Abstract
The utility model is a scalable holding pole ladder comprising a ladder body and a base. The ladder body consists of a main ladder and an auxiliary ladder, which keep closely connected; a pulley, a pull rope whose one end is connected with the auxiliary ladder and one pair of clevis sling hooks that limits the free downward slide of the auxiliary ladder are arranged on the top of the main ladder; and a fixed cover of the holding pole, an anti-skid pedal and safety parapets are arranged on the auxiliary ladder. The height of the ladder bodies can be arbitrarily adjusted through the pull rope, and the clevis sling positioning hooks of the ladder bodies can be used for positioning lifting, with reliable performance.
Description
Technical field
The utility model relates to the pole-climbing facility of electric power, Office of the Telecommunications Authority's use.
Background technology
In electric power, Office of the Telecommunications Authority, pole-climbing is a basic job content.Existing pole-climbing mode one is to use pole-climbing tools such as pin hook, and two are to use common long ladder, and its security performance is all lower, and operation is also inconvenient.
Summary of the invention
The utility model is exactly to aim at pole-climbing operation and the telescopic pole ladder that designs.This ladder is made of terraced body and base.The ladder body is made up of main ladder and secondary ladder, and two ladders are close to connection, is provided with the stay cord that a fixed pulley and an end are connected with secondary ladder on the main ladder, a pair of goat's horn location hook that also restricted secondary ladder freely glides.On the secondary ladder pole fixed cover and antiskid pedal and safety barrier are arranged.This extension ladder ladder status section is formed, and is generally two, three sections, but the height regulated at will, to adapt to job requirements.Ladder base of body and pole fixed cover can guarantee that ladder is connected as a single entity with institute pole-climbing body down all the time on one's body, highly more also can not rock, and last lower beam is fool proof, make things convenient for.Safety when antiskid pedal that ladder is held on one's body and safety barrier have more increased operation.The use of goat's horn location hook makes lift adjustment ladder height degree very reliable, convenient.
Description of drawings
Fig. 1 is the telescopic pole ladder of a utility model structural representation.
Fig. 2 is the goat's horn location hook structural representation on the ladder.
Among the figure, 1 base, 2 main ladders, 3 stay cords, 4 goat's horn location hooks, 5 fixed pulleys, 6 pole fixed covers, 7 secondary ladders, 8 antiskid pedals, 9 safety barriers, 10 goat's horns, 11 horizontal stiles, 12 downslide backplates, 13 balance staffs.
The specific embodiment
Embodiment of the present utility model as shown in Figure 1, this telescopic pole ladder is made of terraced body and base, the ladder body is made up of main ladder 2 and secondary ladder 7, pulley 5 and an end and secondary ladder 7 stay cords that are connected 3 are set in main terraced 2 upper ends, the also restricted secondary ladder 7 a pair of goat's horn location hooks 4 that freely glide have pole fixed cover 6 and antiskid pedal 8 and safety barrier 9 on the secondary ladder 7.
As shown in Figure 2, goat's horn location hook 4 is arranged on the balance staff 13 of main ladder 2, and when secondary ladder 7 was carried on stay cord 3, the goat's horn 10 of goat's horn location hook 4 can slip over the horizontal stile 11 of secondary ladder 7, secondary ladder 7 is moved on unhinderedly, and can be hooked on lock height on the horizontal stile 10 at any time.When secondary ladder 7 needs to descend, need only stay cord 3 slightly, downslide backplate 12 is placed on the horizontal stile 11 protect goat's horn 10, goat's horn location hook 4 can be crossed horizontal stile 11 secondary ladder is freely descended around balance staff 13 left side pendulum.Thereby realize the quick adjustment of terraced height degree.
Claims (2)
1, telescopic pole ladder, constitute by terraced body and base, it is characterized in that terraced body is made up of main ladder (2) and secondary ladder (7), two ladders are close to, and pulleys (5) and an end are set with the secondary terraced stay cord (3) that is connected and limit a pair of goat's horn location hook (4) that pair terraced (7) freely glides in main ladder (2) upper end.
