Technical Field

[0001] The utility model relates to the field of vertical track operation monitoring equipment, in particular to a mine shaft skip lifting and positioning system using a scale ruler for measurement. Background Art

[0002] Mine shaft skip hoisting systems are essential equipment in the mining process. Their primary function is to efficiently and safely transport ore, personnel, and equipment vertically within the shaft. With the continuous development of the mining industry and technological advancements, traditional hoisting methods are no longer able to meet the safety, efficiency, and cost-effectiveness requirements of modern mines. Therefore, the development and implementation of advanced skip hoisting systems is becoming increasingly important.

[0003] As mine operations continue to grow in depth and complexity, traditional lifting systems, particularly in deep-lying mineral resource extraction, face numerous challenges, including low transport efficiency, high failure rates, and operational safety hazards. These issues not only impact mine production efficiency but can also lead to safety accidents, resulting in significant economic losses and social liability for enterprises. Utility Model Content

The skip lifting and positioning system uses a scale ruler to realize non-contact absolute position detection, with fast detection speed, high accuracy and simple structure.

[0005] A mine shaft skip lifting and positioning system using a scale ruler for measurement includes a transverse bracket fixed to the mine shaft wall, a vernier pointer bracket fixed to the skip car body, and also includes a ground electrical cabinet, a scale ruler, a tensioning device and a vernier pointer. The scale ruler is vertically arranged parallel to the up and down movement direction of the skip, and is vertically tensioned by the tensioning devices arranged at the head and tail ends, and is locked and positioned by several of the transverse brackets. The vernier pointer is fixed on the vernier pointer bracket. When the skip moves up and down, the vernier pointer moves corresponding to the scale ruler. The ground electrical cabinet is used to supply power to the scale ruler, collect signals and output address signals.

[0010] As a preferred embodiment of the above technical solution, the horizontal distance between the scale and the vernier pointer is but not limited to 100 mm.

[0011] The friendship effect of the present invention is:

[0012] 1. The skip lifting and positioning system uses scale positioning to create a lifting system that integrates efficiency, safety and reliability. The system adopts advanced scale positioning technology to ensure the accuracy and stability of each lifting operation, which can significantly improve the transportation capacity of the mine while minimizing operational risks.

[0013] 2. Using a scale ruler for positioning can reduce the risk of the skip getting stuck, causing wire rope breakage and falling into the well.

DETAILED DESCRIPTION

[0020] The following is a clear and complete description of the technical solution of the present invention in conjunction with the accompanying drawings. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] like Figures 1 to 4 The shown system is a mine shaft skip lifting and positioning system that uses a scale ruler for measurement, including a transverse bracket 1 fixed to the mine shaft wall, a vernier pointer bracket 3 fixed to the skip car body 2, and also includes a ground electrical cabinet 4, a scale ruler 5, a tensioning device 6 and a vernier pointer 7. The scale ruler 5 is vertically arranged parallel to the up and down movement direction of the skip, and is vertically tensioned by the tensioning devices 6 arranged at the head and tail ends, and is locked and positioned by several of the transverse brackets 1. The vernier pointer 7 is fixed on the vernier pointer bracket 3. When the skip moves up and down, the vernier pointer 7 moves corresponding to the scale ruler 5. The ground electrical cabinet 4 is used to supply power to the scale ruler 5, collect signals and output address signals.

[0022] In this embodiment, the bucket is powered by a vehicle-mounted explosion-proof battery 8, and the generator on the bucket that is connected to the signal of the scale 5 is an explosion-proof generator 9. The signal emitted by the explosion-proof generator 9 is transmitted to the vernier pointer 7 through electromagnetic coupling.

[0023] In this embodiment, the tensioning device 6 at each end includes two groups of tensioning units arranged in an eight-shaped shape, one end of the tensioning unit is fixedly connected to the tensioning support 10, and the other end is fixedly connected to the scale 5.

[0024] It should be noted that the tensioning unit is a conventional tensioning device, which consists of components such as a screw sleeve 601, a screw with a pull ring on the head 602, a connecting rod 603, a switching block 604, and a wire rope 605. The tension can be adjusted by adjusting the screw 602, and the wire rope 605 can be used to facilitate the adjustment of the pulling angle, which is used to form a stable figure eight tensioning structure.

[0025] In this embodiment, the horizontal supports 1 are arranged at vertical intervals of 2-3 meters.

[0026] In this embodiment, the transverse support 1 is limited by a horizontal beam 11 fixed in the wellbore.

[0027] It should be noted that the horizontal bracket 1 is a conventional positioning bracket. Its base 101 is fixedly connected to the horizontal beam 11 via screws 102. The horizontal positioning plate 103 and base 101 can be reinforced by ribs 104. The end of the horizontal positioning plate 103 cooperates with a U-shaped plate 105 and a screw and nut assembly 106 to clamp and limit the scale 5. The horizontal brackets 1 are arranged vertically at intervals of 2-3 meters to distribute the weight of the scale 5.

[0028] In this embodiment, the horizontal distance between the scale 5 and the vernier pointer 7 is but not limited to 100 mm.

[0029] It is necessary to supplement the description that the optimal distance between the scale 5 and the vernier pointer 7 is subject to on-site debugging, and the distance with the best signal transmission capability is the basis under the premise of ensuring no contact friction.

[0030] The working principle of this embodiment is as follows.

[0031] The scale 5 is fixed on the wall of the mine shaft in the vertical direction through the horizontal bracket 1. The test depth of the scale 5 can reach 220 meters and it is set parallel to the skip track. The ground electrical cabinet 4 is fixed on the head end of the scale 5 on the ground to supply power to the scale 5 and collect signals and output address signals. The tensioning device 6 is set at the head and tail end of the scale 5 for vertically tightening the scale 5. The vernier pointer bracket 3 fixed on the skip car body 2 is connected to the vernier pointer 7. When the skip moves up and down, the vernier pointer 7 corresponds to the movement of the scale 5. The vernier pointer 7 is set 1 meter apart from the scale 5. 00mm or so; the on-board explosion-proof battery 8 fixedly mounted on the skip car body 2 supplies power to the explosion-proof generator 9, and the signal emitted by the explosion-proof generator 9 is transmitted to the vernier pointer 7 by electromagnetic coupling. The vernier pointer 7 generates an alternating magnetic field and is transmitted to the induction loop of the scale scale 5. The scale scale 5 is in a uniformly distributed alternating magnetic field, and the core wire of the scale scale 5 will generate an induced electromotive force signal. The scale analyzer inside the ground electrical cabinet 4 receives the signal of the scale scale 5 and performs phase comparison, thereby giving the position of the vernier pointer 7 in the length direction of the scale scale 5, i.e., the position of the skip traveling.

[0032] When the scale scale mine shaft skip lifting and positioning system described in the utility model is used in the daily operation of the mine, the automatic positioning and unmanned operation of the skip are realized through the positioning system, thereby reducing the labor intensity of the operators. By integrating the real-time position information of the skip into the winch control system PLC and communicating with the host computer, the operator can remotely monitor the running status of the skip on the host computer and perform operations. By monitoring the position of the skip in real time, the jamming fault of the skip can be detected in time, and an alarm can be issued to avoid serious production accidents. The service life of the equipment can be extended, precise operation can be achieved, the process can be optimized, the probability of human error can be reduced, the unloading efficiency can be improved, and production costs can be saved.

[0033] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
