Description

Technical Field

[0001] The utility model relates to the technical field of aircraft, in particular to a mooring tower. Background Art

[0002] An airship mooring tower, also known as a mooring balloon tower or an airship docking tower, is an infrastructure specifically designed for lighter-than-air aircraft such as airships and balloons. It is mainly used for the docking, maintenance, takeoff and landing, and stability control of airships. Existing mooring towers fix airships to the tower through mooring ropes to prevent them from drifting with the wind and ensure the safety of the aircraft when on the ground.

[0003] However, due to the high height of the airship mooring tower and the inability to adjust the height, the mooring tower is easily restricted by the driving height during transportation. At the same time, the height of the mooring tower cannot be changed, which easily causes the mooring tower to shake during transportation and results in damage to the mooring tower. For this reason, we propose a mooring tower to solve the above problems. Content of the Utility Model

[0004] The purpose of the utility model is to provide a mooring tower to solve the problem that the height of the mooring tower cannot be adjusted.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme: A mooring tower includes a fixed platform. A fixed tower is provided at the upper end of the fixed platform. A movable tower is hinged to the upper end of the fixed tower. An installation platform is provided at the upper end of the movable tower. A winch is provided at the upper end of the fixed platform. The winch is used to tighten the head mooring rope at the front end of the airship. A driving member is provided on the outer wall of the fixed tower. The output end of the driving member is connected to the movable tower.

[0006] The beneficial effect of this scheme is: By hinging the movable tower to the upper end of the fixed tower, when the mooring tower needs to be transported, the angle of the movable tower is adjusted through the driving member, thereby reducing the driving height of the mooring tower and increasing the portability of the mooring tower. When the airship needs to be moored, the movable tower is rotated through the driving member to be docked with the fixed tower. The head mooring rope of the airship passes through the installation platform and is connected to the winch. At this time, the head mooring rope is tightened through the winch to fix the airship, so as to quickly complete the mooring of the airship. This scheme can quickly complete the conversion between the two modes and improve the mooring work efficiency.

[0007] Preferably, as an improvement, the driving member includes a screw jack and a motor. The screw jack is provided on the outer wall of the fixed tower. A sleeve is sleeved on the output end of the screw jack. The sleeve is hinged to the lower end of the movable tower. The motor is provided on the outer wall of the screw jack. The output end of the motor is connected to the input end of the screw jack.

[0008] The beneficial effects are as follows: The motor provides power for the screw lift, causing the worm of the screw lift to rotate. The worm drives the worm wheel to rotate, and finally the rotation of the worm wheel causes the screw threadedly connected thereto to expand and contract. The rotation of the screw is offset by the sleeve, and then the rotation of the movable tower is controlled by the expansion and contraction of the screw. When the mooring tower needs to be transported, the screw is extended to tilt the movable tower, thereby reducing the height of the low mooring tower. When the mooring tower needs to work, the motor is started to contract the screw, causing the screw to pull the movable tower to a vertical state and dock with the fixed tower, thus quickly completing the assembly.

[0009] Preferably, as an improvement, fixing frames are symmetrically arranged at the upper end of the fixed tower. Fixing components are symmetrically arranged on the outer wall of the fixing frames. The fixing components include mounting boxes, pins and springs. The mounting boxes are arranged on the outer wall of the fixing frames. The pins penetrate through the inside of the mounting boxes, and one end of the pins extends into the fixing frames. A limiting ring is arranged on the outer wall of the pins, and the limiting ring is located inside the mounting boxes. The springs are sleeved on the outer walls of the pins, and one end is connected to the limiting ring and the other end is connected to the inner wall of the mounting boxes. Locking grooves and release grooves are formed at one end of the mounting boxes away from the fixing frames, and the locking grooves are perpendicular to the release grooves. Limiting rods are arranged on the outer walls of the pins, and the limiting rods can be engaged with the locking grooves and the release grooves. Locking blocks are symmetrically arranged at the lower end of the movable tower, and the locking blocks can be inserted into the fixing frames. Limiting grooves are symmetrically formed on the outer walls of the locking blocks, and the pins can be inserted into the limiting grooves.

[0010] The beneficial effects are as follows: The locking blocks arranged at the lower end of the movable tower are engaged with the fixing components, so that the movable tower is fixed to the fixed tower, further improving the stability of the mooring tower during work. The pins are engaged through the locking grooves and the release grooves. When the pins are located in the locking grooves, the pins are engaged with the limiting grooves on the outer walls of the locking blocks, thereby fixing the locking blocks. When the pins are located in the release grooves, the springs are in a stretched state. At this time, the pins are located inside the mounting boxes and unlock the locking blocks.

[0011] Preferably, as an improvement, tower ladders are arranged on the outer walls of both the fixed tower and the movable tower

[0012] The beneficial effects are as follows: The tower ladders are provided to facilitate the staff to climb.

[0013] Preferably, as an improvement, a workbench is arranged on the outer wall of the movable tower.

[0014] The beneficial effects are as follows: The staff stands on the workbench to perform mooring operations on the installation platform, increasing the safety of the staff during operation.

[0015] Preferably, as an improvement, pull rings are arranged at one ends of all the pins away from the fixing frames.

[0016] The beneficial effects are as follows: The pull rings facilitate the staff to pull out the pins, thus quickly completing the transformation of the mooring tower mode. Description of the Drawings

A fixing tower 2 is fixedly installed at the upper end of the fixing platform 1. A movable tower 3 is hinged to the rear side of the upper end of the fixing tower 2. Tower ladders 18 are fixedly installed on the outer walls of both the fixing tower 2 and the movable tower 3. When the fixing tower 2 is docked with the movable tower 3, the tower ladders 18 are also docked with each other. An installation platform 4 is provided at the upper end of the movable tower 3. A workbench 19 is fixedly installed on the outer wall of the movable tower 3. The workbench 19 is located at the upper end of the tower ladder 18 on the outer wall of the movable tower 3. A winch 5 is fixedly installed at the upper end of the fixing platform 1. The winch 5 is used to tighten the head cable at the front end of the airship. A driving member is provided on the outer wall of the fixing tower 2. The output end of the driving member is connected to the movable tower 3.

[0024] The driving member includes a screw lift 6 and a motor 7. As Figure 2 shown, the housing of the screw lift 6 is rotatably installed on the outer wall of the fixing tower 2. The screw lift 6 includes a worm gear, a worm, and a screw rod. The worm gear is threadedly connected to the outer wall of the screw rod. The worm gear is meshed with the worm. A sleeve is rotatably sleeved at one end of the screw rod of the screw lift 6 close to the movable tower 3. The sleeve is hinged to the lower end of the movable tower 3. The sleeve can offset the self-rotation of the screw rod, thereby transmitting the telescoping of the screw rod to the movable tower 3. The motor 7 is fixedly installed on the housing of the screw lift 6. The output end of the motor 7 is fixedly connected to the worm of the screw lift 6.

[0025] Fixing frames 8 are symmetrically provided at the upper end of the fixing tower 2. As Figure 2As shown, fixing components are symmetrically arranged on the outer wall of the fixing frame 8. The fixing components include an installation box 9, a bolt 10, and a spring 11. As Figure 3 shown, the installation box 9 is fixedly installed on the outer wall of the fixing frame 8. The bolt 10 slides through the interior of the installation box 9, and one end of the bolt 10 extends through and into the fixing frame 8. A limiting ring 12 is fixedly installed on the outer wall of the bolt 10, and the limiting ring 12 is located inside the installation box 9. The spring 11 is sleeved on the outer wall of the bolt 10, with one end connected to the limiting ring 12 and the other end connected to the inner wall of the installation box 9. A locking groove 13 and a release groove 14 are formed at one end of the installation box 9 away from the fixing frame 8, and the locking groove 13 is perpendicular to the release groove 14. The depth of the locking groove 13 is greater than that of the release groove 14. A limiting rod 15 is fixedly installed on the outer wall of the bolt 10, and the limiting rod 15 can be engaged with the locking groove 13 and the release groove 14. Symmetrically fixed at the lower end of the movable tower 3 are locking blocks 16, and the locking blocks 16 can be inserted into the fixing frame 8. Symmetrically formed on the outer wall of the locking blocks 16 are limiting grooves 17, and the bolts 10 can be inserted into the limiting grooves 17. At one end of each bolt 10 away from the fixing frame 8 is provided a pulling ring 20.

[0026] The specific implementation process is as follows:

[0027] When the mooring tower needs to perform mooring operations, the staff first pull the limiting rod 15 into the release groove 14 through the pulling ring 20, so that each bolt 10 is located inside the installation box 9. At this time, the motor 7 is started, causing the screw rod of the screw elevator 6 to contract, driving the movable tower 3 to dock with the fixed tower 2. When the locking block 16 is inserted into the fixing frame 8, the staff rotate the bolt 10 by 90° through the pulling ring 20. The bolt 10 is inserted into the fixing frame 8 under the action of the spring 11, and the limiting rod 15 also moves into the locking groove 13. At this time, the bolt 10 is inserted into the limiting groove 17 on the outer wall of the locking block 16, completing the fixation of the movable tower 3. Then, the staff climb onto the workbench 19 through the tower ladder 18, and pass the head cable of the airship through the installation platform 4 and connect it to the winch 5. At this time, the head cable is tightened by the winch 5 to fix the airship, thus quickly completing the mooring of the airship;

[0028] When it is necessary to lower the height of the mooring tower, the staff only need to pull the bolt 10 and the limiting rod 15 out of the locking groove 13 through the pulling ring 20, and rotate the bolt 10 by 90° to engage the limiting rod 15 in the release groove 14, thus unlocking the locking block 16 in the fixing frame 8. At this time, the staff start the motor 7, causing the screw rod of the screw elevator 6 to extend, and pushing the movable tower 3 to tilt away from the motor 7, thereby reducing the height of the mooring tower and increasing the portability of transporting the mooring tower.
