Description

Technical Field

[0001] This utility model belongs to the field of tooling and auxiliary equipment technology, and in particular relates to a simple anti-tipping device for acetylene cylinders. Background Technology

[0002] Acetylene cylinders contain packing material and acetone. When laid horizontally, acetone will leak out with the acetylene gas, increasing consumption and lowering combustion temperature, thus affecting performance. Furthermore, leaked acetone mixed with air may form an explosive mixture, potentially igniting and exploding upon contact with an open flame. Additionally, the anti-vibration rubber rings on acetylene cylinders are designed to prevent collisions during loading, unloading, transportation, and use. These rings are insulating; when laid horizontally, the cylinder is essentially placed on an electrical insulator. Static electricity generated on the cylinder cannot dissipate to the ground and accumulates, easily generating static sparks. In the event of an acetylene leak, this can easily lead to combustion and explosion. During use, the cylinder valve is equipped with a pressure regulator, flame arrester, and connecting hose. Laying horizontally can cause the cylinder to roll, potentially damaging the pressure regulator, flame arrester, or detaching the connecting hose, leading to acetylene leakage and potentially causing combustion and explosion.

[0003] Therefore, acetylene cylinders must be placed upright during use to avoid various safety hazards caused by lying them down. Currently, various anti-tipping devices for acetylene cylinders have appeared on the market. Although they can protect acetylene cylinders from tipping over, their complex structure not only increases production costs and difficulty, but also makes the movement and storage of the anti-tipping devices themselves inconvenient.

[0004] Based on these issues, it is of great practical significance to develop an acetylene cylinder anti-tipping device that is simple in structure, easy to move, and safe and reliable. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model provides a simple acetylene cylinder anti-tipping device that is easy to replace, safe, and reliable. It avoids safety accidents caused by acetylene cylinder tipping due to improper operation during cutting and welding, and greatly improves the safety of the operation process.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: A simple anti-tipping device for acetylene cylinders includes a base and a protective cylinder. The interior of the protective cylinder serves as a space for containing the cylinder. The protective cylinder is mounted on the base, and the diameter of the base is at least twice the diameter of the protective cylinder. The protective cylinder is formed by a first arc member and a second arc member, which together form a cylindrical shape. One end of the first arc member and one end of the second arc member are hinged together by a pin. The first arc member is welded to the base, and the second arc member can rotate freely. The other end of the first arc member and the other end of the second arc member are locked together by a locking device.

[0007] Furthermore, the height of the protective cylinder is at least half the height of the acetylene cylinder.

[0008] Furthermore, the base is made of 5-6mm thick steel plate and is circular in shape.

[0009] Furthermore, the circumference of the first arc component is 3 / 5 of the circumference of the protective cylinder, and the chord length of the first arc component is slightly larger than the diameter of the acetylene cylinder.

[0010] Furthermore, the circumference of the second arc component is 2 / 5 of the circumference of the protective cylinder, and the chord length of the second arc component is slightly larger than the diameter of the acetylene cylinder.

[0011] Furthermore, a first pin sleeve is welded to the middle position of the outer side of one side of the first arc-shaped component, and a second pin sleeve is welded to the upper and lower positions of the outer side of one side of the second arc-shaped component. A pin passes through the first pin sleeve and the two second pin sleeves, so that the first arc-shaped component and the second arc-shaped component are hinged.

[0012] Furthermore, the locking device includes a stop block and a locking handle. The stop block is mounted on the first arc member, and a groove is formed between the stop block and the first arc member. One end of the locking handle is rotatably mounted on the second arc member by a pin. The locking handle is inserted into the groove to lock the first arc member and the second arc member.

[0013] Furthermore, the main body of the locking handle is arc-shaped, and the other end of the locking handle is provided with a handle head, and the locking handle has an L-shaped structure.

[0014] The advantages and positive effects of this utility model are: 1. The simple acetylene cylinder anti-tipping device described in this utility model is assembled and welded using stock steel plates, which has low manufacturing cost, uses few materials, is lightweight, has a simple structure, and is easy to move and use on site.

[0015] 2. The simple acetylene cylinder anti-tipping device described in this utility model places the acetylene cylinder inside a protective cylinder and has a locking device for locking and protection, which can effectively prevent the acetylene cylinder from tipping over due to external force and ensure the inherent safety of on-site cutting operations.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 5As shown, this embodiment provides a simple anti-tipping device for acetylene cylinders, comprising: a base 1 and a protective cylinder 2. The protective cylinder 2 is mounted on the base 1 and is formed into a cylindrical shape by a first arc member 201 and a second arc member 204. One end of the first arc member 201 and one end of the second arc member 204 are hinged together by a pin 3. The first arc member 201 is welded to the base 1. The interior of the protective cylinder 2 serves as a space for the cylinder. The inner diameter of the protective cylinder 2 is 30mm larger than the outer diameter of the acetylene cylinder 20 to prevent the acetylene cylinder 20 from tipping over due to excessive shaking inside the protective cylinder 2. To facilitate the placement of the acetylene cylinder 20 into the protective cylinder 2, the second arc member 204 can rotate freely. The other end of the first arc member 201 and the other end of the second arc member 204 are locked together by a locking device. The diameter of the base 1 is at least twice the diameter of the protective cylinder 2, increasing the contact area between the base and the ground and further reducing the risk of the cylinder tipping over.

[0023] In a preferred embodiment, the height of the protective cylinder 2 is at least half the height of the acetylene cylinder 20, ensuring that the acetylene cylinder 20 can be stably placed inside the protective cylinder 2.

[0024] In a preferred embodiment, the base 1 is made of 5-6mm thick ordinary stock steel plate, which is circular in shape and easy to obtain.

[0025] In a preferred embodiment, the circumference of the first arc member 201 is 3 / 5 of the circumference of the protective cylinder 2, and the chord length of the first arc member 201 is slightly larger than the diameter of the acetylene cylinder 20. The circumference of the second arc member 204 is 2 / 5 of the circumference of the protective cylinder 2, and the chord length of the second arc member 204 is slightly larger than the diameter of the acetylene cylinder 20. The protective cylinder 2 only needs to open 2 / 5 of the arc length of the movable side to form a sufficiently large opening, allowing the acetylene cylinder 20 to slide in or out almost against the inner wall of the fixed side, enabling smooth operation even in space-constrained environments. Furthermore, since most of the protective cylinder 2 is welded to the base, its overall torsional and deformation resistance is far superior to the "half-circle + half-circle" structure.

[0026] In a preferred embodiment, a first pin sleeve 202 is welded to the middle position of the outer side of one side of the first arc member 201, and a second pin sleeve 205 is welded to the upper and lower positions of the outer side of one side of the second arc member 204. A pin 3 passes through the first pin sleeve 202 and the two second pin sleeves 205, so that the first arc member 201 and the second arc member 204 are hinged. The two arc members have low manufacturing cost and are easy to assemble and disassemble.

[0027] In a preferred embodiment, the locking device includes a stop block 203 and a locking handle 4. The stop block 203 is mounted on the first arc member 201 and has an L-shaped structure. A groove is formed between the stop block 203 and the first arc member 201. One end of the locking handle 4 is rotatably mounted on the second arc member 204 via a pin 5. The locking handle 4 is inserted into the groove to lock the first arc member 201 and the second arc member 204. By rotating the locking handle 4 and inserting it into the groove, the first arc member 201 and the second arc member 204 can be locked, making it convenient to open and close the second arc member 204.

[0028] In a preferred embodiment, the main body of the locking handle 4 is arc-shaped, and the other end of the locking handle 4 is provided with a handle head. The locking handle 4 has an L-shaped structure. The arc-shaped locking handle body can fit well with the protective cylinder 2 to lock the first arc part 201 and the second arc part 204. To rotate the locking handle, simply pinch the handle head, which is convenient.

[0029] In use, the second arc-shaped part 204 can be opened freely. After the acetylene cylinder 20 is placed into the cylinder receiving space of the protective cylinder 2, the second arc-shaped part 204 is closed, and then the locking handle 4 is rotated into the insertion groove of the stop block 203.

[0030] This utility model provides a simple anti-tipping device for acetylene cylinders. It ensures that the acetylene cylinder 20 is upright during use. To use, open the locking handle 4 and the second arc-shaped component 204, insert the acetylene cylinder through the opening of the first arc-shaped component 201, then close the second arc-shaped component 204 and the locking handle 4. At this point, the acetylene cylinder is placed inside the anti-tipping device. Since the gap between the inner diameter of the protective cylinder 2 of the anti-tipping device and the outer diameter of the acetylene cylinder 20 is approximately 30mm, and the height of the protective cylinder 2 is half the height of the acetylene cylinder 20, the acetylene cylinder is essentially fixed in place. This allows for easy insertion of the acetylene cylinder into the anti-tipping device and prevents it from tipping over during use.

[0031] The acetylene cylinder anti-tipping device in the above embodiment can effectively prevent the acetylene cylinder from tipping over during use. However, for cylinders with large self-weight or cylinders subjected to strong impacts, there is still a risk of tipping over. To further reduce the risk of tipping over, the base diameter is 3-4 times the outer diameter of the acetylene cylinder to increase the contact area between the base and the ground.

[0032] This utility model presents a simple anti-tipping device for acetylene cylinders, which is entirely constructed using surplus steel plates from existing stock. The plates are cut, bent, and welded together, resulting in low cost and simple manufacturing. It has been applied in gas cutting operations with good performance and demonstrates significant potential for wider adoption.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
