[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1

The lifting mechanism drives the cargo platform 5 to rise and fall along the column 9. The traveling mechanism is configured on the column 9. The traveling mechanism includes at least one set of overhead rail traveling components and at least two sets of ground rail traveling components. The at least two sets of ground rail traveling components are arranged at intervals along the direction of the ground rail on the column 9.

[0033] The overhead rail walking assembly includes a mounting seat 12 and two groups of wheel seats 13 respectively hinged at both ends of the mounting seat 12, and overhead rail walking wheels 14 are provided on the two groups of wheel seats 13, and a pre-tightening adjustment assembly is provided between the two groups of wheel seats 13. The two groups of overhead rail walking wheels 14 are clamped on both sides of the overhead rail through the pre-tightening adjustment assembly, and at least one overhead rail walking wheel 14 is provided with an overhead rail walking motor 20.

[0034] The preload adjustment assembly includes a screw rod 15 , both ends of which are connected to the two wheel sets respectively. A preload spring 16 is provided at at least one end of the screw rod 15 , and the preload spring 16 is used to clamp the two sets of overhead rail running wheels 14 to the overhead rail.

[0035] The column 9 is configured as a single column 9 or a double column 9 . When the column 9 is configured as a double column 9 , the double columns 9 are fixedly connected by a crossbeam 4 .

[0036] At least one pair of ground rail guide wheels 1 is provided at the bottom of the column 9, and at least one pair of ground rail guide wheels 1 is clamped on the ground rail. At least one pair of ceiling rail guide wheels 18 is provided at the top of the column 9, and at least one pair of ceiling rail guide wheels 18 is clamped on the ceiling rail.

[0037] At least one group of the overhead rail running components and at least two groups of the ground rail running components all use servo motors, and laser ranging elements are provided at the upper and lower ends of the column 9. At least one group of the overhead rail running components and at least two groups of the ground rail running components perform distributed control by detecting data through the laser ranging elements.

[0038] The lifting mechanism includes a guide mechanism and a rack and pinion lifting mechanism. The rack and pinion lifting mechanism is provided with multiple groups, and the multiple groups of rack and pinion lifting mechanisms are respectively driven by correspondingly configured driving motors.

[0039] The guide mechanism includes at least one set of clamping wheels, and the guide mechanism is arranged on the cargo platform 5. At least one set of clamping wheels clamps the column 9 in the middle to ensure the stability of the cargo platform 5 when it is raised and lowered.

[0040] The ground rail running assembly includes a ground rail running wheel 2 and a ground rail running motor 3 driving the ground rail running wheel 2 to rotate, and the ground rail running wheel 2 is supported on the ground rail.

[0041] The top and bottom of the two columns 9 are connected by a crossbeam 4, a first driving clamping device is provided on the upper crossbeam 4, and a second driving clamping device is provided at the bottom of the lower crossbeam 4, the first driving clamping device includes mounting seats 12 respectively arranged on both sides of the upper crossbeam 4, the mounting seats 12 are provided with wheel seats 13 through hinge shafts, the two wheel seats 13 are connected to each other by a screw 15, one end of the screw 15 abuts against the wheel seat 13, and the other end of the screw 15 is provided with a nut 17, a pre-tightening spring 16 is sleeved on the screw 15 between the nut 17 and the wheel seat 13, and one of the wheel seats 13 is provided with a ceiling rail walking wheel 14 and a ceiling rail walking motor 20 that drives the ceiling rail walking wheel 14.

[0042] By arranging a first driving clamping device on the upper end of the crossbeam 4 and a second driving clamping device at the bottom of the lower end of the crossbeam 4, and simultaneously activating and deactivating the first driving clamping device and the second driving clamping device, the stability of the device during movement can be ensured, and shaking of the device during movement can be avoided;

[0043] Since the overhead rail traveling wheel 14 on the wheel seat 13 can rotate on the mounting seat 12, the pre-tightening spring 16 can be compressed by rotating the nuts 17 on the two screws 15. The pre-tightening spring 16 applies elastic force in the direction of the wheel seat 13 to ensure that the two wheel seats 13 are close to each other. When the two wheel seats 13 are close to each other, the overhead rail traveling wheels 14 installed on the wheel seat 13 are close to each other. Since the upper end of the track is clamped between the two overhead rail traveling wheels 14, it is convenient for the two overhead rail traveling wheels 14 to abut against each other. When the overhead rail traveling motor 20 drives one of the overhead rail traveling wheels 14 to rotate, it can cooperate with the second driving clamping device at the bottom of the lower end cross beam 4 to drive the device to move. The upper and lower ends of the device move and stop at the same time, which can avoid shaking of the device during movement, ensure the safety of the device during operation, and improve the working efficiency of the device.

[0044] Both ends of the upper cross beam 4 are provided with guide clamping devices, each of which includes a connecting plate 19 . Both ends of the connecting plate 19 are provided with ceiling rail guide wheels 18 .

[0045] The overhead rail guide wheels 18 at both ends of the upper crossbeam 4 can clamp the upper rail to ensure the stability of the device during movement, avoid twisting when the device moves, and cause damage to the first drive clamping device. The overhead rail guide wheels 18 can disperse the force generated by the twisting when the device moves, thereby improving the stability and service life of the device.

[0046] The bottom ends of the lower cross beam 4 are respectively provided with ground rail running wheels 2, and the side of the lower cross beam 4 is provided with a ground rail running motor 3 that drives the ground rail running wheels 2. The ground rail running motor 3 and the overhead rail running motor 20 are of the same model and specification, and the overhead rail running wheels 14 and the ground rail running wheels 2 have the same diameter.

[0047] Since the diameters of the overhead rail running wheel 14 and the ground rail running wheel 2 are the same, when the overhead rail running motor 20 drives the overhead rail running wheel 14 to rotate, the ground rail running motor 3 can drive the ground rail running motor 3 to rotate synchronously, ensuring that the first drive clamping device and the second drive clamping device work at the same time, driving the device to move up and down synchronously or stop, thereby improving the stability of the device.

[0048] A set of ground rail guide wheels 1 is respectively provided at both ends of the lower end cross beam 4 .

[0049] The working principle of the overhead rail guide wheel 18 is the same as that of the overhead rail guide wheel 18. By arranging the ground rail guide wheels 1 at both ends of the lower end cross beam 4, the ground rail guide wheel 1 and the overhead rail guide wheel 18 can cooperate with each other, which can further ensure the stability of the device during movement, avoid twisting of the device during movement, and cause damage to the first drive clamping device. The overhead rail guide wheel 18 can disperse the force generated by the twisting when the device moves, thereby improving the stability and service life of the device.

[0050] The surfaces of the overhead rail wheels 14 and the ground rail wheels 2 are both provided with an anti-skid and wear-resistant layer. The anti-skid and wear-resistant layer can increase the friction between the overhead rail wheels 14 and the ground rail wheels 2 during movement, prevent the device from being unable to move synchronously due to idling, improve the stability of the device during operation, and ensure the service life of the device.

[0051] A cargo platform 5 is provided between the two columns 9. Brackets 11 are provided on both sides of the cargo platform 5 close to the columns 9. A lifting mechanism that moves along the length direction of the columns 9 is provided on the side of the brackets 11. A telescopic fork 6 is provided on the top of the cargo platform 5. The lifting mechanism includes a lifting motor 7 installed on the brackets 11. A hoist gear 8 is installed on the power output end of the lifting motor 7. A rack 10 that is compatible with the hoist gear 8 is provided on the column 9. The rack 10 is provided on both sides of the column 9. A lifting motor 7 is provided on both sides of the width direction of the bracket 11. The lifting motor 7 can drive the hoist gear 8 to rotate. The hoist gear 8 is meshed with the rack 10 on the corresponding side of the column 9.

[0052] The goods that need to be moved can be brought to the cargo platform 5 by the telescopic fork 6, and the lifting mechanism on the bracket 11 can be used to move the goods on the cargo platform 5 up and down. By arranging racks 10 on both sides of the column 9 and arranging a lifting motor 7 and a lifting gear 8 that are compatible with the rack 10 on the bracket 11, the weight on the cargo platform 5 can be evenly distributed to the four racks 10 on the four sides of the two columns 9, evenly sharing the gravity of the goods, reducing the load of each lifting motor 7 when working, and reducing the extra power consumption or heat loss of each motor, thereby improving the energy efficiency of the system and ensuring the service life of the motor.

Conversely, the wire rope 21 is released from the winch 22, the wire rope 21 becomes longer, and the cargo platform 5 is lowered.
