Description
Technical field
This utility model relates to switch element, a kind of Telescopic shaft type gang switch in cage type elevator brake unit.
Background technology
In order to detect whether the abrasion of the brake rubber block in cage type elevator brake unit has reached preset thickness, need to remain to when having a power failure be connected by gang switch special hindered circuit by the warning report of dry cell power supply, to send signal in time to safeguard, and though existing gang switch has a variety of, but it mostly is and is completed by machinery trigger electromagnet adhesive, this structure must make electric magnet be chronically at "on" position, therefore this structure is when having a power failure, it is impossible to normally works.
Utility model content
The purpose of this utility model is just to provide a kind of novel structure, reliable operation, easy for installation, the Telescopic shaft type gang switch of length in service life.
nullFor reaching above-mentioned purpose，This utility model includes expansion link、Compression spring、Shell、Positive stop、Nut、Locking nut、Rosette、Upper lead-in wire、Upper spring leaf、Lower lead-in wire、Lower spring sheet and several bolts，Described expansion link includes conehead and guide rod，And on the outer round surface on the top of described guide rod, it is provided with guide rod external screw thread，Described shell is sequentially provided with setting of casing from bottom to top、Boss and upper sleeve pipe，Described cased outer round surface is provided with setting of casing external screw thread，The middle part of the endoporus of described boss is provided with cannelure，It is provided with mounting hole on the right side tube wall of sleeve pipe on described，The conehead of described expansion link is threaded onto in the hole of shell down，Described compression spring is set on guide rod and is loaded between conehead and shell，Described nut and locking nut are loaded on guide rod the most from bottom to up by thread connection，The horizontal plate of described positive stop inserts in the mounting hole of upper sleeve pipe，And the vertical edges of described positive stop is loaded on the right outside sidewall of upper sleeve pipe by bolt，Described upper lead-in wire and upper spring leaf are loaded on left outside sidewall and the left inside sidewall of sleeve pipe upper position respectively by bolt，Described lower lead-in wire and lower spring sheet are loaded on left outside sidewall and the left inside sidewall of sleeve pipe upper position respectively by bolt，And described upper spring leaf and lower spring sheet are symmetrically arranged on the left inside sidewall of sleeve pipe，Described rosette is loaded on the left outside sidewall of upper sleeve pipe by bolt.
This utility model is because have employed the structure being made up of expansion link, compression spring, shell, positive stop, nut, locking nut, rosette, upper lead-in wire, upper spring leaf, lower lead-in wire, lower spring sheet and several bolts, so, when the brake rubber block in cage type elevator brake unit may wear to preset value, under the elastic force effect of compression spring, expansion link moves down, then, by nut, upper spring leaf is fitted with lower spring sheet and connect warning report barrier circuit；It addition, be located at the cannelure in the middle part of the endoporus of boss, it is simple to fill grease, in order to expansion link can upper and lower easy slide.This utility model novel structure, reliable operation, easy for installation, service life is long.
