Embodiment
Main thought of the present invention changes traditional manual control mode, controls running and the stopping of speed reducer by installing electromagnetic brake on the input shaft of pumping unit speed reducer.Below embodiment is described in detail, but not as a limitation of the invention.
As Figure 1-5, the invention provides a kind of pumping unit braking device, be applied to oil-field oil pumper.Braking device comprises speed reducer 1 on pumping unit and electromagnetic brake 2.The function of electromagnetic brake 2 described in this is speed reducer 1 is shut down within very short time and lock is firmly motionless.In the present embodiment, electromagnetic brake 2 comprises main brake disk 21, braking plate 22, is braked dish 23 and magnetic hoop combination 24, this magnetic hoop combination 24 can adopt any electromagnetic brake of the prior art, the spring 241 used in such as the present embodiment and the composite structure of yoke 243, its effect is exactly: during energising, utilize electromagnetic force to produce suction, main brake disk 21 Compress Spring 241, makes to produce distance between main brake disk 21 and braking plate 22; During power-off, the restoring force of spring 241 promotes main brake disk 21, until main brake disk 21 is squeezed in braking plate 22.Braking plate 22 is placed on the input shaft 11 of speed reducer, and is fixed on the input shaft 11 of speed reducer by external tooth cover 25 in spline mode; Main brake disk 21 and magnetic hoop combination 24 are locked integral by braking release bolt 5, and are placed in a shell 26.Main brake disk 21 and be braked between dish 23 and carry out recessed bond ing by hexagon socket head cap screw 6 and hollow adjusting bolt 7, as long as gap can ensure the braking distance of main brake disk 21, such as, gap is 1-2mm.Be braked dish 23 to be connected with box body of speed reducer 12 by changeover panel 3, this changeover panel 3 is provided with 6 fixed holes, and changeover panel 3 is fixed on described box body of speed reducer 12 by 6 corresponding bolts 4.Preferably, be braked dish 23 and be connected as a single entity by supporting element 31 with described changeover panel 3, can ensure that being braked dish 23 coaxially installs with speed reducer input shaft 11 so better.Install and mix up brake disc 21 and braking plate 22 gap, take-off the brake release bolt 5, now in braking state, after control cabinet is powered to electromagnetic brake 2, brake release, pumping unit enters accurate running state.
Speed reducer input shaft 11 is connected with braking plate 22, whole electromagnetic brake 2 is fixed on box body of speed reducer 12, when electromagnetic brake 2 is cold time, main brake disk 21, be braked between dish 23 and braking plate 22, closed under the pressure of spring 241, produce powerful frictional force, stop the running of speed reducer.After electromagnetic brake 2 is energized, main brake disk 21 suction is opened 1 ~ 2mm by the magnetic force that electric current produces through coil, after braking plate 22 has lacked the resistance of main brake, just can freely operate.
In order to ensure the safety guarantee of pumping unit, being provided with 2 in the housing 26 of described electromagnetic brake and adding and turn round bolt 8, described in add the front end turning round bolt 8 and act on described main brake disk 21, and the movable of certain distance can be formed.Add and turn round bolt 8 and adopt and manually operate, when forward precession, add and turn round bolt 8 and squeeze and push away main brake disk 21 until by braking plate 22 locking, lock the braking state of described electromagnetic brake; Otherwise, then brake off state.
In order to realize the safe handling of above-mentioned further guarantee braking device, the present invention is directed to braking device and have employed intelligent control, basic technical scheme is: when 1. control cabinet is powered, electromagnetic brake and brake off, and pumping unit enters running state, and power-off is braked at once; 2. due to the Real-Time Monitoring of control system, run and unmanned at pumping unit, when there is sucker rod and surprisingly breaking de-, electromagnetism self acting brake can be braked at once, pumping unit is slowed down to equinoctial point stopping under the resistance of braking brake, thus avoids the generation of the accidents such as the damage of pumping unit mechanical part or overturning.
As shown in Figure 6, the 380V power supply of three-phase four-wire system, from L1, L2, L3, N input, opens QS1 access point table through total lock sky.SB1 above panel is system stop button, and SB2 is system start button, and SB3 is pattern switch knob, for the switching of energy saver mode with power frequency pattern.
By SB1 pushbutton enable system, the auxiliary normally opened contact of KM1 closes self-locking simultaneously, and system obtains electric work.KM2 and KM3 carries out logical interlock on circuit, for the switching of control mode, prevents from causing power supply short circuit when switch mode.When SB3 is switched to energy saver mode, KM3 closes self-locking, and the normally-closed contact of KM3 disconnects simultaneously, and make KM2 disconnect control loop, motor accesses servo driver by KM3, and servo driver and energy consumption feedback unit are devoted oneself to work.
According to operating mode, the Current Voltage of the real-time regulation output of servo driver, the moment keeps the active power of motor to be the optimum state.When counterweight of oil pumping unit do not mate, downhole environment change time, oil pump running speed certainly will be caused to be greater than speed set by control, while now servo driver control motor keeps original speed, the energy it fed back feeds back to electrical network through feedback unit, allow system save the energy expenditure of half operation cycle, thus reach further power saving effect.
If when having cause specific can not adopt energy saver mode, SB3 can be switched to power frequency pattern, by SB1 halt system, after system stops, again press SB2 start up system, KM2 closes, and KM3 disconnects, and motor directly accesses electrical network by KM2 and operates.
Described servo driver is provided with BK1, BK2 two tenminal blocks, connects outside described electromagnetic brake; The action of described electromagnetic brake is controlled by auxiliary reclay KL; When KL connects, electromagnetic brake take-off the brake sheet; When KL disconnects, electromagnetic brake closes braking plate; Wherein, KL is controlled by contact KM2 and k1, k2 two contact, and k1, k2 connect the inner normally opened relay of servo driver; When adopting power frequency pattern, KM2 closes, and powers to while motor, and connect KL and close, BK1, BK2 output voltage gives outside electromagnetic brake, makes its take-off the brake sheet; When adopting energy saver mode, servo driver is guaranteeing output voltage control motor, and in trouble-free situation, closed internal relay, connects k1, k2 2 point, closed KL, to power take-off the brake sheet to outside electromagnetic brake by BK1, BK2; In the power save mode; the servo driver moment controls operating voltage and the electric current of motor, when the disconnected bar of appearance, or when other mechanical failures occur; due to the sudden change of motor load; cause the change of electric current, when exceeding set scope, servo jumps error protection; internal relay discharges; k1, k2's is separated, and KL is power-off immediately, electromagnetic brake also power-off locking.Slowly equinoctial point is slipped down under the resistance that pumping unit brakes at electromagnetic brake.Thus play a protective role.
Touch screen directly adopts the 24V Power supply of servo driver inside, and adopts 485 buses between servo driver, MODEBUS communication protocol communication.Simplify Systematical control, by the real-time current of motor, voltage, rotating speed etc., from driver, that reads simultaneously, then shows in the mode of chart, facilitates the analysis of data.
Certainly; the present invention also can have other various embodiments; when not deviating from the present invention's spirit and essence thereof; those of ordinary skill in the art can make various corresponding change and distortion according to the present invention, but these change accordingly and are out of shape the protection domain that all should belong to the claim appended by the present invention.
