Abstract

The utility model discloses an electric release fishing device and belongs to a special fishing device for oil fields and oil wells. The electric release fishing device is composed of an output connector, a motor protective cylinder, a motor, a motor base, a motor fixing bolt, a key, a protective cylinder sealing ring, a connecting base, a bearing block sealing ring, a bearing block, a bearing block jackscrew, a screw rod, a sleeve, a coupler, a motor base jackscrew, a thrust bearing, a bearing spacer, a deep groove ball bearing, an upper spring and a lower spring, a guide post and a clutch part, wherein the output connector is hermetically connected with the motor protective cylinder; the motor is arranged on the motor base and fixed by the motor fixing bolt; the coupler is connected with the key; the motor protective cylinder is hermetically connected with the connecting base through the protective cylinder sealing ring; the motor base is in threaded connection with the connecting base through the motor base jackscrew; the thrust bearing and the deep groove ball bearing are sealed by the connecting base, the bearing block and the screw rod by adopting the bearing block sealing ring; the motor drives the screw rod to rotate in a forward and reverse manner. The electric release fishing device provide by the utility model has the advantages that the usability is improved effectively, unnecessary failures and maintenance are eliminated, the operation is convenient, adjustment is not needed after installation, the maintenance is convenient, the performance is reliable, and the electric release fishing device is not affected at normal low temperature condition.

Description

The power-driven release fishing device

Technical field

The utility model relates to a kind of dragging for of using for oilfield and puts special purpose device, specifically a kind of power-driven release fishing device.

Background technology

At present, the art is known to a kind of electric fishing and puts its structure of device and be comprised of out splice going splice, motor casing, motor, motor cabinet, shaft coupling, key, bearing, travel switch, stroke switch mounting base, bearing separation pad, Connection Block, bearing gear, leading screw, sleeve, lead, oil sealing, clutch part, spring etc.Its operating principle is: the rotating by motor drives the leading screw rotation, and clutch part is moved up and down, realize slinging weight and input weight; And the motor outage is controlled automatically by travel switch.Its shortcoming is: 1. facts have proved that the travel switch job stability is too poor, fault is many, and difficulty is adjusted in maintenance, need detachable maintaining, change part, and repeatedly dismantle, repeatedly adjust and test just and can reach and should produce effect, but also be difficult to guarantee useful life, malfunctioning once just use in well, loss is too many, delays again construction speed, suppresses in addition the possibility of bad motor.2. bearing seal is unreliable: only by an oil sealing, prevent that bearing from contacting with water, fact proved and do not reach effect, during winter job, bearing is freezed to death malfunctioning.

Summary of the invention

In order to overcome after existing electric fishing is put the device outage, by travel switch, automatically control, the winter job bearing is malfunctioning, poor work stability, fault is many, the shortcoming of maintenance difficult, the utility model provides a kind of power-driven release fishing device, and this device has overcome the not good and insecure problem of bearing seal of travel switch result of use, effectively raise functional performance, stopped unnecessary fault and maintenance.

The technical scheme in the invention for solving the technical problem is: a kind of power-driven release fishing device, and by out splice going splice, motor casing, motor, motor cabinet, motor set bolt, key, casing sealing ring, Connection Block, bearing gear sealing ring, bearing gear, bearing gear jackscrew, leading screw, sleeve, shaft coupling, motor cabinet jackscrew, thrust bearing, bearing separation pad, deep groove ball bearing, upper and lower spring, lead, clutch part forms; Out splice going splice and motor casing are tightly connected, and motor is sitting in motor cabinet, and the motor set bolt is firm; Described shaft coupling connects with key, motor casing and Connection Block have adopted the casing sealing ring to be tightly connected, motor cabinet and Connection Block adopt the motor cabinet jackscrew to be threaded, and Connection Block, bearing gear and leading screw utilize bearing gear sealing ring that thrust bearing and deep groove ball bearing are closed; Described motor positive and inverse drives leading screw and rotates, and clutch part is moved up and down, realize slinging weight and input weight.

The beneficial effects of the utility model are: this device has overcome the not good and insecure problem of bearing seal of travel switch result of use, effectively raises functional performance, has stopped unnecessary fault and maintenance.This utility model is simple in structure, easy to operate, install after without adjusting, be convenient to maintenance, dependable performance, durable in use, under normal natural low temperature, be not affected.

The accompanying drawing explanation

Accompanying drawing 1 is structural representation of the present utility model.

1 out splice going splice in figure, 2 motor casings, 3 motors, 4 motor cabinets, 5 motor set bolts, 6 keys, 7 casing sealing rings, 8 Connection Blocks, 9 bearing gear sealing rings, 10 bearing gears, 11 bearing gear jackscrews, 12 leading screws, 13 sleeves, 14 shaft couplings, 15 motor cabinet jackscrews, 16 thrust bearings, 17 bearing separation pads, 18 deep groove ball bearings, 19 upper and lower springs, 20 leads, 21 clutch parts.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described: as shown in Figure 1, a kind of power-driven release fishing device comprises that out splice going splice 1 and motor casing 2 are tightly connected, described motor 3 is sitting in motor cabinet 4, motor set bolt 5 is firm, described shaft coupling 14 use keys 6 connect, motor casing 2 and Connection Block 8 have adopted casing sealing ring 7 to be tightly connected, motor cabinet 4 and Connection Block 8 adopt motor cabinet jackscrew 15 to be threaded, Connection Block 8, bearing gear 10 and leading screw 12 utilize bearing gear sealing ring 9 that thrust bearing 16 and deep groove ball bearing 18 are closed, realized with liquid isolated, neither affect relevant motor function, the phenomenon of also having avoided being subject to cold service and having affected normal use occurs, described lead 20 and sleeve 13 have played the effect that prevents clutch part 21 radial rotatings, described motor 3 rotatings drive leading screw 12 and rotate, clutch part 21 is moved up and down, sling weight and throw in weight of realization, the now motion of clutch part 21 with stop threading off and realize in upper and lower limit by the threads of lead screw pair, rather than realize by stopping operating of motor 3, so also avoided the phenomenon of suppressing bad motor 3 to occur, threads of lead screw pair upper, lower limit stroke is 40 millimeters, and screw thread pair again in conjunction with the pretightning force of top, lower spring 19 and realize.
