Description

Technical Field

[0001] This utility model relates to the field of suspension bracket technology, and in particular to a detachable bridge maintenance and reinforcement suspension bracket. Background Technology

[0002] As a crucial component of transportation infrastructure, the structural safety and durability of bridges directly impact the smooth flow of traffic and the safety of public life and property. With increasing service life, bridges are prone to defects such as cracks, steel corrosion, and component deformation under the combined effects of vehicle loads, natural environmental factors, and material aging. Therefore, regular inspection, maintenance, and reinforcement of bridges are core measures to ensure their safe use. Currently, when inspecting and reinforcing the sides of bridges, suspended supports, commonly known as cages, are generally used, their main function being to provide a working platform for personnel.

[0003] The existing suspension brackets used for bridge maintenance and reinforcement are prone to swaying and tilting due to poor overall structural balance. This imbalance not only affects construction efficiency and quality, but also poses a significant threat to the personal safety of workers due to potential risks such as load imbalance. Utility Model Content

[0004] This utility model relates to a detachable suspension bracket for bridge maintenance and reinforcement, which solves the problem that existing suspension brackets for bridge maintenance and reinforcement are prone to large-scale swaying and tilting under wind load due to insufficient structural balance, which not only affects construction efficiency but also poses a risk of load imbalance and seriously threatens operational safety.

[0005] In a first aspect, this utility model provides a detachable bridge maintenance and reinforcement suspension bracket, specifically comprising: a suspension bracket, the suspension bracket including a hanger, a support cage fixedly connected to the rear end of the hanger, and rollers installed on the front side of the support cage and the inner side of the hanger; a connecting plate fixedly connected to the lower front side of the hanger, and a support rod fixedly connected to the front end face of the connecting plate in a uniform manner; five counterweights movably inserted into the front side of the connecting plate through the support rods in a uniform manner, and five sets of quick-fixing components are provided between the top of the five counterweights and the top of the connecting plate.

[0006] Furthermore, a reinforcing rod is fixedly connected symmetrically between the top of the hanging bracket and the upper front part of the supporting hanging cage.

[0007] Furthermore, the front end face of the counterweight is provided with a through hole for insertion with a support rod; a handle is provided on the top of the counterweight.

[0008] Furthermore, the quick-fixing assembly includes a support block and a snap-fit ​​frame. The support block is fixedly connected to the rear side of the top surface of the counterweight block, and the snap-fit ​​frame is fixedly connected to the top surface of the connecting plate. The front surface of the support block has two rectangular openings that are symmetrically arranged on the left and right sides. Each rectangular opening is fixedly connected to a guide rod. Each rectangular opening is slidably connected to an elastic buckle through the guide rod, and a stainless steel spring is sleeved on the outside of the guide rod.

[0009] Furthermore, when the quick-fixing component is in the limited position, the elastic buckle engages with the inner side of the snap-fit ​​frame.

[0010] This utility model provides a detachable bridge maintenance and reinforcement suspension bracket, which has the following beneficial effects: I. This utility model, through the setting of connecting plates, support rods, and counterweights, allows for the installation of a corresponding number of counterweights on the front side of the connecting plates before operation, based on the weight of the on-site workers. When workers enter the support cage for operation, the counterweights help maintain a good balance between the support cage and the hanging frame, effectively resisting the influence of external wind disturbances and other factors, significantly reducing the amplitude of swaying and tilting of the suspension bracket. In a relatively balanced working environment, it effectively improves construction efficiency and quality, avoids major threats to the personal safety of workers due to load imbalance, and provides a safe and reliable guarantee for bridge maintenance and reinforcement operations.

[0011] Second, this utility model achieves efficient operation of counterweight installation and removal by setting up a quick-fixing component. The installation and removal of counterweight can be easily completed without the aid of tools, thereby improving the convenience of use of the suspension bracket. More importantly, when the counterweight is installed, after the counterweight is pushed backward to the limit position, the two adjacent elastic buckles automatically engage with the inner side of the corresponding snap-fit ​​frame, thereby further improving the smoothness of the counterweight installation operation.

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Example 1: Please refer to Figures 1 to 4 : This utility model proposes a detachable bridge maintenance and reinforcement suspension bracket, comprising: a suspension bracket 1, the suspension bracket 1 including a hanger 101, a support cage 102 fixedly connected to the rear end of the hanger 101, and rollers 103 installed on the front side of the support cage 102 and the inner side of the hanger 101; a connecting plate 2 fixedly connected to the lower front side of the hanger 101, and a support rod 201 uniformly fixedly connected to the front end face of the connecting plate 2, the front side of the connecting plate 2 being movably inserted through the support rod 201. Five counterweights 3 are connected, and five sets of quick-fixing components 4 are set between the top of the five counterweights 3 and the top of the connecting plate 2. Through the setting of the connecting plate 2, the support rod 201 and the counterweights 3, the counterweights 3 can maintain a good balance between the support cage 102 and the hanging frame 101, effectively resisting the influence of external wind disturbances and other factors, significantly reducing the amplitude of swaying and tilting of the suspension bracket 1, and avoiding a major threat to the personal safety of the workers due to load imbalance.

[0017] A reinforcing rod 104 is fixedly connected symmetrically between the top of the hanging bracket 101 and the upper front side of the supporting hanging cage 102, which improves the connection strength between the hanging bracket 101 and the supporting hanging cage 102, making the hanging bracket 1 safer and more reliable in use; the weight of the supporting hanging cage 102 is 15KG to 20KG.

[0018] The counterweight 3 has a insertion hole 301 on its front end face, which is used to insert into the support rod 201 so that the counterweight 3 can be effectively positioned during installation. The counterweight 3 has a handle 302 on its top for easy handling. Each counterweight 3 weighs 20KG to 30KG.

[0019] Example 2, based on Example 1, such as Figure 1 and Figure 4 As shown, the quick-fixing assembly 4 includes a support block 401 and a snap-fit ​​frame 402. The support block 401 is fixedly connected to the rear side of the top surface of the counterweight block 3, and the snap-fit ​​frame 402 is fixedly connected to the top surface of the connecting plate 2. The front surface of the support block 401 has two rectangular openings 404 that are symmetrically arranged on the left and right sides. Each rectangular opening 404 has a guide rod 405 fixedly connected inside, and each rectangular opening 404 has an elastic buckle 403 slidably connected inside through the guide rod 405. A stainless steel spring 406 is sleeved on the outside of the guide rod 405. When quick-fixing... When component 4 is in the limit position, the elastic buckle 403 engages with the inner side of the locking frame 402. By quickly fixing component 4, the installation and removal of counterweight 3 are made more efficient. The installation and removal of counterweight 3 can be easily completed without the aid of tools, thereby improving the convenience of using the suspension bracket 1. Furthermore, when installing counterweight 3, after the counterweight 3 is pushed backward to the limit position, two adjacent elastic buckles 403 automatically engage with the inner side of the corresponding locking frame 402, further improving the smoothness of the counterweight 3 installation operation.

[0020] The working principle of this embodiment is as follows: When performing maintenance and reinforcement work on the side of the bridge, firstly, all the counterweight blocks 3 on the front side of the connecting plate 2 are removed. During disassembly, first pinch the two adjacent elastic buckles 403 in opposite directions so that the two adjacent elastic buckles 403 lose their engagement with the inner side of the corresponding snap-fit ​​frame 402. Then, slide the counterweight blocks 3 forward to remove them. The purpose of removing all the counterweight blocks 3 is to reduce the overall weight of the suspension bracket 1, thereby making it easier to hang the suspension bracket 1 on the bridge crash barrier. Then, hang the suspension bracket 1 on the bridge crash barrier. At this time, the roller 103 rolls outside the bridge crash barrier. Then, install the corresponding number of counterweight blocks 3 on the front side of the connecting plate 2 according to the weight of the worker (for example, if the maintenance worker weighs about 75 catties, four counterweight blocks 3 can be installed on the front side of the connecting plate 2). During installation, align the insertion through hole 301 on the counterweight block 3 with the support rod 201. The counterweight 3 is then pushed backward, allowing the support rod 201 to engage with the insertion hole 301. When the counterweight 3 is pushed to its limit position, two adjacent elastic buckles 403 automatically engage with the inner side of the corresponding snap-fit ​​frame 402, quickly achieving the limiting effect on the counterweight 3. Then, the workers enter the support cage 102. At this time, the support cage 102 and the hanger 101 can maintain a good balance, thus being less susceptible to large swaying and tilting due to external wind disturbances. Under relatively balanced conditions, construction efficiency and quality can be effectively improved, avoiding a major threat to the personal safety of workers due to load imbalance. In addition, even if there is a certain error in the weight between the support cage 102 and the hanger 101 after the counterweight is applied, it still provides an effective weighting effect compared to the traditional structure without counterweight, thus preventing the front of the hanger 101 from easily tilting.

[0021] Next, the staff inside the support cage 102 can carry out inspection and reinforcement work on the side of the bridge. Then, by moving the position of the suspension bracket 1 left and right, the staff can be moved to the corresponding inspection and reinforcement position.
