Unhooking resetting device and unhooking resetting method

Abstract

The invention discloses an unhooking resetting device and an unhooking resetting method. The unhooking resetting device comprises a safety pin inserting and removing device, a swing beam rotating device, a front swing arm I, a rear swing arm I, a front swing arm II, a rear swing arm II, a middle fixing lug plate and an opening and closing hydraulic oil cylinder, wherein the safety pin inserting and removing device comprises a latch hydraulic oil cylinder, a middle flange and a safety pin; the latch hydraulic oil cylinder and the safety pin are separately arranged at two sides of the middle flange and are connected through rotating hinge points; the swing beam rotating device comprises a hydraulic motor, a transmission shaft, a rotating shaft and a swing beam; the transmission shaft is mounted in a mounting flange; the rotating shaft is mounted on the swing arm II; one end of the transmission shaft is connected with the hydraulic motor, the transmission shaft is sleeved with the sliding sleeve, and the other end of the transmission shaft extends into a screw hole in the front end of the rotating shaft; the sliding sleeve is in embedded connection with the rotating shaft through trapezoidal teeth on the end surface; and the sliding sleeve is connected with a stirring connecting rod. According to the unhooking resetting method, rapid and reliable unhooking can be achieved, rapid resetting can be achieved after unhooking, the unhooking resetting process can be simplified, and the test safety can be improved.

Description

technical field [0001] The invention belongs to the technical field of free fall test of an elevator test device, and relates to a decoupling reset device and a decoupling reset method for the free fall test of an elevator test tower. Background technique [0002] Unhook reset device (such as figure 1 Shown) is the key actuator for the free fall test of the elevator test tower, connected to the upper guide device ( figure 1 Not shown in ) and the lower part of the test load ( figure 1 The falling member in is the test load). Unhook reset device (such as figure 1 Shown) includes front and rear two swing arms I13, front and rear two swing arms II 14, a fixed ear plate 11 in the middle, an opening and closing hydraulic cylinder 12 in the middle, safety pin 5, swing beam 10, fixed pin 15; I13 and the top of the swing arm II14 are connected together through the fixed ear plate 11; the middle parts of the swing arm I13 and the swing arm II14 are respectively connected with the...

Problems solved by technology

[0003] At present, the existing unhook reset device and unhook reset method for the free fall test of the elevator test tower, the plugging action of the safety pin 5 and the movement of the swing beam 10 Rotation reset action, generally adopts manipulator plus manual operation, the cost is high, after each uncoupling action, the hovering position of the swing arm and the swing beam 10 is not the same, the manipulator moving according to the predetermined trajectory may not be able to achieve the best reset effect; and In the unhooking reset process, when unhooking, it is necessary to use the manipulator to pull out the safety pin 5 first, and then start the opening and closing hydraulic cylinder 12, and its piston rod is stretched out, and the swing arm I13 is pushed out to separate from the swing arm II 14, and one end of the swing beam 10 Fixed on II 14, the other end of the swing beam 10 is disengaged from the fixed pin 15 on the swing arm I13 to hang down, and the falling member on the swing beam 10 falls to complete the decoupling action; After the position of the pull rod 16 of the falling member, the fixed pin 15 needs to be pulled out first, and the swinging beam 10 is used to level it with the manipulator, and then the fixing pin 15 is inserted back, and after the swinging beam 10 rests on the fixing pin 15 , and then use the manipulator to insert the safety pin 5, so that the reset after decoupling can be realized smoothly; the whole decoupling and reset process is complicated and cumbersome, and once a fault occurs, it will be labor-intensive and highly dangerous
