[0026] The present application is further described in detail below in conjunction with all the drawings and specific embodiments.

[0027] Reference Figure 1 The present invention provides a manual drilling machine for use in railway construction to manually drill holes in rails. The manual drilling machine comprises a frame 1, a rotating shaft 2, and a drill bit 3. The frame 1 can be erected and stably fixed on a rail. The drill bit 3 is fixed to one end of the rotating shaft 2. Rotating and moving the rotating shaft 2 drives the drill bit 3 to rotate and feed, thereby drilling holes in the rail.

[0028] The frame 1 includes two straight rods 11 and a curved rod 12. The two straight rods 11 and curved rod 12 are arranged opposite each other, and the rotating shaft 2 and drill bit 3 can be placed between the two straight rods 11 and curved rod 12. The curved rod 12 can be fixed to the rails. A vertical rod 111 is fixed to one end of the straight rod 11, and the lower end of the vertical rod 111 can be placed against the ground near the rails. It should be noted that the number of straight rods 11 and curved rods 12 can be increased to increase the strength of the frame 1, as long as the rotating shaft 2 can be placed in the middle of the frame 1.

[0029] Reference Figure 2 Specifically, the bent rod 12 includes a first horizontal portion 121, a second horizontal portion 122, an inclined portion 123 and a bent portion 124. The first horizontal portion 121 is connected to one end of the straight rod 11, and the second horizontal portion 122 is located above the first horizontal portion 121. The inclined portion 123 is fixed between the first horizontal portion 121 and the second horizontal portion 122. The lower end of the inclined portion 123 is connected to the first horizontal portion 121, and the upper end of the inclined portion 123 is connected to the second horizontal portion 122. The second horizontal portion 122 is fixedly connected to the curved portion 124. The curved portion 124 can hook the rail head of the steel rail on one side of the track to limit the frame 1.

[0030] A support plate 112 is fixed to the lower end of the column 111. The support plate 112 can abut against the ground over a large area. The support plate 112 cooperates with the curved portion 124 to stably mount the frame 1 on the rail for subsequent drilling.

[0031] Furthermore, the bent rod 12 also includes a support portion 125, which is fixed to the inclined portion 123. The support portion 125 can abut the bottom of the rail on one side of the track, and cooperate with the curved portion 124 and the support plate 112 to further stably place the frame 1 on the rail. It should be noted that the proportional dimensions of the bent rod 12 are not necessarily as shown in the accompanying drawings. The height difference and lateral spacing between the support portion 125 and the curved portion 124 can be changed according to the distance and height difference between the rails on both sides of the track. Those skilled in the art can adjust the length and inclination angle of the inclined portion 123 according to the specific dimensions of the rail to adjust the height difference and lateral spacing between the support portion and the curved portion 124.

[0032] Two mounting plates 13 are fixed above the two straight rods 11. The mounting plates 13 are located between the two straight rods 11. A bearing 131 is fixed inside the mounting plates 13. The bearing 131 is coaxially arranged with the rotating shaft 2. The rotating shaft 2 passes through the bearing 131, so that the rotating shaft 2 can rotate and slide along the axial direction.

[0033] Reference Figure 3 A mounting bracket 14 is fixed to the upper side of the frame 1, and a frame 15 is fixed above the mounting bracket 14. A connecting shaft 151 is rotatably connected to the upper side of the frame 15. The axial direction of the connecting shaft 151 is the same as the axial direction of the rotating shaft 2. First sprockets 16 are fixed to both ends of the connecting shaft 151, so that the two first sprockets 16 can be rotatably connected to the upper side of the frame 1. Second sprockets 17 are provided below the two first sprockets 16. A chain 18 is provided between the first and second sprockets 16, 17. The rotation of one first sprocket 16 can drive the first sprockets 16 on both sides to rotate synchronously, and can also drive the rotation of the two second sprockets 17.

[0034] The rotating shaft 2 is passed through the second sprocket 17, and a limit strip 21 is fixed on the rotating shaft 2. A groove 181 is provided at the axial position of the second sprocket 17. The limit strip 21 is inserted into the groove 181 along the axial direction of the rotating shaft 2, so that the rotation of the second sprocket 17 can drive the rotating shaft 2 to rotate, and the rotating shaft 2 can also slide within a certain range in the second sprocket 17 along its own axial direction.

[0035] Furthermore, a crank 152 is fixed to the first sprocket 16 extending from one end of the connecting shaft 151. Turning the crank 152 can rotate the first sprocket 16. When drilling rails, the worker moves the drilling machine to the construction position, sets the frame 1 on the rail, places the upright 111 against the ground, and then engages the bent rod 12 with the rail to stabilize the position of the drilling machine. At this time, the drill bit 3 is placed against the rail drilling position and the crank 152 is turned to rotate the first sprocket 16. The first sprocket 16 drives the second sprocket 17 to rotate, thereby driving the rotating shaft 2 to rotate. The rotating shaft 2 drives the drill bit 3 to rotate and drill holes in the rail.

[0036] As an embodiment, a vertical plate 19 is fixed on the two straight rods 11, and a threaded hole is provided on the surface of the vertical plate 19. A feed shaft 191 is provided in the threaded hole. A threaded section is provided in the middle position of the feed shaft 191, and the threaded section is threadedly connected to the threaded hole. One end of the feed shaft 191 is rotatably connected to the rotating shaft 2, and a feed wheel 192 is fixed to the end of the feed shaft 191 away from the rotating shaft 2. By rotating the feed wheel 192, the feed shaft 191 can be driven to rotate, and the axial movement of the feed shaft 191 can be achieved through the threaded connection between the threaded hole and the threaded section. The rotational connection between the feed shaft 191 and the rotating shaft 2 makes it possible for the rotation of the feed shaft 191 to not affect the rotation of the rotating shaft 2 but to push the rotating shaft 2 to move axially, thereby realizing the feeding of the drill bit 3 and completing the rail drilling work.

[0037] As an embodiment, the diameter of the first sprocket 16 is larger than the diameter of the second sprocket 17, which can increase the rotation speed of the second sprocket 17, improve drilling efficiency, and reduce the labor intensity of workers.

[0038] The implementation principle of the present utility model is as follows: when performing rail drilling construction, the staff moves the drilling machine to the construction position, sets the frame 1 on the rail, abuts the vertical rod 111 on the ground, and then cooperates with the bent rod 12 to the rail to stabilize the position of the drilling machine. At this time, the drill bit 3 is pressed against the rail drilling position, and the crank 152 is turned to drive the first sprocket 16 to rotate, and the first sprocket 16 drives the second sprocket 17 to rotate, thereby driving the rotating shaft 2 to rotate. When the rotating shaft 2 completes drilling at a position and needs to be fed, the feed wheel 192 can be rotated to drive the rotating shaft 2 to feed, thereby realizing the feeding of the drill bit 3 and completing the rail drilling work.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
