Background technology
When the elevator principle of work is the towing machine traction sheave forward and backward of the driving elevator in being installed in hoistway or in the machine room, the hoist ropes of walking around traction sheave one side drives and car bonded assembly elevator crosshead sheave device, make car in hoistway, move up and down, the hoist ropes of walking around the traction sheave opposite side drives and counterweight bonded assembly counterweight wheel apparatus, makes to move up and down focusing in the hoistway.When car rises in hoistway, descend to focusing in the hoistway; Otherwise then car descends, and counterweight rises.
The elevator crosshead sheave device of prior art, rope sheave is installed in the supporting plate upper end, bolted connection is passed through together with upper junction plate, spring, lower connecting plate successively in the supporting plate lower end, and the crossbeam of car is fixed on the supporting plate lower end, and there is following shortcoming in this elevator crosshead sheave device:
1, since the line of centers along its length of the cross-sectional plane of crosshead sheave supporting plate overlap with the horizontal center line I of described base plate, connect the counterweight wheel and all become 90 degree with the angle that reverses that traction sheave, crosshead sheave are become with the traction sheave steel rope, the cornerite 1 of hoist ropes on traction sheave and crosshead sheave is less, causes the rate of wear of hoist ropes fast, maintenance cost is high.
2, the supporting plate of this crosshead sheave passes through bolted connection together with upper junction plate, spring, lower connecting plate successively, captives joint with the car crossbeam in the lower end of supporting plate, and the arm of force is longer, so structural instability.
3, the rope sheave of this device adopts ironware, and noise is big, Heavy Weight.
4,, and, influenced this stability of structure because the flexible scope of spring is big because this device adopts spring shock absorption, and noise is big.
The utility model content
The technical problems to be solved in the utility model is that a kind of hoist ropes wearing and tearing and low elevator crosshead sheave device of maintenance cost of reducing is provided.
The technical solution of the utility model is, a kind of elevator crosshead sheave device with following structure is provided, it comprises rope sheave, supporting plate and base plate, rope sheave is installed in the upper end of supporting plate, the lower end of described supporting plate is installed on the base plate, described base plate is installed on the car crossbeam, it is characterized in that: the line of centers along its length of described supporting plate cross-sectional plane and the horizontal center line I of described base plate constitute an angle [alpha], and described angle [alpha] is the gained angle [alpha] of described floor level line of centers I left-hand revolution.
After adopting above structure, the utility model compared with prior art has the following advantages:
1, because the line of centers along its length of the cross-sectional plane of crosshead sheave supporting plate and the horizontal center line I of described base plate constitute an angle, causing connecting crosshead sheave and counterweight wheel hoist ropes spacing 24 diminishes, at equal towing machine height, under the track adjusting wheel height, increased the cornerite 1 of hoist ropes on traction sheave, increased traction, reduce the windup-degree of hoist ropes simultaneously, thereby reduce friction, reduced the wearing and tearing of hoist ropes, increase the life-span of hoist ropes, reduced the maintenance cost of elevator.
2, the base plate of this device is connected with car crossbeam lower end by shock absorption device, and the arm of force is shorter, so its structural stability is good.
3, as improving, because the utility model uses the rope sheave of nylon material, so noise is little, and is in light weight.
4, as further improving, the rubber shock-absorbing assembly of this elevator crosshead sheave device can effectively reduce noise, and because the contraction scope is little, so Stability Analysis of Structures.
