Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of inhibiting device for dumping car, described device comprises proximity switch 1 and trigger unit thereof, proximity switch 1 one end is connected with the negative electricity of power supply, its other end is connected with pin under relay 4 side, under relay 4 opposite side, pin is electrically connected with one end of disengage button 5, the positive pole of the other end electric connection of power supply of disengage button 5; On relay 4 side, pin is electrically connected with one end of electromagnetic gas valve 3, the negative pole of the other end electric connection of power supply of electromagnetic gas valve 3, the positive pole of pin electric connection of power supply on relay 4 opposite side.
As shown in Figure 2, described with proximity switch 1 with the use of trigger unit be spacing iron plate 2, proximity switch 1 is direct current two wires NC type switch, it is fixed on the subframe at distance loading space front end face 500mm place, spacing iron plate 2 is flake structure, its specification is long 30mm × wide 30mm × thick 1mm, this spacing iron plate 2 be fixed on proximity switch 1 position directly over loading space bottom girder on, home state when proximity switch 1 and spacing iron plate 2 are fitted with the use of the lifting state for detecting loading space and loading space bottom girder and subframe.
As shown in Figure 3, described electromagnetic gas valve 3 is open in usual, electromagnetic gas valve 3 is connected in series in clutch power-assisted pump 34 gas circuit controlling device of motor brake operating 31 motion, the control loop of " solution-air booster type " clutch operation 31 comprises clutch operation 31, the power intake of clutch operation 31 is communicated with the clutch end of power-transfer clutch main pump 32, the power intake of power-transfer clutch main pump 32 is communicated with the clutch end of clutch power-assisted pump 34 by oil circuit 33, the power intake of clutch power-assisted pump 34 is communicated with the clutch end gas circuit of electromagnetic gas valve 3, the power intake of electromagnetic gas valve 3 is connected on air receiver 36.
Described spacing iron plate 2 is not more than 8mm with effective detecting distance of proximity switch 1.
Described disengage button 5 is closed type, and it is arranged on bridge instrumentation and faces left side position, is convenient to the operation that chaufeur realizes short-distance movement vehicle.
Principle of work of the present utility model and specific works process:
Proximity switch 1 is arranged on the subframe of dumping car, more spacing iron plate 2 is welded on container bottom girder; Be arranged on by electromagnetic gas valve 3 in booster pump of car clutch 34 gas circuit 35, disengage button 5 is arranged on bridge instrumentation and faces left side, and relay 4 is arranged in operator's compartment connection box.
When dumping car parking needs lifting to unload, it is that loading space leaves and subframe bonding position that loading space rises gradually, spacing iron plate 2 together rises with loading space, make proximity switch 1 be in on-state, and be energized to electromagnetic gas valve 3 by relay 4, close the source of the gas pipeline of clutch power-assisted pump 34, now, chaufeur cannot operate the clutch again and make it be separated, and then cannot hang up change speed gear box traveling gears, cannot realize driving.
When loading space starts to fall after rise, when spacing iron plate 2 is apart from proximity switch 1 detection faces 8mm, proximity switch 1 can detect signal, cut off; And give electromagnetic gas valve 3 power-off by relay 4, open the source of the gas pipeline of clutch power-assisted pump 34, now chaufeur ability normal operational power-transfer clutch and gearbox-gear, realize safe driving.
Under needing temporary transient short-distance movement vehicle or using power-transfer clutch to carry out throwing off the operational circumstances of change speed gear box power takeoff, dumping car is still in lifting state, chaufeur needs to continue to press disengage button 5 with left hand, this disengage button 5 can realize temporary transient operating the clutch, and realizes short-distance movement vehicle or throws off change speed gear box power takeoff; But before completing temporarily operation, the left hand that chaufeur presses disengage button 5 is limited, can not leave, remind chaufeur loading space to be in lifting state, after end of operation with the moment, chaufeur unclamps disengage button 5, and when loading space is still in lifting state, driving is still restricted.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
