Description
Technical field
The invention belongs to full section hard rock mole technical field of engineering machinery, be primarily aimed at the braking of hard rock mole main drive motor.
Background technique
Full section hard rock mole mainly relies on the disk cutter on the motor driving cutterhead that the rock that excavates face is carried out the roll extrusion fragmentation.Motor power supports through speed reducer, gear pair and revolution and is delivered to cutterhead.In the hard rock mole work progress and when changing disk cutter, cutterhead needs frequent start and stop, in order to protect maintenance personnel's safety, must effectively brake by the tool setting disk-drive motor.Traditional mode of braking makes the enough frictional force of generation between them for to compress the sound brake block through hydraulic pressure installation, and then realizes the purpose of braking.Because braking device is installed between motor and the speed reducer, therefore have the maintaining difficulty, period of braking is long and produces too much heat during because of braking to cause shortcomings such as speed reducer oil ageing quickening.So develop a kind of simple in structure, braking hard rock mole main drive motor break reliable, easy to maintenance, long service life and be and be badly in need of both at home and abroad the new problem that solves.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structurely, braking is reliable, and is easy to maintenance, the hard rock mole main drive motor break of long service life.
The objective of the invention is to realize like this: a kind of hard rock mole main drive motor break, whole device is made up of bolt, braking hub, brake cylinder, clamping strap, adjusting bolt, rocker lever, support and spring, and the braking hub is through being bolted to main drive motor axle afterbody; Clamping strap is installed in the braking hub outside, and leaves certain interval, and support is fixed by bolts on the motor housing; Clamping strap one end is bolted on the support through adjusting; The other end is connected with rocker lever, and rocker lever is rack-mount, and brake cylinder is fixed on support top; The pull bar on the brake cylinder and the other end of rocker lever are hinged; Support is through being bolted on the motor housing, and spring one end links to each other with support, and the other end is connected with rocker lever; The working principle of said device is that the pull bar of brake cylinder stretches out during braking, drives rocker lever and rotates, and then strain clamping strap, makes between clamping strap and the braking hub and produces enough frictional force, realize the purpose of braking, and in braking process, spring is elongated; When stopping to brake, spring pulling rocker lever drives clamping strap and resets, and after use a period of time, after clamping strap may wear to a certain degree, through regulating the gap between bolt adjustment clamping strap and the braking hub, guarantees the reliability of braking; The installation method of said hard rock mole break on motor be, will brake hub and be fixed by bolts to main drive motor axle afterbody, and clamping strap is placed on braking hub outside; Support is fixed by bolts on the motor housing, and rocker lever is installed on the axle of support, and clamping strap one end is bolted on the support through adjusting; The other end is connected with rocker lever, and brake cylinder is fixed to support top, and the brake cylinder pull bar is connected with rocker lever; Spring one end is connected with support, and the other end is connected with rocker lever, and the brake cylinder pull bar stretches out during braking; The drive rocker lever rotates, and then the purpose of tension clamping strap realization braking, when stopping to brake; Spring pulling rocker lever drives clamping strap and resets, after use a period of time, after clamping strap may wear to a certain degree; Through regulating the gap between bolt adjustment clamping strap and the braking hub, guarantee the reliability of braking.
Main points of the present invention are its structure and working principle.Its working principle is that the pull bar of brake cylinder stretches out during braking, drives rocker lever and rotates, and then strain clamping strap, makes between clamping strap and the braking hub and produces enough frictional force, realize the purpose of braking, and in braking process, spring is elongated; When stopping to brake, spring pulling rocker lever drives clamping strap and resets, and after use a period of time, after clamping strap may wear to a certain degree, through regulating the gap between bolt adjustment clamping strap and the braking hub, guarantees the reliability of braking.
Hard rock mole main drive motor break compared with prior art has simple in structurely, and braking is reliable, and easy to maintenance, advantages such as long service life will be widely used in the hard rock mole technical field of engineering machinery.
