The steel wire rope tensioning device of the speed limiter of the elevator is characterized in that a supporting plate is included, a tensioning wheel is arranged on the supporting plate and a counter weight is connected at the lower end of the supporting plate. Side plates are respectively arranged at two ends of one end face of the supporting plate in a vertical direction, corresponding long holes are formed in the side plates in length directions, a supporting arm is arranged in the long holes in a penetrating mode, and idler wheels corresponding to the side plates of two sides are arranged on the supporting arm between the two side plates. One end of the supporting arm is connected with a guide rail, and a control switch in circuit connection with an external controller is arranged at the other end of the supporting arm. The steel wire rope tensioning device of the speed limiter of the elevator is compact in structure, stable in work, smooth in moving, and suitable for the speed limiters of the elevators.
Description
Technical field
The utility model relates to a kind of steel wire rope stretching device, more particularly, relates in particular to a kind of elevator speed limiter wire rope tightening device.
Background technology
In service at elevator,, reasons such as traction not enough, brake failure or braking force not enough and overload drag, hoist ropes fracture malfunctioning owing to control, the capital is caused the lift car hypervelocity and is fallen, will rely on this moment elevator governor to cooperate the stop mechanism on the lift car to brake, car is clamped on the guide rail.Therefore, the velocity limiter on the elevator is the important composition of elevator.In existing elevator governor, the steel wire rope stretching device of its velocity limiter, because structure is undesirable, can occur in actual use owing to the excessive problem that causes whole tightening device to block of the steel rope amplitude of oscillation, simultaneously, because structure is unreasonable, the stroke of traditional tightening device is shorter, and the position is stable inadequately during action, influences the normal operation of elevator governor.
The utility model content
The purpose of this utility model is to provide a kind of compact conformation, working stability at above-mentioned the deficiencies in the prior art, mobile elevator speed limiter wire rope tightening device smoothly.
The technical solution of the utility model is achieved in that a kind of elevator speed limiter wire rope tightening device, comprises support plate, and wherein said support plate is provided with tension wheel, is connected with weight in the support plate lower end; Wherein be respectively equipped with side plate in end face two ends vertically at support plate, be provided with corresponding slotted hole along its length on side plate, be equipped with hold-down arm in slotted hole, the hold-down arm between two side plates is provided with the roller corresponding with the side plate on both sides; A wherein end of described hold-down arm is connected with guide rail, and the other end is provided with the master cock that is connected with the peripheral control unit circuit.
In the above-mentioned elevator speed limiter wire rope tightening device, the support plate of described tension wheel periphery is provided with rope guard.
In the above-mentioned elevator speed limiter wire rope tightening device, described hold-down arm is made up of cantilever and adapter plate; A described adapter plate wherein end is connected with guide rail, and the other end connects cantilever; Described cantilever is located in two slotted holes, and described master cock is arranged on the free end of cantilever, and described roller is arranged on two cantilevers between the side plate.
In the above-mentioned elevator speed limiter wire rope tightening device, the integral structure that described support plate and side plate are formed in one.
The utility model cooperates with side plate by the roller on the cantilever after adopting said structure, and when guaranteeing tension wheel work, support plate can not influence the normal operation of tightening device owing to problem and the cantilever of the amplitude of oscillation are stuck, and it is smooth and easy that assurance is moved, and working stability is higher; Further, by rope guard is set, can prevent the steel rope sideslip effectively.
