Description

Handle style hand-operated movable beam hydrowinder {Handle style winch for floodgat}

The present invention relates to a hand-operated manual double hydraulic door winch, which is greatly reduced in overall size, prevents damage to the drum drive shaft, and prevents shaking of the drum drive shaft. .

In general, a sluice is formed by blocking a water source such as a river or a river, installs a beam, raises the level of water for the purpose of dividing the water, and draws a structure that draws water through the water channel. Aqueducts are called fountains, and they control the flow of water on the channel.

On the other hand, in the streams near the city where there is a large river connected to the sea, if the level of the river which suddenly blows up due to flood or heavy rain at high tide cannot be controlled upstream, drainage is given priority to reduce flooding damage. The drainage door and drainage pumping station are composed together to open and close the drainage door and operate the drainage pump to drain.

In addition, in cities, water gates are installed in the cooling water system of tap water and water purification facilities, sewage facilities, and industrial plant facilities to control water flows in addition to rivers and rivers, to control the flow of water, and to control the water level of freshwater lakes formed in the basin of reclamation A drainage lock, which is a drainage facility for water storage, is installed to store water and to store and supply the irrigation water needed for reclaimed land. The remaining water is drained to the sea through the drainage lock.

Sluices for the various uses described above generally include a hydrologic body for opening and closing a waterway, a door frame driven by cylindrical rollers formed at both sides of the hydrological body to reduce frictional resistance generated during opening and closing of the hydrological body, In order to ensure the exponent between the door frame, the rubber is attached to the outer circumferential side of the hydrophobic body, and the hydrostatic hoist for generating the driving force required to open and close the hydrologic vehicle.

Hydrologic winch is a power generating unit for generating a driving force, a power switching unit for selecting electric or manual by intermittently driving the driving force generated in the power generating unit, and a hydrological vehicle with a driving force generated in the power generating unit. Speed reducer to the speed of opening and closing safely (0.3m / min to 1.0m / min) so that the rotating speed of the rotating shaft is reduced in proportion to the reduction ratio and the driving force is increased in inverse proportion to the reduction ratio, and the driving force increased in the reduction gear In order to open and close the hydrologic body vertically, the rack bar vertically connected to the top of the hydrologic body and the final pinion gear on the drive shaft of the rack bar and the reduction gear are formed as tooth gears to convert the rotational movement of the drive shaft into the vertical motion of the hydrologic body. Braking system equipped with a hydrological lifting device unit for opening and closing the hydrologic vehicle and multiple braking devices for safely controlling the hydrologic vehicle Opening and closing of the hydrometer and the hydrometer are formed by opening and closing limit switch which shows the opening degree between the wealth and the hydrologic body and the door frame. It includes a field operation unit to operate.

By the way, there are some problems with this conventional hydrowinder.

First, a rack bar of long length is installed vertically on both sides of the upper part of the gate to lift the gate, and auxiliary gear boxes are installed on both sides of the frame to lift the rack. Therefore, every time the gate is lifted, the rack bar of long length is elevated in the state protruding to the top of the gate, so a very large vertical installation space is required. In addition, the rack bars protruding largely toward the upper side of the floodgate do not harmonize with the surrounding landscape, thereby causing a problem that the surrounding landscape is damaged by the protruding rack bars.

Second, the coupling shaft is installed in the auxiliary gear box to raise and lower the rack bars. However, these coupling shafts are exposed to the outside and wear or damage occurs, and the damage of these coupling shafts also affects the power transmission relationship leading to the auxiliary gear box and the rack bar.

The coating layer 101 is coated around the drum drive shaft 100. The coating layer 101, after performing the sand blasting (Sand Blasting), cleaning (cleaning) operation of the drum drive shaft 100 to form a coating layer 101 around the.

Such coating layer 101 is a ceramic powder, chromium oxide (Cr ₂ O ₃ ) powder, aluminum oxide 96-98% chromium oxide (Cr ₂ O ₃ ) and 2-4% titanium dioxide (TiO ₂ ) is mixed (Al ₂ O ₃ ) powder, titanium dioxide (TiO ₂ ) powder, yttrium oxide (Y ₂ O ₃ ) powder, zirconia (ZrO ₂ ) powder, chromium nickel (Cr ₃ C ₂ 25 NiCr) powder (chromium carbide 75%, Nickel 20%, chromium 5%), any one type of powder is provided to have a powder particle size of 10 ~ 44㎛, the powder having the above particle size is made by spraying around the drum drive shaft (100).

Chromium oxide (Cr ₂ O ₃ ) serves to prevent rust by acting as a passivity layer that blocks oxygen invading into the metal.

Titanium dioxide (TiO ₂ ) is very stable physicochemically and has a high hiding power, thus becoming a white pigment. In addition, the refractive index is high, it is widely used in high refractive index ceramics. It has photocatalytic and superhydrophilic properties. Titanium dioxide (TiO ₂ ), air purification, antibacterial, harmful substance decomposition, pollution prevention function, discoloration prevention function. The titanium dioxide (TiO ₂ ), so that the coating layer 101 is reliably coated around the drum drive shaft 100, decomposes and removes foreign matter attached to the drum drive shaft 100 to damage the drum drive shaft (100). Prevent it.

Here, when chromium oxide (Cr ₂ O ₃ ) and titanium dioxide (TiO ₂ ) are mixed and used, the mixing ratio thereof is from 96 to 98% of chromium oxide (Cr ₂ O ₃ ) and from titanium dioxide (TiO ₂ ) 2 to It is preferred that 4% is mixed.

When the mixing ratio of chromium oxide (Cr ₂ O ₃ ) is less than 96-98%, the coating of chromium oxide (Cr ₂ O ₃ ) is often broken in an environment such as high temperature, and thus the drum drive shaft 100 ), The rust protection effect of the abruptly decreased.

When the mixing ratio of titanium dioxide (TiO ₂ ) is less than 2 to 4%, the effect of titanium dioxide (TiO ₂ ) was insignificant enough to fade the purpose of mixing it with chromium oxide (Cr ₂ O ₃ ). That is, titanium dioxide (TiO ₂ ) to decompose and remove the foreign matter attached to the circumference of the drum drive shaft 100 to prevent the drum drive shaft 100 from corrosion or damage, when the mixing ratio is less than 2 to 4% However, there is a problem that takes a long time to decompose the foreign matter attached.

When the aluminum oxide (Al ₂ O ₃ ) is formed as a coating layer 101 around the drum drive shaft 100, the coating is even and there is no gap, thereby reliably protecting the circumference of the drum drive shaft 100. The melting point of the aluminum oxide (Al ₂ O ₃ ) is very high to 2050 ℃ to protect the drum drive shaft 100 at a high temperature, there is a great effect on the oxidation prevention. Therefore, aluminum oxide (Al ₂ O ₃ ) coated on the drum drive shaft 100 prevents the drum drive shaft 100 from being oxidized by blocking seawater or air from contacting the circumference of the drum drive shaft 100.

Yttrium oxide (Y ₂ O ₃ ) is excellent in heat resistance, high temperature oxidation resistance and corrosion resistance, and is suitable for thermal spray coating in that it exhibits plasma corrosion resistance even in a plasma etching atmosphere.

Zirconia (ZrO ₂ ) is a heat-resistant material with a high melting temperature (about 2,700 ° C). It has low thermal conductivity, broad chemical stability from acidic to alkaline range, low thermal expansion, high strength and high hardness (more than 7.0 MOS hardness). ) Has excellent material properties such as friction resistance.

The chromium nickel (Cr ₃ C ₂ 25 NiCr) powder is made by mixing 75% chromium carbide, 20% nickel, and 5% chromium.

The coating layer 101 made of one selected from these materials has a thickness of 50 to 600 μm around the drum drive shaft 100, and maintains a hardness of 900 to 1000 HV and a surface roughness of 0.1 to 0.3 μm. Plasma coated.

The coating layer 101 is jetted around the drum drive shaft 100 at a speed of about Mach 2 by spraying a powder of one kind selected from the above-mentioned powder powder and the gas at 14000 ° C. (Diamond Wheel) and a film (Film) using a 50 to 600㎛ lapping.

If the thickness of the coating layer 101 is less than 50㎛, the effect by the above-described ceramic coating layer 101 is not guaranteed, if the thickness of the coating layer 101 exceeds 600㎛, while the increase of the above-described effect is insignificant There is a problem in that work time and material costs are wasted by excessive ceramic coating.

While the coating layer 101 is coated on the drum drive shaft 100, the temperature of the drum drive shaft 100 is increased. The drum drive shaft 100 is moved to a cooling device (not shown) to prevent deformation of the heated drum drive shaft 100. It cools and maintains the temperature of 150-200 degreeC.

The thermal spraying method for forming the coating layer 101 around the drum drive shaft 100 is a high-speed molten or semi-fused state by injecting metals, ceramics, and mixtures thereof into a hot gas-flame or plasma. It is a surface treatment technique which forms a film on the surface of a base material by spraying in the air.

When electrical energy is applied between the tungsten cathode and the Cu anode nozzle of the thermal spray, an arc is generated, and when a gas or a gas mixture flows, plasma is generated. In this case, plasma is dissociated into atoms when the molecular gas is heated to a high temperature, and when energy is added thereto, electrons are released. This state is useful as a heat source having a very high energy. The characteristics of the plasma jet as a thermal spraying source are as follows.

Since it is a heat source with high energy density, it is easy to spray a high melting point metal or ceramics. If the material is accompanied by a safe melting phenomenon such as metals, ceramics, plastics, and the like, spraying is possible, so the selection area of the coating material is high. Since the velocity of the plasma jet is high, the thermal spraying material is adsorbed on the workpiece at high speed, thereby obtaining a high adhesion strength and high density coating. It is easy to output large, so the amount of spraying per unit time is big, so workability is good and economy is high. It is oxygen-free, carbon-free and clean, thermochemically active heat source, so there is little contamination and change of thermal spray material.

Depending on the type and condition of the heat source, the temperature of the thermal spray particles, the dwell time, the contact time with the atmospheric gas component, in particular, the collision energy to the surface of the base metal, and the rapid freezing and condensing velocity vary. In other words, the physical and chemical properties of the thermal spray coating vary greatly.

The thermal spraying material injected into the plasma flame is heated and melted by a heat source and is flying at a high speed by the plasma jet. Since the molten particles in the air contact the air and rush to the base material with an oxide film formed around them, the thermal spray coating formed on the drum drive shaft 100 has a cross-sectional structure in which numerous particles of an oxide film are deposited on the surface. Will have

The powder particle size suitable for thermal spraying is preferably in the range of 10 to 44 µm. If the fineness of the thermal spray is less than 10 μm, it is easy to vaporize in the thermal spraying, and if the fineness of the thermal spraying is more than 44 μm, the powder particle size of the thermal spraying is preferably 10 to 44 μm. In addition, a great influence on the quality of the thermal spray coating is a particle size distribution, and when the particle size difference is large, the energy and flight trajectory obtained by each powder particle from the heat source are different from each other, thereby decreasing the uniformity of the composition and physical properties of the coating layer 101. Therefore, strict spray powder particle size distribution control is required.

It is preferable to be spherical within the above-described powder particle size in order to make the supply rate of the thermal spraying uniform and stable and to uniformly heat the supplied powder, that is, to improve the flowability of the molten particles.

A sealing material (not shown) made of chromic anhydride (CrO ₃ ) made of a metallic glass quartz system may be coated around the coating layer 101. Chromic anhydride may be applied around the coating layer 101 made of chromium nickel powder as an inorganic sealing material.

Chromic anhydride (CrO ₃ ) is used in places requiring high wear resistance, lubricity, heat resistance, corrosion resistance, and releasability, and does not discolor in the air, has great durability, and has good wear resistance and corrosion resistance. In the case where the silicide is coated around the coating layer 101, the coating thickness is preferably about 0.3 to 0.5 μm. When the coating thickness of the sealing material is less than 0.3㎛, the sealing material is easily peeled off and peeled even in a slight scratch groove, so that the above-described effects cannot be obtained. If the coating thickness of the sealing material is thick enough to exceed 0.5㎛, there are many pin holes, cracks, etc. in the plating surface. Therefore, the coating thickness of the sealing material is preferably about 0.3 to 0.5㎛.

An overhang prevention part 130 is installed at an upper portion of the frame 10 and one end of the drum drive shaft 100 at one side of the band brake 120 to prevent the drum drive shaft 100 from shaking.

The overhang prevention unit 130 is composed of a shaft support arm 131, the first coupling shaft 135 and the second coupling shaft 136, the bearing 137.

The shaft support arm 131 has a first shaft coupling hole 132 and a second shaft coupling hole 133 respectively formed at both sides of the lower end so as to be coupled to the lever installation frame 122, and the drum driving shaft 100 is coupled thereto. Bearing coupling hole 134 is formed in the upper center, and supports the rotation of the drum drive shaft (100).

The first coupling shaft 135 and the second coupling shaft 136 are coupled to the first shaft coupling hole 132, the second shaft coupling hole 133, and the lever mounting frame 122 of the shaft support arm 131. Both lower sides of the shaft support arm 131 are supported by the lever mounting frame 122.

The bearing 137 is coupled to the bearing coupling hole 134 of the shaft support arm 131 and the drum driving shaft 100 so that the rotating drum driving shaft 100 is supported by the shaft supporting arm 131.

The handle-type manual electric combined swing hydrowinder of the present invention having such a configuration is operated as follows.

When the geared motor 20 is rotated, the drive shaft 32, the drive gear 34 are rotated, and when the drive gear 34 is rotated, the first electric gear 36, the second electric gear 37 is rotated, the second When the electric gear 37 is rotated, the third electric gear 39, the fourth electric gear 40 is rotated.

When the fourth electric gear 40 is rotated, the fifth electric gear 42 and the drive sprocket 43 are rotated, and when the drive sprocket 43 is rotated, the electric chain 60 is driven to transmit the main gear box 50. When the sprocket 53 and the sixth electric gear 54 are rotated, and the sixth electric gear 54 is rotated, the seventh electric gear 56 and the eighth electric gear 57 are rotated. When the eighth electric gear 57 is rotated, the ninth electric gear 59 and the sixth electric shaft 58 are rotated.

When the sixth electric shaft 58 is rotated, the drum driving shaft 100 connected thereto is rotated, and the winding drum 110 is rotated accordingly. When the winding drum 110 is rotated, as the wire rope 111 is wound or unwound on the winding drum 110, the water gate 1 is raised or lowered.

Usually when the water gate (1) is lowered to operate the band brake 120 to control the drum drive shaft (100) rotated with the water gate (1) is lowered.

When the compression coil spring 127 is operated to brake the drum drive shaft 100 that is rotated, the upper ends of the first operating lever 123 and the second operating lever 124 are pulled together, and thus the first operating lever ( The lower ends of the 123 and the second operating lever 124 are rotated downward with respect to the first coupling shaft 135 and the second coupling shaft 136 to closely adhere the brake pad 126 to the circumferential side of the brake drum 121. Let's go.

When the hydraulic cylinder 128 is operated so that the upper ends of the first operating lever 123 and the second operating lever 124 are separated from each other, the lower ends of the first operating lever 123 and the second operating lever 124 are first coupled shafts. The brake pad 126 is spaced apart from the circumference of the brake drum 121 while being rotated about the 135 and the second coupling shaft 136.

On the other hand, by rotating the manual transmission switching lever 80 to rotate the manual handle 70 in a state in which the power of the geared motor 20 and the drive shaft 32 is cut off, the rotational force of the manual handle 70 is the head gear box 30 ), Since the winding drum 110 is rotated by rotating the drum drive shaft 100 through the main gear box 50, the water gate 1 is raised.

This invention has the following advantages.

First, the drum drive shaft 100 is connected to the main gear box 50, the winding drum 110 is installed on the drum driving shaft 100, and the water gate 1 is wound around the winding rope 110. It is elevated.

Therefore, as the wire rope 111 is wound around the winding drum 110, the water gate 1 is elevated, and thus the vertical installation space of the water gate winding machine is greatly reduced, and parts that protrude largely like the conventional rack bars are deleted, so as not to harm the surrounding landscape. .

Second, the coating layer 101 is formed on the drum drive shaft 100 of the present invention, the coating layer 101, chromium oxide (Cr ₂ O ₃ ) 96 ~ 98% and titanium dioxide (TiO ₂ ) 2 ~ 4% mixed Ceramic powder, chromium oxide (Cr ₂ O ₃ ) powder, aluminum oxide (Al ₂ O ₃ ) powder, titanium dioxide (TiO ₂ ) powder, yttrium oxide (Y ₂ O ₃ ) powder, zirconia (ZrO ₂ ) powder, Powder of any one type of chromium nickel (Cr ₃ C ₂ 25 NiCr) powder (chromium carbide 75%, nickel 20%, chromium 5%) is formed by spraying around the drum drive shaft (100).

Therefore, since the coating layer 101 having excellent oxidation resistance is formed around the drum drive shaft 100 which is frequently exposed to external influences, the drum drive shaft 100 is prevented from being oxidized, and safety is prevented by the oxidation of the drum drive shaft 100. Accidents are prevented and, as a result, the lifespan of the hydrolifter is extended, thereby reducing maintenance costs.

Third, an end portion of the drum drive shaft 100 at one side of the band brake 120 is provided with an overhang prevention unit 130 to prevent shaking of the drum drive shaft 100.

Therefore, when the drum drive shaft 100 is rotated or braked, the shaft support arm 131 supports the end of the drum drive shaft 100, thereby preventing the end of the drum drive shaft 100 from shaking, and the brake drum 121 may be braked. It is possible to greatly reduce the overhang generated during the operation.
