Therefore, the technical solution of the utility model is as follows：
A kind of novel elevator safety tongs, including the clamp block being arranged on the guide rail, the clamp block inner hollow are described to lead
Rail runs through the clamp block, and be provided with two or so inside the clamp block is symmetrically oriented to matrix, the guiding with the guide rail relatively
Leaned between matrix into being provided with two brake caliper blocks that the guiding matrix can be coordinated to slide, two brake caliper block phases at the guide rail
Symmetrical to the guide rail, the brake caliper block is provided with the pull bar for being used for driving slip, the guiding matrix and the pincers
Clamping action spring is provided between the left and right sidewall of seat, the pull bar drives the brake caliper block to move up, and coordinates and is led described in compressing
To matrix, under the elastic force effect of clamping action spring so that brake caliper block direction guiding rail clamps, and passes through frictional force car system
It is dynamic to stop.
In the above-mentioned technical solutions, safety tongs of the present utility model is simple in construction firm, and good integrity, linkage is strong, fortune
Dynamic safety and stability, is easily resetted, good braking effect, and the damage to equipment room is lacked, and the pull bar is driven in the brake caliper block
Move, coordinate and oppress the guiding matrix, under the elastic force effect of clamping action spring so that brake caliper block direction guiding rail clamps, and leads to
Crossing frictional force causes car braking to stop.
As the preferred of above-mentioned technical proposal, the opposite side of the effect matrix is respectively provided with the guiding moved closer to upwards
Inclined-plane.
As the preferred of above-mentioned technical proposal, the brake caliper block has and the guiding towards the effect matrix side
Inclined-plane is to corresponding sliding bevel.
As the preferred of above-mentioned technical proposal, if being additionally provided with the gap acted between matrix and the brake caliper block
Dry milling pearl, the ball are tangent with the guiding surface and sliding bevel respectively.
As the preferred of above-mentioned technical proposal, the ball is disposed with three along sliding bevel direction, is uniformly arranged in
On the sliding bevel.
As the preferred of above-mentioned technical proposal, in addition to the resetting-mechanism at the top of the brake caliper block is arranged on, it is described multiple
Position mechanism includes being arranged on the actuator at the top of the brake caliper block, and the upper end of the actuator is connected with buffer stopper, described
Buffer stopper is used to act on the roof contradicted in the clamp block.
As the preferred of above-mentioned technical proposal, the actuator is hydraulic cylinder or cylinder.
As the preferred of above-mentioned technical proposal, the connecting rod between the actuator and the buffer stopper is externally provided with buffering elastic
Spring.
The beneficial effects of the utility model：Simple in construction firm, good integrity, linkage is strong, stabilization safe for operation, easily
Reset, good braking effect, and the damage to equipment room is lacked, service life length, ball uses the frictional force for make it that reduction acts,
Play a part of soft stop so that reset more convenient.
