Abstract
The invention discloses an elevator speed limiting device and belongs to the field of elevator safety protection devices. The elevator speed limiting device comprises a car arranged in a shaftway; a steel wire rope is arranged in the shaftway, extends upwards to the position of a machine room floor slab and is connected with a fixing part on the machine room floor slab; the steel wire rope extends downwards to the portion above a pit and is connected with a speed limiter on the car, and a hanging device is arranged at the tail end of the steel wire rope; and an electric switch is arranged on the speed limiter. According to the elevator speed limiting device, the fixing part on the machine room floor slab is connected and fixed to the steel wire rope, the speed limiter and a rope head device are arranged on the car, the hanging device is arranged at the tail end of the steel wire rope, the structure is simple, installation is convenient, and the electric switch is away from the pit and thus is not likely to be corroded, and the fault rate is reduced.
Description
Technical field
The present invention relates to safety protection apparatus for elevator field, be specifically related to a kind of elevator speed governor.
Background technology
Elevator speed governor-its effect is when elevator is out of control or during hypervelocity, limiter of speed electric switch sends electric signal, cutting-off controlling loop, make motor dead electricity and brake, when speed still rises, limiter of speed mechanically handling safety pincers action, car is stuck on guide rail.
Existing elevator speed governor structure chart as depicted in figs. 1 and 2, including machine room limiter of speed (1), steel wire rope (2), car (3), shift mechanism (4), swelling device (5), then hang the steel cable (2) shift mechanism (4) to swelling device (5) midway connection car frame plank at the upper machine room limiter of speed (1) of placing of machine room floor (6).To in its installation process, go machine room that machine room limiter of speed is installed again and go car frame plank that shift mechanism is installed again, go pit (8) that limiter of speed (a swelling device part) is installed again, link together with steel wire rope the most again.Also exist and the problem that trouble, structure complexity and fault rate are higher is installed.
Summary of the invention
For there being the defect of technology on overcoming, it is provided that a kind of elevator speed governor, particularly the structure of elevator speed governor is improved, thus facilitate in-site installation and reduce fault rate.
For achieving the above object, the present invention uses such as purgation technical scheme:
A kind of elevator speed governor, including the car being arranged in hoistway, is provided with steel wire rope in hoistway, described steel wire rope extends upwardly at machine room floor, and is connected with the fixed part on machine room floor；Described steel wire rope extends downward above pit, and is connected with the limiter of speed on car, and the end being positioned at steel wire rope is provided with suspension arrangement；It is provided with electric switch on described limiter of speed.
Further, described car upper end is provided with the fag end device being connected with steel wire rope, and described fag end device includes roller and the support being fixed on car, and described roller is connected with steel wire rope.
Further, described number of rollers is two, and described steel wire rope connects with serpentine canoe and two rollers.
Further, two described rollers are disposed vertically up and down.
Further, two described roller water placing flat.
Owing to technique scheme is used, the present invention compared with prior art has the advantage that
1. electric switch is only installed on limiter of speed, and switch reduces environment in fault rate, and car less and to be dried much relative to melt pit, so electric switch is not easy corrosion fault rate；2. this device steel wire rope be one fix one unsettled, rope stretch nor affects on the action of safety switch, so the most there is not limiter of speed to claim to take turns that switch contact is bad and action；3. steel wire rope half fewer than ordinary construction, on-off ratio ordinary construction one at least less, cost is the lowest.

Detailed description of the invention
Below in conjunction with the accompanying drawings and embodiment the invention will be further described:
Embodiment:
Shown in Fig. 3 Fig. 4 and Fig. 5: a kind of elevator speed governor, including the car 4 being arranged in hoistway 8, steel wire rope 3 it is provided with in hoistway 8, described steel wire rope 3 extends upwardly at machine room floor 7, and be connected with the fixed part 1 on machine room floor 7, described fixed part 1 is equally fixed on top or rail crown, and the effect played is to be fixed steel wire rope one end.Described steel wire rope 3 extends downward above pit 9, and is connected with the limiter of speed 5 on car 3, and the end being positioned at steel wire rope 3 is provided with suspension arrangement 6, so constitutes steel wire rope annexation in hoistway.In order to strengthen the fluency being connected between steel wire rope with car, described car 4 upper end is provided with the fag end device 2 being connected with steel wire rope, and described fag end device 2 includes roller and the support being fixed on car, and described roller is connected with steel wire rope；As it is shown on figure 3, the quantity of roller is two, and vertical distribution between the two, steel wire rope connects with serpentine canoe and two rollers；As shown in Figure 4, the quantity of roller is two, and horizontal distribution between the two, and steel wire rope connects with serpentine canoe and two rollers.It is provided with electric switch on described limiter of speed 5.
Technical solution of the present invention provides a kind of elevator speed governor, compared with prior art has the advantage that
1. electric switch is only installed on limiter of speed, and switch reduces environment in fault rate, and car less and to be dried much relative to melt pit, so electric switch is not easy corrosion fault rate.
2. this device steel wire rope be one fix one unsettled, rope stretch nor affects on the action of safety switch, so the most there is not limiter of speed to claim to take turns that switch contact is bad and action.
3. steel wire rope half fewer than ordinary construction, on-off ratio ordinary construction one at least less, cost is the lowest.
Above-described embodiment only for technology design and the feature of the present invention are described, its object is to allow person skilled in the art will appreciate that present disclosure and to implement according to this, can not limit the scope of the invention with this.All equivalence changes done according to the present invention or modification, all should contain within protection scope of the present invention.
