Description

Technical Field

[0001] The invention relates to the technical field of hoisting equipment, in particular to a super-long steam turbine generator hoisting equipment. Background Art

[0002] Hoisting refers to the installation and positioning of equipment by cranes or lifting mechanisms. During the inspection or maintenance process, various hoisting machines are used to lift equipment, workpieces, tools, materials, etc. to change their positions. With the continuous development of industrial technology, the size and weight of steam turbine generators are increasing, and the requirements for hoisting equipment are getting higher and higher. The hoisting method is to install the rotor into the motor housing; However, most ports in coastal areas use tower cranes to lift cargoes. The working mechanism of the tower crane consists of four parts: lifting, luffing, slewing and walking. The electrical system includes motors, controllers, distribution boxes, connecting lines, signals and lighting devices, etc. Among them, low-voltage systems are often formed in coastal areas. Strong easterly winds in the front of the low pressure, strong southerly winds in the middle, or strong northerly winds in the back may cause increased wind in coastal areas. When working during this period, tower crane operators often encounter strong winds or other complex lifting environments, which will lead to poor stability and safety. In view of this, we propose an ultra-long steam turbine generator lifting equipment. Summary of the invention

Embodiment 1

[0019] See also Figure 1-7 As shown, this embodiment provides an extra-long steam turbine generator hoisting device, including a protective shell 1 and a stabilizing device 4, a wind direction component 3 for detecting wind direction is arranged on the inner side of the protective shell 1, a touch sensor 331 for detecting the magnitude of the wind direction is arranged in the wind direction component 3, a wind direction rod 322 for wind direction guidance is arranged in the wind direction component 3, a stabilizing device 4 for steering stability is arranged on the top of the wind direction component 3, a rotating shaft 5 is arranged on the top of the stabilizing device 4, and a stabilizing member 45 for stabilizing the rotating shaft 5 in windy weather is arranged in the stabilizing device 4, wherein: through the rotation of the wind direction component 3, the wind direction rod 322 and the touch sensor 331 are used to monitor the wind direction and wind speed, and at the same time, the stabilizing device 4 and the stabilizing member 45 are used to stabilize the tower crane conveying rod.

[0020] The top of the protective shell 1 is fixedly connected with a locking chamber 2, the outer wall of the locking chamber 2 is provided with a plurality of square holes 21, a wind direction assembly 3 is arranged in the protective shell 1, a stabilizing device 4 is arranged in the locking chamber 2, and a rotating shaft 5 is arranged at the top of the stabilizing device 4.

[0021] The wind direction assembly 3 includes a side plate 31, the inner wall of the side plate 31 is fixedly connected to a fixing plate 32, the inner side of the fixing plate 32 is rotatably connected to one end of a rotating rod 321, the other end of the rotating rod 321 is fixedly connected to a No. 1 bevel gear 323, the middle end of the rotating rod 321 is fixedly connected to wind direction rod 322 on both sides, the two sides of the fixing plate 32 are fixedly connected to a No. 1 fixing column 33, the inner sides of the No. 1 fixing columns 33 on both sides are fixedly connected to touch sensors 331, when the wind speed is low, the rotation angle of the wind direction rod 322 is small and does not touch the No. 1 fixing column 33, at this time, the rotation of the wind direction rod 322 drives the rotating rod 321 to rotate, and at the same time drives the No. 1 bevel gear 323 to rotate, and at the same time, the No. 1 bevel gear 323 drives the No. 2 bevel gear 34 to rotate during the rotation process.

[0022] One side of the No. 1 bevel gear 323 is meshedly connected with the No. 2 bevel gear 34, the top of the No. 2 bevel gear 34 is fixedly connected with a rotating column 35, the rotating column 35 is fixedly connected to the turntable 361 through a column, a No. 2 fixed column 36 is arranged between the rotating column 35 and the turntable 361, and the No. 2 fixed column 36 is fixedly connected to the inner wall of the protective shell 1 through multiple columns, and the rotation of the No. 2 bevel gear 34 will drive the rotating column 35 and the turntable 361 to rotate.

[0023] A quarter sawtooth is arranged on the No. 1 bevel gear 323, the No. 2 bevel gear 34 is a complete gear, a plurality of No. 1 bevel gears 323 are arranged around the No. 2 bevel gear 34, and the rotating rod 321 is connected to the No. 1 bevel gear 323 by penetrating the protective shell 1, and the stabilizing device 4 includes a threaded screw 41, one end of the threaded screw 41 is rotatably connected to the turntable 361, and the other end of the threaded screw 41 is telescopically connected to one end of a telescopic rod 411, and the outer wall of the other end of the telescopic rod 411 is fixedly connected to one end of a plurality of No. 1 extension rods 412, and the other end of the No. 1 extension rod 412 is rotatably connected to the bending rod 44.

[0024] The stabilizing device 4 includes a sliding member 42, which is slidably connected to the outer wall of the threaded screw 41. The upper outer wall of the sliding member 42 is fixedly connected to one end of a plurality of No. 2 extension rods 421. The other end of the No. 2 extension rod 421 is rotatably connected to one end of a connecting rod 43. The other end of the connecting rod 43 is rotatably connected to one end of a bending rod 44.

[0025] It can be seen that during the operation of the tower crane, when the wind speed in the air is too fast, the strong wind blows the wind direction assembly 3, and the wind direction rod 322 is tilted. During the tilting process of the wind direction rod 322, the rotating rod 321 will be driven to rotate a certain angle, and at the same time, the rotating rod 321 will drive the No. 1 bevel gear 323 to rotate. The outer rack of the No. 1 bevel gear 323 will rotate a certain angle together with the wind direction rod 322. When the No. 1 bevel gear 323 rotates to the edge of the rack, it will no longer drive the No. 2 bevel gear 34 to rotate. At the same time, the threshold value of the wind speed that can be tolerated can be determined by setting the distance between the No. 1 fixed columns 33 on both sides in advance. When the outer wall of the wind direction rod 322 will abut against the touch sensor 331, when the touch sensor 331 is squeezed, it is the threshold value for tolerating the wind speed, and an alarm will be issued to the operator to provide an early warning effect.

[0026] During the installation of the tower crane, as the installation height of the tower crane continues to increase, the wind speed will become faster and faster, and the force on the wind direction rod 322 will continue to increase. Therefore, as the height continues to increase, the staff also needs to continuously adjust the position between the No. 1 fixed column 33 through the control end to ensure the safety of the operator and surrounding objects. Embodiment 2

[0027] Different from the first embodiment, in order to achieve the stability of the operator when steering, Figure 5-7 As shown, the bending 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 No. 1 extension rod 412 is rotatably connected to the connection between 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, the long rod 441 is fixedly connected with a snap member 4411 at the end away from the No. 1 extension rod 412, a blocking plate 4412 is fixedly connected to the top middle end of the long rod 441, a stabilizing member 45 is fixedly connected between the blocking plate 4412 and the snap member 4411, and 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, and an annular groove is opened on the outer wall of the rotating shaft 5, and the shape of the annular groove is consistent with the state of multiple rubber pads 451 closed into a ring.

[0028] It can be seen that the No. 1 bevel gear 323 drives the No. 2 bevel gear 34 to rotate, and at the same time drives the turntable 361 and the threaded screw 41 to rotate. During the rotation of the threaded screw 41, the sliding member 42 will be driven to slide upward, and at the same time, the No. 2 extension rod 421 will be driven to move upward. At this time, the No. 2 extension rod 421 pushes the connecting rod 43 and pushes the bending rod 44 to rotate upward. At this time, the bending 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 shrink and close together to clamp the rotating shaft 5. During the rotation of the rotating shaft 5, a greater friction force can be applied, and the shape of the inner side of the annular groove of the rotating shaft 5 is matched with the inner side of the rubber pad 451 that is closed together. At this time, the rotating shaft 5 will be continuously blocked and affected by the friction force of the rubber pad 451 during the rotation, making it more stable during the rotation process.
