Description

Technical Field

[0001] The utility model relates to the technical field of gas cylinder safety protection, in particular to a cart capable of preventing gas cylinders from tipping over, and is applied to the transportation and use of gas cylinders during engineering construction. Background Art

[0002] A gas cylinder is a type of movable pressure vessel with a bottle-shaped main structure, generally filled with gas (which can be compressed gas, liquefied gas, dissolved or adsorbed gas, etc.). Gas cylinders are widely used, and are almost indispensable in both production and daily life. Gas cylinders are pressure-bearing equipment with explosion hazards, and the media they contain are generally flammable, explosive, toxic, and highly corrosive. The operating environment is more complex and harsh than that of other pressure vessels due to their mobility, repeated filling, unstable operators, and changing operating environments. Once a gas cylinder explodes or leaks, it often causes fire or poisoning, and even catastrophic accidents, resulting in serious property damage, casualties, and environmental pollution. To ensure the safe use of gas cylinders, in addition to requiring them to meet the general requirements for pressure vessels, certain special regulations and requirements are also required.

[0003] Conventional short-distance transport of gas cylinders can be done by manually tilting and rolling concave-bottom gas cylinders and gas cylinders with round bases. This method relies on the master's handling skills and careful precautions, which is not conducive to safe transportation over long distances and for a long time.

[0004] Gas cylinders such as oxygen and acetylene cylinders, used for metal welding and cutting, are frequently used and transported on construction sites. However, since these cylinders often contain compressed, flammable, and explosive gases, care must be taken to prevent collisions and cart tipping during transport. Gas cylinders are often tilted against a cart during use, or sleeves are welded on-site to position the cylinders upright for use.

[0005] In existing technology, most gas cylinders are placed directly on carts for use, which can easily lead to gas leakage, unstable air pressure, and even serious consequences such as fire and explosion. If the gas cylinders are to be placed upright, they need to be equipped with special anti-tip devices and must be moved on site, which is not only time-consuming and labor-intensive, but also poses certain safety risks.

[0006] For this reason we urgently need to provide a kind of cart that can prevent gas cylinder from toppling over. Utility Model Content

[0007] The technical problem to be solved by the utility model is to provide a cart capable of preventing gas cylinders from tipping over, thereby solving the problem that there is no anti-tipover measure when the gas cylinders are tilted or upright during use.

[0010] A further improvement of the technical solution of the present utility model is that: the support rod includes a telescopic support and a telescopic knob arranged at the lower part of the telescopic support; the telescopic support includes a thick sleeve and a thin rod plugged into the thick sleeve; a telescopic knob that limits the movement of the thin rod is provided at the connection between the thick sleeve and the thin rod.

[0011] A further improvement of the technical solution of the present invention is that: the number of the telescopic legs is two, and the structures of the two telescopic legs are the same as that of the support rod.

[0012] A further improvement of the technical solution of the present utility model is that the small wheel is a universal wheel with a brake mechanism.

[0013] A further improvement of the technical solution of the present utility model is that: the gas cylinder guard plate is a sideways-turned arc-shaped structure, and a keel is provided on the back side.

[0014] A further improvement of the technical solution of the present utility model is that movable joints are provided on the two cross bars connecting the telescopic legs to the vehicle body.

[0015] A further improvement of the technical solution of the present utility model is that: the handles are provided in two pieces, both of which are covered with rubber sleeves.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "several" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0038] The present invention will be described in further detail below with reference to the accompanying drawings and embodiments:

[0039] like Figure 1As shown, a cart capable of preventing a gas cylinder from tipping over comprises a body, a large wheel 8 arranged at the front end of the lower part of the body, a small wheel 7 arranged at the rear end of the lower part of the body, a gas cylinder guard plate 4 arranged at the upper part of the body, a bottom plate 10 arranged at the rear end of the body and a handle 5 arranged at the front end of the body, a retractable support rod is provided on the gas cylinder guard plate 4 through a buckle 3; the small wheel 7 is connected to the body through a telescopic leg 6; a cross bar connected to the body is also provided at the bottom of the telescopic leg 6; when the cart is upright, the support rod can be extended to touch the ground, the support rod is locked by the buckle 3, the telescopic leg 6 can be extended to make the cart upright, and the small wheel 7 is locked by the brake mechanism of the small wheel 7 to fix the cart.

[0040] Specifically, the entire cart is made of metal or other sturdy materials to withstand the wear and tear of daily use, ensuring the durability of the cart. The specific body, gas cylinder guard plate 4, base plate 10, support rod, telescopic legs 6, cross bar, etc. can be made of carbon steel or stainless steel. When made of carbon steel, the outer surfaces of the body, gas cylinder guard plate 4, base plate 10, support rod, telescopic legs 6, and cross bar can be painted with anti-rust paint to prevent rust. To reduce the overall weight of the cart, the body, gas cylinder guard plate 4, base plate 10, support rod, telescopic legs 6, cross bar, etc. can also be made of lightweight aluminum alloy. For aesthetic and durable purposes, the outer surfaces of the body, gas cylinder guard plate 4, base plate 10, support rod, telescopic legs 6, cross bar, etc. can also be painted with protective paint of various colors. When in use, the bottom of the gas cylinder is placed on the base plate 10, and the upper part of the gas cylinder is protected by the gas cylinder guard plate 4. The cart can then be used to push the gas cylinder to move or stand upright. When the gas cylinder is moved by pushing the cart, the gas cylinder will not shake or fall due to the provision of the gas cylinder guard plate 4, thereby ensuring the safety of the gas cylinder during movement; when the gas cylinder needs to be used upright on site, the cart can be fixed upright by providing a telescopic rod and telescopic legs 6, and locking it through the buckle 3 and the brake mechanism, thereby ensuring the uprightness of the gas cylinder, and having anti-dumping measures to ensure the safety of the gas cylinder in use.

[0041] Furthermore, the support rod includes a telescopic support 2 and a telescopic knob 1 provided at the lower portion of the telescopic support 2; the telescopic support 2 includes a thick sleeve and a thin rod plugged into the thick sleeve; a telescopic knob 1 is provided at the connection between the thick sleeve and the thin rod to limit the movement of the thin rod; the telescopic knob 1 can lock the thin rod and the thick sleeve. The structure of the telescopic knob 1 is as follows: Figure 5 When the support rod is needed, pull the thin rod out of the thick sleeve until it touches the ground. Find the support position, use telescopic knob 1 to lock the thick sleeve and thin rod together, and then use buckle 3 to lock the support rod. When the support rod is no longer needed, first loosen telescopic knob 1, insert the thin rod into the thick sleeve, and then use telescopic knob 1 to lock the thick sleeve and thin rod together to ensure that the thin rod does not fall out.

[0042] Further, the telescopic legs 6 are provided with 2 pieces. The structure of the 2 telescopic legs 6 is the same as that of the support rod, and also includes a thick sleeve and a thin rod inserted into the thick sleeve. A second telescopic knob for restricting the movement of the thin rod is provided at the connection between the thick sleeve and the thin rod. The second telescopic knob has the same structure as the telescopic knob 1, see Figure 5 . When the telescopic legs 6 are needed to support, loosen the second telescopic knob, pull out the thin rod of the telescopic leg 6 from the thick sleeve and extend it until the trolley can stand upright. Then tighten the second telescopic knob, and lock and fix the trolley wheels 7 through the braking mechanism of the trolley wheels 6 to fix the trolley and keep it upright, as Figure 1 shown. When the telescopic legs 6 are not needed to support, loosen the second telescopic knob, insert the thin rod into the thick sleeve, and the telescopic legs 6 return to their original state. Then tighten with the second telescopic knob, as Figure 2 shown.

[0043] Further, the trolley wheels 7 are universal wheels with a braking mechanism.

[0044] Further, as Figure 4 shown, the gas cylinder guard plate 4 is an arc-shaped structure that can be turned over sideways, and a keel is provided on the back side. The arc-shaped structure can match the outer contour of the gas cylinder, and the setting of the side-turning structure enables convenient opening and closing when placing and moving the gas cylinder. A keel is provided on the back side of the gas cylinder guard plate 4 to increase the strength of the gas cylinder guard plate 4. The specific structure of the keel can be set according to the actual situation. In this embodiment, it is set in the shape of a "king" character.

[0045] Further, as Figure 6-8 shown, movable joints 9 are provided on both of the 2 cross bars where the telescopic legs 6 are connected to the vehicle body. The setting of the movable joints 9 is to facilitate folding and storing the trolley and reduce the occupied space. When the trolley is in normal use, the movable joints 9 remain in their original state. When the trolley is no longer in use and needs to be put away for storage, adjust the movable joints 9 to be able to fold the cross bars at the movable joints 9, so that the trolley can be folded, ensuring that the trolley occupies a smaller space when stored.

[0046] Further, the handles 5 are provided with 2 pieces, and both are sleeved with rubber sleeves or anti-abrasion devices. The setting of the rubber sleeves ensures that the staff does not get their hands abraded when using the trolley, making it convenient to use.

[0047] Further, the large wheels 8 are provided with 2 pieces, and the diameter is 20 CM. The size of the large wheels 8 can be purchased and used according to the actual situation.

[0048] Further, the trolley wheels 7 are provided with 2 pieces, and the diameter is 7.5 CM. The size of the trolley wheels 7 can be purchased and used according to the actual situation.

[0049] Further, the width of the vehicle body is 34 CM; the width of the bottom plate 10 is 35 CM; the length of the bottom plate 10 is 22 CM.

[0050] Directions:

[0051] The utility model is provided with a retractable support rod and retractable legs on the cart. When using a gas cylinder, there is no need to equip an anti-dumping device separately, and the movement of the gas cylinder is also avoided. In this way, the cost is reduced and safety is effectively guaranteed. When using the gas cylinder, first stand the cart upright, open the telescopic support 2, rotate the telescopic knob 1 to extend the thin rod to directly touch the ground, and lock the buckle 3; rotate the second telescopic knob to extend the telescopic leg 6 to enable the cart to stand upright, and lock the small wheel 7 through the brake mechanism of the small wheel 7, thereby ensuring the uprightness of the cart and preventing the gas cylinder from tipping over. Figure 1 shown.

[0052] After the use of the gas cylinder, the telescopic knob 1 and the telescopic support 2 are restored to their original state, and the telescopic legs 6 are also restored to their original state. The cart can push the gas cylinder to move it to a storage place or to another place. Figure 2 shown.

[0053] After the cart is used, the movable joint 9 is adjusted to fold the cart for storage to reduce the space occupied by the cart. Figure 3 shown.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
