Description

Technical Field

[0001] The utility model relates to the technical field of construction protection devices, in particular to a safety protection device for workers in the installation process of a power plant. Background Art

[0002] During the installation of power plants, power workers often need to climb up some very high poles to perform their work. These poles are usually more than ten meters high, and some are even more than twenty meters high. Such high-altitude work poses a great threat to the health and safety of workers.

[0003] In actual operation, in order to ensure the personal safety of power workers, we usually wear safety belts on the workers and connect them to the poles through safety ropes. In this way, even if an unexpected situation occurs, the workers can rely on the safety protection measures of the safety belts and safety ropes to ensure their life safety. However, since the surface treatment of the poles is often not completely anti-slip, the safety ropes can easily slide down from the poles, posing a safety hazard to the workers.

[0004] In summary, the inventors believe that in order to further ensure the safety of electric workers during high-altitude installation, it is necessary to further improve and perfect the existing safety protection devices. Utility Model Content

[0029] See also Figure 1-4 , a worker safety protection device during power plant installation, comprising

[0030] The fixing ring 1 is composed of two semicircular half hoops 2. The two half hoops 2 are put together to be fixed on the side of the electric pole 3. Specifically, one end of the two half hoops 2 is connected with a connecting shaft 7, and the other end of the two half hoops 2 is connected with a connecting bolt 8. When installing, the two half hoops 2 are rotated to open, and after the half hoops 2 are put on the electric pole 3 from the side, the half hoops 2 are closed, and the half hoops 2 are fixed by the connecting bolt 8, so that the device is fixed on the electric pole 3;

[0031] The number of the protective rods 4 is at least 3, one end of which is fixed with a shaft 41, and is rotatably mounted on the side of the fixing ring 1 through the shaft 41. When not in use, the protective rod 4 can be folded, and the length direction after folding coincides with the axial direction of the fixing ring 1, so as to facilitate carrying. When in use, the protective rod 4 is rotated and unfolded so that it and the fixing ring 1 are on the same horizontal plane to form a support surface;

[0032] The protection net 5 is connected between adjacent protection poles 4 to play a protective role. When the electrician accidentally slips from the electric pole 3, the protection net 5 can catch the electrician and reduce the injury.

[0033] The support rod 6 is folded and connected to the other end of the protection rod 4 connected to the fixing ring 1. When not in use, the support rod 6 is folded on the side of the protection rod 4 and then rotated and stored together with the protection rod 4. When in use, the support rod 6 is unfolded and supported on the ground.

[0034] The following is a specific embodiment of the support rod 6, which includes a rotating rod 61, a telescopic rod 62 and a buffer spring 63. A second shaft 610 is fixed to one end of the rotating rod 61. The rotating rod 61 is rotatably connected to the end of the protective rod 4 away from the fixed ring 1 through the second shaft 610. The upper end of the telescopic rod 62 is slidably connected to the lower end of the rotating rod 61. The buffer spring 63 is connected between the lower end of the rotating rod 61 and the upper end of the telescopic rod 62. When the electrician accidentally falls, the fixed ring 1 may not be enough to support him, so it can play a buffering role when the support rod 6 is retracted;

[0035] It is worth mentioning that the protective device also includes a transmission structure, which is connected between the shaft 1 41 and the shaft 2 610 for transmission. The transmission structure includes a driving gear 411, a transmission gear 412, a sprocket mechanism 413 and a steering gear 414. The driving gear 411 is fixedly connected to one end of the shaft 1 41, and the transmission gear 412 and the steering gear 414 are rotatably installed on the side of the fixed ring 1. The two sides of the steering gear 414 are respectively meshed with the driving gear 411 and the transmission gear 412. The sprocket mechanism 413 is connected between the shaft portion of the transmission gear 412 and the shaft 2 610 for transmission. When the protective rod 4 is rotated to open, the shaft 1 41 drives the driving gear 411 to rotate, the driving gear 411 drives the steering gear 414 to rotate, and the steering gear 414 rotates to drive the transmission gear 412 to rotate. The transmission gear 412 drives the shaft 2 610 to rotate through the sprocket mechanism 413, so that the rotating rod 61 is rotated, and the support rod 6 is also rotated and opened together for easy use.

[0036] A first fixing bolt 9 is connected between the protection rod 4 and the fixing ring 1 for fixing the angle when the protection rod 4 is unfolded.

[0037] A second fixing bolt 64 is connected between the rotating rod 61 and the protection rod 4 , and is used to fix the rotating rod 61 perpendicular to the ground when the supporting rod 6 supports the ground.

[0038] In order to facilitate the movement of the device, a roller 65 is installed at the lower end of the support rod 6. When the device is fully unfolded, the setting of the roller 65 makes it convenient to push the device to move. When it moves to the position of the telephone pole 3, the half hoop 2 is unfolded and fixed on the side of the telephone pole 3.

[0039] One end of the half hoop 2 connected by the connecting bolt 8 is a free end, one side of the protective net 5 corresponding to the free end is fixedly connected to the protective rod 4 at the corresponding position, and the other side of the protective net 5 corresponding to the free end is detachably connected to the protective rod 4 at the corresponding position. The setting of the free end is to facilitate the installation of the fixing ring 1 on the electric pole 3, and the detachable connection method can be a connecting hook method.

[0040] A rubber pad 10 is fixed to the inner surface of the half hoop 2 .

[0041] Working principle: When the utility model is used, the protective rod 4 on the side of the fixed ring 1 is rotated to unfold. When the protective rod 4 is unfolded, the support rod 6 is automatically opened through the transmission mechanism, and is supported on the ground by the roller 65 at the lower end of the support rod 6, so that one end is convenient, and then the device is pushed to move to the position of the electric pole 3. When the power workers climb up the electric pole 3 to carry out power construction, the construction workers on the ground can fix the fixed ring 1 to the electric pole 3, so that the protective net 5 forms a complete protective structure near the bottom of the electric pole 3, thereby further improving safety.

[0042] The embodiment and drawings of the present utility model are only for illustrating the design concept of the present utility model, and the protection scope of the present utility model should not be limited to this embodiment.

[0043] It can be seen from the above description that the design purpose of the utility model can be effectively implemented. The embodiment part shows the purpose of the utility model and the implementation function and structural theme, and includes other equivalent replacements.

[0044] Therefore, the rights of the present utility model include other equivalent implementations, and the specific scope of rights is referred to the claims.
