Utility model content
The utility model purpose be intended to provide it is a kind of it is simple and reasonable, reduce when there is the fortuitous event fallen
The effective length of safety rope, the personnel that prevent from falling are because safety rope length is long and swings the anti-fall dress of the bridge construction damaged
Put.
To realize above-mentioned technical purpose, the technical solution adopted in the utility model is as follows：
A kind of bridge construction anti-drop device, including housing, the housing upper end are fixedly installed installation journal stirrup, the housing
Upper end is provided with first through hole, and the housing lower end is provided with the second through hole, and the enclosure interior is provided with first pulley, self-locking convex
Wheel, the first pulley is connected with connecting rod, and the connecting rod right-hand member is connected with first pulley, the connecting rod left end and housing
Madial wall upper end rotates connection, and the connecting rod right-hand member is also associated with the first flexible member, described first flexible member one end with
Connecting rod right-hand member is connected, and the first flexible member other end connection can be connected with inwall upper end, the self-locking cam by rotating shaft
Housing lower end inside wall is connected to, upwards, the self-locking cam protrusion is connected with the second elasticity member to the self-locking cam lobe
On the left of part, the second flexible member left end connection inner walls, the second flexible member right-hand member connection self-locking cam is protruded
Portion.
Using the utility model of above-mentioned technical proposal, by install journal stirrup can be fixed in bridge construction theme or with
Operation platform is fixedly connected, and safety rope is sequentially passed through to first through hole and the second through hole from top to down, and workmen will can pacify
Full band is connected with the safety rope below the second through hole, safety rope is reserved into one section of disk in housing side, when safety rope does not stress
Wait, positioned at the part of enclosure interior, will be supported by first pulley, its lower end will be far from self-locking cam, safety rope is in moving type
State；When fall situation when, because safety rope upper end is fixed, the personnel that fall are connected by safety belt with safety rope lower end
, safety rope will be straightened under the Action of Gravity Field for the personnel that fall, and the safety rope being straightened will be leaned on to self-locking cam side
Hold together, and safety rope under gravity also will slide downward, the safety rope of slide downward will be sent out the right side of self-locking cam
Raw friction, makes self-locking fin turn right, most safety rope is squeezed in the second through hole to the protuberance of self-locking cam at last, by upper
The effective length of safety rope can be reduced when there is the fortuitous event fallen by stating structure, and the personnel that prevent from falling are because of safety rope length
It is long and swing and damage, and the first flexible member and the second flexible member can make the first cunning after security situation is released
Wheel and second pulley return.
Further limit, the self-locking cam is provided with arc groove along ring circumferential direction, if the arc-shaped groove bottom is provided with
Dry anti-slop serrations.
Arc groove can play spacing left and right to safety rope, prevent safety rope displacement from causing anti-drop function to fail, and recessed
Trench bottom sets some anti-slop serrations, can play the friction between increase safety rope and self-locking cam, make that safety rope slides when
Time can effectively drive self-locking fin to rotate, and improve reliability.
Further limit, second pulley is provided with the right side of second through hole, the second pulley passes through rotating shaft connection and shell
Body madial wall.
Second pulley can reduce the friction between safety rope and the second through hole when safety rope is slided, and prevent safety
Rope abrasion.
Further limit, first flexible member, the second flexible member are spring.
The utility model is compared with prior art, simple and reasonable, when there is the fortuitous event fallen reduce safety rope
Effective length, the personnel that prevent from falling are because safety rope length is long and swings and damages.
