Reinforcing mechanism for drag chain connector of stacking machine in refrigeration house

Abstract

The utility model discloses a reinforcing mechanism for a drag chain connector of a stacking machine in a refrigeration house. The problem that the drag chain connector is prone to breakage is solved. A drag chain connector at the end of the drag chain is integrally wrapped by a U-shaped steel cover and then fixedly connected with a rack of the stacking machine, when the stacking machine works in a low-temperature environment of a refrigeration house, after the drag chain connector is subjected to low-temperature embrittlement, the U-shaped steel cover on the drag chain connector transmits unbalanced force transmitted by the drag chain to the drag chain connector, and then the drag chain connector is fixedly connected with the rack of the stacking machine. The U-shaped steel cover is directly transmitted to the drag chain fixing support, so that a drag chain connector made of plastic is prevented from being fractured at the connecting position.

Description

Technical Field

[0001] The invention relates to a stacker, in particular to a reinforcement mechanism for a drag chain joint of a stacker in a cold storage. Background Art

[0002] In automated high-bay warehouses, the power supply for stacker loading platforms is generally in the form of drag chains plus flexible cables. Currently, all drag chains on the market are made of plastic, and the drag chain connectors are also made of plastic. There is no problem with the normal use of drag chains at room temperature; but in high-bay cold storage, since the ambient temperature inside the warehouse is around -20°C, in such a low temperature environment, the plastic drag chain will become hard and brittle. At the same time, since the stacker frequently operates in a low-temperature environment, local stress will increase at the connection between the plastic drag chain connector and the stacker. The brittle drag chain connector is prone to breakage due to frequent swinging and stress, causing the stacker to alarm and shut down; the low temperature environment in the cold storage makes it very difficult to replace the drag chain; how to design a drag chain connector reinforcement mechanism to overcome the above problems has become a problem that needs to be solved on site. Summary of the Invention

[0003] The present invention provides a reinforcement mechanism for a drag chain joint of a stacker in a cold storage, which solves the technical problem that the drag chain joint is easily broken.

[0004] The present invention solves the above technical problems through the following technical solutions:
