Traditional construction methods generally use manual insertion vibration, which relies heavily on the experience of the construction workers and may result in over-vibration (i.e., vibration time is too long) or incomplete vibration leading to local omissions and errors. This results in inconsistent construction quality, a poor construction environment, and high labor intensity.

[0003] As a result, some vibration equipment has emerged on the market, which can achieve automated vibration of the top slab of box girders, thereby improving the consistency of construction quality and reducing the labor intensity of construction workers. However, its vibration effect on the web of box girders is limited.

[0004] The web of a box girder typically contains steel strands, and the embedding depth of these strands varies with the size of the box girder. As the most important load-bearing part of the box girder, it should be vibrated most effectively to ensure quality. Existing automated vibration equipment cannot meet these requirements.

[0030] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Figures 1 to 5 This illustration shows an embodiment of the box girder vibration compaction device of the present invention. The device includes a first vibration assembly 2 for vibrating the top slab 11 of the box girder 1, a second vibration assembly 3 for vibrating the web 12 of the box girder 1, a guide rail assembly 4 arranged along a first direction, and a first movable seat 5 movably disposed on the guide rail assembly 4. The guide rail assembly 4 has second movable seats 6 at both ends that can move along a second direction perpendicular to the first direction. The first movable seat 5 is equipped with a lifting mechanism 7 for driving the first vibration assembly 2 to rise and fall, and a telescopic drive assembly 8 for driving the second vibration assembly 3 to extend and retract. The first direction is the width direction or transverse direction of the box girder 1, the second direction is the length direction or longitudinal direction of the box girder 1, and the third direction is the height direction or vertical direction of the box girder 1.

[0032] The box girder vibration device of this embodiment includes a first vibration assembly 2 for vibrating the top plate 11 of the box girder 1, and a second vibration assembly 3 for vibrating the web plate 12 of the box girder 1. The first movable seat 5 can drive the first vibration assembly 2 and others to move along the guide rail assembly 4, so that the vibration range can cover the transverse direction of the box girder 1 (see details). Figure 5 Because the guide rail assembly 4 has a sufficient span, it can also vibrate multiple box girders 1 arranged in the transverse direction in sequence. The second moving seat 6 can drive the guide rail assembly 4, the first moving seat 5, the first vibrating assembly 2, and the second vibrating assembly 3 to move longitudinally as a whole, so that the vibration range can cover the longitudinal direction of the box girder 1 and the vibration range is comprehensive. The telescopic drive assembly 8 can drive the second vibrating assembly 3 to extend and retract along the web 12, so that the second vibrating assembly 3 can always act on the position where the steel strands 13 are set on the web 12, ensuring the construction quality of this area and thus improving the consistency of the construction quality of the box girder 1.

[0033] See details Figure 3 and Figure 4 In this embodiment, the first movable seat 5 is also provided with an angle adjustment mechanism 9 for adjusting the tilt angle of the second vibrating assembly 3 in a third direction, which is perpendicular to the first and second directions. By adjusting the tilt angle or orientation of the second vibrating assembly 3 through the angle adjustment mechanism 9, it can adapt to different angles of the web plate 12, further improving the applicability of the equipment.

[0034] Further, in this embodiment, the telescopic drive assembly 8 includes a telescopic drive member 81, which is disposed on opposite sides of the first movable seat 5 along the first direction and hinged to the first movable seat 5. The angle adjustment mechanism 9 includes an adjustable rod 91, one end of which is rotatably connected to the telescopic drive member 81 (e.g., hinged to the telescopic drive member 81), and the other end of which is rotatably connected to the first movable seat 5 (e.g., hinged to the first movable seat 5). Preferably, the second vibration assembly 3 includes a second vibrating rod 31, which is connected to the telescopic drive member 81 in a one-to-one correspondence. As the adjusting rod 91 extends and retracts, it can drive the telescopic drive member 81 to rotate, that is, adjust the tilt angle of the telescopic drive member 81, thereby achieving the purpose of adjusting the tilt angle of the second vibrating rod 31 so that it is basically consistent with the tilt angle of the web 12; while the telescopic drive member 81 can drive the second vibrating rod 31 to extend and retract, so that the second vibrating rod 31 can always act on the position where the steel strand 13 is set on the web 12, ensuring the construction quality of this area. Preferably, the telescopic drive component 81 is a hydraulic cylinder, and the second vibrating rod 31 is connected to the piston rod of the hydraulic cylinder. Of course, in other embodiments, the telescopic drive component 81 can also be a pneumatic cylinder, an electric cylinder, a gear and rack mechanism, etc., which will not be described in detail here. The adjusting rod 91 includes an adjusting tube and rods threadedly connected to both ends of the adjusting tube. As the adjusting tube rotates, the rods at both ends can be extended or retracted, thereby achieving the purpose of changing the overall length of the adjusting rod 91. The structure is simple, the adjustment is convenient, and it has a self-locking function.

[0035] Furthermore, in this embodiment, a vibration isolation member 82 (specifically between the second vibrating rod 31 and the telescopic drive member 81) is provided between the telescopic drive assembly 8 and the second vibrating assembly 3, which helps to reduce the vibration transmitted from the second vibrating rod 31 to the telescopic drive member 81 and avoid damage to the telescopic drive member 81.

[0036] As a preferred embodiment, the vibration isolation member 82 is a flexible vibration isolation member (for example, it can be a rubber material or other composite material). On the one hand, it can maintain the determined orientation and angle of the second vibrating rod 31, and on the other hand, it retains a certain adaptive adjustment capability. When the second vibrating rod 31 contacts the steel cage of the box girder 1, it can automatically shift and avoid it. The structure is reasonable and effective.

[0037] See details Figure 3 and Figure 4In this embodiment, the lifting mechanism 7 includes a lifting bracket 71 and a lifting drive component 72. The lifting drive component 72 is connected to the lifting bracket 71 to drive the lifting bracket 71 to move along a third direction perpendicular to the first and second directions. The first vibration component 2 is disposed on the lifting bracket 71. The lifting drive component 72 can drive the lifting bracket 71 and the first vibration component 2 on it to rise and fall, so that the first vibration component 2 can be inserted into the top plate 11 of the box girder 1 for vibration or separated from the top plate 11. Preferably, the telescopic drive component 81 is a hydraulic cylinder, and the lifting bracket 71 is connected to the piston rod of the hydraulic cylinder. Of course, in other embodiments, the telescopic drive component 81 can also be a pneumatic cylinder, an electric cylinder, a gear and rack mechanism, etc., which will not be described in detail. The first vibration component 2 includes multiple first vibration rods, which are distributed in a matrix, and can vibrate a rectangular area of ​​a certain size on the top plate 11 to improve the vibration efficiency.

[0038] Furthermore, in this embodiment, a guide assembly 51 is provided between the first movable seat 5 and the lifting bracket 71. The guide assembly 51 includes a guide tube 511 and an insert tube 512 that can move relative to each other in a third direction and are interlocked. Preferably, two guide tubes 511 and two insert tubes 512 are provided and interlocked one-to-one, which can play a good guiding role and prevent the lifting bracket 71 from deviating or shaking during lifting and lowering movements. The structure is simple and reliable. Preferably, both the guide tube 511 and the insert tube 512 are made of square tubing. Of course, in other embodiments, the guide assembly 51 may also include a lifting guide rail, a guide groove, etc., and the lifting bracket 71 may be provided with sliders and rollers that cooperate with the lifting guide rail and the guide groove, which can also play a good guiding role, and will not be described in detail here.

[0039] See details Figure 1 and Figure 2 In this embodiment, the guide rail assembly 4 includes a truss beam 41 and a guide rail 42 disposed on the truss beam 41, with the first movable seat 5 disposed on the guide rail 42. The truss beam 41, with its high strength and good mechanical properties, allows for a large span while maintaining a small size, thus reducing space requirements. The guide rail 42 provides guidance for the first movable seat 5, ensuring the stability of its lateral movement, preventing offset and swaying, and reducing motion resistance. The structure is simple and reliable.

[0040] Furthermore, in this embodiment, the truss beam 41 is provided with limiting members 43 at both ends, the guide rail 42 is located between the two limiting members 43, and the first movable seat 5 is provided with a buffer member 52 for abutting against the limiting members 43. The limiting members 43 are used to limit the extreme position of the lateral movement of the first movable seat 5 to prevent it from disengaging from the guide rail 42; the buffer member 52 is used to provide cushioning to prevent the first movable seat 5 from rigidly colliding with the limiting members 43, thereby further improving reliability. Among them, the limiting members 43 can be, for example, limiting plates, limiting blocks, etc., and the buffer member 52 can be, for example, buffer springs, rubber blocks, etc.

[0041] Furthermore, in this embodiment, the first movable seat 5 is provided with a drive gear 53, and the truss beam 41 is provided with a rack 44. The drive gear 53 meshes with the rack 44, and the rack 44 is arranged parallel to the guide rail 42. When the drive gear 53 rotates, it can move along the rack 44, thereby driving the first movable seat 5 to move along the guide rail 42. Using a gear and rack drive can achieve high positioning accuracy and reliable transmission. Of course, in other embodiments, the rack 44 can also be provided on the guide rail 42; a hydraulic cylinder, sprocket and chain mechanism, etc., can also be used to drive the first movable seat 5 to reciprocate. The specific structure of the second movable seat 6 can refer to the first movable seat 5, and will not be described again.

[0042] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention.
