An anti-slip moving mechanism, a sorting trolley and a sorting system

Abstract

This invention provides an anti-slip moving mechanism, a sorting trolley, and a sorting system. The anti-slip moving mechanism includes a moving frame and a drive wheel assembly. The drive wheel assembly includes a mounting frame, a moving drive source, an active drive wheel, and a driven drive wheel. The moving drive source is connected to the active drive wheel, and the active and driven drive wheels are in contact with the transport track. Both the active and driven drive wheels are concave wheels with grooves on their outer circumferences. These grooves accommodate portions of the transport track, ensuring surface contact between the active and driven drive wheels and the transport track, as well as between the driven and driven drive wheels and the transport track. This application increases the contact surface between the active and driven drive wheels and the transport track, preventing slippage of the active and driven drive wheels relative to the transport track. The anti-slip moving mechanism enables rapid start and stop with a fast response. Using the anti-slip moving mechanism in automated logistics sorting improves sorting efficiency.

Description

Technical Field

[0001] This invention relates to the field of logistics sorting and conveying technology, and in particular to an anti-slip moving mechanism, a sorting trolley equipped with the anti-slip moving mechanism, and a sorting system equipped with the sorting trolley. Background Technology

[0002] With the rapid development of the e-commerce industry, the market demand for automated sorting machines (also known as sorting systems) that can automatically sort goods and improve logistics efficiency has increased significantly. They are widely used in production logistics systems or logistics distribution centers in various industries. Automated sorting machines typically include a fixed frame, a transport track fixedly installed on the fixed frame, a feeding mechanism for conveying goods into the fixed frame, a receiving mechanism arranged on the outside of the fixed frame, and sorting trolleys that move along the transport track. The sorting trolleys receive goods from the feeding mechanism, then move along the transport track to the corresponding delivery position in the receiving mechanism, and deliver the goods to the receiving mechanism, thus completing one sorting operation.

[0003] Previously, in the sorting cart developed by the applicant, such as Figure 1 As shown, four sets of driven wheel sets 102 are configured at the bottom of the sorting cart frame 101. The four sets of driven wheel sets 102 are respectively located at the four corners of the bottom of the frame 101. Meanwhile, a drive wheel set 103 is set in front of one of the driven wheel sets 102. The drive wheel set 103 mainly includes a drive motor 104, a drive wheel 105 driven by the drive motor 104, a limiting wheel 106 arranged side by side with the drive wheel 105, and a support 107. The drive motor 104, drive wheel 105 and limiting wheel 106 are all integrated and installed on the support 107. The support 107 is then fastened to the frame 101 with bolts, so that the drive wheel set 103 is fixed to the front end of the sorting cart frame 101. Meanwhile, to ensure the limiting wheel 106 better conforms to the transport track, a spring 108 and a cantilever 109 are also provided in the drive wheel assembly 103. The limiting wheel 106 is mounted on the cantilever 109, which is hinged to the support 107. The spring 108 is located between the support 107 and the cantilever 109. The spring 108 is a tension spring, which applies a force towards the drive wheel 105 to the cantilever 109, causing the limiting wheel 106 to conform to the transport track.

[0004] However, the sorting trolley has the following problems during operation: 1. Both the drive wheel and the limit wheel are cylindrical, and their contact with the transport track is only line contact or even point contact, resulting in a small contact area and easy slippage. This leads to a slow start-stop response speed of the sorting trolley, which is not conducive to further improving the sorting efficiency of the automatic sorting machine. 2. Even if springs and cantilever arms are set in the drive wheel group, the springs are inclined and have a component force; moreover, the lever arm between the spring and the limit wheel is long in the vertical direction, which weakens the clamping force applied to the limit wheel. This results in the limit wheel not being able to reliably hold onto the transport track, so the anti-slip effect of the springs and cantilever arms is very limited. Summary of the Invention

[0005] In view of the shortcomings of the prior art described above, the technical problem to be solved by the present invention is to provide an anti-slip moving mechanism that improves the anti-slip effect with the transport track and facilitates rapid start and stop.

[0018] The preferred embodiment of the above technical solution is as follows: the adaptive wheel set further includes a clamp provided at the upper and / or lower end of the bearing and fixed to the first support shaft, and an elastic component or gasket is provided between the clamp and the bearing.

[0019] The preferred embodiment of the above technical solution is that both the limiting wheel and the anti-detachment wheel are rubber-coated wheels, each including a wheel body and a rubber coating layer covering the outer periphery of the wheel body.

[0020] The preferred embodiment of the above technical solution is that the material of the coating layer is any one of polymer materials, nylon, rubber and silicone.

[0021] A preferred embodiment of the above technical solution is as follows: the walking drive wheel set further includes a first walking wheel rotatably mounted on the mounting frame, the first walking wheel being used to fit against the top of the transport track.

[0022] The preferred embodiment of the above technical solution is: the anti-slip movement mechanism further includes three sets of walking wheel sets, and the walking drive wheel sets and the three sets of walking wheel sets are arranged in a rectangular shape;

[0026] The preferred embodiment of the above technical solution is as follows: the bottom of the guide wheel is fixedly provided with a wheel protrusion ring, the wheel protrusion ring is located near the bottom of the transport track and can abut against the bottom of the transport track.

[0030] This application utilizes a mobile drive source to rotate the active drive wheel, and the active and driven drive wheels engage with each other on both sides of the transport track, driving the walking drive wheel assembly to move the entire anti-slip moving mechanism along the transport track. Specifically, both the active and driven drive wheels have concave wheel structures with grooves to accommodate portions of the transport track, thus achieving surface contact between the active and driven drive wheels and the transport track, as well as between the driven and driven drive wheels and the transport track. This increases the contact area between the active and driven drive wheels and the transport track, preventing slippage. Consequently, the anti-slip moving mechanism can start and stop quickly and respond rapidly due to its anti-slip structural characteristics. Applying this anti-slip moving mechanism to the field of automated logistics sorting will further improve sorting efficiency. Attached Figure Description

[0043] This invention provides an anti-slip moving mechanism for installation on a conveying device, driving the conveying device to move along a transport track 73. The transport track 73 can be an oblong closed track, or other irregularly shaped closed tracks, or a curved S-shaped track, or a curved L-shaped track, or other irregularly shaped curved tracks, or a straight track.

[0044] like Figures 2 to 4 As shown, the anti-slip moving mechanism of the present invention includes a movable frame 10 movably mounted on a transport track 73 and a driving wheel assembly 20. For ease of description, the moving direction of the movable frame 10 is defined as the forward direction, and the direction perpendicular to the moving direction of the movable frame 10 is the left-right direction. The driving wheel assembly 20 includes a mounting frame 21 rotatably mounted on the movable frame 10 about a vertical axis, a moving drive source 22 mounted on the mounting frame 21, and an active drive wheel 23 and a driven drive wheel 24, both rotatably mounted on the mounting frame 21 about a vertical axis. The moving drive source 22 is connected to the active drive wheel 23 and drives the active drive wheel 23 to rotate. The active drive wheel 23 and the driven drive wheel 24 are arranged side by side and attached to the left and right sides of the transport track 73. Specifically, both the active drive wheel 23 and the driven drive wheel 24 are concave wheels with fitting grooves 25 on their outer periphery. The fitting grooves 25 accommodate a portion of the transport track 73, so that the active drive wheel 23 and the transport track 73, as well as the driven drive wheel 24 and the transport track 73, are in surface contact.

[0045] In the aforementioned anti-slip moving mechanism, when the moving drive source 22 is activated, it drives the active drive wheel 23 to rotate, while the driven drive wheel 24 is a non-powered wheel. When the moving drive source 22 drives the active drive wheel 23 to rotate, the active drive wheel 23 and the driven drive wheel 24 engage on the left and right sides of the transport track 73, enabling the active drive wheel 23 and the driven drive wheel 24 to move along the transport track 73, thereby driving the entire anti-slip moving mechanism to move along the transport track 73. In this application, both the active drive wheel 23 and the driven drive wheel 24 are configured as concave wheel structures, each having a groove 25 that accommodates a portion of the transport track 73. This achieves surface contact between the active drive wheel 23 and the transport track 73, and between the driven drive wheel 24 and the transport track 73, increasing the contact surface between the active drive wheel 23 and the driven drive wheel 24 and the transport track, thereby increasing friction and preventing the active drive wheel 23 and the driven drive wheel 24 from slipping relative to the transport track. Thus, the anti-slip moving mechanism can start and stop quickly due to its anti-slip structural characteristics. This rapid start / stop advantage allows for shorter safety distances between adjacent anti-slip moving mechanisms, improving conveying efficiency. Furthermore, applying the anti-slip moving mechanism to automated sorting systems further enhances sorting efficiency.

[0046] Preferably, such as Figure 4 As shown, the mobile drive source 22 is a motor. The motor shaft of the mobile drive source 22 is rotatably supported in the mounting bracket 21 by bearings. The motor shaft of the mobile drive source 22 can be connected to the drive wheel 23 via a synchronous belt pulley assembly, or the drive wheel 23 can be directly fixed to the motor shaft of the mobile drive source 22. In this embodiment, the drive wheel 23 is directly fixed to the motor shaft of the mobile drive source 22, making the overall structure of the walking drive wheel set 20 more compact.

[0047] Preferably, the shape of the fitting groove 25 matches the outer shape of the transport track 73, ensuring reliable contact between the groove wall surface of the fitting groove 25 and the outer peripheral surface of the transport track 73. For example, in one embodiment, such as Figure 8As shown, the transport track 73 is a cylindrical track, and in this case, the fitting groove 25 is an arc-shaped groove, with the arc-shaped groove surface of the fitting groove 25 in surface contact with the outer peripheral surface of the cylindrical track. Alternatively, in another embodiment, the transport track 73 is a square track, and in this case, the fitting groove 25 is a square groove, with the arc-shaped groove surface of the fitting groove 25 in surface contact with the outer peripheral surface of the cylindrical track. Furthermore, the active drive wheel 23 and the driven drive wheel 24 of the concave wheel structure can mesh well on the left and right sides of the transport track 73, providing vertical holding forces between the active drive wheel 23 and the transport track 73, and between the driven drive wheel 24 and the transport track 73. This limits the vertical offset between the active drive wheel 23 and the transport track 73, and between the driven drive wheel 24 and the transport track 73, preventing the active drive wheel 23 and the driven drive wheel 24 from derailing and ensuring the smooth operation of the anti-slip movement mechanism.

[0048] Furthermore, such as Figures 5 to 7 As shown, the walking drive wheel assembly 20 also includes a first fixed post 26 fixed to the bottom of the mounting frame 21, a clamping wheel frame 27 rotatably mounted to the bottom of the mounting frame 21, a second fixed post 28 fixed to the clamping wheel frame 27, and a clamping member 29. The driven drive wheel 24 is rotatably mounted to the clamping wheel frame 27. The clamping member 29 connects between the first fixed post 26 and the second fixed post 28, and applies a force to the second fixed post 28 toward the transport track 73. Thus, under the action of the clamping member 29, the clamping wheel frame 27 and the driven drive wheel 24 mounted on the clamping wheel frame 27 can be pulled toward the transport track 73, so that the driven drive wheel 24 reliably presses against one side of the transport track 73, improving the anti-slip effect. Preferably, the clamping member 29 is a tension spring or a damper. Figure 5 and Figure 7 In the embodiment shown, the clamping member 29 is a tension spring, and the two ends of the tension spring are connected to the first fixing post 26 and the second fixing post 28, respectively.

[0049] In particular, such as Figure 6 and Figure 7 As shown, along the axial direction of the driven wheel 24, i.e. Figure 6In the vertical direction of the view, the driven drive wheel 24 has a center line S and a central plane containing the center line S, which is parallel to the bottom horizontal plane of the driven drive wheel 24. In this application, on the one hand, the clamping member 29 is provided on the lower side of the mounting bracket 21 facing the driven drive wheel 24, so that the clamping member 29 is close to the center line of the driven drive wheel 24 in its axial direction, shortening the lever arm between the clamping member 29 and the driven drive wheel 24 in the vertical direction, so that the force applied by the clamping member 29 can better pull the driven drive wheel 24; on the other hand, the clamping member 29 is parallel to the central plane of the driven drive wheel 24 in its axial direction, avoiding the force applied by the clamping member 29 from generating a component force in other directions. Ultimately, this application enables the force applied by the clamping member 29 to be effectively transmitted to the driven drive wheel 24, so that the driven drive wheel 24 reliably fits the transport track 73 under the action of the clamping member 29, and more reliably ensures the anti-slip effect.

[0050] Furthermore, such as Figures 2 to 5 As shown, the walking drive wheel assembly 20 includes an adaptive wheel assembly mounted on the mounting frame 21. This adaptive wheel assembly enables the active drive wheel 23 and the driven drive wheel 24 to adapt to the elevation changes and lateral shifts of the transport track 73, ensuring that the active drive wheel 23 and the driven drive wheel 24 reliably engage with the transport track 73 at all times, thus improving the stability of the anti-slip movement mechanism. In this embodiment, the adaptive wheel assembly includes a limiting wheel 36 and a pair of anti-detachment wheels 32. The preferred structure of the limiting wheel 36 and the pair of anti-detachment wheels 32 is described below.

[0051] Furthermore, such as Figures 2 to 5 As shown, the adaptive wheel assembly of the walking drive wheel assembly 20 also includes a first wheel frame 31 and a first support shaft 34 fixed to the first wheel frame 31. The first wheel frame 31 is rotatably mounted on the mounting frame 21 via the first support shaft 34. A pair of anti-detachment wheels 32 are rotatably mounted on the first wheel frame 31 around a vertical axis. The pair of anti-detachment wheels 32 are unpowered wheels, arranged side by side in the left-right direction, and close to the left and right sides of the transport track 73. The pair of anti-detachment wheels 32 are distributed on the front side of the active drive wheel 23 and the driven drive wheel 24. Each anti-detachment wheel 32 has an anti-detachment groove 321 on its outer periphery to accommodate the transport track 73. By providing a pair of anti-detachment wheels 32 in the walking drive wheel assembly 20, the walking drive wheel assembly 20 is more reliably prevented from detaching upwards from the transport track 73, improving the reliability of the cooperation between the anti-slip movement mechanism and the transport track 73. Preferably, the anti-derailment wheel 32 is generally a conical wheel structure with its outer diameter gradually increasing from top to bottom. While forming an anti-derailment groove 731 that matches the transport track 73, it also plays the role of preventing derailment through its lower edge with a larger diameter.

[0052] Furthermore, such as Figure 4As shown, the adaptive wheel assembly of the walking drive wheel assembly 20 also includes a self-adjusting connecting plate 33. The self-adjusting connecting plate 33 is mounted on the mounting frame 21, and the first support shaft 34 is rotatably connected to the self-adjusting connecting plate 33 via bearings, that is, the first wheel frame 31 is mounted on the self-adjusting connecting plate 33. During the walking process, the self-adjusting connecting plate 33 can move within a certain range relative to the mounting frame 21, and the movement mode of the self-adjusting connecting plate 33 is left and right movement. Thus, during operation, when the transport track 73 deviates in the left and right direction due to its own shape changes and installation errors, the self-adjusting connecting plate 33 floats left and right within a certain range relative to the mounting frame 21, so that the pair of anti-detachment wheels 32 can automatically adjust their left and right positions according to the shape of the transport track 73, adapting to the left and right deviations of the transport track 73 caused by shape changes and errors, and ensuring good cooperation between the pair of anti-detachment wheels 32 and the transport track 73.

[0053] Preferably, the connection structure between the mounting bracket 21 and the self-adjusting connecting plate 33 can be varied; it can be connected by a hinge or by a linear slide rail assembly 35. In this embodiment, for example... Figure 4 As shown, the adaptive wheel assembly of the walking drive wheel set 20 also includes a linear slide rail assembly 35 disposed between the mounting frame 21 and the self-adjusting connecting plate 33. The linear slide rail assembly 35 includes a linear slide rail extending straight along a direction perpendicular to the moving direction of the mobile frame 10, and a slider that slides in cooperation with the linear slide rail. The linear slide rail is fixed to the top surface of the mounting frame 21, and the slider is fixed to the bottom surface of the self-adjusting connecting plate 33. Using the linear slide rail assembly 35 to achieve the self-movement of a pair of anti-detachment wheels 32 in the left and right directions is low in cost and high in precision, and has good economic benefits.

[0054] Furthermore, such as Figure 4 As shown, the adaptive wheel assembly of the walking drive wheel assembly 20 also includes a clamp 37 located at the upper and / or lower end of the bearing and fixed to the first support shaft 34. An elastic component or washer is provided between the clamp 37 and the bearing, and the elastic component or washer is sleeved on the first support shaft 34. The elastic component can be a spring. The elastic component or washer provides a certain redundancy in the vertical direction, allowing the active drive wheel 23 and the driven drive wheel 24 to adapt well to the undulations of the transport track 73.

[0055] Furthermore, such as Figure 4 and Figure 5As shown, the limiting wheel 36 in the adaptive wheel set is rotatably mounted on the first wheel frame 31 around a horizontal axis. The limiting wheel 36 is attached to the top of the transport track 73, and the central axis of the limiting wheel 36 is perpendicular to the central axis of the anti-slip wheel 32. The active drive wheel 23 and the driven drive wheel 24 are distributed sequentially with the limiting wheel 36 along the moving direction of the moving frame 10, that is, the limiting wheel 36 is located in front of the active drive wheel 23 and the driven drive wheel 24. During the movement of the anti-slip moving mechanism, the pair of anti-slip wheels 32 and the limiting wheel 36 cooperate to perform the following functions. 1. To enable the active drive wheel 23 and the driven drive wheel 24 to adapt well to the undulations of the transport track 73: When the anti-slip moving mechanism passes the higher position of the transport track 73, the limiting wheel 36 abuts against the top of the transport track 73, so that the active drive wheel 23 and the driven drive wheel 24 are reliably engaged with the transport track 73; when the anti-slip moving mechanism passes the lower position of the transport track 73, a pair of anti-detachment wheels 32 prevent the active drive wheel 23 and the driven drive wheel 24 from disengaging from the transport track 73, so that the active drive wheel 23 and the driven drive wheel 24 are always reliably engaged with the transport track 73, at which time the limiting wheel 36 is suspended above the top of the transport track 73; thus, through the combined action of the anti-detachment wheels 32 and the limiting wheels 36, the active drive wheel 23 and the driven drive wheel 24 can adapt well to the undulations of the transport track 73. 2. When the anti-slip moving mechanism brakes suddenly, it has a certain inertial force, which will cause the anti-slip moving mechanism to lurch forward. At this time, the limit wheel 36 abuts against the top of the transport track 73, which effectively prevents the anti-slip moving mechanism from lurching forward and lifting its tail when braking suddenly, increasing stability and reducing bouncing during braking.

[0056] Furthermore, such as Figure 5 As shown, the walking drive wheel assembly 20 also includes a first walking wheel 40 rotatably mounted on the mounting frame 21 about a horizontal axis. The first walking wheel 40 is attached to the top of the transport track 73 and is distributed behind the active drive wheel 23 and the driven drive wheel 24. The first walking wheel 40 is a non-powered wheel, which improves the stability of the walking drive wheel assembly 20 as it moves along the transport track 73.

[0057] Furthermore, such as Figure 2 and Figure 3As shown, the anti-slip moving mechanism also includes three sets of walking wheel sets 50, and the walking drive wheel sets 20 and the three sets of walking wheel sets 50 are arranged in a rectangular pattern. The moving frame 10 is roughly a rectangular frame structure. The walking drive wheel sets 20 and the three sets of second walking wheel sets 50 are respectively set at the four corners of the moving frame 10, so that the anti-slip moving mechanism is stably and movably installed on a pair of side-by-side transport tracks 73. When the walking drive wheel sets 20 are installed at the front end of the moving frame 10, the walking drive wheel sets 20 apply a pulling force to the moving frame 10, pulling the moving frame 10 forward along the transport track 73; when the walking drive wheel sets 20 are installed at the rear end of the moving frame 10, the walking drive wheel sets 20 apply a pushing force to the moving frame 10, pushing the moving frame 10 forward along the transport track 73.

[0058] Preferably, the drive wheel set 20 is located at the front end of the outer side of the mobile frame 10; of the three sets of drive wheels 50, one set is located at the rear end of the outer side of the mobile frame 10, and the other two sets are located at the front and rear ends of the inner side of the mobile frame 10, respectively. In this way, the drive wheel set 20 pulls the mobile frame 10 forward, resulting in more stable performance; simultaneously, the location of the mobile frame 10 on the outer side provides a larger turning radius at the drive wheel set 20, allowing the mobile frame 10 to navigate corners more smoothly and avoiding jamming during turns.

[0059] Furthermore, such as Figure 2 and Figure 3 As shown, each set of traveling wheels 50 includes a second wheel frame 51 fixed to the mobile frame 10 and a second traveling wheel 53 rotatably mounted on the second wheel frame 51. The second traveling wheel 53 is attached to the top of the transport track 73. The bottom of the first traveling wheel 40 and the bottom of the second traveling wheel 53 are at the same height and distributed on the same horizontal plane to ensure the stability of the anti-slip moving mechanism. Each set of traveling wheels 50 also includes two pairs of guide wheels 52, front and rear. The guide wheels 52 are rotatably mounted on the second wheel frame 51 around a vertical axis. Two of the guide wheels 52 in each pair are arranged side-by-side and attached to the left and right sides of the transport track 73. Preferably, the bottom of the guide wheel 52 is fixed with a wheel protrusion ring, which is located close to the bottom of the transport track 73 to more reliably prevent the second traveling wheel set 50 from detaching from the transport track 73, thereby more reliably avoiding derailment.

[0060] Furthermore, since the aforementioned anti-slip movement mechanism has only one wheel set (walking drive wheel set 20) in its walking drive wheel set 20, when the anti-slip movement mechanism crosses the turning or curved structure of the transport track 73, the structure of the anti-slip movement mechanism will not form a triangular clamping point, and no lateral force will be generated. This avoids jamming or even derailment of the anti-slip movement mechanism, improving its stability when crossing the turning or curved structure of the transport track 73. Thus, this application can smoothly cross the turns of closed or curved tracks and adapt to the non-straightness problem caused by indirect errors in ultra-long straight tracks, exhibiting good adaptive performance.

[0061] Furthermore, the active drive wheel 23, driven drive wheel 24, anti-detachment wheel 32, limiting wheel 36, first traveling wheel 40, guide wheel 52, and second traveling wheel 53 are all rubber-coated wheels, and the transport track 73 is a metal track. The active drive wheel 23 and driven drive wheel 24 each include a concave wheel body with a fitting groove 25 and a rubber coating covering the outer periphery of the concave wheel body; the concave wheel body is a metal component. The anti-detachment wheel 32, limiting wheel 36, first traveling wheel 40, guide wheel 52, and second traveling wheel 53 each include a wheel body and a rubber coating covering the outer periphery of the wheel body; the wheel body is a metal component. The metal concave wheel body ensures the structural strength of the active drive wheel 23 and driven drive wheel 24, and the metal wheel body ensures the structural strength of the anti-detachment wheel 32, limiting wheel 36, first traveling wheel 40, guide wheel 52, and second traveling wheel 53. Meanwhile, the rubber coating on each wheel increases the friction between the wheel and the transport track 73, improving the anti-slip effect. Preferably, the material of the rubber coating is any one of polymer materials, nylon, rubber, and silicone, such as PU (polyurethane), POM (polyoxymethylene), ABS resin, PC (polyamide), etc.

[0062] Furthermore, such as Figure 4 and Figure 5As shown, the anti-slip moving mechanism also includes an adjustment frame 80 connected between the moving frame 10 and the mounting frame 21. The adjustment frame 80 is used to adjust the left and right position and the front and back position of the mounting frame 21 relative to the moving frame 10, so as to realize the detachable connection of the entire walking drive wheel set 20, which facilitates the overall disassembly and assembly of the walking drive wheel set 20, and also allows the walking drive wheel set 20 to adapt to the installation error of other tooling in the anti-slip moving mechanism. Preferably, the adjusting frame 80 includes a first fixing plate 81 extending laterally, a second fixing plate 82 extending longitudinally, a first fastening bolt 83 fixing the first fixing plate 81 to the movable frame 10, and a second fastening bolt 84 fixing the second fixing plate 82 to the first fixing plate 81. The first fixing plate 81 has a first adjusting groove 85 for accommodating the first fastening bolt 83 and a second adjusting groove 86 for accommodating the second fastening bolt 84. The mounting frame 21 is rotatably mounted on the second fixing plate 82. Of the first adjusting groove 85 and the second adjusting groove 86, one extends longitudinally along the moving direction of the movable frame 10, and the other extends laterally in a direction perpendicular to the moving direction of the movable frame 10. In this embodiment, the first adjusting groove 85 extends laterally, and the second adjusting groove 86 extends longitudinally. Thus, the left-right position of the first fixing plate 81 relative to the movable frame 10 and the longitudinal position of the second fixing plate 82 relative to the first fixing plate 81 can be adjusted, thereby adjusting the left-right and longitudinal positions of the mounting frame 21, which in turn adjusts the overall left-right and longitudinal positions of the walking drive wheel assembly 20.

[0063] Preferably, such as Figure 4 As shown, the walking drive wheel set 20 also includes a second support shaft 210 fixed to the mounting bracket 21. The second support shaft 210 extends vertically and is rotatably mounted on the second fixed plate 82 via bearings.

[0064] like Figure 2 and Figure 3 As shown, the present invention also provides a sorting cart, including a conveying assembly and the aforementioned anti-slip movement mechanism. The conveying assembly includes a conveying drive source 61, a driving conveyor roller and a driven conveyor roller arranged side by side, and a conveyor belt 62 sleeved around the outer periphery of the driving and driven conveyor rollers; the conveying drive source 61 is fixedly mounted on a mobile frame 10, and the driving and driven conveyor rollers are rotatably mounted on the mobile frame 10. Thus, by applying the aforementioned anti-slip movement mechanism to a sorting cart in the logistics sorting field, the movement stability of the sorting cart is improved.

[0065] like Figure 9As shown, the present invention also provides a sorting system, including a fixed frame 71, a feeding platform 72 for conveying objects toward the fixed frame 71, a first sorting trolley that is vertically mounted on the fixed frame 71, several transport tracks 73 that are all fixed to the fixed frame 71 and arranged vertically, a second sorting trolley 74 that is movably mounted on the transport tracks 73, several material discharge chutes 75 fixed to the fixed frame 71, and receiving devices 76 distributed on the outside of the fixed frame 71. The first sorting trolley can move back and forth between the feeding platform 72 and each layer of transport tracks 73, the second sorting trolley 74 can move back and forth between the first sorting trolley and the material discharge chutes 75, and the receiving devices 76 are provided with several receiving frames that correspond one-to-one with the material discharge chutes 75. The first sorting trolley is the sorting trolley as described above. In this way, staff or robots only need to place the sorted goods on the feeding platform 72. The feeding platform 72 transports the goods on it toward the fixed frame 71 and onto the first sorting cart. The first sorting cart moves up and down to the transport track 73 corresponding to the target receiving frame. The first sorting cart delivers the goods on it to the second sorting cart 74. The second sorting cart 74 then moves along the transport track 73 to the target receiving frame. The second sorting cart 74 unloads the goods, and the goods slide down the drop chute 75 into the target receiving frame, completing one sorting of the goods.
