Description

Technical Field

[0001] The utility model relates to the technical field of manufacturing measurement equipment, in particular to a horizontal benchmark device and a measurement equipment. Background Art

[0002] According to the shipbuilding industry standards, when a ship undergoes the operation of shifting and sitting on a pier in a dry dock, all its technological processes and safety guarantee measures must strictly follow the relevant national standards. Specifically, ship shifting refers to the process in which, after a ship completes the outfitting of a specified length in a dry dock, the ship is made to float by draining water, and then it is moved to another position by using a traction trolley and a tugboat. Sitting on a pier means that, when the whole ship is drained of water and another ship in the dry dock floats, it is necessary to ensure that the ship can stably sit on the original dock pier or a specified new dock pier. In this process, the national standards clearly require the preparatory work before the half-ship floats, including that the hull structure must ensure the integrity below the waterline in the engine room area, and at least one complete cargo hold in the cargo hold area to meet the floating conditions; temporary water level gauges should be set at the first rib position at the front end and the rib position of the last bulkhead on both sides of the hull, the height of which is determined according to the floating draft requirements, and scales are marked at intervals of 20 meters; after using laser positioning technology to adjust the ship to the correct position, water is pumped out to ensure that the tolerances in the front, back, left and right directions during sitting on the pier do not exceed ±50 mm. In order to accurately monitor the longitudinal and transverse inclination values before, after and during the floating of the ship and sitting on the pier, the shipyard welded three auxiliary laser level benchmarks on each side of the hatch coaming of the cargo hold. Although this has improved the measurement accuracy, directly welding the benchmarks on the hull will damage the original paint, and subsequent removal requires repair welding and grinding, which not only increases the construction complexity but also poses a challenge to the protection of the hull paint.

[0026] In the related art, in order to accurately monitor the longitudinal and transverse inclination values of the floating ship and the sitting pier before, during, and after the process, the shipyard welded three auxiliary laser level measuring rods on each side of the hatch coaming of the cargo hold. Although this improved the measurement accuracy, directly welding the rods on the hull would damage the original paint, and subsequent removal would require repair welding and grinding, which not only increased the construction complexity but also posed a challenge to the protection of the hull paint.

[0027] To solve this problem, an embodiment of the present utility model provides a level measuring rod device. After the shipboard is clamped into the clamping groove of the base 100, the base 100 and the rod body 200 can be fixed on the shipboard through the locking member 140. And a flexible member is provided at the lower end of the locking member 140, so that the paint on the surface of the shipboard will not be damaged during fixation, avoiding the phenomenon that the hull paint is damaged due to welding the rod on the shipboard. The following will further illustrate the specific structure and function of the level measuring rod device provided by the embodiment of the present utility model in combination with the text and the drawings.

[0028] Refer to Figures 1 to 3 According to the level measuring rod device provided by some embodiments of the present utility model, it includes: a base 100 and a rod body 200. The base 100 includes a horizontal plate 110, a vertical plate 120, a clamping plate 130, and a locking member 140. The horizontal plate 110 is arranged horizontally, the vertical plate 120 is connected to one side of the horizontal plate 110 and extends vertically downward, the clamping plate 130 is connected to the vertical plate 120 and is parallel to the horizontal plate 110, and a clamping groove for clamping the shipboard is defined between the clamping plate 130 and the horizontal plate 110; the locking member 140 is arranged on the horizontal plate 110 from top to bottom, a flexible member (not shown in the figure) is provided at the lower end of the locking member 140 and extends into the clamping groove, and the flexible member can press and clamp the shipboard clamped into the clamping groove. The rod body 200 includes a first plate body 210 and a second plate body 220. The first plate body 210 and the second plate body 220 are both connected to the upper end surface of the horizontal plate 110 and are arranged vertically, and the first plate body 210 and the second plate body 220 are perpendicular to each other.

[0029] According to the horizontal benchmark device provided by some embodiments of the present utility model, when it is necessary to set up the horizontal benchmark device on the hull, move the base 100 to the position where the horizontal benchmark device needs to be set up. Then, make the horizontally arranged shipboard be caught in the clamping groove defined between the clamping plate 130 and the cross plate 110. Then, adjust the locking member 140 downward so that the flexible part at the lower end of the locking member 140 presses against and catches the upper end of the shipboard caught in the clamping groove. The pre-tightening force among the locking member 140, the shipboard, and the clamping plate 130 can make the base 100 stably clamped on the shipboard. At this time, the benchmark body 200 stands on the base 100, facilitating subsequent measurement. When the measurement is completed, adjust the locking member 140 upward. After the lower end of the adjusting member is separated from the shipboard, the base 100 can be removed. The operations of both installation and disassembly are simple and convenient. For the horizontal benchmark device provided by the embodiments of the present utility model, after the shipboard is caught in the clamping groove of the base 100, the base 100 and the benchmark body 200 can be fixed on the shipboard through the locking member 140. Moreover, a flexible member is provided at the lower end of the locking member 140, and the paint on the surface of the shipboard will not be damaged during fixation, avoiding the phenomenon that the hull paint is damaged due to welding the benchmark on the shipboard.

[0030] It can be understood that the flexible member can be a rubber soft pad, a silica gel soft pad, etc. The first plate body 210 and the second plate body 220 of the rod body are perpendicularly arranged, which is beneficial to ensuring the overall structural strength of the benchmark body 200, making the body not easy to bend, and avoiding the phenomenon that the benchmark body 200 is bent due to factors such as collision during use, resulting in a large measurement error.

[0031] Refer to Figure 1 and Figure 3 According to the horizontal benchmark device provided by some embodiments of the present utility model, locking members 140 are provided at both horizontal ends of the cross plate 110. The cooperation of the two locking members 140 can better lock the base 100 and ensure the stability of the connection between the base 100 and the shipboard.

[0032] Refer to Figure 1 and Figure 2 According to the horizontal benchmark device provided by some embodiments of the present utility model, the locking member 140 includes a screw rod. A threaded hole is provided on the upper end surface of the cross plate 110. The screw rod penetrates and is threadedly connected to the threaded hole. By rotating the screw rod, the locking member 140 can be raised or lowered, thereby loosening or pressing the shipboard caught in the clamping groove. The operation is simple and convenient.

[0033] Refer to Figure 1 and Figure 2 According to the horizontal benchmark device provided by some embodiments of the present utility model, a regular hexagonal clamping portion is provided at the top of the screw rod. Through the clamping portion, the screw rod can be driven to rotate, facilitating the operator to manually or use tools to rotate the screw rod.

[0034] Refer to Figure 1 andFigure 2 For the horizontal benchmark device provided by some embodiments of the present utility model, the horizontal plate 110 and the vertical plate 120 are of an integrally formed structure, which is beneficial to improving the structural strength between the horizontal plate 110 and the vertical plate 120; the clamping plate 130 is fixed to the vertical plate 120 by welding, and the connection manner between the clamping plate 130 and the vertical plate 120 is stable and reliable.

[0035] Refer to Figure 2 and Figure 3 For the horizontal benchmark device provided by some embodiments of the present utility model, the first plate body 210 and the second plate body 220 are of an integrally formed structure, which is beneficial to the structural strength between the first plate body 210 and the second plate body 220; and the lower ends of the first plate body 210 and the second plate body 220 are fixed to the upper end surface of the horizontal plate 110 by welding, and the fixing manner of the first plate body 210, the second plate body 220 and the horizontal plate 110 is stable and reliable.

[0036] The measuring device provided by some embodiments of the present utility model includes two laser leveling devices and the horizontal benchmark device as provided by the embodiments of the present utility model. The two laser leveling devices and the horizontal benchmark device can measure the hull more conveniently and efficiently.

[0037] It can be understood that before the ship enters the dock for water filling operation, the primary task is to ensure that the benchmark devices at all positions are firmly installed and immovable. Subsequently, two laser leveling devices are respectively arranged on both sides of the dock, and laser level points are accurately marked on the benchmark body 200, and center punches are used for marking to ensure clarity and distinguishability. The six center punch points on these six benchmark bodies 200 must be strictly controlled on the same horizontal plane to ensure the accuracy of measurement. After the water is filled in the dock, use these two laser leveling devices to measure and record the height differences between the six center punch points on the benchmark body 200 on the ship. This height difference directly reflects the longitudinal inclination and transverse inclination conditions of the hull. According to the specific process requirements of the shipyard, the horizontal difference of the hull is accurately adjusted by adjusting the ballast water volume or hanging ballast iron to meet the various process standards before moving the ship to the left saddle. In addition, after the ship is shifted and stabilized on the saddle, it is also necessary to recheck the six-point center punch level value set by the shipyard to ensure that the state of the hull after sitting on the saddle fully meets the process requirements.

[0038] The above has described the embodiments of the present utility model in detail with reference to the drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present utility model.
