In the embodiment of the present application, all directional indications (such as up, down, left, right, front, back, top, bottom ...) are only constructed to explain the relative position relationship, motion situation, etc. between the components under a certain specific posture (as shown in the drawings), and if the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any deformation thereof are intended to cover non-exclusive inclusions. For example, the process, method, system, product or equipment comprising a series of steps or units are not limited to the steps or units listed, but optionally also include the steps or units not listed, or optionally also include other steps or units inherent to these processes, methods, products or equipment.

[0055] In addition, the reference to "embodiment" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiment may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0056] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0057] After briefly introducing the implementation principle of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the drawings in the embodiments of the present application.

[0058] As one aspect of the present application, the present application provides a container spreader rotating door plate blocking device, such as Figure 1As shown, the container spreader rotary door plate door blocking device comprises: a pull rod 22, a first drive mechanism, an inner door blocking mechanism and an outer door blocking mechanism. The container spreader rotary door plate door blocking device can be applied to a door plate that can be rotated to open and close.

[0059] The pull rod 22 is configured to be rotatable. Specifically, one end of the pull rod 22 can be hinged to form a rotation, and the other end of the pull rod 22 can be a free end. In actual use, one end of the pull rod 22 is rotatably connected to an external installation position, and the pull rod 22 can swing by rotating around the rotation axis.

[0060] The first driving mechanism is connected to the pull rod 22, and the first driving mechanism is configured to drive the pull rod 22 to rotate. Specifically, the first driving mechanism is used to drive the pull rod 22 to move, thereby realizing the swing of the pull rod 22 around the rotation axis.

[0061] The inner door stop mechanism is arranged on the pull rod 22, and the inner door stop mechanism is configured to selectively contact or disengage with the inner side of the door panel 5. When the inner door stop mechanism contacts the door panel 5, the inner door stop mechanism and the outer door stop mechanism are respectively located on opposite sides of the door panel 5, that is, the inner door stop mechanism and the outer door stop mechanism can jointly form a clamping effect on the door panel 5, so that the door panel 5 is more stable during the opening process. When the inner door stop mechanism and the door panel are disengaged from each other, the door panel 5 can be closed better.

[0062] Specifically, the inner door stop mechanism is connected to the pull rod 22, and can move along an arc track under the drive of the pull rod 22, and the inner door stop mechanism is attached to the inner side of the door panel 5 after the door panel 5 is opened. During the closing process of the door panel 5, when the distance between the door panel 5 and the container body reaches a threshold, the inner door stop mechanism is separated from the inner side of the door panel 5, thereby facilitating the smooth closing of the door panel 5. When the pull rod 22 swings, it can drive the inner door stop mechanism and the outer door stop mechanism connected to the pull rod 22 to swing, thereby driving the door panel 5 to open and close.

[0063] The outer door-blocking mechanism is rotatably connected to the inner door-blocking mechanism, so that the outer door-blocking mechanism can contact the outer side of the door panel 5 .

[0064] Specifically, the outer door-stop mechanism is rotatably connected to the inner door-stop mechanism, and the outer door-stop mechanism can rotate. The rotation axis of the outer door-stop mechanism is parallel to the rotation axis of the door panel 5. When the door panel 5 is opening, the angle of the outer side surface of the door panel 5 relative to the outer door-stop mechanism will keep changing. In order to ensure that the outer door-stop mechanism can fit well with the outer side surface of the door panel 5, the outer door-stop mechanism needs to rotate.

[0065] In a possible implementation of the present application, Figure 3 and Figure 4As shown, the inner door blocking mechanism includes: a mounting frame, a locking portion and a second driving mechanism.

[0066] The mounting frame is fixedly connected to the pull rod 22. The mounting frame is used to provide a mounting space for the locking part and the second driving mechanism. The locking part is rotatably connected to the mounting frame. The locking part can be rotatably connected to the mounting frame through a rotating shaft, and the locking part rotates clockwise or counterclockwise relative to the mounting frame, thereby being hooked on the inner side of the door panel or detached from the inner side of the door panel.

[0067] The second driving mechanism is connected to the locking part, and the second driving mechanism is configured to drive the locking part to rotate so as to contact or disengage with the inner side of the door panel 5. Specifically, the second driving mechanism is used to provide a driving force, and the driving force can drive the locking part to rotate around the rotation axis of the locking part itself. The locking part is brought into contact with or disengaged from the inner side of the door panel 5 by the rotation of the locking part.

[0068] In a possible implementation of the present application, Figure 3 and Figure 4 As shown, the second driving mechanism includes: a connecting seat 236 and an elastic member 231 .

[0069] The connecting seat 236 is arranged outside the locking part. Specifically, the connecting seat 236 is fixedly arranged outside the hook head 233, one telescopic end of the elastic member 231 is connected to the fixing seat, and the other telescopic end of the elastic member 231 is connected to a surface of the mounting frame opposite to the connecting seat 236.

[0070] The elastic member 231 is fixedly connected to the mounting frame and the connecting seat 236 respectively. The two ends of the elastic member that can be extended and retracted can be connected to the connecting seat 236 and the side of the mounting frame opposite to the connecting seat 236 respectively by welding or bonding. The elastic member 231 is configured to drive the locking part to rotate. The elastic member 231 drives the locking part to rotate around the rotating shaft by the force generated by its own deformation.

[0071] Thus, the lock hook can be pushed to rotate by the expansion and contraction of the elastic member 231. The elastic member 231 in this embodiment is a spring. Figure 3 As shown, when the spring is extended, the lock hook rotates clockwise, and the hook head 233 will hook on the inner side of the door panel 5, thereby limiting the inner side of the door panel 5. Figure 4 As shown, when the door panel 5 is in the process of closing, the outer side of the lock head will contact the external obstruction, and as the door panel 5 continues to approach the container body, the force of the outer side of the lock head being squeezed by the obstruction will gradually increase. When the squeezing force is greater than the elastic force of the elastic member 231, the lock hook will rotate counterclockwise, so that the hook head 233 will be separated from the inner side of the door panel 5, and unlocking will be achieved, so that the door panel 5 can be close to the container body to complete the closing action. The external obstruction can be a part of the structure of the container body or a part of the structure of the sling 4, such as the telescopic beam 41.

[0072] Optionally, the locking portion includes a locking hook.

[0073] The locking hook comprises a hook head 233, a connecting portion 234 and a mounting end 235. The mounting end 235 is rotatably connected to the mounting frame via a rotating shaft. The connecting portion 234 connects the hook head 233 and the mounting end 235. The hook head 233, the connecting portion 234 and the mounting end 235 are integrally formed.

[0074] Optionally, the inner side of the hook head 233 has a disengagement slope. By providing the disengagement slope, it is convenient for the lock hook to be hooked into the inner side of the door panel 5 or the lock hook to be smoothly disengaged from the inner side of the door panel 5.

[0075] In a possible implementation of the present application, Figure 3 and Figure 4 As shown, the connection seat 236 has a blind hole, and the mounting frame has a stepped through hole, which faces the blind hole. In this embodiment, the elastic member 231 is set as a spring, and the two ends of the spring are respectively set against the step surface of the stepped through hole and the inner bottom surface of the blind hole. In this way, the spring can be limited.

[0076] The second driving mechanism further includes a push rod 232 , one end of which is rotatably connected to the blind hole of the connecting seat 236 via a pin, and the other end of the push rod 232 passes through the stepped through hole.

[0077] The elastic member 231 is sleeved on the top rod 232, and the elastic member 231 abuts against the step of the step through hole. Therefore, during the rotation of the lock hook, the top rod 232 will shuttle in the step through hole, and the spring sleeved on the top rod 232 will be extended and retracted. The top rod 232 can provide a retracting guide for the spring, so that the spring is not easy to bend sideways during the retracting process, and can be smoothly extended and retracted along the axis of the spring, so as to stably provide the driving force required for the clockwise rotation of the lock hook.

[0078] In a possible implementation of the present application, Figure 5 As shown, the inner door blocking mechanism also includes: a position detection device 239 and a control device.

[0079] The position detection device 239 is fixedly arranged at the detection position of the pull rod 22, and the position detection device 239 is configured to obtain displacement information of the detection position along with the rotation of the pull rod 22. The position detection device 239 is a distance sensor, which can obtain the distance between the detection position and the surface where the container body and the inner side of the door panel 5 are in contact, and then obtain the displacement information of the pull rod 22, and then send the displacement information to the control device.

[0080] The control device is connected to the position detection device 239 and the second drive mechanism in communication, so that the control device controls the second drive mechanism to drive the rotation of the locking part according to the displacement information. The control device can make a judgment based on the received displacement information. When the displacement information reaches a preset threshold, the control device sends a control instruction, and the second drive mechanism performs a corresponding action through the control instruction. In this embodiment, specifically, when the door panel 5 is in the process of opening, after the displacement information reaches the threshold, the second drive mechanism is actuated to drive the lock hook to rotate clockwise until the lock head is hooked to the inner side of the door panel 5, and then the second drive mechanism stops to maintain the contact state between the lock head and the inner side of the door panel 5. When the door panel 5 is in the process of closing, after the displacement information reaches the threshold, the second drive mechanism is actuated to drive the lock hook to rotate counterclockwise until the lock head is detached from the door panel 5 and the lock hook returns to the preset position, and then the second drive mechanism stops to keep the lock hook in the preset position.

[0081] In a possible implementation of the present application, Figure 5 As shown, the second driving mechanism includes an opening and closing hydraulic cylinder 238 and a solenoid valve.

[0082] Among them, the opening and closing hydraulic cylinder 238, one end of the opening and closing hydraulic cylinder 238 is rotatably connected to the pull rod 22 through a hinged support, and the other end of the opening and closing hydraulic cylinder 238 is hinged to the outside of the hook lock. The opening and closing hydraulic cylinder 238 changes its length by extending and retracting the telescopic end, thereby driving the locking part connected to one end of the opening and closing hydraulic cylinder 238, that is, the lock hook, to rotate.

[0083] The solenoid valve is arranged on the liquid inlet pipeline of the opening and closing hydraulic cylinder 238, and the solenoid valve is communicatively connected with the control device.

[0084] The second driving mechanism is hinged to the connecting portion 234 of the lock hook, and can drive the lock hook to rotate when the opening and closing hydraulic cylinder 238 is extended and retracted.

[0085] Specifically, when the displacement signal reaches the threshold, the control device controls the corresponding solenoid valve to operate, thereby causing the telescopic end of the opening and closing hydraulic cylinder 238 to extend or retract, thereby driving the locking hook to rotate clockwise or counterclockwise.

[0086] In a possible implementation of the present application, Figure 3 and Figure 4 As shown, it is characterized in that the outer door blocking mechanism includes a blocking plate 241.

[0087] The baffle plate 241 is rotatably arranged on the inner door blocking mechanism through a pin shaft. Specifically, a rotating arm is provided on one side of the baffle plate 241, and a rotating seat is provided on the bottom plate 31. The rotating arm is rotatably connected to the rotating seat through a pin shaft. The baffle plate 241 is configured to contact the outer side of the door panel 5. When the lock hook rotates clockwise to be hooked to the inner side of the door panel 5, a receiving space for accommodating the door panel 5 is formed between the hook head 233 and the baffle plate 241. The door panel 5 is restricted to prevent the door panel 5 from shaking during the unloading operation of the container.

[0088] In a possible implementation of the present application, Figure 5 and Figure 6 As shown, the first driving mechanism includes a reducer 1 or a driving hydraulic cylinder 21 .

[0089] The reducer 1 has an output end, the pull rod 22 has a rotating shaft, and the rotating shaft of the pull rod 22 is connected to the output end of the reducer 1. The rotation of the output end of the reducer 1 drives the rotating shaft on the pull rod 22 to rotate, thereby realizing the rotation of the pull rod 22.

[0090] One end of the driving hydraulic cylinder 21 is rotatably connected to the pull rod 22. The driving hydraulic cylinder 21 and the outer door blocking mechanism are located on the same side of the inner door blocking mechanism. When the first driving mechanism includes the driving hydraulic cylinder 21, the pull rod 22 can be driven to swing around the rotation axis through the extension and contraction of the driving hydraulic cylinder 21.

[0091] Specifically, by arranging the driving hydraulic cylinder 21 and the outer door-blocking mechanism on the same side of the inner door-blocking mechanism, during the opening and closing of the door panel 5, the driving hydraulic cylinder 21 can achieve a larger swing angle of the pull rod 22 by extending and retracting a smaller length. At the same time, when arranged at this position, the driving hydraulic cylinder 21 can provide a smaller pulling force on the door panel 5 to offset the thrust generated on the door panel 5 when the materials inside the container dump outwards. Therefore, a hydraulic cylinder that generates a smaller pulling force can be selected as the driving hydraulic cylinder 21, thereby increasing the selection range of the driving hydraulic cylinder 21.

[0092] In a possible implementation of the present application, Figure 1 As shown, the mounting frame includes: a bottom plate 31 , two sets of first side plates 32 , a top plate 33 and a clamping plate 237 .

[0093] The bottom plate 31 is connected to the pull rod 22. The first side plates 32 are connected to the bottom plate 31 and the pull rod 22 respectively. The two sets of first side plates 32 are arranged opposite to each other, and an installation space is formed between the two sets of first side plates 32.

[0094] The top plate 33 is connected to the two sets of first side plates 32, and is arranged opposite to the bottom plate 31. The top plate 33 has a first through hole. The clamping plate 237 is connected to the top plate 33, and has a second through hole. The first through hole and the second through hole form a stepped through hole.

[0095] Specifically, the card plate 237 can be detachably mounted on the top plate 33, and the first through hole on the top plate 33 can be used as a window for later maintenance. When maintenance is required, the card plate 237 is removed and the structure in the installation space is inspected through the first through hole.

[0096] In a possible implementation of the present application, Figure 5 As shown, the mounting frame includes two sets of second side panels 34 .

[0097] The two sets of second side plates 34 are both connected to the pull rod 22, the two sets of second side plates 34 are arranged opposite to each other, and an installation space is formed between the two sets of second side plates 34. The hook lock is rotatably installed in the installation space, so that the hook lock is protected by the two sets of second side plates 34, which can reduce the probability of external force damaging the hook lock. The structural form of the mounting frame in this embodiment is more suitable for the scenario when the second driving mechanism in this application is an opening and closing hydraulic cylinder 238.

[0098] According to another aspect of the present application, Figure 7 As shown, the present application provides a container handling machine, comprising a telescopic beam 41 and a rotating door plate door blocking device for a container spreader as described in any one of the above items.

[0099] The pull rod 22 of the container spreader rotating door plate door stop device is rotatably connected to the telescopic beam 41 , and the first driving mechanism of the container spreader rotating door plate door stop device is rotatably connected to the telescopic beam.

[0100] The container handling machinery includes reach stackers, yard cranes, quay cranes, telescopic forklifts, stackers or Figure 7 The sling 4 shown in FIG.

[0101] Specifically, Figure 7 As shown, two sets of container spreader rotating door panel door-blocking devices are arranged on the telescopic crossbeam 41 of the spreader 4, and each set of container spreader rotating door panel door-blocking devices is used to control the opening and closing of a door panel 5 on the container.

[0102] The above are only preferred embodiments of the invention of this application and are not intended to limit the invention of this application. Any modifications, equivalent substitutions, etc. made within the spirit and principles of the invention of this application should be included in the protection scope of the invention of this application.
