Description
Technical field
The utility model belongs to elevator technology field, specifically a kind of gradual multiple-protection safety for elevator
Pincers.
Background technology
Safety tongs is the important safety component of lift facility, can elevator overspeed and it is out of control when play safety guarantee weight
Act on, it may be said that just because of the appearance and development of safety tongs, just becoming elevator, a kind of skyscraper is essential to hang down
Straight means of transport.The action of safety tongs device is rope-clamping pliers is clamped governor rope by limiter of speed action, as carriage is downward
Operation, governor rope lifting safety tongs link mechanism, the action of safety tongs link mechanism, drives safety tongs braking member to be connect with guide rail
Touch, the safety tongs on guide rail both sides is simultaneously clamped on guide rail, reach carriage stop.Safety tongs be typically mounted at carriage bottom girder or
On two heel posts, when safety tongs is failure to actuate, voussoir keeps the gap of 2~3mm with working face of guide rail.Two side clearance of safety tongs is equal
Even, when action, can make the reliable stop of carriage on guide rail.But since the structure of current safety tongs also has some unreasonable parts, lead
It is caused often easily to break down, failure cause is complicated and changeable, and the factor for inspiring its malfunction is also more, therefore exists certain
Security risk, it is possible to have serious consequences to elevator and passenger.
The content of the invention
The technical problem to be solved by the present invention is to provide a kind of gradual multiple-protection safety tongs, good antiskid effect,
It ensure that the effect of stop.
In order to solve the above-mentioned technical problem, the utility model takes following technical scheme：
A kind of gradual multiple-protection safety tongs, including voussoir on safety gear block and be oriented to voussoir, voussoir and
It is oriented to voussoir and sets two respectively, voussoir is close to cage guide, and two voussoirs and two guiding voussoirs are respectively with elevator
It is symmetrical arranged centered on guide rail, is equipped between voussoir and guiding voussoir and is oriented to ball, the voussoir surface opposite with voussoir is oriented to is protected
Maintain an equal level row, on voussoir attaching have control stick, the medial surface of the voussoir is equipped with gullet plate, and voussoir is internally provided with compression spring, this
Compression spring one end is connected with gullet plate, is connected inside the other end and voussoir, and the surface which contacts with cage guide is set
For zigzag, two are oriented between voussoir equipped with connection elastic component.
The connection elastic component includes elastic connection sleeve and compression spring, and compression spring is threaded through elastic connection sleeve
It is interior, and the both ends of the compression spring and elastic connection sleeve are oriented to voussoir with two respectively and are fixedly mounted.
The leading flank of the safety gear block is additionally provided with baffle, which is equipped with guide groove, and voussoir is inserted by guide finger
In guide groove, the guide groove is parallel with the orientation of ball.
Compression spring inside the voussoir is obliquely installed.
Compression spring horizontal inside the voussoir is set.
One connection elastic component is at least set between described two guiding voussoirs.
The utility model can produce certain screen resilience, while utilize guiding wedge by the compression spring in voussoir
Flexible connector in block, further enhancing resilience force, so that being provided with the pressure that voussoir is acted on cage guide
Certain elasticity, produces relatively soft stop effect.
Brief description of the drawings
Attached drawing 1 is the utility model section structure diagram.
Embodiment
For that can further appreciate that the feature of the utility model, technological means and the specific purposes reached, function, below
The utility model is described in further detail with embodiment with reference to attached drawing.
As shown in Figure 1, the utility model discloses a kind of gradual multiple-protection safety tongs, including installed in safety tongs
Seat（It is not shown）On voussoir 7 and be oriented to voussoir 3, voussoir 7 and be oriented to voussoir 3 set two respectively, voussoir 7 is close to elevator and is led
Rail 1, and two voussoirs 7 and two guiding voussoirs 3 are symmetrical arranged centered on cage guide 1 respectively, and voussoir 7 is with being oriented to voussoir
Be equipped between 3 and be oriented to ball 6, voussoir 7 and be oriented to the opposite surface keeping parallelism of voussoir 3, on voussoir 7 attaching have control stick 2, institute
The medial surface for stating voussoir 7 is equipped with gullet plate 10, and voussoir 7 is internally provided with compression spring 9,9 one end of compression spring and gullet plate 10
Connection, the other end and the inside of voussoir 7 connect, and the surface which contacts with cage guide is set to zigzag, two guiding wedges
Connection elastic component 11 is equipped between block 3.Connecting elastic component 11 includes elastic connection sleeve and compression spring, and compression spring is threaded through
In elastic connection sleeve, and the both ends of the compression spring and elastic connection sleeve are oriented to voussoir with two respectively and are fixedly mounted.
The leading flank of the safety gear block is additionally provided with baffle 5, which is equipped with guide groove 4, and voussoir 7 passes through guide finger 8
It is inserted into guide groove 4, the guide groove is parallel with the orientation of ball.Band dynamic voussoir moves up when control stick carries upwards,
It is close to cage guide, braking action is played to cage guide.Guide finger displacement in guide groove, so that voussoir
Moving up and down more has directionality.
Compression spring inside the voussoir is obliquely installed.Or the compression spring horizontal inside voussoir is set.
One connection elastic component is at least set between described two guiding voussoirs.
In the utility model, control stick is lifted up voussoir, and voussoir is closely adhered to play braking work on cage guide
With.With fitting closely between voussoir and cage guide, voussoir can produce a degree of deformation, so that inside voussoir
