Description
Technical Field
[0001] This utility model belongs to the technical field of unlocking devices, and in particular relates to a container unlocking device. Background Technology
[0002] A container twist lock is a device used to secure and lock containers. It is typically installed on vehicles, trailers, railways, or ships to ensure that the container does not shift or tilt during transportation. After the container is separated from the carrier, the twist lock at the bottom of the container needs to be disassembled and recycled. A twist lock usually consists of a shell and a rotating locking tongue, the end of which is locked to the bottom of the container. Due to the wide variety of regions that containers travel to, there are many specifications and models of twist locks. The existing unlocking method is usually manual unlocking, which is inefficient.
[0003] Therefore, how to avoid the low unlocking efficiency caused by the numerous specifications of twist locks is a technical problem that urgently needs to be solved in this field.
[0004] It should be noted that the information disclosed in this background section is only for understanding the background technology of the present application concept, and therefore, the above description is not considered to constitute prior art information. Utility Model Content

In short, the sensor 41 detects the shape and position of the twist lock and transmits it to the controller. The controller controls the gripping gripper 21 to clamp the shape of the twist lock and controls the unlocking gripper 31 to rotate the lock tongue of the twist lock. After the sensor 41 detects the shape of the twist lock, it determines the clamping position of the gripping gripper 21, thereby achieving automatic unlocking of the twist lock and improving unlocking efficiency.

The longitudinal sliding pair 24 is disposed on top of the lateral sliding block 23b, and the lateral sliding pairs 23 share the lateral guide rail 23a, and the lateral guide rail 23a is provided in pairs. In short, all lateral sliding pairs 23 share the lateral guide rail 23a, that is, all lateral sliding blocks 23b slide on the same lateral guide rail 23a, saving space in the housing 22.
[0046] In some embodiments, the lateral sliding pair 23 further includes a drive motor 23c and a drive rack 23d; the drive motor 23c is installed at the bottom of the lateral sliding block 23b, the drive rack 23d is installed inside the housing 22, and the output shaft of the drive motor 23c is connected to the drive rack 23d via gears; in short, the drive rack 23d is installed inside the housing 22, the drive motor 23c is installed at the bottom of the lateral sliding block 23b and moves synchronously with the lateral sliding block 23b, and the output shaft of the drive motor 23c is connected to the drive rack 23d via gears to complete the driving of the lateral sliding block 23b.
[0047] In some embodiments, the clamping mechanism 2 further includes a secondary claw 25, which is mounted on the side wall of the housing 22 via an auxiliary hand 26; in short, the secondary claw 25 is mounted on the side wall of the housing 22 via an auxiliary hand 26 and is responsible for assisting in unlocking the twist lock, such as by turning the pin.
[0048] In some embodiments, the longitudinal sliding pair 24 includes a longitudinal guide rail 24a and a longitudinal sliding block 24b. The longitudinal guide rail 24a is mounted on top of the transverse sliding block 23b, and the longitudinal sliding block 24b is slidably disposed on the longitudinal guide rail 24a. The clamping claw 21 is mounted on top of the longitudinal sliding block 24b. In short, the longitudinal guide rail 24a is mounted on the transverse sliding block 23b, and the longitudinal sliding block 24b is slidably disposed on the longitudinal guide rail 24a to complete the horizontal displacement of the clamping claw 21.
[0049] In some embodiments, an electric push rod 24c is provided on the top of the transverse sliding block 23b, and the movable end of the electric push rod 24c is connected to the longitudinal sliding block 24b through a connecting block; in short, the electric push rod 24c is provided on the top of the transverse sliding block 23b, and its movable end is connected to the longitudinal sliding block 24b to complete the driving of the longitudinal sliding block 24b.
[0050] In some embodiments, the unlocking mechanism includes a lifting joint 32 and a rotary motor 33. The lifting joint 32 is disposed on the side wall of the housing 22, the rotary motor 33 is mounted on the moving end of the lifting joint 32, and the unlocking claw 31 is mounted on the output shaft of the rotary motor 33. In short, the rotary motor 33 is responsible for rotating the unlocking claw 31 to rotate the torsion lock, and the lifting joint 32 is responsible for driving the rotary motor 33 to rise and fall, thereby driving the unlocking claw 31 to a suitable position.
[0051] In some embodiments, the unlocking claw 31 includes a pair of pins 31a, which are adapted to abut against the shape of the torsion lock's latch to rotate and unlock; in short, by abutting the shape of the torsion lock with a pair of pins 31a, the torsion lock's latch is rotated, thereby releasing the lock from the container.
[0052] In some embodiments, the sensor 41 is mounted on the side wall of the housing 22 via a bracket; in short, the sensor 41 is mounted on the side wall of the housing 22 and faces the front end of the housing 22 to detect torsion lock.
[0053] In the description of the embodiments of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0054] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, terms such as "first," "second," and other numerical terms used herein do not imply order or sequence unless expressly indicated herein. Therefore, without departing from the teachings of the exemplary embodiments, the first element, component, region, layer, or segment discussed above may be referred to as the second element, component, region, layer, or segment.
[0055] Spatially relative terms, such as “inside,” “outside,” “below,” “below,” “down,” “above,” “up,” etc., may be used herein to describe the relationship between one element or feature illustrated in the figures and another element or feature. In addition to the orientations depicted in the figures, spatially relative terms may be intended to cover different orientations of the device in use or operation. For example, if the device in the figure is flipped, an element described as “below” or “below” other elements or features would be oriented as “above” other elements or features. Thus, the example term “below” can cover both above and below orientations. The device may be oriented in other ways (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein are interpreted accordingly.
[0056] In the above discussion, unless otherwise stated, when used to describe numerical values, the terms “about,” “approximately,” “basically,” etc., indicate a change of + / - 10% in that value.
[0057] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
