[0002] The Chinese invention patent with the authorization announcement number CN 104515777B on March 8, 2017 discloses a strong magnetic-image combined online non-destructive flaw detection system and method for steel wire ropes. In this system, each steel wire rope requires three cameras, which is a large number, high cost, and the angle is not adjustable. It is also impossible to detect the part of the head rope or tail rope by video. Summary of the invention

[0003] The technical problem to be solved by the present invention is how to fill the above-mentioned gap in the prior art and provide an adjustable bracket for head and tail rope monitoring, a head and tail rope intelligent monitoring system and a use method.

[0004] In order to solve the above technical problems, the adjustable bracket for monitoring the head and tail ropes of the present invention is characterized in that it includes a first fixed frame, a second fixed frame, an electric push rod and a parallelogram frame, the first fixed frame and the second fixed frame are respectively fixed to the sheave platform of the mine hoist or the bottom side wall of the shaft of the mine hoist, and a central vertical axis is respectively provided on the first fixed frame and the second fixed frame, and the axis center lines of the two central vertical axes and the axis center lines of the head rope and tail rope of the mine hoist are all on the same vertical plane.

[0005] The parallelogram frame includes a front transverse horizontal frame, a rear transverse horizontal frame, a first longitudinal horizontal frame on the left, a second longitudinal horizontal frame on the left, a first longitudinal horizontal frame on the right and a second longitudinal horizontal frame on the right. A middle hole is respectively provided in the middle section of the front and rear transverse horizontal frames, and the middle vertical axis is sleeved on the middle hole.

[0006] Two side vertical holes are respectively arranged on the front and rear transverse horizontal frames on both sides of the middle hole, the first and second longitudinal horizontal frames on the left side and the first and second longitudinal horizontal frames on the right side are respectively located on both sides of the same vertical plane where the axis lines of the head rope and the tail rope are located, and the first and second longitudinal horizontal frames on the left side and the first and second longitudinal horizontal frames on the right side are respectively hinged on the side vertical holes on both sides of the front and rear transverse horizontal frames.

[0007] The middle sections of the first and second longitudinal horizontal frames on the left side and the first and second longitudinal horizontal frames on the right side are respectively provided with N hinge holes, the second fixed frame extends an extension arm to one side, one end of the electric push rod is hinged on the extension arm through a vertical axis, and the other end of the electric push rod is hinged and fixed to a corner of the parallelogram frame through a vertical axis, and when the electric push rod is extended or retracted, the parallelogram frame can be driven to deform, wherein N is a positive integer, and N is equal to the number of first rope strands of the mine hoist or the number of tail rope strands of the mine hoist.

[0008] When in use, the intrinsically safe intelligent high-speed cameras are divided into two groups, and fixed one by one to the hinge holes on the first and second longitudinal horizontal frames on the left side and the first and second longitudinal horizontal frames on the right side of the adjustable bracket for monitoring the head and tail ropes through vertical axis hinge connection. With such a design, by controlling the extension and contraction of the electric push rod, the parallelogram frame is deformed, and then the head rope or tail rope between the relative intrinsically safe intelligent high-speed cameras is driven to rotate a certain angle, and only two intrinsically safe intelligent high-speed cameras need to be installed around one wire rope.

[0009] The high-speed head and tail rope intelligent monitoring system of the mine hoist of the present invention comprises a mine shaft, an intrinsically safe intelligent high-speed camera, a flameproof fill light, a cage, a waterproof cabinet and an operator station, the waterproof cabinet is electrically connected to the intrinsically safe intelligent high-speed camera and the flameproof fill light respectively, and the operator station is electrically connected to the waterproof cabinet, characterized in that: it also includes the aforementioned adjustable bracket for monitoring the head and tail ropes, the intrinsically safe intelligent high-speed camera and the flameproof fill light are 2N in number, each flameproof fill light is fixed on an intrinsically safe intelligent high-speed camera in a one-to-one correspondence, all intrinsically safe intelligent high-speed cameras are divided into two groups, and are fixed on the hinge holes on the first and second longitudinal horizontal frames on the left side and the first and second longitudinal horizontal frames on the right side of the adjustable bracket for monitoring the head and tail ropes in a one-to-one relative manner through a vertical axis hinge, the motor control circuit of the electric push rod is electrically connected to the waterproof cabinet, and when the electric push rod is extended and retracted, the parallelogram frame can be driven to deform, and at the same time, each intrinsically safe intelligent high-speed camera rotates a certain angle around the axis of the head rope or tail rope facing its lens. Such a design has the same advantages as above.

[0010] As an optimization, the No. 1 mobile inspection device track and the No. 2 mobile inspection device track are installed on the upper sheave platform or the lower shaft wall of the mine hoist. The No. 1 mobile inspection device track and the No. 2 mobile inspection device track are equipped with multiple rollers. Both the No. 1 and No. 2 mobile inspection devices are magnetic flaw detection sensors. With this design, the magnetic flaw detection sensor can be used to perform a rough inspection of the head rope or tail rope, and then the magnetic flux mutation point of the head rope or tail rope can be used for accurate image and video detection, which is convenient and fast.

[0011] The method of the present invention using the above-mentioned mine hoist high-speed head and tail rope intelligent monitoring system to perform local video detection of the head rope or the tail rope includes the following steps:

[0012] ①. Use the No. 1 and No. 2 mobile inspection devices to perform electromagnetic detection on the head rope or tail rope of each mine hoist. When a sudden change in magnetic flux is found in the head rope or tail rope, record the position of the sudden change in magnetic flux of the head rope or tail rope;

[0013] ②. Control the mine hoist so that the head rope or tail rope with a sudden change in magnetic flux moves to the intrinsically safe intelligent high-speed camera, and stops when the sudden change in magnetic flux is exactly between the intrinsically safe intelligent high-speed cameras on both sides. Then, extend the electric push rod from the shortest state to the longest state, or retract it from the longest state to the shortest state. During this period, the intrinsically safe intelligent high-speed camera facing the sudden change in magnetic flux of the head rope or tail rope takes continuous high-speed photos;

[0014] ③. Then, the obtained photos are transmitted to the computer in the operator station. The computer first plays on the computer screen in the order of shooting at a playback speed of more than 24 frames per second the photos of the location where the magnetic flux of the head rope or tail rope changes suddenly, taken by the intrinsically safe intelligent high-speed camera on one side of the location where the magnetic flux of the head rope or tail rope changes suddenly. Then, in the order of shooting, the photos of the location where the magnetic flux of the head rope or tail rope changes suddenly, taken by the intrinsically safe intelligent high-speed camera on the other side of the location where the magnetic flux of the head rope or tail rope changes suddenly, are played. The staff judges whether the steel wire at the location where the magnetic flux of the head rope or tail rope changes suddenly is broken, bulged, twisted, worn or rusted by viewing the video.

[0015] With such a design, by comparing the sudden change of magnetic flux of the head rope or tail rope through video playback, it is easier to find the protruding local raised iron wire or broken wire and the locally defective steel wire at the sudden change of magnetic flux of the head rope or tail rope.

[0016] The adjustable bracket for monitoring the head and tail ropes, the intelligent monitoring system for the head and tail ropes and the use method of the present invention have the advantages of adjustable shooting angle and local observation of the head rope or the tail rope in video form, which is conducive to quickly discovering damage to the head rope or the tail rope and helps to speed up the inspection and maintenance process of the head rope or the tail rope.
