Problems solved by technology

[0002] As a hoisting tool, the magnetic lifter is used frequently and requires manual control of the handle. Sometimes when hoisting large plate workpieces, the body needs to lean forward to move the handle, which is difficult to operate, easy to touch the workpiece, and the workpiece may fall and be smashed. Therefore, a switch activation device is generally installed at the switch of the magnetic lifter. Since the switch of some magnetic lifters is located in some special positions, such as near the bottom of the magnetic lifter, if you want to add a switch activation device at the switch , the bottom surface of the switch starting device cannot be lower than the bottom surface of the magnetic lifter. If it is lower, the magnetic lifter cannot fully contact the workpiece, resulting in no suction. Therefore, it is best to set the drive shaft and driven shaft in the switch starting device to non- Concentric, for the non-concentric case of the transmission shaft and the driven shaft, it is often connected by gears, pulleys, sprockets, etc., which has defects such as complex structure, high cost, and high machining accuracy. For this reason, we propose a magnetic lifter control device

Embodiment 1

[0031] refer to figure 1 , is an embodiment of the present invention, which provides a control device for a magnetic lifter, including a control mechanism 200 provided with an eccentric drive sleeve 201, the eccentric drive sleeve 201 can connect the driven shaft and the magnetic lifter The heavy switch can be connected, and the driving shaft is installed at a position parallel to the driven shaft and not rotating at the same center of rotation, which avoids that the switch starting device for concentrically transmitting power to the switch cannot be placed at some special positions, and can be used. The power transmitted through the eccentric drive shaft sleeve 201 makes the switch of the lifting mechanism 100 open to start working.

[0032] Concretely, the lifting mechanism 100 includes a crane outer casing 101 of a hollow structure, a lifting hook 102 arranged at the upper end of the crane outer casing 101, a crane suction cup 103 arranged at the bottom end of the crane out...

Embodiment 2

[0036] refer to Figure 1 to Figure 9 , is the second embodiment of the present invention, which is based on the previous embodiment.

[0037] Specifically, the magnetic attraction assembly 104 includes a fixed magnet N pole 104a arranged at one upper end of the crane outer casing 101 , and a fixed magnet S pole 104b arranged at the other upper end of the crane outer casing 101 .

[0038]Preferably, the magnetic attraction assembly 104 also includes a moving magnet shaft 104c, one side of the upper end of the moving magnet shaft 104c is provided with a moving magnet N pole 104d, and the other side of the upper end of the moving magnet shaft 104c is provided with a moving magnet S pole 104e; When the rotating shaft 104c started to rotate, if the moving magnet N pole 104d on the moving magnet rotating shaft 104c was on the same side as the fixed magnet N pole 104a at the upper end of the crane housing 101, and the moving magnet S pole 104e on the moving magnet rotating shaft 104...

Abstract

The invention discloses a control device of a magnetic jack. The device is characterized by comprising a hoisting mechanism; the hoisting mechanism comprises a crane outer shell with a hollow structure, a hoisting hook arranged at the upper end of the crane outer shell, a crane sucker arranged at the bottom end of the crane outer shell, and a magnetic component arranged in the crane outer shell; and a control mechanism is included and comprises an eccentric transmission shaft sleeve matched with the magnetic component, a rotating motor matched with the eccentric transmission shaft sleeve, and a fixing assembly for fixing the rotating motor on the outer shell of the crane. The eccentric transmission shaft sleeve is used for replacing devices such as gears, belt wheels and chain wheels, the structural complexity is simplified, and the manufacturing cost is low.
