Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Referring to fig. 1 to 3, according to a first aspect of the present invention, there is provided a top drive rotary angle measuring apparatus, the top drive rotary angle measuring apparatus includes a top drive body 100 and a rotary head 110 rotatable with respect to the top drive body 100, the top drive rotary angle measuring apparatus includes a distance measuring sensor 130 and a part to be measured 121, the distance measuring sensor 130 is configured to be disposed on one of the top drive body 100 and the rotary head 110, the part to be measured 121 is configured to be disposed on the other of the top drive body 100 and the rotary head 110, the distance measuring sensor 130 and the calibration member 120 may have two arrangements, the first arrangement being: the distance measuring sensor 130 is installed on the top drive body 100, the part to be measured 121 is disposed on the spin head 110, and the second: the distance measuring sensor 130 is installed on the spin head 110, the part to be measured 121 is disposed on the top drive body 100, a probe head of the distance measuring sensor 130 corresponds to the part to be measured 121, and when one of the distance measuring sensor 130 and the part to be measured 121 rotates with the spin head 110, a distance between the distance measuring sensor 130 and the part to be measured 121 continuously changes.
Before this, the correspondence relationship between the rotation angle of the rotary head 110 and the distance between the distance measuring sensor 130 and the part to be measured 121 may be calculated in advance, for example, the distance between the distance measuring sensor 130 and the part to be measured 121 is 1.0cm when the rotary head 110 is rotated by 10 ° with respect to the initial position, and the distance between the distance measuring sensor 130 and the part to be measured 121 is 1.2cm when the rotary head 110 is rotated by 20 ° with respect to the initial position, that is, the distance between the distance measuring sensor 130 and the part to be measured 121 corresponding to the rotation angle of the rotary head 110 is unique per a certain angle of rotation of the rotary head 110. Based on this, when the rotating head 110 rotates for the top drive body 100, the distance between the distance measuring sensor 130 and the part 121 to be measured can present continuous variation, and therefore the rotating angle of the rotating head 110 can be calculated according to the distance variation between the distance measuring sensor 130 and the part 121 to be measured, and therefore, the rotating angle of the rotating head 110 can be accurately measured, which is beneficial to improving the operation efficiency, reduces the use cost, does not need an operator to manually measure the angle of the rotating head 110, can avoid safety accidents, and is beneficial to improving the automation degree of the top drive operation. Moreover, since the distance measuring sensor 130 does not contact the part to be measured 121, the service life of the distance measuring sensor 130 can be greatly prolonged, and the effectiveness of the work flow is increased.
Further, when one of the ranging sensor 130 and the part to be measured 121 rotates with the rotary head 110, the distance between the ranging sensor 130 and the part to be measured 121 gradually increases or gradually decreases, in other words, when the rotation angle of the rotary head 110 gradually increases, the distance between the ranging sensor 130 and the part to be measured 121 may gradually increase or gradually decrease, and when the rotation angle of the rotary head 110 gradually decreases, the distance between the ranging sensor 130 and the part to be measured 121 may gradually decrease or gradually increase, and by gradually increasing or gradually decreasing the distance between the ranging sensor 130 and the part to be measured 121, a unique rotation angle value corresponding to the distance value may be acquired. It can be understood that, during the clockwise rotation of the spin head 110, if the distance between the distance measuring sensor 130 and the part 121 to be measured increases and then decreases, or decreases and then increases, similarly, during the counterclockwise rotation of the spin head 110, if the distance between the distance measuring sensor 130 and the part 121 to be measured increases and then decreases, or decreases and then increases, there may be two identical distance values, which may result in that the rotation angles corresponding to the two identical distance values cannot be accurately calculated, thereby affecting the measurement of the angle value of the spin head 110.
Optionally, the part to be measured 121 is an inclined arc-line structure, where the inclination refers to that the arc-line structure extends upward in a substantially curved manner with respect to the lower surface of the top drive body 100, so that when the rotating head 110 rotates relative to the top drive body 100, the distance between the distance measuring sensor 130 and the part to be measured 121 changes, thereby accurately measuring the rotating angle of the rotating head 110.
Alternatively, the part to be measured has a slope structure extending in a meandering manner, and the area to be measured of the part to be measured 121 can be increased by using the slope structure compared with a line structure, so that the distance measuring sensor 130 can always detect the part to be measured 121 during measurement, thereby ensuring the accuracy of measurement.
Further, the part to be measured 121 is configured as a linear structure or an arc-line structure extending around the circumference of one of the top drive body 100 or the rotary head 110, that is, the part to be measured 121 may be a linear structure or an arc-line structure, where the linear structure or the arc-line structure not only means that the part to be measured 121 is a linear structure, but also means that the calibration member 120 has an outer surface, and the part to be measured 121 in a linear structure is a part of the outer surface.
In some embodiments, in consideration of a limitation of an installation space between the top drive body 100 and the spin head 110, the part to be measured 141 is disposed on a circumferential surface of the top drive body 100 or the spin head 110, and the part to be measured 141 and the distance measuring sensor 130 may be conveniently installed due to an increased operation space.
In some embodiments, the part to be measured 121 may be a linear structure extending spirally upward or spirally downward around the rotation axis of the rotating head 110, for example, the part to be measured 121 may extend spirally like a spring shape.
Referring to fig. 2 and 3, in particular, the top drive rotation angle measuring device includes a calibration member 120, the calibration member 120 is a plate-shaped structure for being attached to one of the outer surface of the top drive body 100 and the outer surface of the rotary head 110, the part to be measured 121 is located at a lower edge or an upper edge of the plate-shaped structure, the part to be measured 121 is located at the lower edge of the plate-shaped structure when the calibration member 120 is located at the outer surface of the top drive body 100, and the part to be measured 121 is located at the upper edge of the plate-shaped structure when the calibration member 120 is located at the outer surface of the rotary head 110, so that an occupied space of the calibration member 120 extending radially to the top drive body 100 or the rotary head 110 can be reduced, and the structure of the top drive rotation angle measuring device is more compact.
The part to be measured 121 is used to be integrally formed on one of the top drive body 100 and the rotary head 110, that is, the part to be measured 121 may also be a part of the structure of the top drive body 100 and the rotary head 110, for example, a part of the entity is cut out of the outer surface of the top drive body 100 or the rotary head 110, so that a linear structure or an arc-shaped structure extending to the circumferential direction thereof, or a spiral structure may be formed on the outer surface of the top drive body 100 or the rotary head 110. Therefore, the calibration component 120 is directly machined by the top drive body 100 or the rotating head 110 without additionally manufacturing parts serving as the calibration component 120, which is beneficial to reducing the manufacturing cost.
In an alternative embodiment of the present invention, the distance measuring sensor 130 is at least one of an inductive displacement sensor, an ultrasonic distance measuring sensor 130, a laser sensor, an infrared distance measuring sensor 130, and a displacement sensor. When the distance measuring sensor 130 is an inductive displacement sensor, the calibration member 120 should be a metal structure so that the inductive displacement sensor can sense the calibration member 120, and in addition, the inductive displacement sensor can be used in a severe environment, for example, the inductive displacement sensor is not affected by wind, sand, rain, snow, and the like.
The top drive pivot angle measuring device further includes a controller (not shown) connected to the distance measuring sensor 130, and the controller may be of any suitable type, for example, the controller may be implemented as an ohron C200HX-CPU 44-E. The controller is used for converting the received electric signal into a distance value, and the controller can be a PLC. The controller and the ranging sensor 130 can be connected wirelessly, which can reduce interference to the wire due to movement of the mechanism compared to a wired connection.

According to a third aspect of the present invention, there is provided a top drive rotation angle measuring method applied to the above-mentioned top drive rotation angle measuring apparatus, the measuring method comprises that the part to be measured 121 comprises at least a first measuring point and a second measuring point, the first measuring point is defined to be close to the ranging sensor 130 relative to the second measuring point, the rotary head 110 is driven to rotate relative to the top drive body 100, when the rotary head 110 rotates from a first position corresponding to the first measuring point to a second position corresponding to the second measuring point, where the first position can be an initial position of the rotary head 110, a distance value between the ranging sensor 130 at the first position and the first measuring point and a distance value between the ranging sensor 130 at the second position and the second measuring point of the ranging sensor 130 are respectively recorded, and according to the distance value between the ranging sensor 130 and the first measuring point and the ranging sensor 130 at the second position of the ranging sensor 130, the distance value between the ranging sensor 130 and the first measuring point and the ranging sensor 130 at the second position are respectively recorded 130, and the second measuring point, thereby obtaining a rotation angle of the spin head 110.
