Abstract

The invention relates to a stone stripping expanding fixture. The fixture consists of side blocks, a shaft pin and a steel wedge, wherein each side block has a semi-cylindrical structure; one end of the structure is provided with an inclined surface, and the other end of the structure is provided with an end handle; the side blocks are arranged oppositely; the shaft pin passes through and connects the end handles of the side blocks; the whole structure is cylindrical; the top of one side block is fixedly provided with a steel wire rope with appropriate length; and the steel wedge has a wedge structure. The expanding fixture is cylindrical, and is suitable to be arranged in a drilled hole with the corresponding hole diameter, the position of the expanding fixture in the drilled hole is adjusted by the steel wire rope, and the steel wedge expands the side blocks along the inclined surfaces between the side blocks by applying pressure to the steel wedge so as to fulfill the aim of expanding the side blocks; and stones can be stripped from a bed body under the combined action of a plurality of expanding fixtures. The expanding fixture has the advantages of simple structure, low cost and good using effect.

Description
