Description
Technical Field
[0001] This utility model relates to the field of vehicle auxiliary equipment technology, specifically a device for getting out of trouble for heavy transport vehicles. Background Technology
[0002] Most wind farms are located in mountainous and hilly areas, making it difficult to construct roads for transporting heavy items. Some sections of these roads are narrow, and the uneven surfaces caused by long-term compaction make it easy for heavy transport vehicles to get stuck.
[0003] The common solution for heavy-duty transport vehicles getting stuck is to tow them with a loader. This method easily damages the tires and chassis, and is extremely unsafe, as the cable may break, causing the vehicle to overturn. Traditional vehicle traction devices, such as hub-mounted winches and hydraulic jacks, are not suitable for oversized and overweight special vehicles like those used for transporting wind turbine components. Once a heavy-duty transport vehicle gets stuck, getting it out is extremely difficult and costly, and can cause significant project delays. Summary of the Invention
[0004] To address the aforementioned problems, this utility model provides an extrication device for heavy-duty transport vehicles, which can conveniently and quickly extricate special vehicles transporting heavy wind power components from difficult situations. The technical solution adopted by this utility model is as follows:
[0005] An off-road device for a heavy-duty transport vehicle includes a chassis, a carriage, and a hydraulic push rod. The hydraulic push rod pushes the carriage to slide on the chassis. Several wheels are provided under the chassis. Two laterally extendable telescopic rods I are provided at the front and rear ends of the chassis. Hydraulic outriggers are installed on the telescopic rods I. At least one hydraulic outrigger is provided in the middle of the chassis. The hydraulic outriggers cooperate to extend and retract to raise or lower the chassis.
[0006] The aforementioned off-road device for heavy transport vehicles includes a chassis comprising several crossbeams and several longitudinal beams. The longitudinal beams are provided with slide rails, and several pulleys that cooperate with the slide rails are correspondingly provided below the slide frame.
[0007] The aforementioned get-out device for heavy transport vehicles also includes a telescopic rod II, which is located at the rear end of the carriage, and the hydraulic push rod is located at the front end of the carriage.
[0008] The aforementioned off-road device for heavy transport vehicles has a vehicle body support plate or a tower support plate that can be detachably installed on the slide. The surface of the tower support plate is provided with several shock-absorbing blocks made of rubber or nylon.
[0009] The beneficial effects of this invention are as follows: Depending on the situation of the vehicle stuck on site, this device can be easily moved and lifted to a suitable height using hydraulic outriggers, ensuring stability and safety. It can then be moved out of the stuck location via a sliding frame, improving the efficiency of vehicle removal. For different types of transport vehicles, vehicle body support plates or tower support plates can also be easily installed on the sliding frame. Attached Figure Description

Detailed Implementation
[0015] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings.
[0016] This embodiment is an extrication device for heavy-duty transport vehicles, including a chassis 1, a slide 2, and a hydraulic push rod 3. The hydraulic push rod 3 pushes the slide 3 to slide on the chassis 1. Several wheels 13 are provided under the chassis 1. Two laterally extendable telescopic rods Ⅰ4 are respectively provided at the front and rear ends of the chassis 1. Hydraulic outriggers 6 are mounted on the telescopic rods Ⅰ4. At least one hydraulic outrigger 6 is located in the middle of the chassis 1. The hydraulic outriggers 6 cooperate to extend and retract, raising or lowering the chassis 1. The maximum load of the hydraulic outriggers 6 is at least 50 tons, and the maximum load of the hydraulic push rod 3 is at least 20 tons.
[0017] Specifically, the base frame 1 includes several crossbeams 12 and several longitudinal beams 11. The longitudinal beams 11 are provided with slide rails, and the slide frame 2 is provided with several pulleys 21 that cooperate with the slide rails.
[0018] The aforementioned get-out device for heavy transport vehicles also includes a telescopic rod II5, which is located at the rear end of the carriage 2 and the hydraulic push rod 3 is located at the front end of the carriage 2. When the hydraulic push rod 3 pushes the carriage 2 to move, the telescopic rod II5 also extends and retracts accordingly, playing an auxiliary guiding role and improving the stability of the carriage 2.
[0019] The vehicle body support plate 7 or tower support plate 8 can be detachably installed on the slide 2. For vehicles such as engine nacelles, hubs, and blade transport vehicles, the vehicle body support plate 7 can be bolted to the slide 2. After the vehicle body is lifted using the hydraulic outriggers 6 of this device, the slide 2 moves laterally to escape the obstacle. For tower transport vehicles with a large wheelbase and long length, the tower support plate 8 can ensure the stability of the tower during the escape process and prevent it from rolling off. The surface of the tower support plate 8 is provided with several rubber or nylon shock-absorbing blocks 81 to prevent damage to the tower equipment.
[0020] During the installation phase of wind turbines, wind turbine equipment needs to be transported from the manufacturer to the turbine location using various specialized heavy-duty transport vehicles. These vehicles can carry heavy loads, sometimes weighing tens or even hundreds of tons. If these heavy-duty components become stuck on the wind farm roads and cannot be moved, this device can be used to free them. To use, move the device under the transport vehicle, adjust the position of the telescopic rod I4, activate the hydraulic outriggers 6 to lift the transport vehicle, then activate the hydraulic push rod 3 to move the slide 2, moving the transport vehicle out of its stuck position. Afterward, the hydraulic outriggers 6 retract, the transport vehicle wheels touch the ground, and the device is retracted to complete the freeing operation.
