[0036] The technical solution (including preferred technical solution) of this utility model will be further described in detail below with reference to the accompanying drawings and by listing some optional embodiments. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0037] Example 1
[0038] like Figures 1 to 3 As shown, this utility model provides a lithium-ion steel rail cutting machine, including a frame 1, a drive motor 2, a cutting component 3, a switch handle 5, a power battery pack 6, and a swing frame 10.
[0039] The drive motor 2 is fixedly mounted on the frame 1, and the cutting component 3 is connected to the drive motor 2 via the connecting bracket 4. A switch handle 5 is mounted on the frame 1 to control the start and stop of the cutter. The power battery pack 6 is fixed to the frame 1 via the battery pack bracket 7 and is located above the drive motor 2, providing power to the drive motor 2. The output end of the drive motor 2 is connected to the saw blade 9 of the cutting component 3 via the transmission mechanism 8, driving the saw blade 9 to cut the steel rail. One end of the swing frame 10 is detachably and rotatably connected to the connecting bracket 4, and the other end is clamped onto the steel rail, used to fix the cutter to the steel rail.
[0040] In this embodiment, the drive motor 2 is a brushless DC motor, which features high efficiency and low noise, with a rated power of 9000W, sufficient to meet the power requirements for rail cutting. The power battery pack 6 uses a lithium-ion battery pack with a voltage of 72V and a capacity of 10Ah, which can operate continuously for about 2 hours under normal use, meeting the needs of most railway maintenance operations.
[0041] The cutting component 3 includes a cutting arm and a saw blade 9. The cutting arm is connected to the drive motor 2 via a connecting frame 4. The saw blade 9 is a diamond cutting disc with a diameter of 400mm and a cutting thickness of 4mm, capable of effectively cutting steel rails of various specifications. The transmission mechanism 8 adopts a gear transmission structure or a belt transmission structure to transmit the rotational motion of the drive motor 2 to the saw blade 9, achieving efficient cutting.
[0042] The switch handle 5 integrates the control switch of the cutting machine. Operators can start or stop the cutting machine by holding the switch handle 5 and pressing the control button. This design makes operation safer and more convenient, avoiding the possibility of misoperation.
[0043] Example 2
[0044] like Figures 4 to 6 As shown, in this embodiment, the swing frame 10 includes an upper support arm 11 and a lower support arm 12. One end of the upper support arm 11 is detachably connected to the connecting frame 4, and the other end is rotatably connected to one end of the lower support arm 12. The other end of the lower support arm 12 is rotatably connected to a rail fixing seat 13. The rail fixing seat 13 is provided with a position locking mechanism 14 for locking the angle between the lower support arm 12 and the rail fixing seat 13, and a clamping mechanism 15 for clamping the rail.
[0045] The upper support arm 11 is made of high-strength aluminum alloy, which is lightweight and strong, and easy to operate. The lower support arm 12 is also made of the same material. The upper support arm 11 and the lower support arm 12 are connected by a hinge, and the angle can be adjusted according to actual needs to adapt to different working environments.
[0046] The position locking mechanism 14 is used to lock the included angle between the lower support arm 12 and the rail fixing seat 13, so that the cutting machine remains stable during operation. The clamping mechanism 15 is used to firmly clamp the rail fixing seat 13 onto the rail to prevent shaking or falling off during the cutting process.
[0047] Example 3
[0048] like Figures 4 to 6 As shown, in this embodiment, the position locking mechanism 14 includes a position fixing plate 16 fixed to the lower support arm 12, and the position fixing plate 16 is provided with a plurality of locking holes spaced apart. The locking mechanism 14 also includes a locking seat 18 fixed to the rail fixing seat 13, and the locking seat 18 is provided with a movable pin 19. By inserting the movable pin 19 into different locking holes, different included angles between the lower support arm 12 and the rail fixing seat 13 can be locked.
[0049] The position fixing plate 16 is made of 5mm thick steel plate, with 8 locking holes 17 evenly distributed on it. The arrangement of these locking holes 17 allows the lower support arm 12 and the rail fixing seat 13 to form different angles such as 0°, 15°, 30°, 45°, 60°, 75°, 90° and 105° to meet different cutting requirements.
[0050] The locking seat 18 is fixed to the rail fixing seat 13 and is made of cast iron, which has good strength. The movable pin 19 is made of high-strength stainless steel with a diameter of 7.8mm. One end is connected to a spring so that it can automatically return to its original position, and the other end is equipped with a handle for easy insertion and removal by the operator.
[0051] This design allows operators to quickly adjust the working angle of the cutting machine according to actual needs, improving work efficiency and flexibility. At the same time, the tight fit between the movable pin 19 and the locking hole 17 ensures stability and safety during operation.
[0052] Example 4
[0053] like Figure 5As shown, in this embodiment, the clamping mechanism 15 includes an opening slot 20 at the bottom of the rail fixing seat 13. One inner wall of the opening slot 20 is a vertical surface 21, and the opposite inner wall is an inclined surface 22 extending towards the vertical surface 21. A T-shaped screw 23 is provided on the side of the rail fixing seat 13 with the vertical surface 21. The vertical surface 21 fits against the upper inner wall of the rail, and the inclined surface 22 engages with the outer wall of the rail. Rotating the T-shaped screw 23 causes its end to abut against the rail, thereby clamping the rail.
[0054] The angle between the vertical plane 21 and the inclined plane 22 is 65°. This angle design allows the clamping mechanism 15 to automatically adapt to rails of different specifications, improving the versatility of the equipment.
[0055] The T-screw 23 is made of high-strength alloy steel with a diameter of 16mm and has undergone surface hardening treatment to improve wear resistance and service life. The T-shaped handle of the T-screw 23 is 120mm long, providing sufficient lever arm to allow operators to easily lock and release the clamping mechanism 15.
[0056] This clamping mechanism 15 features a simple structure and convenient operation, firmly securing the cutting machine to the rails and ensuring stability and safety during the cutting process. Furthermore, its snap-fit design makes installation and disassembly extremely convenient, significantly improving work efficiency.
[0057] Example 5
[0058] like Figure 4 and Figure 6 As shown, in this embodiment, a rotating shaft 24 is rotatably connected to the swing frame 10. One end of the rotating shaft 24 is provided with a handle 25, and the other end passes through the swing frame 10 and is detachably connected to the connecting frame 4 by threads.
[0059] The pivot 24 is made of 12mm diameter stainless steel with a precision-machined surface to ensure excellent rotational performance. The handle 25 is covered with rubber, providing a comfortable grip and anti-slip effect. The pivot 24 is connected to the swing frame 10 via bearings, ensuring smooth rotation and durability.
[0060] After passing through the swing frame 10, the rotating shaft 24 is connected to the connecting frame 4 via threads. This design allows the cutting machine to be quickly separated from the swing frame 10 when needed, facilitating transportation and storage. At the same time, the threaded connection provides sufficient strength to ensure stability and safety during operation.
[0061] By rotating the handle 25, the operator can adjust the angle and position of the cutter to adapt to different cutting needs, thus improving the flexibility and applicability of the equipment.
[0062] Example 6
[0063] like Figure 1 and Figure 2 As shown, in this embodiment, the rail cutting machine also includes an auxiliary handle 26. One end of the auxiliary handle 26 is fixed to the bottom of the battery pack bracket 7, and the other end is wrapped around the top of the power battery pack 6.
[0064] The auxiliary handle 26 is made of bent steel tubing with a plastic coating, providing a comfortable grip and a non-slip surface. The design of the auxiliary handle 26 fully considers ergonomic principles, allowing operators to maintain a comfortable posture and reduce fatigue when carrying equipment.
[0065] The auxiliary handle 26 is bolted to the battery pack bracket 7, ensuring sufficient strength. The auxiliary handle 26, designed to bypass the top of the power battery pack 6, forms a protective frame, facilitating equipment handling and protecting the power battery pack 6 from collision damage.
[0066] The design of this auxiliary handle 26 makes it easier to move the equipment, especially in the field environment of railway maintenance, which greatly reduces the labor intensity of operators and improves work efficiency.
[0067] Example 7
[0068] In this embodiment, a handle connecting plate 27 is fixed between the battery pack bracket 7 and the drive motor 2. One end of the auxiliary handle 26 passes over the top of the power battery pack 6 and wraps around to the bottom of the battery pack frame, where it is fixed to the handle connecting plate 27.
[0069] The handle connecting plate 27 is made of steel plate. The handle connecting plate 27 is fixedly connected to the battery pack bracket 7 and the drive motor 2 by bolts, forming a stable support structure.
[0070] The auxiliary handle 26 is bolted to the handle connecting plate 27, ensuring sufficient strength. This design makes the auxiliary handle 26, handle connecting plate 27, battery pack bracket 7 and drive motor 2 form a whole structure, improving the rigidity and stability of the entire device.
[0071] This structural design not only facilitates equipment handling but also enhances the overall strength of the equipment and extends its service life. Furthermore, the presence of the handle connecting plate 27 reduces the risk of deformation during transport, thus improving safety.
[0072] Example 8
[0073] like Figure 3As shown, in this embodiment, the design of the cutting component 3 is further optimized. The cutting component 3 includes a cutting arm, a saw blade 9, and a protective cover. The cutting arm is made of high-strength aluminum alloy, which is lightweight and high-strength. The saw blade 9 is a diamond cutting blade with a diameter of 450mm, a cutting thickness of 4mm, and a rotation speed of 4500rpm, which can efficiently cut rails of various specifications.
[0074] The protective cover is made of steel plate and covers most of the area of the saw blade 9, leaving only the necessary cutting opening, which greatly improves the safety of operation.
[0075] One end of the connecting frame 4 is fixed to the output end of the drive motor 2, and the other end is rotatably connected to the cutting component 3; the drive motor 2 drives the saw blade 9 to rotate via belt drive, thereby cutting the steel rail. A swing frame connecting sleeve 28 is provided in the middle of the connecting frame 4. The rotating shaft 24 is screwed into the swing frame connecting sleeve 28 via the handle 25.
[0076] Those skilled in the art will readily understand that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, combinations, substitutions, improvements, etc., made under the spirit and principles of the present utility model are included within the protection scope of the present utility model.
