Abstract

The utility model provides an explosion-proof stranded wire cutting saw. A completely sealed chamber body comprises a tongs block, a tongs block seal box, a saw blade seal box, a saw blade seal box cover, a seal gasket, a tongs block seal box screwed plug and the like. The opening of the tongs block seal box can be inserted in and oppositely joined with the opening of the saw blade seal box, which can slide relative to the opening of the saw blade seal box. Water is injected into the sealed chamber from the center hole of a worm shaft. A saw blade cuts stranded wires completely in water. Water not only plays a role in cooling and lubrication so that the cutting force is reduced and the service life of a cutter is improved, but also isolates the points being cut from outside air to achieve the optimum explosion-proof effect. The explosion-proof stranded wire cutting saw cuts off the stranded wires or anchor rods by cutting, and can directly use a requisite drill underground as a power source. A cutter adopting the pure principle of machinery is highly reliable, and is free from the environmental limit, which is suitable to be used under poor working conditions; the manufacturing cost and the maintenance cost are relatively low; and the service life is long.
