The specific embodiment
Need to prove, in the situation that do not conflict, embodiment and the feature in embodiment in the utility model can make up mutually.Describe below with reference to the accompanying drawings and in conjunction with the embodiments the utility model in detail.
As shown in Figure 1, concrete mixer comprises that two front leg struts 10,11, two rear support legs 12,13, four supporting legs 10,11,12,13 are installed in fixedly on capstan head.Two front leg struts 10,11 are telescopic leg, and two rear support legs 12,13 and fixedly capstan head is hinged are at the driving lower swing of hydraulic jack.Four supporting legs 10,11,12,13 all are equipped with a supporting leg lock 2.When supporting leg lock 2 was in released state, supporting leg 10,11,12,13 could launch.When supporting leg 10,11,12,13 was regained, supporting leg lock 2 was in lockup state, prevented supporting leg 10,11,12,13 actions.
As shown in Figures 2 and 3, supporting leg lock 2 comprises: housing 20, iron core 21, dead bolt 22, the first electromagnetic coil 25, the second electromagnetic coil 26, back-moving spring 23, operating grip 24, lock chamber 27.Housing 20 is arranged on the chassis of concrete mixer, locks chamber 27 and is arranged on supporting leg 12,13.Also housing 20 can be arranged on supporting leg 12,13 simultaneously, lock chamber 27 and be arranged on the chassis of concrete mixer.Dead bolt 22 is positioned at housing 20, and iron core 21 is fixed in housing 20, and iron core 21 is set with back-moving spring 23, is used for dead bolt 22 is resetted.Operating grip 24 is installed on dead bolt 22.
The first electromagnetic coil 25 is installed on iron core 21; The second electromagnetic coil 26 is installed on dead bolt 22.As described in Figure 4, the first electromagnetic coil 25 is identical with the second electromagnetic coil 26 direction of windings, the first electromagnetic coil 25 and the second electromagnetic coil 26 series connection, and gauge tap KA1 is relay switch, gauge tap KA1 is controlled by controller.
When controller obtain supporting leg 10,11,12,13 one of them when needing deployment signal, controller sends closure signal to the relay switch KA1 of this supporting leg lock 2, continuing, it is closed to close electric switch KA1.The first electromagnetic coil 25 and the second electromagnetic coil 26 get electric, and because the first electromagnetic coil 25 is identical with the second electromagnetic coil 26 direction of windings, iron core 21 is inhaled mutually with dead bolt 22, and dead bolt 22 heads are retracted in housing 20, and supporting leg lock 2 is in released state; Launch when controller obtains supporting leg 10,11,12,13, and when leaving supporting leg lock 2 position, controller sends opening signal to relay switch KA1, continue and close electric switch KA1 and open.The first electromagnetic coil 25 and the second electromagnetic coil 26 dead electricity, dead bolt 22 automatically resets under the effect of back-moving spring 23, and dead bolt 22 heads extend out to outside housing 20, and the supporting leg lock is in lockup state.When supporting leg 10,11,12,13 needs to regain, because dead bolt 22 heads are provided with an inclined-plane, under the ramp effect power of supporting leg to dead bolt 22 heads, back-moving spring 23 compressions, dead bolt 22 heads are regained, supporting leg lock automatic unlocking.After supporting leg was regained and put in place, dead bolt 22 heads automatically reset to locking in chamber 27 under the effect of back-moving spring 23, and the supporting leg lock is in lockup state.When the situation of the first electromagnetic coil 25 and the second electromagnetic coil 26 dead electricity, also can carry out release and locking by operating grip 24.
According to actual needs, also can control simultaneously or control separately four supporting legs 10,11,12,13.When four supporting legs 10,11,12,13 needed to launch, the gauge tap with four supporting leg locks 2 was closed simultaneously, and supporting leg lock 2 is in released state.In order to save cost, also can not adopt controller automatically to control, when four supporting legs 10,11,12,13 of concrete mixer needed to launch, the operator pressed gauge tap KA1, and the gauge tap of four supporting leg locks 2 is closed, and supporting leg lock 2 is in released state.
Supporting leg lock 2 also can only adopt an electromagnetic coil, when electromagnetic coil get electric after, iron core 21 is inhaled mutually with dead bolt 22.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
