Description

Technical Field

[0001] The utility model relates to the technical field of transportation and reloading, in particular to a multi-purpose SF6 gas cylinder operation trolley. Background Art

[0002] Sulfur hexafluoride (SF6) is a colorless, odorless gas with the chemical formula SF6. It is a colorless, odorless, non-toxic, and non-flammable stable gas at room temperature and pressure.

[0003] The transfer carts in the prior art are not convenient for getting on and off the vehicle for transportation. This problem leads to the fact that SF6 gas cylinders are mostly transported manually when they are taken out of the substation maintenance work site. Not only is the work efficiency low, but it is also dangerous and poses great risks to personnel. In addition, the applicable transportation environment of such carts is limited. Most of them are used in clean and flat indoor factories to transport SF6 gas cylinders. For substation maintenance work, some substations are located outdoors, and the outdoor road conditions are complicated. The existing transfer carts are difficult to adapt to various complex road conditions, making it inconvenient to transport SF6 gas cylinders to outdoor substations. Furthermore, the SF6 gas cylinders on the transfer cart can only be replenished upright during the refueling process, while the SF6 device specifications in the substation require inverted refueling. The existing transfer carts do not meet the specifications for refueling of power equipment, and thus a multi-purpose SF6 gas cylinder operation cart is urgently needed to solve the above problems.

[0020] See also Figure 1-2 , further illustrate the embodiments of the present utility model;

[0021] A multi-purpose SF6 gas cylinder operation trolley, comprising: a main frame 10, a ladder wheel 12, a gas cylinder sliding cage, a support frame 1 and casters 2, the ladder wheel 12 is installed at the bottom of the main frame 10, and the arrangement of the ladder wheel 12 facilitates the operation of the trolley on various complex road conditions. The gas cylinder sliding cage is rotatably connected to the main frame 10, and the gas cylinder sliding cage is used to place and fix the SF6 gas cylinder. The gas cylinder sliding cage can be rotated on the main frame 10, and the gas cylinder sliding cage can be rotated into the main frame 10 or rotated out of the main frame 10, so that the staff can carry the SF6 gas cylinder on and off the operation trolley; the support frame 1 is hinged to the gas cylinder sliding cage, and the main frame 10 and the support frame 1 are equivalent to the two supporting legs of the operation trolley, and there is always a support between the support frame 1 and the gas cylinder sliding cage. The angle can ensure that the operating trolley maintains balance during transportation; when the SF6 gas cylinder is transported on and off the vehicle and refilled with gas, the support frame 1 and the gas cylinder sliding cage are used to support the SF6 gas cylinder, and the main frame 10 is suspended and leans on the support frame 1; there is a pair of casters 2 and both are installed at the bottom of the support frame 1, and the casters 2 are always flush with the bottom of the ladder wheel 12, and brake pads are installed on the casters 2. When the main frame 10, the gas cylinder sliding cage, the support frame 1, the ladder wheel 12 and the casters 2 are used together, the staff can drive the operating trolley to move by directly pushing the main frame 10; a load-bearing plate 11 is welded to the lower end of the main frame 10 and is located next to the ladder wheel 12. The main frame 10 and the load-bearing plate 11 are used to bear the weight of the operating trolley and the SF6 gas cylinder, as well as the force-bearing main structure for pulling and flipping the gas cylinder sliding cage.

[0022] The gas cylinder sliding cage specifically includes a turning frame 4, a sliding frame 7 and a mobile base. The turning frame 4 is rotatably connected to the inner side of the main frame 10, so that the gas cylinder sliding cage can be turned over on the main frame 10, and there are slide grooves 6 on both inner sides of the turning frame 4. The two sides of the sliding frame 7 slide into the two slide grooves 6 respectively. The sliding frame 7 is used to place and fix the SF6 gas cylinder. The sliding frame 7 can slide in and out on the turning frame 4 through the two slide grooves 6, which is convenient for the installation or disassembly of the sliding frame 7. The mobile base is fixed to the bottom of the sliding frame 7; when the SF6 gas cylinder is transported on and off the vehicle and refilled with gas, the downward end of the support frame 1 and the mobile base is used to support the SF6 gas cylinder; in addition, the sliding frame 7 can also slide out directly from the turning frame 4, and the sliding frame 7 can be placed directly on the ground. At this time, the mobile base can not only support the sliding frame 7, but also drive the sliding frame 7 to move.

[0023] Several evenly distributed gas cylinder protection belt fixing rings 3 are installed on the sliding frame 7. The SF6 gas cylinder is placed on multiple gas cylinder protection belt fixing rings 3. The SF6 gas cylinder is tied to the gas cylinder protection belt fixing rings 3 by iron chains or ropes. The mobile base includes a base frame 8 and four pulleys 9. The base frame 8 is fixed to the bottom of several gas cylinder protection belt fixing rings 3, and the four pulleys 9 are respectively installed at the four corners of the bottom of the base frame 8.

[0024] A limiting plate 13 is welded to one side of the sliding frame 7 close to the turning frame 4 to prevent the SF6 gas cylinder from sliding off the sliding frame 7.

[0025] Limiting pieces 5 are integrally formed on both sides of the flip frame 4 close to the support frame 1 , and the limiting pieces 5 are hinged to the support frame 1 to ensure that the flip frame 4 and the support frame 1 can only rotate within a certain angle range.

[0026] This solution works as follows:

[0027] like Figure 1 As shown, when the SF6 gas cylinder needs to be loaded onto the vehicle, the operator holds the main frame 10 with one hand and pulls the sliding frame 7 with the other hand, so that the sliding frame 7 can be gradually slid out from the turning frame 4. Then, the sliding frame 7 is rotated downward, and the downward end of the support frame 1 and the movable base is used to support the operating trolley. At the same time, the main frame 10 and the ladder wheel 12 are flipped upward, and the ladder wheel 12 will lean against the support frame 1. Then, the brake pads on the caster 2 are braked to the caster 2, so that the operating trolley is positioned at that position, so that the operator can load the SF6 gas cylinder into the gas cylinder protection belt fixing ring 3 on the sliding frame 7, and use an iron chain or rope to tie the SF6 gas cylinder to the gas cylinder protection belt fixing ring 3;

[0028] After the vehicle is loaded, the brake pads on the casters 2 are opened and the sliding frame 7 is flipped. The sliding frame 7 will drive the flipping frame 4 to flip together, that is, the gas cylinder sliding cage is flipped as a whole. Since the limit pieces 5 are hinged to the support frame 1, the flipping frame 4 and the support frame 1 can only rotate within a certain angle range, so the support frame 1 will swing to a certain extent through the casters 2. The main frame 10 gradually approaches the ground under the action of gravity. The gas cylinder sliding cage and the SF6 gas cylinder will flip to the inner side of the main frame 10 under the action of gravity. The load-bearing plate 11 will support the gas cylinder sliding cage. At this time, the SF6 gas cylinder is placed upright. When the climbing wheel 12 moves to the ground and the support frame 1 and the main frame 10 remain in a stable state, the staff can push the main frame 10 to make the operating trolley move.

[0029] If you encounter uneven road conditions such as potholes, steps, etc., use the caster 2 as a fulcrum, hold the main frame 10 and flip it upward, and the climbing wheel 12 will crawl along the ground to meet the needs of operating the trolley to operate SF6 gas cylinders on various complex road conditions.

[0030] If the SF6 gas cylinder on the operating trolley needs to be refilled or unloaded, the sliding frame 7 is pulled out from the flip frame 4, slid and flipped toward the ground according to the steps of loading the SF6 gas cylinder, so that the downward end of the support frame 1 and the movable base is used to support the SF6 gas cylinder. The specific operation steps are not repeated here. At this time, the SF6 gas cylinder is placed inverted. When filling SF6 gas, in order to ensure the purity and stability of the gas, the best placement method is to invert the SF6 gas cylinder, which solves the problem that the existing transfer trolley does not meet the gas replenishment specifications for power equipment.

[0031] If the SF6 gas cylinder on the running trolley needs to be unloaded, the chain or rope is loosened on the basis of the SF6 gas cylinder being inverted, and the SF6 gas cylinder on the fixing ring 3 is no longer positioned. Then the staff can take the SF6 gas cylinder out of the sliding rack 7.

[0032] Compared with the prior art, the advantages of this application are:

[0033] 1. The efficiency of SF6 gas cylinder loading and unloading is greatly improved. Compared with traditional manual loading and unloading, after using this trolley, the number of loading and unloading personnel is reduced from 3 to 1, and the loading and unloading time is reduced from an average of 5 minutes to 3 minutes.

[0034] 2. The transfer trolley's adaptability to the transfer environment has been improved. Compared with traditional trolleys that are mostly suitable for flat factory buildings, this transfer trolley can adapt to various complex road conditions, making it easier to be used in outdoor substations, and its applicable environment has been greatly improved;

[0035] 3. The refueling method of the SF6 gas cylinder on the transfer vehicle is more in line with the specifications for SF6 gas cylinder refueling. Compared with the traditional upright refueling method, the inverted refueling method no longer has the problem of moisture in the air and air entering the cylinder, which is more in line with the requirements for SF6 gas cylinder refueling.
