Description

Technical Field

[0001] The utility model relates to the technical field of mine car gas path equipment, in particular to a mine car gas storage device. Background Art

[0002] The mine car's air reservoir is a key component in the vehicle's entire air system. Its core function is to store compressed air, which comes from a compressor. The compressor compresses the outside air through work and then presses it into the air reservoir. This stored compressed air is not idle; it is released as needed through the corresponding valves when the vehicle needs it, such as when the braking system is working or other related pneumatic components require power, thereby ensuring the normal operation of various parts of the vehicle. For example, when the driver steps on the brake pedal, the compressed air in the air reservoir will quickly flow through the brake line to the brake cylinder, pushing the brake shoe into contact with the brake drum, thereby generating braking force to slow down or stop the vehicle.

[0003] In actual operation, numerous factors can contribute to pressure overflow within the air reservoir. Leakage in the air system is inevitable. For example, gaps may develop in pipe connections due to prolonged vibration or aging seals, allowing compressed air to leak out and causing pressure to drop within the reservoir. Thermal expansion and contraction can also affect reservoir pressure. Significant changes in ambient temperature can alter the volume of air within the reservoir, potentially causing pressure overflow in some cases.

[0004] Once this pressure overflow occurs, the pressure in the air reservoir will be insufficient, affecting the proper functioning of the vehicle's braking system and other pneumatic components. In severe cases, it can even cause the vehicle to become inoperable, increasing the probability of failure and impacting the mine's transportation efficiency. Furthermore, when mining vehicles are used in rainy weather, the air compressed in the braking system contains a high amount of water, which can easily cause metal parts in the automatic system to rust and seals to rupture, making the braking system prone to problems.

[0026] The following is combined with Figure 1 -Attached Figure 4 The utility model is described in further detail.

[0027] The present utility model discloses a mine car gas storage device. Figure 1 The mine car air storage device includes a bracket 1, a compressor 2, an air storage cylinder 3, a one-way valve 4 and an air dryer 5. The compressor 2, the air storage cylinder 3, the one-way valve 4 and the air dryer 5 are integrated and installed in the bracket 1, and the bracket 1 is bolted to the bottom of the mine car frame to facilitate the assembly of various components and subsequent maintenance.

[0028] Reference Figure 1 and Figure 2The bracket 1 includes an outer frame 10 in the shape of a rectangular frame, and a middle frame 11 is welded in the middle of the outer frame 10. The middle frame 11 divides the internal space of the outer frame 10 into two independent installation areas, one of which is used to install the compressor 2 and the air dryer 5, and the other is used to install the air storage cylinder 3 and the one-way valve 4.

[0029] Reference Figure 1 、 Figure 2 and Figure 3 Four hangers 12 are fixed to the top of the outer frame 10. The tops of the hangers 12 are bolted to the mine car frame. Two bottom door rails 13 are hingedly mounted between the bottom of the outer frame 10 and the bottom of the middle frame 11. The hinges are installed between the bottom door rails 13 and the middle frame 11. A fixing plate 130 is fixed to the bottom door rails 13. The fixing plate 130 is movably mounted on the bottom of the outer frame 10 and fixed to the outer frame 10 by connecting screws 131.

[0030] Reference Figure 1 and Figure 4 A mounting bracket 14 is detachably mounted between the outer frame 10 and the middle frame 11. The mounting bracket 14 is used to secure the air dryer 5. U-shaped clamping plates 140 are welded to the four corners of the mounting bracket 14. The clamping plates 140 are clamped to the outer frame 10 or the middle frame 11, respectively. The clamping plates 140 are fixed to the outer frame 10 or the middle frame 11 by limiting members.
