Description

Technical Field

[0001] The present invention relates to a wire rope replacement method for a mine hoisting system based on a rope changing vehicle, in particular to a coordinated rope replacement method of a clamping and conveying unit based on the same rope changing vehicle, belonging to the technical field of wire rope replacement for a mine hoisting system. Background Art

[0002] A mine hoisting system is a system used to transport ore, coal, waste rock, or gangue along a mine shaft, as well as to raise and lower personnel, equipment, and other equipment. Wire rope mine hoisting systems, which use wire ropes to propel a hoisting container along a shaft or ramp, are the most widely used. Commonly used wire rope mine hoisting systems in my country are primarily single-rope winding and multi-rope friction types.

[0003] Wire rope is the most important component of a wire rope mine hoisting system and plays a vital role in the safe hoisting of a mine. The "Coal Mine Safety Regulations" have strict regulations on the service life and replacement cycle of wire rope. For wire rope mine hoisting systems, especially multi-rope friction mine hoisting systems, wire rope replacement is a high-risk, accident-prone, labor-intensive, and time-consuming operation. The application of wire rope replacement technology using a rope changing vehicle has greatly improved the current situation of using traditional equipment for wire rope replacement, which is time-consuming, labor-intensive, and has significant safety risks. It can significantly improve the efficiency and safety of wire rope replacement in mine hoisting systems.

[0004] In order to maintain the stability of the original head rope tension of the mine hoisting system, the rope changing car usually has the function of releasing the new rope while collecting the old rope. That is, the rope changing car usually has at least two clamping and conveying units arranged side by side, one for releasing the new rope and the other for collecting the old rope. However, due to the length limitation of the clamping and conveying unit, the friction conveying force of the clamping and conveying unit is generally less than 15 tons. For modern mines with large rope diameters and ultra-deep wells, the weight of the wire rope often exceeds the friction conveying force of the clamping and conveying unit of the rope changing car. This makes the traditional process of using a single rope changing car to change ropes unable to complete the rope changing operation. In the existing technology, there is a method of using multiple rope changing cars to work together to change ropes. However, the collaborative operation of multiple rope changing cars not only makes it difficult to accurately control the synchronization of multiple rope changing cars, but also involves key technologies such as collaborative control algorithms, communication protocols, tension closed-loop control, etc. that need to be customized according to specific needs. In addition, it has high site requirements and requires a large number of personnel, making collaborative operation difficult and the cost of rope changing high. Summary of the Invention

[0005] In response to the problems existing in the above-mentioned prior art, the present invention provides a method for collaborative rope changing using a clamping and conveying unit based on the same rope changing vehicle, which can reduce the rope changing cost while doubling the friction conveying force of the same rope changing vehicle.

[0006] In order to achieve the above-mentioned purpose, the present invention is based on the coordinated rope changing method of the clamping and conveying units of the same rope changing vehicle. The wire rope clamped and conveyed by the clamping and conveying unit I of the same rope changing vehicle is redirected by a redirecting conveying device and then sent to the clamping and conveying unit II for clamping and conveying. The clamping and conveying unit I and the clamping and conveying unit II are synchronously controlled to perform clamping and conveying actions in opposite directions, thereby increasing the friction conveying force of the same rope changing vehicle.

[0007] The redirecting conveying device includes a rear redirecting conveying part and a front guiding part;

[0008] The rear redirection conveying part includes a chassis, a lifting mechanism and a redirection conveying platform. The redirection conveying platform is installed on the chassis through the lifting mechanism. The front end of the redirection conveying platform is also provided with a rope-changing vehicle positioning and connection mechanism. The redirection conveying platform is provided with a redirection conveying mechanism for redirecting the wire rope output from the clamping conveying unit I or clamping conveying unit II of the same rope-changing vehicle and then feeding it into the clamping conveying unit II or clamping conveying unit I.

[0009] The front guide part comprises a front guide wheel which can be mounted on the front end of the rope changing vehicle through a supporting frame, and the front guide wheel is correspondingly arranged in front of the clamping and conveying unit.

[0010] As a further improvement of the present invention, before the rope changing operation, the height of the redirecting conveying platform is adjusted to correspond to the conveying height of the clamping conveying unit by controlling the lifting mechanism, and then the entire rear redirecting conveying part is fixedly connected to the rear end of the rope changing vehicle through the rope changing vehicle positioning connection mechanism, and the front guide part is correspondingly installed at the front end of the rope changing vehicle;

[0011] When collecting the old rope, the old rope is redirected by the front guide wheel of the rope-changing vehicle and sent to the front end of the clamping and conveying unit I of the rope-changing vehicle. The clamping and conveying unit I of the rope-changing vehicle is driven to perform a forward clamping and conveying action so that the end of the old rope is output from the rear end of the clamping and conveying unit I. After the old rope is redirected by the redirecting conveying mechanism of the redirecting conveying platform, the end of the old rope is sent to the rear end of the clamping and conveying unit II. The clamping and conveying unit I of the rope-changing vehicle is driven to perform a forward clamping and conveying action while the clamping and conveying unit II is driven to perform a reverse clamping and conveying action so that the end of the old rope is output from the front end of the clamping and conveying unit II. Then the end of the old rope passes around the front guide wheel and is led out to the rope-collecting winch for collecting the old rope.

[0012] When feeding a new rope, the new rope released by the rope-releasing winch is sent to the front end of the clamping and conveying unit II after passing over the front guide wheel. The clamping and conveying unit II of the rope-changing vehicle is driven to perform a forward clamping and conveying action so that the rope head of the new rope is output from the rear end of the clamping and conveying unit II. After the new rope is redirected by the redirecting conveying mechanism of the redirecting conveying platform, the rope head of the new rope is sent to the rear end of the clamping and conveying unit I. The clamping and conveying unit II of the rope-changing vehicle is driven to perform a forward clamping and conveying action while the clamping and conveying unit I is driven to perform a reverse clamping and conveying action so that the rope head of the new rope is output from the front end of the clamping and conveying unit I. The rope head of the new rope is then redirected over the front guide wheel of the rope-changing vehicle and sent to the wellhead.

[0014] As a further improvement of the present invention, the arc-shaped guide rail of the conveying support guide rail is a multi-segment structure including a plurality of arc-shaped segments, and the arc-shaped segments are connected to the diameter-changing control mechanism.

[0015] As a further improvement of the present invention, the tensioning wheel is a sprocket structure that cooperates with the conveyor chain, and a tensioning wheel rotation drive mechanism is provided on the tensioning wheel;

[0016] The tension wheel is controlled to actively rotate and drive the conveyor chain by controlling the action of the tension wheel rotation drive mechanism, or the tension wheel is controlled to perform damping braking by controlling the action of the tension wheel rotation drive mechanism.
