Description

Technical Field

[0002] An elevator safety tong is a safety protection device for an elevator. The elevator safety tong device is a safety device that, under the control of a speed limiter, when the elevator speed exceeds the limit speed set by the elevator speed limiter, or in the case of the breakage and slack of the suspension rope, urgently stops the car and clamps it on the guide rail.

[0003] After retrieval, the existing patent (application number: 202220652162.3) discloses an elevator safety tong lifting device, including a lifting seat. A buffer cylinder is fixedly connected to the top of the lifting seat. A water-based shock-absorbing plate is arranged on the inner wall of the buffer cylinder. A guiding rod is slidably connected to the inner surface of the buffer cylinder. A fixing table is movably sleeved on the outer surface of the guiding rod. A tightening bolt is arranged on the outer surface of the guiding rod. A seat platform is fixedly connected to the top of the lifting seat. For this elevator safety tong lifting device, when the safety tong brakes and the pull rod is subjected to a certain degree of instantaneous impact force, the guiding rod will squeeze the water-based shock-absorbing plate along the inner wall of the buffer cylinder, and the instantaneous impact force received by the guiding rod can be released. At the same time, the shock-absorbing buffer rubber pad can absorb part of the noise generated by the components and effectively relieve the problem of spring weakness, and the damping sound-insulating felt absorbs the noise. Furthermore, through buffer noise reduction and flexible speed reduction, the panic of passengers in an emergency can be reduced. The inventor found the following problems in the prior art during the implementation of the present utility model:
