Description

Technical Field

[0001] The present invention relates to the technical field of hoisting equipment, and more specifically, to an ultra-long steam turbine generator hoisting equipment. Background Technique

[0002] Hoisting refers to the general term for the installation and positioning of equipment by a crane or a hoisting mechanism. During the overhaul or repair process, various hoisting tools are used to lift equipment, workpieces, utensils, materials, etc., causing their positions to change. With the continuous development of industrial technology, the size and weight of steam turbine generators are constantly increasing, and the requirements for hoisting equipment are also getting higher and higher. The hoisting method is to install the rotor into the motor housing;

[0003] However, in most ports in coastal areas, tower cranes are used to hoist goods. The working mechanism of a tower crane consists of four parts: hoisting, luffing, slewing, and traveling. The electrical system includes motors, controllers, distribution boxes, connecting lines, signal and lighting devices, etc. Among them, a low-voltage system often forms in coastal areas. The easterly strong winds in the front of the low-voltage system, the southerly strong winds in the middle, or the northerly strong winds in the rear may all cause the wind force in coastal areas to increase. When working during this period, tower crane operators often encounter problems of poor stability and poor safety in strong wind weather or other complex hoisting environments;

[0004] In view of this, we propose an ultra-long steam turbine generator hoisting equipment. Summary of the Invention

[0005] The purpose of the present invention is to provide an ultra-long steam turbine generator hoisting equipment to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the present invention provides an ultra-long steam turbine generator hoisting equipment, including a protective shell and a stabilizing device. Inside the protective shell, there is a wind direction component for detecting the wind direction. Inside the wind direction component, there is a touch sensor for detecting the magnitude of the wind direction. Inside the wind direction component, there is a wind direction rod for wind direction guidance. At the top of the wind direction component, there is a stabilizing device for steering stability. At the top of the stabilizing device, there is a rotating shaft. Inside the stabilizing device, there is a stabilizing member for stabilizing the rotating shaft in strong wind weather, where:

[0007] Through the rotation of the wind direction component, the wind direction and wind speed are monitored by using the wind direction rod and the touch sensor, and at the same time, the tower crane conveying rod is stabilized by using the stabilizing device and the stabilizing member.

[0008] Preferably, a locking chamber is fixedly connected to the top of the protective shell. A plurality of square holes are opened on the outer wall of the locking chamber. A wind direction component is arranged inside the protective shell, a stabilizing device is arranged inside the locking chamber, and the rotating shaft is arranged at the top of the stabilizing device.

[0009] Preferably in the present invention, the wind direction assembly includes a side plate. An inner wall of the side plate is fixedly connected with a fixing plate. One end of a rotating rod is rotatably connected to an inner side of the fixing plate. The other end of the rotating rod is fixedly connected with a first bevel gear. Both sides of a middle end of the rotating rod are fixedly connected with wind direction rods. Both sides of the fixing plate are fixedly connected with first fixing columns. Inner sides of both sides of the first fixing columns are fixedly connected with touch sensors.

[0010] Preferably in the present invention, one side of the first bevel gear is meshed and connected with a second bevel gear. The top of the second bevel gear is fixedly connected with a rotating column. The rotating column is fixedly connected with a turntable through a column. A second fixing column is arranged between the rotating column and the turntable. The second fixing column is fixedly connected to an inner wall of the protective shell through multiple columns.

[0011] Preferably in the present invention, the first bevel gear is provided with one - quarter serrations. The second bevel gear is a complete gear. Multiple first bevel gears are arranged around the second bevel gear. And the rotating rod is connected to the first bevel gear through penetrating the protective shell.

[0012] Preferably in the present invention, the stabilizing device includes a threaded screw rod. One end of the threaded screw rod is rotatably connected to the turntable. The other end of the threaded screw rod is telescopically connected to one end of a telescopic rod. Outer walls of the other ends of the telescopic rods are fixedly connected with one ends of multiple first extension rods. The other ends of the first extension rods are rotatably connected to a bent rod.

[0013] Preferably in the present invention, the stabilizing device includes a sliding member. The sliding member is slidably connected to an outer wall of the threaded screw rod. Outer walls of upper ends of the sliding member are fixedly connected with one ends of multiple second extension rods. The other ends of the second extension rods are rotatably connected to one end of a connecting rod. The other end of the connecting rod is rotatably connected to one end of the bent rod.

[0014] Preferably in the present invention, the bent rod is integrally composed of a long rod and a short rod. And the long rod and the short rod are fixedly connected at an acute - angle. One end of the first extension rod is rotatably connected to a connection part of the long rod and the short rod. One end of the connecting rod is rotatably connected to the other end of the short rod. The included angle between the long rod and the short rod is acute.

[0015] Preferably in the present invention, the long rod is fixedly connected with a buckle member at an end far from the first extension rod. A middle end of the top of the long rod is fixedly connected with a blocking plate. A stabilizing member is fixedly connected between the blocking plate and the buckle member. The top of the stabilizing member is fixedly connected with a rubber pad.

[0016] Preferably in the present invention, the outer wall of the rubber pad is arc-shaped, and an annular groove is formed on the outer wall of the rotating shaft. The shape of the annular groove fits the state where multiple rubber pads are closed into a ring. When the wind speed is relatively high and the rubber pads are closed to the maximum extent, they will fit with the annular groove of the rotating shaft and closely adhere to the annular groove.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] 1. In this ultra-long turbogenerator hoisting device, when the wind blows the wind direction assembly, the wind direction rod tilts, the rotating rod rotates by a certain angle and drives the first bevel gear to rotate. By presetting the distance between the two first fixed columns on both sides, the threshold value that the wind speed can withstand is determined. When the outer wall of the wind direction rod touches the touch sensor, when the touch sensor is squeezed, it is the threshold value of the wind speed that can be withstood, and an alarm will be issued to the operator for early warning.

[0019] 2. In this ultra-long turbogenerator hoisting device, the first bevel gear drives the second bevel gear, the turntable and the threaded screw rod to rotate. The rotation of the threaded screw rod drives the sliding part to slide upward, and at the same time drives the second extension rod to move upward. The second extension rod will then push the bending rod to rotate upward. At this time, the stabilizing part and the rubber pads contract and close together to clamp the rotating shaft. During the rotation of the rotating shaft, it will continuously be affected by the blocking and frictional force of the rubber pads, making the rotation process more stable.

Embodiment 1

[0032] Please refer to Figures 1-7As shown in the figure, this embodiment provides a hoisting device for an ultra-long steam turbine generator, including a protective shell 1 and a stabilizing device 4. Inside the protective shell 1, there is a wind direction component 3 for detecting the wind direction. Inside the wind direction component 3, there is a touch sensor 331 for detecting the magnitude of the wind direction. Inside the wind direction component 3, there is a wind direction rod 322 for wind direction guidance. At the top of the wind direction component 3, there is a stabilizing device 4 for steering stability. At the top of the stabilizing device 4, there is a rotating shaft 5. Inside the stabilizing device 4, there is a stabilizing member 45 for stabilizing the rotating shaft 5 in strong wind weather. Among them: Through the rotation of the wind direction component 3, the wind direction and wind speed are monitored by using the wind direction rod 322 and the touch sensor 331. At the same time, the tower crane conveying rod is stabilized by using the stabilizing device 4 and the stabilizing member 45.

[0033] At the top of the protective shell 1, there is a locking chamber 2 fixedly connected. On the outer wall of the locking chamber 2, there are a plurality of square holes 21. Inside the protective shell 1, there is a wind direction component 3. Inside the locking chamber 2, there is a stabilizing device 4. The rotating shaft 5 is arranged at the top of the stabilizing device 4.

[0034] The wind direction component 3 includes side plates 31. On the inner wall of the side plates 31, there is a fixed plate 32 fixedly connected. One end of a rotating rod 321 is rotatably connected to the inner side of the fixed plate 32. The other end of the rotating rod 321 is fixedly connected with a first bevel gear 323. On both sides of the middle end of the rotating rod 321, there are wind direction rods 322 fixedly connected. On both sides of the fixed plate 32, there are first fixing columns 33 fixedly connected. Inside the two first fixing columns 33, there is a touch sensor 331 fixedly connected. When the wind speed is relatively low, the rotation angle of the wind direction rod 322 is small and it will not touch the first fixing column 33. At this time, when the wind direction rod 322 rotates, it will drive the rotating rod 321 to rotate and at the same time drive the first bevel gear 323 to rotate. At the same time, when the first bevel gear 323 rotates, it will drive the second bevel gear 34 to rotate.

[0035] One side of the first bevel gear 323 is meshed with a second bevel gear 34. At the top of the second bevel gear 34, there is a rotating column 35 fixedly connected. The rotating column 35 is fixedly connected with a turntable 361 through a column. Between the rotating column 35 and the turntable 361, there is a second fixing column 36. The second fixing column 36 is fixedly connected to the inner wall of the protective shell 1 through multiple columns. The rotation of the second bevel gear 34 will drive the rotating column 35 and the turntable 361 to rotate.

[0036] A quarter of sawteeth are provided on the first helical gear 323. The second helical gear 34 is a complete gear. A plurality of first helical gears 323 are arranged around the second helical gear 34. The rotating rod 321 is connected to the first helical gear 323 through the protective housing 1. The stabilizing device 4 includes a threaded lead screw 41. One end of the threaded lead screw 41 is rotatably connected to the turntable 361. The other end of the threaded lead screw 41 is telescopically connected to one end of the telescopic rod 411. The outer wall of the other end of the telescopic rod 411 is fixedly connected to one end of a plurality of first extension rods 412. The other end of the first extension rod 412 is rotatably connected to the bent rod 44.

[0037] The stabilizing device 4 includes a sliding member 42. The sliding member 42 is slidably connected to the outer wall of the threaded lead screw 41. The upper outer wall of the sliding member 42 is fixedly connected to one end of a plurality of second extension rods 421. The other end of the second extension rod 421 is rotatably connected to one end of the connecting rod 43. The other end of the connecting rod 43 is rotatably connected to one end of the bent rod 44.

[0038] It can be seen that during the operation of the tower crane, when the wind speed is too fast at high altitude, the strong wind blows the wind direction assembly 3, causing the wind direction rod 322 to tilt. During the tilting process of the wind direction rod 322, it will drive the rotating rod 321 to rotate a certain angle. At the same time, the rotating rod 321 will drive the first helical gear 323 to rotate. The external rack of the first helical gear 323 rotates a certain angle together with the wind direction rod 322. When the first helical gear 323 rotates to the edge position of the rack, it will no longer drive the second helical gear 34 to rotate. At the same time, the distance between the two first fixed columns 33 can be set in advance to determine the threshold value that the wind speed can withstand. When the outer wall of the wind direction rod 322 touches the touch sensor 331, when the touch sensor 331 is squeezed, it is the threshold value of the wind speed that can be withstood, and an alarm will be issued to the operator for early warning.

[0039] During the installation of the tower crane, as the installation height of the tower crane increases, the wind speed will also become faster and the force on the wind direction rod 322 will also increase continuously. Therefore, during the process of continuous height increase, the staff also needs to continuously adjust the position between the first fixed columns 33 through the control terminal to ensure the safety of the operator and surrounding objects. Embodiment 2

[0040] Different from Embodiment 1, in order to achieve the stability of the operator during turning, such as Figures 5-7As shown, the bent rod 44 as a whole is composed of a long rod 441 and a short rod 442, and the long rod 441 and the short rod 442 are fixedly connected at an acute angle. One end of the first extension rod 412 is rotatably connected to the connection part of the long rod 441 and the short rod 442. One end of the connecting rod 43 is rotatably connected to the other end of the short rod 442. A buckle 4411 is fixedly connected to the end of the long rod 441 away from the first extension rod 412. A blocking plate 4412 is fixedly connected to the middle of the top of the long rod 441. A stabilizing member 45 is fixedly connected between the blocking plate 4412 and the buckle 4411. A rubber pad 451 is fixedly connected to the top of the stabilizing member 45. The outer wall of the rubber pad 451 is arc-shaped. An annular groove is formed on the outer wall of the rotating shaft 5, and the shape of the annular groove fits the state in which a plurality of rubber pads 451 are closed into a ring.

[0041] It can be seen from this that when the first helical gear 323 drives the second helical gear 34 to rotate, it also drives the turntable 361 and the threaded rod 41 to rotate. During the rotation of the threaded rod 41, it will drive the sliding member 42 to slide upward, and at the same time drive the second extension rod 421 to move upward. At this time, the second extension rod 421 pushes the connecting rod 43 and pushes the bent rod 44 to rotate upward. At this time, the bent rod 44 rotates from the horizontal position to the vertical position. At this time, the stabilizing member 45 and the rubber pad 451 fixed on the long rod 441 gradually contract and close together, clamping the rotating shaft 5. During the rotation of the rotating shaft 5, greater friction can be applied, and the shape of the inner side of the annular groove of the rotating shaft 5 fits the shape of the closed rubber pads 451. At this time, the rotating shaft 5 will be continuously blocked and affected by the friction of the rubber pads 451 during the rotation process, making the rotation process more stable.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present invention and do not limit the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
