Remaining feature and concrete principle of work are same as the previously described embodiments in the present embodiment, repeat no more herein.
The utility model another embodiment also provide another Anti-hook releasing device, and as shown in Figure 2, between described Anti-hook releasing device connection and anode and negative pole, described Anti-hook releasing device comprises: sensor unit 101 and operating unit 102 in parallel; Wherein:
Sensor unit 101 comprises:
Anodal the first contact switch S1 and the second contact switch S2 being connected with described anode respectively, the negative pole of the first contact switch S1 and the second contact switch S2 is connected with the negative pole of described battery respectively;
Be connected in the positive pole of the first contact switch S1 and the first coil K1 between mouth;
The the second coil K2 being connected in parallel with the first coil K1;
The tertiary winding K3 that one end is connected with the mouth of the second contact switch S2;
Be connected in the 4th coil K4 between the tertiary winding K3 other end and described battery cathode;
The first switch Q1 that one end is connected with the point of connection of tertiary winding K3 and the 4th coil K4; The other end of the first switch Q1 is connected with described anode;
Preferably, operating unit 102 comprises:
The first electromagnetic valve Y1 that one end is connected with described battery cathode; The other end of the first electromagnetic valve Y1 is connected with described anode by the normally closed contact K11 of the first coil K1;
The second electromagnetic valve Y2 that one end is connected with described battery cathode;
The 3rd electromagnetic valve Y3 that one end is connected with described battery cathode; The other end of the second electromagnetic valve Y2, by the open contact K20 of the second coil K2 and the open contact K40 of the 4th coil K4 of series connection, connects the other end of the 3rd electromagnetic valve Y3;
The motor contactless switch KM that one end is connected with described battery cathode;
Often open the second switch Q2 that input end is connected with described anode; The normally closed mouth of second switch Q2 is connected with the point of connection of the open contact K40 of the 3rd electromagnetic valve Y3 and the 4th coil K4, the normally closed input end of second switch Q2 with often open mouth and be connected, both point of connection are connected with the other end of motor contactless switch KM;
The 4th electromagnetic valve Y4 that one end is connected with described battery cathode;
The 3rd switch Q3 that normally closed mouth is connected with the 4th electromagnetic valve Y4 other end; The normally closed input end of the 3rd switch Q3 with often open mouth and be connected, both point of connection are connected with the mouth of often opening of second switch Q2; The input end of often opening of the 3rd switch Q3 is connected with described anode by the open contact K30 of tertiary winding K3 and the normally closed contact K41 of the 4th coil K4 in parallel.
Concrete principle of work is:
When the first switch Q1 is closure state, described waste-skip is in unloading case mode of operation; The second contact switch S2 responds to the location information of described subframe, the probe of the second approach switch S2 just in time can be blocked in the normal position of described subframe, make the second approach switch S2 in running order, and then Shi Yi road electric current arrives described battery cathode through the first switch Q1, tertiary winding K3, the second approach switch S2, another road electric current arrives battery cathode by the first switch Q1 and the 4th coil K4, so tertiary winding K3 and the 4th coil K4 all electric, open contact K30 is closed, open contact K40 is closed, and normally closed contact K41 disconnects.
Operator presses the lifting button in described compartment, makes often opening input end and often opening mouth conducting of the 3rd switch Q3, and the normally closed input end of the 3rd switch Q3 and normally closed mouth disconnect; Electric current passes through normally closed often the opening input end and often opening mouth of contact K30 and the 3rd switch Q3 conducting of opening, and flows into motor contactless switch KM, and motor contactless switch KM controls described compartment and starts lifting action.
Lifting due to described compartment, the the first contact switch S1 that responds to described car position information starts working, make the first coil K1 and the second coil K2 obtain electric, normally closed contact K11 opens because the first coil K1 obtains the magnetic action after electric, and the first electromagnetic valve Y1 controls self-unloading lock oil cylinder and stops oil return; Open contact K20 is closure because the second coil K2 obtains magnetic action after electric, and making the second electromagnetic valve Y2 control described self-unloading, to lock oil cylinder fuel-displaced, makes described compartment depart from described subframe.
When described compartment can normally depart from described subframe, because described subframe is still in normal position, can block the probe of the second approach switch S2, therefore the second approach switch S2 is now in running order, tertiary winding K3 and the 4th coil K4 can also obtain electric, open contact K30 is closed, and open contact K40 is closed, and normally closed contact K41 disconnects; Electric current flows into motor contactless switch KM and the 3rd electromagnetic valve Y3 through open contact K30 and the 3rd switch Q3, and described compartment is unloaded.
When described compartment can not normally depart from described subframe, because described subframe is driven by described compartment, left the normal position of described subframe, can not block the probe of the second approach switch S2, the second approach switch S2 does not work, tertiary winding K3 dead electricity, and the 4th coil K4 can continue electricly by the first switch Q1, open contact K30 disconnects, and open contact K40 is still closed, normally closed contact K41 disconnects, therefore open contact K30 and normally closed contact K41 all disconnect, thereby cause the 3rd switch Q3 dead electricity, motor contactless switch KM dead electricity, described compartment stops lifting action, and because if operator presses the decline button in described compartment, second switch Q2 still can obtain electric, so now decline can also be realized in described compartment, but can not lifting, with this, remind operator's et out of order, and prevent from breaking off relations after described subframe from being taken away normal position by described compartment, the accident of described vehicle frame is got in tenesmus.
Remaining feature and concrete principle of work are same as the previously described embodiments in the present embodiment, repeat no more herein.
Preferably, as described in Figure 3, operating unit 102 also comprises: the warning buzzer phone G being connected in parallel with motor contactless switch KM.
Described waste-skip is in unloading case mode of operation, when motor contactless switch KM controls described compartment and carries out lifting action, warns buzzer phone G simultaneously and obtains electricly, sends sound, to remind personnel around away from described compartment; And when described compartment can not normally depart from described subframe, warn buzzer phone G dead electricity simultaneously, can not send sound, make operator in the fault that makes discovery from observation, can also stop sounding by warning buzzer phone G and find fault, on the basis of above-described embodiment, increase a sound prompting function.
Remaining feature and concrete principle of work are same as the previously described embodiments in the present embodiment, repeat no more herein.
Above-mentioned explanation to the disclosed embodiments, makes professional and technical personnel in the field can realize or use the utility model.To the multiple modification of these embodiment, will be apparent for those skilled in the art, General Principle as defined herein can, in the situation that not departing from spirit or scope of the present utility model, realize in other embodiments.Therefore, the utility model will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
