Description
Technical field:
The utility model relates to elevator accessory technical field, is specifically related to the progressive elevator safety gear that a kind of safety is high.
Background technology:
Safety tongs is the important safety parts of lift facility, can elevator overspeed and out of control time play the vital function of safety control, can say, just because of appearance and the development of safety tongs, just make elevator become the requisite vertical transport instrument of a kind of skyscraper.
The action of safety tongs device makes rope-clamping pliers clamp governor rope by velocity limiter action, along with car runs downwards, governor rope lift safety tongs link mechanism, the action of safety tongs link mechanism, drive safety tongs braking element and guide rail contact, the safety tongs on guide rail both sides is clamped on guide rail simultaneously, reaches car stop.Safety tongs is generally arranged on car bottom girder or two heel posts, primarily of compositions such as clamp block, voussoir, lifting rod and the shift mechanisms being arranged on car entablatrance.Corresponding safety switching apparatus action, makes towing machine stop operating simultaneously.When safety tongs is failure to actuate, voussoir and working face of guide rail keep the gap of 2 ~ 3mm.Safety tongs two side clearance is wanted evenly, can make the reliable stop of car during action on guide rail.
But the structure due to current safety tongs also has some unreasonable parts, cause its often easy et out of order, fault cause is complicated and changeable, and the factor inspiring its misoperation is also more, therefore there is certain potential safety hazard, have serious consequences likely to elevator and passenger.
Utility model content:
The purpose of this utility model is to provide the high progressive elevator safety gear of a kind of safety, and its design science is reasonable, and good braking effect, can make the reliable stop of car on guide rail during safety action, and reduce fault rate, safety is high.
In order to solve the problem existing for background technology, the utility model is by the following technical solutions: it comprises joystick, safety tongs main body, main pincers block, secondary pincers block, fine adjustment screw, safe tong arm, balance spring mounting bracket, balance spring, mounting bracket, rear side and the top of safety tongs main body are fixedly installed mounting bracket, safe tong arm symmetry is fixedly mounted on the both sides of safety tongs main body, all fine adjustment screw is installed on front side of the junction of two safe tong arms and safety tongs main body, a groove is provided with on front side of safety tongs main body, in this groove, symmetry is installed with a pair main pincers block, between main pincers block, symmetry is installed with a pair secondary pincers block, secondary pincers block upper end is connected with joystick.
The opposite face of described pair pincers block is evenly provided with anti-skidding teeth.
Principle of the present utility model is: can regulate the secondary distance clamped between block by adjustment fine adjustment screw, and make the distance of its both sides maintain balance, symmetry, zero-error when ensureing to clamp, ensures safety.The occlusal surface of secondary pincers block is provided with anti-skidding teeth, good antiskid effect, ensure that the effect of stop.
The utility model design science is reasonable, and good braking effect, can make the reliable stop of car on guide rail during safety action, and reduce fault rate, safety is high.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present utility model;
Reference numeral: joystick 1, safety tongs main body 2, main pincers block 3, secondary pincers block 4, fine adjustment screw 5, safe tong arm 6, balance spring mounting bracket 7, balance spring 8, mounting bracket 9.
Detailed description of the invention:
With reference to Fig. 1, this detailed description of the invention is by the following technical solutions: it comprises joystick 1, safety tongs main body 2, main pincers block 3, secondary pincers block 4, fine adjustment screw 5, safe tong arm 6, balance spring mounting bracket 7, balance spring 8, mounting bracket 9, the rear side of safety tongs main body 2 and top are fixedly installed mounting bracket 9, safe tong arm 6 symmetry is fixedly mounted on the both sides of safety tongs main body 2, on front side of the junction of two safe tong arms 6 and safety tongs main body 2, fine adjustment screw 5 is all installed, a groove is provided with on front side of safety tongs main body 2, in this groove, symmetry is installed with a pair main pincers block 3, between main pincers block 3, symmetry is installed with a pair secondary pincers block 4, secondary pincers block 4 upper end is connected with joystick 1.
The opposite face of described pair pincers block 4 is evenly provided with anti-skidding teeth.
The principle of this detailed description of the invention is: can regulate the secondary distance clamped between block 4 by adjustment fine adjustment screw 5, and make the distance of its both sides maintain balance, symmetry, zero-error when ensureing to clamp, ensures safety.The occlusal surface of secondary pincers block 4 is provided with anti-skidding teeth, good antiskid effect, ensure that the effect of stop.
This detailed description of the invention design science is reasonable, and good braking effect, can make the reliable stop of car on guide rail during safety action, and reduce fault rate, safety is high.
