An intelligent warehouse transport vehicle

Abstract

The present invention relates to the technical field of transport and handling equipment, specifically an intelligent warehouse transport vehicle, including a transport and handling frame, a weighing component, an adjusting support component and a holding component. Four transport moving wheels are symmetrically provided at the lower end of the transport and handling frame, and two conveying rails are horizontally symmetrically provided below the transport and handling frame. By arranging four weighing components between the mounting pallet and the contact pallet, when the items to be transported and handled are placed on the contact pallet, the items can be weighed immediately, so as to judge whether the transport equipment can be used for normal transportation. When the box size of the transported items is large and the internal weight is uneven, the lifting of the contact pallet can be supported by adjusting the adaptability of the support component, so that the side of the box with larger weight or the side extending out of the contact pallet can be tilted and lifted, thereby improving the stability of the items during transportation. In addition, the holding component can mechanically assist in maintaining the support stability of the adjustable support component, which is worry-free and convenient.

According to the usage scenario, the transport and transport frame 1 and the mounting pallet 4 can be fixedly connected by a bracket, or a scissors support mechanism can be provided between the transport and transport frame 1 and the mounting pallet 4, so that the mounting pallet 4 and the contact pallet 5 can be lifted to a certain height for convenient handling and transportation. When in use, the transport and transport frame 1 moves along the conveying rails 3 through the transport and moving wheels 2, and when it moves to the position for conveying objects up and down, objects are placed and removed through loading or unloading clamps.

[0037] A weighing assembly is set to perform weight analysis on the items placed on the contact support plate 5. The weighing assembly is arranged in the installation groove 6. The weighing assembly includes a lifting compensation seat 8 and a lower pressure seat 10, and the upper ends of the four lower pressure seats 10 are respectively connected to the lower end of the contact support plate 5. A first ring 7 is vertically provided on one side of the installation groove 6. The lower end of the lifting compensation seat 8 is vertically movably inserted into the first ring 7. A weighing groove 9 is vertically opened on the upper end of the lifting compensation seat 8. The lower pressure seat 10 is vertically movably inserted into the weighing groove 9. A weighing module 11 is horizontally provided at the lower end of the weighing groove 9. The lower end of the lower pressure seat 10 contacts the upper end of the weighing module 11. A ball head rod 15 is provided on the upper end of the lower pressure seat 10. An adaptor ball groove 14 is opened on one side of the contact support plate 5 close to the lower pressure seat 10. The ball head of the ball head rod 15 is movably inserted into the adaptor ball groove 14. A plurality of connecting grooves 1 are symmetrically opened on four sides of the weighing groove 9. 2. The lower pressing seat 10 is provided with an anti-slip guide block 13 on one side of the connecting groove 12. Several anti-slip guide blocks 13 are movably inserted into several connecting grooves 12 respectively. The height of the connecting groove 12 is greater than the length of the anti-slip guide block 13. When the lower pressing seat 10 contacts the weighing module 11, there are gaps at both ends of the connecting groove 12 and the anti-slip guide block 13. The lower end of the lifting compensation seat 8 is provided with an inclination lifting adaptation groove 16. A T-shaped constraint guide rod 17 is vertically provided in the center of the first ring 7. The T-shaped constraint guide rod 17 is inserted into the inclination lifting adaptation groove 16 and is sleeved with an adaptation spring 18. When the goods are placed on the contact support plate 5, the contact support plate 5 squeezes the four weighing modules 11 through the four lower pressing seats 10 to achieve the measurement of the goods above the contact support plate 5. When the weight of the items is large, the items are removed before the transport and handling frame 1 travels and transports;

[0038] Adjust the support assembly, the adjustment support assembly is arranged in the installation groove 6, the adjustment support assembly includes a synchronous push plate 26 and a support cylinder 20, one side of the synchronous push plate 26 is connected to the two sides of the support cylinder 20, the upper end of the support cylinder 20 is in contact with the lower end of the contact support plate 5, and a second ring 19 is vertically provided in the installation groove 6 concentric with the first ring 7. An annular cavity is sandwiched between the second ring 19 and the first ring 7. The support cylinder 20 is vertically movably inserted into the annular cavity, and a support contact ring 21 is horizontally provided on the upper end of the support cylinder 20 In the weighing state, there is a gap between the upper end of the support contact ring 21 and the lower end of the contact support plate 5. After the goods are weighed, if the weight is appropriate, the four support contact rings 21 are lifted and abut against the lower end of the contact support plate 5, and the contact support plate 5 is slightly lifted, so that the lower pressure seat 10 moves a certain distance in the anti-slip guide block 13 through the connecting groove 12. At this time, the lower pressure seat 10 is away from the weighing module 11, and the weight of the goods above the contact support plate 5 will not be directly transferred to the upper end of the weighing module 11, thereby improving the service life of the weighing module 11.

[0039] Four guide pin grooves 22 are symmetrically provided on the four sides of the second ring 19. The support cylinder 20 is provided with a guide pin shaft 23 on one side of the guide pin shaft 23. The four guide pin shafts 23 are movable through the four guide pin grooves 22 respectively. Moving slide grooves 24 are horizontally provided on both sides of the installation groove 6 close to the second ring 19. An adjusting telescopic cylinder 25 is horizontally provided on the side of the installation groove 6 away from the first ring 7. A synchronous push plate 26 is horizontally placed in the installation groove 6 and connected to one side of the adjusting telescopic cylinder 25. A pushing slide plate 27 is horizontally provided on both sides of the synchronous push plate 26 close to the moving slide groove 24. The two pushing slide plates 27 are respectively movably inserted into the two moving slide grooves 24. The two pushing slide plates 27 are close to one side of the second ring 19 There are support pins on both sides, and the support pins are movably sleeved with jacking arm plates 28. Two of the guide pins 23 of the support cylinder 20 respectively penetrate the guide pin grooves 22 and are correspondingly arranged with the two jacking arm plates 28, and the two jacking arm plates 28 are movably sleeved with the two guide pins 23 on the side away from the pushing slide plate 27. When the telescopic cylinder 25 is adjusted to push the synchronous push plate 26 to move, the push slide plate 27 slides stably along the moving slide groove 24. At this time, the push slide 27 pushes and lifts the guide pins 23 through the jacking arm plates 28. At this time, the support cylinder 20 is lifted and controlled under the cooperative guidance of the four guide pin grooves 22 and the guide pins 23, so that the upper end of the support contact ring 21 contacts the lower end of the contact support plate 5.

[0040] In this embodiment: when performing intelligent automatic transportation and handling of storage boxes or independently packaged products, the items are placed on the contact pallet 5. At this time, the contact pallet 5 weighs the weight of the goods above through the four weighing modules 11. When the weight is normal, the telescopic cylinder 25 is adjusted to control the lifting of the support contact ring 21. The support contact ring 21 slightly lifts the contact pallet 5 to avoid the weight above the contact pallet 5 directly acting on the weighing module 11, and the transport and handling frame 1 performs normal transportation and handling. When the weight exceeds the design weight, the system automatically determines, removes the overweight goods, and selects other suitable transport and handling mechanisms. When the weight of the items placed on the contact pallet 5 is uneven on the four sides, in order to avoid tipping over during transportation, on the side where the item is overweight, the four adjusting telescopic cylinders 25 are differentially controlled to make the contact pallet 5 slightly tilted, and support and compensate for the heavier side of the item to avoid tipping over during movement.

[0041] Embodiment 2: On the basis of embodiment 1, a holding component is provided to mechanically assist the support of the adjustment telescopic cylinder 25. The holding component is horizontally arranged at the upper end of the mounting groove 6 of the mounting bracket 4. The holding component includes a holding control box 29 and a positioning tooth plate 32. One side of the positioning tooth plate 32 is connected to the synchronous push plate 26. The upper end of the synchronous push plate 26 is horizontally symmetrically provided with a plurality of holding racks 30. A spring cavity 31 is provided on one side of the holding control box 29 close to the holding rack 30. A positioning tooth plate 32 is horizontally provided in the spring cavity 31. The lower end of the positioning tooth plate 32 is movable through the lower end of the holding control box 29. The positioning tooth plate 32 A plurality of reference racks are symmetrically provided at the lower end of the holding control box 29, and the holding rack 30 is meshed with the reference rack. An anti-slip plate 33 is horizontally provided on one side of the positioning tooth plate 32 placed in the spring chamber 31, and a spring guide rod 34 is vertically symmetrically provided on the upper end of the anti-slip plate 33. The upper end of the spring guide rod 34 movably passes through the upper end of the holding control box 29, and a return spring 35 is sleeved on one side of the spring guide rod 34 located in the holding control box 29. When the adjusting telescopic cylinder 25 pushes the synchronous push plate 26 to move, the holding rack 30 can push the positioning tooth plate 32 to reciprocate and squeeze the return spring 35, thereby realizing self-clamping after the synchronous push plate 26 moves.

[0042] A control chamber is provided on one side of the control box 29 close to the spring chamber 31, and an auxiliary telescopic cylinder 36 is horizontally provided in the control chamber, and a synchronization plate is horizontally provided on one side of the auxiliary telescopic cylinder 36 close to the spring chamber 31, and two limit rods 37 are symmetrically provided on one side of the synchronization plate, and one side of the two limit rods 37 is movably inserted into the spring chamber 31. When the reference rack of the positioning tooth plate 32 is engaged with the retaining rack 30, the limit rod 37 is inserted into one side of the spring chamber 31 and horizontally abuts against the upper end of the anti-slip plate 33. When the limit rod 37 abuts against the upper end of the anti-slip plate 33, the positioning tooth plate 32 cannot move up and down. At this time, the self-clamping of the synchronous push plate 26 maintains a fixed posture, which relieves the support force of the adjustment telescopic cylinder 25 and improves the support safety of the equipment.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
