Abstract
The invention provides a braking device capable of preventing an elevator car from sliding accidentally. The braking device comprises a braking mechanism, wherein the braking mechanism is arranged on an elevator counterweight mechanism, a guide mechanism and/or an elevator car pulley mechanism for applying braking force to the elevator counterweight mechanism, the guide mechanism and/or the elevator car pulley mechanism. When the loading capacity of an elevator traction mechanism is maintained by utilizing the braking device provided by the invention, the elevator car can be effectively prevented from sliding accidentally; moreover, reasonable elevator wellhole spatial layout and relatively low construction cost are also taken into account.
Description
Technical field
The present invention relates to a kind of traction elevator system, particularly a kind of brake equipment preventing the unexpected slippage of lift car.
Background technology
In existing elevator device, towing machine drives load-carrying element to make car movement.For preventing the unexpected slippage of car, towing machine is equiped with brake equipment with in order to impose effective brake to load-carrying element.But, make the factor of lift car generation slippage numerous and complicated various, on towing machine, only install brake equipment is obviously far from being enough, and how effectively to avoid the unexpected slippage of lift car, take into account simplified structure simultaneously and reduce laid down cost, becoming those skilled in the art's problem demanding prompt solution.
Summary of the invention
The object of this invention is to provide a kind of brake equipment preventing the unexpected slippage of lift car, by simple brake structure and position arrangement flexibly, while effectively avoiding the unexpected slippage of lift car, rational ele-vator shaft spaces layout and comparatively cheap laid down cost are also taken into account.
For solving the problem, the brake equipment of the unexpected slippage of lift car that prevents provided by the invention comprises: stop mechanism, it is placed in Elevator weight sensor mechanism, guiding mechanism and/or elevator car pulley mechanism in order to apply braking force to it.
As a preferred embodiment of the present invention, described stop mechanism is not installed in elevator traction machine.
As a preferred embodiment of the present invention, described stop mechanism is block brake, plate disc brake or caliper brake.
As a preferred embodiment of the present invention, described counterweight mechanism comprise by elevator traction element draw to roller.
As a preferred embodiment of the present invention, described guiding mechanism comprises the track adjusting wheel of being drawn by elevator traction element.
As a preferred embodiment of the present invention, described Ya Sheng mechanism comprises the press rope wheel drawn by elevator traction element.
As a preferred embodiment of the present invention, described stop mechanism comprises at least one block brake, plate disc brake or caliper brake.
Technique effect of the present invention is, while the load-carrying ability keeping elevator traction mechanism, effectively can prevent the unexpected slippage of lift car, meanwhile, also take into account rational ele-vator shaft spaces layout and comparatively cheap laid down cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing and better embodiment, the present invention is further detailed explanation.
Fig. 1 is the schematic structure sketch of better embodiment of the present invention.
Fig. 2 is the schematic structure sketch of the assembling caliper brake of better embodiment of the present invention.
Fig. 3 is the schematic structure sketch of the assembling block brake of better embodiment of the present invention.
Fig. 4 is the schematic structure sketch of the assembling plate disc brake of better embodiment of the present invention.
Detailed description of the invention
As shown in Figure 1, better embodiment of the present invention prevent from the brake equipment of the unexpected slippage of lift car from comprising being placed in the drg of Elevator weight sensor wheel 3, track adjusting wheel Isosorbide-5-Nitrae, press rope wheel 2, car wheel 5 in order to apply braking force to it.Wherein, roller 3, track adjusting wheel Isosorbide-5-Nitrae, car wheel 5 are drawn by elevator traction element.
Brake equipment can be arranged on to roller 3, track adjusting wheel Isosorbide-5-Nitrae, press rope wheel 2 and car wheel one of 5 or some, but brake equipment is not installed on elevator traction machine.
Brake equipment can be one or more in caliper brake, block brake and plate disc brake.
As shown in Figures 2 to 4, caliper brake 6, block brake 7 and plate disc brake 8 all can with 5 taken turns to roller 3, track adjusting wheel Isosorbide-5-Nitrae, press rope wheel 2 and car be connected, the same prior art of connection mode.
Below preferred embodiment of the present invention is illustrated, but the present invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent modification or replacement under the prerequisite without prejudice to the invention spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
