Problems solved by technology

The hexagonal bolts of hydropower plant equipment have torque requirements. If an adjustable wrench is used to tighten the bolts with a large torque, it is extremely difficult for the bayonets at both ends of the adjustable wrench to fit closely with the outside of the hexagonal bolt, and the opening of the adjustable wrench will have a certain amount of movement. , Using an adjustable wrench to tighten the bolts can easily damage the hexagon of the bolts, making the bolts no longer disassembled. Therefore, it is not allowed to use adjustable wrenches in the maintenance of hydropower plants
[0003] Part of the equipment in the hydropower plant has multiple specifications of hexagonal bolts in a limited space. The maintenance personnel need to carry multiple specifications of open-end wrenches, which is inconvenient to carry, and because there are many tools brought into the limited space, it is easy for tools to be left inside the equipment. Once the equipment rotates, it will inevitably cause equipment damage

Abstract

The invention discloses a multifunctional open spanner which comprises a spanner body with an opening part and a plurality of plug pieces. The open part is of a U-shaped structure with a first side wall and a second side wall which are opposite to each other, the plug pieces are parallel to the first side wall and located between the first side wall and the second side wall, and one end of each plug piece is rotationally connected to the bottom of the U-shaped structure of the opening part. The multifunctional open spanner aims at overcoming the defects in the prior art, and the open spanner capable of adjusting the size of an opening is provided and is suitable for overhauling equipment of a hydraulic power plant.

Description

technical field [0001] The invention relates to a multifunctional open-end wrench. Background technique [0002] At present, the hexagonal bolts used for fastening equipment in hydropower plants are all standard parts, and it is required to use an open-end wrench that completely matches the size of the bolts during equipment inspection and maintenance. The hexagonal bolts of hydropower plant equipment have torque requirements. If an adjustable wrench is used to tighten the bolts with a large torque, it is extremely difficult for the bayonets at both ends of the adjustable wrench to fit closely with the outside of the hexagonal bolt, and the opening of the adjustable wrench will have a certain amount of movement. , Using an adjustable wrench to tighten the bolt can easily damage the hexagon of the bolt, making the bolt no longer disassembled. Therefore, an adjustable wrench is not allowed in the maintenance of hydropower plants. [0003] Part of the equipment in the hydropow...
