Description

[0001] This utility model relates to the field of tractor technology, specifically to a coupling device and a transport equipment. Background Technology

[0002] Tractors play a vital role in the transportation industry, as they are used to tow or pull other vehicles, such as trailers. In use, the trailer is connected to the tractor, and cargo such as containers is placed on the trailer.

[0003] In related technologies, a pin is usually installed on the tractor unit, and a hook is installed on the trailer unit into which the pin can be inserted. When connecting the trailer unit to the tractor unit, the operator needs to move the trailer unit to the position of the tractor unit and manually insert the pin into the hook to hook the trailer unit onto the tractor unit. This results in low hooking efficiency between the tractor unit and the trailer unit. Utility Model Content

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art based on the embodiments of the present utility model are within the protection scope of the present utility model.

[0039] Reference Figure 1 , Figure 5 and Figure 6 As shown, this embodiment provides a coupling device 10 for coupling a tractor 20 and a trailer 30.

[0040] The tractor 20 can be an Automated Guided Vehicle (AGV), which is coupled to the trailer 30 via the coupling device 10 so that the trailer 30 can move under the drive of the tractor 20.

[0041] Specifically, the mounting device 10 includes: a first mounting component 1, a second mounting component 2, and a first detection component 3.

[0042] The first coupling assembly 1 is used to connect to the tractor 20. The second coupling assembly 2 is used to connect to the trailer 30, and the first coupling assembly 1 can be matched and coupled with the second coupling assembly 2.

[0043] Specifically, the first detection component 3 is mounted on the tractor 20 and electrically connected to the controller of the tractor 20. The first detection component 3 is used to detect the alignment status between the first coupling assembly 1 and the second coupling assembly 2 as the tractor 20 moves towards the trailer 30. The controller is used to control the coupling of the first coupling assembly 1 and the second coupling assembly 2 based on the detection result of the first detection component 3, thereby achieving coupling between the tractor 20 and the trailer 30. The alignment status between the first coupling assembly 1 and the second coupling assembly 2 includes: alignment and misalignment (i.e., misalignment).

[0044] For example, the controller may be the main controller of the tractor 20, or it may be an additional controller set up for attaching the first coupling component 1 and the second coupling component 2.

[0045] The coupling device provided in this embodiment, by setting a first coupling component 1, a second coupling component 2, and a first detection component 3, connects the first coupling component 1 to the tractor 20 and the second coupling component 2 to the trailer 30, so that the first coupling component 1 can be matched and coupled with the second coupling component 2; the first detection component 3 is set on the tractor 20 and electrically connected to the controller of the tractor 20, so that the first detection component 3 is used to detect the alignment state between the first coupling component 1 and the second coupling component 2 during the process of the tractor 20 moving towards the trailer 30, and the controller is used to control the first coupling component 1 and the second coupling component 2 to be coupled according to the detection result of the first detection component 3, so as to realize the coupling between the tractor 20 and the trailer 30. In this way, during the coupling process between the tractor 20 and the trailer 30, the first detection component 3 can detect the alignment status between the first coupling component 1 and the second coupling component 2, and the controller can automatically control the coupling of the first coupling component 1 and the second coupling component 2 according to the detection result of the first detection component 3. Compared with the solution of manually coupling the tractor and the trailer, this utility model can realize the automated coupling of the tractor 20 and the trailer 30 to a certain extent. The coupling is simple and reliable, and no manual intervention is required during the coupling process, saving manpower and the time required for waiting for manual intervention before coupling. At the same time, there is no need to add an additional module to confirm the coupling effect of the first coupling component 1 and the second coupling component 2.

[0046] In some embodiments, refer to Figure 1 , Figure 2 and Figure 6 As shown, the first mounting assembly 1 includes a mounting member 11 and a driving member 12. The driving member 12 is connected to the mounting member 11 and is used to drive the mounting member 11 to move relative to the second mounting assembly 2 until it is mounted with the second mounting assembly 2. A first detection member 3 is used to detect the alignment state between the mounting member 11 and the second mounting assembly 2. The driving member 12 is electrically connected to a controller, which controls the driving member 12 to drive the mounting member 11 to move according to the detection result of the first detection member 3, so that the mounting member 11 is mounted with the second mounting assembly 2.

[0047] With this setup, the alignment status of the coupling piece 11 and the second coupling assembly 2 is detected by the first detection element 3. For example, when the coupling piece 11 is detected to be aligned with the second coupling assembly 2, the controller can control the drive element 12 to drive the coupling piece 11 to move and engage with the second coupling assembly 2, thereby realizing the coupling of the tractor 20 and the trailer 30. The coupling process is flexible and convenient, and the coupling efficiency is high.

[0048] In practice, the drive unit 12 can be connected to the tractor 20.

[0049] In some embodiments, refer to Figure 3 , Figure 4 and Figure 6 As shown, the second coupling assembly 2 has a coupling section 211 and a main body section 212 connected to the coupling section 211. The coupling section 211 can be coupled to the coupling member 11. In the direction of movement of the tractor 20 toward the trailer 30, the main body section 212 is located on the side of the coupling section 211 facing the tractor 20. The first detection element 3 is used to identify the main body section 212 and the coupling section 211 to determine the alignment state between the coupling member 11 and the coupling section 211. The controller is used to control the movement of the tractor 20 according to the detection result of the first detection element 3, and to control the drive element 12 to drive the coupling member 11 to move so that the coupling member 11 is coupled to the coupling section 211. The direction of movement of the tractor 20 toward the trailer 30 can be, for example, Figure 5 The direction from left to right in the middle.

[0050] With this configuration, when the first detection element 3 identifies the main body segment 212, it indicates that the coupling element 11 and the coupling segment 211 are in a pre-alignment state. At this time, the controller can control the tractor 20 to decelerate and the drive element 12 to temporarily stop driving the coupling element 11. When the first detection element 3 identifies the coupling segment 211, it indicates that the coupling element 11 and the coupling segment 211 are in an alignment state. At this time, the controller controls the tractor 20 to stop and controls the drive element 12 to drive the coupling element 11 to move so that the coupling element 11 and the coupling segment 211 can be coupled. This can prevent the tractor 20 from moving too fast and affecting the accurate identification of the coupling segment 211, thus helping to ensure the accurate coupling of the tractor 20 and the trailer 30.

[0051] In some embodiments, the first detection element 3 includes a first distance sensor, which is used to detect the distance between the first distance sensor and the second mounting component 2. The distance value corresponding to the first distance sensor detecting the main body segment 212 is different from the distance value corresponding to the first distance sensor detecting the mounting segment 211, so as to determine the alignment state between the mounting component 11 and the mounting segment 211 based on the detection result of the first distance sensor.

[0052] With this configuration, the controller can determine whether the first detection element 3 has detected the main body segment 212 or the coupling segment 211 by obtaining the distance value detected by the first detection element 3. This makes it convenient for the controller to control the tractor 20 to slow down and control the coupling element 11 to temporarily stop moving when the main body segment 212 is detected, and to control the tractor 20 to stop moving and control the coupling element 11 to move to match and engage with the coupling segment 211 when the coupling segment 211 is detected. This configuration is flexible and convenient to use.

[0053] For example, a first distance sensor can be used to detect the distance between the first distance sensor and the second coupling assembly 2 along the height direction of the tractor 20 (specifically... Figure 2 and Figure 6 The vertical distance in the up and down direction.

[0054] Of course, in other implementations, the first detection component 3 can also be a camera, etc.

[0055] In some embodiments, the first distance sensor includes a photoelectric sensor, so that the distance between the first detection element 3 and the second mounting component 2 can be detected through the photoelectric effect.

[0056] Of course, the first distance sensor can also be a proximity switch, etc.

[0057] In some embodiments, refer to Figure 3 , Figure 4 and Figure 6 As shown, the mounting segment 211 has a mounting cavity 213. The controller is used to control the drive unit 12 to drive the mounting member 11 to move toward the mounting cavity 213 and extend into the mounting cavity 213 when the first detection unit 3 detects the mounting segment 211, so that the mounting member 11 is mounted with the mounting segment 211.

[0058] With this configuration, when the first detection element 3 detects the coupling section 211, the controller can control the drive element 12 to drive the coupling element 11 to move and extend into the coupling cavity 213, thereby achieving coupling of the coupling element 11 in the coupling cavity 213, thus coupling the trailer 30 to the tractor 20. The coupling of the two is simple and reliable.

[0059] When the tractor 20 pulls the trailer 30 to a designated position, the controller can control the drive unit 12 to drive the coupling 11 to retract away from the coupling cavity 213, so as to detach the tractor 20 from the trailer 30.

[0060] Specifically, the movement of the connector 11 can be a movement (e.g., along a path). Figure 2 and Figure 6 It can be moved up or down, or it can be rotated.

[0061] For example, at least one side of the mounting cavity 213 may have a through hole 214 so that the mounting member 11 can be inserted into the mounting cavity 213 through the through hole 214 under the drive of the drive member 12, or removed from the mounting cavity 213 through the through hole 214.

[0062] In some embodiments, refer to Figure 2 and Figure 6The hook-up component 11 includes a hook-up insert shaft, which facilitates the hook-up component 11 to be hooked up with the hook-up cavity 213 to achieve the hook-up of the tractor 20 and the trailer 30, making it convenient to use.

[0063] Of course, the mounting bracket 11 can also be a hook, etc.

[0064] For example, when the hook 11 moves, the drive 12 can be a push rod motor or a drive cylinder, etc.

[0065] In some embodiments, refer to Figure 2 and Figure 6 As shown, the coupling device 10 also includes a second detection element 4 for mounting on the tractor 20. The second detection element 4 is used to detect the insertion length of the coupling element 11 in the coupling cavity 213. The second detection element 4 is electrically connected to the controller, and the controller is also used to control the working state of the drive element 12 according to the detection result of the second detection element 4.

[0066] With this configuration, for example, when the second detection element 4 detects that the insertion length of the hook-up piece 11 in the hook-up cavity 213 reaches a preset length threshold, indicating that the hook-up piece 11 is inserted into the hook-up cavity 213, the controller can control the drive element 12 to drive the hook-up piece 11 to stop moving, so as to maintain the hook-up piece 11 in the hook-up cavity 213, thereby realizing the automated control of the movement state of the hook-up piece 11, which can further improve the convenience of hooking the hook-up piece 11 in the hook-up cavity 213, and further improve the hook-up efficiency of the tractor 20 and the trailer 30.

[0067] In some embodiments, the second detection element 4 includes a second distance sensor. The second distance sensor is located on the movement path of the hanger 11 and is used to detect the distance between the second distance sensor and the hanger 11. The controller is used to control the drive element 12 to stop working when the distance value detected by the second distance sensor reaches a preset distance threshold.

[0068] In this way, the insertion length of the hanger 11 in the hanger cavity 213 can be determined by the distance detection result of the second distance sensor. The insertion length detection of the hanger 11 is simple and convenient.

[0069] Of course, in other embodiments, the second detection element 4 can be a camera, etc.

[0070] In some embodiments, the second distance sensor includes a proximity switch, which enables non-contact detection of the distance between the second distance sensor and the mounting piece 11. This can, to some extent, prevent the second distance sensor from being damaged by accidental collision with the mounting piece 11, thereby providing good protection for both the second distance sensor and the mounting piece 11.

[0071] Of course, in other embodiments, the second distance sensor may also be a photoelectric sensor or the like.

[0072] In some embodiments, refer to Figure 2 and Figure 6 As shown, a limiting engagement part 111 can be provided at the position of the second distance sensor corresponding to the hanger 11, so that the second distance sensor can be used to detect the distance between the second distance sensor and the limiting engagement part 111, thereby determining the length of the hanger 11 extending into the hanger cavity 213.

[0073] In some embodiments, refer to Figure 3 , Figure 4 and Figure 6 As shown, the second attachment assembly 2 includes an attachment body 21 and a limiting component 22. The attachment body 21 is used to connect to the trailer 30, and the attachment body 21 can be matched and attached to the first attachment assembly 1. The limiting component 22 is disposed on the attachment body 21, and the limiting component 22 is used to limit the position of the first attachment assembly 1 relative to the attachment body 21 to prevent the first attachment assembly 1 from detaching from the attachment body 21.

[0074] This configuration improves the reliability of the connection between the first coupling component 1 and the coupling body 21, thereby preventing the accidental detachment of the first coupling component 1 and the coupling body 21 to a certain extent, and ensuring the reliability of the connection between the tractor 20 and the trailer 30.

[0075] Specifically, when the second mounting component 2 includes a mounting body 21 and a limiting component 22, the mounting body 21 has the aforementioned mounting segment 211 and body segment 212.

[0076] For example, when the first mounting component 1 includes a mounting piece 11, the second mounting component 2 includes a mounting segment 211, and the mounting segment 211 has a mounting cavity 213, the setting of the limiting component 22 can ensure that the mounting piece 11 is reliably mounted in the mounting cavity 213.

[0077] In some embodiments, refer to Figure 3 and Figure 4 As shown, the limiting component 22 includes a backstop rotation member 221. The backstop rotation member 221 is rotatably connected to the hook-on body 21, and the backstop rotation member 221 can limit the position of the first hook-on component 1 relative to the hook-on body 21.

[0078] By rotating the anti-reverse rotating component 221 relative to the coupling body 21, the position of the first coupling component 1 relative to the coupling body 21 is limited, thereby ensuring reliable coupling between the tractor 20 and the trailer 30 to a certain extent and ensuring stable traction of the trailer 30 by the tractor 20.

[0079] Reference Figure 3and Figure 4 For example, there can be two anti-reverse rotating parts 221, with the two anti-reverse rotating parts 221 respectively located on both sides of the hanging body 21.

[0080] In the specific implementation, continue to refer to Figure 3 and Figure 4 As shown, the coupling cavity 213 may include a first cavity segment 215 and a second cavity segment 216 that are connected to each other. Along the direction of movement of the tractor 20 toward the trailer 30, the first cavity segment 215 is located between the main body segment 212 and the second cavity segment 216. The coupling member 11 can correspond to the second cavity segment 216 when the first detection member 3 detects the first cavity segment 215. The anti-rotation member 221 can confine the coupling member 11 within the first cavity segment 215.

[0081] This allows the hook-up piece 11 to move into the second cavity 216 under the drive of the drive piece 12, and then, through the rotation of the anti-reverse rotating piece 221 relative to the hook-up body 21, the hook-up piece 11 is confined within the first cavity 215, thereby ensuring reliable hook-up between the tractor 20 and the trailer 30 to a certain extent.

[0082] For example, when the hook-up 11 extends into the second cavity 216, the tractor 20 can be moved away from the trailer 30 so that the anti-reverse rotating member 221 can rotate under the drive of the hook-up 11 so that the hook-up 11 can enter the first cavity 215.

[0083] For example, the inner wall size of the first cavity segment 215 can be adapted to the outer contour size of the hanger 11 to ensure the hanging effect between the hanger 11 and the first cavity segment 215. Alternatively, the inner wall size of the second cavity segment 216 can be larger than the outer contour size of the hanger 11, thereby improving the efficiency of the hanger 11 being pre-extended into the second cavity segment 216.

[0084] In some embodiments, refer to Figure 4 As shown, the limiting component 22 also includes a limiting member 222. The limiting member 222 can abut against one side of the anti-rotation member 221 to restrict the rotation of the anti-rotation member 221 and cause the first hooking component 1 to disengage from the hooking body 21.

[0085] In this way, the limiting member 222 limits the anti-reverse rotation member 221, thereby preventing the anti-reverse rotation member 221 from rotating to the position where the first coupling assembly 1 and the coupling body 21 are disengaged, which would cause the first coupling assembly 1 and the coupling body 21 to disengage. This is beneficial to further ensure the coupling effect of the tractor 20 and the trailer 30.

[0086] Among them, the anti-reverse rotating component 221 can be a rotating block, rotating rib, etc.

[0087] The limiting component 222 can be a limiting block, a limiting protrusion, etc.

[0088] Specifically, when the hanger 11 is confined within the first cavity 215 by the anti-reverse rotation member 221, the setting of the limiting member 222 can prevent the anti-reverse rotation member 221 from accidentally rotating in a direction away from the main body section 212, which would cause the anti-reverse rotation member 221 to fail to confine the hanger 11 within the first cavity 215, thereby preventing the hanger 11 from accidentally moving out of the first cavity 215 to a certain extent.

[0089] In some embodiments, refer to Figure 4 As shown, the anti-reverse rotation member 221 has an arc-shaped guide surface 220 to guide the first hook assembly 1 when it is hooked to the hook body 21.

[0090] This configuration allows the first coupling component 1 to be guided by the arc-shaped guide surface 220, improving the ease of rotation of the anti-reverse rotating component 221 and facilitating the coupling of the first coupling component 1 and the coupling body 21. The coupling of the two is convenient and efficient, further improving the coupling efficiency of the tractor 20 and the trailer 30, making it more convenient to use.

[0091] Specifically, when the anti-reverse rotating member 221 rotates toward the main body section 212 under the drive of the hook member 11, so that the hook member 11 enters the first cavity section 215 from the second cavity section 216, the arc-shaped guide surface 220 can guide the hook member 11 to improve the ease of rotation of the anti-reverse rotating member 221.

[0092] In some embodiments, refer to Figure 4 As shown, the limiting component 22 also includes an elastic element 223. One end of the elastic element 223 is connected to the hanging body 21, and the other end of the elastic element 223 is connected to the anti-reverse rotation component 221.

[0093] Thus, due to the setting of the elastic element 223, during the process of the anti-reverse rotation element 221 rotating to realize the first hook assembly 1 and the hook body 21 hooking (for example, the hook 11 entering the first cavity 215), the anti-reverse rotation element 221 can be reset under the rebound force of the elastic element 223, thereby realizing the hooking of the first hook assembly 1 and the hook body 21. For example, at this time, the anti-reverse rotation element 221 can limit the hook 11 within the first cavity 215, which is convenient and flexible to use.

[0094] For example, the elastic element 223 can be a spring, an elastic rope, etc. Among them, the spring can be a tension spring, a compression spring, etc.

[0095] When there are two anti-reverse rotation components 221, there are also two elastic components 223 and two limiting components 222, which are set one-to-one with the anti-reverse rotation components 221.

[0096] This embodiment also provides a handling device, including a tractor 20, a trailer 30, and a coupling device 10.

[0097] The structure and implementation principle of the mounting device 10 are the same as those of the mounting device 10 provided in the above embodiments, and it can bring the same or similar technical effects.
