Description

Technical Field

[0001] This invention belongs to the field of tethered operation vehicles for tethered balloons, airships, high-altitude balloons and other aerostats, and specifically relates to a working platform for a tethered balloon operation vehicle. Background Technology

[0002] The airship anchoring vehicle is mainly used for the launch and recovery of tethered balloons, and for anchoring the balloons with cables when they are in a fixed position. In addition, it is used for the ground anchoring of tethered balloons, serves as a work platform for ground maintenance and inspection of tethered balloons, and can also perform ground towing and road transport.

[0003] During the balloon's ascent, personnel are needed to perform auxiliary work on the roof of the anchoring vehicle. As the balloon ascends further, sometimes personnel cannot reach the working equipment and observation holes at the bottom of the balloon, so ladders are required for climbing.

[0004] Ladders are inconvenient to use, and they need to be securely fixed to a platform to ensure the safety of workers. Since balloon launches and retrievals typically take place at night, involving frequent work at heights, ladders are impractical due to the need to ensure worker safety. Summary of the Invention

[0005] This invention provides a tethered balloon operation vehicle platform that can meet the needs of tethered balloon launch and retrieval operations without the need for a ladder.

[0006] This invention provides a tethered balloon operation vehicle working platform, comprising: an anchoring operation vehicle 1, a rear truss 2, a telescopic truss 3, and a working platform 4; wherein,

[0007] The rear truss 2 is mounted on the anchoring vehicle 1; a telescopic truss 3 is slidably fitted inside the rear truss 2;

[0008] The working platform 4 is mounted on the telescopic truss 3. When the telescopic truss 3 is pushed out from the rear truss 2, the working platform 4 is exposed.

[0009] The work platform 4 adopts a lifting mode and includes: folding railings 41 and platform body 42;

[0010] Folding railings 41 are arranged around the platform body 42. When the platform body 42 is raised, the folding railings 41 are opened.

[0011] Optional components include structural part 21, first hydraulic cylinder 22, and slide rail 23;

[0017] Optionally, the work platform 4 may also include: pin 43, folding rod 44, pin 45, two second hydraulic cylinders 46, and fixing pin 48;

[0018] Two second hydraulic cylinders 46 are installed at the top of the telescopic truss 3;

[0019] The folding rod 44 includes four rods, and every two folding rods 44 are hinged in the middle by a pin 45 to form a folding rod assembly;

[0020] The upper ends of each folding rod 44 are hinged to the platform body 42 by pins 43. The lower end of one folding rod in the same folding rod assembly is hinged to the top of the telescopic truss 3 by a fixing pin 48, and the lower end of the other folding rod is hinged to a second hydraulic cylinder 46.

[0021] By simultaneously extending and retracting two second hydraulic cylinders 46, the two connected folding rods 44 are moved, thereby controlling the lifting and lowering of the platform body 42.

[0022] Optionally, the work platform 4 may also include: a sliding plate 47;

[0023] The sliding plate 47 is fixed to the top of the telescopic truss 3;

[0024] The second hydraulic cylinder 46 is mounted on the sliding plate 47. The moving end of the second hydraulic cylinder 46 is connected to the folding rod 44 and slides on the sliding plate 47.

[0025] Optionally, the bottom of the folding railing 41 adopts a single or double ear design and is connected to the platform body 42, which can realize the folding and unfolding of the folding railing 41.

[0026] Optionally, the mooring vehicle 1 is modified from a professional chassis and equipped with mechanical, electrical, hydraulic and system control equipment.

[0041] The tethered balloon operation vehicle platform provided by the present invention will be further described below with reference to the accompanying drawings.

[0042] like Figure 1-8 As shown, the present invention provides a working platform for a tethered balloon operation vehicle.

[0043] The anchoring vehicle mainly consists of a tractor (with a crane), a semi-trailer, a slewing device, a slewing platform, an equipment compartment, a control room, auxiliary equipment (including air conditioning, lighting, and a heater), as well as a power supply box, a power control box, an on-board integrated power supply, and a diesel generator.

[0044] The head and middle mechanical rigging are secured by the head cone, the guide wheel at the end of the tethered arm, and the auxiliary vehicle of the ascent and recovery subsystem. The rotational torque generated by the tethered balloon under the action of wind allows the tethered balloon to rotate 360° around the support in the horizontal plane, ensuring that the axis of the tethered balloon is consistent with the wind direction and improving the safety of the system.

[0045] This work platform is mounted on the mooring work vehicle and used in conjunction with the vehicle. It mainly includes the mooring work vehicle 1, the rear truss 2, the telescopic truss 3, and the work platform 4.

[0046] The specific structure is as follows:

[0047] 1. Mooring work vehicle

[0048] The mooring operation vehicle 1 is mainly modified from a professional chassis, on which mechanical, electrical, hydraulic, and system control equipment are installed.

[0049] 2. Rear Truss

[0050] The rear truss 2 mainly includes a structural part 21, two sets of first hydraulic cylinders 22, and a slide rail 23. The first hydraulic cylinders 22 are mainly responsible for pushing out or retracting the telescopic truss. The slide rail 23 is mainly composed of channel steel and is welded and fixed to the structural part 21 of the rear truss to ensure that the telescopic truss 3 slides in the longitudinal direction of the vehicle.

[0051] 3. Telescopic truss

[0052] The telescopic truss 3 is nested inside the rear truss 2 and slides back and forth within the slide rail 23 of the rear truss 2.

[0053] 4. Work Platform

[0054] The work platform 4 adopts a lifting mode and mainly includes a folding railing 41, a platform body 42, a pin 43, a folding rod 44, a pin 45, a second hydraulic cylinder 46, a sliding plate 47, and a fixing pin 48.

[0055] The bottom of the railing 41 adopts a single and double lug design and is connected to the platform body 42, allowing the railing to be folded and extended. The upper end of the folding rod 44 is hinged to the platform via a pin 43. The lower end of one folding rod is hinged to the telescopic truss via a fixing pin 48, and the lower end of the other folding rod is hinged to the second hydraulic cylinder 46. The platform body 42 rises and falls as the second hydraulic cylinder extends and slides on the sliding plate 47.

[0056] Example 1

[0057] The tethered balloon operation vehicle working platform provided by this invention enables the lifting and lowering test of the working platform.

[0058] Implement this process in the following steps:

[0059] (1) First, the telescopic truss is deployed using the first hydraulic cylinder of the rear truss.

[0060] (2) The second cylinder of the working platform extends to raise the working platform.

[0061] (3) Open and lock the folding railing on the work platform.

[0062] (4) The withdrawal and opening processes are reversed.
