Description

Technical Field

[0001] This utility model relates to chassis technology, specifically to a track-guided trolley chassis. Background Technology

[0002] A track-guided trolley is an automated transport device that travels on a specific track. It uses onboard sensors and a sophisticated guidance system to accurately identify and position the track, enabling it to efficiently and accurately transport goods between different stations. It is an indispensable and important component of modern logistics systems and automated production lines.

[0003] Existing track-guided trolley chassis typically use a combination of vertical and horizontal wheels to travel on the track surface. However, if there are foreign objects on the track, the vertical wheels will be lifted upwards due to the force when they encounter the foreign objects during travel, causing the chassis to lose balance. This can easily lead to the trolley deviating from the track, resulting in the cargo falling off the vehicle. Utility Model Content

[0004] The purpose of this invention is to provide a track-guided trolley chassis to address the shortcomings of existing trolley chassis that lose balance and deviate from the track when passing over foreign objects.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a track-guided trolley chassis, comprising a track body and a traveling unit;

[0006] The track body is symmetrically provided with side rails on its sides, and a central rail is provided in the middle of the track body. The side rails are provided with limit grooves on the side away from the central rail.

[0007] The walking unit includes a support plate, a support shaft, support wheels, a fixing sleeve, a rotating shaft, a limiting wheel, and a mounting groove.

[0008] A support plate is provided on the top of the track body, and a rectangular groove is provided through the middle of the top of the support plate;

[0009] Several mounting slots are respectively opened at the four corners of the top perimeter of the support plate;

[0010] Several rotating shafts are respectively disposed inside the mounting groove, and the rotating shafts pass through the support plate and extend to the bottom of the support plate;

[0011] Several fixed sleeves are respectively fitted onto the outside of the rotating shaft, and the top of the fixed sleeves is fixedly connected to the bottom of the support plate;

[0012] Several limiting wheels are respectively sleeved on the bottom end of the rotating shaft. The limiting wheels are located below the fixed sleeve, and the outer side of the limiting wheels is connected to the side wall of the limiting groove.

[0013] The support shaft is fixedly installed inside the rectangular groove in the support plate;

[0014] A support wheel is rotatably mounted on the outside of the support shaft, and the outside of the support wheel is connected to the top of the central track.

[0015] Furthermore, the limiting wheel is rotatably connected to the rotating shaft.

[0016] Furthermore, the cross-section of the limiting wheel is octagonal.

[0017] Furthermore, the outer side of the rotating shaft is fixedly connected to the support plate through the penetration point.

[0018] Furthermore, it also includes elastic elements and limiting plates:

[0019] An elastic element is disposed inside the mounting groove, and the bottom end of the elastic element is fixedly connected to the bottom of the mounting groove opened in the support plate;

[0020] A limiting plate is disposed inside the mounting groove. The limiting plate is fixedly connected to the top of the rotating shaft and slidably connected to the inner wall of the mounting groove. The bottom of the limiting plate abuts against the top of the elastic element.

[0021] Furthermore, the outer side of the rotating shaft is slidably connected to the support plate at the point where they are penetrated.

[0022] Compared with the prior art, the present invention provides a track-guided trolley chassis in which the rotation of the limiting wheel drives the support plate to move on the surface of the track body through the rotating shaft. The support wheel shares the pressure of the entire traveling unit on the limiting wheel, reduces the friction between the limiting wheel and the side track, and reduces wear. When a foreign object appears on the top of the track body, the limiting wheel is used to provide longitudinal limit on the support plate when the support wheel passes over the foreign object, preventing the traveling unit from separating from the track body due to the tilt of the support plate, thus ensuring the stability of the traveling unit's operation.

[0030] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0031] Example 1:

[0032] Please see Figure 1 and Figure 2 A track-guided trolley chassis, comprising a track body 1 and a traveling unit 2;

[0033] The track body 1 is symmetrically provided with side rails 11 on its sides, and a central rail 13 is provided in the middle of the track body 1. A limit groove 12 is provided on the side of the side rails 11 away from the central rail 13.

[0034] The walking unit 2 includes a support plate 21, a support shaft 22, a support wheel 23, a fixing sleeve 24, a rotating shaft 25, a limiting wheel 26, and a mounting groove 27.

[0035] A support plate 21 is disposed on the top of the track body 1, and a rectangular groove is provided through the middle of the top of the support plate 21.

[0036] Several mounting slots 27 are respectively opened at the four corners of the top perimeter of the support plate 21;

[0037] Several rotating shafts 25 are respectively disposed inside the mounting groove 27, and the rotating shafts 25 pass through the support plate 21 and extend to the bottom of the support plate 21;

[0038] Several fixed sleeves 24 are respectively sleeved on the outside of the rotating shaft 25, and the top of the fixed sleeve 24 is fixedly connected to the bottom of the support plate 21;

[0039] Several limiting wheels 26 are respectively sleeved on the bottom end of the rotating shaft 25. The limiting wheels 26 are located below the fixed sleeve 24, and the outer side of the limiting wheels 26 is connected to the side wall of the limiting groove 12.

[0040] The support shaft 22 is fixedly installed inside the rectangular groove of the support plate 21;

[0041] The support wheel 23 is rotatably mounted on the outside of the support shaft 22, and the outside of the support wheel 23 is connected to the top of the central track 13.

[0042] The specific implementation is as follows: The walking unit 2 can move on the surface of the track body 1. The track body 1 can limit the movement route and trajectory of the walking unit 2. The track body 1 is cast in one piece of metal to ensure sufficient strength and stability. The track body 1 is provided with multiple tracks to limit the movement of the walking unit 2 and ensure the stability of the movement of the walking unit 2. Side tracks 11 are provided on both sides of the track body 1 along its length. The two side tracks 11 have V-shaped grooves with openings on their sides facing away from the central track 13. The central track 13 is located in the middle of the track body 1 and is arranged parallel to the side tracks 11. The limiting grooves 12 provided in the side tracks 11 are used to limit the vertical movement of the limiting wheel 26, and at the same time guide the movement direction and path of the limiting wheel 26 to prevent the walking unit 2 from separating from the track body 1 during movement. The shape and size of the limiting groove 12 match the outer dimensions of the limiting wheel 26 to ensure that the limiting wheel 26 can roll stably in it, thereby limiting the longitudinal and lateral movement of the track-guided trolley chassis on the track.

[0043] The central track 13 serves as a support track for the walking unit 2, providing support for the walking unit 2 and reducing the burden on the limiting wheel 26 when the walking unit 2 moves, thus accelerating the wear of the contact surface between the limiting wheel 26 and the side track 11. The top of the central track 13 contacts the support wheel 23, which rolls on it to assist the movement of the walking unit 2.

[0044] The support plate 21 is located above the track body 1. The support plate 21 does not directly contact the track body 1. The rectangular groove in the middle of the top of the support plate 21 is used to install the support shaft 22 and the support wheel 23. The support wheel 23 is rotatably connected to the support shaft 22. The support wheel 23 serves as an auxiliary support to distribute the overall weight of the walking unit 2 and reduce the wear between the limit wheel 26 and the side track 11 during operation.

[0045] Mounting slots 27 are provided at the four corners of the top of the support plate 21, and mounting slots 27 are used to mount the rotating shaft 25;

[0046] The pivot 25 extends through the support plate 21 to its bottom, and the pivot 25 is fixedly connected to the support plate 21 at the point through which it is passed.

[0047] The fixing sleeves 24 are respectively fitted on the outside of the rotating shaft 25, and their tops are fixedly connected to the bottom of the support plate 21. The function of the fixing sleeves 24 is to fix the rotating shaft 25 and prevent it from loosening or falling off during use.

[0048] The limiting wheels 26 are respectively fitted onto the bottom end of the rotating shaft 25, located below the fixed sleeve 24. The cross-section of the limiting wheels 26 is octagonal, which is intended to increase the contact area with the side wall of the limiting groove 12, improve the stability of the walking unit 2 running on the track body 1, and prevent the support plate 21 from tilting and overturning when obstacles appear on the top of the track body 1 and the support wheel 23 rolls over the obstacle.

[0049] The limit wheel 26 is rotatably connected to the rotating shaft 25.

[0050] The cross-section of the limiting wheel 26 is octagonal.

[0051] The specific implementation method is as follows: the limiting wheel 26 is used for both limiting and driving. The limiting wheel 26 rotates inside the limiting groove 12, and then drives the support plate 21 to move along the track of the track body 1 through the rotating shaft 25.

[0052] The outer side of the rotating shaft 25 is fixedly connected to the support plate 21 through the penetration point.

[0053] The rotation of the limiting wheel 26 drives the support plate 21 to move on the surface of the track body 1 via the rotating shaft 25. The support wheel 23 shares the pressure of the entire walking unit 2 on the limiting wheel 26, reduces the friction between the limiting wheel 26 and the side track 11, and reduces wear. When a foreign object appears on the top of the track body 1, the limiting wheel 26 is used to provide longitudinal limit on the support plate 21 when the support wheel 23 passes over the foreign object, preventing the support plate 21 from tilting, which would cause the walking unit 2 to separate from the track body 1 and cause the goods to overturn.

[0054] Example 2:

[0055] Please see Figure 3 and Figure 4 This embodiment provides a technical solution based on Embodiment 1: it further includes an elastic element 29 and a limiting plate 28.

[0056] The elastic element 29 is disposed inside the mounting groove 27, and the bottom end of the elastic element 29 is fixedly connected to the bottom of the mounting groove 27 opened in the support plate 21.

[0057] The limiting plate 28 is disposed inside the mounting groove 27. The limiting plate 28 is fixedly connected to the top of the rotating shaft 25, and the limiting plate 28 is slidably connected to the inner wall of the mounting groove 27. The bottom of the limiting plate 28 abuts against the top of the elastic element 29.

[0058] The outer side of the rotating shaft 25 is slidably connected to the support plate 21 through the penetration point.

[0059] The specific implementation method is as follows: the elastic element 29 includes, but is not limited to, a spring. The elastic force of the elastic element 29 is greater than the gravity generated by the weight of the limiting wheel 26. The rotating shaft 25 can move along its own axis. When the support wheel 23 crushes the foreign object, the support wheel 23 drives the support plate 21 to move upward as a whole through the support shaft 22. At this time, the limiting wheel 26 drives the rotating shaft 25 to remain stationary. The elastic element 29 is compressed, and the support plate 21 can move upward. After the support wheel 23 passes the obstacle, the support plate 21 automatically resets.

[0060] Example 3:

[0061] Based on Embodiment 2, a pressure sensor can also be installed at the bottom of the elastic element 29, and an alarm device electrically connected to the pressure sensor is installed on the side of the support plate 21. When the walking unit 2 moves on the top of the track body 1 and crushes foreign objects, the elastic element 29 deforms, causing the pressure received by the pressure sensor to change rapidly, thereby triggering an alarm through the alarm device, which facilitates the staff to locate and clean up obstacles on the surface of the track body 1 in a timely manner.

[0062] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
