[0020] In addition, it should be noted that in the description of the utility model, unless otherwise specified and limited, the terms "mounting", "connection", "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the connection between two elements. For those skilled in the art, the specific meaning of the above terms in the utility model can be understood according to the specific situation.
[0021] According to an example of the utility model, referring to Figure 1 The utility model discloses a tidal current power generation pile body guide rail size and position tolerance measuring tool which is composed of a main frame 1, a guide groove support 2, a roller assembly 3, a laser range finder 4 and a limiting screw block 5. The main frame 1 is composed of a horizontal rod 11 and left and right cantilevers. The guide groove support 2 is connected to the bottom end of the cantilever. The three vertical inner wall surfaces of the guide groove support 2 are provided with the roller assembly 3. One or more inner wall surfaces of the guide groove support 2 are provided with the limiting screw block 5 and the laser range finder 4. The laser range finder 4 arranged up and down can scan and measure the specific size of the guide rail. The guide groove support 2 can flexibly simulate different guide groove widths through the limiting screw block 5, so as to check whether the matching size of the existing guide groove guide rail can meet the requirements.
[0022] Referring to Figure 2 The roller assembly 3 is composed of an adjusting screw 31, an adjusting nut 32, a roller support 33 and a roller 34. The roller 34 can be detachably arranged on the roller support 33. The roller support 33 is detachably installed on the guide groove support 2 through the adjusting screw 31 and the adjusting nut 32. After the roller assembly 3 is integrated, the guide groove support 2 is integrally installed on the guide rail to be measured. During the movement of the roller 34 along the length direction of the guide rail, the laser range finder 4 and the limiting screw block 5 or the plug gauge on the tool can measure the size and position tolerance.
[0023] Referring to Figure 3As shown, the crossbar 11 is a split structure or a telescopic structure composed of multiple bar segments. By varying its length, it can accommodate the measurement requirements of piles with different diameters. Depending on the measurement requirements involving multiple guide grooves and guide rails, two or more sets of crossbars 11 can be welded or bolted together to form a combined measuring fixture. If there are measurement requirements involving multiple guide grooves and guide rails, two or more sets of fixtures can be welded or bolted together to form a combined measuring fixture.
[0024] The roller assembly 3 uses adjusting screws 31 and adjusting nuts 32 to adjust the installation position of the roller support 33 in the guide rail support 2. Its flexible adjustment method can accommodate the measurement requirements of guide rails of different sizes. The limiting screw block 5 of the guide rail support 2 can flexibly simulate different guide rail widths, thereby verifying whether the existing guide rail matching dimensions meet the requirements. If the dimensions of the matching guide rail are known, it is only necessary to verify whether the existing guide rail dimensions can move smoothly. This can be done by adjusting the dimensions of the roller 34 and the limiting screw block 5, and then rolling the entire fixture on the guide rail. If the fixture can smoothly pass through the entire guide rail, it indicates that the two are matched. If there are any jams, they can be modified accordingly, saving a significant amount of measurement time and quickly locating problem points for rapid adjustment.
[0025] See the structural schematic diagram of the pile body, guide rail, and guide groove. Figure 4 , Figure 5 and Figure 6 As shown, the guide rails are welded to the pile body and secured inside the guide groove. First, after the pile body is processed, the welding positions of the guide rails are initially determined by positioning and marking on the pile body. Then, a pair of guide rails are spot-welded parallel and symmetrically onto the pile body. Due to the large size and weight of the pile body, and the fact that the pile body itself is generally not perfectly circular or straight, it is difficult to find a definite positioning benchmark for the guide rails, which may cause deviations in the initial installation position of the guide rails. After the guide rails are spot-welded onto the pile body, the pile body is laid flat, and a level is used to ensure that the connecting plane of the two guide rails is as parallel to the ground as possible. At this point, the measuring fixture of this patent application can be installed according to the attached... Figure 1The measuring tool is installed on the guide rail, the measuring tool is located on the guide rail by adjusting the rollers, the measuring tool is adjusted to be parallel to the ground by the level, then the measuring personnel can stand on the pile column, push the measuring tool to roll along the guide rail, and monitor the levelness of the measuring tool, at this time, the levelness of the tool and the parallelism of the guide rail are related, if the measuring tool can keep horizontal all the time, the two guide rails are also parallel, if the measuring tool cannot keep horizontal, the position of the guide rail can be adjusted according to the direction of the inclination. In the rolling process, the distance between the inner surface of the guide groove and the guide rail can be checked by the laser range finder 4 or the feeler gauge, so that the size and the geometric tolerance of the guide rail are obtained, and the guide rail is adjusted according to the needs. After the guide rail is completely welded, the final size of the guide rail can be rechecked according to the above method, so as to avoid the deviation of the size and the position of the guide rail after welding deformation beyond the tolerance requirements, and to confirm that the guide rail can meet the factory acceptance.
[0026] If the guide rail is processed, the matched guide groove has been processed, the final size of the guide groove is known, at this time, if only the existing guide rail size needs to be checked whether it can meet the requirements, the size of the adjusting roller 34 and the size of the limiting screw block 5 can be adjusted to simulate the real guide groove, and then the whole tool is installed on the guide rail, if the tool can smoothly pass through all the guide rails, it is proved that the two are matched, if there are some places that are blocked, the corresponding modification can be made, a large amount of measurement time and rapid positioning problem points can be saved, so as to quickly adjust. According to different diameters of the pile body and different sizes of the guide groove, the tool can adjust the size of the cross bar 11 of the main frame 1, adjust the position of the adjusting roller 34, and adjust the limiting screw block 5, so as to adapt to different measurement requirements. See Figure 2 、 Figure 3 For the application of multiple guide grooves up and down, the tool can be spliced and combined to meet the corresponding needs, see Figure 6 .
[0027] The above examples only exemplarily illustrate the principle and effect of the tool, and part of the applied examples, for the ordinary skilled in the art, without departing from the creative concept of the tool, a number of modifications and improvements can be made, which belong to the protection scope of the tool.
