First embodiment
Referring to fig. 1, the present embodiment provides a container protection device 100 for air rail freight, where the container protection device 100 includes: two or more twist lock fixtures 130 and two or more cantilever fixtures 120.
The spin lock fixing device 130 is arranged on the lower side surface of the vehicle body 110 of the air rail train, and the spin lock fixing device 130 is used for matching with a lock hole preset on the upper side surface of the container 301 to fix the container 301; the twist-lock fastener 130, when engaged with a keyhole in a container 301, allows the container 301 to be suspended below the body 110 of the air rail train.
In this embodiment, the twist-lock fixing device 130 may have various specific embodiments, such as:
1. the twist-lock fastening device 130 may be a snap assembly 130a, the snap assembly 130a is hinged to the bottom of the vehicle body 110, and a protrusion 130 a' may be provided at the end of the snap assembly 130 a. In this embodiment, when the buckle assembly 130a needs to be combined with the lock hole, the buckle assembly 130a can be rotated towards the edge of the lock hole, so that the protrusion 130 a' on the buckle assembly 130a catches the container 301 to prevent the container from falling off, as shown in fig. 2.
2. The twist-lock fixture 130 may be a stationary screw 130b coupled to a power source, and the stationary screw 130b may be rotated, for example, by a servo motor to control the rotation of the stationary screw 130 b. In this embodiment, the locking hole of the container 301 should have an internal thread matching with the fastening screw 130b, and the container 301 can be loosened or fixed by controlling the loosening or tightening of the fastening screw 130b, as shown in fig. 3.
In order to make the container 301 more stable and reliable, the following embodiment 3 is provided in this embodiment, please refer to fig. 4:
3. the twist-lock fixture 130 includes: the asynchronous motor 131, the connecting rod 132 and the first locking head 133 refer to fig. 4.
The asynchronous motor 131 may be a three-phase asynchronous motor, and the asynchronous motor 131 is used to push and pull the connecting rod 132 to rotate the first lock head 133. Connecting rods 132 are connected to both sides of the asynchronous motor 131, and the ends of the two connecting rods 132 far away from the asynchronous motor 131 are connected with first locking heads 133. The first locking head 133 can be rotated, and the first locking head 133 can be controllably rotated under the control of the asynchronous motor 131. The connection structure of the components in the twist lock fixing device 130 is not limited:
for example, the asynchronous motor 131 may be connected to a rotating part, and one end of the link 132 is rotatably connected to a section of the rotating part, and the other end of the link 132 is rotatably connected to a section of the first locking head 133, as shown in fig. 5.
For another example, the asynchronous motor 131 may be connected to a rotating part, and one end of the connecting rod 132 is hinged to a side of the rotating part, and the other end of the connecting rod 132 is hinged to a side of the first locking head 133, as shown in fig. 6.
In addition, in order to fix the container 301 better, the specific structure of the first locking head 133 may be a T-shaped structure, or may be an L-shaped structure, which is not limited. The locking hole matched with the first locking head 133 can be of a strip-shaped structure, and when the first locking head 133 of an L-shaped or T-shaped structure rotates, locking can be formed, so that the first locking head 133 is prevented from falling off from the locking hole, and the container 301 is protected and fixed, as shown in fig. 7.
In addition, in order to determine the real-time state (locking state, unlocking state) of the twist lock fixing device 130, limit switches 134 may be disposed on both sides of the asynchronous motor 131, the limit switches 134 are used to detect the displacement (stroke) of the connecting rod 132, further determine the pushing condition of the connecting rod 132 to the first lock head 133, determine the current real-time state of the first lock head 133, and transmit the real-time state to a master control system in the form of an electrical signal, wherein the master control system is used to control the actions of the twist lock fixing device 130 and the cantilever fixing device 120.
Specifically, for each connecting rod 132, the unlocking state of the first locking head 133 can be determined by the limit switch 134 when the connecting rod 132 is located at the first position, and the locking state of the first locking head 133 can be determined by the limit switch 134 when the connecting rod 132 is located at the second position (different from the first position); the first and second positions are the two extreme positions of the limit switch 134.
Further, in order to realize the automatic control of the twist-lock fixing device 130, a detection sensor may be provided for detecting the position of the container 301. The detection sensor may be: radar sensors, ultrasonic sensors, infrared sensors, and the like.
