[0001] This utility model relates to the field of tool anchor disassembly technology, specifically to a wooden sleeper drilling device. Background Technology

[0002] On coal-dedicated railways, diesel engine wrenches are commonly used for tightening and loosening sleeper bolts. Sleeper replacement is mostly done using electric drills, requiring on-site power supplies such as generators, and necessitates the collaboration of multiple personnel. This presents challenges such as complex processes, a large workforce, high labor intensity, and inconvenient transportation. Furthermore, the use of electric drills carries the safety risk of accidental electric shock.

[0003] Therefore, the existing technology needs further improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, a wooden sleeper drilling device is proposed, which solves the problems of complex processes, large number of workers, high labor intensity, and inconvenient transportation associated with the use of electric drills for wooden sleeper replacement.

[0005] To achieve the above objectives, the present invention proposes the following technologies:

[0006] A drilling device for wooden sleepers includes a connecting component located at the output end of a driving component and detachably connected to the driving component. A drill bit is embedded at the end of the connecting component away from the driving component. The driving component drives the drill bit to rotate to perform drilling through the connecting component.

[0007] Furthermore, the connection component includes a converter head, with a first connection slot for connecting the output end of the drive component and a second connection slot for connecting the drill bit at both ends.

[0008] Furthermore, the converter head is frustum-shaped, the first connecting groove is located at the end of the converter head with a smaller diameter, and the second connecting groove is arranged opposite to the first connecting groove.

[0009] Furthermore, the output end of the drive component is specifically a plug that matches the shape of the first connection slot. The plug is inserted into the first connection slot to connect the drive component and the adapter.

[0010] Furthermore, the connecting assembly also includes a limiting pin that passes through the adapter head, and the corresponding adapter head has a limiting hole that communicates with the first connecting groove, and the plug has a through hole for the limiting pin to be inserted.

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] In this document, terms such as “up,” “down,” “left,” “right,” and “top” indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element 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.

[0022] like Figures 1 to 3 As shown, a wooden sleeper drilling device includes a connecting component located at the output end of a driving component and detachably connected to the driving component. A drill bit 1 is embedded at the end of the connecting component away from the driving component. The driving component drives the drill bit 1 to rotate and drill through the connecting component.

[0023] By setting up a connecting component, it is easy to connect the drive component to install the drill bit 1. The connecting component enables the rapid assembly of the drill bit 1 and the drive component. Only one person is needed to complete the drilling operation for replacing wooden sleepers and the tightening and loosening of railway line bolts, thus solving the problems of high manpower requirements and low drilling efficiency in wooden sleeper drilling operations. Furthermore, it eliminates the need for power supply facilities such as generators, reducing labor intensity and the risk of electric shock. It has good promotion and application value in the drilling operation of wooden sleepers on coal-dedicated railways.

[0024] In the wooden sleeper drilling device of this embodiment, the connecting component includes a converter head 2, and the two ends of the converter head 2 are respectively provided with a first connecting groove 3 for connecting the output end of the drive component and a second connecting groove 4 for connecting the drill bit 1.

[0025] Specifically, in this embodiment, the driving component is an internal combustion engine wrench. The connecting slots at both ends of the adapter 2 are connected to the internal combustion engine wrench and the drill bit 1, respectively. This is equivalent to the drill bit 1 being directly connected to the internal combustion engine wrench, which facilitates drilling operations by a single person and solves the problems of high personnel occupation and low drilling efficiency in wooden sleeper drilling operations.

[0026] In the wooden sleeper drilling device of this embodiment, the conversion head 2 is frustum-shaped, the first connecting groove 3 is located at the end of the conversion head 2 with a smaller diameter, and the second connecting groove 4 is arranged opposite to the first connecting groove 3.

[0027] The above configuration allows the adapter head on one side of the drill bit 1 to have a thicker wall, matching the tapered shank of the drill bit 1. This indirectly increases the size of the smaller-diameter drill bit 1, improving the stability of the adapter head 2 when it is rotated by the internal combustion engine wrench. This, in turn, improves the stability of the drill bit 1 rotating and drilling, ensuring normal drilling operations.

[0028] Specifically, the internal combustion engine wrench uses a small gasoline engine as its power source.

[0029] Preferably, the converter head 2 is made of carbon steel, and the outer dimensions of the frustum are φ45mm at the top and φ55mm at the bottom.

[0030] In the wooden sleeper drilling device of this embodiment, the output end of the drive component is specifically a plug that matches the shape of the first connecting slot 3. The plug is inserted into the first connecting slot 3 to realize the connection between the drive component and the conversion head 2.

[0031] Specifically, the first connecting groove 3 is polygonal in shape. The above-mentioned setting enables the installation of the adapter 2 and the internal combustion engine wrench, and limits the adapter 2 in the circumferential direction, so that the adapter 2 can be driven to rotate by the internal combustion engine wrench.

[0032] In the wooden sleeper drilling device of this embodiment, the connecting component further includes a limiting pin that passes through the conversion head 2. The corresponding conversion head 2 is provided with a limiting hole 5 that communicates with the first connecting groove 3. The plug is provided with a through hole for the limiting pin to be inserted.

[0033] With the above settings, after the adapter 2 is installed with the plug through the first connecting groove 3, the limiting pin is inserted into the limiting hole 5 and passes through the through hole on the plug to achieve axial positioning of the adapter 2 and the internal combustion engine wrench, thus preventing the adapter 2 from detaching.

[0034] Preferably, the first connecting groove 3 is a concave quadrangular design with an inner diameter of 39mm, which is connected to the head of the internal combustion engine bolt wrench; the head is provided with a pin hole, into which a pin can be inserted to fix the adapter 2 and prevent it from falling off.

[0035] In the wooden sleeper drilling device of this embodiment, the drill bit 1 is specifically a tapered shank drill bit with a tapered end. The shape of the second connecting groove 4 matches the shape of the tapered shank 6 of the tapered shank drill bit. The tapered shank 6 is inserted into the conversion head 2 to realize the embedding and installation of the drill bit 1.

[0036] Specifically, the above settings enable the installation of drill bit 1 and adapter head 2. A tapered shank drill bit is selected, and its tapered design provides better clamping force, effectively preventing drill bit 1 from slipping off during high-speed rotation, thereby improving working stability. The shank of the tapered shank drill bit has a certain taper, which is inserted into the tapered hole of adapter head 2, thereby improving the rigidity and concentricity of drill bit 1, reducing offset and vibration, and improving drilling accuracy.

[0037] By equipping the internal combustion engine wrench with a special tapered shank adapter 2 and a tapered shank drill bit, only one person is needed to complete the drilling operation of the wooden sleeper. This effectively solves the problems of the wooden sleeper replacement operation, which requires a large number of personnel, is labor-intensive, has a complex process, is inconvenient to transport, and poses a safety risk of electric shock to personnel. It is suitable for auxiliary devices for drilling railway wooden sleepers.

[0038] In the wooden sleeper drilling device of this embodiment, the second connecting groove 6 includes a first conical groove 7 and a second conical groove 8. The second conical groove 8 is located at one end of the first conical groove 7 near the first connecting groove 3. The upper and lower walls of the second conical groove 8 gradually approach each other to match the shape of the end of the cone handle 6.

[0039] Specifically, the first conical groove 7 has a small inclination angle, which facilitates the insertion of the conical shank drill bit 1. The upper and lower walls of the second conical groove 8 are arc-shaped and protrude inward to match the shape of the end of the conical shank 6. Through the above settings, the shape of the second connecting groove 6 is matched with the shape of the conical shank part of the drill bit 1, thereby achieving effective fixed installation of the drill bit 1 and ensuring that the adapter 2 drives the drill bit 1 to rotate stably for drilling operations.

[0040] Specifically, the other end of the adapter 2 adopts an embedded design as a tapered shank drill bit magazine, into which φ28mm tapered shank drill bits can be inserted.

[0041] In the wooden sleeper drilling device of this embodiment, the conversion head 2 is also provided with a retraction cone hole 9. The retraction cone hole 9 is connected to the second connecting groove 4 and intersects with the end of the second conical groove 8, so that the end of the triangular iron inserted into the retraction cone hole 9 abuts against the end of the cone handle 6.

[0042] The tapered hole 9 is provided to facilitate the disassembly of drill bit 1 and adapter head 2. A triangular disassembly device with a bevel is inserted into the tapered hole 9, so that the inclined surface of the pointed part of the triangular iron abuts against the end part of the cone shank 6 in the second conical groove 8, and the triangular iron is struck. Through the feeding of the triangular iron along the tapered hole 9, and through the cooperation between the inclined surface of the triangular iron and the end face of the cone shank 6, the cone shank 6 and drill bit 1 are pushed out of the second connecting groove 4, thereby realizing the disassembly of drill bit 1.
