Abstract
The invention discloses an anti-falling safety device with a lifting scaffold, which comprises a safety anti-falling device. The safety anti-falling device is provided with a hook plate, a connecting strip and a plate hanging plate, and also comprises an electric hoist and a fixed pulley; the safety anti-falling device is hung upside down and fixed on a hanging rod; the top of the electric hoist and the hook plate on the safety anti-falling device are respectively connected with two ends of a rope of the fixed pulley; and the electric hoist is fixed to a base through a pull rod. The anti-falling safety device has the advantages that not only is the effectiveness of the anti-falling safety device in the severe work environment in a job site improved, but also the triggering speed is improved, the safety of architectural construction is guaranteed, the quantity of major accidents caused by potential safety hazards is effectively reduced, the safety anti-falling device is automatically triggered, and the anti-falling safety device is simple, safe and effectively, is operated simultaneously with the original vibration triggering, and meets the operation requirement of adhering the lifting scaffold.
Description
Technical field
The present invention 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 is at the development and Application initial stage, because the imperfection of safety guard has often caused great, extraordinarily serious safety accident because of some technological deficiency.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 the existing falling proof device is to adopt vibrations to trigger, at the instantaneous trigger safety anti-falling device of accident generation.
Summary of the invention
Goal of the invention: for the problems referred to above, the purpose of this invention is to provide the falling-proof safety device of a kind of sensitivity, reliable attached lift scaffold, ensure 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 the 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 the suspension rod, hook plate on described electric block top and the described safety anti-falling device is connected to the rope ends on the 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 the described electric block.
The principle of the invention 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, advantage of the present invention is not only to have improved the at the construction field (site) validity under the abominable working environment of falling-proof safety device, and improved the rapidity that triggers, guaranteed the safety of building operations, effectively reduce the major accident of bringing owing 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 structural representation of the present invention;
Fig. 2 is scheme of installation of the present invention.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the present invention, should understand these embodiment only is used for explanation the present invention and is not used in and limits the scope of the invention, after having read the present invention, 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 invention.
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 the 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 at 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 installed on the 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 then to be easy to lose efficacy, and can not guarantee the safety device normal operation.
