The invention relates to the technical field of elevator braking equipment, and discloses an elevator safety gear which comprises a base, a sliding rail obliquely arranged on the base, a movable wedge block arranged on the sliding rail in a sliding mode and a fixed wedge block fixed to the base, and the movable wedge block can be driven by a lifting device to move upwards along the sliding rail. A transverse fixing rod extending front and back is arranged at the bottom of the sliding rail, a hook is arranged on the end face, matched with the sliding rail, of the movable wedge block, and the hook and the transverse fixing rod are connected through a reset tension spring. According to the elevator safety tongs, the reset spring is ingeniously arranged in the sliding rail, the safety tongs can reset after braking without the help of a lifting device or other devices, and due to the fact that the reset spring is designed in the sliding rail of the safety tongs, an automatic reset structure does not need to be additionally matched in the lifting device; the lifting device can be designed to be simpler and more compact, and elevator layout design is facilitated.

    本发明涉及电梯制动设备技术领域,并公开了一种电梯安全钳,包括基座、倾斜设置在基座上的滑轨、滑动设置在滑轨上的活动楔块、以及固定在基座上的固定楔块,所述活动楔块能够在提拉装置的带动下沿着滑轨上移,使活动楔块与固定楔块共同对导轨进行钳刹,所述滑轨的底部设有前后延伸的横固定杆,所述活动楔块与滑轨配合的端面上设有挂钩,所述挂钩和横固定杆通过复位拉簧连接。本发明提供的电梯安全钳巧妙地在滑轨的内部设置复位弹簧,无需借助提拉装置或其他装置也可完成安全钳刹钳后复位,由于复位弹簧设计在安全钳的滑轨内部,所以提拉装置中无需额外搭配自动复位结构,提拉装置可以设计更加简单紧凑,有利于电梯布局设计。
