Description

Technical Field

[0001] The utility model relates to an auxiliary support device for a safety belt lifeline, belonging to the technical field of lifeline erection. Background Art

[0002] Working at heights is one of the dangerous activities that is often carried out in life. If there are no safe, reliable, flexible and practical anti-falling facilities, it will lead to a significant reduction in work efficiency or pose a huge threat to the personal safety of workers. In construction projects, when scaffolding is erected, scaffolders usually first set up a lifeline, and then hang the safety hook on the safety belt on the lifeline to ensure the safety of the work and prevent falling. When the lifeline is long, the middle part is easy to sag. In order to facilitate the work and ensure the safety of construction, the workers usually use fasteners and other measures to fix the sagging part of the lifeline on the vertical pole of the scaffolding. When the worker wearing a safety belt moves the work surface and encounters the fixed position of the lifeline, it is necessary to remove the safety hook first, then cross the fixed point and hang it on the next section of the lifeline. This operation process directly increases the safety risk of the workers and also reduces work efficiency. How to enable the workers to move at high altitude without removing the hook, so that the safety belt hook can slide uninterruptedly on the lifeline throughout the whole process to improve the safety and efficiency of the work process is the research and development purpose of this solution.

[0020] Combine the following Figures 1 to 8 The embodiments of the utility model are described in detail.

[0021] The auxiliary support device for the safety belt lifeline includes a fastener 2 buckled on a steel pipe 1, and is characterized in that: the fastener 2 has a connecting rod 3 perpendicular to the steel pipe 1, and the connecting rod 3 is sequentially equipped with a limit plate 4 and a rotatable impeller 5 for limiting the upward movement of the lifeline, the lifeline 6 is supported on the impeller 5, the limit plate 4 extends above the lifeline 6, and the impeller 5 rotates on the connecting rod 3 as the safety belt hook passes.

[0022] The safety belt lifeline auxiliary support device described above, the fastener 2 is fastened to the steel pipe 1 at the drooping position of the lifeline, the lifeline 6 is supported on the impeller 5, and the limit plate 4 extends above the lifeline 6. The limit plate 4 can prevent the lifeline 6 from moving and being offset from the impeller 5, resulting in the inability to support the impeller 5, ensuring that the lifeline 6 and the impeller 5 do not separate during the sliding of the safety belt hook on the lifeline. When the safety belt hook slides to the impeller 5 position, the safety belt hook enters the impeller 5 along the lifeline 6 to push the impeller 5 to rotate, so that the safety belt hook passes through the impeller 5 and slides to the next section of the lifeline 6, realizing the full sliding of the safety belt hook on the lifeline 6 without being removed, thereby reducing the risk of high-altitude operations. The safety belt lifeline auxiliary support device described has a simple structure and is easy to install on a steel pipe. The operation of the safety belt hook passing through the impeller is simple and does not increase the difficulty of sliding the safety belt hook, which is convenient for high-altitude operators to operate, improves work efficiency, and is highly practical.

[0023] The impeller 5 includes a central tube 51 and blades 52 integrally formed on the outer periphery of the central tube 51. The blades 52 are divided into two layers. A bearing 53 is pressed into the central tube 51. The bearing 53 is sleeved on the connecting rod 3. The lifeline 6 is supported on the central tube 51 and located between the two layers of blades 52. As shown in the figure, the impeller 5 has two layers of blades 52. The bearing is pressed into the central tube 51. The bearing 53 is sleeved on the connecting rod 3 so that the impeller 5 can rotate smoothly on the connecting rod 3. The lifeline 6 is supported on the central tube 51. The two layers of blades limit the forward and backward movement of the lifeline 6. The upward movement of the lifeline 6 is limited by the limit plate 4, the forward and backward movement is limited by the two layers of blades 52, and the drooping is limited by the central tube 51, so as to ensure that the lifeline 6 will not be separated from the impeller 5. When the safety belt hook passes through the impeller 5, it only needs to slide along the lifeline. During the sliding process, the safety belt hook contacts the blade 52 to drive the impeller 5 to rotate, and it can smoothly pass through the impeller 5 and slide to the next section of the lifeline.

[0024] The connecting rod 3 is composed of a bare rod section 31 and a screw rod section 32 with external threads, the limit plate 4 and the bearing 53 are sleeved on the bare rod section 31, and the screw rod section 32 is equipped with a nut 7. The nut 7 does not press the impeller 5 and does not affect the rotation of the impeller 5. The nut 7 is used to prevent the impeller 5 from falling off the connecting rod 3.

[0025] The limiting plate 4 has a circular hole 41 opposite to the connecting rod 3, and the limiting plate 4 is sleeved on the connecting rod 3 through the circular hole 41. The limiting plate 4 has a protruding foot 42 parallel to the connecting rod 3 and located above the lifeline. The protruding foot 42 is located above the lifeline 6 to limit the upward movement of the lifeline 6, so as to prevent the lifeline 6 from moving upward and then moving forward and separating from the impeller 5.

[0026] There are two protruding legs 42, the distance between the two protruding legs 42 is greater than the outer diameter of the impeller 5, and the impeller 5 is located between the two protruding legs 42. The protruding legs 42 limit the upward movement of the lifeline 6 so that the lifeline 6 will not be separated from the impeller. The impeller 5 is located between the two protruding legs 42 to avoid the protruding legs 42 interfering with the rotation of the impeller 5, thereby ensuring that the impeller 5 can rotate smoothly under the push of the safety belt hook.

[0027] When using the safety belt lifeline auxiliary support device described above, firstly fasten the fastener 2 to the steel pipe 1 at the drooping position of the lifeline, and then put the limit plate 4 and the impeller 5 on the connecting rod 3 in sequence, and then screw the nut 5 on the connecting rod 3; then, support the drooping lifeline on the central tube 51, and be located below the extended foot 42 and between the two layers of fan blades 52; when the safety belt hook slides to the position of the impeller 5, it slides along the lifeline 6 and contacts the fan blades 52, pushing the impeller 5 to rotate, and the safety belt hook smoothly passes through the impeller 5 and slides to the next section of the lifeline. The safety belt hook does not need to be removed during the entire sliding process on the lifeline 6, ensuring that the safety belt hook is connected to the lifeline hook throughout the entire process, reducing the risk of high-altitude operations and improving work efficiency.
