Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, the present invention provides a technical solution:

the utility model provides a steering mechanism of tower crane, includes first bracing piece 1, and the top of first bracing piece 1 is provided with third bracing piece 3, has run through second bracing piece 2 in the third bracing piece 3, is provided with gear 7 between first bracing piece 1 and the third bracing piece 3, and the side of gear 7 is provided with a pair of supporting seat 4, is provided with threaded rod 5 in the supporting seat 4, and the side of supporting seat 4 is provided with driving motor 6, and the side of gear 7 is provided with brake equipment. The gear 7 is rotatably connected with the top of the first supporting rod 1, and the threaded rod 5 is meshed with the gear 7. Threaded rod 5 and supporting seat 4 rotate to be connected, driving motor 6's output and threaded rod 5 fixed connection. Brake equipment includes spacing groove 8, and the inside of spacing groove 8 is provided with spacing seat 10, and the one end inboard of spacing seat 10 and spacing groove 8 is provided with spring 9, and the top of spacing seat 10 is provided with cylinder 11, and the output of cylinder 11 is provided with limiting plate 12, and the side evenly distributed of limiting plate 12 has tooth 13.
