[0002] Stacking cranes, also known as stackers, are the most important lifting and transportation equipment in high-bay warehouses and are a hallmark of high-bay warehouses. Their primary function is to traverse the aisles of a high-bay warehouse, depositing goods at the entrances into the shelves and retrieving them from the shelves. Traditional stackers typically consist of a lower traveling section, a platform, columns, and an upper traveling section. The lower traveling section is driven by a motor, with wheels directly driving the wheels along guide rails. The platform is lifted by wire ropes, and the upper traveling section uses side guide wheels to prevent the stacker from tipping over.

[0003] However, traditional stackers still have some areas that need improvement, such as: 1. Low positioning accuracy, making them unsuitable for applications requiring high precision; 2. The lower travel component cannot be started with high acceleration or sudden braking, otherwise the wheels will easily slip; the lifting speed of the platform component cannot be very fast, otherwise the wire rope will easily slip, resulting in unstable operation and low operating efficiency; 3. There is no relevant device to prevent the stacker from swaying back and forth, and the stability of the equipment operation needs to be improved. Therefore, there is an urgent need to design a high-precision and high-speed stacker to solve the above problems. Utility Model Content

[0028] The utility model provides Figure 1-7 A high-precision, high-speed stacker crane as shown in FIG, comprising:

[0029] The lower walking assembly 100 includes a track 101 and a rack 102 and a walking frame 103 arranged on the top of the track 101. A driving motor 104 is fixed to the top of the walking frame 103. A driving gear 105 is keyed to the output shaft of the driving motor 104. The driving gear 105 is meshed with the rack 102. When the driving motor 104 is started, it can drive the driving gear 105 to rotate. Since the rack 102 is fixedly connected to the track 101, the driving gear 105 performs a linear motion along the rack 102, thereby driving the walking frame 103 to perform a linear motion along the track 101.

[0030] The column assembly 200 is fixed to the top of the traveling frame 103. The traveling frame 103 can drive the column assembly 200 to move together. The column assembly 200 includes a column 201, a mounting plate 202 fixed to one side of the column 201, and a rack 203 fixed to one side of the mounting plate 202;

[0031] The cargo platform assembly 300 is movably connected to the column 201. The cargo platform assembly 300 includes a lifting connection member 301 and a cargo platform 302 fixed to one side of the lifting connection member 301. A lifting motor 303 is fixed to the cargo platform 302. A driving gear 2 304 is keyed to the output shaft of the lifting motor 303. The driving gear 2 304 is meshed with the rack 203. When the lifting motor 303 is started, it can drive the driving gear 2 304 to rotate. Since the rack 203 is fixedly connected to the mounting plate 202, the driving gear 2 304 makes a linear motion along the rack 203, thereby driving the cargo platform 302 to make a linear motion along the rack 203.

[0032] The upper crossbeam assembly 400 is fixed on one side of the top end of the column 201. The upper crossbeam assembly 400 includes an upper crossbeam frame 401, side guide wheels 402 fixed at both ends of the upper crossbeam frame 401, and a mounting bracket 403 fixed on one side of the upper crossbeam frame 401. Top guide wheels 404 are fixed at both ends of the mounting bracket 403.

[0033] For example, see Figure 1 As shown, the system further includes a ceiling rail 500 , which is disposed directly above the upper crossbeam assembly 400 . The second side guide wheel 402 is in contact with the side surface of the ceiling rail 500 , and the top guide wheel 404 is in contact with the inner top surface of the ceiling rail 500 .

[0034] In this technical solution, the side guide wheel 402 can prevent the stacker from rocking left and right while traveling, and the top guide wheel 404 can prevent the stacker from rocking back and forth while traveling, thereby improving the stability of the equipment operation.

[0035] For example, see Figure 2 As shown, walking wheels 106 are provided at both ends of the walking frame 103, and the walking wheels 106 are in contact with the upper surface of the track 101. Side guide wheels 107 are provided on both sides of the walking wheels 106, and the side guide wheels 107 are in contact with the side surface of the track 101.

[0036] In this technical solution, the walking wheel 106 is provided to facilitate the movement of the walking frame 103 on the track 101, and the side guide wheel 107 is provided to prevent the walking frame 103 from deviating during operation, thereby preventing the walking frame 103 from detaching from the track 101.

[0037] For example, see Figure 1 and Figure 5-Figure 6 As shown, the cross-section of the lifting connector 301 is a U-shaped structure, and eight corresponding guide wheels 305 are provided on the two side panels of the lifting connector 301, among which four guide wheels 305 are respectively fitted with the left and right sides of the column 201, and the other four guide wheels 305 are respectively fitted with the front and rear sides of the mounting plate 202.

[0038] In this technical solution, by setting eight guide wheels 305, it is possible to ensure that the lifting connection member 301 is movably connected to the column 201. The four guide wheels 305 set on the left and right sides of the column 201 can prevent the lifting connection member 301 from shaking left and right. The four guide wheels 305 set on the front and rear sides of the mounting plate 202 can prevent the lifting connection member 301 from shaking back and forth, thereby improving the stability of the operation of the lifting connection member 301.

[0039] For example, see Figure 5-Figure 6 As shown, a fork drive assembly 306 is fixed on the cargo platform 302. The fork drive assembly 306 includes a stepper motor, a screw rod connected to the stepper motor, a nut seat that moves back and forth along the screw rod, a slider fixed on the nut seat, and a fork plate 307 fixed on the slider.

[0040] In this technical solution, the stepper motor drives the screw to rotate, and the nut seat on the screw makes a linear reciprocating motion along the screw. The nut seat drives the slider to move together, and then drives the fork plate 307 on the slider to make a linear reciprocating motion, realizing the function of forking goods.

[0041] For example, see Figure 5-Figure 6 As shown, a terminal box 308 is fixed on the cargo platform 302, and a terminal module is provided in the terminal box 308. The terminal module is electrically connected to the drive motor 104, the lifting motor 303, the stepping motor and the external power supply through wires.

[0042] In this technical solution, it is convenient to connect various electrical appliances together through the terminal module, which facilitates unified control.

[0043] For example, see Figure 7 As shown, tensioning assemblies 405 are provided at both ends of the bottom of the upper crossbeam frame 401. The tensioning assembly 405 includes a connecting piece 4051 and a tensioning bolt 4052. The connecting piece 4051 is fixedly connected to the upper crossbeam frame 401. The tensioning bolt 4052 is threadedly connected to the connecting piece 4051. The top of the tensioning bolt 4052 abuts against the bending part of the mounting bracket 403.

[0044] In this technical solution, the tensioning assembly 405 can attach the top guide wheel 404 to the ceiling rail 500 and can also prevent the top guide wheel 404 from becoming loose during use.

[0045] Working principle: When the high-precision and high-speed stacker is used, the drive motor 104 is first started, and the output shaft of the drive motor 104 drives the driving gear 105 to rotate, thereby driving the traveling frame 103 to move along the track 101. When the traveling frame 103 runs to the specified position, the drive motor 104 is turned off, and then the fork drive assembly 306 drives the fork plate 307 to retract and extend to complete the picking up of goods, and the drive motor 104 is started again. When the traveling frame 103 runs to the specified position, the drive motor 104 is turned off, and then the lifting motor 303 is started. The output shaft of the lifting motor 303 drives the driving gear 2 304 to rotate, thereby driving the cargo platform 302 to move along the column 201. When the cargo platform 302 runs to the specified height, the fork drive assembly 306 drives the fork plate 307 to retract and extend to complete the inventory. This high-precision, high-speed stacker has an advanced design, compact structure and reliable operation. The stacker is driven by the transmission of rack 102 and driving gear 105, and has the advantages of high precision, fast acceleration and high efficiency. The lifting and lowering drive of the cargo platform 302 is achieved by the transmission of rack 203 and driving gear 2 304, with a fast lifting speed and acceleration, which greatly improves the working efficiency of the equipment. The provision of a top guide wheel 404 can effectively prevent the stacker from shaking back and forth when walking, thereby improving the stability of the equipment operation.

[0046] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
