Description

Technical Field

[0001] This invention relates to the field of building construction technology, and in particular to a concrete pouring equipment for building structures. Background Technology

[0002] Concrete pouring equipment is a device used to pour concrete for the main structure of a building during construction. It is widely used in the construction industry. Existing concrete pouring equipment includes a pump truck mechanism and an output hose. The pump truck mechanism is equipped with a material conveying assembly, a power assembly, and a pump pipe assembly. The input end of the output hose is connected to the output end of the pump pipe assembly. When using existing concrete pouring equipment, the concrete mixer truck first feeds the prepared concrete into the material conveying assembly. Then, the concrete in the material conveying assembly is pumped into the pump pipe assembly by the power assembly. Finally, the pump pipe assembly feeds the concrete into the output hose. At this point, the construction worker controls the output direction of the output hose so that the concrete in the output hose falls into the designated steel reinforcement slot.

[0003] Currently, during the use of concrete pouring equipment, the pouring hose is quite heavy, which requires a lot of physical labor for construction workers when moving the hose. In addition, the effective control over the area where the pouring hose can be moved limits the pouring range. Summary of the Invention

[0015] The beneficial effects of this invention are:

[0016] (1) By setting up a discharge assembly, concrete enters the discharge vertical pipe through the feeding pipe, then flows into the discharge horizontal pipe, and is discharged outward through the extension pipe. During this process, the first cylinder drives the first shaft to move up and down, and the second cylinder drives the second shaft to move linearly. The first shaft and the second shaft are used to clear the concrete conveying process and prevent the concrete from getting blocked during discharge. At the same time, the first shaft will drive the lifting rod to move up and down synchronously. By using the sliding cooperation between the sliding pin and the curved closed ring groove, the lifting rod will drive the shaft cylinder to deflect back and forth, thereby realizing the reciprocating swing process of the discharge horizontal pipe. When the second shaft moves linearly, it will drive the extension pipe to slide back and forth along the axis of the discharge horizontal pipe, thereby adjusting the discharge radius when the concrete is discharged. Combined with the reciprocating swing process of the discharge horizontal pipe, the area of ​​concrete pouring is effectively increased, and the pouring efficiency is greatly improved.

[0017] (2) By setting up a lifting component, after the dual-axis motor starts, it will drive the drive shaft to rotate. The drive shaft will drive the transmission shaft to rotate through the transmission belt. The transmission shaft will drive the first gear to rotate together. The first gear will drive the second gear to rotate synchronously. The second gear will drive the synchronous shaft to achieve the synchronous rotation process with the drive shaft. Thus, the two sets of winding rollers on the drive shaft and the synchronous shaft will rotate synchronously, thereby realizing the unwinding or winding process of the pull rope. As the pull rope drives the discharge vertical pipe to be lifted upward or lowered downward through the fixed frame, the pouring height can be adjusted according to the aggregate coarseness of the concrete, avoiding the situation where the coarse aggregate settles and segregates due to the excessively high concrete pouring point.

[0018] (3) By setting up a scraper assembly, during the concrete pouring process, the entire device will move forward along the pouring area via the traveling wheels. During this process, the movable scraper and the fixed scraper will be able to scrape the pouring surface. When the third cylinder is started, the third cylinder will drive the movable scraper to move up and down along the limit rod. With the help of the distance sensor, the lifting distance data of the movable scraper can be monitored, so that the scraping thickness of the concrete surface can be accurately adjusted. At the same time, during the process, due to the separate design of the movable scraper and the fixed scraper, and the movable scraper and the fixed scraper are set close to each other, the two move relative to each other during the lifting and adjustment of the movable scraper. The fixed scraper will be able to scrape off the concrete residue remaining on the movable scraper, making its surface smooth and flat, effectively improving the scraping treatment effect.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1 and Figure 2 As shown, the present invention is a concrete pouring equipment for building construction, including a base plate 1 and a top plate 2. The base plate 1 and the top plate 2 are fixedly connected by a fixing rod 3. The four corners of the bottom of the base plate 1 are provided with traveling wheels 101. A mixing drum 4 is fixedly installed on the top plate 2. A feeding drum 5 is fixedly installed at the bottom of the top plate 2 by a mounting frame 201. The bottom of the mixing drum 4 is connected to the feeding drum 5 through a discharge pipe 403. A feeding pipe 503 is provided at the discharge end of the feeding drum 5. A lifting assembly 7 is provided at the upper end of the top plate 2. The lifting assembly 7 is connected to a discharge assembly 6. A scraping assembly 8 is provided on the base plate 1.

[0032] The mixing drum 4 is equipped with a mixing motor 402 fixedly mounted at its top. A spiral mixing rod 401 is installed inside the mixing drum 4, and the output end of the mixing motor 402 is fixedly connected to the spiral mixing rod 401. A feeding motor 502 is fixedly mounted at one end of the feeding drum 5, and a feeding auger 501 is installed inside the feeding drum 5 along its axial direction. The output end of the feeding motor 502 is fixedly connected to the feeding auger 501. During operation, concrete is added to the mixing drum 4. The mixing motor 402 drives the spiral mixing rod 401 to thoroughly and evenly mix the concrete. The evenly mixed concrete enters the feeding drum 5 through the discharge pipe 403. The feeding motor 502 then drives the feeding auger 501 to rotate, thus gradually pushing the concrete forward along its axial direction and discharging it through the feeding pipe 503 into the discharge assembly 6.

[0033] like Figures 3-6 As shown, the discharge assembly 6 includes a discharge vertical pipe 61, a discharge horizontal pipe 62, and an extension pipe 63. The feeding pipe 503 is connected to the discharge vertical pipe 61. A first cylinder 64 is fixedly installed at the top of the discharge vertical pipe 61. A first shaft 611 is installed inside the discharge vertical pipe 61 along the axial direction. The output end of the first cylinder 64 is fixedly connected to the first shaft 611. A lifting rod 612 is fixedly installed at the bottom of the first shaft 611. A sliding pin 6121 is fixedly installed on one side of the lifting rod 612. The bottom end of the discharge vertical pipe 61 is rotatably engaged with the upper end of the discharge horizontal pipe 62, and the discharge vertical pipe 61 is connected to the discharge horizontal pipe 62. A shaft cylinder 621 is fixedly installed inside the upper end of the discharge horizontal pipe 62. The bottom of the first shaft 611... A return spring 613 is provided between the part and the top of the shaft cylinder 621. The lifting rod 612 is slidably installed inside the shaft cylinder 621. A curved closed annular groove 6211 is provided on the inner wall of the shaft cylinder 621. The sliding pin 6121 is adapted to be slidably installed in the curved closed annular groove 6211. A second cylinder 65 is fixedly installed at one end of the discharge horizontal pipe 62. An extension pipe 63 is slidably sleeved and installed at the other end of the discharge horizontal pipe 62. A fixing plate 631 is fixedly installed on the inner wall of the extension pipe 63. The output end of the second cylinder 65 is fixedly connected to the fixing plate 631. A second shaft 652 is fixedly installed on the fixing plate 631. The second shaft 652 slides through the discharge horizontal pipe 62 along the axial direction and is fixedly connected to the fixing plate 631.

[0034] Specifically, by setting up the discharge assembly 6, concrete enters the discharge vertical pipe 61 through the feeding pipe 503, then flows into the discharge horizontal pipe 62, and is discharged outward through the extension pipe 63. During this process, the first cylinder 64 drives the first shaft 611 to move up and down, and the second cylinder 65 drives the second shaft 652 to move linearly. The first shaft 611 and the second shaft 652 are used to clear the concrete conveying process and prevent blockage during discharge. At the same time, the first shaft 611 will drive the lifting rod 612 to move in the same direction. The lifting rod 612 moves up and down, and by utilizing the sliding engagement between the sliding pin 6121 and the curved closed annular groove 6211, the lifting rod 612 will drive the shaft cylinder 621 to deflect back and forth, thereby realizing the reciprocating swing process of the discharge horizontal pipe 62. When the second shaft 652 moves in a straight line, it will drive the extension pipe 63 to slide back and forth along the axis of the discharge horizontal pipe 62, thereby adjusting the discharge radius when the concrete is discharged. Combined with the reciprocating swing process of the discharge horizontal pipe 62, the area of ​​concrete pouring is effectively increased, and the pouring efficiency is greatly improved.

[0035] like Figure 4 As shown, a lifting chute 614 is provided through one side of the discharge vertical pipe 61. The feeding pipe 503 is adapted to slide and install in the lifting chute 614. A backing plate 504 is provided extending from the edge of the opening of the feeding pipe 503. The backing plate 504 is abutted against the inner wall of the discharge vertical pipe 61, and the backing plate 504 always closes the lifting chute 614.

[0036] Specifically, when adjusting the height of the discharge vertical pipe 61 using the lifting assembly 7, the feeding pipe 503 will always remain sliding within the lifting chute 614. During this process, the abutment plate 504 will always be tightly attached to the inner wall of the discharge vertical pipe 61 and seal the lifting chute 614. This not only ensures that the discharge vertical pipe 61 can smoothly transport concrete during the lifting and adjustment process, but also ensures a good sealing effect by using the sealing effect of the abutment plate 504 on the lifting chute 614, preventing concrete from leaking out of the lifting chute 614.

[0037] like Figure 4 and Figure 5 As shown, the bottom outer wall of the discharge vertical pipe 61 is provided with a mating groove 615, and the inner wall of the upper end of the discharge horizontal pipe 62 is provided with a mating ring protrusion 623. The mating ring protrusion 623 and the mating groove 615 are rotatably mated.

[0038] Specifically, by setting the mating groove 615 and the mating ring protrusion 623, when the lifting rod 612 drives the shaft cylinder 621 to rotate through the sliding pin 6121, the discharge horizontal tube 62 will rotate along the mating groove 615 through the mating ring protrusion 623, which helps to improve the stability of the discharge horizontal tube 62 during the deflection process.

[0039] like Figure 6As shown, limit blocks 622 are evenly arranged on the outer wall of the discharge horizontal pipe 62 along the axial direction, and limit grooves 632 are evenly arranged on the inner wall of the extension pipe 63 along the axial direction. The limit blocks 622 are adapted to slide and install in the corresponding limit grooves 632.

[0040] Specifically, by setting a limiting block 622 and a limiting groove 632, when the second cylinder 65 drives the extension tube 63 to slide back and forth through the second shaft 652, the limiting block 622 will always slide within the limiting groove 632, effectively ensuring the stability of the extension tube 63 during linear sliding. At the same time, by using the constraint and limiting effect of the limiting block 622, the extension tube 63 can only move along the axial direction, avoiding unnecessary rotation.

[0041] like Figure 7 and Figure 8 As shown, the lifting assembly 7 includes a dual-axis motor 701. The output end of the dual-axis motor 701 is provided with a drive shaft 702. Both ends of the drive shaft 702 are connected to the transmission shaft 703 via a transmission belt 704. A first gear 706 is sleeved on the transmission shaft 703. The first gear 706 meshes with a second gear 707. The second gear 707 is sleeved on a synchronous shaft 705. Both ends of the drive shaft 702 and the synchronous shaft 705 are provided with winding rollers 708. A pull rope 709 is wound on the winding rollers 708. The bottom end of the pull rope 709 passes through the top plate 2 and is fixedly connected to the fixing frame 710. The fixing frame 710 is fixedly installed on the outside of the discharge vertical pipe 61.

[0042] Furthermore, guide rods 711 are fixedly installed on both sides of the fixed frame 710. The top of the guide rods 711 slides through the top plate 2, and a clearance opening 202 for the discharge vertical pipe 61 to pass through is provided on the top plate 2.

[0043] Furthermore, by setting up the lifting component 7, after the dual-axis motor 701 is started, it will drive the drive shaft 702 to rotate. The drive shaft 702 will drive the transmission shaft 703 to rotate through the transmission belt 704. The transmission shaft 703 will drive the first gear 706 to rotate together. The first gear 706 will drive the second gear 707 to rotate synchronously. The second gear 707 will drive the synchronous shaft 705 to achieve synchronous rotation with the drive shaft 702. This will cause the two sets of winding rollers 708 on the drive shaft 702 and the synchronous shaft 705 to rotate synchronously, thereby realizing the unwinding or winding process of the pull rope 709. As the pull rope 709 drives the discharge vertical pipe 61 to be lifted upward or lowered downward through the fixed frame 710, the pouring height can be adjusted according to the coarseness of the concrete aggregate, avoiding the situation where the coarse aggregate settles and segregates due to the concrete pouring point being too high.

[0044] It is important to note that, in order to ensure the balance and stability of the discharge vertical pipe 61 during height adjustment, a guide rod 711 is used to limit and guide it. During the lifting and adjustment process, the discharge vertical pipe 61 will always move along the vertical sliding and penetrating direction of the guide rod 711. At the same time, the clearance opening 202 can provide sufficient space for the movement of the discharge vertical pipe 61, ensuring that the discharge vertical pipe 61 avoids collision with the top plate 2 during the lifting and adjustment process.

[0045] like Figure 9 As shown, the scraping assembly 8 includes a movable scraper 801 and a fixed scraper 802. The top of the fixed scraper 802 is fixedly disposed at the bottom end of the base plate 1. The movable scraper 801 is slidably disposed against one side of the fixed scraper 802. A third cylinder 803 is fixedly disposed at the upper end of the base plate 1. The output end of the third cylinder 803 is fixedly connected to the top end of the movable scraper 801. Limiting rods 805 are fixedly disposed on both sides of the upper end of the movable scraper 801. The limiting rods 805 slide through the base plate 1. A buffer spring 806 is disposed between the base plate 1 and the movable scraper 801. A distance sensor 804 is disposed at the upper end of the movable scraper 801.

[0046] Furthermore, a limiting groove 8011 is provided on one side of the fixed scraper 802, and a limiting slider 8021 is provided on one side of the movable scraper 801. The limiting slider 8021 is adapted to slide within the limiting groove 8011.

[0047] Specifically, by setting up the scraper assembly 8, during the concrete pouring process, the entire device will move forward along the pouring area via the traveling wheels 101. During this process, the movable scraper 801 and the fixed scraper 802 can level the pouring surface. When the third cylinder 803 is activated, the third cylinder 803 will drive the movable scraper 801 to move up and down along the limit rod 805. With the help of the distance sensor 804, the lifting distance data of the movable scraper 801 can be monitored, thereby enabling precise adjustment of the leveling thickness of the concrete surface. At the same time, due to the separate design of the movable scraper 801 and the fixed scraper 802, and the movable scraper 801 and the fixed scraper 802 being set close to each other, the two move relative to each other during the lifting and adjustment process of the movable scraper 801. The fixed scraper 802 can scrape off the concrete residue remaining on the movable scraper 801, making its surface smooth and flat, effectively improving the leveling effect.

[0048] The working principle of this invention is as follows: Figures 1-9As shown, during use, concrete is first added to the mixing drum 4. The mixing motor 402 drives the spiral mixing rod 401 to thoroughly and evenly mix the concrete. The evenly mixed concrete enters the feeding drum 5 through the discharge pipe 403. Then, the feeding motor 502 drives the feeding auger 501 to rotate, thereby gradually pushing the concrete forward along the axial direction and entering the discharge assembly 6 through the feeding pipe 503 for discharge. The concrete enters the discharge vertical pipe 61 through the feeding pipe 503, then flows into the discharge horizontal pipe 62, and is discharged outward through the extension pipe 63. During this process, the first cylinder 64 drives the first shaft 611 to move up and down, and the second cylinder 65 drives the second shaft 652 to move linearly. The first shaft 611 and the second shaft 652 are used to clear the concrete conveying process and prevent blockage during discharge. At the same time, the first shaft 611 drives the lifting rod 612 to move up and down synchronously. By using the sliding engagement of the sliding pin 6121 and the curved closed annular groove 6211, the lifting rod 612 will drive the shaft cylinder 621 to deflect back and forth, thereby realizing the reciprocating swing process of the discharge horizontal pipe 62. When the second shaft 652 moves in a straight line, it will drive the extension pipe 63 to slide back and forth along the axial direction of the discharge horizontal pipe 62, thereby adjusting the discharge radius when the concrete is discharged. Combined with the reciprocating swing process of the discharge horizontal pipe 62, the area of ​​concrete pouring is effectively increased, and the pouring efficiency is greatly improved. During the concrete pouring process, the entire device moves forward along the pouring area via the wheels 101. During this process, the movable scraper 801 and the fixed scraper 802 can level the pouring surface. When the third cylinder 803 is activated, it drives the movable scraper 801 to move up and down along the limit rod 805. The distance sensor 804 monitors the lifting distance of the movable scraper 801, thereby allowing for precise adjustment of the leveling thickness of the concrete surface. Simultaneously, due to the separate design of the movable scraper 801 and the fixed scraper 802, and their close proximity, the movable scraper 801 moves relative to the fixed scraper 802 during the lifting and adjustment process. The fixed scraper 802 can then scrape away any remaining concrete residue on the movable scraper 801, making its surface smooth and flat, effectively improving the leveling effect.

[0049] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
