A top drive core drilling rig

Abstract

A top-drive type core drill comprises a drill tower 1, a tower top pulley block 2, a tower base 3, an integrated power head 4, a drill stem 5, a main winch 6, a main lifting rope 7, guide pulleys 8 and guide ropes 9. The tower top pulley block 2 is located at the top of the drill tower 1. The main lifting rope 7 stretches out of the main winch 6, and penetrates through the tower top pulley block 2 to be connected with the integrated power head4. The guide ropes 9 are located at the two sides of the integrated power head 4, and the upper ends and the lower ends of the guide ropes 9 are all fixedly connected so as to be tensioned. The guide pulleys 8 are installed on the two sides of the integrated power head 4. The upper end and the lower end of each side of the integrated power head 4 are each provided with two pulleys which are arranged in parallel, wherein the guide ropes 9 are arranged between the two pulleys. By adoption of the technical scheme, a plurality of drill stems can be installed in the drill compared with the prior art, operation is simple, power waste is reduced, the working efficiency is greatly improved, and integrated control can be achieved easily.

Description

technical field [0001] The invention belongs to the field of geological exploration equipment, and in particular relates to a top drive type core drilling machine. Background technique [0002] figure 1 Shown is the most commonly used core drilling rig in the geological exploration industry today, which is mainly composed of the following parts: input power 101, gearbox 102, frame 103, winch 104, power distribution box 105, drill pipe 106, power Head 107, feed cylinder 108, guide rod 109 and bevel gearbox 111. [0003] The effect of each part of existing core drilling rig is as follows (input power 101, gearbox 102, frame 103 are not described): [0004] 1. The winch 104 is generally used in conjunction with the drill tower built on the construction site, and is mainly used for hoisting the drill pipe 106, so that the drill pipe 106 can be loaded into the power head 107 or removed from the power head 107. [0005] 2. The power distribution box 105 is used to distribute th...

AI Technical Summary

Problems solved by technology

[0014] 1. The operation is cumbersome and the work efficiency is low

The upward movement distance of the power head is limited by the stroke of the feed cylinder, and the up and down movement distance is limited. If the upward movement distance is too large, the stability of the power head will become poor, so a drill pipe is all drilled into the ground, and the power head needs It can be completed by reciprocating up and down several times; and when loading drill pipes, only one piece can be installed at a time.

[0015] 2. Large waste of power

The input power has been transmitted for many times, and it has changed from horizontal rotation to vertical rotation, resulting in a lot of waste of power

[0016] 3. Limited drilling force

[0017] 4. It is difficult to realize integrated control
