Tower-caterpillar integrated core drill machine arranged at the front side of drill tower

Abstract

A tower-caterpillar integrated core drill machine arranged at the front side of a drill tower comprises a caterpillar (1), a base (2), a hydraulic support leg (3), a common vertical shaft type core drill machine (4), a lifting tower cylinder (5), a leaning tower cylinder (6), a tower base (7), the drill tower (8) and a siding tower cylinder (9), wherein a common vertical shaft type core drill machine bit (41) is positioned at one side in front of the common vertical shaft type core drill machine (4); the drill tower (8) is positioned at the other side in front of the common vertical shaft type core drill machine (4); a bottom tower (81) is movably arranged below the drill tower (8); and the drill tower (8) and the bottom tower (81) are arranged on the tower base (7) by a sliding tower device. The drill tower can slide upwards and downwards; when the drill tower leaves from ground, the transport of the drill machine and the walking of the drill tower are facilitated; when the drill tower contacts with ground, the stability of the whole machine during working is improved; and compared with the prior art, the tower-caterpillar integrated core drill machine has the characteristics of convenience for operation, good stability, a compact structure, transport convenience, low power consumption, low failure rate in construction, low manufacturing and maintenance costs, and the like.

Description

technical field [0001] The invention relates to a core drilling rig with integrated tower crane and shoe, in particular to a core drilling rig with a tower crane and shoe integrated at the front side of the drilling tower, in which the drilling tower is installed on the front side of a common vertical shaft core drilling rig. Background technique [0002] At present, core drilling rigs are widely used in geological and mineral resources exploration, hydrology, water wells, and large-caliber engineering construction. ) The core drilling rig is the most practical, and this type of drilling rig is as large as the following two models: a core drilling rig with a tower crane on the top of the drilling tower and a fully hydraulic core drilling rig. [0003] (1) Drilling tower top-mounted tower crane integrated core drilling rig [0004] The top-mounted tower crane crawler integrated core drilling rig is formed by installing the crawler on the lower part of the ordinary vertical s...

AI Technical Summary

Problems solved by technology

[0005] 1. Poor stability: Since the drilling tower is located above the ordinary vertical shaft core drilling rig, the stability of the whole machine is poor, especially when drilling inclined holes and pulling out;

[0006] 2. Poor operability: After the drilling tower is erected, it still needs to do a series of actions to start drilling, and it is frequently folded and assembled, and the same is true when the tower is retracted, so the operability of this type of machine is relatively poor;

[0007] 3. It is inconvenient to take out the drill pipe: when pulling out the drill, because the current position of the drilling tower has moved back a certain distance compared with the position when drilling, the lifting direction of the wire rope and the lifting direction of the drill pipe form an included angle. It brings some difficulty to take out the drill pipe

[0010] 1. High manufacturing and maintenance costs: Due to the current quality of domestic hydraulic components, this type of machine often fails due to problems with hydraulic components during work, which affects production. Many hydraulic components rely on imports, which greatly increases manufacturing costs. , if a failure occurs, it will be quite troublesome to repair, and the maintenance cost is very expensive;

[0011] 2. Large power loss: Because this kind of drilling rig converts mechanical kinetic energy into hydraulic power, and then converts hydraulic power into mechanical kinetic energy to carry out drilling work, the power loss is relatively large;

[0012] 3. The volume is large, and it is not very convenient to carry, so it cannot be widely used in the industry
