Embodiment 1

[0013] like figure 1 As shown, this embodiment provides an insulating ladder with handrails, including four support rods 1 and a pedal 2 installed on the top of the support rods 1, and two 1-meter guardrails 3 are arranged on the pedals 2 .

[0014] The guardrail 3 prevents some personnel from standing within less than 1 meter from the top of the ladder when they do not work according to the requirements of the ladder, or even when standing on the top of the ladder, there is no guardrail 3 to grasp when the fear causes the legs to tremble. A fall incident has provided certain safety guarantees for electric power workers.

Embodiment 2

[0016] On the basis of Embodiment 1, the four support rods 1 provided in this embodiment are installed at the four corners of the bottom surface of the pedal 2 through joint bearings, and a plurality of cross bars 4 are fixedly installed between the left and right support rods 1 . Two foldable reinforcing rods 5 are respectively arranged between the two supporting rods 1 ; non-slip rubber sleeves 6 are arranged on the bottom of the pedal 2 , the cross bar 4 and the supporting rod 1 .

[0017] Four support rods 1 make the insulation ladder more stable, and both ends can be used, which improves the convenience of the insulation ladder. The joint bearing connects the pedal 2 and the folding reinforcing rod, making the insulation ladder easy to fold and store, and at the same time improving the insulation ladder. Stability, the setting of the anti-slip rubber sleeve 6 improves the safety of the ladder.

Embodiment 3

[0019] It is basically the same as the above-mentioned embodiment, the difference is that a door 7 is respectively arranged between two 1-meter guardrails 3 in this embodiment, one end of the door 7 is hinged with the guardrail 3, the other end of the door 7 is provided with a hook, and the guardrail 3 is provided with a hook. There are grommets corresponding to the hooks.

[0020] The setting of the door 7 improves the safety of the insulating ladder. The opening and closing of the door 7 is realized through the hook and the grommet, and at the same time, the inherent height of the insulating ladder is increased, which provides a certain degree of security for the electric workers.

Abstract

The invention provides an armrest-carrying insulating ladder which comprises four support bars and a pedal installed on the top of the support bars. Two 1-meter guardrails are arranged on the pedal. According to the armrest-carrying insulating ladder, intrinsic height of an insulating ladder is increased, and a certain safety guarantee is provided for electric power operators.

Description

technical field [0001] The invention relates to an insulating ladder with handrails. Background technique [0002] Insulation ladders are mainly used for high-altitude operations during the maintenance of power system equipment. The equipment to be overhauled, such as outdoor transformers and transformers, are located at a higher position on the ground. When the insulation ladder is in use, it is required not to stand within 1 meter from the top of the ladder. On the ladder, always keep a safe protection height of 1 meter, let alone climb over the highest support point on the top. However, due to various restrictions, people often stand within a range of less than 1 meter from the top of the ladder, or even stand on the top of the ladder. Falling accidents are prone to occur during work. People standing at high places and surrounded by empty spaces are prone to fear. Fear will cause legs to tremble. If there are no handrails nearby, fall incidents will occur. Adding handrail...
