Description
Technical field
The utility model is related to lifting appliance field, specifically a kind of protection type electromagnetism lifting machine.
Background technology
Electromagnetism lifting machine has many characteristics, such as that easy to use, absorption is secured, is currently widely used in industrial production, especially
It is scrap iron and steel department of recovery and steelshop.But it due to the particularity of electromagnetism lifting machine, i.e., once being powered off during lifting, hangs
The article of fortune will be fallen, and operating personnel are caused with personal injury, thus national quality supervision and inspection inspection on 2 21st, 2008
What epidemic disease general bureau promulgated《Hoisting machinery safety and technical supervision regulation-bridge crane》Of 66th article of regulation electromagnetic lifter
Weight electromagnet should be powered by special circuit.
In the prior art, the terminal plate of electromagnet is directly exposed on movable pulley, due to wherein electromagnet Special electric
The voltage on road is often higher, and exposed terminal plate may damage operating personnel；In addition, the adsorption capacity of electromagnet
It cannot adjust, when the article of handling is smaller, adsorption capacity surplus causes waste of energy, when the article of handling is heavier, in absorption
The phenomenon that inadequate.
Invention content
To solve the problems, such as that electric leakage risk in the prior art and electromagnet adsorption capacity are difficult to adjust, this practicality is new
Type provides a kind of butted line plate and carries out barrier protection and can be to protection type electromagnetism lifting machine that electromagnet turn on angle is adjusted.
The concrete scheme of the utility model is：A kind of protection type electromagnetism lifting machine, has hoisting traveling crane, and hoisting traveling crane includes
Gate row frame and the electric block moved along gate row frame, electric block lower section is lifted with electromagnet by movable pulley, special
Sign is：For the movable pulley tool there are two the sub- pulley being arranged side by side, the lower half portion of every sub- pulley is set with protective jacket,
Terminal plate is installed, one end of plate is connect by power transmission cable with power supply in succession, terminal plate on the outside of one of protective jacket
The other end is connect also by power transmission cable with electromagnet, protective casing is further sleeved with outside the terminal plate, to prevent electromagnet from leading to
Electric shock risk occurs under electricity condition on terminal plate；It is also equipped with changing the regulating device of transmission current size on the terminal plate.
Be connected with shaft between two sub- pulleys in the utility model, be set with sleeve in shaft, the both ends of sleeve with it is every
Protective jacket connection on a sub- pulley；The sleeve bottom end is welded with suspension hook, and suspension hook is sling electromagnet by load-bearing chain.
The utility model sets plate protective casing in succession, operating personnel can be effectively prevent accidentally to touch connecting plate and electric shock thing occurs
Therefore while the device regulating device on connecting plate, so as to which the article for different weight adjusts and provides handling therewith and matches
Electromagnetic adsorption power, power consumption is greatly saved, has good application prospect.

Specific embodiment
In the present embodiment, a kind of protection type electromagnetism lifting machine, have hoisting traveling crane, hoisting traveling crane include gate row frame 1 with
And the electric block 2 moved along gate row frame 1,2 lower section of electric block are lifted with electromagnet 4 by steel wire rope 15 and movable pulley 3,
There are two the sub- pulley 5 that is arranged side by side, the lower half portion of every sub- pulley 5 to be set with protective jacket 6 for the tool of movable pulley 3, and wherein one
The outside of a protective jacket 6 is equipped with terminal plate 7, and one end of plate 7 is connect by power transmission cable 8 with power supply in succession, terminal plate 7 it is another
One end is connect also by power transmission cable 8 with electromagnet 9, protective casing 10 is further sleeved with outside the terminal plate 7, to prevent electromagnet
Electric shock risk occurs under 9 energized states on terminal plate 7；It is also equipped with changing the adjusting of transmission current size on the terminal plate 7
Device 11.
In the present embodiment, shaft is connected between two sub- pulleys 5, sleeve 12, the both ends of sleeve 12 are set in shaft
It is connect with the protective jacket 6 on every sub- pulley 5,12 bottom end of sleeve is welded with suspension hook 13, and suspension hook 13 will by load-bearing chain 14
Electromagnet 4 is sling.
