Description

Technical Field

[0001] The utility model relates to the technical field of clamping, in particular to a clamping device for hanging a safety rope on a slope. Background Art

[0002] Safety belts are essential protective equipment for aerial work. It is understood that in the industrial production process, the rate of casualties caused by human falls is quite high. According to statistical analysis, casualties caused by human falls account for about 15% of industrial accidents.

[0003] Since the degree of injury from falling is related to the height of the fall, in general, all countries use operations above 2m (including 2m) above the reference plane as high-altitude operations, and stipulate that personal protective measures need to be taken. In this way, the role of the safety belt is very obvious. It allows operators to work safely at heights, and in the event of an accident, it can also effectively avoid the huge damage to the human body caused by falling. However, when performing slope operations, there is often a lack of more reliable safety belt hanging points on the completed lattice beams or arched beams. Therefore, it is particularly important to provide a safety rope fixing device for slope high-altitude operations.

[0004] The existing safety rope fixing device is usually clamped on both sides of the slope in a clamping manner. For example, the utility model patent with the publication number CN217631441U records a simple slope construction safety rope fixing device, including: a handle, a clamping assembly and a connecting ring. The handle is in the shape of a long round tube. The clamping assembly is connected to the end of the handle, and the clamping assembly includes two clamping arms, both of which extend in a direction perpendicular to the handle, and a clamping space is formed between the two clamping arms. The connecting ring is connected to the clamping assembly or the handle, and the connecting ring is used to connect the safety rope. In this device, the size of the clamping space between the two clamping arms can be easily adjusted by sliding the column and the tube body, and the fastener is inserted into the first fixing hole for fixing. However, in this way, the adjustment of the clamping space can only be determined by the number of spacings of the first fixing hole, and the adjustment range is limited. When one side of the slope is an inclined surface, the clamping arm cannot adapt to the inclined surface and cannot be safely clamped. In view of this technical problem, the utility model provides a clamping device for hanging a safety rope on a slope. Utility Model Content

Compared with the existing connection through screws and screw holes, its adjustment is more convenient and the adjustment range is wider. In addition, since the clamping mechanism 2 is rotatably connected, it can adapt to different slope inclinations.

[0024] A further solution of this embodiment is that one end of the U-shaped rod 1 and one end of the horizontal screw rod 3 are both provided with a ball foot 7, and the ball foot 7 is rotatably connected to the clamping mechanism 2. More specifically, the clamping mechanism 2 includes a clamping seat 2c and a limit sealing plate 2f.

The limit sealing plate 2f passes through the ball foot 7 and is connected to the clamping seat 2c by a first screw 2e. A circular through hole is provided on the limit sealing plate 2f. The diameter of the circular through hole needs to be larger than the diameter of the horizontal screw rod 3 or the bending section of the U-shaped rod 1 and smaller than the diameter of the ball foot 7, so that the clamping seat 2c can be universally rotated within a certain range.
