Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
With reference to figure 1 and Fig. 2, hydraulic safe pincers drag link mechanism, comprises safety tongs 1, pull bar 2, connecting rod 3, connecting rod base 4, oil cylinder 5, cylinder rack 6 and car 7.Safety tongs 1 is connected with one end of pull bar 2, the other end of pull bar 2, connecting rod 3 all pass through unit's pin with oil cylinder 5 and are connected successively, and connecting rod 3 is arranged on connecting rod base 4, and oil cylinder 5 is arranged on oil cylinder seat 6, connecting rod base 4 and oil cylinder seat 6 are all arranged on car 7 and push up, and safety tongs 1 is arranged on bottom car 7.In addition, in order to allow work time more reliable, safety tongs 1, pull bar 2, connecting rod 3 and connecting rod base 4 are all two, are symmetricly set on oil cylinder 5 both sides.
With reference to figure 3 and Fig. 4, the riser 42 that connecting rod base 4 comprises base plate 41 and is fixedly connected with base plate 41, riser 42 is provided with groove 421, groove 421 and connecting rod 3 match, make connecting rod 3 can put into groove 421 and be arranged on riser 42, conveniently connect in addition, riser 42 is also provided with hole, make connecting rod 3 can sell passing hole with unit and be arranged in riser 42.
With reference to figure 5, cylinder rack 6 comprises lower plate 61, column 62 and panel 63, and column 62 one end is fixedly connected with lower plate 61, and the other end is fixedly connected with panel 63, and oil cylinder 5 is arranged on panel 63.
When needs utility model works, namely, when faults such as elevator generation stall or disconnected ropes, the oil cylinder 5 at this moment in cylinder rack 6 is started working, and the piston rod of oil cylinder 5 stretches out outward, down move in one end of drivening rod 3, now, because connecting rod base 4 becomes a fulcrum, the other end of connecting rod 3 then up moves, pull bar 2 is driven up to move, the safety tongs 1 be connected with pull bar 2 is tightened up, and the locked car 7 of safety tongs 1, elevator is stopped.And after fault is discharged, the piston rod of oil cylinder 5 is regained inward, up move in one end of drivening rod 3, now, because connecting rod base 4 becomes a fulcrum, the other end of connecting rod 3 then down moves, pull bar 2 is driven down to move, the safety tongs 1 be connected with pull bar 2 is relaxed, and safety tongs no longer pins car 7, and elevator just can run again.The utility model structure is simple, safe and reliable, and simple to operate, easy to maintenance.
Above-described is only embodiments more of the present utility model.For the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
