[0002] The laser rangefinder is an instrument that uses a certain parameter of modulated laser to measure the distance to the target. In offshore wind power projects, piles need to be driven at sea, so the piles need to be located during construction. The position of the laser rangefinder is first obtained by GPS, and then the position of the pile is obtained by the rangefinder. However, the following problems exist in the distance measurement process:

[0003] 1. Complex environment during construction, such as protecting instrument safety, dust, strong sunlight, wind and rain, etc.;

[0004] 2. The working platform can provide a stable support for the laser rangefinder, reducing the jitter caused by handheld operation, thereby ensuring the stability of the laser beam and the accuracy of measurement;

[0030] Among them, a first axial hole 6 is opened at the center of the bottom of the lower component 2, and the first axial hole 6 contains a first rotating shaft. The first rotating shaft passes through and is arranged on the base 1. The first rotating shaft in the first axial hole 6 is used as the axis center for horizontal adjustment of the lower component 2, so that the lower component 2 can be horizontally adjusted based on this as a reference, thereby eliminating the horizontal deviation that exists during distance measurement.

[0031] Among them, four groups of first arc grooves 7 are opened at the bottom of the lower component 2, and the four groups of first arc grooves 7 are ring-shaped and surround the periphery of the first axial hole 6. A first stabilization hole 8 is opened on the base 1. The position and number of the first stabilization holes 8 correspond to the first arc grooves 7. Bolts are placed in the first stabilization holes 8. When the lower component 2 is adjusted horizontally, the bolts are used to limit it within the range of the first arc groove 7, so that the lower component 2 can be adjusted horizontally in the range of 0° to 30°. After adjusting the angle, the bolts can be tightened to fix it directly.

[0032] Among them, a second axial hole 9 is opened on the side of the upper component 3, and the second axial hole 9 contains a second rotating shaft. The second rotating shaft passes through and is arranged on the lower component 2. The intersection surfaces of the lower component 2 and the upper component 3 are both arc-shaped side plates, and the second axial hole 9 is located at the center of the arc-shaped side plate of the upper component 3. The second rotating shaft in the second axial hole 9 is used as the axis of the vertical adjustment of the upper component 3, so that the upper component 3 can be vertically adjusted based on this, eliminating the vertical deviation that exists during distance measurement.

[0033] Among them, a second arc groove 10 is opened on the arc-shaped side plate of the upper component 3, and the arc center of the second arc groove 10 coincides with the position of the second axial hole 9. Three groups of second stabilization holes 11 are opened on the side of the lower component 2, and the three groups of second stabilization holes 11 are all located in the range covered by the inner wall of the second arc groove 10. The bolts installed in the second stabilization holes 11 are used to limit the moving range of the second arc groove 10, and the laser azimuth of the laser rangefinder can be adjusted in the vertical direction so that the vertical range can be adjusted within 0° to 45°. After adjusting the angle, the bolts are tightened. At the same time, the three groups of second stabilization holes 11 can increase the contact points between the upper component 3 and the lower component 2, thereby improving the supporting capacity of the lower component 2.

[0034] Among them, the laser ranging mechanism 4 includes a ranging box 41, the interior of the ranging box 41 accommodates the laser rangefinder body 12, a card slot 44 is opened on the front of the ranging box 41, the light shield 5 is connected to the inside of the card slot 44, and a ranging box cover 43 is installed on the top of the ranging box 41. A stabilizer 42 is integrally provided at the outer edge of the ranging box 41. The ranging box 41 is installed on the upper component 3 through the stabilizer 42 by bolts. By setting the card slot 44, the light shield 5 and the laser ranging mechanism 4 are detachably arranged.

The laser window 45 is located at the center line of the light shield 5. The interior of the ranging box 41 is reserved with a cavity for accommodating the data interface of the laser rangefinder body 12. By setting the laser window 45, the laser transmitting and receiving positions of the installed laser rangefinder body 12 are both in fixed positions, which facilitates the externally installed light shield 5 to be directly aligned with the laser shooting position. At the same time, based on the ranging of the hull, the reserved cavity can accommodate the wires plugged into the laser rangefinder body 12 to a certain extent, so as to prevent the wires from being exposed to the outside and being contaminated by water vapor.

[0036] Among them, the light-shielding cover 5 includes a light-shielding tube 52, which is clamped on the end of the laser ranging mechanism 4, and a securing plate 51 is welded on the side of the light-shielding tube 52 away from the laser ranging mechanism 4, and the securing plate 51 is perpendicular to the light-shielding tube 52. The light-shielding cover 5 is used to shield the short-range laser path of the laser ranging mechanism 4 to prevent external strong light from affecting the laser receiving mechanism of the laser ranging mechanism 4 during ranging, thereby reducing the impact of the environment on the ranging ability.

[0037] Working principle: when using the laser rangefinder work platform for distance measurement, first determine whether to use the light shield 5 according to the environmental conditions, then connect the wire to the inside of the laser distance measuring mechanism 4, and according to the landing point of the laser emitted by the laser distance measuring mechanism 4, rotate the lower component 2 with the first axial hole 6 as the axis to adjust the horizontal direction of the laser distance measuring mechanism 4. After the horizontal direction adjustment is completed, fix the lower component 2 with the bolt set in the first stabilizing hole 8, and then adjust the inclination of the upper component 3 with the second axial hole 9 as the axis, and then adjust the vertical direction of the landing point of the laser distance measuring mechanism 4. After the adjustment is completed, fix the lower component 2 and the upper component 3 with the bolt in the second stabilizing hole 11.
