[0028] The following describes exemplary embodiments of the present invention in more detail with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0029] The utility model provides a comprehensive detection system for bucket tilt, see Figure 1-Figure 2 , at least includes: a pull-wire detection switch 101, a beam photoelectric switch 102, a field control device 103, a main shaft hoisting control device 104 and a hoist 105. The hoist 105 is controlled by the main shaft hoisting control device 104 to lift the skip.

[0030] in, Figure 1 This is an installation example diagram of the detection switch and bucket. Figure 2 It is a module diagram of the comprehensive detection system for skip tilt.

[0031] Inside the shaft, there are one or more skips 106, with no specific limit. The skips are hoisted by the hoist 105 inside the shaft 106. The ideal state of the skips 106 inside the shaft is to keep them running vertically. However, due to various reasons, the skips 106 may tilt inside the shaft. Figure 3 , is a schematic diagram of the tilt of the skip, wherein the dotted line illustrates the tilt state of the skip 106.

[0032] To promptly detect whether the bucket is tilting, the present invention's comprehensive bucket tilt detection system incorporates a pull-wire detection switch 101 and a beam-type photoelectric switch 102 to detect bucket tilt. The pull-wire detection switch 101 and beam-type photoelectric switch 102 are electrically connected to a field control device 103, which is interlocked with the main shaft hoisting device. When the bucket tilts, the field control device 103 issues an alarm signal and controls the hoist 105 to stop for protection. This not only improves the reliability and accuracy of bucket tilt detection, but also reduces the safety risk of scrapes on shaft equipment and shaft tower structures caused by a tilted bucket, shortening production downtime and minimizing the economic losses caused by such scrapes.

[0033] In one embodiment, the shaft equipment is installed at the lower part of the shaft, mainly including shaft steel structure, tankway beams, tankway wood, backrest beams, frame beam metering tongue plates and other equipment; the shaft tower is a concrete structure above the shaft, and the skip needs to run a certain distance in the shaft tower. When the skip is tilted, the edge of the skip will scratch the concrete structure of the shaft tower.

[0034] Since bucket tilt can occur at any part of the bucket, the pull-wire detection switch 101 includes a pull rope and a detection switch, which are fixed to two points on the inner wall of the wellbore, so that the pull rope is stretched between the two points on the inner wall of the wellbore. Alternatively, the pull rope and the detection switch are fixed to two pillars, so that the pull rope is stretched between the two pillars.

[0035] Taking the bucket unloading parking position as an example, it is inside the well tower. Therefore, the specific location of the pull-wire detection switch 101 can be designed to be 3-5 meters below the bucket unloading parking position, and of course other locations are also possible. In addition, the utility model does not limit the number of pull-wire detection switches 101. In actual application, one or more pull-wire detection switches 101 can be used according to actual conditions.

[0036] The pull cord of the pull-cord detection switch 101 is parallel to the edge of the bucket when it is not tilted, and maintains a set distance from the edge of the bucket when it is not tilted, such as 5 mm, but this is not a limit. When the bucket tilts, it touches the pull cord, causing the detection switch to operate and generate a first detection signal.

[0037] Specifically, when the bucket is not tilted or tilted less than 5mm, the pull rope maintains a certain distance from the bucket edge, which does not trigger the detection switch to generate the first detection signal. However, when the bucket tilts more than 5mm, the bucket edge will touch the pull rope, causing the detection switch to generate the first detection signal.

[0038] The field control device 103 is connected to the pull-wire detection switch 101 and is interlocked with the main shaft hoisting control device 104. When the field control device 103 receives the first detection signal, it can control the hoist 105 to stop according to the first detection signal.

[0039] In one embodiment, the present invention designs a through-beam photoelectric switch 102 , which is redundant with the wire-pulling detection switch and plays a role of redundant detection.

[0040] The beam-type photoelectric switch 102 is installed at two points on the inner wall of the wellbore or between two columns.

[0041] Specifically, the beam-type photoelectric switch 102 includes two action switches, which are fixed at two points on the inner wall of the wellbore, or fixed at two columns.

[0042] Taking the bucket unloading parking position as an example, it is inside the well tower. Therefore, the specific installation position of the through-beam photoelectric switch 102 can be designed to be 3-5 meters below the bucket unloading parking position, but other locations are also possible. In addition, the utility model does not limit the number of through-beam photoelectric switches 102. In actual application, one or more through-beam photoelectric switches 102 can be used according to actual conditions.

[0043] A beam of light is generated between the two active switches of the through-beam photoelectric switch 102. The beam of light is parallel to the edge of the bucket when it is not tilted, and maintains a set distance from the edge of the bucket when it is not tilted, such as 5 mm, but this is not a limit. When the bucket is tilted, the beam of light is blocked, triggering the through-beam photoelectric switch 102 to generate a second detection signal.

[0044] Specifically, when the bucket is not tilted or tilted less than 5mm, the light remains at a certain distance from the bucket edge, and the through-beam photoelectric switch 102 does not trigger the second detection signal. However, when the bucket tilts more than 5mm, the bucket blocks the light, triggering the through-beam photoelectric switch 102 to generate the second detection signal.

[0045] The field control device 103 is connected to the beam-type photoelectric switch 102 and controls the hoist 105 to stop according to the second detection signal.

[0046] In one embodiment, in order to perform an audible and visual alarm, an audible and visual alarm component is designed inside the field control device 103 to perform an audible and visual alarm according to the first detection signal. Of course, an audible and visual alarm can also be performed according to the second detection signal.

[0047] The field control device 103, controlled by a PLC, receives a detection signal generated by a detection switch when the field skip is tilted. Through program judgment, it interlocks with the hoist 105 system to immediately stop the hoist 105. In addition, the field control device 103 generates an audible and visual alarm to alert personnel on duty and promptly investigate the tilting skip.

[0048] In one embodiment, the skip tilt comprehensive detection system further includes: a camera device and a display device; the camera device is located in the wellbore or on a column; the position of the display device is not limited, for example, it is located above the well.

[0049] The field control device 103 is connected to the camera device and the display device respectively. When the skip bucket tilts, the camera device is controlled to take pictures of the tilting scene and transmit them to the display device for display, so that the personnel on the well can check the specific tilting situation of the skip bucket.

[0050] In one embodiment, the skip tilt comprehensive detection system further includes a terminal device that is communicatively connected to the field control device 103 and remotely receives and displays photos of the tilting scene. For example, the field control device 103 is communicatively connected to a remote control room, allowing the remote control room to view the field skip tilt situation in real time.

[0051] After the system of the utility model is implemented, the state of the skip can be detected in real time through comprehensive detection after the skip tilts, thereby improving the accuracy of the skip tilt detection, avoiding accidents of scratching the shaft equipment caused by the tilted skip, reducing the downtime of the main shaft hoisting system of the underground mine, and reducing the economic losses caused by the scratches.
