Problems solved by technology

The height of the existing geological drilling rigs is generally only 12.5 meters at most, which cannot meet the market demand in the reality that geological exploration continues to explore deeper
Moreover, in terms of transportation, the existing geological drilling rigs in the market rely on dismantling and transportation, and then carry out secondary assembly and placement on the construction site, and a crane is needed to achieve smooth installation, and the auxiliary work and auxiliary time are relatively increased.
At the same time, the locking device of the existing geological drilling rig is connected by bolts. When locking, it needs to be manually operated at a height of more than 10 meters, and the risk factor is very high.

Embodiment Construction

[0011] As shown in Figure 1 and Figure 2, the 18-meter hydraulic lifting and retractable drilling tower consists of a crown block 1, an upper tower body 2, a second-floor platform 3 (stand support), a limit locking device 4, a lifting mechanism 5, a lower The tower body 6, the vertical tower oil cylinder 7, the vertical tower support 8, the drop tower support 9 and the drilling tower chassis 10 constitute.

[0012] Drilling tower chassis 10 is an integral welded structure of section steel. Vertical tower support 8 is welded into an A-frame by rectangular square tubes, which are directly welded on drilling tower chassis 10. The lower tower body 6 and upper tower body 2 are welded with seamless steel pipes to form a truss structure. , the lower tower body 6 is connected with the vertical tower support 8 through the hinge support 20, the upper tower body 2 is set in the lower tower body 6, and the lifting mechanism 5 composed of a hydraulic winch can realize flexible extension and...

Abstract

A 18m hydraulic lifting flexible drilling tower is formed by a crown block, an upper tower, a two-layer table, a limit locking device, a lifter, a lower tower, an upright tower cylinder, an upright tower support, a fall tower support and a drilling tower chassis. The crown block is formed by three front and two back block groups, to be connected on the top of the upper tower via bolts, the drilling tower chassis is integral steel, the upright tower support is welded into A-shaped support via welding rectangle square tube to be welded on the drilling tower chassis, the lower and upper towers are welded via seamless steel tube into truss structure, the lower tower and the upright tower support are connected via a hinge base, the upper tower is sheathed in the lower tower, the upright tower cylinder is formed by two-stage flexible cylinder, the two-layer table is welded from steel tubes to be connected at 12.5-8.2m of the drilling tower via flanges, and the fall tower support is welded from section steel. The invention can drill 18m deep, with improved bearing ability, high efficiency and reduced cost.

Description

technical field [0001] The invention relates to equipment in geological drilling construction in the geological exploration industry, in particular to a drilling tower. Background technique [0002] At present, in the geological exploration industry, geological drilling towers, which are one of the necessary equipment for drilling construction, have similar types, but the breakthrough in tower height and automatic expansion and contraction are not very prominent. The height of the existing geological drilling rigs is generally only 12.5 meters at most, which cannot meet the needs of the market in the reality that geological exploration continues to explore deeper. The market requires the emergence of geological drilling rigs with greater heights. Moreover, in terms of transportation, the existing geological drilling rigs in the market rely on dismantling and transportation, and then carry out secondary assembly and placement on the construction site, and a crane is needed to...
