Description

Technical Field

[0001] The utility model relates to the technical field of vehicle gas cylinders, in particular to an airtight device for a gas cylinder of a wheeled armored vehicle. Background Art

[0002] In daily life, large motor vehicles always make a sound of gas overflowing when driving and parking, which often confuses people. In fact, this sound occurs because large motor vehicles use gas brakes to control the braking state of the vehicle. These gases are provided by the vehicle's own air compressor and are usually stored in gas cylinders under the vehicle chassis. When in use, they are transported to the inside of the brake mechanism through gas pipelines to control the braking state of the vehicle.

[0003] However, due to the large number of pipelines in the existing vehicles, even if one pipeline is damaged, the gas in the gas cylinder will leak out from the damaged part of the pipeline, resulting in the need to refill the gas cylinder when starting the vehicle next time, delaying daily vehicle operations and restricting driving efficiency. In addition, large vehicles often transport a large amount of goods on urban roads due to their high transport load capacity. In the face of complex road conditions and to ensure their own transportation safety, they often take emergency braking measures in advance. This may cause the gas cylinder body to loosen its connection with the vehicle body due to its large inertia during emergency braking, resulting in a collision, which is prone to safety hazards. Therefore, we propose an airtight device for gas cylinders of wheeled armored vehicles to solve the above problems. Utility Model Content

At the same time, the gas cylinder can be well protected, solving the problem that a large amount of gas leakage may occur due to the direct connection between the existing gas cylinder and the pipeline, and the problem that the gas cylinder may easily have safety hazards during emergency braking.

[0014] Beneficial Effects

[0015] Compared with the prior art, the utility model provides a gas sealing device for a gas cylinder of a wheeled armored vehicle, which has the following beneficial effects:

[0016] 1.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-4A gas cylinder airtight device for a wheeled armored vehicle comprises a plurality of gas cylinder bodies 1 and a vehicle chassis 7. The number of gas cylinder bodies 1 is four, and the shapes and sizes are the same. All gas cylinder bodies 1 are parallel and equidistantly distributed on the vehicle chassis 7. Gas pipelines 4 are fixedly connected between adjacent gas cylinder bodies 1. Solenoid valves 2 are fixedly installed on the inlet and outlet ends of the gas cylinder bodies 1, respectively. A pipeline adapter 3 is fixedly connected to the outside of the solenoid valve 2. A gas pipeline 4 is fixedly connected to the outside of the pipeline adapter 3. The gas pipeline 4 is fixedly connected to the gas cylinder body 1 through the solenoid valve 2. The gas cylinder body 1, the solenoid valve 2, the pipeline adapter 3, and the gas pipeline 4 are interconnected.

[0025] The surface of the solenoid valve 2 is fixedly connected to the wire 5, one end of the wire 5 is fixedly connected to the starting switch 6, the starting switch 6 is electrically connected to the solenoid valve 2, the starting switch 6 is the key switch of the wheeled armored vehicle, so the switch of the solenoid valve 2 is determined by the working state of the vehicle, the bottom of the vehicle chassis 7 is fixedly connected to the fixing plate 8, the fixing plate 8 is fixed to the vehicle chassis 7 by a nut, the outer surface of the fixing plate 8 is provided with a spring 9, the number of groups of the fixing plate 8, the buffer plate 11 and the spring 9 are two groups respectively, and they are symmetrically distributed at the inlet and outlet ends of the gas cylinder body 1, the surface of the buffer plate 11 fits with the two ends of the gas cylinder body 1, and the buffer plate 11 is in contact with the gas cylinder body 1.

[0026] The outer surface of the fixed plate 8 is fixedly connected to a sliding rod 10, and the outer surface of the sliding rod 10 is slidably connected to a buffer plate 11. There are four sliding rods 10, and the sliding rods 10 are of the same size and are symmetrically distributed on the surface of the fixed plate 8 in a rectangular shape. The spring 9 is sleeved on the outer surface of the sliding rod 10, and the two ends are respectively fixedly connected to the fixed plate 8 and the buffer plate 11. The number of springs 9 is the same as that of the sliding rod 10. Holes 12 are provided on the surfaces of the fixed plate 8 and the buffer plate 11. The size and shape of the holes 12 are the same. The solenoid valve 2 is divided into an electromagnetic control part and an external pipeline part. The hole 12 matches the size of the pipeline part on the solenoid valve 2.

[0027] To sum up, when the armored vehicle is started, the starting switch 6 is turned on, so that the solenoid valve 2 is opened, and the opening of the solenoid valve 2 makes the gas cylinder body 1 connected with the gas pipeline 4, so that the gas can enter the braking system of the armored vehicle, so that the vehicle can maintain a normal braking state; when the armored vehicle is shut down, the starting switch 6 is turned off, so that the solenoid valve 2 is closed, and the closing of the solenoid valve 2 makes it impossible for the gas cylinder body 1 to be connected with the gas pipeline 4, cutting off the direct connection between the gas cylinder body 1 and the gas pipeline 4, so that when a leak occurs somewhere in the gas pipeline 4, it will not affect the sealed gas cylinder body 1, avoiding the situation that the internal gas of the gas cylinder body 1 leaks when a local leak occurs in the vehicle gas pipeline 4, and solving the problem that the existing gas cylinder body 1 is in direct contact with the gas pipeline, resulting in the inability to retain gas inside the gas cylinder body 1, so that the gas cylinder body 1 needs to be re-inflated when the vehicle is started, causing delays in leaving the vehicle and restricting driving efficiency.

[0028] When the vehicle performs emergency braking, under the action of large inertia, the gas cylinder body 1 will be displaced to a certain extent, and at this time, a certain squeezing force will be generated on the buffer plate 11, causing the buffer plate 11 to move along the sliding rod 10 toward the fixed plate 8, and the spring 9 between the two is squeezed. Under the reaction of the elastic force of the spring 9, the gas cylinder body 1 is buffered, offsetting the influence of inertia on the gas cylinder during vehicle braking, and no collision will occur due to loose connection with the vehicle body due to large inertia, so that the safety and reliability of the gas cylinder body 1 for armored vehicle braking in actual use is greatly improved.
