For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0024] See Figures 1-3 and combined Figure 4 The internal combustion concrete sleeper bolt drilling machine of this application has a main structure including a power mechanism, a support mechanism and a positioning mechanism. The power mechanism includes a gasoline engine 1 and a reduction gearbox assembly 2. The reduction gearbox assembly 2 is connected to an output shaft 3. The output shaft 3 is connected to an output shaft gear 31. The gasoline engine 1 is connected to a gasoline engine gear shaft 11. An intermediate transmission assembly 4 is provided between the gasoline engine gear shaft 11 and the output shaft gear 31. The intermediate transmission assembly is used to transmit the output torque of the gasoline engine 1 to the output shaft 3.

[0025] The intermediate transmission assembly 4 outputs the torque of the gasoline engine 1 and transmits it to the output shaft 3, enabling the drilling rig to have sufficient power.

[0026] The gasoline engine 1 is connected to the gasoline engine gear shaft 11 via a clutch, serving as the power source. The gasoline engine 1 transmits power to the reduction gearbox assembly 2 via the gasoline engine gear shaft 11, and then the intermediate transmission assembly 4 transmits the torque to the output shaft 3. The output shaft 3 drives the drill bit to rotate, effectively drilling concrete sleeper bolts and nylon sleeves. The gear transmission through the intermediate transmission assembly 4 ensures smooth transmission, a compact structure, and guarantees drilling power. It is accurate, reliable, and occupies little space.

[0027] From the perspective of transmission, in one specific embodiment, the intermediate transmission component 4 specifically includes an intermediate gear shaft 41 and an intermediate transmission gear 42. The bottom of the intermediate gear shaft 41 is connected to an intermediate cylindrical gear 43, and the intermediate transmission gear 42 is connected to the top of the intermediate gear shaft 41.

[0028] Furthermore, the intermediate cylindrical gear 43 is meshed with the output shaft gear 31, and the bottom of the gasoline engine gear shaft 11 is connected to the gasoline engine cylindrical gear 12, with the intermediate transmission gear 42 meshing with the gasoline engine cylindrical gear 12.

[0029] Through the meshing relationship of the aforementioned gear shaft, transmission gear, and cylindrical gear, the output torque of the gasoline engine 1 can be effectively transmitted to the output shaft 3 to form a complete power transmission chain.

[0030] The gearbox assembly 2 includes a gearbox housing 21, a gasoline engine gear shaft 11, an intermediate transmission assembly 4, and an output shaft gear 31, all of which are installed inside the gearbox housing 21.

[0031] To ensure stable and reliable rotation of the transmission components within the gearbox assembly 2, the gasoline engine gear shaft 11 is installed inside the gearbox housing 21 via multiple deep groove ball bearings 22. The multiple deep groove ball bearings 22 are arranged in sequence along the axial direction of the gasoline engine gear shaft 11 and are fixed to the gasoline engine gear shaft 11 by clamps.

[0032] Meanwhile, the output shaft 3 and the intermediate gear shaft 41 are respectively installed in the gearbox housing 21 by deep groove ball bearings 22. The deep groove ball bearings 22 on the output shaft 3 are set on the top and bottom sides of the output shaft gear 31, and the deep groove ball bearings 22 on the intermediate gear shaft 41 are set on the top and bottom ends of the intermediate gear shaft 41.

[0033] Furthermore, by clamping the inner circle of the deep groove ball bearing 22 to the gasoline engine gear shaft 11, output shaft 3 and intermediate gear shaft 41, and fixing the outer circle inside the gearbox housing 21, the smooth rotation of each shaft can be ensured, thereby ensuring the reliable transmission and output of the gasoline engine 1's output torque.

[0034] From the perspective of the specific composition of the gearbox housing 21, the gearbox housing 21 includes a gearbox upper cover 21a, a gearbox middle shell 21b, and a gearbox lower cover 21c, which can form an effective installation space for the transmission mechanism and ensure the compactness of the structural layout.

[0035] An output shaft cover 32 is provided between the output shaft 3 and the gearbox housing 21. The output shaft cover 32 is specifically installed at the bottom of the gearbox housing 21 to allow the output shaft 3 to pass through. At the same time, a water inlet connector 33 is connected to the output shaft cover 32. The water inlet connector 33 is detachably connected to the output shaft cover 32 by threads, forming a quick-release water inlet connector 33. During operation, the water inlet connector 33 is connected to the pressure vessel water tank through a hose, and water is injected simultaneously during drilling to solve the problem of heat dissipation of the drill bit.

[0036] The internal combustion concrete sleeper bolt drilling machine of this utility model is specifically a dual-purpose drilling machine, capable of drilling and removing nylon sleeves on sleepers and removing failed bolts.

[0037] In the prior art, drilling for nylon sleeves and bolts is carried out by different drilling machines. However, the internal combustion concrete sleeper bolt drilling machine of this utility model can realize the drilling operation of nylon sleeves and bolts by detachably connecting the drill bit to the output shaft 3.

[0038] Specifically, a drill bit is connected to the output shaft 3. The drill bit includes a nylon sleeve drill bit (not shown in the figure) and a diamond anchor drill bit 5. The nylon sleeve drill bit and the diamond anchor drill bit 5 are detachably connected to the output shaft 3.

[0039] The nylon sleeve drilling bit is specifically a hollow drill bit designed for nylon sleeves, used to drill through nylon sleeves on railway sleepers.

[0040] The diamond anchoring drill bit 5 is a solid diamond alloy drill bit that can be used to re-anchor concrete sleepers after they have been disassembled and replaced.

[0041] At the connection and installation angle of the drill bit, the bottom end of the output shaft 3 is provided with a threaded connecting cone 34. When connecting the diamond anchor drill bit 5, an adapter is threaded onto the connecting cone 34, and the diamond anchor drill bit 5 is connected to the adapter. The diamond anchor drill bit 5 and the adapter are then fastened together, thus completing the detachable installation of the diamond anchor drill bit 5 on the output shaft 3.

[0042] When connecting the nylon sleeve drill bit, an extension rod 35 is threaded onto the connecting cone 34, and the nylon sleeve drill bit is connected to the extension rod 35. The extension rod 35 is then fastened to the nylon sleeve drill bit with bolts, thus completing the detachable installation of the nylon sleeve drill bit on the output shaft 3.

[0043] Through the different connection methods described above, a tight and stable connection can be formed, so that the drill bit is effectively connected to the output shaft 3 and is not easy to loosen, which is safe and reliable.

[0044] The nylon-sheathed drill bit is made of cemented carbide, offering excellent hardness and wear resistance, and high cutting efficiency. The diamond anchoring drill bit 5 can also effectively remove metal bolts, ensuring reliable re-anchoring of failed bolts to concrete sleepers.

[0045] In terms of the overall structure of the drilling machine, the internal combustion concrete sleeper bolt drilling machine of this utility model also includes a positioning base 6, a support mechanism and a sliding bracket 8. The positioning base 6 is mainly used for counterweight, and the support mechanism is specifically used to support the power mechanism.

[0046] The gasoline engine 1 is connected to the top of the gearbox assembly 2. The gearbox assembly 2 is connected to the sliding bracket 8. The support mechanism includes a support column 7 connected to the positioning base 6. The sliding bracket 8 is vertically connected to the support column 7 via a gear and rack mechanism.

[0047] The gear and rack mechanism includes a lifting gear and a fixed rack 71 that are meshed together. The fixed rack 71 is mounted on the support column 7. The sliding bracket 8 is connected to a lifting control shaft 81 and a lifting rocker arm 82. The lifting control shaft 81 passes through the sliding bracket 8. The lifting gear is installed inside the sliding bracket 8 and connected to the lifting control shaft 81.

[0048] By rotating the lifting rocker arm 82, the lifting control shaft 81 can be rotated, which can control the lifting gear to rotate synchronously. Combined with the meshing connection between the lifting gear and the fixed rack 71, the sliding bracket 8 can drive the reduction gearbox assembly 2 and the gasoline engine 1 to lift.

[0049] The positioning base 6 includes a positioning base plate 61 and a support base 62, which acts as a counterweight to support the weight of the entire machine and allows for the installation of rail clamps 64. Support columns 7 are mounted on the support base 62. A pair of through-tubes 63 are arranged on the positioning base plate 61, and rail clamps 64 are inserted into the through-tubes 63. The rail clamp 64 includes a Z-shaped positioning rod 65, and the extended end of the positioning rod 65 is provided with a vertically positioned positioning bolt 66 that can abut against the bottom surface of the rail from bottom to top. A positioning handle 67 is connected to the positioning base 6.

[0050] During operation, by extending the positioning rod 65 into the bottom of the rail and pushing the positioning bolt 66 upward from the bottom to abut against the bottom surface of the rail, and by pressing down the positioning handle 67 on the other side of the support column 7, the positioning base 6 can be effectively fixed, ensuring the stability of the power mechanism in drilling operations.

[0051] When the equipment is in operation, the person stands on the through-tube 63 of the positioning base plate 61 to prevent the equipment from moving during operation, and disassembly and installation are flexible and convenient.

[0052] The internal combustion concrete sleeper bolt drilling machine of this utility model uses an internal combustion gasoline engine as a power source. It has the advantages of light weight, high speed, low cost, large power, sufficient power, convenient maintenance, and strong economic applicability.

[0053] The gasoline engine, via a clutch and gearbox, drives the nylon-shrouded drill bit or diamond-modified anchor drill bit to achieve ideal drilling operations.

[0054] It can be used to convert concrete sleepers to anchor tracks and also to drill for nylon sleeves on high-speed turnouts. Based on track maintenance needs, the rail clamps are fixedly installed under the sleepers, and the positioning bolts are tightened until the equipment is secure. After installing the appropriate drill bit and connecting the cooling water tank, work can begin. Manually rotating the crank drives the lifting gear, and the gear and rack meshing transmission achieves the lifting and lowering movement of the drilling machine.

[0055] The internal combustion concrete sleeper bolt drilling machine of this utility model does not require an external power source or power source. It can be powered by a gasoline engine. It can perform fault repair without the need for train repair or shutdown. It is easy for workers to carry, occupies little space, has low cost, high work efficiency, low repair risk, and high safety.
