Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of loading and unloading, and particularly relates to a gas cylinder loading and unloading and transporting device. BACKGROUND

[0002] The GIS device has high reliability, strong safety and small maintenance workload, and the maintenance interval of main components is not less than 20 years. The main arc extinguishing material SF6 gas has superior arc extinguishing ability, thermal characteristics and heat dissipation capacity. The SF6 gas has strong negative electricity, and the SF6 molecules can easily absorb free dispersed electrons in a physical electric field and form negative ions with large mass. This feature can effectively reduce the ionization collision in the gas, so it has superior arc extinguishing ability and is particularly suitable for high-voltage and large-current breaking.

[0003] At present, the GIS device plays an important role in high-voltage, super-high-voltage and ultra-high-voltage power transmission. In order to ensure the normal work of the GIS device, the working pressure of the SF6 gas in the device is usually kept at 0.5 MPa (gauge pressure). When the SF6 gas pressure is reduced to 0.4 MPa (gauge pressure), the device will alarm for low gas pressure, and the gas needs to be filled in time. However, the filling device for high-voltage electrical equipment in a substation usually has small capacity, and multiple gas cylinders are needed to fill the gas for the device with a large gas chamber. Since the weight of a single gas cylinder filled with gas is about 100 Kg, it is heavy. If multiple gas cylinders are carried to the gas filling device in the substation, multiple people are needed to carry them, and it is time-consuming and laborious to carry the gas cylinders by manpower, and the work efficiency is low.

Each gas cylinder is loaded into the gas cylinder fixing frame 2 of the vehicle body 1 by the same method as above, and the above operation is repeated.

[0057] The support frame 3 comprises a vertical plate 31, two first mounting seats 32, two second mounting seats 33, two first support rods 34 and two second support rods 35. The bottom of the vertical plate 31 is connected with the bottom inside the vehicle body 1; one side of each of the two first mounting seats 32 and the two second mounting seats 33 is fixedly connected with the outside of the vertical plate 31, and the two first mounting seats 32 are respectively located above the two second mounting seats 33; the two first support rods 34 are each a hollow structure, one end of each is hingedly connected with the two first mounting seats 32 respectively, and the telescopic ends of the electric telescopic rods of the two extension arms 45 are respectively inserted into the interiors of the two first support rods 34; one end of each of the two second support rods 35 is hingedly connected with the two second mounting seats 33 respectively, and the other end of each is connected with the middle part of the first support rod 34 through a pin shaft.

The insulating material is ceramic. The critical pressure of sulfur hexafluoride gas is 3.9 Mpa, the critical temperature is 45.6℃, and the gas is in a gas-liquid mixed state in a high-pressure gas cylinder at room temperature. The pressure and temperature of the saturated gas are closely related, but the latent heat of vaporization is high, and a large amount of heat is released during the gas release process, causing the gas temperature to drop rapidly, and the pressure in the cylinder to also decrease rapidly, resulting in slow or impossible inflation, especially long-term inflation, which can cause frost on the cylinder due to heat absorption, seriously affecting the inflation rate. Therefore, the heating pipe 5 can compensate for the heat released during inflation to ensure the temperature of the cylinder and meet the pressure requirement. At the same time, the heating pipe 5 can also directly heat the cylinder to ensure the temperature of the cylinder in a low-temperature environment and thus ensure the pressure of the gas in the cylinder.

When the GIS device needs to be inflated, the end of the main pipe is connected with the GIS device, and the high-pressure electromagnetic valve is opened, so that the GIS device can be inflated, and the working pressure of the gas in the GIS device is kept at 0.5 MPa. In addition, the GIS device is inflated by connecting multiple gas cylinders in parallel to the main pipe, without the need to replace the gas cylinder and switch the adapter multiple times, and SF6 gas leakage is prevented.

[0060] Working principle: when the device is used to load the gas cylinder into the vehicle body 1, the moving frame 41 is pushed to the gas cylinder, the motor 42 is connected with the battery, the motor 42 drives the screw rod 43 to rotate, the screw rod 43 drives the lifting plate 44 to move downward, when the lifting plate 44 moves to the lowermost end, the motor 42 is turned off, the lifting plate 44 is inserted into the gas cylinder below, the gas cylinder is placed on the lifting plate 44, the moving frame 41 is pushed to the front of the support frame 3, the motor 42 is started, the motor 42 is reversed, the lifting plate 44 drives the gas cylinder to move upward, when the electric telescopic rods of the two extension arms 45 are horizontally aligned with the two first support rods 34, the motor 42 is turned off, the electric telescopic rods are started, the telescopic ends of the electric telescopic rods are extended and inserted into the two first support rods 34, then the electric telescopic rods are turned off and the motor 42 is started, because the electric telescopic rods of the two extension arms 45 are inserted into the two first support rods 34, the positions of the two extension arms 45 and the lifting plate 44 are unchanged, therefore, the motor 42 and the moving frame 41 move upward relative to the lifting plate 44, when the bottom of the first universal wheel 411 of the moving frame 41 is flush with the bottom of the inside of the vehicle body 1, the motor 42 is turned off, the moving frame 41 is pushed into the inside of the vehicle body 1, then the electric telescopic rods are adjusted, the electric telescopic rods are shortened and withdrawn from the first support rods 34, the moving frame 41 is pushed to the gas cylinder fixing frame 2, and the gas cylinder is fixed on the gas cylinder fixing frame 2. Specifically, each gas cylinder is connected with a gas cylinder fixing frame 2 through multiple half-hoops. The above steps are used to load multiple gas cylinders into the gas cylinder fixing frames 2 of the vehicle body 1 and fix them. When the GIS device needs to be inflated, the vehicle body 1 is moved to the GIS device, the end of the main pipe is connected with the GIS device, and the high-pressure electromagnetic valve is opened, so that the GIS device can be inflated, and the working pressure of the gas in the GIS device is kept at 0.5 MPa.

[0061] As known from the above description, by the cooperation of the lifting structure 4 and the support frame 3, only a small number of workers or one worker is needed to automatically lift the gas cylinder and the lifting structure 4 loaded with the gas cylinder into the vehicle body 1 at the same time, multiple gas cylinders are easily loaded into the vehicle body 1 and transported to the GIS device for inflation, the loading and transporting process is simple and convenient, and the working efficiency is high.
