Abstract
The utility model relates to a skid-mounted digital control electrical winch which consists of a digital variable frequency motor, a speed reducer, a roller, a key sleeve, a pinion, a big gear wheel, a chain, a spindle, a brake strap, a right lateral plate, a left lateral plate, a cover plate, a rectangular base, a front plate, an encoder interface and a power supply interface. The digital variable frequency motor is horizontally connected with the speed reducer by the key sleeve and is arranged at one end of the rectangular base; the roller is arranged at the other end of the base in a mode that the roller is parallel to the digital variable frequency motor; the roller and the spindle are fixedly arranged on the left lateral plate and the right lateral plate of the base by bearings; the speed reducer and the pinion are connected with the big gear wheel of the roller by the chain; the roller and the brake strap are fixedly arranged on the right lateral plate; and the skid-mounted digital control electrical winch is provided with the following digital control circuit that the digital variable frequency motor is connected with an AC (Alternate Current) servo driver by a power line and a signal and a speed regulator arranged on the digital control circuit is circumferentially and sequentially connected with a speed ring or a current ring, a power amplifier, the digital variable frequency motor, an encoder, a velometer and a forward and reverse switch by the forward and reverse switch.
Description
One, technical field
The utility model relates to a kind of oil water well test instrument, the digital control electric winch of specifically a kind of skid-mounted type.
Two, background technology
In the present domestic measurement well process; Be used to remove the equipment great majority employing hydraulic driving mode of steel wire or cable; Be exactly to drive Hydraulic Pump by automotive engine or alternating-current motor/AC motor to produce highly pressurised liquid; Output to HM Hydraulic Motor by highly pressurised liquid through high pressure fuel pipe, drive HM Hydraulic Motor again and rotate, and drive steel wire or cable reel operation.Because automotive engine or alternating-current motor/AC motor drive Hydraulic Pump, drive HM Hydraulic Motor again to driving cylinder, its power just reduces, decrease in efficiency, rotary speed unstabilization, influence test effect and quality.
Three, summary of the invention
The purpose of the utility model provides the digital control electric winch of a kind of skid-mounted type, solves the problem that above-mentioned prior art HM Hydraulic Motor drives the reduction of cylinder power, decrease in efficiency, rotary speed unstabilization, influence test effect.
The technical scheme of the utility model realizes in the following manner:
The utility model is made up of digital frequency conversion motor, retarder, cylinder, key cover, miniature gears, big gear wheel, chain, main shaft, brake band, right side board, left side board, cover plate, base, header board, encoder interfaces and power interface; It is characterized in that the digital frequency conversion motor links to each other with key cover level with retarder; And be arranged on an end of rectangular base; The cylinder other end that is installed in base in parallel; On the left side board and right side board of base, retarder chain rack pinion links to each other with the big gear wheel of cylinder through chain drum spindle through bearing fixing, and back band is fixed on the right side board; The digital control circuit of the digital control electric winch of skid-mounted type is that the digital frequency conversion motor is connected with signal with power lead with AC servo driver, and speed regulator set on the digital control circuit links to each other with speed ring or electric current loop, power amplifier, digital frequency conversion motor, coder, velometer and positive and reverse steering switch by preface through the direct-reverse switch hoop.
Compared with present technology the utility model has that power output is constant, efficient is high, stabilization of speed, and speed is that stepless change, test mass are good, testing efficiency is high.

Five, the specific embodiment
For further disclosing the technical scheme of the utility model, elaborate through embodiment below in conjunction with Figure of description:
As shown in Figure 1, the utility model is made up of digital frequency conversion motor 1, retarder 2, cylinder 3, key cover 4, miniature gears 5, big gear wheel 6, chain 7, main shaft 8, back band 9, left side board 10, right side board 11, cover plate 12, base 13, header board 14, encoder interfaces 15, power interface 16 and digital-control circuit.The digital frequency conversion motor links to each other with key cover level with retarder, and is arranged on an end of rectangular base; The cylinder other end that is installed in base in parallel.Drum spindle is horizontally fixed on through bearing on the left side board and right side board of base, and the retarder miniature gears links to each other with the big gear wheel of cylinder through chain, and drum brake is fixed on the right side board.The digital control circuit of the utility model is: digital frequency conversion motor and AC servo driver link through power interface and encoder interfaces; As shown in Figure 2, set speed regulator 1 on it ' through direct-reverse switch 2 ' hoop and speed ring or electric current loop 3 ', power amplifier 4 ', digital frequency conversion motor 1, coder 5 ', velometer 6 ' with direct-reverse switch 2 ' be connected.During use direct-reverse switch is transferred to turning to of needing, governing speed, makes the speed rotation of winch by adjustment, drive steel wire or cable and remove tester, reach at the uniform velocity and remove, steady testing is raised the efficiency the purpose with test mass.
