Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, and specifically relates to a protective device for the construction of guardrails in bridges. Background Technology

[0002] In bridge railing construction, working at heights is a complex process that requires strict adherence to safety regulations. The greatest danger in railing construction comes from working at heights, making it crucial to address the challenges of high-altitude work during bridge railing construction. Bridge railing construction is a high-altitude undertaking, and bridges typically intersect with rural roads, with pedestrians and vehicles passing underneath; therefore, construction safety is of paramount importance.

[0003] The conventional method for high-altitude work during the construction of bridge railings involves erecting a suspended platform on the bridge deck or using aerial work platforms to transport workers to the designated location for construction. The movement of the suspended platform and aerial work platform is cumbersome, leading to frequent adjustments during construction and impacting overall efficiency. Furthermore, since both are high-altitude operations, the weld strength of the suspended platform and the security of the safety cables directly affect the safety of the workers. If the suspended platform has weld defects or the cable connections are weak, it can easily fall, causing serious accidents. Suspended platforms are usually attached to one edge of the bridge, allowing workers to work only on one side. Moving from one platform to another requires a complex process of disassembly, relocation, and reinstallation, significantly reducing construction efficiency. Utility Model Content

[0004] In view of this, the present invention provides a protective device for bridge railing construction, which can solve the problems of inconvenience in quickly changing construction positions and low efficiency in existing bridge railing construction.

[0005] This utility model is implemented as follows:

[0006] This utility model provides a protective device for bridge railing construction, comprising a frame, a connecting platform, a railing, a first ladder, and pulleys. The frame is a rectangular steel pipe welded structure with internal cross supports for overall support. The frame has an inverted U-shaped structure, spanning the bridge's operating platform with its two ends located on the left and right sides of the bridge. The pulleys are located at the bottom of both ends of the frame. The connecting platform is fixedly connected to the top of the frame, and the connecting platform is composed of steel plates and an anti-slip layer, providing operating space for construction personnel. The railing is fixed to the edge of the connecting platform, and the railing consists of vertical posts and horizontal railings, with the railings and posts welded together. A set of first ladders is located in the middle of the frame, and the first ladder consists of two vertical channel steels and connected steps. Foldable second ladders are located on both sides of the frame, and the second ladders are hinged to the side frames of the frame.

[0007] Based on the above technical solution, the protective device for bridge railing construction of this utility model can be further improved as follows:

[0008] The pulleys are omnidirectional wheels, which can rotate flexibly to facilitate the steering and direction adjustment of the frame, and are equipped with braking devices.

[0009] Furthermore, the posts of the guardrail are made of square tubing, the base is made of steel plate, and the railings are made of round tubing, all of which are made of Q235 steel.

[0010] Furthermore, the height of the guardrail is greater than 1.2 meters.

[0011] Furthermore, the guardrail is equipped with a safety net to further enhance the protective effect and prevent tools or materials from falling off the platform.

[0012] Furthermore, the safety net is made of high-strength nylon.

[0013] Furthermore, the steps of the first ladder are made of anti-slip patterned steel plates.

[0014] Furthermore, the surface of the vehicle frame is treated with anti-rust paint to improve its corrosion resistance.

[0015] Furthermore, the frame uses rectangular steel tubing with a diameter of 50mm and a wall thickness of 3mm, made of Q235 steel.

[0016] Furthermore, the thickness of the patterned steel plate is 3mm.

[0017] Compared with the prior art, the beneficial effects of the protective device for bridge guardrail construction provided by this utility model are: 1. The guardrail set on the top of the frame can effectively prevent construction workers from falling from a height due to accidents during the operation, thus ensuring the personal safety of construction workers.

[0018] 2. Traditional construction methods may require construction workers to work in mid-air on the outside of the bridge, while this type of vehicle allows construction workers to operate on a relatively safe platform, avoiding the dangers of working at height.

[0019] 3. The structural design of this device enables it to remain stable during construction, providing a stable working environment for construction personnel and reducing safety hazards caused by platform swaying.

[0020] 4. The vehicle frame moves parallel to the other side of the bridge by means of pulleys, and can quickly move to the designated position on the bridge without frequent disassembly and re-erection, which greatly saves construction time and manpower.

[0021] 5. The use of this device reduces the risks to construction workers operating at heights and lowers compensation costs due to safety accidents. At the same time, its high construction efficiency reduces labor input and saves on labor costs.

[0022] 6. The structure is relatively simple, making maintenance and upkeep more convenient, reducing repair difficulties caused by complex structures, and lowering equipment wear and maintenance costs.

[0023] 7. Since the vehicle frame spans both sides of the bridge, workers can move directly from one side to the other using the trolley to perform side operations without having to detour frequently, which greatly saves time and improves construction efficiency. Attached Figure Description
