Description

Technical Field

[0001] The invention relates to the technical field of bridge construction equipment, and in particular to automatic concrete pouring equipment for bridge construction. Background Art

[0002] A bridge generally refers to a structure built across rivers, lakes, and the sea to enable vehicles and pedestrians to pass smoothly. To adapt to the modern high-speed development of the transportation industry, bridges are also extended to refer to buildings that are built across mountain streams, poor geology, or to meet other transportation needs to make travel more convenient. During the construction of a bridge, concrete needs to be poured so that the concrete becomes the main structure of the bridge after solidification.

[0003] The concrete pouring equipment for bridge construction in the prior art is convenient for adjusting the pouring height on the one hand, and for vibrating the poured concrete during pouring on the other hand, so as to discharge internal bubbles and eliminate the honeycomb surface of the concrete, so as to improve its strength after solidification. However, the existing concrete pouring equipment still has the following problems during use:

[0004] 1) When vibrating the poured concrete, the poured concrete is usually vibrated by a vibrating rod fixedly installed at one or more positions near the pouring pipe. However, due to the fixed position of the vibrating rod, the vibration range is small during the vibration process, resulting in a poor vibration effect at a position far away from the vibrating rod;

[0005] 2) When the mixing drum in the existing concrete pouring equipment stirs the concrete, it is only stirred by a single stirring structure, which makes it difficult to further improve the flow effect of the concrete during the mixing process. The stirring effect is poor, thereby prolonging the mixing time before concrete pouring and reducing the pouring efficiency;

[0006] In view of the above technical defects, a solution is now proposed. Summary of the invention

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] Embodiment 1:

[0045] In the process of concrete pouring and vibration of traditional pouring equipment, due to the fixed position of the vibrating rod, the vibration range is small during the vibration process, and the vibration effect is poor at the position far away from the vibrating rod. The following solutions can be used to solve this problem:

[0046] See also Figure 1-Figure 3 and Figure 5-Figure 9 As shown, in this embodiment, an automatic concrete pouring equipment for bridge construction includes a mounting frame 1, and a plurality of fixed ear plates are welded on the inner side wall of the mounting frame 1, which is used to install the equipment on an engineering vehicle. Support plates 11 are symmetrically welded on both sides of the top of the mounting frame 1, and a position adjustment mechanism 2 is arranged between the support plates 11, which is used to adjust the position of the pouring pipe 42 in the horizontal plane and the vertical plane according to the pouring position. The position adjustment mechanism 2 includes an L-shaped bracket 21, a lifting groove 22 and a lifting block 23. The vertical section of the L-shaped bracket 21 is provided with a lifting groove 22, and the lifting block 23 is slidably connected in the lifting groove 22. A fixed plate 3 is welded on one side of the lifting block 23. The fixed plate 3 is used to install the pouring mechanism 4, and is also used to install a deflection structure that drives the pouring mechanism 4 to rotate. The bottom of the fixed plate 3 is provided with the pouring mechanism 4, and a stirring mechanism 5 is arranged between the support plates 11;

[0047] The pouring mechanism 4 includes a mounting plate 41, a pouring tube 42, an annular guide rail 43, a movable plate 44 and a vibrating rod 45. A plurality of pouring tubes 42 are fixedly mounted on the mounting plate 41 for increasing the pouring efficiency of concrete. The bottom of the mounting plate 41 is located on the outside of the plurality of pouring tubes 42 and is fixedly mounted with an annular guide rail 43 for slidingly mounting a plurality of vibrating rods 45. A plurality of movable plates 44 are movably mounted at the bottom of the annular guide rail 43. The bottom of each movable plate 44 is detachably connected with a vibrating rod 45. This connection method is a bolt connection, which is easy to replace a damaged vibrating rod 45. A driving assembly 6 for driving each movable plate 44 to move is provided at the bottom of the mounting plate 41.

[0048] The pouring mechanism 4 further includes a guide groove 46, a rotating plate 47, an L-shaped rod 48, a roller 1 49 and a roller 2 410. The outer walls of both sides of the annular guide rail 43 are provided with guide grooves 46. The rotating plates 47 are symmetrically connected to the top of the movable plate 44. The tops of both ends of each rotating plate 47 are fixedly connected to an L-shaped rod 48. The lateral section of the L-shaped rod 48 is connected to a roller 1 49 that is connected to the corresponding guide groove 46 in a rolling manner. The guide groove 46 is connected to the roller 1 49 on the L-shaped rod 48 in a rolling manner to prevent the movable plate 4 from being moved. During the sliding process, the vertical section of the L-shaped rod 48 is rotatably connected to a second roller 410 that is rollingly connected to the outer side wall of the corresponding annular guide rail 43. The second roller 410 that is rotatably connected to the L-shaped rod 48 and the side wall of the annular guide rail 43 are rollingly connected, and the rotating plate 47 and the movable plate 44 are rotatably connected. When the movable plate 44 moves to the arc section on the annular guide rail 43, it is possible to avoid wear on the inner wall of the annular guide rail 43 and improve the sliding stability of the movable plate 44 during the entire movement process.

[0049] The driving assembly 6 includes a rotating shaft 61, a synchronous wheel 62, a synchronous belt 63, a driving ear plate 64 and a driving motor 65. The two sides of the bottom of the mounting plate 41 are symmetrically connected to the rotating shaft 61, and the ends of the rotating shaft 61 are fixedly connected to the synchronous wheel 62. The synchronous wheel 62 is connected to the synchronous belt 63 on its periphery. The connection between the synchronous belt 63 and the synchronous wheel 62 can effectively avoid the problem of transmission slippage between the belt and the wheel. A driven ear plate 411 is fixedly connected to one side of the movable plate 44, and a fixing pin 412 is fixedly connected to the driven ear plate 411. A driving ear plate 64 that is plugged into the corresponding fixing pin 412 is fixedly connected to the outer wall of the synchronous belt 63. By plugging the fixing pin 412 on the movable plate 44 into the driving ear plate 64, the synchronous belt 63 can drive the movable plate 44 to slide on the annular guide rail 43, thereby realizing a large-scale vibration of the vibrating rod 45 in the concrete, thereby avoiding the problem of uneven vibration in different areas caused by the vibrating rod 45 being fixed in a certain position in the prior art. The top bolt of the mounting plate 41 is connected to a driving motor 65 for driving the corresponding rotating shaft 61 to rotate.

[0050] The position adjustment mechanism 2 also includes a slide plate 24, a sliding block 25, a rotating shaft 26, a sprocket 27, a chain 28, a rotating motor 1 29, a screw 210 and a rotating motor 211. The slide plate 24 is fixedly connected to the bottom of one side between the support plates 11. The slide plate 24 is slidably connected to the sliding block 25 fixedly connected to the L-shaped bracket 21 to achieve the horizontal sliding of the L-shaped bracket 21. The two ends of the slide plate 24 away from the L-shaped bracket 21 are symmetrically rotatably connected to the rotating shaft 26. The rotating shaft 26 is fixedly connected to the sprocket 27. The sprocket 27 is connected to the chain 28 on its periphery through the transmission connection. The sliding block 25 is fixedly connected to the chain 28 on one side of the sprocket 27. The free ends of the two ends of the chain 28 are connected through two sprockets 27. After being guided, it is fixedly connected with both sides of the sliding block 25. A through groove for the chain 28 to penetrate is opened on the sliding block 25 on the other side of the sprocket 27, so that when the sprocket 27 drives the chain 28 to rotate, it drives the sliding block 25 to slide on the slide plate 24, so as to adjust the horizontal position of the casting pipe 42. A rotating motor 29 for driving the corresponding rotating shaft 26 to rotate is bolted on the slide plate 24. A screw rod 210 threadedly connected to the lifting block 23 is rotatably connected in the lifting groove 22. The lifting block 23 is driven to slide up and down in the lifting groove 22 by the rotation of the screw rod 210, so as to adjust the vertical position of the casting pipe 42. A rotating motor 211 for driving the screw rod 210 to rotate is bolted on the L-shaped bracket 21.

[0051] Embodiment 2:

[0052] The following solutions can be used to solve the problem that it is difficult to adaptively adjust the width of the vibrating rod's motion range and thus cannot be applied to bridge casting sites of different widths:

[0053] See also Figure 5 As shown, in this embodiment, a rotating shaft 31 rotatably connected to the end of the fixed plate 3 is welded at the top center of the mounting plate 41, which is used to realize the rotation of the mounting plate 41, and the length of the rotating shaft 31 can be extended to vibrate the concrete with a deeper pouring depth. The top of the rotating shaft 31 is fixedly connected to a support plate 32, and the top of the free end of the support plate 32 is fixedly connected to a vertical rod 1 33. The top of the fixed plate 3 on one side close to the lifting block 23 is fixedly connected to a vertical rod 2 34, and an electric push rod 35 is hinged between the vertical rod 1 33 and the vertical rod 2 34. The piston rod of the electric push rod 35 is telescopically coordinated with the support plate 32 to drive the mounting plate 41 to rotate, so that the pouring width in the moving direction along the length of the slide plate 24 and the width of the moving range of the vibrating rod 45 can be adaptively adjusted, and can be better applied to bridge pouring sites of different widths.

[0054] Embodiment three:

[0055] When mixing concrete with existing pouring equipment, it is difficult to further improve the flow effect of concrete during the mixing process by only mixing with a single mixing structure. The problem of poor mixing effect can be solved by the following solutions:

[0056] See also Figure 3 and Figure 4 As shown, in this embodiment, the stirring mechanism 5 includes a rotating rod 51, a stirring drum 52, a stirring protrusion 53 and a stirring motor 54. The rotating rod 51 is rotatably connected between the tops of the support plates 11.

A connecting sleeve 13 rotatably connected to the open ends of the two groups of stirring drums 52 is welded on the top of the mounting frame 1 through a support column 12. The connecting sleeve 13 is used to connect the two groups of stirring drums 52, and to connect the injection pipe 14 and the discharge pipe 15, while preventing the two from rotating with the stirring drum 52, causing the problem that the pouring pipe 42 cannot be connected to the discharge pipe 15 through the conveying connecting pipe. 1. The axis lines of the mixing drum 52 and the connecting sleeve 13 are all arranged to coincide with each other, so that the mixing drum 52 can rotate stably during the rotation of the rotating rod 51. The top and bottom of the connecting sleeve 13 are respectively fixedly connected with the injection pipe 14 and the discharge pipe 15. The discharge pipe 15 is provided with a valve to prevent the outflow of concrete during the mixing process. The inner wall of the mixing drum 52 is fixedly connected with a plurality of mixing protrusions 53 distributed in a circular array relative to its axis. During the rotation of the mixing drum 52, the mixing protrusions 53 on the inner wall cooperate to stir and turn the concrete. The support plate 11 is bolted with a mixing motor 54 for driving the rotating rod 51 to rotate.

[0057] The stirring mechanism 5 also includes a stirring rod 55, a stirring plate 56 and a gear 57. A plurality of stirring rods 55 distributed in a ring array relative to the rotating rod 51 are rotatably connected between the inner walls of the two groups of stirring drums 52. A plurality of stirring plates 56 are fixedly connected to the outer wall of the stirring rod 55. The stirring drum 52 drives the stirring rod 55 and the stirring plate 56 to revolve during the rotation process, thereby improving the stirring effect of the concrete. One end of the stirring rod 55 penetrates the outer side of the corresponding stirring drum 52 and is fixedly connected to the gear 57. A gear ring 16 meshing with the gear 57 is fixedly connected to the inner wall of the support plate 11. The gear 57 on the stirring rod 55 cooperates with the gear ring 16 on the support plate 11, so that the stirring rod 55 rotates while revolving, thereby further improving the stirring effect of the concrete.

[0061] Step 2: Position adjustment of the pouring pipe 42: Start the rotating motor 1 29 to drive the chain 28 to rotate through the sprocket 27, and the chain 28 drives the L-shaped bracket 21 to slide through the sliding block 25 to adjust the position of the pouring pipe 42 on the horizontal plane, start the rotating motor 211 to drive the screw rod 210 to rotate, and the screw rod 210 drives the fixed plate 3 to move through the lifting block 23, thereby adjusting the height of the pouring pipe 42;

[0062] Step 3: Concrete pouring: Connect the discharge pipe 15 to the pouring pipe 42 through the delivery connection pipe, and use the concrete delivery pump to deliver the concrete in the mixing drum 52 to the pouring pipe 42 for pouring;

The synchronous wheel 62 drives the multiple movable plates 44 to slide on the annular guide rail 43 at the same time through the synchronous belt 63, driving the vibrating rod 45 to vibrate in a large range in the concrete;

[0064] Step 5: Adjust the width of the movement range of the vibration rod 45: Start the piston rod of the electric push rod 35 to extend and retract, and cooperate with the support plate 32 to drive the mounting plate 41 to rotate, so as to adaptively adjust the casting width in the movement direction along the length of the slide plate 24 and the width of the movement range of the vibration rod 45.
