Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of motor hoisting tooling, in particular to a converter station cooling tower motor hoisting tooling. BACKGROUND

[0002] In the operation of the cooling tower, the special motor of the cooling tower has a relatively large margin, which is a relatively common problem. The special motor of the cooling tower often operates under high-speed running and low-load conditions, resulting in very strong noise and a very poor working environment, so regular manual maintenance is required.

[0003] During maintenance, due to the poor working environment inside the cooling tower and the heavy weight of the motor, the motor is generally hoisted out of the cooling tower for maintenance and replacement using a hoisting tooling. The traditional hoisting tooling is prone to pendulum-type swinging of the hinge and the lowermost motor during hoisting, which is likely to collide with surrounding equipment. At the same time, the swinging increases the stress on the hinge, which also increases the risk of hinge fracture. In addition, there is no protection mechanism below the motor during hoisting. When the hinge breaks, the motor falls to the lower side, which is likely to injure the construction personnel. SUMMARY

[0004] Therefore, the main purpose of the present application is to provide a converter station cooling tower motor hoisting tooling, which solves the technical problem of the traditional hoisting tooling, which is prone to pendulum-type swinging of the hinge and the lowermost motor during hoisting, which is likely to collide with surrounding equipment.

[0021] Furthermore, to better illustrate this disclosure, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this disclosure can be practiced without certain specific details. In some instances, methods, means, components, and circuits well-known to those skilled in the art are not described in detail to highlight the main points of this disclosure. To better understand the above technical solutions, the following will provide a detailed description of the above technical solutions in conjunction with the accompanying drawings and specific embodiments.

[0022] like Figures 1-8 As shown, the present invention provides a hoisting fixture for a converter station cooling tower motor, comprising: Horizontal frame 13; A hoisting assembly 3 is slidably connected to the cross frame 13; The hoisting assembly 3 includes a sliding unit 31, a winding unit 32, a protective cylinder 33, a hook 34, a slide groove 36, a slider 37, and a hinge 38. The sliding unit 31 is slidably connected to the crossbeam 13. The lower end of the sliding unit 31 is fixedly connected to the winding unit 32. The hinge 38 is nested inside the winding unit 32. One end of the hinge 38 extends out from the winding unit 32 and is fixedly connected to the hook 34. The protective cylinder 33 is nested on the hinge 38. The protective cylinder 33 is multi-sectioned and the multiple sections of the protective cylinder 33 are slidably connected. The slider 37 is fixedly connected to the outer wall of the upper end of the protective cylinder 33. The slider 37 is slidably connected to the slide groove 36. The slide groove 36 is formed on the inner wall of the protective cylinder 33. The uppermost end of the multiple sections of the protective cylinder 33 is fixedly connected to the winding unit 32, and the lowermost end of the multiple sections of the protective cylinder 33 abuts against the hook 34.

[0023] In this embodiment, during hoisting, the user first controls the sliding unit 31 via the controller (remotely operated, not shown in the figure) to slide it directly above the motor. Then, the user controls the winding unit 32 to release the hinge 38. As the hinge 38 moves downward, the hook 34 no longer abuts against the lower end of the multi-section protective cylinder 33. Therefore, the multi-section protective cylinder 33 begins to slide downward and elongate due to gravity. The slider 37 slides downward in the groove 36. Because the length of the multi-section protective cylinder 33 is greater than the length of the hinge 38, the hinge 38 is always wrapped by the protective cylinder 33 during hoisting. After the hook 34 and the motor are fixed, the motor needs to be hoisted out of the cooling tower because it is in the cooling tower. Therefore, the user controls the winding unit 32 to wind up the hinge 38. When the hinge 38 is wound and shortened, the hook 34 exerts an upward pushing force on the lower end of the multi-section protective cylinder 33. At this time, the slider 37 slides upward in the groove 36. The multi-section protective cylinder 33 retracts with the length of the hinge 38. Then, the sliding unit 31 drives the whole unit to move left and right to the appropriate position.

[0024] It is important to understand that the protective sleeve 33 nested on the hinge 38 can prevent the motor from causing the hinge 38 to sway during the hoisting process. Because the upper end of the protective sleeve 33 is fixedly connected to the winding unit 32, the extended protective sleeve 33 is similar to a long tube, which can prevent the hinge 38 from swaying during the hoisting process. Swaying will increase the tension of the hinge 38, which may cause the hinge 38 to break and cause danger. At the same time, excessive swaying will cause the hoisting motor to hit surrounding objects.

[0025] Specifically, the frame assembly 1 includes a base 11, a bracket 12, and a crossbar 13; two symmetrical brackets 12 are fixedly connected to the base 11, with the upper ends of the two brackets 12 fixedly connected and the lower ends fixedly connected to the base 11, forming a triangle; the top of each bracket 12 is fixedly connected to the crossbar 13. The moving component 2 includes a traveling wheel 21, a handle 22, a grooving tooth 23, a toothed groove 24, a connecting strip 25, a support spring 26, a brake pin 27, and a brake pad 28. The handle 22 is rotatably connected to the base 11. The grooving tooth 23 is fixedly connected to the lower end of the handle 22. The grooving tooth 23 and the toothed groove 24 are adapted to each other. The toothed groove 24 is formed on the base 11. The lower end of the handle 22 extends into the base 11 and abuts against the connecting strip 25. The connecting strip 25 is inside the base 11. The brake pin 27 is fixedly connected to both ends of the connecting strip 25. The support spring 26 is nested on the brake pin 27. The upper end of the support spring 26 is fixedly connected to the connecting strip 25, and the lower end of the support spring 26 is fixedly connected to the base 11. The brake pin 27 extends out of the base 11 and is fixedly connected to the brake pad 28. The brake pad 28 is above the traveling wheel 21. The traveling wheel 21 is fixedly connected to both ends of the base 11.

[0026] In this embodiment, the user can first move the entire fixture above the motor to be hoisted. Once in position, the user can turn the handle 22. The turn of the handle 22 pushes the connecting bar 25. When the connecting bar 25 moves downward, it causes the brake pin 27 to move downward, compressing the support spring 26. Finally, the brake pin 27 causes the brake pad 28 to come into contact with the traveling wheel 21. At this time, the traveling wheel 21 cannot rotate, and the entire device is fixed. Hoisting can then be performed. After hoisting is completed, the user turns the handle 22 in the opposite direction. When the handle 22 moves upward, the pressure on the connecting bar 25 gradually decreases. During this process, the support spring 26 slowly extends, causing the connecting bar 25 and the brake pin 27 to move upward. The brake pin 27 causes the brake pad 28 to leave the traveling wheel 21. At this time, the traveling wheel 21 is no longer constrained, and the user can move the device again.

[0027] Specifically, the inflation assembly 4 includes a piston tube 41, a push rod 42, a rubber piston 43, a deformation spring 44, and an air guide tube 45; the piston tube 41 is fixedly connected to both ends of the cross frame 13, the rubber piston 43 is slidably connected inside the piston tube 41, the push rod 42 is fixedly connected to one side of the rubber piston 43, the push rod 42 extends out of the piston tube 41, the top end of the push rod 42 faces the sliding unit 31, the deformation spring 44 is fixedly connected to the other side of the rubber piston 43, the deformation spring 44 is fixedly connected to the bottom of the piston tube 41, and the air guide tube 45 is fixedly connected to the bottom outer wall of the piston tube 41; The protective component 5 includes a support plate 51, an air collection tank 53, a hinge 55, a limiting block 56, a sliding block 510, and an inflatable telescopic column 57. The support plate 51 is hinged to the sliding block 510 via the hinge 55. The limiting block 56 is located below the support plate 51 and is fixedly connected to the sliding block 510. The inflatable telescopic column 57 is fixedly connected to the support plate 51 near the sliding block 510, and the air collection tank is fixedly connected to the inflatable telescopic column 57. The gas collection tank 53 and the sliding block 510 are fixedly connected. The gas collection tank 53 is fixedly connected to the gas guide pipe 45. The protection component 5 also includes a through hole 52, a guide rod 58 and a telescopic spring 59. The through hole 52 is opened on the sliding block 510. The guide rod 58 passes through the through hole 52. The guide rod 58 and the sliding block 510 are slidably connected. The telescopic spring 59 is nested on the guide rod 58 and is located below the sliding block 510.

[0028] In this embodiment, when the sliding unit 31 slides left or right in the crossbar 13, it pushes the push rod 42. The push rod 42 drives the rubber piston 43 to move closer to the air guide tube 45, compressing the gas in the piston tube 41 into the air guide tube 45. At the same time, the deformation spring 44 is compressed by the rubber piston 43. The gas enters the gas collection tank 53 from the air guide tube 45, and then enters the inflatable telescopic column 57 from the gas collection tank 53. The inflatable telescopic column 57 is filled with gas and extends because one end of the inflatable telescopic column 57 is... The air collection tank 53 is fixedly connected to the sliding block 510. Therefore, when the inflatable telescopic column 57 extends, it will cause the support plate 51 to rotate around the hinge 55. Finally, the inflatable telescopic column 57 extends to its maximum length, and at the same time, the support plate 51 and the sliding block 510 are at a 90-degree angle. At this time, the hook 34 and the motor are above the support plate 51. Then, the user operates the controller to release the hinge 38 from the winding unit 32. The hinge 38 extends, causing the hook 34 and the motor to contact the support plate 51. After the support plate 51 is subjected to pressure, The sliding block 510 will compress the telescopic spring 59 downwards, while the bearing plate 51 in the guide rod 58 drives the motor to slide downwards until it reaches a position that the user can reach. Then the user can directly repair the motor on the bearing plate 51, or remove the motor. After removing the motor, the user can operate the controller to make the winding unit 32 wind up the hinge 38. After the bearing plate 51 is no longer under pressure, the telescopic spring 59 extends and drives the bearing plate 51 to slide upwards and reset. Then the user can operate the controller to make the sliding unit 31 drive the hoisting assembly 3 to slide to the middle of the cross frame 13. The sliding unit 31 no longer squeezes the push rod 42, and the deformation spring 44 is no longer under the pressure of the rubber piston 43. The deformation spring 44 extends and drives the rubber piston 43 to slide away from the air pipe 45, drawing the gas from the gas collection tank 53 and the inflatable telescopic column 57 into the piston pipe 41. After being sucked in, the inflatable telescopic column 57 shortens and pulls up the bearing plate 51. At this time, the bearing plate 51 and the sliding block 510 are parallel, and the bearing plate 51 is retracted.

[0029] In use, the user first moves the entire fixture above the motor to be hoisted. Once in position, the user rotates handle 22, which pushes connecting bar 25 downwards. As connecting bar 25 moves downwards, it causes brake pin 27 to move downwards, compressing support spring 26. Finally, brake pin 27 causes brake pad 28 to contact with traveling wheel 21, preventing traveling wheel 21 from rotating and fixing the entire device in place. Hoisting can then proceed. During hoisting, the user first controls the sliding unit 31 via the controller (remote operation, not shown in the figure) to slide it directly above the motor. Then, the user controls the winding unit 32 to release hinge 38. As hinge 38 moves downwards, hook 34 no longer contacts the lower end of multi-section protective cylinder 33, thus allowing the multi-section protective cylinder to be hoisted. As the multi-section protective cylinder 33 begins to slide downwards and elongates due to gravity, the slider 37 slides downwards in the groove 36. Because the length of the multi-section protective cylinder 33 is greater than the length of the hinge 38, the hinge 38 is always wrapped by the protective cylinder 33 during final hoisting. After the hook 34 and the motor are fixed, since the motor is in the cooling tower, it needs to be hoisted out of the cooling tower. Therefore, the user controls the winding unit 32 to wind up the hinge 38. When the hinge 38 is winding and shortening, the hook 34 exerts an upward pushing force on the lower end of the multi-section protective cylinder 33. At this time, the slider 37 slides upwards in the groove 36, and the multi-section protective cylinder 33 retracts with the length of the hinge 38. Subsequently, the sliding unit 31 drives the entire assembly to move left and right to the appropriate position. The protective cylinder 33 nested on the hinge 38 can prevent damage during hoisting. The motor drives the hinge 38 to sway. Because the upper end of the protective cylinder 33 is fixedly connected to the winding unit 32, the extended protective cylinder 33 resembles a long tube, which can prevent the hinge 38 from swaying during hoisting. Swaying increases the tension of the hinge 38, which may cause the hinge 38 to break and cause danger. At the same time, excessive swaying may cause the hoisting motor to collide with surrounding objects. When the sliding unit 31 slides to the left or right in the crossbeam 13, it pushes the push rod 42. The push rod 42 drives the rubber piston 43 to move closer to the air guide pipe 45, compressing the gas in the piston pipe 41 into the air guide pipe 45. At the same time, the deformation spring 44 is compressed by the rubber piston 43. The gas enters the gas collection tank 53 from the air guide pipe 45, and then enters the inflatable telescopic column 57 from the gas collection tank 53. The inflatable telescopic column 57 is inflated and extends. Because one end of the inflatable telescopic column 57 is fixedly connected to the sliding block 510 by the air collection tank 53, when the inflatable telescopic column 57 extends, it will drive the support plate 51 to rotate around the hinge 55. Finally, the inflatable telescopic column 57 extends to its maximum length, and at the same time, the support plate 51 and the sliding block 510 are at a 90-degree angle. At this time, the hook 34 and the motor are above the support plate 51. Then, the user operates the controller to release the hinge 38 from the winding unit 32. The hinge 38 extends, causing the hook 34 and the motor to contact the support plate 51. After the support plate 51 is under pressure, it will drive the sliding block 510 to compress the telescopic spring 59 downward. At the same time, the support plate 51 drives the motor to slide downward in the guide rod 58, finally reaching the position that the user can reach.The user can then directly repair the motor on the support plate 51, or remove the motor. After removing the motor, the user can operate the controller to make the winding unit 32 wind up the hinge 38. After the support plate 51 is no longer under pressure, the telescopic spring 59 extends and drives the support plate 51 to slide upward and reset. Then, the user can operate the controller to make the sliding unit 31 drive the hoisting assembly 3 to slide to the middle of the crossbeam 13. The sliding unit 31 no longer squeezes the push rod 42, and the deformation spring 44 is no longer under the pressure of the rubber piston 43. The deformation spring 44 extends and drives the rubber piston 43 to slide away from the air guide tube 45, drawing the gas from the air collection tank 53 and the inflatable telescopic column 57 into the piston tube 41. After being drawn in, the inflatable telescopic column 57 shortens, and the inflatable telescopic column 57 expands. Column 57 pulls up the support plate 51, at which point the support plate 51 and sliding block 510 are parallel. The support plate 51 is retracted, and the support plate 51 below the motor provides protection. During hoisting, if hinge 38 breaks, the motor will fall onto the support plate 51. After being buffered by the telescopic spring 59, the support plate 51 slowly lowers with the motor, preventing injury to people below. After hoisting, the user rotates handle 22 in the opposite direction. As handle 22 moves upward, the pressure on connecting bar 25 gradually decreases. During this process, support spring 26 slowly extends, causing connecting bar 25 and brake column 27 to move upward. Brake column 27 causes brake pad 28 to disengage from traveling wheel 21. At this point, traveling wheel 21 is unrestrained, and the user can move the device again.
