Description

Water door hoisting device

The present invention relates to a hydrologic hoisting device, and more particularly, to a hydrologic hoisting device which allows the lifting and lowering operation of a hydrological opening and closing of a hydrologic door to be made conveniently and quickly.

In general, the waterway hoist device 300 for lever-type waterway in which manual operation is performed is shown in Figures 9 and 10. The configuration is largely rotated in one direction by interlocking with the one-way rotation lever 301 and the lever 300. The first gear 305 so that the gear is engaged with the first pinion gear 303 of the first shaft 304 in which the band brake 302 and the first pinion gear 303 are installed. And a second pinion gear 306 to which the gear is coupled to the second shaft 308 having the open gauge 307 mounted on one side thereof, and the second pinion gear 306 of the second shaft 308. The second gear 309 and the rack gear 310 are arranged in a third shaft 311 is provided.

The lever 301 is provided with a one-way clutch 317, and is used while changing the rotational operation direction on the first shaft 304 in accordance with the rising and lowering of the water gate during use.

The fourth shaft 313 is provided with a centrifugal brake 312 which controls the sudden drop of the water gate while engaging the gear with the brake drum 302 via the one-way clutch A on the first shaft 304.

In addition, the rack gear 310 of the third shaft 311 is combined with the rack gear bar 314 to lift it, the sluice gate 315 is connected to the rack gear 314 is installed.

When the water gate is an interlocking type, the auxiliary shaft device 316 is connected to the third shaft 311 to raise and lower the water gate 315.

When the lever-type hoisting device 300 reciprocates the lever 301, which is installed through the one-way clutch 317 on the first shaft 504 via the first shaft 504 when the water gate is raised, the first shaft 304 is While rotating in one direction, the band brake drum 302 is fixed to the first pinion gear 303 and the key handle 318 (in this case, the key handle is released in the case of the lowering of the hydrologic gate). Only rotate the one-way clutch (A) fixed to).

Accordingly, the first gear 305 of the second shaft 308 connected by coupling the gears to the first pinion gear 303 is subjected to the first deceleration rotation, and the rotation of the second pinion gear 306 installed on one side is performed. As the second gear 309 of the three axes 311 is rotated by the second deceleration, the rack gear 310 is rotated.

The rack gate 314 is raised by the rotation of the rack gear 310 at all times to open the water gate 315.

When the lock is lowered, the band brake drum 302 is rotated by changing the lever 301 in the rotational operation direction, assembling the first shaft 304, and then rotating the key handle 318.

Accordingly, the centrifugal brake 312 of the fourth shaft 313 connected to the band brake drum 302 generates a frictional force and lowers it while preventing a sudden drop of the water gate.

The present invention is made of a three-stage reduction of gear, so the operator must continue to operate the lever in front and rear reciprocating motions during hydrologic lifting, thereby increasing fatigue and reducing the front and rear operating range of the lever. It requires a lot of hoisting time, which lowers the efficiency of hoisting and cannot set and set the fine hoisting position. The hoisting device also has a large load, so it must be manufactured to be durable. There is a problem that the smooth hoisting operation is not made.

In addition, since the one-way clutch is used for the lever when the water gate is lifted, there is a problem in that it is cumbersome and uncomfortable during the hoisting operation such that the lever should be assembled to the shaft so that the rotational operation direction of the lever is changed according to the direction of the water lift operation.

Therefore, the present invention is designed to solve the problems of the prior art, the object of the present invention is to install the rack gear on the reducer output shaft of the hydrologic lifting device for opening and closing the waterway, adopting the six-speed gear reduction, convenient lifting operation as a handle It relates to a hydrostatic hoist device that is made quickly and quickly.

There is a hydrostatic lifting device comprising a lifting means for lifting and lowering the water gate with the rotational force decelerated by the deceleration means to rotate the rack gear installed on the six axles.

In the manual actuating type of the hoisting device of the present invention, by pushing the clutch of the power control device with the power connection handle 28 of the power connection device, the power transmission and the interruption are made.

Then, the operation handle 06 of the operation device is rotated so that the secondary shaft gear 04 engaged with the primary gear 02 is first decelerated to rotate the secondary shaft.

The rotational force transmitted through the second axle is sequentially decelerated up to sixth in the deceleration means, and the rotational force is transmitted to the first elevating means, thereby raising or lowering the rack bar 25 connected to the water gate to open and close the water gate.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The hydrostatic lifting device is composed of a steering wheel operating device (10A), a power control device (50A), a power connection device (100A), a reduction gear (150A).

Power coupling device (100A) has a structure in which the clutch 09 is assembled to the secondary shaft 03 at right angles to the secondary shaft 03, the interior of the clutch 09 can slide with the secondary shaft 03. In order to transmit the rotational force, the spline is dug into the inside of the second axle (03) and the clutch (09) to transmit the rotational movement, and a plurality of clutch disc plates (09-) are provided on the outer circumferential surface of the clutch (09). 4) and the friction disk plate (09-3) are inserted in a direction perpendicular to the secondary shaft, the clutch housing (09-1) is wrapped around the outer peripheral surface, and a plurality of housing disk plate (09-2) inside the secondary shaft and It is inserted between the friction disk plates 09-3 in the perpendicular direction.

Rotating the power connection handle 28 rotates the warm gear 10 to rotate the warm wheel 07. At this time, the female screw in the center of the dangerous wheel 07 is assembled with the male screw on the outer peripheral surface of the feed screw shaft 08. When the feed screw shaft 08 is moved forward while sliding with the outer circumferential surface of the secondary shaft 03, the thrust bearing 08-1 inserted into the feed screw shaft 08 is pressed. When the compression spring 08-3 is compressed by pushing -2), a friction force is generated in the housing disc plate 09-2 and the clutch disc plate 09-4 to transmit power to the 2-1 axle.

When the power connection handle 28 is rotated in the opposite direction, the pressing plate 08-2 is retracted by the compression spring 08-3, and the feed screw shaft 08 is also reversed to interrupt the power.

In the power interruption device 50A, the shaft opposite to the clutch assay is provided with a one-way clutch assay capable of only one direction rotation of the secondary shaft.

The one-way clutch assay has a cam clutch (05) which is fixedly installed in the housing (05-1) to enable one-way rotation and a bushing (05-2) is inserted in the cam clutch (05) so that the secondary shaft (03) and the stopper (05-3) is fastened to the bushing (05-2) with a plate bolt (05-6) to prevent the separation of the cam clutch (05) and the housing is a body and a plurality of fixing bolts (05) -5) and maintain the gap with the pressing plate (05-4).

When assembled as above, when the power is connected by the power connection handle 28, the friction plate slips in the clutch assay by preventing the reversal in the cam clutch (05) during sudden descent due to the malfunction of the water gate, thereby protecting the safety of the operator. When operating the operation handle (06) is operated by being transmitted to the secondary shaft as it is power.

The deceleration device 150A is a device for decelerating the power connected to the second axle when the power is connected by the power connecting device 100A of the second axle. Receiving and transmitting to the 3 axle gear (14) through the 2-1 th gear (13) to deliver to the 4 axle gear (16) through the 3rd gear (15) 4 axle gear (16) through the 4th gear (17) When delivered to the 5 axle gear 18 through the 5th gear (19) to transfer to the 6 axle (20) through the 6 axle gear (21) sprocket 22 installed on the right side of the 6 axle is rotated at this time The rack bar 25 engaged in the perpendicular direction of the sprocket 22 is raised or lowered vertically, and at this time, the pin 26 penetrates from the outside of the main body to prevent the rack bar 25 from being separated. The guide roll 27 is inserted into the outer circumferential surface of the 26 to prevent separation.

At this time, the gear ratio is gradually increased from the first axle to the sixth axle, and the rack bar 25 can be lifted with less power or less power. When engaged with the pedometer watch wheel 24, the opening meter 11 for determining the lifting height is connected to the upper end of the pedometer watch wheel 24 and is installed (see Fig. 2).

The interlock device 200A connects the power of the reduction device 150A by connecting the coupling shaft 30 with the coupling 29 in the axial direction from the fourth axle gear 16 of the four axles of the reduction device 150A. When the power is sent to the device 200A and the power is connected by the power connection device 100A, it is received from the 4 axle 4 axle gear 16 of the 4 axle and transmitted to the interlock device 200A. It is transmitted to the sprocket inside the connection gear box 31 of 200A) and the transmitted power raises and lowers the rack bar 25 installed at right angles to the six axles.

The above-mentioned interlock device 200A is used when the interlocking type is used, and when the single-acting type is used, the coupling of the 4 axles can be disassembled (see Fig. 5).

As described above, when the hoisting device of the present invention is a manual single acting type (see Fig. 2).

When operating the power connection handle 28 of the power connection device 100A to connect power to the clutch assay, and operating the operation handle 06, the torque is de-energized because the clutch force is engaged over the second axle. It is possible to win water gate by transferring to 2-1, 3, 4, 5, 6 axle, and the ratio of gear is getting bigger from 1 axle to 6 axle and the rack bar 25 can be hoisted with less power or less power. On the one end of the 6 axle shaft, the dog gauge warhammer (23) is engaged with the dog gauge wheel (24) and the dog gauge (11), which can know the lifting height, is connected to the dog gauge wheel (24) and installed at the top. It is.

This design uses 6-speed reduction gears to lift without manual force in consideration of the conventional problems, and fine adjustment of the lifting height is also superior to that of the conventional hoisting machine, and directly connects the power connection device 100A. Adopted to ensure the connection and disconnection of power.

In the case of electric hoisting, the six-speed reduction gear is used to make the hoisting with less power than before. The gear ratio increases the rigidity of the hoisting device. In a convenient way to eliminate the fatigue of the operator.
