Description

Technical Field

[0001] This utility model relates to the field of building construction technology, specifically to a rhomboid truss hanging basket structure for bridges. Background Technology

[0002] The rhomboid truss hanging basket structure is a common bridge construction technique, mainly used in the construction of suspension bridges or cable-stayed bridges. This structure effectively supports the construction weight of the bridge while allowing construction workers to work safely beneath it. Its main components include tracks on the bridge deck, rhomboid hangers, transverse trusses, and hanging baskets beneath the bridge. Chinese Patent Publication No. CN215329405U discloses a main truss for a bridge hanging basket, comprising an upper horizontal bar, a front diagonal bar, a lower horizontal bar, a rear diagonal bar, a central upright, a first node seat, a second node seat, a third node seat, and a fourth node seat, all connected end-to-end to form a rhomboid structure. The second and third node seats are connected to the central upright.

[0003] When installing a diamond-shaped hanging basket structure, hand-operated hoists are required to be placed on both sides of the diamond-shaped frame to tighten and fix it, thereby enhancing lateral stability. However, since the hand-operated hoists on both sides need to maintain a balanced tension, otherwise it will affect the lateral stability. Furthermore, if one hand-operated hoist malfunctions, the other hand-operated hoist will also lose its fixing effect, posing a safety hazard. Utility Model Content

[0004] To address the aforementioned problems, this utility model provides a diamond-shaped truss hanging basket structure for bridges, which solves the problem that using hand-operated hoists to fix the two sides of the diamond-shaped hanger makes it difficult to maintain lateral stability and poses potential hazards.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rhomboid truss hanging basket structure for bridges, including a support rail and a rhomboid support frame, and also including a positioning component. The positioning component is disposed on one side of the support rail and the rhomboid support frame, and is attached to the surface of the rhomboid support frame for positioning. The positioning component includes a base, an adjustment mechanism, a locking mechanism and a limiting mechanism.

[0006] The support rail is fixed to the bridge deck, and its top is provided with a diamond-shaped support frame. The base is fixed to the bridge deck and located on one side of the support rail.

[0007] The base includes a support plate and a sliding groove. The top of the support plate has a sliding groove, and an adjustment mechanism is slidably installed inside the sliding groove. A locking mechanism is slidably installed on the top of the adjustment mechanism.

[0008] The adjustment mechanism includes a slider, a slide rod, and a steel cable. The slider is slidably installed inside the slide groove, the slide rod is fixedly installed on the top of the slider, and the steel cable is provided on the top of the slider.

[0009] The locking mechanism includes a slide block, a locking plate, and a pulley. The slide block is slidably mounted on the surface of the slide rod, the locking plate is fixedly mounted on the top of the slide block, the pulley is rotatably mounted on the top of the slide block, and the steel cable is sleeved on the top of the pulley.

[0010] The support plate is provided with a limiting mechanism on one side, and the limiting mechanism is connected to one side of the adjusting mechanism.

[0011] The adjustment mechanism also includes a winding roller, a rotating wheel, and a stop plate. A fixed plate is installed on the surface of the slider. The winding roller is rotatably installed on one side of the fixed plate. One end of the steel cable is fixed to the top of the slider, and the other end is fixed to the surface of the winding roller.

[0012] A rotating shaft is fixedly installed inside the winding roller. The rotating shaft is rotatably connected to the winding roller, and one end of the rotating shaft passes through the fixed plate. A rotating wheel is fixedly sleeved on its surface, and a handle is fixedly installed on one end of the rotating shaft.

[0013] A stop plate is rotatably mounted on the other side of the fixed plate, and a torsion spring is provided at the rotation point of the stop plate. The stop plate and the rotating wheel are meshed together.

[0014] The limiting mechanism includes a threaded rod, a connecting plate, a limiting plate, and a guide rod. The threaded rod is threadedly installed on one side of the support plate. The connecting plate is slidably fitted onto the surface of the threaded rod. The limiting plate is fixedly installed on the top of the connecting plate, and the guide rod is fixedly installed on the bottom of the threaded rod.

[0015] The slider has a threaded hole on one side, and the threaded hole is corresponding to one end of the threaded rod. The limit plate has an L-shaped cross section, and the guide rod is slidably inserted into one side of the support plate.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention adjusts the position of the locking plate by pushing the slider to slide inside the groove and simultaneously pushing the slide block to slide on the surface of the slide rod, thereby locking it onto the top of the diamond-shaped support frame and fitting it against the top two sides of the diamond-shaped support frame. The steel cable is then pulled taut to slide along the top of the pulley, pressing down on the slide block and pulling the locking plate to tightly fasten it to the top of the diamond-shaped support frame. This enhances the lateral stability of the diamond-shaped support frame and avoids the inconvenience of needing to install hand-operated hoists on both sides and maintain their tension balance, as well as the safety hazard caused by the failure of one hand-operated hoist leading to the ineffective fixing effect of the other hand-operated hoist. The limiting mechanism is turned to limit the movement of the slider and simultaneously limit and fix the downward traction of the steel cable. Attached Figure Description

However, those skilled in the art should understand that the detailed description given here with reference to the accompanying drawings is for better explanation. The structure of the present invention may exceed the limited embodiments described herein. Some equivalent alternatives or common means will not be described in detail here, but they still fall within the protection scope of this application.

[0025] Figures 1-5 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-5 The present invention will be further described below.

[0026] A rhomboid truss hanging basket structure for bridges includes a support rail 1 and a rhomboid support frame 2, and a positioning component. The positioning component is disposed on one side of the support rail 1 and the rhomboid support frame 2, and is positioned against the surface of the rhomboid support frame 2. The positioning component includes a base 3, an adjusting mechanism 4, a locking mechanism 5, and a limiting mechanism 6. The support rail 1 is fixed to the bridge deck, and the rhomboid support frame 2 is provided on its top. The base 3 is fixed to the bridge deck and located on one side of the support rail 1. The base 3 includes a support plate 301. The top of the support plate 301 is provided with a slide groove 302. An adjustment mechanism 4 is slidably installed inside the slide groove 302, and a locking mechanism 5 is slidably installed on the top of the adjustment mechanism 4. The adjustment mechanism 4 includes a slider 401, a slide rod 402, and a steel cable 404. The slider 401 is slidably installed inside the slide groove 302, and the slide rod 402 is fixedly installed on the top of the slider 401. The steel cable 404 is located on the top of the slider 401. The locking mechanism 5 includes a slide base 501, a locking plate 502, and a sliding... Wheel 503 and slide block 501 are slidably mounted on the surface of slide rod 402. A clamping plate 502 is fixedly mounted on the top of slide block 501, and the top of clamping plate 502 is U-shaped and fits against the top and sides of the rhomboid support frame 2. Pulley 503 is rotatably mounted on the top of slide block 501, and steel cable 404 is sleeved onto the top of pulley 503. A limiting mechanism 6 is provided on one side of support plate 301, and the limiting mechanism 6 is connected to one side of adjusting mechanism 4. Specifically, the rhomboid support is positioned by a positioning component. The frame 2 is stabilized to enhance its lateral stability. The horizontal position is adjusted by controlling the adjustment mechanism 4 to slide on the top of the base 3. At the same time, the height position is adjusted by controlling the locking mechanism 5 to slide on the top of the adjustment mechanism 4. Thus, the locking mechanism 5 is locked to the top of the rhomboid support frame 2. The two fit together to enhance the stability of the connection. The adjustment mechanism 4 is limited and fixed by the limiting mechanism 6, so that the position of the adjustment mechanism 4 is determined and the locking mechanism 5 is restricted to press tightly against the top of the rhomboid support frame 2.

[0027] The positioning mechanism 4 also includes a winding roller 403, a rotating wheel 405, and a stop plate 406. A fixed plate is installed on the surface of the slider 401. The winding roller 403 is rotatably mounted on one side of the fixed plate. One end of the steel cable 404 is fixed to the top of the slider 401, and the other end is fixed to the surface of the winding roller 403. Specifically, the rotation of the winding roller 403 drives the steel cable 404 to wind onto its surface, and the steel cable 404 is pulled past the top of the pulley 503 to apply downward pressure to the positioning mechanism 5.

[0028] A rotating shaft is fixedly installed inside the winding roller 403. The rotating shaft is rotatably connected to the winding roller 403, and one end of the rotating shaft passes through the fixed plate. A rotating wheel 405 is fixedly installed on its surface, and a handle is fixedly installed on one end of the rotating shaft. Specifically, the winding roller 403 is rotated by rotating the handle, which in turn causes the rotating wheel 405 to rotate.

[0029] A stop plate 406 is rotatably mounted on the other side of the fixed plate, and a torsion spring is provided at the rotation point of the stop plate 406. The stop plate 406 is meshed with the rotating wheel 405. Specifically, the rotating wheel 405 pushes the stop plate 406 to rotate, and the torsion spring pulls the stop plate 406 back to its original position.

[0030] The limiting mechanism 6 includes a threaded rod 601, a connecting plate 602, a limiting plate 603, and a guide rod 604. The threaded rod 601 is threadedly installed on one side of the support plate 301. The connecting plate 602 is slidably mounted on the surface of the threaded rod 601. The limiting plate 603 is fixedly installed on the top of the connecting plate 602, and the guide rod 604 is fixedly installed on the bottom of the threaded rod 601. Specifically, by twisting the threaded rod 601, it extends into the interior of the support plate 301. The threaded rod 601 drives the connecting plate 602 to move horizontally, so that the limiting plate 603 approaches the rotating part of the adjusting mechanism 4.

[0031] A threaded hole is provided on one side of the slider 401, and the threaded hole is correspondingly set to one end of the threaded rod 601. The cross-section of the limiting plate 603 is L-shaped, and the limiting plate 603 is correspondingly set to the stop plate 406. The guide rod 604 is slidably inserted into one side of the support plate 301. Specifically, by turning the threaded rod 601, it is gradually extended into the support plate 301 and contacts the slider 401. The threaded rod 601 rotates into its threaded hole, completing the connection and fixing of the threaded rod 601 and the slider 401, thereby limiting and fixing the movement of the slider 401. By pushing the limiting plate 603 to contact the fixing plate and to fit against one side of the limiting plate 603, the rotation of the limiting plate 603 is unidirectionally limited, restricting the rotation of the winding roller 403. The guide rod 604 enables the connecting plate 602 to move horizontally stably during the rotation of the threaded rod 601.

[0032] In summary: When using this utility model, workers are performing construction work on the bridge. When installing the rhomboid truss hanging basket structure, it is necessary to provide lateral stability protection for the rhomboid support frame 2. The support plate 301 is installed on the bridge deck, located on one side of the rhomboid support frame 2. The locking plate 502 is moved, causing the slider 401 to slide inside the sliding groove 302. The sliding seat 501 slides on the surface of the sliding rod 402 until the locking plate 502 is engaged with the top of the rhomboid support frame 2. The U-shaped top of the locking plate 502 fits against both sides of the rhomboid support frame 2. After determining the position of the locking plate 502, the threaded rod 601 is turned, causing the threaded rod 601 to extend into the interior of the support plate 301 until one end of the threaded rod 601 is threaded into the threaded hole of the slider 401, so that the threaded rod 601 contacts the slider 401, completing the limiting and fixing of the slider 401. At the same time, the threaded rod 601 carries... The moving connecting plate 602 moves, and the guide rod 604 keeps the connecting plate 602 moving stably. The connecting plate 602 pushes the limiting plate 603 to contact the fixed plate. The limiting plate 603 fits against one side of the stop plate 406, restricting the stop plate 406 to only rotate in one direction. The steel cable 404 is wrapped around the top of the pulley 503. The handle is rotated, causing the winding roller 403 to rotate and wrap the steel cable 404 around its surface. The steel cable 404 tightens and applies downward pressure to the locking mechanism 5, so that the locking plate 502 is tightly fastened to the top of the diamond support frame 2 and restricts the sliding of the slide block 501. During the rotation of the winding roller 403, the rotating wheel 405 is driven to continuously push the stop plate 406. After the handle is released, due to the limitation of the limiting plate 603 on the stop plate 406, the stop plate 406 cannot be pushed in the opposite direction, thereby restricting the reverse rotation of the winding roller 403.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from its technical solution shall still fall within the protection scope of this utility model.
