Abstract
The utility model discloses a steel pipe gantry frame and is characterized in that four columns are formed by multi-segment steel pipe frames shaped like a Chinese character 'jing' which are inserting to and arranged on each other, wherein guiding positioning steel pipes provided with annular spacer rings are inserted in and arranged on stand pipes which are corresponding to each upper and lower segment frames shaped like a Chinese character 'jing', adjacent transverse pipes are closely connected with each other by U-shaped bolts, an electric motor is arranged on a top rail of a nacelle of which a left side and a right side are evenly provided with telescopic positioning pins which are made by springs or the electric motor and traction wire ropes to extend out or shrink in order to realize the high attitude positioning and positioning disengagement of the nacelle, thereby the steel pipe gantry frame has the advantages of quick and convenient erection and safe and reliable operations; moreover the utility model does not make noises during the process of the high attitude positioning.
Description
The utility model is a kind of improved building operation portal frame.
Existing building ground portal frame commonly used, its four intersecting parallels columns are to assemble face with the intersecting parallels framework that more piece is welded into by angle steel, coupling method commonly used is a boring bolted connection on horizontal angle steel, and the status requirement to the size of each screw and adjacent screw is tighter like this.In case angle steel distortion or eyelet processing dislocation connect very difficultly by load, will have influence on the squareness and the stability of portal frame, it is snap-in that the location after the hanging basket of existing portal frame raises in addition adopts radius stay to force usually, and noise is very big.
The purpose of this utility model is a kind of steel pipe portal frame of design, its column assembles with the intersecting parallels framework of more piece by the steel pipe welding, but assembling mode is a plug-in type, but location, the high-altitude of hanging basket adopts the locating dowel pin of elastic telescopic to realize, like this, portal frame sets up convenient, flexible at the construction field (site), hanging basket location noiselessness and safe and reliable.
The purpose of this utility model is achieved like this:
Four intersecting parallels columns of portal frame assemble by joint with more piece intersecting parallels steel framework, the guide-localization steel pipe of a band shape of plug-in mounting spacer ring in the relative vertical standpipe of every two joint intersecting parallels frameworks up and down, the adjacent horizontal steel pipe of every two joint intersecting parallels frameworks up and down is tightly fixing with U-bolt, like this a joint joint intersecting parallels framework is connected into the height of intersecting parallels column up to needs by joint; Adorn an electrical motor on the entablatrance of this external hanging basket, respectively adorn two telescopic locating dowel pins about electrical motor, locating dowel pin is stretched out or shrink by spring or electrical motor and traction steel rope of cable, realize that the location, high-altitude and the location of hanging basket breaks away from, not only noiselessness but also safe and reliable.The utility model is simple in structure, easy for installation and safe and reliable.
Now in conjunction with the accompanying drawings the utility model being carried the steel pipe portal frame is further described:
Fig. 1 is the scheme drawing that the utility model is carried the steel pipe portal frame.
Fig. 2 is the birds-eye view of intersecting parallels column.
From Fig. 1, among Fig. 2 as can be seen, the steel pipe portal frame is mainly by four intersecting parallels columns 1, hanging basket 2, column head piece 3, elevator pulley 7, hanging basket pulley 5, main rope 6 compositions such as grade, it is characterized in that each intersecting parallels column 1 is assembled by more piece intersecting parallels steel framework, each intersecting parallels steel framework is by four standpipes 15, eight transverse tubes 13,14 (with dashed lines circle expression among Fig. 1) welding is made, four standpipe 15 upright putting into square are arranged, (Fig. 2) upper and lower side that forms two standpipes 15 of each vertical surface welds two parallel horizontal transverse tubes 14 or 13, up and down all insert a positioning and guiding steel pipe 17 in the intersecting parallels framework standpipe 15 in correspondence with each other in each of column 1, the stage casing periphery of positioning and guiding steel pipe 17 is adorned annular spacer ring 18, join together with plug welding 19 between positioning and guiding steel pipe 17 and the annular spacer ring 18, fall down to guarantee that positioning and guiding steel pipe 17 does not come off, in addition, the adjacent transverse tube 14 or 13 of intersecting parallels steel framework all couples together tightly with U-bolt 16 about each.Four of the steel pipe portal frame principal posts 1 just erect rapidly reliably like this, medium position is adorned the electrical motor 8 of a belt leather belt wheel on the entablatrance of hanging basket 2, and the right and left on the entablatrance of hanging basket 2 respectively installs 2 registration devices 4 with bolt symmetrically, registration device 4 is by stub 12, spring 10, sleeve 11 compositions such as grade, stub 12 is extended sleeve 11 under the effect of spring 10, link to each other with traction steel rope of cable 9 between the belt pulley of stub 12 and electrical motor 8, when the operator rotates the lifting winch (not drawing among the figure) of hanging basket 2, the height of the needs that steel rope 6 promotes hanging basket by pulley 7 and 5, at this moment, unclamp motor 8, a left side, spring 10 elongations in the right registration device 4, stub 12 pushed away stretch out sleeve 11, frame is on the horizontal steel pipe 14 of left and right pillar 1, hanging basket 2 is aerial with regard to be parked in steadyly, when hanging basket 2 needs to descend, as long as rotating motor 8, belt pulley traction steel rope of cable 9 pulling stubs 12 overcome spring 10 elastic pressure and in the indentation sleeve 11, rotate lifting winch, hanging basket is put down, not only noiselessness but also safe and reliable.
Claims (1)
