Detailed Description

The invention will be further described with reference to the drawings and specific embodiments, illustrative embodiments and description of which are provided herein to explain the invention, but not as a limitation thereof.

As shown in fig. 1: the utility model discloses a laser sensor, state display function module, PLC system and actuating mechanism, laser sensor installs in the side position of last drilling rod and lower drilling rod junction, just laser sensor's scanning end is just right go up the drilling rod with the junction of drilling rod down, laser sensor's image signal output with state display function module's signal input part connects, laser sensor's data output end with the data input part of PLC system connects, the control signal output part of PLC system with actuating mechanism connects, actuating mechanism is used for control go up the drilling rod with the mechanism that the drilling rod is connected down.

Further, the laser sensor is a Poscon 3D laser scanning sensor. The PosCon 3D photoelectric edge detection sensor has the strongest function in the similar products, the product has reliable performance, and can be used in the application field which only has a complex laser measurement system to be competent in the past, in addition, the PosCon 3D operation and installation are very convenient, the sensor becomes a universal solution for detecting the edge position and the object or gap width due to the versatility, and the product does not need to use an independent reflective tape. The movement of the object within the measuring area towards or away from the sensor does not affect the measurement result. The PosCon 3D can reliably identify any object without being influenced by the color and the surface condition of the object, and the design can ensure that the optical axis of the sensor is directly aligned with the mounting hole, so that the system integration can be easily completed in the early planning stage by utilizing the CAD data of the sensor.

The PosCon 3D has the highest application flexibility and is simple to operate, and the PosCon 3D can be installed only by aiming at an object and selecting a language on a touch screen; even if the mounting position is not vertical and the offset angle does not exceed 30 °, the edge position can be reliably detected. The sensor can identify the object width in a fraction of a second with an accuracy of up to 2/10 mm, regardless of where the object is within the measurement area.

The PosCon 3D may also identify the center of the object. Once the position of the object deviates from the tolerance range, the sensor triggers the switching value output and the communication connection is used for calculating and judging the output through the PLC system. The edge detection sensor is particularly suitable for gap control. The PosCon 3D can accurately measure the gap between the two objects, and real-time gap data between the two objects can be detected and controlled in real time through the control system so as to meet the control process requirements.

As an improvement, the PLC system is also connected with a fault alarm.

Example (b):

as shown in fig. 2-4, in the figure, a 1-upper drill rod, a 2-lower drill rod and a 3-laser sensor adopt a laser scanning edge sensor to control a top drive frequency converter.

Example I, controlling the Up-Down moving distance of the Top drive Elevator

The traditional drill rod screwing-in process is that the driller manually controls the top drive hook to move up and down through the handle to control the distance between the two end faces of the lower drill rod of the upper drill rod box, the control mode is difficult to be controlled manually by the driller, the action time is relatively long, the anti-collision protection of the male and female drill rod buttons is not facilitated, and the laser scanning detection device can fully exert the performance of the device under the working condition.

The advantages are that:

under the condition that the height of a drill rod on the bottom surface is kept unchanged, when the drill rod on the upper portion enters a detection area, the laser scanning detection device detects that the drill rod enters, an alarm signal is sent out through the PLC system, the top drive driving device is controlled to slow down, the interval data of the upper drill rod and the lower drill rod to be detected is transmitted to the PLC system in real time, the PLC system and the top drive form a closed-loop control system through calibration calculation, and the top drive elevator is controlled to automatically adjust the running speed and accurately position and stop according to the detected feedback data.

If the upper and lower drill rods are not on the same vertical axis and fall to enter a laser scanning position through the top drive, the fact that the drill rod is not detected indicates that the upper drill rod deviates from the vertical axis, under the condition, the PLC system can immediately send a command that the top drive elevator stops falling, the situation that the screw thread of the upper drill rod collides with the end face of the lower drill rod to damage a drill rod interface due to the fact that the upper drill rod continues to fall is avoided, meanwhile, alarm information is sent to a driller, and the elevator is timely adjusted to enable the drill rods to be on the same vertical axis.

In the above-mentioned detection device, the laser signal detection is the key of this control system, it not only requires to be able to detect the spacing data and feedback information accurately and in real time, but also requires to be able to transmit to the PLC system and the top drive control adjustment device quickly and reliably for fault handling and status display, and it also becomes a key link of this system to connect with the PLC system and the top drive control adjustment device.

The working process of the utility model is as follows:

1. the top drive elevator (i.e., actuator) holds the lower position of the wellhead floor surface of the lower drill pipe floor and secures the drill pipe by the drill chuck.

2. The top drive elevator (i.e., actuator) moves the upper drill pipe down into the detection range of the laser sensor.

3. When the upper end face of the upper drill rod screw thread enters a detection range, the detection distance is calculated through a PLC system to control the top drive driving device to decelerate, and the moving speed is automatically adjusted by tracking detection data in real time.

4. And when the distance between the upper drill rod and the lower drill rod is detected to be within a set range, the buckling is successful.

5. If the top drive descends to the set detection effective range and no drill rod is detected, the drill rod deviates from the vertical axis, the top drive stops descending, and after the problem is processed, the 3-4 steps of actions are repeated.

The technical scheme of the utility model is not limited to the restriction of above-mentioned specific embodiment, all according to the utility model discloses a technical scheme makes technical deformation, all falls into within the protection scope of the utility model.
