Detailed Description

In order to facilitate understanding of the technical solutions of the present invention, the following detailed description is made with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in fig. 1 to 7, a cage structure of a construction hoist includes a guide rail frame 1 fixed on the ground, a cage body 2 capable of moving up and down relative to the guide rail frame 1 is disposed on a first side surface 11 of the guide rail frame 1, a rack 12 is fixedly disposed on the first side surface 11, a matched gear 21 is disposed at a corresponding position on the cage body 2, an engagement line between the rack 12 and the gear 21 is located at the center of the first side surface 11, and actually, the engagement line is also located at the center of the corresponding side surface on the cage body 2. In the prior art, the rack 12 and the gear 21 are arranged on two sides of the center of the guide rail frame 1, so that the meshing line formed by the meshing point of the rack 12 and the gear 21 deviates from the center of the guide rail frame, and because the driving force and the central line of the side surface of the cage body 2 are not on the same action line, a couple M can be generated, so that the cage body 2 has a rotation tendency, the acting force on the pulleys on the left side and the right side of the cage upright column 22 is increased, the use performance of the pulleys is influenced, and the stress state of the gear is more complicated.

In the embodiment, the meshing line of the rack 12 and the gear 21 is transferred to the center of the first side surface 11, and meanwhile, the meshing line is also located at the center of the corresponding side surface on the cage body 2, so that a couple M cannot be generated, the cage body 2 cannot be rotated, and the damage to the whole structure is reduced.

The suspension cage body 2 capable of moving up and down relative to the guide rail frame 1 is arranged on the second side surface 13 of the guide rail frame 1, and the second side surface 13 and the first side surface 11 are two opposite side surfaces on the guide rail frame 1. Namely, two suspension cage bodies 2 are arranged on one guide rail frame 1, so that the construction of a plurality of people is facilitated.
