Description

Technical Field

[0001] The invention relates to the technical field of shipbuilding, in particular to a position-adjustable rudder system illumination laser theodolite base. Background Art

[0002] With the acceleration of shipbuilding, the dock cycle is becoming more and more tight. In order to balance the load of construction operations in the dock, the shipyard began to pre-boring the ground section, pre-boring the stern shaft margin in advance, reducing the stern shaft margin from the original 10mm on one side to 3mm or even less, and then lighting work was carried out when the dock was loaded to meet the lighting conditions, so that the amount of boring operations in the dock was reduced. Due to the reduction of the stern shaft margin, the refinement of the shaft rudder system lighting and centering is required to be higher, otherwise it will be impossible to perform margin processing or the relevant measurement data will be out of tolerance.

[0003] The common practice is to place a laser theodolite installation platform at the intersection of the rear of the stern hole and the bottom of the rudder hole, install the laser theodolite and its base on the platform, irradiate the laser on the stern hole and the rudder hole, and adjust the laser theodolite base by checking the deviation between the laser point and the center point of the stern hole, rudder hole and main engine slot benchmark. However, it is difficult to adjust to the required position point during the adjustment process in the front, back, left, right, up and down directions. The reasons are as follows:

[0004] During each adjustment process, the front and rear and left and right directions are adjusted by drawing lines on the platform, irradiating the laser point on the platform, drawing lines with the front and rear laser points, finding the center point of the platform where the laser theodolite is located through the eyepiece on the laser theodolite, using a tape measure to offset the front and rear and left and right, drawing a new center point, moving the laser theodolite to coincide with the new center point by observing the eyepiece, and using a tape measure tool to raise and lower the laser theodolite base next to the laser theodolite in height direction. These operations are prone to deviations, and there is a situation where the offset distance is insufficient or too large, and then repeatedly confirming the deviation between the laser point and the center point of the stern shaft hole, rudder hole and main engine slot benchmark, and repeatedly adjusting the laser theodolite base. It consumes a lot of manpower and time, and the on-site work and operation are difficult.

[0005] Even after the laser theodolite is moved to the desired location, it is easy for it to be hit by objects or bumped by people during the process of surveying and marking the shaft hole and rudder hole inspection and measuring the related data, causing the laser theodolite to shift, which poses a very high risk of having to re-illuminate the operation.

[0006] Therefore, a position-adjustable axial rudder system illumination laser theodolite base is needed to solve the above problems. Summary of the invention

[0007] The object of the present invention is to provide a position-adjustable rudder system illumination laser theodolite base, which is convenient for adjusting the position of the laser theodolite and can eliminate the risk of re-illumination operation.

[0037] In the process of ship construction, in order to facilitate the adjustment of the position of the laser theodolite and eliminate the risk of re-lighting operations, such as Figure 1-Figure 4 As shown, the present invention provides a position-adjustable axial rudder system illumination laser theodolite base. The position-adjustable axial rudder system illumination laser theodolite base comprises a mounting platform 1, a fixed bottom plate 2, a sliding base 3 and a lifting support frame 4.

[0038] The fixed base plate 2 is arranged on the erection platform 1 through the connection assembly 5, and the position of the fixed base plate 2 on the erection platform 1 can be adjusted. The sliding base 3 is fixedly arranged on the side of the fixed base plate 2 away from the erection platform 1, and the sliding base 3 is provided with a first scale 321 arranged along a first direction and a second scale 3311 arranged along a second direction, and the first direction is perpendicular to the second direction. The lifting support frame 4 is arranged on the side of the sliding base 3 away from the fixed base plate 2, and the position of the lifting support frame 4 on the sliding base 3 can be adjusted. Figure 2-Figure 4 As shown, the first direction is the X direction, and the second direction is the Y direction.

[0039] When adjusting the position of the laser theodolite, the position of the fixed base plate 2 relative to the erection platform 1 is adjusted roughly, and then the position of the fixed base plate 2 on the erection platform 1 is locked by the connection component 5, and the position of the lifting support frame 4 is finely adjusted by the first scale 321 and the second scale 3311. In the above manner, it is convenient to adjust the position of the laser theodolite. Moreover, by locking the position of the fixed base plate 2 on the erection platform 1 by the connection component 5, the position of the laser theodolite after installation can be limited to avoid displacement and eliminate the risk of re-illumination operation.

[0040] In some embodiments, a first strip hole 11 is provided on the erection platform 1 along the first direction, and the connection component 5 is inserted into the fixed bottom plate 2 and the first strip hole 11. By providing the first strip hole 11 extending along the first direction, the position of the fixed bottom plate 2 can be adjusted along the first direction, thereby roughly adjusting the position of the lifting support frame 4 along the first direction, and then the relative position of the fixed bottom plate 2 and the erection platform 1 is locked by using the connection component 5.

[0041] In some embodiments, a second strip hole 21 extending along the second direction is provided on the fixed base plate 2, and the connecting component 5 is inserted into the first strip hole 11 and the second strip hole 21. By providing the second strip hole 21 extending along the second direction, the position of the fixed base plate 2 can be adjusted along the second direction, so as to roughly adjust the position of the lifting support frame 4 along the second direction, and then the relative position of the fixed base plate 2 and the erection platform 1 is locked by the connecting component 5. In this way, the relative position between the fixed base plate 2 and the erection platform 1 can be effectively and quickly adjusted.

[0042] In some embodiments, the connection assembly 5 includes a bolt 51 and a nut 52, and the bolt 51 passes through the second strip hole 21 and the first strip hole 11 and is connected to the nut 52. Through the cooperation between the bolt 51 and the nut 52, when it is necessary to adjust the relative position between the fixed base plate 2 and the erection platform 1, it is only necessary to loosen the nut 52, and then move and adjust the relative position between the fixed base plate 2 and the erection platform 1. After the adjustment is completed, the relative position between the fixed base plate 2 and the erection platform 1 can be locked by screwing the locking nut 52.

[0043] In some embodiments, the sliding base 3 includes a sliding base plate 32 and a slider assembly 33. The sliding base plate 32 is connected to the fixed base plate 2 through a plurality of fixed columns 31 arranged at intervals. The slider assembly 33 is slidably arranged on the side of the sliding base plate 32 away from the fixed base plate 2. The slider assembly 33 can slide on the sliding base plate 32 along the first direction and the second direction. The lifting support frame 4 is arranged on the slider assembly 33. The sliding base plate 32 and the fixed base plate 2 are arranged at intervals by the plurality of fixed columns 31, so as to form a space for installing the bolts 51, which is convenient for installing the bolts 51. By arranging the slider assembly 33 on the sliding base plate 32, the sliding base plate 32 limits the range of motion of the sliding assembly. By adjusting the position of the sliding assembly on the sliding base plate 32, the position of the lifting support frame 4 can be finely adjusted. A first scale 321 is arranged on the sliding base plate 32, and a second scale 3311 is arranged on the first slider 331. During the adjustment process, the first scale 321 and the second scale 3311 can be used for reference, so as to ensure fine adjustment.

[0044] In some embodiments, the slider assembly 33 includes a first slider 331 and a second slider 332, the first slider 331 is slidably disposed on the sliding base plate 32, and the first slider 331 can slide in a first direction, the second slider 332 is slidably disposed on the first slider 331, and the second slider 332 can slide in a second direction, and the lifting support frame 4 is disposed on the second slider 332. Through the above arrangement, the lifting support frame 4 can be adjusted to any position of the sliding base plate 32, so as to facilitate the adjustment of the position of the laser theodolite at the construction site.

[0045] In some embodiments, the sliding base 3 further includes a first limiter 34 and a second limiter, wherein the first limiter 34 is disposed between the sliding base plate 32 and the first slider 331, and is used to lock the relative position of the first slider 331 and the sliding base plate 32, and the second limiter is disposed between the first slider 331 and the second slider 332, and is used to lock the relative position of the first slider 331 and the second slider 332. In this embodiment, the first limiter 34 and the second limiter are both limit screws. By adjusting the first limiter 34 on the first slider 331 to abut against the sliding base plate 32, the position of the first slider 331 can be limited. By adjusting the second limiter on the second slider 332 to abut against the first slider 331, the position of the second slider 332 can be limited. In the above manner, after completing the position adjustment, the position of the laser theodolite can be locked so that it remains unchanged.

[0046] In some embodiments, the lifting support frame 4 includes a telescopic assembly and a fixed frame 44. The fixed end of the telescopic assembly is fixedly arranged on the second slider 332, and the movable end of the telescopic assembly is connected to the fixed frame 44. The height of the fixed frame 44 can be adjusted by the telescopic assembly, so as to flexibly meet the use of the construction site.

Specifically, the third stopper 43 is a stopper screw, which passes through the fixed sleeve 41 and can abut against the movable rod 42, thereby locking the position of the movable rod 42. By adjusting the extension length of the movable rod 42 relative to the fixed sleeve 41, the height of the telescopic assembly can be adjusted, thereby adjusting the position of the fixed frame 44.

[0048] In some embodiments, a third scale is provided on the movable rod 42 along the extension direction of the movable rod 42. By providing the third scale, guidance can be provided when adjusting the extension length of the movable rod 42 relative to the fixed sleeve 41, thereby quickly adjusting the height of the laser theodolite.
