Detailed Description
The technical scheme of the patent is further described in detail below with reference to the specific embodiments.
Embodiments of the present patent are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals refer to the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary only for explaining the present patent and are not to be construed as limiting the present patent.
As shown in figures 1-3 of the drawings,
The utility model provides an overspeed detection and anti-falling safety device, including stand 1, guide rail 2, lift safety tongs 3 and crane 4, guide rail 2 set up on stand 1, lift safety tongs 3 and guide rail 2 cooperation, crane 4 is fixed on lift safety tongs 3 and with guide rail 2 upper and lower sliding connection, stand 1 bottom is fixed to be provided with overspeed governor 5, stand 1 top is provided with overspeed governor auxiliary idler 6, be provided with lift link mechanism 7 on the lift safety tongs 3, lift link mechanism 7 includes lift lever 71, lift lever 71 one end is connected on lift safety tongs 3 and the other end articulates there is connecting rod 72, the one end that the connecting rod 72 kept away from lift lever 71 articulates there is control trace 73, the one end that the connecting rod 72 was kept away from is kept away from about trace 73 is fixed at cargo carrying platform 8, cargo carrying platform 8 is fixed on crane 4, the upper portion of lift lever 71 is provided with upper connecting bolt 74, the lower part of lift lever 71 is provided with down connecting bolt 75, be provided with wire rope 9 on overspeed governor 5, wire 9's lower extreme bypass speed limiter 5 is connected with wire rope auxiliary idler 6 with lower connecting bolt 75, wire rope 9's upper end bypass upper end and upper connecting bolt 74.
The guide rail 2 is a T-shaped guide rail. The lifting safety tongs 3 are provided with a triggering clamping structure and a triggering sensor, and the common lifting safety tongs in the market can be selected.
When the descending speed of the cargo carrying platform 8 is too high, the steel wire rope 9 can automatically trigger the speed limiter 5 to clamp the structure, and the speed limiter 5 clamps the steel wire rope 9 to prevent the steel wire rope 9 from continuously rotating.
