[0027] like Figure 1 —7, the utility model provides a vertical tail dock ladder frame with a safety detection device, including a lifting platform 1, a multi-layer ladder frame platform 2 is respectively arranged at the upper end of the lifting platform 1, a ladder 3 is arranged on one side of the lifting platform 1, and a vertical lifting column 4 is respectively arranged at the four corners of the lower end surface of the lifting platform 1, and the four lifting columns 4 are arranged on the same walking trolley 5; the lifting column 4 includes an outer column 6 and an inner column 7 that are plugged into each other, wherein the upper end of the outer column 6 is fixedly arranged on the lifting platform 1, and the lower end of the inner column 7 is fixedly arranged on the walking trolley 5, and a lifting mechanism is arranged between the outer column 6 and the inner column 7; a barcode scanner is arranged on the outer column 6, and a barcode is arranged on the inner column 7.

[0028] The lifting platform 1 is a horizontally arranged square plate structure.

[0029] The traveling trolley 5 is a horizontally arranged square frame structure, and a traveling wheel 8 is provided at each corner of the traveling trolley 5 .

[0030] The outer column 6 is a cylindrical structure with open upper and lower ends, and the inner column 7 is a cylindrical structure with an open upper end. The upper end of the inner column 7 is slidably inserted into the lower end opening of the outer column 6. The upper end of the outer column 6 is fixedly set at the lower end surface of the lifting platform 1, and the lower end of the inner column 7 is fixedly set at the upper end of one of the corners of the walking trolley 5.

[0031] The lifting mechanism includes a reduction motor 9 , a transverse transmission shaft 12 , a longitudinal transmission shaft 10 , a T-shaped commutator 11 , a right-angle commutator 13 , a screw rod 14 , and a nut 15 .

[0032] The reduction motor 9 is fixedly arranged at the center of the lower end surface of the lifting platform 1. The reduction motor 9 is provided with an output shaft on its front and rear sides respectively. A longitudinal transmission shaft 10 is fixedly arranged at each output shaft, and the longitudinal transmission shaft 10 is horizontally arranged along the front and rear directions.

[0033] A T-shaped commutator 11 is fixedly mounted in the middle of the front and rear edges of the lower end face of the lifting platform 1. The T-shaped commutator 11 includes an input shaft and two output shafts. The output shaft of the T-shaped commutator 11 is horizontally oriented toward the reduction motor 9, and the two output shafts of the T-shaped commutator 11 are respectively oriented toward the two lifting columns 4. The end of the longitudinal drive shaft 10, away from the reduction motor 9, is fixedly connected to the input shafts of the two T-shaped commutators 11. A transverse drive shaft 12 is fixedly mounted at each of the two output shafts of the T-shaped commutator 11, and is arranged horizontally in the left-right direction.

[0034] A right-angle commutator 13 is fixedly provided on the upper end of the outer column 6 of each lifting column 4, and the four right-angle commutators 13 are fixedly provided at the four corners of the lower end surface of the lifting platform 1. The right-angle commutator 13 includes an input shaft and an output shaft. The input shaft of the right-angle commutator 13 faces the side of the T-shaped commutator 11 on the same side, and the output shaft of the right-angle commutator 13 extends vertically downward into the interior of the outer column 6. The end of the transverse transmission shaft 12 away from the T-shaped commutator 11 is fixedly connected to the input shaft of the right-angle commutator 13. A vertical screw rod 14 is fixedly provided on the output shaft of the right-angle commutator 13, and the screw rod 14 extends into the interior of the inner rod. A nut 15 is fixedly provided at the upper end opening of the inner rod, and the screw rod 14 is screwed into the inside of the nut 15 at the upper end of the inner rod.

[0035] A barcode scanner is fixed to the lower opening of each lifting column 4's outer column 6. A barcode is affixed to the lower outer side of each lifting column's inner column 7. The barcode contains the inner column 7's identification information and preset lifting parameters. The barcode scanner corresponds to the barcode and is connected to the control system, enabling it to read and interpret the barcode information in real time.

[0036] The working principle of this utility model is:

[0037] After the reduction motor 9 is started, it drives the two longitudinal transmission shafts 10 to rotate synchronously, and the two longitudinal transmission shafts 10 drive the two T-type commutators 11 to move synchronously. The two T-type commutators 11 drive the four transverse transmission shafts 12 to rotate synchronously. The four transverse transmission shafts 12 drive the four right-angle commutators 13 to move synchronously. The four right-angle commutators 13 drive the four screw rods 14 to rotate inside the inner column 7. Because the screw rods 14 are screwed into the nuts 15 at the upper end of the inner column 7 and the nuts 15 cannot move, they drive the screw rods 14 to rise and fall as a whole. The screw rods 14 drive the right-angle commutators 13, the outer column 6, and the lifting platform 1 to rise and fall synchronously.

[0038] During the lifting process of the outer column 6, the control system simultaneously activates all barcode scanners to continuously scan the barcodes on the inner columns 7 for which they are responsible. By comparing the barcode information with the preset parameters, the control system can determine whether the actual position of each lifting column 4 is consistent with the expected position.

[0039] Safety detection and alarm mechanism: If the barcode scanning result of a lifting column 4 is abnormal (such as no barcode is detected, the position information does not match the expectation, etc.), the control system immediately identifies it as a fault state, triggers the alarm system (such as sound and light alarm), and suspends all lifting operations until the fault is eliminated.

[0040] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
