Description

Technical Field

[0001] This invention relates to the field of transportation, and in particular to a protective platform device for a liquid nitrogen tank. Background Technology

[0002] A dual-path sample introduction system for carbon and oxygen stable isotopes requires liquid nitrogen to facilitate better separation of substances with different isotopic compositions, thereby enabling more accurate measurement and analysis of the carbon and oxygen stable isotope ratios. Liquid nitrogen is an extremely cold liquid, and improper use can cause harm to personnel and equipment. Currently, laboratories use dedicated liquid nitrogen tanks, which need to be raised and maintained during use to ensure the liquid nitrogen is at a high level for better entry into the instrument. However, the liquid nitrogen tank is typically placed on a simple platform and raised, but this platform lacks stability during elevation, and combined with the tank's considerable weight, there is a risk of it tipping over. Summary of the Invention

[0003] To alleviate the problem of instability and potential tipping during the lifting of liquid nitrogen tanks, this invention provides a liquid nitrogen tank protection platform device.

[0004] This invention provides a liquid nitrogen tank protection platform device, which adopts the following technical solution:

[0005] A liquid nitrogen tank protection platform device includes a raising platform and a guardrail. The guardrail is disposed at the top of the raising platform. The raising platform includes a support platform, a lifting assembly, and a horizontal platform. The lifting assembly is disposed on the support platform. The horizontal platform is disposed at the movable end of the lifting assembly. The guardrail is disposed on the top surface of the horizontal platform.

[0006] By adopting the above technical solution, the guardrail can prevent the liquid nitrogen tank from tipping over and improve the stability of the liquid nitrogen tank during the lifting and lowering process.

[0007] In one specific implementation, the lifting assembly includes a first lifting element and a lifting platform. The first lifting element is disposed on the support platform, the lifting platform is disposed at the movable end of the first lifting element, and the horizontal platform is disposed on the lifting platform.

[0008] In one specific implementation, multiple first lifting elements are provided, and the multiple first lifting elements are distributed at intervals.

[0009] By adopting the above technical solution, multiple first lifting components can support the lifting platform from different directions, resulting in better support for the lifting platform, improved stability during the lifting process, and less likelihood of the liquid nitrogen tank tipping over.

[0010] In one specific implementation, a controller is provided on the bottom surface of the lifting platform, and a laser sensor is provided on the side wall of the controller.

[0011] By adopting the above technical solution, the laser sensor facilitates the measurement of the instrument height and the height of the horizontal platform, thereby facilitating the calculation of the height difference and enabling the automatic lifting and lowering of the first lifting element.

[0012] In one specific implementation scheme, the lifting platform is provided with a second lifting element, and the horizontal platform is located at the movable end of the second lifting element.

[0013] In one specific implementation, both the first lifting element and the second lifting element are electric push rods.

[0014] In one specific implementation, multiple second lifting elements are provided, and the multiple second lifting elements are distributed at intervals.

[0015] By adopting the above technical solution, multiple second lifting elements support the horizontal platform from different directions, improving the support effect. Each second lifting element can operate independently, facilitating the adjustment of the height of the horizontal platform in different directions and making it easier to level the platform.

[0016] In one specific implementation, a gyroscope is provided on the bottom surface of the horizontal platform.

[0017] By adopting the above technical solution, the real-time monitoring of the gyroscope makes it easier to understand the tilt direction and angle of the horizontal platform, making the leveling of the horizontal platform more targeted and improving the efficiency of leveling the horizontal platform.

[0018] In one specific implementation, the gyroscope is positioned at the center of the bottom surface of the horizontal platform.

[0019] In one specific feasible implementation, the height of the guardrail is greater than or equal to 50cm.

[0020] In one specific implementation, both the horizontal platform and the supporting platform are made of metal.

[0021] In one specific implementation, the guardrail is provided with a fixing strap.

[0022] In one specific implementation, the fixing strap is provided with a buckle.

[0023] By adopting the above technical solution, the fixing straps and buckles further secure the liquid nitrogen tank on the horizontal platform, reducing the shaking of the liquid nitrogen tank during lifting and transportation, and further improving the stability of the liquid nitrogen tank on the horizontal platform.

[0024] In one specific implementation scheme, the support platform is provided with multiple casters on its bottom surface.

[0025] By adopting the above technical solution, the installation of casters enables the liquid nitrogen tank protection platform device to have a transportation function, which can be used to transport liquid nitrogen tanks and improve the transportation efficiency of liquid nitrogen tanks.

[0026] In one specific implementation, the caster wheel has a brake.

[0027] In summary, the present invention has at least one of the following beneficial technical effects:

[0028] 1. Place the liquid nitrogen tank on a horizontal platform. The lifting assembly will lift the platform up and down. During the lifting process, the guardrail will support the liquid nitrogen tank. If the liquid nitrogen tank is to tip over, the guardrail will prevent it from doing so, thus improving the stability of the liquid nitrogen tank.

[0029] 2. The omnidirectional wheels enable the platform to move, allowing it to be used as a transport device for liquid nitrogen tanks, thus improving its applicability.

[0030] 3. The gyroscope can monitor whether the horizontal platform is level and adjust the platform accordingly, further improving the stability of the liquid nitrogen tank during lifting and lowering, making the liquid nitrogen tank less likely to tip over. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0037] Reference Figure 1 and Figure 2 The liquid nitrogen tank protection platform device includes a raised platform 2 and a guardrail 1. The raised platform 2 includes a support platform 21, a lifting assembly 22, and a horizontal platform 23. The lifting assembly 22 is mounted on the support platform 21, and the horizontal platform 23 is located at the movable end of the lifting assembly 22, allowing it to move up and down under the influence of the lifting assembly 22. The guardrail 1 is fixed to the top surface of the horizontal platform 23. When the liquid nitrogen tank is placed on the horizontal platform 23, and the horizontal platform 23 is raised or lowered by the lifting assembly 22, the liquid nitrogen tank rises and falls along with the horizontal platform 23.

[0038] Reference Figure 1 The support platform 21 is equipped with multiple casters 3, each with brakes 4, on its bottom surface, enabling it to move and serve as a transport vehicle for liquid nitrogen tanks. After the liquid nitrogen tanks are transported to their designated location, the brakes 4 stabilize the support platform 21. The casters 3 are made of PU (polyurethane) or rubber, providing good load-bearing capacity while remaining unaffected by minor ground undulations, thus enhancing stability during liquid nitrogen tank transport.

[0039] The protective railing 1 is a metal bar, specifically steel in this embodiment, but copper or other alloys may be used in other embodiments. The protective railing 1 is C-shaped when viewed from above, ensuring that the liquid nitrogen tank can only be placed on the horizontal platform 23 through the opening or above it. The protective railing 1 supports the liquid nitrogen tank on the horizontal platform 23, preventing it from tipping over during lifting. Even if the liquid nitrogen tank does tip over, the protective railing 1 reduces the magnitude of the tipping, ensuring the tank tilts rather than lies flat on the horizontal platform 23, effectively preventing injury from a tipping tank. The height of the protective railing 1 is greater than or equal to 50cm. Laboratory liquid nitrogen tanks are typically 50-70cm high; a 50cm high protective railing 1 minimizes the angle at which the tank tipps, preventing a rapid and large outflow of liquid nitrogen.

[0040] Reference Figure 1 The guardrail 1 is equipped with fixing straps 5. There can be one or more straps 5; in this embodiment, there are two. Each strap 5 has a locking buckle 6. After the liquid nitrogen tank is placed on the horizontal platform 23, the fixing straps 5 secure it, preventing swaying during transportation or lifting, greatly improving the stability of the liquid nitrogen tank. The locking buckles 6 allow for quick and easy securing of the straps 5 after they have secured the liquid nitrogen tank, improving the efficiency of the securing process. The fixing straps 5 are made of leather material, which has good tensile strength and is not easily broken, giving them a long service life.

[0041] Reference Figure 2The lifting assembly 22 includes a lifting platform 221 and multiple first lifting elements 222. The multiple first lifting elements 222 are spaced apart on the support platform 21. Each first lifting element 222 is a motorized push rod, and the lifting platform 221 is mounted on the piston rod of the motorized push rod. The first lifting elements 222 are distributed at the four corners of the lifting platform 221, and synchronously lift and lower the lifting platform 221, providing stable support for the lifting platform 221.

[0042] Reference Figure 2 The lifting platform 221 is equipped with multiple second lifting elements 7, each of which is an electric push rod. The horizontal platform 23 is mounted on the piston rod of the electric push rod. The second lifting elements 7 are distributed at the four corners of the horizontal platform 23. The second lifting elements 7 can lift and lower synchronously, driving the horizontal platform 23 to rise and fall, and providing stable support. Each second lifting element 7 can also operate independently, lifting and lowering the horizontal platform 23 in one direction. After the horizontal platform 23 is raised and lowered to the designated position, it is leveled, ensuring that the horizontal platform 23 remains horizontal. This also keeps the liquid nitrogen tank level when placed on the horizontal platform 23, making it less prone to tipping over.

[0043] Reference Figure 2 The first lifting element 222 and the second lifting element 7 are not limited to the electric push rod in this embodiment, but can also be elements such as hydraulic cylinders that can provide accurate lifting.

[0044] Reference Figure 3 A gyroscope 10 is installed on the bottom surface of the horizontal platform 23. The gyroscope 10 is specifically set at the center of the bottom surface of the horizontal platform 23 to monitor the tilt angle of the horizontal platform 23 in various directions in real time, so as to facilitate the leveling of the horizontal platform 23 by the second lifting element 7.

[0045] Reference Figure 4 A controller 8 is fixed to the bottom surface of the lifting platform 221, and a laser sensor 9 is installed on the side wall of the controller 8. The laser sensor 9, gyroscope 10, first lifting element 222, and second lifting element 7 are all communicatively connected to the controller 8. The laser sensor 9 measures the height of the instrument and the height of the horizontal platform 23, facilitating the controller 8 in calculating the height difference between the horizontal platform 23 and the instrument. In the experiment, the original requirement was to measure the height difference between the liquid nitrogen tank and the instrument; however, the accuracy requirement for the height difference was not high, and a reasonable range was sufficient. Therefore, the height of the horizontal platform 23, which is easier to measure, was used instead of the liquid nitrogen tank height.

[0046] Reference Figure 4After the controller 8 obtains the height difference, it can control the first lifting element 222 to adjust the height of the horizontal platform 23, thereby automatically controlling the height of the liquid nitrogen tank. After the liquid nitrogen tank reaches the designated height, the controller 8 obtains the data monitored by the gyroscope 10 to determine whether the horizontal platform 23 is level. If it is not level, it sends an electrical signal to the second lifting element 7 based on the data output by the gyroscope 10 to control the second lifting element 7 to operate and automatically level the horizontal platform 23.

[0047] The horizontal platform 23, lifting platform 221, and support platform 21 are all made of metal plates 50cm long, 50cm wide, and 0.3cm thick; in this embodiment, steel plates are specifically used. They are capable of bearing weights of 100kg or more. The dimensions of the horizontal platform 23, lifting platform 221, and support platform 21 can be adjusted according to requirements. The horizontal platform 23, lifting platform 221, and support platform 21 possess good load-bearing capacity and resistance to deformation, effectively extending the service life of the liquid nitrogen tank protection platform device.

[0048] The implementation principle of this invention is as follows: Lock the brake 4 of the universal wheel 3, place the liquid nitrogen tank through the opening in the guardrail 1 onto the horizontal platform 23, unlock the brake 4, move the liquid nitrogen tank to the designated location, and then lock the brake 4 again. The piston rod of the first lifting element 222 extends, causing the liquid nitrogen tank to rise to the designated height. The gyroscope 10 detects the horizontal platform 23, and based on the detection result of the gyroscope 10, sends an electrical signal to the second lifting element 7 through the controller 8. The second lifting element 7 then operates, automatically leveling the horizontal platform 23.

[0049] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
