Description

Technical Field

[0001] This utility model relates to the field of construction platform technology, specifically to a reverse-hanging support rod. Background Technology

[0002] In bridge maintenance and reinforcement projects, especially for the reinforcement of old bridges, the construction of a construction platform is a crucial step. The construction platform not only provides working space for construction workers but also ensures safety and efficiency during the construction process. However, traditional construction platform hoist designs have many shortcomings, particularly in the specific application scenario of old bridge reinforcement.

[0003] First, traditional booms often lack the ability to retract freely. This means that when setting up and dismantling the construction platform, workers need to spend more time and effort adjusting the boom length to adapt to different construction needs. This not only increases the difficulty of construction but also reduces work efficiency.

[0004] Secondly, the installation and dismantling process of traditional booms is relatively cumbersome. Due to the lack of flexibility in boom design, construction workers often need to rely on complex tools and equipment to complete the installation and dismantling work. This not only increases construction costs but may also pose a threat to the safety of construction workers. Utility Model Content

[0005] This utility model proposes a reverse hanging bracket rod to solve the technical defects pointed out in the background art.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0007] A reverse-hanging support rod includes a rod body, which includes an upper rod, a lower rod, and an adjustable sleeve connected between the upper rod and the lower rod. The opposite ends of the upper rod and the lower rod form U-shaped suspension positions, and safety locks are respectively provided on the two U-shaped suspension positions. By adjusting the adjustable sleeve, the upper rod and the lower rod can move towards or away from each other.

[0008] Furthermore, the ends of the upper and lower suspension rods away from their U-shaped suspension positions form threaded sections, and the adjusting sleeve is correspondingly provided with upper and lower threaded holes that allow the threaded sections to extend into and engage with the threads.

[0009] Furthermore, the threaded sections of the upper and lower suspension rods are arranged in opposite directions, and the threaded directions of the upper and lower threaded holes are also arranged in opposite directions.

[0010] Furthermore, the safety device includes a slot located inside the U-shaped lifting position and a rotating clamp located on the other side of the U-shaped lifting position via a rotating shaft. The rotating clamp engages with the slot after rotation.

[0011] Furthermore, the U-shaped lifting position of the upper suspension rod cooperates with the nut pre-embedded in the bottom of the old bridge, the U-shaped lifting position of the lower suspension rod cooperates with the steel pipe member, and the steel pipe member is fixedly connected to the construction platform.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention adjusts the overall length of the suspension rod by adjusting an adjusting sleeve located between the upper and lower suspension rods. The upper and lower threaded holes of the sleeve engage with the opposite threaded sections of the upper and lower suspension rods, allowing the upper and lower suspension rods to move in opposite directions. A safety catch on the U-shaped suspension position enhances the stability and safety of the suspension rod at the connection point through the engagement of a rotating clamp with a slot. This reverse-suspension support, through the adjusting sleeve design, allows for flexible adjustment of the suspension rod length to adapt to different construction needs. Simultaneously, the safety catch enhances the stability and safety of the suspension rod at the connection point, reducing construction risks. Attached Figure Description

[0020] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0022] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0024] like Figure 1-5 As shown, a ground-mounted suspended combined construction platform is installed on the road surface section and the river-crossing section of an old bridge 1. It includes a ground-mounted support 2 erected on the road surface section below the old bridge 1, with one section of the construction platform 5 fixedly mounted on the ground-mounted support 2. It also includes several suspension devices 4 arranged along the length of the old bridge 1 at the bottom of the river-crossing section. The other section of the construction platform 5 is suspended and fixed below the old bridge 1 by the suspension devices 4. The suspension device 4 includes expansion bolts 41 fixed to the bottom of the old bridge 1, and hexagonal nuts 42 threadedly connected to the lower section of the expansion bolts 41. The lower end of the hexagonal nuts 42 is fixedly connected to a nut 43. The nut 43 is suspended to the upper end of a rod 45, and the lower end of the rod 45 is suspended to the construction platform 5.

[0025] The expansion bolt 41 is fixed to the bottom of the old bridge 1 by the frictional gripping force it generates. When the expansion bolt is screwed into the pre-drilled hole, the expansion tube inside it will open due to the taper of the bolt, forming a tight frictional self-locking with the hole wall at the bottom of the old bridge, thereby ensuring that the construction platform can be stably suspended under the old bridge by the suspension device.

[0026] The hexagonal nut 42 is threaded to the lower section of the expansion bolt 41. Tightening the hexagonal nut further ensures the fixing effect of the expansion bolt.

[0027] The lower end of the hexagonal nut 42 is fixedly connected to the lifting nut 43. The lifting nut 43 is a device used for lifting and securing objects, which has high strength and corrosion resistance and can ensure a reliable connection with the lifting rod 45.

[0028] The upper end of the boom 45 is connected to the nut 43, and the lower end is connected to the construction platform 5. As a key component connecting the nut and the construction platform, the boom operates on the principle of using the weight of the object and the torque generated by gravity to achieve the purpose of suspending the object. When the construction platform 5 needs to be suspended under the old bridge 1, the boom 45 bears the weight of the construction platform and transfers the weight to the expansion bolts 41 through the nut 43 and hexagonal nuts 42, ultimately borne by the bottom of the old bridge 1. In the entire system, the ground support 2 is responsible for supporting part of the weight of the construction platform 5 on the road surface section below the old bridge 1, while the suspension device 4 is responsible for suspending the other section of the construction platform 5 at the bottom of the river-crossing section of the old bridge 1.

[0029] The boom 45 includes a boom body, which includes an upper boom 451, a lower boom 452, and an adjusting sleeve 454 adjustable between the upper boom 451 and the lower boom 452. The opposite ends of the upper boom 451 and the lower boom 452 form U-shaped lifting positions 455, each equipped with a safety catch 46. Adjusting the adjusting sleeve 454 allows the upper boom 451 and the lower boom 452 to move towards or away from each other. The ends of the upper boom 451 and the lower boom 452 away from their U-shaped lifting positions 455 form threaded sections 453. The adjusting sleeve 454 contains corresponding upper and lower threaded holes that allow the threaded sections to extend into and engage with the threads. The threaded sections 453 of the upper boom 451 and the lower boom 452 have opposite thread directions, and the upper and lower threaded holes also have correspondingly opposite thread directions.

[0030] When the length or height of the suspension rod 45 needs to be adjusted, this can be achieved by rotating the adjusting sleeve 454. Since the threaded sections 453 of the upper suspension rod 451 and the lower suspension rod 452 are opposite in direction to the threaded holes within the adjusting sleeve 454, when the adjusting sleeve 454 is rotated, the upper suspension rod 451 and the lower suspension rod 452 will move in opposite directions or away from each other. If the adjusting sleeve 454 rotates clockwise, for example, the upper suspension rod 451 may move upwards due to the threaded engagement (depending on the specific thread design and rotation direction), while the lower suspension rod 452 will move downwards, and vice versa. This opposite or opposite movement allows the overall length of the suspension rod 45 to be adjusted as needed to meet different suspension or connection requirements.

[0031] Specifically, as shown in the figure, the safety device 46 includes a slot 461 located inside the U-shaped lifting position 455 and a rotating locking member 463 rotatably mounted on the other side of the U-shaped lifting position 455 via a rotating shaft 462. The rotating locking member 463 engages with the slot 461 after rotation. This engagement provides additional connection strength and stability, ensuring that the lifting rod 45 will not accidentally detach or loosen under load.

[0032] Specifically, as shown in the figure, the U-shaped lifting position 455 of the upper lifting rod 451 cooperates with the lifting nut 43 pre-embedded in the bottom of the old bridge, the U-shaped lifting position 455 of the lower lifting rod 452 cooperates with the steel pipe member 6, and the steel pipe member 6 is fixedly connected to the construction platform 5.

[0033] Specifically, as shown in the figure, a washer is provided between the hexagonal nut 42 and the expansion bolt 41.

[0034] Specifically, as shown in the figure, a construction access road 3 is erected inside the ground support 2.

[0035] Specifically, as shown in the figure, the ground support 2 is a detachable steel structure support, which is set on the road surface section below the old bridge 1 to support and fix a part of the construction platform 5.

[0036] This invention utilizes a ground-supported frame to hold the construction platform partially above the existing bridge's road surface, while a suspension device suspends the other end of the platform above the river-crossing section of the old bridge. The suspension device is fixed to the bottom of the old bridge with expansion bolts and connected to a suspension rod via hexagonal nuts, washers, and nutlets. The suspension rod forms a U-shaped suspension position at both ends and is equipped with safety locks to ensure stable suspension of the construction platform. This construction platform has a stable structure, is easy to disassemble and reassemble, and can adapt to the renovation needs of different old bridges. The provision of a construction access road improves construction efficiency, while the safety locks further ensure the safety of construction personnel.

[0037] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.

[0038] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
