Embodiment
The utility model is the following technical schemes are provided: a kind of Rapid reset window cleaning equipment is filled with overspeed protection referring to FIG. 1-2,
It sets, including pawl base 4, the top of the pawl base 4 is provided with driving wheel 1, and the inner ring of the driving wheel 1 is threaded with
One end of spool shaft 9, the spool shaft 9 is fixedly connected with reel 13, and the left side of the driving wheel 1 passes through interior square hole and adjusting
Bolt 2 is connected with braked wheel 12, driving wheel 1 and braked wheel 12 by interior square hole or key connection transmitting braking moment, adjusts
Section bolt 2 is solely subjected to axial force and is not subject to the circumferential shear power that braking moment generates, and guarantees that it does not fail, fills overspeed protection
Energy reliably working is set, the left side of the braked wheel 12 is provided with cam adjustment circle 11, the outer surface of the cam adjustment circle 11
It is provided with triggering cam 3, the right side of the reel 13 and the opposite face of cam adjustment circle 11 are provided with buffer spring 10, pass through
10 pressing force of buffer spring generate moment of friction, prevent reel 13 under suspension platform gravity revolving speed increase it is too fast,
When 10 moment of friction of buffer spring is equal to 13 torque of reel with suspension platform gravity, reel 13 reduces speed now, due to reel
13 are still rotating, and driving wheel 1 and braked wheel 12 continue to move to compress buffer spring 10, and moment of friction continues to increase until reel 13
It stops operating, realizes that hoisting mechanism is gently braked, hard brake down is avoided to impact, the left side of the pawl base 4 is living by pin shaft
Dynamic to be connected with brake pawl 8, the front and back of the brake pawl 8, which is respectively arranged with, adjusts weight 6 and triggering idler wheel 7, institute
The right side for stating pawl base 4 is fixedly connected with limit switches 5, by setting triggering cam 3, adjusts weight 6, brake pawl 8
With driving wheel 1, the relative position of brake pawl 8 and driving wheel 1 is adjusted by adjusting triggering cam 3 and adjusting weight 6, so that
Suspension platform can be braked reliably in time when decline reaches triggering speed, guarantee suspension platform and operator's high altitude operation peace
Entirely.
Specifically, the pawl base 4 is fixedly connected on the top of elevator cabinet.
Specifically, the spool shaft 9 is provided with external screw thread and internal screw thread with driving wheel 1 in overspeed protective device construction section
It matches.
Specifically, compression degree is adjusted by buffer spring 10 and adjusting bolt 2 in the braked wheel 12, pass through adjusting
Bolt 2 adjusts the sideshake of braked wheel 12 and driving wheel 1, first discharges 10 pressing force of buffer spring when brake resets, has
Effect reduces the thread friction power of driving wheel 1 Yu spool shaft 9, and driving wheel 1 is made to be easy to reset.
Specifically, the right side of the braked wheel 12 and 1 left side of driving wheel maintain a certain distance.
The working principle and process for using of the utility model: when the utility model reel 13 works normally, driving wheel 1 and system
Driving wheel 12 is under the effect of 10 pressing force of buffer spring, as spool shaft 9 rotates synchronously, and triggering cam 3 is driven to rotate, triggered convex
3 interval of wheel hits the triggering idler wheel 7 of 8 tail portion of brake pawl, makes ratchet pawl of 8 front end of brake pawl on driving wheel 1, normally
Under working condition, by adjusting cam adjustment circle 11 and adjusting the position of weight 6, make 8 front end of brake pawl during the swing
Be staggered the ratchet pawl of driving wheel 1, and brake does not trigger, and when electromotor brake fails, reel 13 is under suspension platform gravity
Overspeed rotation and reach triggering speed when, 8 front end of brake pawl sticks into the ratchet pawl of driving wheel 1, and driving wheel 1 cannot be with reel
Axis 9 rotates, and under 9 external screw thread of spool shaft and the effect of 1 internal screw thread of driving wheel, driving wheel 1 is mobile toward 13 direction of reel, withstands braking
Wheel 12 continues to compress buffer spring 10, under the effect of 10 pressing force of spring, when its end face and 12 side moment of friction of braked wheel are super
When crossing torque of the suspension work platform gravity to reel 13, reel 13 gradually slows down until stopping, and suspension platform is braked；
After electromotor brake troubleshooting, overspeed protective device is resetted by following operation, loosens adjust first
Bolt 2 is saved, so that braked wheel 12 is turned right movement under the effect of buffer spring 10, the pressure of buffer spring 10 is discharged, to reduce
Friction braking torque after 12 right side of braked wheel is adjacent to 1 left side of driving wheel, rotates driving wheel 1, makes its movement of turning right, returns
Initial position is arrived again, and precession adjusts bolt 2, braked wheel 12 is compressed, by the gap adjustment of braked wheel 12 and driving wheel 1 to initial shape
State, brake reset finish.
