Description

Technical Field

[0001] This utility model relates to the field of outrigger adjustment technology, and in particular to an intelligent hydraulic balance adjustment outrigger for hoisting large wind turbine units. Background Technology

[0002] Adjustable outriggers are used to level the hoisting machine for lifting large wind turbines. The adjustable outriggers consist of a mounting platform, telescopic frame, cylinder assembly, base plate, level sensor, displacement sensor, and pressure sensor. When using the adjustable outriggers, they are transported to the installation area of ​​the large wind turbine via a transport vehicle. Then, the first cylinder in the telescopic frame is activated, causing the frame to extend. The base plate is then placed directly under the second cylinder, and the second cylinder is activated again, extending to contact the base plate and then securing it. The height of the mounting platform is adjusted by the extension / retraction of the second cylinder. Simultaneously, the level sensors on both sides of the mounting platform, through a controller, calculate the tilt angle and intelligently adjust the level of the mounting platform by controlling the extension / retraction of the second cylinder. The crane is then installed on the mounting platform, ensuring stable lifting of the wind turbine. This allows for real-time adaptation to the complex and diverse geological conditions of the Gobi Desert region, minimizing crane tilting and imbalance that could affect lifting safety and accuracy. Meanwhile, the displacement and pressure sensors within the second cylinder detect the extension / retraction of the second cylinder, ensuring synchronized operation of multiple cylinders. The pressure sensor also monitors the pressure of the second cylinder to prevent overload.

[0003] In their daily work, the inventors discovered that when adjusting the outriggers, due to the complex and diverse geological conditions in the desert area, some ground is soft sand with poor bearing capacity. In order to improve the stability of the base plate, four ground nails are usually driven into the ground above the base plate. However, the workers usually drive the four ground nails into the ground by holding a hammer. Since there are many ground nails, it may make the labor intensity of the workers high. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that in actual use, due to the complex and diverse geological conditions in the desert area, some of the ground is soft sand with poor bearing capacity. In order to improve the stability of the base plate, four ground nails are usually driven into the ground above the base plate. However, it is common for workers to drive four ground nails into the ground by hand with a hammer. The large number of ground nails driven in may result in high labor intensity for workers. Therefore, this utility model proposes an intelligent hydraulic balance adjustment outrigger for hoisting large wind turbine units.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an intelligent hydraulic balance adjustment outrigger for hoisting large wind turbine units, comprising a mounting platform, a telescopic frame mounted on the arc surface of the mounting platform, a second cylinder mounted on the other end of the telescopic frame, a base plate disposed below the output end of the second cylinder, an auxiliary stabilizing component and a fixing component disposed on the upper end of the base plate, level sensors mounted on both sides of the upper end of the mounting platform, a displacement sensor and a pressure sensor disposed inside the second cylinder, the auxiliary stabilizing component comprising four identical ground spikes penetrating the upper end of the base plate, a fixing frame fixedly connected to the upper end of the ground spikes, a sprocket disposed on the upper end of the base plate, the sprockets being threadedly connected to the ground spikes, a chain disposed between the plurality of sprockets, and a toothed ring fixedly connected above the sprockets.

[0006] The effect achieved by the above components is as follows: by setting auxiliary stabilizing components, when it is necessary to drive the ground nails into the ground, the drive mechanism causes the toothed ring to rotate, which in turn drives the sprocket to rotate. Through chain transmission, the four sprockets rotate, and with the cooperation of the fixed frame, the four ground nails move downward and insert into the ground, improving the stability of the base plate, thereby reducing the labor intensity of workers as much as possible.

[0007] Preferably, the upper end of the base plate is provided with a rotating rod rotatably connected by a first bearing. The upper end of the rotating rod is provided with an internal hexagonal groove. A gear is fixedly connected to the arc surface of the rotating rod, and the gear ring meshes with the gear.

[0008] The effect achieved by the above components is as follows: the worker holds a hand drill, so that the output end is inserted into the internal hexagonal slot, and then starts the hand drill, so that the rotating rod rotates, so that the gear rotates, so that the gear ring rotates.

[0009] Preferably, a ring is fixedly connected to the upper end of the mounting platform, a second bearing is provided on the arc surface of the ring, a connecting ring is fixedly connected to the lower end of the sprocket, and the outer ring of the second bearing is fixed to the connecting ring.

[0010] The effect achieved by the above components is to assist the rotation of the sprocket by setting up a ring, a second bearing, and a connecting ring.

[0011] Preferably, auxiliary limiting plates are rotatably connected to both sides of the arc surface of the ground nail, and the inner ring of the second bearing is fixed to the ring.

[0012] The effect achieved by the above components is as follows: after the ground nail is inserted into the ground, the auxiliary limiting plate is inserted into the ground as well. When the base plate is subjected to an upward force, the auxiliary limiting plate comes into contact with the soil and is opened, thereby assisting in limiting the base plate. When disassembling the base plate, it can be removed by digging.

[0013] Preferably, the fixing component includes a rectangular block fixedly connected to the upper end of the base plate, and a square pin is slidably inserted into the inner wall of the rectangular block, the square pin being inserted into the second cylinder.

[0014] The effect achieved by the above components is as follows: when it is necessary to fix the base plate to the second cylinder, the second cylinder is activated, so that the output end is inserted into the rectangular block, and then the square pin is locked into the second cylinder by the pushing mechanism for fixation.

[0015] Preferably, the left end of the square pin is rotatably connected to a lead screw, which is threadedly connected to the rectangular block.

[0016] The effect achieved by the above components is that by turning the screw with a screwing tool, the square pin is pushed.

[0017] Preferably, the rectangular block has multiple evenly distributed positioning slots on both sides, the lead screw has a plug inserted into its front side, and the plug has a protrusion on its arc surface.

[0018] The effect achieved by the above components is to insert the plug rod into the positioning groove and fix the lead screw.

[0019] Preferably, a spring is fixedly connected to one side of the insertion rod, and the other end of the spring is fixed to the lead screw.

[0020] The effect achieved by the above components is that by setting a spring, the insertion rod is pulled, thereby providing auxiliary limiting for the insertion rod.

[0021] In summary, the beneficial effects of this utility model are as follows:

[0022] In this invention, by setting up an auxiliary stabilizing component, when it is necessary to drive the ground nails into the ground, the drive mechanism causes the toothed ring to rotate, which in turn drives the sprockets to rotate. Through chain transmission, the four sprockets rotate, and with the cooperation of the fixed frame, the four ground nails move downwards and insert into the ground, improving the stability of the base plate. This reduces the labor intensity of workers as much as possible. It solves the problem that in sandy wasteland areas with complex and diverse geological conditions, some of which are soft sandy ground with poor bearing capacity, four ground nails are usually driven into the ground above the base plate to improve its stability. However, driving four ground nails into the ground is usually done by workers holding hammers, and the large number of ground nails driven in can lead to high labor intensity for workers.

[0031] The following section will explain the specific settings and functions of the auxiliary stabilizing component 2 and the fixing component 3.

[0032] Reference Figure 2 and Figure 3As shown in this embodiment: the auxiliary stabilizing component 2 includes four identical ground nails 21 penetrating the upper end of the base plate 7. A fixing frame 22 is fixedly connected to the upper end of each ground nail 21. A sprocket 23 is provided at the upper end of the base plate 7, and the sprocket 23 is threadedly connected to the ground nail 21. A chain 24 is provided between the multiple sprockets 23. A toothed ring 28 is fixedly connected above the sprockets 23. By setting the auxiliary stabilizing component 2, when the ground nails 21 need to be driven into the ground, the drive mechanism causes the toothed ring 28 to rotate, which in turn drives the sprockets 23 to rotate. This is transmitted through the chain 24, causing the four sprockets 23 to rotate. With the cooperation of the fixing frame 22, the four ground nails 21 descend and insert into the ground, improving the stability of the base plate 7, thereby minimizing the labor intensity of workers. A rotating rod 25 is provided at the upper end of the base plate 7, rotatably connected by a first bearing. An internal hexagonal groove 27 is provided at the upper end of the rotating rod 25, and a gear 26 is fixedly connected to the arc surface of the rotating rod 25. The gear ring 28 meshes with the gear 26. The worker holds a hand drill, causing the output end to engage with the internal hexagonal socket 27. Then, the hand drill is activated, causing the rotating rod 25 to rotate, which in turn rotates the gear 26 and the gear ring 28. A circular ring 29 is fixedly connected to the upper end of the mounting platform 1. A second bearing 210 is mounted on the arc surface of the circular ring 29. A connecting ring 211 is fixedly connected to the lower end of the sprocket 23. The outer ring of the second bearing 210 is fixed to the connecting ring 211. This is achieved by setting the circular ring 29... The second bearing 210 and connecting ring 211 rotate, the auxiliary sprocket 23 rotates, and the two sides of the arc surface of the ground nail 21 are rotatably connected to the auxiliary limiting plate 212. The inner ring of the second bearing 210 is fixed to the ring 29. After the ground nail 21 is inserted into the ground, the auxiliary limiting plate 212 is inserted into the ground. When the base plate 7 is subjected to an upward force, the auxiliary limiting plate 212 contacts the soil and is opened, thereby assisting in limiting the base plate 7. When disassembling the base plate 7, it can be removed by digging.

[0033] Reference Figure 4 and Figure 5As shown, in this embodiment: the fixing component 3 includes a rectangular block 31 fixedly connected to the upper end of the base plate 7. A square pin 32 is slidably inserted into the inner wall of the rectangular block 31. The square pin 32 is inserted into the second cylinder 6. When it is necessary to fix the base plate 7 to the second cylinder 6, the second cylinder 6 is activated, so that the output end is inserted into the rectangular block 31. Then, through the pushing mechanism, the square pin 32 is locked into the second cylinder 6 for fixation. The left end of the square pin 32 is rotatably connected to a lead screw 33, and the lead screw 33 is screwed into the rectangular block 31. The screw rod 33 is screwed in by a screwing tool, which pushes the square pin 32. The rectangular block 31 has multiple evenly distributed positioning slots 35 on both sides. The screw rod 33 has a rod 34 inserted into its front side. The rod 34 has a protrusion on its arc surface. The rod 34 is inserted into the positioning slot 35 to fix the screw rod 33. A spring 36 is fixedly connected to one side of the rod 34. The other end of the spring 36 is fixed to the screw rod 33. By setting the spring 36, the rod 34 is pulled, which helps to limit the movement of the rod 34.

[0034] Working principle:

[0035] When using the adjustable outriggers, they are transported to the installation area for the large wind turbine via a transport vehicle. Then, the first cylinder inside the telescopic frame 5 is activated, extending the frame. Next, the base plate 7 is placed directly below the second cylinder 6, which is then activated to extend and contact the base plate 7, and then fixed in place. The height of the mounting platform 1 is adjusted by the extension / retraction of the second cylinder 6. Simultaneously, the horizontal sensors 4 (model: Prisen SN-3001-DIP tilt sensors) on both sides of the mounting platform 1 calculate the tilt angle via a controller, and then intelligently adjust the level of the mounting platform 1 by controlling the extension / retraction of the second cylinder 6. Finally, the crane is installed on the mounting platform 1. To ensure the crane can smoothly lift the fan, it adapts in real time to the complex and diverse geological conditions of the desert and Gobi regions, minimizing crane tilting and imbalance that could affect lifting safety and accuracy. Simultaneously, displacement and pressure sensors within the second cylinder 6 (these are commercially available products; their specific usage is not detailed here) detect the extension and retraction of the second cylinder 6, ensuring synchronized operation of multiple cylinders. The pressure sensor also monitors the pressure within the second cylinder 6 to prevent overload. When it's time to drive the ground stake 21 into the ground, workers use a hand drill to... The output end is inserted into the internal hexagonal slot 27. Then, the hand drill is started, causing the rotating rod 25 to rotate, which in turn causes the gear 26 to rotate, which in turn causes the gear ring 28 to rotate. The gear ring 28 rotates, which in turn drives the sprocket 23 to rotate. Through the chain 24, the four sprockets 23 rotate. With the cooperation of the fixed frame 22, the four ground nails 21 move downward and insert into the ground, improving the stability of the base plate 7, thereby minimizing the labor intensity of workers. By setting the ring 29, the second bearing 210, and the connecting ring 211, the sprockets 23 are assisted in rotating. After the ground nails 21 are inserted into the ground, the auxiliary limiting plate 212 follows and inserts into the ground. Within the soil, when the base plate 7 is subjected to an upward force, the auxiliary limiting plate 212 contacts the soil, causing it to open and thus assisting in limiting the base plate 7. When disassembling the base plate 7, it can be removed by digging. When it is necessary to fix the base plate 7 to the second cylinder 6, the second cylinder 6 is activated, causing the output end to be inserted into the rectangular block 31. Then, by using a screw-operated tool to turn the lead screw 33, it pushes the square pin 32, causing the square pin 32 to be locked into the second cylinder 6 for fixation. The insertion rod 34 is inserted into the positioning groove 35 to fix the lead screw 33. By setting a spring 36, the insertion rod 34 is pulled, thus assisting in limiting the insertion rod 34.
