Description

TECHNICAL FIELD

[0001] The present application belongs to the field of offshore ship design and construction, and particularly relates to a kind of adjustable device for conveniently and quickly measuring ship body baseline deflection. BACKGROUND

[0002] After the completion of the whole ship forming in the ship dock, the baseline deflection data of the center of the ship bottom is measured, and a vertical channel steel part is set in advance at the center of the ship bottom. During the measurement process, a level is used to draw a horizontal reference line on each channel steel part, and the value of each line and the center of the ship bottom is measured. During the process of drawing the horizontal line, the level needs to be moved more than 15 times, and multiple reference height points need to be repeatedly drawn. According to the height points, the horizontal line at the next position is drawn. Before the construction, the operator needs to set the channel steel part at the corresponding position in advance, and then use the level to draw the horizontal line of the first channel steel part. The first point needs to be at the center of the ship bottom with an integer height, and then set the height reference point of the visible position of the instrument. The instrument needs to be moved multiple times until all the horizontal lines of the channel steel parts at the center of the ship bottom are drawn. During the construction, the reference horizontal point is repeatedly corrected to ensure the reliability of the data. The above construction needs more than three people to complete the construction operation. Sometimes, the data is not up to standard due to instrument or human error, and the instability of the channel steel part causes errors at both ends of the horizontal line, which increases the data error. At present, in the process of measuring the baseline deflection at the center of the ship bottom, the ship owner requires more strict data, which is directly related to the data of the ship water gauge and the main ship body type depth. At the same time, the channel steel part method is too backward, the stability is poor, the cost is too high, the steel part needs to be replaced for each ship, the instrument needs to be moved multiple times for construction, and the precision is not high, which seriously affects the precision and quality of the measurement construction, and slows down the construction period. In order to achieve the precision data detection of the baseline deflection at the center of the ship bottom without using the channel steel part, a device that meets the precision requirements of the present stage is needed to replace the previous steel part, and the existing resources and technical systems are optimized to achieve a large precision improvement. Therefore, the auxiliary device is designed. The use of the device for measuring the precision data of the baseline deflection at the center of the ship bottom can greatly improve the data precision, greatly improve the measurement construction efficiency, and greatly facilitate the measurement construction, and realize the one-time feedback of the baseline deflection precision data.

[0019] An adjustable device for convenient and rapid measurement of hull baseline deflection, such as Figure 1 , 2 As shown, there is a long, rod-shaped main board made of acrylic material. One end of the main board is fitted with a U-shaped caliper, and the other end is fixed with a full-size target. The U-shaped caliper consists of a scale with graduations on both sides and a connecting plate connecting the scales. The scale surface has graduations, and there are two rectangular cover plates at the top of the scale. Two button magnets are set in the middle of the cover plates, and a long rod screw is set at the bottom of the cover plates. The long rod screw is screwed into the scale from the top downwards. The dimensions of the connecting plate are 1000mm long, 50mm wide, and 8mm thick.

[0020] Two clamping sleeves are symmetrically fixed at one end of the main board. The clamping sleeves are fitted with screw rods. The clamping sleeves have grooves. The distance between the two clamping sleeves is the same as the width of the U-shaped caliper. The scales on both sides of the U-shaped caliper are inserted into the grooves of the clamping sleeves. Tighten the screw rods to press against the scales.

[0021] The screw rod is φ10mm in size, the distance between the two clamping sleeves is 2mm greater than the width of the U-shaped caliper, and limit blocks are set at the top of the scale and below the cover plate.

[0022] like Figure 3 As shown, when using this device, the main structure is attached to the outer bottom center of the hull. Loosen the clamping sleeve on the device and align the connection between the main board and the scales on both sides with the same scale point 9. Then tighten the screw rod. Check if the horizontal bubble on the transverse rod is in the center. If not, make fine adjustments in the up-down direction by rotating the rectangular cover plate on either side of the upper part of the structure until the horizontal bubble is in the center. The scales on the other devices at the center of the hull's outer bottom are consistent with the scale data of the first device. Then, use a laser total station set up at the visible full-size target of all devices, approximately at the center of the main hull, to perform precision measurements, and then read and record the data.

[0023] The structure top is provided with a button magnet, which can be smoothly adsorbed on the ship body, and the two sides of the connecting plate are provided with scales, the main plate is provided with a clamping sleeve, so that the U-shaped caliper can be freely moved up and down horizontally, and the horizontal height data of the device can be freely adjusted.
