The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
The utility model comprises combination fixed case 1 as depicted in figs. 1 and 2, combination fixed case 1 be one by the top 9 of sealing be placed in respectively the Semi surrounding type triangle casing that three side sealing that two side panels 12 of both sides form closes, Open Side Down for the triangle hypotenuse of combination fixed case 1, one straight flange is parallel with guide rail 7, combination fixed case 1 is fixedly mounted on guide bracket 8, guide bracket 8 is fixedly mounted on building, guide rail 7 is connected by pulley with guide bracket 8, guide rail 7 can slide up and down with respect to guide bracket 8 by pulley, on guide rail 7, be equidistantly installed with cross bar 6, cross bar 6 is vertical with guide rail 7, combination fixed case 1 is installed with spring steady pin 14 away from a jiao of guide rail 7, combination fixed case 1 box house is provided with backboard 13, backboard 13 is divided into two parts by combination fixed case 1 inner space, wherein a part is provided with back-moving spring 5, brake shoes fixed bin 11 and balancing point 3 are installed in another part space, brake shoes fixed bin 11 and two side panels 12 are fixedly welded into an integral body, balancing point 3 is arranged on brake shoes fixed bin 11 lower ends and is fixed on two side panels 12 by balancing point steady pin 4, balancing point 3 can rotate around balancing point steady pin 4, brake shoes 2 is installed on brake shoes fixed bin 11, brake shoes 2 can be in the interior movement of brake shoes fixed bin 11, back-moving spring 5 one end linking springs steady pins 14, the other end connects one end of brake shoes 2 by the opening on backboard 13, a brake shoes 2 other ends foremost part are downward inclined-plane, can when non-hurtling down, do not had the brake shoes 2 of regaining in time to block by anti-anti-slip track, brake shoes 2 near back-moving spring 5 part be provided with groove 10, groove 10 is opening down, thereby balancing point 3 can put in promotion brake shoes 2 in groove 10 and reach between the cross bar 6 in guide rail 7 in box body when rotating counterclockwise.
Combination fixed case 1 is for being installed together a plurality of component combinations of device, reaches the effect of automatic, self-locking, braking.Combination fixed case 1 is comprised of two side panels 12 and brake shoes fixed bin 11 etc., has balancing point fixed pin holes on side panel 12, and side panel 12 is welded into integral body with brake shoes fixed bin 11, as fixing brake shoes 2 with support the effect of brake shoes 2 when anti-fall;
Brake shoes 2 is made by an integral plate, and front end becomes an inclined-plane, and when guide rail 7 upwards moves, brake shoes 2 is positioned at brake shoes fixed bin 11, to rising, does not have any impact; One groove 10 is arranged at the interior bottom of brake shoes 2, and while rotating for balancing point 3, short balancing point rotates and outwards moves at the interior promotion brake shoes 2 of groove 10;
The back-moving spring 5 of brake shoes 2 is located at brake shoes 2 rear ends, one end is connected with spring steady pin 14, one end is connected with brake shoes 2, after brake shoes 2 is released by balancing point 3, for guaranteeing that brake shoes 2 does not cause the obstruction to equipment operation, rely on back-moving spring 5 that brake shoes 2 is retracted rapidly to reset under normal circumstances.
With the rotation balancing point 3 of self-weight reset function be one by growing, short two are fixedly connected into whole balancing point composition, and long balancing point 301 deadweights are greater than short balancing point 302, original state, rely on Action of Gravity Field, long balancing point 301 under, short balancing point 302 stretches in groove 10 and rides against groove 10 edges upper, when guide rail 7 moves upward, cross bar 6 can upwards hold up the long balancing point 301 stretching between cross bar 6, when cross bar 6 moves long balancing point 301 top, long balancing point 301 can restPose along with Action of Gravity Field falls to clockwise rotating, until next cross bar 6 holds up back and forth, like this, when guide rail 7 moves upward, brake shoes can not play any impact.
When guide rail 7 normal slowly operation downwards, because the front end of long balancing point 301 is in guide rail Inter cross bar, the cross bar 6 that guide rail is 7 presses down the slowly motion clockwise downwards of long balancing point 301, now short balancing point 302 can be in company with upwards rotating clockwise, when turning in groove 10, short balancing point 302 drive brake shoes 2 outwards slowly mobile, make brake shoes 2 front ends slowly stretch out combination fixed case 1 and stretch between cross bar 6, the back-moving spring 5 of brake shoes 2 rear ends is in the state of being stretched simultaneously, when cross bar 6 is separated with long balancing point 301 after bottom through long balancing point 301, because brake shoes 2 has lost the pressure that short balancing point 302 passes over, back-moving spring 5 resets automatic instantaneous, drive brake shoes 2 to reset simultaneously, long balancing point 301 restPoses under Action of Gravity Field, cause long balancing point 301 again between cross bar 6, simultaneously, because guide rail 7 declines operation slowly, although brake shoes 2 front ends stretch between cross bar 6, but because decrease speed is slow under normal circumstances, back-moving spring 5 resume speeds can make 2 front end holdup times of brake shoes of stretching into long soon and not, do not form obstacle, can not blocked by cross bar 6, can retract in time, thereby guarantee downward normal operation.When next cross bar 6 runs to while contacting with long balancing point 301, repeat above-mentioned action, so circulation realizes normal slow decreasing motion; When there is tenesmus fast because of fault in guide rail 7, because the front end of long balancing point 301 is between cross bar 6, because decrease speed is too fast, now back-moving spring 5 also not do not come and completely retract and reset, front end holdup time between cross bar 6 of making long balancing point 301 is long and blocked by next cross bar 6, cross bar 6 is held on brake shoes 2, has now reached prevention guide rail 7 and continued to fall downwards.
Brake shoes 2 upper surfaces also can be through increasing friction treatment, as long as contact and produce frictional resistance with cross bar 6, stop brake shoes 2 to reset, brake shoes 2 forms and hinders equipment simultaneously, cross bar 6 is shelved on to brake shoes 2 tops, simultaneously also stoped track 7 equipment of scaffold etc. to continue to fall downwards, until the effect of fall arrest.
Reach and prevent the effect of falling; Realize the self-latching safety braking of operational outfit; In practical application, we can also arrange the balancing point driving self locking safety anti-drop device of a plurality of same specifications at same vertical position, reach the many places self-latching safety braking under the quick operation conditions of equipment simultaneously;
Anti-fall device action of the present invention is sensitive, reliability is high, the accuracy of manufacture and cost be compared with low, simple in structure and volume is little, effective balancing point driving self locking safety anti-drop device easy to operate and safe.When normal work slowly moves, this device can normally move, when occur anti-fall wait tenesmus situation timer to reach automatically to prevent fall, the effect of arrestment operation;
The above is only to preferred embodiment of the present utility model, not the utility model is done to any pro forma restriction, every foundation technical spirit of the present utility model is to any simple modification made for any of the above embodiments, equivalent variations and modification, all belong in the scope of technical solutions of the utility model.
