Description

Pipeline connection flange bolt removal tool

technical field

The utility model belongs to the technical field of bolt disassembly and assembly aids, in particular to a pipeline connection flange bolt disassembly tool.

Background technique

Flanges are the connecting parts of pipelines, and the pipeline connection flanges are usually fixedly connected together by bolts and nuts. When disassembling bolts on site, tools such as adjustable wrench, ring wrench, open-ended wrench, socket wrench and other tools are often used, and two wrenches are needed to disassemble them. Only hold a wrench to disassemble the nut. The bolt head and the nut are respectively placed on the upper and lower ends of the flange, and the two wrenches are placed on the upper and lower ends of the flange. The direction of force is opposite. Especially when the flange is in a special position, the wrench is not easy to install. It is difficult to rotate in place, therefore, it is very inconvenient to disassemble and assemble the flange with the existing wrench, not only the operation is labor-intensive, but also the work efficiency is low.

Utility model content

The purpose of the utility model is to provide a pipeline connection flange bolt dismounting tool which can conveniently, safely and quickly disassemble the flange bolts.

The technical solution adopted to realize the purpose of this utility model is: the tool includes a fixed rod frame, a fastening handle, a reversing handle and a movable sleeve, wherein the fastening handle is a horizontal rod, and the front end of the horizontal rod is welded with The sleeve chuck, the fixed rod frame is a vertical rod, the upper end of which is connected with the fastening handle set through the cylinder sleeve, the lower part is provided with a sliding member and a fixed member, and a fastening spring is installed between the two members. There is a threaded hole on one side, and the lower chuck is connected through the thread. The reversing handle is an S-shaped rod structure, which is connected to one side of the fastening handle through a pin shaft. Block, between the reversing handle and the fastening handle near the magnetic block, there is a limit short joint, and a return spring is installed on the short joint.

The movable sleeve is a set of sleeves with inner holes of different specifications, and the inner holes are paired square or square or hexagonal or octagonal through holes, and the outsides are all hexagonal prisms with the same size.

The inner hole of the sleeve chuck is in the shape of a hexagonal hole matched with the outer hexagonal prism of the movable sleeve, and the outer part is circular or polygonal.

The lower chuck is a set of sleeve chucks with inner holes of different specifications. There is a threaded rod connected to the sliding sleeve on one side of the chuck. The inner hole of the lower chuck is a hexagonal hole that is connected with a bolt or a nut. shape, and the outside is circular or polygonal.

The sliding member is a hexagon with an inner diameter slightly larger than the outer diameter of the fixing rod frame, and can freely slide up and down along the fixing frame.

The pipeline connection flange bolt removal tool made according to the above scheme realizes the function of safe and quick disassembly or fastening of flange bolts, which changes the situation that two wrenches must be used to operate with both hands at the same time when using ordinary wrenches, and improves work efficiency. , reducing labor intensity. It has the advantages of convenient operation, saving time and effort, safety and reliability.

Detailed ways

Referring to Fig. 1, the pipeline connection flange bolt disassembly tool of the present utility model includes a fixed rod frame 1, a fastening handle 2, a reversing handle 3 and a movable sleeve 10, wherein the fastening handle 2 is a horizontal rod The front end of the horizontal rod is welded with a sleeve chuck 4, the fixed rod frame 1 is a vertical rod, the upper end of which is connected with the fastening handle 2 through a cylindrical sleeve 1-1, and the lower part is provided with a sliding member 7 and a fixed Component 13, a fastening spring 9 is installed between the two components, a threaded hole is provided on one side of the sliding component 7, and the lower chuck 8 is connected through the thread, the reversing handle 3 is an S-shaped rod structure, and the pin shaft 11 Connected to one side of the fastening handle 2, a magnetic block 6 is inlaid on the front end of the reversing handle 3, and a limit joint is set between the reversing handle 3 and the fastening handle 2 near the magnetic block 6 12. The return spring 5 is installed on the nipple. The movable sleeve 10 is a set of sleeves with inner holes of different specifications, the inner holes of which are square or square or hexagonal or octagonal through holes, and the outsides are all hexagonal prisms with the same size. The inner hole of the sleeve chuck 4 is in the shape of a hexagonal hole that is connected with the hexagonal prism outside the movable sleeve, and the outside is circular or polygonal. The lower chuck 8 is a set of sleeve chucks with inner holes of different specifications. On one side of the chuck, there is a threaded rod connected with the sliding sleeve 7. The inner hole of the lower chuck 8 is connected with a bolt or a nut. The hexagonal hole is round or polygonal in shape.
