It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

Referring to fig. 1 and 5 together, a description will now be given of a high-precision automatic inclination measuring system according to the present invention. The high-precision automatic inclination measuring system comprises a movable base 10, a take-up and pay-off mechanism 20, a sliding probe 30, a fixed cylinder 40, a rotary cylinder 60, a driving assembly 70 and a matched controller. The pay-off and take-up mechanism 20 is provided on the moving base 10, and a cable 80 is stored in the pay-off and take-up mechanism 20. The slide type probe 30 is connected to a cable 80 guided out by the pay-off and take-up mechanism 20. The fixed cylinder 40 is arranged on the take-up and pay-off mechanism 20 and is arranged along the vertical direction, and the bottom end of the fixed cylinder 40 is provided with a positioning head 50 which can be matched with the top end of the inclinometer pipe 90. The rotary cylinder 60 is rotatably provided in the fixed cylinder 40 and above the positioning head 50, and can store the slide type probe 30. The drive assembly 70 is disposed on the stationary drum 40 and is in power connection with the rotating drum 60.

Regarding the high-precision automatic inclination measuring system provided in this embodiment, the working principle thereof is as follows: as the wire winding and unwinding mechanism 20 performs wire winding, the sliding probe 30 enters the inclinometer 90, and as the wire winding and unwinding mechanism 20 performs wire winding, the sliding probe 30 moves out of the inclinometer 90 to complete one measurement. After the first measurement and before the second measurement of the sliding probe 30, the driving assembly 70 drives the rotary cylinder 60 and the sliding probe 30 inside to rotate 180 °.

In this process, at the set initial position, the front measurement is performed once, the data a is recorded, and after the sliding probe 30 is rotated 180 °, the second measurement is performed, the data B is recorded, according to the formula: c= (a+b)/2, C is the correction value of zero drift. Assuming that the angle measured by the sliding probe 30 for the first time is 3 ° at the set initial position, and the angle measured by the sliding probe 30 is-1 ° at the set initial position after 180 ° rotation, the actual angle at the initial position is the median value of the two data, i.e., 1 °.

Compared with the prior art, the high-precision automatic inclination measuring system provided by the embodiment has the advantages that the moving base 10 can ensure moving convenience, the wire winding and unwinding mechanism 20 arranged on the moving base 10 and the sliding probe 30 connected with the cable 80 can ensure inclination measuring work, the positioning head 50 arranged at the bottom end of the fixed cylinder 40 can ensure detachable connection with the inclinometer pipe 90 to be measured, further, the sliding probe 30 in the rotating cylinder 60 can automatically drop into the inclinometer pipe 90 under the work of the wire winding and unwinding mechanism 20, the rotating cylinder 60 arranged in the fixed cylinder 40 can ensure storage of the sliding probe 30, and meanwhile, the sliding probe 30 can be rotated 180 degrees between two times of measurement, so that zero drift is effectively eliminated. The high-precision automatic inclination measuring system provided by the embodiment can realize automatic work, saves manpower, can effectively eliminate zero drift at the same time, and has high measuring precision and strong practicability.

In addition, it should be noted that the wire winding and unwinding mechanism 20 will be intermittently stopped during the wire winding process, so as to ensure that the slide probe 30 detects the inclination values at different positions.

In some embodiments, the positioning head 50 may have a structure as shown in fig. 2 and 4. Referring to fig. 2 and 4, the positioning head 50 is rotatably disposed at the bottom end of the fixed cylinder 40, the positioning head 50 has a through cavity disposed along a vertical direction, and two first guide grooves 53 for sliding the sliding probe 30 are disposed on the inner wall of the through cavity. The positioning head 50 mainly can ensure the connection with the inclined tube 90 to be detected, the arrangement of the through cavity can ensure that the through cavity is sleeved on the inclined tube 90, and the two first guide grooves 53 are smoothly butted with the two sliding grooves in the inclined tube 90 so as to ensure that the sliding probe 30 can be smoothly guided into the inclined tube 90, and the structure is simple and the practicability is strong.

It should be noted that chamfers may be provided at the ends of both the first guide grooves 53 to prevent the sliding probe 30 from interfering with the corners of the first guide grooves 53.

In this embodiment, a thrust bearing is provided between the positioning head 50 and the fixed cylinder 40 in a conventional manner.

In some embodiments, the positioning head 50 may be configured as shown in fig. 4. Referring to fig. 4, the through cavity includes a first cylindrical cavity 51 and a second cylindrical cavity 52 communicating with the first cylindrical cavity 51, the first cylindrical cavity 51 is located below the second cylindrical cavity 52, and the diameter of the first cylindrical cavity 51 is smaller than that of the second cylindrical cavity 52, so that the top end of the inclinometer pipe 90 can be inserted, and an annular platform is formed between the first cylindrical cavity 51 and the second cylindrical cavity 52.

Wherein two locating ends 54 are provided on the annular platform which can be adapted to the two opposing runners in the inclinometer pipe 90.

The second cylindrical cavity 52 mainly can guarantee to be sleeved on the top end of the inclined tube 90 to be detected, the annular platform can guarantee to be abutted with the inclined tube 90 so as to guarantee that the sleeved length is fixed, and the positioning ends 54 arranged on the annular platform can be respectively inserted into the other two sliding grooves of the inclined tube 90, because the inclined tube 90 is usually provided with four sliding grooves, the two positioning ends 54 respectively correspond to the two opposite sliding grooves, the other two sliding grooves of the inclined tube 90 can be further guaranteed to be communicated with the two first guide grooves 53, and the inclined tube 90 can be further guaranteed to automatically, smoothly and stably pass through.

In some embodiments, the rotating cylinder 60 may be configured as shown in fig. 3. Referring to fig. 3, the bottom end of the rotary cylinder 60 abuts against the top end of the positioning head 50, the rotary cylinder 60 has a cylinder chamber 61 communicating with the through chamber, and two second guide grooves 62 are provided in the cylinder chamber 61 to be fitted with the respective first guide grooves 53.

First, the second guide groove 62 can ensure engagement with the first guide groove 53, thereby ensuring that the sliding probe 30 can enter the first guide groove 53. In addition, the second guide groove 62 can ensure circumferential limitation of the sliding probe 30, so as to ensure that the sliding probe 30 can synchronously rotate along with the rotary cylinder 60.

In the present embodiment, a thrust bearing is provided between the rotary cylinder 60 and the stationary cylinder 40 in a conventional manner.

In some embodiments, the drive assembly 70 may be configured as shown in fig. 2-3. Referring to fig. 2 to 3, the driving assembly 70 includes a first one-way bearing 71, a ring gear 72, a power gear 73, and a servo motor 74. The first one-way bearing 71 has an inner ring and an outer ring, and the inner ring of the first one-way bearing 71 is fixedly sleeved on the rotary cylinder 60. The ring gear 72 is fixedly fitted over the outer ring of the first one-way bearing 71. The power gear 73 is rotatably provided on the fixed cylinder 40 and is meshed with the ring gear 72. The servo motor 74 is fixedly arranged on the fixed cylinder 40 and is in power connection with the power gear 73, and the servo motor 74 is electrically connected with the controller and can drive the rotary cylinder 60 to rotate 180 degrees.

The power gear 73 is driven to rotate by the servo motor 74, and then the rotary cylinder 60 is directly driven to rotate 180 degrees by the ring gear 72 and the first one-way bearing 71, so that the sliding probe 30 can be effectively ensured to rotate 180 degrees.

Because the four sliding grooves are not fixed when the inclinometer 90 is embedded, and the positioning head 50 rotates after being fixed by the position of the moving base 10, after the inclinometer 90 is abutted with the inclinometer to be measured, the two first guide grooves 53 and the two second guide grooves 62 may not be aligned, and the rotating drum 60 needs to be rotated at this time, but in actual operation, the servo motor 74 needs to involve self-locking, so that in order to ensure the rotation of the rotating drum 60, the two second guide grooves 62 correspond to the two first guide grooves 53, and the first one-way bearing 71 is provided, that is, after the rotating drum 60 reversely rotates, the second guide grooves 62 correspond to the first guide grooves 53, and meanwhile, the rotation of the ring gear 72 is not affected, and after the rotating drum 60 positively rotates under the driving of the ring gear 72, the sliding probe 30 is controlled to rotate 180 °.

In this process, since manual control is required during the process of docking with the inclined tube 90 to be tested, in order to facilitate the operator to observe whether the second guide groove 62 is docked with the first guide groove 53, a marking strip may be disposed on the outer wall of the positioning head 50, and meanwhile, a marking strip may be disposed on the outer wall of the rotating cylinder 60 extending out of the fixed cylinder 40, where the two are in the same vertical line, i.e. the second guide groove 62 corresponds to the first guide groove 53.

In some embodiments, the drive assembly 70 may be configured as shown in FIG. 2. Referring to fig. 2, the drive assembly 70 further includes a second one-way bearing 75 and damping.

The damping is in threaded connection with the fixed cylinder 40, and one end abuts against the outer ring of the second one-way bearing 75.

In this embodiment, since the inner ring of the first one-way bearing 71 can rotate reversely during the adjustment of the alignment sleeve 60, automatic rotation may occur after the alignment, which may further cause the second guide groove 62 to deviate from the first guide groove 53. The second one-way bearing 75 may be locked by damping at this time to prevent the inner race of the first one-way bearing 71 from automatically reversing rotation with the rotary drum 60. In the process of adjusting the alignment inclinometer pipe by the rotary cylinder 60, the limiting abutting of the damping on the second one-way bearing 75 can be loosened, and the damping is preferably a bolt.
