[0017] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0018] Combine Figure 1 、 2As shown, this embodiment provides a remote power tong control system, comprising: a power tong body, a control box 1, and a remote control 2. The control box 1, mounted on the power tong body, is the core component of the entire control system and includes a housing 11, a circuit board, an operating knob, and a mode switch knob 14. The housing 11 provides support and protection for the circuit board, operating knob, and mode switch knob 14. The circuit board is housed within the housing 11 and includes a control module 121 and a remote control module 122 connected to the control module 121. The control end of the control module 121 is connected to the power tong body and is responsible for processing control signals and transmitting control commands to the power tong body to execute corresponding actions. The remote control module 122 is wirelessly connected to the remote control 2, receiving wireless signals from the remote control 2, converting them into control signals recognizable by the control module 121, and transmitting them to the control module 121. The operating knob and mode switch knob 14 are respectively mounted on the housing 11 and connected to the control module 121. The mode switch knob 14 is used to switch between local and remote control modes. When the mode switch knob 14 is in the local control mode, the control signal can be directly sent to the power clamp body to perform corresponding actions, such as clamping, rotation, etc. by rotating the operating knob; when the mode switch knob 14 is in the remote control mode, a wireless signal can be sent to the remote control module 122 of the control box 1 through the remote controller 2. The remote control module 122 receives and analyzes the wireless signal, and then sends it to the control module 121. The control module 121 controls the power clamp body to perform corresponding actions.

[0019] Specifically, the operating knobs include a high- and low-speed switching knob 131, a make-up and break-out knob 132, a forward and reverse knob 133, and a left and right turn knob 134. The high- and low-speed switching knob 131 is used to achieve different operating modes and effects to meet the different needs of well repair, drilling, and other operations. The high-speed mode focuses on improving rotation speed and operating efficiency and is suitable for fast rotation and connection; the low-speed mode focuses on torque output and connection stability and is suitable for operating scenarios requiring greater power or higher reliability. The make-up and break-out knob 132 is used to connect or disconnect the drill pipe or tubing section. The forward and reverse knob 133 is used to adjust the front and rear position of the drill pipe or tubing section. The left and right turn knob 134 is used to rotate the drill pipe or tubing section.

[0020] Furthermore, the remote power tong control system also includes solenoid valves. The control end of the control module 121 controls the power tong body to perform corresponding actions through the solenoid valves. Specifically, the solenoid valves include a pneumatic solenoid valve 31 and a hydraulic solenoid valve 32. The pneumatic solenoid valve 31 has a self-locking mechanism. That is, when the operating knob or remote control 2 is long pressed, the pneumatic solenoid valve 31 will remain open and self-lock until it receives a closing signal; a short press will cause the pneumatic solenoid valve 31 to be de-energized and closed. This design allows the user to control the opening and closing time of the pneumatic control system as needed. Preferably, the control end of the control module 121 controls the power tong body to perform high-speed and / or low-speed switching, make-up and / or break-out actions, and forward and / or reverse actions through the pneumatic solenoid valve 31; the control end of the control module 121 controls the power tong body to perform left and / or right turns through the hydraulic solenoid valve 32. Thus, this embodiment utilizes both the pneumatic solenoid valve 31 and the hydraulic solenoid valve 32 to fully utilize their advantages and achieve comprehensive control of the power tong body. This not only improves the flexibility and adaptability of the control system but also ensures efficient and accurate operation under various working conditions.

[0021] Furthermore, remote control 2 is equipped with an emergency stop button and a reset start button. The emergency stop button immediately stops all operations to ensure safety. After an emergency stop, the reset start button must be pressed to release the emergency stop and restore the control system to an operational state. The provision of the emergency stop button and reset start button is crucial to ensuring system safety and operational flexibility.

[0022] Furthermore, a solid-state relay 123 is provided on the circuit board, and the control terminal of the control module 121 is connected to the solenoid valve via the solid-state relay 123. The provision of the solid-state relay helps protect the control circuit and the solenoid valve from high voltage and high current, thereby improving the safety and stability of the system.

[0023] In summary, this embodiment of the remote power tong control system ensures safe, efficient, and precise operation of the power tong through sophisticated control logic and multiple safety mechanisms. Whether in local or remote control mode, users can select the appropriate operating mode based on their needs, and precisely control the rotation and lifting of the power tong through inching mode.

[0024] The above descriptions are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these all fall within the scope of protection of the present invention.
