[0027] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0028] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.
[0029] like Figure 1 As shown, the drilling machine of this utility model includes a frame 1, a clamping mechanism, a drilling machine body, and a feeding mechanism.
[0030] The clamping mechanism is mounted on the frame 1. When the drilling machine is drilling, the clamping mechanism works with the frame 1 to stably fix the drilling machine on the rail.
[0031] Specifically, such as Figures 1-3 As shown, the frame 1 is equipped with a first gripper 11 adapted to the rail. The clamping mechanism includes a clamping member 21, which is slidably mounted on the frame 1 in the front-rear direction. The clamping member 21 is equipped with a second gripper 211 adapted to the rail, the position of which corresponds to the position of the first gripper 11. The clamping member 21 has a clamping position and a releasing position. When the clamping member 21 slides relative to the frame 1 to the clamping position, the second gripper 211 approaches the first gripper 11, such as... Figure 1 As shown. When the clamping member 21 is in the released position, the second jaw 211 moves away from the first jaw 11.
[0032] Specifically, the rail has an "I"-shaped structure, including a rail head at the top, a rail web in the middle, and a rail base at the bottom. The first clamp 11 has a first abutment portion 111 adapted to the rail head and rail web on one side of the rail, and the second clamp 211 has a second abutment portion 2111 adapted to the rail head and rail web on the other side of the rail. When the rail is clamped by the clamping mechanism, the first abutment portion 111 abuts against the lower side of the rail head and the side of the rail web on one side of the rail, and the second abutment portion 2111 abuts against the lower side of the rail head and the side of the rail web on the other side of the rail. When the drilling machine is fixed to the rail by the clamping mechanism, because the first clamp 11 and the second clamp 211 are adapted to the profile of the rail, they can better fit the rail, thus making the drilling machine more stable and less prone to shaking during drilling.
[0033] First abutment parts 111 are respectively disposed on opposite sides of the first gripper 11, and the specifications of the first abutment parts 111 on both sides are different. Second abutment parts 2111 are respectively disposed on opposite sides of the second gripper 211, and the specifications of the second abutment parts 2111 on both sides are different. For example, the first abutment parts 111 and the second abutment parts 2111 on one side are adapted to 60 rails, and the first abutment parts 111 and the second abutment parts 2111 on the other side are adapted to 50 rails. The first gripper 11 is detachably and can be installed in both directions on the frame 1, and the second gripper 211 is detachably and can be installed in both directions on the clamping member 21. In this way, the installation direction of the first gripper 11 and the second gripper 211 can be selected according to the application, making the drilling machine suitable for drilling various specifications of rails, thus improving the applicability of the drilling machine.
[0034] The clamping mechanism also includes a drive assembly for driving the clamping member 21 to slide back and forth relative to the frame 1. Figure 1 As shown, the drive assembly includes a handle 22 and a first connecting rod 23. The handle 22 is rotatably mounted on the frame 1, one end of the first connecting rod 23 is rotatably connected to the handle 22, and the other end of the first connecting rod 23 is rotatably connected to the clamping member 21. Thus, a crank-slider mechanism is formed between the frame 1, the clamping member 21, the first connecting rod 23, and the handle 22. When the handle 22 rotates, the clamping member 21 can be driven to slide relative to the frame 1 via the first connecting rod 23.
[0035] In this embodiment, the handle 22 includes an operating part 221 and a connecting part 222 integrally formed at one end. The rotatable connection between the handle 22 and the first connecting rod 23 is located at the intersection of the operating part 221 and the connecting part 222. The rotatable connection between the handle 22 and the frame 1 is located at the end of the connecting part 222 away from the operating part 221. The length of the operating part 221 is greater than the length of the connecting part 222. When the handle 22 is rotated downward, the clamping member 21 slides relative to the frame 1 towards the clamping position. When the handle 22 is rotated upward, the clamping member 21 slides relative to the frame 1 towards the release position. This structure of the handle 22 makes it easy and effortless to use the clamping mechanism to clamp the rail when operating the handle 22.
[0036] The drilling machine also includes a guiding mechanism for guiding the back-and-forth sliding of the clamping member 21. The guiding mechanism includes a guide post 12 fixedly disposed on one of the frame 1 and the clamping member 21, and a guide sleeve 212 disposed on the other. The guide sleeve 212 is fitted over the guide post 12, and the guide post 12 and the guide sleeve 212 can slide relative to each other in the back-and-forth direction. In this embodiment, the guide post 12 is disposed on the frame 1, and the guide sleeve 212 is disposed on the clamping member 21.
[0037] like Figure 1 and Figure 4 As shown, the drilling machine body includes a power mechanism 31, a gearbox 32, and a drill bit. The gearbox 32 has an output shaft 321 that extends in the front-to-back direction. The power mechanism 21 is mounted on the gearbox 22 to drive the output shaft 321 to rotate. The drill bit is mounted on the output shaft 321, and the central axis of the drill bit also extends in the front-to-back direction, thereby driving the drill bit to rotate synchronously around its central axis when the output shaft 321 rotates.
[0038] The power mechanism 31 uses a gasoline engine, which avoids the problems of existing electric drive mechanisms requiring a fixed power supply and being limited in operation in areas without electricity, such as the field or tunnels. In addition, when drilling high-hardness steel rails, electric drive mechanisms are prone to jamming or accelerated drill bit wear due to insufficient power, have poor load adaptability, and cause the motor to overheat during continuous operation, requiring frequent shutdowns for cooling, which affects efficiency.
[0039] The drill bit can be directly connected to the output shaft 321 of the gearbox 32. Alternatively, it can be mounted on the output shaft 321 via an extension rod. The extension rod extends the length of the drill bit, allowing it to reach deeper positions and thus expanding the drilling range.
[0040] The drill bit can be detachably connected to the output shaft 321 or the extension rod via a self-locking chuck, allowing for easy replacement of different sized drill bits to meet operational needs. The self-locking chuck method for changing drill bits is simple and quick. The self-locking connector can utilize existing technologies.
[0041] The feed mechanism is mounted on the frame 1. The feed mechanism is used to drive the drilling machine body to slide relative to the frame 1 in the front-to-back direction so as to feed the drill bit during drilling.
[0042] The feeding mechanism includes a lead screw mechanism and a connecting rod assembly. One end of the connecting rod assembly is movably connected to the lead screw mechanism, and the other end of the connecting rod assembly is movably connected to the drilling machine body.
[0043] like Figure 1 As shown, the lead screw mechanism includes a lead screw 41, a slide bar 42, and a handwheel 43. The lead screw 41 extends in the front-to-back direction and is rotatably mounted on the frame 1 around its own axis. The handwheel 43 is fixedly connected to the lead screw 41, so that rotating the handwheel 43 drives the lead screw 41 to rotate around its own axis. The slide bar 42 is threadedly engaged with the lead screw 41, so that when the lead screw 41 rotates around its own axis, it drives the slide bar 42 to slide relative to the frame 1 in the front-to-back direction.
[0044] The linkage assembly includes a second link 44 and a third link 45. One end of the second link 44 is rotatably connected to the slide bar 42, and the other end of the second link 44 is rotatably connected to the third link 45 via a first shaft 46. The third link 45 is rotatably mounted on the frame 1 about a second shaft 47, and the other end of the third link 45 is rotatably connected to the drilling machine body via a third shaft 48.
[0045] Thus, when the slide bar 42 slides relative to the frame 1 in the front-back direction, the second link 44 pulls the third link 45 to rotate relative to the frame 1 around the second axis 47. When the third link 45 rotates, it drives the drilling machine body to slide relative to the frame 1 in the front-back direction.
[0046] In this embodiment, on the third link 45, the first shaft 46 and the third shaft 48 are located on the upper and lower sides of the second shaft 47, respectively.
[0047] The other end of the third link 45 is provided with a first slide groove 451, and the third shaft 48 is rotatable and slidable in the first slide groove 451 along the extension direction of the first slide groove 451.
[0048] In this embodiment, the third shaft 48 is fixedly mounted on the gearbox 32, and the frame 1 is provided with a second slide groove 13 extending in the front-back direction. The third shaft 48 is slidably mounted in the second slide groove 13 along the extension direction of the second slide groove 13.
[0049] The frame 1 is also provided with a third slide groove 14 extending in the front-to-back direction, and the slide rod 42 is slidably disposed in the third slide groove 14 along the extension direction of the third slide groove 14.
[0050] When the handwheel 43 is turned, it drives the slide bar 42 to slide backward along the third slide groove 14 via the lead screw 41. The third shaft 48 can then slide forward along the second slide groove 13, causing the entire drilling machine body to slide forward. Conversely, when the handwheel 43 is turned in the opposite direction, it drives the slide bar 42 to slide forward along the third slide groove 14 via the lead screw 41. The third shaft 48 can then slide backward along the second slide groove 13, causing the entire drilling machine body to slide backward.
[0051] The operating method of this drilling machine is as follows:
[0052] Move the entire drilling machine to the rail position, adjust its position so that the drill bit is aligned with the drilling location, and engage the first gripper 11 on one side of the rail. Turn the handle 22 downwards to slide the clamping member 21 relative to the frame 1 towards the clamping position until the clamping member 21 moves to the other side where the second gripper 211 engages with the rail, thus fixing the drilling machine to the rail. Start the gasoline engine, transmitting power to the drill bit through the gearbox 22 to make it rotate. Turn the handwheel 43 to drive the slide bar 42 to slide relative to the frame 1 via the lead screw 41, which in turn drives the third link 45 to rotate around the second shaft 47 relative to the frame 1 via the second link 44. When the third link 45 rotates, it causes the entire drilling machine body to slide back and forth relative to the frame 1 to perform the drilling operation.
[0053] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
