the vehicle body 1 is assembled on the traveling frame 2, and the vehicle body 1 can move on the traveling frame 2, so that the vehicle body 1 is configured on the traveling frame 2 in a horizontal distribution state or in a required inclination state after being turned over, wherein,

when the vehicle body 1 is sorted and walks along the turning area of the sorting track 23, the vehicle body is turned on the traveling carriage 2 and is in a required inclined distribution state;

after passing through the turning area of the sorting rail 23, the vehicle body 1 is turned over on the traveling carriage 2 and is maintained in a horizontally distributed state.

Specifically, the sorting trolley comprises a trolley frame 2 and a trolley body 1 which is connected with the trolley frame 2 in an adaptive mode, wherein the trolley frame 2 enables the whole sorting trolley to walk along the sorting track 23 in a sorting mode, the trolley body 1 is used for supporting and transporting articles to be sorted, the sorting trolley can be consistent with the prior art in the sorting walking mode along the sorting track 23 through the trolley frame 2, and when the trolley frame 2 walks in the sorting track 23, the trolley body 1 synchronously walks on the sorting track 23 along with the trolley frame 2 so as to convey the articles to be sorted to a required sorting position. As can be seen from the above description, when there are one or more turning areas on the sorting track 23, the speed of the carriage 2 and the vehicle body 1 passing through the turning areas is too high, which causes the package-throwing phenomenon, that is, the articles to be sorted on the vehicle body 1 fly off the vehicle body 1.

In the embodiment of the invention, the vehicle body 1 can move on the travelling crane frame 2 so as to arrange the vehicle body 1 on the travelling crane frame 2 in a horizontal distribution state or in a required inclined state after being turned over; when the vehicle bodies 1 are configured on the traveling carriage 2 to be capable of turning to a required inclined state, namely, when the vehicle bodies 1 are sorted and travel along the turning area of the sorting track 23, the vehicle bodies 1 are obliquely distributed on the traveling carriage 2, so that the traveling carriage 2 and the vehicle bodies 1 obliquely distributed on the traveling carriage 2 are used for sorting and traveling along the turning area of the sorting track 23. During specific work, when walking along the regional letter sorting of turning of letter sorting track 23, because automobile body 1 slopes on crane frame 2, utilize the automobile body 1 of tilt state to place in waiting to sort article on the automobile body 1 provide the support, increase and wait to sort the gravity component of article on automobile body 1, overcome the centrifugal force of waiting to sort article to can significantly reduce get rid of the package phenomenon when high-speed passing turn region.

For the sorting trolley, the trolley body 1 is inclined on the travelling carriage 2, and the travelling carriage 2 still keeps a horizontal distribution state in the sorting track 23, namely the sorting travelling of the travelling carriage 2 in the sorting track 23 is not influenced. The turning area of the sorting track 23 is arc-shaped, when the vehicle body 1 is in a tilting state on the traveling frame 2 and travels along the turning area in a sorting manner, the tilting state of the vehicle body 1 on the traveling frame 2 is adapted to the shape of the turning area, specifically, the shape adapted to the turning area means that the vehicle body 1 is in a state of being high outside and low inside on the traveling frame 2, and the state of being high outside and low inside means that the end of the vehicle body 1 corresponding to the outside of the turning area is higher than the end of the vehicle body 1 corresponding to the inside of the turning area.

When the vehicle body 1 is in the inclined state on the traveling frame 2 and is matched with the shape of the turning area, when the vehicle body travels at a high speed along the turning area, the vehicle body 1 in the inclined state is utilized to support the articles to be sorted on the vehicle body 1, the gravity component of the articles to be sorted on the vehicle body 1 is increased, the centrifugal force of the articles to be sorted is overcome, and therefore the bag throwing phenomenon when the vehicle body travels at a high speed along the sorting turning area 7 can be effectively prevented. The articles to be sorted can be in common forms such as packages, and can be determined according to requirements. When walking along the turn region, automobile body 1 slopes the distribution state on driving frame 2 to the transportation of treating the letter sorting article is the standard for not influencing, both can prevent promptly and get rid of the phenomenon of package, will avoid again treating that the letter sorting article is direct from automobile body 1 landing.

After passing through the turning area of the sorting track 23, the sorting trolley enters the straight area of the sorting track 23, and according to the characteristics of the straight area, the trolley body 1 needs to be kept in a horizontal state on the trolley frame 2, otherwise, when the trolley body 1 is in an inclined state, the objects to be sorted are easy to directly slide off the trolley body 1. Thus, after passing through the turning area of the sorting rail 23, the vehicle body 1 is turned over on the traveling carriage 2 and is maintained in a horizontally distributed state.

In summary, the car bodies 1 of the sorting trolleys are configured to be distributed on the travelling crane frame 2 in an inclined manner, that is, the car bodies 1 of the sorting trolleys have the capability of turning over and inclining on the travelling crane frame 2, and the car bodies 1 are controlled to turn over to the required inclining state on the travelling crane frame 2 only when the sorting trolleys run along the turning area of the sorting track 23; at the straight region of letter sorting track 1, automobile body 1 needs to keep horizontal distribution state on driving frame 2 to along all letter sorting walking in-process of letter sorting track 23, realize treating the effective support of letter sorting article, avoid the packet phenomenon of getting rid of when the high-speed bending of letter sorting dolly, improve speed and the letter sorting efficiency of letter sorting dolly when the letter sorting. In general, the carriages 2 are horizontally distributed in the sorting track 23, whether in a straight zone or in a turning zone.

Further, the vehicle body 1 comprises a first vehicle body end and a second vehicle body end corresponding to the first vehicle body end, and the first vehicle body end and/or the second vehicle body end of the vehicle body 1 are/is configured to be capable of being turned away from the traveling frame 2;

driving a first end of the vehicle body 1 or a second end of the vehicle body 1 to turn over on the traveling frame 2 in a direction away from the traveling frame 2, so that the vehicle body 1 is in a required inclined distribution state on the traveling frame 2;

when the vehicle body 1 is in a horizontal distribution state on the traveling crane frame 2, the vehicle body 1 and the traveling crane frame 2 are mutually locked through a locking connection mechanism.

In the embodiment of the invention, a vehicle body 1 is provided with a first vehicle body end and a second vehicle body end, wherein the first vehicle body end is opposite to the second vehicle body end, and the first vehicle body end and the second vehicle body end of the vehicle body 1 are positioned on two sides of an axis of a travelling frame 2 in the advancing and travelling direction along a sorting track 1; when the traveling crane frame 2 is located in the sorting track 23, the first end and the second end of the vehicle body 1 respectively correspond to the two track bodies of the sorting track 23, the two track bodies are the outer track body of the sorting track 23 and the inner track body corresponding to the outer track body, and the specific situations of the two track bodies in the sorting track 23 are consistent with the existing situation, and are not repeated here.

In specific implementation, the sorting track 23 is annular, but in different area positions, a turning area can be set, so that the occupied area can be saved. For an annular sorting track 23, for a flat area, the outer track body is a track body corresponding to the outer side of the entire sorting track 23, and the inner track body is a track body corresponding to the inner circle of the sorting track 23. And for the turning area, the track body on the outer side of the turning area is the track body corresponding to the outer arc of the turning area, and the track body on the inner side of the turning area is the track body corresponding to the inner arc of the turning area.

In order to adapt to sorting travel in the sorting track 23 having a turning area, the first end of the vehicle body 1 may be disposed so as to be turnable in a direction away from the traveling frame 2, or both the first end and the second end of the vehicle body 1 may be disposed so as to be turnable in a direction away from the traveling frame 2. When the first end of the vehicle body and the second end of the vehicle body both have the turning capacity to be far away from the traveling crane frame 2, when the vehicle travels along the turning area, only the first end of the vehicle body or only the second end of the vehicle body turns and inclines to be far away from the traveling crane frame 2, the first end of the vehicle body or the second end of the vehicle body turns and inclines, and the first end of the vehicle body or the second end of the vehicle body is specifically related to the shape of the turning area required to pass through at present and the state of the first end of the vehicle body and the second end of the vehicle body 1 corresponding to the sorting track 23, and the object to be sorted can pass through the turning area quickly and stably.

After the overturning and inclining capacity between the first end and the second end of the vehicle body and the traveling frame 2 is set, the first end of the vehicle body 1 or the second end of the vehicle body 1 is driven to overturn in the direction far away from the traveling frame 2 on the traveling frame 2, so that the vehicle body 1 is in a required inclined distribution state on the traveling frame 2, namely, the vehicle body 1 is sorted and travels along the turning area of the sorting track 23 in the inclined distribution state on the traveling frame 2. Generally, when the first end of the vehicle body 1 is turned away from the traveling frame 2, the second end of the vehicle body 1 moves toward the traveling frame 2; similarly, when the second end of the vehicle body 1 is turned away from the traveling frame 2, the first end of the vehicle body 1 moves toward the traveling frame 2.

In the embodiment of the present invention, the tilting in the direction away from the traveling frame 2, specifically, the position after the tilting is able to cross the position state of the vehicle body 1 in the horizontal state, for example, the tilting in the direction away from the traveling frame 2 is able to drive the first end of the vehicle body to tilt in the direction away from the traveling frame 2, specifically, the position after the tilting is able to cross the first end of the vehicle body 1 in the horizontal state, and the crossing specifically means the position after the tilting is located outside the position of the first end of the vehicle body in the horizontal state, and in the following description, the specific case away from the traveling frame 2 is consistent with the description, and the description may be specifically referred to herein.

In order to ensure the reliability of conveying articles to be sorted when the articles are sorted and walk in a straight area, the vehicle body 1 and the travelling crane frame 2 need to be locked with each other through a locking connection mechanism. Therefore, the locking connection mechanism locks the vehicle body 1 and the traveling rack 2 to each other in the straight area of the sorting track 23, and releases the corresponding locking state between the vehicle body 1 and the traveling rack 2 when the sorting traveling along the turning area is required, so that the vehicle body 1 can be in the required inclined distribution state on the traveling rack 2 when the sorting traveling along the turning area is required.

Further, the locking connection mechanism is in adaptive connection with a frame connection body in the traveling frame 2;

the second end of the vehicle body 1 is configured to be capable of turning in a direction away from the traveling frame 2, and comprises a second end turning rotation center for matching with the turning of the second end of the vehicle body;

the locking connecting mechanism comprises a locking first connecting mechanism used for locking the second end of the vehicle body 1 and the second end of the connecting body of the vehicle frame connecting body, and after the locking state of the locking first connecting mechanism to the second end of the vehicle body 1 and the second end of the vehicle frame connecting body is released, the second end of the vehicle body 1 can turn around the turning rotating center of the second end of the vehicle body to the direction far away from the traveling frame 2.

In the embodiment of the invention, the traveling frame 2 is provided with the frame connecting body, and the traveling frame 2 can be in adaptive connection with the vehicle body 1 by utilizing the frame connecting body, wherein the adaptive connection can particularly meet the requirements that the vehicle body 1 can be overturned on the traveling frame 1 to be in an inclined distribution state and can also be kept in a horizontal distribution state on the traveling frame 2.

As can be seen from the above description, in a specific operation, the vehicle body 1 may be tilted in a single-end manner on the traveling carriage 2, and the single-end tilting may specifically be: the second end of the vehicle body 1 is configured to be able to turn in a direction away from the traveling frame 2, and at this time, the first end of the vehicle body 1 cannot be driven to turn in a direction away from the traveling frame 2, and of course, when the second end of the vehicle body 1 is driven to turn in a direction away from the traveling frame 2, the first end of the vehicle body 1 correspondingly slightly approaches the traveling frame 2. The specific situation that the vehicle body 1 is turned over and inclined on the traveling frame 2 at one end is based on the condition that the vehicle body 1 can be turned over on the traveling frame 2 and is in all inclined states. When the vehicle body 1 needs to be turned on the traveling frame 2 in a tilted distribution, a turning driving force is generally required to be provided, for example, a turning driving force is applied to the second end of the vehicle body, so that the second end of the vehicle body 1 can be tilted away from the traveling frame 2. As for the case of the tumble driving force, a detailed explanation is made below.

In specific implementation, when only the second end of the vehicle body is configured to be capable of being turned in a direction away from the traveling frame 2, the turning device further comprises a turning and rotating center of the second end of the vehicle body, wherein the turning and rotating center of the second end of the vehicle body is used for matching with the turning of the second end of the vehicle body 1; namely, the second end of the vehicle body can rotate around the overturning rotation center of the second end of the vehicle body, and is far away from the traveling frame 2 or close to the traveling frame 2 after rotating. When the second end of the vehicle body is close to the traveling frame 2 around the turning and rotating center of the second end of the vehicle body, the first end of the vehicle body is in a state of being far away from the traveling frame 2, but because the first end of the vehicle body cannot cross the position of the first end of the vehicle body in a horizontal state, the turning state of the first end of the vehicle body far away from the traveling frame 2 is not required to be driven to turn and incline in a direction far away from the traveling frame 2 in the invention.

Since the first end of the vehicle body 1 cannot be actively driven to turn in the direction away from the traveling frame 2, the locking connection mechanism includes a first locking connection mechanism 26 for locking the second end of the vehicle body 1 and the second end of the connection body of the frame connection body, that is, the second end of the vehicle body 1 can be locked on the traveling frame 2 by the first locking connection mechanism 26, and at this time, the vehicle body 1 is horizontally distributed on the traveling frame 2. According to the specific situation of locking the first connecting mechanism 26, after the locking state of the first connecting mechanism 26 on the second end of the vehicle body 1 and the second end of the frame vehicle body connecting body is released, the second end of the vehicle body 1 can turn around the turning center of the second end of the vehicle body to turn in the direction away from the traveling frame 2.

Further, in order to form a vehicle body second end turning and rotating center, in the embodiment of the invention, a vehicle body first end of a vehicle body 1 is hinged with a connecting body first end of a frame connecting body, so that the vehicle body second end turning and rotating center is formed by utilizing a hinged connecting part of the vehicle body first end and the connecting body first end;

when passing through the turning area of the sorting rail 23, the vehicle body 1 cooperates with the turning area of the sorting rail 23 so that the first coupling mechanism 26 is kept in the unlocked state during passing through the turning area of the sorting rail 23.

As shown in fig. 1, 2 and 5, in order to specifically match the vehicle body 1 and the traveling carriage 2 in the sorting cart when only the second end of the vehicle body is disposed so as to be turnable in a direction away from the traveling carriage 2, a specific case of forming the second turning rotation center of the vehicle body and locking the first connecting mechanism 26 will be explained in detail.

As shown in fig. 4, for the vehicle body 1, a driving roller 21 and a driven roller 22 are further arranged in the vehicle body 1, the driving roller 21 and the driven roller 22 are respectively located at two ends of the vehicle body 1, and the driving roller 21 and the driven roller 22 can be connected in an adaptive manner through the vehicle body belt 3. In fig. 4, the driving roller 21 is disposed at the first end of the vehicle body 1, the driven roller 22 is disposed at the second end of the vehicle body 1, the support for the article to be sorted can be realized through the vehicle body belt 3, and when the driving roller 21 drives the vehicle body belt 3 to rotate, the article to be sorted on the vehicle body belt 3 can be conveyed to a required position, so that the article to be sorted can be driven to be separated from the vehicle body 1.

In addition, an active roller driver 18 is further disposed in the vehicle body 1, the active roller driver 18 can be used to drive the active roller 21 to work, the active roller driver 18 may specifically adopt a conventional form, and the specific working manner of the active roller driver 18 driving the active roller 21 may be consistent with the conventional form, which is known to those skilled in the art and is not described herein again.

Further, when the first end of the vehicle body 1 and the second end of the vehicle body 1 are both configured to be capable of being turned in a direction away from the traveling frame 2, the locking connection mechanism further includes a locking second connection mechanism 29 for locking the first end of the vehicle body 1 and the first end of the frame connector, after the locking state of the locking second connection mechanism 29 on the first end of the vehicle body 1 and the first end of the frame connector is released, a turning rotation center of the first end of the vehicle body is formed by adaptive connection of the second end of the vehicle body 1, the second end of the frame connector and the locking first connection mechanism 26 in the locking state, and the first end of the vehicle body 1 can be turned in a direction away from the traveling frame 2 around the turning rotation center of the first end of the vehicle body.

As can be seen from the above description, in a specific implementation, when it is necessary to tilt the vehicle body 1 on the traveling frame 2, the second end of the vehicle body 1 may be driven to tilt in a direction away from the traveling frame 2, or the first end of the vehicle body 1 may be driven to tilt in a direction away from the traveling frame 2, that is, both the first end and the second end of the vehicle body have the capability of tilting in a direction away from the traveling frame 2; however, in operation, the vehicle body 1 is tilted on the vehicle frame 2 in such a manner that it is moved away from the vehicle frame 2 only by the first end of the vehicle body or only by the second end of the vehicle body.

In order to adapt to the situation that both the first end and the second end of the vehicle body are tilted in the direction away from the traveling frame 2, the lock connection mechanism further includes the lock second connection mechanism 29, compared with the above-mentioned implementation that only the second end of the vehicle body is tilted in the direction away from the traveling frame 2, that is, in this implementation, the lock connection mechanism needs to include both the lock first connection mechanism 26 and the lock second connection mechanism 29, and the specific case of locking the first connection mechanism 26 can refer to the above description. For the locking second connecting mechanism 29, the first end of the vehicle body 1 and the first end of the connecting body of the frame connecting body can be locked mutually by the locking second connecting mechanism 29; of course, the second coupling mechanism 29 can be unlocked from locking the first end of the vehicle body 1 and the first end of the frame coupling body.

In specific implementation, after the locking state of the first end of the vehicle body 1 and the first end of the connecting body of the frame connecting body by the second connecting mechanism 29 is released, the first end of the vehicle body 1 can be turned around the first end of the vehicle body to a direction away from the traveling frame 2 by the adaptive connection of the second end of the vehicle body 1, the second end of the connecting body of the frame connecting body and the first connecting mechanism 26 in the locking state to form a first end turning and rotating center of the vehicle body.

Therefore, when the first end and the second end of the vehicle body both have the capability of tilting in the direction away from the traveling crane frame 2, two tilting rotation centers are required to be configured at the same time in order to realize different tilting requirements, and the two tilting rotation centers are respectively: the first end of the vehicle body overturns the center of rotation and the second end of the vehicle body overturns the center of rotation. When the first end of the vehicle body needs to be turned and inclined in the direction far away from the traveling frame 2, the first end of the vehicle body rotates around the turning and rotating center of the first end of the vehicle body; when the second end of the vehicle body needs to be turned and inclined in the direction away from the traveling frame 2, the second end of the vehicle body rotates around the turning and rotating center of the second end of the vehicle body.

In order to form a vehicle body first end turning rotation center and a vehicle body second end turning rotation center, the invention also comprises a vehicle body connecting body, wherein the vehicle body second end of the vehicle body 1 is hinged with the second end of the vehicle body connecting body, and the first end of the vehicle body connecting body is hinged with the first end of the connecting body of the vehicle frame connecting body, so that the vehicle body second end turning rotation center is formed by the hinged connection part of the first end of the vehicle body connecting body and the first end of the connecting body of the vehicle frame connecting body;

when the second end of the vehicle body connecting body and the second end of the connecting body of the frame connecting body are mutually locked through the locking first connecting mechanism 26 in a locking state, a first vehicle body end turning and rotating center is formed by a hinged connecting part of the second vehicle body end of the vehicle body 1 and the second vehicle body connecting body end;

when passing through the turning area of the sorting track 23, the vehicle body 1 is engaged with the turning area of the sorting track 23, so that the locking first connecting mechanism 26 is kept in the unlocking state during passing through the turning area of the sorting track 23, and the locking second connecting mechanism 29 is kept in the locking state; alternatively, the second link mechanism 29 may be kept in the unlocked state while the first link mechanism 26 is kept in the locked state during the passage through the turning area of the sorting rail 23.

As shown in fig. 7, 8, 9, 11 and 12, a concrete embodiment of the vehicle body connecting body is shown, and as for the frame connecting body, the concrete embodiment of the frame connecting body can refer to the above description, as in the case of the frame connecting body shown in fig. 1 to 3. As can be seen from the figure, the vehicle body connecting body comprises two movable connecting plates 30, namely, the two movable connecting plates 30 are respectively connected with the two frame connecting plates 9 in a one-to-one correspondence manner. Specifically, the first end of the movable connecting plate 30 is hinged to the first end of the frame connecting plate 9, and as can be seen from the above description, the first end of the frame connecting plate 9 is provided with the rotating connecting bearing 17, and the first end of the movable connecting plate 30 is matched with the rotating connecting bearing 17 through the first end connecting shaft of the movable connecting plate, so that the movable connecting plate 30 is hinged to the first end of the frame connecting plate 9, and therefore the overturning center of rotation of the second end of the vehicle body is formed through the hinged connection part between the first end of the movable connecting plate 30 and the first end of the frame connecting plate 9.

The second end of the movable connecting plate 30 is correspondingly hinged to the body connecting lug 10 of the vehicle body 1, that is, in fig. 7, 8, 9, 11 and 12, two body connecting lugs 10 are provided at the second end of the vehicle body 1, and the body connecting lugs 10 are hinged to the second end of the movable connecting plate 30 through the body connecting lug connecting shaft 27, compared with the embodiment in fig. 1. In order to be capable of being locked and matched with the second end of the frame connecting plate 9, a movable connecting plate hole 28 is formed in the movable connecting plate 30, the movable connecting plate hole 28 penetrates through the movable connecting plate 30, and the matching form of the movable connecting plate hole 28 and the frame connecting plate hole 12 in the frame connecting plate 9 is consistent with the specific matching form of the vehicle body connecting lug hole 11 and the frame connecting plate hole 12.

In a specific implementation, the locking first connecting mechanism 26 and the locking second connecting mechanism 29 are located on the same side, that is, the same frame connecting plate 9 is assembled and connected, specifically, the locking first connecting mechanism and the locking second connecting mechanism are connected in a matched manner with the frame connecting plate 9 far away from the running wheel seat 16. Through the cooperation of the locking first connecting mechanism 26, the movable connecting plate hole 28 and the frame connecting plate hole 12, the movable connecting plate 30 and the corresponding adjacent frame connecting plate 9 can be locked with each other, and after the locking, the second end of the vehicle body 1 cannot be driven to turn in the direction away from the traveling frame 2. Because the vehicle body connecting lug 10 at the second end of the vehicle body is hinged with the second end of the movable connecting plate 30, a vehicle body first end overturning and rotating center is formed by the hinged connection part of the vehicle body connecting lug 10 and the second end of the movable connecting plate 30, namely, when the first end of the vehicle body is driven to overturn towards the direction far away from the traveling frame 2, the second end of the vehicle body 1 rotates around the vehicle body first end overturning and rotating center.

During specific implementation, when the vehicle body 1 is horizontally distributed on the traveling frame 2, the second end of the movable connecting plate 30 and the second end of the frame connecting plate 9 are mutually locked through the first locking connecting mechanism 26, and meanwhile, the first end of the vehicle body 1 and the frame connecting plate 9 are mutually locked through the second locking connecting mechanism 29, so that the vehicle body 1 is prevented from falling off when the vehicle body 1 travels in a straight area of the sorting track 23 and is overturned and inclined to cause articles to be sorted.

When passing through the turning area of the sorting track 23, the vehicle body 1 is engaged with the turning area of the sorting track 23, so that the locking first connecting mechanism 26 is kept in the unlocking state during passing through the turning area of the sorting track 23, and the locking second connecting mechanism 29 is kept in the locking state; alternatively, the second link mechanism 29 is locked to be kept in the unlocked state during passing through the turning area of the sorting rail 23 while the first link mechanism 26 is locked to be kept in the locked state. Therefore, when passing through the turning area of the sorting rail 23, the lock first link mechanism 26 or the lock second link mechanism 29 is in the locked state to be able to turn the vehicle body first end or the vehicle body second end in the direction away from the traveling carriage 2.

As shown in fig. 7, 8 and 10, a specific implementation of the locking first connecting mechanism 26 is shown, specifically, the locking first connecting mechanism 26 includes a locking connecting seat 39 for fixedly connecting with the corresponding frame connecting plate 9, a locking plate 38 adapted to the locking connecting seat 39, and a return elastic mechanism for providing a return elastic force, wherein a first end of the locking plate 38 is hinged to the locking connecting seat 39 through a locking connecting plate shaft 44, an unlocking second roller 37 is provided at a second end of the locking plate 38, the unlocking second roller 37 is assembled to the second end of the locking plate 38 through an unlocking second roller shaft, and the unlocking second roller 37 can rotate at the second end of the locking plate 38.

A first bolt 46 and a lock plate cushion 43 are arranged on one side, close to the corresponding frame connecting plate 9, of the lock plate 38, and when the lock plate is locked, the lock plate cushion 43 is in contact fit with the frame connecting plate 9, so that the buffer purpose is achieved. The elastic mechanism that resets includes extension spring 40 that resets, the one end of extension spring 40 that resets is connected with the lower extreme of the first connecting rod 41 of extension spring, and the other end of extension spring 40 that resets is connected with the lower extreme of extension spring second connecting rod 42, and the upper end of the first connecting rod 41 of extension spring is connected with the downside fixed surface of locking plate 38, and the upper end of extension spring second connecting rod 42 is connected with the downside fixed surface of locking connecting seat 39.

When the first latch 46 passes through the movable connecting plate hole 28 on the movable connecting plate 30 and then extends into the frame connecting plate hole 12, the locking action of the first latch 46 is utilized to realize the locking between the movable connecting plate 30 and the frame connecting plate 9. At this time, the second end of the vehicle body 1 cannot be driven to turn in a direction away from the traveling frame 2. When the movable connecting plate 30 is driven to move outward by unlocking the second roller 37 until the first lock tongue 46 is withdrawn from the movable connecting plate hole 28 and the frame connecting plate hole 12, the locking state of the movable connecting plate 30 and the frame connecting plate 9, namely the locking state of the first connecting mechanism 26, is released.

When the locking first connecting mechanism 26 is in the unlocking state, the reset tension spring 40 is in a tensioned state, and when the unlocking driving force loaded by the unlocking second roller 37 disappears, the reset tension spring 40 will pull the locking plate 38 to approach the frame connecting plate 9 again, and then the first locking tongue 46 will pass through the movable connecting plate hole 28 again and extend into the frame connecting plate hole 12, so as to lock the second end of the movable connecting plate 30 and the second end of the frame connecting plate 9 again. Of course, it is desirable to ensure that the kinematic plate hole 28 is in positive alignment with the frame attachment plate hole 12 when the first latch tongue 46 extends into the frame attachment plate hole 12 after passing through the kinematic plate hole 28 again.

In specific implementation, when the second end of the vehicle body 1 corresponds to the outer rail body of the turning area of the sorting rail 23, the second roller 37 is unlocked to drive the movable connecting plate 30 to move outwards, and the mutual locking state between the second end of the movable connecting plate 30 and the second end of the frame connecting plate 9 is released, so that the second end of the vehicle body 1 can be turned away from the traveling frame 2. The automobile body second end of automobile body 1 is to keeping away from the direction upset of driving frame 2 and through the regional back of turning, utilizes the gravity of automobile body 1 automobile body second end for the second end whereabouts of automobile body second end of automobile body 1 is close to the second end of frame attach board 9, behind the spacing bradyseism body 14 of automobile body contact cooperation to the side of automobile body 1, so that swing joint diaphragm orifice 28 can just aim at with frame attach diaphragm orifice 12.

As for the sorting cart shown in fig. 1 and fig. 2, as can be seen from the above description, the locking first connecting mechanism 26 may adopt the same form as that in fig. 10, but when locking, the vehicle body connecting lug 10 and the vehicle body connecting lug hole 11 penetrating through the vehicle body connecting lug 10 are matched with the first locking tongue 46, and other situations are the same and will not be described herein again.

As shown in fig. 7, 8 and 9, a specific implementation of the locking second connecting mechanism 29 is shown, the locking second connecting mechanism 29 locks the first end of the vehicle body 1, and the locking second connecting mechanism 29 may specifically adopt the same locking fit form as the locking first connecting mechanism 26.

In order to meet the requirements of space layout and the like, in the embodiment of the present invention, the second locking connecting mechanism 29 includes a fixed locking seat, a frame locking connecting plate 33, and a body locking hook 32 disposed at the first end of the body of the vehicle 1, where the fixed locking seat is fixed at the first end of the frame connecting plate 9, the fixed locking seat is provided with a first unlocking roller 35, a second locking tongue 36, and a tongue resetting elastic mechanism, and the situation of the first unlocking roller 35 and the second locking tongue 36 during specific locking can be referred to the specific situation of the first locking connecting mechanism 26 for unlocking the second unlocking roller 37 and the first locking tongue 46, and the specific role of the tongue resetting elastic mechanism is consistent with the situation of the resetting elastic mechanism, and it can be referred to the above description, and details are not repeated here.

The frame locking connection piece 33 is relatively fixed to a first end of the frame connection plate 9, for example, to a first end connection shaft of the movable connection plate. The frame locking connecting piece groove 34 is arranged on the frame locking connecting piece 33, and the frame locking connecting piece groove 34 is an opening groove at the outer side of the frame locking connecting piece 33. Similar to the operation of the locking first connecting mechanism 26, the second locking tongue 36 is disposed in the frame locking connecting piece groove 34 and the vehicle body locking hook 32, so as to lock the first end of the vehicle body 1 with the first end of the frame connecting plate 9. When the vehicle passes through the turning area of the sorting rail 23, the unlocking first roller 35 pushes the second latch tongue 36 to rotate, and when the second latch tongue 36 is withdrawn from the frame locking connecting piece groove 34 and the vehicle body locking hook 32, the locking state of the second connecting mechanism 29 is released. After the unlocking acting force applied by unlocking the first roller 35 disappears, under the action of the bolt resetting elastic mechanism, the second bolt 36 can be placed in the frame locking connecting sheet groove 34 and the frame locking hook 32 again, so that the first end of the frame of the vehicle body 1 and the corresponding frame connecting plate 9 can be locked with each other, and the process of specifically unlocking and recovering the locked state can refer to the working process description of the first locking connecting mechanism 26, which is not described herein again.
