Description

Technical Field

[0001] The utility model relates to the technical field of safety rope fixing, in particular to a safety rope fixing device for a scaffold. Background Art

[0002] At present, municipal projects such as water treatment plants and bridges mostly use steel tube scaffolding, and the steel wire rope is fixed on the scaffolding to ensure the fixation of the safety rope. The safety rope is a rope used to protect the safety of personnel and objects during high-altitude operations. The safety rope is woven with synthetic fibers, hemp ropes or steel wire ropes. It is an auxiliary rope used to connect safety belts. It is suitable for field electricians, construction workers, telecommunications workers, wire maintenance and other similar jobs; the safety rope can reduce the actual impact distance when a fall occurs, and the safety lock and steel wire rope work together to form a self-locking device to prevent the working rope of the hanging basket from breaking and causing a high-altitude fall. The use of safety ropes and safety belts in combination can ensure that people will not fall. Accidents happen in an instant, so safety ropes and safety belts must be fastened as required when working at heights;

[0003] However, the existing safety rope fixing device simply connects the clamp to the scaffolding cross pipe and fixes it by bolts, which may cause the bolts to loosen when the clamp collides and slides during use, posing certain safety hazards. Therefore, we propose a safety rope fixing device for scaffolding. Utility Model Content

[0004] The utility model aims to provide a safety rope fixing device for a scaffold.

[0005] In order to solve the problems raised in the above-mentioned background technology, the utility model provides the following technical solutions: a safety rope fixing device for a scaffold, comprising a first clamp, a rotating column is installed on the inner wall of the first clamp near the lower side, a second clamp is installed on the right side of the rotating column, a first nut is installed on the right side wall of the second clamp, a limiting plate is provided on the outer wall of the first nut, a sliding plate is installed on the outer wall of the limiting plate, and a first threaded column is installed on the inner wall of the first nut.

[0006] Preferably, a rotating cylinder is fixedly connected to the left side wall of the first threaded column, and the rotating cylinder is located on the upper side of the inner side wall of the first clamp.

[0007] Preferably, a bolt is provided through the upper end of the slide plate, and the bolt passes through the limiting plate.

[0008] Preferably, a rotating shaft is provided through the front side of the first clamp, and the rotating shaft passes through the rotating column and the rotating cylinder respectively.

[0009] Preferably, an auxiliary fixing bracket is installed on the left side wall of the first clamp, a second threaded column is installed on the inner side wall of the auxiliary fixing bracket, a second nut is arranged on the left side of the outer side wall of the second threaded column, a connecting tube is arranged at the center position of the outer side wall of the second threaded column, a first blade and a second blade are respectively installed on both sides of the connecting tube, and a steel wire rope is installed on the inner side wall of the first blade.

[0010] Preferably, the first blade and the second blade respectively adopt a steel hexagonal turntable blade structure.

[0011] Preferably, the inner side walls of the first blade and the second blade are both provided with notches, and a fixing ring is installed on the right side wall of the second nut.

[0012] By adopting the above technical scheme, the connection between the slide plate and the limiting plate is cancelled by loosening the bolt, and then the limiting plate is removed, and then the first nut is rotated to eliminate the fixation of the first nut to the first threaded column, and then the first threaded column is pulled to make the first threaded column rotate inside the first hoop with the cooperation of the rotating cylinder and the rotating shaft, and then the second hoop is rotated through the cooperation of the rotating column and the rotating shaft to eliminate the closure of the second hoop to the first hoop, and then the first hoop is connected to the scaffolding cross tube, and then the second hoop is rotated again to make the second hoop close the first hoop again, and then the first nut is rotated to connect the first threaded column and the second hoop, and then the cooperation of the limiting plate, the slide plate and the bolt prevents the first nut from rotating during collision and sliding, and prevents the first nut from detaching from the first threaded column, thereby improving the safety of the safety rope fixing device for the scaffolding.

[0013] By adopting the above technical scheme, the second nut is rotated to make the clamping of the first blade by the second nut disappear, and then the first blade is moved to the left to increase the distance between the first blade and the second blade, and then the wire rope is put in. At this time, the second nut is rotated again to make the second nut clamp the wire rope through the first blade and the second blade. At the same time, because the first blade and the second blade are both hexagonal turntable blade structures, and the middle notch position of the hexagon of the blade is just used for temporary accommodation when the safety lock buckle passes through, when the safety lock buckle reaches the supporting point of the wire rope, the first blade is rotated to make the first blade drive the second blade to rotate through the cooperation of the connecting tube, so that it can pass through, and then through the cooperation of the fixing ring and the notch, the clamping of the first blade by the second nut and the clamping of the wire rope by the first blade and the second blade are respectively made more stable, so that the safety rope fixing device for the scaffolding does not need to lift the wire rope or unlock the safety lock buckle, and can safely and quickly pass through the supporting point of the wire rope.

[0025] When in use, the bolt 9 is loosened to disengage the bolt 9 from the slide plate 8, thereby canceling the connection between the slide plate 8 and the limiting plate 7, and then the limiting plate 7 is slid out of the slide plate 8 and removed, so that the restriction of the limiting plate 7 on the first nut 4 is canceled, and then the first nut 4 is rotated to disengage the first nut 4 from the first threaded column 5, and the connection between the first threaded column 5 and the second hoop 3 disappears, and then the first threaded column 5 is pulled to make the first threaded column 5 drive the rotating cylinder 6 to rotate inside the first hoop 1 through the rotating shaft 10, and then the second hoop 3 is pulled to make the second hoop 3 drive the rotating column 2 to rotate inside the first hoop 1 through the rotating shaft 10, so that the second hoop 3 The closure of the first hoop 1 by the second hoop 3 disappears, and then the first hoop 1 is connected to the scaffolding cross pipe, and then the second hoop 3 is rotated again to make the second hoop 3 close the first hoop 1 again, and then the first threaded column 5 is rotated to make the first threaded column 5 inserted into the second hoop 3, and then the first nut 4 is rotated to connect the first threaded column 5 and the second hoop 3, and the limiting plate 7 is inserted into the slide plate 8, and the bolt 9 is rotated to fix the limiting plate 7 with the bolt 9, so that the limiting plate 7 limits the first nut 4, so that the first nut 4 will not rotate during collision and sliding, and the first nut 4 will not be separated from the first threaded column 5.

[0026] Embodiment 2:

[0027] See also Figure 1-4 The utility model provides a technical solution: a safety rope fixing device for a scaffold, an auxiliary fixing bracket 11 is installed on the left side wall of the first clamp 1, a second threaded column 12 is installed on the inner side wall of the auxiliary fixing bracket 11, a second nut 13 is arranged on the left side of the outer side wall of the second threaded column 12, a connecting tube 18 is arranged at the center position of the outer side wall of the second threaded column 12, a first blade 15 and a second blade 16 are respectively installed on both sides of the connecting tube 18, and a wire rope 19 is installed on the inner side wall of the first blade 15.
