[0002] An alignment instrument is a device used to perform alignment operations, mainly for detecting the relative position accuracy of connected devices, such as detecting whether the positions between device components are within the design tolerances. Alignment generally includes shaft alignment, hole alignment, geometric alignment, etc.
[0003] Bracket products for alignment instruments usually need to use a steel tape measure to measure distances to ensure the installation position of the alignment instrument. Only when the alignment instrument is installed accurately can accurate alignment operations be achieved. The alignment operation is a process of adjusting the relative positions of the devices at both ends of the shaft to within a specified range. However, the steel tape measure is inconvenient to use during the measurement process and has relatively large errors, affecting the accuracy and efficiency of the alignment operation.

The following combines Figures 1 to 8 , to make a detailed description of the centering instrument and the fixture for the laser measuring device of the centering instrument.
[0043] In one of the embodiments, a fixture 100 for a laser measuring device of a centering instrument is as Figure 1 shown, which includes a fixed fixture 110, a support frame 120, an adjustment mechanism 130 and a locking mechanism 140; combined with Figure 2As an example, the fixing fixture 110 is used to cooperate with the support frame 120 to fix the handheld laser rangefinder 200; the adjustment mechanism 130 is used to install the measuring rod 300 of the centering instrument, including installing the measuring rod 300 on the adjustment mechanism 130, or installing the adjustment mechanism 130 on the measuring rod 300; exemplarily, the locking mechanism 140 is used to lock the adjustment mechanism 130, so that the relative relationship between the laser measuring device fixture 100 and the measuring rod 300 remains fixed in the locked state; or in the non-locked state, In the tightened state, the laser measuring device fixture 100 can rotate circumferentially or move axially along the extension direction 310 of the measuring rod 300 relative to the measuring rod 300 through the adjustment mechanism 130, that is, the adjustment mechanism 130 can rotate or translate relative to the measuring rod 300, so that the positional relationship between the laser measuring device fixture 100 and the measuring rod 300 can be adjusted, and then the positional relationship between the handheld laser rangefinder 200 and the measuring rod 300 can be adjusted to ensure the measurement effect and measurement accuracy of the handheld laser rangefinder 200.
[0044] In each embodiment, Figure 1 and Figure 2 As shown, the adjustment mechanism 130 is provided with a clamping position 170, which is used for the adjustment mechanism 130 to be clamped on the measuring rod 300 of the centering instrument, and the measuring rod 300 is passed through the clamping position 170; the locking mechanism 140 is installed on the adjustment mechanism 130, and is used to lock the adjustment mechanism 130 on the measuring rod 300. In one embodiment, the adjustment mechanism 130 is clamped on the measuring rod 300 in a sleeve manner, that is, the measuring rod 300 passes through the adjustment mechanism 130, the adjustment mechanism 130 is sleeved on the measuring rod 300, and the adjustment mechanism 130 is clamped on the measuring rod 300. Such a structural design is conducive to fixing the laser measuring device fixture 100 for the centering instrument on the measuring rod 300 of the centering instrument to achieve stable support.
[0045] In each embodiment, Figure 1 and Figure 2As shown, the fixed clamp 110 is connected to the support frame 120 to form a clamping area 180, and the fixed clamp 110 is used to cooperate with the support frame 120 to jointly fix the hand-held laser rangefinder 200 in the clamping area 180. As an example, the fixed clamp 110 is adjustably connected to the support frame 120, that is, the size of the clamping area 180 is adjustable, or the opening of the clamping area 180 is adjustable, so that the laser measurement device clamp 100 for the alignment instrument can be applicable to various different specifications of hand-held laser rangefinders 200. Moreover, through the structural design of the locking mechanism 140 cooperating with the adjustment mechanism 130, the laser measurement device clamp 100 for the alignment instrument can be applicable to various different specifications of alignment instruments, thus greatly improving the applicability of the laser measurement device clamp 100 for the alignment instrument.
[0046] In each embodiment, as Figure 1 and Figure 2 shown, the support frame 120 is movably connected to the adjustment mechanism 130, and is used to adjust the relative position between the fixed clamp 110 and the adjustment mechanism 130, so as to adjust the relative position between the hand-held laser rangefinder 200 and the measuring rod 300. With such a structural design, on the premise of securely installing the hand-held laser rangefinder 200, the laser measurement device clamp 100 for the alignment instrument is beneficial to fix the hand-held laser rangefinder 200 on the measuring rod 300 of the alignment instrument, realizing stable support, solving the problem of large measurement errors of traditional steel tapes, realizing the rapid application of the laser rangefinder in the alignment operation, significantly improving the measurement accuracy and operation efficiency, and is especially suitable for the alignment instrument of wind turbine generators.
[0047] In one of the embodiments, as Figure 3 and Figure 4 shown, the locking mechanism 140 is installed on the adjustment mechanism 130, and is used to loosen or tighten the opening size of the adjustment mechanism 130, so as to lock the adjustment mechanism 130 on the measuring rod 300 or loosen it from the measuring rod 300, and further make the laser measurement device clamp 100 for the alignment instrument lock on the measuring rod 300 or loosen it from the measuring rod 300; Exemplarily, the locking mechanism 140 is a non-detachable locking mechanism, that is, it has an anti-detachment design, and can only be loosened or tightened after being installed on the adjustment mechanism 130, and cannot be detached; Only an unlocking tool can be used to loosen it from the adjustment mechanism 130. With such a structural design, it has the advantages of simple structure and convenient use; cooperating with the locking mechanism 140 with an anti-detachment design is beneficial to protect the laser measurement device clamp 100 for the alignment instrument and the hand-held laser rangefinder 200 during use.
[0048] In one of the embodiments, as Figure 4 andFigure 5 As shown, the support frame 120 is movably connected to the adjustment mechanism 130 through a connecting member 124. In one embodiment, the connecting member 124 is a slide rail or a rotating joint. With such a structural design, the adjustment mechanism 130 can rotate relative to the support frame 120, that is, in addition to translating or rotating relative to the measuring rod 300 of the centering instrument, the adjustment mechanism 130 can also rotate relative to the support frame 120, so that the laser emission angle of the handheld laser rangefinder 200, that is, the ranging angle, has a larger angle adjustment range relative to the measuring rod 300 of the centering instrument, so it is easy to use and suitable for various outdoor application environments of wind turbines, especially it can realize rapid assembly and rapid measurement, which greatly improves the operational efficiency of centering measurement.
[0049] In one embodiment, if Figure 5 and Figure 6 As shown, the support frame 120 is further provided with a first support block 121, the first support block 121 is connected to the connecting member 124, and the first support block 121 is used to cooperate with the fixing fixture 110 to form the clamping area 180, and jointly clamp and fix the handheld laser rangefinder 200 in the clamping area 180. In this embodiment, the support frame 120 is further provided with a second support block 122 and a third support block 123; the second support block 122 is connected to the third support block 123 through the connecting member 124; the first support block 121 is connected to the second support block 122, and is connected to the connecting member 124 through the second support block 122; the fixing fixture 110 is connected to the third support block 123. With such a structural design, on the one hand, the structure of the support frame 120 is simple, the connection is convenient, and it is easy to assemble; on the other hand, by designing various first support blocks 121, it can adapt to different handheld laser rangefinders 200, thereby improving the versatility of the laser measurement device fixture 100 for the centering instrument.
[0050] In one embodiment, if Figure 1 and Figure 4 As shown, the fixing fixture 110 is connected to the support frame 120 by a bolt 150. In this embodiment, the fixing fixture 110 is connected to the third support block 123 of the support frame 120 by a bolt 150. In other embodiments, the fixing fixture 110 can be connected to the support frame 120 or its third support block 123 by a buckle. Alternatively, in one embodiment, the fixing fixture 110 can be connected to the support frame 120 or its third support block 123 by a bolt 150 and a buckle. The rest of the embodiments are similar and will not be described in detail.
[0051] To enhance the clamping force between the fixed fixture 110 and the support frame 120, exemplarily, in one embodiment, as Figure 7 and Figure 8 shown, the laser measurement device fixture 100 is provided with a screw tube 160 in the support frame 120 or its third support block 123. The fixed fixture 110 is screwed to the screw tube 160 in the support frame 120 or its third support block 123 through a bolt 150. Such a structural design can, on the one hand, reasonably adjust the size of the clamping area 180 through the cooperation of the bolt 150 and the screw tube 160, so as to adapt to various specifications of the handheld laser rangefinder 200, and enhance the adaptability and versatility of the laser measurement device fixture 100 for the alignment instrument; on the other hand, through the cooperation of the bolt 150 and the screw tube 160, the clamping force between the fixed fixture 110 and the support frame 120 or its third support block 123 can be increased, making the fixation of the handheld laser rangefinder 200 by the laser measurement device fixture 100 for the alignment instrument more stable and reliable.
[0052] In one embodiment, an alignment instrument includes a handheld laser rangefinder 200, a measuring rod 300, and a laser measurement device fixture 100; exemplarily, the handheld laser rangefinder 200 is disposed in the fixed fixture 110 of the laser measurement device fixture 100; the adjustment mechanism 130 of the laser measurement device fixture 100 is movably disposed on the measuring rod 300 and is used to adjust the handheld laser rangefinder 200 and then fix the handheld laser rangefinder 200. In one embodiment, the alignment instrument is a laser alignment instrument for a wind turbine generator set. The alignment instrument can fix the handheld laser rangefinder 200 on the measuring rod 300 of the alignment instrument through the cooperation of the fixed fixture 110, the support frame 120, the adjustment mechanism 130, and the locking mechanism 140, realizing stable support, solving the problem of large measurement errors of traditional steel tape measures, realizing the rapid application of the laser rangefinder in alignment operations, significantly improving the measurement accuracy and operation efficiency, and is particularly suitable for use in the alignment instrument of a wind turbine generator set.
[0053] In one embodiment, an alignment instrument includes a handheld laser rangefinder 200, a measuring rod 300, and a laser measurement device fixture 100; wherein, the laser measurement device fixture 100 can be the laser measurement device fixture 100 described in any embodiment. Since the alignment instrument adopts the laser measurement device fixture 100 for the alignment instrument, the alignment instrument also has the beneficial technical effects of the laser measurement device fixture 100 for the alignment instrument, which will not be elaborated here.
[0054] As an example, a laser alignment instrument for a wind turbine generator includes a handheld laser rangefinder 200, a measuring rod 300, and the laser measuring device fixture 100 described in any of the embodiments. It can fix the handheld laser rangefinder 200 on the measuring support rod of the alignment instrument, that is, the measuring rod 300, solves the problem of large measurement errors of traditional steel tape measures, realizes the application of the laser rangefinder in the alignment operation, and improves the measurement accuracy and operation efficiency. Among them, the mechanical structure components of the laser measuring device fixture 100 include a fixed fixture 110, a support frame 120, and an adjustment mechanism 130. The fixed fixture 110 is used to firmly fix the handheld laser rangefinder 200 on the measuring rod of the alignment instrument. The support frame 120 is used to support the fixed fixture 110 and ensure the stability of the laser rangefinder, that is, the handheld laser rangefinder 200, during the measurement process. The adjustment mechanism 130 is used to adjust the measurement angle and direction of the handheld laser rangefinder 200 to meet different measurement requirements.
[0055] The following example illustrates the connection relationship and positional relationship between the components of the laser measuring device fixture 100. The fixed fixture 110 is connected to the support frame 120 through bolts 150 and buckles, and the support frame 120 is connected to the adjustment mechanism 130 through a slide rail or a rotary joint. The adjustment mechanism 130 is installed on the measuring rod 300 of the alignment instrument, can move along the direction of the measuring rod 300, and can be locked in the required position.
[0056] The following example illustrates the working principle and working process of the laser measuring device fixture 100. First, fix the handheld laser rangefinder 200 in the fixed fixture 110, and adjust the direction and angle of the laser rangefinder 200 through the adjustment mechanism. Then start the handheld laser rangefinder 200 to measure the distance between two laser emitters, as well as the distances from the laser emitter to the front shaft support and the rear support of the generator. Then record the measurement results to complete the measurement operation. Such a design overcomes the problem of large measurement errors of traditional steel tape measures, realizes the application of the handheld laser rangefinder 200 in the alignment operation, especially for the alignment operation of wind turbine generators, and significantly improves the measurement accuracy and operation efficiency.
