Description

Technical Field

[0001] The utility model relates to a protective auxiliary device for high-altitude operations, in particular to a hanging cage for high-altitude power line operations. Background Art

[0002] At present, in the process of power construction, the protection for high-altitude operations is relatively weak. It is often the case that only safety ropes are used as the only protection measure. During construction, workers sit directly on the high-altitude wires. In this case, the construction is relatively difficult and can easily cause damage to electrical equipment (insulators and wires). At the same time, due to the limited space, it poses a great challenge to the safety of workers working at heights. In order to facilitate construction and solve problems, each construction unit processes the hoist cage by themselves. The shapes are varied, and there are hidden dangers in safety performance to varying degrees. Safety risks are prone to be difficult to control. Summary of the Invention

[0020] In order to make the purpose, technical solution and advantages of the present invention more clear, the present invention is further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be noted that the embodiments of the present invention and the features therein can be combined with each other unless there is any conflict.

[0021] It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present invention.

[0022] Some embodiments of the present invention are described below with reference to the accompanying drawings.

[0023] Reference Figure 1-3 , a cage for high-altitude power line operations, including a base plate 1, the bottom of the base plate 1 is installed with a supporting bottom frame 2 composed of seamless square tubes, the top corners of the supporting bottom frame 2 are fixedly installed with vertically upward outer frame pillars 3, and a detachable protective frame 4 is installed between two adjacent outer frame pillars 3. The upper ends of the outer frame pillars 3 are provided with mounting holes 5, and a balancing connecting ring 6 for fixing the sling is installed on the mounting hole. During transportation, the outer frame pillars 3, protective frame 4, etc. are removed from the supporting bottom frame 2. The detachable installation method is adopted, which is convenient for transportation and carrying to adapt to various construction environments. The center of gravity is adjusted by the balancing connecting ring to ensure the stability of the staff in the cage, providing safety guarantees for high-altitude workers, meeting and improving engineering needs in a quick, convenient and safe manner, and greatly improving work efficiency and quality.

[0024] The lower end of the balancing connection ring 6 is provided with a clamping portion 7 , and the clamping portion 7 is clamped and fixed on the upper end of the outer frame support 3 .

[0025] The mounting hole 5 is composed of multiple circular holes, and two adjacent circular holes partially overlap to form a long row of hole structure. The clamping portion 7 is provided with a first fixing hole 8, and a first screw is passed through the first fixing hole 8, and the first screw passes through the center of one of the circular holes in the mounting hole 5.

[0026] In this embodiment, a maximum of two people can be accommodated for work. Since the weights of the two people are different, when the two people stand in the cage, they will lean toward the side with the heavier weight. The first fixing hole 8 on the clamping part 7 is aligned and fixed with the different circular holes on the mounting hole 5, thereby adjusting the position and length of the sling fixing point to make the cage in a balanced state, thereby ensuring the stability of the staff in the cage.

[0027] A second fixing hole 10 is provided below the mounting hole 5 corresponding to the center of each circular hole, and a third fixing hole 11 is provided on the clamping portion 7. The third fixing hole 11 coincides with one of the second fixing holes 10 and is penetrated and fixed with a second screw. The first screw cooperates with the second screw to fix the balancing connection ring 6, thereby further improving the installation strength of the balancing connection ring 6.

[0028] A limiting member 12 for limiting the swing of the clamping portion 7 is installed on the outer frame pillar 3. The limiting member 12 includes side walls 13 located on both sides. One end of the side wall 13 is connected by a connecting portion 14 (the connecting portion 14 is located on the outer side of the cage), and a symmetrical limiting portion 15 is provided on the inner side of the other end. After installation, the side wall 13 is clamped on the outer side of the clamping portion 7, and the side of the limiting portion 15 close to the connecting portion 14 abuts against the clamping portion 7, and the inner side of the connecting portion 14 abuts against the outer frame pillar 3.

[0029] When the cage is lifted, the lifting point is located in the center area of the cage, so the balancing connection ring 6 as a whole tends to shift toward the middle of the cage. When the first screw slips from the mounting hole 5, the balancing connection ring 6 will shift. Therefore, the present application adds the limiting member 12, and the connecting portion 14 abuts against the outer frame support 3, thereby preventing the limiting portion 15 from moving toward the middle of the cage. Since the side of the limiting portion 15 close to the connecting portion 14 abuts against the clamping portion 7, the tilting of the clamping portion 7 is limited, thereby effectively ensuring that the clamping portion 7 is always in a vertical state and will not shift, further improving the safety of high-altitude operations (if the clamping portion 7 suddenly shifts during the operation, the overall center of gravity of the cage will change, and the staff in the cage will easily lose their center of gravity and fall from the cage).

[0030] An adjusting nut 16 is provided on the connecting portion 14 , and the end of the adjusting nut 16 abuts against the outer frame pillar 3 . According to the installation position of the clamping portion 7 , the adjusting nut 16 is adjusted to ensure that the inner side of the limiting member 12 can abut and be fixed with the corresponding positions on the clamping portion 7 and the outer frame pillar 3 .

[0031] The side wall 13 is provided with a strip-shaped hole 9 for accommodating the first screw and the second screw.

[0032] A protective alloy plate is fixed on the protective frame 4, which is used by staff to carry out waist-mounted control on the one hand, and to prevent scattered materials and small tools from falling from high altitude on the other hand.

[0033] The protective frame 4 is provided with an upper fixed end, a middle fixed end and a lower fixed end. The lower fixed end and the lower end of the outer frame pillar 3 are fixed to the outside of the supporting bottom frame 2 at the same time. The middle fixed end is fixed to the outside of the middle part of the outer frame pillar 3, and the upper fixed end is fixed to the outside of the upper end of the outer frame pillar 3.

[0034] The bottom plate 1 is provided with anti-skid patterns to increase the friction between the soles of the workers' shoes and the bottom plate 1, prevent slipping, and further improve safety.

[0035] The protective frame 4 is provided with a detachable tool box for placing working tools, and each tool needs to be fixed to the tool box or the cage by a safety rope to prevent the tool from falling from a height.

[0036] In this product, all non-detachable connections are fixed by welding, which is stronger and more stable than screw fixation. The entire cage is treated with an electroplating protective layer (such as hot-dip galvanizing) to improve corrosion resistance.

[0037] The product has a load capacity of 1200kg, an allowed load of 400kg, and a safety factor of 3K (3 times the load limit), meeting the safety requirements of high-altitude crimping operations.
