Description

Technical Field

[0001] This utility model relates to the technical field of gas cylinder handling equipment, specifically to a double-cylinder handcart for transporting gas cylinders. Background Technology

[0002] Gas cylinders, as common pressure vessels, are widely used in various fields such as industrial production, medical treatment, and laboratory research. The convenience and safety of their transportation and movement are crucial. Currently, the transfer of gas cylinders typically relies on specialized gas cylinder trolleys to reduce the burden of manual handling and improve operational efficiency.

[0003] However, existing gas cylinder trolleys still have many limitations in practical use. First, traditional trolleys mostly use a single-cylinder design, transporting only one cylinder at a time. This is inefficient when multiple cylinders need to be moved simultaneously, increasing repetitive operations and time costs. Second, gas cylinders vary in length, while the support structure of existing trolleys is often fixed and cannot flexibly adapt to cylinders of different heights and sizes. This causes the cylinders to easily shake, tilt, or even slip during transport, posing safety hazards. In addition, some trolleys are unstable when not in use and require external support, further affecting ease of use. Utility Model Content

[0004] To overcome the problems of existing gas cylinder trolleys being unable to transport multiple gas cylinders simultaneously, being unable to adapt to gas cylinders of different heights, and being unstable when not in transport mode, this utility model provides a dual-cylinder trolley for gas cylinders. By setting up a dual-cylinder bracket and an axial multi-level support frame, and optimizing the bottom support structure, it achieves synchronous and stable transport of two gas cylinders, adaptability to gas cylinders of multiple sizes, and self-standing parking of the trolley.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a double-cylinder trolley for gas cylinders, including two spaced-apart frame rods. A bracket for supporting the bottom of the gas cylinder is fixedly installed at the lower end of one side of the frame rod. Multiple supports for lateral support of the gas cylinder body are spaced apart along the axial direction on the same side of the frame rod. The multiple supports can adapt to gas cylinders of different heights and sizes. A wheel for walking is provided at the lower end of the other side of the frame rod. The bracket includes a first straight rod part and a first bent part. The first straight rod part is fixedly installed between the two frame rods. The first bent part extends outward from both ends of the first straight rod part.

[0006] The aforementioned dual-cylinder trolley for gas cylinders has a second straight rod extending outward from the middle of the first straight rod section, and two cylinder positions for placing gas cylinders are formed between the second straight rod section and the first bends on both sides.

[0007] The aforementioned dual-cylinder trolley for gas cylinders has its lowest point at the free end of the first bend aligned with the lowest point of the wheel, enabling the trolley to stand stably when not in transport mode.

[0008] The aforementioned dual-cylinder trolley for gas cylinders includes a support frame comprising a third straight rod and a second bent part. The third straight rod is fixedly disposed between two support rods, and the second bent part extends outward from both ends of the third straight rod.

[0009] The aforementioned gas cylinder double-cylinder trolley has an obtuse angle between the second bent section and the third straight section.

[0010] The aforementioned gas cylinder trolley with two cylinder positions has the support frame and bracket arranged on the same side of the frame pole.

[0011] The aforementioned dual-cylinder trolley for gas cylinders has an obtuse angle between the cross-section of the bracket and the support rod.

[0012] The aforementioned gas cylinder uses a dual-cylinder trolley, and the free end of the support pole is bent to form a handle that is easy for the hand to grip.

[0013] The beneficial effects of this utility model are: 1. It enables simultaneous and stable transportation of two gas cylinders, significantly improving handling efficiency.

[0014] 2. Through its multi-stage support design, it can flexibly adapt to and stably support gas cylinders of different heights and sizes, making it highly versatile.

[0015] 3. The structural design ensures that the cart can stand stably when not in transport mode, improving safety and convenience.

[0016] 4. The optimized angle and grip structure make loading and unloading gas cylinders easier and more convenient. Attached Figure Description

[0023] This utility model provides a dual-cylinder trolley, which is mainly used to solve the problems of existing gas cylinder trolleys having a limited number of transportable cylinders, being unable to adapt to gas cylinders of different heights, and having poor standing stability.

[0024] like Figure 1-4 As shown, in a preferred embodiment of this utility model, the dual-cylinder trolley includes two spaced-apart support rods 1. A bracket 2 for supporting the bottom of the gas cylinders is fixedly arranged at the lower end of one side of each support rod 1. The bracket 2 consists of a first straight rod portion 21 and first bent portions 22 located at its two ends. The first straight rod portion 21 is fixedly connected between the two support rods 1, and the two first bent portions 22 extend outward from both ends of the first straight rod portion 21, forming a right-angled arrangement with the first straight rod portion 21, thereby constituting a stable bottom support profile.

[0025] To further optimize the structure, a second straight rod 23 extends outward from the middle of the first straight rod 21, and this second straight rod 23 is flush with the first bent portions 22 on both sides. In this way, two independent cylinder placement positions are formed between the second straight rod 23 and the first bent portions 22 on both sides, so that the trolley can stably support two cylinders at the same time.

[0026] Preferably, the lowest point of the free end of the first bend 22 is flush with the lowest point of the walking wheel located at the lower end of the other side of the frame 1. This design allows the trolley to be supported on the ground by the first bend 22 of the bracket 2 and the wheel when not in transport mode, forming a stable standing posture without needing to lean on other objects.

[0027] On the same side of the support rod 1, i.e., the side where the bracket 2 is provided, multiple supports 3 are also arranged at intervals along the axial direction of the support rod 1 to provide lateral support for the gas cylinder body. The arrangement of multiple supports 3 enables it to provide effective support for gas cylinders of different heights and sizes, thereby adapting to various specifications of gas cylinders. Each support 3 consists of a third straight rod portion 31 and second bent portions 32 located at both ends thereon. The third straight rod portion 31 is fixedly connected between two support rods 1, and the two second bent portions 32 extend outward from both ends of the third straight rod portion 31 and form an obtuse angle with the third straight rod portion 31. This upward-opening structure can better enclose and limit the gas cylinder body.

[0028] Regarding the angular relationship, the included angle between the cross-section of the bracket 2 and the support rod 1 is set to an obtuse angle. This inclination angle provides greater operational space for inserting and removing the gas cylinder, facilitating the entry and exit of the gas cylinder. Specifically, the bottom of the gas cylinder can slide into and out of the cylinder position along the inclined surface of the first bend 22 and the second straight rod 23 when standing. Compared to a right-angle arrangement, this requires manual pulling or lifting of the gas cylinder to separate it from the bracket 2 or to stack it. Conversely, the included angle between the cross-section of the support 3 and the support rod 1 is set to a right angle, which ensures that the support 3 can provide stable vertical support for the gas cylinder body.

[0029] In addition, at the free end of the frame rod 1, i.e. the push handle end of the cart, the rod body forms a certain bending angle. This structure is more ergonomic, making it easier for users to hold and apply force, thereby easily pulling or pushing the cart.

[0030] The dual-cylinder trolley of this utility model significantly improves the efficiency and versatility of gas cylinder transportation by setting up a dual-cylinder bracket 2 and a multi-level support frame 3 that can adapt to gas cylinders of different heights. At the same time, by optimizing the angular relationship between the bracket 2, the support frame 3 and the frame rod 1, as well as the bottom support structure, the ease of operation, transportation stability and the trolley's own standing stability are effectively improved.

[0031] The method of using the dual-bottle trolley described in this utility model mainly includes three steps: loading, transportation, and parking. The specific operation is as follows: 1. Loading gas cylinders: The user pushes the cart to the vicinity of the gas cylinder and, taking advantage of the large operating space provided by the obtuse angle design between the bracket 2 and the support rod 1, tilts the first gas cylinder so that its bottom is aligned with a cylinder position on the bracket 2 (i.e., the space between the second straight rod 23 and the first bent part 22 on one side).

[0032] Place the bottom of the gas cylinder into the cylinder position and push it forward so that the cylinder body leans against the multiple supports 3 on one side of the support rod 1. The obtuse angle structure formed by the second bend 32 of the support 3 can naturally guide and wrap around the cylinder body, achieving lateral support.

[0033] Repeat the above operation to place the second gas cylinder into another cylinder position on the bracket 2. Since there are multiple support frames 3 arranged at intervals along the axial direction of the support rod 1, the cylinder body can always be effectively supported by at least one or more support frames 3, regardless of the height of the gas cylinder, thus adapting to gas cylinders of different heights and sizes.

[0034] 2. Transport gas cylinders: After both gas cylinders are securely placed, the user can hold the handle formed by bending the free end of the frame pole 1 and apply force backward and downward to make the wheels of the cart touch the ground. The entire cart is then easily lifted to an inclined transport posture with the rear wheel as the fulcrum.

[0035] At this point, the user can use the handle to pull or push the trolley to transfer both gas cylinders to the target location simultaneously. During the movement, the bracket 2 supports the bottom of the gas cylinder, and multiple supports 3 laterally restrict the gas cylinder body, effectively preventing the gas cylinder from rolling, shaking, or tipping over during transportation.

[0036] 3. Parking and Standing: When the cart reaches its destination and no further movement is needed, the user simply needs to release the handle or gently push the handle forward, and the cart will naturally fall back under the influence of gravity.

[0037] Since the lowest point of the free end of the first bend 22 of the bracket 2 is flush with the lowest point of the wheel, when the trolley is not in transport mode, it will be supported on the ground by the first bend 22 and the wheel, forming a stable standing posture, without needing to lean on any external object, thus safely and stably storing the gas cylinder.

[0038] In summary, this trolley, through its unique structural design, achieves simultaneous, efficient, safe, and stable transportation and storage of two gas cylinders.
