Description
Technical field
The present invention relates to construction equipment fields, and in particular to a kind of adaptive counterweight tower crane.
Background technique
Tower crane is a kind of equipment indispensable in engineering construction, for hanging working reinforcing bar, wooden flute, concrete, steel
The raw material of the constructions such as pipe can greatly improve project progress and efficiency when building high building, but tower crane is lifted in lifting
Weight is often reduced with the lengthening of the length of crane arm, due to current tower crane balance weight set on counter-jib
To be fixed, therefore no matter in lifting or non-lifting, the balance weight gesture of the counter-jib cooperation fixed weight of the fixed arm of force
The rotating disk mechanism of tower crane must be impacted, due to the imbalance of the arm of force, be easy to further result in pylon bending or even collapse
The case where occur, it is especially serious that tower crane topples over accident, often will cause personal injury and property loss, tower crane accident is in construction thing
Therefore middle proportion is growing day by day, seriously jeopardizes the life security of construction personnel, therefore how to effectively control tower crane counter-jib with
Between crane arm pros and cons balance, reduce pylon bending, while improve tower crane crane arm end bearing capacity just at one urgently
Technical problem to be solved.
Summary of the invention
Based on the above issues, it is an object of that present invention to provide a kind of bearing capacity is strong, when unloaded pylon bending degree it is small and
The adaptive counterweight tower crane of weight between counter-jib and crane arm can be balanced according to practical hoisting weight.
In view of the above problems, providing following technical solution: a kind of adaptive counterweight tower crane, including pylon, be located at pylon
The rotating disk mechanism on top, the rotating disk mechanism is equipped with the counter-jib and crane arm that rotation can be driven by rotating disk mechanism, described
Counter-jib and crane arm are arranged in 180 degree each other in the circumferential direction of rotating disk mechanism, and the counter-jib is equipped with clump weight, institute
It states and is additionally provided with control room on rotating disk mechanism, the counter-jib is hinged towards one end of rotating disk mechanism and rotating disk mechanism, makes counter-jib
Realize and swing up and down that the clump weight is located at the one end of counter-jib far from rotating disk mechanism in one end far from rotating disk mechanism;Described turn
Tower crane point is additionally provided on disc mechanism, there is for controlling balance arm swing, to change oblique pull between the tower crane point and counter-jib
Clump weight to rotating disk mechanism arm of force distance drawing cable mechanism.
In above structure, controlled using the counter-jib that can be swung up and down clump weight to the arm of force between rotating disk mechanism away from
From the purpose of realization adjustment arm strength arm lengths can be controlled in unloaded and load by adjustment arm strength arm lengths
Load balance on crane arm reduces rotating disk mechanism and undertakes unbalanced load, improves rotating disk mechanism integrated carrying ability, prolong
Long rotating disk mechanism service life, and effectively reduce causes pylon bending inclined because gravity is inconsistent between counter-jib and crane arm
