Description

Technical Field

[0001] The utility model relates to the technical field of drilling equipment, in particular to a three-stage telescopic tower structure for a drilling rig ranging from 6.6 meters to 15 meters. Background Art

[0002] Most of the existing special drilling engineering machinery such as water well drilling rigs, anchor drilling rigs, photovoltaic drilling rigs, etc. are equipped with single-arm or two-stage telescopic tower structures. The materials used to produce the towers are 3.5 meters, 6.6 meters or 9.6 meters in length. The longer the stroke of the equipment tower, the more serious the bending deformation of the welded and assembled steel. If high-standard materials are used, the production cost will be greatly increased. At present, the single tower structure in the industry can achieve a stroke length of about 13 meters, but because the equipment size is too long, it needs to be disassembled and transported in parts. Otherwise, the transportation of the whole machine will be seriously overloaded and overlong, which will bring great transportation safety hazards during the transfer construction. The deformation and bending limits of the profiles of the existing two-stage telescopic tower structure are basically 9 meters in stroke, which cannot cover all aspects relative to material utilization and construction conditions. The 12- and 15-meter towers need to be coordinated with deep foundation construction such as pile foundations, which cannot meet the rapidly developing construction design needs.

[0004] To achieve the above-mentioned purpose, the utility model provides a three-stage telescopic tower structure for a drilling rig with a range of 6.6 meters to 15 meters, including an outer tower, an intermediate tower, an inner tower, a slide, a power head, a lifting mechanism and a transmission mechanism. The outer tower, the intermediate tower and the inner tower are all provided with slide rails, the intermediate tower is slidably connected to the outer tower via the slide rails, the inner tower is slidably connected to the intermediate tower, the slide is slidably connected to the inner tower, the power head is fixedly connected to the slide, and the lifting mechanism and the transmission mechanism have multiple groups, which are respectively arranged between the outer tower, the intermediate tower, the inner tower and the slide.

[0005] The above technical solution is adopted, and the three-level telescopic tower structure and sliding cooperation cover the one-time push and lift of 6-meter, 9-meter, 12-meter and 15-meter drill rods, which fully compensates for the production and manufacturing problems such as profile length limitation and welding thermal deformation; at the same time, it solves the transportation length problem of the single-arm drilling rig tower, and does not require disassembly and assembly or over-limit transportation, saving customers' assembly and construction and other operating costs and reducing transportation risks.

Compared with a single hydraulic cylinder, a larger stroke and thrust are obtained, and work efficiency is improved. At the same time, the dispersion loss of hydraulic transmission oil is reduced, and the maintenance cost of the entire hydraulic system is relatively low.

[0010] By adopting the above technical solution and utilizing the three-stage lifting and propulsion design of the drilling tower composed of a plate chain and a pulley block, the bending deformation of the overall structure after the total length of the tower structure is increased can be resisted, the transmission force can be decomposed, and the stability of the tower structure during extension and retraction can be improved.

[0011] Furthermore, the outer tower is fixedly connected to an assembly base, and the drilling equipment can be detachably connected through the assembly base.

[0012] The above technical solution and prefabricated structure are suitable for a variety of mechanical equipment, such as loaders, excavators, rotary drilling rigs, pile drivers and other machinery, breaking the original complete machine production mode of drilling rig-type engineering machinery equipment, and changing the original professional drilling rig structure into an equipment structure system of accessories, solving the problem of large amounts of idle customer complete machine resources, making efficient use of them and saving capital investment.

[0013] Furthermore, the outer tower is also fixedly connected to a first-level transverse bracket, and the first-level transverse bracket is overlapped on the drilling rig equipment.
