Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment in the present invention is described in further detail.
As shown in figs 1 to 6, the Wedge-type towing machine band-type brake fender guard that the present invention relates to, include brake control lever 1, retarding spring 2, magnet coil 3, pull bar 4, shoe plate assembly 5 and traction sheave 6, described brake control lever 1 is arranged on the both sides of magnet coil 3, pull bar 4 is installed on two brake control levers 1, pull bar 4 two ends are provided with retarding spring 2, the inner of two retarding springs 2 is pressed on brake control lever 1, two brake control levers 1 in left and right are respectively arranged with shoe plate assembly 5, traction sheave 6 is arranged between two shoe plate assemblies 5, also include push rod, electromagnet 7 and voussoir 8, described voussoir 8 is four, in the middle part of the magnet coil 3 that symmetrical core shift is respectively hinged on both sides, front and back below platform on, described push rod is divided into left push rod 9 and right push rod 10 to be separately positioned on corresponding brake control lever 1, the external part of described left push rod 9 and right push rod 10 is positioned at below voussoir 8 corresponding separately, described electromagnet 7 is separately positioned on the platform 13 of below in the middle part of the magnet coil 3 corresponding to voussoir 8 movable end.
Described magnet coil 3 both sides are respectively arranged with rang sensor 11.
Platform 13 below in the middle part of the magnet coil 3 on the movable end side of described voussoir 8 is provided with position switch 12, and the control end of described position switch 12 matches with the gabarit of voussoir 8 movable end.
Under normal circumstances, voussoir 8 keeps horizontality respectively under the effect of lifting of corresponding left push rod 9 and right push rod 10 in the present invention; When brake off state, magnet coil 3 and electromagnet 7 switch on power, and electromagnet 7 holds voussoir 8, magnet coil 3 drives brake control lever 1, brake control lever 1 drives left push rod 9 and right push rod 10 to move to both sides, drives shoe plate assembly 5 to leave traction sheave 6, brake off state.
The present invention in motor power-off and retarding spring 2 failure fracture time, brake control lever 1 does not reset due to retarding spring 2 fault, rang sensor 11 senses that brake control lever 1 does not reset, and by signal transmission to the master board of elevator, and interrupt all run signal of elevator, magnet coil 3 and electromagnet 7 power-off, voussoir 8 is rotated down along S. A. under gravity, what now voussoir 8 was pressed by the rotation of traction wheel 6 is more and more tighter, until force traction wheel 6 stop motion, meanwhile, position switch 12 is touched, position switch 12 is connected on elevator emergency and stops in loop, lost efficacy to prevent rang sensor 11, when whole elevator has a power failure suddenly, magnet coil 3 and electromagnet 7 power-off, identical with preorder, also can reach same effect, when towing machine band-type brake recovers normally to work, namely when retarding spring 2 recovers normal, the voussoir 8 rotated can be push spinning reduction by left push rod 9 and right push rod 10, now the normal power on/off logic of elevator makes electromagnet 7 be energized, voussoir 8 is attracted on electromagnet 7, and keeps this state until next failure problems occurs.
When a failure occurs; traction wheel 6 is when different directions rotates; due to voussoir 8 above with the difference of voussoir 8 articulated position thus whichever direction are rotated and always had a voussoir 8 respectively on front and back under the rotation of traction wheel 6 below; more and more tighter; until stop motion, reach the effect of band-type brake protection.
When only having side retarding spring 2 to lose efficacy, four voussoirs 8 of both sides all fall with Action of Gravity Field, corresponding voussoir 8 holds up by the push rod of normal brake application spring 2 side respectively, voussoir 8 rotations along with traction wheel 6 of inefficacy side and stuck, until traction wheel 6 stop motion; When traction wheel 6 is with different hand of rotation, two voussoirs 8 being positioned at the two sides, front and back of side always have a voussoir 8 to rotate and stuck along with traction wheel 6, play the effect of braking.
The above, be only better possible embodiments of the present invention, and be not used to limit scope of the present invention.
