Technical Field

The invention relates to the technical field of transformer substation equipment maintenance, in particular to an aerial work anti-falling bracket.

Background

To present open-type transformer substation, when overhauing 110kV isolator or going up the framework operation, the buckle device is hung for being fixed in the single-pole formula on the isolator bottom channel-section steel to current safety belt, and its shortcoming one: the fixation is unreliable, and the bottom fixing device is loosened due to the back-and-forth shaking of the safety belt in the working process, so that the safety belt loses the protection effect; the second disadvantage is that: the 110kV outdoor isolating switch has larger interphase distance, and no pedal capable of being treaded is arranged under feet in the transfer process of the personnel operating point, so that the personnel operating safety is greatly improved. Therefore, a device which can ensure that operators can conveniently transfer operation points between phases under the condition of ensuring the safety of high-altitude operation of the operators is developed, and the overhauling efficiency of the 110kV outdoor isolating switch can be obviously improved.

The safety belt hanging and buckling rod (19) is made of an insulating material. The pedal (16) is made of an insulating material. The safety belt hanging buckle rod base (18) is round or square, and a through hole is formed in the middle. The middle of the safety belt hanging buckle ring support (24) is provided with a through hole.

The use method of the invention comprises the following steps: the device consists of a safety belt hanging and buckling rod, a pedal and a fixing device. The safety belt hanging buckle rod is made of epoxy resin materials, is light, high in strength and strong in insulating property, two fixing holes are formed in the top of the safety belt hanging buckle rod, the safety belt hanging buckle rod is fixedly connected with the safety belt hanging buckle ring support, a bolt mode is adopted, safety belt hanging buckle rings are arranged on two sides of the safety belt hanging buckle ring support respectively, two fixing holes are formed in the bottom of the safety belt hanging buckle rod, and the safety belt hanging buckle rod is fixedly connected with the safety belt hanging buckle rod base on the pedal and adopts the bolt mode. The pedal frame adopts stainless steel, reduces its weight, and inside adopts the epoxy material, and intensity is high, and insulating properties is strong, and its both ends are equipped with the connector of being connected with fixing device, are equipped with the slot hole on the connector, can adjust according to the channel-section steel span of difference, lean on the border position to be equipped with the square or circular safety belt string knot pole base that the pole was buckled to the safety belt string in the middle part of the pedal. The fixing device adopts the hinging of the adjustable connector and the vertical arm and the hinging of the vertical arm and the transverse arm, and finally adopts the matching of the adjustable transverse arm and the bottom edge of the channel steel, so that the fixing device and the channel steel are reliably fixed through the spiral fixing rod.

The invention has the beneficial effects that: by using the anti-falling support for aerial work, operators can safely have reliable hanging and buckling points when the 110kV outdoor isolating switch is overhauled, safety protection cannot be lost in the process of transferring the operating points, the operation safety risk of the operators can be greatly reduced by the aid of the pedals, the operators can conveniently transfer the aerial work points, and the overhauling efficiency is improved.
