Description
Technical field
The present invention relates to brake technical field, more particularly to a kind of board-like brake.
Background technology
Brake is one of most important safety component of elevator.Conventional brake type has drum brake, dish at present
Formula brake, disk brake and board-like brake.Wherein, board-like brake relies on the characteristics of its simple in construction and cost is low to exist
Elevator industry is used widely.Board-like brake is that the brake for realizing braking on the brake wheel is compressed by brake block.For
The miniaturization of board-like brake, the design requirement of low noise, due to brake block movement travel very it is small (typically 0.3mm~
Between 0.5mm), therefore high is required to the guiding accuracy of brake block.If the guiding accuracy of brake block is not enough, easily occurs clamping stagnation
Cause brake failure, trigger security incident.But high guiding accuracy requirement means the guiding parts of board-like brake
High size positions precision is needed, processing and the assembly difficulty of board-like brake is so greatly increased.In addition, being oriented to
A certain degree of abrasion is had after parts long-term action, it is therefore desirable to regularly check and clear up, more renew if necessary
Guiding parts.When checking and clearing up traditional board-like brake, it is necessary to which board-like brake is integrally pulled down, operation is very
Difficulty, is safeguarded and inconvenient.
The content of the invention
Based on this, the invention reside in the defect for overcoming prior art, there is provided a kind of board-like brake, the size of its parts
Position accuracy demand is relatively low, and processing is simple, and assembling is easy, easy to maintenance.
A kind of board-like brake, including electromagnetic core, support block, tripping spring, brake block, armature and lead, it is described
Electromagnetic core is fixed in the support block, and the electromagnetic core is provided with magnet coil, one end of the tripping spring and institute

At holding position, easy installation and removal.Post is directed to using the second fastener to be fixed at position to be installed, easy installation and removal.
In one of the embodiments, sliding bearing is provided between the pilot hole and lead, can be efficiently reduced
Friction loss and surface abrasion, it is ensured that armature slides smooth.
In one of the embodiments, the brake block is provided with the arc groove for being used for being adapted to braked wheel.Brake block
Greatly increased with the contact area of braked wheel, good braking effect.
In one of the embodiments, the electromagnetic core is provided with microswitch, and the armature is provided with touching part, institute
State microswitch to be correspondingly arranged with the touching part, to detect the operating state of armature, there is provided braking information.
In one of the embodiments, the erecting bed includes the first erecting bed and the second erecting bed, and described first installs
Platform, the second erecting bed are symmetrically arranged at the both sides of armature, and the pilot hole includes first be arranged on the first erecting bed
Pilot hole and the second pilot hole being arranged on the second erecting bed, the lead include the first lead and the second lead,
First lead and the first pilot hole slidable connection, second lead and second pilot hole are slidably
Connection.It so, it is possible to improve the stationarity that armature is slided, it is ensured that braking effect.
In one of the embodiments, the tripping spring is at least two, and tripping spring array is set described at least two
Put so that evenly, braking ability is good for armature stress.
In one of the embodiments, the support block is at least two, supports block array to set described at least two, makes
Electromagnetic core it is fixed, stationarity is good.
