The brake is thus mounted and fixed to a mounting member, which may be a hoisting machine, and the attachment 2 may be a bolt. The electromagnet 1 is tightly attached to the traction machine through the connecting pieces 2, the armature 4 and the friction plate 5 are pressed between the electromagnet 1 and the traction machine, the friction plate 5 is tightly attached to the traction wheel, and the armature 4 and the electromagnet 1 are tightly abutted, so that the distance between the armature 4 and the electromagnet 1 is smaller than 0.05mm and a signal of a microswitch can be triggered.

The stopper still includes a plurality of gasket 3, and 3 voltage-sharing of a plurality of gasket locate between electro-magnet 1 and the installing component, all has draw-in groove 31 on a plurality of gasket 3, and draw-in groove 31 cover is located on connecting piece 2. After the electromagnet 1 is tightly installed on the installation part, a plurality of gaskets 3 are inserted between the electromagnet 1 and the installation part, so that the distance between the electromagnet 1 and the installation part is adjusted, correspondingly, the distance between the electromagnet 1 and the armature 4 is also adjusted, the distance between the electromagnet 1 and the armature 4 is 0.35-0.45mm, and the requirements of an attraction state and a braking state are met. Insert a plurality of gasket 3 between electro-magnet 1 and installing component, come the interval of direct adjustment electro-magnet 1 and installing component through gasket 3, need not to twist and move connecting piece 2 and adjust the clearance, it is very convenient to adjust the operation, low in labor strength, efficient. Meanwhile, whether the distance between the electromagnet 1 and the armature 4 meets the specified requirement is measured through a measuring tool after the plurality of gaskets 3 are inserted, when the distance does not meet the specified requirement, the distance between the electromagnet 1 and the armature 4 can meet the specified requirement by increasing or reducing the number of the gaskets 3 through the measured difference, the distance can be adjusted in place through one-time measurement, frequent measurement in the adjusting process is not needed, and the installation efficiency of the brake is greatly improved.

In this embodiment, the number of the connecting members 2 is four, and the four connecting members 2 are respectively connected to four corners of the electromagnet 1. All the cover is equipped with a plurality of gasket 3 on every connecting piece 2, and the thickness of gasket 3 is 0.1 mm. The tolerance range of the distance adjustment between the electromagnet 1 and the armature 4 is within 0.1mm, the thickness of the gasket 3 is 0.1mm, the distance between the electromagnet 1 and the armature 4 is adjusted through the adjustment of the number of the gaskets 3 on the connecting piece 2, and the adjustment is very convenient.
