Description
Technical field
The utility model is a kind of anti-off rope device, and is particularly a kind of for tower machine suspension hook anti-off rope device.
Background technology
Anti-off rope device of the prior art is comprised of rope blocking plate, spring and bearing pin, this structure spring failure can occur in use for some time, the rope blocking plate distortion, in use number of times is more owing to the suspension hook lanyard, in case above-mentioned phenomenon occurs, the building site is just removed safety device and is used, and steel cable easily breaks off relations in the lifting process, can cause serious accident.
Chinese patent 01276701.8, a kind of Anti-rope-loosening safety device for crane hook is disclosed, it comprises: anchor ear, magnetic substance, bearing pin, ratchet, gib head, on suspension hook, fix a magnetic substance with anchor ear, ratchet is connected with gib head by bearing pin, magnetic force makes an end of ratchet all the time near magnetic substance, and the other end is then near gib head.This structure relative complex, and poor stability, magnetic substance easily adheres to other foreign material, causes and uses inconvenience.
Summary of the invention
The utility model mainly is to solve the deficiencies in the prior art, compact conformation, and promote the safety of tower machine, the simultaneously easy to operate tower machine suspension hook anti-off rope device that is used for.
Above-mentioned technical matters of the present utility model is mainly solved by following technical proposals:
A kind of for tower machine suspension hook anti-off rope device, comprise splint holder, the bottom centre position of described splint holder is provided with suspension hook, is provided with in the described suspension hook and hangs mouth, and the two ends in the described splint holder are respectively equipped with the locking pulley, described locking pulley room is provided with brings frame together, the top of described splint holder is provided with plintlet, is provided with the adjustment pulley in the described plintlet, is provided with gear rope bar in the described suspension hook, behind the described gear rope bar end with hang the mouth mutually the gear connect, the other end of described gear rope bar is provided with the deadweight bar.
By the deadweight bar deadweight with hang a mouthful automatic locking, easy to operate.
As preferably, described gear rope bar and the integrated distribution of deadweight bar, described gear rope bar fixes by bearing pin and suspension hook with the deadweight bar, and described deadweight bar is angle with gear rope bar and distributes, the length of described deadweight bar is greater than the length of gear rope bar, and described deadweight bar is arc shape.
As preferably, described locking pulley is fixedly connected by sheave shaft and splint holder, the described centre bit of bringing frame together is provided with the multiplying power axle, and the described bottom width of bringing frame together is less than the top width of bringing frame together, and described adjustment pulley is fixedly connected by adjusting sheave shaft and plintlet.
As preferably, described plintlet and splint holder are fixedly connected.
Therefore, the utility model provides is used for tower machine suspension hook anti-off rope device, and compact conformation is easy to maintenance, simple to operate, saves simultaneously cost.
