A tower crane standard section movable connection structure

Abstract

The present invention discloses a movable connection structure for a standard section of a tower crane, comprising a main body, a connecting mechanism, and an oil delivery mechanism. The top of the main body is provided with a return groove, and the bottom of the main body is provided with a return block; wherein the connecting mechanism includes four lower connecting blocks located at the four corners of the bottom end of the main body. The present invention provides lower connecting blocks, upper connecting blocks, oblique blocks, transverse springs, and connecting grooves, inserting the return block of one main body into the return groove of another main body, and inserting the T-block located at the upper main body into the connecting groove of the lower main body. After the T-block enters the connecting groove, it squeezes the oblique block, thereby causing the oblique block to squeeze the transverse spring into the slot. The T-block contacts the bottom end of the connecting groove, releases the oblique block, and the elastic potential energy of the transverse spring does work, ejecting the oblique block, and tightly clamping the T-block in the connecting groove, thereby completing a fast, efficient, and stable connection between the main body and the other main body.

[0036] Working principle: First, before the device is put into operation, the return block 12 at the bottom of one main body 1 is inserted into the return groove 11 at the top of the other main body 1. At the same time, the T-block 3 located at the upper main body 1 is inserted into the connecting groove 5 of the lower main body 1. After the T-block 3 enters the connecting groove 5, it squeezes the oblique block 10, and the oblique block 10 squeezes the transverse spring 9 and retracts it into the card slot 7. The T-block 3 contacts the bottom end of the connecting groove 5, and the T-block 3 releases the inclined block 10. The elastic potential energy of the transverse spring 9 does work, pops out the inclined block 10, and tightly engages the T-block 3 in the connecting groove 5, thereby completing a fast, efficient and stable connection between the main body 1 and another main body 1. When disassembly is required, it is only necessary to dial the card shaft 6 outward so that the inclined block 10 compresses the transverse spring 9 and then retracts into the card slot 7 to release the engaged T-block 3, so that the main body 1 located above can be easily raised. When the tower crane operator climbs up and down the tower crane every day and steps on the spring block 16, the spring block 16 compresses the vertical spring 19, and the spring block 16 moves downward, thereby squeezing the rod 20 downward to squeeze the air bag 22, so that the lubricating oil in the air bag 22 flows into the return groove 11 through the oil pipe 17, and the return groove 11 is lubricated and rust-proofed.
