Detailed description of the invention
Embodiment
A kind of elevator progressive safety gear, structure as shown in Figure 2, comprises caliper 1, slide assemblies, sliding wedge 3, slipper 6.
Caliper 1 adopts cast steel to make, and the middle part of caliper 1 is vertically provided with slideway, and cage guide passes from slideway, and the left side of slideway is slipper 6, and right side is sliding wedge 3.The sidewall 11 be connected with the slide assemblies i.e. bottom right, left side wall upper left of caliper 1 is obliquely installed.
Slide assemblies comprises roller guide 2, needle roller bearing plate 4.Roller guide 2 is the channel-shaped structure of upper and lower both ends open, and the horizontal section of groove is C shape (also can for [shape, the incline U-shaped or semicircle etc. put can with the shapes of the class similar C-shaped replaced).As shown in Figure 3, roller guide 2 comprises base plate 21 and two side plates 22, base plate 21 laminating is fixed on the oblique sidewall 11 of caliper 1, two side plates 22 lay respectively at the both sides of base plate 21 and base plate 21 one-body molded, the free end of biside plate 22 is respectively with the flange 23 extended internally.
Needle roller bearing plate 4 is positioned at roller guide 2, can slide along the bearing of trend of roller guide 2.In order to avoid needle roller bearing plate 4 directly contacts with base plate 21, between needle roller bearing plate 4 and base plate 21, be also provided with backing plate 5.
Sliding wedge 3 is the right-angled trapezium shape structure of short, the lower length of side in top, its medial surface is parallel with slideway, and lateral surface is inclined-plane, and this inclined-plane tilts in the same way with the sidewall 11 of caliper 1 and parallels, sliding wedge 3 is connected with transmission device, and transmission device is controlled and action by velocity limiter.The front side wall of sliding wedge 3, rear wall are respectively equipped with chute 31, two flange 23 are stuck in two chutes 31, to make the bevelled side of the band of sliding wedge 3 be positioned at roller guide 2 and contact with needle roller bearing plate 4, needle roller bearing plate 4 makes sliding wedge 3 to slide along the bearing of trend of roller guide 2 neatly.Sliding wedge 3 is in bottom, has spacing between its medial surface and cage guide.
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 sliding wedge 3 is positioned at bottom, now sliding wedge 3, between slipper 6 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 sliding wedge 3 by lift transmission device, sliding wedge 3 moves up along roller guide 2, clamping face and the medial surface of sliding wedge 3 contact with cage guide, and friction also self-locking, makes lift car stop motion.
