Description

Technical Field

[0001] This utility model relates to the field of wind turbine tower installation technology, and in particular to a detachable and convenient tower torque wrench operating tool. Background Technology

[0002] Currently, the installed capacity of wind power units in the new energy market is getting larger and taller. To prevent tower resonance collapse, the nacelle must be hoisted after the top section of the tower is installed. Tightening the torque after tower installation typically takes 3 hours, with the majority of the time spent manually handling the torque wrench. This prolonged tightening time increases the risk of tower resonance collapse during wind turbine installation. Therefore, reducing the tightening time can reduce the installation risk. For this reason, it is necessary to research a detachable and convenient tower torque wrench operating tool. Summary of the Invention

[0003] This utility model aims to solve the problem in the prior art that the long back-and-forth transportation time of torque wrenches and hydraulic pump stations leads to excessively long wind turbine tower installation time, thereby increasing the risk of tower resonance and collapse. It provides a detachable and convenient tower torque wrench operating tool.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a detachable and convenient tower torque wrench operating tool, including an anti-slip rubber pad, a lower base support, a support rod, a rotating bracket, a lever arm balance bar, a torque wrench adjusting rod, and a hydraulic pump station hanging support rod; the anti-slip rubber pad is installed at the bottom of the lower base support, the support rod is installed at the top center of the lower base support, the rotating bracket is rotatably installed at the top of the support rod, the lever arm balance bar is rotatably installed inside the rotating bracket via a pin, the torque wrench adjusting rod is telescopically sleeved inside one side of the lever arm balance bar, a torque wrench mounting sleeve is provided on the side of the torque wrench adjusting rod away from the lever arm balance bar, the hydraulic pump station hanging support rod is inserted through and installed on the side of the lever arm balance bar away from the torque wrench adjusting rod, the hydraulic pump station is suspended on the hydraulic pump station hanging support rod, and the torque wrench is clamped on the torque wrench mounting sleeve.

[0005] Specifically, the lower chassis support is circular, and the anti-slip rubber pad is fixed to the lower chassis support with bolts.

[0006] Specifically, a first sleeve is provided at the top center of the lower chassis support, and the first sleeve and the bottom of the support rod are respectively provided with pin holes. The support rod is inserted into the first sleeve and fixed by installing a pin in the pin hole.

[0007] Specifically, the support rod is hollow inside and has rounded corners at the top edge.

[0008] Specifically, the rotating support includes a second sleeve with a rotating seat at the top. The second sleeve is rotatably fitted onto the top of the support rod, and the lever arm balance bar is rotatably connected to the rotating seat via a pin.

[0009] The beneficial effects of this utility model are: it is convenient to install, dismantle, relocate, and transport on-site, and is suitable for the installation of all types of wind turbine towers, including steel towers and mixed towers. The torque tightening is achieved by rotating the tower center using a torque wrench and a hydraulic pump station. Compared to the conventional torque tightening team of 4-6 people, only 2 people are needed to complete all torque tightening, which greatly shortens the tightening time, effectively reduces the installation time and personnel input for wind turbine tower torque tightening, improves tower installation efficiency, and reduces the risk of tower resonance collapse.

[0014] The following will describe in detail the embodiments of this utility model with reference to the accompanying drawings. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0016] like Figures 1-3 As shown, a detachable and convenient tower torque wrench operating tool includes an anti-slip rubber pad 1, a lower base support 2, a support rod 3, a rotating bracket 4, a lever arm balance bar 5, a torque wrench adjusting rod 6, and a hydraulic pump station hanging support rod 7. The anti-slip rubber pad 1 is installed at the bottom of the lower base support 2, which is circular. The anti-slip rubber pad 1 is fixed to the lower base support 2 with bolts to prevent the lower base support 2 from rotating with the lever arm balance bar 5 in the tower.

[0017] The support rod 3 is installed at the top center of the lower chassis support 2. The top center of the lower chassis support 2 is provided with a first sleeve 9. The bottom of the first sleeve 9 and the support rod 3 are respectively provided with pin holes. The support rod 3 is inserted into the first sleeve 9 and fixed by installing a pin in the pin hole.

[0018] The rotating bracket 4 is rotatably mounted on the top of the support rod 3. The lever arm balance bar 5 is rotatably mounted inside the rotating bracket 4 via a pin. The rotating bracket 4 includes a second sleeve 10. The top of the second sleeve 10 is provided with a rotating seat 11. The second sleeve 10 is rotatably fitted onto the top of the support rod 3. The lever arm balance bar 5 is rotatably connected to the rotating seat 11 via a pin. The support rod 3 is hollow inside and has rounded corners at the top edge to reduce friction during the rotation of the rotating bracket 4.

[0019] The torque wrench adjusting rod 6 is telescopically sleeved inside the lever arm balance bar 5 on one side. A torque wrench mounting sleeve 8 is located on the side of the torque wrench adjusting rod 6 away from the lever arm balance bar 5. The hydraulic pump station suspension support rod 7 is inserted through and positioned on the side of the lever arm balance bar 5 away from the torque wrench adjusting rod 6. The hydraulic pump station is suspended on the hydraulic pump station suspension support rod 7, and the torque wrench is secured in the torque wrench mounting sleeve 8. One person can operate the torque wrench adjusting rod 6 to lift the hydraulic pump station off the tower platform, allowing for torque tightening by rotating the torque wrench, thus improving installation efficiency.

[0020] During operation, this device is placed on the tower platform and fixed before the tower is hoisted. After the tower is hoisted, the construction team can disassemble the device and connect it to the hydraulic pump station and torque wrench. During use, only one person needs to operate the torque wrench adjustment rod 6 to move the hydraulic pump station away from the tower platform. Then, the torque wrench can be rotated to tighten the torque. Then, the torque wrench and hydraulic pump station are rotated along the center of the tower, reducing the need for personnel to carry back and forth. All torque tightening requirements can be completed by a single person. Finally, after the torque tightening is completed and accepted, the device is disassembled and transported to the ground using the wind turbine elevator for installation on the next wind turbine.

[0021] This utility model is convenient for on-site installation, dismantling, relocation, and transportation. It is suitable for the installation of all types of wind turbine towers, including steel towers and mixed towers. The torque is tightened by rotating the tower center using a torque wrench and a hydraulic pump station. Compared to the conventional torque tightening team of 4-6 people, only 2 people are needed to complete all torque tightening, which greatly shortens the tightening time, effectively reduces the installation time and personnel input of wind turbine tower torque, and improves the tower installation efficiency, while reducing the risk of tower resonance collapse.
