Description

Technical Field

[0001] This utility model relates to the field of cylinder conveying technology, and in particular to a mobile cylinder lifting and inverting device. Background Technology

[0002] In our work, we need to remove liquid products from 40L gas cylinders. The conventional method involves manual extraction, with two people working together to tilt the cylinder and collect the sample. One person lifts the front of the cylinder to determine the correct height and control the sample volume, while the other lifts the rear to control the flow rate of the liquid sample. Because the cylinders are large and heavy (>50kg), this method requires a high degree of coordination and physical strength from both parties, making it difficult to accurately control the sample volume. Furthermore, some of the products contained in these cylinders possess extremely high oxidizing and reactive properties, posing significant safety hazards to this sampling method.

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0038] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0039] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0040] The work requires removing liquid products from 40L steel cylinders. The conventional method is to do this manually, with two people working together to pour the cylinders for sampling. This process requires a high degree of coordination and physical strength from both parties and poses significant safety hazards.

[0041] In view of this, the present invention provides a mobile gas cylinder lifting and inverting device, including a frame 100, a clamping assembly 200, a rotating assembly 300, and a lifting assembly 400; the clamping assembly 200 is rotatably mounted on the lifting assembly 400 for clamping the gas cylinder; the rotating assembly 300 is mounted on the lifting assembly 400 and connected to the clamping assembly 200 for driving the clamping assembly 200 to rotate around a horizontal axis; the lifting assembly 400 is mounted on the frame 100 for driving the clamping assembly 200 and the rotating assembly 300 to move in the vertical direction.

[0042] The mobile cylinder lifting and inverting device provided by this utility model, through the cooperation of the clamping component 200, the rotating component 300, and the lifting component 400, raises the cylinder to a suitable position using the lifting component 400, and then the rotating component 300 rotates the cylinder so that the cylinder opening faces downwards to complete the inversion and sampling. With the use of the above-mentioned mechanical mechanism, only one person is needed to complete the operation, resulting in low labor intensity, simple operation, and improved safety as the operator can stay away from the cylinder.

[0043] The following combination Figures 1-5 The structure and shape of the mobile cylinder lifting and inverting device provided in this embodiment are described in detail below:

[0044] In an optional embodiment, the clamping assembly 200 includes a connecting rod 210, a rotating shaft 220, and a locking ring 230, such as... Figure 3 As shown, both the locking ring 230 and the rotating shaft 220 are connected to the connecting rod 210, with the axis of the rotating shaft 220 horizontally positioned. The locking ring 230 is fitted onto and holds the gas cylinder, allowing the cylinder to rotate around the rotating shaft 220. Specifically, the locking ring 230 can be configured as a clamp, a common structure which will not be described in detail here; alternatively, it can employ a two-half-ring structure, with one half-ring connected to the connecting rod 210, and the two half-rings detachably connected for easy locking of the gas cylinder. This detachable connection can be a bolted connection for convenient locking operations.

[0045] Furthermore, the clamping assembly 200 also includes a support tray 240 and a cylinder buckle 250; the support tray 240 and cylinder buckle 250 are connected to the connecting rod 210 and are respectively disposed at both ends of the cylinder. The support tray 240 is used to restrict the lower end of the cylinder, and the cylinder buckle 250 is used to restrict the upper end of the cylinder. The two cooperate with each other to prevent the cylinder from moving along its own axis, thereby cooperating with the locking ring 230 to reliably fix the cylinder. The cylinder buckle 250 is used to prevent the cylinder from slipping when inverted.

[0046] Specifically, the cylinder buckle 250 is detachably connected to the connecting rod 210 to facilitate the insertion of the cylinder. A threaded hole is provided on the connecting rod 210, and the cylinder buckle 250 is fixed to the connecting rod 210 with screws. The cylinder buckle 250 is configured as a cover plate with a through hole, such as... Figure 1 , Figure 2 As shown.

[0047] When clamping the gas cylinder, first place the gas cylinder on the support tray 240, then lock the locking ring 230, and finally install the gas cylinder buckle 250.

[0048] In this embodiment, the axis of the rotating shaft 220 intersects perpendicularly with the axis of the gas cylinder, thereby keeping the gas cylinder in balance and facilitating its rotation and maintenance of a stationary state. Furthermore, to facilitate the rotation of the gas cylinder and maintain its stability, the rotating shaft 220 is positioned at the midpoint of the gas cylinder's height direction.

[0049] In an optional embodiment, the rotating assembly 300 includes a reducer 310, a transmission rod 320, and a handwheel 330, such as... Figure 2 As shown; the reducer 310 is installed on the lifting assembly 400, the output end of the reducer 310 is connected to the clamping assembly 200, the input end of the reducer 310 is connected to the transmission rod 320, and the handwheel 330 is connected to the transmission rod 320.

[0050] Specifically, the reducer 310 can be a motor reducer 310, such as a worm gear reducer 310, a planetary gear reducer 310, a bevel gear reducer 310, etc. The output end of the reducer 310 is connected to the rotating shaft 220. In the structure of this embodiment, the input shaft and output shaft of the reducer 310 are perpendicular to each other, so that the operator can stay away from the gas cylinder.

[0051] In use, the handwheel 330 is turned to drive the transmission rod 320 to rotate, and then the torque is transmitted to the rotating shaft 220 through the reducer 310 to drive the cylinder to rotate.

[0052] Furthermore, the transmission rod 320 is rotatably mounted on the lifting assembly 400 to prevent the transmission rod 320 from forming a cantilever, facilitating the rotation of the handwheel 330. To reduce wear and frictional resistance, a bearing can be provided, which is mounted on the lifting assembly 400 and fitted onto the transmission rod 320.

[0053] In an optional embodiment, the lifting assembly 400 includes a lifting frame 410, a telescopic rod 420, a sprocket 430, and a chain 440; the clamping assembly 200 and the rotating assembly 300 are mounted on the lifting frame 410, the lifting frame 410 is movably mounted on the vehicle frame 100, and the telescopic rod 420 is mounted on the vehicle frame 100; the sprocket 430 is rotatably mounted on the extended end of the telescopic rod 420, one end of the chain 440 is connected to the vehicle frame 100, and the other end passes around the sprocket 430 and is connected to the lifting frame 410; the telescopic rod 420 extends and retracts to drive the sprocket 430 to rise and fall, and then drives the lifting frame 410 to rise and fall through the chain 440.

[0054] Specifically, the lifting assembly 400 also includes a seated bearing 450, which is mounted on the lifting frame 410, and a rotating shaft 220 is mounted on the seated bearing 450. The reducer 310 is mounted on the lifting frame 410, and the transmission rod 320 is rotatably mounted on the lifting frame 410.

[0055] In this embodiment, the lifting assembly 400 further includes an axle 460, and the sprocket 430 is rotatably mounted on the extended end of the telescopic rod 420 via the axle 460. Figure 2 As shown. Specifically, the axle 460 is connected to the extended end of the telescopic rod 420 and is set horizontally, and the sprocket 430 is rotatably mounted on the axle 460.

[0056] In this embodiment, the sprocket 430 and chain 440 form a movable pulley mechanism. To ensure stable operation, two sets of pulley mechanisms are provided, symmetrically arranged about the telescopic rod 420. Optionally, the sprocket 430 can be replaced with a pulley, and the chain 440 can be replaced with a wire rope.

[0057] In this embodiment, the frame 100 is provided with a vertically extending track groove 111; the lifting frame 410 is provided with track wheels 411, which engage with and roll along the track groove 111. The engagement of the track wheels 411 with the track groove 111 restricts the movement of the lifting frame 410 and reduces frictional resistance, ensuring stable vertical movement of the lifting frame 410. Similarly, to ensure stable operation, the frame 100 is provided with two track grooves 111, and two sets of track wheels 411 engage with each track groove 111, with each set containing at least two track wheels 411.

[0058] Specifically, the track groove 111 has a T-shaped cross-section and is used to limit the movement of the track wheel 411. The track groove 111 can be formed using C-shaped steel.

[0059] In this embodiment, the telescopic rod 420 is configured as a hydraulic cylinder. Optionally, the telescopic rod 420 can be configured as an electrically operated telescopic rod. The hydraulic cylinder can be a manual hydraulic cylinder to improve the flexibility of the equipment, which is not limited by the power source and can be moved to the desired position.

[0060] In an optional embodiment, the frame 100 includes a frame 110, wheels 120, and casters 130; the lifting assembly 400, wheels 120, and casters 130 are mounted on the frame 110. Specifically, two vehicles and two casters 130 are provided, and the wheels 120 are set as directional wheels, which can quickly and conveniently move and transport the gas cylinders, transporting them to suitable locations or for use in different sites. Furthermore, a telescopic rod 420 is mounted on the frame 110, and a track groove 111 is formed in the frame 110.

[0061] The mobile cylinder lifting and inverting device provided in this embodiment is manually driven using a manual hydraulic cylinder and handwheel 330, allowing one person to complete the tilting operation. The manual operation also improves flexibility and is not limited by power supply. The use of a reducer 310 enables precise tilt angle positioning with high accuracy and ease of operation, while also reducing the force required to turn the handwheel 330.

[0062] The mobile cylinder lifting and inverting device provided in this embodiment requires only one operator to complete the entire lifting and inverting process, greatly reducing labor intensity and costs. Simultaneously, remote, intermittent operation is achieved throughout the process, effectively ensuring operator safety. Furthermore, to further enhance safety, remote control can be achieved through electric drive; that is, the telescopic rod 420 is configured as an electric telescopic rod, and the handwheel 330 is replaced with a motor.

[0063] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
