Technical Field

The invention relates to the technical field of ship piping assembly and disassembly, in particular to a disassembly and assembly tool and a disassembly and assembly method for a flange gasket of a ship piping butt joint pipe.

Background

During ship repair, one section of pipeline in a pipeline system is replaced, butt flanges are arranged on the pipeline system, a mattress (flange gasket) is arranged between the butt flanges, and the butt flanges need to be unfolded by external force during disassembly and assembly so as to be disassembled or assembled into the flange gasket.

Disclosure of Invention

In order to solve the problems, the invention provides a disassembling tool and a disassembling method for a flange gasket of a ship pipe system butt joint pipe, and aims to facilitate the disassembling of the flange gasket of the ship pipe system butt joint pipe. The specific technical scheme is as follows:

the utility model provides a dismouting frock of ship piping butt joint pipe flange gasket, includes a pair of U type pipe clamp subassembly and connects stud between a pair of U type pipe clamp subassembly, connect respectively the top tight nut at stud both ends, U type pipe clamp subassembly includes U type bolt, connects the clamp plate and the gland nut of U type bolt, set up supporting shoe on the clamp plate, be provided with the double-screw bolt mounting hole on the supporting shoe, the during operation the both ends of stud penetrate respectively in the double-screw bolt mounting hole, just top tight nut withstands the supporting shoe.

The working principle of the dismounting tool is as follows: two U-shaped bolts, two pressing plates, a stud and two supporting blocks which are welded on the pressing plates and used as supports are utilized. In the use, utilize clamp plate and two U type bolts to embrace the body to the flange both sides of managing respectively, stud's both ends penetrate in the stud mounting hole of supporting shoe, connect the puller nut at stud both ends and withstand the supporting shoe, use the spanner to pull the puller nut and can make the flange of managing to strut along the axial of body, it can to put into or dismantle to enlarge the flange gasket when the clearance between the flange of managing to the flange.

Above-mentioned dismouting frock compares with the dismouting mode of traditional boats and ships piping butt joint pipe flange gasket, its convenient to use, install and remove efficiently, and solved the difficult problem that the flange gasket can't or the dismouting is extremely difficult under the flat flange butt joint condition of piping.

As one of the preferable schemes of the U-shaped bolt structure, the U-shaped bolt is formed by bending round steel, and the two ends of the round steel are processed with external threads.

As a second preferable mode of the U-shaped bolt structure of the present invention, the U-shaped bolt is formed by bending square steel, and both ends of the square steel are provided with external threads.

The U-shaped bolt formed by bending the square steel has a larger contact area with the pipe body, so that the holding friction force of the U-shaped bolt to the pipe body is increased.

Preferably, both external threads of the U-bolt are formed before the bending.

Preferably, a first mounting groove is formed in one surface, in contact with the pipe body, of the U-shaped bolt, a first brake shoe is glued in the first mounting groove, and the thickness of the first brake shoe is larger than the depth of the first mounting groove.

Preferably, a second mounting groove is formed in one surface, in contact with the tube body, of the pressing plate, a second brake shoe is glued in the second mounting groove, and the thickness of the second brake shoe is larger than the depth of the second mounting groove.

The installation groove is formed in the U-shaped bolt and the pressing plate, the brake shoe is glued in the installation groove, friction force of the U-shaped pipe clamp assembly for clamping the pipe body is further increased, and clamping and dismounting are more reliable.

A dismounting method for a dismounting tool for a flange gasket of a ship pipe system butt joint pipe comprises the following steps:

(1) pre-installing the stud and the jacking nut: two ends of the double-end stud are respectively provided with a jacking nut, and the jacking nuts are screwed to the bottom;

(2) preassembling a U-shaped pipe clamp assembly: a pair of U-shaped pipe clamp assemblies are respectively preassembled on pipe bodies on two sides of the butt joint pipe flange, one U-shaped pipe clamp assembly is fixed with the pipe body, the other U-shaped pipe clamp assembly is loosened with the pipe body and can move, and the inner opening distance of the pair of U-shaped pipe clamp assemblies is larger than the length of the double-end stud;

(3) installing a stud: one end of a double-end stud with a jacking nut at the two ends is inserted into a stud mounting hole arranged on a supporting block of one U-shaped pipe clamp assembly, the other loosened U-shaped pipe clamp assembly is moved to enable the other end of the double-end stud to be inserted into the stud mounting hole arranged on the supporting block of the loosened U-shaped pipe clamp assembly, and then the loosened U-shaped pipe clamp assembly is fixed with the pipe body;

(4) opening the butt joint pipe flange: respectively adjusting the jacking nuts at the two ends of the stud by using a spanner, so that the jacking nuts respectively prop against the supporting blocks on the pair of U-shaped pipe clamp assemblies, and the abutting pipe flanges are spread;

(5) dismounting a flange gasket: and (3) removing the flange gasket between the flanges of the butt joint pipes or installing the flange gasket between the flanges of the butt joint pipes.

The invention has the beneficial effects that:

first, compared with the traditional dismounting method of the flange gasket of the ship pipe system butt joint pipe, the dismounting tool and the dismounting method of the flange gasket of the ship pipe system butt joint pipe have the advantages of convenient use and high dismounting efficiency, and solve the problem that the flange gasket cannot be dismounted or is extremely difficult to dismount under the butt joint condition of pipe system flat flanges.

Secondly, according to the assembling and disassembling tool and the assembling and disassembling method for the flange gasket of the ship pipe system butt joint pipe, the U-shaped bolt formed by bending square steel is adopted, the contact area of the U-shaped bolt and the pipe body is large, and therefore the holding friction force of the U-shaped bolt on the pipe body is increased.

Thirdly, according to the assembling and disassembling tool and the assembling and disassembling method for the flange gasket of the ship pipe system butt joint pipe, the U-shaped bolt and the pressing plate are provided with the installation grooves, and the brake linings are glued in the installation grooves, so that the friction force of the U-shaped pipe clamp assembly for clamping the pipe body is further increased, and the clamping and the assembling and disassembling are more reliable.
