Abstract

The utility model discloses a pull rod for the balance arm of a flat-top tower crane. The pull rod for the balance arm of the flat-top tower crane comprises a front balance arm section (5) and a back balance arm section (6). The front balance arm section (5) and the back balance arm section (6) are connected in a hinging manner; a front pull rod (4) is arranged between the front balance arm section (5) and a tower; a support rod (2) is arranged at the hinged joint between the front balance arm section (5) and the back balance arm section (6); a horizontal pull rod (3) is arranged between the support rod (2) and the tower; and a back pull rod (1) is arranged between the back balance arm section (6) and the support rod (2). The pull rod for the balance arm of the flat-top tower crane has the advantages that the stress of the balance arm and the pull rod for the balance arm are reasonable, and the installation is convenient.

Description

Tack tower machine equilibrium arm pull bar
Technical field
The utility model relates to a kind of tack tower machine, particularly relates to a kind of tack tower machine equilibrium arm pull bar.
Background technology
Overall fixed connects between the equilibrium arm forearm of tack tower machine joint and the equilibrium arm postbrachium joint at present, and pull bar sockets on equilibrium arm postbrachium joint, and pull bar is stressed big, and pull bar is from great; Captive joint between equilibrium arm forearm joint and the equilibrium arm postbrachium joint needs integral hoisting, and erecting equipment is big, and particularly large-scale tack tower machine is installed difficulty.
The utility model content
Technical problem to be solved in the utility model provides a kind of equilibrium arm and the stressed tack tower machine equilibrium arm pull bar reasonable, easy for installation of balance arm brace.
In order to solve the problems of the technologies described above, the tack tower machine equilibrium arm pull bar that the utility model provides, comprise equilibrium arm forearm joint and equilibrium arm postbrachium joint, be articulated and connected between described equilibrium arm forearm joint and the equilibrium arm postbrachium joint, be provided with front tension bar between described equilibrium arm forearm joint and the pylon, on the hinge-point between equilibrium arm forearm joint and the equilibrium arm postbrachium joint, be provided with strut, be provided with the horizontal drawing bar between described strut and the pylon, be provided with back stay between described equilibrium arm postbrachium joint and the described strut.
Adopt the tack tower machine equilibrium arm pull bar of technique scheme, equilibrium arm, equilibrium arm pull bar are stressed more reasonable, and pull bar is stressed rationally, and the pull bar deadweight is little; Be articulated and connected between equilibrium arm forearm joint and the equilibrium arm postbrachium joint, the equilibrium arm pull bar adopts the girder structure, and two joint equilibrium arms are installed separately, and erecting equipment requires low, more economical, installs simple and convenient.
In sum, the utility model is the stressed tack tower machine equilibrium arm pull bar reasonable, easy for installation of a kind of equilibrium arm and balance arm brace.
Description of drawings
Fig. 1 is original tack tower machine equilibrium arm Tiebar structure scheme drawing;
Fig. 2 is a tack tower machine equilibrium arm Tiebar structure scheme drawing of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 2, be articulated and connected between equilibrium arm forearm joint 5 and the equilibrium arm postbrachium joint 6, be provided with front tension bar 4 between equilibrium arm forearm joint 5 and the pylon, on the hinge-point between equilibrium arm forearm joint 5 and the equilibrium arm postbrachium joint 6, be provided with strut 2, be provided with horizontal drawing bar 3 between strut 2 and the pylon, be provided with back stay 1 between equilibrium arm postbrachium joint 6 and the strut 2.
Referring to Fig. 1 and Fig. 2, equilibrium arm forearm joint 5 and equilibrium arm postbrachium joint 6, horizontal drawing bar 3, front tension bar 4 and back stay 1 are stressed more reasonable, and horizontal drawing bar 3, front tension bar 4 and back stay 1 deadweight are little; Be articulated and connected between equilibrium arm forearm joint 5 and the equilibrium arm postbrachium joint 6, the horizontal drawing bar 3 of equilibrium arm, front tension bar 4 and back stay 1 adopt the girder structure, and two joint equilibrium arm forearm joints 5 and equilibrium arm postbrachium joint 6 are installed separately, and erecting equipment requires low, more economical, install simple and convenient.
