The existing ladder head of the hanging ladder is an iron hook, and is directly hung on a guide wire during operation without an anti-falling device, so that a worker cannot move an operation position after taking a position; the length of the existing hanging ladder is 3 meters per section, multiple sections are assembled for use during operation, the accumulated length is 3 meters, 6 meters, 9 meters and the like so as to adapt to the height of a live-line operation bus of a transformer substation, and a vehicle is required to adapt to the length of the hanging ladder during transportation; the existing hanging ladder is formed by connecting a hanging ladder main column through a punching bolt, and each section of hanging ladder is fixed and cannot rotate as a whole after being connected.
Disclosure of Invention
The utility model discloses a portable single-column insulation hanging ladder, which has the characteristics of light weight, safety, high efficiency, simple operation, convenient transportation and the like. The maintenance operation of the equipment can be realized without power failure. The top end of a hook of the improved hanging ladder head is provided with a pulley, and a movable sealing door is added on the hanging ladder hook to prevent falling off in the operation process, so that the problem that the operation position cannot be moved after a person is in place is solved; the length of the improved hanging ladder is 1.1 meter per section, the length is more flexible when a plurality of sections are assembled and used during operation, the hanging ladder can be operated and used according to the lengths of 1.1 meter, 2.2 meters, 3.3 meters and the like, and the hanging ladder not only can be more suitable for the height of a bus of a transformer substation, but also is more convenient for vehicle transportation and carrying; after improvement, the main column of the hanging ladder is connected with another main column of the hanging ladder through a connecting movable joint, and each section of the hanging ladder can rotate in the vertical direction after being connected, so that the hanging ladder has the characteristics of a hard hanging ladder and a soft ladder.
The technical scheme of the utility model as follows:
the utility model provides a ladder is hung in insulating of portable single-column, by the ladder head, hang ladder king-post, ladder props and constitutes, the ladder head is sealed the door by couple, pulley, connecting plate, activity and is constituteed, and two couple positive antisymmetric are fixed on the top of connecting plate, and couple upper end installation pulley, the activity is sealed the door and is connected at the lower extreme of pulley with the both ends of couple, and it has protection rope connecting hole, transmission coaster connecting hole to open on the connecting plate, hangs the ladder king-post and sets up the ladder and prop, hangs the ladder king-post and is connected with another string ladder king-post through the hookup movable joint.
The main column of the hanging ladder is 1.1 m in length, and the distance between the ladder supports is 0.4 m.
The insulating part of the main column of the hanging ladder is made of epoxy phenolic glass fiber.
The pulley is an aluminum alloy pulley.
The connecting movable joint is made of steel.
The ladder head is made of aluminum alloy.
The utility model has the advantages that: 1. the portable insulating hanging ladder has the characteristics of safety, high efficiency, simplicity in operation, convenience in transportation and the like, and can realize maintenance operation on equipment without power outage; 2. the main material of portable insulating string ladder is the aluminum alloy, satisfies live working tool light in weight, the high requirement of mechanical strength.
