As shown in figure 8, further including safety valve 13；The oil outlet of hydraulic pump 62 is arranged in fuel tank 61 in the safety valve 13
On oily channel.
It further include filter 14；The filter 14 is arranged on fuel tank 61 to the oily channel of the oil inlet of hydraulic pump 62.
As shown in Figure 10, the present invention is in use, the cylinder body 63-1 of elevating ram 63 is hinged in the rack 80 of dumper,
The rack 80 of carriage body 50 and dumper is hinged, as shown in Figure 1 and Figure 4, mounting rack 15 is fixedly connected on compartment by fastener
On body 50.
Working principle of the present invention is as follows: when needing to lift the carriage body 50 of dumper, hand-operated direction valve 64 is operated, hand is made
The oil inlet P of dynamic reversal valve 64 is communicated with mouth A is executed, and the pressure oil in hydraulic pump 62 reaches elevating ram through hand-operated direction valve 64
The piston rod 63-2 of 63 rodless cavity, elevating ram 63 stretches out, meanwhile, the pressure oil in hydraulic pump 62 can also be through hand-operated direction valve
64 reach the control mouth K of first pressure switch 2, and at this moment the pressure value of the control mouth K of first pressure switch 2 is greater than master controller 9
The first pressure value of middle setting is rotated forward by master controller 9 by the output shaft of the control tensioning motor 4 of motor driver 10.Due to
One end of the output shaft and worm screw 5 that are tensioned motor 4 is sequentially connected, and the other end of worm screw 5 and worm gear 6 are sequentially connected, thus
The output shaft rotating forward of tight motor 4 can drive worm gear 6 to rotate counterclockwise.Again since worm gear 6 is fixedly connected on back door 51, and worm gear
6 center of circle and carriage body 50 and the hinge at back door 51 01 are coaxial, thus back door 51 can be with worm gear 6 around carriage body 50 and back door 51
Hinge 01 rotates counterclockwise.Back door 51 can automatically open in this way.When the opening of back door 51 to open position, due to 51 inverse time of back door
It is limited when needle is rotated to open position by block 1, back door 51 is unable to the rotation of another mistake hour hands at this time, and worm gear 6 can not the rotation of another mistake hour hands
Turn, the revolving speed of the output shaft for being tensioned motor 4 and worm screw 10 can be made to be reduced to 0rpm in this way.The tachometer value of sensor 8 so is also
0rpm, the tachometer value of sensor 8 are equal to the setting speed value 0rpm in master controller 9, pass through motor driver by master controller 9
The output shaft of 10 control tensioning motors 4 stops rotating forward, and at this moment back door 51 is rotated by close stance to open position, i.e. elevating ram 63
Piston rod 63-2 stretch out when back door 51 can automatically open.
When needing to put down the carriage body 50 of dumper, operate hand-operated direction valve 64, make the oil inlet P of hand-operated direction valve 64 with
It executes mouth B to communicate, the pressure oil in hydraulic pump 62 reaches the rod chamber of elevating ram 63, elevating ram 63 through hand-operated direction valve 64
Piston rod 63-2 retract, meanwhile, pressure oil in hydraulic pump 62 can also reach second pressure switch 3 through hand-operated direction valve 64
Control mouth K, at this moment the pressure value of the control mouth K of second pressure switch 3 is greater than the second pressure value set in master controller 9, by
The output shaft reversion that master controller 9 passes through the control tensioning motor 4 of motor driver 10.Output shaft and snail due to tensioning motor 4
One end of bar 5 is sequentially connected, and the other end of worm screw 5 and worm gear 6 are sequentially connected, thus the output shaft reversion for being tensioned motor 4 can
Worm gear 6 is driven to rotate clockwise.Again since worm gear 6 is fixedly connected on back door 51, and the center of circle of worm gear 6 and carriage body 50 and back door
51 hinge 01 is coaxial, thus back door 51 can the hinge 01 with worm gear 6 around carriage body 50 and back door 51 rotate clockwise.In this way
Back door 51 can be automatically closed.It is limited when the closing of back door 51 to close stance by carriage body 50, back door 51 cannot again clockwise at this time
Rotation, worm gear 6 can not rotate clockwise again, and the revolving speed of the output shaft for being tensioned motor 4 and worm screw 10 can in this way be reduced to
0rpm.The tachometer value of sensor 8 so is also 0rpm, and the tachometer value of sensor 8 is equal to the setting speed value in master controller 9
0rpm, by master controller 9 by motor driver 10 control tensioning motor 4 output shaft stop reversion, at this moment back door 51 by
Open position is rotated to close stance, i.e., back door 51 can be automatically closed when the piston rod 63-2 of elevating ram 63 is retracted.It is thus non-
It is often convenient, keep driver's working strength small, work efficiency is high.Also the needs that self-unloading is carried out in narrow space be can satisfy.
