Description

A kind of electromagnetic locking structure for column type job platform
Technical field
This utility model relates to aerial work platform technical field, a kind of electromagnetic locking structure for column type job platform.
Background technology
Column type job platform is a kind of aerial work platform, support job platform synchronization lifting particular by lower mast, can be divided mainly into single column type overhead operation platform, double-mast formula aerial work platform, many column type overhead operation platforms, fixing column type overhead operation platform.But all there is a common problem in column type job platform at present the most on the market, it is simply that the column type job platform big stability of beat amount is bad, directly result in column type job platform rare blow out platform type or size of blowing out little.The lifting of column type job platform relies primarily on raising of hydraulic jack, drives pulling of each chain to lift.The mast mechanism of the most each group of mast group only relies on and forms an entirety by the connection of chain.Owing to chain has certain elasticity and only pulling force does not push up power, therefore when by the effect of external force or centre-of gravity shift, it is easy to the phenomenon fluctuated between mast group occurs.When floating power exceedes deadweight, it is more likely that cause column type job platform overturning that serious accident occurs.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provides a kind of electromagnetic locking structure for column type job platform.
This utility model solves its technical problem and be the technical scheme is that
A kind of electromagnetic locking structure for column type job platform, including fixing the electromagnetic lock weighing apparatus iron block being connected with upper mast, the right side of described electromagnetic lock weighing apparatus iron block is provided with electromagnetic lock main body, the left side of wherein said electromagnetic lock main body is provided with the electric magnet towards electromagnetic lock weighing apparatus iron block, described electromagnetic lock weighs iron block and has the most corresponding sawtooth on electric magnet, and described electromagnetic lock main body is provided with the spring for controlling electric magnet telescopic movable.
As a preference, the right side of described electromagnetic lock main body has movable cavity, and described spring is positioned at movable cavity, and described movable cavity is provided with can the portable plate of pressing spring, the middle of described portable plate is provided with connection post, and described connection post is connected through electromagnetic lock main body with electric magnet.
As a preference, described electromagnetic lock main body having pilot hole, be provided with guide finger in described pilot hole, the end of described guide finger is connected with electric magnet.
As a preference, the angle, θ of described sawtooth is 80 °~90 °.
The beneficial effects of the utility model are: this structure is according to the work characteristics of column type job platform, by rational structural improvement, especially by electromagnet design, energising locking, dead electricity unlock, the electric magnet dead electricity when needs are locked, relies on the elastic force of spring that electric magnet is pushed to weighing apparatus ferrum flank engagement and reaches locking effect.When electromagnetic lock is loosened in needs decline, electromagnetic mechanism module is energized, electric magnet overcomes elastic force to contact with electromagnetic lock firm banking, make the flank of tooth produce gap and unlock electromagnetic lock, mast mechanism is thus made to become a rigidity entirety, the effect that suppression mast group fluctuates can be played, efficiently solve the phenomenon that fluctuates that only chain there will be when connecting so that column type job platform stability is greatly improved.
