Description
Technical field
The utility model is related to a kind of suspension type crosshead sheave device, belongs to elevator technology field.
Background technology
With reference to Fig. 1, existing suspension type crosshead sheave device, it includes supported on both sides plate 11, positioned at the top of supporting plate 11
Transition wheel 12, and bottom support meanss, support meanss include natural rubber 14 and trough plate 15, the two ends of trough plate 15 with branch
Fagging 11 is fixedly connected, and by the open screw hole fitted bolt of natural rubber 14 by trough plate 15 and natural rubber 14 and upper beam 13
It is fixedly connected, so that crosshead sheave device is fixed on upper beam 13.But, the hardness reference value of natural rubber 14 is HS45, and
Using M12 bolt connections upper beam 13 and trough plate 15, when being run above and below elevator, the influence that is under pressure of natural rubber 14 can be present
To the shearing force and tensile force of bolt, so as to cause unsafe factor to exist, elevator safety operation is influenceed.
Utility model content
In order to solve the above technical problems, the utility model provides a kind of suspension type crosshead sheave device, to realize crosshead sheave
The stability of device.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：
A kind of suspension type crosshead sheave device, it is arranged on the upper beam of elevator hoistways, including supported on both sides plate, installed in institute
State the transition wheel on supporting plate top, and the supporting mechanism installed in the supporting plate bottom；
The supporting mechanism includes：Both sides are provided with galvanized steel above and below trough plate and butyl rubber, the butyl rubber
Plate；
Bottom inside of the two ends of the trough plate respectively with supporting plate described in both sides is fixedly connected, the butyl rubber and
Galvanized steel plain sheet is placed at the top of the trough plate, and the trough plate and both sides are provided with to by bolt the fourth of the galvanized steel plain sheet
Base rubber is connected with upper beam locking, so that the crosshead sheave device is arranged on the upper beam.
Wherein, the hardness of the butyl rubber is NR58-HS65.
It is preferred that, the thickness of the galvanized steel plain sheet is 4mm.
Wherein, the trough plate, butyl rubber and galvanized steel plain sheet symmetrically offer two screw holes to use symmetrical junction
Two bolts of structure form firm locking.
By above-mentioned technical proposal, the utility model is by natural rubber is improved to butyl rubber in original design and both sides increase
Galvanized steel plain sheet so that the influence of bolt tension stretch in the structure after improvement, and alleviation power is played by intermediate layer butyl rubber
Effect, because butyl rubber maximum is characterized in molecular structure predominantly cis-structure, therefore elasticity, crack resistance and dynamic property
It is excellent, it is ensured that the shockproof function of rubber blanket, it also ensure that the life-span of rubber blanket.
Brief description of the drawings
