Abstract
The utility model discloses an internal cooling system for hot assembly of an aluminum alloy drill rod and a connector. The internal cooling system is composed of an internal circulation seal, a double-wall drill rod joint, a fixed double-wall mandrel, a faucet core pipe joint and a double-channel faucet. According to the internal cooling system, the side face of the double-channel faucet is a water inlet, the end of the double-channel faucet is a cooling liquid discharge port, and two channels do not interfere with each other. An annular channel composed of an outer pipe and an inner pipe of the fixed double-wall mandrel is a cooling liquid inlet channel. An inner cavity of the inner pipe is a cooling liquid discharge channel. The double-channel faucet, the fixed double-wall mandrel and the internal circulation seal are connected through a double-channel connection joint. A long pipeline is divided into several short sections so that the steel connector to be connected with the aluminum alloy drill rod can be placed, assembled, disassembled and replaced conveniently. Cooling liquid flows in a circulating mode to cool the assembly part of the drill rod, so that the temperature of the drill rod does not exceed the maximum allowable service temperature of an aluminum alloy, and therefore the situation that an overtemperature causes a microcosmic crystal structure in the aluminum alloy to change, so that the using performance of the aluminum alloy is influenced is prevented.
