Fig. 2 is the dimensional structure diagram of elevator safety gear in Fig. 1；
Fig. 3 is the planar structure schematic diagram under another embodiment of elevator safety gear of the present invention.
Specific implementation mode
Following is a specific embodiment of the present invention in conjunction with the accompanying drawings, technical scheme of the present invention will be further described,
However, the present invention is not limited to these examples.
Such as Fig. 1,2, elevator safety gear of the present invention includes safety gear block 1, operating lever 2, main pincers block 3, secondary pincers block 4, orienting roll
Pearl 6.Two secondary pincers blocks 4 are arranged in the safety gear block 1 so that pass through 8 both sides of cage guide of safety gear block 1 respectively with
Two secondary pincers blocks 4 contact.Both sides in the safety gear block 1 are symmetrical arranged two main pincers blocks 3.The main pincers block 3 and the pair
It is equipped between pincers block 4 and is oriented to ball 6.The secondary pincers block 4 is equipped with operating lever 2.Lifted by operating lever 2 when pair clamps block 4, is fitted in
Braking action is played on cage guide 8, thrust is passed to main pincers block 3 by pair pincers block 4 by being oriented to ball 6.
Specifically, the main pincers block 3 is set to as guide forceps block on safety gear block 1.The main pincers block 3 is towards the secondary pincers
The one side of block 4 is main inclined plane.The secondary pincers block 4 moves up and down under the guiding of main pincers block, and the secondary pincers block 4 is towards the main pincers
The one side of block 3 is secondary inclined-plane.Wherein, the main inclined plane is arranged in parallel with the secondary inclined-plane.The guiding ball 6 is set to two inclined-planes
Between.In order to ensure pair pincers block is steadily moved relative to main pincers block, that is, ensure that two inclined-planes are protected always in pair clamps block moving process
Parastate is held, the gap uniformity in guide rail both sides is clamped to ensure safety, guide groove is provided on the main inclined plane of the main pincers block 3,
6 part of guiding ball is placed in guide groove, and partial action is in the secondary inclined-plane.It is oriented to constraint of the ball 6 in guide groove
Under, it rolls in one direction, and kept on the same line between multiple guiding balls.
The secondary pincers one side of the block 4 towards cage guide is the vertical plane parallel with cage guide, the vertical plane
It is equipped with damping layer 7.Using damping layer so that safety tongs finally quickly rests on cage guide.The damping layer 7 be with
The damping layer of several evenly arranged kerves.The depth of rebate of each kerve is 1mm, groove width 1mm, multiple kerve compact neat rows
Cloth together, the frictional force between block 4 and cage guide is clamped with raising pair.
In order to avoid stress deviates operating lever in operation, the safety gear block 1 is equipped with groove 11, and the operating lever 2 is held
It is placed in the groove 11.On the one hand groove 11 protects operating lever maloperation, another aspect constraint manipulation bar 2 is in effective direction
Interior effect.But groove is substantially constraint manipulation bar to be acted in useful direction, still can not be accurately oriented to.Fig. 3 shows this
Structural schematic diagram under another embodiment of invention elevator safety gear.The main pincers block 3 is at the position for being higher by the secondary pincers block 4
Equipped with guide part 31, the operating lever 2 is placed in across the guide part 31 in groove 11.Under one example, the guide part
31 extension block to extend from the main pincers block 3 to 8 direction of cage guide, the extension block is interior to have longitudinal circle for running through its block
Post holes, operating lever may pass through cylindrical hole.Under another example, the guide part is the ring-like lead ring with opening, the opening face
Towards 8 direction of cage guide.Under said program, operating lever acts in the axial direction, is not easy to shift in a circumferential direction.Same time delay
The setting for stretching block or annular lead ring also further constrains secondary pincers block relative to the displacement of main pincers block movement, that is, occurs tight
The distance that safety tongs can be braked when anxious stop.The factors such as the tolerance for reduction assembly building cause safety tongs effectively to use, the guiding
Portion 31 is integrally formed with main pincers block 3.
Specific embodiment described herein is only an example for the spirit of the invention.Technology belonging to the present invention is led
The technical staff in domain can make various modifications or additions to the described embodiments or replace by a similar method
In generation, however, it does not deviate from the spirit of the invention or beyond the scope of the appended claims.
