The utility model discloses a large tower crane which comprises a tower body, a rotary tower, a tower head and a crane jib, wherein the tower body is fixedly connected with the rotary tower, and the tower head is fixedly connected with the crane jib. The large tower crane is characterized in that the rotary tower and the tower head are formed into an integrated structure, a supporting wed member of the tower head is in a panel structure and in an A shape, and the crane jib is in an inverted triangle shape. Compared with the prior art, the large tower crane has the remarkable advantages of being compact in structure, high in fastness and bearing capacity, convenient to use and practical.
Description
Technical field
The utility model relates to a kind of large-scale tower crane.
Background technology
The tower crane of prior art supports web member and adopts leverage web member structure usually, causes the fastness of structure good inadequately, is difficult to lift by crane large-sized object.
The utility model content
Technical problem to be solved in the utility model is to overcome existing above-mentioned deficiency in the prior art, and a kind of simple for structure, fastness is big, load-carrying capacity is strong, convenient and practical large-scale tower crane is provided.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: this large-scale tower crane, comprise body of the tower, turret, tower head and arm, body of the tower is captiveed joint with turret, tower head is captiveed joint with arm, it is characterized in that turret and tower head adopt integrative-structure, it is plank frame that tower head supports web member.
It is the A font that tower head described in the utility model supports web member.
Arm described in the utility model adopts the inverted triangle structure.
The utility model compared with prior art has following positive effect: simple for structure, fastness is big, load-carrying capacity is strong, convenient and practical.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below with reference to Fig. 1, Fig. 2 the utility model embodiment is described.
Fig. 1 illustrates the structure of large-scale tower crane, comprise body of the tower 1, turret 2, tower head 3, arm 4, body of the tower 1 is captiveed joint with turret 2, turret 2 adopts integrative-structure with tower head 3, tower head 3 supports web member and adopts plank frame to replace leverage web member structure, whole plate face is huge " A " font, has strengthened the fastness of tower head 3; Tower head 3 is captiveed joint with arm 4, the structure that arm 4 adopts is the inverted triangle structure, top boom is a square steel, and lower boom is an I-beam section, and diagonal web member all is a steel pipe, straight web member is an angle steel, tower head 3 is connected hinge with arm 4 be a hexahedron structure frame, and this structure-steel framing adopts bearing pin to be connected with arm 4 top booms, is connected with lower boom and adopts bolted connection, this behavior of structure uniqueness has very big load-carrying capacity.Stressed being easy to of lower boom analyzed, and vehicle structure is simple, and bearing capacity is big, and the staff can walk in arm, and in some occasion, top boom becomes workplatform after can installing guardrail, has realized a tractor serves several purposes, is easy to more install, and is convenient and practical.
Allly conceive equivalence or the simple change that described structure, feature and principle are done, be included in the protection domain of the utility model patent according to the utility model patent.
