Detailed description of the invention
Below in conjunction with embodiment, this utility model is described in detail.
This utility model safety lock includes tripper, matrix, lock rope spring, centrifugal wheel, rope clamp support plate, rope clamp, lock rope swing arm, driven pulley and the front and rear covers of one.Wherein tripper is by driving plate promotion rope clamp and rope clamp support plate, and lock rope arm is locked in lock rope swing arm simultaneously, to reach safety lock unblock.The centrifugal wheel of safety lock is fixed on front and rear covers, can only rotate immovable, and steel wire rope is pressed on centrifugal wheel by driven pulley.This avoid steel wire rope movable type and can not effectively be close to centrifugal wheel, it is impossible to stable effective triggering locks rope swing arm.For avoiding steel wire rope to drive driven pulley to move, it is separated from centrifugal wheel, it is ensured that driven pulley continues to be pressed on fifth wheel steel wire rope, it is achieved fifth wheel reliable and stable.Centrifugal block for clutch use is fixed on and gets rid of on block base, and rotate around getting rid of block base two ends, get rid of block base center to be fixed on fifth wheel, the fixing pulling force of block spring is got rid of by setting, limit distance and speed that centrifugal block for clutch use is opened, it is ensured that after the fifth wheel of safety lock only reaches corresponding rotating speed, just can open centrifugal block for clutch use, trigger lock rope swing arm, locked steel wire rope.
Embodiment
In figure: matrix 1, front and rear covers 2, tripper 3, lock rope spring 4, rope clamp support plate 5, rope clamp 6, centrifugal wheel 7, rotating shaft 8, driven pulley rotating shaft 9, driven pulley support plate 10, driven pulley 11, preloading spring 12, lock rope swing arm 13, back-moving spring 14, centrifugal block for clutch use 15, get rid of block spring 16, get rid of block base 17, lock rope pretension spring 18, lock rope pin 19, handle 20, lock rope arm 21, drive arm 22, lock rope pin 23, guide plate 24, rotating shaft 25.
Safety lock design is with matrix for stress base matrix, Suo Sheng mechanism (rope clamp, rope clamp support plate, bearing pin) is connected by rotating shaft 25 and matrix, front and rear covers is bolted on matrix, remaining is non-stress-carrying part, and non-stress-carrying part is then fixed on front and rear covers by standard components such as bearing pin, bearing, bolt, springs.
As shown in the figure, in the present embodiment, rope clamp is limited in upper and lower rope clamp support plate, rope clamp support plate is fixed on matrix by rotating shaft, and can rotate upwardly and downwardly around the shaft, and rope clamp moves up and down along with the rotation of rope clamp support plate, do the action of opening and closing simultaneously, when opening, it is ensured that the smooth and easy operation of steel wire rope, locking steel wire rope after Guan Bi.
Centrifugal wheel is arranged on front and rear covers, is positioned at the lower end of rope clamp.Driven pulley is fixed on matrix, and rotates around the axis with driven pulley support plate, and preloading spring is pressed on driven pulley on centrifugal wheel.Centrifugal wheel self is only capable of pivoting, it is impossible to laterally move, it is ensured that tests the speed is reliable and stable.Tripper is arranged on front and rear covers, and the driving arm in this device contacts with rope clamp support plate, turning handle, is driven by main shaft and drives arm, and drives arm to promote rope clamp support plate and rope clamp to move downward, to open safety lock.Under normal operating conditions, along with steel wire rope moves in safety lock, centrifugal wheel can be driven to rotate, centrifugal block for clutch use and get rid of block base and can rotate together along with centrifugal wheel, and centrifugal block for clutch use can be flared out respectively centered by getting rid of block base two ends, get rid of block spring restriction centrifugal block for clutch use to be flared out, the i.e. rotating speed of centrifugal wheel must reach certain requirement, just be enough to open centrifugal block for clutch use, and triggers lock rope swing arm, open tripper to rope clamp support plate and the restriction of rope clamp so that safety lock fast lock rope.When centrifugal block for clutch use opens, certain cross force is applied for lock rope swing arm so that lock rope swing arm overcomes the restriction of back-moving spring, rotates around a bit, open rapidly tripper on front and rear covers.Contact with spacing bearing pin under lock rope swing arm normal condition, and under the effect of back-moving spring, be pressed on spacing bearing pin, to ensure the lock rope locked tripper of swing arm.Centrifugal block for clutch use is provided with guide plate, limits centrifugal block for clutch use maximum opening angle, set the initial fixing pulling force getting rid of block spring between two centrifugal block for clutch use, after the fifth wheel of guarantee safety lock only reaches corresponding rotating speed, just can open centrifugal block for clutch use, trigger lock rope swing arm, locked steel wire rope.
Safety lock also includes lock rope pin and lock rope preloading spring.In Fig. 2 example, pressing lock rope pin, it can promote lock rope swing arm to rotate, and opens tripper so that safety lock lock rope.Lock rope preloading spring ensures that lock rope pin will not trigger lock rope swing arm in normal state, it is to avoid false-lock phenomenon occurs.
The above is only optimal way of the present utility model; it should be pointed out that, for those skilled in the art, on the premise of without departing from this utility model know-why; can also make some improvements and modifications, these improvements and modifications also should be regarded as protection domain of the present utility model.
