Abstract
A buckling detector comprises a main shaft, multiple sets of main shaft supporting devices mounted on the main shaft, a traction structure mounted at the end of one main shaft supporting device, multiple sets of sealing devices mounted on the main shaft supporting devices and a diameter measuring plate mounted on the main shaft. Each main shaft supporting device comprises two supporting wheel supports oppositely mounted on the main shaft, supporting wheel connecting arms oppositely connected to the corresponding supporting wheel supports in a pivoting mode and a supporting wheel mounted between the corresponding two supporting wheel connecting arms, and thus a symmetrical Y-shaped structure is formed through the connection. A fixing sleeve used for preventing the corresponding two supporting wheel supports from moving back and forth is arranged between the corresponding two supporting wheel supports. A spring is mounted at the front end of each main shaft supporting device. By means of the buckling detector, the overall weight of the structure is greatly reduced, the problem of the risk of falling into a pipeline due to the excessive weight is solved, and more than half offshore construction time is saved.

The purpose of this utility model is realized by following technological scheme:
A kind of Flection detector, it is characterized in that: comprising: a main shaft, be arranged on array main shaft support device on main shaft, be arranged on the hitch structure of a main shaft support device end, be arranged on respectively array seal arrangement on main shaft support device, be arranged on the gauging disc on main shaft, wherein, main shaft support device comprises: be relatively arranged on two support roller bearings on main shaft, be relatively articulated in the support roller link arm on support roller bearing, be arranged on the middle support roller of two support roller link arms, by the above-mentioned herringbone structure that connects and composes a symmetry; Wherein, between two support roller bearings, be provided with one and be used for preventing the fixed muffle that two support roller bearings move forward and backward; The front end of this main shaft support device is equipped with a spring.
Described gauging disc is arranged on the middle part of main shaft by bolt and steel plate, the size of gauging disc is generally the 90%-95% of internal diameter of the pipeline, and, become several parts along its circumference equal dividing, and form zigzag fashion.
Described hitch structure is a swivel joint.
Angle between described two support roller link arms is: 60 ° of-100 ° of scopes.
Described seal arrangement comprises: be arranged on respectively the forward and backward two ends of main shaft protecting sheet, be bolted on several the first rubber pads on protecting sheet; Above rubber pad and protecting sheet, be respectively provided with several apertures, above aperture, be coated with the second rubber pad.
Described support roller bearing is annular steel structure, and support roller link arm is bolted on bearing, between be 120 ° of angles.
The beneficial effects of the utility model: the utility model is owing to adopting technique scheme, it is ensureing under the prerequisite constant to the real-time monitoring effect of bottom pipeline of sea, not only greatly reduce the overall weight of structure, weight loss of weight is nearly 2/3, has solved because weight is excessive, the problem of the ducted risk that easily drops; And save the offshore construction time over half.
Below in conjunction with drawings and Examples, the utility model is described further.
