Description

Technical Field

[0001] The utility model relates to the field of construction safety, in particular to a frame-type movable safety cable device. Background Art

[0002] In the field of bridge capping beam construction, traditional construction methods have many potential safety hazards and inconveniences. Specifically, during the construction process, a crane is usually used to hoist the main beam onto the support frame and hoop, and then the distribution beam is hoisted and the construction platform for the capping beam is erected. During these operations, workers need to hang safety belts to ensure construction safety. However, when not using a dedicated safety mother cable system, workers often can only hang the safety belt on existing structural members or formworks.

[0003] This approach has several deficiencies. First, it is often inconvenient to hang the safety belt on structural members or formworks, and workers need to spend extra time and effort to find suitable hanging points. Second, these hanging points are often not secure enough and there is a risk of detachment, posing a potential threat to the lives of workers. Third, since the hanging points are usually at a relatively low position, the working space of workers is restricted, affecting construction efficiency. Finally, frequently hanging and removing the safety belt will also reduce the working continuity of workers, further affecting the construction progress and efficiency. Summary of the Utility Model

[0004] In order to overcome the above defects in the prior art, a frame-type movable safety cable device is provided, which is applicable to two environments of erecting Bailey trusses or erecting main beams, has strong compatibility, and can suspend safety ropes without changing the original platform structure and without affecting construction efficiency.

The tightening rope is used to enhance the connection rigidity between the column and the main beam, so that the entire frame structure can better maintain its shape and stability when subjected to external forces.

[0011] Preferably, the connection between the column and the fastening rope, and between the main beam and the fastening rope are provided with a single-hole ear bar for fixing the fastening rope. The single-hole ear bar provides a reliable fixing point for the fastening rope through the hole on it; when the fastening rope passes through the hole and is tightened, the single-hole ear bar can ensure that the fastening rope will not fall off or loosen from the connection.

[0012] Preferably, the manual sliding device is provided with a pulley and a moving platform; the moving platform is connected to the crossbeam through the pulley, and the pulley is engaged with the inner groove provided in the crossbeam and moves along the length direction of the crossbeam.

[0028] As Figure 1 shown, the frame-type movable safety cable device is assembled on the main beam 4 and includes a first frame 1, a second frame 2, and a movable main cable assembly 3; the first frame 1 and the second frame 2 serve as the basic support structures of the entire device and are firmly installed on the main beam 4; the two are relatively fixed, providing a stable running track and a support device for the movable main cable assembly 3.

[0029] Among them, the movable main cable assembly 3 includes a steel wire rope 31, a manual sliding device 32, and an anti-falling device 33; the steel wire rope 31 is used to carry and transmit the safety force and has high strength and wear resistance; the anti-falling device 33 is installed on the steel wire rope 31. When an accidental fall occurs, the anti-falling device 33 can quickly lock the steel wire rope 31 to prevent the person from continuing to fall, thereby avoiding or reducing injuries; the steel wire rope 31 is assembled between the tops of the first frame 1 and the second frame 2 through the manual sliding device 32, and the manual sliding device 32 is used to guide the steel wire rope 31 to move in a direction perpendicular to the main beam 4; through the design of the movable main cable assembly 3, the operator can obtain reliable safety protection at any time during high-altitude operations. No matter how the operation position changes, only by simply operating the manual sliding device 32, the safety cable can be adjusted to a suitable position, effectively preventing the occurrence of falling accidents.

[0030] The wire tightener 34 is installed between the manual sliding device 32 and the wire rope 31, and is used to adjust the tightness of the wire rope 31 to ensure its stability and safety during operation. In this embodiment, the wire tightener 34 is a hand wrench, which facilitates the installation and disassembly of the manual sliding device 32 and the wire rope 31, and improves the safety of the movable main cable assembly 3.

[0031] The bottom of the first frame 1 and the second frame 2 is provided with a fixing component 5 for connecting the main beam 4. The fixing component 5 is used to firmly fix the first frame 1 and the second frame 2 on the main beam 4 to prevent displacement or detachment due to external forces during operation. This not only ensures the overall stability of the device, but also ensures that the movable main cable assembly 3 can operate in a stable and reliable environment, thereby further improving the safety of the operation.

[0032] Among them, the structures of the first frame 1 and the second frame 2 are the same; both include two columns 11 and a plurality of cross beams 12; the plurality of cross beams 12 are fixed between the two columns 11, enhancing the overall stiffness of the frame and providing support in the horizontal direction. The two columns 11, as the main load-bearing members of the frame, provide stability in the vertical direction.

[0033] The fixing component 5 includes a backing plate 51 and a U-shaped nail 52. The backing plate 51 is assembled at the bottom end of the column 11, and the U-shaped nail 52 fixes the main beam 4 on the backing plate 51. The backing plate 51 can disperse the pressure generated by the bottom of the column on the main beam 4 to prevent damage caused by local stress concentration. The backing plate 51 is in direct contact with the main beam 4, which can prevent scratches or abrasions on the surface of the main beam 4 caused by the bottom of the column 11. The U-shaped nail 52 is the key fastener in the fixing component 5 and is used to firmly fix the main beam 4 on the backing plate 51.
