The used electric drive system of used electric drilling machine winch mostly is two kinds, a kind of is the AC-SCR-DC transmission, another kind is the AC-DC-AC transmission, two kinds of type of drive are compared, the latter is steady with its startup, strong, the permanent power adjustment of overload performance is big, the power-factor of load is high, can become the developing direction of electric drive rig with advantages such as the permanent moment of torsion output of extremely low speed, electrical motor brushless sparks.
Summary of the invention
The utility model purpose is a kind of gear transmission clutch shift churn winch of design.It makes full use of the advantage and the clutch shift characteristic of AC-DC-AC transmission, need not adopt special wideband high-speed electric expreess locomotive, high precision drop-gear box, imported bearing etc., can effectively reduce winch manufacture difficulty and cost, guarantee that simultaneously winch has desirable speed and promotes characteristic, to improve the drilling well work efficiency, improve winch processing and manufacturing difficulty, reduce production costs etc.
Specifically, a kind of gear transmission clutch shift churn winch, its alternating-current variable frequency motor as power (1) connects with gear reduction box (3) through coupler (2), and power-transfer clutch (5,6) is installed on the output shaft of gear reduction box (3) and this output shaft and connecting with drum shaft (4) behind coupler (7); Described power-transfer clutch is divided into speed end power-transfer clutch (5) and low speed end power-transfer clutch (6), and these two power-transfer clutchs are installed on the output shaft of gear reduction box (3).
The other end of drum shaft (4) brakes with small machine drill feeding facility (9) or Eton or electromagnetic eddy current brake connects.
On the input shaft of gear reduction box (3), (having only a master with main motor (1)
During motor) the coaxial small machine drill feeding facility (9) that is equipped with.
Described small machine drill feeding facility comprises small machine (12), retarder (11), power-transfer clutch (10); Small machine (12) output shaft connects with power-transfer clutch (10) by retarder (11), this power-transfer clutch (10) connect with drum shaft (4) or with drop-gear box input shaft one client link.
The small machine drill feeding facility also can be connected with one-level gear case or drive chain case after by power-transfer clutch (10), and this one-level gear case or drive chain case connect with drum shaft (4) or be installed in drop-gear box input shaft one end.
The utility model main brake adopts hydraulic disc brake (8).
The main motor (1) of the utility model winch is one or two, and these two main motors all connected with gear reduction box (3) by shaft coupling (2) when main motor was two.
The utility model structurally not only drop-gear box be gear reduction box, winch has two gears, unsnaps or hangs and close (annotate: during normal operation, one of power-transfer clutch is in the state that closes of hanging, one and is in the state of unsnaping) and implement gear shift by two power-transfer clutchs; And the automatic bit feed of winch send brill with main motor under normal conditions, stops to send with the electric-controlled hydraulic dish under ulf and bores or adopt the small machine drill feeding facility to send brill.Therefore, the utility model compared with prior art, winch motor can adopt coventional type alternating-current variable frequency motor (being that range of motor speeds is at 0-1100r/min or high slightly) to get final product, need not adopt special wideband high-speed electric expreess locomotive (maximum speed of revolution surpasses 2200r/min), the drop-gear box precision can suitably reduce, and bearing adopts that common homemade bearing can meet the demands etc., has solved the height of winch accuracy requirement in the past, problems such as manufacturing cost height, winch hoisting speed are slow, inefficiency.The utility model winch has low cost of manufacture, and the winch range of speed is big behind the height quick change shelves, and high efficiency is easy to realize characteristics such as manual intelligent, automation control.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
Accompanying drawing has provided a kind of embodiment of the present utility model.The design plan of electricity driven wheel drive clutch gear shifting type winch is: electric driven wheel drive clutch gear shifting type winch is by main motor (one or two alternating-current variable frequency motors, three kinds of functions are arranged: promptly power, energy consumption assist brake and send brill), coupler (totally two kinds, two or three, can be air tube clutch or push-plate power-transfer clutch) assembly of elements such as gear reduction box, power-transfer clutch (two), drum shaft, hydraulic disc brake, small machine drill feeding facility form.
, connect as active force by two (or one) alternating-current variable frequency motors (1), and connect rear driving drum axle (4) work through coupler (7) through two (or one) coupler (2) and gear reduction box (3).Gear reduction box output shaft two ends are equipped with two power-transfer clutchs (5) (6) and are used for winch height quick change shelves, and main brake is stopped (8) for the hydraulic pressure dish, and assist brake is energy consumption of electrical machinery braking (1).Send the brill mode to adopt small machine automatic driller (9) or the hydraulic pressure dish automatic bit feed (8) of stopping.If require in the ordinary course of things to send the drilling speed degree bigger, also can adopt main motor (1) automatic bit feed.
Adopt alternating-current variable frequency motor by the gear reduction box transmission, the reduction gearbox output shaft two ends are equipped with two power-transfer clutchs, and winch is unsnaped or hung to close and realize winch height quick change shelves by two power-transfer clutchs.
Automatic bit feed is in the rear end of main electric machine rotational axis one coder to be installed, and by the signal of encoder feedback, electric-control system is in time adjusted and sent the brill motor operating parameter, thereby reaches the purpose of index drum rotating speed or moment of torsion, and realization constant speed or constant voltage are sent brill.Consider the harmonic interference of alternating-current variable frequency motor under extremely low frequency, therefore when rig requires to send the drilling speed degree big, can utilize main motor to implement to send brill.Sending under the very low situation of drilling speed degree requirement, automatically switching under the state of surging by the electromagnetic valve that surges and utilize control oil pressure enforcement dish to stop to send brill; Perhaps adopt small machine to realize sending brill through retarder deceleration rear driving drum axle.
Assist brake also can be by installing Eton brake or electromagnetic eddy current brake etc. except that adopting main motor (1) resistance braking on drum shaft.
The utility model electricity driven wheel drive clutch gear shifting type winch can be applicable on the AC frequency conversion rig of present all models.
