Specific embodiments

[0032] The present invention will be further described below with reference to the accompanying drawings.

[0033] As Figure 1 and Figure 2 shown, the thread tapping machine for maintenance of the present invention may include a base 1, a movable seat 2 and a thread tapping assembly. The movable seat 2 is connected to the base 1 through an adjustment mechanism, and the thread tapping assembly is installed on the movable seat 2 through a lifting column 3;

[0034] The thread tapping assembly is used for threading the drilled hole. The lifting column 3 can adjust the position of the thread tapping assembly, and the adjustment mechanism can drive the thread tapping assembly to feed in the depth direction of the drilled hole.

[0035] Specifically, the base 1 is the overall bearing foundation of the thread tapping machine for maintenance, and the upper surface of the base 1 is horizontal. The movable seat 2 is the support foundation of the thread tapping assembly. A lifting column 3 is installed on the top of the movable seat 2. The lifting column 3 is perpendicular to the base 1. The thread tapping assembly is installed at the telescopic end of the lifting column 3. The thread tapping assembly can be adjusted in height as the lifting column 3 expands and contracts, so as to correspond to the drilled hole. An adjustment mechanism is installed on the base 1, and the movable seat 2 is connected to the adjustment mechanism. The adjustment mechanism can drive the movable seat 2 to move horizontally relative to the base 1, and then drive the thread tapping assembly to feed in the depth direction of the drilled hole. Coupled with the rotation of the thread tapping assembly itself, the threading operation of the drilled hole can be realized.

[0036] In this way, the thread tapping machine for maintenance is convenient for adjusting the position corresponding to threading, and can make the thread tapping assembly move smoothly in the depth direction of the drilled hole. It does not require the operator to manually cooperate for threading, reduces the probability of threading errors, and improves the operation accuracy.

[0037] Further, the thread tapping assembly includes a thread tapping tool 4 and a thread tapping motor 5. The thread tapping tool 4 is connected to one side of the lifting column 3 through a column, and the thread tapping motor 5 is connected to the other side of the lifting column 3 through a mounting box. The thread tapping motor 5 provides rotational power for the thread tapping tool 4 and can drive the thread tapping tool 4 to rotate around its own central axis.

[0038] It should be noted that the central axis of the thread tapping tool 4 is parallel to the central axis of the output end of the thread tapping motor 5. When the thread tapping assembly corresponds to the drilled hole, the central axis of the thread tapping tool 4 is collinear with the central axis of the drilled hole.

[0039] In one example, asFigures 1 to 3 As shown, the adjusting mechanism includes a horizontally arranged guide rod 6. The guide rod 6 is fixed to the base 1. The movable seat 2 is sleeved on the guide rod 6, and the movable seat 2 can move along the guide rod 6.

[0040] Specifically, the left and right ends of the base 1 have upward protrusions, and the overall structure is concave. The two ends of the guide rod 6 are respectively fixedly connected to the protrusions at the two ends of the base 1. The guide rod 6 is horizontal and parallel to the upper surface of the base 1. The movable seat 2 is provided with a through hole matching the guide rod 6, and can be sleeved on the guide rod 6 through the through hole, so that the movable seat 2 can only slide along the length direction of the guide rod 6. It should be noted that the length direction of the guide rod 6 is parallel to the central axis of the tapping tool 4.

[0041] Furthermore, as Figure 3 shown, the adjusting mechanism includes two guide rods 6. The two guide rods 6 are parallel and are respectively located on the front and rear sides of the movable seat 2. The movable seat 2 is correspondingly provided with two through holes. This enables the movable seat 2 to be circumferentially fixed relative to the guide rod 6, avoiding circumferential shaking of the movable seat 2 around the guide rod 6, and can reduce the probability of errors occurring during tapping. It should be noted that the two guide rods 6 can be symmetrically distributed with respect to the lateral midline of the movable seat 2, that is, the two guide rods 6 are symmetric with each other in the front and rear.

[0042] It should be noted that the description of the front, rear, left, and right directions for maintaining the tapping machine is based on the angle in the appendix Figure 1 as a reference.

[0043] In one example, as Figure 2 shown, the adjusting mechanism further includes a driving feed component arranged in the storage cavity of the base 1. The driving feed component is connected to the bottom of the movable seat 2, and the driving feed component can drive the movable seat 2 to move along the guide rod 6.

[0044] Specifically, the base 1 is provided with a storage cavity located below the movable seat 2, and the storage cavity is convenient for installing the driving feed component. The driving feed component is installed in the storage cavity and is connected to the bottom of the movable seat 2. The driving feed component can drive the movable seat 2 to slide along the guide rod 6.

[0045] Furthermore, as Figure 2 shown, the driving feed component includes a driving motor 7, a screw rod 8, and a threaded sleeve 9. The driving motor 7 is installed in the storage cavity of the base 1. The output end of the driving motor 7 is connected to one end of the screw rod 8. The other end of the screw rod 8 is rotatably connected to the base 1. The threaded sleeve 9 is sleeved on the screw rod 8 and is fixedly connected to the movable seat 2.

[0046] Specifically, the drive motor 7 is fixedly installed in the storage cavity of the base 1. The output end of the drive motor 7 is connected to one end of the screw rod 8, and the other end of the screw rod 8 is rotatably connected to the base 1. The drive motor 7 can drive the screw rod 8 to rotate around its own central axis. The threaded sleeve 9 is fixedly connected to the bottom of the movable seat 2 and is sleeved on the screw rod 8 at the same time. The internal thread of the threaded sleeve 9 matches the external thread of the screw rod 8. When the drive motor 7 drives the screw rod 8 to rotate, the screw rod 8 can be in spiral cooperation with the threaded sleeve 9, so that the threaded sleeve 9 moves along the length direction of the screw rod 8, and further the movable seat 2 and the tapping assembly move along the length direction of the screw rod 8.

[0047] Furthermore, the screw rod 8 is parallel to the guide rod 6. One end of the screw rod 8 close to the drive motor 7 is sleeved with a partition plate 10, and the other end of the screw rod 8 far from the drive motor 7 is connected to the base 1 through a bearing seat.

[0048] Specifically, the screw rod 8 is parallel to the guide rod 6, that is, the length direction of the screw rod 8 is parallel to the central axis of the tapping tool 4. One end of the screw rod 8 close to the drive motor 7 is sleeved with a partition plate 10, and the screw rod 8 can rotate within the partition plate 10. The partition plate 10 is fixedly arranged in the storage cavity of the base 1. The other end of the screw rod 8 far from the drive motor 7 is connected to the base 1 through a bearing seat, and the bearing seat is installed on the inner wall of the storage cavity of the base 1. The partition plate 10 and the bearing seat can play an auxiliary supporting role for the screw rod 8, so that the screw rod 8 only rotates around its own central axis, and further makes the movable seat 2 drive the tapping assembly to tap the drilled hole more smoothly.

[0049] In one example, as Figure 1 shown, the maintenance tapping machine further includes moving wheels 20 and a fixing mechanism arranged on the base 1. The moving wheels 20 can move the base 1, and the fixing mechanism can fix the base 1.

[0050] Specifically, a plurality of moving wheels 20 are installed at the bottom of the base 1. The moving wheels 20 facilitate the movement of the maintenance tapping machine, so that it is not necessary to move the rail drilling machine to the maintenance location, but to move the maintenance tapping machine near the rail drilling machine for tapping, thereby reducing the maintenance time and improving the work efficiency. At the same time, the moving wheels 20 can facilitate the adjustment of the position of the base 1, and further enable the position of the tapping assembly to correspond to the drilled hole. A fixing mechanism is arranged on the side of the base 1. When the base 1 is moved and adjusted to the specified position by the moving wheels 20, the fixing mechanism can fix the position of the base 1 to prevent the base 1 from moving during the tapping operation, resulting in tapping errors, and improving the operation accuracy. The moving wheels 20 can be universal wheels.

[0051] In one example, as Figure 1 、 Figure 4 and Figure 5As shown in the figure, the fixing mechanism includes a plurality of first fixing components symmetrically distributed on both sides of the base 1. The first fixing component includes a fixing plate 13, a movable rod 12 and a hydraulic rod 11 that are both hinged to the base 1. The fixing plate 13 is connected to the movable rod 12, and the hydraulic rod 11 and the end of the movable rod 12 away from the base 1 are hinged to each other. The hydraulic rod 11 can drive the movable rod 12 to drive the fixing plate 13 to rotate downward.

[0052] Specifically, a plurality of first fixing components that are symmetrically distributed front and back are provided on both the front and back sides of the base 1, and the plurality of first fixing components on each side are in a left-right symmetrical relationship. The hydraulic rod 11 and the movable rod 12 are both movably connected to the side of the base 1 through a connecting seat. At the same time, the end (output end) of the hydraulic rod 11 away from the base 1 is rotatably connected to the end of the movable rod 12 away from the base 1, and the fixing plate 13 is connected to the end of the movable rod 12 away from the base 1. The connection position of the hydraulic rod 11 to the base 1 is higher than the connection position of the movable rod 12 to the base 1, that is, the hydraulic rod 11 is located above the movable rod 12. When the hydraulic rod 11 expands and contracts, it can drive the movable rod 12 to drive the fixing plate 13 to rotate downward, so that the fixing plate 13 is docked with the ground to fix the base 1.

[0053] Further, as shown in Figure 4 and Figure 5 the figure, the fixing plate 13 is hinged to the movable rod 12 through a connecting rod, and a reset elastic member 14 is provided between the rod body of the movable rod 12 and the fixing plate 13.

[0054] Specifically, the fixing plate 13 is rotatably connected to the movable rod 12 through a connecting rod. When the hydraulic rod 11 extends and drives the movable rod 12 to rotate downward, the hydraulic rod 11 and the movable rod 12 both rotate downward through a transfer seat. Until the fixing plate 13 is close to the ground, the fixing plate 13 is docked with the ground by rotating the connecting rod, and is tightened against the ground under the driving action of the hydraulic rod 11 to realize the fixation of the base 1. During the process of the fixing plate 13 rotating relative to the movable rod 12, the reset elastic member 14 will be squeezed, causing the reset elastic member 14 to deform. When it is necessary to release the first fixing component, through the deformation force of the reset elastic member 14, it can play a role in assisting to cancel the docking of the fixing plate 13 with the ground. The reset elastic member 14 can be a reset spring.

[0055] In an example, as shown in Figure 1 、 Figure 6 and Figure 7 the figure, the fixing mechanism further includes a second fixing component located at one end of the base 1. The second fixing component includes an extension seat 15, a bolt 16 and a fixing block 17. The extension seat 15 is fixed to the base 1. One end of the bolt 16 is hinged to the fixing block 17, and the bolt 16 spirally penetrates through the extension seat 15 and can adjust the position of the fixing block 17.

[0056] Specifically, the fixing mechanism includes a plurality of second fixing components located at the left end of the base 1, and the plurality of second fixing components are symmetrically arranged front and back. The left end of the base 1 is fixedly connected with an extension base 15. The extension base 15 has a threaded hole penetrating up and down. A bolt 16 penetrates through the threaded hole and its bottom end is connected with a fixing block 17 through a rotating seat. The bolt 16 can adjust the height position of the fixing block 17 by screw rotation, so that the fixing block 17 can be fixed to the ground. At the same time, the rotating seat enables the fixing block 17 to adapt to the ground with different slopes.

[0057] In one example, as Figure 4 shown, a plurality of storage cavities are provided at one end of the base 1, and a pull-out storage box 18 is fitted and installed in each storage cavity.

[0058] Specifically, a plurality of storage cavities are provided at the right end (the end far from the extension base 15) of the base 1, and a pull-out storage box 18 is fitted and installed in each storage cavity. The plurality of storage cavities are arranged in parallel from top to bottom in sequence, so that the plurality of storage boxes 18 are also parallel to each other. A handle 19 is provided on each storage box 18 for easy pulling to open or close. The storage box 18 can be used for classifying and storing towels and rust removers. When there is rust on the workpiece to be tapped, the towels and rust removers can be taken out and used in combination to clean the rust, so that there is no need to specifically look for other rust removal equipment to remove the rust from the workpiece.

[0059] To better understand the above embodiments, the following further describes the use process of the maintenance tapping machine of the present utility model applied to a rail drilling machine with reference to the accompanying drawings.

[0060] When a failure occurs during the process of the rail drilling machine drilling a hole in the railway, after the outer shell of the rail drilling machine is removed for maintenance and it is necessary to drill a hole again in the rail drilling machine to install the outer shell:

[0061] (1) The maintenance tapping machine can be moved to the vicinity of the rail drilling machine through the moving wheels 20; then start the hydraulic rod 11 to drive the movable rod 12 to rotate. At this time, the hydraulic rod 11 rotates downward through the connecting seat, and the movable rod 12 rotates downward through the adapter seat. Until the fixed disk 13 is close to the ground, the fixed disk 13 is docked with the ground by rotating the connecting rod to fix the base 1; then rotate the bolt 16. At this time, the bolt 16 is in threaded connection with the extension base 15 until the fixing block 17 is docked with the ground, and the fixing block 17 is adapted to the ground with different slopes through the rotating seat, thereby increasing the stress area and friction between the maintenance tapping machine and the ground, making the base 1 more firmly fixed. And during the rotation of the fixed disk 13, the reset elastic member 14 will be squeezed, causing the reset elastic member 14 to deform. Then, through the reset action of the reset elastic member 14, the docking of the fixed disk 13 with the ground can be assisted to be cancelled. In this way, the rail drilling machine can be tapped without moving it to the maintenance location, thus reducing the maintenance time and improving the work efficiency.

[0062] (2) Adjust the tapping tool 4 to the specified position where tapping is required for the rail drilling machine through the lifting column 3, so as to facilitate the adjustment of the corresponding tapping position. Then start the tapping motor 5 to drive the tapping tool 4 to rotate, and then start the driving motor 7 to drive the screw rod 8 to rotate. The rotation of the screw rod 8 drives the threaded sleeve 9 to move. The threaded sleeve 9 drives the movable seat 2 to move along the length direction of the screw rod 8. At the same time, the guide rod 6 plays a role in guiding and limiting the movement of the movable seat 2, and the partition plate 10 plays a role in assisting the support of the screw rod 8. In this way, the tapping of the drill hole on the rail drilling machine can be carried out smoothly, and there is no need for the operator to manually cooperate to tap the drill hole, which can reduce the probability of tapping errors.

[0063] (3) When a large amount of rust layer is found on the surface of the rail drilling machine, first open the storage box 18 containing the rust remover through the handle 19, and then take out the rust remover and spray it on the rust layer; then open the storage box 18 containing the towel, take out the towel and clean the rust with the cooperation of the rust remover. In this way, there is no need to specifically search for other rust removal equipment to remove rust from the shell of the rail drilling machine, which can play a role in facilitating the cleaning of rust for maintaining the tapping machine.

[0064] In summary, the beneficial effects of the tapping machine maintenance of the present utility model include:

[0065] When the tapping machine maintenance of the present utility model is in use, through the mutual cooperation of structures such as the lifting column and the driving motor, it has the function of reducing the probability of tapping errors; through the mutual cooperation of structures such as the moving wheels, hydraulic rods and bolts, the fixed plate and the fixed block are docked with the ground, and the tapping machine maintenance can be moved and fixed near the rail drilling machine, thus having the function of reducing the maintenance time; through the design of the storage box, it has the function of facilitating the cleaning of rust.

[0066] Although the present utility model has been described with reference to the preferred embodiments, various improvements can be made to it and its components can be replaced with equivalents without departing from the scope of the present utility model. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
