The falling-preventing device is characterized in that a vertical pulling rod is arranged on the lifting beam through a seat body, a top cover is arranged at the upper end of the vertical pulling rod, a first spring is arranged in the middle of the vertical pulling rod, a hanging part connected with the lifting power machine in a matched mode is arranged at the lower end of the vertical pulling rod, the top cover is connected with a swinging top rod through a second spring, the swinging top rod is connected with horizontal short rods in a matched mode, and the horizontal short rods are arranged on the guide rails at intervals. The falling-preventing device can synchronously, efficiently and reliably supports and prevents the falling climbing frame and the falling guide rails from continuing falling in time instantly a falling accident occurs, not only has the capacity for efficiently preventing the climbing frame from falling, but also has a temporary supporting function when the climbing frame is heightened along with the building, guarantees construction safety, and is easy to process and assemble.
Description
Technical field
The present invention relates to a kind of falling proof device, particularly a kind of falling proof device with duplicate protection, belongs to high-altitude working safety ensuring equipment design and manufacturing technology field.
Background technology
In the time building highrise building or carry out other work high above the ground, mostly assist and fulfil assignment by the mode scaffolding erecting, especially in order to operate with easy to use, existing high-building construction and work high above the ground, all adopt and can realize the frame climbing structure that scaffold rises or declines, to adapt to the operation needs of differing heights.But also brought thus that scaffold surprisingly collapses, falls safety problem.Also there is in addition loading, unloading complicated operation, the time-consuming problem such as take a lot of work.Cause serious accident for avoiding scaffold to meet accident, people have taked a lot of safeguard procedures, as falling proof device etc., but existing falling proof device is owing to there being more fault of construction, the in the situation that of particularly falling in moment, can not in time, effectively play fall arrest, cause protection effect generally undesirable.Therefore be necessary prior art to be improved.
Summary of the invention
For solving existing falling proof device there is moment while falling, because of can not be in time, effective fall arrest causes the problems such as security incident, the invention provides a kind of falling proof device.
The present invention completes by following technical proposal: a kind of falling proof device, comprise the climbing frame with guide rail, and one end is fixed on building, the lifting beam that the other end connects by pulley and guide rail, with with lifting beam, the lifting drive machine of climbing frame associated, it is characterized in that being provided with upper end band top cover by pedestal in lifting beam, the vertical pull bar of middle part with the first spring, this vertical pull bar lower end is provided with the suspension member connecting with lifting drive machine, top cover is connected with swing push rod by the second spring, swinging push rod and interval, to be located at horizontal quarter butt on guide rail matched, cause climbing frame tenesmus so that lifting drive machine breaks down time, make to move on pull bar by the first spring, after quarter butt after push rod being swung by the second spring again and on climbing frame and the guide rail of tenesmus connects, climbing frame and the guide rail that can withstand tenesmus no longer continue tenesmus, ensure safety.
Described pedestal comprises the base with through hole, is located in its on base and establishes uncovered housing with cavity, its top, and vertically the upper end of pull bar protrudes upward through through hole, housing cavity, the uncovered of case top on through hole and base corresponding in lifting beam.
Described top cover is movably placed on case top uncovered, cap base is connected with the first spring, and this first spring housing is contained on vertical pull bar, and is placed in housing cavity, top cover top is provided with the nut being spirally connected with vertical pull bar, so that fixed roof is in vertical pull bar upper end.
The top of described swing push rod be provided with guide rail on the matched groove of quarter butt, bottom is hinged on holder by hinge, this holder is fixed in lifting beam, is provided with the 3rd spring swinging between push rod bottom and lifting beam.
Described suspension member is suspension ring or suspension hook, and its upper end is fixed on the lower end of vertical pull bar, and lower end and lifting drive machine connect, and lifting drive machine is that cucurbit hangs or hoist engine.
The present invention has following advantages and effect: adopt such scheme, can be easily by the vertical pull bar in lifting beam, the first spring, the second spring, swing push rod, in lifting process, meet accident the moment of falling, the climbing frame and the guide rail that synchronously, withstand in time, effectively, reliably tenesmus no longer continue tenesmus, not only there is the ability that prevents that efficiently climbing frame from falling, and can also, in the time that climbing frame is increased with building, play a supportive role, ensure construction safety. temporarilyIn addition, this anti-drop device is all made up of reliable frame for movement and spring structure, has guaranteed the reliability of device, is easy to processing, assembling simultaneously.Be a desirable anti-drop device in fact.
Accompanying drawing explanation
Fig. 1 is the present invention's structural representation;
Fig. 2 is the A-A view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is described further.
Falling proof device provided by the invention, comprise the climbing frame 14 with guide rail 16, and one end is fixed on building 4, the fixed mount 25 of the other end by both sides and on the lifting beam 22 that connects with two parallel guide rails 16 of pulley 24, with with lifting beam 22, the lifting drive machine 19 of climbing frame 14 associated, wherein in lifting beam 22, be provided with upper end band top cover 8 by pedestal, the vertical pull bar 3 of middle part with the first spring 7, these vertical pull bar 3 lower ends are provided with the suspension member 2 connecting with lifting drive machine 19, top cover 8 is connected with swing push rod 11 by the second spring 10, swinging push rod 11 and interval, to be located at horizontal quarter butt 15 between two parallel guide rails 16 matched, described pedestal comprises the base 5 with through hole, be located in its on base 5 and establish uncovered housing 6 with cavity, its top, vertically the upper end of pull bar 3 is through uncovered the protruding upward at the through hole on through hole and base 5 corresponding in lifting beam 22, housing 6 cavitys, housing 6 tops, described top cover 8 is movably placed on housing 6 tops uncovered, top cover 8 bottoms are connected with the first spring 7, and this first spring 7 is sleeved on vertical pull bar 3, and are placed in housing 6 cavitys, top cover 8 tops are provided with the nut 9 being spirally connected with vertical pull bar 3, so that fixed roof 8 is in vertical pull bar 3 upper ends, the top of described swing push rod 11 be provided with guide rail 16 on the matched groove 12 of quarter butt 15, bottom is hinged on holder 23 by hinge 17, this holder 23 is fixed in lifting beam 22, between swing push rod 11 bottoms and lifting beam 22, is provided with the 3rd spring 13, described suspension member 2 is suspension ring 1, suspension ring 1 upper end is fixed on 3 lower ends of vertical pull bar, the hook 18 of lower end and lifting drive machine 19 connects, lifting drive machine 19 hangs for cucurbit, haulage chain 20 one end that cucurbit hangs are fixed on climbing frame 14, the other end is walked around cucurbit and is hung, so that under cucurbit suspender belt is moving, makes the guide rail 16 on climbing frame 14 rise or decline under pulley 24 slides by haulage chain 20.
