Abstract
Provided is a tower crane with an improved structure. A base section above (17) is arranged above a base (16), a standard section above (15) is arranged above the base section above (17), the standard section above (17) is positioned in a climbing stock (14), a lower support (21) is arranged above the standard section above (15), a rotary bearing (24) is arranged above the lower support (21), an upper support is arranged above the rotary bearing (24), and a rotary tower body (23) is arranged above the upper support (20). A tower top (4) is positioned above the rotary tower body (23), a cargo boom (9) is arranged on the right side of the rotary tower body (23), a balance arm (1) is arranged on the left of the rotary tower body (23), one end of a cargo boom pull rod (8) is arranged above an upper chord of the cargo boom (9), and the other end of the cargo boom pull rod (8) is arranged above the right of the tower top (4). One end of a balance arm pull rod (3) is arranged above a lifting point of the balance arm (1), and the other end of the balance arm pull rod (3) is arranged above the left of the tower top (4). A lift mechanism (2) is arranged above the balance arm (1), a jib lubbing mechanism (10) is arranged in the cargo boom, a rotary mechanism (22) is arranged above the upper support (20), a force moment limiter (5) is arranged under the left of the tower top (4), and a weight limiter (13) is arranged in the upper portion of the rotary tower body (23). The base section (17), the standard section (15) and a main chord of the metal structure of the improved structure tower crane are made of Q345 materials, and auxiliary rod members are made of Q235 materials. The tower crane with the improved structure can be applied to an 80 series tower crane. If each tower crane chooses intermediate value, steel materials can be saved by about 5%.
Description
One, technical field
The tower crane of optimizing structure is used for building sites such as building, water conservancy, electric power, highway, station, harbour, petrochemical industry, nuclear station to be used.
Two, background technology
Existing tower crane metal construction material all is Q235.Do tower crane metal construction weight with the material of Q235 and expend steel greatly, tower crane foundation joint, standard knot are not optimized.
Three, utility model content
The tower crane metal construction of optimizing structure is: base section, standard knot.
The purpose of the utility model is a kind of tower crane of optimizing structure that is suitable for of design.After tower machine concrete foundation reaches set strength, it is characterized in that: base section is on the basis, and standard knot is on base section; Standard knot is in the climbing frame the inside, and undersetting is on standard knot, and pivoting support is on undersetting; Upper bracket is on pivoting support, and slewing tower is on upper bracket, and cat head is on slewing tower; Crane arm is face on the right of slewing tower, and equilibrium arm is on the left side of slewing tower, and crane arm pull bar one end is on the crane arm top boom; Crane arm pull bar one end is the right on cat head, and equilibrium arm pull bar one end is end left side on cat head on the equilibrium arm suspension centre.Lifting mechanism is on equilibrium arm; Luffing mechanism is in the crane arm the inside, and swing type mechanism is on upper bracket, and limiter of moment is at the cat head left lower side; The weight limits device is in the inside on slewing tower top; The base section of the tower crane metal construction of optimizing structure, standard knot main chord material are Q345, and auxiliary bar is the Q235 material, and the tower crane of optimizing structure connects with bearing pin, high strength bolt pair, spring cotter, high strength nut.
Here the main 80 tower machine structured datas that use on the tower crane of optimizing structure of explaining; Optimize structure standard knot, base section, pivoting support, the frame that climbs, slewing tower, crane arm, equilibrium arm and crane arm pull bar, equilibrium arm on the tower crane, the high sizes of length and width such as upper bracket, undersetting, cat head will diminish 3%～13%.
The utility model is compared with known technology, and the main chord material of base section, standard knot is Q345, and auxiliary bar is the Q235 material.The utility model is used on the 80 serial tower machines, gets intermediate value for every and can practice thrift the steel about 5%.
