[0019] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0020] like Figure 1 and Figure 2 As shown, the wireless anti-lifting device of the well repair vehicle includes a receiving module S1 and a transmitting module S2.

[0021] The receiving module S1 includes a wireless receiver 1. A fuse 2 is provided upstream of the wireless receiver 1. The fuse 2 is connected to the vehicle power supply 7 of the well repair vehicle. An anti-lifting and breaking indicator light 3 is connected in series downstream of the wireless receiver 1. An electromagnetic reversing valve 4 is connected in series downstream of the anti-lifting and breaking indicator light 3. A combined operating handle 5 is provided downstream of the electromagnetic reversing valve 4.

[0022] It should be noted that one end of the combined operating handle 5 is connected to the electromagnetic reversing valve 4 , and the other end of the combined operating handle 5 is connected to the quick air release valve 12 . The quick air release valve 12 is connected to the main air source 10 .

[0023] In addition, the combined operating handle 5 is in an ON position or an OFF position. When the combined operating handle 5 is in the OFF position, the combined operating handle 5 touches the switch 9 and turns on the switch 9.

[0024] The transmitting module S2 includes a wireless transmitter 6 , which is connected to a dry battery 8 via a switch 9 , and the dry battery 8 provides power for the wireless transmitter 6 .

[0025] It should be noted that the voltage of the vehicle-mounted power supply 7 is 24V, and the dry battery 8 is a 9V laminated dry battery.

[0026] In addition, the switch 9 is a sheet-shaped enclosed switch.

[0027] In addition, the transmitting module S2 is enclosed in a plastic box for protection.

[0028] The working mode of the wireless anti-lifting and breaking device of the workover vehicle is described below.

[0029] When the combined operating handle 5 is in the OFF position, the semi-closed gate of the wellhead blowout preventer is in the closed state. At this time, the combined operating handle 5 touches the switch 9, and the switch 9 remains in the on state, the wireless transmitter 6 is energized, the wireless transmitter 6 transmits a signal, the wireless receiver 1 receives the signal, and the anti-lifting and breaking indicator light 3 is always on, reminding the driller to control the electromagnetic reversing valve 4 to switch, cut off the outlet pipeline of the combined operating handle 5, and make the winch clutch 11 unable to engage or disengage, thereby avoiding the oil pipe lifting operation from scratching the oil pipe coupling and the semi-closed gate of the hydraulic blowout preventer, and the only way is to lower the oil pipe.

[0030] When the combined operating handle 5 is in the ON position, the semi-closed gate of the wellhead blowout preventer is in the open state, the switch 9 is disconnected, the wireless transmitter 6 is powered off, the wireless receiver 1 receives no signal, the anti-lift-off indicator light 3 is off, the electromagnetic reversing valve 4 is controlled to return to its original position, the air outlet pipeline of the combined operating handle 5 is connected to the quick air release valve 12, and the air intake of the winch clutch 11 is restored to achieve the purpose of normal lifting and lowering of the pipe string.

[0031] After the wireless anti-lifting device of the workover vehicle is installed, workers no longer need to go to the wellhead to confirm the position of the half-closed gate of the wellhead blowout preventer. If the gate is closed, there is no way to lift the pipe column, thus ensuring safe operation.

[0032] The wireless anti-lift-off device for the workover vehicle has a simple structure and is easy to install. It does not require any changes to the original electrical appliances of the workover vehicle. The device is sensitive and reliable. The control distance of the wireless device is within 300 meters. It is highly practical and is suitable for use with any workover vehicle and a hydraulic blowout preventer group with a remote control cabinet.

[0033] Without limitation to this, any changes or substitutions that are not conceived through creative work should be included in the protection scope of the present utility model. Therefore, the protection scope of the present utility model should be based on the protection scope defined in the claims.
