Description

Technical Field

[0001] This utility model relates to the field of transportation equipment technology. Background Technology

[0002] In industrial production, the safe transportation of oxygen and acetylene cylinders is of paramount importance. When using a three-wheeled motorcycle to transport cylinders, placing them horizontally poses a serious safety hazard. First, the vibrations and bumps during transport can cause the cylinders to roll, leading to mechanical collisions with other objects.

[0003] Such collisions may cause the following hazards: 1. The cylinder valve protection device (cylinder cap) is relatively weak and easily damaged in an impact, leading to high-pressure gas leakage; 2. When acetylene cylinders are laid horizontally, the acetone solvent that dissolves acetylene may flow out from the cylinder opening, not only reducing the safety of acetylene storage, but also because the flowing acetone is highly flammable; 3. Impacts to oxygen cylinders may damage their surface anti-corrosion layer, increasing the risk of corrosion during subsequent use. More seriously, if oxygen and acetylene leak simultaneously, they can easily form an explosive gas mixture. According to the relevant regulations of "Rubber Hoses for Welding, Cutting and Similar Operations with Gas Welding Equipment" and "Welding and Cutting Safety," gas cylinders should be kept upright during transportation, and reliable anti-tipping and anti-collision measures should be taken.

[0004] Therefore, it is essential to standardize transportation operations, use dedicated securing devices to ensure the gas cylinders are secure, and prevent rolling and collisions during transportation to guarantee operational safety. Utility Model Content

[0005] The purpose of this utility model is to provide a protective device for transporting oxygen and acetylene in order to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A protective device for transporting oxygen and acetylene includes a fixing frame, which includes a crossbeam and a vertical beam. The fixing frame is equipped with a cylinder fixing assembly and a vehicle positioning assembly. The cylinder fixing assembly includes a front vertical rod and a rear vertical rod on the vertical beam. The vehicle positioning assembly includes telescopic columns around the bottom of the fixing frame, which extend and abut against the side wall of the truck bed. The front vertical rod is equipped with a cylinder head fixing assembly, and the rear vertical rod is equipped with a cylinder tail fixing assembly. The cylinder is fixed between the cylinder head fixing assembly and the cylinder tail fixing assembly. The front vertical rod is higher than the rear vertical rod.

[0008] The above design uses a mounting frame consisting of horizontal and vertical beams. The cylinder fixing components form a support structure with front and rear vertical bars. The front vertical bar is higher to accommodate the conical head of the cylinder and elevate it. The telescopic column of the vehicle positioning component is adjustable in length, allowing it to press firmly against the side wall of the truck bed to prevent displacement during transport. The head and tail of the cylinder are respectively constrained by corresponding fixing components, ensuring the cylinder remains fixed. This design effectively solves the problems of cylinder rolling and collision caused by traditional horizontal transport through a three-dimensional spatial fixing method, while avoiding the risk of acetone leakage caused by horizontally placed acetylene cylinders.

[0009] Furthermore, the front vertical rod and the rear vertical rod are each provided with two sets symmetrically, and the gas cylinder head fixing component and the gas cylinder tail fixing component are each provided with two sets symmetrically.

[0010] The above scheme, through the symmetrical arrangement of two sets of front and rear vertical bars and corresponding fixing components, forms a dual-point support structure. This layout can support two gas cylinders at a time, while also ensuring more balanced force distribution on the cylinders. It achieves self-locking instantly upon placement, significantly improving loading and unloading efficiency.

[0011] Furthermore, the gas cylinder head fixing assembly and the gas cylinder tail fixing assembly have the same structure. The gas cylinder head fixing assembly includes a fixing plate located at the top of the front vertical rod. The fixing plate is provided with a hinge, and a clamp is connected to the other side of the hinge.

[0012] The above solution connects the fixing plate to the clamp via a hinge, forming an openable and closable ring-shaped constraint mechanism. The clamp can be rotated around the hinge to open, facilitating quick loading and unloading of the gas cylinder; when closed, it forms a ring-shaped locking structure together with the fixing plate. This achieves a balance between convenient loading and unloading of the gas cylinder and secure fixing, significantly improving operational efficiency compared to traditional strap-type fixing.

[0013] Furthermore, the fixing plate is arc-shaped and has padding layers distributed on its inner arc surface, and the clamp has an isolation pad disposed inside along its length.

[0014] The above solution uses an arc-shaped design for the fixing plate to fit the contour of the gas cylinder, and the inner arc-shaped pad (such as rubber or polyurethane) can buffer vibration and impact; the isolation pad inside the clamp prevents metal from directly contacting the cylinder and causing scratches.

[0015] Furthermore, the vehicle positioning component also includes a receiving groove at the bottom of the fixing frame, the telescopic column is slidably embedded in the receiving groove, and a clamping component is located in the receiving groove, the clamping component having a tendency to cause the telescopic column to extend out of the receiving groove.

[0016] The above-described design allows the telescopic column to slide and extend via a receiving groove, accommodating truck beds of different sizes. The locking assembly ensures the telescopic column always tends to extend outwards, automatically pressing against the side wall of the truck bed.

[0017] Furthermore, the clamping assembly includes a tension spring disposed in the receiving groove, one end of the tension spring being fixed to the inside of the receiving groove and the other end being fixed to the end of the telescopic column. The clamping assembly also includes a travel groove disposed on the upper end face of the receiving groove, a plurality of vertically arranged slots being provided on one side of the travel groove, and a sliding column embedded in the travel groove being provided on the telescopic column, with the slots located within the movement trajectory of the sliding column.

[0018] The above design utilizes a tension spring to provide continuous thrust, ensuring tight contact between the telescopic column and the truck bed. The sliding column moves along the travel groove to the locking slot, forming a mechanical interlock to prevent springback and loosening. The multi-stage locking slot design allows for graded adjustment according to the truck bed width, balancing adjustment precision and ease of operation.

[0019] Furthermore, the mounting frame is equipped with an alarm, the alarm is equipped with a switch pin, and the switch pin is equipped with a magnetic suction cup that adheres to the inner wall of the truck bed.

[0020] The above solution adds a safety warning function. The alarm is magnetically attached to the inner wall of the truck bed. When the mounting bracket shifts due to severe shaking, the magnetic suction cup detaches from the truck bed, triggering a switch pin and activating an audible and visual alarm. This design provides secondary protection, allowing real-time monitoring of the device's fixed status and compensating for the monitoring blind spots of purely mechanical fixation.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This utility model has a simple structure. The front vertical rod is relatively high to accommodate the conical head of the gas cylinder and simultaneously elevate the cylinder head. The telescopic column of the vehicle positioning component is adjustable in length, allowing it to press firmly against the side wall of the truck bed to prevent the device from shifting during transportation. The head and tail of the gas cylinder are respectively constrained by corresponding fixing components to ensure that the gas cylinder remains in a fixed state. This design effectively solves the problems of gas cylinder rolling and collision caused by traditional horizontal transportation through a spatial three-dimensional fixing method, while avoiding the risk of acetone leakage caused by horizontally placed acetylene cylinders.

[0023] 2. The alarm is attached to the inner wall of the truck bed via a magnetic suction cup. When the mounting bracket shifts due to severe shaking, the magnetic suction cup detaches from the truck bed, triggering the switch pin and activating the audible and visual alarm. This design provides secondary protection and real-time monitoring of the device's fixed status, compensating for the monitoring blind spots of purely mechanical fixation.

[0028] 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.

[0029] 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.

[0030] Example 1

[0031] like Figures 1 to 3 As shown, this embodiment provides a protective device for the safe transportation of oxygen and acetylene cylinders. The implementation of the present invention will be described in detail below with reference to specific embodiments.

[0032] The protective device mainly consists of three parts: a fixing frame 11, a gas cylinder fixing assembly, and a vehicle-mounted positioning assembly. The fixing frame 11 is welded from robust metal and includes a horizontally positioned crossbeam 12 and a vertically positioned vertical beam 13. Two sets of front vertical bars 14 and rear vertical bars 15 are symmetrically arranged. The front vertical bar 14 has a gas cylinder head fixing assembly, and the rear vertical bar 15 has a gas cylinder tail fixing assembly. The gas cylinder fixing assembly adopts a front-to-rear split design, with the front vertical bar 14 slightly higher than the rear vertical bar 15. This structural design better adapts to the natural shape of the gas cylinder. The symmetrical arrangement of the two sets of front and rear vertical bars 15 and their corresponding fixing assemblies forms a dual-point support structure. This layout can support two gas cylinders at a time while ensuring more balanced force distribution on the cylinders.

[0033] The cylinder head fixing assembly includes a fixing plate 17 located at the top of the front vertical rod 14. A hinge 18 is provided on the fixing plate 17, and a clamp 19 is connected to the other side of the hinge 18. The cylinder head fixing assembly and the cylinder tail fixing assembly have the same structure. The fixing plate 17 is arc-shaped and has a pad layer distributed on the inner arc surface. An isolation pad is provided inside the clamp 19 along the length direction.

[0034] The vehicle positioning component also includes a receiving groove 20 at the bottom of the fixing frame 11. The telescopic column 16 slides into the receiving groove 20. A clamping component is located within the receiving groove 20, and the clamping component tends to cause the telescopic column 16 to extend out of the receiving groove 20. The clamping component includes a tension spring 21 located within the receiving groove 20. One end of the tension spring 21 is fixed to the inside of the receiving groove 20, and the other end is fixed to the end of the telescopic column 16. The clamping component also includes a travel groove 22 on the upper surface of the receiving groove 20. Several vertically arranged slots 23 are provided on one side of the travel groove 22. A sliding column 24 is provided on the telescopic column 16, which is embedded in the travel groove 22. The slots 23 are located within the movement trajectory of the sliding column 24. The telescopic column 16 achieves sliding extension and retraction through the receiving groove 20, which can adapt to different sizes of truck beds. The locking assembly ensures that the telescopic column 16 always tends to extend outward, automatically pressing against the side wall of the truck bed. The tension spring 21 provides continuous thrust, ensuring tight contact between the telescopic column 16 and the truck bed. The sliding column 24 moves along the travel groove 22 to the locking slot 23, forming a mechanical interlock to prevent springback and loosening. The multi-stage locking slot 23 design allows for graded adjustment according to the width of the truck bed, balancing adjustment accuracy and ease of operation.

[0035] In practical applications, the operator first places the device stably inside the cargo bed of the transport vehicle. At this time, the adjustable outriggers of the vehicle positioning component automatically extend outward under the action of internal springs until they are firmly against the four sides of the cargo bed. The locking mechanism on the outriggers will automatically fix the position through the slots 23 to ensure that the entire device will not shift during transportation.

[0036] When loading gas cylinders, the curved design of the fixing plate 17 conforms to the contour of the gas cylinder, and the inner curved surface padding (such as rubber or polyurethane) can buffer vibration and impact. The isolation pad inside the clamp 19 prevents metal from directly contacting the cylinder body and causing scratches. The operator only needs to open the clamp 19 on the front vertical rod 14, place the gas cylinder vertically into the fixed position, so that the head of the gas cylinder naturally fits against the fixing plate 17 of the front support rod, and the tail is firmly placed on the fixing plate 17 at the tail. The fixing plate 17 is lined with shock-absorbing rubber pads, and the inside of the clamp 19 is also provided with a buffer padding layer. These flexible materials can effectively absorb the vibration during transportation and prevent metal parts from directly contacting the surface of the gas cylinder and causing damage.

[0037] An alarm 25 is installed on the mounting bracket 11, and a switch pin 26 is installed on the alarm 25. A magnetic suction cup 27, which adheres to the inner wall of the truck bed, is installed on the switch pin 26. This adds a safety warning function. The alarm 25 is attached to the inner wall of the truck bed via the magnetic suction cup 27. When the mounting bracket 11 shifts due to severe shaking, the magnetic suction cup 27 detaches from the truck bed, triggering the switch pin 26 and activating the audible and visual alarm. This design provides secondary protection, real-time monitoring of the device's fixed status, and compensates for the monitoring blind spots of purely mechanical fixation.

[0038] When the transport vehicle encounters bumpy roads, the multiple safety features of this protective device play a crucial role. First, the adjustable outriggers at the bottom of the frame continuously maintain pressure on the side walls of the truck bed, preventing the device from sliding or shifting. Second, the gas cylinders are securely fixed between the front and rear support rods, completely eliminating the risk of cylinder rolling and collisions common in traditional transport methods. Notably, the acetylene cylinders remain upright at all times, fundamentally eliminating the possibility of acetone leakage. Furthermore, the device is equipped with an intelligent alarm system; when severe bumps cause the fixing devices to loosen, a magnetic sensor immediately triggers an audible and visual alarm, reminding the driver to stop and check immediately.

[0039] This protective device is not only safe and reliable, but also extremely easy to operate. Loading and unloading gas cylinders can be completed simply by opening and closing the clamp 19, greatly improving work efficiency. The device's adjustable design allows it to adapt to transport vehicles of different sizes, demonstrating excellent versatility. Practical application has proven that this device effectively addresses various safety hazards during the transportation of oxygen and acetylene cylinders, fully complying with relevant national safety regulations.

[0040] It should be noted that the connection relationships of components not specifically mentioned in this application are all assumed to be based on existing technology. Since they do not involve the inventive point and are commonly used in existing technology, the structural connection relationships are not described in detail.
