Hoisting tool capable of facilitating mounting and preventing damage of sand core

Abstract

The invention discloses a hoisting tool capable of facilitating mounting and preventing damage of a sand core. The hoisting tool comprises the sand core, and two arbors are arranged in the sand core;the top ends of the arbors vertically stretch out of the top of the sand core; the two arbors are symmetrical about the vertical axis of the sand core; threaded holes are formed in the top ends of thearbors; hooks are mounted in the threaded holes; the arbors are of an inverted-T-shaped structure; horizontal rod parts of the inverted-T-shaped structures of the arbors are positioned in the sand core; and vertical rod parts of the inverted-T-shaped structure of the arbors upwards stretch out of the top of the sand core. According to the hoisting tool, hoisting is achieved by mounting the arborsof the simple structure in the sand core, the sand core does not need to be externally clamped during the mounting process, and the external part of the sand core is not damaged; and besides, the arbors and the hooks can be disassembled, so that the size can be decreased, and the integral hoisting tool is prevented from being affected when the hooks are damaged.

Description

technical field [0001] The invention relates to the technical field of large-scale sand core installation, in particular to a hoisting tool which is convenient for installation and does not damage the sand core. Background technique [0002] In sand core casting, a large sand core is needed, but there is no fixed place outside the sand core for transport, and ordinary transport may cause damage to the sand core during transport. [0003] Chinese patent (CN 202606802 U) provides a "casting sand core sling", which can be used to easily clamp the sand core outside for transportation, but the sand core will eventually be put into the mold. At this time, such a clamping The tooling cannot be installed normally. In response to this situation, someone invented "a large-scale casting air cavity sand core core bone" (CN 106670395 A), but this core bone structure is relatively complicated, and it takes up a large volume when hoisting, and the hook cannot be disassembled. Damage to t...

[0002] In sand core casting, a large sand core is required, but there is no place outside the sand core for fixed handling, and ordinary handling may cause damage to the sand core during handling

[0003] Chinese patent (CN 202606802 U) provides a "casting sand core sling", which can be used to easily clamp the sand core outside for transportation, but the sand core will eventually be put into the mold. At this time, such a clamping Tooling cannot be installed normally

In response to this situation, someone invented "a large-scale casting air cavity sand core core" (CN 106670395 A), but this core structure is relatively complicated, and it takes up a large volume when hoisting, and the hook cannot be disassembled. Damage to the hook will lead to core bone failure
