Drawings
Fig. 1 is a schematic structural view of a furnace hearth refractory brick replacing tool of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the following detailed description and accompanying drawings.
As shown in fig. 1, a hearth refractory brick replacement tool includes: the three upright pull rods 1 which are arranged in a triangular shape and the lifting seat 2 are fixed at the upper ends of the three pull rods 1 respectively with the lower part of the lifting seat 2, the upper part of the lifting seat 2 is provided with a lifting ring 3, the three pull rods 1 are inclined outwards from top to bottom, the lower ends of the three pull rods 1 can be opened outwards, the three pull rods 1 can be elastically deformed and drawn inwards under the action of external force, and the lower ends of the three pull rods 1 are respectively provided with a draw hook 4 which is arranged outwards.
In this embodiment, a sliding sleeve 5 is sleeved on the three pull rods 1, and the sliding sleeve 5 can hoop the three pull rods 1 after sliding downwards under the action of external force, so that the lower ends of the three pull rods 1 can drive the drag hooks 4 to move inwards.
A return spring 6 is arranged between the sliding sleeve 5 and the lifting seat 2, one end of the return spring 6 is connected with the sliding sleeve 5, and the other end of the return spring 6 is connected with the lifting seat 2.
The upper ends of the three pull rods 1 are respectively in threaded connection with the lifting seat 2, and the arrangement is convenient for replacing the pull rods 1. The three draw hooks 4 are respectively in threaded connection with the draw rod 1, and the arrangement is convenient for replacing the draw hooks 4. The inner edges of the upper end and the lower end of the sliding sleeve 5 are chamfered, so that the pull rod 1 and the sliding sleeve 5 are prevented from being excessively worn. Anti-skidding salient points are arranged on the outer side of the sliding sleeve 5.
The change instrument mainly be in order to cooperate a novel firebrick of stove platform to use, novel firebrick of stove platform's structure includes: the brick comprises a square brick body, wherein a small round hole is formed in the upper surface of the brick body, a large round hole is formed in the lower surface of the brick body, and the small round hole and the large round hole are coaxial and communicated.
When the tool is in operation, a worker carries the tool to be replaced and holds the sliding sleeve 5, and then drives the sliding sleeve 5 to slide downwards, so that the three draw hooks 4 are drawn close inwards; then the three draw hooks 4 downwards pass through the small round holes on the brick body until the three draw hooks 4 reach the large round holes; then the worker loosens the sliding sleeve 5, so that the sliding sleeve 5 is reset upwards under the action of the reset spring 6, the three draw hooks 4 are opened outwards and can be hooked on the bottom of the large round hole, and the worker can lift up the refractory bricks to be replaced through a replacing tool.
