Detailed description of the invention
Each preferred embodiment of the present utility model is described in detail below in conjunction with example.It will be understood by those skilled in the art that this embodiment is exemplary, it does not also mean that and forms any restriction to this utility model.
Fig. 1 is the schematic diagram of the brake unit according to this utility model first preferred embodiment.As shown in Figure 1, be included in an end 5a according to the brake unit 1 of this utility model first preferred embodiment to be pivotally mounted to brake bar 5 on the bottom of movable equipment (not shown) by pivot 3, to be arranged on movable equipment and to act on the Compress Spring 7 of the other end 5b of brake bar 5 and to be arranged on movable equipment and its removable iron core 9a is connected to the solenoid 9 of the other end 5b of brake bar 5.Movable equipment need to be maintained at correct position be not shifted time, solenoid 9 and power supply are disconnected with the electric current of the coil 9b of sever supply solenoid 9, the magnetic field dissipate of the coil 9b generation of solenoid 9, brake bar 5 rotates around pivot 3 downward () under the effect of Compress Spring 7 in figure clockwise, thus the supporting surface be located thereon with movable equipment or track 11 contact and produce frictional force, hinder the movement of movable equipment.When movable equipment needs to be shifted, solenoid 9 and power supply are connected and supplies electric current with the coil 9b to solenoid 9, the coil 9b of solenoid 9 produces magnetic field, the downward active force that the removable iron core 9a of solenoid 9 overcomes Compress Spring 7 under the action of a magnetic field with brake bar 5 the other end 5b around pivot 3 upwards () in figure counterclockwise rotate, thus the supporting surface making brake bar 5 and movable equipment be located thereon or track 11 disengage, such operator just can move movable equipment easily.
As shown in Figure 1, assuming that the Compress Spring 7 downward active force acted on brake bar 5 is F1, from pivot 3 to the distance of Compress Spring 7 be L1, the rotary motion resistance that brake bar 5 and supporting surface or track 11 contact position supporting surface or track 11 pairs of brake bars 5 produce is F2, distance from pivot 3 to brake bar 5 and supporting surface or track 11 contact position is L2, brake bar 5 is F3 with the pressure of supporting surface or track 11 contact position brake bar 5 pairs of supporting surfaces or track 11, and the upwards suction of magnetic field to removable iron core 9a that solenoid 9 produces is F4.Prevent the size of the frictional force of movable equipment movement from being determined by the pressure F3 of brake bar 5 pairs of supporting surfaces or track 11, and according to active force and counteracting force principle, F3=F2, therefore, it is desirable to make the resistance F2 of supporting surface or the rotary motion of track 11 pairs of brake bars 5 large as far as possible.According to lever principle, F1 × L1=F2 × L2, in order to produce larger power F2 with less power F1, L1 should be greater than L2.Therefore, brake bar 5 should be designed to position 5c that brake bar 5 contacts with supporting surface or track 11 between pivot 3 and Compress Spring 7.The position 5c that brake bar 5 contacts with supporting surface or track 11 can be the protuberance from brake bar 5 to downward-extension.In shown preferred embodiment, the position 5c that brake bar 5 contacts with supporting surface or track 11 is designed to arcuate projection.In order to make braking more balance, happy and be convenient to safeguard, the position 5c that can contact with supporting surface or track 11 at brake bar 5 installs removable brake pad additional.When brake off, the upwards suction F4 of the magnetic field only needing solenoid 9 to produce to removable iron core 9a is equal to or greater than Compress Spring 7 and acts on downward directed force F 1 on brake bar 5.Due to can larger power F2 be produced, then produces larger frictional force with less power F1 according to this utility model, thus only need to supply to solenoid 9 the upwards suction F4 that relatively little electric current just can overcome power F1.
In the brake unit of this utility model first preferred embodiment, Compress Spring 7 is always tending towards applying downward directed force F 1 to the other end 5b of brake bar 5, it should be understood that and adopts other actuating device of such as cylinder or hydraulic cylinder to be also feasible.
