Abstract
The utility model discloses an elevator tensioning device which comprises a heavy block group. The heavy block group is used for vertically tightening a steel wire rope. The heavy block group is connected with one end of a straight beam. A tensioning wheel is fixed in the middle of the straight beam. The tensioning wheel has a connecting effect, so that the steel wire rope is connected with a speed limiter in a winding mode. The other end of the straight beam is fixedly provided with a colliding plate and a connecting plate. The colliding plate is used for collision of a UKS switch and has a safety effect. The UKS switch and a plate piece are fixed on the connecting plate. The plate piece is used for fixing the whole device on a guiding track and has a fixing effect. The elevator tensioning device has the advantages that the device can transmit speed limiter motion and action and enable the function of the speed limiter to be complete, when a car speed reaches a limiting value, electric signals can be emitted, mechanical action can be generated, and elevator safety is guaranteed.

Live in continuation, science and technology is in development, and elevator is also improving.Over 150 years, the material of elevator is by black and white to colored, and pattern, is being made new advances aspect manipulation control to inclined especially by straight step by step---car handle control, push button control, signal control, collection selected control system, man machine communication etc., also there is parallel control in many elevators, intelligent cluster controlled; Double-deck elevator shows saving hoistway space, the advantage of Lifting Convey ability; Pedestrian's time has been saved in the appearance of speed changing type moving sidewalk staircase greatly; The sightseeing elevator of different profiles---fan-shaped, triangle, half rhombus, semicircle, full circle shape makes the sight line that is in passenger wherein no longer seal.
Elevator is in improving the mankind's living standard, and the safety of lift appliance should be also the problem that should not ignore, and therefore, elevator all will arrange system running protection device.Elevator governor is one of safety control parts in elevator safety protection system.When elevator is in operation, no matter which kind of reason exceeds the speed limit car, the danger of even falling, and in the out-of-action situation of every other safety guard, velocity limiter and safety tongs generation linkage action, stops lift car.Velocity limiter safety tongs system is a very important safety device of elevator, it moves the whether normal safe in operation that is not only related to elevator itself, more be related to the safety of people's life and property, therefore, need setting device guarantee velocity limiter in the situation that elevator meets accident, normally to work.
Utility model content
The purpose of this utility model is to provide a kind of elevator expansion apparatus, for transmitting velocity limiter motion and moving and make the function of velocity limiter reach complete, in the time that car speed reaches limit value, can send electric signal and produce mechanical action, ensures the safety of elevator.
For achieving the above object, technical solution adopted in the utility model is:
This device comprises weights stack, and weights stack is connected with one end of straight beam, and the middle part of straight beam is fixed with expansion tightening wheel, and the other end of straight beam is fixed with and hits plate and connecting panel, is fixed with UKS switch and plate on connecting panel.
Preferably, described straight beam is connected with connecting panel by bolt and nut.
Preferably, this device also comprises protective cover.
Preferably, on described plate, have multiple slotted holes.
Preferably, described expansion tightening wheel is fixed by a pin on straight beam.
Preferably, on described expansion tightening wheel, have multiple lightening holes.
Preferably, described protective cover comprises attaching parts and cover body.
Preferably, described weights stack comprises that two upper and lower surfaces all open reeded two little pouring weights composition, and one end of straight beam is fixed between two little pouring weights.
The beneficial effect that this elevator expansion apparatus produces is: this device can transmit velocity limiter motion and moves and make the function of velocity limiter reach complete, in the time that car speed reaches limit value, can send electric signal and produce mechanical action, ensures the safety of elevator.
Brief description of the drawings
Fig. 1 is elevator expansion apparatus structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
