CN207710161U - A kind of Tower crane standard section main chord welding tooling - Google Patents

Abstract

The utility model relates to a main chord rod welding tool for a standard section of a tower crane. At present, the main chord of the standard section is assembled first and then welded. The traditional welding process is troublesome because it cannot be moved and rotated. The utility model comprises two symmetrically arranged bases, the base is provided with a turret main body, the middle part of the turret main body forms a hollow part for placing the main chord of the standard section, and the upper part of the hollow part is provided with a turret flap . The turntable flap is connected to the main body of the turntable through a pin shaft. The utility model connects the main chord of the standard section with the main body of the turntable with a pin shaft, and performs welding after the installation is completed. During the whole welding process, the angle can be freely rotated within 360°, and the operation is flexible.

Description

A main chord welding tool for a standard section of a tower crane

technical field

The utility model relates to a main chord rod welding tool for a standard section of a tower crane.

Background technique

At present, the main chord of the standard section is assembled first and then welded. The traditional welding cannot be moved and rotated, so the welding process is troublesome; turning over is also a waste of time. During the welding process, there is also the problem of the angle of the weld bead, which must be turned over by a crane. During the welding process, the mounting holes on both sides are not positioned. After the welding is completed, due to welding shrinkage, it will have a certain impact on the tailor welding of the standard joint.

Utility model content

Aiming at the problems existing in the prior art, the utility model provides a main chord welding frock for a standard section of a tower crane, which reduces the use of the crane due to flipping welding, and can be directly welded on the frock, which can be removed after welding, which improves the work efficiency. efficiency.

For this reason, the utility model discloses a main chord welding tool for a standard section of a tower crane, which is characterized in that it includes two symmetrically arranged bases. The hollow part of the main chord of the standard section, and the upper part of the hollow part is provided with a turntable flap.

The turntable flap is connected to the main body of the turntable through a pin shaft.

The upper end of the base forms an arc-shaped inner concave surface, and the outer arc-shaped surface of the main body of the turntable abuts against it.

The utility model connects the main chord of the standard section and the main body of the turntable with a pin shaft, and performs welding after the installation is completed. During the whole welding process, the angle can be freely rotated within 360°, and the operation is flexible. The beneficial effect of the utility model is that it can ensure that the size of the main chord is not deformed, facilitate the welding of the web, and can rotate 360° for welding, which greatly improves the production efficiency while ensuring the size requirement.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in detail.

As shown in Figure 1-2, a main chord welding tool for a standard section of a tower crane includes two symmetrically arranged bases 1, on which a turret main body 2 is arranged, and the middle part of the main chord of the turret is formed to place the main chord of a standard section. 4, the top of the hollowed out portion is provided with a turntable turnover plate 5. The turret turnover plate 5 is connected to the turret main body 2 through the pin shaft 3 . The upper end of the base forms an arc-shaped inner concave surface, and the outer arc-shaped surface of the main body of the turntable abuts against it.

In the utility model, the main body of the turret is firstly placed on the base, and then the main chord of the standard section is hoisted onto the turret, and then the turning plate is covered, and the turning plate and the main body of the turret are locked with a pin shaft, and then pressed Tighten the main chord 4, and perform welding after installation. The angle can be rotated freely during the whole welding process, and the operation is flexible. After the welding is completed, the bearing pin is removed, the turntable flap 5 is unclamped, and the main chord of the standard section is hung out with a crane.

The above is only a preferred embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any person familiar with the technical field can easily think of All changes or replacements should fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope of the claims.
