Abstract
The utility model relates to a connection structure, particularly relates to a connection structure for a tower roof of a tower crane and an upper support saddle. The connection structure comprises the top roof and a tower body, wherein the tower roof and the tower body are fixed through a connection rod; the tower roof comprises a main chord member; horizontal web members horizontally distributed are arranged in the main chord member; inclined web members which are obliquely distributed are arranged among the horizontal web members; the tower body comprises a tower body main chord member; tower body horizontal web members horizontally distributed are arranged in the tower body main chord member, and tower body inclined web members obliquely distributed are arranged among the tower body horizontal web members. According to the connection structure for the tower roof of the tower crane and the upper support saddle, the structure is simple; and the structure strength is improved, and the stability is also improved.
Description
Technical field
The utility model patent relates to a kind of connection structure, relates in particular to a kind of connection structure that is used for tower machine cat head and upper bracket.
Background technology
Original cat head structure is that slewing tower is to separate making with cat head in the prior art at present; Making every angle, back connects through a backing pin shaft; When having in the use cat head and stressed left, the time and receive force phenomenon to the right, cause pin hole to increase after the time is long; The generation junction is loosening, and shadow is to the stability of tower machine.
Each fillet welding of former slewing tower and upper bracket has two adapter sleeves; Slewing tower is connected the employing bolted connection with upper bracket; Because the tower machine is in use, the stressed after frequentation reciprocating cutter of slewing tower, tie bolt is easy to become flexible; Influence the stability of tower machine, and tighten comparatively trouble in case pine props up.
Summary of the invention
The utility model mainly is to solve the deficiency that exists in the prior art, provides a kind of simple in structure, and makes the stability-enhanced connection structure that is used for tower machine cat head and upper bracket of tower machine.
The above-mentioned technical matters of the utility model mainly is able to solve through following technical proposals:
A kind of connection structure that is used for tower machine cat head and upper bracket comprises cat head and body of the tower, and described cat head and body of the tower fix through pipe link; Described cat head comprises main chord; Be provided with the horizontal web member of horizontal distribution in the described main chord, be provided with the diagonal web member that diagonally distributes between described horizontal web member, described body of the tower comprises the body of the tower main chord; Be provided with the horizontal web member of body of the tower of horizontal distribution in the described body of the tower main chord, be provided with the body of the tower diagonal web member that diagonally distributes between the horizontal web member of described body of the tower.
The utility model is provided for the connection structure of tower machine cat head and upper bracket, and is simple in structure, improves structural strength, improves stability.
