Description

A kind of rotary drilling rig

Technical field

The utility model relates to the construction machine field, especially foundation engineering machinery.

Background technology

Rotary drilling rig is an engineering piles hole construction machinery, and its structure is to give unit head by the diesel powered on the crawler body by hydraulic system transfers, and unit head drives drilling rod and drill bit (bucket) revolution, and play drilling rod and drill bit descends and lifting of hoist engine is finished bore operation.

The Spiral digging machine of domestic production at present substantially all is the product of companies such as imitated German precious pretty young woman company, Italian native power, because motor and reduction box in the unit head are contained in boring tower top, increased the height of unit head, the drilling rod leading truck is arranged on the drilling rod top, so just certainly will increase the height of boring tower, influence drilling depth, its profile bulkiness that also seems, and when drilling rod is installed, easily break motor and reduction box.Main winch is arranged on the boring tower rear portion or is arranged on the chassis postmedian, not within operator's sight line, is difficult for finding the disorder cable fault of the frequent landing appearance of hoist engine, is directed at wire rope and damages fault rate, wire rope spoilage height.Boring tower all adopts back type, can not lean forward, and promptly can not do the crane effect.These problems affect the optimization of rotary drilling rig structure, the performance of function and the safety of operation.

Summary of the invention

The purpose of this utility model is for providing the rotary drilling rig of a kind of structure optimization, handling safety and functional diversities.

The technical scheme that realizes the foregoing invention purpose is:

A kind of rotary drilling rig, has caterpillar chassis, boring tower, drilling rod, drilling bucket, the elevator unit, hydraulic system, unit head, boring tower is that folding FC boring tower is connected with the oil cylinder that leans forward, boring tower top is folding arm, the bottom is a fixed arm, folding arm has by a side with fixed arm and can turn to 180 ° folders to be connected, on the top of opposite side fixed arm collapsible leading block is housed, power head device is below the fixed arm and the oil cylinder connector that leans forward, unit head is made up of the power set of top and the leading truck of below, boring tower is connected with caterpillar chassis by folding shape linking arm, and folding shape linking arm is in the front lower place of pulpit.

In the power set framework, be provided with hydraulic motor and reduction box.

Major and minor hoist engine is arranged in the folding shape linking arm.

Technique scheme shows that boring tower of the present utility model is a folded form, can operate the oil cylinder that leans forward when transportation, earlier boring tower is fallen down forward, will fold 180 ° of arm side direction commentaries on classics and fixed arm then and overlap; To fold 180 ° of arm backwards rotation earlier when dropping into construction, be connected, and operate the oil cylinder that leans forward again boring tower is erected with fixed arm.After folding arm is folding, the collapsible leading block of opposite side is outwards overturn, make the oblique support of boring tower by secondary hoist engine wire rope, can make the utility model form crane, use as crane.

Drilling rod can be guaranteed the verticality of holing by center two point locations of unit head output shaft hole and leading truck positioning shaft hole.Hydraulic motor and reduction box device form built-in unit head in the unit head framework, major and minor hoist engine is located in the folding shape linking arm, forms built-in hoist engine, improved device ', and profile is succinct, and is small and exquisite.

The utlity model has following beneficial effect:

1, boring tower has adopted accordion structure, and unit head has adopted power set and the two-in-one structure of guide peg, and device optimized structure, reduced volume below the oil cylinder connector that leans forward of fixed arm, uses more convenient, transport faster.

2, power set are arranged in the unit head framework, have increased the safety of equipment, and major and minor windlass device places in operating personnel's the sight line in folding shape linking arm, can in time find fault, guarantee to construct and carry out smoothly.

3, owing to adopted folding FC boring tower, and collapsible leading block is housed, makes the utility model can hoisting heavy, increased the function of crane, a tractor serves several purposes in the end of fixed arm.

Description of drawings:

Fig. 1 is the structural representation of a kind of rotary drilling rig of the utility model:

Fig. 2 is a unit head side-looking structure chart;

Fig. 3 is unit head plan structure figure;

Fig. 4 is that the A of Fig. 1 is to view.

The title of each sequence number is as follows among the figure:
