Description

Technical Field

[0001] This utility model relates to the field of mining machinery and equipment manufacturing technology, and in particular to a curved track that facilitates transportation. Background Technology

[0002] Curved rails for mining transportation are a special type of track equipment, mainly used for material transportation in mines, especially in conjunction with side-dumping mine cars, to achieve automatic and efficient unloading of materials. This makes the unloading process of mine cars more automated and efficient, reducing the labor intensity and safety risks for workers.

[0003] When using curved rails for mining transportation, the main function is to utilize the slope of the curved rails to allow side-dumping mine cars to tip over to one side for unloading. However, when the wheels of the mine cars travel uphill on the curved rails, they may shift, causing the mine cars to sway during travel. In severe cases, this can even cause the mine cars to derail, resulting in premature unloading of materials and hindering the rapid transportation of materials. Utility Model Content

[0004] This utility model addresses the problem that when mine cars travel uphill on curved tracks, the wheels may shift, causing the mine cars to sway during travel, or even detach from the tracks, resulting in premature unloading of materials and hindering rapid material transport. Therefore, this invention proposes a curved track that facilitates transportation.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a curved rail for convenient transportation, comprising a support plate, a curved rail body fixedly connected to the top of the support plate, a limiting device provided on the top of the curved rail body, the limiting device comprising two extension plates, the bottom of the two extension plates being symmetrically and fixedly connected to the top of the curved rail body, three threaded rods being uniformly threadedly connected to the inner wall of the extension plates, one end of the three threaded rods being rotatably connected to the same limiting plate, both limiting plates being disposed on the top of the curved rail body, and a protective device being provided on the outer surface of the threaded rods.

[0006] The effect achieved by the above components is as follows: by setting two limiting plates, under the action of the threaded rod, rotating the threaded rod will cause the threaded rod to extend and retract on the inner wall of the extension plate. The threaded rod will drive the limiting plates to move synchronously, thereby facilitating the adjustment of the distance between the two limiting plates according to the width of the mine car wheel. This allows the wheel width to be matched with the distance between the two limiting plates, thus limiting the wheel and preventing it from detaching from the curved rail body, which facilitates the rapid transportation of materials.

[0007] Preferably, three sliders are evenly fixedly connected to the bottom of the limiting plate, and three grooves are evenly opened on the top of the curved track body, with the outer surface of the sliders slidably connected to the inner wall of the grooves.

[0008] The effect achieved by the above components is as follows: by setting the slider and the slide groove, when the limiting plate moves under the action of the threaded rod, the limiting plate will drive the slider to slide synchronously on the inner wall of the slide groove. The slider and the slide groove can limit and guide the limiting plate.

[0009] Preferably, the outer surface of the threaded rod is threaded with two nuts, which are respectively disposed on both sides of the extension plate.

[0010] The effect achieved by the above components is as follows: by setting two nuts and rotating the two nuts respectively, so that one side of the nut abuts against one side of the extension plate, the threaded rod and the extension plate can be auxiliaryly fixed, which helps to prevent the threaded rod from rotating and causing the limiting plate to shift.

[0011] Preferably, a rubber pad is fixedly connected to one side of the nut, and the outer surface of the threaded rod is inserted into the inner wall of the rubber pad.

[0012] The effect achieved by the above components is that by setting rubber pads, the friction between the nut and the extension plate can be increased, making the nut less likely to loosen.

[0013] Preferably, one end of the threaded rod is fixedly connected to an operating block, and the outer surface of the operating block is provided with a protrusion.

[0014] The effect achieved by the above components is as follows: by setting the operating block, rotating the operating block can drive the threaded rod to rotate. At the same time, the outer surface of the operating block is provided with protrusions, which can effectively increase the friction of the outer surface of the operating block and have an anti-slip effect when rotating the operating block.

[0015] Preferably, the protective device includes a protective sleeve, the threaded rod is disposed inside the protective sleeve, and one end of the protective sleeve abuts against one side of the extension plate.

[0016] The effect achieved by the above-mentioned components is that by setting up a protective sleeve, the threaded rod can be blocked, thereby helping to prevent the threaded rod from deforming due to the direct action of external forces.

[0017] Preferably, a circular hole block is symmetrically fixedly connected to the outer surface of one end of the protective sleeve, a threaded pin is inserted into the inner wall of the circular hole block, one end of the threaded pin is fixedly connected to one side of the extension plate, and a threaded hole block is threadedly connected to the outer surface of the threaded pin.

[0018] The effect achieved by the above components is as follows: by setting a threaded pin, inserting the threaded pin into the inner wall of the round hole block, and then fitting the threaded hole block onto one end of the threaded pin, rotating the threaded hole block so that one side of the threaded hole block abuts against one side of the round hole block, the protective sleeve and the extension plate connected to the round hole block can be fixed, which helps to prevent the threaded rod from detaching from the protective sleeve.

[0019] Preferably, a U-shaped block is provided on the outer surface of the circular hole block, one side of the U-shaped block is fixedly connected to one side of the extension plate, and the outer surface of the circular hole block is inserted into the inner wall of the U-shaped block.

[0020] The effect achieved by the above components is that by setting the U-shaped block, the circular hole block can be limited, which can improve the stability of the connection between the protective sleeve and the extension plate.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting two limiting plates, the threaded rod can drive the limiting plates to move synchronously under the action of the threaded rod. This allows the distance between the two limiting plates to be adjusted according to the width of the mine car wheel, so that the width of the wheel can be matched with the distance between the two limiting plates. The two limiting plates can limit the wheel, which helps to prevent the wheel from leaving the curved rail body and facilitates the rapid transportation of materials. Attached Figure Description

[0028] Example 1, referring to Figure 1-Figure 3As shown, this embodiment discloses a curved rail for convenient transportation, including a support plate 1. A curved rail body 2 is fixedly connected to the top of the support plate 1. A limiting device 3 is provided on the top of the curved rail body 2. The limiting device 3 includes two extension plates 31. The bottoms of the two extension plates 31 are symmetrically fixedly connected to the top of the curved rail body 2. Three threaded rods 32 are evenly threaded on the inner wall of the extension plates 31. One end of the three threaded rods 32 is rotatably connected to the same limiting plate 33. Both limiting plates 33 are provided on the top of the curved rail body 2. The outer surface of the threaded rods 32 is provided with... The device 4 has a protective device. By setting two limiting plates 33, the threaded rod 32 is rotated under the action of the threaded rod 32. The threaded rod 32 will extend and retract on the inner wall of the extension plate 31. The threaded rod 32 will drive the limiting plates 33 to move synchronously. This makes it easier to adjust the distance between the two limiting plates 33 according to the width of the mine car wheel, so that the width of the wheel can match the distance between the two limiting plates 33. The two limiting plates 33 can limit the wheel, which helps to prevent the wheel from leaving the curved rail body 2 and facilitates the rapid transportation of materials.

[0029] Reference Figure 2 and Figure 3 As shown, three sliders 34 are evenly fixedly connected to the bottom of the limiting plate 33, and three grooves 35 are evenly opened on the top of the curved rail body 2. The outer surface of the slider 34 is slidably connected to the inner wall of the groove 35. By setting the sliders 34 and the grooves 35, when the limiting plate 33 moves under the action of the threaded rod 32, the limiting plate 33 will drive the sliders 34 to slide synchronously on the inner wall of the groove 35. The sliders 34 and the grooves 35 can limit and guide the limiting plate 33. Two nuts 36 are threadedly connected to the outer surface of the threaded rod 32. The two nuts 36 are respectively set on both sides of the extension plate 31. By setting the two nuts 36, rotating the two nuts 36 respectively will cause one side of the nut 36 to abut against one side of the extension plate 31, which can provide auxiliary fixation between the threaded rod 32 and the extension plate 31, which helps to prevent the limiting plate 33 from shifting due to the rotation of the threaded rod 32.

[0030] Reference Figure 2 and Figure 3 As shown, a rubber pad 37 is fixedly connected to one side of the nut 36, and the outer surface of the threaded rod 32 is inserted into the inner wall of the rubber pad 37. By setting the rubber pad 37, the friction between the nut 36 and the extension plate 31 can be increased, making the nut 36 less prone to loosening. An operating block 38 is fixedly connected to one end of the threaded rod 32. The outer surface of the operating block 38 is provided with protrusions. By setting the operating block 38, rotating the operating block 38 can drive the threaded rod 32 to rotate. At the same time, the protrusions on the outer surface of the operating block 38 can effectively increase the friction on the outer surface of the operating block 38, and have an anti-slip effect when rotating the operating block 38.

[0031] Reference Figure 2 and Figure 4 As shown, the protective device 4 includes a protective sleeve 41, and a threaded rod 32 is disposed inside the protective sleeve 41. One end of the protective sleeve 41 abuts against one side of the extension plate 31. By providing the protective sleeve 41, the threaded rod 32 can be blocked, which helps to prevent the threaded rod 32 from being deformed by the direct action of external forces.

[0032] Reference Figure 2 and Figure 4 As shown, a circular hole block 42 is symmetrically fixedly connected to the outer surface of one end of the casing 41. A threaded pin 43 is inserted into the inner wall of the circular hole block 42. One end of the threaded pin 43 is fixedly connected to one side of the extension plate 31. A threaded hole block 44 is threadedly connected to the outer surface of the threaded pin 43. By setting the threaded pin 43, the threaded pin 43 is inserted into the inner wall of the circular hole block 42, and then the threaded hole block 44 is sleeved on one end of the threaded pin 43. By rotating the threaded hole block 44, one side of the threaded hole block 44 abuts against one side of the circular hole block 42. The connection can fix the sleeve 41 connected to the circular hole block 42 and the extension plate 31, which helps to prevent the threaded rod 32 from falling off the protection of the sleeve 41. The outer surface of the circular hole block 42 is provided with a U-shaped block 45. One side of the U-shaped block 45 is fixedly connected to one side of the extension plate 31. The outer surface of the circular hole block 42 is inserted into the inner wall of the U-shaped block 45. By setting the U-shaped block 45, the circular hole block 42 can be limited, which can improve the stability of the connection between the sleeve 41 and the extension plate 31.

[0033] Working principle: Simultaneously rotating the three operating blocks 38 on one side of the extension plate 31 causes the threaded rod 32 to rotate. The threaded rod 32 extends and retracts within the inner wall of the extension plate 31. Limited by the slider 34 and the slide groove 35, the threaded rod 32 drives the limiting plate 33 to move synchronously. This allows for adjustment of the distance between the two limiting plates 33 according to the width of the mine car wheel, ensuring the wheel width matches the distance between the two limiting plates 33. Then, rotating the two nuts 36 on the outer surface of the threaded rod 32 causes the rubber pads 37 on one side of the two nuts 36 to abut against both sides of the extension plate 31, thus enabling... The threaded rod 32 and the extension plate 31 are auxiliaryly fixed to prevent the threaded rod 32 from rotating and causing the limiting plate 33 to shift. In turn, the two limiting plates 33 can limit the wheel, which helps to prevent the wheel from leaving the curved rail body 2 and facilitates the rapid transportation of materials. The threaded pin 43 is inserted into the inner wall of the round hole block 42, the round hole block 42 is inserted into the inner wall of the U-shaped block 45, and the screw hole block 44 is sleeved on one end of the threaded pin 43. The screw hole block 44 is rotated so that the rubber pad 37 on one side of the screw hole block 44 abuts against one side of the round hole block 42, which can fix the sleeve 41 connected to the round hole block 42 and the extension plate 31.
