Abstract
The utility model relates to an anti-falling device, in particular to an anti-falling device used on a scaffold which can be lifted. The anti-falling device comprises an anti-falling wedge, a draw bar, an anti-falling pulling clasp, a guide rail, a spring and a top cap, wherein one end of the draw bar is fixedly connected with the scaffold, and the other end of the draw bar is connected with a nut by the top cap at the top end of a sleeve; the spring is positioned in the sleeve; the anti-falling pulling clasp is pressed by the edge of the top cap; and the anti-falling pulling clasp is connected with the base thereof by a hinge pin; the base is a slope of which the upper part is smaller and the lower part is larger; the base is connected with the guide rail; the lower part of the anti-falling wedge is smaller and the upper part is larger; the top of the anti-falling wedge is connected with a handle; the handle is provided with a boss of which the upper part is thick and the lower part is thin; and the boss is clamped in a clamping slot of the anti-falling pulling clasp. The anti-falling device has a simple structure, is convenient to manufacture and performs a good anti-falling effect.
Description
Technical field
The utility model relates to a kind of anti-drop device, the falling proof device that uses on particularly a kind of scaffold that promotes.
Background technology
When needs carry out work high above the ground, generally all adopt the mode less important work that scaffolds erecting, particularly for easy for operation; Scaffold realized can upper and lower lifting when adapting to operation height, the accidental falling of scaffold has just become bigger potential safety hazard, has at present than several anti and attaches the device that falls; But owing to exist certain defective on the structure; Under the moment weightlessness situation of falling, anti-fall effect is undesirable, often causes security incident.
Summary of the invention
The purpose of the utility model is intended to overcome the defective of prior art, and a kind of falling proof device simple in structure, easy to make, safe in utilization is provided.
The described falling proof device of the utility model is made up of anti-fall wedge, pull bar, the anti-fall button, guide rail, spring, top cover pulled, and an end of pull bar is connected with the scaffold fastening devices; The other end is connected with nut through the top cover on sleeve top, and spring is positioned at sleeve, and the anti-fall button of pulling is pushed down at the edge of top cover; The anti-fall button of pulling is that bearing pin is connected with its base, and base is up-small and down-big slope, and base is connected with guide rail; Little going up greatly under the anti-fall wedge; The top of anti-fall wedge is connected with handle, and upper coarse and lower fine boss is arranged on the handle, and boss is stuck in the anti-fall draw-in groove of pulling button.
There is protruding boss described top cover below, and the size diameter of boss and the size diameter of sleeve lining are complementary.
The described falling proof device of the utility model, an end of pull bar is connected with the scaffold fastening devices, and the elastic force that the weight of this fastening devices and sleeve inner spring are born is suitable, and the other end is connected with nut through the top cover on sleeve top; Spring is positioned on the pull bar of sleeve, and the anti-fall button of pulling is pushed down at the edge of top cover, and there is protruding boss the top cover below, and the size diameter of boss and the size diameter of sleeve lining are complementary; Prevent that top cover is subjected to displacement, the anti-fall button of pulling is that bearing pin is connected with its base, and base is up-small and down-big slope; Base is connected with guide rail, little going up greatly under the anti-fall wedge, and the top of anti-fall wedge is connected with handle; Upper coarse and lower fine boss is arranged on the handle, and boss is stuck in the anti-fall draw-in groove of pulling button, and anti-fall button one end of pulling is pushed down by top cover; The other end is connected with anti-fall wedge, bears the gravity of anti-fall wedge, becomes a lever.When fracture took place the fastening devices of fixing scaffold, spring no longer bore the weight of fastening devices and upsprings, and the back elastic force of upspringing is upspring top cover moment of sleeve; The top cover anti-fall button of pulling of upspringing loses pressure and under the effect of anti-fall wedge gravity, topples over to anti-fall wedge one end; The anti-fall anti-fall wedge handle of pulling in the button draw-in groove skids off draw-in groove, and downward landing under the effect of gravity is because the anti-fall up-small and down-big slope of button base of pulling; And anti-fall wedge is up big and down small slope; The two tightens under the effect of gravity each other, thereby the gap between base and the guide rail is stuck, plays anti-fall effect.The utility model is simple in structure, and is easy to make, and that is played is anti-fall effective.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model working state structure sketch map.
Among the figure, the anti-fall wedge of 1-, 2-pull bar, the anti-fall button of pulling of 3-, 4-guide rail, 5-spring, 6-top cover, 7-sleeve, 8-nut, 9-base, 10-bearing pin.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation, but be not limited to embodiment.
Embodiment 1
The described falling proof device of the utility model is made up of anti-fall wedge 1, pull bar 2, the anti-fall button 3, guide rail 4, spring 5, top cover 6 pulled, and an end of pull bar 1 is connected with the scaffold fastening devices; The other end is connected through the top cover 6 on sleeve 7 tops and with nut 8, and spring 5 is positioned at sleeve 7, and the anti-fall button 3 of pulling is pushed down at the edge of top cover 6; The anti-fall button 3 of pulling is connected for bearing pin 10 with its base 9, and base 9 is up-small and down-big slope, and base 9 is connected with guide rail 4; 1 time little going up greatly of anti-fall wedge; The top of anti-fall wedge 1 is connected with handle, and upper coarse and lower fine boss is arranged on the handle, and boss is stuck in anti-fall pulling in button 3 the draw-in groove.There is protruding boss described top cover 6 belows, and the size diameter of the size diameter of boss and sleeve 7 inwalls is complementary.
