Hole, one end of connecting shaft 2 is plugged in fixing hole, and flange thereon is fitted with fixed pan 6, then by flange and fixed pan
6 are welded and fixed, and its other end is plugged in the hinge hole of brake lever 13, realize being hinged for outer lead member 7 and brake lever 13.
Direct current generator 20 is connected with the left brake arm 21 of foot-operated frequency conversion brake and for detecting 20 turns of direct current generator
The motor rotations measurement inductive switch of moving-coil number（Not shown in figure）, proximity switch is fixed with by screw 3 on outer lead member 7 and is installed
Plate 4, is provided with proximity switch 5 on proximity switch installing plate 4, proximity switch 5 is used cooperatively with motor rotations measurement inductive switch,
The automatic detection and adjustment of foot-operated frequency conversion brake can be realized, it is ensured that braking effect.
The operation principle of flexible torque loading device is：During work, the piston rod 16 of pusher 17 is boosted upwards, piston rod
16 are applied on interior guiding element 1 and interior guiding element 1 is moved up relative to outer lead member 7, so that compression helical spring 12, helical spring 12
A upward thrust is produced to outer lead member 7 after deformation, promotes outer lead member 7 to act upwards, so that drive brake lever 13 to act,
Finally act left brake arm 21 and right brake arm 19, braking tile fragment 22 is embraced braked wheel, realize band-type brake.
After braking tile fragment 22 embraces braked wheel, brake lever 13 and outer lead member 7 are no longer moved, and pusher 17 continues work
Make, interior guiding element 1 continues compression helical spring 12, and helical spring 12 gradually increases the thrust of outer lead member 7, so as to reach brake force
The ever-increasing purpose of square.Finally when braking moment reaches requirement, i.e., when the load that pusher 17 is loaded reaches required value,
Locking nut 8 has a certain distance apart from the top surface of outer lead member 7, according to different foot-operated frequency conversion brakes and braking moment
It is required that, the distance is general in 2mm or so.The distance gives a clear and definite loading standard, operator is intuitively anticipated
Know whether institute's loading moment has reached requirement, so that stop loading in time, it is easy to control, it is not necessary to which that operator possesses very
Level of skill high, reduces operation difficulty.
The flexible torque loading device is by the resilient snubber that is set on interior guiding element so that the loaded load of pusher
Buffering is first passed around, is then just applied on brake lever, realize the flexible loading of torque, it is to avoid rigid shock, effectively
The performance and service life of equipment are ensure that, it is safe.
In the other embodiment of foot-operated frequency conversion brake：Proximity switch can also be not provided with outer lead member；Interior guiding element
Bottom can also be not provided with screwed hole, such as can be arranged to conventional pin-and-hole, and pin-and-hole, Liang Zhetong also now are provided with piston rod
Cross bearing pin and realize connection；External screw thread can be not provided with the extension of interior guiding element, now extension is only served for observing
Whether loading moment reaches the effect of requirement, is merely given as one and judges sign, and at this moment disconnecting prevention structure can be provided in outer leading
A stop section in the bottom endoporus of part, now the bottom of interior guiding element be arranged to multidiameter structure, the big footpath section of multi-diameter shaft with it is outer
Guiding element guiding is slidably matched, the shaft shoulder coordinates with the stop section block, you can prevent interior guiding element abjection outer lead member；Interior guiding element can be with
Without extension, now the top of outer lead member can be not provided with perforation, such as be closing at the top of outer lead member, now interior
The top of guiding element needs to be reserved with certain mobile space at the top of outer lead member；Interior guiding element can not be up-small and down-big ladder
Shaft-like, such as can also be an optical axis, and now a block disk can be welded on interior guiding element supplies resilient snubber to be formed
The top pressure face of top pressure；First attachment structure can also be arranged on outer lead member, and the second attachment structure is arranged on interior guiding element, now
180 degree is turned around equivalent to by the embodiment of Fig. 3, equally can also play the effect of flexible loading；Can also be not added with outer lead member
Work fixed pan；Fixing hole can also be not provided with outer lead member, now connecting shaft can directly be weldingly fixed on the outer of outer lead member
On side face；Connecting shaft can also can be such as set on brake lever without connecting shaft on outer lead member, equivalent to bearing pin, this
When outer lead member on open up pin-and-hole；Resilient snubber can also be disc spring or rubber sleeve.
The implementation of flexible torque loading device is for example shown in Fig. 1 ~ Fig. 3, the concrete structure of flexible torque loading device with it is upper
The flexible torque loading device stated described in foot-operated frequency conversion brake embodiment is identical, will not be described in detail herein.
