Trimming moment, so as to improve tower crane stability in use, it is ensured that the security that equipment is used, the versatility of the structure
Good with generalization, its easy installation and removal can make the stability of tower crane by increasing the length of Extension support.
Further, multiple Extension supports are set side by side with tower body, Extension support is fixedly connected and supporting cable with hawser respectively
Rope, Extension support is hinged with tower body.By time delay frame, the globality of hawser stabilization advantageously in the transmission of pulling force can be improved,
Stable tower body structure that can be section by section, improves the stability of tower body.
Further, the length of Extension support is 1-1.5 times of tower body width, and extends the outside handed over and be hinged on tower body；Hawser
It it is 1.3-3 times of tower body width with the distance of the tie point of column foot to tower body axis.The choosing of the link position and Extension support length
Select and ensure that Extension support can preferably extend the horizontal torque of standard knot, it is ensured that tower body stability of equilibrium.
Further, hawser protector is provided with hawser, hawser protector is used to detect whether drawstring exceedes specified drawing
Power.By hawser protector, it is prevented from hawser and breaks the potential safety hazard for causing.
Further, hawser protector includes housing, the first connector, the second connector and breaks part, the first connector with
Second connector is connected by breaking part, and housing is set in be broken part and the first connector, the second connector and break outside part,
When breaking after part is pulled off the pulling force that is born by housing between the first connector and the second connector.Hawser protector hawser is used
Security, before pulling force is reached the specified pull-off force of drawstring, first break this and break part, thus effectively observe hawser whether
Excess load is used, and then improves the protection feature of hawser.
Further, cushion chamber is provided between the first connector or the second connector and housing, on the side wall of cushion chamber
It is communicated with the pore of hull outside；Breaking after part is pulled off, the first connector or the second connector extruding cushion chamber make to delay
Rush chamber discharge opeing or exhaust.Cushion chamber can be by the pulling force between certain displacement reduction hawser, so as to reduce instantaneous pulling force pair
The damage of equipment.
Further, first connector includes drag link end and connection end, and connection end has the draw-in groove of lateral openings, draw-in groove
For breaking part clamping, the opening of draw-in groove is used to break the dismounting of part, and drag link end one end is connected with connection end, the other end is through simultaneously
Stretch out housing；First connector is identical with the second connecting-piece structure.The design that the structure passes through draw-in groove, now can break the fast of part
Speed is replaced, and can be realized Fast Installation and be used.
In sum, by adopting the above-described technical solution, the beneficial effects of the utility model are：
1. the tower crane of the structure can increase tower crane trimming moment in the horizontal direction by hawser, so as to improve tower crane exist
Stability during use, it is ensured that the security that equipment is used, the versatility and generalization of the structure is good, its installing/dismounting side
Just, the stability of tower crane can be made by increasing the length of Extension support.
2., by the setting of hawser protector, it is prevented from hawser and causes internal break to leave hidden danger under compared with strong pulling force,
Potential safety hazard on hawser can be shown by breaking device, place steel cable and break the harm for causing.
