Abstract
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. At present, 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 in the warehouse is around minus 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 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 easy to break.
[0004] The present invention solves the above technical problems through the following technical solutions: A reinforcement mechanism for a stacker drag chain joint in a cold storage, comprising a stacker frame and a stacker cargo platform, a drag chain fixed connection bracket is fixedly arranged on the stacker frame, a drag chain movable connection bracket is arranged on the stacker cargo platform, a plastic drag chain for powering the cargo platform is arranged between the drag chain fixed connection bracket and the drag chain movable connection bracket, the drag chain fixed connection bracket is a steel L-shaped connecting piece, a pair of left screw holes of the connecting plate and a pair of right screw holes of the connecting plate are respectively arranged on the lower end horizontal plate of the L-shaped connecting piece, a drag chain end head is arranged at the end of the drag chain, and left ports are respectively arranged on the drag chain end heads A U-shaped frame and a right U-shaped frame, a pair of left frame top connecting screw holes are arranged at the top of the left U-shaped frame, a pair of right frame top connecting screw holes are arranged at the top of the right U-shaped frame, a pair of left screw holes of the connecting plate are arranged correspondingly to the pair of left frame top connecting screw holes, a pair of right screw holes of the connecting plate are arranged correspondingly to the pair of right frame top connecting screw holes; a pair of left frame side frame connecting screw holes are arranged correspondingly on the front side frame and the rear side frame of the left U-shaped frame, a pair of right frame side frame connecting screw holes are arranged correspondingly on the front side frame and the rear side frame of the right U-shaped frame; the left U-shaped frame The U-shaped frame is embedded in the steel left box body, a pair of left box body top bolt through holes are arranged on the top plate of the left box body, and a pair of left box body side panel bolt through holes are correspondingly arranged on the front side vertical plate and the rear side vertical plate of the left box body; the right U-shaped frame is embedded in the steel right box body, a pair of right box body top bolt through holes are arranged on the top plate of the right box body, and a pair of right box body side panel bolt through holes are correspondingly arranged on the front side vertical plate and the rear side vertical plate of the right box body; a connecting steel plate is fixedly connected between the rear side vertical plate of the left box body and the rear side vertical plate of the right box body, and the steel left box body and the steel right box body are fixedly connected. The side box body and the connecting steel plate form an integral frame covering the end of the drag chain; a transverse connecting bolt is arranged between a pair of connecting screw holes on the left frame side frames and a pair of bolt passing holes on the left box body side plates, and another transverse connecting bolt is arranged between a pair of connecting screw holes on the right frame side frames and a pair of bolt passing holes on the right box body side plates; a longitudinal connecting bolt is arranged between a pair of left side screw holes of the connecting plates, a pair of bolt passing holes at the top end of the left box body and a pair of connecting screw holes at the top end of the left frame, and another longitudinal connecting bolt is arranged between a pair of right side screw holes of the connecting plates, a pair of bolt passing holes at the top end of the right box body and a pair of connecting screw holes at the top end of the right frame.

[0006] The drag chain joint at the end of the drag chain of the present invention is completely covered by a U-shaped steel cover and then fixedly connected to the frame of the stacker. When the stacker works in a low-temperature environment of a cold storage, the drag chain joint becomes brittle at low temperature. The U-shaped steel cover on the drag chain joint transmits the unbalanced force of the drag chain joint to the drag chain joint, which is directly transmitted to the drag chain fixing bracket through the U-shaped steel cover, thereby protecting the plastic drag chain joint from breaking at the connection position.
