete construction equipment, and specifically relates to a rolling leveling apparatus for concrete construction and a leveling method thereof. Background Art

[0002] Concrete, abbreviated as "tóng", is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. The term concrete in general refers to cement concrete obtained by using cement as a cementitious material, sand and stone as aggregates, and mixing with water in a certain proportion, also known as ordinary concrete, which is widely used in civil engineering.

[0003] Concrete leveler is a commonly used device in concrete construction, which can smooth the uneven surface of concrete by applying vibration to wet concrete, so as to improve the flatness of the concrete pavement. At the same time, the arrangement of the concrete leveler can improve the efficiency during concrete construction.

[0004] At present, when the concrete levelers on the market are in use, most of them need to lay the concrete on the ground first, and then place the concrete leveler on the concrete surface. When the concrete is leveled by pushing, concrete will overflow from both sides of the concrete leveler, which makes the existing concrete levelers unable to achieve precise conveying and prevent side-end overflow. Therefore, it is necessary to develop a device to solve the above problems. Summary of the Invention

[0009] Specifically, the flow guiding device includes a connecting pipe, a second gear, a conveying cylinder, a spiral blade, a supporting cavity, a nozzle, and an L-shaped connecting pipe. The nozzle is fixedly installed at the bottom end of the L-shaped connecting pipe. The L-shaped connecting pipe is equidistantly fixedly installed on the rear end of the supporting cavity.

The second threaded rod is threadedly inserted into the top end of the connecting block.

[0015] A leveling method using a concrete roller leveling device includes the following steps:

[0016] S1. First, fix the collection device to the external drive equipment, then pour the concrete into the inside of the collection device. The collection device is connected to the inside of the connecting pipe, so that the concrete can flow into the inside of the conveying cylinder. At this time, the third gear can be connected to the external motor shaft, and the motor can be started so that the third gear can rotate. When the third gear rotates, it can drive the second gear and the spiral blade to rotate at the same time, so that the concrete can be stably conveyed into the inside of the nozzle. Since the nozzle is perpendicular to the ground, the concrete can be conveyed to the ground.

[0017] S2. Then, start the drive equipment to move the whole device until the bottom of the vibrator passes the top of the concrete, so that the surface of the concrete can be leveled. At the same time, the hydraulic cylinder can be turned on to move the synchronous rod downward into the interior of the concrete, thereby preventing air bubbles from remaining inside the concrete.

[0018] S3. Finally, when the third gear is rotating, it can drive the worm to rotate on the top of the worm wheel through the connecting shaft, so that the worm wheel can drive the first gear and the transmission belt to rotate at the same time, causing the agitator to push the excess concrete at the edge of the vibrator to the front end, thus preventing the concrete from accumulating excessively on both sides of the vibrator.

[0019] The beneficial effects of this invention are:

[0020] First, this invention uses a collection device to transport concrete into the conveying cylinder. When the third gear rotates, it can drive the scraper to perform cyclic sweeping of the ground, thereby improving the cleanliness of the ground. Furthermore, the third gear can drive the second gear and the spiral blade to rotate simultaneously via a chain, so that while the scraper cleans the ground, the spiral blade can also perform the work of cyclically and stably conveying concrete. Finally, the nozzle delivers the concrete to the ground, completing the work of precise concrete delivery.

[0021] Second, the present invention drives the connecting shaft and worm to rotate through the third gear, and the worm can indirectly drive the actuating plate to rotate through the worm wheel, so that the actuating plate can perform the work of cyclically pushing excess concrete outward. Furthermore, the bottom end of the actuating plate is flush with the bottom end of the vibrator, which can prevent the actuating plate from damaging the surface flatness of the concrete and complete the work of preventing the concrete from moving out to the side.

[0041] like Figure 8 The flow guiding device 22 includes a connecting pipe 24, a second gear 25, a conveying cylinder 26, a spiral blade 27, a supporting cavity 28, a nozzle 29, and an L-shaped connecting pipe 30.

The connecting pipe 24, the conveying cylinder 26, the L-shaped connecting pipe 30, and the nozzle 29 are interconnected, so that concrete can be conveyed to the ground by the nozzle 29.

[0042] like Figure 9 The synchronization device 23 includes a front support plate 31, a scraper 32, a chain 33, a connecting shaft 34, a third gear 35, a first threaded rod 36, a guide rod 37, and an extension base plate 38.

By screwing the first threaded rod 36, the scraper 32 is driven to move up and down, so that the scraper 32 can always be in contact with the ground.

[0043] The collecting device 2 is fixedly installed at the front end of the connecting pipe 24, the worm gear 13 is fixedly installed at the rear end of the connecting shaft 34, the protective cover 21 is fixedly installed on the inner surface of the side plate 15 near the vibrating rod 12, the worm wheel 19 meshes with the worm gear 13, the bottom end of the second gear 25 meshes with the top end of the chain 33, and the front end support plate 31 is fixedly installed at the bottom front end of the support cavity 28, which can support the third gear 35 to perform power transmission.

[0044] The support frame 14 has scale lines marked on both ends, and vertical sliding grooves adapted to the key 9 are opened inside both ends of the support frame 14. The bottom end of the actuating plate 20 is horizontally aligned with the bottom end of the vibrator 16. The connecting pipe 24, the collecting device 2, the conveying cylinder 26, the L-shaped connecting pipe 30 and the nozzle 29 are interconnected, which can transfer concrete to the ground.

[0045] The nozzle 29 is located at the front end of the vibrator 16. The side plate 15 has a base hole inside its side end, and the round rod of the first gear 18, which is close to the center of the side end of the worm gear 19, is rotatably installed inside the base hole, which can support the first gear 18 to perform transmission work.

[0046] A leveling method using a concrete roller leveling device includes the following steps:

[0047] S1. First, the collecting device 2 is fixedly installed on the external driving equipment. Then, the concrete is poured into the inside of the collecting device 2. The collecting device 2 is connected to the inside of the connecting pipe 24, so that the concrete can flow into the inside of the conveying cylinder 26. At this time, the third gear 35 can be connected to the external motor shaft, and the motor is started so that the third gear 35 can rotate. When the third gear 35 rotates, it can drive the second gear 25 and the spiral blade 27 to rotate at the same time, so that the concrete can be stably conveyed into the inside of the nozzle 29. Since the nozzle 29 is perpendicular to the ground, the concrete can be conveyed to the ground.

[0048] S2. Then, start the drive equipment to move the whole device until the bottom of the vibrator 16 passes the top of the concrete, so that the surface of the concrete can be leveled. At the same time, the hydraulic cylinder 10 can be turned on to drive the synchronous rod 11 to move downward into the interior of the concrete, thereby preventing air bubbles from remaining inside the concrete.

[0049] S3. Finally, when the third gear 35 is rotating, the worm 13 can be driven to rotate on the top of the worm wheel 19 through the connecting shaft 34, so that the worm wheel 19 can drive the first gear 18 and the transmission belt 17 to rotate at the same time, causing the actuating plate 20 to push the excess concrete at the edge of the vibrator 16 to the front end, avoiding excessive accumulation of concrete on both sides of the vibrator 16.

[0050] The working principle of Example 1 is as follows: In use, the collecting device 2 is first installed on an external drive unit, and the third gear 35 is connected to an external motor. Concrete is then poured into the collecting device 2. The collecting device 2 communicates with the connecting pipe 24, allowing the concrete to flow through the connecting pipe 24 into the conveying cylinder 26. Afterward, the external motor is turned on, causing the third gear 35 to rotate. When the third gear 35 rotates, it meshes with the chain 33, allowing the third gear 35 to drive the second gear 25 to rotate. When the second gear 25 rotates, it drives the spiral blades 27 to circulate inside the conveying cylinder 26, thus conveying the concrete inside the conveying cylinder 26 through the L-shaped connecting pipe 30. The concrete flows into the nozzle 29, which is vertically aligned with the ground, allowing it to flow onto the surface. Aligning the nozzle 29 with the vibrator 16 activates the external drive unit, moving the entire device. Then, the vibrator 12 and vibrator 16 are activated, allowing the vibrator 16 to level the concrete surface. Next, the hydraulic cylinder 10 is activated, moving the vibrator 12 downwards to vibrate the inner layers of the concrete, preventing air bubbles from forming. Simultaneously, the external drive unit moves the vibrator 16 across the concrete surface. Excess concrete accumulates on both sides of the vibrator 16, and the side plates 15 prevent it from spilling out. Meanwhile, when the third gear 35 rotates, it drives the connecting shaft 34 and the worm gear 13 to rotate, which in turn drives the worm wheel 19 to rotate. When the worm wheel 19 rotates, it drives the transmission belt 17 to rotate reciprocally through the first gear 18, so that the actuating plate 20 can push the concrete located on both sides inside the vibrator 16 to the front end, preventing excessive accumulation of concrete on both sides inside the vibrator 16. At the same time, when the third gear 35 rotates, it drives the scraper 32 to rotate reciprocally. Since the scraper 32 is lower than the vibrator 16, it can scrape impurities on the ground to the side, improving the cleanliness of the ground. Furthermore, when the scraper 32 is in use, the first threaded rod 36 can be rotated to move the scraper 32 up and down, thereby adjusting the position of the scraper 32. The guide rod 37 is slidably inserted into the inside of the extension base plate 38, ensuring that the scraper 32 moves up and down in a straight line to remove impurities from the ground. During use, when the hydraulic cylinder 10 is activated, the vibrator 12 slides in the guide grooves inside both ends of the support top frame 14 via the locking key 9, ensuring that the vibrator 12 moves up and down in a straight line. The upper surfaces of both ends of the support top frame 14 are marked with scale lines, allowing the user to precisely control the distance the vibrator 12 descends. During use, the vibrator 12 shares the same power source as the vibrator 16, reducing energy waste. Simultaneously, the protective cover 21 located on both sides of the transmission toothed belt 17 prevents concrete from entering between the transmission toothed belt 17 and the first gear 18.To prevent the transmission toothed belt 17 from jamming during use.

[0051] Example 2

[0052] Based on Example 1, such as Figure 10 As shown, the support base frame 8 also includes a guide rail 39, a second threaded rod 40, a protective side plate 41, and a connecting block 42. The guide rail 39 is symmetrically fixedly installed at both ends of the support base frame 8. The connecting block 42 is slidably sleeved on the guide rail 39. The protective side plate 41 is fixedly installed on the bottom end of the connecting block 42 away from the guide rail 39. The second threaded rod 40 is threadedly inserted into the top end of the connecting block 42.

[0053] In implementing this embodiment, when the nozzle 29 is conveying concrete, the connecting block 42 can be moved downward until the protective side plate 41 contacts the ground, so that the protective side plate 41 can prevent concrete from flowing out from the side. At the same time, by sliding the connecting block 42 on the guide rail 39, the protective side plate 41 can be ensured to move up and down in a straight line. When the protective side plate 41 moves to the specified height, the second threaded rod 40 can be screwed and rotated to be fastened to the support base 8, so that the protective side plate 41 can be fixed and restricted at the specified height, preventing the protective side plate 41 from sliding up and down again, thus completing the work.

[0054] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

The concrete rolling leveling equipment according to claim 3, characterized in that: The nozzle (29) is located at the front end of the vibrator (16), and a base hole is opened inside the side end of the side plate (15). The round rod of the first gear (18) near the center of the side end of the worm gear (19) is rotatably installed inside the base hole.

5. A concrete rolling leveling device according to claim 4, characterized in that: The support frame (8) also includes a guide rail (39), a second threaded rod (40), a protective side plate (41), and a connecting block (42). The guide rail (39) is symmetrically fixed at both ends of the support frame (8). The connecting block (42) is slidably sleeved on the guide rail (39). The protective side plate (41) is fixedly installed at the bottom end of the connecting block (42) away from the guide rail (39). The second threaded rod (40) is threaded into the top end of the connecting block (42).

6. A leveling method using a concrete rolling leveling device, employing the concrete rolling leveling device described in any one of claims 1-5, characterized in that... It includes the following steps: S1. First, the collecting device (2) is fixedly installed on the external driving equipment. Then, the concrete is poured into the inside of the collecting device (2). The collecting device (2) is connected to the inside of the connecting pipe (24), so that the concrete can flow into the inside of the conveying cylinder (26). At this time, the third gear (35) can be connected to the motor shaft outside. Start the motor so that the third gear (35) can rotate. When the third gear (35) rotates, it can drive the second gear (25) and the spiral blade (27) to rotate at the same time, so that the concrete can be stably conveyed to the inside of the nozzle (29). The nozzle (29) is perpendicular to the ground, so that the concrete can be conveyed to the ground. S2. Then, start the drive equipment to move the whole device until the bottom of the vibrator (16) passes the top of the concrete so that the surface of the concrete can be leveled. At the same time, the hydraulic cylinder (10) can be turned on to drive the synchronous rod (11) to move down into the interior of the concrete, thereby preventing air bubbles from remaining in the interior of the concrete. S3. Finally, when the third gear (35) is rotating, the worm (13) can be driven to rotate on the top of the worm wheel (19) through the connecting shaft (34), so that the worm wheel (19) can drive the first gear (18) and the transmission belt (17) to rotate at the same time, so that the agitator (20) can push the excess concrete on the edge of the vibrator (16) to the front end, avoiding excessive accumulation of concrete on both sides of the vibrator (16).
