Description
Technical Field
The invention relates to the field of mine hoisting equipment, in particular to a steel wire rope anti-loosening protection device.
Background
The mine hoist is a large-scale complex electromechanical system integrating the technologies of machine, electricity, liquid and control and detection, and is a junction and a throat which are connected with underground mine and ground, and is directly related to efficient operation and safe production of the mine.
For a mine inclined shaft hoist, when a hoisting container moves upwards on a slope track in a heavy load manner, emergency braking occurs due to faults or the hoisting container is influenced by inertia before and after a track slope change point, and can continue to move upwards along the slope track, so that a hoist drum and the hoisting container are extremely easy to be asynchronous, and a steel wire rope is formed; when the lifting container runs down on the slope track, the lifting container is blocked or falls off, the lifting drum and the lifting container are easily asynchronous, the lifting wire rope is loosened, and the lifting container is in a traction-free state. When the rope loosening phenomenon of the steel wire rope occurs, that is, the speed of the lifting container is inconsistent with the winding speed of the steel wire rope of the lifting machine, the lifting container is in a traction-free state if the lifting container is light, and serious accidents such as rope breakage, sliding of the lifting container and the like can occur.
The existing rope-loosening protection devices mainly have three types: one is direct measurement, namely, a sensor is arranged below a winding drum of a hoist or at a certain position between the winding drum and a head sheave (usually arranged at the outlet of a steel wire rope of a hoist room), the degree of looseness of the steel wire rope is directly detected, and when the degree of looseness is to a certain degree, the sensor sends a signal to give an alarm to a hoist driver or cuts off the power supply of the hoist to carry out safety braking; the second is indirect measurement, which is to install sensors on the winding drum and the head sheave of the elevator respectively, detect the linear velocity of the winding drum and the head sheave, and indicate that the wire rope is in a tensioning state if the linear velocities are equal; if the linear speed of the winding drum is greater than that of the head sheave, the wire rope is loosened, and alarming or safety braking is carried out when a certain rope loosening amount is achieved. And thirdly, measuring force, and judging whether the steel wire rope is in a rope loosening condition according to the stress condition on the steel wire rope tensioning device.
The direct measurement type rope-loosening protection device is mostly used for detecting faults by a travel switch, and is also used for detecting faults by a proximity switch or a photoelectric technology. Because of its lowest cost, it is easy to work with more than 90% of mines. When the rope loosening fault occurs, the steel wire rope sags and contacts with the travel switch below the steel wire rope, so that an alarm and control circuit is connected, and the rope loosening protection function is realized. The disadvantages of this protection device are mainly the following: (1) the stroke of the stroke switch is controlled manually, the alarm is frequently given when the stroke is too small, and the protection effect cannot be achieved when the stroke is too large; (2) when the hook is taken off and the mine car runs to a slope changing point, misoperation of the rope loosening protection device is easy to occur, and the hoisting machine is caused to stop frequently; (3) the travel switch type rope loosening protection device has a failure section, and error information is brought to rope loosening detection of the steel wire rope. This method therefore has little substantial work on the rope-break protection.
The second is of the indirect measurement type, commonly used for vertical lift. The device is used for inclined shaft lifting misoperation too much, and because whether the speed of a lifting machine is consistent with the speed of a lifting container or not is really detected, the mounting speed sensor of the lifting container is not easy to realize due to explosion prevention and multiple mine cars. This method is therefore essentially unused.
The third is force measuring type, because the relative tension of the steel wire rope of the vertical shaft hoist is stronger than that of the inclined shaft, most of the steel wire rope is used on the vertical shaft hoist. The inclined shaft is provided with an attempt to install one between the head sheave and the hoisting machine winding drum, but the technology and the use cost of the first bearing are too high, the installation position of the second steel wire rope tensioning device is not an ideal position, and the problem of rope loosening cannot be solved.
Therefore, how to provide a wire rope anti-loosening protection device, so that the problem can be overcome, is a problem that needs to be solved by those skilled in the art.
