Description
Technical field
This utility model relates to a kind of elevator safety assembly, a kind of elevator speed limit with safety detection function
Device.
Background technology
Elevator governor, is one of safety con-trol part in elevator safety protection system.When no matter elevator is in operation
Which kind of reason makes car exceed the speed limit, the danger even fallen, and the inoperative feelings of every other safety guard
Under condition, then limiter of speed and safety tongs generation linkage action, make lift car stop.
Due to elevator governor only elevator stall when could trigger action, so elevator governor be easy to because of
Permanent triggering and crucial moment malfunctioning (bearing pin at such as ratchet gets rusty), i.e. when elevator speed overruns,
Also cannot discover when elevator governor does not trigger, and then produce potential safety hazard.
Utility model content
The purpose of this utility model is, it is provided that a kind of elevator governor with safety detection function.It can the moment
Gather elevator speed such that it is able to elevator governor is the most reliably carried out safety detection, and then improves the safety of elevator
Performance.
The technical solution of the utility model: there is the elevator governor of safety detection function, it is characterised in that: include rope
Wheel, rope sheave is arranged in mounting seat by rotating shaft, is additionally provided with ratchet in mounting seat；Rope sheave is connected by rotational pin ratchet, spine
Pawl is provided with centrifugal hammer；Mounting seat is provided with the pressing plate of band brake pad, and pressing plate one end is flexibly connected with mounting seat, the pressing plate other end
Connecting has pull bar, pull bar to be also connected with ratchet；Described rotating shaft projects to outside mounting seat, and rotating shaft projects to the part outside mounting seat
Being connected with the power shaft of encoder, encoder is fixed in mounting seat.
In the above-mentioned elevator governor with safety detection function, described ratchet is provided with projection, corresponding in mounting seat
The position of projection offers arc perforate, and one end of arc perforate is provided with travel switch, projection is provided with and re-packs.
In the aforesaid elevator governor with safety detection function, described ratchet connects and has triggering switch, drag link end
Portion connects safety chain switches.
Compared with prior art, this utility model utilizes the encoder in the rotating shaft of rope sheave to carry out adopting of elevator speed
Collection, such that it is able to utilize the velocity information collected that the action of elevator governor is carried out safety detection, it is to avoid elevator is in limit
Speed device continued to run when losing efficacy.This utility model can supplement as the intellectuality of elevator safety repair and maintenance, can be the biggest
The safety guarantee of elevator is improved in degree.
It addition, this utility model also add re-packing on travel switch and ratchet, the action of limiter of speed can be carried out
More accurately detect.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Being labeled as in accompanying drawing: 1-rope sheave, 2-rotating shaft, 3-ratchet, 4-ratchet, 5-centrifugal hammer, 6-pull bar, 7-pressing plate, 8-
Encoder, 9-projection, 10-arc perforate, 11-travel switch, 12-re-packs, and 13-triggers switch, 14-safety chain switches, 15-
Mounting seat, 16-brake pad.
Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings, but is not intended as this utility model
The foundation limited.
Embodiment.Having the elevator governor of safety detection function, as it is shown in figure 1, include rope sheave 1, rope sheave 1 passes through rotating shaft
2 are arranged in mounting seat 15, are additionally provided with ratchet 3 in mounting seat 15；Rope sheave 1 is connected by rotational pin ratchet 4, and ratchet 4 sets
There is centrifugal hammer 5；Mounting seat 15 is provided with the pressing plate 7 of band brake pad 16, and pressing plate 7 one end is flexibly connected with mounting seat 15, and pressing plate 7 is another
One end connects has pull bar 6, pull bar 6 to be also connected with ratchet 3；Described rotating shaft 2 projects to outside mounting seat 15, and rotating shaft 2 projects to peace
Part outside dress seat 15 is connected with the power shaft of encoder 8, and encoder 8 is fixed in mounting seat 15.Described ratchet 3 is provided with convex
Post 9, in mounting seat 15, the position of corresponding projection 9 offers arc perforate 10, and one end of arc perforate 10 is provided with travel switch 11,
It is provided with on projection 9 and re-packs 12.Connecting on described ratchet 4 and have triggering switch 13, pull bar 6 end connects safety chain switches
14。
Operation principle of the present utility model: under normal circumstances, when elevator speed exceedes the speed of setting, centrifugal hammer
By sufficiently large centrifugal force so that ratchet moves inward, catching on ratchet, now rope sheave drives pawl wheel, the ratchet of rotation
Pulling pull bar and shift mechanism (lifting safety tongs), pull bar pulls pressing plate to be close to rope sheave and is braked.Projection is opened at arc simultaneously
Moving in hole, after projection moves certain position, re-pack triggering travel switch, now can accurate response actual act situation.When
Encoder detects that elevator speed exceedes the speed of setting, and travel switch does not trigger signal, then can determine whether limiter of speed
Malfunctioning, answer hard stop to overhaul.
