Abstract
Description
Technical Field
[0001] This utility model relates to the field of bogie transportation technology, and in particular to an AGV trolley. Background Technology
[0002] In the field of rail transit, AGVs can be used to transport bogies. The AGV is equipped with a pushing device on its body to push the bogies. The movement of the body can drive the bogies to move. The pushing devices are usually installed in pairs on the body to drive the bogies to move in two opposite directions and to achieve braking.
[0003] In related technologies, the pushing device pushes the bogie by contacting the wheel hub or axle of the bogie. That is, the two pushing devices contact the wheel hub or axle on one side respectively. However, the distance between the two wheel hubs or axles of the bogie is relatively far, so the pushing ends of the two pushing devices are also far apart. As a result, the vehicle body size required to install the two pushing devices needs to be large, which makes the transportation and storage of AGV vehicles inconvenient. Utility Model Content
[0004] This application provides an AGV (Automated Guided Vehicle) that improves upon the technical problem in related technologies where the vehicle body size required to install two push devices is large, leading to inconvenience in the transportation and storage of the AGV.
[0005] This application provides an AGV (Automated Guided Vehicle) for pushing a bogie, the bogie having a crossbar structure, with a clamping plate at the intersection of the crossbar structure, and the AGV includes:
[0006] Vehicle body;
[0007] A pushing device is installed on the vehicle body. The pushing device includes two pushing mechanisms, which are respectively disposed on both sides of the clamp and contact the clamp.
[0008] When the vehicle body is moving, at least one of the pushing mechanisms can push the bogie by contacting the clamp; when the vehicle body is braking, both pushing mechanisms can brake the bogie together by contacting the clamp.

The mounting component is fixedly connected to the vehicle body, and the pushing component is movably mounted on the mounting component. The pushing component is used to contact the clamping plate. The driving component can drive the pushing component to move relative to the mounting component, allowing the pushing component to extend outside the mounting component or retract inside the mounting component. When the pushing component extends outside the mounting component, it can contact the clamping plate.
[0010] In some embodiments, the push component is hinged to the mounting component, and the drive component is capable of driving the push component to rotate relative to the mounting component so that the push component can extend outside the mounting component or retract into the mounting component.
[0011] In some embodiments, the drive assembly includes a drive member and a pusher member, the drive member being drively connected to the pusher member, the pusher member being in contact with the push assembly, and the drive member being capable of driving the pusher member to move, thereby causing the push assembly to rotate relative to the mounting assembly.
[0012] In some embodiments, the pusher has an inclined surface, the push assembly is capable of contacting the inclined surface, and the inclined surface is capable of relative movement with the push assembly when the drive member drives the pusher to move, so that the push assembly rotates relative to the mounting assembly.
[0013] In some embodiments, the pusher has a horizontally arranged abutment surface connected to the inclined surface; when the drive member drives the pusher to move, the push assembly can move between the inclined surface and the abutment surface, and when the push assembly is located on the abutment surface, the abutment surface supports the push assembly.
[0014] In some embodiments, the pushing component includes a rotating part, a pushing part, and a contact part. One end of the rotating part is hinged to the mounting component via a pivot. The pushing part is located at the end of the rotating part away from the pivot. The contact part is located on the side of the rotating part and contacts the pushing member. The pushing part is used to contact the clamping plate.
[0015] In some embodiments, the contact portion is rotatably disposed on the rotating portion.
[0016] In some embodiments, the pushing part is rotatably disposed on the rotating part.
[0017] In some embodiments, the mounting assembly includes a fixed bracket and a mounting member mounted on the fixed bracket, the push assembly is hinged to the mounting member, and the drive assembly is capable of driving the push assembly to move relative to the mounting member so that the push assembly can extend out of the fixed bracket or retract into the fixed bracket, and when the push assembly extends out of the fixed bracket, the push assembly can contact the clamping plate.
[0018] In some embodiments, the mounting member includes a mounting portion and a stop portion, the push assembly is hinged to the mounting portion, and the stop portion is disposed on the top of the mounting portion; wherein, when the push portion contacts the clamping plate, the stop portion contacts the push portion to stop the push portion.
[0019] In some embodiments, the pusher is disposed within the fixed bracket, and the drive assembly passes through the fixed bracket to be drively connected to the pusher.
[0020] In some embodiments, the fixed bracket has two opposing sidewalls, each sidewall having a groove, and sliders on both sides of the pusher, the sliders slidingly engaging with the grooves on the same side.
[0021] The beneficial effects of this application are as follows:
[0022] In the AGV trolley provided in this application, since the two pushing mechanisms can be respectively located on both sides of the clamp and contact the clamp, that is, the pushing mechanism pushes the bogie to move by contacting the clamp. Since the size of the clamp is small and the distance between the two sides of the clamp is close, the distance between the two pushing mechanisms can also be close, so the size of the vehicle body can be smaller, so as to facilitate the transportation and storage of the AGV trolley.

[0038] Automated Guided Vehicles (AGVs) are a type of mobile robot and an important piece of equipment in the logistics systems of modern manufacturing enterprises. They are mainly used for storing and transporting various materials, providing an important guarantee for the flexibility, integration, and efficient operation of the system. They are usually powered by batteries and equipped with non-contact guidance devices. With the assistance of computer control and guidance devices, they can accurately reach their destination.
[0039] In the field of rail transit, AGVs can be used to transport bogies. The AGV is equipped with a pushing device on its body to push the bogies. The movement of the body can drive the bogies to move. The pushing devices are usually installed in pairs on the body to drive the bogies to move in two opposite directions and to achieve braking.
[0040] Please see Figure 1 In related technologies, the pushing device pushes the bogie 10 by contacting the wheel hub 11 or axle 12 of the bogie 10. That is, the two pushing devices contact the wheel hub 11 or axle 12 on one side respectively. However, the distance between the two wheel hubs 11 or axles 12 of the bogie 10 is relatively far, so the pushing ends of the two pushing devices are also far apart. As a result, the vehicle body size used to install the two pushing devices needs to be large, which makes the transportation and storage of AGV vehicles inconvenient.
[0041] In order to improve the problems in the related technologies to a certain extent, this application provides an AGV vehicle that allows the distance between the two pushing mechanisms to be set closer, thereby reducing the size of the vehicle body and facilitating the transportation and storage of the AGV vehicle.
[0042] The embodiments of this application will now be described with reference to the accompanying drawings:
[0043] Please see Figure 1This application provides an AGV trolley 20 for pushing a bogie 10. The bogie 10 has a crossbar structure 13, and a clamping plate 14 is provided at the intersection of the crossbar structures 13. The AGV trolley 20 provided in this application embodiment allows the distance between the two pushing mechanisms 22a to be set closer, thereby reducing the size of the vehicle body 21 and facilitating the transportation and storage of the AGV trolley 20.
[0044] The crossbar structure 13 is an important component connecting the left and right sides of the bogie 10. It typically consists of two long, interconnected rods and is located at the lower part of the suspension system. One end of the crossbar is connected to the car body 21, and the other end is connected to the wheel bracket. Its main function is to transmit steering forces and maintain vehicle stability. A clamping plate 14 is welded to the intersection of the crossbar structure 13 to improve its strength and stability. The crossbar structure 13 of the bogie 10 is existing technology, and its structure and principle will not be described in detail here.
[0045] Please see Figures 1-3 In this embodiment, the AGV trolley 20 includes a vehicle body 21 and a pushing device 22. The pushing device 22 is mounted on the vehicle body 21 and includes two pushing mechanisms 22a. The two pushing mechanisms 22a can be respectively disposed on both sides of the clamping plate 14 and contact the clamping plate 14.
[0046] When the car body 21 is moving, at least one pushing mechanism 22a can push the bogie 10 by contacting the clamping plate 14; when the car body 21 is braking, two pushing mechanisms 22a can brake the bogie 10 together by contacting the clamping plate 14.
[0047] It is understandable that the two pushing mechanisms 22a can be respectively located on both sides of the clamping plate 14 along the traveling direction of the bogie 10. For ease of description, this article refers to... Figure 2 and Figure 3 Taking the orientation of the pusher 22 as an example, the two pushers 22a can be respectively located on the left and right sides of the clamping plate 14. Of course, when the position of the pusher 22 changes, the orientation also changes accordingly.
[0048] When the bogie 10 needs to be pushed, the AGV trolley 20 is positioned below the bogie 10, with two pushing mechanisms 22a positioned on either side of the clamping plate 14. When the car body 21 moves to the right, the pushing mechanism 22a on the left contacts the clamping plate 14, allowing it to push the bogie 10 to the right. When the car body 21 stops moving, the pushing mechanism 22a on the right also contacts the clamping plate 14. In other words, both pushing mechanisms 22a clamp the clamping plate 14 together, thus braking the bogie 10 and preventing it from continuing to move due to inertia.
[0049] Similarly, when the car body 21 moves to the left, the push mechanism 22a on the right side contacts the clamping plate 14, so that the push mechanism 22a can push the bogie 10 to move to the left through the clamping plate 14. When the car body 21 stops moving, the push mechanism 22a on the left side also contacts the clamping plate 14. That is, the two push mechanisms 22a jointly clamp the clamping plate 14, so that they can jointly brake the bogie 10 and prevent the bogie 10 from continuing to move under inertia.
[0050] Therefore, one of the pushing mechanisms 22a can be selected to contact the clamping plate 14 as needed. The structures and working principles of the two pushing mechanisms 22a are completely identical. This article describes the pushing mechanism 22a on the left, and uses... Figure 4 and Figure 5 Taking the orientation in the middle as an example, the pushing mechanism 22a on the right can be described by analogy.
[0051] Please see Figures 1-3 In related technologies, the pushing mechanism 22a needs to contact the wheel hub 11 or axle 12 of the bogie 10 to push the bogie 10. However, the distance between the wheel hub 11 or axle 12 on both sides is relatively large, resulting in a large distance between the two pushing mechanisms 22a, and consequently, a larger vehicle body 21. In this embodiment, the two pushing mechanisms 22a push the bogie 10 by contacting both sides of the clamping plate 14. The distance between the left and right sides of the clamping plate 14 is much smaller than the distance between the wheel hub 11 or axle 12 on both sides. Therefore, the distance between the two pushing mechanisms 22a can be set closer, resulting in a smaller vehicle body 21, which facilitates the transportation and storage of the AGV trolley 20.
[0052] Please see Figure 4 and Figure 5 In some embodiments, the pushing mechanism 22a includes a driving component 100, a pushing component 200, and a mounting component 300. The mounting component 300 is fixedly connected to the vehicle body 21, and the pushing component 200 is movably mounted on the mounting component 300. The pushing component 200 is used to contact the clamping plate 14. The driving component 100 can drive the pushing component 200 to move relative to the mounting component 300, so that the pushing component 200 can extend outside the mounting component 300 or retract inside the mounting component 300. When the pushing component 200 extends outside the mounting component 300, the pushing component 200 can contact the clamping plate 14.
[0053] Since the pushing structure needs to contact the clamping plate 14 when pushing the bogie 10, and the AGV trolley 20 needs to pass under the bogie 10 when not pushing the bogie 10, the pushing mechanism 22a has a working state (e.g., Figure 5 (as shown) and non-working states (such as) Figure 4(As shown). When the pushing mechanism 22a is in working condition, the pushing structure needs to contact the clamping plate 14 to push the bogie 10. When the pushing mechanism 22a is not in working condition, the pushing structure needs to retract to avoid the cross bar, so as not to interfere with the passage of the AGV trolley 20 under the bogie 10.
[0054] When the bogie 10 needs to be pushed, the drive assembly 100 drives the push assembly 200 to move relative to the mounting assembly 300, so that the push assembly 200 extends out of the mounting assembly 300 to contact the clamping plate 14. After the push is completed, the drive assembly 100 drives the push assembly 200 to move relative to the mounting assembly 300, so that the push assembly 200 retracts into the mounting assembly 300, thereby not interfering with the AGV trolley 20 passing under the bogie 10.
[0055] In some embodiments, the push component 200 is hinged to the mounting component 300, and the drive component 100 is capable of driving the push component 200 to rotate relative to the mounting component 300 so that the push component 200 can extend out of the mounting component 300 or retract into the mounting component 300.
[0056] That is, the push component 200 extends outside the mounting component 300 or retracts inside the mounting component 300 by rotating. Please refer to [link / reference]. Figure 4 The driving component 100 drives the pushing component 200 to rotate clockwise relative to the mounting component 300, so that the pushing component 200 extends out of the mounting component 300, and also drives the pushing component 200 to rotate counterclockwise relative to the mounting component 300, so that the pushing component 200 retracts into the mounting component 300. Specifically, the pushing mechanism 22a can be set vertically in the working state to extend out of the mounting component 300, and can be set horizontally in the non-working state to retract into the mounting component 300.
[0057] Please see Figure 6 and Figure 7 In some embodiments, the drive assembly 100 includes a drive member 110 and a pusher member 120. The drive member 110 is drive-connected to the pusher member 120. The pusher member 120 contacts the push assembly 200. The drive member 110 can drive the pusher member 120 to move, so that the push assembly 200 rotates relative to the mounting assembly 300.
[0058] Since the driving member 110 is connected to the pushing member 120 and the pushing member 120 is in contact with the pushing component 200, the driving member 110 drives the pushing member 120 to move, and the pushing member 120 transmits the driving force to the pushing component 200 to push the pushing component 200 to rotate relative to the mounting component 300.
[0059] It should be noted that when the pushing component 200 is not subjected to any driving force, it is roughly horizontal under its own weight. Therefore, when the pushing component 200 needs to contact the clamping plate 14, the driving component 110 drives the pushing component 120 to move. The pushing component 120 transmits the driving force to the pushing component 200, so as to push the pushing component 200 to rotate relative to the mounting component 300 to a vertical position. After the pushing component 200 has finished pushing, the driving component 110 drives the pushing component 120 to move in the opposite direction, so that the driving force between the pushing component 120 and the pushing component 200 disappears, and the pushing component 200 returns to a horizontal position under its own weight.
[0060] In some embodiments, the pusher 120 has an inclined surface 121, and the pusher assembly 200 can contact the inclined surface 121. When the drive member 110 drives the pusher 120 to move, the inclined surface 121 can move relative to the pusher assembly 200 so that the pusher assembly 200 rotates relative to the mounting assembly 300.
[0061] When the driving member 110 drives the pushing member 120 to move, the inclined plane 121 can provide a thrust to the pushing component 200, causing the pushing component 200 to move along the inclined plane 121 and thus rotate to a vertical state relative to the mounting component 300; when the driving member 110 drives the pushing member 120 to move in the opposite direction, the thrust of the inclined plane 121 to the pushing component 200 disappears, and the pushing component 200 moves in the opposite direction along the inclined plane 121 under its own gravity and rotates to a horizontal state relative to the mounting component 300.
[0062] Specifically, the inclined plane 121 slopes downward from left to right. When the pusher is in a horizontal state, the pusher component 200 contacts the lowermost (right) end of the inclined plane 121. The drive member 110 drives the pusher component 120 to move to the right, thereby the inclined plane 121 pushes the pusher component 200 to rotate clockwise and move upward (left) along the inclined plane 121 until the pusher component 200 is in a vertical state. When the drive member 110 drives the pusher component 120 to move to the left, the pusher force of the inclined plane 121 on the pusher component 200 disappears. Under its own gravity, the pusher component 200 moves downward (right) along the inclined plane 121 and rotates relative to the mounting component 300 to a horizontal state.
[0063] The driving component 110 can be an electric push rod. The driving component 110 is located on the left side of the pusher 120, so that when the driving component 110 extends, it can drive the pusher 120 to move to the right, and when it retracts, it can drive the pusher 120 to move to the left.
[0064] In some embodiments, the pusher 120 has a horizontally arranged abutment surface 122 connected to the inclined surface 121; when the drive member 110 drives the pusher 120 to move, the pusher component 200 can move between the inclined surface 121 and the abutment surface 122, and when the pusher component 200 is located on the abutment surface 122, the abutment surface 122 supports the pusher component 200.
[0065] Since the push component 200 will rotate counterclockwise to a horizontal state under its own gravity when it loses driving force, and the drive component 110 will stop driving when the push component 200 rotates to a vertical state, in order to keep the push component 200 in a vertical state and thus keep it in contact with the clamping plate 14, a stop surface 122 is provided on the push component 120 to support and limit the push component 200, so that the push component 200 remains in a vertical state.
[0066] Specifically, the abutment surface 122 is located on the left side of the inclined plane 121. When the driving member 110 drives the pushing member 120 to move to the right, the pushing component 200 can move to the left along the inclined plane 121 to rotate to a vertical state. After the pushing component 200 rotates to a vertical state, the driving member 110 will continue to drive the pushing member 120 to move to the right, so that the pushing component 200 continues to move to the left to the abutment surface 122, so that the abutment surface 122 supports and limits the pushing component 200. When the driving member 110 drives the pushing member 120 to move to the left, the pushing component 200 first moves to the right along the abutment surface 122 to the inclined plane 121, and then moves to the right along the inclined plane 121 under its own gravity and rotates to a horizontal state.
[0067] Because there is an angle between the abutting surface 122 and the inclined surface 121, the pushing component 200 can move smoothly between the abutting surface 122 and the inclined surface 121, and the abutting surface 122 and the inclined surface 121 can be rounded.
[0068] Please see Figures 6-8 In some embodiments, the pusher 120 has a mounting groove 123, and a portion of the pusher component 200 is located within the mounting groove 123, allowing the pusher component 200 to rotate within the mounting groove 123. An inclined surface 121 and a stop surface 122 are provided on the outer surface of the mounting groove 123, and both sides of the pusher component 200 are provided with inclined surfaces 121 and stop surfaces 122. Since the pusher component 200 moves along the inclined surface 121 during rotation, the presence of inclined surfaces 121 on both sides of the pusher component 200 makes its rotation more stable. Furthermore, the presence of stop surfaces 122 on both sides of the pusher component 200 provides more stable support, allowing the pusher component 200 to remain vertical, thus ensuring the effective pushing of the bogie 10.
[0069] Furthermore, the driving end of the driving component 110 is also located in the mounting groove 123 and connected to the pusher 120. The mounting groove 123 has two oppositely arranged sides. The driving end is fixedly connected to the two sides through the connecting plate 111, thereby ensuring a stable connection between the driving component 110 and the pusher 120 and guaranteeing the transmission effect.
[0070] In some embodiments, the pushing component 200 includes a rotating part 210, a pushing part 220, and a contact part 230. One end of the rotating part 210 is hinged to the mounting component 300 via a pivot 211. The pushing part 220 is located at the end of the rotating part 210 away from the pivot 211. The contact part 230 is located on the side of the rotating part 210 and contacts the pusher 120. The pushing part 220 is used to contact the clamping plate 14.
[0071] Since the pushing part 220 is located at the end of the rotating part 210 away from the rotating shaft 211, the pushing part 220 can be regarded as an extension of the rotating part 210 in the rotational radial direction. Therefore, the rotation of the rotating part 210 relative to the mounting assembly 300 can drive the pushing part 220 to switch between horizontal and vertical states to achieve contact with the clamping plate 14. The contact part 230 is located on the side of the rotating part 210, so it can contact the inclined surface 121 and the abutment surface 122 to achieve the transmission of driving force.
[0072] Of course, since the push component 200 has inclined surfaces 121 and abutment surfaces 122 on both sides, there are also two contact parts 230. The two contact parts 230 are respectively located on both sides of the rotating part 210, and the contact parts 230 are in contact with the inclined surfaces 121 and abutment surfaces 122 on the same side.
[0073] In some embodiments, the contact portion 230 is rotatably disposed on the rotating portion 210.
[0074] Since the contact portion 230 needs to move between the inclined surface 121 and the abutting surface 122, in order to make the movement of the contact portion 230 on the inclined surface 121 and the abutting surface 122 smoother and thus improve the driving effect on the rotating portion 210, the contact portion 230 is rotatably disposed on the rotating portion 210. This makes the friction between the contact portion 230 and the inclined surface 121 and the abutting surface 122 rolling friction, thereby reducing frictional resistance and making the movement of the contact portion 230 on the inclined surface 121 and the abutting surface 122 smoother.
[0075] Specifically, the contact part 230 can be a roller, and a fixed shaft can be fixedly installed on the rotating part 210. The contact part 230 is rotatably mounted on the fixed shaft, thereby realizing the fixed installation of the contact part 230 on the rotating part 210.
[0076] In some embodiments, the pushing part 220 is rotatably disposed on the rotating part 210.
[0077] Since the pushing part 220 is rotatably disposed on the rotating part 210, when the pushing part 220 contacts the clamping plate 14, it can reduce the friction between the pushing part 220 and the clamping plate 14 and make the clamping plate 14 more flexible under force, thereby better protecting the clamping plate 14 and reducing the damage to the clamping plate 14. Specifically, the pushing part 220 can be a roller.
[0078] In some embodiments, the mounting assembly 300 includes a fixed bracket 310 and a mounting member 320 mounted on the fixed bracket 310. The pushing assembly 200 is hinged to the mounting member 320. The driving assembly 100 is capable of driving the pushing assembly 200 to move relative to the mounting member 320, so that the pushing assembly 200 can extend out of the fixed bracket 310 or retract into the fixed bracket 310. When the pushing assembly 200 extends out of the fixed bracket 310, the pushing assembly 200 can contact the clamping plate 14.
[0079] Mounting component 320 can be fixedly connected to fixed bracket 310 or directly fixedly connected to vehicle body 21. With mounting component 320 fixed, pushing component 200 can rotate relative to mounting component 320. Since pushing component 200 can extend outside or retract inside fixed bracket 310, that is, when not in operation, pushing component 200 can be stored inside fixed bracket 310. Therefore, fixed bracket 310 can protect pushing component 200 and reduce damage to it.
[0080] Please see Figure 6 and Figure 7 In some embodiments, the mounting member 320 includes a mounting portion 321 and a stop portion 322, the push assembly 200 is hinged to the mounting portion 321, and the stop portion 322 is disposed on the top of the mounting portion 321; wherein, when the push portion 220 contacts the clamping plate 14, the stop portion 322 contacts the push portion 220 to stop the push portion 220.
[0081] When the pushing part 220 is in a vertical position, a stop part 322 is provided to further maintain the vertical position of the pushing part 220. The rotating part 210 can be hinged to the left side of the mounting part 321, and the stop part 322 is provided at the top right side of the mounting part 321. When the pushing part 220 contacts the clamping plate 14, the stop part 322 contacts the pushing part 220, thereby restricting the pushing part 220 from continuing to rotate clockwise, so that the pushing part 220 remains in a vertical position, thereby ensuring the pushing effect on the bogie 10.
[0082] Specifically, the mounting part 321 can be located inside the fixed bracket 310, and the stop part 322 can be located outside the fixed bracket 310, and the stop part 322 can be directly fixedly connected to the vehicle body 21. The stop part 322 and the fixed bracket 310 can be fixedly connected to the vehicle body 21 by bolts. Of course, in order to make the installation of the drive component 110 on the vehicle body 21 more stable, the vehicle body 21 is also provided with a mounting bracket 330, and the drive component 110 is installed in the mounting bracket 330.
[0083] Please see Figure 8 In some embodiments, the pusher 120 is disposed within the fixed bracket 310, and the drive assembly 100 passes through the fixed bracket 310 to be connected to the pusher 120 in a transmission manner.
[0084] Since the pusher 120 is in contact with the pusher assembly 200, the pusher assembly 200 can retract into the fixed bracket 310. Therefore, the pusher 120 can also be disposed in the fixed bracket 310, so that the fixed bracket 310 can also protect the pusher 120 to reduce the damage to the pusher 120.
[0085] In some embodiments, the fixed bracket 310 has two oppositely arranged side walls 311, each of which has a groove 312. The pusher 120 has sliders 124 on both sides, and the sliders 124 slide in cooperation with the grooves 312 on the same side.
[0086] During the process of driving the pusher 120 to move, the slider 124 slides on the same side of the groove 312, which can provide guidance for the movement of the pusher 120, making the movement of the pusher 120 more stable, thereby making the thrust on the pusher 200 more stable, so that the pusher 200 can rotate smoothly.
[0087] In the AGV trolley 20 provided in this application, since the two pushing mechanisms 22a can be respectively disposed on both sides of the clamping plate 14 and contact the clamping plate 14, that is, the pushing mechanism 22a pushes the bogie 10 to move by contacting the clamping plate 14. Since the size of the clamping plate 14 is small and the distance between the two sides of the clamping plate 14 is close, the distance between the two pushing mechanisms 22a can also be close. Therefore, the size of the vehicle body 21 used to install the two pushing mechanisms 22a can be smaller, and thus the overall size of the AGV trolley 20 can be smaller, so as to facilitate the transportation and storage of the AGV trolley 20.
