Description

Technical Field

[0001] This invention relates to a maintenance tool, specifically a combined maintenance tool for apron hydrant wells, belonging to the field of pipeline equipment technology. Background Technology

[0002] Apron hydrants are typically located on the apron and are used to install refueling hydrants. These hydrants connect to the aircraft's fuel tanks via a refueling truck, enabling refueling. It is a crucial component of the apron refueling system and is essential for ensuring on-time performance and flight safety.

[0003] Airfield hydrant wells typically have two types of bolts: hydrant well bolts and fusible valve bolts. Since these bolts vary in size, different sized wrenches are required for each type of maintenance. Tightening these bolts necessitates manual labor, requiring manual entry into the well each time. Furthermore, some airfield hydrant wells have narrow interiors, making operation difficult. Therefore, wrenches with extension rods are needed. However, carrying a large number of integrated extension wrenches is inconvenient due to their weight. This application proposes a combined maintenance tool for airfield hydrant wells. Summary of the Invention

[0004] The purpose of this invention is to provide a combined maintenance tool for apron hydrant wells to solve the aforementioned problems. During use, when operating the hydrant well bolts, first select a hydrant well bolt wrench of the corresponding size, and then select either a first or second quick-connect rod based on the distance from the ground to the equipment in the hydrant well. Connect the hydrant well bolt wrench and rotating rod to it. At this point, the rotating rod can be rotated on the ground, causing the hydrant well bolt wrench to rotate and thus operate the hydrant well bolt. When the rotating rod cannot rotate the hydrant well bolt, remove the rotating rod and replace it with a torque wrench. The long torque of the torque wrench allows for relatively easy rotation. When operating the fusible valve bolts, select a fusible valve bolt wrench of the corresponding size and repeat the above actions to achieve the corresponding operation of the fusible valve bolts. Simultaneously, the parts storage unit can store unused, non-standard sized parts, thereby reducing the carrying weight through the combined connection method and greatly reducing manual labor intensity.

[0005] The present invention achieves the above-mentioned objectives through the following technical solution: a combined maintenance tool for apron hydrant wells, comprising a toolbox, the toolbox including a box body and a box cover, the box cover being rotatably disposed above the box body, the box body containing a torque wrench, a first quick-connect rod, a second quick-connect rod, a rotating rod, multiple fusible valve bolt wrenches, multiple hydrant well bolt wrenches, and a parts storage unit; the multiple fusible valve bolt wrenches are adaptable to fusible valve bolts of different diameters, and the multiple hydrant well bolt wrenches are adaptable to hydrant well bolts of different diameters.

[0020] The beneficial effects of this invention are:

[0021] During use, when operating the well bolts, first select the appropriate size well bolt wrench, and then choose either the first or second quick-connect rod based on the distance from the ground to the equipment in the well. Connect the well bolt wrench and rotating rod to the wrench. From the ground, rotate the rotating rod to turn the well bolt wrench and operate the bolt. If the rotating rod cannot turn the bolt, remove it and replace it with a torque wrench. The long torque of the torque wrench allows for easier rotation.
