Description

Technical Field

[0001] This utility model relates to the field of bottled gas transportation technology, and more specifically, to a protective device for bottled gas transportation. Background Technology

[0002] In current bottled gas transportation processes, cylinders are typically placed in the transport vehicle using upright stacking or single-layer frame fixing methods. Specifically, multiple cylinders are arranged vertically along the axis and secured with wooden or metal frames and strapping. Cushioning materials such as foam and sawdust are filled between the cylinders. However, this protection method has significant drawbacks: in bumpy road conditions or during emergency braking, the rigid fixing structure of the traditional frame cannot effectively absorb impact energy. Cylinders are prone to rigid collisions with the frame or adjacent cylinders, leading to damage to the cylinder valves, fatigue cracks in the cylinder body, or even structural damage, resulting in gas leaks. Furthermore, the filling materials also incur additional usage costs. Utility Model Content

[0003] To overcome the above deficiencies, this utility model provides a protective device for the transportation of bottled gas, which solves the aforementioned problems.

[0004] This utility model is implemented as follows:

[0005] A protective device for transporting bottled gas includes a fixing frame, the fixing frame including a base, a shock-absorbing base provided on the top of the base, three sets of I-beam columns arranged along the length of the top of the base, a crossbar provided between each set of I-beam columns, a first limiting plate provided between any two adjacent crossbars, two connecting parts provided on the outer side of each I-beam column, and the connecting parts on each I-beam column are of equal height, and two second limiting plates are provided at the connecting parts of the same height on the left and right sides of the fixing frame.

[0006] In this embodiment, there are 6 shock-absorbing bases, which are detachably mounted on the top of the base. The top of the shock-absorbing base is provided with two circular protrusions, and the top of the circular protrusions is a concave portion.

[0007] In this embodiment, the shock-absorbing base is a composite structure of neoprene rubber and steel plate, and the circular boss is made of natural rubber.

[0008] In this embodiment, the top of the crossbars at both ends of the top of the fixing frame is provided with a lifting ring.

[0009] In this embodiment, the first limiting plate includes a first connecting plate disposed between any two adjacent crossbars, and three first arc-shaped plates are equidistantly disposed at both ends of the first connecting plate, with an elastic shaft disposed on the inner side of the first arc-shaped plate.

[0010] In this embodiment, the elastic shaft includes a movable shaft, one end of which is provided with an abutment plate, and the other end of which extends from the inner side of the first arc-shaped plate to the outer side and is provided with a limit nut. An abutment spring is provided between the inner side of the first arc-shaped plate and the abutment plate.

[0011] In this embodiment, the second limiting plate includes an I-beam mounting rod, a second connecting plate is provided on one side of the I-beam mounting rod, a second arc plate identical to the first arc plate is provided at the edge of the second connecting plate, and the same elastic shaft is provided on the second arc plate.

[0012] In this embodiment, the connecting part is a right-angle limiting plate, which is welded to the outside of the I-beam column. A reinforcing rib is provided between its bottom and the I-beam. The I-beam mounting rod is embedded in three right-angle limiting plates on the same side and at the same height.

[0013] In this embodiment, the threaded clamp at the connection part includes an L-shaped connecting arm, one end of which is fixed to the outside of the I-beam column, and the other end of which has a threaded connection part. The threaded connection part is threadedly connected to a hand-tightening screw. The I-beam mounting rod is placed on the L-shaped connecting arm, and the hand-tightening screw is rotated so that its end abuts against the I-beam mounting rod.

[0014] In this embodiment, a pad is provided at the junction of the I-beam mounting rod and the I-beam column.

[0015] The beneficial effects of this utility model are as follows: The protective device achieves protection through a dual mechanism of frame constraint and elastic shaft. The I-beam column and the crossbar form the main support frame. The arc-shaped plates on the first and second limiting plates, together with the elastic shaft, form a flexible clamp on the gas tank from the horizontal direction. The bottom shock-absorbing base fits into the arc of the bottom of the bottle to form a three-point support. When transportation vibration occurs, the spring compression of the elastic shaft absorbs the radial impact energy, and the rubber base disperses the vertical vibration through damping deformation, thus achieving multi-dimensional vibration reduction.

[0023] 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, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0024] 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.

[0025] like Figure 1-2As shown, this utility model provides a protective device for transporting bottled gas, including a fixing frame 10. The fixing frame 10 includes a base 11, and a shock-absorbing base 15 is provided on the top of the base 11. Three sets of I-beam columns 12 are provided along the length of the top of the base 11. A crossbar 13 is provided between each set of I-beam columns 12. A first limiting plate 20 is provided between any two adjacent crossbars 13. Two connecting parts 14 are provided on the outer side of each I-beam column 12, and the connecting parts 14 on each I-beam column 12 are of equal height. Two second limiting plates 30 are provided at the connecting parts 14 of the same height on the left and right sides of the fixing frame 10. The first limiting plate 20 and the second limiting plate 30 ensure the horizontal fixation of the bottled gas. At the same time, the elastic shaft 23 provides a shock-absorbing effect, and the shock-absorbing base 15 at the bottom also protects the bottled gas.

[0026] Specifically, the top of the mounting bracket 10 is provided with several angle steels that divide it into 6 grooves for installing the shock-absorbing base 15. The shock-absorbing base 15 is fixed in these grooves with bolts. Furthermore, the top of the shock-absorbing base 15 is provided with two circular bosses. The top of the circular bosses is a concave part. This concave part is used to fit the arc-shaped bottom of the gas tank to increase stability.

[0027] As a preferred embodiment, the shock-absorbing base 15 is a composite structure of neoprene rubber and steel plate. Neoprene rubber has excellent damping performance and can effectively absorb low-frequency vibration energy, while the steel plate enhances the overall load-bearing capacity. The circular boss is made of natural rubber, which ensures close contact with the bottom of the gas tank and further enhances the shock absorption and protection effect.

[0028] In this embodiment, the top of the crossbars 13 at both ends of the top of the fixed frame 10 is provided with lifting rings 1301. These two lifting rings 1301 facilitate the hoisting of the fixed frame 10, making it easier to transport it on the ground and unload it from the vehicle.

[0029] like Figure 2-3 As shown, the first limiting plate 20 includes a first connecting plate 21 disposed between any two adjacent crossbars 13. Three first arc-shaped plates 22 are equidistantly disposed at both ends of the first connecting plate 21. An elastic shaft 23 is disposed on the inner side of the first arc-shaped plate 22. The elastic shaft 23 includes a movable shaft 2301. One end of the movable shaft 2301 is provided with an abutment plate 2302. The other end of the movable shaft 2301 passes through the inner side of the first arc-shaped plate 22 to the outer side and is provided with a limiting nut 2303. An abutment spring 2304 is disposed between the inner side of the first arc-shaped plate 22 and the abutment plate 2302.

[0030] Furthermore, the second limiting plate 30 includes an I-beam mounting rod 31, a second connecting plate 32 is provided on one side of the I-beam mounting rod 31, and a second arc plate 33 identical to the first arc plate 22 is provided at the edge of the second connecting plate 32, and the same elastic shaft 23 is provided on the second arc plate 33.

[0031] It should be noted that the adjacent first arc plate 22 and second arc plate 33 are symmetrically arranged in the horizontal direction. At the same time, in the top view, the center point of their symmetry coincides with the circle of the circular boss on the bottom shock-absorbing base 15. That is, each such combination is a mounting position for a bottled gas. The elastic shaft 23 on each mounting position elastically abuts against the outer surface of the gas tank, that is, it provides clamping and fixing, and can effectively reduce the radial impact on the gas tank itself.

[0032] In one embodiment, such as Figure 4 As shown, the connecting part 14 is a right-angle limiting plate 1401, which is welded to the outside of the I-beam column 12. A reinforcing rib is provided between its bottom and the I-beam. The I-beam mounting rod 31 is embedded in three right-angle limiting plates 1401 on the same side and at the same height. When in use, several gas cylinders are placed on the shock-absorbing base 15 and leaned against the first limiting plate 20. At this time, the second limiting plate 30 is installed in sequence, that is, the second limiting plate 30 is squeezed until the I-beam mounting rod 31 can be embedded in the right-angle limiting plate 1401.

[0033] In another embodiment, such as Figure 5 As shown, the connecting part 14 has a threaded clamp 1402. The threaded clamp 1402 includes an L-shaped connecting arm 14021, one end of which is fixed to the outside of the I-beam column 12, and the other end has a threaded connecting part 14022. The threaded connecting part 14022 is threadedly connected to a hand-tightening screw 14023. The I-beam mounting rod 31 is placed on the L-shaped connecting arm 14021. The hand-tightening screw 14023 is rotated so that its end abuts against the I-beam mounting rod 31. In use, after the gas tank is placed, the I-beam mounting rod 31 is placed on the three L-shaped connecting arms 14021. At this time, the hand-tightening screw 14023 is adjusted in sequence to clamp it. Compared with the method of the right-angle limiting plate 1401, this adjustment and fixing is more labor-saving.

[0034] In this embodiment, a pad 34 is provided at the junction of the I-beam mounting rod 31 and the I-beam column 12. The pad 34 reduces the squeezing and collision between the I-beam mounting rod 31 and the I-beam column 12, thus protecting the structural stability of both.

[0035] The present invention has been further described above with reference to specific embodiments. However, it should be understood that the specific description herein should not be construed as limiting the substance and scope of the present invention. Various modifications made by those skilled in the art to the above embodiments after reading this specification are all within the scope of protection of the present invention.
