In engineering, the jacking method is commonly used for calibration. When measuring, the measurement position of the shaft section and the jacking position of the hydraulic jack must be determined first through the calibration and positioning device.

[0020] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] During existing shafting installation and calibration procedures, multiple positioning devices are required to locate shafts or shaft segments of varying diameters to determine the measurement position and the jacking position. Frequent equipment changes slow down the calibration process and lead to large errors, seriously impacting the shaft's service life. To address this technical issue, the present invention provides a shafting calibration and positioning device that facilitates operation, adapts to shafts or shaft segments of varying diameters, and ensures efficient calibration and measurement.

[0022] The present invention is described by taking the application of the calibration and positioning device to the installation and calibration of a ship shaft system as an example. It can be understood that the working principle of the calibration and positioning device when applied to shaft systems of other equipment is the same as that when applied to ship shaft systems.

[0023] like Figures 1 to 6As shown, the present invention provides a shaft system calibration and positioning device for determining the measurement position of a shaft or shaft segment and the lifting position of a jack. The positioning device includes a frame 100, a measurement module 200 and an adjustment module 300.

[0024] The measuring module 200 is arranged on the frame 100 and is used to determine the measuring position and the lifting position; the adjustment module 300 includes a moving mechanism 310 and a clamping mechanism 320, the moving mechanism 310 is arranged on the frame 100, and the clamping mechanism 320 is transmission-connected to the moving mechanism 310, and the clamping mechanism 320 forms a clamping space for the measured shaft to pass through. The clamping mechanism 320 is displaced under the drive of the moving mechanism 310 to increase or decrease the clamping space, thereby achieving the matching of the clamping space with the measured shafts of different diameters.

[0025] The shaft system calibration and positioning device provided by the present invention can drive the clamping mechanism 320 to move through the provided moving mechanism 310. In this way, the clamping space used to clamp and fix the shaft to be measured becomes adjustable, and the size of the clamping space can be adjusted accordingly according to the diameter of the shaft or shaft segment to match the diameter of the shaft or shaft segment. There is no need to use multiple different devices for shafts or shaft segments of different diameters, and there is no need for multiple installations, which greatly improves the calibration efficiency. At the same time, one-time installation also avoids operational errors and measurement errors that are prone to occur in multiple measurements. It also improves measurement accuracy on the basis of shortening the measurement time, which is conducive to the shaft system to achieve its best performance. In addition, the use of the positioning device of the present invention also reduces the burden on staff.

[0026] Furthermore, during the installation and calibration of a ship's shafting system, multiple data must be collected, such as the shafting's measurement position, the shafting's jacking position, and other data. The prior art requires multiple devices to repeatedly turn the shafts to perform measurements. Due to the presence of other shafting accessories, such as bearing seats, around the shafting system, the shafting calibration space is narrow, causing significant inconvenience. The positioning device provided by the present invention integrates various calibration parameter measurement devices into a single set of equipment based on existing measurement methods. Specifically, the device utilizes an integrated frame 100, on which a measurement module 200 and an adjustment module 300 are integrated. This device has the advantages of simple structure and convenient operation, making it easy for novices to operate.

[0027] Specifically, in one embodiment, the frame 100 is composed of a cylinder 110 and a base 120. The cylinder 110 is fixedly arranged on the top of the base 120. The cylinder 110 and the base 120 are an integrally formed structure.

[0028] In one embodiment, the measuring module 200 includes a pendulum unit 210, a bracket unit 220, and a laser rangefinder (not shown). The pendulum unit 210 is disposed inside the cylinder 110 and is used to determine the highest point of the shaft or shaft segment. One end of the bracket unit 220 is fixedly connected to the side wall of the base 120, and the other end thereof is located at the bottom of the clamping mechanism 320 and is used to determine the lifting position of the shaft or shaft segment. A through hole 111 is formed in the side wall of the cylinder 110, and the laser rangefinder is installed in the through hole 111. When the positioning device determines the highest point of the shaft or shaft segment through the pendulum unit 210, the laser rangefinder is turned on to measure the highest point.

[0029] In one embodiment, the pendulum unit 210 includes a hinge seat 211, a rotating shaft 212, two end plates 213, a cross bar 214, a vertical bar 215 and a gravity ball 216. The hinge seat 211 is arranged on the inner top wall of the cylinder 110, the rotating shaft 212 is hinged to the hinge seat 211, one end of the two end plates 213 is respectively fixed to the two ends of the rotating shaft 212, the two ends of the cross bar 214 are respectively fixedly connected to the other ends of the two end plates 213, one end of the vertical bar 215 is fixed to the middle of the cross bar 214, and the other end of the vertical bar 215 is fixedly connected to the gravity ball 216.

[0030] In this embodiment, the rotating shaft 212 can rotate around the hinge seat 211, driving the end plates 213 on both sides to rotate, and the gravity ball 216 swings toward the lowest point under the action of gravity. By adjusting the positioning device and the indication of the pendulum, the highest point of the shaft or shaft segment can be determined.

[0031] In one embodiment, the bracket unit 220 includes a first connecting rod 221, a second connecting rod 222, a telescopic rod 223 and a cross bracket 224, one end of the first connecting rod 221 is fixed to the outer wall of the base 120, and the other end thereof is connected to one end of the telescopic rod 223, the other end of the telescopic rod 223 is connected to one end of the second connecting rod 222, and the other end of the second connecting rod 222 is fixedly connected to the cross bracket 224.

[0032] In this embodiment, the cross bracket 224 can be moved up and down by adjusting the telescopic rod 223, and its position with the bottom of the shaft is adjusted so that the cross bracket 224 can be close to the bottom of the shaft. At the same time, the intersection center point of the cross bracket 224 is on the same straight line as the highest point of the shaft or shaft segment determined by the pendulum unit 210. The center point of the cross bracket 224 is the lifting position of the jack, which eliminates a series of complicated operations such as complex turning, and the measured data has a high credibility.

[0033] In one embodiment, the adjustment module 300 includes a moving mechanism 310 and a clamping mechanism 320, and the moving mechanism 310 and the clamping mechanism 320 are arranged inside the base 120. The moving mechanism 310 includes two rotating units 311, a transmission member 312 and a driving member 313. The two rotating units 311 are respectively slidably arranged on the frame 100, specifically, are arranged on the two side walls of the base 120, and are transmission-connected to the clamping mechanism 320. The two ends of the transmission member 312 are respectively fixedly connected to the two rotating units 311, one end of the driving member 313 is connected to the transmission member 312, and the other end of the driving member 313 is arranged outside the frame 100.

[0034] In this embodiment, the driving member 313 drives the transmission member 312 to move under the action of external force, and then drives the two rotating units 311 to move, so that the clamping mechanism 320 also moves accordingly, achieving a change in the size of the clamping space.

[0035] In one embodiment, Figure 3 and Figure 4 As shown, each of the rotating units 311 includes an outer disk 3111 and an inner disk 3112. A circular hole is provided on the side wall of the frame 100. The outer disk 3111 is slidably arranged in the circular hole. A mounting hole 3111a is formed in the middle of the outer disk 3111. The outer disk 3111 is provided with a first placement groove 3111b extending from the mounting hole 3111a toward the outer edge of the outer disk 3111. A plurality of the first placement grooves 3111b are evenly arranged along the circumference of the mounting hole 3111a and are inclined clockwise to the central axis of the mounting hole 3111a.

[0036] The inner disk 3112 is arranged in the mounting hole 3111a, and the inner disk 3112 is provided with a second placement groove 3112a extending from its center hole toward the outer edge of the inner disk 3112. The second placement groove 3112a corresponds to and is connected to the first placement groove 3111b one by one, and the two ends of the clamping mechanism 320 are respectively arranged in the first placement groove 3111b and the second placement groove 3112a.

[0037] In one embodiment, the clamping mechanism 320 includes a plurality of telescopic blocks 321, the two ends of which are respectively arranged in the first placement groove 3111b and the second placement groove 3112a and abut against the groove wall of the first placement groove 3111b, and the area enclosed by one end of the plurality of telescopic blocks 321 away from the first placement groove 3111b constitutes the clamping space.

[0038] In one embodiment, the clamping mechanism 320 also includes a stop block 322 and an elastic member 323, and one side wall of each of the second placement grooves 3112a extends away from the other side wall to form a third placement groove 3112b, one end of the stop block 322 is fixed to the telescopic block 323, and the other end thereof is arranged in the third placement groove 3112b, and the two ends of the elastic member 323 are respectively fixedly connected to the stop block 322 and the bottom wall of the third placement groove 3112b.

[0039] In this embodiment, the driving member 313 can drive the transmission member 312 to move, thereby driving the outer disk 3111 to rotate, and the side wall of the first placement groove 3111b pushes the telescopic block 321 to move in the second placement groove 3112a, and the elastic member 323 is pressed in the third placement groove 3112b, so that the clamping space formed at the end of multiple telescopic blocks 321 becomes smaller; when the diameter of the shaft or shaft segment changes, the driving member 313 is released, and the outer disk 3111 rotates counterclockwise at this time, and the elastic member 323 bounces the block 322, thereby driving the telescopic block 321 to move outward, releasing the shaft, and repeating the above action to clamp the new shaft.

[0040] In one embodiment, Figure 5 and Figure 6 As shown, each of the rotating units 311 includes a gear 3113, a first rack 3114 and a second rack 3115. The side wall of the frame 100 is provided with a first slide groove and a second slide groove arranged up and down. The first rack 3114 is arranged in the first slide groove, and the second rack 3115 is arranged in the second slide groove. The gear 3113 is respectively engaged with the first rack 3114 and the second rack 3115.

[0041] Correspondingly, the clamping mechanism 320 includes four strip-shaped claw clamps 324, one end of each strip-shaped claw clamp 324 is fixedly connected to one end of the first rack 3114 and the second rack 3115 on each side, and the area enclosed by the other end of each strip-shaped claw clamp 324 constitutes the clamping space.

[0042] In this embodiment, the driving member 313 is a rotating nut, which can drive the transmission member to rotate by rotating the nut, and then drive the gear 3113 to rotate, thereby driving the first rack 3114 and the second rack 3115 engaged with it to move, thereby realizing the adjustment of the size of the clamping space surrounded by the strip-shaped claw clamp 324 to adapt to shafts or shaft segments of different diameters.

[0043] In summary, the shaft system calibration and positioning device provided by the present invention solves the measurement problem for shafts or shaft segments of different diameters through the moving mechanism 310 and the clamping mechanism 320, shortens the measurement time and improves the measurement accuracy; at the same time, the positioning device of the present invention integrates multiple measuring devices into one device, has a simple structure and is easy to operate, which solves the problem of high entry threshold.
