Transmission mechanism lift sliding wedge 14 and sliding wedge 14 under the cooperation of the needle roller of needle roller bearing plate 13 along guide rail voussoir 12 guide rail to
Upper movement, untill clamping face, the clamping face of brake block 15 until sliding wedge 14 firmly clamp cage guide, makes elevator
Car stop motion.
But, above-mentioned existing structure safety tongs not only complex structure, installation inconvenience, and the reset of its needle roller bearing plate 13 needs people
Work is operated, it is therefore desirable to this improvement.
Utility model content
In order to solve the above technical problems, the utility model automatically resets safety tongs there is provided one kind, it is more convenient to realize
Mounting structure and needle roller bearing plate auto-reset function.
To reach above-mentioned purpose, the technical solution of the utility model is as follows：
One kind automatically resets safety tongs, including：Slide assemblies and brake block are symmetrically installed with caliper, the caliper；
The slide assemblies include：Sliding wedge, needle roller bearing plate and the guide groove cover plate for being symmetrically mounted on the caliper both sides, two
Guide groove is offered described in side on guide groove cover plate, the guide groove of guide groove cover plate is symmetrical arranged described in both sides, and the guide groove is by lower
The upper setting that slopes inwardly；The two ends of the sliding wedge are set described in both sides in guide groove by deflector roll card, and the needle roller bearing plate is slided
It is arranged in guide groove cover plate described in both sides and laminating parallel with the sliding wedge；
The slide assemblies also include extension spring, and one end of the extension spring is fixed on the bottom of the guide groove cover plate, the other end
It is fixed on the needle roller bearing plate.
It is preferred that, it is parallel on guide groove cover plate described in per side to offer two guide grooves, the two ends of the sliding wedge
Set by deflector roll card in the guide groove of inner side, the two ends of the needle roller bearing plate are set in the guide groove of outside by deflector roll card.
It is preferred that, the extension spring has two, and one end of two extension springs is respectively symmetrically fixed on guide groove cover plate described in both sides
Bottom.
By above-mentioned technical proposal, the safety tongs that automatically resets that the utility model is provided, it has such as compared with prior art
Under superior part：
1. the guide rail formed compared to prior art by the inside bending of guide rail voussoir, the utility model uses guide barrel construction
It may insure accuracy and stability that sliding wedge is oriented to, it is to avoid sliding wedge occur and occur tilting and the bad shape such as depart from
Condition；
2. by setting extension spring, after sliding wedge resets, needle roller bearing plate can be resetted automatically by the effect of extension spring,
Ensure that needle roller bearing plate is in minimum point during braking next time, needle roller sheet reset is convenient and swift.
