Embodiment 1

[0019] Such as figure 2 with Figure 4 As shown, the bidirectional braking safety gear of the present invention includes an upper shell 91, a lower shell 92, a left shell 93, a right shell 94, a right pull rod 10, a right braking part 20, a right needle roller seat 30 and a right needle roller plate 31. The upper case 91 is provided with an upper case U hole 91a, and the lower case 92 is provided with a lower case U hole 92a. The upper casing U hole 91a and the lower casing U hole 92a are covered with the elevator guide rail 8 , and also include the left tie rod 40 , the left braking part 50 , the left needle roller seat 60 and the left needle roller plate 61 .

[0020] The lower part of the right tie rod 10 passes through the right oblong hole 91b of the upper shell and is fixedly connected with the upper end surface of the right brake part 20 . The top of the right tie rod 10 is fixedly connected to the bottom of the right connecting rod 11, and the upper part of the righ...

Embodiment 2

[0033] Such as image 3 As shown, the difference between the second embodiment and the first embodiment is that the left cover 71 and the right cover 72 are provided on the front sides of the left shell 93 and the right shell 94 . The left cover plate 71 is fixedly connected with the left needle roller seat 60 . The right cover plate 72 is fixedly connected with the right needle roller seat 30 . A left pin 58 is provided on the front end surface of the left brake part 50 . The left cover plate 71 is provided with a left elongated hole 71a matched with the left pin 58, and the left pin 58 is movably connected with the left elongated hole 71a. The left elongated hole 71 a is parallel to the left end surface of the left brake part 50 . A right pin 28 is provided on the front end surface of the right brake part 20 . The right cover plate 72 is provided with a right elongated hole 72a matched with the right pin 28, and the right pin 28 is movably connected with the right elonga...

Abstract

The invention provides two-way brake safety tongs, and relates to a safety device of an elevator, in particular to progressive safety tongs used for the elevator. The two-way brake safety tongs are simple in structure and low in cost, and can be braked downwards and upwards. When the two-way brake safety tongs need to be braked downwards, a right pull rod is pulled upwards through external force, a right brake part is pulled upwards, a right brake plate on the left end face of the right brake part makes contact with a guide rail of the elevator, the right brake part is clamped between the guide rail of the elevator and a right rolling needle plate base through tensile force of the external force and friction provided by the guide rail of the elevator, and therefore the effect of braking the two-way brake safety tongs is achieved; the safety tongs are fixedly connected with an elevator car of the elevator, and therefore the effect of braking the elevator car of the elevator is achieved. When the two-way brake safety tongs need to be braked upwards, the effect of braking the elevator car of the elevator is achieved in the same way.

Description

technical field [0001] The invention relates to a safety device of an elevator, in particular to a progressive safety gear used by an elevator. Background technique [0002] Existing safety gear devices produced both at home and abroad are mostly made up of main parts such as caliper body, roller parts, wedges. my country's utility model progressive safety gear, the application number is 201120234950.2, and the application date is 2011.7.5, which discloses a progressive safety gear, such as figure 1 Shown includes a bracket 1', a fixed wedge 3' and a slider 4'. A fixed slot 101' is opened on the upper end of the bracket 1' and above the fixed wedge 3'. The fixed The upper part of the wedge 3' is provided with a first convex shoulder 301', the first convex shoulder 301' fits with the fixed slot 101', is located at the upper end of the bracket 1' and is located on the slider 4' is provided with a chute 102', and the upper part of the slider 4' is provided with a second conve...
