In this embodiment, the portion of the extension portion 321 extending out of the base 31 may be configured as a plate structure, for example, as shown in the drawing, the extension portion 321 may be configured as a plate structure as a whole, and the notch 3211 may be configured to form the hooking portion 322, and provide a space for the hooking portion 322 to cooperate with the unhooking portion of the hanging section 22 of the hook lifting lever 2, so that, in implementation, the shape of the notch 3211 may be determined according to practical requirements on the basis of meeting the two points.

In order to rotatably connect the retractor member 32 to the base 31, there are various embodiments, for example, the retractor member 32 may be connected to the base 31 by an existing rotatable connection structure such as a hinge, or the like, the retractor member 32 may be rotatably connected to the base 31 by a connection structure configured to be engaged with each other, for example, the retractor member 32 is configured with a first engagement portion, the base 31 is configured with a second engagement portion adapted to the first engagement portion, and the retractor member 32 may be rotatably connected to the base 31 by engagement of the first engagement portion with the second engagement portion, wherein the first engagement portion may be a hinge hole configured to the retractor member 32, and the second engagement portion may be a hinge post configured to the base 31, the hinge post being inserted into the hinge hole and rotatable with respect to the hinge hole. On the contrary, when the first fitting portion adopts the hinge post and the second fitting portion adopts the hinge hole, the same effect can be achieved. As another example, the first mating portion and the second mating portion may respectively adopt hinge holes, so that the retractor member 32 may be rotatably connected to the base 31 by using a connection shaft 41 adapted to the hinge holes, the connection shaft 41 may be a pin shaft, a stepped shaft, a screw, or the like, as shown in fig. 2 to 5, in this embodiment, the extension 321 of the retractor member 32 is configured with the hinge holes, the base 31 is configured with the hinge holes 313, and the hinge holes 313 of the base 31 are internally provided with the bearings 42, the retractor member 32 is sleeved on the connection shaft 41 through the hinge holes and is fixed to the connection shaft 41 by bolts, and the connection shaft 41 is connected to the bearings 42, so that the retractor member 32 may rotate relative to the base 31.

As shown in fig. 2 to 5, in this embodiment, the lifting structure is rotatably connected to the base 31, so that the lifting structure can rotate relative to the base 31, and the lifting structure is mainly used for lifting the hook lifting lever 2, so that the hook lifting lever 2 can be separated from the constraint of the flat groove 102 in a lifting manner, and the purpose of unlocking the hook lifting lever 2 is achieved. In a simple embodiment, the lifting structure comprises a lifting element 33, the lifting element 33 is rotatably connected to the base 31, one end of the lifting element 33 extends out of the base 31 so as to be matched with the hook lifting rod 2, and the lifting element 33 is mainly used for contacting the straight section 21 in the hook lifting rod 2 and for lifting the hook lifting rod 2, so that when the hook is unhooked, the lifting element 33 can be driven upwards by using the position adjusting device 7 so as to lift the hook lifting rod 2 by using the lifting element 33 and separate the lifting element from the flat groove 102, and unlocking of the hook lifting rod 2 is realized. In implementation, the lifting member 33 may be a rod-shaped structure, a plate-shaped structure, a combination of a rod-shaped structure and a plate-shaped structure, and other shaped structures, for example, as shown in fig. 2, the lifting member 33 is a rod-shaped structure.

In this embodiment, the mounting shaft and the base 31 may be integrally formed, and the mounting shaft may be fixed to the base 31 by welding, bolting, screwing, riveting, or the like.

As another example, as shown in fig. 4 and 5, the lifting structure further includes a rotating shaft 34, one end of the lifting member 33 may be connected to the rotating shaft 34, meanwhile, the base 31 is configured with an assembly hole 312 adapted to the rotating shaft 34, and the rotating shaft 34 is rotatably connected to the assembly hole 312, so as to implement rotatable installation of the lifting structure. In practice, the bearing 42 may be mounted in the mounting hole 312, and the rotating shaft 34 is connected to an inner ring of the bearing 42. It should be understood that, in implementation, the assembly hole 312 may be formed in the bearing seat 43, and the bearing seat 43 is fixed to the base 31, and at this time, the bearing seat 43 and the base 31 may be collectively referred to as the base 31, and the bearing 42 is assembled in the bearing seat 43, which also achieves the same effect, and will not be described herein. In practice, the lifting element 33 and the shaft 34 may be integrally formed, and the shaft 34 and the lifting element 33 may be formed in an L-shape. In this embodiment, the lifting member 33 is detachably mounted on the rotating shaft 34, so that not only is the mounting of the lifting member 33 convenient, but also the relative position relationship between the lifting member 33 and the hook member 32 is convenient to be adjusted according to actual requirements, so as to meet the requirements of different unhooking occasions. For example, as shown in fig. 4 and 5, in this embodiment, the lifting structure further includes an adjusting nut 5, one end of the lifting member 33 is configured with a mounting hole, the rotating shaft 34 is configured with a step 341, the step 341 may preferably adopt an annular structure, at this time, the rotating shaft 34 is a stepped shaft, a shaft section between the step 341 and an end of the rotating shaft 34 is an assembly shaft section, the assembly shaft section is adapted to the mounting hole, and the assembly shaft section is configured with an external thread adapted to the adjusting nut 5, so that the lifting member 33 may be sleeved on the assembly shaft section through the mounting hole and may be pressed against the step 341 through the adjusting nut 5, and in practical use, the lifting member 33 may be conveniently fixed and loosened so as to adjust the relative positional relationship between the lifting member 33 and the drag hook member 32.

In this embodiment, the buffer component is connected to the base 31, and the buffer component mainly acts on the lifting structure, so that when the lifting structure rotates under the action of external force, the buffer component blocks the lifting structure from rotating, and the lifting structure presses the buffer component to elastically deform, so that the elastic potential energy of the buffer component is increased, and elasticity is generated or larger elasticity is generated. In the in-service use, through the cooperation of lifting structure and buffer component, not only can flexible unblock hook lifting lever 2, can play the effect of buffering to lifting structure moreover, both can prevent that lifting structure and hook lifting lever 2 from taking place rigid collision, can prevent again that the damage is used for driving this unhook device 3's position control device 7, play the effect of protecting position control device 7, for example, hook lifting lever 2 seat 10 and hook lifting lever 2 are usually exposed outside, the environment is abominable, rust easily takes place, lead to hook lifting lever 2 card to be difficult for taking off in flat groove 102, the process of unblock hook lifting lever 2 is easy because of the load is suddenly too big burns out the motor in the position control device 7, and between the buffer component has been disposed, can play buffering and protection's effect, make the load of motor slowly increase in the position control device 7, thereby can effectively protect position control device 7. In addition, after the lifting structure breaks away from the hook lifting rod 2, the elastic potential energy of the buffer component is released, so that the lifting structure can be driven to quickly return to the initial position, the automatic reset function of the lifting structure is realized, and the unhooking efficiency is improved.

In practice, the cushioning member may have various embodiments, for example, the cushioning member may employ an elastic pad, where the elastic pad may be disposed on the base 31 and located on a rotation path of the lifting structure, and the elastic pad has a required thickness to meet a requirement of rotation of the lifting structure, and when the lifting structure rotates relative to the base 31, the lifting structure presses the elastic pad, and the elastic pad is elastically deformed. As another example, the buffer member may be a spring, for example, the spring may be a torsion spring, the torsion spring may be sleeved on the aforementioned mounting shaft or the rotating shaft 34 for implementing rotatable connection, for example, as shown in fig. 4 and 5, the spring may be a first torsion spring 61, the first torsion spring 61 is sleeved on the rotating shaft 34, one end of the first torsion spring 61 is restrained on the base 31 or a member fixed on the base 31, the other end of the first torsion spring 61 is restrained on the rotating shaft 34 or a fixed member restrained on the rotating shaft 34, for example, as shown in fig. 4 and 5, the rotating shaft 34 is provided with a hoop member 342 (that is, a member clasped on the rotating shaft 34 and rotates synchronously with the rotating shaft 34), and the end of the first torsion spring 61 may be restrained on the hoop member 342. In use, when the lifting structure is rotated by external force, the elastic potential energy of the first torsion spring 61 increases. For another example, the spring may also be an extension spring, where one end of the extension spring is connected to the base 31 and the other end is connected to the lifting structure, so that when the lifting structure rotates under the action of external force, the extension spring can be driven to extend. In addition, the spring may be a compression spring, one end of which is connected to the base 31, and the other end of which is connected to the lifting structure and is located in a rotation path of the lifting structure, so that the compression spring can be compressed when the lifting structure rotates under the action of external force.

It will be appreciated that in practice, it is desirable to rationally select and set the cushioning component such that when the lifting structure is utilized to unlock the hook lever 2, the lifting structure can be rotated a certain angle relative to the base 31, but not rotated too much angle so as not to affect the lifting structure to lift the hook lever 2.

In a more perfect scheme, the base 31 is further provided with a first limiting part 314 adapting to the lifting structure, the first limiting part 314 is arranged on a rotating path of the lifting structure and is used for limiting and restraining the lifting structure, so that the lifting structure can be pressed down on the first limiting part 314 under the action of the elastic force of the buffer component in the initial state, for example, as shown in fig. 4 and 5, the hoop component 342 can be pressed down on the first limiting part 314 under the action of the elastic force of the buffer component in the initial state, the first limiting part 314 can limit the lifting structure to reversely rotate, and the effect of positioning the initial position of the lifting structure can be achieved through the cooperation of the buffer component and the first limiting part 314, so that the lifting structure is always positioned at the initial position in the initial state, and the lifting structure can automatically return to the initial position under the action of the buffer component after the completion of the unhooking, so that the unhooking precision and the unhooking efficiency can be improved.

In practice, the lifting structure (at least the lifting element 33) may be preferentially disposed above the hook element 32, as shown in fig. 2-5, so that the lifting structure and the hook element 32 may be respectively and simultaneously engaged with the straight section 21 and the drop section 22 of the hook lifting lever 2, so that the operation of unlocking the hook lifting lever 2 may be better engaged with the operation of unlocking the coupler, so that the unlocking process is smoother, consumes less time, and is beneficial to improving the unhooking efficiency. In addition, the lifting member 33 and the retractor member 32 may have a more optimal positional relationship, as shown in fig. 2 to 5, and in this embodiment, the lifting member 33 and the retractor member 32 may be parallel to each other and horizontally installed, as shown in fig. 4 and 5.

In use, the present unhooking device 3 can be detachably mounted on the position adjusting device 7 through the mounting portion 311 on the base 31, as shown in fig. 6 and 7, so as to adjust the spatial position of the present unhooking device 3 by using the position adjusting device 7, so as to cooperate with the hook lifting rod 2 to realize unhooking. The position adjusting device 7 may be an existing manipulator (i.e., a multi-axis robot), the position adjusting device 7 may also be an XYZ three-axis manipulator, and the XYZ three-axis manipulator is provided with a telescopic fork, and the base 31 of the unhooking device 3 is mounted on the telescopic fork.

The position adjusting device 7 may be mounted outside the side surface of the track of the vehicle cabin 1, may be mounted at a fixed position, or may be mounted on a moving platform. When unhooking, the position adjusting device 7 can send the unhooking device 3 into the gap 103 between two adjacent carriages 1 from the side surfaces of the carriages 1, so that the unhooking device 3 can face the hook lifting rod 2 arranged transversely along the carriages 1, as shown in fig. 6; the position adjustment device 7 can then drive the unhooking device 3 to move in the transverse direction of the car 1 so that the hooking portion 322 of the hooking member 32 hooks the drop section 22 of the hook lifting lever 2, as shown in fig. 6, and so that the lifting member 33 is located below the straight section 21 of the hook lifting lever 2; then the position adjusting device 7 drives the unhooking device 3 to move upwards along the height direction of the carriage 1 so as to lift the hook lifting rod 2 by using the lifting part 33, so that the hook lifting rod 2 is separated from the flat groove 102, and the purpose of unlocking the hook lifting rod 2 is achieved as shown in fig. 7; then, the position adjusting device 7 drives the unhooking device 3 to translate a distance along a direction away from the hook lifting lever 2 (i.e. along the length direction of the carriage 1), so that the lifting part 33 is separated from the hook lifting lever 2, and then the position adjusting device 7 drives the unhooking device 3 to move upwards along the height direction of the carriage 1, so that the hook lifting lever 2 is driven by the hook pulling part 32 to rotate upwards along the sagging section 22 of the hook lifting lever 2, and when the hook lifting lever 2 rotates to a certain angle, the unlocking of the hook is completed, so that the purpose of unhooking a hook is achieved. This unhooking mode is completely different from the existing unhooking mode, and the unhooking efficiency is higher, unhooking success rate is higher, in addition, this unhooking device 3 still is applicable to the condition that needs unblock hook lifting lever 2 earlier, of course, to the condition that does not need unblock hook lifting lever 2 earlier, this unhooking device 3 is also applicable, and this is not repeated here.

Example 2

In order to further improve the unhooking precision and unhooking efficiency of the unhooking device 3, the unhooking device 3 provided in this embodiment may not have direct contact between the hook member 32 and the base 31, so that there is no friction between the hook member 32 and the base 31, but in order to prevent the hook member 32 from rotating freely relative to the base 31, the unhooking device further includes a reset member connected to the base 31 and acting on the hook member 32, where when the hook member 32 rotates under the action of external force, for example, when the hook member 32 rotates properly under the action of gravity of the sagging section 22, the elastic potential energy of the reset member increases. The configuration of the reset component can balance the external force borne by the drag hook component 32, can prevent the drag hook component 32 from interfering with and blocking the sagging section 22, can prevent the drag hook component 32 from freely rotating, ensures that the drag hook component 32 can drive the sagging section 22 of the hook lifting rod 2 to rotate, and realizes more flexible, coordinated and stable unhooking action. On the other hand, after unhooking is completed, the elastic potential energy of the reset component is automatically released, and the drag hook component 32 can be driven to rotate reversely, so that the drag hook component 32 automatically returns to the initial position, the automatic reset function is achieved, the next unhooking action can be rapidly performed, and the unhooking efficiency can be improved. In addition, the reset component can also play a role in buffering and damping.

In practice, the restoring member may have various embodiments, for example, the restoring member may employ an elastic pad, where the elastic pad may be disposed on the base 31 and located on a rotation path of the retractor member 32, and the elastic pad has a required thickness to meet a requirement of rotation of the retractor member 32, and when the retractor member 32 rotates relative to the base 31, the retractor member 32 presses the elastic pad, and the elastic pad elastically deforms. In a preferred embodiment, the restoring member may employ a spring, one end of which is restrained to the base 31 and the other end of which is restrained to the hooking member 32, and the elastic force of the spring is gradually increased when the hooking member 32 is rotated forward by an external force. In practice, the spring may be a torsion spring, which may be sleeved on the hinge post or the connecting shaft 41 for implementing rotatable connection, for example, as shown in fig. 8 and 9, the reset component is a second torsion spring 62, one end of the second torsion spring 62 is restrained on the base 31 or a component fixed on the base 31 (such as a lug or a restraint block mounted on the base 31), and the other end of the second torsion spring 62 is restrained on the drag hook component 32 or a fixed component restrained on the drag hook component 32 (such as a lug or a restraint block mounted on the drag hook component 32), so that when the drag hook component 32 rotates under the action of external force, the elastic potential energy of the second torsion spring 62 increases. For another example, the spring may be an extension spring, where one end of the extension spring is connected to the base 31 and the other end is connected to the hook member 32, so that the extension spring can be driven to extend when the hook member 32 rotates forward. For another example, the spring may also be a compression spring, where one end of the compression spring is connected to the base 31 and the other end is connected to the hook member 32, so that the hook member 32 can drive the compression spring to compress when rotating forward under the action of external force.

In a more optimized scheme, the base 31 is further provided with a second limiting portion 315 adapted to the hook component 32, as shown in fig. 8 and 9, the second limiting portion 315 is used for limiting and restraining the hook component 32, so that the hook component 32 is kept pressed against the second limiting portion 315 under the action of the resetting component in the initial state (i.e. before or after unhooking), in this scheme, the second limiting portion 315 can limit the hook component 32 to reversely rotate, and through the cooperation of the hook component 32 and the second limiting portion 315, the function of positioning the initial position of the hook component 32 can be achieved, and the hook component 32 is always located at the initial position in the initial state, so that unhooking precision can be improved. As shown in fig. 8 and 9, in the present embodiment, the second limiting portion 315 is a limiting block disposed on the base 31 and located above the retractor member 32, so as to limit and constrain the retractor member 32 at a horizontal position.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any person skilled in the art will readily recognize that variations or substitutions are within the scope of the present utility model.
