Abstract
The utility model discloses a latch transmission type falling protector which comprises a bottom plate, multiple groups of pulleys, a weight, a rack and an eccentric gear. The multiple groups of the pulleys are distributed on two sides of a guide rail and matched with the guide rail, and the weight is connected with the bottom plate through a buffer device, the rack fixes the weight, the eccentric gear is connected with the bottom plate through an eccentric shaft and matched with the rack, under force of the rack, and the eccentric gear is contacted with the guide rail and presses on the guide rail. The falling protector can timely slow down or stop a hanging basket, safety of persons and goods in the hanging basket is guaranteed.
Description
Technical field
The utility model relates to a kind of latch driving type catching device.
Background technology
Attached lift scaffold, as a kind of advanced auxiliary construction technology high-rise, construction of super highrise building, the application on the building site is more and more universal.Compare with traditional console mode scaffold, overhanging scaffold, it has, and the material of taking is few, and labor intensive is few, does not affect the engineering construction progress, the advantage of outstanding building site image.But, because its Applicative time is shorter, product is still perfect not to the utmost, there is safety defect in various degree in design in the product of using at present, security incident happens occasionally, wherein maximum potential safety hazard is the support body problem of falling, although taked many fall arrest measures, used many fall arrest utensils, but there is perfect not to the utmost place in design aspect, structure is simple and crude, delay of response, phenomenon malfunctioning, that lost efficacy occurs repeatedly, and therefore, the potential safety hazard of attached lift scaffold support body accidental falling does not still obtain eradicating.
The utility model content
Problem for the prior art existence, the purpose of this utility model is to propose a kind of latch driving type catching device, if during the accidents such as load-carrying hanging basket generation hawser fracture, can slow down timely or stop hanging basket, thus the safety of the interior personnel of assurance hanging basket and article.
For reaching this purpose, the utility model by the following technical solutions:
Propose a kind of latch driving type catching device, comprise base plate; Be distributed in the guide rail both sides and cooperate many groups pulley of guide rail; Weight by the buffer connecting bottom board; The fixing tooth bar of weight; By the eccentric shaft connecting bottom board, and the eccentric gear of cooperation tooth bar; Be subjected to the power of tooth bar, eccentric gear contact guide rail and direction guiding rail are exerted pressure.Tooth bar and weight are distributed in the base plate both sides.Comprise four groups of pulleys, and be distributed in twos the guide rail both sides.
Based on disclosing of above technical scheme, the utility model possesses following beneficial effect:
After the utility model is implemented, if during the accidents such as load-carrying hanging basket generation hawser fracture, can slow down timely or stop hanging basket, thereby guarantee the safety of personnel and article in the hanging basket.

The specific embodiment
Further specify the technical solution of the utility model below in conjunction with accompanying drawing and by the specific embodiment:
Embodiment 1
Propose a kind of latch driving type catching device, comprise base plate 1; Be distributed in guide rail 6 both sides and cooperate many groups pulley 2 of guide rail 6; Weight 5 by buffer 4 connecting bottom boards 1; The fixing tooth bar 7 of weight 5; By eccentric shaft connecting bottom board 1, and the eccentric gear 3 of cooperation tooth bar 7; Be subjected to the power of tooth bar 7, eccentric gear 3 contact guide rails 6 and direction guiding rail 6 are exerted pressure.Tooth bar 7 and weight 5 are distributed in base plate 1 both sides.Comprise four groups of pulleys 2, and be distributed in twos guide rail 6 both sides.
In the use procedure, hanging basket is catching device fixedly, and four groups of gears 2 are cooperated installation with guide rail 6, and under normal circumstances, about the hawser pulling hanging basket, at this moment, gear 2 slides along guide rail 6, normal about.When anomaly ratio such as hawser occurring and rupture, hanging basket is in state of weightlessness, accelerate tenesmus, and the interaction relation between weight 6 and the buffer 7 so that weight 6 be subjected to displacement with respect to catching device, because tooth bar 7 is catching device fixedly, so that tooth bar 7 is subjected to displacement, tooth bar 7 moves and drives eccentric gear 3 actions, and eccentric gear 3 rotates, and is subjected to displacement, contact guide rail 6 is also exerted pressure to guide rail 6, under the frictional force effect, slow down or stop catching device, because catching device and hanging basket are fixed, thereby slow down or stop hanging basket, thereby prevent that security incident from appearring in article or personnel in the hanging basket.
The above; it only is the better specific embodiment of the utility model; but protection domain of the present utility model is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and utility model design thereof, all should be encompassed within the protection domain of the present utility model.
