Problems solved by technology

[0002] Shafting equipment such as the main engine and gearbox need to be centered and positioned before they are placed. In the current ship construction process, most of the shafting equipment such as the main engine and gearbox are centered and positioned by drawing steel wires as the reference, using long tapes, etc. The measurement accuracy is not high. The measurement method is carried out, and the error of measurement data accumulation is relatively large. Often, the final installation position of the shafting equipment such as the main engine and the gearbox exceeds the normal size range relative to the initial hoisting position (theoretical positioning position), and has to be carried out beyond the normal size range. The position correction of the size range produces uncontrollable construction risks

Embodiment 1

[0039] The embodiment of the present invention provides a positioning and measuring tool for the base of marine equipment, the structure of which is as follows figure 1 and figure 2 As shown, it includes a bracket 1, a light target 2 and a horizontal reference plane 3. The bracket 1 is installed on the equipment base 8 to be tested through more than three height adjustment bolts 4, and the height of the tooling relative to the equipment base can be adjusted through the height adjustment bolts. The height position and horizontal state make the positioning and measuring tooling of the ship's equipment base in a horizontal state, the center of the light target is coaxial with the laser beam passing through the reference point of the shaft system on the ship, and the axial positioning reference plane and the foot of the equipment base The spacing dimension L2 between the centers of the first mounting bolt holes at the rear meets the requirements. The quantity of height adjustmen...

Embodiment 2

[0045] Based on the same inventive concept, the present invention also correspondingly provides a positioning measurement method, which is implemented based on the positioning measurement tool for the base of the marine equipment in the first embodiment. Before implementation, it is first necessary to draw a center line at the center of the mounting bolt holes on the equipment base 8 according to the design theory data. see image 3 and Figure 4 , the positioning measurement method specifically includes the following steps:

[0046] 1. Positioning of the tooling: the positioning and measuring tooling of the ship equipment base is placed on the equipment base 8 to be tested; specifically, in this embodiment, the tooling is hoisted onto the equipment base 8 through four lifting lugs 7 .

[0047] 2. Tooling adjustment: adjust the tooling to the design theoretical position of the main engine, gearbox and other shafting equipment.

[0048] 2-1. Adjust the positioning and measur...

Abstract

The invention discloses a ship equipment base positioning and measuring tool and a positioning and measuring method. The tool comprises a support, a light target and a horizontal reference surface. The support is installed on an equipment base to be detected through more than three height adjusting bolts, the support is provided with an axial positioning reference surface and a height direction measurement reference surface, and the support is a symmetrical structure. The axial symmetric surface of the support is a left-right direction positioning reference surface, and the light target is mounted on the support and is coaxial with the axis reference of the ship; and the horizontal reference surface is arranged on the support and located on a horizontal installation reference surface of shafting equipment of the ship. The ship equipment base positioning and measuring tool integrates a shafting axis reference, a horizontal mounting reference surface and an axial positioning reference of shafting equipment such as a main engine, a gear box and the like, replaces a traditional measuring mode of purely taking a measuring reference of pulling a steel wire and a measuring tape as a measuring tool, can be matched with irradiation centering and positioning, and realizes reliable, convenient and high-precision positioning and measuring.
