Coal mine underground explosion proof rubber tire transport trolley

Abstract

The invention relate to a coal mine underground explosion proof rubber tire transport trolley, the primary structure of which comprises a self-discharging carriage, a cab, front and back wheels, a frame, a spring suspension fork, a transfer case, front and back driving axles, a explosion proof diesel motor, a waste gas treatment box, a water supplementing tank, a gas tank, a power accumulator, an explosion proof protector, a hydraulic mechanism, and a pneumatic mechanism and adopts the integrate frame; wherein the front and back wheels are provided with a spring suspension fork, are driven by time-sharing four-wheel and steered with the front wheels; a disk type braking is used; explosion proof protection uses the sensor information technique, mechanical variable speed, hydraulic transmission, and air-powered braking; the rubber tire transport trolley has the advantages of reasonable design, compact structure, small volume, strong grade ability, small turning radius, is flexible, safe, stable and reliable, is very suitable for working in coal mine underground severe atmosphere, is an ideal coal mine underground explosion proof rubber tire transport trolley, and also can assist to transport in other ores.

Description

technical field [0001] The invention relates to an explosion-proof rubber-tyred transport vehicle underground in coal mines, belonging to the technical field of design and manufacture of auxiliary transport equipment in underground coal mines. Background technique [0002] The underground coal mine is a narrow working space with harsh environment. Coal mining, roadway support, coal transportation, equipment installation, and auxiliary material transportation are all completed in this small space, which brings great difficulties to coal mining operations and safe transportation. The auxiliary transportation in the roadway is more difficult. The uneven ground, difficult turning, frequent transportation, large transportation volume, many varieties, low efficiency and high failure rate have always been a technical problem. [0003] At present, there are some small auxiliary transport vehicles deployed underground in coal mines, but due to deficiencies in the design structure, su...

Problems solved by technology

[0002] The underground coal mine is a narrow working space with harsh environment. Coal mining, roadway support, coal transportation, equipment installation, and auxiliary material transportation are all completed in this small space, which brings great difficulties to coal mining operations and safe transportation. The auxiliary transportation in the roadway is more difficult, the ground is uneven, the steering is difficult, the transportation is frequent, the transportation volume is large, the variety is large, the efficiency is low, and the failure rate is high, which has always been a technical problem

[0003] At present, there are some small auxiliary transport vehicles deployed underground in coal mines, but due to deficiencies in the design structure, such as poor explosion-proof performance, insufficient suspension ride comfort, front and rear wheels cannot be driven in time-sharing, the steering radius is too large, emergency braking, parking, braking Unreliable movement, which greatly restricts the underground auxiliary transportation of coal mines, resulting in low efficiency of underground transportation and many potential safety hazards
