Description
Technical field
The present invention relates to a kind of building operations scaffold, particularly relate to the antitorque connecting pin hand cradle of a kind of pin.
Background technology
Existing scaffold comprises vertical rod with cross bar and for the above two being connected temporary fixed fastener together, and the present inventor finds in long-term building operations uses: this scaffold exists complex structure, is inconvenient to the problem used.
Summary of the invention
The object of the invention is the above-mentioned defect overcoming prior art, provides a kind of structure simple, the antitorque connecting pin hand cradle of pin easy to use.
For achieving the above object, the antitorque connecting pin hand cradle of pin of the present invention comprises the horizontal cross bar of vertical rod and snapping with it, its special feature is that described vertical rod has the four eyed disc type plug housing of multiple equidirectional configuration between the upper and lower every solid welding, and described four eyed disc type plug housing is shaped with four equally distributed cone pin eyes of circumference; Described horizontal cross bar two ends solid welding has antitorque fork, and described antitorque fork upper front end or front end face and bottom are shaped with the arc-shaped notch that match convex in described vertical rod periphery arc and the tapered spigot with the inserting of described cone pin eye respectively.Design like this, as long as the cone pin eye tapered spigot of antitorque for yardarm fork being inserted vertical rod tapered spigot can complete is connected and fixed, and disassembles as long as taken out to complete from the cone pin eye of vertical rod tapered spigot by the tapered spigot of antitorque for yardarm fork.And cone pin eye i.e. easy disassembly but also have stronger compressive strength.With therefore, it is simple that it has structure, easy to use, the advantage that compressive strength is high.
As optimization, described vertical rod lower end periphery is welded with the splicing sleeve of a specification larger than vertical rod self; Described cone pin eye is cut a part of rounding by cylindrical vertical rod to lack taper type hole.Vertical rod lower end is welded with the sleeve pipe of a specification larger than vertical rod, and during to ensure vertical rod spreading, axle center on one wire, not eccentric.
As optimization, this splicing sleeve accounts for the in-built vertical rod in top of self total length about 2/5, and the bottom accounting for total length 3/5 is grafting space; Described rounding lacks taper type hole size and accounts for and cut about 3/5 of rounding frustum hole.
As optimization, described antitorque fork hollow.Fork adopts design on an empty stomach, alleviates accessory weight, reduces cost.Fork adopts design on an empty stomach, reduces fork bending rigidity, ensures that plug housing does not damage under fork bending resistance breaking state.Described four eyed disc type plug housing is that plug housing is widened in thickening.Plug housing adopts and thickeies Widening Design, fork limit stress destruction when ensureing that fork and plug housing work and plug housing is indeformable.
As optimization, described antitorque fork is described horizontal cross bar end solid welding inner sleeve tube head, and described inner sleeve tube head is shaped with the tapered spigot with the inserting of cone pin eye downwards, and described inner sleeve tube head front end face is shaped with and the convex arc-shaped notch matched of described vertical rod periphery arc; Described hollow be inner sleeve tube head level to hollow, the vertical hollow of described tapered spigot.
As optimization, described inner sleeve tube head level is uncovered in front and back end to hollow; Described tapered spigot is shaped with the vertical cavity of up big and down small taper.Very convenient like this manufacture, namely uses the steel pipe of limited several specification just all can produce standardization cross bar and annex and vertical rod and annex, facilitates production line balance.
As optimization, described antitorque fork hollow is that described antitorque fork is shaped with the horizontal cavity laterally run through and the perpendicular cavity vertically run through.Accessory weight can be alleviated further, reduce cost, and convenient manufacture.
As optimization, described cone pin eye has two or more side, at least one side is the up big and down small conical surface, the conical surface described in one or more is shaped with radial line shallow slot or fin, is shaped with corresponding identical radial line small convex rib or groove with it with the tapered spigot of described cone pin eye inserting.Like this, cunning or slippage is prevented after installation.Described radial line shallow slot or fin and the with it corresponding radial line small convex rib that coincide or groove are vertical distribution or cross direction profiles or diagonally distribute or any combination of aforementioned three kinds of distribution modes.
As optimization, the outer rim that described cone pin eye is relative with vertical rod and the corresponding with it inner circumferential of described tapered spigot are the circular arc conical surface, and described radial line shallow slot and described radial line small convex rib are prepared in described circular arc outer rim and circular arc inner circumferential.Described radial line shallow slot and described radial line small convex rib are all vertical distribution.Preferred described tapered spigot is from top to bottom tapered or described tapered spigot outer face from top to bottom slopes inwardly gradually.
As optimization, described vertical rod wall thickness is 3.6mm, and horizontal cross bar length is respectively 450; 600; 750; 900; 1200; 1500; 1800; 2100; 2400mm; Wherein 450,600, the long employing wall thickness of 750mm is 2.75mm steel pipe, 900,1200, the long employing wall thickness 3.0mm steel pipe of 1500mm, 1800,2100, the long employing wall thickness 3.2mm steel pipe of 2400mm;
The transverse width of described antitorque fork to be narrowed or the diameter of described antitorque fork is diminished to front gradually by rear to front gradually by rear.Like this, occupy little space, very convenient dismounting.
Described antitorque fork upper front end and bottom are shaped with the arc-shaped notch that match convex in described vertical rod periphery arc and the tapered spigot with the inserting of described cone pin eye respectively, and described tapered spigot front end face from top to bottom tilts backwards gradually, have the space widened gradually from top to bottom between described tapered spigot front end face and described vertical rod periphery; More convenient like this dismounting.
It is a four eyed disc type plug housing, is welded in vertical rod by certain spacing; Four eyed disc type plug housing welding direction should be consistent; The four eyed of four eyed disc type plug housing is 3/5 (falling) taper, and its conical surface has radial line shallow slot, protrudes little muscle coincide antitorque with latch; Vertical rod lower end is welded with the sleeve pipe of a specification larger than vertical rod, and during to ensure vertical rod spreading, axle center on one wire, not eccentric; Vertical rod adopts the wall thickness meeting national standard to be the scaffold special steel pipe of 3.6mm; Horizontal cross bar two end is welded with antitorque fork, and its fork feature is: lower taper body and plug housing are inserted to tie and coincide; Front end, top and vertical rod sidewall contact coincide; Upper rear end welds with horizontal cross bar; Fork center is on an empty stomach up and down; Fork upper rear end is loop configuration, and center is also on an empty stomach; There is radial small convex rib the external side of fork lower taper, and this small convex rib and the radial shallow slot of plug housing coincide; The little muscle that fork upper front end and vertical rod money side joint synapsis have several to protrude, this little muscle is the important measures ensureing to prevent after horizontal cross bar is installed cunning; Because fork have employed design on an empty stomach, alleviate accessory weight, reduce cost; Fork adopts design on an empty stomach, reduces fork bending rigidity, ensures that plug housing does not damage under fork bending resistance breaking state.Plug housing adopts and thickeies Widening Design, fork limit stress destruction when ensureing that fork and plug housing work and plug housing is indeformable.
After adopting technique scheme, it is simple that the antitorque connecting pin hand cradle of pin of the present invention has structure, and easy to use, compressive strength is high, not fragile, on-deformable advantage.
