Description

Technical Field

[0001] The utility model relates to the field of nitrogen tank conveying devices, in particular to a protective device for nitrogen transportation. Background Art

[0002] The chemical properties of nitrogen are very stable, and it generally does not react with other substances. This inert quality makes it widely used in many anaerobic environments to play the role of isolation, flame retardancy, explosion-proof, and anti-corrosion. Nitrogen can also be used as a covering gas in the packaging of processed foods and medicines, sealing cables and telephone lines, and pressurizing expandable rubber tires. Due to its wide application, the demand for the production and preparation of nitrogen is relatively high. After production, it is filled and transported to various use terminals. During the transportation process, the nitrogen tank will have certain friction and collision due to the left and right swing of the conveyor vehicle due to acceleration and braking. Even if it is fixed by a mechanical frame, damage will still exist. The patent with application number 202223227473.4 introduces a protective device for nitrogen transportation, which uses multiple springs to protect against bumps in transportation, but simple springs will increase the frequency of vibration and the protective effect is limited.

[0017] The utility model is further described below in conjunction with the accompanying drawings:

[0018] like Figure 1-4 As shown, a nitrogen transport protection device is composed of a plurality of square protection frames 1 assembled together, and the plurality of square protection frames 1 are assembled and connected together by an assembly plug-in 7;

[0019] A damping protection telescopic column 2 is fixedly installed on the inner frame edge of the square protection frame 1, one is set on each frame edge, and each square protection frame 1 is provided with four damping protection telescopic columns 2. The ends of the damping protection telescopic columns 2 are connected and installed with arc-shaped pressing pieces 3. The four arc-shaped pressing pieces 3 sandwich the nitrogen tank 4 in the middle, so as to protect it during transportation;

[0020] The damping protection telescopic column 2 is composed of a damping protection column 13 and a column cavity shell 14. A column cavity is provided in the column cavity shell 14. A damping plug 16 is provided in the sliding plug in the column cavity. Compression springs 15 are provided in the column cavity on both sides of the damping plug 16. One end of the damping protection column 13 extends into the column cavity and is connected and installed on the damping plug 16. Damping air holes 17 are provided on the upper and lower sides of the side cavity wall of the column cavity.

[0021] An assembling hole 8 is provided on the frame body of the square protection frame 1 , and both ends of the assembling plug-in 7 are inserted and installed in the assembling hole 8 .

[0022] like Figure 1-Figure 4 As shown, the utility model also discloses the following more optimized specific structures:

[0023] The assembly plug-in 7 is provided with a plug-in limiting hole 18, and the square protection frame 1 is provided with an assembly spring pin 12, and the bottom end of the assembly spring pin 12 is inserted into the plug-in limiting hole 18 to achieve limited assembly, and the top end of the assembly spring pin 12 extends to the top of the square protection frame 1 and is installed with a plug-in cap 5;

[0024] A rebound pin cavity 9 is provided on the square protective frame 1 above the assembly hole 8, and a pin limiting ear 11 is provided on the assembly elastic column pin 12 in the rebound pin cavity 9. A pin sleeve spring 10 is sleeved on the assembly elastic column pin 12 on the pin limiting ear 11 to facilitate rebound.

[0025] An inner arc pad 6 is attached and installed on the inner arc surface of the arc-shaped pressing piece 3 to facilitate protection of the outer wall of the nitrogen tank 4.

[0026] One-way plug-in slopes 19 are provided at both ends of the assembly plug-in 7, which are designed to be sloped so that when two square protective frames 1 are assembled, they press the assembly spring pin 12, and then the assembly spring pin 12 is inserted into the plug-in limit hole 18 under the action of the pin sleeve spring 10.

[0027] like Figure 1-Figure 4The protective device for nitrogen transportation shown is sleeved on the nitrogen tank 4, and the arc-shaped pressing piece 3 is pressed onto the outer wall of the nitrogen tank 4 through the inner arc pad 6 for protection. When loading, two adjacent square protective frames 1 are assembled together by assembling plugs 7, and limited by assembling spring pins 12, so that several nitrogen tanks 4 on the transport vehicle are assembled together. When accelerating, braking or shaking left and right during transportation, the nitrogen tank 4 presses the arc-shaped pressing piece 3, so that the damping plug 16 presses the spring to move, and at the same time the air pressure in the cavity changes, so that the air flow enters and is discharged from the two damping air holes 17. Due to the limited aperture, it cannot be discharged quickly, and there is a buffer time, which realizes overall shock absorption protection while providing damping protection.
