Abstract
The invention discloses progressive type safety tongs of an elevator. The safety tongs comprise a safety tong base, control rods, wedges, guiding wedges, elastic elements, elastic frames, guiding balls and an elevator guide rail. Specifically, the wedges and the guiding wedges are located in the safety tong base, the wedges are attached to the elevator guide rail, the guiding balls are arranged between the guiding wedges and the wedges, and the opposite faces of each guiding wedge and the corresponding wedge are kept parallel; each wedge block is provided with one control rod, the elastic elements are mounted on the elastic frames and make contact with the guiding wedges; a baffle is fixed to the front side face of the safety tong base, guiding grooves are formed in the baffle, and guiding pins are fixed to the positions, corresponding to the guiding grooves, of the wedges and penetrate through the guiding grooves. According to the progressive type safety tongs, the guiding grooves and the guiding pins are additionally arranged, so that the wedges are well guided in the up-down moving process; anti-slide teeth are arranged on the faces, engaged with the elevator guide rail, of the wedges, the anti-slide effect is good, and the brake effect is guaranteed.
Description
Technical field
The present invention relates to a kind of elevator progressive safety gear, belong to elevator safety technical field.
Background technology
Safety tongs is the important safety parts of lift facility, it is possible to elevator overspeed and out of control time play safety guarantee important function, it may be said that just because of appearance and the development of safety tongs, just make elevator become one skyscraper requisite vertical transport instrument.The action of safety tongs device is to make rope-clamping pliers clamp governor rope by limiter of speed action, along with car runs downwards, governor rope lifting safety tongs link mechanism, safety tongs link mechanism action, drive safety tongs braking member and guide rail contact, the safety tongs making guide rail both sides is simultaneously clamped on guide rail, reaches car stop.Safety tongs is typically mounted on car bottom girder or two heel posts, and when safety tongs is failure to actuate, voussoir keeps the gap of 2～3mm with working face of guide rail.Safety tongs two side clearance is wanted uniformly, to make the reliable stop of car during action on guide rail.But owing to the structure of current safety tongs also has some unreasonable parts, causing it to be often susceptible to fault, failure cause is complicated and changeable, and the factor inspiring its misoperation is the most more, therefore there is certain potential safety hazard, it is possible to have serious consequences to elevator and passenger.
Summary of the invention
The technical problem to be solved is the defect overcoming prior art, it is provided that the progressive elevator safety gear that a kind of safety is high, and its design science is reasonable, good braking effect, making the reliable stop of car when ensure that action on guide rail, reduce fault rate, safety is high.
For solving above-mentioned technical problem, the invention provides a kind of elevator progressive safety gear, including safety gear block, stick, voussoir, guide voussoir, flexible member, elastic shelf, guide ball, cage guide；Described voussoir and guide voussoir and be positioned at safety gear block, described voussoir is up-narrow and down-wide trapezoidal, and described voussoir is close to cage guide；Set guiding ball between described guiding voussoir and voussoir, and guide the face keeping parallelism that voussoir is relative with voussoir；Stick is set on described voussoir；Described flexible member is arranged on elastic shelf, and contacts with guiding voussoir；The leading flank of described safety gear block is fixed with baffle plate, and baffle plate is provided with gathering sill, is fixed with guide finger on the voussoir of gathering sill opposite position, and guide finger passes gathering sill.
The one side that aforesaid voussoir contacts with cage guide is provided with anti-skidding teeth.
Aforesaid gathering sill is for being obliquely installed, and incline direction is consistent with guiding ball.
Aforesaid guide finger is cylindrical guide pin.
Aforesaid each voussoir is provided with two guide fingers.
The arragement direction of aforesaid two guide fingers is consistent with gathering sill.
Aforesaid flexible member is c-type leaf spring.
The beneficial effect that the present invention is reached:
The progressive safety gear of the present invention is additionally arranged gathering sill and guide finger, makes voussoir have good guidance quality during moving up and down.And the voussoir of the present invention is provided with anti-skidding teeth, good antiskid effect on the occlusal surface of cage guide, it is ensured that the effect of stop.
Accompanying drawing explanation
Fig. 1 is the structural representation of the progressive safety gear of the present invention.
Detailed description of the invention
The invention will be further described below in conjunction with the accompanying drawings.Following example are only used for clearly illustrating technical scheme, and can not limit the scope of the invention with this.
As it is shown in figure 1, the elevator progressive safety gear of the present invention, including safety gear block (not demonstrating in accompanying drawing), stick 2, voussoir 7, guide voussoir 10, flexible member 3, elastic shelf 4, guide ball 8, cage guide 1.Concrete, voussoir 7 and guide voussoir 10 and be positioned at safety gear block, voussoir 7 is up-narrow and down-wide trapezoidal, and voussoir 7 is close to cage guide 1, and the one side that voussoir 7 contacts with cage guide 1 is provided with anti-skidding teeth.Guide and between voussoir 10 and voussoir 7, set guiding ball 8, and guide the face keeping parallelism that voussoir 10 is relative with voussoir 7.Stick 2 is set on voussoir 7.Flexible member 3 is arranged on elastic shelf 4, and contacts with guiding voussoir 10；Preferably, flexible member 3 is c-type leaf spring.
The leading flank of safety gear block is fixed with baffle plate 9, and baffle plate 9 is provided with gathering sill 5, is fixed with guide finger 6 on the voussoir 7 of gathering sill 5 opposite position, and guide finger 6 is through gathering sill 5.Move up and down in gathering sill 5 with voussoir 7 when voussoir 7 moves up and down, play good guidance quality.
Gathering sill 5 is for being obliquely installed, and incline direction is consistent with guiding ball；Guide finger 6 is cylindrical guide pin.
Preferably, each voussoir is provided with two guide fingers, and the arragement direction of two guide fingers is consistent with gathering sill.
The operation principle of the present invention is: mention when voussoir is manipulated by bar, it is fitted on cage guide and plays braking action, thrust is passed to guide voussoir by voussoir by molgogger, guide device on rear side of voussoir to have elastic component, the pressure making voussoir act on cage guide is provided with certain elasticity, produces the softest stop effect.Voussoir is provided with anti-skidding teeth, good antiskid effect on the occlusal surface of cage guide, it is ensured that the effect of stop.
The above is only the preferred embodiment of the present invention; it should be pointed out that, for those skilled in the art, on the premise of without departing from the technology of the present invention principle; can also make some improvement and deformation, these improve and deformation also should be regarded as protection scope of the present invention.
