Description

An anti-fall device on a transmission tower pole

technical field

The invention relates to the technical field of electric power maintenance safety protection, in particular to a fall prevention device on a power transmission tower.

Background technique

Maintenance of transmission towers requires operators to climb the towers, especially when repairing 22 kV high-voltage transmission towers, the operator climbs to a height of tens of meters, and preventing personal falls is the most important safety protection measure. Among the various existing anti-falling devices, the anti-sliding clamping mechanism is installed on the guide rail pulley, and the safety belt of the climber is connected to the pulley. In order to ensure the absolute safety of the person, this mechanism must It is necessary to check the clamping mechanism and use it after confirming that it is safe and correct. Therefore, the cost of safety protection is high, labor-intensive and time-consuming, and it is inconvenient to use.

Contents of the invention

The technical problem to be solved by the present invention is to provide an anti-fall device on the transmission tower pole, which is connected with the safety belt of the climber. During the upward climbing process, the safety belt hanging ring is always hung in the anti-fall slideway, which has the function of preventing operation The operator falls from a high altitude, ensuring safety and improving maintenance efficiency.

In order to solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an anti-fall device on a power transmission tower, including an anti-fall slideway and a safety belt ring; the anti-fall slideway includes a plurality of long A strip-shaped rectangular frame, the rectangular frame is fixedly connected upwards along the right side of the vertical leg of the transmission tower pole, and several one-way movable blocks are arranged in each rectangular frame; the safety belt hanging ring includes a side plate , a seat belt hanging shaft, a latch sleeve and a spring latch, the side plates have two and are symmetrically arranged, and the seat belt hanging shaft is connected between the lower ends of the two side plates, and the latch sleeve has two and are respectively It is fixed on the upper end of the inner side of the two side plates. The opening between the two pin sleeves is the passage for the seat belt hanging ring to enter the rectangular frame. The spring pin is installed between the two pin sleeves. With manual pull tab.

A further improvement to the present invention is: the one-way movable catch is a spring plate fixed in a rectangular frame, the right end of the spring plate is provided with a connected double-layer splint, and the double-layer splint and the rectangular frame The right side is fixedly connected, and the left end of the spring plate is inclined toward the upper left and extends toward the left side of the rectangular frame.

The beneficial effects produced by adopting the above-mentioned technical scheme are: the present invention can make the safety belt link of the operator hang inside the anti-fall slideway all the time, and the safety belt link can automatically slide over the spring plate to rise with the height change of the climber. When the operator falls, the spring plate can hang the safety belt loop to ensure the operator's personal safety, reduce labor intensity and improve maintenance efficiency.

Detailed ways

Embodiment 1: An anti-fall device on a transmission tower pole, including an anti-fall slideway and a safety belt hanging ring; the anti-fall slideway includes a plurality of elongated rectangular frames 2 in the up-down direction, and the rectangular frame 2. It is fixedly connected upwards along the right side of the vertical leg 1 of the transmission tower, and several one-way movable blocks are arranged in each rectangular frame 2; the safety belt hanging ring includes a side plate 4 and a safety belt hanging shaft 8 , the latch sleeve 3 and the spring latch 11, the side plate 4 has two and symmetrically arranged, and the seat belt hanging shaft 8 is connected between the lower ends of the two side plates 4, and the latch sleeve 3 has two parallel They are respectively fixed on the upper ends of the inner sides of the two side plates 4, and the opening 9 between the two latch sleeves 3 is a channel for the safety belt hanging ring to enter the rectangular frame 2, and the spring latch 11 is installed between the two latch sleeves 3, A manual pull ring 12 is provided at the outer end of the spring latch 11 . The one-way movable block is a spring plate 6 fixed in the rectangular frame 2, and the right end of the spring plate 6 is provided with a conjoined double-layer splint, and the double-layer splint is fixedly connected with the right side of the rectangular frame 2 , the left end of the spring plate 6 is inclined toward the upper left and extends toward the left side of the rectangular frame 2 .

How to use: (see Figure 1) The rectangular frame 2 is fixedly connected upwards along the upright leg 1 of the transmission tower rod with spikes, forming an anti-fall slideway on the upright leg 1 of the transmission tower rod. (See Figure 2) Each section of rectangular frame 2 can choose 80mm*80mm angle iron with a length of 2 meters. A spring plate 6 is riveted at a distance, and the other side of the angle iron is welded with the vertical leg 1 of the transmission tower rod. At the beginning of maintenance and construction, the operator first fastens the safety belt 5 on the body, and the safety belt 5 is connected to the safety belt hanging ring reliably. Climb up, hold the side plate 4 on the safety belt hanging loop with the right hand, put the thumb into the manual pull ring 12 and pull the spring latch 11, the safety belt hanging loop enters the rectangular frame 2 through the opening 9 between the latch sleeves 3, and then When the operator can cooperate with both hands to climb the transmission tower pole, the safety belt hanging ring is pulled by the operator to move upward, and the safety belt hanging ring automatically slides over the spring plate 6 and rises to the top of the first rectangular frame 2. At this time, The operator's left hand holds the vertical leg 1 of the transmission tower pole, and the thumb of the right hand extends into the manual pull ring 12 to pull the spring latch 11, and the safety belt hanging ring exits the first rectangular frame 2, and then enters the second upper rectangular frame through the opening 9. Box 2. (See Fig. 2) During the upward climbing process, the operator's safety belt loop is always hung inside the rectangular frame 2. Once the body falls, the spring plate 6 can hang the safety belt loop to ensure the operator's personal safety.
