Detailed Description
The invention will be further described with reference to the following drawings 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.
Referring to fig. 2, two sides of the rotating shaft are respectively provided with a bolt 10, the torsion spring is sleeved on the end portion of the rotating shaft, one end of the torsion spring abuts against the outer edge surface of the bolt, and the other end of the torsion spring is clamped on the inner wall of the counterweight housing.
The arrangement of the bolts is adopted, so that the end part of the torsion spring can hook the rotating shaft conveniently, and the rotating shaft can return to the original position along with the return of the torsion spring along with the rotation.
Referring to fig. 1 and 2, the connecting mechanism includes a square frame 11 with a hollow structure, the number of the rotating shafts is two, the outer ends of the two groups of rotating shafts are respectively connected with the inner walls of the two sides of the counterweight housing in a rotating manner, and each group of torsion springs is sleeved on the outer end corresponding to the rotating shaft; the inner end of each group of rotating shafts is connected with the two sides of the rear end of the square frame; the inner ends of the two groups of connecting rods are connected with the two sides of the front end of the square frame, and the outer ends of the two groups of connecting rods are respectively connected with the lifting rods corresponding to the safety tongs through a connecting plate.
The left side and the right side of the square frame are respectively provided with two groups of square holes 12, the inner ends of the rotating shaft and the connecting rod are respectively provided with a square head 13, the rotating shaft and the connecting rod pass through the square heads and are inserted into the square holes correspondingly, and the square heads are locked with the square frame through locking bolts.
In this embodiment, all set up pivot, connecting rod into two sets ofly, connect through square frame, if a set of torsional spring goes wrong like this, or a set of safety tongs goes wrong etc. when needs the maintenance right, only need will correspond square head and square frame the junction dismantle the maintenance can, need not to carry the mechanism dismantlement with whole group, be convenient for maintain and change, also be convenient for install, the convenience is good, module piece installation and dismantlement change moreover, lower cost. Simultaneously, adopt quad slit and square head to be connected, when the pivot rotated like this, must drive square frame and enclose around the rotation of rotation, square frame's rotation also can drive the connecting rod along with rotating, guarantees the uniformity and the stability of linkage, when guaranteeing to carry and draw or relax, can make safety tongs pin to heavy guide rail or safety tongs and to heavy guide rail release the locking.
Referring to fig. 1 and 2, one end of one group of the connecting plates is connected with the lifting rod, and the other end is provided with a lifting arm 14. The lifting arm is convenient to be connected with a steel wire rope, so that the steel wire rope is connected with the speed limiter, the moving speed of the counterweight is guaranteed not to be overspeed, the safety tongs can be normally lifted and locked, and the use safety is guaranteed.
