Abstract
The invention discloses a winch drum assembly with an electromagnetic eddy current brake device. The winch drum assembly comprises a winch drum which is installed on a winch frame wallboard through a drum shaft, a bearing seat and a bearing, one end of the drum shaft is provided with a chain wheel, the other end of the drum shaft is provided with a rotor through a key, and a stator is arranged in the rotor and fixed on the winch frame wallboard and the bearing seat; a coil is arranged in the stator and sealed and fixed through a coil shield. According to the winch drum assembly, the electromagnetic eddy current brake device and the winch drum are designed into an integrated structure, the requirement of drilling equipment such as a drilling-in unit, a truck-mounted drilling rig and a workover rig which have the width limit for cooperative using is met, the structure is simple and compact, the axial size is small, the weight is small, and the manufacturing cost of the complete machine is greatly reduced. The winch drum assembly can be widely applied to a winch with the width, weight and structure limit.
Description
Technical field
The present invention relates to the drilling equipment field in energy extraction industry, particularly relate to a kind of winch drum assembly with electromagnetic eddy current brake device.
Background technology
At present in the boring winch of well, coal bed gas and petroleum natural gas exploration application, increasing use electromagnetic eddy current brake, mainly because electromagnetic eddy current brake uses electromagnetic induction principle, carry out noncontact without wearing and tearing braking, mechanical wear is not had in brake process, regulate exciting current just adjustable lock torque, moment large, long service life, simple operation and other advantages when there is low speed; And because electromagnetic eddy current brake major part is air-cooled, there is no huge water-cooling apparatus, there will not be equipment scaling, freezing, the phenomenon that blocks and get rusty yet.But electromagnetic eddy current brake is general to be all linked by tooth clutch or denture clutch and winch drum shaft, whole winch oad is increased; Particularly for the matching used winch drum of drill outfit that some drilling-in units, truck-mounted drilling rig and service machine etc. have width to limit, by drive chain case connection, electromagnetic eddy current brake device can only be installed, although do not increase the width of winch, but because the restriction of locus also has very large difficulty when specific design is arranged, and complex structure, weight also increases a lot; Assist brake and winch stressed severe by what become, from before moment of torsion become moment of torsion and add moment of flexure, have impact on the service life of equipment.
Summary of the invention
The technical matters that the present invention solves: design a kind of winch drum assembly with electromagnetic eddy current brake device, electromagnetic eddy current brake device and drum winder are designed to integral structure, the drill outfit that meeting truck-mounted drilling rig and service machine etc. has width to limit supports the use, simple and compact for structure, axial dimension is little, lightweight, save the manufacturing cost of complete machine greatly.
Technical solution of the present invention: a kind of winch drum assembly with electromagnetic eddy current brake device, comprise winch drum, described winch drum is arranged on winch frame wallboard by drum shaft and bearing seat, bearing, sprocket wheel is equipped with in one end of described drum shaft, the other end of described drum shaft is provided with rotor by key, be provided with stator in described rotor, described stator is fixed on winch frame wallboard and bearing seat; Be provided with coil in described stator, and coil is fixing by the sealing of coil guard shield.
Further, outside described rotor, guard shield is housed, and guard shield is directly installed on winch frame wallboard.
Further, the annular space formed between described coil guard shield and stator is connected with drip pipe.
The present invention compared with prior art changes the connection mode of original winch drum and electromagnetic eddy current brake device, electromagnetic eddy current brake device and drum winder are designed to integral structure, the drill outfit that meeting drilling-in unit, truck-mounted drilling rig and service machine etc. has width to limit supports the use, simple and compact for structure, axial dimension is little, lightweight, save the manufacturing cost of complete machine greatly.Can be widely used on the winch having width, weight and structural limitations.
Accompanying drawing explanation
Fig. 1 is integral structure schematic diagram of the present invention.
Detailed description of the invention
1 a kind of embodiment of the present invention is described by reference to the accompanying drawings.
A kind of winch drum assembly with electromagnetic eddy current brake device, comprise winch drum 1, described winch drum 1 is arranged on winch frame wallboard 10 by drum shaft 2 and bearing seat 11, bearing 12, sprocket wheel 3 is equipped with in one end of described drum shaft 2, the other end of described drum shaft 2 is provided with rotor 5 by key 4, be provided with stator 6 in described rotor 5, described stator 6 is fixed on winch frame wallboard 10 and bearing seat 11; Be provided with coil 7 in described stator 6, and coil 7 seals by coil guard shield 9 fixing.The guard shield 8 of electromagnetic eddy current brake is directly installed on winch frame wallboard 10.
The annular space 13 formed between described coil guard shield 9 and stator 6 is connected with drip pipe 14, and the condensed water that stator 6, coil 7 cool rear generation flows out by drip pipe 14, ensures that annular space 13 is inner dry, the service life of extension coil.
Drum shaft rotor driven synchronous axial system when the present invention works, produces braking force when coil 7 is energized, plays the effect of assist brake.The present invention changes the structure composition of original electromagnetic eddy current brake completely, and electromagnetic eddy current brake itself does not have axle, bearing, bearing seat, end plate and supporting outer guard shield, utilizes the part of winch that electromagnetic eddy current brake and winch are combined together.
Above-described embodiment, just preferred embodiment of the present invention, is not used for limiting the scope of the present invention, therefore all equivalent variations done with content described in the claims in the present invention, all should be included within the claims in the present invention scope.
