Description

Technical Field

[0001] The utility model relates to the technical field of ship detection equipment, in particular to a vertical weld detection device. Background Art

[0002] At present, there are many ultrasonic non-destructive testing equipment on the market, but most of them are handheld non-destructive testing equipment, and some are three-axis ultrasonic non-destructive testing equipment platforms. In the current ultrasonic non-destructive testing technology for ship welds, due to the large size of the ship, the ends of the butt joint plate welds cannot be fully scanned by handheld equipment, the work efficiency is low, and the working time of the staff is increased. This is far from meeting the current requirements of people for this product.

[0003] Ships are large in size and the height of vertical welds exceeds the range of manual inspection, so a device that can perform high-altitude vertical weld inspection is needed. Utility Model Content

[0004] In view of the above problems, a vertical weld detection device is now provided to solve the problems existing in the prior art.

The radiation detection device is arranged on the side of the vertical descent component facing the weld. When the vertical release component is installed at a high place, the vertical descent component fits the vertical weld. As the vertical release component is continuously released, the vertical descent component descends vertically along the weld. When the vertical descent component reaches a position to be detected, it stops and detection is performed.

[0007] The above-mentioned vertical weld detection device also has the following characteristics: the vertical release assembly includes an L-shaped support frame and a release portion, the release portion is arranged on the horizontal plate of the support frame, and the installation and fixing portion is arranged on the vertical plate of the support frame. When the vertical plate of the support frame fits the ship railing, the installation and fixing portion can cooperate with the ship railing, and a through hole is provided on the horizontal plate of the support frame for the release end of the release portion to pass through. The release end of the release portion passes through the through hole and is connected to the vertical descending assembly.

[0008] The beneficial effects of the above scheme are as follows: the support frame can be fixed on a high-place railing by installing the fixing part, and the vertical descending assembly can be vertically descended from a high place by the releasing part to detect the vertical weld.

[0009] The above-mentioned vertical weld detection device also has the following characteristics: the release part includes a shell, a drive motor, a reduction gear and a winding drum; the shell is installed on the horizontal plate of the support frame, and an opening is provided at the bottom of the shell, and the shell opening is opposite to the through hole; the drive motor, the reduction gear and the winding drum are all arranged in the shell, and the power end of the drive motor is connected to the winding drum through the reduction gear, and one end of the traction rope on the winding drum passes through the opening of the shell and the through hole and then is connected to the vertical descent assembly.

[0010] The beneficial effects of the above scheme are as follows: the driving motor drives the winding drum to rotate through the reduction gear to drive the vertical descending assembly to rise or fall, so that it can move along the weld to detect the weld.

[0011] The above-mentioned vertical weld detection device also has the following characteristics: the installation and fixing part includes a telescopic rod, a hook and a knob; a telescopic groove is provided on one end surface of the horizontal plate of the support frame; the telescopic rod is arranged in the telescopic groove; when the telescopic rod slides along the telescopic groove, it can extend or retract into the telescopic groove; the hook is arranged on one end surface of the telescopic rod extending out of the telescopic groove; a threaded hole is provided on the side wall of the telescopic groove extending to the top surface of the horizontal plate of the support frame; the knob is arranged in the threaded hole; when the knob is fully screwed into the threaded hole, the knob is pressed against the side wall of the telescopic rod.

[0012] The beneficial effect of the above scheme is that the hook head can be hooked on different railings by adjusting the distance that the telescopic rod extends out of the telescopic slot, and the telescopic rod is positioned by the knob to achieve the effect of fixing the support frame on different railings.

[0013] The above-mentioned vertical weld detection device also has the following characteristics: the vertical descent assembly includes a vehicle body and a counterweight, the counterweight is arranged in the vehicle body, one end of the traction rope is connected to the vehicle body as a release end, and the radiation detection equipment is embedded in the central position of the bottom of the vehicle body. When the support frame is installed on the ship railing and the four wheels of the vehicle body are on both sides of the weld to be detected, the radiation detection equipment is facing the weld, and the traction rope is in an inclined state at this time.

[0014] The beneficial effect of the above scheme is that since the upper part of the traction rope is close to the wall and the lower part is far away from the wall, the vehicle body can always fit the wall under the action of its own gravity and the gravity of the counterweight block, so the X-ray detection equipment can always be aligned with the weld.

[0015] In summary, the beneficial effects of this scheme are:

[0016] In the vertical weld detection device provided by the utility model, the support frame and the installation fixing part cooperate with each other so that the support frame is installed on the high railing, and the release part allows the vehicle body and the ray detection equipment thereon to be lowered from a high place along the weld to detect the weld.
