Abstract

The utility model relates to a chord liner welding tool, which includes a positioning device and bolts for clamping; the positioning device is in the shape of an inverted isosceles trapezoid, and its two waists extend upward and are bent outward to form a chord that is convenient for hooking and clamping. The hooks on both sides of the lining of the chord tube; there are threaded holes vertically at the intersection of the hook and the two waists of the positioning device; the bolts are screwed into the threaded holes and cooperate with the hooks to clamp the chord and the chord Liner; the two waists of the positioning device are respectively parallel to the planes on both radial sides of the chord liner; the end of the hook has a protrusion that contacts the outer wall of the chord. The utility model has the advantages of avoiding the spot welding link through the use of tooling, eliminating the defects that are prone to occur in spot welding, canceling welding preheating and other links, reducing energy consumption, and changing the rack assembly from 3 people to 2 people. Human cooperation improves work efficiency and quality stability and reduces production costs.

Description

A chord liner welding tool

technical field

The utility model relates to a chord liner, in particular to a chord liner welding tool.

Background technique

With the accelerated pace of ocean development, the development prospects of the ocean engineering equipment industry are getting brighter and brighter. In the offshore engineering equipment industry, the technical level of the drilling platform is the highest. The main coil of the offshore platform leg is the key component of the jack-up offshore drilling platform, mainly including the rack in the middle and the semicircular chords on both sides of the rack. , the chord and the rack are welded and fixed, and the inside of the chord is welded with a liner.

The traditional leg chord liner assembly is assembled by spot welding. When assembling the liner, a drying gun is required to pre-heat the spot welding position and three people are required to cooperate to complete the liner spot welding. This method consumes a lot of energy, requires many people to cooperate to complete, and the work efficiency is low, and the quality cannot be guaranteed.

Utility model content

The technical problem to be solved by the utility model is to provide a chord liner welding tool for the main spinning pipe of the pile leg of an offshore platform with low energy consumption, high work efficiency and stable quality.

In order to solve the above technical problems, the technical solution of the present utility model is: a chord liner welding tool, the innovation point of which is that it includes a positioning device and bolts for clamping; the positioning device is in the shape of an inverted isosceles trapezoid, and its The two waists extend upwards and bend outwards to form a hook-shaped body that is convenient for hooking the two sides of the chord and the chord liner; the hook-shaped body and the two waists of the positioning device have threaded holes at the junction; the bolts are screwed into the threaded holes And it cooperates with the hook to clamp the string tube and string pad.

Further, the two waists of the positioning device are respectively parallel to the planes on both radial sides of the chord liner.

Further, the end of the hook has a protrusion in contact with the outer wall of the chord.

Further, several chord liner welding tools are installed on the chord.

The utility model has the advantages of:

(1) Through the use of tooling, spot welding is avoided, defects that are prone to spot welding are eliminated, welding preheating and other links are canceled, energy consumption is reduced, rack assembly is changed from 3-person collaboration to 2-person collaboration, and the improvement is improved. Improve work efficiency and quality stability, reduce production costs.

(2) The radial sides of the chord liner are made into planes with an inclination angle, and the corresponding two sides of the tooling are also inclined, which is convenient for the installation of the tooling and the installation and fixation of the chord liner.

(3) The tooling is firmly clamped and is not easy to vibrate and fall off, and has little damage to the surface of the chord.

(4) The tight fit of the tooling ensures the position accuracy requirements of the chord and chord liner during welding.
