Description

[0001] Emergency Descendable Actuator [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a self-weighting type actuator for opening and closing a sluice gate, and more particularly to a self-weighting type actuator having a front decelerating portion, (Self-weight drop) can be easily and surely implemented without the need for a self-weight reduction switching clutch, and the electric power and manual drive are automatically switched even without an electric manual switching clutch, and the driving of the self- Which can be independently performed regardless of the driving of the self-weighting type actuator.

In general, a spindle type opening / closing actuator or a spindle type actuator (hereinafter referred to as an opening / closing actuator or an actuator) for opening and closing a water gate is provided with a screw continuously arranged on a circumferential surface of a connecting rod spindle configured to open and close the water gate main body with a spindle type actuator A screw is provided on the final shaft of the switch so as to be screwed with the spindle so that the driving force generated by the transmission portion of the switch or the manual driving portion opens and closes the gate via the deceleration portion.

In addition, a conventional screw spindle type actuator has a spindle and a spindle gear. Therefore, when abnormal weather such as heavy rainfall or typhoon occurs unexpectedly and it is necessary to shut off the waterway by the waterway urgently, the spindle and the spindle gears are accumulated, and even if the self- It is necessary to shut off the water channel only by the manual driving which takes a long time to close the water gate. Therefore, there has been a structural problem of the switch connected to a large flood.

Conventional screw spindle type actuators are constructed of spindle and spindle gears, and have structural problems such as buckling of spindles, which can not be applied to the waterway with high efficiency of more than 15 tons or high efficiency of more than 30% .

In order to solve these problems, the present applicant has developed a self-weighting type actuator having a gear spindle (Patent Registration No. 10-0858281). However, such a self-weighting type actuator has various problems .

(1) In the conventional gear weight drop actuator, the main deceleration portion and the power connection portion, which are the deceleration portions, are arranged concentrically at the lower portion of the self weight portion. Therefore, when the opening / closing speed of the water gate is 0.4m / min, the reduction ratio becomes about 1/3,200. Such a conventional self-falling weight type actuator is excessively large in the ratio of the weight of the watercraft to the weight of the watercraft itself, so that the watercraft may be lifted or lowered very slowly when the watercourse is driven by its own weight in emergency or by manual driving. There was a safety problem that could not be solved. This problem occurs because the decelerating device is concentrated at the lower end of the self-weight drop portion.

(2) In the conventional self-weighting type actuator, the self-weighted lower portion and the manual-driven portion disposed at the front end of the driving portion implement the electric driving and the manual driving or the self-weight lowering driving through the hydraulic interrupter so that the driving force is interrupted . Therefore, a separate hydrostatic interrupter is further provided, so that the structure is complicated and the driving operation is complicated accordingly.

(3) In the conventional self-weighting type actuator, the self-weight reduction switching clutch for interrupting the driving of the manual driving portion and the self-weight reduction portion is disposed, so that the self-weight reduction switching clutch must be operated whenever the manual driving and the self- Therefore, there is a problem that the structure is complicated and the driving operation is complicated because the self weight strengthening switching clutch is further provided.

(4) In the conventional self-weighting type actuator, the protruding length is increased by arranging the manual driving part, the lower right weight part, the power interrupter, the driving part, the main reduction part and the power connection part in a straight line, , And the operation lever for driving the self-weight lowering drive is arranged at a position away from each other. Therefore, there has been a safety problem in that automatic and electric driving can not quickly operate the operation levers in the switching operation required for the self-falling driving operation and manual driving in an emergency situation.

(5) In the conventional self-weight drop type actuator, the manual drive section and the self-weight drop section are disposed at the front end of the drive section. Therefore, there has been a safety problem in that, in the event of an emergency, such as when a malfunction occurs in the driving section, or when a malfunction occurs in the power interrupter, it is impossible to operate the subordinate-speed descent driving or the manual driving.

(6) In the conventional self-weighting type actuator, an manual manual switching device for interrupting the driving of the manual driving portion and the self-weight lowering portion is disposed, and the manual manual switching device should be operated whenever the manual driving and the self- Therefore, there is a problem that the structure is complicated and the driving operation is complicated because the electric manual switching device is further provided.

In order to solve the above problems, the applicant of the present invention has developed a self-weighting type actuator having a gear spindle (Patent Registration No. 10-1046715). However, such a self-weighting type actuator has a problem in that, In addition to the problems (1) to (6), the following problems have additionally arisen.

(1) A manual clutch in the form of a jaw clutch that interrupts the driving force of the manual driving portion between the driving portion and the main reduction portion to realize the electric / manual automatic conversion, a first jaw clutch selectively engaged with the driving clutch, And a second jaw clutch of the conversion clutch and a jaw clutch of the manual clutch are engaged while an elastic force is generated in the conversion spring. When the drive clutch is rotated, The manual jaw clutch of the conversion clutch is engaged with the drive clutch. However, when the manual jog clutch is switched from the manual drive to the electric drive, the manual jaw clutch in the stopped state and the high- The coupling of the driven clutch with the tension of the conversion spring without a conversion clutch is like a manual conversion gear of a car In reality, there was almost impossible problem.

(2) When the conventional deceleration type actuator performs the first deceleration in the pre-deceleration section, the amount of deceleration to be handled by the main deceleration section is reduced accordingly. Therefore, the cycloid decelerating device configured to be suitable for a large reduction ratio has a problem in that the construction is complicated, the space is wider than necessary, and the cost is high.

An electromagnetic brake (not shown) installed in the drive unit 200 is automatically opened when the power is turned on. At this time, the drive shaft 303 is in a state capable of electric drive.

The clutch compression plate 435 is brought into close contact with the disk 431 and the friction plate 432 toward the clutch casing 420 by the elastic force of the coil spring 433 without any additional operation, The shaft 305 and the two orthogonal axes 415 are connected to each other.

[ In this way, the driving force decelerated from the first deceleration section 300 to the first deceleration section 1/40 to the 1/80 deceleration section subtracts the deceleration amount of the pre-deceleration section 300 from the main deceleration section 700, thereby performing the second deceleration.

Then, the automatic conversion unit 500 operates as follows when the vehicle is in the same vehicle. First, when the worm wheel 2 603 of the manual drive unit 600 brakes the rotation of the worm tooth 2 602, the driving unit 200, the pre-deceleration unit 300, the self-weighted lower unit 400, Axis 415 and the feed-in hub 510 sequentially. At this time, the bevel gear 1 (511) and the bevel gear 4 (541) and the bevel gear 5 (551) which are engaged with each other double in the take-in hub 510 are connected to the rotary hub 501 and the center hub 530, Axis 560, the rotation two-axis 570, and the rotation link connection port 504, respectively. The three orthogonal axes 502 coupled to the center hub 530 are disposed on the output hub 520 and ride on the tooth surfaces of the non-rotating bevel gear 2 521 and are centered about the center hub 530 in the circumferential direction The three orthogonal axes 502 coupled to the hub 530 are rotated and the driving force is transmitted to the power transmitting portion 610.

The driving force transmitted to the second shaft 710 is first reduced through the second pinion 711 and the second reduction gear 712 and then the driving force transmitted to the third shaft 720 is transmitted to the third pinion 712. [ Shaft 820 and the driving force transmitted to the tuned 2 axis 820 is transmitted to the spindle 830 through the double spindle portion 800. [ . That is, when the tuned two-shaft 820 rotates, the synchronized gear 2 802 and the spindle gear 2 804 fixed thereto are rotated, and the synchronized gear 2 802 and the synchronized gear 1 802 engaged with the synchronized gear 2 802 (801) is rotated. When the synchronizing gear 1 801 is rotated, the synchronizing shaft 810 is rotated and engaged with both spindle gears 803 and rotated.

The spindle 830 is moved up and down by the spindle gear 1 803 and the spindle gear 2 804 which are driven to be engaged with both sides of the spindle 830, ).

With this configuration, the main deceleration unit 700 having a simple configuration and occupying a narrow space can be constructed without employing the cycloid speed reducing apparatus.

The self-weight drop driving, which is a preferred embodiment of the present invention, will now be described with reference to FIGS. 1 to 3, 5 to 10, and 12.

If the water level suddenly rises suddenly during the opening and closing of the water gate 100 in the electric drive mode and the water gate 100 suddenly drops to reduce its own weight and it is necessary to cut off the water channel or if the electric drive is not possible due to a power failure, So that the self weight drop selector lever 441 of the self weight drop lower portion 400 is set to the operation position ON.

In this case, the self-weighted lower portion 400 is operated by operating the self-weight lowering switching lever 441, which is invisible to the two orthogonal axes 415, to the operating position ON, The multiple plate clutch 430 is disengaged and the orthogonal shaft 305 and the two orthogonal shafts 415 are separated from each other and the self weight of the hydrograph body 110 ). &Lt; / RTI > In this way, only when the operation of the self-weight reduction switching device 440 is desired, operation is performed at the operating position ON, and when the operation is stopped, the self-weight reduction switching device 440 is automatically returned to the release position (OFF) by the elastic force of the coil spring 433.

The normal weight one-shaft 305 and the two orthogonal axes 315 are connected to each other because the weight reduction device 440 is automatically in the released position (OFF) due to the elastic force of the coil spring 433. Normally, The orthogonal 1 axis 305 and the orthogonal 2 axis 315 are blocked from each other by setting the weight reduction switching device 440 to the operation position ON so that the self weight drop driving is performed by the weight acting on the water gate main body 110 .

Since the descending speed of the hydrographic weight of the self weight drop portion constructed as described above is proportional to the rotation angle pushing the self weight drop selector lever 441 toward the front side, the angle at which the hydrograph body 110 can be safely reduced to its own weight is adjusted in the field. If the lowering speed is fast, the mechanical braking push-down plate 508 disposed on the mechanical braking shaft 506 of the mechanical braking unit 509 presses the friction pad 505 to control the rotational speed of the rotary bushing 501 When the depression of the mechanical braking push-down plate 508 is released, the rotary drum 501 is separated from the friction pad 505 by the elastic force of the coil spring 2 507, which is externally provided on the mechanical braking shaft 506, Simultaneous gates can be lowered quickly and safely.

In addition, the hydrograph weight drop rate of the self-weight drop portion constructed as described above is proportional to the rotation angle at which the self weight drop selector lever 441 approaches the self-weight drop selector lever limit 443. Therefore, when the speed at which the hydrograph body 110 can be safely lowered to its own weight is reached, the self weight drop switching lever limit 443 can be disposed at a position where the self weight dropping switching lever 441 can no longer be pivoted forward, Accordingly, the descending speed of the hydrograph body 110 is safely and rapidly lowered, so that the water gate can be quickly and safely lowered while the self-weight dropping gate is omitted while omitting the construction of the impact preventing spring or the mechanical braking section at the lower end of the water gate.

Accordingly, when the spindle 830 is pulled downward due to the self weight of the water gate 100, the spindle gear 1 803 and the spindle gear 2 804 of the double spindle portion 800 are rotated, The third reduction gear 722, the third pinion 721 and the third shaft 720 of the main reduction unit 700 are rotated while the second reduction gear 711 and the second pinion 712 are rotated, , And rotates the second shaft 710. When the second shaft 710 is rotated, the three orthogonal axes 502 are rotated by the power transmitting portion 610, and the spline 460 and the self-weighted lower portion 400 are interlocked. 12, the spindle 830 is urgently lowered by the own weight of the water gate 100 to close the water gate main body 110.

On the other hand, when the self-weighting ramp is in the same state, the automatic converting unit 500 releases the orthogonal one-axis 305 and the orthogonal two-axis 415 due to the operation of the self- It works the same as driving.

When the self-weight lowering switch lever 441 is pushed forward to release the operating force held at the operating position ON after the self-weight lowering drive is completed, the multiple-plate clutch is moved by the elastic force of the coil spring 433, It is automatically restored to electric drive.

The manual drive, which is a preferred embodiment of the self-weight reduction type actuator of the present invention, will be described with reference to FIGS. 1 to 3, 8 to 10, and 13.

When the self-weight reduction type actuator of the present invention is electrically driven and a power failure or failure of the electric motor 201 occurs, the electromagnetic brake incorporated in the electric drive unit 200 automatically brakes the drive shaft 303 in such a state that the drive shaft 303 can not rotate . If the worm gear 2 602 and the worm wheel 2 603 held in the engaged state and the manual handle 606 are rotated, the worm wheel 2 The power transmission unit 610, the main deceleration unit 700 and the double spindle unit 800 coupled to the main body 603 and the manual connection port 605 via the output hub 520, the automatic conversion unit 500, the power transmission unit 610, 110 are lifted up and down.

On the other hand, in the case where the automatic conversion unit 500 is in the manual operation mode, when the electric power is cut off to the driving unit 200, the electromagnetic brake built in the driving unit 200 brakes the rotation of the two orthogonal axes 415, 200, the pre-deceleration unit 300, the self-weighted lower portion 400, the two orthogonal axes 415 and the input hub 510 so that they can not be sequentially rotated. The driving unit 200, the pre-deceleration unit 300, the 1-axis orthogonal 305 and the 2-axis orthogonal 415 are braked and the input hub 510 coupled to the 2-axis 415 is braked do. When the manual handle 606 rotates the manual driving shaft 601, the worm gear 2 602 and the worm wheel 2 603 meshing with the worm gear 602 are rotated, and the bevel gear 2 521 ) Sequentially rotate. A bevel gear 521 disposed on the output hub 520 and a tuning hub 1 540 and a bevel gear 4 541 and a bevel gear 5 551 disposed on the tuning hub 2 550, Are connected to the rotary shaft 501 and the central hub 530 by a rotary shaft 1 560, a rotary shaft 270 and a rotary shaft connector 504, respectively. The three orthogonal axes 502 coupled to the center hub 530 are disposed on the input hub 510 and rotate in the circumferential direction about the center hub 530 on the tooth surface of the bevel gear 1 511, The main decelerator 700, the double spindle portion 800, the spindle 830, and the hydrographic body 110 are operated manually.

If the driving mode of the number-of-problem sounder 170 is set to the electric driving mode after the manual driving is finished, the manual driving is terminated and the electric driving is automatically restored.
