Description

Technical Field

[0001] This utility model relates to the field of transfer equipment technology, and in particular to a cable guiding device suitable for bidirectional shuttle car operation. Background Technology

[0002] The shuttle car is a short-distance transport device used in conjunction with mining equipment. Its main function is to transfer the coal mined by the mining equipment to the feed crusher, achieving efficient coal transportation. Due to its outstanding advantages such as easy maintenance, high safety, and flexible operation, it can greatly enhance the production capacity of mining equipment and reduce the labor intensity of workers. It is a powerful transfer device in underground coal mining operations and plays an important role in coal mining production.

[0003] Traditional shuttle cable guiding devices can only face one direction. If the shuttle is equipped with a 200-meter-long cable, its maximum transport distance is 200 meters. This cable guiding device restricts the extension of the shuttle's transport distance, which limits its use in some special mines. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention provide a cable guiding device suitable for bidirectional shuttle operation, which can extend the shuttle's transport distance and improve its transport efficiency.

[0005] This utility model embodiment proposes a cable guiding device suitable for bidirectional shuttle operation, comprising: a base plate and a fourth roller. The upper end of the base plate is rotatably connected to a first roller, a second roller, and a third roller, respectively. The first roller, the second roller, and the third roller are of equal height and all rotate in the horizontal direction. The axes of the first roller, the second roller, and the third roller are triangularly distributed. The fourth roller is connected above the first roller, the second roller, and the third roller by a bracket. The fourth roller is rotatably connected to the bracket and rotates in the vertical direction. A gap is left between any two adjacent rollers of the first roller, the second roller, the third roller, and the fourth roller for the cable to pass through. At least two of the first roller, the second roller, the third roller, and the fourth roller are in contact with the cable.

[0006] In some embodiments, the bracket includes a first bent plate and a second bent plate. The first bent plate includes a first horizontal plate and a first vertical plate connected to each other. The first horizontal plate is connected above a second roller, and the second roller is rotatably connected to the first horizontal plate via a pivot.

[0007] The second curved plate includes a second horizontal plate and a second vertical plate connected to each other. The second horizontal plate is connected above the first roller and the third roller. The first roller is rotatably connected to one side of the second horizontal plate via a rotating shaft. The third roller is rotatably connected to the other side of the second horizontal plate via a rotating shaft. The first vertical plate and the second vertical plate are respectively connected to the two end faces of the fourth roller. The two ends of the fourth roller are respectively rotatably connected to the first vertical plate and the second vertical plate via rotating shafts.

[0008] In some embodiments, the length of the second horizontal plate is greater than the length of the first horizontal plate.

[0009] In some embodiments, the base plate has a triangular structure, with the first roller, the second roller, and the third roller respectively connected to the three corners of the base plate.

[0010] In some embodiments, the second vertical plate has a triangular structure.

[0011] In some embodiments, the outer periphery of the first roller, the second roller, the third roller and the fourth roller are respectively provided with grooves, and the width of the grooves is greater than or equal to the outer diameter of the cable.

[0012] In some embodiments, the rotating shaft includes a pin and a retaining pin plate. The pin passes through the shaft hole of the roller, and at least one end of the pin has a slot.

[0028] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] The following description, with reference to the accompanying drawings, describes a cable guiding device suitable for bidirectional shuttle driving according to an embodiment of the present invention.

[0030] like Figure 1-9 As shown in the figure, this utility model embodiment proposes a cable guiding device suitable for bidirectional shuttle driving, including: a base plate 2 and a fourth roller 7. The upper end of the base plate 2 is rotatably connected to a first roller 1, a second roller 6 and a third roller 8, respectively. The first roller 1, the second roller 6 and the third roller 8 are at the same height and all rotate in the horizontal direction. The axes of the first roller 1, the second roller 6 and the third roller 8 are triangularly distributed. The fourth roller 7 is connected above the first roller 1, the second roller 6 and the third roller 8 through a bracket. The fourth roller 7 is rotatably connected to the bracket and rotates in the vertical direction. A gap is left between any two adjacent rollers of the first roller 1, the second roller 6, the third roller 8 and the fourth roller 7 for the cable 12 to pass through. At least two of the first roller 1, the second roller 6, the third roller 8 and the fourth roller 7 are in contact with the cable 12.

[0031] This utility model embodiment, by setting a base plate 2, a first roller 1, a second roller 6, a third roller 8 and a fourth roller 7, and through a bidirectional guiding design, can double the transportation distance, greatly improve the efficiency of shuttle transportation, and ensure that the cable 12 is smoothly retracted and extended during the shuttle's movement.

[0032] In use, the cable guiding device of this embodiment is installed near the outlet of the cable reel 11 on the shuttle car, typically on the left rear side of the shuttle car. The cable 12 is wound between the rollers and extends out of the cable guiding device to guide the cable 12. The power supply station is placed between the mining face and the crusher. The shuttle car reciprocates between the mining face and the crusher, with the direction facing the mining face defined as the forward direction. The power supply station is the fixed end of the cable 12. When the shuttle car moves away from the power supply station, the cable reel 11 unwinds; when the shuttle car moves towards the power supply station, the cable reel 11 automatically winds up.

[0033] like Figure 8 As shown, when the shuttle car moves from the power supply station towards the mining face, the power supply station is located behind the shuttle car. The shuttle car releases the cable as it moves forward, and at this time, the cable 12 is guided between the first roller 1, the second roller 6, and the third roller 8. When the shuttle car moves backward from the mining face, the shuttle car retracts the cable 12, and the first roller 1, the second roller 6, and the third roller 8 rotate in the opposite direction to guide it. Figure 8 The arrow in the image indicates the direction of advancing towards the mining site.

[0034] like Figure 9 As shown, when the shuttle car reverses past the power station, its front faces the power station and continues to reverse towards the crusher. At this time, the cable 12 is guided between the first roller 1 and the fourth roller 7, and the shuttle car releases the cable and reverses. When the shuttle car reaches the crusher and begins to move towards the power station, the shuttle car retracts the cable 12, and the first roller 1 and the fourth roller 7 rotate in the opposite direction to guide it. Figure 9 The arrow in the image indicates the direction of retreat towards the crusher.

[0035] For example, a shuttle car carrying a 200-meter-long cable can transport cables up to 400 meters in length. Figure 7 As shown.

[0036] It should be noted that turning around in the confined space of a mine is very difficult. By adopting the cable guiding device of this utility model embodiment, the shuttle can move underground without turning around, but by moving forward and backward. The spacing between the first roller 1, the second roller 6, the third roller 8 and the fourth roller 7 can be designed according to actual usage requirements (such as the specifications of the cable 12, the tightness of the cable 12 winding and unwinding, etc.).

[0037] In some embodiments, such as Figure 2 ,3 As shown in Figure 5, the bracket includes a first curved plate 3 and a second curved plate 9. The first curved plate 3 includes a first horizontal plate 32 and a first vertical plate 31 that are connected to each other. The first horizontal plate 32 is connected above the second roller 6, and the second roller 6 is rotatably connected to the first horizontal plate 32 through a rotating shaft.

[0038] The second curved plate 9 includes a second horizontal plate 92 and a second vertical plate 91 connected to each other. The second horizontal plate 92 is connected above the first roller 1 and the third roller 8. The first roller 1 is rotatably connected to one side of the second horizontal plate 92 via a rotating shaft. The third roller 8 is rotatably connected to the other side of the second horizontal plate 92 via a rotating shaft. The first vertical plate 31 and the second vertical plate 91 are respectively connected to the two end faces of the fourth roller 7. The two ends of the fourth roller 7 are respectively rotatably connected to the first vertical plate 31 and the second vertical plate 91 via rotating shafts.

[0039] By setting the first bending plate 3 and the second bending plate 9, the rollers can be limited on the one hand, and the space for guiding the cable 12 is also formed on the other hand, so that the cable 12 can be transmitted and reversed within the space enclosed by the four rollers.

[0040] In some embodiments, such as Figure 3 As shown, the length of the second horizontal plate 92 is greater than the length of the first horizontal plate 32. This is to facilitate the installation of the first roller 1 and the third roller 8, which are located on opposite sides of the second horizontal plate 92.

[0041] In some embodiments, such as Figure 1 As shown, the base plate 2 has a triangular structure, with the first roller 1, the second roller 6, and the third roller 8 connected to the three corners of the base plate 2 respectively. Since the arrangement of the first roller 1, the second roller 6, and the third roller 8 is triangular, designing the base plate 2 as a triangular structure can reduce the space occupied by the guiding device on the shuttle car.

[0042] Furthermore, the base plate 2 is shaped like an isosceles triangle, with the first roller 1 and the third roller 8 located at the two base angles of the isosceles triangle, and the second roller 6 located at the apex angle of the isosceles triangle.

[0043] In some embodiments, such as Figure 1 As shown, the second vertical plate 91 has a triangular structure.

[0044] Furthermore, the lengths of the second horizontal plate 92 and the second vertical plate 91 are both equal to the length of the base plate 2.

[0045] In some embodiments, such as Figure 1 , 4As shown, the outer circumferences of the first roller 1, the second roller 6, the third roller 8, and the fourth roller 7 are respectively provided with grooves, the width of which is greater than or equal to the outer diameter of the cable 12. By providing grooves, the cable 12 can be easily transported within the grooves, the guiding effect on the cable 12 is enhanced, and the wear of the support or base plate 2 on the cable 12 is reduced.

[0046] In some embodiments, such as Figure 5 As shown, the rotating shaft includes a pin 4 and a retaining pin 5. The pin 4 passes through the shaft hole of the roller, and at least one end of the pin 4 has a slot. After the retaining pin 5 is inserted into the slot, it is fixedly connected to the base plate 2 or the bracket by bolts. The retaining pin positions the pin 4, allowing the roller to rotate stably.

[0047] In some embodiments, such as Figure 5 As shown, a bushing 10 is connected between the shaft hole and the pin 4.

[0048] In some embodiments, the first roller 1, the second roller 6, the third roller 8, and the fourth roller 7 have the same structure and size.

[0049] In some embodiments, such as Figure 1 As shown, the corners of the base plate 2, the first horizontal plate 32, the second horizontal plate 92, the first vertical plate 31, and the second vertical plate 91 are all rounded to prevent wear on the cable 12.
