Description

Technical Field

[0001] This utility model relates to an insulated crank arm for an insulated aerial work platform, belonging to the field of aerial work platforms. Background Technology

[0002] Insulated aerial work platforms typically use a standard crank arm connection between the insulated platform and the uprights. While simple and reliable, this structure lacks insulation properties. Figure 1 , 2 As shown. For the cantilever arm to be used on an insulated aerial work platform, it needs to have a certain level of insulation. Currently, insulation is achieved by covering it with an insulating shell. However, the insulating shell is prone to aging or damage over time, posing a significant risk of electric shock to personnel working on the insulated platform, resulting in low insulation safety. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned deficiencies in the existing technology and to provide an insulated crank arm for an insulated aerial work platform with a reasonable structural design.

[0004] The technical solution adopted by this utility model to solve the above problems is: an insulated crank arm of an insulated aerial work platform, one end of which is connected to an insulated platform, and the other end of which is connected to a boom head. The boom head is mounted on the working arm. Its structural features are: the insulated crank arm includes an insulated crank arm head end, an insulated crank arm section, and an insulated crank arm tail end. The insulated crank arm head end and the insulated crank arm tail end are respectively connected to the two ends of the insulated crank arm section. The insulated platform is mounted on the insulated crank arm head end, and the insulated crank arm tail end is mounted on the boom head.

[0005] Furthermore, the head end of the insulated crank arm is connected to one end of the insulated section of the crank arm, and the other end of the insulated section of the crank arm is connected to the tail end of the insulated crank arm by bolts or adhesive.

[0006] Furthermore, the insulated section of the crank arm is made of insulating material.

[0007] Furthermore, the insulating platform is mounted on the head end of the insulating crank arm via a rotating bracket.

[0008] Furthermore, the tail end of the insulated crank arm is mounted on the arm head via a column.

[0009] Furthermore, the insulating platform is driven by a first motor and a first worm gear mechanism.

[0010] Furthermore, the insulated crank arm is driven by a second motor and a second worm gear mechanism.

[0011] Compared with the prior art, the present invention has the following advantages: the insulated crank arm of the insulated aerial work platform includes an insulated crank arm head end, an insulated crank arm section and an insulated crank arm tail end. The insulated crank arm section is made of insulating material. By connecting the insulated crank arm head end and the insulated crank arm tail end to the two ends of the insulated crank arm section respectively, the crank arm can have insulating properties.

[0012] Compared with existing crank arms, the insulated crank arm in this application has an additional layer of insulation safety protection. Even if the insulating shell covering the outside of the crank arm ages or is damaged, insulation can be achieved solely by the insulating section of the crank arm, which greatly improves insulation safety, reduces the risk of electric shock to workers on the insulated platform, and better meets the needs of live-line work.
