Description

Technical Field

[0001] This utility model relates to the technical field of safety anti-fall devices, specifically a safety anti-fall device for bridge construction in road and bridge development. Background Technology

[0002] A bridge generally refers to a structure erected across rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also been extended to refer to structures built across mountains, challenging geological conditions, or to meet other transportation needs, making travel more convenient. Bridge construction refers to the process of building a bridge according to its design; it mainly includes bridge construction technology, organization, management, and quality control. During bridge construction, falling debris and tools can easily cause safety accidents. Therefore, a bridge construction safety anti-fall device is needed. An existing bridge construction safety anti-fall device (Announcement No.: CN222275264U) has the following disadvantages in use:

[0003] During use, the protective netting is extended by pulling it. When the rising frame reaches the top, the netting fully extends to prevent workers' tools from falling and injuring pedestrians, and also to prevent falling stones from injuring pedestrians during construction. However, when the netting is not extended, it is located around the rising frame, making it difficult for workers to enter the frame to work. Furthermore, when retracting, the netting rotates upwards, and stones and tools inside the netting can easily get stuck inside the rising frame, making it difficult to retract the netting completely and affecting the use of the equipment. Therefore, this patent proposes a safety anti-fall device for bridge construction in road and bridge development to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a safety anti-fall device for bridge construction in road and bridge building, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a bridge construction safety anti-fall device for road and bridge construction, comprising a base, a guardrail fixed to the top of the base, a protective door installed on one side of the guardrail, multiple fixing blocks fixed to the bottom of the base, a rotating plate rotatably connected inside the fixing blocks, an installation opening inside the rotating plate, a protective net installed inside the installation opening, rotating rods rotatably connected to the inner walls of the base, a winding seat fixed to the outer wall of the rotating rods, a rope wound inside the winding seat, and a fixing member fixed to the side of the rotating plate, the rope being fixed to the fixing member.

[0006] Preferably, a guardrail is fixed to the front of the rotating plate, and a baffle is rotatably connected to the bottom of the rotating plate, with a buckle installed between the baffle and the guardrail.

[0007] Preferably, a mounting bracket is fixed to the back of the protective net, the mounting bracket is inserted into the mounting port, and multiple screws are screwed between the mounting bracket and the rotating plate.

[0008] Preferably, the railings and baffles form a square shape.

[0009] Preferably, a support base is fixed to the bottom of the base, and the rotating plate is located around the support base.

[0010] Preferably, a mounting plate is installed at the bottom end of the support base, and mounting holes are installed on the mounting plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By rotating the boom, the rope is drawn into the reel, and the rope drives the rotating plate to rotate upward within the fixed block, thus bringing the plate to a horizontal position to protect the construction site and prevent debris and tools from falling from a height and causing safety accidents. In addition, when the workers finish construction, the boom is reversed to release the rope, and the plate rotates downward within the fixed block under the action of gravity, making it easier for workers to get off the base without being obstructed, and allowing debris and tools on the protective net to fall more effectively without affecting the rotation of the plate.

[0013] In addition, by setting up guardrails and baffles, debris and tools falling into the protective net can be blocked, preventing them from rolling off the net when it is horizontal and causing safety accidents. Furthermore, the protective net is replaceable. When the net is damaged, it can be removed. To remove it, simply take off the screws, remove the net, insert the new net into the installation opening, and screw the screws between the mounting bracket and the rotating plate to secure it.

[0019] 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.

[0020] A bridge generally refers to a structure erected over rivers, lakes, or seas to allow vehicles and pedestrians to pass smoothly. To adapt to the rapidly developing modern transportation industry, the term "bridge" has also come to refer to structures built across mountains, challenging geological conditions, or to meet other transportation needs, making travel more convenient. Bridge construction refers to the process of building a bridge according to its design; it mainly includes bridge construction technology, organization, management, and quality control. During bridge construction, falling debris and tools can easily cause safety accidents, necessitating a bridge construction safety device to prevent falls.

[0021] like Figures 1-4 As shown, this utility model provides a technical solution: a bridge construction safety anti-fall device for road and bridge construction, including a base 2, a guardrail 16 fixed to the top of the base 2, a protective door 15 installed on one side of the guardrail 16, multiple fixing blocks 3 fixed to the bottom of the base 2, a rotating plate 4 rotatably connected inside the fixing blocks 3, an installation opening in the rotating plate 4, a protective net 5 installed in the installation opening, rotating rods 6 rotatably connected to the inner walls of the base 2, a motor corresponding to each rotating rod 6 installed inside the base 2, the output end of the motor passing through the base 2 and fixed to the rotating rod 6, a winding seat 7 fixed to the outer wall of the rotating rod 6, two winding seats 7 fixed to the outer wall of each rotating rod 6, a rope 8 wound inside the winding seat 7, a fixing member 9 fixed to the side of the rotating plate 4, and the rope 8 fixed to the fixing member 9.

[0022] It is important to note that by starting the motor, the motor drives the rotating rod 6 to rotate, which in turn retracts the rope 8 into the take-up seat 7. The rope 8 then drives the rotating plate 4 to rotate upward within the fixed block 3, thus bringing the rotating plate 4 to a horizontal position. This protects the construction site and prevents gravel and tools from falling from a height and causing safety accidents. After the workers finish construction, starting the motor causes the rotating rod 6 to reverse, releasing the rope 8. Under the influence of gravity, the rotating plate 4 rotates downward within the fixed block 3, making it easier for workers to descend from the base 2 without being obstructed. Gravel and tools on the protective net 5 can also fall more effectively without affecting the rotation of the rotating plate 4. A ladder can be installed on the side of the base 2 for workers to access the site.

[0023] like Figure 2 , Figure 3 and Figure 4As shown, a guardrail 10 is fixed to the front of the rotating plate 4, and a baffle 11 is rotatably connected to the bottom of the rotating plate 4. A buckle 12 is installed between the baffle 11 and the guardrail 10. A mounting bracket 13 is fixed to the back of the protective net 5. The mounting bracket 13 is inserted into the mounting opening, and multiple screws 14 are screwed between the mounting bracket 13 and the rotating plate 4. The guardrail 10 and the baffle 11 form a U-shape.

[0024] It should be noted that by setting up the guardrail 10 and baffle 11, the debris and tools falling into the protective net 5 are blocked, preventing the debris and tools from rolling off the protective net 5 when it is in a horizontal state and causing a safety accident. In addition, the protective net 5 can be replaced. When the protective net 5 is damaged, it can be removed. To remove it, simply remove the screw 14, then take out the protective net 5, insert the new protective net 5 into the installation port, and screw the screw 14 between the mounting bracket 13 and the rotating plate 4 to fix it.

[0025] like Figure 1 As shown, a support base 1 is fixed to the bottom of the base 2, and a rotating plate 4 is located around the support base 1. A mounting plate is installed at the bottom of the support base 1, and mounting holes are installed on the mounting plate.

[0026] It should be noted that the electrical components in this solution are controlled by their associated peripheral controller, and the control circuit can be easily programmed by those skilled in the art, belonging to common knowledge in the field. This is merely a use of the existing circuit without any modification. Furthermore, this utility model is primarily used to protect mechanical devices, so the control method and circuit connections will not be explained in detail. A mounting plate is installed at the bottom of the support base 1, allowing the support base 1 to be mounted on an existing lifting device, thus raising and lowering the base 2. Additionally, when personnel are not inside the base 2, the protective net 5 is in a vertical position. The controller can be installed on the base 2 or at a location convenient for workers. The operator enters the base 2 and starts the motor by activating the external controller, which keeps the protective net 5 in a horizontal position for protection. After the work is completed, the lifting device moves the base 2 downward. When it reaches a low position, the protective net 5 is not far from the ground. The motor is then activated by the controller, and the protective net 5 moves to a vertical position. The gravel and tools on the protective net 5 fall from inside the protective net 5 and onto the ground. Since the gravel and tools will not fall from a high place, it avoids safety hazards. In addition, some gravel or tools are blocked by the baffle 11. The baffle 11 can be opened by opening the buckle 12, allowing the gravel inside the protective net 5 to fall.

[0027] 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 embodiments and their equivalents.
