Detailed Description

As shown in fig. 1 and 2, the present invention discloses a handling apparatus 100 with a two-section retractable pallet, which includes a frame 110, and a driving wheel 111 disposed on the frame 110. The frame 110 includes two end walls 112 at two ends, two upper connecting beams 114 connecting upper corners of the two end walls 112, and a lower beam 115 located at lower corners of the end walls and parallel to the upper connecting beams 114. The lower beam 115 is extended outward with a guide wheel 116, and when the automated walking transfer apparatus 100 moves along the ground rail 201 under the limit of the ground rail 201, the guide wheel 116 abuts against the inner side of the ground rail 201 to achieve a guiding function.

As shown in fig. 3 to 11, the present invention is an embodiment of a two-segment telescopic pallet used in the present invention. The middle of the frame 110 is provided with a telescopic supporting plate 150, and the telescopic driving device and the climbing driving device are respectively located at two sides of the telescopic supporting plate 150. The telescopic driving device and the climbing driving device do not interfere with each other in the frame 110. The telescopic blade 150 includes a frame 151, a middle blade 152 provided on the frame 151, and an upper blade 153 provided on the middle blade 152. At least two driving sprockets and a driving chain 154 rotating around the driving sprockets are disposed on one side of the frame 151, and the driving chain 154 includes a reciprocating section 1541 located at the top of the entire driving chain 154 and extending laterally. A rack 155 engaged with the reciprocating section 1541 is arranged below one side surface of the middle supporting plate 152, and when the transmission chain 154 rotates along with the transmission chain wheel, the rack 155 is driven by the transmission chain 154 to reciprocate; so that the middle support plate 152 can reciprocate with the rack gear 155. I.e., the center pallets 152 can extend toward the shelf cells 202 on either side of the automated walking conveyor 100 when in use. Specifically, the driving sprockets on the side of the frame 151 include a driving sprocket 156 and two driven sprockets 157. The two driven sprockets 157 are disposed at the same height on the sides of the frame 151, and the driving sprocket 156 is disposed at an intermediate position below the two driven sprockets 157. The frame 151 is also provided on its side with a laterally extending chain bracket 158 located between the two driven sprockets 157. The upper surface of the chain bracket 158 is higher than the uppermost end of the driven sprocket 157, and when the reciprocating section 1541 of the driving chain is engaged with the rack 155, the chain bracket 158 abuts against the lower side of the reciprocating section 1541. The chain bracket 158 functions to lift the reciprocating section 1541 relative to the two driven sprockets 157 so that the rack 155 is always moved higher than the driven sprockets 157 without interfering with the driven sprockets 157 to hinder the movement of the rack 155.

As shown in fig. 5 to 9, the two outer side surfaces of the middle supporting plate 152 are provided with outer roller rails 1521 which are inwardly concave; the inner side surfaces are provided with inner roller rails 1522 which are inwards concave, and the inner roller rails 1522 and the outer roller rails 1521 extend backwards and in the same direction. A row of first rollers 1511 transversely extending is disposed at the upper ends of the two side surfaces of the frame 151, the first rollers 1511 are located in the inner roller rails 1522, and the middle supporting plate 152 freely extends or retracts relative to the frame 151 through the cooperation of the first rollers 1511 and the inner roller rails 1522. Two sides of the upper supporting plate 153 are bent downwards to form upper folding plates 1531. The two upper flaps 1531 each have a second roller 1532 on the inner side thereof, and the second roller 1532 is carried on the outer roller track 1521 and slides along the outer roller track 1521. An upper cord holder 161 is installed at one end of the lower surface of the upper flap 1531, and a lower cord holder 162 is installed above the frame 151 at the same end as the end where the upper cord holder 161 is installed. That is, if the frame 151 and the upper flap 1531 have one end as a front end and the other end and a rear end, and the upper cord holder 161 is provided at the front end of the upper flap 1531, the lower cord holder 162 engaged with the upper cord holder 161 is located at the front end of the frame 151 (here, located at the "same end" and limited to the outermost edge portions of the frame 151 and the upper flap 1531, and a position close to the edge but not yet reaching the edge may be pushed or pulled by the cord as described below). And the middle support plate 152 has a pulley groove at an end opposite to the upper and

lower rope holders

161 and 162, and a follower pulley 163 is installed in the pulley groove. A rope 164 is connected between the upper rope holder 161 and the lower rope holder 162, one end of the rope 164 is fixed to the upper rope holder 161, and the other end of the rope 164 is wound around a follower pulley 163, extends from above the middle support plate 152 to below the middle support plate 152, and is finally fixed to the lower rope holder 162. The structure of the upper rope fixer 161, the follower pulley 163 and the lower rope fixer 162 connected by the rope 164 can drive the upper supporting plate 153 to further extend outwards relative to the middle supporting plate 152 when the middle supporting plate 152 extends to one side of the frame 151, so that the combined extension length of the upper supporting plate 153 and the middle supporting plate 152 is further lengthened, which is beneficial to the picking and placing operation of deep goods in the shelf unit lattice 202. That is, in this embodiment, the upper cable holder 161, the follower pulley 163, and the lower cable holder 162 are connected by the cable 164 to serve as a driver for further extending the upper plate 153 with respect to the middle plate 152. Specifically, since the lengths of the ropes 164 are constant and the lower rope holder 162 is always kept at a fixed position, when the middle support plate 152 is extended to one side with respect to the frame 151, the following pulley 163 is also far from the lower rope holder 162 (the distance between the two is long and the rope required between the two is also long), the upper rope holder 161 must be close to the following pulley 163 (the rope required between the two is short), and the upper rope holder 161 drives the entire upper support plate 153 to continue to extend to the side of the middle support plate 152 extended to the middle support plate 152. Further, since it is simultaneously required to enable the upper plate 153 to be retracted as the middle plate 152 is retracted with respect to the frame 151 and the middle plate 152 to be simultaneously extended to the other side following the upper plate 153 when the upper plate 153 is extended to the other side, two sets of the upper rope holder 161, the following pulley 163, and the lower rope holder 162 are required. The positions of the two sets of upper rope holders 161, the follower pulleys 163 and the lower rope holders 162 are opposite, that is, if the upper rope holders 161 and the lower rope holders 162 of one set (the first set) are installed at the front ends of the upper supporting plate 153 and the frame 151, the upper rope holders 161 and the lower rope holders 162 of the other set (the second set) are installed at the rear ends of the upper supporting plate 153 and the frame 151, the positions of the two sets of upper rope holders 161, the follower pulleys 163 and the lower rope holders 162 are symmetrical to each other, and the lengths of the two sets of ropes 164 are also the same. Thus, after the first set of upper cord holder 161, and lower cord holder 162 extend the upper blade 153 to one side, the second set of upper cord holder 161, and lower cord holder 162 enable the upper blade 153 to be retracted as the middle blade 152 is retracted relative to the frame 151. Similarly, the second set of upper cord holder 161, and lower cord holder 162 also enable the upper support plate 153 to extend as the middle support plate 152 extends to the other side, and will not be described in detail herein.

It should be noted here that the two-part retractable pallet provided in the present invention can be arranged on a fixed platform in a shelf as a fixed position goods handling device. Meanwhile, the telescopic supporting plate can also be applied to the conveying equipment which can automatically travel on the goods shelf rail.

As shown in fig. 3, the driving wheels 111 of the automatic transport equipment 100 are also installed on the frame 151, one driving wheel 111 is installed below each of both ends of the frame 151 through a bearing, and a wheel motor unit 1111 (including a motor and a reducer) for driving the driving wheels 111 to rotate is installed inside the frame. The driving of the driving wheel 111 belongs to the prior art in the technical field, and in the invention, the driving wheel 111 is only installed at two ends of the frame 151 to form a modular frame 151 structure. Meanwhile, when the frame 151 is installed in the frame 110, both ends of the frame 151 abut against both sides of the frame 110, and the two driving wheels 111 are located inside both sides of the frame 110, and both ends of the frame 110 are also provided with two auxiliary wheels 113.

Therefore, in the above embodiment, when the automated transport equipment 100 is raised to the designated shelf cell 202 position, the loading and unloading operation of the container can be realized by extending the telescopic bracket (including the upper pallet 153 and the middle pallet 152) to the shelf cell 202 position.

The utility model discloses the method and the way of realizing this technical scheme are many specifically, above only the preferred embodiment of the utility model. It should be noted that, for those skilled in the art, without departing from the principle of the present invention, several improvements and modifications can be made, and these improvements and modifications should also be considered as the protection scope of the present invention. All the components not specified in the present embodiment can be realized by the prior art.
