Description
Technical field
The utility model belongs to suspender, especially relates to a kind of suspender of steel purlin bar.
Background technology
In the steel-structure factory building work progress, there is a large amount of steel members to lift, especially the roofing part, the quantity of steel purlin bar is many, and the lifting of steel purlin bar at present is after using the steel rope binding, to winch to roofing with crane mostly, after preliminary fixing, then steel rope is untied; But this method is in binding and equal more time-consuming, effort when untiing steel rope, and because there is elastic force in steel rope itself, can not the binding of steel purlin bar is solid, slip phenomenon easily occurs in the steel purlin bar in the lifting process, has potential safety hazard.
Summary of the invention
The purpose of this utility model is to propose a kind of lifting steel purlin bar clamp, and is not only simple in structure, easy to use and reliable, and clamping steel purlin bar securely, further eliminates safe hidden trouble.
the purpose of this utility model is achieved like this: a kind of lifting steel purlin bar clamp (abbreviation clamp), it is characterized in that: this lifting steel purlin bar with clamp mainly by left grip block, right grip block, spring perch, Compress Spring, screw rod and nut form, this left grip block, the structure of right grip block is identical but arrange in opposite directions, the epimere of this left grip block is cuboid and towards the upper left side to tiltedly stretching, the hypomere of this left grip block is the reverse C shape plate that is vertical setting, the epimere of this right grip block is cuboid and towards the upper right side to tiltedly stretching, the hypomere of this right grip block is the C shape plate that is vertical setting, the middle part of left grip block and right grip block is the front and back juxtaposition, and offer sagittal bolt hole this cross-lapping department is corresponding respectively on left grip block and right grip block, install screw rod and be screwed nut in this bolt hole, form the radial type clamp, at left grip block, offer respectively symmetrically the hole of restricting on the upper end section of right grip block, simultaneously, at left grip block, cylindrical spring seat symmetrically is welded respectively on the middle part medial surface of the cuboid section of right grip block, between this left and right cylindrical spring seat, Compress Spring is installed, the length of the cuboid section of this left grip block, right grip block * wide * thick 400-500mm * 30-40mm * 10mm that all can be, the length of the C shape plate of the reverse C shape plate of this left grip block, right grip block * wide * thick 300-400mm * 30-40mm * 10mm that all can be.
During use, penetrate respectively the steel rope of lifting use in rope hole, left and right, with steel rope, this clamp is hung on the hoisting crane hook, inwardly push the left grip block of this clamp and the upper end section of right grip block with two hands, the lower end jaw of this clamp will be opened, the steel purlin bar that will lift is installed on this jaw, unclamp hand, under the pressure-acting of Compress Spring, jaw closes up, and clamp the steel purlin bar, with hoisting crane, the steel purlin bar is sling.After lifting puts in place, inwardly push the left grip block of this clamp and the upper end section of right grip block with two hands, the lower end jaw of this clamp will be opened, and takes off this clamp, and is to lift next steel purlin bar, easy to use safe and reliable again.
The lifting steel purlin bar clamp that the utility model proposes, not only simple in structure, easy to use and reliable, and also clamping steel purlin bar securely, time saving and energy saving, improved work efficiency, further eliminated potential safety hazard.
The lifting steel purlin bar that now in conjunction with the accompanying drawings and embodiments the utility model is proposed is described further with clamp.
