The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0021] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0022] The utility model provides a power tower anti-falling device, such as Figure 1-3 As shown, the anti-fall device for the electric power tower includes: a rod body 1 installed on the ladder of the electric power tower, sliding grooves 16 are provided on both sides of the rod body 1, and a plurality of positioning grooves 14 are provided on the rod body 1; a U-shaped plate 2 is arranged on the rod body 1, and sliding holes are provided on both sides of the U-shaped plate 2; a plurality of limit blocks 3 are respectively slidably installed on the plurality of sliding holes, and the plurality of limit blocks 3 are respectively adapted to the plurality of sliding grooves 16; a hanging ring 4 welded on the U-shaped plate 2 for installing a safety rope 5; a plurality of moving mechanisms installed on the U-shaped plate 2 for moving the plurality of limit blocks 3; and a positioning mechanism assembled on the U-shaped plate 2 for fixing the U-shaped plate 2.

[0023] It should be noted that in the process of working on the power tower, in order to prevent the workers from falling from a height, safety ropes are usually used to ensure safety and prevent accidents from falling from a height. However, when the workers move up and down, they need to frequently remove and hang the hooks of the safety ropes. This operation process is not only cumbersome, but also prone to errors. If the workers fail to properly hang the hooks on the ladder or other safe positions of the tower due to negligence or other reasons, the safety rope may fail, thereby increasing the risk of falling from a height.

[0024] In this embodiment, before use, the rod body 1 of the device can be installed on the ladder of the power tower by welding or screwing. After installation, it can be used. When the staff uses the device to move up and down on the ladder of the power tower, the safety rope 5 is installed and fixed to the body of the staff. The hook at one end of the safety rope 5 needs to be hung on the hanging ring 4. Then the positioning mechanism is operated by hand to release the fixing of the U-shaped plate 2 by the positioning mechanism. After the release, the U-shaped plate 2 can move vertically on the rod body 1 so that the safety rope 5 can reach a suitable height. When the staff releases the positioning mechanism by hand, the positioning mechanism will automatically fix the U-shaped plate 2 on the rod body 1 to prevent the U-shaped plate 2 from moving. Through this operation mode, the staff does not need to remove and hang the hook of the safety rope 5 during the up and down movement, so that the hook of the safety rope 5 can always be hung on the hanging ring 4, which solves the problem that the staff is prone to fail to correctly hang the hook of the safety rope on the ladder of the tower or other safe positions due to negligence or other reasons during the operation on the power tower, which may cause the safety rope to fail, thereby increasing the risk of falling from a height.

[0025] In a further preferred embodiment of the utility model, the moving mechanism includes: a bolt 6 threadedly mounted on the U-shaped plate 2; a baffle 7 rotatably mounted on the bolt 6, and one side of the baffle 7 is fixedly connected to the limit block 3.

[0026] In this embodiment, the moving mechanism is used to move the limit block 3. When the U-shaped plate 2 needs to be removed from the rod body 1, the moving mechanism is required to move the limit block 3. During operation, the bolt 6 is rotated, the bolt 6 will drive the baffle 7 to move, and the baffle 7 will drive the limit block 3 to move. When the limit block 3 is moved out of the sliding groove 16, the removal of the U-shaped plate 2 is completed, and the operation is relatively simple and convenient.

[0027] In a further preferred embodiment of the utility model, the positioning mechanism includes: a shell 8 fixedly mounted on the U-shaped plate 2, two pull rods 9 being slidably mounted on the shell 8, and springs 10 being slidably sleeved on the two pull rods 9; a connecting plate 11 welded at one end of the two pull rods 9, a positioning block 12 being welded on the connecting plate 11, and the positioning block 12 is adapted to any one of the positioning grooves 14.

[0028] In this embodiment, the positioning mechanism is used to fix the U-shaped plate 2. When the U-shaped plate 2 needs to be moved, the pull rod 9 is used to pull the connecting plate 11 to move. The connecting plate 11 will drive the positioning block 12 to disengage from the positioning groove 14 and squeeze the spring 10. After the positioning block 12 disengages from the positioning groove 14, the U-shaped plate 2 can slide vertically on the rod body 1 at will. When the staff's hand is separated from the pull rod 9, the spring 10 will push the connecting plate 11 to move, and the connecting plate 11 will push the positioning block 12 to insert into the corresponding positioning groove 14, so that the U-shaped plate 2 can be quickly fixed on the rod body 1, which is more convenient to use.

[0029] In a further preferred embodiment of the present invention, a same handle 13 is fixedly mounted on one end of the two pull rods 9 , and the handle 13 and the two pull rods 9 are made of stainless steel.

[0030] In this embodiment, through the handle 13, the staff can easily operate the two pull rods 9 at the same time to make them move synchronously, thereby achieving precise control of the positioning block 12. The handle 13 and the pull rod 9 made of stainless steel have higher durability and reliability and will not rust.

[0031] In a further preferred embodiment of the present invention, a soft pad for reducing hardness is fixedly installed on the inner wall of the handle 13, and the soft pad is made of silicone material.

[0032] In this embodiment, a silicone cushion is fixedly installed on the inner wall of the handle 13 to improve the comfort of using the handle 13. The silicone material has good softness and elasticity, and can effectively relieve the pressure and discomfort caused by long-term operation or gripping of the handle 13.

[0033] In a further preferred embodiment of the present invention, a plurality of fixing plates 15 are welded to the rod body 1, and a plurality of fixing plates 15 are provided with a plurality of mounting holes for mounting screws.

[0034] In this embodiment, multiple mounting holes can facilitate relevant personnel to fix the device to the ladder of the power tower using screws.

[0035] In a further preferred embodiment of the present invention, a knob is fixedly mounted on one end of each of the plurality of bolts 6 , and a plurality of anti-slip sheets are fixedly mounted on each of the plurality of knobs, and the plurality of anti-slip sheets are all made of rubber.

[0036] In this embodiment, the knob can facilitate the staff to turn the bolt 6 by hand, and by installing a rubber anti-skid sheet on the knob, the staff's hands are not likely to slip when rotating the knob, and the knob has good anti-skid properties.

[0037] In a further preferred embodiment of the present invention, a plurality of grooves are formed on the plurality of limit blocks 3 , and balls are disposed on the inner walls of the plurality of grooves, and the plurality of balls are in contact with the plurality of sliding grooves 16 respectively.

[0038] In this embodiment, by providing the groove and the ball on the limit block 3, the contact effect and sliding performance between the limit block 3 and the sliding groove 16 are effectively improved. The rolling friction of the ball makes the limit block 3 move more smoothly in the sliding groove 16, reducing the jamming and wear caused by friction resistance.

[0039] To sum up, compared with the related art, the present invention can facilitate the staff to remove the U-shaped plate 2 from the rod body 1 through the use of a moving mechanism. The operation is relatively simple and convenient, and it is convenient for the staff to perform maintenance work on the U-shaped plate 2. The U-shaped plate 2 can be quickly fixed to the rod body 1 through the positioning mechanism, and the fixation of the U-shaped plate 2 can also be quickly released. After the fixation of the U-shaped plate 2 is released, the U-shaped plate 2 can slide on the rod body 1 at will, so that the safety rope 5 can reach a suitable height. Through this operation method, the staff does not need to remove and hang the hook of the safety rope 5 during the up and down movement, so that the hook of the safety rope 5 can always be hung on the hanging ring 4, which solves the problem that the staff currently fails to correctly hang the hook of the safety rope on the ladder or other safe position of the tower due to negligence or other reasons during their work on the power tower, which may cause the safety rope to fail, thereby increasing the risk of falling from a height.
