Description
Technical field
The utility model belongs to the ladder that a kind of people are used to ascend a height, specifically a kind of maintenance ladder that is used for the special use of transmission line high-altitude.
Background technology
At present, carry out in the transmission line work high above the ground in the work such as the maintenance of circuit on the pylon and installation, the maintainer hangs safety rope, directly stepping on the composite insulation substring that collapses overhauls, be easy to cause the damage of composite insulation substring, dangerous, also be that operational procedure is not allowed simultaneously.Typically use a kind of general rope ladder, rope ladder is fixed on the pylon uses, this rope ladder hangs on the pylon high-altitude, will swing with the wind, often makes the maintainer can't finish maintenance and installment work, and easily causes the accident, and also can't guarantee safety in production.For this reason, in safety in production, be starved of a kind of in light weightly, be easy to carry, can guarantee the ladder of safe suitable transmission line work high above the ground.
Summary of the invention
The purpose of this utility model is exactly at the transmission line work high above the ground, provides a kind of in light weight, hangs fixing-stable, does not swing, and is easy to carry a kind of transmission line high-altitude maintenance ladder of work safety.
The technical solution of the utility model is:
A kind of transmission line high-altitude maintenance ladder is made up of vertical rod and cross support arm, it is characterized in that: be equipped with in last ladder termination partly and be used for suspension and be fixed on suspension arrangement on the transmission line pylon angle steel; Described suspension arrangement comprises the suspension plate of the termination that is hinged on the ladder part, is inserted into the bolt, wing nut and the faced washer that hang the band hook in the plate hole, and the head of described suspension plate also is with hook.
This ladder is that upper and lower two ladders are partly formed, and upper and lower two ladders part is connected by folding device; Described folding device comprises two joints, connecting plate, bearing pin, baffle ring and moving casings, described two joints are plug-in mounting and being fixed on the vertical rod head of upper and lower two ladders part respectively, and it is hinged by bearing pin and connecting plate, at a vertical rod external stability baffle ring of descending stair subdivision, suit moving casing in the vertical rod of last ladder part.
The utility model has the advantages that in light weightly, hang fixing-stable, do not swing, be easy to carry, work safety is particularly suitable for the transmission line work high above the ground and uses, and is a kind of special-purpose ladder of transmission line work high above the ground.

Embodiment
Describe specific embodiments of the present invention in detail below in conjunction with accompanying drawing.
Illustrated in figures 1 and 2, be the utility model transmission line high-altitude maintenance ladder.It comprises upper and lower two ladder parts of being made up of vertical rod 1 and cross support arm 2, is equipped with in the termination of last ladder part to be used for hanging and being fixed on suspension arrangement 3 on the transmission line pylon angle steel, and described upper and lower two ladders part is connected by folding device 4.
Fig. 3, Fig. 4 and shown in Figure 5 are the suspension arrangements of transmission line high-altitude maintenance ladder.Suspension arrangement is inserted into the bolt 302, the wing nut 303 that hang the band hook in the plate hole and is formed with faced washer 304 by the suspension plate 301 of the termination that is hinged on the ladder part; The head of described suspension plate also is with hook; The head of suspension plate be used to be hooked at transmission line pylon angle steel, and tighten, ladder is close to and is suspended on the transmission line pylon by wing nut and bolt with hook bolt.Suspension arrangement can rotate with suspension plate, can adapt to the suspension of the angle steel of diverse location and direction on the transmission line pylon and fixing like this.
Fig. 6 and shown in Figure 7 is the folding device of transmission line high-altitude maintenance ladder.Folding device comprises two joints 401, connecting plate 402, bearing pin 403, baffle ring 404 and moving casing 405, described two joints are plug-in mounting and being fixed on the vertical rod head of upper and lower two ladders part respectively, and it is hinged by bearing pin and connecting plate, at a vertical rod external stability baffle ring of descending stair subdivision, suit moving casing in the vertical rod of last ladder part.When transmission line high-altitude maintenance ladder used, upper and lower two ladder parts were stretching, moving casing are sleeved on the position of joint and connecting plate, and drop on the fixed stop ring of descending stair subdivision, and at this moment, upper and lower two ladders partly become one.As when carrying or carrying, the suit moving casing being pulled away from the position of joint and connecting plate, ladder can be folded up, as shown in Figure 8.
