[0002] Safety rope is a kind of safety protection equipment used in aerial work, usually woven from synthetic fibers such as polyester, nylon, aramid, etc. Its main function is to serve as a double protection measure, playing the role of support, lifting and braking. In the event of a fall accident, it prevents aerial workers from falling and protects the safety of construction workers. At present, during the installation of the safety rope, construction workers need to use hooks and locks to fix the safety rope on the suspension rope. It can be seen that the safety rope or suspension rope is fixedly connected and the length of the safety rope is limited, which greatly affects the construction workers' range of activities. If the construction height is changed, the locker anchored by the suspension rope needs to be manually loosened. This process will cause the safety rope protection measures to temporarily fail, increasing the risk of working at heights. Utility Model Content

DETAILED DESCRIPTION

[0022] The following is a further detailed description of the implementation of the present utility model in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present utility model, but cannot be used to limit the scope of the present utility model.

[0023] like Figure 1-Figure 8As shown, the utility model provides a safety rope locking device, including a fixing plate 2; the fixing plate 2 is welded to the flip baffle 1; it also includes an adjusting plate 5, a bolt 6, a bearing frame 8, a return spring 9, a connecting rod 10, a guide rod 14, a baffle 15 and a knob 17; the top end of the return spring 9 is welded to the lower side of the fixing plate 2, and the bottom end of the return spring 9 is welded to the upper side of the clamping block 16; the front end of the adjusting plate 5 is hinged with the flip baffle 1, and the outer side of the flip baffle 1 is provided with a through groove; the number of the guide rods 14 is two groups, and the left end face and the right end face of the guide rod 14 are both welded to the connecting frame 3; the bolts 6 and the butterfly The nut 7 is screwed on by threads; the knob 17 is welded and connected to the left side of the threaded rod 4; the threaded rod 4 is connected to the adjusting plate 5 by threaded engagement; two groups of left and right opposite through holes are provided on the connecting frame 3, and the left and right ends of the threaded rod 4 are rotatably connected in the through holes of the connecting frame 3; the upper end of the connecting rod 10 is hinged to the lower side of the clamping block 16, and the bottom end of the connecting rod 10 is hinged to the upper side of the sliding block 11; the bottom end of the sliding block 11 is welded and connected with the hanger 13, and the hanger 13 is rotatably connected to the lifting ring 12; the baffle 15 is welded and connected to the adjusting plate 5; the supporting frame 8 is welded and connected to the flip baffle 1, and the supporting frame 8 is slidably connected to the clamping block 16.

[0024] When installing the safety rope self-locking device of the utility model, the position of the flip baffle plate 1 is first adjusted according to the thickness of the suspension rope, and the knob 17 is manually turned. The knob 17 drives the threaded rod 4 to rotate. Since the positive thread end and the reverse thread on the outer side of the threaded rod 4 are respectively engaged with the threaded through holes of the two groups of adjustment plates 5, the threaded rod 4 drives the two groups of adjustment plates 5 to move in opposite directions along the guide rod 14, changing the closing distance between the flip baffle plates 1, so that the clamping block 16 carried by the flip baffle plate 1 can perform self-locking clamping on the suspension ropes of different thicknesses, and then the two groups of flip baffle plates 1 hinged at the front ends of the two groups of adjustment plates 5 are closed and flipped in opposite directions, and then the butterfly nut 7 is screwed on the bolt 6. The bolt 6 cooperates with the butterfly nut 7 to close and fix the two groups of flip baffle plates 1, so that the suspension rope is embedded between the two groups of flip baffle plates 1, and the installation of the safety rope self-locking device on the suspension rope is completed, and the safety rope is hung When the worker falls, the safety rope is tightened. At this time, the safety rope pulls the hanger 13 downward through the hanger 12, and the hanger 13 pulls the sliding block 11 welded on the upper side to move downward. The two sets of sliding blocks 11 drive the convex columns of the two sets of clamping blocks 16 to slide toward each other along the 45-degree inclined groove of the supporting frame 8 through the connecting rod 10 hinged at the upper end. The clamping block 16 is clamped on the outer side of the suspension rope, and the rough surface of the clamping block 16 is used to increase the contact friction between the clamping block 16 and the suspension rope. When the fall is completed, the self-locking device is automatically anchored on the suspension rope. When the safety rope is in a loose state, the two sets of return springs 9 respectively pull the two sets of clamping blocks 16 to slide upward along the 45-degree inclined groove of the supporting frame 8, so that the clamping block 16 and the suspension rope are in a loose state. The self-locking device can change its position on the suspension rope at will without affecting the range of activities of the high-altitude construction workers.

[0025] In the disclosed embodiment, there are two groups of adjustment plates 5, which are symmetrically distributed on the left and right. A threaded through hole is provided at the center of each group of adjustment plates 5. The threaded rod 4 is connected to the threaded through hole of the adjustment plate 5 by threaded engagement. Two groups of through holes are symmetrically provided on the upper and lower sides of the threaded through hole of the adjustment plate 5. The guide rod 14 is inserted into the through hole of the adjustment plate 5, and the threaded rod 4 drives the adjustment plate 5 to move left and right along the guide rod 14.

[0026] In the disclosed embodiment, a forward threaded end and a reverse threaded end are provided on the outer side of the threaded rod 4, the threaded through hole of the right adjustment plate 5 is meshedly connected to the forward threaded end of the threaded rod 4, and the threaded through hole of the left adjustment plate 5 is meshedly connected to the reverse threaded end of the threaded rod 4, and the threaded rod 4 drives the two groups of adjustment plates 5 to move synchronously in opposite directions, so that the two groups of flip baffles 1 hingedly connected to the two groups of adjustment plates 5 can be moved and adjusted according to the thickness of the rope.

[0027] In the disclosed embodiment, there are two groups of clamping blocks 16, which are symmetrically distributed on the left and right sides. Two groups of convex column structures are symmetrically provided on the left and right sides of each group of clamping blocks 16. The opposite surfaces of the two groups of clamping blocks 16 are provided with rough surfaces. The rough surfaces increase the contact friction between the clamping blocks 16 and the suspension rope. When the clamping blocks 16 clamp the suspension rope, they prevent the clamping blocks 16 from sliding on the outer side of the suspension rope, thereby preventing high-altitude construction workers from falling.

[0028] In the disclosed embodiment, a T-shaped protrusion structure is provided on the outer side of the sliding block 11, and the T-shaped protrusion structure of the sliding block 11 is embedded in the through groove of the flip baffle 1. When the safety rope falls and is pulled, the sliding block 11 slides stably and directionally along the through groove of the flip baffle 1.

[0029] In the disclosed embodiment, two groups of through-groove structures are provided on the supporting frame 8, and the through-groove structures of the supporting frame 8 are inclined at 45 degrees. The convex column structures on the left and right sides of the clamping block 16 are embedded in the through-groove structures of the two groups of supporting frames 8. The clamping block 16 is slidably connected to the supporting frame 8, and the supporting frame 8 controls the sliding path of the clamping block 16 through the oblique path of the through-groove 45, so that the two groups of clamping blocks 16 can slide directionally along the through-groove of the supporting frame 8 under the pulling of the connecting rod 10, thereby completing the locking work of the clamping block 16 on the suspension rope.

[0030] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The bolts 6 and butterfly nuts 7 used above are common components on the market. When you buy them back and use them, you only need to connect them according to the instruction manual purchased together, so I will not repeat them here.

[0031] The technical solution of the present invention is not limited to the scope of the embodiments of the present invention, and the technical contents not described in detail in the present invention are all well-known technologies.
