The utility model is that following technical scheme is achieved:
A kind of Novel lift framing scaffold catching device, comprise catching device body, one-level anti-drop device, spacing anti-tilt device, secondary anti-drop device, described one-level anti-drop device comprises suspension ring, pull rope, Compress Spring, anti-fall tongue, described suspension ring are connected with anti-fall tongue by pull rope, on described anti-fall tongue, Compress Spring are installed; Described spacing anti-tilt device is comprised of two pairs of position-limited wheels, support bar, mounting blocks, and described mounting blocks is fixed by bolts on described catching device body, and support bar is equipped with in described mounting blocks one end, and described support bar is provided with position-limited wheel; Described secondary anti-drop device comprises holder, back-moving spring, sliding bar, sliding seat, trapezoidal anti-fall head, described holder and sliding seat are all fixedly mounted on catching device body, in described holder and sliding seat, be provided with sliding bar sliding back and forth, on described sliding bar, cover has a back-moving spring, one end of described sliding bar is provided with trapezoidal anti-fall head, described trapezoidal anti-fall upper surface is an inclined-plane, and soffit is horizontal plane.
The utility model is provided with two-stage anti-drop device, and when support body drops, the trapezoidal anti-fall head of the anti-fall tongue of one-level anti-drop device and secondary anti-drop device can snap in the guide rail cross bar of lifting false work in time, prevents that support body from falling downwards, realizes multiple drop-proof control.Adopt two-stage anti-drop device, security reliability is higher, and insurance system is larger, even if there is one-level anti-drop device to break down, also can effectively guarantee the safety of workman and equipment, can have sufficient time maintenance and fix a breakdown.
Spacing anti-tilt device of the present utility model is comprised of two pairs of position-limited wheels, support bar, mounting blocks, position-limited wheel is installed in the guide rail of lifting false work, both can guarantee the steadily operation up and down of whole device, plays guide effect, can prevent again toppling over of whole device, play balanced action.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, 1-catching device body, 2-holder, 3-sliding bar, 4-pull rope, 5-suspension ring, 6-mounting blocks, 7-support bar, 8-position-limited wheel, 9-Compress Spring, 10-anti-fall tongue, 11-guide rail, 12-cross bar, 13-trapezoidal anti-fall head, 14-sliding seat, 15-back-moving spring.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
A kind of Novel lift framing scaffold catching device, is arranged on the guide rail 11 of lifting false work, is provided with evenly spaced cross bar 12 in the guide rail 11 of lifting false work.As shown in Figure 1, Novel lift framing scaffold catching device is being comprised of catching device body 1, one-level anti-drop device, spacing anti-tilt device, secondary anti-drop device, described catching device body 1 top is provided with one-level anti-drop device, described one-level anti-drop device below is provided with secondary anti-drop device, and spacing anti-tilt device is equipped with in catching device body 1 side.
One-level anti-drop device comprises suspension ring 5, pull rope 4, Compress Spring 9, anti-fall tongue 10, and described suspension ring 5 are connected with anti-fall tongue 10 by pull rope 4, on described anti-fall tongue 10, Compress Spring 9 are installed.When support body promotes or decline, suspension ring 5 are under pulling force effect, and by pull rope 4, by the anti-fall cross bar 12 in anti-fall tongue 10 pull out guide rail 11, Compress Spring 9 is compressed simultaneously, and support body now can free lifting.If lifting crane gear chain or suspension ring 5 catastrophic failures, the pulling force on catching device pull rope 4 disappears, and Compress Spring 9 is upspring, and anti-fall moment is inserted in the anti-fall cross bar 12 at guide rail 11 intervals, stops timely and effectively support body to fall.
Spacing anti-tilt device is comprised of two pairs of position-limited wheels 8, support bar 7, mounting blocks 6.Mounting blocks 6 is fixed by bolts on described catching device body 1, convenient installation and later maintain and replace.Support bar 7 is equipped with in mounting blocks 6 one end, described support bar 7 is provided with position-limited wheel 8, described position-limited wheel 8 is installed in the guide rail 11 of lifting false work, can move up and down along guide rail 11, can effectively stop support body outward direction to topple, can guarantee again the steadily operation up and down of whole device, play guide effect.The utility model adopts two pairs of position-limited wheels 8, and compared with single position-limited wheel 8, its anti-dumping performance is more reliable, and operation is more steady up and down.
Secondary anti-drop device comprises holder 2, back-moving spring 15, sliding bar 3, sliding seat 14, trapezoidal anti-fall 13, holder 2 and sliding seat 14 are all fixedly mounted on catching device body 1, in holder 2 and sliding seat 14, be provided with sliding bar 3 sliding back and forth, on sliding bar 3, cover has a back-moving spring 15, one end of sliding bar 3 is provided with trapezoidal anti-fall 13, trapezoidal anti-fall 13 upper surfaces are an inclined-plane, and soffit is horizontal plane.Support body is in uphill process, guide rail 11 cross bars 12 in the inclined-plane contact guide rail 11 of trapezoidal anti-fall 13 upper surfaces, under the effect of join on skew touch, trapezoidal anti-fall 13 and connected sliding bar 3 retraction getaway 11 cross bars 12, when support body drops, under the effect of back-moving spring 15, trapezoidal anti-fall 13 snaps in guide rail 11 cross bar 12 positions in time, prevent that support body from falling downwards, realize multiple drop-proof control.
