Abstract
The utility model discloses an electromagnetic power lost brake with an electric weather cock. The electromagnetic power lost brake comprises a casing and a main shaft, wherein a fan blade is installed at one end of the main shaft, which extends into the casing; brake disks are installed on two sides of the fan blade; a friction disk matched with one brake disk is fixed on one side of the brake disk; a magnetic yoke is fixed on the inner wall of the casing on one side of each friction disk; a coil I is arranged in a magnetic yoke groove; a raised end of each friction disk is fixed on a screw rod; the extending out section of the screw rod is arranged in an electric weather cock casing; a spring I is sheathed on the outer wall; a release lever is installed at the tail end of the spring I; a handle extending out of the electric weather cock casing is connected with the upper end of the release lever; an electromagnet is installed above the spring I and on the inner wall of the casing; a coil II is sheathed outside the electromagnet; an armature is arranged above the coil II; and a push handle opposite to the armature is arranged on the outer wall of the electric weather cock casing. The brake at the top of a head mast is under remote control to enables a motor to be under the release state, and has a manual release function, is convenient to operate, and is safe and reliable.
Description
Technical field:
The utility model relates to the break field, relates in particular to a kind of electromagnetism power-off brake of charged weathercock.
Background technique:
The motor of the electromagnetism power-off brake of this charged weathercock is mainly used on the tower machine swirl gear.The tower captain phase needs motor is in releasing state when not working, and is adjusted to downwind thereby the tower wall energy is freely rotated with the wind, makes tower wall wind-exposuring area minimum, makes the frontal resistance minimum of tower wall, avoids body of the tower to be fallen by wind.And this motor is installed in the tower crane top, as the manual unlocking break, makes motor be in releasing state, need climb up the top operational of tower crane, and is very inconvenient.The electronic release function of this scheme has solved this difficult problem effectively, can control on remote ground, and is convenient and practical.
The model utility content:
The purpose of this utility model provides a kind of electromagnetism power-off brake of charged weathercock, effectively solved need manually climb up the tower crane top carry out the manual unlocking break, be the difficult problem that motor is in manual release state of operation inconvenience.
The technical solution of the utility model is as follows:
A kind of electromagnetism power-off brake of charged weathercock, comprise housing, main shaft, electric wind mark housing, described housing one side is equipped with electric wind mark housing, described main shaft stretches into shell ends flabellum is installed, the described flabellum outside is equipped with brake disc, described brake disc one side is fixed with the friction disk that matches with brake disc, be fixed with yoke on the inner walls of described friction disk one side, be provided with coil one in the described yoke groove, it is characterized in that: described friction disk protruding terminus is fixed on the screw rod, the described screw rod section of stretching out places in the electric wind mark housing, screw jacket is equipped with spring one, described screw rod end is equipped with releasing rod, described releasing rod upper end is connected with the handle that stretches out electric wind mark housing, the top of described spring one, electromagnet is installed in the housing, and described electromagnet is set with coil two outward, the top of described coil two is provided with armature, and described electric wind mark housing outer wall is provided with the push away handle relative with armature.
The electromagnetism power-off brake of described charged weathercock is characterized in that: flip sleeve is equipped with sliding sleeve between described screw rod and the yoke, is set with spring two between described sliding sleeve and the screw rod, and an end of described spring two contacts with friction disk.
The utility model has the advantages that:
The utility model adopts the break at telecontrol tower crane top, makes motor be in releasing state, has the manual release function simultaneously, and is easy to operate, safe and reliable.
Description of drawings:
Fig. 1 is a structural representation of the present utility model.
Embodiment:
A kind of electromagnetism power-off brake of charged weathercock, comprise housing 1, main shaft 2, electric wind mark housing 3, housing 1 one sides are equipped with electric wind mark housing 3, main shaft 2 stretches into shell ends flabellum 4 is installed, flabellum 4 outsides are equipped with brake disc 5, brake disc 5 one sides are fixed with the friction disk 6 that matches with brake disc, be fixed with yoke 7 on the inner walls of friction disk 6 one sides, be provided with coil 1 in yoke 7 grooves, friction disk 6 protruding terminuss are fixed on the screw rod 9, screw rod 9 sections of stretching out place in the electric wind mark housing 3, be set with spring 1 on the screw rod outer wall, spring one 10 ends are equipped with releasing rod 11, releasing rod 11 upper ends are connected with the handle 12 that stretches out electric wind mark housing, the top of spring 1, electromagnet 13 is installed on the inwall of housing 1, is set with coil 2 14 on electromagnet 13 outer walls, the top of coil 2 14 is provided with armature 15, and electric wind mark housing 3 outer walls are provided with relative with the armature handle 16 that pushes away; Flip sleeve is equipped with sliding sleeve 17 between screw rod 9 and the yoke 7, is set with spring 2 18 between sliding sleeve 17 and the screw rod 9, and an end of spring 2 18 contacts with friction disk 6.
Electronic release working principle is as follows: after the coil 1 of electromagnetism power-off brake feeds the direct current of regulation earlier, when electric wind target coil 2 18 feeds direct current again, armature 15 adhesives, direct current in the coil 1 of Duan Kaiing again, this moment, armature 15 propped up releasing rod 11, made the friction disk 6 that links to each other with releasing rod 11 by screw rod 9 not make brake disc 5 be in releasing state to the motion of brake disc 5 directions, should in time disconnect the direct current of coil 2 18 at last, reach electronic release function.(note: coil two can not be switched on for a long time, otherwise can be burnt out.）
The also subsidiary manual release function of this scheme, its operating procedure: earlier to moving handle 12, inwardly push away handle 16 again, make armature 15 prop up releasing rod,, unclamp at last and push away handle 16, reach the manual release function in release handle 12.
