Brief description of the drawings
Fig. 1 is boiler furnace hoistable platform anti-falling safety device structure chart of the present invention.
Fig. 2 is anti-falling safety device scheme of installation on inspection platform.
Embodiment
With reference to Fig. 1, Fig. 2, a kind of boiler furnace hoistable platform anti-falling safety device, including hoisting ring 1, spring 2, spring housing
3rd, catching device 4, connection shaft assembly 5, hitch 6, protection rope 9, brake block 10 and casing 11；
The upper end of suspension ring 1 is connected with hoisting rope 13, and lower end is connected with spring housing 3, and spring 2 is arranged in spring housing 3, bottom
Contacted with the cavity bottom of spring housing 3, top contacts with casing top；
The bottom of spring housing 3 is connected with the one end of catching device 4, and the other end of catching device 4 is connected with brake block 10, among catching device 4
It is arranged on casing, can be rotated around rotary shaft by rotary shaft；Brake block 10 is arranged on 9 both sides of protection rope, for hoistable platform
Protection rope 9 is clamped when falling；
Casing 11 is fixedly connected by coupling shaft assembly 5 with hitch 6, and inspection platform I-beam 8 passes through hitch 6, is led to
Fixing screws 7 are crossed to fasten.
The quantity of the catching device 4 and brake block 10 is two, and one end and the bottom of spring housing 3 of two catching devices 4 turn
Dynamic connection, the other end are connected with a brake block 10 respectively, and two brake block 10 are oppositely arranged, the opposite one side of two brake block 10
The inner side of casing 11 is arranged on by slide rail, two slide rail spacing from top to bottom become larger, and the spacing of two brake block 10 is by upper
Become larger under.Two opposite sides of brake block 10 are provided with tooth-shape structure, for clamping protection rope 9.9 one end of protection rope are consolidated
It is scheduled on boiler top, the free lowering of the other end.
During normal work, hoisting rope is fixed on hoisting ring 1, and lifting force forces spring 2 to compress, and catching device 4 is rotated simultaneously
Brake block 10 is driven to move down, so that the space between two pieces of brake block l0 becomes big, protection rope 9 is worn between two pieces of brake block l0
Enter, in the state of not stressing.
Once hoisting wirerope is broken, the pulling force of lifting hoisting ring 1 releases, effect of the spring 2 in its own elasticity tension
Lower reset, rotate catching device 4 and drive brake block 10 to move up, so that brake block 10 tightly embraces protection rope 9, platform is prevented
Falling safety device is fixed on protection rope 9 and no longer dropped.
Fig. 2 scheme of installations on inspection platform for the present invention, wherein inspection platform I-beam 8 are the master of inspection platform
Beam, for fixing screws 7 using M12 bolt, bolt aperture is Φ 12.5mm, is anchored on the center line of the width of hitch 6；
