Detailed Description

As shown in fig. 1-3, a device hinders more that runner inclined plane operation overhauls hanging flower basket, including flexible landing leg, flexible landing leg is including a support section of thick bamboo 2 and support lead screw 3, and a support section of thick bamboo 2 lower extreme is equipped with backup pad 4, and a support section of thick bamboo 2 upper end is equipped with support screw 5, supports screw 5 and support lead screw 3 cooperation, and a support section of thick bamboo 2 suit is in the support lead screw 3 outside, and support lead screw 3 upper end is connected with hanging main shaft 7 through connecting piece 6, hangs main shaft 7 for the pivot of the big gyro wheel of overhauing the hanging flower basket.

When the obstacle crossing device is used, at least two sets of obstacle crossing devices are arranged and are symmetrically arranged along the suspension main shaft 7.

Since the support screw 5 is engaged with the support screw rod 3, the support screw rod 3 slides in the support cylinder 2 by rotating the support screw 5, thereby extending or shortening the entire apparatus. When the hanging basket is used in a concrete mode, when the hanging basket for operation maintenance is moved to sink into the pit, the telescopic supporting legs are rotated towards the upper slope surface of the flow channel to enable the supporting plate 4 to be attached to the bottom plate of the upper slope surface flow channel, and the supporting screw 5 is rotated manually to enable the supporting screw rod 3 to extend to jack up the hanging basket. Through mechanics principle analysis, the resistance of the lifting traction steel wire rope is greatly reduced, and therefore the obstacle crossing function of the hanging basket can be easily achieved.

Preferably, the supporting plate 4 is provided with an ear plate 8, and the lower end of the supporting cylinder 2 is hinged with the ear plate 8 through a pin shaft.
