Description

Technical Field

[0001] The utility model relates to the technical field of hydrogen production and transportation, in particular to a buffer mechanism for hydrogen storage tank transportation. Background Art

[0002] Hydrogen is the lightest gas known in the world. Its density is very small, only 1 / 14 of air, that is, at standard atmospheric pressure and 0°C, the density of hydrogen is 0.0899g / L. Therefore, hydrogen can be used as the filling gas of airships. Hydrogen is mainly used as a reducing agent. After purification, hydrogen needs to be canned and transported. Most of the existing hydrogen tank transportation technologies use trolleys to transport them, but some existing trolleys do not have anti-vibration buffer mechanisms. If a trolley loaded with a hydrogen tank vibrates significantly during movement, it will also cause certain damage to the hydrogen tank, resulting in hydrogen leakage, which poses a greater safety hazard. Utility Model Content

[0003] In view of this, the utility model provides a buffer mechanism for transporting hydrogen storage tanks, which can provide earthquake-resistant protection for the hydrogen tanks through the buffering of the transverse damping rod and the shock absorption of the longitudinal spring. In the event of vibration, the hydrogen tanks can be buffered and shock-absorbed to prevent damage to the hydrogen tanks, and the safety is high.

When the staff pushes the trolley body to move, if there is a collision in the front, the guide column slides in the transverse buffer groove, and the guide column compresses the transverse damping rod and the transverse spring at the same time. The output end of the transverse damping rod is recovered to buffer the sliding force of the guide column, so that the speed of the guide column gradually slows down to stop when sliding, and then the rebound force of the transverse spring drives the output end of the transverse damping rod to extend and reset. The inertial movement of the guide column and the tank body is buffered by the cooperation of the transverse damping rod and the transverse spring. When the trolley body passes through the groove or protrusion on the bottom surface, the movable column drives the tank body to move upward or downward, and at the same time, the connecting blocks on both sides of the movable column compress or stretch the longitudinal spring. The longitudinal spring is used to shock-absorb and buffer the connecting blocks and the movable column, and then the tank body can be shock-absorbed and buffered. Through the cooperation of the transverse buffer groove and the longitudinal buffer groove, the hydrogen tank can be seismically protected, and the hydrogen tank can be buffered and shock-absorbed in the event of vibration to prevent damage to the hydrogen tank, with high safety.

[0005] The cross section of the clamping plate is arc-shaped, and the arc-shaped clamping plate improves the clamping effect on the tank body.

[0007] A through hole is provided in the center of the connecting block, and a guide rod is arranged through the through hole of the connecting block. The cross section of the guide rod is matched with the cross section of the through hole of the connecting block. The upper end of the guide rod is fixed to the upper inner wall of the longitudinal buffer groove, and the lower end of the guide rod passes through the center of the longitudinal spring and is fixed to the lower inner wall of the longitudinal buffer groove. When the connecting block moves up or down, it can slide along the length direction of the guide rod.

The staff can place the tank body on the support plate and start the telescopic push rod to make the splint clamp the tank body. When shaking occurs, the support plate drives the support column and the fixed column to move downward, and the fixed column drives the telescopic rod to compress the buffer spring, so that the support plate can support the bottom of the tank body and improve the stability of the tank body.

[0009] In summary, compared with the prior art, the present application includes at least one of the following beneficial technical effects:

[0010] 1. When the utility model is used, the staff places the tank body between the two clamping plates, and then starts the telescopic push rod. The output end of the telescopic push rod drives the clamping plate to move in the direction of the tank body, so that the clamping plate clamps and fixes the tank body. When the staff pushes the cart body to move, if there is a collision in the front, the guide column slides in the transverse buffer groove, and at the same time, the guide column compresses the transverse damping rod and the transverse spring. The output end of the transverse damping rod is recovered to buffer the sliding force of the guide column, so that the speed of the guide column gradually slows down to a stop when sliding, and then the rebound force of the transverse spring drives the output of the transverse damping rod The end is extended and reset, and the inertial movement of the guide column and the tank body is buffered by the cooperation of the transverse damping rod and the transverse spring. When the cart body passes through the groove or protrusion on the bottom surface, the movable column drives the tank body to move up or down. At the same time, the connecting blocks on both sides of the movable column compress or stretch the longitudinal spring. The longitudinal spring is used to shock-absorb the connecting blocks and the movable column, and then the tank body can be shock-absorbed and buffered. Through the cooperation of the transverse buffer groove and the longitudinal buffer groove, the hydrogen tank can be protected from earthquakes. In the event of vibration, the hydrogen tank can be buffered and shock-absorbed to prevent damage to the hydrogen tank, with high safety.

A tank body 200 is clamped between the two clamping plates 407. The staff places the tank body 200 between the two clamping plates 407, and then starts the telescopic push rod 406. The output end of the telescopic push rod 406 drives the clamping plate 407 to move toward the tank body 200, thereby causing the clamping plate 407 to clamp the tank body 200. The guide column 301 is clamped and fixed. When the staff pushes the cart body 100 to move, if there is a collision in the front, the guide column 301 slides in the transverse buffer groove 300. At the same time, the guide column 301 compresses the transverse damping rod 302 and the transverse spring 304. The output end of the transverse damping rod 302 is recovered to buffer the sliding force of the guide column 301, so that the speed of the guide column 301 gradually slows down to stop when sliding.
