Abstract
The utility model discloses a parallel structure for a diesel engine and a motor of a mechanical combined drilling rig. The parallel structure comprises a diesel engine, a sensor, at least two hydraulic couplers, at least one motor and a parallel carriage, wherein one end of one hydraulic coupler is connected at the output end of the diesel engine, and the other end of the hydraulic coupler is connected with the parallel carriage; one end of the other hydraulic coupler is connected with the output end of the motor, and the other end of the other hydraulic coupler is connected with the parallel carriage; and the sensor is arranged at the output end of the diesel engine. The parallel structure has the advantages that the operation of speed control is simple and convenient, the load is balanced, and the like.
Description
Technical field
The utility model relates to the oil-gas drilling technical field, exactly relate to diesel engine and motor on a kind of rig and bassinet structure.
Background technology
Through retrieval; In the rig industry, technology now relatively more commonly used all is to adopt diesel engine or the diesel engine unit drive unit as rig, is CN2908754 like publication number; The Chinese patent document that open day is on June 6th, 2007 discloses the device of a kind of diesel engine and speed-adjusting type hydraulic deceleration positive wagon and car driven oil drilling rig; Comprise diesel engine, speed-adjusting type hydraulic deceleration positive wagon, base, be equipped with diesel engine, speed-adjusting type hydraulic deceleration positive wagon on the base, diesel engine, shaft coupling, speed-adjusting type hydraulic deceleration positive wagon, shaft coupling connect successively; Adopt many diesel engines to add speed-adjusting type hydraulic deceleration positive wagon; Through belt or chain and car drive rig, adopt speed-adjusting type hydraulic deceleration positive wagon, rig is carried out stepless speed regulation; Also make every diesel engine torque equilibrium; Play buffering, absorbing, flexible effect of transmitting simultaneously; Also can prime mover and working machine have connected or separately, play the effect of clutch.
But at present, the compound rig of mechanical gradually adopts industrial electrical network to drive two motors as the well site electrical source of power, and two diesel engines that replace former rig have become development trend as drilling well power, and keep a diesel engine as emergency power.When handling the down-hole special operation condition, need to use the mode of two motors and diesel engine and car more reliable power to be provided as rig, there are following problem in motor and diesel engine and car:
(1) the velocity setting controller is different, is difficult to realize that speed synchronization is given.Motor changes resistance value through speed-regulating hand wheel and then regulates the given magnitude of voltage of governor, regulates motor speed in this way; Diesel engine changes diesel engine speed through the size of control throttle.
(2) the electrical machinery characteristic of frequency conversion drive is harder, and is difficult to realize load balancing behind diesel engine and the car.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of machinery and combination drill diesel engine and motor and bassinet structure, it is simple and convenient to the utlity model has speed control operation, advantages such as load balancing.
The utility model is realized through adopting following technical proposals:
A kind of machinery and combination drill diesel engine and motor and bassinet structure; It is characterized in that: comprise diesel engine, sensor, at least two fluid couplings, at least one motor and and the compartment; Wherein: fluid coupling one end is connected in the output of diesel engine, and the other end connects said and compartment; Another fluid coupling one end connects with the output of a motor, and the other end connects said and compartment; Sensor is installed on the output of diesel engine.
Said fluid coupling is two, and motor also is two.
Compared with prior art, the beneficial effect of the utility model shows:
Output at diesel engine is equipped with sensor; Be used to detect rotating speed and obtain current signal; Deliver to the set-point of governor as motor, such frame mode, the speed of motor and diesel engine is only by the diesel engine oil gate control; Simple to operation, the load of motor and diesel engine is unbalanced≤and 5%.
Description of drawings
To combine the Figure of description and the specific embodiment that the utility model is done further to specify below, wherein:
Fig. 1 is the structural representation of the utility model
Mark among the figure: 1, diesel engine, 2, sensor, 3, fluid coupling, 4, motor, 5 and the compartment.
The specific embodiment
Referring to Fig. 1; The utility model comprises sensor 2, fluid coupling 3; Sensor 2 is installed in 1 output of diesel engine and detects the rotating speed size, converts tach signal to the 4-20mA current signal, delivers to the velocity setting value of governor as motor 4 after handling through PLC.When diesel engine and motor and car, only need to regulate diesel engine throttle, the electromotor velocity handle remains on the zero-bit state, and the velocity setting value of motor and diesel engine is consistent, and makes motor identical with the rotating speed of diesel engine.
With a fluid coupling 3 one client link diesel engines 1 output, the other end connects compound box 5; All the other two fluid coupling 3 one ends connect two motors 4 outputs respectively, and the other end connects compound box 5; Because there is slippage at work in fluid coupling, the even power division between them when many engine rotating speeds are slightly different, thus reach the purpose of many engine chains and car load automatic equalization.
Claims (2)
1. a machinery and combination drill diesel engine and motor and bassinet structure; It is characterized in that: comprise diesel engine, sensor, at least two fluid couplings, at least one motor and and the compartment; Wherein: fluid coupling one end is connected in the output of diesel engine, and the other end connects said and compartment; Another fluid coupling one end connects with the output of a motor, and the other end connects said and compartment; Sensor is installed on the output of diesel engine.
2. machinery according to claim 1 and combination drill diesel engine and motor and bassinet structure is characterized in that: said fluid coupling is two, and motor also is two.
