Description

Technical Field

[0001] This utility model belongs to the field of hydrogen storage and transportation technology, specifically relating to an anti-tipping device for hydrogen storage and transportation equipment. Background Technology

[0002] Hydrogen storage and transportation units, typically referring to long-tube trailers, are the core equipment for transporting high-pressure hydrogen. Their structure consists of multiple large, seamless steel cylinders connected in parallel and fixed to a semi-trailer chassis. Outriggers are crucial load-bearing and safety features used to ensure the vehicle's stability when stationary. Under long-term alternating loads, fatigue cracks may develop at stress concentration points. Accidental impacts from other vehicles within the factory area can cause deformation and damage to the outrigger structure. Damage to the outriggers can cause the hydrogen storage and transportation unit to tilt forward, leading to the breakage of mechanical connecting pipes, gas leaks, damage to valves, instruments, and other precision components, resulting in significant property damage and personal injury. Existing outriggers use mechanical dual-speed manual lifting outriggers, employing electric, hydraulic systems, or gearboxes in conjunction with manual operation, resulting in high manufacturing and maintenance costs. If one outrigger fails, the entire support system will collapse.

[0003] In summary, existing technologies have the problem that hydrogen storage and transportation devices may tilt forward and cause safety accidents if the outriggers are accidentally damaged. Utility Model Content

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0005] Therefore, the purpose of this utility model is to provide an anti-tipping device for hydrogen storage and transportation devices, which can solve the problem that in the prior art, when the outriggers are accidentally damaged, the hydrogen storage and transportation device will tilt forward, causing a safety accident. This utility model provides an anti-tipping device for hydrogen storage and transportation devices, which includes a top plate, a left support frame, and a right support frame. The outer edges of the left and right support frames coincide with the bottom wide edge of the top plate and are perpendicular to the top plate. The bottom of the left and right support frames are connected by a base plate. The length of the base plate and the sum of the widths of the left and right support frames are equal to the length of the top plate. The left and right support frames have the same structure, both being isosceles triangles on the sides. A horizontal bar parallel to the bottom length of the left and right support frames is placed on the isosceles triangle. The top plate, base plate, left support frame, and right support frame are all welded together. The width of the top plate is twice the width of the left support frames.

[0006] Optionally, a handle is provided at the middle position of the long side of the top plate.

[0014] The following is in conjunction with the appendix Figure 1-3 This utility model will be described in further detail below.

[0015] Example 1, refer to Figure 1-3 In this embodiment, to address the problem in existing technologies where the hydrogen storage and transportation device tilts forward and causes a safety accident when the outriggers are accidentally damaged, this utility model discloses an anti-tipping device for a hydrogen storage and transportation device. The device includes a top plate 1, a left support frame 3, and a right support frame 4. The outer edges of the left support frame 3 and the right support frame 4 coincide with the bottom wide edge of the top plate 1 and are perpendicular to the top plate 1. The bottom of the left support frame 3 and the right support frame 4 are connected by a base plate 6. The base plate 6 consists of two L-shaped supports, which are welded to the opposite bottom legs of the left support frame 3 and the right support frame 4 to stabilize them. The sum of the length of the base plate 6 and the width of the left support frame 3 and the right support frame 4 is equal to the length of the top plate 1. The right support frame 4 has the same structure, with its sides shaped like isosceles triangles. This isosceles triangle design ensures the stability of the device. A horizontal bar 5, parallel to the bottom length of the left support frame 3 and the right support frame 4, runs along the isosceles triangle. The horizontal bar 5 increases the overall load-bearing capacity of the support frame and prevents deformation when the device falls, thus ensuring its service life. The top plate 1, bottom plate 6, left support frame 3, and right support frame 4 are all welded together to form a unified structure, ensuring the reliability of the device. The width of the top plate 1 is twice the width of the left support frames 3. Compared to conventional supports, the top plate 1 of this application is a rectangular plate with a wider contact surface with the hydrogen storage and transportation device, making it easier to distribute pressure and ensure stability. Numerous protrusions and recesses are provided on the top plate 1 to increase friction with the hydrogen storage and transportation device, ensuring the stability of the support.

[0016] A handle 2 is located in the middle of the long side of the top plate 1. The handle 2 is U-shaped, with a length of 1 / 2 the length of the top plate 1, a width of 7 / 5 the width of the top plate 1, and a height of 2 / 5 the height of the top plate 1. The wide U-shaped handle 2 is designed to accommodate the different fist widths of various people. Both turning points of the U-shape are designed to be curved to avoid hand injury during movement and to facilitate the movement of this device. The left support frame 3, right support frame 4, and handle 2 are all located on the same side, and are equipped with casters 7. The casters 7 are fixed to the lower part of the side by welding or bolts, and the distance between the casters 7 and the ground is 1 / 2 the height of the base plate 6. This ensures that when stationary, the casters 7 will not contact the ground and compromise the stability of this application. When movement is required, pulling the handle 2 will tilt the device to one side of the handle 2, causing the casters 7 to contact the ground and move the device, saving on transportation costs and making operation more convenient.

[0017] The width of the top plate 1 is 1 / 10 of the length of the left support frame 3 and the right support frame 4. To ensure that the device can transmit pressure to the bottom surface after bearing pressure, and considering the ground's bearing capacity, the 1 / 10 length difference, i.e., the isosceles triangle, forms a near-right acute triangle. This ensures full contact between the bottom and the ground, bearing pressure while avoiding an excessively large angle. Otherwise, gently pulling the handle 2 would not achieve the desired tilting effect, and the casters 7 would not make contact with the ground, making movement inconvenient and failing to achieve the expected time-saving and labor-saving effect. The width of the crossbar 5 is the same as the width of the left support frame 3 and the right support frame 4, with a length ratio of 2:3. The height and width of the crossbar 5 are the same. The width of the bottom plate 6 is the same as the width of the crossbar 5, and the height of the top plate 1 is 1 / 2 the width of the top plate 1.

[0018] Specific implementation principle: When using this utility model, the device can first be manually tilted and placed under the chassis of the hydrogen storage and transportation device semi-trailer. The bottoms of the left support frame 3 and right support frame 4 are then aligned and fully in contact with the ground. The casters 7 are positioned away from the ground for support. The pressure of the hydrogen storage and transportation device acts on the top plate 1. Since the contact area between the top plate 1 and the hydrogen storage and transportation device is large, the force is dispersed and then applied to the bottom plate 6. When the device is not needed, the worker only needs to pull the handle 2 to move the support frame. The entire process requires no manual adjustment or fixing of the device. It is simple to operate, highly stable and flexible. Customized services can be provided for hydrogen storage and transportation devices of different heights. The operation is simple and the cost is low. The above describes the entire working process of the device. Any content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0019] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
