Description

Technical Field

[0001] The present invention relates to the technical field of speed reducers, in particular to a cooling tower speed reducer. Background Art

[0002] A cooling tower is a device that uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to lower the water temperature. It uses the flow of water and air to exchange heat and generate steam. The steam evaporates and takes away the heat to achieve evaporative heat dissipation, convection heat transfer and radiation heat transfer. It dissipates the waste heat generated in industry or refrigeration and air conditioning to lower the water temperature through evaporative heat dissipation to ensure the normal operation of the system. The device is generally barrel-shaped, hence the name cooling tower.

A waste oil recovery tank 71 is detachably connected to the top wall of the support plate 3.

[0031] Embodiment 1: The support plate 3 is installed on the top wall of the cooling tower 1, and the lower end of the reducer output shaft 6 is connected to the fan blade. The drive motor 7 is turned on to make the motor output shaft 8 drive the first connecting piece 55, the transmission bar 60, the second connecting piece 57, the reducer input shaft 5 and the fan blade to rotate. The rotation of the fan blade discharges the waste heat of the cooling tower 1. Under the action of the negative pressure in the cooling tower 1, the fan will rotate in the opposite direction. The reversal of the fan will bring certain hidden dangers to the personnel who repair the cooling tower 1. The setting of the one-way bearing 9 can prevent the reversal of the fan. When it is necessary to replace the lubricating oil of the reducer body 2, the cooling tower 1 and the drive motor 7 are stopped. The user pulls the handle 72 under the cooling tower 1 to pull the traction line 20 to the right to pull the first slide 19. The first slide 19 and the two second slides 22 are against each other, and the first slide 19 drives the two second slides 22 to move right, and the second slide 22 drives the magnet piece 23, the connecting bar 25, the push bar 26, and the push wheel 27 to move right, and the push wheel 27 drives the first wedge block 30 to rotate, and the first wedge block 30 rotates around the rotating shaft 31, so that one of the blocking blocks 33 is separated from the oil inlet pipe 13, and the other blocking block 33 is separated from the oil outlet pipe 15, and the old lubricating oil in the reducer body 2 flows out from the oil outlet pipe 15, and the old lubricating oil flows to the temporary storage chamber 66 of the temporary storage box 65. Since the diameter of the leakage channel 67 is very small, the speed at which the old lubricating oil passes through the leakage channel 67 is very slow, and it passes through the leakage channel 67 drop by drop, and the temporary storage chamber 66 is filled with the old lubricating oil. The old lubricating oil in the tank gradually increases, and the mass of the temporary storage box 65 increases. When the mass of the temporary storage box 65 is greater than a certain value, the gravity movable plate 64 rotates, thereby causing the gravity movable plate 64 to rotate counterclockwise, and the gravity balance member 68 moves upward. The magnetic attraction of the gravity balance member 68 causes the lower magnet sheet 23 to overcome the elastic force of the second elastic member 24 and move downward, thereby causing the second slide 22 to move downward along the connecting bar 25, and the lower second slide 22 is separated from the resistance of the first slide 19. The connecting bar 25 moves leftward along the third slide rail 70 under the elastic force of the third elastic member 28 and is reset. The rotating bar 32 is reset to a horizontal state under the elastic force of the fourth elastic member 34, and the blocking block 33 and the oil outlet pipe 15 are re-resisted to block the oil outlet pipe 15. The gravity balance member 68 pushes the slide bar 35 and the second wedge block 36 to overcome the elastic force of the fifth elastic member 37 and move upward, so that the second wedge block 36 pushes the third wedge block 45 and the oil stop plate 43 to overcome the elastic force of the sixth elastic member 431 and move left, so that the plate hole 44 and the refueling channel 41 are connected, and the new lubricating oil in the oil storage chamber 39 flows out from the refueling channel 41 to the first guide bucket 14, and is drained to the oil inlet pipe 13 through the first guide bucket 14 and enters the reducer body 2. The liquid level in the oil storage chamber 39 will gradually decrease, and the floating liquid level indicator 47 will move downward as the liquid level decreases. The floating liquid level indicator 47 is aligned with the scale on the glass window 46. The user can observe the scale pointed to by the floating liquid level indicator 47 under the cooling tower 1 to judge how much lubricating oil is added.

[0032] When it is necessary to stop adding lubricating oil, the user releases the handle 72, and the first slide 19 is reset to the left along the second slide rail 69 under the elastic force of the first elastic member 18. The upper movable blocking mechanism is reset under the elastic force of the third elastic member 28 and the fourth elastic member 34, and the upper blocking block 33 blocks the oil inlet pipe 13 again to prevent impurities from entering the reducer body 2 from the oil inlet pipe 13 and affecting the lubrication effect. When the old lubricating oil in the temporary storage chamber 66 gradually flows into the waste oil recovery tank 71 from the leakage channel 67, the mass of the temporary storage box 65 gradually decreases. When the mass of the temporary storage box 65 is less than a certain value, the gravity activity Under the action of gravity of the movable plate 64, the gravity movable plate 64 reverses and resets, the gravity balance member 68 moves downward, and the magnet piece 23 loses its magnetic attraction and moves upward and reset under the elastic force of the second elastic member 24. The second slide 22 moves upward and resets to the right of the first slide 19. After the slide rod 35 loses the supporting force of the gravity balance member 68, the second wedge block 36 and the slide rod 35 move downward and reset under the elastic force of the fifth elastic member 37. After the third wedge block 45 loses the thrust of the second wedge block 36, the oil stop plate 43 moves right and resets under the elastic force of the sixth elastic member 431, and the refueling channel 41 is re-blocked to stop refueling.

[0033] In this embodiment, the lubricating oil in the reducer body 2 can be replaced by pulling the traction line 20 under the cooling tower 1, and the oil inlet pipe 13 and the oil outlet pipe 15 are automatically connected and blocked at the appropriate time, so that the oil filling and draining operations are cleverly realized. The user does not need to climb up the higher cooling tower 1 and manually unscrew the cover and perform a series of tedious operations to replace the lubricating oil. The linkage is high and the design is reasonable.

[0034] According to an optional embodiment of the present invention, a heat dissipation fan 51 is provided on the front wall of the reducer body 2 , a fan dustproof net 52 is provided on the heat dissipation fan 51 , and a cleaning mechanism is provided on the reducer body 2 .

[0035] According to an optional embodiment of the present invention, the cleaning mechanism includes a transmission rod 48, a cleaning strip 49 and a first slide rail 50. The first slide rail 50 is fixed to the front wall of the reducer body 2. One end of the transmission rod 48 is fixed to the cleaning strip 49. The other end of the cleaning strip 49 is fixed to the first slide 19. The cleaning strip 49 is slidably connected to the first slide rail 50. The rear wall of the cleaning strip 49 is provided with bristles, and the bristles are against the fan dust net 52.

[0036] According to an optional embodiment of the present invention, an extension bar 53 is fixed to the cleaning bar 49, and a magnet block 54 is fixed to the top wall of the extension bar 53. The lower end of the motor output shaft 8 is fixed to a first connecting piece 55, and the bottom wall of the first connecting piece 55 is provided with two or more connecting grooves 56. The upper end of the reducer input shaft 5 is fixed to a second connecting piece 57, and the second connecting piece 57 is provided with two or more through holes 58. A magnet ring 59 is slidably connected to the reducer input shaft 5, and the top wall of the magnet ring 59 is connected to the bottom wall of the second connecting piece 57 through a seventh elastic member 61. The top wall of the magnet ring 59 is fixed to two or more transmission bars 60, and the transmission bar 60 is slidably connected to the inner wall of the through hole 58, and the transmission bar 60 extends into one of the connecting grooves 56.

[0037] According to an optional embodiment of the present invention, a glass window 46 is inlaid on the side wall of the oil storage tank 11, and a scale is provided on the glass window 46. A floating liquid level indicator 47 is slidably connected to the rear wall of the oil storage cavity 39.

[0038] According to an optional embodiment of the present invention, the front wall of the fixed plate 38 is fixed with a second slide rail 69 and two third slide rails 70, the first slide 19 is slidably connected to the second slide rail 69, and the two connecting bars 25 are respectively slidably connected to the two third slide rails 70.

[0039] According to an optional embodiment of the present invention, a handle 72 is fixedly connected to one end of the pulling line 20 .

[0040] According to an optional embodiment of the present invention, the inner diameter of the liquid leakage channel 67 gradually decreases from top to bottom, and the liquid leakage channel 67 is located on the left side of the left wall of the gravity movable plate 64. Example

[0041] Since the oil temperature of the cooling tower 1 gradually rises during operation, a heat dissipation fan 51 is provided on the reducer body 2 to cool the reducer body 2 to prevent the excessive oil temperature from affecting the operation of the reducer body 2. The heat dissipation fan 51 is provided with a fan dust screen 52 for dust prevention. When the user pulls the handle 72 to replace the lubricating oil, the first slide 19 moves rightward, driving the transmission rod 48, the cleaning bar 49, the extension bar 53, and the magnet block 54 to move rightward, so that the bristles on the cleaning bar 49 clean and wipe the fan dust screen 52, sweeping away dust on the fan dust screen 52 to prevent dust from affecting the heat dissipation effect.

[0042] When the fan is installed and repaired, the drive motor 7 will be rotated forward and reverse to debug the drive motor 7. However, due to the presence of the one-way bearing 9, the drive motor 7 cannot rotate forward and reverse. Therefore, when the magnet block 54 moves to the right, the magnetic attraction of the magnet block 54 causes the magnet ring 59 to overcome the elastic force of the seventh elastic member 61 and move downward, so that all the transmission bars 60 are separated from the connecting groove 56, and the first connecting piece 55 and the magnet ring 59 are disconnected. The user can then debug the drive motor 7 forward and reverse while changing the lubricating oil. One person pulls the handle 72, and the other person performs the operation on the cooling tower 1. The drive motor 7 is debugged to improve the detection efficiency. After the debugging is completed, the drive motor 7 is turned off. After the lubricating oil is replaced, the handle 72 is released. The transmission rod 48 drives the cleaning bar 49, the extension bar 53, and the magnet block 54 to move to the left and reset. The magnet ring 59 moves up and reset under the elastic force of the seventh elastic member 61. The transmission bar 60 and the bottom wall of the first connecting piece 55 are against each other. When the motor output shaft 8 rotates again, the connecting groove 56 is aligned with the transmission bar 60. The transmission bar 60 will be inserted into the connecting groove 56 under the elastic force of the seventh elastic member 61, thereby completing the connection between the first connecting piece 55 and the magnet ring 59.
