Abstract

The invention relates to a sealing device, for a lifting hook type shot blasting machine, on a lifting hook walking channel, in particular to an air bag type track sealing device. The technical scheme adopted by the air bag type track sealing device provided by the invention is that an inner side pedestal is arranged and fixed on the inner side of a lifting rod; an outer side pedestal is arranged and fixed on the outer side of the lifting rod; an inner side pin shaft is rotationally mounted at the right end part of the inner side pedestal; an outer side pin shaft is rotationally mounted at the left end part of the outer side pedestal; an inner side sand-blocking bottom plate is fixed at the top end part of the inner side pin shaft; an outer side sand-blocking bottom plate is fixed at the top end part of the outer side pin shaft; an inner side air bag is fixed on the inner side sand-blocking bottom plate; an outer side air bag is fixed on the outer side sand-blocking bottom plate. The air bag type track sealing device has the advantages of good sealing effect, simple structure, high reliability in operation and the like.

Description

Gasbag-type track seal device

Technical field

The present invention relates to the sealing device on a kind of walking of the suspension hook for hook-type shot-blast cleaner passage, especially a kind of gasbag-type track seal device.

Background technology

At present, hook-type shot-blast cleaner is in when work, has dust fly out from its suspension hook walking passage, not only pollutes plant environment, nor is beneficial to the healthy of operating personnel.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, a kind of good sealing effect, simple in structure, reliable gasbag-type track seal device are provided.

According to technical scheme provided by the invention, described gasbag-type track seal device, in the inner side of suspension rod, be provided with and be fixed with interior wing base, in the outside of suspension rod, be provided with and be fixed with outer wing base, in the right part of interior wing base, be rotatablely equipped with inner side bearing pin, rotate the left part of wing base outside outside bearing pin, top ends at inner side bearing pin is fixed with inner side sand block base plate, top ends at outside bearing pin is fixed with outside sand block base plate, on inner side sand block base plate, be fixed with inner side air bag, on side block sand base plate, be fixed with outside outside air bag.

Upper surface at interior wing base is fixed with inner side elasticity sealing plate, on the elasticity sealing plate of inner side, is fixed with inner seal hairbrush.

The upper surface of wing base is fixed with outer elastic sealing plate outside, is fixed with sealing hairbrush in outside on the elastic packing plate of outside.

At the lateral wall middle part of inner side air bag, be provided with that opening arranges outwardly and be semicircular inner side bayonet socket.

At the madial wall middle part of outside air bag, be provided with that opening arranges inwardly and be semicircular outside bayonet socket.

The present invention has good sealing effect, the advantage such as simple in structure and reliable.

Accompanying drawing explanation

Fig. 1 is structural representation of the present invention.

Fig. 2 is A-A cutaway view of Fig. 1.

The specific embodiment

Below in conjunction with specific embodiment, the invention will be further described.

This gasbag-type track seal device, in the inner side of suspension rod 17, be provided with and be fixed with interior wing base 1, in the outside of suspension rod 17, be provided with and be fixed with outer wing base 2, in the right part of interior wing base 1, be rotatablely equipped with inner side bearing pin 3, rotate the left part of wing base 2 outside outside bearing pin 4, top ends at inner side bearing pin 3 is fixed with inner side sand block base plate 5, top ends at outside bearing pin 4 is fixed with outside sand block base plate 6, on inner side sand block base plate 5, be fixed with inner side air bag 7, on side block sand base plate 6, be fixed with outside outside air bag 8.

Upper surface at interior wing base 1 is fixed with inner side elasticity sealing plate 9, on inner side elasticity sealing plate 9, is fixed with inner seal hairbrush 11.

The upper surface of wing base 2 is fixed with outer elastic sealing plate 10 outside, is fixed with sealing hairbrush 12 in outside on outside elastic packing plate 10.

During work, inner side cylinder 15 promotes inner side sand block base plate 5 around 3 rotations of inner side bearing pin, outside cylinder 16 is pushing away outside sand block base plate 6 around 4 rotations of outside bearing pin, inner side air bag 7 and outside air bag 8 press to suspension rod 17 from inner side and outside respectively, inner side air bag 7 and outside air bag 8 closely compress suspension rod 17 owing to having after elasticity produces deformation, suspension hook walking passage is completely sealed, avoids dust to fly out.

And at the lateral wall middle part of inner side air bag 7, be provided with that opening arranges outwardly and be semicircular inner side bayonet socket 13, at the madial wall middle part of outside air bag 8, be provided with that opening arranges inwardly and be semicircular outside bayonet socket 14, can improve the sealing effectiveness that inner side air bag 7 and outside air bag 8 press to the suspension hook walking passage after suspension rod 17, avoid better dust to fly out.

When mounted, inner side air bag 7 and outside air bag 8 are fixed on corresponding sand block base plate by the lower platen of top board and channel steel shape.
