Description

Technical Field

[0001] This invention relates to the field of shipbuilding technology, and more specifically to a horizontal adjustment device for a theodolite. Background Technology

[0002] In existing technologies for ship shaft and rudder propulsion systems, the precise positioning of the shaft and rudder centerline generally uses the plumb line method. This involves using a collimating telescope for precise shaft centerline positioning and a plumb line for precise rudder line positioning. During plumb line positioning, a reference point is set at both the bow and stern of the shaft. A total station is used to adjust the X, Y, and Z coordinates of these reference points to align with the shaft centerline. The collimating telescope is then adjusted so that the center point of the crosshairs emitted by the telescope coincides with the reference points. The light emitted by the collimating telescope at this point represents the shaft centerline.

[0003] After the axis is positioned, since the collimating telescope cannot be adjusted vertically, the rudder line is positioned using a plumb line. Project the axis centerline and the 0# rib line onto the ground, intersecting at point E. Install a hanging point at the top of the rudder system and hang a steel wire. Attach a plumb line to the end of the steel wire near the ground. Adjust the top hanging point so that the tip of the plumb line is aligned with point E on the ground. Once adjusted, this line is the rudder system centerline.

[0004] The aforementioned wire-guided illumination method for rudder line positioning can easily lead to inaccurate rudder system centerline positioning during ship inspections. Specifically, there are four main reasons for this: First, the bottom cone angle of the plumb bob is relatively blunt, making it difficult to accurately align with point E on the ground; second, the plumb bob is easily affected by wind, and even a slight breeze can cause it to swing, increasing the difficulty of on-site positioning; third, the steel wire may be bent or twisted, and the light weight of the plumb bob may not completely straighten the wire, increasing the positioning error of the rudder line; fourth, the standard requirement for the intersection of the shafting centerline and the rudder system centerline is less than or equal to 4mm, and the intersection needs to be checked by pulling a steel wire.

[0005] To solve the above problems and achieve precise positioning of the rudder line, existing technologies typically use illumination methods. Both the shaft centerline and the rudder centerline are illuminated using instruments, specifically illumination theodolites. Before illumination with the theodolite, the X, Y, and Z coordinates of the bow reference point are adjusted to align with the shaft centerline using a total station. The shaft centerline and the 0# rib line are then projected onto the ground, intersecting at point E. During illumination, the theodolite is placed above point E and leveled. The laser is activated, and the focus is adjusted. By adjusting the theodolite's elevation, the laser point passes the forward reference point. The theodolite is then rotated downwards by 90° and locked. The position of the theodolite is adjusted forward, backward, left, and right until the laser point is aligned with point E on the ground. This adjustment is repeated until the theodolite is level, the laser passes the forward reference point, and the theodolite is rotated downwards by 90° so that the laser point is simultaneously aligned with point E on the ground. After the theodolite is fully adjusted, the line where the horizontal laser emitted by the theodolite is located is the shaft centerline. After rotating 90° downwards / upwards, the line where the laser is located becomes the center line of the rudder system.

[0006] A light-based theodolite can accurately locate the center lines of the shaft system and rudder system, solving the problem of inaccurate rudder system center line positioning using string lines. However, adjusting the light-based theodolite in the horizontal direction is difficult and has low accuracy. Summary of the Invention

The theodolite 5 is detachably and fixedly connected to the second sliding plate 4. The base 1, the first sliding plate 3, and the second sliding plate 4 are all provided with through holes for the laser of the theodolite 5 to pass through.

[0042] When it is necessary to move the position of the illumination theodolite 5, the position of the second sliding plate 4 is adjusted to move the illumination theodolite 5 in the X direction, and the position of the first sliding plate 3 is adjusted to move the illumination theodolite 5 in the Y direction, ultimately achieving the purpose of adjusting the horizontal position of the illumination theodolite 5.

[0043] The lower edge of the base is detachably fixed to the ship plate by fasteners, such as bolts or pins, which are easy to disassemble. In other embodiments of this application, the base and the ship plate can also be magnetically fixed together by a magnetic base device.

[0044] In specific embodiments of this application, such as Figures 4 to 5 As shown, a platform is fixedly installed on the upper part of the base 1. The platform 21 can be welded and fixedly connected to the base 1. The two sides of the platform 21 in the X direction are provided with first protrusions 211, and the two sides of the platform 21 in the Y direction are provided with first protruding edges 212. The height of the first protrusions 211 is higher than the height of the first protruding edges 212. The first slide plate 3 is slidably disposed in the space enclosed by the first protrusions 211 and the first protruding edges 212 in the Y direction. Specifically, the first slide plate 3 slides along the first protruding edge 212. The first positioning member is a first positioning bolt 10 that can be detachably installed on the first protrusions 211. When the first slide plate 3 moves to a suitable position in the Y direction, the first positioning bolt 10 abuts against the first slide plate 3 to fix the first slide plate 3.

[0045] In a specific embodiment of this application, the base 1 specifically includes a vertically extending vertical rod and a bottom plate fixedly connected to the vertical rod. The bottom plate is connected to the ship plate, and ribs are also inclinedly arranged between the vertical rod and the bottom plate to support the vertical rod and increase its stability. Furthermore, in this specific implementation, the bottom plate is specifically arranged as a square plate, with the connection between the bottom plate and the ship plate located at a corner of the square plate. An arc-shaped concave notch is reserved on the bottom plate between the two corners to reduce the weight of the base 1 while meeting its strength requirements.

[0046] Meanwhile, a first cover plate 15 is detachably mounted on the first protruding edge 212, and both the first cover plate 15 and the first protruding edge 212 are threadedly connected. Specifically, the first cover plate 15 has a first protrusion protruding from the first protruding edge 212 near the edge of the first slide plate, that is, the first protrusion is spaced apart from the upper part of the platform 21, and the first protruding edge 212 and the first protrusion form a first guide groove for guiding the movement of the first slide plate 3. The first guide groove allows the first slide plate 3 to be guided and moved, thereby improving the movement accuracy of the first slide plate 3 in the Y direction.

[0047] like Figures 6 to 7 As shown, the first slide plate 3 has a second protruding edge 31 on both sides of its X-direction and a second boss 32 on both sides of its Y-direction. The height of the second boss 32 is higher than the height of the second protruding edge 31. The second slide plate 4 is slidably disposed in the space enclosed by the second boss 32 and the second protruding edge 31 along the X-direction. Specifically, the second slide plate 4 slides along the second protruding edge 31. The third positioning member is a second positioning bolt 11 that can be detachably installed on the second boss 32. The second positioning bolt 11 abuts against the second slide plate 4 to position the second slide plate 4 when it moves to a suitable position.

[0048] Meanwhile, a second cover plate is provided on the second protruding edge 31, and the second cover plate and the second protruding edge 31 are bolted together; the edge of the second cover plate near the second slide plate 4 has a second protrusion that protrudes from the second protruding edge, that is, the first protrusion is spaced apart from the upper part of the first slide plate 3; the second protruding edge and the second protrusion form a second guide groove for guiding the movement of the second slide plate 4. The second boss 32 is used to bear the tightening torque of the adjusting screw of the intermediate slide plate; the second slide plate 4 is designed with a through hole in the middle for the laser to pass through. The second slide plate 4 can move in the X-axis direction, driving the illumination theodolite 5 to perform adjustment and positioning in the X-axis direction.

[0049] In specific embodiments of this application, such as Figure 1 , Figures 9 to 10 As shown, third protrusions 41 are provided on both sides of the second slide plate 4 in the X direction. Multiple spacer screws 12 are vertically fixed on the second slide plate 4, and a fixing plate 13 is detachably connected to the upper part of each spacer screw 12. The theodolite 5 is detachably fixed to the fixing plate 13. Specifically, the spacer screws 12 are arranged vertically, with their bottoms threaded to the second slide plate 4 and their upper parts threaded to the fixing plate 13. The spacer screws 12 can rotate around the fixing plate 13 to adjust its height. Light holes are also provided at the four corners of the fixing plate 13, and the spacer screws 12 are installed within these light holes.

[0050] Furthermore, a recessed groove 221 communicating with the mounting hole is provided in the middle of the fixing plate 13. The depth of the recessed groove 221 is greater than the thickness of the fixing nut, so as not to affect the tight connection between the light-illuminating theodolite 5 and the fixing plate 13. The fixing bolt is designed with a through hole in the middle for the laser to pass through.

[0051] Each of the fixed-distance screws 12 is provided with multiple positioning grooves 121 that match the wrench, making it easy to tighten or loosen with tools such as wrenches.

[0052] The method of using the positioning and adjustment device of the illumination theodolite 5 of the present invention is as follows: Assemble the above components according to the assembly diagram of the base 1 from bottom to top, fix the illumination theodolite 5 on the fixing plate 13, and fix the base 1 on the steel platform 21.

[0053] The method for adjusting the theodolite 5 in the forward / backward direction (X-axis) is as follows: An adjusting screw is installed at the second protrusion 32 located between the two ends of the first slide plate 3. A sliding mechanism is formed by the cooperation of the second protruding edge 31 of the first slide plate 3, the cover plate, and the two ends of the first slide plate 3 not at the second protrusion 32, allowing the second slide plate 4 to slide. Tightening / loosening the adjusting screw allows the theodolite to move along the X-axis.

[0054] Adjustment method for the theodolite 5 in the left-right direction (Y-axis): An adjustment screw is installed at the first protrusion 211 in the middle of both ends of the lifting platform 2. The sliding mechanism formed by the cooperation of the first protrusion 212 of the lifting platform 2, the cover plate, and the two sides of the second protrusion 32 of the first slide plate 3 allows the first slide plate 3 to slide. Tightening / loosening the adjustment screw allows the theodolite to move along the Y-axis.
