Description

Technical Field

[0001] The utility model relates to the technical field of logistics, warehousing and transportation technology, and in particular to a track system for a loop ground rail shuttle vehicle. Background Art

[0002] With the continuous development of the logistics and transportation industry, the efficiency requirements for logistics and transportation are also constantly increasing. The circular shuttle system is widely used in automated warehousing systems due to its wide operating capacity range and high scheduling flexibility.

[0003] Chinese invention patent application number: "202510674285.5 A overtaking system for circular RGV", which realizes the track change and overtaking operation of the circular shuttle vehicle during application through the mutual coordination between the sliding and rotation of multiple tracks, thereby improving the transportation efficiency of the shuttle vehicle.

[0004] However, during use, it was found that during the track switching process, the rollers set between the sliding frame and the support frame are prone to wear under the action of long-term track change pressure, resulting in a smaller roller radius, and thus the sliding frame slides unstably and the track change is not smooth. Utility Model Content

[0005] The purpose of the utility model is to provide a track system for a loop ground rail shuttle vehicle to solve the above-mentioned deficiencies in the prior art.

[0006] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0007] The track system for the loop ground rail shuttle vehicle includes a support frame and a sliding frame. The sliding frame is provided with a compensation seat. The compensation seat is rotatably provided with a roller, and the roller abuts against the support frame.

[0008] A guide column is fixedly provided on the compensation seat, and the guide column is slidably connected to the sliding frame;

[0009] A threaded ring is rotatably provided on the sliding frame, a screw is fixedly provided on the compensation seat, and the screw is threadedly connected to the threaded ring;

[0010] It also includes a pressing component, which causes the compensation seat to slide when the sliding frame slides to compensate for the wear of the roller.

[0011] As a preferred technical solution of the present invention, a rotating rod is rotatably provided on the sliding frame, a worm is fixedly provided on the rotating rod, a worm wheel is fixedly provided on the threaded ring, and the worm and the worm wheel are meshed for transmission.

[0012] As a preferred technical solution of the present invention, the pressing assembly includes a pressing tube slidably arranged on a sliding frame, the pressing tube is provided with a spiral groove, the rotating rod is fixedly provided with a protrusion, and the protrusion is slidably arranged in the spiral groove.

[0013] As a preferred technical solution of the present invention, an abutment pin is slidably provided on the support frame, and the abutment pin is in abutment with the pressing tube.

[0014] As a preferred technical solution of the present invention, a spring is provided between the abutment pin and the support frame, and both ends of the spring are fixedly connected to the abutment pin and the support frame respectively.

[0015] In the above technical solution, the track system for the loop ground rail shuttle provided by the utility model has the following beneficial effects:

[0016] The sliding frame slides on the support frame through the sliding compensation seat. When the roller is worn and the radius becomes smaller, the threaded ring is rotated by pressing the component, pushing the screw and the compensation seat to slide, ensuring that after the roller radius becomes smaller, it can still abut against the support frame, thereby ensuring the sliding stability of the sliding frame and thus ensuring the track change stability.

[0017] It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the disclosure.

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0027] See also Figure 1-4 The track system for the circular ground rail shuttle vehicle includes a support frame 1 and a sliding frame 2. The sliding frame 2 is provided with a compensation seat 21, and a roller 22 is rotatably provided on the compensation seat 21, and the roller 22 abuts against the support frame 1; a guide column 24 is fixedly provided on the compensation seat 21, and the guide column 24 is slidably connected to the sliding frame 2; a threaded ring 25 is rotatably provided on the sliding frame 2, and a screw 23 is fixedly provided on the compensation seat 21, and the screw 23 is threadedly connected to the threaded ring 25; it also includes a pressing component, when the sliding frame 2 slides, the compensation seat 21 slides to compensate for the wear of the roller 22, and when the sliding frame 2 slides on the support frame 1, the roller 22 is used to guide the sliding of the sliding frame 2 And reduce friction. During this process, the roller 22 is subjected to pressure and rolls in contact with the support frame 1. After long-term use, the roller 22 will wear and the radius will become smaller, resulting in an inability to stably contact with the support frame 1, affecting the sliding stability of the sliding frame 2. After the roller 22 is worn, during the sliding process of the sliding frame 2, the threaded ring 25 is rotated by pressing the component. The rotation of the threaded ring 25 causes the screw 23 to slide with the compensation seat 21, so that the roller 22 contacts the support frame 1. In this way, after the roller 22 is worn and the radius is reduced, it can still play a good guiding and friction reducing role for the sliding of the sliding frame 2, thereby ensuring the smoothness of the sliding frame 2 when sliding and changing tracks.

[0028] Specifically, a rotating rod 3 is rotatably provided on the sliding frame 2, a worm 31 is fixedly provided on the rotating rod 3, and a worm wheel 26 is fixedly provided on the threaded ring 25. The worm 31 and the worm wheel 26 are meshed for transmission. When the roller 22 is worn and the radius becomes smaller, the rotating rod 3 drives the worm 31 to rotate by pressing the component during the sliding process of the sliding frame 2, and the rotation of the worm 31 causes the worm wheel 26 and the threaded ring 25 to rotate, thereby completing the sliding of the compensation seat 21 and the roller 22, ensuring that the roller 22 is in contact with the support frame 1, and after sliding, the self-locking effect of the worm wheel 26 and the worm 31 limits the compensation seat 21 and the roller 22, thereby ensuring the stability of the contact between the roller 22 and the support frame 1.

[0029] In an embodiment further provided by the present invention, the pressing assembly includes a pressing tube 4 slidably arranged on the sliding frame 2, a spiral groove 41 is provided on the pressing tube 4, a protrusion 32 is fixedly provided on the rotating rod 3, and the protrusion 32 is slidably arranged in the spiral groove 41. During the sliding process of the sliding frame 2, the pressing tube 4 slides, and through the cooperation between the spiral groove 41 and the protrusion 32, the rotating rod 3 is rotated, so that the roller 22 with a smaller radius can contact the support frame 1.

[0030] Furthermore, an abutment pin 11 is provided on the support frame 1 for sliding, and the abutment pin 11 abuts against the pressing tube 4. A spring 12 is provided between the abutment pin 11 and the support frame 1, and both ends of the spring 12 are fixedly connected to the abutment pin 11 and the support frame 1 respectively. During the sliding process of the sliding frame 2, the pressing tube 4 abuts against the abutment pin 11. At this time, if the roller 22 does not contact the support frame 1 due to the smaller radius, the pressing tube 4 slides under the abutment of the abutment pin 11, and the spiral groove 41, the protrusion 32, the rotating rod 3, and the worm are rotated. 31, the worm gear 26, the threaded ring 25, and the screw 23 drive the compensation seat 21 and the roller 22 to slide, so that the roller 22 contacts the support frame 1 to ensure the stable sliding of the sliding frame 2. When the roller 22 abuts against the support frame 1, the abutment pin 11 abuts against the pressing tube 4 during the sliding process of the sliding frame 2. At this time, under the self-locking action of the screw 23 and the threaded ring 25, the worm gear 26 and the worm 31, the rotating rod 3 cannot rotate. At this time, the sliding frame 2 continues to slide, causing the spring 12 to stretch to ensure that the sliding frame 2 continues to slide.

[0031] In the present application, the four corners of the sliding frame 2 are all configured identically, so that the four rollers 22 on the sliding frame 2 can all slide adaptively after their radius becomes smaller due to wear, thereby ensuring the stable contact between each roller 22 and the support frame 1 and improving the sliding stability of the sliding frame 2. At the same time, this process is achieved through the sliding of the sliding frame 2 without the need for manual operation. At the same time, the degree of wear of the corresponding roller 22 can be more intuitively judged by the distance the pressing tube 4 slides into the sliding frame 2.

[0032] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
