Perforate connecting rod 911 is also socketed in board shaft 91, perforate connecting rod 911 passes through U-shaped board through hole 83, and the end of perforate connecting rod 911 is provided with regulation
Nut 9111, stage clip 9112 is cased with the perforate connecting rod 911 between adjusting nut 9111 and the base of U-shaped board 8；The U-shaped bottom of plate 9 of declutching
Striking plate 92 is fixedly connected with the outside of portion, the bottom of striking plate 92 is provided with hanging scroll 93, trigger mechanism is additionally provided between swing arm 10 and hanging scroll 93.
Trigger mechanism includes the rotary shaft 711 through the one end of yoke plate 71, and the both ends of rotary shaft 711 are respectively with hooking plate 11 and linkage
Plate 12 is fixedly connected, and torsion spring 13 is additionally provided between linkage board 12 and yoke plate 71；The inner side of swing arm 10 is also fixedly connected with pressing plate 103, presses
The end of plate 103 is located on the end of linkage board 12.
The end of linkage board 12 is provided with adjustment screw 121.U-shaped plate end 94 of declutching is set to arcuation.
The rear end of swing arm 10 is additionally provided with balance weight 102, by adjusting the weight of the balance weight 102 in swing arm 10, can reach
Adjust the purpose of braking response speed.
Three hole otic placodes 6 are two parallel three hole otic placodes 6, and two hole otic placodes 7 are two parallel two hole otic placodes 7, preceding braking
Arm 2 is two parallel preceding brake arms 2, and rear brake arm 3 is brake arm 3 after parallel two.
The U-shaped board shaft 91 that declutches extends to the top of swing arm 10, serves position-limiting action of the swing arm 10 when swinging.
Touching lever (being to draw in figure) is fixedly connected on the bottom of U-board 8, when braking generation, as the bottom of U-board 8 is inside
Movement, touching lever be used for impact stroke switch contact, realize hoist engine power off.
Specific embodiment is as follows：
The end face of the reel tail end 15 of braking, integral with the reel of window cleaning equipment required for plum blossom wheel 14 is fixedly mounted on,
Rotated with reel.
Prepsetting gap between preceding brake shoe 4 and rear brake shoe 5 can be adjusted by adjusting screw-casing 611, it is suitable to ensure
Brake force.
By adjusting adjusting nut 9111, stage clip 9112 can be made to keep appropriate elastic force under the state of declutching.
During normal work, because the declutch U-shaped plate end 94 of declutching of plate 9 of U-shaped is arcuation, and the roller 81 of U-board 8 is resisted against
On.
In order to prevent U-shaped plate end 94 of declutching from departing from roller 81 against hooking plate 11 and be hooked on hanging scroll 93, prevent
Only forward and backward brake shoe holds plum blossom wheel 14 tightly.
Because brake wheel 101 is connected to the end of swing arm 10, the bottom of 10 and two hole otic placode of swing arm 7 with rear brake arm 3
Top be hinged, swing arm 10 formed a cantilever design；It is outline of the migration in plum blossom wheel 14 during 101 normal work of brake wheel
On face, when the 1 times of rotation of the critical hypervelocity of reel, tooth top of the brake wheel 101 only with plum blossom wheel 14 is touched.
Adjusting screw 121 on linkage board 12 can be used for experiencing the significantly pendulum that swing arm 10 triggers by ultracentrifugation power
It is dynamic, so as to ignite trigger mechanism action, realize braking.By adjusting the adjusting screw 121 on linkage board 12 so that trigger mechanism
When reel exceeds the speed limit, hook plate 11 can be made to be separated from hanging scroll 93.
As shown in figure 4, after reel exceedes certain speed, swing arm 10 rotates clockwise, and pressing plate 103 thereon is also with swing arm
10 rotate clockwise, and the adjusting screw 121 of the end of pressing plate 103 pressing linkage board 12 end, rotate counterclockwise rotary shaft 711,
Drive hook plate 11 also to rotate counterclockwise simultaneously, the hook plate 11 originally together with the hooking of hanging scroll 93 is separated from hanging scroll 93.
The tension force under the state of declutching of stage clip 9112 is maximum, when brake occur when, i.e. U-shaped plate end 94 of declutching is de- with roller 81
From against the tension force of stage clip 9112 release, drive U-board 8 moves inward, that is, reducing the top of three hole otic placode 6 and two holes
The distance between top of otic placode 7, and preceding brake shoe 4 and rear brake shoe 5 is held plum blossom wheel 14 tightly.
When reel hypervelocity (downstream rate is more than 20m/min.) rotates, plum blossom takes turns braking of 14 crowns to the end of swing arm 10
When roller 101 produces a larger centrifugation impact cause swing arm pendulum 10 gyrations increase, pressing plate 103, which presses adjusting screw 121, to be made
Plate 11, which must be hooked, can unclamp linking to hanging scroll 93, and because U-shaped plate end 94 of declutching is set to arcuation, now the U-shaped plate 9 that declutches is easy to
It can rotate clockwise, while discharge the tension force of stage clip 9112, forward and backward brake shoe holds plum blossom wheel 14 tightly, reaches braking purpose.
After spool velocity is near certain value, hooks plate 11 and be separated from hanging scroll 93, under drum functions vibration, U-shaped declutches plate
The arch section of end 94 can cross dead-centre position and be rotated clockwise with the U-shaped board shaft 91 that declutches, and its U-shaped declutches the arc of plate end 94
Part with U-shaped declutch plate 9 rotate clockwise unclamp pair roller 81 against so as to reach braking purpose.
U-shaped plate end 94 and roller 81 part that leans of declutching is a bit of straight line, and the flex point of straight line and camber line is U-shaped
The dead-centre position when plate 9 that declutches rotates, because the U-shaped end arc dead-centre position of plate 9 that declutches is more sensitive, during normal operation, lead to
The instrument of mistake makes hook plate 11 catch on hanging scroll 93, with false action-proof.
Certainly, the utility model can also have other various embodiments, without departing substantially from the utility model spirit and its essence
In the case of, those skilled in the art work as can make various corresponding changes and deformation according to the utility model, but these
Corresponding change and deformation should all belong to the scope of the claims appended by the utility model.
