The embodiment of the application provides a sorting dolly, track and letter sorting equipment turn round. The following are detailed below.

Firstly, the embodiment of the application provides a sorting trolley, which comprises a support frame, wherein the support frame comprises a cross beam, two opposite ends of the cross beam are respectively provided with a connecting structure, the connecting structure is rotatably connected with an installation seat, the rotating axis of the installation seat is consistent with the direction from the front end to the rear end of the sorting trolley, and a travelling wheel is rotatably arranged on the installation seat; at least one connection structure includes the guide part that sets up at the crossbeam tip, and with guide part sliding connection's slider, the guide part extends along the length direction of crossbeam, slider and mount pad rotate and be connected.

Fig. 1 is a schematic structural view of a sorting trolley and a turning track in cooperation, according to an embodiment of the present application. As shown in fig. 1, the sorting cart 200 according to the embodiment of the present invention further includes a supporting frame 210, the supporting frame 210 includes a cross beam 211, the connecting structures 212 are respectively disposed at two opposite ends of the cross beam 211, a mounting base 215 is rotatably connected to the connecting structures 212, a rotation axis of the mounting base 215 extends along an inside and outside direction (a direction perpendicular to both the up-down direction and the left-right direction in the drawing) of the sorting cart 200, and a traveling wheel 217 is rotatably mounted on the mounting base 215, a rotation axis of the traveling wheel 217 is aligned with a length direction of the cross beam 211, so that the sorting cart 200 is supported on two guide rails of the rail mechanism by the traveling wheels 217 at two ends of the cross beam 211 and rolls along the two guide rails. The rotation axes of the walking wheels 217 are consistent along the length direction of the cross beam 211, so that the rotation axes of the walking wheels 217 are parallel to the length direction of the cross beam 211, and a small acute angle can be formed between the rotation axes of the walking wheels 217 and the length direction of the cross beam 211.

In some embodiments, as shown in fig. 1 and 2, the at least one connecting structure 212 includes a guiding portion 213 disposed at an end of the cross beam 211, and a sliding member 214 slidably connected to the guiding portion 213, wherein the guiding portion 213 extends along a length direction of the cross beam 211, and the sliding member 214 is rotatably connected to the mounting base 215.

It will be appreciated that the height of the inner rail 120 of the corner rail 100 is less than the height of the outer rail 130, and that as the sorting cart 200 travels from the horizontal track to the corner rail 100, there is a difference in height between the road wheels 217 of the sorting cart 200 supported on the inner rail 120 and the road wheels 217 supported on the outer rail 130, and the relative position between the two road wheels 217 needs to be changed accordingly.

Specifically, as shown in fig. 1, the height of the left outer rail 130 is greater than the height of the right inner rail 120, and therefore, the distance between the top of the outer rail 130 and the top of the inner rail 120 is increased. In order to stably support the two traveling wheels 217 on the outer and inner rails 130 and 120 after the sorting cart 200 travels from the horizontal rail to the corner rail 100, it is necessary to maintain the horizontal rotation axes of the left and right traveling wheels 217, and simultaneously, the height of the left traveling wheel 217 is greater than that of the right traveling wheel 217, and further, it is necessary to increase the distance between the left and right traveling wheels 217.

In the embodiment of the application, by rotating the mounting seats 215 relative to the connecting structures 212, when the sorting trolley 200 moves from the horizontal rail to the turning rail 100, the left end of the cross beam 211 can rotate upwards, and the two mounting seats 215 can rotate at a certain angle relative to the two connecting structures 212 at the two ends of the cross beam 211, so that the rotating axes of the walking wheels 217 on the two mounting seats 215 are still kept horizontal, and meanwhile, the two walking wheels 217 can generate a height difference (the height of the walking wheel 217 on the left side is greater than that of the walking wheel 217 on the right side).

Meanwhile, by sliding the sliding member 214 of the at least one connecting structure 212 relative to the guide portion 213, the mounting seat 215 rotatably connected to the sliding member 214 and the traveling wheels 217 mounted on the mounting seat 215 are also slid together, so that the distance between the traveling wheels 217 at both ends of the cross beam 211 is increased, so that the traveling wheels 217 at both ends of the cross beam 211 can be stably supported on the inner and outer guide rails 120 and 130 of the corner rail 100 and can stably run on the inner and outer guide rails 120 and 130.

Therefore, the sorting trolley 200 provided by the embodiment of the present application can smoothly move from the horizontal rail to the turning rail 100 with the inconsistent height of the inner rail 120 and the outer rail 130 during the operation on the rail mechanism.

Of course, the sorting cart 200 provided in the embodiment of the present application can also be smoothly moved from the turning rail 100 of the rail mechanism to the horizontal rail, as shown in fig. 2, only the mounting seat 215 needs to be rotated reversely relative to the connecting structure 212, and the sliding member 214 of at least one connecting structure 212 needs to be slid reversely, which is not described herein again.

In some embodiments, the connecting structure 212 at two opposite ends of the cross beam 211 may include a guide portion 213 and a sliding member 214, that is, two ends of the cross beam 211 are extended and contracted to change the distance between the traveling wheels 217 at two ends of the cross beam 211, so that the sorting cart 200 can be maintained in a centered state during the operation on the track mechanism, thereby improving the operation stability of the sorting cart 200.

In other embodiments, the connecting structure 212 at one end of the cross beam 211 may include the guiding portion 213 and the sliding member 214, and the connecting structure 212 at the other end of the cross beam 211 does not include the guiding portion 213 and the sliding member 214, but is directly fixed with the cross beam 211, that is, only one end of the cross beam 211 can be extended and retracted. The distance between the travelling wheels 217 at the two ends of the cross beam 211 can also be changed by extending and retracting one end of the cross beam 211.

It will be appreciated that if the connecting structure 212 of only one end of the cross member 211 includes the guide portion 213 and the sliding member 214, that is, if only one end of the cross member 211 can be extended or retracted, after the sorting cart 200 moves from the horizontal rail to the turning rail 100, the sorting cart 200 may be shifted toward the inner rail 120 or the outer rail 130 by a distance along with the extension of one end of the cross member 211, and thus may not be in the centered position.

If the connecting structure 212 at both ends of the cross beam 211 includes the guide portion 213 and the sliding member 214, that is, both ends of the cross beam 211 can be extended and retracted, when the sorting cart 200 moves from the horizontal rail to the turning rail 100, both ends of the cross beam 211 are extended, so that the sorting cart 200 does not deviate a large distance toward the inner guide rail 120 or the outer guide rail 130, and especially, when the extended lengths of both ends of the cross beam 211 are equal, the sorting cart 200 can be located at the middle position between the inner guide rail 120 and the outer guide rail 130.

In some embodiments, as shown in fig. 1 and 2, the guiding portion 213 includes a sliding slot 2131 extending along the length direction of the cross beam 211, the sliding member 214 has a first end and a second end opposite to each other, the first end of the sliding member 214 is slidably installed in the sliding slot 2131, and the second end of the sliding member 214 is rotatably connected to the mounting seat 215. By inserting the first end of the slider 214 into the slide groove 2131 of the guide portion 213 to slidably couple the slider 214 and the guide portion 213, the sliding between the guide portion 213 and the slider 214 can be further stabilized.

In other embodiments, the guiding portion 213 may be a guide rail extending along the length direction of the cross beam 211, and the sliding member 214 may be a sliding block engaged with the guide rail, and the mounting seat 215 is hinged to the sliding block, so that the mounting seat 215 can rotate and slide relative to the cross beam 211.

In some embodiments, as shown in fig. 1 to 3, the guide portion 213 further includes an elastic member 216, and one end of the elastic member 216 is connected to the sliding member 214 to apply an elastic force to the sliding member 214, the elastic force being used to slide the sliding member 214 in a direction from the middle of the cross beam 211 to the corresponding end of the cross beam 211.

Wherein, the corresponding end of the cross beam 211 refers to the end of the cross beam 211 where the at least one connecting structure 212 is installed. When the connecting structure 212 of the left end of the cross beam 211 includes the guide portion 213 and the slider 214, the corresponding end of the cross beam 211 is the left end of the cross beam 211; when the connecting structure 212 of the right end of the cross beam 211 includes the guide portion 213 and the slider 214, the corresponding end of the cross beam 211 is the right end of the cross beam 211.

It can be understood that, by applying an elastic force to the sliding member 214 through the elastic member 216 for sliding the sliding member 214 in the direction from the middle of the cross beam 211 to the corresponding end of the cross beam 211, when the sorting cart 200 moves from the horizontal rail to the corner rail 100, the sliding member 214 automatically slides toward the end of the cross beam 211 by the elastic member 216 to increase the total length of the cross beam 211, thereby increasing the distance between the traveling wheels 217 at both ends of the cross beam 211.

The elastic force applied by the elastic member 216 to the slider 214 may be a tensile force or a pushing force, and may be determined according to the structure and the mounting position of the elastic member 216. In some embodiments, the elastic member 216 is located on one side of the slider 214 in the corresponding end-to-middle direction of the cross beam 211, and the elastic force exerted by the elastic member 216 on the slider 214 is a pushing force.

In some embodiments, an elastic member 216 is installed in the sliding groove 2131 and is opposite to an end surface of the first end of the sliding member 214, wherein one end of the elastic member 216 abuts against an inner wall of the sliding groove 2131, and the other end of the elastic member 216 abuts against the first end of the sliding member 214 to apply a pushing force to the sliding member 214, and the pushing force is used for sliding the sliding member 214 toward the outside of the sliding groove 2131. By installing the elastic member 216 in the slide groove 2131, the guide portion 213 and the slider 214 can protect the elastic member 216, and the elastic member 216 can be more easily installed, and the connection between the elastic member 216 and the guide portion 213 and the slider 214 can be more stable.

The end surface of the first end of the sliding element 214 is provided with a receiving groove 2141, one end of the elastic element 216 abuts against the inner wall of the sliding groove 2131, and the other end of the elastic element 216 is inserted into the receiving groove 2141 and abuts against the bottom surface of the receiving groove 2141, so that the elastic force applied by the elastic element 216 to the sliding element 214 is more stable. Meanwhile, under the condition that the sizes of the sliding piece 214 and the sliding groove 2131 are not changed, the length of the elastic piece 216 can be increased, and the elastic effect of the elastic piece 216 is better.

In some embodiments, as shown in fig. 1 and fig. 2, the two mounting seats 215 at the two ends of the cross beam 211 are further respectively mounted with guide wheels 218, and the two guide wheels 218 at the two ends of the cross beam 211 are located between the two road wheels 218 at the two ends of the cross beam 211, and the rotation axes of the guide wheels 218 extend in the up-down direction. Accordingly, the guide wheels 218 located at both ends of the cross beam 211 can be respectively abutted against the first guide plate 136 of the outer rail 130 and the second guide plate 122 of the inner rail 120 to restrict the sorting cart 200 from moving in the width direction of the turning rail 100 (the arrangement direction of the inner rail 120 and the outer rail 130), and particularly, when the guide portion 213 further includes the elastic member 216, the elastic member 216 can always keep the guide wheels 218 located at both ends of the cross beam 211 in abutment against the first guide plate 136 of the outer rail 130 and the second guide plate 122 of the inner rail 120, respectively, thereby improving the running stability of the sorting cart 200.

In other embodiments, a guide groove for the traveling wheels 217 may be provided on the inner rail 120 and the outer rail 130, and the guide groove may restrict the traveling wheels 217 from moving in the direction of the rotation axis of the traveling wheels 217. When the sorting trolley 200 moves from the horizontal rail to the turning rail 100, the inner side walls of the guide grooves exert a thrust force on the side surfaces of the traveling wheels 217, so that the traveling wheels 217 pull the sliding members 214 to slide along the direction from the middle of the cross beam 211 to the corresponding end of the cross beam 211 through the mounting seats 215, thereby increasing the overall length of the cross beam 211.

In some embodiments, as shown in fig. 3, the support frame 210 further comprises a support beam 219, one end of the support beam 219 is connected to the middle of the cross beam 211 and is disposed at an angle to the cross beam 211, and a transmission assembly 222 is mounted on the support beam 219. The goods on the sorting cart 200 are placed on the transfer assembly 222, and after the sorting cart 200 is moved to the corresponding cell position on the rail mechanism, the transfer assembly 222 is controlled to operate to transfer the goods thereon into the corresponding cell.

Specifically, one end of the supporting beam 219 is connected with the middle of the cross beam 211 to form a T-shaped supporting frame 210, the transmission assembly 222 includes opposite mounting plates 223, the two mounting plates 223 are respectively supported at opposite ends of the supporting beam 219, a driving wheel (not shown in the figure) and a driven wheel (not shown in the figure) are rotatably connected between the two mounting plates 223, the driving wheel and the driven wheel are sequentially distributed along the length direction of the cross beam 211, the rotation axes of the driving wheel and the driven wheel extend along the length direction of the supporting beam 219, the driving wheel and the driven wheel are connected through a transmission belt 224, and the transmission belt 224 can transmit along the length direction of the cross beam 211 by controlling the rotation of the.

In other embodiments, the conveying assembly 222 may be a conveying track, or a conveying structure formed by a plurality of conveying rollers arranged in sequence along the length direction of the cross beam 211, and is not limited herein.

In some embodiments, as shown in fig. 3, the supporting frame 210 is provided with a joint mount 220 and a universal joint bearing 221 at both ends along the front and rear of the sorting cart 200, the joint mount 220 on the supporting frame 210 is used for connecting with the universal joint bearing 221 on the front sorting cart 200, and the universal joint bearing 221 on the supporting frame 210 is used for connecting with the joint mount 220 of the rear sorting cart 200, so as to connect a plurality of sorting carts 200 in series on the track mechanism. At this time, the supporting frame 210 of each sorting trolley 200 only needs to be provided with one cross beam 211, so that the structure of the sorting trolley 200 is simplified, and the cost of the sorting trolley 200 is reduced.

The joint mounting base 220 is disposed on a side of the cross beam 211 away from the support beam 219, and the universal joint bearing 221 is disposed on an end of the support beam 219 away from the cross beam 211. Alternatively, the joint mount 220 may be disposed at an end of the support beam 219 away from the cross beam 211, and the universal joint bearing 221 may be disposed at a side of the cross beam 211 away from the support beam 219.

The present embodiment also provides a corner rail 100, as shown in fig. 4, the corner rail 100 includes a rail bracket 110, and an inner rail 120 and an outer rail 130 which are installed on the rail bracket 110 and are arranged in a curved manner, wherein the inner rail 120 and the outer rail 130 are arranged in parallel, and the height of the inner rail 120 is less than that of the outer rail 130. When the sorting cart 200 travels on the curve track 100, the traveling wheels 217 of both sides of the sorting cart 200 are supported on the inner and outer rails 120 and 130, respectively, and curve along the curved directions of the inner and outer rails 120 and 130.

Because the height of inner rail 120 is less than the height of outer rail 130, consequently, the height of walking wheel 217 of walking on inner rail 120 also can be less than the height of walking wheel 217 of walking on outer rail 130, thereby lead to sorting dolly 200 along the direction downward sloping of outer rail 130 to inner rail 120, after the goods on sorting dolly 200 received centrifugal force, can increase the pressure between goods and the sorting dolly 200, and then increase the frictional force between goods and the sorting dolly 200, in order to avoid the goods on sorting dolly 200 to produce under the effect of centrifugal force and slide or get rid of and fly.

In some embodiments, the outer rail 130 includes a first lifting structure 131 mounted on the rail bracket 110, and a first rail 134 mounted on the first lifting structure 131. The first lifting structure 131 can control the first guide rail 134 to lift, so as to change the height of the first guide rail 134, and further change the height difference between the outer guide rail 130 and the inner guide rail 120, and the inclination angle of the sorting trolley 200 when the sorting trolley travels on the turning track 100 is changed accordingly.

When the running speed of the sorting trolley 200 on the turning track 100 is increased, the first lifting structure 131 can control the first guide rail 134 to ascend so as to increase the height of the first guide rail 134, and further increase the height difference between the outer guide rail 130 and the inner guide rail 120, so that the inclination angle of the sorting trolley 200 when walking on the turning track 100 is larger. Since the diameter of the curve track 100 is preset, when the speed of the sorting cart 200 traveling on the curve track 100 is determined, the centrifugal force applied to the goods on the sorting cart 200 is not changed and is directed to the center of the curve track 100.

After the sorting dolly 200 inclines the bigger angle when walking on the track 100 that turns round, the holding power that sorting dolly 200 applyed the goods has a centre of a circle component towards the track 100 that turns round in the horizontal direction, under the combined action of the frictional force between this component and sorting dolly 200 and the goods, can prevent effectively that the goods on the sorting dolly 200 from sliding or get rid of under the effect of centrifugal force and fly.

When the running speed of the sorting trolley 200 on the turning track 100 is reduced, the first guide rail 134 can be controlled to descend through the first lifting structure 131, so that the height of the first guide rail 134 is reduced, the height difference between the outer guide rail 130 and the inner guide rail 120 is further reduced, the inclined angle of the sorting trolley 200 on the turning track 100 is smaller, the phenomenon that the inclined angle of the sorting trolley 200 is too large, and the goods on the sorting trolley 200 slide along the inclined direction of the sorting trolley 200 is avoided.

From this, according to the functioning speed of letter sorting dolly 200 on track 100 turns round, can adjust the difference in height of outer guide rail 130 and interior guide rail 120 through first elevation structure 131, and then adjust the inclination of letter sorting dolly 200, avoid the goods on the letter sorting dolly 200 to slide or get rid of and fly, improved the application scope on track 100 turns round.

In other embodiments, the inner rail 120 includes a second lifting structure mounted on the rail bracket 110, and a second rail mounted on the second lifting structure. The second lifting structure can control the second guide rail to lift, so as to change the height of the second guide rail, and further change the height difference between the outer guide rail 130 and the inner guide rail 120, and the inclination angle of the sorting trolley 200 when walking on the turning track 100 is changed together with the change.

When the running speed of the sorting trolley 200 on the turning track 100 is increased, the second guide rail can be controlled to descend through the second lifting structure, so that the height of the second guide rail is reduced, the height difference between the outer guide rail 130 and the inner guide rail 120 is increased, the inclined angle of the sorting trolley 200 on the turning track 100 is larger, the friction force between the goods and the sorting trolley 200 is improved, and the goods on the sorting trolley 200 cannot slide or get rid of and fly.

When the running speed of the sorting trolley 200 on the turning track 100 is reduced, the second guide rail can be controlled to ascend through the second lifting structure, so that the height of the second guide rail is increased, the height difference between the outer guide rail 130 and the inner guide rail 120 is reduced, the inclined angle of the sorting trolley 200 on the turning track 100 is smaller, the phenomenon that the inclined angle of the sorting trolley 200 is too large is avoided, and the goods on the sorting trolley 200 slide along the inclined direction of the sorting trolley 200 is caused.

From this, according to the functioning speed of letter sorting dolly 200 on track 100 turns round, can adjust the difference in height of outer guide rail 130 and inner rail 120 through second elevation structure, and then adjust letter sorting dolly 200's inclination, avoid the goods on letter sorting dolly 200 to slide or get rid of and fly, improved the application scope on track 100 turns round.
