Description

Technical Field

[0001] This utility model relates to the field of engineering construction technology, specifically a protective mechanism for hanging baskets used in the construction of continuous beam cantilever grouting across a high-speed railway. Background Technology

[0002] With the continuous advancement of transportation infrastructure construction, the construction of continuous beam bridges spanning operational highways is increasing. The continuous beam cantilever casting construction technology has become a common method for the construction of bridges spanning highways due to its advantage of being able to carry out the construction of the bridge superstructure without interrupting traffic below. When carrying out continuous beam cantilever casting construction, protective structures are required to protect the area below the construction site.

[0003] Traditional protective structures rely on rigidity to block falling objects, lacking energy absorption mechanisms and unable to buffer instantaneous impact forces. This results in the impact force acting directly on the structure, easily causing it to break, deform, and fail, leading to secondary damage to high-speed vehicles and facilities. Therefore, there is an urgent need to develop a protective mechanism for hanging baskets used in the construction of continuous beam cantilevered grouting on cross-operation high-speed highways to solve these practical problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a protective mechanism for hanging baskets used in the construction of continuous beam cantilevered concrete grouting across high-speed railways. This mechanism solves the problem that traditional protective structures rely on rigidity to block falling objects, lack an energy absorption mechanism, and cannot buffer instantaneous impact forces. As a result, the impact forces act directly on the structure, easily causing it to break, deform, and fail, thus leading to secondary damage to high-speed vehicles and facilities.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a protective mechanism for hanging basket construction of continuous beams across operating highways, including a box girder, an upper truss installed on the top of the box girder through a hanging basket installation assembly, a bottom platform installed on one side of the upper truss through a platform connection assembly, and a protective railing set on the outside of the bottom platform, and a frame installed on the outside of the upper truss through a frame connection assembly.

[0006] It also includes a protective mechanism body, which includes multiple sets of limiting columns set inside the frame. A movable plate is movably installed on the outside of the limiting columns. A connector extending into the frame is fixedly connected to one side of the movable plate. A high-strength nylon net bag for protecting and intercepting falling objects generated during construction is connected to one side of the connector. Collapse members are installed at equal intervals at the bottom inside the frame. The top of the collapse member is fixedly connected to the bottom of the movable plate.

[0007] Preferably, the hanging basket installation assembly includes a traveling guide rail disposed on the top of the box girder, and an anchor beam is movably disposed on the top of the traveling guide rail, with the top of the anchor beam fixedly connected to the bottom of the upper truss.

[0008] Preferably, the platform connection assembly includes a first crossbeam disposed on one side of the upper truss, a second crossbeam fixedly connected to the other side of the upper truss, a first hanger rod being threadedly installed inside the first crossbeam, a second hanger rod being threadedly installed inside the second crossbeam, a first bottom beam being disposed at the bottom of the first hanger rod, a second bottom beam being disposed at the bottom of the second hanger rod, and the tops of the first bottom beam and the second bottom beam being fixedly connected to the bottom of the bottom platform, respectively.

[0009] Preferably, the frame connection assembly includes multiple sets of connecting arms disposed on the outside of the upper truss, with a third hanger threadedly installed inside the connecting arm, and the bottom end of the third hanger threadedly connected to the frame.

[0010] Preferably, it also includes an early warning component, which includes two sets of magnetostrictive force sensors disposed on both sides of the top of the frame. The measuring end of the magnetostrictive force sensor penetrates through the interior of the movable plate. A position magnet is fixedly connected to the top of the movable plate. The position magnet is located outside the measuring end of the magnetostrictive force sensor and is magnetically connected to it. Two sets of mounting seats are also installed on the top of the frame, and an audible and visual alarm is fixedly connected to the top of the mounting seat.

[0011] Preferably, the collapsible component is made of aluminum alloy and has a Z-shaped shape.

[0012] This utility model provides a protective mechanism for hanging baskets used in the cantilever construction of continuous beams across operational highways. Compared with existing technologies, it has the following advantages.

[0013] 1. The frame is installed below the base platform via the connecting arm and the third boom. High-strength nylon netting is used to intercept falling objects from the construction site, preventing them from falling onto the highway below and ensuring highway traffic safety. Large falling objects will land in the high-strength nylon netting, which will transmit force to the moving plate through the connector, causing it to move along the limit post and compress the aluminum alloy crumple zone. The crumple zone will collapse and deform under the force to absorb the impact, achieving buffering and shock absorption, and preventing damage to the protective structure and objects below due to large impact forces.

[0014] 2. When construction objects fall and impact a high-strength nylon net bag, the net bag, via connectors, causes a movable plate to move along a limiting post. This displacement of the top magnet, combined with an external controller, sends a command to an audible and visual alarm. The alarm then triggers, alerting construction personnel to take timely action. This provides effective early warning of falling objects and addresses the problem of heavy falling objects being difficult to detect in time, thus preventing potential hazards during construction.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] First implementation method:

[0023] refer to Figure 1-5 A protective mechanism for hanging basket construction of continuous beam across a high-speed railway includes a box girder 1, an upper truss 2 installed on the top of the box girder 1 via a hanging basket installation assembly, a bottom platform 3 installed on one side of the upper truss 2 via a platform connection assembly, and a guardrail 301 set on the outside of the bottom platform 3. A frame 402 is installed on the outside of the upper truss 2 via a frame connection assembly.

[0024] It also includes a protective mechanism body 5, which includes multiple sets of limiting posts 501 set inside the frame 402. A movable plate 502 is movably installed on the outside of the limiting posts 501. A connector 503 extending into the frame 402 is fixedly connected to one side of the movable plate 502. A high-strength nylon net bag 504 for protecting and intercepting falling objects generated during construction is connected to one side of the connector 503. Collapsible members 505 are installed at equal intervals at the bottom inside the frame 402. The top of the collapsible member 505 is fixedly connected to the bottom of the movable plate 502.

[0025] The hanging basket installation assembly includes a traveling guide rail 101 set on the top of the box girder 1, and an anchor beam 102 movably set on the top of the traveling guide rail 101. The top of the anchor beam 102 is fixedly connected to the bottom of the upper truss 2.

[0026] The platform connection assembly includes a first crossbeam 201 disposed on one side of the upper truss 2, and a second crossbeam 202 fixedly connected to the other side of the upper truss 2. A first hanger 203 is threadedly installed inside the first crossbeam 201, and a second hanger 204 is threadedly installed inside the second crossbeam 202. A first bottom beam 205 is disposed at the bottom of the first hanger 203, and a second bottom beam 206 is disposed at the bottom of the second hanger 204. The tops of the first bottom beam 205 and the second bottom beam 206 are respectively fixedly connected to the bottom of the bottom platform 3.

[0027] The frame connection assembly includes multiple sets of connecting arms 4 located on the outside of the upper truss 2. A third hanger 401 is threadedly installed inside the connecting arm 4. The bottom end of the third hanger 401 is threadedly connected to the frame 402. The collapsible member 505 is made of aluminum alloy and has a Z-shaped shape.

[0028] The box girder 1 bears all kinds of loads in the entire device and construction process, providing a stable foundation for the subsequent structure. The traveling guide rail 101 is set on the top of the box girder 1, so that the anchor beam 102 can move on its top, making it easy for the upper truss 2 to flexibly adjust its position to adapt to construction needs.

[0029] The upper truss 2 is securely installed on the box girder 1 via the traveling guide rail 101 and the anchor beam 102, serving as a connection and support. The first crossbeam 201 on one side and the second crossbeam 202 passing through on the other side are respectively connected by threads to the first hanger 203 and the second hanger 204. The bottom of the first hanger 203 and the second hanger 204 are respectively provided with the first bottom beam 205 and the second bottom beam 206, thereby connecting the bottom platform 3 and transferring the supporting force of the upper truss 2 to the bottom platform 3, so that the bottom platform 3 remains stable and provides a working area for construction personnel. The guardrail 301 can provide safety protection for the bottom platform 3, thereby reducing the falling of debris.

[0030] After the frame 402 is installed below the bottom platform 3 by connecting arm 4 and third suspender 401, the high-strength nylon net bag 504 can intercept falling objects generated during construction, thereby preventing falling objects from falling onto the operating highway section below and ensuring the safety and smooth flow of highway traffic.

[0031] When a large object falls into the high-strength nylon net bag 504, the high-strength nylon net bag 504 transmits the force to the moving plate 502 through the connector 503, thereby driving the moving plate 502 to move along the limiting post 501, and thus compressing the collapsible member 505.

[0032] Because the collapse component 505 is made of aluminum alloy, it will collapse when subjected to force. By collapsing and deforming, it absorbs the impact force of falling objects, thus achieving the function of buffering and shock absorption. This solves the real and reasonable problem that excessive impact force from falling objects may cause damage to the protective structure and serious damage to objects below.

[0033] Second implementation method:

[0034] If a heavy object remains inside the protective net for an extended period of time, and construction workers are unable to detect it in time, they may be unable to take timely protective measures, leading to safety hazards in subsequent construction.

[0035] refer to Figure 4-5 In the second embodiment of this utility model, an early warning component 6 is also included. The early warning component 6 includes two sets of magnetostrictive force sensors 601 disposed on both sides of the top of the frame 402. The measuring end of the magnetostrictive force sensor 601 penetrates the interior of the moving plate 502. A position magnet 602 is fixedly connected to the top of the moving plate 502. The position magnet 602 is located outside the measuring end of the magnetostrictive force sensor 601 and is magnetically connected to it. Two sets of mounting seats 603 are also installed on the top of the frame 402. An audible and visual alarm 604 is fixedly connected to the top of the mounting seat 603.

[0036] When falling objects generated during construction impact the high-strength nylon net bag 504, the high-strength nylon net bag 504 transmits the force to the moving plate 502 through the connector 503, thereby causing the moving plate 502 to move along the limiting post 501. At this time, the position magnet 602 fixed at the top of the moving plate 502 will be displaced synchronously.

[0037] Since the position magnet 602 is connected to the measuring end of the magnetostrictive force sensor 601 by magnetic force, the change in position of the position magnet 602 will cause the magnetic field inside the magnetostrictive force sensor 601 to change, which in turn causes it to generate a corresponding change in electrical signal. This changed electrical signal is transmitted to an external controller through a wire, and the external controller analyzes and processes the electrical signal.

[0038] When the electrical signal characteristics indicate that a heavy object has been received in the high-strength nylon net bag 504, the external controller will send a control command to the audible and visual alarm 604. After receiving the command, the audible and visual alarm 604 will immediately trigger and issue a strong audible and visual alarm.

[0039] This sound and light alarm can promptly attract the attention of construction workers, reminding them that a heavy object has fallen into the high-strength nylon net 504 and needs to be dealt with in time. Through this working mechanism, an effective early warning function for falling objects is achieved, which effectively solves the problem that if a heavy object remains inside the high-strength nylon net 504 for a long time, construction workers may not be able to detect it in time, and thus may not be able to take protective measures in time, leading to safety hazards in subsequent construction.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
