Description of drawings
The structural representation of Fig. 1, a kind of building operations attaching scaffold of the utility model safety lifting device;
The A-A of Fig. 2, Fig. 1 is to sectional view.
The specific embodiment
A kind of building operations attaching scaffold of the utility model safety lifting device, the specific embodiment is:
As shown in the figure: a kind of building operations attaching scaffold safety lifting device comprises support 1, ricker 2, safety device; Attaching scaffold is built for skeleton by several rickers 2 that vertically arrange, ricker 2 plays the load-bearing effect, the multiple-layer horizontal gripper shoe 4 that ricker 2 both sides are provided with control flume 3 vertically and are set up in parallel with control flume 3, the ricker 2 optional i iron of using, with i iron waist groove as control flume 3, weld side by side some layers of horizontal supporting plate 4 with control flume 3, horizontal supporting plate 4 upsides welding gusset is reinforced; Support 1 is the weld holder of steel plate and angle steel, and support 1 is corresponding with ricker 2, and is fixedly connected with support portion as whole safety device with construction wall by bolt, and ricker 2 is positioned at mid-stent; Safety device is two covers, is symmetrical in ricker 2 and is arranged on the support 1.
Safety device comprises safety pole and safe extension spring 5, mode and the support 1 degree of freedom hinged formation lever construction of safety pole rotating at horizontal plane, safe extension spring 5 one ends are connected with support 1 by the hook on the support, and the other end is connected with the safety pole rear end by the hook on the sway bar.
The safety pole upside is connected with the lifting gear of scaffold by connecting strand, and safety pole is with can be hinged in mode and support 1 degree of freedom that perpendicular rotates, jointed shaft 15 ends along the circumferential direction secure fit arrange cam 7 and the formation slip of safety pole rear end, but cam and the rotation of safety pole one, anti-fall extension spring 6 one ends are connected with safety pole by the hook on the safety pole, and the other end is connected with support 1 by the hook on the support.
Under safe extension spring 6 pretightning force effects, safety pole tilts to withstand on a horizontal supporting plate 4 belows to ricker 2, cam 7 rotates with safety pole, its protuberance withstands safety pole, make the safety pole front end embed gathering sill 3, live ricker 2 from the ricker sandwich and prevent the security incidents such as inclination.
Safety pole is comprised of push rod 8 and the top stem casing letter 9 that is coated at push rod 8, push rod and sleeve 9 is with can be hinged in mode and support 1 degree of freedom that perpendicular rotates, push rod 8 outer round surface arrange external screw thread, push rod and sleeve 9 inner circles arrange internal thread, push rod 8 and push rod and sleeve 9 threaded engagement, the length of rotation push rod adjustable safety bar, and also this structure is convenient to dismounting, security performance is high, and is easier for installation.
Threaded engagement arranges stop nut 10 on the push rod 8, and stop nut 10 can prevent that the screw thread between push rod and sleeve 9 and the push rod 8 lost efficacy under pressure, and push rod is pressed in the sleeve, causes safety device to lose efficacy.
Safety pole is comprised of guide pad 11, horizontally disposed connecting rod 12 and lever 13; Connecting rod 12 1 ends are fixedly connected with guide pad 11, the other end and lever 13 front ends are bolted and form L shaped structure, guide pad 11 embeds gathering sill 9, lever 13 middle parts and support 1 are hinged, lever 13 rear ends are connected with safe extension spring 5, and form with the protuberance of cam 7 and to slide, this structure is easy for installation.
Suspension ring 14 are set on the push rod and sleeve 9, and suspension ring are used for connecting steel wire ropes, and safety pole is connected with lifting device for scaffold.
The utility model in use, when scaffold descends, lifting device for scaffold is connected with push rod and sleeve by wire rope, on the wire rope safe flip flop equipment can be set, such as turnbuckle, under the lifting gear effect, safety pole is pulled to vertical state, cam rotates an angle thereupon, make the protuberance of cam no longer withstand the safety pole rear end, safety pole also rotates an angle under the effect of safe extension spring, make the certain space of formation between safety pole front end and the control flume, thereby safety device does not affect the normal decline of ricker; When scaffold is in abnormal operating state, when safe flip flop equipment disconnection or wire cable rupture, lifting gear disappears to the pulling force of safety pole, safety pole promptly tilts to ricker under the effect of safe extension spring, horizontal supporting plate on the ricker is dropped on the safety pole end, the safety pole front end withstands the horizontal supporting plate downside, prevents that it from security incident occuring; Simultaneously, cam is followed safety pole and is rotated an angle, make the protuberance of cam withstand the safety pole rear end, safety pole is rotated to ricker, safety pole front end end embeds control flume, the safety pole of ricker both sides clamps ricker, prevent that it from security incident occuring, when scaffold rises or is static, can lifting device for scaffold be connected with the top stem casing letter, with the rising of scaffold, ricker can oneself be pushed safety pole open, because the interlock effect between safety pole and the safety pole, safety pole can not rise to scaffold yet and impact, as meet accident, the operating principle when descending with scaffold is identical, and the utility model can be from preventing the security incidents such as scaffold tenesmus or inclination with imitating.
