Abstract
The utility model discloses a falling prevention safety device adhering to a lifting scaffold. The falling prevention safety device adhering to the lifting scaffold comprises a safety falling prevention machine, wherein the safety falling prevention machine comprises a hook plate, a connecting piece and a pull hanging rod, and further comprises an electric hoist and a fixed pulley, the safety falling prevention machine is fixed on a suspender in an upside-down hanging mode, the top portion of the electric hoist and the hook plate on the safety falling prevention machine are respectively connected with the two ends of a rope on the fixed pulley, and the electric hoist is fixed with a base through a pull rod. The falling prevention safety device adhering to the lifting scaffold has the advantages of improving effectiveness of the falling prevention safety device under a poor working environment in a construction site and triggered rapidity, ensuring constructional safety, and effectively reducing major accidents caused by potential safety hazard. The falling prevention safety device achieves triggering the safety falling prevention machine automatically, and is simple, safe and effective. The falling prevention safety device can work with an original vibration trigger simultaneously, and therefore the operating requirements of adhering to the lifting scaffold are met.
Description
Technical field
The utility model relates to a kind of safety device, particularly a kind of falling-proof safety device of the attached lift scaffold when work high above the ground.
Background technology
Along with the development of national economy, China's population day more increases severely, and highrise building is also more and more.In construction, attached lift scaffold takies the advantages such as resource is few, cost is low, effect is high, labour intensity is low, use is safe, easy for installation with it, is adopted by increasing enterprise in high building project.But attached lift scaffold due to the imperfection of safety guard, has often caused great, extraordinarily serious safety accident because of some technological deficiency at the development and Application initial stage.For this reason, the former Ministry of Construction has issued " building operations attached scaffold management temporary provisions ", the 19 regulation wherein: " attached lift scaffold should have enough intensity and the suitable support body of rigidity; have the braced structures of adhering to of the safe and reliable engineering structures characteristics that can adapt to, should have safe and reliable Overthrow preventing device, falling proof device." the 25 regulation: " falling proof device must be sensitive, reliable, and braking distance must not be greater than 80mm for the monolithic attached lift scaffold, must not be greater than 150mm for the one chip attached scaffold.”
Safety anti-falling device in existing falling proof device is to adopt vibrations to trigger, at the instantaneous trigger safety anti-falling device of accident generation.
The utility model content
The utility model purpose: for the problems referred to above, the purpose of this utility model is to provide the falling-proof safety device of a kind of sensitivity, reliable attached lift scaffold, ensures the safety of work high above the ground.
Technical scheme: a kind of falling-proof safety device of attached lift scaffold, comprise safety anti-falling device, have hook plate, brace on described safety anti-falling device, pull peg, also comprise electric block, fixed pulley, described safety anti-falling device reversal of the natural order of things is fixed on suspension rod, hook plate on described electric block top and described safety anti-falling device is connected to the rope ends on described fixed pulley, and described electric block is fixed by pull bar and base.
The described rope that connects described hook plate and described electric block top has the activity surplus of 10～20mm.
Described fixed pulley is arranged at the top between described safety anti-falling device and described electric block.
the utility model principle is to adopt fixed pulley and rope as the instantaneous trigger device of safety anti-falling device, change installation site and mounting means and the mechanical triggering mode of safety anti-falling device, after the electric block chain rupture, under bounce and action of gravitation, electric block moves downward the tension rope, by fixed pulley, the hook plate of safety anti-falling device is forced pull-up, make the safety anti-falling device internal construction automatically clamp suspension rod, start safety anti-falling device by the most direct this mode, and shorten braking distance as far as possible, reduce and trigger the path, shorten the triggered time, improve the sensitive reliability of falling-proof safety device.
Beneficial effect: compared with prior art, the utility model has the advantages that and not only improved the falling-proof safety device validity under abominable working environment at the construction field (site), and improved the rapidity that triggers, guaranteed the safety of building operations, effectively reduce the major accident of bringing due to potential safety hazard, falling-proof safety device has been realized automatic triggering safety anti-falling device, installs simple and safe and effective, work simultaneously with original vibrations triggering, satisfied the instructions for use of attached lift scaffold.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is the utility model scheme of installation.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiment only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present utility model.
As shown in accompanying drawing 1,2, a kind of falling-proof safety device of attached lift scaffold comprises safety anti-falling device 1, electric block 5, fixed pulley 6, has hook plate 2, brace 3 on safety anti-falling device 1, pulls peg 4.
Fixed pulley and rope are as the instantaneous trigger device of safety anti-falling device, after the electric block chain rupture, under bounce and action of gravitation, electric block moves downward the tension rope, by fixed pulley, the hook plate of safety anti-falling device is forced pull-up, make the safety anti-falling device internal construction automatically clamp suspension rod.
Under normal lifting operating mode, the suspension rod lower end should not be subjected to the impact of safety anti-falling device, can be free to slide by comparatively safe catching device, but forbids smearing oily substance on suspension rod, in case safety anti-falling device lost efficacy.
In order to realize that falling-proof safety device works under adverse circumstances, Open Side Down that reversal of the natural order of things is arranged on suspension rod for safety anti-falling device, can effectively prevent from losing efficacy because of the damage of components that pollution such as mortar cause, and reduces the security incident of initiation; Adopt fixed pulley and rope as flip flop equipment, fixed pulley requires lower to working environment, and dust and a small amount of mortar can not affect the work quality of fixed pulley, adopts accurate instrument to be easy to lose efficacy, and can not guarantee the safety device normal operation.
