Abstract
The invention relates to an anti-climbing device of a centipede ladder of a transmission tower. The anti-climbing device comprises an upper arm and a lower arm, wherein the upper arm and the lower arm are of corresponding semicircular structures and are hinged to a main shaft of the centipede ladder, and locking devices which are matched are arranged on the corresponding ends of the upper arm and the lower arm. The anti-climbing device has the advantages of simple structure, low cost and convenience in operation, and after the anti-climbing device is locked, an adult cannot continue to climb when climbing to the locking position, so that irrelevant people are effectively prevented from climbing so as not to cause personal and property losses.
Description
Technical field
The present invention relates to a kind of transmission line of electricity auxiliary equipment, particularly a kind of transmission tower centipede type ladder anti-climbing device.
Background technology
In city, transmission tower polygamy has centipede type ladder, and convenient for maintaining operating personnel is upper and lower.But the centipede type ladder be arranged on shaft tower brings easily simultaneously, is also easily utilized by lawless person, lawless person easily climbs by centipede type ladder and implements to destroy to power equipment to shaft tower; Except not sending out except molecule, ruck is also easily injured, and in recent years, the case number of plies of electrocution is poor, wherein, deliberately climbs up transmission tower and causes getting an electric shock and dead occupy larger proportion.Therefore, being necessary, under the prerequisite of the climbing not affecting operating personnel, to carry out suitable protection to transmission tower centipede type ladder, is that people can not climb easily.
Summary of the invention
For the deficiencies in the prior art, the invention provides a kind of transmission tower centipede type ladder anti-climbing device.
The technical solution used in the present invention is: a kind of transmission tower centipede type ladder anti-climbing device, comprise upper arm and underarm, described upper arm and underarm are corresponding semicircular structure, and be articulated with on centipede type ladder main shaft, described upper arm and underarm corresponding end arrange the locking device of coupling.
Described transmission tower centipede type ladder anti-climbing device, is characterized in that: the internal diameter of described upper arm and underarm is greater than shaft tower external diameter.
Described transmission tower centipede type ladder anti-climbing device, is characterized in that: also comprise padlock, described upper arm and underarm corresponding end all arrange through hole.
Described transmission tower centipede type ladder anti-climbing device, is characterized in that: also comprise special shaped screw bolt, and described upper arm ends arranges the through hole mated with described special shaped screw bolt head size, and described lower arm ends arranges the screwed hole mated with described special shaped screw bolt.
Structure of the present invention is simple, and cost is low, easy to operate, and after locking, general adult cannot continue upwards to upper lock position in climbing, effectively prevents irrelevant personage from climbing thus causing the person and property loss.

Detailed description of the invention
Embodiment one:
As shown in Figures 1 to 3, upper arm 1 is identical semicircular structure with underarm 2, and its both ends are respectively fixed end and link, wherein, fixed end is articulated with on centipede type ladder main shaft, link arranges through hole 3, and upper and lower arm lead to the hole site coupling, the internal diameter of described upper arm and underarm is greater than transmission tower external diameter.
In the latched condition, upper and lower arm as centipede type ladder front, as Fig. 7.Two-arm through-hole alignment, uses padlock 5 upper and lower two-arm to be fixed, shuts the route upwards climbed from centipede type ladder.When needs are opened, padlock 8 opened by the key that work about electric power librarian use is corresponding, upper and lower arm is rotated to centipede type ladder behind, because upper and lower arm internal diameter is greater than transmission tower internal diameter, two-arm can be walked around shaft tower and again fix with padlock, without the need to again locking by operating personnel, on the one hand device is thoroughly opened, be not affected by the external environment, handled easily personnel are upper and lower, operating personnel also can not be made to have extra burden simultaneously.
Embodiment two:
As shown in Figs. 4-6, upper arm 1 is identical semicircular structure with underarm 2, its both ends are respectively fixed end and link, wherein, upper arm 1 fixed end is articulated with on centipede type ladder main shaft, link arranges through hole 3, underarm 2 fixed end is articulated with on centipede type ladder main shaft, link arranges the screwed hole 4 corresponding with through hole 3, and the internal diameter of described upper arm and underarm is greater than transmission tower external diameter.
In the latched condition, upper and lower arm as centipede type ladder front, as Fig. 7.Through hole 3 is aimed at screwed hole 4, uses special shaped screw bolt 6 to fix upper and lower arm, shuts the route upwards climbed from centipede type ladder.Wherein, special shaped screw bolt 6 head size is mated with through hole 3, its external screw thread mates with screwed hole 4, and special shaped screw bolt head adopts five angle heads, special tool must be used just to open, after bolt is screwed into, its head embeds through hole 3, and said structure greatly reduces stolen risk.
When needs are opened, work about electric power librarian use special tool is back-outed special shaped screw bolt 6, upper and lower arm is rotated to centipede type ladder behind, because upper and lower arm internal diameter is greater than transmission tower internal diameter, two-arm can be walked around shaft tower and again fix with special shaped screw bolt, without the need to again locking by operating personnel, on the one hand device is thoroughly opened, be not affected by the external environment, handled easily personnel are upper and lower, operating personnel also can not be made to have extra burden simultaneously.
