[0002] During the production and maintenance of high-voltage switchgear, a large number of gas cylinders are usually transported. Because full gas cylinders are too heavy, such as a 45L SF6 liquefied gas cylinder which can weigh up to 100 kg, the handling of the cylinders is extremely inconvenient and dangerous. The lifting and lowering of the cylinders during the loading and unloading process has become a major problem in cylinder transportation.

[0003] Currently, there is no relevant technology to solve the above problems and defects. Therefore, a cylinder lifting device is needed to assist in the transfer of cylinders on and off vehicles.

[0026] like Figure 1 As shown, a cylinder lifting structure includes a power structure, a control structure, and a lifting execution structure.

[0027] The power structure provides power to the lifting and lowering actuator.

[0028] The control structure, together with the power structure, controls the lifting and lowering of the lifting actuator structure;

[0029] The lifting actuator lifts the cylinder fixing frame 6 under the combined action of the power structure and the control structure;

[0030] The power module uses a hydraulic cylinder and a hydraulic system to drive the hydraulic cylinder.

[0031] The lifting and lowering actuator includes a hydraulic cylinder 7 that raises and lowers the cylinder fixing frame 6. The hydraulic cylinder 7 includes a hydraulic cylinder and a piston rod that slides up and down along the hydraulic cylinder.

[0032] It also includes a guide structure, which includes a vertical guide rail for the lifting and lowering movement of the cylinder fixing frame 6 and a slider 4 that slides along the guide rail. The guide rail is vertically mounted on a fixed column 5, and the fixed column 5 is also fixedly connected to the hydraulic cylinder of the hydraulic cylinder 7.

[0033] The upper part of one side of the cylinder fixing bracket 6 is fixedly connected to the slider 4, and the bottom is fixedly connected to the bottom of the piston rod of the hydraulic cylinder.

[0034] The cylinder fixing rack 6 has one or more cylinder positions. Each cylinder position has an anti-tipping lock 6.5 or a strap on the upper middle part of the cylinder body. The fixing end of the anti-tipping lock 6.5 or strap is fixed to the cylinder fixing rack 6.

[0035] In this application, the power module adopts a hydraulic system, including a hydraulic pump 3 and a hydraulic oil tank, and also includes a control mechanism, including an oil circuit control module, an electrical circuit control module, and a hydraulic cylinder.

[0036] In one embodiment, such as Figure 1 The control structure includes an oil circuit control module and a circuit control module, which are housed in the electrical box.

[0037] When the power module uses a hydraulic system, the lifting actuator is driven by a hydraulic cylinder 7. In one embodiment, such as... Figure 1The lifting and lowering actuator includes a hydraulic cylinder 7 that raises and lowers the cylinder fixing frame 6. The hydraulic cylinder 7 includes a hydraulic cylinder and a piston rod that slides up and down along the hydraulic cylinder.

[0038] It also includes a guide structure, which includes a vertical guide rail for the lifting and lowering movement of the cylinder fixing frame 6 and a slider 4 that slides along the guide rail. The mounting carrier of the guide rail is also fixedly connected to the hydraulic cylinder of the vertically mounted hydraulic cylinder 7. The mounting carrier of the guide rail is fixed at the expected lifting and lowering position of the cylinder by a fixing bracket 10.

[0039] The mounting carrier for the guide rail can be a fixed post 5 or a fixed frame. In one embodiment, such as... Figure 1 The mounting carrier for the guide rail is a vertically erected fixed column 5, which is also fixedly connected to the hydraulic cylinder of the hydraulic cylinder 7; the fixed column 5 is fixed to the expected lifting position of the cylinder by a fixed bracket 10.

[0040] The fixed column 5 is fixedly connected to the hydraulic cylinder. In one embodiment, as follows: Figure 1 The hydraulic cylinder 7 is fixed inside the fixed column 5. The fixed column 5 has a hollow structure. The hydraulic cylinder and the inner wall of the fixed column 5 can be fixedly connected by a connecting block. A cover plate is fixedly installed at the top of the fixed column 5, and a base plate is fixedly installed at the bottom of the fixed column 5. The base plate has a hydraulic rod through hole, through which the hydraulic rod extends or retracts. The hydraulic cylinder can also be installed outside the fixed column 5. The hydraulic cylinder and the fixed column 5 can be fixedly connected, either directly or indirectly through a connecting plate, connecting block, etc. The fixed connection described above can be welded or screwed, etc.

[0041] The cylinder fixing bracket 6 has its upper part fixedly connected to the slide block 4 on one side, and its base on the same side fixedly connected to the bottom end of the piston rod. The fixed connection includes direct fixed connections as well as indirect fixed connections such as connecting plates and connecting rods. Figure 1 In the embodiment shown, the cylinder fixing frame 6 and the guide rail slider 4 are connected by a connecting plate. The slider 4 is fixed to the connecting plate, and the connecting plate is fixed to the cylinder fixing frame 6 by screws. The bottom end of the cylinder fixing frame 6 on the same side is also indirectly fixed to the bottom end of the piston rod. A transverse connecting plate is fixed to the bottom end of the cylinder fixing frame 6 on the same side as the guide rail slider 4. The lower end of the piston rod of the hydraulic cylinder 7 is fixed to the transverse connecting plate, thereby realizing the fixed connection between the bottom end of the cylinder fixing frame 6 and the bottom end of the piston rod.

[0042] The cylinder fixing rack 6 has one or more cylinder positions, and each cylinder position has an anti-tipping lock 6.5 or a strap on the upper middle part of the cylinder body.

[0043] In one embodiment, the cylinder holder 6 is provided with a single cylinder position, such as... Figure 1The cylinder holder 6 can also accommodate 2-3 cylinder positions, the specific number of which can be set according to the power of the hydraulic cylinder 7. For easy movement, the cylinders in the positions are erected vertically. To prevent the cylinders from tipping over, each cylinder position is equipped with an anti-tipping lock 6.5 or a strap on the upper middle part of the cylinder body. The fixed end of the anti-tipping lock 6.5 or strap is fixed to the cylinder holder 6. The contact surface between the anti-tipping lock 6.5 and the cylinder body is arc-shaped.

[0044] In one embodiment, such as Figure 1 The cylinder fixing bracket 6 is set vertically, and the cylinder inside the cylinder fixing bracket 6 is also set vertically to prevent the cylinder from tilting during movement.

[0045] The base 1 of the cylinder holder 6 has openings on at least two adjacent or opposite sides. In one embodiment, such as... Figure 1 To facilitate the movement of the gas cylinders, the vertical sides of the base 1 are open on three adjacent sides, and the column on the base 1 of the gas cylinder fixing bracket 6 is set on the side adjacent to the guide rail slider 4.

[0046] In one embodiment, such as Figure 2 This application describes a method for mounting and dismounting gas cylinders on a vehicle loading platform. Specifically, the mounting post 5 is fixed to the side of the vehicle loading platform. In its initial position, the base 1 of the gas cylinder mounting bracket 6 is flush with the surface of the loading platform or cargo box platform of the transport platform. This installation method facilitates the lifting of gas cylinders from the ground to the loading platform or the lowering of gas cylinders from the loading platform to the ground. The mounting method is not limited, such as... Figure 2 In this embodiment, the fixing column 5 is fixed to the side of the vehicle loading platform via a fixing bracket 10. The fixing bracket 10 is fixed to the loading platform or the cargo box platform, and the fixing bracket 10 is provided with several connecting rods 10.1 extending out from the side of the loading platform or the cargo box platform. The connecting rods 10.1 are fixedly connected to the fixing column 5 to achieve the goal of fixing the fixing column 5. The side of the vehicle loading platform can be preset according to the convenience of loading and unloading the gas cylinders. Of course, the fixing column 5 can also be fixed to the side of the vehicle loading platform in other ways, such as indirectly by fixing rods. The fixing method is not limited here. Figure 2 In the middle, the hydraulic cylinder inlet and outlet oil pipes 7.1 are connected to the hydraulic pump inlet and outlet oil pipes, which is a conventional technology.

[0047] like Figure 2 In the illustrated embodiment, a transport vehicle is provided that uses the cylinder lifting device described above.

[0048] Furthermore, controlling the extension or retraction of the hydraulic cylinder piston rod through a hydraulic system is a common technique, which will not be elaborated here.

[0049] Working Principle. In the initial position, the piston rod is fully retracted into the hydraulic cylinder, and the base of the cylinder holder 6 is flush with the upper surface of the transport platform. The piston rod inside the hydraulic cylinder 7 extends downwards, and its bottom end is fixed to the bottom end (base) of the cylinder holder 6. The upper part of the cylinder holder 6 is fixed to the slider 4 on the guide rail, thus driving the cylinder holder 6 to move downwards. When the piston rod descends to the lower limit, the cylinder holder 6 reaches its lowest position. By releasing the anti-tipping lock 6.5 or the straps, the cylinder can be moved in or out. The length of the piston rod can be appropriately designed based on the intended lifting height of the cylinder to achieve the desired purpose.

[0050] The piston rod inside the hydraulic cylinder 7 retracts upwards, and its bottom end is fixed to the bottom end (base) of the cylinder holder 6. The upper part of the cylinder holder 6 is fixed to the slider 4 on the guide rail, thus driving the cylinder holder 6 to move upwards. When the piston rod is fully retracted into the hydraulic cylinder, the cylinder holder 6 rises to its highest position. Within its travel range, an upper limit can also be designed. When the upper limit is reached, the base of the cylinder holder 6 is flush with the upper surface of the transport platform. At this time, the anti-tipping lock 6.5 or the strap can be released, and the cylinder can be moved in or out. Generally, the design can be such that the base of the cylinder holder 6 is connected to and flush with the upper surface of the desired position, facilitating the movement of the cylinder.

[0051] This embodiment does not impose any limitation on the shape, material, structure, etc. of this utility model. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this utility model shall fall within the protection scope of this utility model.
