[0089] For example, the support column 500 can extend vertically, the support column 500 can be a hollow pipe, and the bottom end of the support column 500 is used to support the ground. The lifting column 501 is slidably installed on the support column 500, for example, the lifting column 501 can be inserted into the support column 500 and can slide up and down, and the top end of the lifting column 501 is used to support the maintenance platform 102 or the corridor platform 202. The transmission unit 502 includes a base 503, a lifting nut 504, a lead screw 505 and a transmission structure 506, the base 503 is arranged on the support column 500, for example, can be arranged at the top end of the support column 500, the lifting nut 504 is rotatably installed on the base 503, the lifting nut 504 has a threaded hole, the axial direction of the threaded hole of the lifting nut 504 can extend vertically, the transmission structure 506 is arranged on the base 503 and is connected to the lifting nut 504 to drive the lifting nut 504 to rotate, the lead screw 505 extends vertically, the lead screw 505 is arranged in the threaded hole of the lifting nut 504, and the lead screw 505 is threadedly connected to the threaded hole of the lifting nut 504. The bottom end of the lead screw 505 is connected to the bottom end of the lifting column 501.

[0090] In the embodiment, the transmission structure 506 can be connected with an external motor, when the motor drives the lifting nut 504 to rotate through the transmission structure 506, since the bottom end of the lead screw 505 is connected to the bottom end of the lifting column 501, the lead screw 505 will not rotate with the lifting nut 504, but move linearly along the vertical direction, thereby driving the lifting column 501 to lift relative to the supporting column 500, so as to realize the lifting of the maintenance platform 102 or the aisle platform 202. Since the lead screw 505 is connected to the bottom end of the lifting column 501, the force applied by the lifting column 501 to the lead screw 505 is mainly tension, so the lead screw 505 is not easy to bend and break, and has a longer service life.

[0091] It should be noted that the first lifting mechanism 103, the second lifting mechanism 203 and the third lifting mechanism 204 can also be other structures, for example, the lifting can also be realized through the cooperation of a gear and a rack, or an oil cylinder can be directly arranged.

[0092] In some embodiments of the utility model, as shown in Figure 14 The transmission structure 506 comprises a worm gear 507 and a worm 508, the worm gear 507 is rotatably arranged on the base 503 and coaxially connected with the lifting nut 504, the lead screw 505 is arranged in the worm gear 507, the worm 508 is rotatably arranged on the base 503 and engaged with the worm gear 507, and the worm 508 is used for connecting an external motor.

[0093] For example, the base 503 can be provided with a bearing, the worm gear 507 and the worm 508 are mounted on the bearing, the rotation axis of the worm gear 507 can extend along the vertical direction and is coaxial with the lifting nut 504, the lifting nut 504 can be fixedly connected to the top end of the worm gear 507 through welding or fasteners, of course, the lifting nut 504 can also be integrally formed with the worm gear 507, the rotation of the worm gear 507 can drive the lifting nut 504 to rotate, the rotation axis of the worm 508 can extend along the horizontal direction, the worm 508 is engaged with the worm gear 507, the worm 508 can be drivingly connected with an external motor to drive the worm 508 to rotate, the worm 508 drives the worm gear 507 to rotate, and the worm gear 507 drives the lifting nut 504 to rotate, so that the structure is simple and the operation is convenient.

[0094] It should be noted that the transmission structure 506 can also be other structures, for example, a gear can also be coaxially connected with the lifting nut 504, and the motor drives the gear to rotate.

[0095] In some embodiments of the utility model, as shown in Figure 14As shown, the bottom end of the worm wheel 507 is coaxially connected with a warning nut 510 through a key structure 509, the warning nut 510 can slide vertically relative to the worm wheel 507, and the lead screw 505 is threadedly connected with the warning nut 510. For example, the outer side wall of the warning nut 510 can be connected with the bottom end of the inner side wall of the worm wheel 507 through the key structure 509 such as a flat key or a spline, thereby achieving coaxial connection of the warning nut 510 with the bottom end of the worm wheel 507, the worm wheel 507 can drive the warning nut 510 to rotate, the height dimension of the key structure 509 can be smaller than the height dimension of the keyway for mounting the key structure 509, in this way, the warning nut 510 can slide vertically relative to the worm wheel 507 for adjustment, the bottom end of the warning nut 510 can protrude from the bottom end of the worm wheel 507, and the lead screw 505 is arranged in the warning nut 510 and is threadedly connected with the threaded hole of the warning nut 510.

[0096] During long-time use, the external thread of the lead screw 505 can be greatly worn, thereby not only affecting the cooperation between the lead screw 505 and the lifting nut 504, but also easily causing the lead screw 505 to fall off and cause a safety accident. In the embodiment, the warning nut 510 is arranged, the warning nut 510 rotates with the worm wheel 507 and can slide vertically relative to the worm wheel 507, and the warning nut 510 is threadedly connected with the lead screw 505. When the external thread of the lead screw 505 is slightly worn, the warning nut 510 is limited by the external thread of the lead screw 505 and cannot slide downward, when the external thread of the lead screw 505 is greatly worn and a large gap is formed between the external thread of the lead screw 505 and the internal thread of the warning nut 510 in the vertical direction, the warning nut 510 slides downward and lowers the height position, the wear condition of the external thread of the lead screw 505 can be directly understood by observing the height position of the warning nut 510, thereby the staff can be timely reminded to replace the lead screw 505, the use is more convenient, and the safety is better.
