Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

The utility model discloses a self-rolling and locking safety rope and a high-altitude work safety belt with the self-rolling and locking safety rope. Using the high-altitude work safety belt with self-winding and locking safety rope when working at high altitude can ensure the convenience of use and the use experience is better. The following are specific examples:

The self-winding and locking safety rope of the utility model improves the existing single safety rope. As shown in FIG. 1 , it includes a twist rope segment 1 and a webbing segment 2 connected to each other and a retractor 3 for retracting the webbing segment 2 . Under this setting, the twist rope section 1 can be set relatively short, usually 1.0m-1.5m; the length of the ribbon section is usually 0.3m-0.5m. The webbing segment 2 is usually in a recovered state in the retractor 3, and can be pulled out from the retractor 3 when needed. Because the webbing segment 2 is recovered in the retractor 3, the length of the safety rope is smaller than that of the safety rope in the prior art under normal conditions, thus avoiding the carrying action of the safety rope due to being too long Inconvenience and the possible influence of body winding may cause inconvenient movement during construction. When needed, the webbing segment 2 can be pulled out from the retractor 3 to meet the length of the safety rope in normal use. In a specific implementation, the twist rope section 1 and the webbing section 2 are connected by a hard ring, that is, the end of the twist section 1 and the end of the webbing section 2 are connected to a hard ring at the same time, through the hard ring Connect the two.

In the utility model, one end of the twisted rope section 1 is provided with a safety hook 4 and the other end is connected with the ribbon section 2, and one end of the ribbon section 2 is connected with the twisted rope section 1 and the other end is wound in the retractor 3. A webbing outlet 5-1 is provided on one side of the retractor 3, and a safety hook 4 is provided on the opposite side of the retractor 3. Two safety hooks 4 are all used to articulate with safety belts. The specific structure is shown in Figure 1 and Figure 2.

The retractor 3 in the utility model can realize the self-rolling locking of the safety rope, specifically, the ribbon section 2 can realize the self-rolling locking. As shown in FIG. 3 , the retractor 3 includes a cylindrical cavity housing 5 and a reel 6 coaxially arranged in the cavity housing 5 . A pre-tension spring is arranged in the reel 6, so that the self-winding of the webbing section 2 can be realized under the action of the pre-tension spring, and the pre-tension spring is a helical spring. As shown in Fig. 4 and Fig. 5, pawls 7 are set on the edge of the end of the reel 6, and a number of ratchets 8 cooperating with the pawls 7 are set on the inner wall of the cavity housing 5 at the same time. and ratchet 8 to realize the locking of the webbing section. As shown in Figure 4, the claw portion of the pawl 7 is just aligned with the edge of the reel 6, and the middle section of the pawl 7 is connected with the end face of the reel 6 by a pin 10, and the pawl 7 can rotate around the pin 10; The tail of the ratchet 7 is provided with a return spring 9 that can keep the ratchet 7 stable. One end of the return spring 9 is connected to the tail of the ratchet 7 and the other end is connected to the end face of the reel 6 . Under the effect of return spring 9, ratchet 7 is kept stable. The locking process of the retractor 3 is as follows: when it is necessary to pull out the webbing section 2 to lengthen the safety rope for easy use, pull the webbing section 2 outwards at a normal speed, and the pawl 7 remains stable under the action of the return spring 9. Can act with ratchet 8, webbing segment 2 is pulled out. When the staff is in danger of falling, the webbing section 2 is accelerated and pulled out, and the pawl 7 swings outward under the action of centrifugal force, which will cooperate with the ratchet 8 on the inner wall of the cavity housing 5 to lock, thereby realizing Protection of Workers. When the danger is removed, manually transport the webbing segment 2 to the retractor 3, the reel 6 rotates in the opposite direction, and under the action of the return spring 9, the ratchet 7 and the ratchet 8 are disengaged, and the pre-tension spring in the reel 6 drives the reel 6 Recycle the webbing section 2.

In order to ensure the reliability of the self-winding locking function of the retractor 3 on the safety rope, especially the reliability of the locking function, pawls 7 are usually arranged at both ends of the reel 6, and the pawls 7 at both ends of the reel 6 At the same time, the function can ensure the reliability of the retractor 3 and the safety of the safety rope.

The utility model also provides a high-altitude work safety belt with a self-winding and locking safety rope, that is, the high-altitude work safety belt is provided with the above-mentioned self-winding and locking safety rope. The high-altitude work safety belt includes a safety belt body with a back belt 11 and a waist belt 12, and the safety rope is connected to the safety belt body using a safety hook. Specifically, the safety hook of the twisted rope section 1 is articulated with the waist belt 12, and the safety hook on the retractor 3 is articulated with the strap 11. This setting can make the self-winding and locking safety rope play its role to the greatest extent. Specifically shown in Figure 6.

In the utility model, the safety rope is set as a twist rope section and a webbing section, and the webbing section is retracted by a retractor, so that the safety rope can be self-rolled and locked, which meets the safety requirements of high-altitude operations and the needs of easy use.

The safety rope of the utility model is short in normal state, easy to carry, does not affect the normal movement of the staff, can be stretched according to needs in the working state, and is more convenient to use.

The retractor in the utility model is provided with matching pawls and ratchets, and triggers the cooperation of the pawls and ratchets through centrifugal action, which is suitable for the situation of sudden falling during high-altitude operations, and can ensure the reliability of the retractor work , so as to ensure the safety of the safety rope.

The safety rope and safety belt for aerial work of the utility model are simple in structure, convenient to carry and use, good in safety and good in comprehensive performance.
