Standard knot be connected on column foot by Extension support and hawser, so as to laterally increase the stress torque of tower crane, so as to effectively protect
The stability that card tower crane is used, improves the safety coefficient of tower crane.
Further, it is in series with the anti-breaking device for preventing hawser from breaking in hawser.By the design of anti-breaking device,
The anti-breaking device can be extended so as to alleviate the pulling force suffered by hawser when pulling force reaches certain value, improving hawser makes
Safety.
Further, anti-breaking device includes pull bar, fixed cover and breaks set, and fixed cover is set in outside pull bar and and pull bar
Gap is arranged, and pull bar is connected set by breaking set, breaks to cover and bears the pulling force of pull bar up to breaking set quilt prior to fixed cover
Break.The anti-breaking device, by the design for breaking set, makes device have an effect for breaking device, and while ensure not to be pulled off,
Ensure the Stabilization to tower crane.
Further, breaking set includes the first Access Division, breaks portion and the second Access Division；First Access Division and the second clamping
Cylinder lever connecting rod and fixed cover are distinguished by portion, and the portion of breaking is located between the first Access Division and the second Access Division.Break being designed to for portion
Make to break set with a weak link easily broken, be convenient to break the design for covering specified pull-off force.
Further, pull bar includes rod section, draw-in groove portion and connecting portion, breaks before set is broken in connecting portion and the second clamping
There is gap, draw-in groove portion is connected with the first Access Division, and the second Access Division is connected with fixed cover between portion or fixed cover,
The specified pull-off force in portion is broken less than the first Access Division and the second Access Division.Break and be provided with portion liquid chambers, first breaks portion
After breaking liquid in liquid chambers can flow out to outside fixed cover.The liquid chambers of the structure can be convenient to whether observation breaks set
It is pulled off.
In sum, as a result of above-mentioned technical proposal, the beneficial effects of the utility model are：
1. the standard knot of the structure is connected on column foot by Extension support and hawser, so as to laterally increase tower crane by force
Square, so as to effectively ensure the stability that tower crane is used, improves the safety coefficient of tower crane.
2. using the Extension support structure and cable structure of the standard knot, it is sequentially connected from top to bottom, forms connection column foot top
Portion and column foot and the pulling force circuit supported by Extension support, are making a concerted effort for pulling force then by being symmetrical in the pulling force circuit of standard knot
With the dead in line of standard knot, so as to increase the trimming moment of tower crane, stable tower crane.
