The interactive display module 140 is used to display the state parameters of the workover rig collected by the sensor module 120 and form a human-computer interaction interface with the control module 110 for reading and writing data, adjusting parameters and diagnosing faults. The execution module 150 is electrically connected to the control module 110. The execution module 110 includes the engine 211, the torque converter 212 and the clutch 213 of the workover rig chassis 210, and also includes the hydraulic disc brake 220 of the workover rig.

[0026] In this solution, the interactive display module 140 uses a touch screen to display the values ​​of each signal collected by the sensor module 120 in real time. The driller monitors the operation of the well repair rig according to the size of each value, and the interactive display module 140 and the control module 110 form a human-computer interaction interface, which can adjust the operating parameters of the well repair rig and timely judge the operating failure of the well repair rig through the interactive display module 140, which greatly reduces the labor intensity of the driller and improves the automation level of the well repair rig, realizes real-time monitoring of the operating parameters of the well repair rig operation site, and can effectively reduce equipment and personal accidents during the operation of the well repair rig.

[0027] The communication module 130 is used to realize data transmission between various units in the electronic control system. In the actual working process, the communication module can be selected according to the actual situation on site. It can be one or more of hard-wired connection, data transmission based on CAN bus protocol, 4G transmission or wireless network transmission.

[0028] As a specific solution of the above technical solution, the sensor module 120 includes: an engine monitoring system 121 arranged on the chassis of the well repair machine, the engine monitoring system 121 is used to monitor the operating status of the engine 211 and feed back the engine status to the control module 110 through the communication module 130; the model of the engine monitoring system 121 in the present application document is SPC3-M001, and the engine monitoring system 121 is connected to the control module 110 through a CAN bus transmission interface, and its function is to monitor the conventional parameters and post-processing parameters of the engine 211 in the working and walking states, read the fault code parameters, and provide the control module 110 with summary and display on the interactive display module 140, and can execute the control instructions issued by the control module 110 to the engine 211 when the engine 211 is in the working state.

[0029] It also includes a torque converter monitoring system 122 arranged on the chassis torque converter 212, which is used to monitor the status of the torque converter 212 and send the monitoring results to the control module 110 through the communication module 130; the function of the torque converter monitoring system 122 is to monitor the normal parameters and gear position of the torque converter 212 for the control module 110 to summarize and display, and execute the control instructions issued by the control module 110 to the torque converter 212 in the operating state.

[0030] The hydraulic disc brake monitoring system 123 on the hydraulic disc brake 220 is used to monitor the operating status of the hydraulic disc brake 220 and feed back the monitoring results to the control module 110 through the communication module 130; the hydraulic disc brake monitoring system 123 includes a first pressure sensor 1231, a second pressure sensor 1232 and a third pressure sensor 1233, the first pressure sensor 1231 is arranged on the working clamp oil supply pipeline 221 of the hydraulic disc brake 220, and the working clamp oil supply pipeline 221 is also provided with a proportional pressure reducing valve 222, the second pressure sensor 1232 is arranged on the safety clamp oil supply pipeline 223 of the hydraulic disc brake 220, and the safety clamp oil supply pipeline 223 is also provided with a first solenoid valve 224, and the third pressure sensor 1233 is arranged on the return oil pipeline 225 of the hydraulic disc brake 220. The first pressure sensor 1231 , the proportional pressure reducing valve 222 , the second pressure sensor 1232 , the first solenoid valve 224 and the third pressure sensor 1233 are all connected to the control module 110 via the communication module 130 .

[0031] When the first pressure sensor 1231 detects that the pressure value in the working clamp oil supply pipeline 221 is abnormal, the proportional pressure reducing valve 222 and the engine 211 speed can be adjusted through the control module 110, thereby adjusting the rising speed of the travel carriage of the workover rig.

[0032] When the second pressure sensor 1232 detects that the pressure value in the safety clamp oil supply pipeline 223 is abnormal, the control module 110 can stop the engine 211 on the one hand, and cut off the oil supply from the working clamp oil supply pipeline 221 and the safety clamp oil supply pipeline 223 to the working clamp 226 and the safety clamp 227 through the proportional pressure reducing valve 222 and the first solenoid valve 224 on the other hand, so that the safety clamp 226 and the working clamp 227 lock the brake disc 228 at the same time, ensuring the safety of the well repair rig operation.

[0033] A drum sensor 124 is provided on the drum of the well repair machine; the drum sensor 124 is installed at the shaft head position of the drum 230, synchronously obtains the rotation state of the drum 230, and sends a signal to the control module 110 through the communication module 130, thereby determining the height, speed, running direction, etc. of the traveling carriage.

[0034] The hook load sensor 125 provided on the hook 240 of the workover rig is used to monitor the hook load on the hook 240; the hook load sensor 125 is installed at the three-way interface of the hydraulic pipeline at the front end of the mechanical weight indicator, converts the oil pressure signal into an electrical signal and sends it to the control module 110. The hook load is an important operation parameter and is displayed on the interactive display module 140 to guide the driller's operation.

[0035] The wind speed sensor 126 disposed on the derrick 250 of the workover rig is used to monitor the wind speed at the derrick 250. In this application document, the wind speed sensor 126 uses a three-cup wind speed measuring instrument to convert the measured wind speed into an electrical signal and send it to the control module 110, thereby calculating the real-time wind level.

[0036] Preferably, the control module 110 also includes a vehicle controller 112, an expansion module 113 and a storage module 114, the vehicle controller 112 is electrically connected to the PLC 111; the expansion module 113 is set on the PLC via an O / I interface set on the PLC 111; the storage module 114 is electrically connected to the PLC 111, and the storage module 114 is provided with threshold values ​​of various parameters in the sensor module; the PLC 111 can compare the state parameters of the well repair machine collected by the sensor module 120 with the threshold values ​​of various parameters in the storage module 114, and issue a control instruction 150 to the execution module.

[0037] An electric control handle 160 is also provided in the driller's room, and the electric control handle 160 is electrically connected to the control module 110. The control module 110 can issue corresponding instructions to the execution module 110 according to the pushing direction and pushing angle of the electric control handle 160. An alarm system 170 is also provided in the driller's room, and the alarm system 170 is electrically connected to the control module 110. When the state parameter of the workover machine collected by the sensor module 120 exceeds the storage threshold in the storage module, the alarm system issues an alarm to remind the driller to pay attention.

[0038] In the above scheme, the control module 110 combines and calculates the real-time operating parameters of each sensor and monitoring system in the sensor module 120 and the action instructions applied by the driller to the electric control handle 160, and obtains the optimal engine throttle opening, engine speed, torque converter gear, drum clutch state, hydraulic disc brake working clamp opening and safety clamp state according to the built-in information such as the engine 211 curve and the torque converter 212 gear ratio. The driller only needs to push this electric control handle forward and backward to control the travel block running height, speed, brake, parking, reversing, etc. The control module 110 automatically outputs control instructions according to the driller's instructions (forward and backward push and pull direction, amplitude), current travel block height, speed, hook load and other parameters and engine curves, torque converter gear ratios, etc., and matches the appropriate engine speed, torque converter gear, clutch opening and closing, brake torque of the brake working clamp, etc., and outputs them to each actuator respectively, and cooperates with each other to complete the operation.

[0039] For example, in the process of lifting the tubing string, the driller starts to push the electric control handle 160 forward from the middle position. At this time, the control module 110 calculates the appropriate engine throttle, engine speed, torque converter gear according to the parameters such as the height, speed, hook load, etc. of the traveling carriage collected by the sensor module 120, controls the drum clutch to engage, outputs a speed command to the engine 211, outputs a gear command to the torque converter 212, outputs a release parking command to the hydraulic disc brake 220, and outputs a working clamp 226 opening command to open the working clamp 226, and the traveling carriage starts to rise; the driller continues to push the electric control handle 160 forward, and the intention at this time is to accelerate the lifting of the traveling carriage. The control module 110 gives the corresponding engine throttle, engine speed, and torque converter gear according to the amplitude of the electric control handle 160 being pushed forward until the traveling carriage is lifted to the required height. The driller pulls the electric control handle 160 back to the middle position, and the system changes the engine throttle, engine speed, and torque converter gear position, controls the working clamp 226 to brake evenly, and slows down the traveling carriage until the electric control handle 160 is completely pulled back to the middle position, the engine throttle and drum clutch are disconnected, the working clamp 226 and the safety clamp 227 are closed, and the traveling carriage stops and parks. The driller pulls the electric control handle 160 backward from the middle position. At this time, the control module 160 first determines whether to engage the reverse gear according to the hook load. If the hook load is too small to drag the traveling carriage down, the reverse gear reversing drum 230 is used to make the traveling carriage fall. On the contrary, if the hook load is large enough to drag the traveling block down by its own weight, the clutch is disengaged. At this time, the electric control handle 160 controls the braking force of the working clamp 226. The system will automatically control the lowering speed of the traveling block within a safe range according to the height, and slowly drop to the wellhead until the traveling block stops completely, the working clamp 226 and the safety clamp 227 are closed, and the traveling block stops and parks.

[0040] Since the control module 110 is provided with a storage module 114, it has an automatic memory function. It only needs to set the height, speed, oil pressure, inclination angle, wind speed and wind level and other related limiting parameters once, and there is no need to reset them after power failure.

[0041] Another technical solution also includes a mode switching module 180, which is electrically connected to the control module 110. The mode switching module 180 includes an automatic mode and a manual mode, and the corresponding storage module 114 stores the thresholds of the parameters in each sensor module in the automatic mode and the manual mode. If operations such as threading a wire rope and unblocking a card are required, the mode switching module 180 can be switched to a manual mode, allowing the traveling carriage to operate at an over-height, over-speed, and over-load within a certain degree and time.

[0042] As an optional solution of the technical solution of the present invention, it also includes a first brake module 190 arranged in the driller's room, the first brake module 190 is electrically connected to the control module 110, and the first brake module 190 can brake the execution module 150 through the control module 110. In actual use, the first brake module 190 can be connected to a red mushroom head button. In an emergency, when the driller presses this button, the corresponding solenoid valve is actuated to cut off the engine throttle and the drum clutch; the hydraulic disc brake working clamp and the safety clamp work at the same time, and the drum stops rotating immediately.

[0043] In another embodiment of the present application document, a user terminal 300 is further included. The user terminal 300 is connected to the control module 100 via the communication module 130. The user terminal 300 can display the status parameters of the well repair machine collected by the sensor module 120. A second braking module 310 is also provided on the user terminal 300. The second braking module 310 can brake the execution module through the control module 110. In the case that the on-site driller fails to control in time, the user terminal 300 can also activate the corresponding solenoid valve to cut off the engine throttle and the drum clutch. The hydraulic disc brake working clamp and the safety clamp work at the same time, and the drum 230 stops rotating immediately.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.
