[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figure 1 and Figure 2, the present utility model provides a technical solution: an adjustable tamping machine pick head loading and unloading rack, which includes a mounting base 1, a driving motor 2 and an adjusting screw 201. A control box 101 is installed inside the mounting base 1. A driving motor 2 is installed on one side of the mounting base 1. The output end of the driving motor 2 is connected to one end of the adjusting screw 201 through a coupling. The other end of the adjusting screw 201 is rotationally connected to the mounting base 1 through a bearing seat. The outside of the adjusting screw 201 is threadedly connected to a threaded hole inside a moving seat 3. A clamping assembly 4 is arranged on the upper side of the moving seat 3, and a stepping motor 401 is installed outside the clamping assembly 4;

[0023] One side of the clamping assembly 4 away from the stepping motor 401 is connected to a guiding layer 5. The outside of the guiding layer 5 is inserted into a guiding frame 501. Mounting frames 502 are installed at the bottom of the guiding frame 501 and on the upper side of the mounting base 1. A scissor cross arm 503 is arranged inside the mounting frame 502. One end of the scissor cross arm 503 is hinged to the mounting frame 502 through a pin shaft. The other end of the scissor cross arm 503 is slidably connected to the mounting frame 502 through a sliding rod. The outside of the scissor cross arm 503 is hinged to both ends of a hydraulic rod 504 through a mounting pin. Support rollers 301 are symmetrically installed at the bottom of the moving seat 3. A plugging slot 302 is opened inside the moving seat 3, and a plugging post 303 is opened inside the plugging slot 302. The top of the plugging post 303 is connected to the clamping assembly 4.

[0024] During specific implementation, to improve the usage range of the loading and unloading rack, after placing the pick head at the clamping assembly 4 and starting the stepping motor 401 for clamping, start the hydraulic rod 504 on one side of the scissor cross arm 503. When the hydraulic rod 504 extends, it pushes the scissor cross arm 503 to expand, pushing the guiding frame 501 to move upward. At this time, the guiding frame 501 drives the clamping assembly 4 connected to the guiding layer 5 to move upward through the guiding layer 5 inserted inside. At this time, the plugging post 303 at the bottom of the clamping assembly 4 will move upward along the plugging slot 302 inside the moving seat 3, raising the position of the clamping assembly 4 and the pick head;

[0025] Among them, the settings of the plugging slot 302 inside the moving seat 3 and the plugging post 303 at the bottom of the clamping assembly 4 facilitate the movement of the moving seat 3 driving the clamping assembly 4 while also facilitating the adjustment of the height of the clamping assembly 4. The same principle applies to the sliding settings of the guiding frame 501 and the guiding layer 5. The mounting frame 502 is used for the installation of the scissor cross arm 503. The setting of the support rollers 301 facilitates the movement of the moving seat 3 and can effectively improve the support effect of the moving seat 3. This adjustable tamping machine pick head loading and unloading rack can lift the position of the clamping assembly 4 while keeping the clamping assembly 4 moving, improving the vertical working range of the loading and unloading rack and reducing the loading and unloading error.

[0026] Refer to Figure 2 、 Figure 3 andFigure 4 It can be seen that a bidirectional servo motor 6 is installed inside the mounting base 1. A reserved groove 607 is formed at the bottom of the mounting base 1. Both ends of the bidirectional servo motor 6 are connected to threaded rods 601 through couplings. The two threaded rods 601 are rotatably connected to the mounting base 1 through bearing seats on the sides away from each other, and the outer threads of the threaded rods 601 are arranged with opposite thread directions. The outer side of the threaded rod 601 is threadedly connected to a moving plate 602 through a threaded groove. The inside of the moving plate 602 is penetrated and inserted by a support rod 603 through a slot hole. Both ends of the support rod 603 are welded to the mounting base 1. A moving arm 604, a moving roller 605 and a connecting arm 606 are arranged at the bottom of the moving plate 602. Both ends of the moving arm 604 are hinged to the moving plate 602 and the moving roller 605 respectively through a connecting shaft. Both ends of the connecting arm 606 are hinged to the moving roller 605 and the mounting base 1 respectively through a rotating shaft. The outer side of the moving roller 605 is penetrated and inserted into the reserved groove 607.

[0027] During specific implementation, to facilitate the movement of the loading and unloading rack, the bidirectional servo motor 6 is started through the control box 101. The bidirectional servo motor 6 drives the threaded rod 601 to rotate through the couplings on both sides. When the threaded rod 601 rotates, it acts with the threaded groove on the inner side of the moving plate 602, driving the moving plate 602 to move along the support rod 603 through the slot hole inside. While the moving plate 602 moves, it drives the moving arm 604 to move. When the moving arm 604 moves, it will push the moving roller 605 to open downward under the limiting action of the connecting arm 606, and then the loading and unloading rack can be pushed to move. Among them, while the support rod 603 provides a supporting effect for the moving plate 602, it also has a guiding function. The reserved groove 607 is used for the storage of the moving roller 605. This adjustable tamping car pick head loading and unloading rack can retract and extend the moving roller 605, facilitating the movement and stable placement of the loading and unloading rack, and the operation is flexible and simple.

[0028] In summary, when using this adjustable tamping car pick head loading and unloading rack, the drive motor 2 is started through the control box 101 to drive the adjusting screw 201 to rotate and act with the moving seat 3, driving the moving seat 3 and the clamping assembly 4 to move relatively to clamp the pick head. The stepping motor 401 is started to drive the pick head to rotate. The hydraulic rod 504 on one side of the scissor cross arm 503 is started to push the scissor cross arm 503 to unfold, raising the position of the clamping assembly 4 and the pick head, and then normal loading and unloading work can be carried out. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0029] Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
