Self-clamping equipment for rock core drilling

Abstract

The invention relates to the technical field of drill tool clamps, in particular to self-clamping equipment for rock core drilling. The equipment comprises a chute I and a chuck II, wherein a clamping surface of the chuck I is arc-shaped or V-shaped, a clamping surface of the chuck II is arc-shaped or V-shaped corresponding to the chuck I, and a lower part of the clamping surface of the chuck II is arranged of a slope protruding gradually from top to bottom; the chuck I is fixedly connected to a force bearing plate I fixedly arranged, the idle of the chuck II is in hinged connection to a force bearing plate II movably arranged, the force bearing plate II is connected to a translational driving mechanism which is used for driving the force bearing plate II to be close to or far away from the force bearing plate I. The equipment can ensure precise and vertical ram material rock core and quick loading. The chuck II generates a holding force automatically under the gravity of the ram material rock core and the pressure of drill bit. After the drill bit is lifted up, the holding force of the drill bit is removed not manually. After core drilling, it is not needed to clean the two chucks, so that the loading time is shortened and the rock core drilling work efficiency can be improved greatly by using the equipment.

Description

technical field [0001] The invention relates to the technical field of drilling fixtures, in particular to a core drilling self-clamping device. Background technique [0002] At present, the core drilling work is to use the raw material core (the core diameter is usually greater than 50mm), saw and cut it into a cylinder greater than 100mm, and then clamp it vertically with a manual straight clamp. When clamping, it is necessary to manually shake the handle; adjust the rocker drill, After making the drill bit concentric with the raw material core, turn on the cooling water to drill. After drilling, shake the clamp handle to release the clamping state, lift the drill to remove the finished product, and clean up the waste residue. In addition, different batches of incoming materials have different diameters of raw material cores. [0003] The existing core drilling work has the following two problems. Problem 1: The vertical clamping process of the raw material core will caus...

AI Technical Summary

Problems solved by technology

[0003] The existing core drilling work has the following two problems. Problem 1: The vertical clamping process of the raw material core will cause displacement, and the verticality is inaccurate; Problem 2: Every time a core is drilled, the radial drill adjustment must be repeated The concentric state between the drill bit and the raw material core is time-consuming and labor-intensive, and the work efficiency is low
