[0002] At present, the brake system of oil drilling winch generally uses valves to trigger gas signals to drive liquid to perform braking actions, or transmits electrical signals to PLC through equipment and then performs braking actions through electricity → gas → liquid or electricity → liquid. Due to the large number of components in the system, the long transmission path and the redundant protection of the system design, emergency braking will be triggered when a device in the system fails or the signal is lost. This single-mode braking, high-frequency emergency braking, unnecessary emergency braking, etc., affect equipment performance and drilling efficiency. Summary of the invention

[0005] The present invention is also characterized in that:

[0006] The winch drum is respectively connected with a working clamp and a safety clamp, and both the working clamp and the safety clamp are connected to the control system through pipelines and cables.

[0007] The control system is also connected to an audible and visual alarm mechanism via a cable.

[0008] Another technical solution adopted by the present invention is a control method of a winch brake protection control system, which is specifically implemented according to the following steps:

[0009] Step 1: Input a brake signal to the control system and classify the brake signal;

[0010] Step 2: According to the classified brake signal, the control system performs a brake operation.

[0011] Another technical solution of the present invention is also characterized in that:

[0012] Braking signals are divided into emergency braking, soft braking, warning delayed braking and alarm.

[0013] When the brake signal is an emergency brake, the control system performs emergency brake on the working clamp and the safety clamp through the disc brake system; when the brake signal is a flexible brake, the control system uses the energy-consuming brake system to drive the motor to decelerate the winch drum, and at the same time the control system performs inching brake on the working clamp and the safety clamp through the disc brake system; when the brake signal is an alarm delayed brake, the control system first controls the sound and light alarm mechanism to alarm, and after the delay the energy-consuming brake system causes the motor to drive the winch drum to decelerate, and at the same time the disc brake system performs inching brake on the working clamp and the safety clamp; when the brake signal is an alarm, the control system controls the sound and light alarm mechanism to alarm.

[0016] 2) All brake feedback signals are divided into four categories according to the degree of danger and urgency. Each category corresponds to a braking mode among emergency braking, soft braking, delayed braking and alarm, which can reduce the frequency of impact emergency braking.

[0021] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] The winch brake protection control system of the present invention is as follows: Figure 1As shown, the control system 2 includes a control system 2, which is respectively connected to a disc brake system 4 and an energy-consuming brake system 3 through pipelines and cables, and the disc brake system 4 is connected to a winch drum 7 through pipelines. The winch drum 7 is equipped with a reduction box 9, and the input shaft of the reduction box 9 is connected to a motor 8, and the motor 8 is connected to the energy-consuming brake system 3 through a cable. The brake signal 1 is converted into an electrical signal and fed back to the control system 2. The control system 2 implements brake protection for the winch through the energy-consuming brake system 3 and the disc brake system 4. The brake signal 1 can be an anti-collision air signal, a handle brake signal, an emergency stop button signal, an electrical signal of a sensor and an electrical component, and other auxiliary signals such as oil pressure and wind pressure.

[0023] Example 1

[0024] The winch brake protection control system includes a control system 2, which is respectively connected to a disc brake system 4 and an energy-consuming brake system 3 through pipelines and cables. The disc brake system 4 is connected to a winch drum 7 through pipelines. The winch drum 7 is provided with a reduction box 9. The input shaft of the reduction box 9 is connected to a motor 8, and the motor 8 is connected to the energy-consuming brake system 3 through a cable.

[0025] The winch drum 7 is respectively connected with a working clamp 61 and a safety clamp 62 , and both the working clamp 61 and the safety clamp 62 are connected to the control system 2 through pipelines.

[0026] The control system 2 is also connected to an audible and visual alarm mechanism 5 via a cable.

[0027] Example 2

[0028] When the driller presses the emergency stop button on the operation panel, the PLC control system 2 immediately controls the disc brake system 4 to perform emergency braking on the working clamp 61 and the safety clamp 62 at the same time, and the motor 8 stops running, and the sound and light alarm mechanism 5 alarms.

[0029] Example 3

[0030] When the air source pressure drops below the set value, the brake signal 1 (low air pressure) is fed back to the control system 2. The control system 2 first controls the sound and light alarm 5 to alarm, reminding the driller to pay attention to the abnormal situation. At the same time, the energy-consuming braking system 3 causes the motor 8 to reversely drag the winch drum 7 to slow down. After the speed is reduced, the disc brake system 4 is controlled to brake the winch drum 7, and the motor 8 stops running.

[0031] Control method of winch brake protection control system, such as Figure 2 As shown, the specific implementation steps are as follows:

[0032] Step 1, inputting a brake signal 1 to a control system 2, and classifying the brake signal 1;

[0033] Step 2: According to the classified brake signal 1, the control system 2 performs a brake operation.

[0034] Braking signal 1 is divided into emergency braking, soft braking, warning delay braking and alarm.

[0035] When the brake signal 1 is an emergency brake, the control system 2 performs emergency brake on the working clamp 61 and the safety clamp 62 through the disc brake system 4;

[0036] When the brake signal 1 is a flexible brake, the control system 2 causes the motor 8 to drive the winch drum 7 to decelerate through the energy-consuming brake system 3. At the same time, the control system 2 performs a jog brake on the working clamp 61 and the safety clamp 62 through the disc brake system 4. After the speed of the winch drum 7 drops to 0, the disc brake system 4 is completely braked, and the winch motor 8 is in a suspended state;

[0037] When the brake signal 1 is an alarm delay brake, the control system 2 first controls the sound and light alarm mechanism 5 to alarm, and after a delay (the delay time can be set to 5s to 15s according to actual needs), the energy-consuming brake system 3 causes the motor 8 to drive the winch drum 7 to decelerate, and at the same time, the disc brake system 4 performs a jog brake on the working clamp 61 and the safety clamp 62. After the speed of the winch drum 7 drops to 0, the disc brake system 4 is completely braked and the motor 8 stops;

[0038] When the brake signal 1 is an alarm, the control system 2 controls the sound and light alarm mechanism 5 to alarm, and only the alarm prompt is executed at this time.
