Description

Technical Field

[0001] This application relates to the field of cylinder verticality measurement technology, and in particular to a dedicated cylinder verticality measuring device. Background Technology

[0002] The verticality measurement of the outer cylinder of the circulating water pump is directly related to the stability, sealing, and lifespan of the equipment. One end of the circulating water pump is equipped with a stuffing box inner hole, and the other end is equipped with a suction inlet inner hole. Both ends of the outer cylinder of the circulating water pump are equipped with multiple connection holes spaced apart circumferentially.

[0003] In related technologies, the verticality of the outer cylinder of a circulating water pump is generally measured by using an inclinometer. The inclinometer is attached to the vertical direction of the outer wall of the outer cylinder to measure the verticality of the outer cylinder. However, the above measurement method is difficult to measure the verticality of the outer shell axis.

[0004] Therefore, it is necessary to propose a special measuring device for the verticality of the cylinder to measure the verticality of the outer cylinder axis of the circulating water pump, which has become an important technical problem that urgently needs to be solved. Utility Model Content

[0005] This application provides a dedicated measuring device for the verticality of a cylinder, which aims to solve the problem in the prior art that it is difficult to measure the verticality of the axis of the circulating water pump casing using an inclinometer.

[0006] To achieve the above objectives, this application proposes a dedicated measuring device for the verticality of a cylinder, comprising: a measuring base; a support platform disposed on the measuring base; a rope-releasing shaft rotatably disposed on the support platform, with a steel wire wound on the rope-releasing shaft and a pendulum at the end of the steel wire; a transverse movement structure movably disposed on the measuring base, which drives the support platform to move laterally; and a longitudinal movement structure disposed on the measuring base, which drives the transverse movement structure to move longitudinally.

[0007] In some embodiments, the longitudinal movement structure includes: a longitudinal movement seat connected to a measuring seat; a longitudinal movement screw rotatably disposed within the longitudinal movement seat; and a longitudinal movement nut block screwed to the longitudinal movement screw.

[0008] In some embodiments, the transverse structure includes: a transverse seat connected to a longitudinal nut block; a transverse screw rotatably disposed within the transverse seat; and a transverse nut block connected to a support platform.

[0009] In some embodiments, it further includes: a slide rail, wherein the longitudinal sliding seat is provided with a slide rail; and a slide groove, wherein the transverse sliding seat is provided with a slide groove adapted to the slide rail.

[0010] In some embodiments, the system further includes: a plurality of reinforcing blocks, which are spaced apart within the transverse support, and a transverse nut block is located between two reinforcing blocks.

[0011] In some embodiments, the device further includes a handwheel, with handwheels provided at the ends of the rope release shaft, the longitudinal screw, and the transverse screw.

[0012] This application proposes a dedicated measuring device for the verticality of a cylinder, comprising: a measuring base; a support platform, the support platform being mounted on the measuring base; a rope-releasing shaft, rotatably mounted on the support platform, with a steel wire wound around the shaft and a pendulum at the end of the wire; a transverse movement structure, movably mounted on the measuring base, which drives the support platform to move laterally; and a longitudinal movement structure, mounted on the measuring base, which drives the transverse movement structure to move longitudinally. The measuring base is securely installed onto the inner hole of the outer cylinder's filling culvert using the measuring base and locking bolts. The rope-releasing shaft is rotated to allow the pendulum to pass over the inner hole of the suction inlet. An inside micrometer is used to accurately measure the overlap between the steel wire and the center of the inner hole of the outer cylinder's filling culvert. When the steel wire does not overlap with the center of the inner hole, the position of the steel wire is adjusted using the transverse and longitudinal movement structures until the deviation between the steel wire and the center of the inner hole is less than 0.5 mm. At this point, the perpendicularity of the outer cylinder axis can be obtained by measuring the deviation between the center of the inner hole of the outer cylinder suction inlet and the steel wire.

[0022] See Figure 1 , Figure 2 and Figure 3 As shown, this application proposes a special measuring device for the verticality of a cylinder, comprising: a measuring base 1; a support platform 7, the support platform 7 being disposed on the measuring base 1; a rope-releasing shaft 10, the rope-releasing shaft 10 being rotatably disposed on the support platform 7, a steel wire 9 being wound on the rope-releasing shaft 10, and a pendulum being disposed at the end of the steel wire 9; a transverse moving structure, the transverse moving structure being movably disposed on the measuring base 1, the transverse moving structure driving the support platform 7 to move laterally; and a longitudinal moving structure, the longitudinal moving structure being disposed on the measuring base 1, the longitudinal moving structure driving the transverse moving structure to move longitudinally.

[0023] The measuring base 1 is the structural foundation of a special measuring device for cylinder verticality. All other structures on the special measuring device for cylinder verticality are directly or indirectly connected to the measuring base 1. The measuring base 1 is provided with two threaded holes for fixing the measuring base 1. Locking bolts 2 are screwed into the two threaded holes. The locking bolts 2 are screwed into the connecting holes of the inner hole of the packing duct of the outer cylinder of the circulating water pump, thereby firmly fixing the measuring base 1 to the outer cylinder, which facilitates the subsequent verticality measurement work and also helps to improve the stability of the verticality measurement results.

[0024] The support platform 7 is equipped with a bearing seat 8. The rope-releasing shaft 10 is rotatably mounted on the support platform 7 via the bearing seat 8. One end of the steel wire 9 is welded to the rope-releasing shaft 10, and the other end of the steel wire 9 is connected to a pendulum. The pendulum is used to straighten the steel wire 9, and part of the steel wire 9 is wound around the rope-releasing shaft 10. The measuring base 1, the transverse movement structure, and the longitudinal movement structure are all equipped with large through holes for the pendulum to pass through. The diameter of the large through hole is larger than the outer diameter of the pendulum.

[0025] Specifically, the measuring seat 1 is securely installed onto the inner hole of the outer cylinder's filling culvert using the measuring seat 1 and locking bolt 2. The rope release shaft 10 is rotated to allow the wire to pass over the inner hole of the suction inlet. An inside micrometer is used to precisely measure the overlap between the center of the steel wire 9 and the center of the inner hole of the outer cylinder's filling culvert. If the steel wire 9 does not overlap with the center of the inner hole, the position of the steel wire 9 is adjusted using the transverse and longitudinal movement structures until the deviation between the steel wire 9 and the center of the inner hole of the outer cylinder's filling culvert is less than 0.5 mm. At this point, measuring the deviation between the center of the inner hole of the outer cylinder's suction inlet and the steel wire 9 yields the perpendicularity of the outer cylinder's axis.

[0026] Wherein, the horizontal direction refers to the length direction of measuring base 1, and the vertical direction refers to the width direction of measuring base 1. When the perpendicularity of the outer cylinder axis does not meet the standard, the shims of the outer cylinder can be adjusted to make the deviation between the steel wire 9 and the center of the inner hole of the outer cylinder suction port less than 0.5mm, at which point the perpendicularity of the outer cylinder is qualified.

[0027] See Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the longitudinal movement structure includes: a longitudinal movement seat 3, which is connected to the measuring seat 1; the longitudinal movement seat 3 is welded to the measuring seat 1. A longitudinal movement screw 6 is rotatably disposed within the longitudinal movement seat 3; the longitudinal movement screw 6 is rotatably mounted within the longitudinal movement seat 3 via bearings; and a longitudinal movement nut block is screwed to the longitudinal movement screw 6 and connected to the transverse movement structure. Rotating the longitudinal movement screw 6 drives the longitudinal movement nut block to reciprocate longitudinally, thereby driving the transverse movement structure to reciprocate longitudinally.

[0028] See Figure 1 and Figure 3As shown, in some embodiments, the transverse movement structure includes: a transverse movement seat 13 connected to a longitudinal movement nut block; the transverse movement seat 13 can reciprocate longitudinally under the drive of the longitudinal movement nut block; a transverse movement screw rotatably disposed within the transverse movement seat 13; the transverse movement screw is rotatably disposed within the transverse movement seat 13 via a bearing; and a transverse movement nut block connected to a support platform 7. Rotating the transverse movement screw drives the transverse movement nut block to reciprocate laterally, thereby driving the support platform 7 to reciprocate laterally.

[0029] In this embodiment, by setting a longitudinal and a transverse structure, the support platform 7 can be adjusted to any position in the plane, thereby allowing the steel wire 9 to be adjusted to any position in the plane, so that the steel wire 9 can coincide with the center of the inner hole of the outer cylinder filling culvert.

[0030] See Figure 1 and Figure 3 As shown, in some embodiments, it further includes: a slide rail 4, which is provided on the longitudinal sliding seat 3; and a slide groove, which is provided on the transverse sliding seat 13 to adapt to the slide rail 4. The cooperation of the slide rail 4 and the slide groove improves the stability of the transverse sliding seat 13 in longitudinal movement.

[0031] In this embodiment, the slide rail 4 is provided with a longitudinal sliding groove with an open top. The longitudinal sliding nut block is movably disposed in the longitudinal sliding groove, and a reinforcing rib 5 is provided in the longitudinal sliding groove, which helps to improve the structural rigidity of the slide rail 4 and prevent the slide rail 4 from deforming. Preferably, the cross-section of the slide rail 4 is dovetail-shaped, and the slide rail 4 and the longitudinal sliding seat 3 are integrally formed.

[0032] See Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, it further includes: a plurality of reinforcing blocks 12, which are spaced apart in the transverse shift seat 13, and a transverse shift nut block is located between two reinforcing blocks 12. The transverse shift seat 13 is provided with a transverse shift groove with an upper opening, and the transverse shift nut block is movably disposed in the transverse shift groove. The plurality of reinforcing blocks 12 can first improve the structural rigidity of the transverse shift seat 13, and secondly, the reinforcing blocks 12 can also guide the movement of the transverse shift nut block.

[0033] In this embodiment, a connecting screw 15 is provided on the transverse nut block, and a through hole is provided at the bottom end of the support platform 7. The connecting screw 15 on the transverse nut block passes through the through hole at the bottom end of the support platform 7 and is then locked by a locking nut 16, thereby installing the support platform 7 onto the transverse nut block. Preferably, four reinforcing blocks 12 are provided, and the four reinforcing blocks 12 enclose three guide spaces 17. The transverse nut block is located in one guide space 17, and sliders are provided in the remaining two guide spaces 17. A connecting screw 15 is provided at the upper end of the slider, and a through hole is provided at the bottom end of the support platform 7. The connecting screw 15 on the slider passes through the through hole at the bottom end of the support platform 7 and is then locked by a locking nut 16, further improving the stability of the movement of the support platform 7.

[0034] See Figure 1 and Figure 3 As shown, in some embodiments, it further includes: a handwheel 11, with handwheels 11 provided at the ends of the rope release shaft 10, the longitudinal screw 6, and the transverse screw.

Preferably, a handle 18 is also provided on the handwheel 11.
