Description

Technical Field

[0001] The present invention relates to the field of safety protective gear, and in particular to a safety rope fixing device for aerial work. Background Art

[0002] In some high-altitude operations, such as the installation of air conditioners and anti-theft nets, two people are usually used in a group. During the installation, one worker needs to climb to the high-rise outdoors. Although the worker will be tied with a safety rope, due to the differences in the structures of each house, there is usually no firm safety rope binding point. Therefore, the common practice is to tie the safety rope to another worker. Moreover, the indoor workers are not specifically responsible for ensuring the safety of the outdoor workers. Sometimes they also need to cooperate with the outdoor workers, such as moving the air conditioner outdoor unit or handing over various tools. If the outdoor worker suddenly falls, the weight of the body plus inertia, the indoor worker will be caught off guard, or if he or she does not stand firmly during work, it will be difficult to pull the falling worker. When danger comes, the lives of both people are in danger. Therefore, there is a need for a device that is easy to carry and very strong to fix the safety rope, so that the lives of people who need to climb to the outdoors to work at high altitudes can be guaranteed.

[0003] For example, CN202010711146.2 proposes a portable safety rope fixing frame for high-altitude installation of an air-conditioning outdoor unit, comprising a main pole and two soft panels, two nodule rods symmetrically installed at both ends of the main pole, the nodule rod comprising a plurality of short rods, hinges commonly installed on the side walls between two adjacent short rods, a plywood installed on each of the soft panels, and the ends of the two nodule rods away from the main pole are rotatably mounted on the two plywood. This invention achieves fixed support by fixing the nodule rod against the window wall with reverse vertical force and driving the clamping rod against the wall in reverse by a toothed disc, which facilitates the fixing of the safety rope, increases safety, and does not damage interior decoration. By bending the nodule rod and driving the clamping rod to be retracted by a toothed disc, the occupied space is reduced and its portability is increased. However, the safety rope fixing frame needs to be fixed above and below the window, which makes it too large and reduces its portability.

[0004] The present invention can be fixed outside a door or at a corner of a window, and the safety rope can be fixed, thereby protecting high-rise outdoor workers. Summary of the Invention

[0045] In a specific embodiment: when in use, the first fixing block 7 and the second fixing block 11 are adjusted respectively by the first adjusting bolt 8 and the third adjusting bolt 12, so that the first fixing block 7 and the second fixing block 11 can slide on the fixing rod 1, and the distance between the first fixing block 7 and the second fixing block 11 is adjusted to adapt to the width of the door frame, and the second anti-slip block 13 on the side of the second fixing block 11 is made to press against one side of the door frame, and then the first anti-slip block 10 is adjusted by the second adjusting bolt 9, so that the first anti-slip block 10 presses against the other side of the door frame, so that the fixing rod 1 is fixed to the door frame through the limit device.

[0046] like Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, the aerial work safety rope fixing device includes an anti-rollover device, which includes: a third fixing block 14, the third fixing block 14 is arranged at the middle of the fixing rod 1 through a fourth adjusting bolt 15; a mounting block 16, the mounting block 16 is rotatably arranged above the third fixing block 14 through a fifth adjusting bolt 17; a first telescopic rod 18, the first telescopic rod 18 is movably mounted on the mounting block 16, one end of the first telescopic rod 18 is provided with a sixth adjusting bolt 19, the sixth adjusting bolt 19 is rotatably provided with a third anti-sliding block 20, and the other end of the first telescopic rod 18 is provided with a sixth adjusting bolt 19.

The first telescopic rod 18 is higher than the upper surface of the first fixed block 7, the second fixed block 11 and the fourth fixed block 26, so that the first telescopic rod 18 can be rotated above the fixed rod 1 when stored, thereby reducing the storage volume.

[0047] In a specific embodiment, when in use, the fifth adjusting bolt 17 is adjusted to allow the mounting block 16 to rotate on the third fixed block 14 , and the first telescopic rod 18 on the mounting block 16 to move, thereby adjusting the angle between the first telescopic rod 18 and the fixed rod 1 .

[0048] When installed on the door frame, the fixing rod 1 is horizontally fixed to the door frame through the limit device, and then the first telescopic rod 18 is adjusted to be perpendicular to the fixing rod 1 by adjusting the fifth adjusting bolt 17, and then the clamping ring 21 is adjusted by the seventh adjusting bolt 22, and then the extended length of the second telescopic rod 23 and the third telescopic rod 24 is adjusted, so that the fourth anti-sliding block 25 is against the upper or lower side of the door frame, and then the third anti-sliding block 20 is against the other side by adjusting the sixth adjusting bolt 19, so that the fixing device is fixed to the door frame in a "cross" shape to prevent the fixing device from rotating due to uneven force on the safety rope A.

[0049] When installed on the windowsill, the fixing rod 1 is clamped at a corner of the windowsill through the first fixing block 7 and the second fixing block 11 provided with chamfered surfaces included in the limiting device, and then the first telescopic rod 18 is adjusted horizontally or vertically on the windowsill by adjusting the fifth adjusting bolt 17 to prevent the limiting device from sliding.

[0050] like Figure 12 As shown, the aerial work safety rope fixing device includes an adjusting device, which includes: a fourth fixed block 26, which is arranged above the fixed rod 1 through an eighth adjusting bolt 27, located on both sides of the third fixed block 14, and located between the first fixed block 7 and the second fixed block 11; a first clamping block 28, one end of the first clamping block 28 is rotatably arranged on the fourth fixed block 26, and the other end of the first clamping block 28 is provided with a limiting groove; a ninth adjusting bolt 29, the lower end of the ninth adjusting bolt 29 is rotatably arranged on the fourth fixed block 26, and the upper end of the ninth adjusting bolt 29 is slidably arranged in the limiting groove on the first clamping block 28, and the opposite surfaces of the fourth fixed block 26 and the first clamping block 28 are provided with corresponding arc-shaped notches, and the inner surface of the arc-shaped notch is provided with an anti-slip groove 34.

[0051] In a specific embodiment, the safety rope A is fixed by the fourth fixing block 26 and the first clamping block 28 on both sides, and the tightness and length of the safety rope A are adjusted by the ninth adjusting bolt 29 .

[0052] like Figure 14 As shown, the aerial work safety rope fixing device includes a deceleration device, which includes: a first mounting plate 30 and a second mounting plate 31, which are respectively arranged on the upper and lower sides of the fixing rod 1 by screws; a first pulley 32, which is rotatably arranged between the first mounting plate 30 and the second mounting plate 31; a second pulley 33, which is movably arranged between the first mounting plate 30 and the second mounting plate 31, and is located on both sides of the first pulley 32, and a slide groove 34 is opened on the first mounting plate 30 and the second mounting plate 31, and the second pulley 33 is installed in the slide groove 34; a guide column 35, which is rotatably arranged between the first mounting plate 30 and the second mounting plate 31, and is located on the outside of the second pulley 33.

[0053] In specific embodiments: the safety rope A is fixed on the adjusting device, the middle part is wound on the first pulley 32, the second pulley 33 and the guide column 35, and the guide column 35 leaves a margin between the two sides of the adjusting device, which is used to adjust the length of the safety rope A. When one end of the adjusting device is accidentally touched or fails, the fixed end of the safety rope A on the worker will be pulled down due to the weight of the worker, so that the safety rope A is tightened, thereby moving the second pulley 33 on both sides of the first pulley 32 along the sliding groove 34 to the first pulley 32, thereby reducing the distance between the first pulley 32 and the second pulley 33, so that the safety rope A wound between the first pulley 32 and the second pulley 33 is clamped, and the clamping force increases with the increase of the downward pulling force of the safety rope A, thereby slowing down the worker's falling, reducing the feeling of falling, preventing the worker from being pulled, and also reducing the instantaneous pulling force on the other end of the adjusting device, providing another guarantee for the safety of the worker.

[0054] The lower end of the first fixed block 7, the second fixed block 11, the third fixed block 14 and the fourth fixed block 26 is provided with a slot matching the shape of the fixed rod 1, which is used to adjust the tightness.

[0055] Working principle:

[0056] When installed on the door frame:

[0057] The fixed rod 1 is transversely placed outside the door frame, so that the anti-skid sleeve 2 tightly abuts the outer side of the door frame. When the connecting rod 3 needs to be installed, one end of the connecting rod 3 matching the inner diameter of the fixed rod 1 is inserted into the fixed rod 1. When inserted, the clamping block 4 is pushed into the compression spring 5. After being inserted into place, the clamping block 4 is reset by the spring 5 and clamped into the clamping groove 6 of the connecting rod 3. Then, the anti-skid sleeve 2 is slid to move the anti-skid sleeve 2 to the inserted connecting rod 3.

[0058] Then, the first adjusting screw 8 and the third adjusting screw 12 are used to adjust the first fixed block 7 and the second fixed block 11 respectively, so that the first fixed block 7 and the second fixed block 11 can slide on the fixed rod 1, and the distance between the first fixed block 7 and the second fixed block 11 is adjusted to adapt to the width of the door frame, and the second anti-skid block 13 on the side of the second fixed block 11 abuts against one side of the door frame. Then, the first anti-skid block 10 is adjusted by the second adjusting screw 9, so that the first anti-skid block 10 abuts against the other side of the door frame, thereby fixing the fixed rod 1 on the door frame by the limiting device.

[0059] When installed on the window sill:

[0060] The fixed rod 1 is clamped in one corner of the window sill through the chamfered inclined surface of the first fixed block 7 and the second fixed block 11 included in the limiting device, and then the first telescopic rod 18 is transversely or vertically placed on the window sill through the adjustment of the fifth adjusting screw 17 to prevent the limiting device from sliding.
