As a preference, described compensation rope guide wheel is equiform two pulleys, and described pulley is in main box arranged on left and right sides, and the compensation rope of described compensation rope guide wheel arranged on left and right sides is perpendicular to horizontal surface.
For fear of tensioning module out of position, described tensioning module upper end is provided with limit switch, and upper and lower spacing baffle plate is installed on described compensation guide rail, and described upper and lower spacing baffle plate lays respectively at the upper and lower of limit switch.
In order to reduce the wearing and tearing of limit switch, the top of described upper and lower spacing baffle plate is provided with loxosis.
In order to limit tensioning module at predetermined altitude, the upper end of described tensioning module is provided with limiting module, this limiting module comprises limit bracket and the restriction expansion link being connected with compensation guide rail, the upper and lower side of this restriction expansion link is connected with tensioning module respectively at limit bracket, on described restriction expansion link, is set with spring.
The beneficial effects of the utility model are: this device is suspended on car and to pouring weight bottom, use device own wt makes compensation rope keep tensioning state, like this when the shake of compensation rope causes tightening device vibration, under the effect of this device, can obviously reduce Oscillation Amplitude and the frequency of tightening device, reduce vibration and the noise of the generation of car when high-speed cruising, thereby improve the comfort that car is taken, in addition device can also increase the tensile force to compensation rope, improve tension effects, guarantee that compensation rope is stressed evenly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model;
Fig. 3 is the birds-eye view in Fig. 1 ZhongA-A cross section;
Fig. 4 is scheme of installation of the present utility model.
The specific embodiment
With reference to Fig. 1～Fig. 4, a kind of compensating rope of elevator tightening device, comprise hoistway 1, be positioned at the car 2 of hoistway 1, to pouring weight 3, for guiding the car guide rail 21 of car 2 and for guiding the counter weight guide track 31 to pouring weight 3, wherein said the car 2 and lower end of pouring weight 3 is connected with to compensation rope 4, on described compensation rope 4, be provided with tensioning module 5, in described hoistway 1, be provided with compensation guide rail 51, wherein said tensioning module 5 comprises main box 52, be arranged on compensation rope guide wheel 53 in main box 52 and lead boots 54 for what block compensation guide rail 51, wherein said compensation guide rail 51 is positioned at tensioning module 5 both sides, front and back.Wherein compensation rope guide wheel 53 is equiform two pulleys 6, described pulley 6 is distributed in main box 52 arranged on left and right sides, the compensation rope 4 of described compensation rope guide wheel 53 arranged on left and right sides is perpendicular to horizontal surface, adopt Double-wheel structure, and compensation rope 4 two ends are hung vertically in respectively car 2 and to pouring weight 3 bottoms, play tractive effect best.
Described tensioning module 5 upper ends are provided with limit switch 7, and upper and lower spacing baffle plate 71,72 is installed on described compensation guide rail 51, and described upper and lower spacing baffle plate 71,72 lays respectively at the upper and lower of limit switch 7.Described upper and lower spacing baffle plate 71,72 top is provided with loxosis 73, and wherein loxosis 73, with respect to vertical baffle plate, can protect limit switch 7 to reduce wear.When tensioning module 5 is when on compensation guide rail 51, mobile distance surpasses warning value, the upper limit baffle plate 71 or the lower limit baffle plate 72 that are arranged on compensation guide rail 51 can trigger the limit switch 7 in tensioning modules 5, control elevator out of service by control housing.
