Description

Technical Field

[0001] This invention relates to the field of gap reinforcement structure technology, specifically to an adjustable reinforcement structure for splicing gaps in modular bridges. Background Technology

[0002] Modular bridges are a modern bridge construction method that involves assembling and splicing multiple bridge building modules together to achieve rapid bridge construction. Traditional modular bridges, however, leave gaps between each module during construction, necessitating reinforcement to enhance the bridge's strength.

[0003] A Chinese patent application with publication number CN118668565A discloses a structure for reinforcing longitudinal cracks in bridge and tunnel pavements. The structure includes a main body with a push handle fixedly connected to its tail. A vertically moving component is mounted on the main body, and a mounting plate is slidably connected to the inner wall of the component. A hydraulic telescopic rod is installed inside the component, with its top connected to the mounting plate. A mixing tank is mounted on the mounting plate. In this invention, when a motor drives a rotating rod to rotate, a transmission rod also drives a mixing shaft to rotate, thus thoroughly mixing the slurry in the mixing tank. Simultaneously, the transmission rod heats the slurry in the mixing tank through a heat pipe, ensuring the slurry has sufficient fluidity to repair vertical cracks.

[0004] However, this bridge gap reinforcement structure has the following drawbacks in practical use: 1. Existing bridge joint reinforcement structures typically involve pouring the mixed material (bridge curing material) into the joint to reinforce the bridge module. However, in practice, this method requires multiple drive components to operate, including material mixing, device movement, and material mixing within the joint. This results in significant noise and vibration during device operation, leading to poor stability during bridge construction. 2. Existing bridge joint reinforcement structures typically involve filling the gaps between bridge structural modules with reinforcement material to ensure the stability of the assembled modules. However, when this material is filled into the gaps, a large number of air bubbles accumulate inside, affecting the curing effect on bridge cracks and the overall strength of the bridge after construction. Summary of the Invention

[0027] The intermediate shaft passes through the partition, and the partition is installed on the inner side of the mounting bracket;

[0028] The system includes two movable gears that mesh with each other. Both gears are movably mounted at the bottom of the partition. A longitudinal shaft is internally connected to the other movable gear and movably connected to the top of the base.

[0029] The outer side of the longitudinal shaft is connected to the inner side of another transmission belt via a keyed synchronous pulley.

[0030] In a preferred embodiment of the present invention, an upper gear is mounted on the top of the intermediate shaft, and two upper gears are provided, both of which are rotatably connected to the top of the mounting bracket.

[0041] Compared with existing technologies, one or more of the above technical solutions have the following beneficial effects: 1. In the adjustable reinforcement structure for modular bridge joints, when the curing material is stirred to ensure its fluidity, the rotational force of the stirring material simultaneously drives two rollers to rotate. This allows the reinforcement structure to move and travel automatically while stirring, achieving efficient bridge joint reinforcement. Simultaneously, the rotational force of the stirring material can be adjusted to drive the mixing rollers to agitate the reinforcement material filling the joints, ensuring that there are no large gaps inside the reinforcement material. This improves the toughness and strength of the reinforcement material after solidification, thus guaranteeing the quality of the bridge after construction. Furthermore, the above operations can be driven by a single motor, effectively reducing vibration and noise in the reinforcement structure and increasing the stability of the bridge during construction. 2. In the adjustable reinforcement structure for modular bridge splice gaps, when the drive motor rotates the stirring shaft and multiple stirring blades to stir the material inside the box, the rotational force of the stirring shaft can simultaneously drive the pushing blades installed on its outer side to rotate, automatically pushing the reinforcement material at the bottom of the box, ensuring that the material in each position of the box can be moved to one side of the extraction pipe. At the same time, the above operation ensures that the extraction pipe discharges the material more evenly, reducing the probability of overfilling or underfilling when filling the gaps, and improving the filling and reinforcement effect of the gaps. 3. In the adjustable reinforcement structure for modular bridge splice joints, when agitating the reinforcement material filling the bridge joints, the mixing rod and mixing roller, which perform the agitation operation, can be moved to a certain position by the operation of a telescopic cylinder. This allows the mixing roller to be positioned in the middle of the joint, resulting in more uniform agitation of the reinforcement material inside the joint. Simultaneously, the height of the mixing roller can be raised and lowered by the operation of a hydraulic cylinder, allowing for agitation of the reinforcement material in joints of different depths, thus improving the applicability of the reinforcement structure. 4. In the adjustable reinforcement structure for modular bridge splice gaps, when processing the filling material, the air gun can be used in conjunction with the structure that agitates the material to tumble and agitate the reinforcement material in the bridge gap, so that the reinforcement material can fit into various positions of the bridge gap, reduce the size of the gap between the reinforcement material and the bridge, and improve the quality of the bridge gap after reinforcement.

[0067] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application. Example 1

[0068] Please see Figures 1-12The adjustable reinforcement structure for modular bridge splice gaps includes a base 10, rollers 20, a box 30, a material casting component 40, an integrated mixing drive mechanism 50, a push handle 60, and an air gun 70. Multiple rollers 20 are movably arranged inside the base 10. The box 30 is installed at the center of the top of the base 10. The integrated mixing drive mechanism 50, extending outwards, is installed inside the box 30 and connected to the multiple rollers 20. The material casting component 40 is installed on one side of the box 30, located to the side of the integrated mixing drive mechanism 50. An air gun 70 is mounted on the top of the base 10 and also installed on the top of the base 10. Equipped with a push handle 60, the integrated mixing drive mechanism 50 includes an intermediate stirring component 80, which is installed inside the housing 30 and extends to the bottom of the housing 30. A belt drive component 90 is connected to one side of the intermediate stirring component 80, which passes through the base 10 and is connected to two rollers 20. An adjustable mixing component 100 is installed on the top of the base 10 and is connected to the other side of the intermediate stirring component 80. A housing 30 and an air gun 70 are provided on one side of the adjustable mixing component 100, and a push handle 60 is provided on the back of the adjustable mixing component 100.

[0069] The working principle described above is as follows: When reinforcing materials are injected into the gaps of a modular bridge to enhance its strength, the mixed materials (concrete and asphalt, etc.) are first added to the interior of the box 30, and then injected into the gaps through the material casting component 40. During the material filling process, the intermediate mixing component 80 can drive the material to stir, ensuring its activity and smoother movement within the material casting component 40 and the gaps. Simultaneously, the intermediate mixing component 80 can drive the belt drive component 90, causing the two rollers 20 to rotate continuously, enabling automatic movement of the device structure. This method is highly efficient, cost-effective, and low-noise when reinforcing gaps. Furthermore, in actual operation, the adjustable mixing component 100 can be used to mix the filling material (this can be controlled), agitating the material inside the gaps to reduce the probability of large air bubbles remaining after solidification, thus increasing the strength of the bridge after curing.

[0070] For details, please refer to the following: Figure 5The material casting assembly 40 includes a pump 401, a pumping pipe 402, and a nozzle 403. The pump 401 is mounted on the top edge of the base 10 by screws. The input end of the pump 401 extends into the interior of the housing 30 through the pumping pipe 402. There are two pumping pipes 402. The output end of the pump 401 is connected to another pumping pipe 402. The nozzle 403 is installed at the bottom of the other pumping pipe 402.

[0071] In the adjustable reinforcement structure for modular bridge splice gaps of the present invention, the material located inside the box 30 can be transferred through the extraction pipe 402 to the inside of the nozzle 403 by the power generated by the extraction pump 401, and then sprayed out from the inside of the nozzle 403 to realize the discharge operation of the solidified material.

[0072] For details, please refer to the following: Figure 5 , Figure 7 and Figure 8 The intermediate stirring assembly 80 includes a drive motor 801, which is installed at the center of the top of the housing 30. The output end of the drive motor 801 is connected to a stirring shaft 802, which is rotatably located at the center inside the housing 30 and extends to the bottom of the housing 30. There are also stirring blades 804, which are installed on the outside of the stirring shaft 802. Several stirring blades 804 are provided. At the bottom of the stirring blades 804, there are pusher blades 805 installed on the outside of the stirring shaft 802. The pusher blades 805 are rotatably connected to the bottom of the housing 30. An intermediate gear 806 is installed on the outside of the bottom of the stirring shaft 802 and is rotatably connected to the top of the base 10.

[0073] In this embodiment, vertical gears 807 are meshed on the left and right sides of the intermediate gear 806. A horizontal shaft 808 is mounted on the side of the vertical gear 807. The horizontal shaft 808 is movably disposed on the top of the base 10. A transmission belt 803 is connected to the outer side of the horizontal shaft 808 via a keyed synchronous pulley. There are two transmission belts 803. The inner side of one transmission belt 803 is connected to a belt drive assembly 90 via a keyed synchronous pulley, and the inner side of the other transmission belt 803 is connected to an adjustable mixing assembly 100 via a keyed synchronous pulley.

[0074] In the above embodiment, when the intermediate gear 806 rotates, the vertical gears 807 meshing with its left and right sides can rotate, allowing the horizontal shaft 808 connected to the side of the vertical gear 807 to rotate. When the horizontal shaft 808 rotates, the transmission belt 803 connected to the synchronous pulley via a key on its outer side can operate, driving the belt drive assembly 90 and the adjustable mixing assembly 100 to operate respectively.

[0075] In the adjustable reinforcement structure for modular bridge splice joints of the present invention, when the material is stirred to ensure its activity and fluidity, the drive motor 801 is started to operate, driving the stirring shaft 802 connected to the output end of the drive motor 801 to rotate, so that the multiple stirring blades 804 installed on the outside of the stirring shaft 802 can rotate, realizing the stirring and mixing operation of the material. When the stirring shaft 802 rotates, the intermediate gear 806 connected to its bottom can rotate, and at the same time, it can also drive the pusher blades 805 to rotate, pushing the material at the bottom of the box 30 and moving the material to one side of the extraction pipe 402.

[0076] For details, please refer to the following: Figure 8 The belt drive assembly 90 includes a movable shaft 901, which is connected to a synchronous pulley via an outer key and is located inside a transmission belt 803. The movable shaft 901 is rotatably connected to the inside of an upper support 902, which is mounted on the top of the base 10. The drive belt 903 is connected to the outer side of the movable shaft 901 via a synchronous pulley key located inside the drive belt 903 and passes through the base 10. A drive shaft 904 is connected to the inner side of the drive belt 903 via a synchronous pulley key. The drive shaft 904 is movably located at the bottom of the base 10, and rollers 20 are installed on the left and right sides of the drive shaft 904.

[0077] In the adjustable reinforcement structure for modular bridge splice gaps of the present invention, when the drive belt 803 operates, the movable shaft 901 connected to it via a synchronous pulley key on its inner side can rotate, thereby enabling the synchronous pulley connected to the outer side of the movable shaft 901 and the drive belt 903 on the outer side of the synchronous pulley to operate. When the drive belt 903 operates, the drive shaft 904 connected to it via a synchronous pulley key on its inner side can rotate, thereby enabling the rollers 20 connected to the left and right sides of the drive shaft 904 to rotate, driving the device to move and travel.

[0078] For details, please refer to the following: Figure 9 , Figure 10 , Figure 11 and Figure 12The adjustable mixing assembly 100 includes a mounting bracket 1001, which is mounted on the top of the base 10 and located on the side of the housing 30. An intermediate shaft 1002 is rotatably connected to the center of the mounting bracket 1001. The intermediate shaft 1002 passes through a partition 1003, which is installed inside the mounting bracket 1001. There are two movable gears 1004, which are meshed together and are movably disposed at the bottom of the partition 1003. A longitudinal shaft 1005 is connected through the interior of the other movable gear 1004. The longitudinal shaft 1005 is movably connected to the top of the base 10. The outer side of the longitudinal shaft 1005 is connected to the inner side of another transmission belt 803 via a keyed synchronous pulley.

[0079] In this embodiment, an upper gear 10021 is mounted on the top of the intermediate shaft 1002. Two upper gears 10021 are provided, and both upper gears 10021 are rotatably connected to the top of the mounting bracket 1001. A straight rod 10022 is mounted on the side of the other upper gear 10021. One side of the straight rod 10022 is recessed inward, forming an inner groove 10023. An assembly shaft 10024 is mounted, extending to the outside of the straight rod 10022. The assembly shaft 10024 matches the inner groove 10023. An assembly gear 10025 is mounted on the side of the assembly shaft 10024. Two assembly gears 10025 are provided, and the two assembly gears 10025 are meshed and connected. Both assembly gears 10025 are rotatably connected to the top of the movable seat 10026.

[0080] In the above embodiment, when the intermediate shaft 1002 rotates, the upper gear 10021 mounted on its top can rotate, allowing another upper gear 10021, which is meshed with the side of the upper gear 10021, to rotate. When the other upper gear 10021 rotates, the straight rod 10022 connected to its side can rotate. When the straight rod 10022 extends into the interior of the assembly shaft 10024, the rotation of the straight rod 10022 can drive the assembly shaft 10024 to rotate, allowing the assembly gear 10025 connected to the bottom of the assembly shaft 10024 to rotate. When the assembly gear 10025 rotates, another assembly gear 10025, which is meshed with the side of the other assembly gear 10025, can rotate, allowing the rotating mixing component 110 connected to the bottom of the other assembly gear 10025 to operate.

[0081] In this embodiment, the movable seat 10026 is slidably connected inside the horizontal groove 10027, which is opened inside the mounting bracket 1001. The movable seat 10026 is connected to the output end of the telescopic cylinder 10028, which is installed inside the horizontal groove 10027. The bottom of another mounting gear 10025 is connected to a rotating mixing component 110.

[0082] In the above embodiments, when it is necessary to operate the rotating mixing component 110, the telescopic cylinder 10028 is activated, allowing the movable seat 10026 connected to its output end to move within the horizontal groove 10027, and allowing the assembly shaft 10024 connected to the side of the movable seat 10026 to move. When the assembly shaft 10024 is connected to the straight rod 10022, it can drive the rotating mixing component 110 to operate; when the assembly shaft 10024 is not connected to the straight rod 10022, it will not drive the rotating mixing component 110 to operate.

[0083] In the adjustable reinforcement structure for modular bridge splice gaps of the present invention, when another drive belt 803 is in operation, the longitudinal shaft 1005 connected to its inner side via a synchronous pulley key can rotate, causing the movable gear 1004 mounted on the outer side of the longitudinal shaft 1005 to rotate. When the movable gear 1004 rotates, another movable gear 1004 meshing with its side can rotate, causing the intermediate shaft 1002 connected to the top of the other movable gear 1004 to rotate.

[0084] In this invention, the design of the inner groove 10023 ensures that the straight rod 10022 can move inside the assembly shaft 10024. When the straight rod 10022 rotates, it can also drive the assembly shaft 10024 to rotate.

[0085] For details, please refer to the following: Figure 10 and Figure 12 The rotating mixing component 110 includes a mixing rod 1101, which is connected to another assembly gear 10025. The mixing rod 1101 passes through the movable seat 10026, and an assembly fixture 1102 is installed at the bottom of the mixing rod 1101. A hydraulic cylinder 1103 is installed inside the assembly fixture 1102, and the output end of the hydraulic cylinder 1103 is connected to a mixing roller 1104, which extends into the interior of the bridge splicing joint.

[0086] In this embodiment, a limiting disc 11011 is installed on the outer side of the mixing rod 1101. The limiting disc 11011 is slidably connected to the top of the triangular support 11012. The triangular support 11012 is installed on the side of the mounting bracket 1001. The mixing rod 1101 is provided through the guide groove 11013. The guide groove 11013 is opened inside the triangular support 11012. An assembly fixture 1102 is provided below the triangular support 11012.

[0087] In the above embodiment, when the movable seat 10026 moves, the mixing rod 1101, which is installed inside it, can move within the guide groove 11013 inside the triangular support 11012. With the help of the limiting disc 11011, the mixing rod 1101 can always be supported, ensuring the stability and firmness of mixing materials.

[0088] In the adjustable reinforcement structure for modular bridge splice gaps of the present invention, when the assembly gear 10025 rotates, the mixing rod 1101 connected to its bottom can rotate, causing the mixing roller 1104 connected to the bottom of the mixing rod 1101 via the hydraulic cylinder 1103 to rotate, thus mixing the filled material and preventing the material from containing a large number of air bubbles. The mixing roller 1104, which performs the mixing, can be raised and lowered by the operation of the hydraulic cylinder 1103, making it convenient to move the mixing roller 1104 into the interior of the material.

An outward-expanding nozzle 122 is installed and fixed on the outer side of the bottom of the conical nozzle 121. A channel is provided between the conical nozzle 121 and the outward-expanding nozzle 122. A fluid divider 123 located at the connection between the conical nozzle 121 and the outward-expanding nozzle 122 is installed inside the channel. An oblique injection port 124 communicating with the channel is opened inside the outward-expanding nozzle 122. A heating layer 125 is provided inside the outward-expanding nozzle 122 and fills the top of the oblique injection port 124.

[0090] In the adjustable reinforcement structure for modular bridge splice joints of this invention, the design of the flow divider 123 can split the high-speed concrete slurry flow into multiple fine streams, forcing the material to undergo local disturbance and recombination within the outward-expanding nozzle 122, and then spraying it obliquely from the oblique spray port 124. This significantly enhances the mixing degree of concrete with compressed air and liquid accelerator, reducing the difference in rebound rate and insufficient local strength caused by uneven mixing. At the same time, the concrete material is sprayed out in a more dispersed and stable conical jet, making it easier for the operator to control the coverage area and thickness, thus improving the ability and effect of reinforcing bridge splice joints.

[0091] Therefore, any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this invention, based on the technical solution and inventive concept of this invention, should be covered within the protection scope of this invention.
