Technical Field
[0001] This invention relates to a shuttle trolley, and more particularly to a heavy-duty, low-position lifting shuttle trolley system. Background Technology
[0002] Shuttle carts are a common piece of equipment in automated warehousing, mainly used at the docking points of multiple production stations on both sides. Compared with conveyor lines, they have the advantages of low cost and low energy consumption. Heavy-duty shuttle carts are generally quite large in overall structure, and the addition of lifting functions further increases their overall size. The hydraulic lifting platform at the bottom of the shuttle cart increases the conveying and docking height of the shuttle cart, and correspondingly, the conveying height of the docking stations on both sides must also increase accordingly. This makes manual operation at the docking stations on both sides very inconvenient. In order to meet the height requirements of the manual operation stations on both sides and achieve layered delivery docking at the docking points, it is necessary to develop a low-position heavy-duty lifting shuttle cart system.
[0003] Since the shuttle's task is to deliver heavy-duty goods to the conveyor lines on each floor, a lifting platform needs to be installed on the shuttle, and a conveyor is set on the lifting platform. The lifting of the platform enables the conveyor on the platform to be horizontally connected with the conveyor lines at different heights. Existing lifting platforms generally use a top lifting mechanism, which can easily cause instability when the center of gravity is high after the goods are lifted. How to achieve smooth lifting of heavy-duty goods has become a problem that needs to be solved on site. How to achieve heavy-duty conveying with a double-track arrangement, and how to achieve low-level docking conveying by nesting the docking conveyor components, lifting platform, and box-type frame components layer by layer into the track, are key issues that need to be solved on site. Summary of the Invention

[0028] A lifting platform mechanism for a heavy-duty, low-position lifting shuttle trolley includes a box-shaped frame 5. The box-shaped frame 5 is movably mounted on a track 1 via a pair of driving wheels 8 and a pair of driven wheels 16. A conveyor 36 is installed on a lifting platform 28 within the box-shaped frame 5. Heavy-duty goods are placed on the conveyor 36. Through the horizontal movement of the box-shaped frame 5 and the lifting of the lifting platform 28, the heavy-duty goods are transferred to the corresponding goods conveying line. A lifting motor mounting base 17 is fixedly installed at the top of the middle of the left outer frame of the box-shaped frame 5. A lifting motor 18 is installed on the lifting motor mounting base 17. The lifting motor 18 provides power for the lifting of the lifting platform 28. Below the lifting motor 18, the box-shaped frame... A pair of lifting shaft bearing seats 20 are provided on the left outer frame of component 5. A lifting shaft 21 is provided in the pair of lifting shaft bearing seats 20. A lifting drive sprocket 22 is fixedly provided in the middle of the lifting shaft 21. A lifting motor drive sprocket 23 is provided on the output shaft of the lifting motor 18. An annular lifting drive chain 24 is provided between the lifting drive sprocket 22 and the lifting motor drive sprocket 23. The output shaft of the lifting motor 18 drives the lifting drive sprocket 22 to rotate through the lifting motor drive sprocket 23 and the annular lifting drive chain 24, thereby driving the lifting shaft 21 to rotate in the pair of lifting shaft bearing seats 20. A front lifting sprocket 25 is fixedly provided at the front of the lifting shaft 21, and a rear lifting sprocket 26 is fixedly provided at the rear of the lifting shaft 21. The rotation of the lifting shaft 21 drives the front lifting sprocket 25 and the rear lifting sprocket 26 to rotate synchronously. A front U-shaped lifting chain right end fixing seat 19 is provided at the front of the top of the right outer frame of the box-shaped car body frame 5, and a rear U-shaped lifting chain right end fixing seat 34 is provided at the rear of the top of the right outer frame of the box-shaped car body frame 5. A front left redirecting sprocket 29, a front right redirecting sprocket 30, a rear left redirecting sprocket 31, and a rear right redirecting sprocket 32 are respectively provided on the lower surface of the lifting platform 28, which is movably arranged inside the box-shaped car body frame 5. One end of the front lifting chain 33 is fixedly connected to the front U-shaped lifting chain right end fixing seat 19, and the other end of the front lifting chain 33 passes through the front right redirecting sprocket 30, the front left redirecting sprocket 29, and the front lifting sprocket in sequence. The rear lifting chain 25 forms a U-shaped lifting and lowering mechanism for the lifting platform 28; one end of the rear lifting chain 35 is fixedly connected to the right end fixed seat 34 of the rear U-shaped lifting chain, and the other end of the rear lifting chain 35 passes through the rear right redirecting sprocket 32, the rear left redirecting sprocket 31 and the rear lifting small sprocket 26 in sequence to form a U-shaped lifting and lowering mechanism for the lifting platform 28; when the lifting motor 18 rotates in the forward direction, the left end of the front lifting chain 33 engages with the front lifting small sprocket 25, so that the front lifting chain 33 forms an upward U-shaped lifting mechanism for the lifting platform 28, and at the same time, the left end of the rear lifting chain 35 engages with the rear lifting small sprocket 26, so that the rear lifting chain 35 forms an upward U-shaped lifting mechanism for the lifting platform 28, thereby achieving a smooth lifting of the lifting platform 28;When the lifting platform 28 needs to be lowered, the lifting motor 18 rotates in the opposite direction. The front lifting chain 33, through the front lifting sprocket 25, and the rear lifting chain 35, through the rear lifting sprocket 26, simultaneously release both chains downwards, allowing the lifting platform 28 to descend smoothly until it lands on the lower surface inside the box-shaped car frame 5. This invention achieves the vertical lifting and lowering of goods on the conveyor 36 through the vertical lifting operation of the lifting platform 28 inside the box-shaped car frame 5 of the heavy-duty lifting shuttle trolley, ultimately realizing the conversion of goods at different heights on both sides of the conveyor interface.
[0029] A front lifting chain collection box 27 is provided on the left outer frame of the box-shaped car frame 5 directly below the front lifting sprocket 25; a rear lifting chain collection box is provided on the left outer frame of the box-shaped car frame 5 directly below the rear lifting sprocket 26. The lifting chain collection box is also called the chain collection groove. When the lifting platform 28 is lifted, the left end of the lifting chain enters the chain collection groove and is collected in an orderly manner. When the lifting platform 28 is lowered, the lifting chain is lifted from the chain collection groove and passes through the lifting sprocket to realize the lowering of the lifting platform 28. A conveyor 36 is provided in the lifting platform 28. A front chain anti-jump sleeve 41 is provided on the outer end of the front lifting sprocket 25, and a rear chain anti-jump sleeve 42 is provided on the outer end of the rear lifting sprocket 26.
[0030] A left lifting guide wheel assembly 37 is provided on the left outer facade of the rectangular lifting platform 28, a right lifting guide wheel assembly 38 is provided on the right outer facade of the rectangular lifting platform 28, a front lifting guide wheel assembly 39 is provided on the front outer facade of the rectangular lifting platform 28, and a rear lifting guide wheel assembly 40 is provided on the rear outer facade of the rectangular lifting platform 28. These four sets of guide wheels are fitted together with the inner vertical facade of the box-shaped vehicle frame 5. The arrangement of these guide wheels guides the lifting of the lifting platform 28. The shuttle car's traveling mechanism installs the driving wheel assembly and the driven wheel assembly on the outside of the box-shaped vehicle frame 5, allowing the driving wheel assembly and the driven wheel assembly to move together. The driven wheel component is higher than the bottom surface of the traveling support frame component. When the traveling support frame component is running on the ground track section 1, the bottom of the heavy-duty lifting shuttle trolley is sunk below the track support surface of the ground track section, which can reduce the overall process docking height. The lifting frame component is designed as a frame structure with the bottom completely hollowed out, so that the drive part of the docking conveyor component can be embedded in the space under the lifting platform component, maximizing the compression of the height dimension. The lifting platform component and the docking conveyor component are then embedded into the hollowed-out area at the bottom of the box-shaped frame component. Through layer nesting, the height dimension of the docking station is ultimately reduced.
[0031] The box-shaped car frame 5 is movably mounted on the track 1 via a pair of active wheels 8 and a pair of driven wheels 16. A C-shaped channel steel is installed at the front of the track 1, with a sliding contact line 2 and a positioning barcode 3 installed within it. A power take-off device 4 is connected to the sliding contact line 2, and the power take-off device 4 is connected to the electrical control box on the box-shaped car frame 5. The track 1 is supported by a standard 38Kg heavy-duty double-rail arrangement to ensure heavy load-bearing capacity. The track 1 is fixed to the track support plate by a standard track pressure plate, and the track support plate is fixed to the ground mounting plate by adjusting bolts. The ground mounting plate is fixed to the ground by chemical anchors. The heavy-duty lifting shuttle trolley is powered by a sliding contact line 2 installed on the track support plate, ensuring installation accuracy and reducing on-site adjustment work. During operation, the heavy-duty lifting shuttle trolley is accurately positioned horizontally using the positioning barcode 3.
