Description

Technical Field

[0001] This invention relates to the field of sorting cart technology, and more specifically, to a pallet sorting cart. Background Technology

[0002] In the sorting process of logistics sorting machines, the tilting sorting trolley uses a structure where the track is set on the pallet and the tilting wheels are set on the pallet frame. The length of the tilting track is limited. Given a certain length and height, the tilting angle of the tilting track cannot be adjusted. Moreover, if a low tilting angle is to be achieved for a transitional tilt, the pallet of the sorting trolley needs to be made very long to meet the tilting angle requirements of the sorting trolley, thus requiring a long guide rail distance, which occupies space and is not suitable for industrial applications.

[0003] Therefore, there is an urgent need for a pallet sorting trolley. Summary of the Invention

[0004] The purpose of this invention is to provide a pallet sorting trolley to solve the problems in the prior art and enable rapid sliding and sorting of goods.

[0005] This invention provides a pallet sorting trolley, comprising: a frame, a walking power mechanism disposed in the middle of the frame, a pallet frame disposed on the walking power mechanism, a pallet disposed on the pallet frame, tilting wheels disposed on both sides of the bottom front end of the pallet, wherein one of the tilting wheels can cooperate with a tilting track tilted on the corresponding side of the frame, and an automatic locking device disposed at the bottom of the pallet.

[0006] In the pallet sorting trolley described above, preferably, the bottom center of the pallet is hinged to the pallet frame; the lower end of the pallet frame is mounted on the walking power mechanism, which is mounted in the middle of the frame; and axles are provided on both sides of the tilting wheels.

[0007] In the pallet sorting trolley described above, preferably, the automatic locking device includes a locking member and a locking pin, wherein the locking member has an L-shaped structure, and the corner of the locking member is hinged to the bottom of the pallet 1 via a hinge shaft, and the locking member is located behind the tilting wheel, and the horizontal free end of the locking member is hinged to the axle of the tilting wheel.

[0008] In the pallet sorting trolley described above, preferably, the pallet has a through hole through which the axle can pass, the through hole being a vertical strip-shaped hole, and the lower vertical end of the locking member has a U-shaped groove; the locking pin is fixedly connected to the front end face of the pallet frame, and the locking pin is located below the hinge between the pallet and the pallet frame, and the U-shaped groove can be movably engaged with the locking pin.

[0009] In the pallet sorting trolley described above, preferably, one end of the hinge shaft extending outside the pallet is connected to a torsion spring, one free end of the torsion spring abuts against the front bottom of the pallet, and the other free end presses against the upper side of the axle.

[0010] In the pallet sorting trolley described above, preferably, a rubber sleeve is fitted onto the axle of the tilting wheels, and the rubber sleeve is movably embedded in the through hole.

[0011] In the pallet sorting trolley described above, preferably, the tilting track includes an inclined track, the rear end of which is hinged to the frame, a drive linkage is connected near the center of the inclined track, a drive wheel is provided at the lower end of the drive linkage, a travel track is provided below the drive wheel, and the drive wheel can travel along the travel track; a telescopic cylinder is connected to one end of the axle of the drive wheel.

[0012] In the pallet sorting trolley described above, preferably, one end of the drive linkage is hinged to the inclined track near the center; one end of the telescopic cylinder is hinged to the protruding portion on one side of the axle of the drive wheel, and the other end of the telescopic cylinder is hinged to the frame.

[0013] In the pallet sorting trolley described above, preferably, the pallet is fixedly connected to a rotating frame via multiple shafts, and the rotating frame has connecting ears at its lower front and rear ends, with each connecting ear hinged to the pallet frame.

[0014] This invention provides a pallet sorting trolley with tilting wheels installed at the bottom of the pallet. When it reaches the tilting track at a predetermined position on the frame, the tilting track initially engages an automatic locking device. After the automatic locking device is engaged, the trolley continues to move forward, thus tilting the pallet and allowing goods to slide down for sorting. The length of the tilting track can be easily set, allowing for a gradual transition in the tilting process of the sorting trolley and providing a longer buffer during pallet tilting. Without altering the existing structure or raising the height on one side, only the length of the tilting track needs to be changed to achieve a slow tilting of the sorting trolley. Furthermore, without changing the existing structure, the tilt angle of the tilting track can be varied, allowing for adjustment of the tilting angle of different sorting trolleys. This facilitates setting different tilting angles for different goods that require overcoming different friction forces. Attached Figure Description

[0030] like Figures 1-8 As shown, the pallet sorting trolley provided in this embodiment includes: a frame 3, a walking power mechanism 2 is provided in the middle of the frame 3, a pallet frame 4 is provided on the walking power mechanism 2, a pallet 1 is provided on the pallet frame 4, and tilting wheels 16 are provided on both sides of the bottom front end of the pallet 1. One of the tilting wheels 16 can cooperate with the tilting track 5 tilted on the corresponding side of the frame 3. An automatic locking device is provided at the bottom of the pallet 1.

[0031] The pallet 1 has a U-shaped groove structure with openings at both ends. The bottom center of the pallet 1 is hinged to the pallet frame 4; the lower end of the pallet frame 4 is mounted on the walking power mechanism 2, which is mounted in the middle of the frame 3; and the tilting wheels 16 are provided with axles 9 on both sides.

[0032] Furthermore, the automatic locking device includes a locking member 6 and a locking pin 7, wherein the locking member 6 has an L-shaped structure, and the corner of the locking member 6 is hinged to the bottom of the tray 1 via a hinge shaft 8, and the locking member 6 is located on the rear side of the tilting wheel 16, and the horizontal free end of the locking member 6 is hinged to the wheel axle 9 of the tilting wheel 16.

[0033] During operation, the tilting wheels 16 are installed at the bottom of the pallet 1. When the tilting track 5, which is tilted and set at a predetermined position on the frame 3 (e.g., near the sorting position), is reached, the tilting track 5 initially lifts the tilting wheels 16, thereby driving the locking member 6 to rotate. This disengages the U-shaped slot 11 below the locking member 6 from the locking pin 7, opening the automatic locking device. The sorting trolley then continues to move forward, tilting the pallet 1 on the tilting track 5 to complete the rapid sliding and sorting of goods.

[0034] Furthermore, the tray 1 has a through hole 10 through which the axle 9 can pass. The through hole 10 is a vertical strip hole. The lower vertical end of the locking member 6 has a U-shaped groove 11. The locking pin 7 is fixedly connected to the front end face of the tray frame 4, and the locking pin 7 is located below the hinge between the tray 1 and the tray frame 4. The U-shaped groove 11 can be movably inserted into the locking pin 7.

[0035] Furthermore, a torsion spring 12 is connected to one end of the hinge shaft 8 that extends outside the tray 1. One free end of the torsion spring 12 abuts against the front bottom of the tray 1, and the other free end presses against the upper side of the wheel axle 9.

[0036] Furthermore, a rubber sleeve 15 is fitted onto the axle 9 of the tilting wheel 16. The rubber sleeve 15 is movably embedded in the through hole 10, and the rubber sleeve 15 can play a role in shock absorption and noise reduction.

[0037] Furthermore, the tilting track 5 includes an inclined track 501, the rear end of which is hinged to the frame 3. A drive link 502 is connected to the inclined track 501 near its center. A drive wheel 503 is provided at the lower end of the drive link 502. A travel track 505 is provided below the drive wheel 503. The drive wheel 503 can travel along the travel track 505. A telescopic cylinder 504 is connected to one end of the axle of the drive wheel 503.

[0038] Furthermore, one end of the drive linkage 502 is hinged to the inclined track 501 near its center; one end of the telescopic cylinder 504 is hinged to the protruding portion on one side of the axle of the drive wheel 503, and the other end of the telescopic cylinder 504 is hinged to the frame 3. Through the extension and retraction of the telescopic cylinder 504, the angle between the drive linkage 502 and the track 505 can be adjusted, thereby adjusting the height of the upper end of the inclined track 501, and consequently adjusting the tilting angle of the sorting trolley. After sorting is completed, controlling the extension and retraction of the telescopic cylinder 504 returns the inclined track 501 to a horizontal position, allowing the sorting trolley to continue moving forward.

[0039] Furthermore, the tray 1 is fixedly connected to a rotating frame 14 via multiple shafts 13. Connecting ears are provided at both the front and rear ends of the lower side of the rotating frame 14, and each connecting ear is hinged to the rotating frame 14. The tray 1 is lightweight and has ample bottom space, facilitating the installation of tilting wheels 16 and an automatic locking device.

[0040] The pallet sorting trolley provided in this embodiment of the invention has tilting wheels installed at the bottom of the pallet. When it reaches the tilting track at a set position on the frame, the tilting track initially engages the automatic locking device. After the automatic locking device is engaged, it continues to move forward, thereby tilting the pallet and enabling the goods to slide down for sorting. The length of the tilting track is easily adjustable, which facilitates the gradual transition of the tilting process of the sorting trolley and allows for a longer buffer during the pallet tilting process. Without altering the existing structure or the height of one side, only the length of the tilting track needs to be changed to achieve a slow tilting of the sorting trolley. The tilt angle of the tilting track can also be adjusted without altering the existing structure, allowing for the adjustment of the tilting angle of different sorting trolleys. This makes it easy to set different tilting angles for different goods that need to overcome different friction forces.
