Description

Technical Field

[0001] This utility model relates to the field of gas cylinder protection technology, and in particular to a gas cylinder storage and transportation protection device. Background Technology

[0002] In the process of safe production in coal mines, hot welding is a common process in the processing of equipment and materials. Hot welding requires the use of flammable and explosive gases such as oxygen and acetylene. During the transportation and use of these two gases, there are often dangerous situations such as rolling and injuring people, gas leaks, and even acute poisoning. Inhaling high concentrations of acetylene may lead to acute poisoning.

[0003] Currently, gas cylinder transport protective devices (such as CN219296166U) are widely used to protect gas cylinders and improve their safety during transport and use. These devices include a movable base, limiting rails, and protective straps. The top of the limiting rails is covered to prevent the gas cylinders from being exposed to sunlight. One side of the limiting rails is open and shielded by the protective straps. The movable base supports and moves the gas cylinders, while the limiting rails, in conjunction with the protective straps, shield and limit the gas cylinders around their perimeter to prevent them from tilting and rolling during transport.

[0004] Existing protective devices for transporting gas cylinders require the cylinders to be moved directly from an opening on one side of the limiting barrier to the placement space enclosed by the barrier. Due to the restriction of the limiting barrier, the operating space is limited, making the handling difficult and hindering the workers from moving the cylinders into the placement space, thus affecting work efficiency and posing a high risk of falling during handling. In addition, relying solely on protective bandages to cover the opening side is prone to breakage and damage, resulting in poor limiting ability and high usage risks. Utility Model Content

[0005] To address the technical problems of existing gas cylinder transportation protection devices, which directly transport gas cylinders to the enclosed space of the protective structure, resulting in limited operating space, high transportation difficulty, limited protection capabilities, and high risk of falling, this utility model provides a gas cylinder storage and transportation protection device.

[0006] The technical solution of this utility model is as follows: This utility model provides a protective device for storing and transporting gas cylinders, including a box with an opening on one side. Several brake wheels are installed at the bottom of the box. A support base plate is horizontally fixed at the bottom of the box. A baffle is hinged to the side of the support base plate near the opening of the box. When the baffle is horizontal, it is located outside the box. When the baffle is vertical, it is located inside the box. A tray for supporting gas cylinders is slidably provided between the baffle and the support base plate. A partition is also fixedly installed inside the box. The partition is vertically arranged and forms two independent spaces for placing gas cylinders with the inner wall of the box. A first connecting ring is fixedly provided on the side of the partition near the baffle. A second connecting ring is fixedly installed on the baffle. A pin is detachably connected between the first connecting ring and the second connecting ring. The flip-up baffle extends out of the box when horizontally unfolded. Combined with a sliding tray, workers can first place the gas cylinders stably on the tray outside the box, then slide the tray along the baffle and supporting base into the box. This significantly expands the operating space, reduces handling difficulty, and improves work efficiency. The partition divides the box into two independent storage spaces, allowing for the separate storage of different gas cylinders and preventing collisions during transport, further reducing safety risks. The first and second connecting rings, along with the latch, work together to securely lock the baffle when it is vertically closed, replacing easily broken protective bandages and providing stronger limiting capabilities. Furthermore, the detachable latch design does not affect the normal flipping and use of the baffle.

[0007] Preferably, a first limiting block is fixedly provided on the inner wall of the box, and the first limiting block is provided with an arc-shaped limiting groove. The first limiting block is distributed on both sides of the partition and is set opposite to the opening side of the box. The arc-shaped limiting groove can fit against the outer wall of the gas cylinder to laterally limit the gas cylinder entering the box, preventing the gas cylinder from sliding along the length of the box due to bumps during transportation, further supplementing the limiting function and improving the stability of the gas cylinder placement.

[0008] Preferably, a first slide rail is provided on the baffle, and a second slide rail is provided on the support base plate. In the horizontal state, the upper surface of the baffle is flush with the upper surface of the support base plate, and the first and second slide rails are coaxially arranged. The pallet is slidably connected to the first and second slide rails through a slider. The coaxial slide rails and sliders cooperate to ensure that the pallet slides smoothly outside the box (on the baffle) and inside the box (on the support base plate), avoiding the pallet from jamming or tilting due to misalignment of the slide rails. At the same time, the flush surfaces make it easier for workers to push the pallet, improving the convenience of operation.

[0009] Preferably, a third limiting block is fixedly provided on the support base plate. The third limiting block is located at the end of the second slide rail away from the baffle. The third limiting block can block the pallet when it slides to a designated position inside the box, so as to prevent the gas cylinder from colliding with the inner wall of the box due to excessive sliding of the pallet, and further ensure the safety of the gas cylinder during handling and storage.

[0010] Preferably, a hook is fixedly installed on the inner wall of the box, and two chains are fixedly installed on the partition. The hook is provided with a hook that connects to the chains. The cooperation between the chains and the hooks can temporarily limit the gas cylinder inside the box, preventing the gas cylinder from sliding out and falling when the baffle is flipped, thus improving the safety of use.

[0011] Preferably, the partition is vertically fixed in the middle of the box. The centrally located partition ensures that the two independent placement spaces are the same size, which facilitates symmetrical storage of gas cylinders, ensures the overall center of gravity of the box is balanced, avoids the box tilting due to the offset of the gas cylinder storage position, and reduces the risk of the box tipping over during transportation.

[0012] Preferably, the lower surface of the baffle is provided with an installation groove, and a support rod is rotatably connected in the installation groove. The cross-section of the support rod is rectangular, and one end of the support rod is rotatably connected to the installation groove. The support rod is flipped toward the opening side close to the box body. When the baffle is horizontally unfolded, the support rod can be flipped from the installation groove to be perpendicular to the ground, forming a stable support for the baffle, avoiding the baffle from sagging or deforming due to excessive weight of the gas cylinder, and ensuring that the baffle remains horizontal when the tray slides.

[0013] Preferably, the box body has a door that rotates on the open side, with a window on the door. An air pipe opening is provided on the side wall of the box body. The door can be closed after the gas cylinder is stored, forming double protection to further isolate external impacts and prevent the gas cylinder from being affected by external factors. The window allows staff to observe the storage status of the gas cylinder inside the box at any time, and can confirm whether the gas cylinder is tilted or leaking without opening the box door, improving the convenience of inspection. The air pipe opening can be used to connect the air pipe of the gas cylinder, which can be operated without removing the gas cylinder, while avoiding the safety hazards caused by air pipe entanglement.

[0014] Preferably, two opposing support blocks are fixedly installed at the bottom of the box body, with the support blocks extending toward the interior of the box body. The support base plate is fixed to the support blocks with bolts. The support blocks provide a stable installation foundation for the support base plate. The bolt fixing method facilitates the disassembly and maintenance of the support base plate. When the support base plate or tray is damaged, it can be quickly disassembled and replaced, reducing maintenance costs.

[0015] Preferably, a second limiting block is fixed on both side walls of the partition. The second limiting block is located on one side of the first limiting block, which further restricts the lateral displacement of the gas cylinder from the partition side, preventing the gas cylinder from being squeezed towards the partition during transportation and preventing the gas cylinder from shaking too much in the independent space.

[0016] As can be seen from the above technical solutions, the advantages of this utility model are: 1. With the flip-up baffle, when the baffle is horizontally unfolded, it extends outside the box. In conjunction with the sliding tray, the staff can first place the gas cylinders stably on the tray outside the box, and then slide the tray along the baffle and the supporting base plate into the box. This greatly expands the operating space, reduces the difficulty of handling, and improves work efficiency. The cooperation of the first connecting ring, the second connecting ring and the pin allows the pin to firmly lock the baffle when it is vertically closed, replacing the easily broken protective bandage. It has a stronger limiting ability, and the detachable design of the pin does not affect the normal flipping and use of the baffle.

[0017] 2. A hook is fixedly installed on the inner wall of the box, and two chains are fixedly installed on the partition. The hook is equipped with a hook that connects to the chain. The cooperation between the chain and the hook can temporarily limit the gas cylinder inside the box to prevent the gas cylinder from sliding out and falling when the baffle is flipped, thus improving the safety of use.

[0020] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0021] Example 1 In a typical embodiment of this utility model, such as Figures 1-4 As shown, a protective device for storing and transporting gas cylinders is proposed, comprising: a housing 1, brake wheels 3, a first limiting block 4, a partition 6, a baffle 7, a first connecting ring 8, a second connecting ring 9, a pin 10, a supporting base plate 11, and a tray 14. Several brake wheels 3 are provided, installed at the bottom corners of the housing 1. The brake wheels 3 are existing universal wheels with braking function to facilitate the transfer and positioning of the housing 1. One side of the housing 1 has an opening for the gas cylinder to enter. The top of the housing 1... The top of the gas cylinder is sealed to prevent sunlight from shining on it. A first limiting block 4 is fixedly installed on the inner wall of the housing 1 and is positioned opposite to the opening side of the housing 1. The first limiting block 4 has an arc-shaped limiting groove 5 for limiting the position of the gas cylinder. A baffle 7 is hinged to the bottom of the opening side of the housing 1. The baffle 7 can switch between horizontal and vertical positions. When the baffle 7 is in the horizontal position, it is located outside the housing 1. When the baffle 7 is in the vertical position, it is located inside the housing 1.

[0022] The support base plate 11 is horizontally fixed at the bottom inside the box 1. The support base plate 11 is used to support the gas cylinder. The tray 14 is slidably connected to the baffle 7 and the upper surface of the support base plate 11. The gas cylinder is placed on the tray 14. Under the action of the tray 14, the gas cylinder can be transferred from the baffle 7 in a horizontal state to the support base plate 11, which facilitates the entry of the gas cylinder into the box 1.

[0023] The partition 6 is vertically fixed inside the housing 1. The partition 6 is located on one side of the first limiting block 4. The surface of the partition 6 is parallel to the side wall of the housing 1. The partition 6, together with the inner wall of the housing 1 and the first limiting block 4, forms an independent placement space for placing the gas cylinder, thereby restricting the position of the gas cylinder. The surface of the partition 6 is perpendicular to the surface of the baffle 7. A first connecting ring 8 is fixedly provided on the side of the partition 6 near the baffle 7. A second connecting ring 9 is fixedly installed on the baffle 7. A pin 10 is detachably connected between the first connecting ring 8 and the second connecting ring 9, thereby using the pin 10 to restrict the position of the baffle 7, so that the baffle 7 is in a vertically locked state. The baffle 7 then partially blocks the opening side of the housing 1, thereby working with the inner wall of the housing 1, the first limiting block 4 and the partition 6 to limit the periphery of the gas cylinder and prevent the gas cylinder from tipping over.

[0024] Specifically, the partition 6 is vertically fixed in the middle of the box 1, dividing the interior of the box 1 into two equal spaces. There are two first limiting blocks 4, which are fixed on the left and right sides of the partition 6, so that the box 1 can accommodate two gas cylinders at the same time. The first limiting blocks 4 are opposite to the opening side of the box 1, and the first limiting blocks 4 have limiting grooves 5. The limiting grooves 5 are arc-shaped and are used to limit the gas cylinders.

[0025] The support base plate 11 is fixedly installed at the bottom inside the box 1 by bolts. The bottom inside the box 1 is fixedly provided with support blocks 22. There are two support blocks 22, which are arranged opposite each other on both sides of the opening of the box 1. The support blocks 22 extend toward the inside of the box 1 to support and limit the support base plate 11. The support base plate 11 and the support blocks 22 are fixed together by bolts. The setting of the support blocks 22 can lift the support base plate 11 so as to facilitate the hinge between the support base plate 11 and the baffle 7 and avoid obstructing the flipping of the baffle 7.

[0026] The support base plate 11 is hinged to the baffle 7 on the side near the opening of the box 1 via a hinge (such as a hinge). The upper surface of the baffle 7 is provided with a first slide rail 12, and the upper surface of the support base plate 11 is provided with a second slide rail 13. Both the first slide rail 12 and the second slide rail 13 extend toward the interior of the box 1. When the baffle 7 is in a horizontal state, the upper surface is flush with the upper surface of the support base plate 11, and the first slide rail 12 and the second slide rail 13 are coaxially arranged at this time. The tray 14 is a disc structure, and a slider is fixedly provided at the bottom of the tray 14. The tray 14 is slidably connected to the first slide rail 12 and the second slide rail 13 through the slider, thereby realizing the sliding transfer between the baffle 7 and the support base plate 11 when the tray 14 is in a horizontal state.

[0027] In this embodiment, there are two sets of first slide rail 12 and second slide rail 13. The first slide rail 12 and the second slide rail 13 correspond one-to-one. The two sets of first slide rail 12 are spaced apart along the length of the baffle 7. Each set of first slide rail 12 is slidably connected to a tray 14.

[0028] A third limiting block 17 is fixedly provided on the supporting base plate 11. The third limiting block 17 is located at the end of the second slide rail 13 away from the baffle 7, so as to limit the tray 14 and ensure that the gas cylinder can be pushed into place. The third limiting block 17 is a flexible block structure.

[0029] In other embodiments, a rubber pad may be fixedly installed on the upper surface of the tray 14, which can serve as a buffer and increase the friction between the tray and the gas cylinder.

[0030] like Figure 2 and Figure 3 As shown, a mounting groove 23 is provided on the lower surface of the baffle 7. A support rod 15 is rotatably connected in the mounting groove 23. The support rod 15 can support the baffle 7 when it is in a horizontal state, so that the baffle 7 is in a stable horizontal state, which facilitates the movement of the tray 14. The cross-section of the support rod 15 is rectangular. One end of the support rod 15 is rotatably connected to the mounting groove 23. The free end of the support rod 15 is close to the opening side of the box 1. Due to the restriction of the rectangular shape, the support rod 15 can only be rotated within the range of 0-90°.

[0031] It is understood that there are several support rods 15. In other embodiments, the mounting groove 23 can be set as a rectangular insertion structure, and the support rod 15 can be set as a detachable structure that can be inserted into the mounting groove 23. In this case, when the support rod 15 is not needed, it can simply be removed and placed in the box 1.

[0032] In this embodiment, there is one first connecting ring 8 and two second connecting rings 9. The two second connecting rings 9 are arranged opposite each other, and the gap between the two second connecting rings 9 is used to accommodate the first connecting ring 8, so that the first connecting ring 8 and the second connecting ring 9 are coaxially arranged, which facilitates the insertion of the pin 10 to achieve locking between the baffle 7 and the partition 6.

[0033] The interior of the housing 1 is also fixedly provided with a second limiting block 16. The second limiting block 16 is fixedly set on one side of the first limiting block 4. Specifically, the second limiting block 16 is fixedly set on the two side walls of the partition 6 and located on one side of the first limiting block 4 to assist in the limiting of the gas cylinder.

[0034] In other embodiments, a hook 19 can be fixedly installed on the inner wall of the housing 1, and two chains 18 can be fixedly installed on the partition 6. The hook 19 is provided with a hook, and the free end of the chain 18 can be hooked on the hook. The chain 18 is used to temporarily limit the gas cylinder, preventing the gas cylinder from sliding out and falling when the baffle 7 is flipped, thus improving the safety of use.

[0035] The box body 1 is also equipped with a rotating door 2 on the opening side, which serves as an anti-theft door. The door 2 has a window 20, and the side wall of the box body 1 has an air pipe opening 21. The window 20 facilitates the observation of the gas cylinder inside the box body 1, and the air pipe opening 21 facilitates the extension of the gas cylinder's air pipe.

[0036] The specific working principle is as follows: After moving the gas cylinder storage and transportation protective device to the designated position, brake all the brake wheels 3 to restrict the position of the device. Then open the door 2, remove the latch 10, flip the vertical baffle 7 to the horizontal position, and unfold the support rod 15 to support the baffle 7. Pull the two trays 14 from the support base plate 11 inside the box 1 onto the baffle 7, then move the gas cylinder onto one of the trays 14 on the baffle 7, and manually push the tray 14 and the gas cylinder above it into the box 1. After pushing it into place, hook a chain 18 to temporarily limit the gas cylinder; then move the other gas cylinder onto the other tray 14 on the baffle 7 and push it into the box 1, and then hook another chain 18 to limit its movement. After both gas cylinders are pushed into the housing 1, the baffle 7 is flipped from a horizontal position to a vertical position, and the support rod 15 is stored. The pin 10 is then reinserted between the first connecting ring 8 and the second connecting ring 9 to lock the baffle 7, thus completing the storage of the gas cylinders. Finally, the housing door 2 is closed and the brake is released to transfer the device and its internal gas cylinders to the designated location. The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
