Description

A kind of diving trepan
Technical field
The utility model relates to trepan, but especially relates to a kind of top drive type hydraulic diving trepan of deep stratum operation.
Background technology
Trepan plays an important role in nation-building and process of economic development as a kind of large-scale mechanical engineering equipment.China's population dramatic growth in recent years, water supply volume increases year by year, and natural environment progressively worsens; Groundwater table constantly descends; Cause the anhydrous phenomenon of some local phreatic wells, must ask for the water source to layer deeper in order to obtain the water source, these situation have increased the application of diving trepan greatly.
In order to adapt to various stratum, guaranteeing has higher drilling efficiency, in recent years; Development abroad multiple drilling process; And many countries are arranged,, all become the diving trepan water of having produced various types serially like states such as the U.S., Germany, Japan, Sweden, Romanias.
The development of the diving trepan of China is main transformation by impact drill to rotary drill, by in bulk be that main the dress to car is master's transformation.The well-drilling technology that is suitable for is a kinds of processes method such as mainly develop into that the mud direct circulation is crept into, pump is inhaled reverse circulation drilling, gaslift reverse circulation drilling, air drilling, down-the-hole hammer drill are advanced by fabian system, the mud direct circulation method of creeping into.
Impact drill leans on the up-and-down movement of drilling tool, makes the drill bit impact shaft bottom with broken rock.It is simple in structure, but does not have the circulation well cleanup system, and the removing of landwaste and rig can not carry out simultaneously, thereby work efficiency is lower.
The swinging favourable turn utilizes its pot taper drilling tool rotary cutting soil layer.Size according to drilling tool is called cauldron awl and pannikin awl respectively, can be by manpower or power drive.The soil bits that downcut are fallen in the pot, rise to ground and draw off, and it is simple in structure, and work efficiency is low, can only be used for that general soil layer or sandy gravel diameter are not more than 10cm, water content is no more than 50% stratum.
In addition, existing also have multifunctional drill, and promptly same bench drill machine can adopt multiple drilling method, and the adaptive capacity of multifunctional drill is strong, high at the drilling efficiency on various stratum.But owing to must be equipped with the required equipment of various drilling process, the complete machine complicacy is heavy, power is big, cost is high, troublesome poeration.
Summary of the invention
The purpose of the utility model provides a kind of simple in structure, good stability, easy to operate, in the process of operation, can realize that speed change and circulation creep into, and can adapt to the diving trepan of different operating environment better.
The utility model is provided with frame, 2 hydraulic motors, the synthetic case of power, gearbox, kelly, driven drilling rod, drill bit, clamper and hydraulic cylinders;
Frame is a mast type derrick, and 2 hydraulic motors are located on the frame, and 2 hydraulic motor output shaft are connected with the 2nd power input shaft with the 1st power input shaft of the synthetic case of power respectively; The synthetic output shaft of the power of the synthetic case of power is connected with the power input shaft of gearbox, and the power output shaft of gearbox is connected with kelly, and kelly and the sealing of driven drilling rod are spirally connected; Driven drilling rod is a hollow drill pipe; Drill bit is located at driven drilling rod lower end, and clamper is located on the frame, and clamper is clamped in driven drilling rod bottom; The piston rod outer end of hydraulic cylinder is fixed in frame top, and the cylinder body of hydraulic cylinder is connected with kelly.
Said mast type derrick is preferably the rectangle trussed construction.
Said hydraulic motor is preferably the variable displacement hydraulic motor.
The synthetic case of said power is preferably the synthetic case of the power that is made up of gear pair, and the synthetic case of power is provided with 2 power input shafts and 1 synthetic output shaft of power, 2 power input shafts respectively with 2 hydraulic motors in 1 hydraulic motor power output shaft be connected.
Said gearbox is preferably the gearbox that is made up of gear pair, and gearbox is provided with the duplicate gear and gearshift driving lever that is used for engage a gear.Gearbox is two grades of shift cage.
Compare with prior art, the beneficial effect of the utility model is following:
The utility model synthesizes the power of 2 hydraulic motors; And through the rotation of speed changer drive kelly; Make the rotation of driven drilling rod and drill bit, form the swinging working method, can drive kelly, driven drilling rod and drill bit through hydraulic cylinder again simultaneously and carry out the motion of straight line advance and retreat; Can realize like this circulating and creep into, accomplish entire work process.Driven drilling rod is a hollow, can inject mud in the hollow and be used for cools reamer head and get rid of detritus.Owing to adopt hydraulic control, the utility model operation is more convenient, in the process of operation, can realize speed change, can better adapt to different working environments.Because gearbox can be realized two grades of speed changes through stirring of duplicate gear, the fluid,matching pressure device then can be realized infinitely variable speeds simultaneously, can better meet the working condition requirement of different geological stratifications like this.Mast type derrick is suitable for vehicle-mounted.Hydraulic cylinder can adopt long stroke hydraulic cylinder, can carry out deepwater work (as reaching about 300M) like this.This shows, the utlity model has simple in structure, good stability, easy to operate, in the process of operation, can realize that speed change and circulation creep into, can adapt to the diving trepan of different operating environment better.
