Description
Technical field
The present invention relates to a kind of instantaneous safety for villa elevator, belong to elevator car safety technical field.
Background technology
As economic construction of China quickly well develops, real estate is thriving, with the improvement of people's living standards,
Requirement to inhabitation also improves constantly, and the high-end house of multilayer independent organic whole structured emerges in multitude, the market demand of villa elevator
Also it is subsequently formed.
The security of villa elevator is to lift the important indicator of villa elevator performance.Safety tongs is that one kind makes car or counterweight
The mechanical safety member of stop motion, when there is accident and overspeed in elevator, limiter of speed triggering safety tongs running.Early stage
Elevator instantaneous safety pliers, such as the safety tongs disclosed in China Patent No. ZL97219405.3, when actual safety tongs acts,
Twin roller group and voussoir can be moved up, it is necessary to one block of very thick steel plate is additionally arranged at the bottom in lift car, to prevent unilateral voussoir
It is moved through limiting and departing from caliper upwards, otherwise safety tongs absorbs energy and will substantially reduced, and influences the safe operation of elevator.Reality is
Although installing the demand that steel plate disclosure satisfy that actual use additional, which results in being significantly increased for elevator manufacturing cost.In addition, install additional
Steel plate also makes the structure of elevator become complicated, weight increase.
In summary, in technical field of elevator manufacturing, all expect it is a kind of higher brake force can be both provided, can reduce again
The instantaneous safety of villa elevator manufacturing cost.
The content of the invention
It is an object of the invention to overcome deficiency of the prior art, there is provided a kind of instantaneous formula for villa elevator is pacified
Full pincers, solve the technical problem that safety tongs brake force is small in the prior art.
In order to solve the above technical problems, the invention provides a kind of instantaneous safety for villa elevator, its feature
It is, including caliper, braked wheel, keep plate and limiting plate that the passage passed through for cage guide is offered on the caliper, it is described logical
The sectional area in road is the right-angled trapezium that upper bottom edge is less than bottom, and braked wheel is placed at the hypotenuse of passage, and limiting plate is fixed on
There is by the hypotenuse of caliper upper channel and between limiting plate and caliper gap, keep plate is laterally located in gap, one end of keep plate
Braked wheel, the middle-end connection speed limit rope of keep plate are connected, the other end of keep plate is provided with connecting pole, and limiting plate is provided with insertion
Waist hole, connecting pole is through waist hole and can be moved in waist hole.
Further, the axis of waist hole and the hypotenuse of passage are parallel.
Further, the gradient of the axis of waist hole is less than the gradient of the hypotenuse of passage.
Further, the junction of limiting plate and caliper is additionally provided with packing ring, and the thickness of packing ring is more than the thickness of keep plate.
Further, limiting plate is fixed by bolt and caliper, and packing ring is set on bolt.
Further, the outer surface of braked wheel is provided with annular knurl.
Compared with prior art, the beneficial effect that is reached of the present invention is：The instantaneous safety of the present invention has braking
The advantages of power is bigger, simple in construction, and also simplify villa elevator structure, reduce elevator load bearing and villa elevator is manufactured into
This.

Embodiment
The invention will be further described below in conjunction with the accompanying drawings.Following examples are only used for clearly illustrating the present invention
Technical scheme, and can not be limited the scope of the invention with this.
As depicted in figs. 1 and 2, a kind of instantaneous safety for villa elevator provided by the invention, it is characterized in that, bag
Caliper 1, braked wheel 2, keep plate 3 and limiting plate 4 are included, the passage passed through for cage guide is offered on the caliper 1, it is described logical
The sectional area in road is the right-angled trapezium that upper bottom edge is less than bottom, and braked wheel 2 is placed at the hypotenuse of passage, and limiting plate 4 is fixed
There is gap by the hypotenuse of the upper channel of caliper 1 and between limiting plate 4 and caliper 1, keep plate 3 is laterally located in gap, keep plate 3
One end connection braked wheel 2, the middle-end connection speed limit rope 5 of keep plate 3, the other end of keep plate 3 is provided with connecting pole 3-1, spacing
Plate 4 is provided with the waist hole 4-1 of insertion, and connecting pole 3-1 is through waist hole 4-1 and can be moved in waist hole 4-1.
The working condition of safety tongs of the present invention is divided into two kinds of running status and on-position.When safety tongs is in running status
I.e. the normal operating condition of elevator when, limiter of speed is failure to actuate, and speed limit rope 5 does not produce upward pulling force, and keep plate 3 is located at lower section, even
The lower end that post 3-1 is located at waist hole 4-1 is connect, braked wheel 2 is located in passage close to the relatively low position in oblique waist side, leads to right-angled trapezium
Guide rail of enough spaces to elevator is left by and between being left between braked wheel 2 and cage guide close to straight waist side in road
Gap.When the speed of elevator exceedes the maximal rate that limiter of speed allows, limiter of speed sends action, clamps speed limit rope 5 and produces upwards
Pulling force, speed limit rope 5 drive keep plate 3 it is rapidly moving upward so that braked wheel 2 is rapidly moving upward along the hypotenuse of passage, subtracts
It is small with the gap of cage guide until contacted with cage guide and rubbing action occur, by lift car stop on guide rail, with
Protect the security of elevator；And during keep plate moves up, connecting pole 3-1 moves up along waist hole 4-1, can make braked wheel
2 move up during also by the thrust to passage straight flange, increase the pressure between braked wheel 2 and cage guide, and then increase system
Frictional force between driving wheel 2 and cage guide, brake force is improved, while limit connecting pole 3-1 moves up and down scope so that
Keep plate 3 is without departing from safety tongs body during braking.
As the preferred embodiments of the present invention, waist hole 4-1 axis is parallel with the hypotenuse of passage.Further, waist hole 4-1
Axis gradient be less than passage hypotenuse gradient, can make braked wheel 2 move up during also by passage straight flange
Thrust, increase the frictional force between braked wheel 2 and cage guide, further improve braking effect.
Further, the junction of limiting plate 4 and caliper 1 is additionally provided with packing ring, and the thickness of packing ring is more than the thickness of keep plate,
So as to ensure that the keep plate 3 being arranged between limiting plate 4 and caliper 1 can be moved flexibly.Packing ring is stressed member, in this implementation
In example, the material selection stainless steel of packing ring.
Further, limiting plate 4 is fixed by bolt and caliper 1, and packing ring is set on bolt.Bolt cause limiting plate 4,
Packing ring is closely connected with caliper 1, plays positioning action, and keep plate 3 is flexibly connected by connecting pole 3-1 with limiting plate 4,
In the presence of bolt, whole safety tongs is connected as an entirety.
Further, the outer surface of braked wheel 2 is provided with annular knurl, improves the coefficient of friction of braked wheel 2, improves braking effect
Fruit.
Described above is only the preferred embodiment of the present invention, it is noted that for the ordinary skill people of the art
For member, without departing from the technical principles of the invention, some improvement and deformation can also be made, these are improved and deformation
Also it should be regarded as protection scope of the present invention.
