Abstract
The utility model discloses an auxiliary device used for measuring explosion speed of emulsion explosive in a blast hole. The lower end of a fixed wire is fixed on the upper part of the target wire board. A weight is suspended below the lower part of the target wire board through a pull line. A lead is composed of four thin leads. Tail ends of the four thin leads are connected with an enameling copper wire each. Two of the enameling copper wires are clamped in an upper target wire groove after being twisted with other and the tail ends of said enameling copper wires are wrapped with waterproof rubberized fabric. The other two of the enameling copper wires are clamped in a lower target wire groove after being twisted with each other and the tail ends of said enameling copper wires are wrapped with waterproof rubberized fabric. Heat produced in an explosion process enables the enameling copper wires and the corresponding thin leads in the lower part and in the upper part to enter a connecting state successively. The explosion speed of the emulsion explosive in the blast hole can be obtained through calculating the distance between the upper target wire groove and the lower target wire groove and the time difference referred to connecting signals. Therefore, a defect that the explosion speed in the blast hole cannot be measured accurately by adopting an electrometric method and a detonating fuse method is made up. Moreover, since the auxiliary device adopts common components having low prices, the manufacturing cost of the auxiliary device is comparatively low.
