Detailed Description
The invention is further described with reference to the following figures and examples:
the first embodiment is as follows: referring to fig. 1 and 2, a counterweight safety gear device comprises a counterweight frame 1 and a counterweight 2 arranged in the counterweight frame 1, wherein the outer walls of two sides of the counterweight frame are respectively provided with a safety gear 3, two groups of safety gears are connected through a lifting mechanism 4, the lifting mechanism comprises a rotating shaft 5, a connecting rod 6 and a connecting mechanism, two ends of the rotating shaft are rotatably arranged in the counterweight frame 1, the connecting rod is arranged on the side part of the rotating shaft in parallel, the middle part of the connecting rod is connected with the middle part of the rotating shaft through the connecting mechanism, and two ends of the connecting rod are respectively connected with lifting rods 8 of the two groups of safety gears 3 through a connecting plate 7; and two ends of the rotating shaft are respectively sleeved with a torsion spring 9, and the torsion springs push the rotating shaft to rotate so that the connecting rod moves downwards.
In this embodiment, the wire rope can be connected with the speed limiter through the safety gear, if say the counterweight downward speed is too fast, after the overspeed, will draw the work of safety gear through carrying the mechanism and block the counterweight guide rail. In the process, the connecting rod rotates around the rotating shaft through the connecting mechanism, the torsion spring is twisted, the connecting rod moves upwards, the lifting rod is driven to ascend through the connecting plate, the safety tongs are lifted, the safety tongs are clamped on the counterweight guide rail, and counterweight limiting is completed. If say that need remove safety tongs's spacing, it goes upward to heavily when only needing to overhaul for when rising to heavily, to the decurrent dynamics just disappeared because torsional spring self restoring force like this, will promote the pivot and reset, the pivot passes through coupling mechanism and drives the connecting rod downstream, the connecting rod then promotes safety tongs's lifting rod downstream through the connecting plate, make safety tongs open, it is spacing to remove automatically, efficient, of high quality, the security is better, also be convenient for remove safety tongs's spacing. And the lifting mechanism is arranged inside the counterweight housing, so that the occupied space is reduced, the cost is lower, and the safety factor is higher.
