Description
Technical Field
The utility model relates to the field of airplane ground support equipment, in particular to a novel airplane double-wheel chock tool.
Background
When the airport is used for storing the airport apron in the open air, in order to avoid the airplane from moving due to the influence of strong wind and strong rain, wheel blocks are required to be arranged on the front wheel and the rear wheel of the nose landing gear, meanwhile, in order to ensure that the front wheel block and the rear wheel block are kept to be attached to the airplane wheel and not to shift, a limiting lock is required to be arranged on the front wheel block and the rear wheel block, the limiting lock is connected with the front wheel block and the rear wheel block to relatively lock the distance between the front wheel block and the rear wheel block, and therefore the airplane wheel is ensured not to move due to the influence of strong wind and strong rain. As shown in fig. 1, most of the wheel chock 100 and the limit lock in the market are manufactured independently and are two sets of devices independent from each other, and a common limit lock is a U-shaped lock 200, and the U-shaped lock 200 is used in cooperation with a binding rope 201. When the wheel fender 100 is used in an actual working condition, the wheel fender 100 is lifted out of a warehouse through the lifting rope 101 arranged on the wheel fender 100, the wheel fender 100 is arranged on the front wheel and the rear wheel, then the two ends of the metal rod of the U-shaped lock 200 are inserted into the insertion holes in the side face of the wheel fender 100, so that the front-rear distance between the front wheel fender 100 and the rear wheel fender 100 is locked, then the left U-shaped lock 200 and the right U-shaped lock 200 are bound through the binding rope 201, the left-right distance between the two U-shaped locks 200 is further locked, and thus the wheels between the front wheel fender 100 and the rear wheel fender 100 and between the left U-shaped lock 200 and the right U-shaped lock 200 cannot move due to the influence of strong wind and strong rain.
However, the manufacturing cost or purchasing cost of the U-shaped lock made of the metal material is high independently, the U-shaped lock cannot be used for freely adjusting the installation distance from front to back and from left to right, the U-shaped lock is not suitable for locking wheels of different types and different sizes, a limit lock needs to be designed for each type, each aircraft needs at least 12 wheel chock limit locks, the required number is large, the weight is heavy, the movement is inconvenient, a large storage field is occupied, large workload is brought to workers, and the efficiency of relevant work of wheel locking is low.
Meanwhile, after the airplane stops at the airport, the two airplane wheels of the nose landing gear deflect slightly, and the common wheel blocks on the market cannot be attached to the two airplane wheels independently, so that the unstable airplane wheels are caused sometimes.
