Abstract
The utility model discloses an extractable tower crane adhesion rod. According to the tower crane adhesion rod, adhesion rods are connected with a building and an adhesion frame; adhesion ear plates used for being connected with the adhesion rods are fixed on the building and the adhesion frame; each adhesion rod comprises a sleeve formed by welding two opposite channel steels; a rectangular rod piece formed by welding two opposite angle steels is arranged inside the sleeve; one end part, along the sleeve, of the rectangular rod piece extends outwards; the rectangular rod piece is welded and fixed with the sleeve; connection holes, used for being connected with the adhesion ear plates, are formed in the extending end part of the rectangular rod piece and in the sleeve positioned at the other end of the adhesion rod. The tower crane adhesion rod adopts a manner different from the prior art to regulate the length, utilizes the structural strength of the channel steels and the angle steels to form the sleeve and the rectangular rod piece by welding and fixing; the extending length of the rectangular rod piece is adopted to adapt to the length requirements during the mounting process; meanwhile, the tensile strength and the torsional strength are greatly improved.
Description
Technical field
The utility model relates to the Anchored Bar for fixed tower machine, and especially a kind of drawing and pulling type regulates the Anchored Bar of length.
?
Background technology
Tower crane, is widely used in the construction projects such as industrial premises, power station, bridge, civil construction.In work progress, tower crane is along with building constantly increases, in the time highly exceeding certain altitude, for guaranteeing tower crane resistance to overturning, must couple together with near building, make tower crane depend on (abbreviation adheres to or attached wall) on building.
Conventional attaching structure as shown in Figure 1, adheres on frame 3 fixed towers, adheres to frame 3 and adheres on pull bar 3 connecting building things 1 by 3 or 4; Wherein, adhere to pull bar 3 as shown in Figure 2, adhere to pull bar 3 and comprise bar body 8, in bar body 8, be provided with leading screw 7, rotating threaded shaft 7 can be controlled its extension elongation, and then regulates the entire length of adhering to pull bar 3, and clamp nut 9 is used for fixing the position of leading screw 7, the two ends of bar body 8 are provided with and connect square chest 6, connect square chest 6 and are connected with building 1 and the attaching lug 4 adhering on frame 3 by bolt 5.Regulate the length of adhering to pull bar 3 can eliminate the error of adhering to pull bar length and actual distance by leading screw 7, be convenient to adhere to the installation of pull bar.
But, while work due to tower machine, be 360 ° of rotations, causing adhering to the suffered load of pull bar is tension and compression alternations, and it is horizontally disposed adhering to pull bar, be subject to its effect of weight two ends to have moment of flexure, and leading screw is positioned at the two ends that moment of flexure is larger, cause leading screw alternating bending also will bear larger pressure simultaneously; In addition, threads of lead screw bottom also easily causes stress to concentrate.Above-mentioned these reasons cause adheres to easily generation endurance crack and difficult discovery of the long-term use of pull bar, once leading screw generation fracture will cause the even overall unstability of tower machine of adhesion failure, has potential safety hazard.

Utility model content
For adhering to the unsettled problem of Tiebar structure in prior art, the utility model provides a kind of drawing and pulling type tower machine Anchored Bar, this tower machine Anchored Bar adopts mode unlike the prior art to regulate length, utilize the structural strength of channel-section steel and angle steel self, form sleeve and square rod member by being welded and fixed, by the extension elongation of direction rod member, in the length requirement adapting in installation process, tension and torsion proof intensity promote greatly simultaneously.
To achieve these goals, the utility model drawing and pulling type tower machine Anchored Bar, described Anchored Bar connecting building thing with adhere to frame, described building with adhere to frame on be fixed with the attaching lug for being connected Anchored Bar, described Anchored Bar comprises by two sleeves that channel-section steel is welded in opposite directions, in described sleeve, be provided with the rectangle rod member being welded by two angle steel in opposite directions, described rectangle rod member stretches out along sleeve one end part, rectangle rod member and sleeve are welded and fixed, on the stretching out end and be positioned at the sleeve of the Anchored Bar other end of rectangle rod member, be provided with the connecting bore being connected with described attaching lug.
Further, the arranged outside of the described connecting bore on described rectangle rod member has brace panel.
Further, the inner side of the described connecting bore on described sleeve pipe is provided with brace panel.
Further, on described sleeve pipe, be provided with the batten plate that connects described channel-section steel.
The reliability of the utility model drawing and pulling type tower machine Anchored Bar improves, and reinforces Anchored Bar by brace panel and batten plate in the stressed general goal of crossing, and tower machine monolithic stability has also had Reliable guarantee, and result of use is good.

The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is elaborated.
As shown in Figure 3 and Figure 4, for the specific embodiment of the utility model drawing and pulling type tower machine Anchored Bar, in the present embodiment, Anchored Bar is for connecting building thing 1 and adhere to frame 3, and building 1 is all fixed with attaching lug 4 with adhering on frame 3, and Anchored Bar mainly comprises sleeve 11 and rectangle rod member 12, wherein, sleeve 11 is to be welded by two channel-section steels that arrange in opposite directions, is provided with the batten plate 10 that connects these two channel-section steels on sleeve pipe 11, and figure is shown in 4.Rectangle rod member 12 is arranged in sleeve 11, and stretches out along sleeve 11 one end parts, and rectangle rod member 12 is to have by two angle steel to be in opposite directions welded.In the time that drawing and pulling type tower machine Anchored Bar is installed, at the scene rectangle rod member 12 is adjusted to the length of matters, then by welding, rectangle rod member 12 and sleeve 11 are fixed, stretching out end and being positioned on the sleeve 11 of the drawing and pulling type tower machine Anchored Bar other end of rectangle rod member 12 is provided with connecting bore, bolt of rear end plate 5, through attaching lug 4 and connecting bore, is fixed the two ends of drawing and pulling type tower machine Anchored Bar.Bear compared with high pulling torque due to the two ends of drawing and pulling type tower machine Anchored Bar in use, therefore the arranged outside of the connecting bore on rectangle rod member 12 has brace panel 9, and the inner side of the connecting bore on sleeve pipe 11 is provided with brace panel 10.
Above-mentioned example is just for illustrating the utility model, and embodiment of the present utility model is not limited to these examples, and what those skilled in the art made meets the various specific embodiment of the utility model thought all within protection domain of the present utility model.
