Description

Technical Field

[0001] The invention relates to the technical field of transport vehicle assembly, and in particular to an automatic unhooking hook tool and a transport vehicle. Background Art

[0002] In the process of promoting automated production lines, transport vehicles such as traction AGV carts are used to transfer materials between different processes. In order to facilitate material transfer, the materials are usually placed in a material tooling vehicle, and then the material tooling vehicle is assembled together with the transport vehicle. The material tooling vehicle and the materials inside it are transferred by the transport vehicle. The existing technology uses the material tooling vehicle as a whole for transfer, which can realize batch transfer and transmission of materials and improve the efficiency of material transfer and transmission.

[0003] In order to realize the rapid disassembly and assembly between the transport vehicle and the material handling vehicle, the prior art generally provides an openable and closable hook assembly at the end of the transport vehicle, and a traction piece at the end of the material handling vehicle. When the transport vehicle and the material handling vehicle need to be assembled together, the hook assembly is locked to the traction piece by manual traction and assembly to realize the assembly of the material handling vehicle and the transport vehicle. When the transport vehicle and the material handling vehicle need to be separated, the hook assembly is opened by manual traction and disassembly to separate the traction piece from the hook assembly, thereby realizing the separation of the material handling vehicle and the transport vehicle.

[0004] During the assembly and separation process of the above-mentioned traction parts and hook components, the hook components need to be manually connected and separated, and during manual operation, the transport vehicle and the material handling vehicle need to be in a stationary state. The transport vehicle is started and operated after assembly or separation, which reduces the working efficiency of the transport vehicle and cannot realize automated production and transportation without manual labor. Summary of the invention

[0005] In order to overcome the problems existing in the related technology, one of the purposes of the present invention is to provide an automatic unhooking hook tooling, which drives the first hook and the second hook to achieve plug-in and separation through an unhooking driving member, and can realize the automatic assembly and separation of the hook assembly and the traction member, thereby improving the assembly efficiency and further improving the efficiency of material transportation.

[0006] An automatic unhooking hook tool comprises a hook assembly, a bracket assembly and an unhooking driving member;

[0007] The hook assembly comprises a first hook and a second hook which are arranged opposite to each other, the first hook being fixed in the transport vehicle, the first end of the first hook being adaptable and pluggable with the first end of the second hook, the second end of the second hook being provided with a first hinged portion and a second hinged portion which are arranged in parallel, the first hinged portion being hinged to the second end of the first hook, and the second hinged portion being hinged to the detaching driving member through a bracket assembly;

[0008] The detaching driving member drives the second hook to rotate relative to the second end of the first hook through the bracket assembly, so that the first end of the first hook is plugged into or separated from the first end of the second hook.

[0009] When the detachment driving member is running, the second hook can be driven to rotate relative to the first hook through the bracket assembly, so that the second hook and the first end of the first hook are opened or closed. When the hook assembly is opened, the traction member can be moved into or out of the hook assembly. When the hook assembly is closed, the traction member can be fixed. In this way, the hook assembly and the traction member can be automatically assembled and separated, thereby realizing the automation process in the transportation process and improving the material transfer efficiency.

[0010] In a preferred technical solution of the present invention, the bracket assembly includes a first connecting rod, a second connecting rod and a third connecting rod, one end of the first connecting rod is hinged to the second hinged portion, and one end of the second connecting rod is fixedly connected to the first hook;

[0011] The other ends of the first connecting rod and the second connecting rod are respectively hinged to the two ends of the third connecting rod, and the output end of the detachment drive component is hinged to the connecting rod hinge point, and the connecting rod hinge point is the hinge point of the first connecting rod and the third connecting rod.

[0012] The bracket assembly in the present application includes three connecting rods hinged together. When the detaching driving member is extended or retracted, the first connecting rod, the second connecting rod and the third connecting rod cooperate with each other, and the hinge points between them interact with each other, driving the second hook to rotate around the first hinge. The bracket assembly provided in the present application has a simple structure and is easy to control. It can rotate and deform together with the detaching driving member, thereby improving the control accuracy and efficiency of the opening and closing of the hook assembly.

[0013] In a preferred technical solution of the present invention, the output end of the detachable driving member is connected to the hinge of the first connecting rod and the third connecting rod through a fourth connecting rod, and the two ends of the fourth connecting rod are respectively hinged to the output end of the detachable driving member and the connecting rod hinge point.

[0014] The addition of the fourth connecting rod in this application can ensure the rotation between the output end of the detaching driving member and the third connecting rod. Since the two ends of the fourth connecting rod are respectively hinged with the output end of the detaching driving member and the connecting rod hinge point, the telescopic and retracting directions of the detaching driving member can be set arbitrarily according to the position and orientation of the driving box, and then the telescopic movement of the detaching driving member is transmitted to the third connecting rod and the first connecting rod through the fourth connecting rod, thereby realizing the driving of the first connecting rod and the first hook. This setting can save the space and structure of the bracket assembly, thereby simplifying the layout of the automatic detaching hook tooling.

[0015] In a preferred technical solution of the present invention, an indicator rod is provided on the side of the third connecting rod close to the hook assembly, and a detector is provided in the second connecting rod; when the detaching driving member drives the second hook to be plugged into the first hook through the connecting rod assembly, the indicator rod abuts against the detector.

[0016] In the present application, the indicator rod can be used as a part of the third connecting rod. The indicator rod is set on the outside of the third connecting rod of the L-shaped bending structure. When the hook assembly is open, the indicator rod is located between the first connecting rod and the second connecting rod, and does not abut the second connecting rod. When the hook assembly is closed, the indicator rod abuts against the top of the second connecting rod, and a detector is set at the abutting position in the second connecting rod. When the detector detects that the indicator rod abuts, it indicates that the hook assembly is in a closed state. When the detector does not detect the indicator rod, it indicates that the hook assembly is in an open state, that is, the first hook and the second hook are in a separated state. The present application can realize accurate detection of the state of the hook assembly through the relative position relationship between the detector and the indicator rod, thereby improving the control accuracy of the hook assembly.

[0017] In a preferred technical solution of the present invention, the third connecting rod is an L-shaped bending structure, and the bending position coincides with the connecting rod hinge point, and the two ends of the third connecting rod are respectively hinged to the second connecting rod and the fourth connecting rod.

[0018] The bending angle of the third connecting rod can be slightly greater than 90°, and the bending position is the connecting rod hinge point, and the connecting rod hinge point is hinged to the first connecting rod, and the two ends of the third connecting rod are respectively hinged to the ends of the extended second connecting rod and the ends of the fourth connecting rod. The third connecting rod is connected to the first connecting rod, the second connecting rod and the fourth connecting rod at the same time, and is the driving transfer part of the connecting rod assembly, and cooperates with the first connecting rod and the second connecting rod to realize the precise control of the rotation position of the second hook.

[0019] In a preferred technical solution of the present invention, the fourth connecting rod is a Y-shaped structure, the bottom of the fourth connecting rod is hinged to the output end of the detachable driving member, and the top fork of the fourth connecting rod is hinged to both sides of the end of the third connecting rod.

[0020] The bottom of the fourth link refers to the side without bifurcation in the Y-shaped structure, which is hinged to the output end of the detachable drive member. The top of the fourth link refers to the bifurcation position in the Y-shaped structure, and the two ends after bifurcation are respectively hinged to the two sides of the end of the third link, so that the fourth link can evenly drive the third link to rotate from both sides, thereby achieving stable rotation between the fourth link and the third link.

[0021] The second object of the present application is to provide a transport vehicle, comprising an automatic uncoupling hook tool as described above, wherein the automatic uncoupling hook tool is fixed to the end of the transport vehicle.

[0022] In a preferred technical solution of the present invention, the side of the first hook away from the second hook is fixed to the side of the transport vehicle through a fixing assembly; and a plurality of parallel springs are arranged between the fixing assembly and the transport vehicle.

[0023] The presence of the spring can provide a buffer between the hook assembly and the transport vehicle, ensuring that the transport vehicle can stably drive the hook assembly and the traction parts and material tooling vehicle assembled with the hook assembly to move stably.

[0024] In a preferred technical solution of the present invention, the fixing assembly includes a connecting plate, a driving box and a fixing plate, the driving box is located between the connecting plate and the fixing plate, the side of the fixing plate away from the driving box is fixedly connected to the side of the transport vehicle, and the side of the connecting plate away from the driving box is fixedly connected to the first hook; a first spring is arranged between the connecting plate and the driving box, and a second spring is arranged between the fixing plate and the driving box.

[0025] The first spring is arranged between the connecting plate and the driving box to ensure the stability between the hook assembly and the driving box, and the second spring is arranged between the fixing plate and the driving box to ensure the stability between the driving box and the transport vehicle. Finally, the hook assembly, the connecting plate, the driving box and the fixing plate form a complete automatic unhooking hook tooling, which is fixed to the end of the transport vehicle, for example, at the front end of the transport vehicle, through the fixing plate as a whole, and the first spring and the second spring can ensure the stable connection between the hook assembly and the transport vehicle, and even in the event of violent vibration, the first spring and the second spring can also achieve buffering between the transport vehicle and the hook assembly to avoid damage to the hook assembly.

[0026] In a preferred technical solution of the present invention, there are two second springs, which are respectively located at the top and bottom of the fixed plate, a rotating shaft is arranged between the two second springs, and a rotating driving member is also arranged in the driving box, the output end of the rotating driving member is connected to the top or bottom of the side of the driving box close to the fixed plate, and the rotating driving member can drive the driving box, the connecting plate and the hook assembly to be lifted and lowered in the vertical direction along the rotating shaft.

[0027] In a preferred technical solution of the present invention, the side of the transport vehicle includes a charging plate, and the charging plate is located above or below the hook assembly.

[0028] The rotating drive member is fixed in the transport vehicle, and the output end of the rotating drive member is connected to the bottom of the drive box near the fixed plate. The bottom here refers to the side of the drive box away from the hook assembly, that is, the hook assembly is defined as being located at the top of the drive box. Since the fixed plate and the transport vehicle are fixedly connected, that is, the position of the fixed plate is relatively fixed, when the rotating drive member is extended, it will drive the bottom of the drive box to be compressed in the direction of the fixed plate. Since the fixed plate and the drive box are connected by a second spring, the bottom of the drive box compresses the spring at this time. Since the drive box, the connecting plate and the hook assembly are a unified whole, at this time, the drive box, the connecting plate and the hook assembly are synchronously tilted and rotated upward along the rotating shaft. The upward tilting rotation can make the automatic unhooking hook tooling tilt upward as a whole, thereby exposing the charging plate covered by the automatic unhooking hook tooling to realize charging of the transport vehicle. The present application can adjust the position of the automatic unhooking hook tooling by rotating the drive member. When the transport vehicle is operating normally, the automatic unhooking hook tooling is in a state such as Fig. 9 The state shown in the figure, at this time, the automatic unhooking hook tool covers the charging plate position; it can be assembled and separated from the traction part normally. When the transport vehicle needs to be charged, the automatic unhooking hook tool is in the state shown in the figure. Figure 8 In the state shown, the vehicle can be tilted upward under the driving force of the rotating drive member, so that the charging plate is exposed, thereby realizing charging of the transport vehicle.

[0029] The transport vehicle of the present application is provided with a hook assembly at the end, and the material tooling vehicle is provided with a traction piece at the end. Through the automatic assembly and separation between the hook assembly and the traction piece, automated material transportation can be realized without manual connection and separation of the hook assembly, thereby promoting the automation process of material transportation and improving the efficiency of material transportation.

[0030] The beneficial effects of the present invention are:

The second end of the second hook is provided with a first hinged portion and a second hinged portion in parallel, the first hinged portion is hinged with the second end of the first hook, and the second hinged portion is hinged with the unhooking drive member through the bracket assembly; that is, the second end of the second hook is hinged with the unhooking drive member and the first hook at the same time, ensuring that the unhooking drive member drives the second hook to rotate relative to the second end of the first hook through the bracket assembly, so that the first end of the first hook and the first end of the second hook are plugged or separated. When the detachment driving member is running, the second hook can be driven to rotate relative to the first hook through the bracket assembly, so that the second hook and the first end of the first hook are opened or closed. When the hook assembly is opened, the traction member can be moved into or out of the hook assembly. When the hook assembly is closed, the traction member can be fixed. In this way, the hook assembly and the traction member can be automatically assembled and separated, thereby realizing the automation process in the transportation process and improving the material transfer efficiency.

[0047] Example 1

[0048] like Figure 1-Figure 6 As shown, an automatic unhooking hook tool includes a hook assembly, a bracket assembly and an unhooking drive member 13;

[0049] The hook assembly includes a first hook 11 and a second hook 12 that are arranged opposite to each other. The first hook 11 is fixed in the transport vehicle 25. The first end of the first hook 11 and the first end of the second hook 12 can be adapted and plugged. The second end of the second hook 12 is provided with a first hinged portion and a second hinged portion that are arranged in parallel. The first hinged portion is hinged to the second end of the first hook 11, and the second hinged portion is hinged to the detaching driving member 13 through a bracket assembly.

[0050] The detaching driving member 13 drives the second hook 12 to rotate relative to the second end of the first hook 11 through the bracket assembly, so that the first end of the first hook 11 and the first end of the second hook 12 are plugged in or separated.

[0051] In the present application, the first end of the first hook 11 and the first end of the second hook 12 are respectively provided with corresponding plug-in grooves and plug-in protrusions, which can realize the closing and opening of the first hook 11 and the second hook 12, and then realize the assembly and separation between the hook assembly and the external traction member 30. In order to ensure that the first hook 11 and the second hook 12 can be locked when closed, the first end of the first hook 11 and the first end of the second hook 12 can be provided with an adapted plug-in groove and a plug-in protrusion, and when the plug-in protrusion is inserted into the plug-in groove, it can ensure that the first hook 11 and the second hook 12 are locked, and the phenomenon of falling off during the traction process can be avoided. The automatic unhooking hook tool in the present application can be installed at the end of any transport vehicle 25, such as an AGV trolley, etc., and can also be installed in other devices that need to be connected and separated with an external structure. When the first hook 11 and the second hook 12 are separated, the hook assembly is opened, and the traction member 30 or other components can be extended into the hook assembly. When the first hook 11 and the second hook 12 are plugged, the hook assembly is closed, and the traction member 30 or other components can be fixed at this time.

[0052] In the present application, the second end of the second hook 12 is hinged to the detaching drive member 13 and the first hook 11 at the same time, ensuring that the detaching drive member 13 drives the second hook 12 to rotate relative to the second end of the first hook 11 through the bracket assembly, so that the first end of the first hook 11 and the first end of the second hook 12 are plugged in or separated. In other words, the second end of the second hook 12 can be rotated under the drive of the detaching drive member 13, and the direction of rotation is to rotate along the hinge point of the second end of the first hook 11 and the second hook 12. It can be understood that: the second hinged part and the first hinged part of the second hook 12 are arranged in parallel, and at the same time, the detaching drive member 13 drives the second hook 12 to rotate through the second hinged part, and the direction of rotation is to rotate relative to the first hinged part, thereby realizing the plugging and separation of the first hook 11 and the second hook 12.

[0053] The working principle of the present application is as follows: when the detachment drive member 13 is running, the second hook 12 can be driven to rotate relative to the first hook 11 through the bracket assembly, so that the second hook 12 and the first end of the first hook 11 are opened or closed, and when the hook assembly is opened, the traction member 30 can be moved in or out of the hook assembly, and when the hook assembly is closed, the traction member 30 can be fixed, so that the hook assembly and the traction member 30 can be automatically assembled and separated, thereby realizing the automation process in the transportation process and improving the material transfer efficiency.

[0054] Example 2

[0055] like Figure 1-Figure 6 As shown, the present application provides an automatic unhooking hook tool, including a hook assembly, a bracket assembly and an unhooking drive member 13;

[0056] The hook assembly includes a first hook 11 and a second hook 12 that are arranged opposite to each other. The first hook 11 is fixed in the transport vehicle 25. The first end of the first hook 11 and the first end of the second hook 12 can be adapted and plugged. The second end of the second hook 12 is provided with a first hinged portion and a second hinged portion that are arranged in parallel. The first hinged portion is hinged to the second end of the first hook 11, and the second hinged portion is hinged to the detaching driving member 13 through a bracket assembly.

[0057] The detaching driving member 13 drives the second hook 12 to rotate relative to the second end of the first hook 11 through the bracket assembly, so that the first end of the first hook 11 and the first end of the second hook 12 are plugged in or separated.

[0058] Furthermore, the bracket assembly includes a first connecting rod 14, a second connecting rod 15 and a third connecting rod 16, one end of the first connecting rod 14 is hinged to the second hinge part, and one end of the second connecting rod 15 is fixedly connected to the first hook 11; the other ends of the first connecting rod 14 and the second connecting rod 15 are respectively hinged to the two ends of the third connecting rod 16, and the output end of the detachment drive 13 is hinged to the connecting rod hinge point 19, and the connecting rod hinge point 19 is the hinge point of the first connecting rod 14 and the third connecting rod 16.

[0059] The bracket assembly in the present application includes three connecting rods hinged together. When the hook-off drive member 13 is extended or retracted, the first connecting rod 14, the second connecting rod 15 and the third connecting rod 16 cooperate with each other, and the hinge points between them interact with each other to drive the second hook 12 to rotate around the first hinge. The bracket assembly provided in the present application has a simple structure and is easy to control. It can rotate and deform together with the hook-off drive member 13, thereby improving the control accuracy and efficiency of the opening and closing of the hook assembly.

[0060] Specifically, the output end of the detachable driving member 13 is connected to the hinge of the first connecting rod 14 and the third connecting rod 16 through the fourth connecting rod 17, and the two ends of the fourth connecting rod 17 are respectively hinged to the output end of the detachable driving member 13 and the connecting rod hinge point 19.

[0061] The fourth connecting rod 17 added in this application can ensure the rotation between the output end of the detaching driving member 13 and the third connecting rod 16. Since the two ends of the fourth connecting rod 17 are respectively hinged with the output end of the detaching driving member 13 and the connecting rod hinge point 19, the telescopic and retracting directions of the detaching driving member 13 can be set arbitrarily according to the position and orientation of the driving box 23, and then the telescopic movement of the detaching driving member 13 is transmitted to the third connecting rod 16 and the first connecting rod 14 through the fourth connecting rod 17, thereby realizing the driving of the first connecting rod 14 and the first hook 11. This arrangement can save the space and structure of the bracket assembly, thereby simplifying the layout of the automatic detaching hook tooling.

[0062] like Figure 1-Figure 2 As shown, the first connecting rod 14 is an H-shaped structure, which is convenient for designing a symmetrical structure, that is, one end of the first connecting rod 14 is respectively hinged to the two ends of the second hinged portion, so that the force of the first connecting rod 14 on the second hook 12 is evenly driven from both sides, thereby achieving stable rotation between the first connecting rod 14 and the second hook 12. The other end of the first connecting rod 14 is respectively hinged to the two ends of the connecting rod hinge point 19 in the third connecting rod 16, which can also ensure stable rotation between the first connecting rod 14 and the third connecting rod 16.

[0063] like Figure 1-Figure 2As shown, the second connecting rod 15 is an L-shaped structure, one end of the second connecting rod 15 is fixed to the outer wall of the first hook 11, and the other end of the second connecting rod 15 extends toward the direction close to the first connecting rod 14 and is hinged to the end of the third connecting rod 16. Figure 2 As shown, two hinged parts can be arranged in parallel at the other end of the second connecting rod 15 for connecting the two ends of the third connecting rod 16 , so as to ensure the stable rotation between the second connecting rod 15 and the third connecting rod 16 .

[0064] like Figure 5 As shown, the third connecting rod 16 is an L-shaped bending structure, and the bending position coincides with the connecting rod hinge point 19 , and the two ends of the third connecting rod 16 are hinged to the second connecting rod 15 and the fourth connecting rod 17 respectively.

[0065] Specifically, the bending angle of the third connecting rod 16 can be slightly greater than 90°, and the bending position is the connecting rod hinge point 19, and the connecting rod hinge point 19 is hinged to the first connecting rod 14, and the two ends of the third connecting rod 16 are respectively hinged to the ends of the extended second connecting rod 15 and the ends of the fourth connecting rod 17. The third connecting rod 16 is connected to the first connecting rod 14, the second connecting rod 15 and the fourth connecting rod 17 at the same time, and is the driving transfer part of the connecting rod assembly, and cooperates with the first connecting rod 14 and the second connecting rod 15 to achieve accurate control of the rotation position of the second hook 12.

[0066] like Figure 6 As shown, the fourth connecting rod 17 is a Y-shaped structure, the bottom of the fourth connecting rod 17 is hinged to the output end of the detaching driving member 13, and the top fork of the fourth connecting rod 17 is hinged to both sides of the end of the third connecting rod 16 respectively.

[0067] The bottom of the fourth connecting rod 17 refers to the side of the Y-shaped structure without bifurcation, which is hinged to the output end of the detaching drive member 13. The top of the fourth connecting rod 17 refers to the bifurcation position in the Y-shaped structure, such as Figure 6 As shown, the two ends after bifurcation are respectively hinged to the two sides of the end of the third connecting rod 16, so that the fourth connecting rod 17 can evenly drive the third connecting rod 16 to rotate from both sides, thereby achieving stable rotation between the fourth connecting rod 17 and the third connecting rod 16.

[0068] like Figure 3-Figure 5 As shown, an indicator rod 18 is provided on one side of the third connecting rod 16 close to the hook assembly, and a detector is provided in the second connecting rod 15; when the detaching driving member 13 drives the second hook 12 to be plugged into the first hook 11 through the connecting rod assembly, the indicator rod 18 abuts against the detector.

[0069] In the present application, the indicator rod 18 can be used as a part of the third connecting rod 16, such as Figure 5As shown, an indicator rod 18 is provided on the outer side of the third connecting rod 16 of the L-shaped bending structure, as shown in FIG. Figure 3 and Figure 4 As shown, when the hook assembly is open, the indicator rod 18 is located between the first connecting rod 14 and the second connecting rod 15, and does not abut against the second connecting rod 15. When the hook assembly is closed, the indicator rod 18 abuts against the top of the second connecting rod 15, and a detector is provided at the abutting position in the second connecting rod 15. When the detector detects that the indicator rod 18 abuts, it indicates that the hook assembly is in a closed state. When the detector does not detect the indicator rod 18, it indicates that the hook assembly is in an open state, that is, the first hook 11 and the second hook 12 are in a separated state. The present application can realize accurate detection of the state of the hook assembly through the relative position relationship between the detector and the indicator rod 18, thereby improving the control accuracy of the hook assembly.

[0070] like Figure 1-Figure 3 As shown, in this embodiment, the disengagement drive member 13 can be specifically in the form of a cylinder or the like. When the disengagement drive member 13 is extended, the output end of the disengagement drive member 13 drives the fourth connecting rod 17 to rise, and there is a certain angle between the fourth connecting rod 17 and the third connecting rod 16. Under the driving action of the fourth connecting rod 17, the third connecting rod 16 presses the connecting rod hinge point 19 toward the direction close to the hook assembly, so that a straight line is formed between the left bending part of the first connecting rod 14 and the third connecting rod 16, and the first connecting rod 14 then drives the second hook 12 to be inserted into the first hook 11 through the second hinge part, so as to realize the closure of the first hook 11 and the second hook 12.

[0071] When the detaching drive member 13 is retracted, Figure 4 As shown, the output end of the unhooking driving member 13 drives the fourth connecting rod 17 to descend, and there is a certain angle between the fourth connecting rod 17 and the third connecting rod 16. Under the pushing action of the fourth connecting rod 17, the third connecting rod 16 pulls the connecting rod hinge point 19 away from the hook assembly, so that the left side of the first connecting rod 14 and the third connecting rod 16 forms a Figure 4 As shown in the nearly vertical angle, the first connecting rod 14 exerts a pulling force on the second hook 12 in the direction close to the detaching drive member 13, so that the first end of the second hook 12 is disengaged from the first end of the first hook 11, thereby realizing the opening of the first hook 11 and the second hook 12.

[0072] When the detachment drive member 13 is running, the second hook 12 can be driven to rotate relative to the first hook 11 through the bracket assembly, so that the second hook 12 and the first end of the first hook 11 are opened or closed. When the hook assembly is opened, the traction member 30 can be moved into or out of the hook assembly. When the hook assembly is closed, the traction member 30 can be fixed. In this way, the hook assembly and the traction member 30 can be automatically assembled and separated, thereby realizing the automation process in the transportation process and improving the material transfer efficiency.

[0073] Example 3

[0074] like Figure 7-Figure 9 As shown, a transport vehicle provided by the present application includes an automatic unhooking hook tool as described in Example 2, and the automatic unhooking hook tool is fixed to the end of the transport vehicle 25. The transport vehicle 25 can be specifically an AGV vehicle.

[0075] In the present application, casters are provided at the bottom of the transport vehicle 25, and it can move along a specific track under the action of self-drive. Furthermore, in the present application, the transport vehicle 25 is used to carry out material traction and transfer between different processes in the production line structure. Specifically, a material work vehicle can be set at the inlet and outlet of each process, and the material work vehicle is filled with materials. A traction member 30 is provided at the end of the material work vehicle. When the hook assembly is opened, the traction member 30 can be moved in or out of the hook assembly. When the hook assembly is closed and the traction member 30 is locked in the hook assembly, the assembly of the transport vehicle 25 and the material work vehicle can be realized. At this time, the transport vehicle 25 can drive the material work vehicle to move to realize the transfer of materials.

[0076] The automatic opening and closing structure and principle of the hook assembly in this embodiment are as shown in Example 2 and will not be described in detail here.

[0077] In this embodiment, the side of the first hook 11 away from the second hook 12 is fixed to the side of the transport vehicle 25 through a fixing assembly; a plurality of parallel springs are arranged between the fixing assembly and the transport vehicle 25.

[0078] The presence of the spring can provide a buffer between the hook assembly and the transport vehicle 25, ensuring that the transport vehicle 25 can stably drive the hook assembly and the traction member 30 and the material handling vehicle assembled with the hook assembly to move stably.

[0079] Further, such as Figure 8 and Fig. 9The figure is a schematic diagram of the inverted installation of the hook assembly. The fixing assembly includes a connecting plate 22, a drive box 23 and a fixing plate 24, the drive box 23 is located between the connecting plate 22 and the fixing plate 24, the side of the fixing plate 24 away from the drive box 23 is fixedly connected to the side of the transport vehicle 25, and the side of the connecting plate 22 away from the drive box 23 is fixedly connected to the first hook 11; a first spring 20 is arranged between the connecting plate 22 and the drive box 23, and a second spring 21 is arranged between the fixing plate 24 and the drive box 23.

[0080] In the present application, the first hook 11 is fixed in the connecting plate 22, the driving box 23 can be a rectangular box structure, located between the connecting plate 22 and the fixing plate 24, and the opposite sides of the driving box 23 can be directly used as mounting plates. The first spring 20 is arranged between the connecting plate 22 and the driving box 23 to ensure the stability between the hook assembly and the driving box 23, and the second spring 21 is arranged between the fixing plate 24 and the driving box 23 to ensure the stability between the driving box 23 and the transport vehicle 25. Finally, the hook assembly, the connecting plate 22, the driving box 23 and the fixing plate 24 form a complete automatic unhooking hook tooling, which is fixed to the end of the transport vehicle 25, for example, fixed to the front end of the transport vehicle 25, by the fixing plate 24, and the stable connection between the hook assembly and the transport vehicle 25 can be ensured by the first spring 20 and the second spring 21. Even when violent vibration occurs, the first spring 20 and the second spring 21 can also achieve buffering between the transport vehicle 25 and the hook assembly to avoid damage to the hook assembly.

[0081] Furthermore, there are two second springs 21, which are respectively located at the top and bottom of the fixed plate 24, and a rotating shaft 27 is provided between the two second springs 21. A rotating driving member 28 is also provided in the driving box 23, and the output end of the rotating driving member 28 is connected to the top or bottom of the side of the driving box 23 close to the fixed plate 24, and the rotating driving member 28 can drive the driving box 23, the connecting plate 22 and the hook assembly to rise and fall in the vertical direction along the rotating shaft 27. The side of the transport vehicle 25 includes a charging plate 26, and the charging plate 26 is located above or below the hook assembly.

[0082] In the present application, an arc-shaped guide member may be provided between the driving box and the fixed plate, and the rotating shaft is provided in the arc-shaped guide member. Figure 8 and Fig. 9 As shown, ensure that the automatic unhooking hook tooling is stably tilted up along the rotating axis.

[0083] like Figure 8As shown, the rotating driving member 28 is fixed in the transport vehicle 25, and the output end of the rotating driving member 28 is connected to the bottom of the driving box 23 near the fixed plate 24. The bottom here refers to the side of the driving box 23 away from the hook assembly, that is, the hook assembly is defined to be located at the top of the driving box 23. Since the fixed plate 24 and the transport vehicle 25 are fixedly connected, that is, the position of the fixed plate 24 is relatively fixed, when the rotating driving member 28 is extended, it will drive the bottom of the driving box 23 to be compressed in the direction of the fixed plate 24. Since the fixed plate 24 and the driving box 23 are connected by the second spring 21, the bottom of the driving box 23 compresses the spring at this time. Since the driving box 23, the connecting plate 22 and the hook assembly are a unified whole, at this time, the driving box 23, the connecting plate 22 and the hook assembly are synchronously tilted and rotated upward along the rotating shaft 27. The tilted rotation upward can make the automatic unhooking hook tooling tilt upward as a whole, thereby exposing the charging plate 26 covered by the automatic unhooking hook tooling, so as to realize the charging of the transport vehicle 25. The present application can adjust the position of the automatic unhooking hook tooling by rotating the driving member 28 .

[0084] When the transport vehicle 25 operates normally, the automatic unhooking hook tool is in the state of Fig. 9 In the state shown, the automatic unhooking hook tool covers the charging plate 26 and can be assembled and separated from the traction member 30 normally. When the transport vehicle 25 needs to be charged, the automatic unhooking hook tool is in the state shown. Figure 8 In the state shown, the vehicle 20 can be tilted upward under the driving force of the rotating drive member 28 , so that the charging plate 26 is exposed, thereby realizing charging of the transport vehicle 25 .

[0085] A hook assembly is provided at the end of the transport vehicle 25, and a traction member 30 is provided at the end of the material handling vehicle. Through the automatic assembly and separation between the hook assembly and the traction member 30, automated material transportation can be achieved without manual insertion and separation of the hook assembly, thereby promoting the automation process of material transportation and improving the efficiency of material transportation.
