Self-lifting rotary insulation cage

Abstract

The invention discloses a self-lifting rotary insulation cage. The cage comprises an insulation rack frame (9), lifters (5), self-locking division-plate type hooks (1) and a cage body (7). Racks (10) are arranged on the two sides of the insulation rack frame respectively, and the lifters are spaced vertically and movably connected with the insulation rack frame. The lifters comprise shells (5a), pin shafts (16) and lifting gears (18), wherein the pin shafts (16) are arranged on the shells, and the lifting gears (18) are fixedly arranged on the pin shafts and meshed with the racks. A connecting gear disc (11) is arranged on one side of one lifter of the upper portion of the insulation rack frame, and supporting discs (12) are arranged on the side, opposite to the connecting gear disc, of the cage body. The connecting gear disc is movably connected with the supporting discs through a supporting shaft (15), and a rotary shaft (14) is arranged between the two supporting discs. A rotary gear (13) is arranged on the rotary shaft, and one end of each pin shaft and one end of the rotary shaft are connected with a lifting power device (17) and a rotary power device (8) respectively. The self-lifting rotary insulation cage is simple, compact, firm and reliable in structure and wide in working range, and working is convenient and safe.

Description

technical field [0001] The invention relates to an auxiliary device for live work, in particular to a portable self-elevating and rotatable insulating working bucket. Background technique [0002] At present, in the live operation process of the 10KV distribution network of the power system, insulation and isolation measures are often used, including the insulation isolation between the human body, metal tools and live lines or equipment, and the distance between the human body, metal tools, etc. and the grounding body or device. Insulation isolation between. For example, insulating platform devices are an effective insulation measure used to isolate the human body, metal tools and grounding bodies or devices, but it requires multiple people to install, and the staff can only work through the insulating operating rod. Personnel cannot use insulating gloves to directly contact the live body for work. Most of the insulating work platforms in the prior art have fixed working p...

Problems solved by technology

For example, insulating platform devices are an effective insulation measure used to isolate the human body, metal tools and grounding bodies or devices, but it requires multiple people to install, and the staff can only work through the insulating operating rod. Personnel cannot use insulating gloves to directly contact the live body for work. Most of the insulating work platforms in the prior art have fixed working positions, narrow working space, very inconvenient operation, high requirements for insulation auxiliary isolation measures, and high requirements for the technical level of personnel. Generally, the operators can only be technicians with many years of rich technical experience, and there are many shortcomings such as high potential safety risks. Therefore, in the prior art, the insulated bucket truck is used to solve the above problems, and the support arm is driven by the hydraulic system or the electrical system. The working bucket is lifted and lowered to complete the electrical work, and this kind of insulated bucket arm truck not only has a complex structure and high technical requirements for operators, but also when working in mountains, depressions or line obstacles, the insulated bucket arm truck cannot reach the site, thus limiting its use. The scope and adaptability are not strong, and if it is rainy and snowy, it is difficult to climb up the concrete pole with electric climbing feet. In addition, the fixed insulating platform devices in the prior art, such as hoops and other devices, often loosen due to their poor fixing performance on the pole. Dangerous, work safety is difficult to be guaranteed
