Description

area of utility model

The utility model relates to a device for detecting damage to complex steel structures.

State of the art

As China continues to invest in offshore wind farm construction, offshore wind farm construction has also entered a period of rapid development, and these projects have played an important role in reviving the national economy and ensuring urban security. During decades of development, the offshore wind farms built early have now entered the maintenance phase, and with time, more and more offshore wind farms have entered the maintenance phase. When checking the steel structure of an offshore wind farm, the testing effort is large and the steel structure is complex. China has always lacked experience in monitoring and inspecting steel structures in offshore wind farms, and the level of inspection and technical equipment is relatively backward, far from meeting the demands of increasingly complex steel structures and increasing damage detection Meet steel structures in offshore wind farm. Therefore, from an economic and social point of view, it is important to research and develop simpler devices that can also be used to inspect complex steel structures.

Content of the utility model

The utility model overcomes the deficiencies of the prior art and provides a device for detecting damage to complex steel structures.

In order to solve the above technical problems, this utility model uses the following technical solution: a device for detecting damage to complex steel structures, which includes a display control device, a cable, a handle, a telescopic rod and an error checking head, the display control device is provided with a holding element for the telescopic rod on one, e.g attached to the top of the support member and the flaw inspection head is attached to the top of the telescopic rod.

To use the above technical solution: When the device is used for detection, the user first adjusts the length and angle of the telescopic rod to fit the complex steel structure system, and then attaches the flaw detection head to the tip of the telescopic rod and holds the handle to perform the test.

One, e.g. left, side of the display control device is provided with a holding element for catching the telescopic rod, and the holding element is provided with a recess adapted to the shape of the telescopic rod.

The handle is mounted on one side (e.g. left side) of the device and the telescopic rod is mounted on the other side (i.e. right side).

There are three telescopic rods or sections, the upper telescopic rod is provided with a retaining element above the upper telescopic rod, the upper telescopic rod is connected to the central telescopic rod by a pivot joint, and the lower end of the telescopic rod is pivoted on the left side of the display controller .

The error checking head attaches to the top of the telescopic pole.

Compared with the prior art, the utility model has the following advantageous effects: the device is simple in structure, easy to carry, easy to adjust in height and angle to adapt to various shapes of steel structures; the device can also handle large steel structures with complex structural shapes.

Embodiments of the invention

Specific versions of the utility model are described below using the figure ( 1 ) and examples are described in more detail. The following examples serve to illustrate the utility model, but are not intended to limit the scope.

As in 1 shown, a complex device for detecting damage to steel structures consists of: display control unit 1, cable 2, handle 3, telescopic rod 4 and error checking head 5, the handle 3 being attached to one, e.g. right, side of the display control unit 1 . A holding member 6 is attached to the other, ie left, side of the display controller 1 . The size of the slot of the limit switch 6 on the left side of the display controller is adapted to the shape of the telescopic rod 4.

The error checking head 5 is electrically connected to the inside of the display controller 1 .

There are three telescopic rods 4 or sections thereof that can be adjusted in the embodiment. The lower end of the lower telescopic rod 4 is pivotally connected to the display controller 1, and the lower telescopic rod 4 is provided with a hole (limit hole). And the lower end of the middle telescopic rod 4 is provided with an elastic retainer, which snaps into the limit hole when the telescopic rod 4 is extended. The lower end of the upper telescopic rod 4 and the upper end of the middle telescopic rod 4 are connected by a swivel joint 7 . The swivel joint 7 is movably connected to the mounting sleeve and is free to rotate on either side with the center of the joint. When using the device, first the swivel joint 7 is attached to the upper end of the telescopic rod and then the angle on the other side is adjusted and the lower end of the telescopic rod is attached to the swivel joint 7 . At the upper end of the telescopic rod 4 there is a (further) holding element 8 with a slot which is adapted to the size of the upper part of the flaw detection head 5 .

When using the device for inspection, the length and angle of the telescopic rod 4 can be adjusted to deal with a steel structure of complex shape or structure and facilitate the personnel's inspection of the steel structure.

The utility model discloses a device for detecting damage to complex steel structures, which relates to the field of damage detection to steel structures. The device consists of the display controller, the cable, the handle, the telescopic rod and the error checking head. For example, the telescopic pole support member is installed on the left side of the display controller, and the handle and telescopic pole are provided on either side of the display controller, respectively, the telescopic pole being adjustable in length and angle; the fixture for the flaw inspection head is mounted on top of the telescopic pole and the flaw inspection head can be attached to the top of the telescopic pole. The device of this utility model for detecting damage to complex steel structures is simple in construction, portable and can be easily adjusted in height and angle to complex shapes of steel structures.
