Caliper 1 adopts Plate Welding to make, and the middle part of caliper 1 is vertically provided with slideway, and cage guide passes from slideway.
Fixing voussoir comprises fixes voussoir 5, right fixing voussoir 6 along the symmetrically arranged left side of cage guide, the two is hem width, ladder structure of right angle short below, the medial surface i.e. one side of close cage guide of the two is trapezoidal inclined-plane, and inclined-plane slopes inwardly from the bottom to top.Left fixing voussoir 5, right fixing voussoir 6 are fixed in caliper 1.
Slide assemblies is divided into left slide assemblies, right slide assemblies, left slide assemblies comprises the left roller guide 7 be fixed on through bolt on left fixing voussoir 5, be positioned at the needle plate that rolls left that left roller guide 7 can slide along its bearing of trend, left roller guide 7 is obliquely installed, and the direction of tilt that the inclined-plane of voussoir 5 is fixed on direction of tilt and a left side is identical.Right slide assemblies comprises the right roller guide 8 be fixed on through bolt on right fixing voussoir 6, be positioned at the right needle roller bearing plate that right roller guide 8 can slide along its bearing of trend, right roller guide 8 is obliquely installed, and the direction of tilt that the inclined-plane of voussoir 6 is fixed on direction of tilt and the right side is identical.
Sliding wedge is divided into left sliding wedge 9, right sliding wedge 10, the two is the ladder structure of right angle of short, the lower hem width in top, namely the two lateral surface is trapezoidal inclined-plane away from the one side of cage guide, inclined-plane slopes inwardly from the bottom to top, and direction of tilt is identical with the direction of tilt on the inclined-plane of fixing voussoir.The outside of left sliding wedge 9 is positioned at left roller guide 7 and contacts with the needle plate that rolls left, the outside of right sliding wedge 10 is positioned at right roller guide 8 and contacts with right needle roller bearing plate, and the needle plate that rolls left, right needle roller bearing plate make left sliding wedge 9, right sliding wedge 10 to slide along the bearing of trend of left roller guide 7, right roller guide 8 neatly.Under the effect of deadweight, left sliding wedge 9, right sliding wedge 10 are in bottom respectively, have spacing between medial surface and cage guide.
The inner side of left sliding wedge 9, right sliding wedge 10 is fixed with to projecting inward left slipper 11, right slipper 12 respectively, left slipper 11, right slipper 12 adopt carbon fiber to make, there is high strength and high-modulus, thermal expansion coefficient is little, good corrosion resistance, under elevator normal operating condition, the medial surface of left slipper 11, between the medial surface of right slipper 12 and cage guide, there is spacing.
Shift mechanism comprises slide plate 3, lifting rod 2, and slide plate 3 is fixed on the rear side of left sliding wedge 9, right sliding wedge 10, and lifting rod 2 passes slide plate 3 and connects firmly with slide plate 3.
U-shaped leaf spring 4 is positioned at the rear side of left fixing voussoir 5, right fixing voussoir 6, two sidewalls of U-shaped leaf spring 4 lay respectively at the left side wall of caliper 1 and a left side fix voussoir 5 lateral surface between, the right side wall of caliper 1 and the right side fix between the lateral surface of voussoir 6, the left side wall of U-shaped leaf spring 4, caliper 1, left fixing between voussoir 5 connect firmly through bolt, and the right side wall of U-shaped leaf spring 4, caliper 1, right fixing between voussoir 6 connect firmly through bolt.
The working process of the present embodiment is as follows:
When elevator is in normal operating condition, this safety tongs is failure to actuate, and left sliding wedge 9, right sliding wedge 10 are all positioned at bottom, now the medial surface of left slipper 11, between the medial surface of right slipper 12 and cage guide, there is gap.When elevator break down car drop fast and speed reach velocity limiter setting running velocity time, velocity limiter starts, now safety tongs starts action, velocity limiter mentions left sliding wedge 9, right sliding wedge 10 by shift mechanism, left sliding wedge 9, right sliding wedge 10 move up along left roller guide 7, right roller guide 8 respectively, till the medial surface of left slipper 11, the medial surface of right slipper 12 clamp cage guide firmly, make lift car stop motion.Because left slipper 11, right slipper 12 all adopt carbon fiber to make, carbon fiber is a kind of high-temperature fibre with high strength and high-modulus, its thermal expansion coefficient is little, good corrosion resistance, when the command speed of elevator is more than 4m/s, breaks down when dropping fast, slipper and the cage guide contact wear of high strength are little, can ensure lift car stop motion, left slipper 11, right slipper 12 enhance the deceleration and stopping performance of this safety tongs, extend the service life of safety tongs.
