Abstract

An adjustable intermediate disk body of large double-layer cage comprises cage columns, a main intermediate disk body, and a chain block and a connecting piece. An intermediate disk guide rail beam is arranged on the inner side of the cage columns, wedge bases are symmetrically arranged on the two sides of the lower part of the intermediate disk guide rail beam, a limited block with a bolt hole is arranged on the upper part of the intermediate disk guide rail beam, and an anti-disengaging plate is arranged on the intermediate disk guide rail beam. Intermediate disk wedge bodies, which match the wedge faces of the wedge bases and can only move vertically along the intermediate disk guide rail beams, are arranged on the two side faces of the main intermediate disk body, at positions corresponding to the intermediate disk guide rail beams; an intermediate disk guide wheel that is fitted with the intermediate disk guide rail beam and an intermediate disk guide wheel seat with a bolt hole are arranged on the upper part of the intermediate disk wedge body.

Dependent claims

An adjustable intermediate disk body of large double-layer cage, comprising:

cage columns;
a main intermediate disk body arranged in between the cage columns;
and
a chain block and a connecting piece connected to a cage suspension board,
wherein, an intermediate disk guide rail beam is arranged on an inner side of the cage columns and slidably connected to the main intermediate disk body operable to move up and down,
wedge bases are arranged symmetrically on the two sides of a lower part of the intermediate disk guide rail beam and designed to fix a minimum descending position of the main intermediate disk body, each wedge base including a wedge face,
a limited block is arranged on an upper part of the intermediate disk guide rail beam,
a first bolt hole is arranged on the limited block and is designed to fix a maximum ascending position of the main intermediate disk body;
intermediate disk wedge bodies are arranged on two side faces of the main intermediate disk body at a position aligning with and at least partiailly on either side of each of the intermediate disk guide rail beams, which are shaped to inversely correspond to the shape of the wedge faces of the wedge bases;
and
at least one intermediate disk guide wheel rotably connected to the intermediate disk wedge body that is operably connected to the intermediate disk guide rail beam to enable the main intermediate disk body to translate with respect to the intermediate disk guide rail beam;
and
