Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of insulating platform, and particularly relates to a height-adjustable movable insulating platform. BACKGROUND

[0002] The insulating platform used in coal mines is a device for preventing electrical equipment from leaking electricity and protecting miners' safety. Its main function is to isolate electrical equipment from the ground to prevent current from flowing into the ground through the human body or equipment shell, thereby avoiding electric shock accidents. According to the provisions of Article 434 of the 2022 edition of "Coal Mine Safety Regulations", "When operating the main circuit of high-voltage electrical equipment underground, the operator must wear insulating gloves and wear electrician's insulating boots or stand on an insulating platform", and the provisions of "Electric Power Safety Work Procedures" stipulate that "when installing and removing high-voltage fuses, safety glasses and insulating gloves should be worn, and insulating tongs should be used if necessary, and an insulating mat or an insulating platform should be stood on". At present, each high-voltage distribution field at the mine shaft, the ground 10kV and above distribution room is equipped with a fixed table type insulating platform. When using, it needs to be carried back and forth, which is very inconvenient. Moreover, the height of the switch cabinet in the ground 10kV distribution room is relatively high, and personnel standing on the ordinary insulating platform cannot meet the normal operation requirements. Although some operating sites are equipped with step type insulating platforms, manual carrying back and forth is required during operation, which is extremely inconvenient.

[0003] For example, Chinese utility model patent CN205656272U discloses a novel telescopic movable insulating rod test pen universal test table, which comprises a fixed support, the fixed support is a rectangular frame, a telescopic insulating rod is installed on each corner of the fixed support, a telescopic support is installed at the top end of the telescopic insulating rod, a movable insulating rod test pen fixing device is installed in the frames of the fixed support and the telescopic support in the same direction, the telescopic insulating rod and the fixed support are designed in an integrated manner, the telescopic support comprises a movable insulating rod test pen fixing device, a fixed insulating rod test pen fixing device and a test equipment terminal; the moving device comprises a universal wheel support, and the universal wheel is connected with the novel telescopic movable insulating rod test pen universal test table through the universal wheel support. The design of the universal wheel facilitates movement everywhere and can minimize the occupation of laboratory space by experimental equipment.

[0004] The above-mentioned device has simple structure and poor functionality. When assembling electrical equipment such as distribution rooms, it cannot be well matched with transport vehicles for loading and unloading, the labor intensity is large, and it has not met the needs of on-site use. Therefore, we need to improve it. UTILITY MODEL CONTENTS
