Tuyere remover
A component of a gas injection system (tuyere/tymp) removal apparatus comprising a pneumatic or hydraulic hammer reverse mounted into a hammer frame, the working end of the hammer fixedly attached a first end of a slidable frame. The slidable frame having a second end fixedly attached to an elongated lifting arm means with a component handling means, and two sides slidably attached to the hammer frame. The component handling means may be inserted into the rear of a component of a gas injection system. When activated, the hammer generates a pulling motion on the component handling means engaged with the component of a gas injection system, releasing the component of a gas injection system from the wall of the blast furnace.
1. An apparatus mountable on a self-propelled vehicle for handling, installing and/or removing a tuyere or tymp from a shaft furnace, consisting essentially of:
a movable frame having first and second ends and an engagement component mounted on the second end of the movable frame for engaging the tuyere or tymp; wherein the movable frame consists essentially of a one-piece construction and is mounted on a second frame so that the movable frame can move in at least first and second directions;
a hammer mounted on the second frame wherein a longitudinal axis of the hammer is co-linear with a longitudinal axis of the second frame and wherein a working end of the hammer acts against the movable frame to move the movable frame in a first direction.
2. The apparatus of claim 1 wherein the hammer consists essentially of a hydraulic-powered hammer.
3. The apparatus of claim 1 wherein the hammer consists essentially of a pneumatic-powered hammer.
4. The apparatus of claim 1 wherein the hammer consists essentially of a power hammer.
5. The apparatus of claim 1 wherein the hammer consists essentially of an electric-powered hammer.
6. The apparatus of claim 1 wherein the engagement component is a hook.
7. The apparatus of claim 1 wherein the engagement component is integral with the movable frame.
