Burning apparatus for railway repair

A burning apparatus for railway repair, defining an axis (P) and comprising:

• an air compressor assembly including an inlet opening and an outlet opening, and
• a combustion assembly connected to the outlet opening of the air compressor assembly,
• wherein the air compressor assembly and the combustion assembly are axially disposed along the axis (P), and wherein the air compressor assembly compresses air into the combustion assembly,
• wherein the air compressor assembly further comprises:
• a body axially disposed along the axis (P),
• a motor including a motor shaft and disposed in the body, and
• a propeller driven by the motor through the motor shaft and guiding air into the body,
• wherein the body comprises:
• an outer housing, and
• an inner housing disposed in the outer housing and connected to the outer housing, the motor disposed therein,
• wherein the inner housing and the outer housing define an air passage therebetween, and the propeller guides air from the air compressor assembly into the combustion assembly through the air passage;
• wherein the combustion assembly further includes a burning tube assembly disposed in the combustion assembly housing, the burning tube assembly comprising:
• an inlet disc,
• an outlet disc, and
• a burning tube body configured to be hollow and disposed along the axis (P) in the combustion assembly housing and between the inlet disc and the outlet disc,
• wherein the burning tube body and the combustion assembly housing define an air channel therebetween, and
• wherein the air passage of the air compressor assembly, the air channel of the combustion assembly, the burning tube body, and the outlet opening of the combustion assembly are designed to be communicated.

A preheating device for railway repair, comprising:

• a preheating device body, and
• a burning apparatus disposed in the preheating device, comprising:
• an air compressor assembly including an inlet opening and an outlet opening, and
• a combustion assembly connected to the outlet opening of the air compressor assembly,
• wherein the air compressor assembly and the combustion assembly are coaxially disposed, and wherein the air compressor assembly compresses air into the combustion assembly,
• wherein the air compressor assembly further comprises:
• a body,
• a motor including a motor shaft and disposed in the body, and
• a propeller driven by the motor through the motor shaft and guiding air into the body,
• wherein the body comprises:
• an outer housing, and
• an inner housing disposed in the outer housing and connected to the outer housing, the motor disposed therein,
• wherein the inner housing and the outer housing define an air passage therebetween, and the propeller guides air from the air compressor assembly into the combustion assembly through the air passage,
• wherein the preheating device is operated on a railway track to heat a railway.
