Description
Technical field
The utility model belongs to building implement field, particularly relates to a kind of tower crane sustaining wall expansion link.
Background technology
Tower crane is a kind of weight-lifting equipment the most frequently used on building ground, with a section spreading, as the form of a steel tower, be also tower crane, be used for hanging construction with the raw-material equipment of construction such as stupefied, the scaffold tubes of reinforcing bar, wood, be a kind of requisite equipment of building operation.And the safety problem of tower crane often will considered when designing tower crane, because general tower crane height is higher, and the cross section of its base portion is less thus likely cause toppling over of tower crane because foundation is unstable in actual use, generally sustaining wall device can be installed on tower crane now, sustaining wall device by the sustaining wall frame that is enclosed within tower body and the sustaining wall arm that is connected between sustaining wall frame and building to reach stable, and like product in the market, major part be all determine size after the length of bamboo product processing sustaining wall arm, its setting range is little, the design and construction time is long, and when next time installs different size substantially, needs cut open, lengthen or shorten the length of sustaining wall arm, refuted by welding and connect, it is made to adapt to new workyard, and often process the fatigue resistance that sustaining wall arm can reduce sustaining wall arm, increase its fugitiveness, reduce safety.
Utility model content
The purpose of this utility model is to provide a kind of tower crane sustaining wall expansion link, be intended to solve existing tower crane sustaining wall arm can not telescopic adjustment or setting range little, different workyard needs to redesign, and installs and problem that transport is very inconvenient.
The utility model realizes like this, a kind of tower crane sustaining wall expansion link comprises sustaining wall frame, first telescopic boom, second telescopic boom, 3rd telescopic boom, 4th telescopic boom, four telescopic booms are hinged respectively and are connected on four angles of sustaining wall frame, four described telescopic booms are all be made up of the solid cylinder of hollow extra heavy pipe and the hollow extra heavy pipe of insertion, hollow extra heavy pipe is provided with multiple spiral to be staggered the aperture of 90 °, solid cylinder is provided with the multiple spirals corresponding with aperture on hollow extra heavy pipe to be staggered the aperture of 90 °, hollow extra heavy pipe and solid cylinder by taper pin in aperture place secure bond, hollow extra heavy pipe and solid cylinder joint are provided with and encircle anchor fitting, dimidiation, be screwed, solid cylinder and sustaining wall pedal are by bidirectional helical cylinder connection.
Further, the hollow extra heavy pipe of described telescopic boom adopts seamless thick walled steel tube.
Further, the first described telescopic boom, the second telescopic boom, the 3rd telescopic boom, the 4th telescopic arm structure are identical, first telescopic boom is the same with the 4th telescopic boom length, and the second telescopic boom is the same with the 3rd telescopic boom length, and the first telescopic boom length is longer than the second telescopic boom.
The telescopic boom of tower crane sustaining wall expansion link of the present utility model can regulate the position of aperture on hollow extra heavy pipe and solid cylinder to regulate telescopic boom adjustable length according to Len req, and telescopic boom adopts seamless thick walled steel tube, and be out of shape little, telescopic extensions is large.
