[0002] The top drive is a necessary equipment for drilling deep wells, complex wells, and difficult wells in oil drilling operations. The top drive arm is operated by the driller in the driller's room. The driller is inevitably negligent during operation, which may cause the top drive arm to collide with the second-floor platform finger beam from directly above or directly below, causing equipment damage, delays in working hours, and even machine destruction and death. Therefore, ensuring safety during oil drilling operations, reducing accident risks, and protecting the lives and property of personnel are the key points of work. However, it is difficult to ensure that there will be no mistakes relying solely on the operation and awareness of personnel, so mechanical equipment is needed to prevent the harm caused by misoperation.

When dealing with sudden collisions, it is limited by the delay effect of the mechanical transmission components, and the brake response is slow. In addition, high-speed emergency braking is prone to occur during the braking process. The excessive impact load generated by the emergency braking will cause damage to the derrick and other equipment. Summary of the invention

[0026] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0027] Example 1

[0028] like Figure 1 As shown, this embodiment includes a first anti-collision line 1 and a second anti-collision line 2 installed above the second-floor platform finger beam 9, and a third anti-collision line 3 and a fourth anti-collision line 4 installed below the second-floor platform finger beam 9. It also includes a main brake system, an auxiliary brake system, a main brake switch that controls the main brake system, and an auxiliary brake switch that controls the auxiliary brake system. The installation height of the first anti-collision line 1 is higher than the second anti-collision line 2, and the installation height of the fourth anti-collision line 4 is lower than the third anti-collision line 3.

[0029] Two brackets are provided above and below the second-floor platform finger beam 9, which are installed at both ends of the second-floor platform finger beam 9 in the length direction and used to support the anti-collision line. For the convenience of description, in this embodiment, the bracket on the upper left side of the second-floor platform finger beam 9 is named as the upper left bracket 5, the bracket on the upper right side of the second-floor platform finger beam 9 is named as the upper right bracket 6, the bracket on the lower left side of the second-floor platform finger beam 9 is named as the lower left bracket 7, and the bracket on the lower right side of the second-floor platform finger beam 9 is named as the lower right bracket 8. One end of the first anti-collision line 1 is connected to the auxiliary brake switch, and the other end passes through the upper right bracket 6 and is fixed on the upper left bracket 5; one end of the second anti-collision line 2 is connected to the main brake switch, and the other end passes through the upper left bracket 5 and is fixed on the upper right bracket 6; one end of the third anti-collision line 3 is connected to the main brake switch, and the other end passes through the lower left bracket 7 and is fixed on the lower right bracket 8; one end of the fourth anti-collision line 4 is connected to the auxiliary brake switch, and the other end passes through the lower right bracket 8 and is fixed on the lower left bracket 7. The anti-collision line is an elastic line that can undergo deformation and rebound, and is installed on the bracket in a straight state.

[0030] The output end of the main brake switch is connected to the input end of the main brake system, and the main brake switch controls the opening and closing of the main brake system. The main brake system includes a hydraulic disc brake and an air source that provides braking force to the hydraulic disc brake.

[0031] The output end of the auxiliary brake switch is connected to the input end of the auxiliary brake system, and the auxiliary brake switch controls the opening and closing of the auxiliary brake system. The auxiliary brake system includes an electromagnetic eddy current brake, a first power supply for supplying power to the electromagnetic eddy current brake, a signal encoder, and a second power supply for supplying power to the signal encoder. The output end of the signal encoder is connected to the input end of the electromagnetic eddy current brake, and the signal encoder is used to measure the speed of the electromagnetic eddy current brake shaft, compare the measured shaft speed with the set speed, generate a control signal and input the control signal to the electromagnetic eddy current brake, thereby adjusting the magnitude of the electromagnetic eddy current brake braking torque.

[0032] When the driller makes a mistake in operation and the top drive arm approaches from above or below the second-floor platform finger beam 9, the straightened first anti-collision line 1 or the fourth anti-collision line 4 will be pressed to deformation first, and the auxiliary brake switch will be turned on under the elastic force of the deformation of the first anti-collision line 1 or the fourth anti-collision line 4, thereby turning on the auxiliary brake system. The electromagnetic eddy current brake connected to the first power supply and the signal encoder connected to the second power supply start to work. With the assistance of the signal encoder, the electromagnetic eddy current brake continuously adjusts the braking torque of the brake, brakes the top drive arm smoothly and gently, and reduces the speed of the top drive arm.

[0033] If the top drive arm does not stop under the action of electromagnetic eddy current brake and continues to move, it will continue to deform the second anti-collision line 2 downward after compressing and deforming the first anti-collision line 1, or continue to deform the third anti-collision line 3 upward after compressing and deforming the fourth anti-collision line 4. At this time, the main brake switch is turned on by the elastic force of the deformation of the second anti-collision line 2 or the third anti-collision line 3, and the main brake system is started. The hydraulic disc brake provides braking force from the air source to completely stop the top drive arm to avoid safety accidents.

[0034] In this embodiment, the first power supply and the second power supply use 220V power supply and 12V power supply, which can be adjusted according to actual conditions as long as the electromagnetic eddy current brake and the signal encoder can be started.

[0035] It should be noted that the description of left and right in this embodiment is only used to explain the positional relationship of the component structures in this embodiment.

[0036] It should be noted that, in the present embodiment, the first anti-collision line 1 and the second anti-collision line 2 are respectively fixed on the upper left bracket 5 and the upper right bracket 6, and the third anti-collision line 3 and the fourth anti-collision line 4 are respectively fixed on the lower right bracket 8 and the lower left bracket 7. They can be adjusted according to actual conditions, as long as the first anti-collision line 1 and the second anti-collision line 2 are fixed to any one of the upper left bracket 5 or the upper right bracket 6, and the third anti-collision line 3 and the fourth anti-collision line 4 are fixed to any one of the lower left bracket 7 or the lower right bracket 8. The premise is to ensure that the projection of each anti-collision line in the horizontal plane intersects with the two ends of the projection of the second-floor platform finger beam 9 in the horizontal plane.
