The secondary hoist in the mine hoist system is responsible for the transportation of personnel going down the well. At present, the vice lifting machine adopts friction formula lifting machine usually, and it can rely on the frictional force between haulage rope and the leading wheel and the gravity difference between the promotion container at haulage rope both ends to promote the container for if vice lifting machine breaks down at transportation personnel's process, then vice lifting machine chance stop operation immediately, will lead to personnel that the vice lifting machine carried to be stranded in the mine for a long time, and the potential safety hazard is big.
Based on this, in order to reduce the trapped time of the personnel carried when the auxiliary hoist is in failure, the embodiment of the application provides a control method of a hoisting system.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a lifting system according to an embodiment of the present disclosure. The lifting system 100 comprises a first lifting vessel 110, a second lifting vessel 120 and a control device 130, wherein the first lifting vessel 110 and the second lifting vessel 120 are connected to the control device 130 for performing the steps in the subsequent method embodiment.
Specifically, the lifting system further comprises a traction rope, a guide wheel, a disc brake and the like. Wherein, the both ends of haulage rope are connected first promotion container and second promotion container respectively. The disc brake is used for driving the traction rope to move on the guide wheel. Specifically, the disc brake includes a brake disc, an oil chamber, and a brake shoe. Wherein, the oil cavity is connected with the brake shoe; the disc brake pushes the brake shoe to generate pressure on the brake disc by adjusting the oil quantity in the oil cavity; the brake disc is used for driving the haulage rope according to pressure to make the haulage rope move on the leading wheel, and then drive the first promotion container and the second promotion container lift at haulage rope both ends.
Referring to fig. 2, fig. 2 is a flowchart illustrating an implementation of a control method for lifting a container according to an embodiment of the present application, where the method includes the following steps:
s201, obtaining operation parameters of the lifting system during operation, wherein the operation parameters comprise the current moving speed of the traction rope and the working temperature of the disc brake.
In application, the above-mentioned operation parameters include not only the current moving speed of the traction rope and the working temperature of the disc brake, but also the weight of the first lifting container and the weight of the second lifting container, which is not limited thereto.
Wherein, because of the both ends of haulage rope are connected first promotion container and second promotion container respectively usually, consequently, above-mentioned current translation rate can gather through the tacho sensor who sets up in first promotion container and/or second promotion container, and then acquire from the test sensor. In another embodiment the current displacement speed of the traction rope is also related to the rotational speed of the guide pulley, and thus the current displacement speed can also be determined by monitoring the rotational speed of the guide pulley. In this embodiment, the manner of obtaining the current moving speed when the hoisting system operates is not limited.
The working temperature of the disc brake can be measured by a temperature sensor and then acquired by the control device, which is not limited.
S202, determining the working state of the lifting system according to the operation parameters.
In application, the working states are divided into normal states and abnormal states. Specifically, for the current moving speed and the working temperature in the operation parameters, if the current moving speed is greater than a preset normal speed and/or the working temperature is greater than a preset normal working temperature, determining that the lifting system is in an abnormal state; and if the current moving speed is less than or equal to the preset normal speed and the working temperature is less than or equal to the normal working temperature, determining that the lifting system is in a normal state.
In application, the preset normal speed and the preset normal working temperature can be set by the operation of workers, and the setting is not limited. Illustratively, the preset normal speed may be 1m/s.
It is to be added that the control device should control the disc brake to stop driving the traction ropes in order to ensure the safety of the passengers when it is determined that the hoisting system is in an abnormal state. I.e. the hoisting system stops running.
In another embodiment, when the operation parameter is the weight of the first lifting container or the weight of the second lifting container, if the weight of the first lifting container or the weight of the second lifting container exceeds a preset maximum bearing weight, it should be determined that the lifting system is in an abnormal state. In this embodiment, the manner of determining the operating state of the lift system based on the operating parameters is not limited.
S203, if the lifting system is determined to be in an abnormal state, acquiring the current position of the target lifting container; the target lifting container is a lifting container with a target object loaded in the first lifting container and the second lifting container.
In the application, it has been described above that the disc brake is controlled to stop driving the traction rope when the hoisting system is in an abnormal state, and at this time, the first hoisting container and the second hoisting container located at both ends of the traction rope are also stopped. Thereafter, the control device may acquire the current position of the target hoist container at the current time.
It should be noted that when it is determined that the hoist system is in an abnormal state and the disc brake is controlled to stop driving the traction ropes, the traction ropes will not immediately stop moving due to inertia. Therefore, the control device should determine the position of the target lifting container at which the movement of the traction rope is stopped as the current position when acquiring the current position of the target lifting container.
The target lifting container is a lifting container which is loaded with a target object in the first lifting container and the second lifting container. Generally, the number of the target lifting containers should be one.
In an application, the current position may be a relative position with a start position or an end position of the target lifting container as an origin, which is not limited. The control device may determine the current position according to the distance measuring sensor located on the target lifting container, which is not limited herein.
In application, the target object includes, but is not limited to, a human, an animal, a mine resource, or other objects.
In another embodiment, the weight of the first or second lifting container should generally remain unchanged when it is not carrying the target object. Therefore, the control device can also compare the weight of the first lifting container or the weight of the second lifting container with the original weight of the first lifting container or the second lifting container to determine the target lifting container.
And S204, controlling the target lifting container according to the current position and a preset target position.
In an application, the target position may be a start position or an end position of the target lifting container, and is not limited in this respect. It will be appreciated that when the target hoist container is in a lowering motion, its starting position is the mine exit position and its ending position is the mine bottom position. Conversely, the starting position of the target hoist container in the upward movement is the mine bottom position and the end position is the mine exit position, which will not be described in detail.
In application, the controlling of the target lifting container may be: the control target hoist container reaches the start position or the end position, and may also stop moving for the control target hoist container. Specifically, the control termination may determine a separation distance between the current position and the target position; and then, if the spacing distance is smaller than or equal to the preset distance, controlling the lifting system to stop working.
In application, the preset distance may be preset by a worker. Illustratively, the predetermined distance is 0.5m. It will be appreciated that when the separation distance is less than the predetermined distance, i.e. the target vessel has just left the starting position, or is about to reach the end position. At this time, for the target object in the target lifting container, the rescuer may rescue the target object directly at the start position or the end position. Therefore, the control device does not need to control the target lifting container so as to avoid secondary damage to the lifting system.
In another embodiment, if the spacing distance is greater than the preset distance and the working temperature of the disc brake is less than or equal to the normal working temperature, controlling the disc brake to output a second braking torque; the second braking torque is smaller than the braking torque output by the disc brake when the lifting system is in an abnormal state.
It can be understood that, if the separation distance is greater than the preset distance, it indicates that the separation distance between the target lifting container and the target position is relatively long, and the rescuers cannot rescue the target object of the target lifting container directly at the starting position or the ending position. The control device can thus also control the hoisting system again in dependence on the operating parameters of the hoisting system during operation.
It should be noted that, if the operating temperature of the disc brake is less than or equal to the normal operating temperature, it indicates that the abnormal state of the hoisting system is caused not by the operating temperature of the disc brake but by the current moving speed of the traction rope exceeding the preset normal speed. Based on this, the control termination may control the disc brake to output the second braking torque in order to decrease the current moving speed of the traction rope.
Wherein the second braking torque should be smaller than the braking torque output by the disc brake when the hoisting system is in an abnormal state. Based on this, the haulage rope can be made to slowly drive the target lifting container to move so as to ensure the safety of the target object.
In another embodiment, the second braking torque should be smaller than the braking torque output by the disc brake when the lifting system is in an abnormal state, and should also be smaller than the braking torque output by the disc brake when the traction rope moves at a preset normal speed. Otherwise, the hoist system will still be in an abnormal state.
Similarly, if the spacing distance is greater than the preset distance and the working temperature of the disc brake is greater than the normal working temperature, the disc brake is controlled to stop working.
It will be appreciated that at operating temperatures of the disc brake greater than the normal operating temperature, this is an indication that the disc brake is not suitable for operation at that time. Therefore, the control termination can directly control the disc brake to stop working until the working temperature of the disc brake is lower than the normal working temperature.
In the embodiment, the current moving speed of the traction rope during the operation of the lifting system and the working temperature of the disc brake are obtained to comprehensively judge the working state of the lifting system, so that the accuracy of judging the working state of the lifting system is improved. Then, when the lifting system is determined to be in an abnormal state according to the operation parameters, the current positions of the target lifting containers with the target objects loaded in the first lifting container and the second lifting container can be obtained, so that the target lifting containers are controlled according to the current positions and the preset target positions. Therefore, when a fault occurs in the transportation process of the lifting system, the target lifting container can be actively controlled, so that the trapped target object can be actively rescued, the trapped time of the target object is shortened, and the transportation safety of the lifting system is improved.
In another embodiment, if the current moving speed is less than or equal to the preset normal speed and the working temperature is less than or equal to the normal working temperature, it is determined that the lifting system is in the normal state. At this time, in order to further enable the traction rope to stably drive the target lifting container to operate, the control device may further control the braking torque output by the disc brake according to the current moving speed.
Specifically, if the current moving speed is equal to a preset target speed, maintaining a first braking torque currently output by the disc brake unchanged; and if the current moving speed is not equal to the preset target speed, adjusting the first braking torque currently output by the disc brake according to the target speed and the current moving speed.
In application, the target speed can be set according to actual conditions, and for example, the target speed can be 0.8m/s. It will be appreciated that when the current speed of movement is equal to the preset target speed, it indicates that the pull-cord is now moving at the target speed. Therefore, the control device can maintain the first brake torque currently output by the disc brake.
However, the current moving speed may be greater or less than the target speed due to other external influences (e.g., temperature and humidity of the lifting system operation). In order to keep the current moving speed of the traction rope stable, the first braking torque output by the penalty brake should be adjusted.
Specifically, if the current moving speed is greater than the target speed and the difference between the current moving speed and the target speed is greater than a preset speed threshold, the first braking torque is reduced to a first target braking torque; the difference between the first target braking torque and the first braking torque is a preset torque; if the current moving speed is smaller than the target speed and the difference value between the current moving speed and the target speed is smaller than or equal to a preset speed threshold, increasing the first braking torque to a second target braking torque; the difference between the second target braking torque and the first braking torque is a preset torque.
In application, if the speed difference between the current moving speed and the target speed is greater than the preset speed threshold value, and the current moving speed is greater than the target speed, it indicates that the first braking torque output by the disc brake is too large. Thus, the hoist system may reduce the first brake torque to the first target brake torque to reduce the current moving speed of the traction rope to gradually reduce the current moving speed to the target speed.
Similarly, as can be seen from the above explanation, if the speed difference between the current moving speed and the target speed is less than or equal to the preset speed threshold, and the current moving speed is less than the target speed, it indicates that the second braking torque output by the disc brake is too small. Therefore, the lifting system can increase the first braking torque to the second target braking torque to lift the current moving speed of the traction rope, so that the current moving speed is gradually increased to the target speed.
The preset speed threshold and the preset torque can be preset according to actual conditions, and are not limited. For example, in the present embodiment, the preset speed threshold may be 0.
It should be noted that, if the current moving speed is greater than the target speed, and the difference between the current moving speed and the target speed is greater than the preset speed threshold, and after the first braking torque is reduced to the first target braking torque, the moving speed of the traction rope at the next moment may be smaller than the target speed. But the difference between its moving speed and the target speed at the next moment will typically be less than or equal to the preset speed threshold. At this time, the control device may not need to adjust the first target braking torque. Otherwise, the preset torque is increased for the first target braking torque, and the braking torque output by the disc brake is the first braking torque.
