Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of dynamic calibration devices, in particular to a ship ladder straight line dynamic calibration device. BACKGROUND

[0002] In the process of ship manufacturing and maintenance, the straightness of the ladder is crucial for the safe passage of personnel and goods, and the straight line dynamic calibration of the ship ladder refers to real-time measurement, evaluation and adjustment of the straightness of the ladder during ship navigation to ensure that the ladder always maintains a straight state that meets safety and use requirements in a dynamic environment. Since the ship will sway and vibrate due to various factors such as sea waves and wind during navigation, the ladder will also produce dynamic deformation. The purpose of straight line dynamic calibration is to timely discover and correct these deformations to ensure the safety of personnel going up and down the ladder and the smooth operation of related operations.

[0003] At present, in the actual use process, the calibration of the ship ladder mainly relies on manual static measurement using simple measuring tools. This method is not only inefficient, but also difficult to accurately reflect the dynamic straightness of the ladder during actual ship navigation, resulting in a large error in the calibration result. In addition, the ship will produce rolling, pitching and heaving movements due to sea waves during navigation, which will cause dynamic load on the guide rail and adjusting block of the ladder, resulting in changes in the straightness of the ladder and affecting the straight line dynamic calibration of the ladder. Secondly, static measurement cannot accurately reflect the dynamic straightness of the ladder during actual ship navigation. Static measurement is performed when the ship is in a relatively static state, and cannot capture the real-time deformation of the ladder due to dynamic load during ship navigation, which results in a large error between the calibration result and the straightness of the ladder in the actual use state, and cannot provide reliable basis for the safe use of the ladder.

[0004] Therefore, the present application proposes a ship ladder straight line dynamic calibration device to solve the problem that the traditional straight line dynamic calibration device cannot capture the real-time deformation of the ladder due to dynamic load during ship navigation when using static measurement, thereby affecting the calibration result of the ladder and the straightness measurement error, and improve the accuracy and efficiency of the calibration of the ship ladder.

At this time, the slide bar 43 is limited by the sealing plate and moves inside the symmetrical curved groove 430. At this time, the convex ring 431 connects the slide bar 43 to move toward one side of the sealing plate. The spring 1 432 is compressed and deformed by the convex ring 431, and at this time the slide bar 43 drives the push plate 433 to move outward. It should be noted that the inner surface of the push plate 433 is connected to one end of the piston rod, thereby driving the piston member 453 as a whole to move toward the side away from the ball 42. Figures 16-17 As shown, after the piston 453 moves away from the sponge plug 454, the oil inlet hole 450 is opened. At this time, the lubricating oil inside the oil storage cylinder 44 enters the inner cavity of the abutting column 45 through the oil inlet hole 450, gradually infiltrating the sponge plug 454. The sponge plug 454 transfers the lubricating oil, which overflows through the center hole 4510. During the rolling process of the ball 42, the lubricating oil comes into contact with the sponge plug 454, thereby achieving the smearing of the lubricating oil on the surface of the ball 42. It is also worth noting that after the lubricating oil is squeezed out, the ball 42 is lubricated, thereby reducing the friction resistance of the contact between the slide 41 and the guide rail 21. On the other hand, the lubricating oil can also play a cooling role. After cooling, the temperature of the expansion column 452 drops and gradually shrinks. At this time, the slide rod 43 is no longer affected by the resistance of the expansion column 452. Then, the piston part 453 is reset under the reverse elastic force of the spring 1 432 and the spring 2 434. The piston moves toward the side of the sponge plug 454 again to block the oil inlet hole 450 and exert a certain resistance pressure on the sponge plug 454, so that the saturated lubricating oil of the sponge plug 454 is squeezed out from the center hole 4510 and the flow equalizing hole 4511 to achieve uniform lubrication of the ball 42. Through the above settings, the wear and aging of the slide 41 and the guide rail 21 can be reduced, the jumping, jamming and other phenomena of the slide 41 during the sliding process can be reduced, and the accuracy of the linear dynamic calibration of the inclined ladder can be improved.

[0024] The working principle and use process of the present application are as follows: in actual use, first, the hoisting assembly is installed on the upper end of the ship body, one end of the ship ladder 1 is movably connected with the ship body, the straight line calibration mechanism is arranged on both sides of the ship ladder, the laser calibration instrument 3 is used to detect the sliding interval of the sliding calibration assembly on the guide rail 21 in real time, so that the sliding calibration assemblies 4 on both sides of the ship ladder 1 maintain the same horizontal parallel position, and the straightness of the ship ladder 1 is measured, evaluated and adjusted in real time; then, when the laser calibration instruments 3 on both sides of the ship ladder 1 monitor that the sliding seats 41 on both sides are not in the same horizontal position, instructions are sent to the forward and reverse motor 12 and the winding part, the output shaft of the forward and reverse motor 12 drives the shaft rod 13 to rotate after receiving the instructions, the curved rod 14 drives the curved rod 14 to move around the central axis of the shaft rod 13, the inner gear ring 111 on the inner side of the conical operation cylinder 11 is matched with the surface teeth of the movable gear 15, the movable gear 15 moves in a circle, the convex column 151 moves in the inner side of the annular plate 16 under the double limiting action of the reserved sliding groove 20 and the annular plate 16, drives the connecting plate 17 and the limiting sliding block 171 to move horizontally, thus drives the sliding seat 41 to move on the surface of the guide rail 21, and the direction of the sliding seat 41 is controlled by the clockwise and counterclockwise directions of the forward and reverse motor 12, so that the sliding seat 41 on both sides of the ship ladder 1 is always adjusted to the same horizontal position, the parallelism of the sling is ensured, and the stable state of the ship ladder 1 is realized; when the sliding seat 41 and the side plate 411 move on the surface of the guide rail 21, the ball 42 rolls on the lubricating arc groove 210 opened on the surface of the guide rail 21, after the device is used for a period of time, the lubricating oil on the surface of the ball 42 is consumed, and then the resistance friction is increased, at this time, heat transfer makes the expansion column 452 expand, when the two groups of expansion columns 452 expand, the one end of the sliding rod 43 is touched, at this time, the sliding rod 43 moves in the inner side of the symmetrical bending groove 430 under the limiting action of the sealing plate, at this time, the convex ring 431 moves to the side of the sealing plate connected with the sliding rod 43, the spring one 432 is compressed and deformed by the convex ring 431, and at this time, the sliding rod 43 drives the push plate 433 to move outward; the inner side surface of the push plate 433 is connected with one end of the piston rod, so that the piston part 453 moves away from the ball 42, after the piston part 453 moves away from the sponge plug 454, the oil inlet hole 450 is opened, the lubricating oil in the oil storage cylinder 44 enters the inner cavity of the abutment column 45 through the oil inlet hole 450, gradually infiltrates the sponge plug 454, the sponge plug 454 transfers the lubricating oil, and the lubricating oil is overflowed through the center hole 4510, in the rolling process of the ball 42, the ball 42 contacts the sponge plug 454, so that the lubricating oil on the surface of the ball 42 is coated.After the lubricating oil is extruded, the ball 42 is lubricated, reducing the frictional resistance of the contact between the sliding seat 41 and the guide rail 21, and the lubricating oil can also play a role in cooling. After cooling, the temperature of the expansion column 452 decreases and gradually shrinks. At this time, the sliding rod 43 is no longer resisted by the expansion column 452, and the piston member 453 is reset under the reverse elastic force of the spring 1 432 and the spring 2 434. The piston moves to the sponge plug 454 side again, seals the oil inlet hole 450, and applies a certain resistance pressure to the sponge plug 454, so that the saturated lubricating oil of the sponge plug 454 is extruded from the center hole 4510 and the flow equalizing hole 4511, realizing uniform lubrication of the ball 42.
