Gap between two tracks of double-rail beam 2, the gap between two tracks of the second double-rail beam 3 reach the second double-rail beam 3
Lower section.So set, being not only located at dregs transportation belt feeder 1 on the inside of two tracks of the first double-rail beam 2 and being located at the
On the inside of two tracks of two double-rail beams 3, installation space is saved to greatest extent, the first double-rail beam 2 and the second double-rail beam 3 will not
Interfere dregs transportation belt feeder 1, rationally distributed, installation and maintenance are convenient.
Connecting rod 11, the top of connecting rod 11 are connected between the tail end of first double-rail beam 2 and the head end of the second double-rail beam 3
Inclined reinforcing rib 12 is connected between the head end of the second double-rail beam 3, the setting of connecting rod 11 and reinforcing rib 12 is so that entirety
Structure is more stable.
The course of work of the invention:
First double-rail beam 2 and the second double-rail beam 3 are located between rear mating first section trolley and duct piece assembling machine walking beam, and first
The head end of double-rail beam 2 is connect with rear mating first section trolley, and the tail end of the second double-rail beam 3 is connect with duct piece assembling machine walking beam.Work
When making, the first electric block 41 and the second electric block 42 in the first double-rail beam 2 move to the top of segment car 5, and suspender 44 is hung
Section of jurisdiction 6 is played, then, the first electric block 41 and the second electric block 42 in the first double-rail beam 2 run to 2 He of the first double-rail beam
The overlapping of second double-rail beam 3, puts down section of jurisdiction 6.The first electric block 41 and the second electric block 42 in second double-rail beam 3 open
Dynamic, suspender 44 slings section of jurisdiction 6, and section of jurisdiction 6 is delivered to by the first electric block 41 and the second electric block 42 in the second double-rail beam 3
The lower section of duct piece assembling machine.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
