Multifunctional SF6 inflating trolley

Abstract

The invention discloses a multifunctional SF6 inflating trolley. The multifunctional SF6 inflating trolley comprises a power transfer system for bearing and carrying air bottles and is characterized in that the power transfer system is a double-motor driven caterpillar band system for achieving 360-degree free rotation of a machine. The multifunctional SF6 inflating trolley further comprises a front flat ground walking wheel and a back flat ground walking wheel which are used for walking on the flat ground and are provided with a front flat ground walking wheel rising and falling mechanism and a back flat ground walking wheel rising and falling mechanism for controlling the walking wheels to perform rising and falling driving. The multifunctional SF6 inflating trolley is simple in structure, safe, reliable and labor-saving and improves carrying efficiency.

Description

technical field [0001] The invention relates to a multifunctional SF 6 inflatable car. Background technique [0002] In recent years, with the rapid development of my country's electric power industry and the improvement of technical equipment, SF 6 Electrical equipment has been heavily commissioned, SF 6 (Sulfur hexafluoride) gas is widely used in power systems due to its excellent insulation and arc extinguishing properties, and has almost become the only insulation and arc extinguishing medium used in medium-voltage, high-voltage and ultra-high voltage switches. At present, in my country's 63-750KV power system, SF 6 Gas Insulated Circuit Breakers and SF 6 The application of gas insulated substation (GIS) has been quite extensive, so for SF 6 Daily supervision of electrical equipment is increasingly important. Thanks to SF 6 There are a lot of equipment and after a long time of operation, there is often the possibility of air leakage, which requires regular air rep...

Problems solved by technology

Thanks to SF 6 There are a lot of equipment and after long-term operation, there is often the possibility of air leakage, which requires regular air replenishment

The following problems exist in the gas replenishment operation: 1) When replenishing gas, it is necessary to carry the cylinder up and down the stairs frequently, SF 6 The weight of the gas cylinder itself is 50KG, and the net weight of a bottle of fresh gas is 50KG. After filling the new gas, SF 6 The total weight of the gas cylinder is 100KG. In addition, the gas cylinder is cylindrical and there are no handles around it. Therefore, when moving the gas cylinder, multiple people are required to work at the same time, which is time-consuming and laborious. Moreover, due to the narrow stairs, the gas cylinder rolls during the transportation process. The unsafe factors of injuring people; 2) in the SF 6 Gas is backfilled to SF from cylinders 6 When the electrical switch is on, the pressure in the gas cylinder is greater than the pressure in the electrical switch, and the liquid SF in the gas cylinder 6 Will convert to gaseous SF at reduced pressure 6 output to the electrical switch, so there will be a physical phenomenon of heat absorption during the conversion process, and the SF 6 Gas cylinders often cause SF due to low cylinder temperature 6 The gas cannot be vaporized, and the refill efficiency is not ideal; especially in cold weather environments, due to the SF in the gas cylinder 6 The temperature will drop sharply, and frost will be formed around the gas cylinder, which prolongs the inflation time, and the risk of moisture in the external gas entering the equipment gas chamber at the inflation interface increases, and the temperature decreases, and the SF 6 From gaseous state to liquid state or even solid state, the gas supply can only be continued after the temperature rises, and the whole gas supply process takes a long time; 3) The amount of gas charged and replenished into the equipment is not easy to control; 4) Inflating and replenishing gas The nature of the gas cannot be monitored during operation

[0003] Existing Multifunctional SF 6 There are the following disadvantages in the air supply trolley: 1. The crawler power transmission system is driven by a single motor, which cannot realize the flexible steering when the machine climbs stairs. If the stairs are spiral, the function of climbing stairs cannot be realized; 2. Walking and turning on flat ground The wheels are free-swinging. This kind of structure is unreliable when climbing stairs. Occasionally, the swing will be inflexible and stuck and unable to climb the stairs. If the balance is not well grasped when walking on flat ground, the track will rub against the ground This will aggravate the wear of the track and bring inconvenience to moving on flat ground; 3. There is no real-time micro-water monitoring function, so the quality of the gas that enters cannot be detected; 4. The heater uses metal aluminum blocks to conduct heat, and the heat preservation effect is not good. Good and unsafe, the temperature drift is relatively large, and the displayed temperature is inaccurate
