BACKGROUND OF THE INVENTION [0002] A railway ballast truck is an engineering vehicle used for railway ballast transportation and for maintenance and ballasting of new railway lines and existing railway lines. It is specially used for laying ballast for new railway lines and maintaining existing railway lines. In order to improve the efficiency of railway transportation, time for laying ballast and maintenance should be greatly shortened, thus higher requirements are put forward for the efficiencies of transportation and operation as well as safety of railway ballast trucks.

The ballast flattening plow assembly 51 is mounted on the vehicle body 40 and comprises a ballast flattening plow 511, a first ballast flattening plow oil cylinder 516, an oil cylinder upper support 512, a fixed guide plate 517, a rocker 514, a rocker support 515, and a protective cover 518.
[0045] The ballast flattening plow 511 comprises a plow blade 5112, a wear plate 5111, an oil cylinder lower support 5113, a movable guide plate 5114, and a fastener 5115. The wear plate 5111
-9J1WH19AU27456-47D1 is fixed to a lower end of the plow blade 5112 for flattening the ballast. The oil cylinder lower support5113 is fixed to the plow blade 5112, and the first ballast flattening plow oil cylinder 516 is mounted between the oil cylinder upper support 512 and the oil cylinder lower support 5113 to drive the ballast flattening plow 511 to go up and down by its expansion and retraction. The movable guide plate 5114 is fixed to the plow blade 5111 through the fastener 5115.
[0046] The fixed guide plate 517 is fixed on the vehicle body 40, and the movable guide plate 5114 slides in an inner side of the fixed guide plate 517 to ensure that the ballast flattening plow 511 cannot move to both sides. The protective cover 518 can protect the kinematic pair from accidental damage.
[0047] The rocker support 515 is fixed on the vehicle body 40, and the rocker 514 is rotatably connected to the vehicle body 40 at one end, and to the plow blade 5112 at the other end. The rocker 514 is a parallel four-connecting rod mechanism consisting of two layers (i.e. one upper layer and one lower layer) of two-force bars which are parallel to each other and have equal lengths, thus the plow blade 5112 can be maintained to make parallel movements in a vertical plane all the time and a lower plane of the plow blade 5112 can be always horizontal.
[0048] The first ballast flattening plow oil cylinder 516 has been provided with a hydraulic lock to prevent the ballast flattening plow 511 from accidental drop caused due to an accidental extending of the first ballast flattening plow oil cylinder 516.
[0049] Further, in order to improve safety and prevent the ballast flattening plow 511 from falling accidentally, a locking device 513 is additionally provided which is mounted on the vehicle body 40. As shown in FIG. 4, the locking device 513 includes a lock tongue 5131, a plate spring 5132, a plate spring holder 5133, and a mounting base 5134. The mounting base 5134 is fixed to the vehicle body 40. The plate spring 5132 and the mounting base 5134 are fixedly connected by the plate spring holder 5133, and the lock tongue 5131 is fixed to the plate spring 5132. The plate spring 5132 functions to rebound and support, and press the lock tongue 5131 to be embedded into a locking hole on the movable guide plate 514 to realize a locking of the ballast flattening plow 511. A working surface of the lock tongue 5131 is of an inclined wedge structure, and the self-weight of the ballast flattening plow 511 cannot overcome a frictional force of the inclined wedge structure of the working surface of the lock tongue 5131, so the ballast flattening plow 511 cannot overcome the locking force by its own weight. However, in normal operation, when an external thrust of the first ballast flattening plow cylinder 516 is much larger than the frictional force of the inclined wedge structure of the working surface of the lock tongue 5131, unlocking can be realized.
-10J1WH19AU27456-47D1 [0050] When the first ballast flattening plow cylinder 516 retracts, the ballast flattening plow 511 gradually rises, and the movable guide plate 5114 when rising, slides along a lower working surface of the lock tongue 5131 to overcome the resilience of the plate spring 5132, thus the lock tongue 5131 retreats and exits a first locking hole. When rising to the highest point, the lock tongue 5131, under the resilience of the plate spring 5132, is again embedded into a second locking hole on the movable guide plate 514, achieving a locking of the ballast flattening plow 511.
[0051] The ballast flattening plow assembly 53 and the ballast flattening plow assembly 51 have the same structure, thus for ease of distinction, the oil cylinder of the ballast flattening plow assembly 51 is called as a second ballast flattening plow oil cylinder 536.
[0052] Referring to Fig. 5, in this embodiment, in order to sweep the rail after ballast flattening, the ballast flattening device 50 further comprises steel rail sweepers 52 and 54. The ballast flattening plow assembly 51 is used for scraping ballast around the rail flat, and the steel rail sweeper 52 sweeps ballast on the top of the steel rail clear.
[0053] The steel rail sweeper 52 includes a fixing base 521, a first sweeper oil cylinder 522, a guide plate 523 and a sweeping rod 524. The fixing base 521 is fixed on the vehicle body 40, and the first sweeper oil cylinder 522 is mounted between the fixing base 521 and the guide plate 523. The guide plate 523 can slide relative to the fixing base 521, and the sweeping rod 524 is mounted on the guide plate 523.
[0054] When the first sweeper oil cylinder 522 extends out, it pushes the guide plate 523 and the sweeping rod 524 to descend so as to sweep the steel rail by the sweeping rod 524. Upon the completion of the sweeping, the first sweeper oil cylinder 522 retracts to pull the guide plate 523 and the sweeping rod to rise, such that the first sweeper oil cylinder 522 is in a non-operating state.
[0055] The steel rail sweeper 54 and the steel rail sweeper 52 have the same structure, thus for ease of distinction, the oil cylinder of the steel rail sweeper 54 is called as a second sweeper oil cylinder 542.
[0056] Fig. 1 shows that a vehicle moves leftwards to flatten ballast on the left side, at this time, a ballast flattening plow assembly 53 at the left side and the sweeper 52 on its back side descend. A ballast flattening plow assembly 51 at the right side in a non-operating state and the left side sweeper 54 on its back side are still in a raised state.
[0057] Conversely, when the vehicle moves rightwards to flatten the ballast on the right side, the right side ballast flattening plow assembly 51 and the left side sweeper 54 on its back side will
-11J1WH19AU27456-47D1 descend. The non-operating left side ballast flattening plow assembly 53 and the right side sweeper on its back side will be in the raised state.
[0058] The existing ballast flattening vehicle usually has only one ballast flattening plow, and the hydraulic valve is manually manipulated, which is really easy. However it can only perform ballast flattening in one direction, and if it is needed to perform a roundtrip ballast flattening, the vehicle needs to be turned around, which is troublesome. There is a lot of dust during ballast flattening, and an operator standing on the vehicle will be covered all over with dust, which is bad for the operator’s health. In the present disclosure, two ballast flattening plows are mounted symmetrically in the front and back of the vehicle, which can perform ballast flattening in two directions, thus the vehicle does not need to turn around when performing the roundtrip ballast flattening, as long as the ballast flattening plow is changed, thus saving time and material resources. When remote control is adopted, the operator can be at a certain distance from the ballast flattening plow, thus the dust produced during ballast flattening will have less influence on the operator.
[0059] The ballast flattening device 50 further comprises a hydraulic system for controlling operations of the first ballast flattening plow oil cylinder 516, the second ballast flattening plow oil cylinder 536, the first sweeper oil cylinder 522 and the second sweeper oil cylinder 542, as shown in Figs. 6 and 7 which are two parts of one figure, and the line ports marked with A, B, C, D, E, F, G, H and I in Fig. 6 are connected to the line ports marked with corresponding marks in Fig. 7.

The second interlocking valve 17.2 is connected to an inlet of the fifth shuttle valve, the first three-position four-way pneumatic hydraulic valve 18.1 and the second three-position four-way pneumatic hydraulic valve 18.2. Outlets of the fifth shuttle valve 16.5 and the sixth shuttle valve 16.6 are respectively connected to two inlets of the seventh shuttle valve 16.7, and an outlet of the seventh shuttle valve 16.7 is connected to the two-position two-way pneumatic control valve 23 to control an opening or closing thereof.
[0064] The two-position two-way pneumatic control valve 23 is connected at one end to the air source and at the other end to the throttle valve 24 and then to the hydraulic station.

[0065] In this embodiment, both manual control and electric control can be used for the hydraulic structure, and in other embodiments, one of the manual control and electric control may be directly adopted as follows:

-14J1WH19AU27456-47D1 [0069] In addition, an overflow valve 19 is further disposed between the first three-way ball valve
20.1 and the second three-position four-way pneumatic hydraulic valve 18.2.
[0070] The above described is the hydraulic structure in which one sweeper oil cylinder and one ballast flattening plow oil cylinder can be controlled at the same time. To realize controlling one sweeper oil cylinder or one ballast flattening plow oil cylinder separately, the hydraulic system further comprises: a third three-position five-way median release manual valve 14.3, a fifth solenoid valve 15.5, a sixth solenoid valve 15.6, an eighth shuttle valve 16.8, a ninth shuttle valve 16.9, a third interlocking valve 17.3, a fourth interlocking valve 17.4, a fifth interlocking valve 17.5 and a sixth interlocking valve 17.6.
[0071] At this time, an outlet of the first shuttle valve 16.1 is connected to the fourth three-position four-way pneumatic hydraulic valve 18.4 through the sixth interlocking valve 17.6; the first interlocking valve 17.1 is connected to the fifth interlocking valve 17.5 and then to the fourth threeposition four-way pneumatic hydraulic valve 18.4; an outlet of the third shuttle valve 16.3 is connected to the fourth interlocking valve 17.4 and then to the second three-position four-way pneumatic hydraulic valve 18.2; the second interlocking valve 17.2 is connected to the third interlocking valve 17.3 and then to the second three-position four-way pneumatic hydraulic valve
18.2. The third three-position five-way median release manual valve 14.3, the fifth solenoid valve 15.5 and the sixth solenoid valve 15.6 are also connected to the air source simultaneously, and one inlet of the eighth shuttle valve 16.8 is connected to the third three-position five-way median release manual valve 14.3, and another inlet thereof is connected to the fifth solenoid valve 15.5; one inlet of the ninth shuttle valve 16.9 is connected to the third three-position five-way median release manual valve 14.3, and another inlet thereof is connected to the sixth solenoid valve 15.6.

The operating principle of the hydraulic system will be introduced in detail below:
[0072] the air source includes a ball valve 4, an air filter 5, a check valve 6, a release valve 7, a drain butterfly valve 8, an exhaust ball valve 9, a filter pressure-reducing valve 10, a lubricator 11, an exhaust ball valve 12, and a filter pressure-reducing valve 13, and an air storage tank 33.
[0073] The ball valve 4, air filter 5 and check valve 6 are connected sequentially, and three paths are led out from the check valve 6, wherein a first path is connected to the exhaust ball valve 9, filter pressure-reducing valve 10, and lubricator 11 in sequence before being connected to the two-position
-15J1WH19AU27456-47D1 two-way pneumatic control valve 23; a second path is connected to the drain butterfly valve 8, air storage tank 33, release valve 7 in sequence and then connected to the air storage tank 33; a third path is connected to the exhaust ball valve 12 and filter pressure reducing valve 13 in sequence. [0074] An air source connected with external compressed air is divided into three paths after passing through the ball valve 4, the air filter 5 and the check valve 6, i.e., upper path, middle path and lower path. The upper path passes through a control air source processing pipeline composed of the exhaust ball valve 12 and the filter pressure-reducing valve 13 to provide the compressed air with stable and low pressure and small flow rate to the control valves in the system so as to control transposition of various control valves. The middle path is connected to the air storage tank to serve as a buffer and emergency air source. The lower path is connected to a dynamic air source processing pipeline composed of the exhaust ball valve 9, the filter pressure-reducing valve 10 and the lubricator 11 to provide compressed air with stable and high pressure and large flow rate to the air motor to drive a rotation thereof.
[0075] The hydraulic station includes an air motor 26, a hydraulic pump 25, an oil suction filter 27, a hand oil pump 28, a return oil filter 29, a liquid level thermometer 30, an air filter 31, an oil discharge ball valve 32, etc.
[0076] The first interlocking valve 17.1, second interlocking valve 17.2, third interlocking valve 173, fourth interlocking valve 17.4, fifth interlocking valve 17.5 and sixth interlocking valve 17.6 are used to enable connection of only one path at a time, while keeping the remaining paths disconnected.
[0077] A default position of the two-position two-way pneumatic control valve 23 is a shut-off path, in which air is not supplied to the air motor 26 and the air motor does not rotate. Only when any one of the first three-position five-way median release manual valve 14.1, the third three-position fiveway median release manual valve 14.3, the second three-position five-way median release manual valve 14.2, the first solenoid valve 15.1, the second solenoid valve 15.2, the third solenoid valve
15.3, the fourth solenoid valve 15.4, the fifth solenoid valve 15.5 and the sixth solenoid valve 15.6 is transposed to switch on the air path, the compressed air in a control air path enters the two-position two-way pneumatic control valve 23 through the first shuttle valve 16.1, the second shuttle valve 16.2, the third shuttle valve 16.3, the fourth shuttle valve 16.4, the fifth shuttle valve 16.5, the sixth shuttle valve 16.6, the seventh shuttle valve 16.7, the eighth shuttle valve 16.8 and the ninth shuttle valve 16.9 to transpose the two-position two-way pneumatic control valve 23 from the default position (shut-off path) into the switch-on path, can the compressed air in a dynamic air path enters
-16J1WH19AU27456-47D1 the air motor 26 through the two-position two-way pneumatic control valve 23 and the throttle valve 24 to drive the air motor 26 to rotate. When the first three-position five-way median release manual valve 14.1, the second three-position five-way median release manual valve 14.2, and the third threeposition five-way median release manual valve 14.3 are transposed to the median position, or the first solenoid valve 15.1, the second solenoid valve 15.2, the third solenoid valve 15.3, the fourth solenoid valve 15.4, the fifth solenoid valve 15.5 and the sixth solenoid valve 15.6 are transposed to the right position, the compressed air in the control air path enters the two-position two-way pneumatic control valve 23 through the first shuttle valve 16.1, the second shuttle valve 16.2, the third shuttle valve 16.3, the fourth shuttle valve 16.4, the fifth shuttle valve 16.5, the sixth shuttle valve 16.6, the seventh shuttle valve 16.7, the eighth shuttle valve 16.8 and the ninth shuttle valve 16.9, and the two-position two-way pneumatic control valve 23 is immediately switched from the switch-on path to the default position (shut-off path). The compressed air in the dynamic air path is cut off by the two-position two-way pneumatic control valve 23 and the air motor 26 immediately stops rotating. The two-position two-way pneumatic control valve 23 can make the air motor 26 to rotate only when it is necessary for the oil cylinder to work and to remain still at other times, thus avoiding unnecessary rotation to save energy and guarantee safety.
[0078] The throttle valve 24 is adjustable to regulate a flow of compressed air entering the air motor 26, thereby adjusting a rotational speed of the air motor 26. Meanwhile, amplitude of the compressed air entering the air motor 26 can be reduced, thus the rotational stability of the air motor 26 can be improved. When the two-position two-way pneumatic control valve 23 is converted into the switchon path, the compressed air enters the air motor 26 through the throttle valve 24. Various hydraulic oil cylinders all have a balancing valve that can keep self-locking.
[0079] With respect to three-position five-way median release manual valves 14.1, 14.2 and 14.3, the median position is a state in which the input is disconnected and the output is connected to the atmosphere, i.e. the input and output are disconnected.
[0080] A handle of the three-position five-way median release manual valve 14.1 is pulled by hand to transpose the valve to the left position, then compressed air enters the shuttle valve 16.3 through the valve 14.1, and an intake pipe of the two-position three-way solenoid valve 15.3 is shut off so that the two-position three-way solenoid valve 15.3 is disabled and only manual control can be used. Then the air is divided into three paths: an upper path passes through the interlocking valve 17.4 to reach a right side of the three-position four-way pneumatic hydraulic valve 18.2 to switch the valve
18.2 from the median position into the right position, then high-pressure oil from the hydraulic
-17J1WH19AU27456-47D1 station enters a rodless cavity of the second sweeper oil cylinder 542 through the valve 18.2 to drive a piston rod of the second sweeper oil cylinder 542 to extend out, and the steel rail sweeper is lowered to a sweeping position. A middle path of the compressed air enters a right side of the threeposition four-way pneumatic hydraulic valve 18.1 to switch the valve 18.1 into the right position, high-pressure oil from the hydraulic station enters a rodless cavity of the first ballast flattening plow oil cylinder 516 through the valve 18.1 to drive a piston rod of the first ballast flattening plow oil cylinder 516 to extend out, and a first group of ballast flattening plows are lowered to a ballast flattening position. A lower path enters the two-position two-way pneumatic control valve 23 through the shuttle valves 16.5 and 16.7 to switch the two-position two-way pneumatic control valve 23 from the default position (shut-off path) into the switch-on path, and the compressed air from an air source processing device enters the air motor 26 through the throttle valve 24 to drive the air motor to rotate and drive the hydraulic pump 25 to provide high-pressure oil to the second sweeper oil cylinder 542 and the first ballast flattening plow oil cylinder 516 through the pipeline and valves. [0081] The handle of the valve 14.1 is pulled by hand to transpose it to the right position, then compressed air enters the shuttle valve 16.4 through the valve 14.1, and an intake pipe of the twoposition three-way solenoid valve 15.4 is shut off, so that the two-position three-way solenoid valve 15.4 is disabled and only manual control can be used. An upper path of the compressed air pushes the interlocking valve 17.1 to the shut-off path. The upper path after passing through the interlocking valve 17.2 is divided into three paths: an upper path passes through the interlocking valve 17.3 to reach a left side of the three-position four-way pneumatic hydraulic valve 18.2 to switch the valve
18.2 from the median position into the left position, and high-pressure oil from the hydraulic station enters a rod cavity of the second sweeper oil cylinder 542 through the valve 18.2 to drive the piston rod of the second sweeper oil cylinder 542 to retract and the steel rail sweeper is lifted to a nonsweeping position. A middle path reaches a left side of the three-position four-way pneumatic hydraulic valve 18.1 to switch the valve 18.1 into the left position from the median position, and high-pressure oil from the hydraulic station enters a rod cavity of the first ballast flattening plow oil cylinder 516 through the valve 18.1 to drive the piston rod of the first ballast flattening plow oil cylinder 516 to retract, and a first group of ballast flattening plows are raised to the non-ballastflattening position. A lower path enters the two-position two-way pneumatic control valve 23 through the shuttle valves 16.5 and 16.7 to switch the valve 23 from the default position (shut-off path) into the switch-on path, and the compressed air from an air source processing device enters the air motor 26 through the throttle valve 24 to drive the air motor to rotate and drive the hydraulic
-18J1WH19AU27456-47D1 pump 25 to provide high-pressure oil to the second sweeper oil cylinder 542 and the first ballast flattening plow oil cylinder 516 through the pipeline and valves.
[0082] A handle of the valve 14.2 is pulled by hand to transpose the valve to the left position, then compressed air enters the shuttle valve 16.1 through the valve 14.1, and an intake pipe of the twoposition three-way solenoid valve 15.1 is shut off, so that the two-position three-way solenoid valve
15.1 is disabled and only manual control can be used. Then the air is divided into three paths: an upper path passes through the interlocking valve 17.6 to reach a right side of the three-position fourway pneumatic hydraulic valve 18.4 to switch the valve 18.4 from the median position into the right position, and then high-pressure oil from the hydraulic station enters a rodless cavity of the first sweeper oil cylinder 522 through the valve 18.4 to drive a piston rod of the first sweeper oil cylinder 522 to extend out, and the steel rail sweeper is lowered to the sweeping position. A middle path of the compressed air enters a right side of the three-position four-way pneumatic hydraulic valve 18.3 to switch the three-position four-way pneumatic hydraulic valve 18.3 into the right position, and then high-pressure oil from the hydraulic station enters a rodless cavity of the second ballast flattening plow oil cylinder 536 through the three-position four-way pneumatic hydraulic valve 18.3 to drive a piston rod of the second ballast flattening plow oil cylinder 536 to extend out, and a second group of ballast flattening plows are lowered to the ballast flattening position. A lower path enters the twoposition two-way pneumatic control valve 23 through the shuttle valves 16.6 and 16.7 to switch the two-position two-way pneumatic control valve 23 from the default position (shut-off path) into the switch-on path, and the compressed air from an air source processing device enters the air motor 26 through the throttle valve 24 to drive the air motor to rotate and drive the hydraulic pump 25 to provide high-pressure oil to the first sweeper oil cylinder 522 and the second ballast flattening plow oil cylinder 536 through the pipeline and valves.
[0083] A handle of the valve 14.2 is pulled by hand to transpose the valve to the right position, then compressed air enters the shuttle valve 16.2 through the valve 14.2, and an intake pipe of the twoposition three-way solenoid valve 15.2 is shut off, so that the two-position three-way solenoid valve
15.2 is disabled and only manual control can be used. An upper path of the compressed air pushes the interlocking valve 17.2 to the shut-off path. The upper path after passing through the interlocking valve 17.1 is divided into three paths: an upper path passes through the interlocking valve 17.5 to reach a left side of the three-position four-way pneumatic hydraulic valve 18.4 to switch the threeposition four-way pneumatic hydraulic valve 18.4 from the median position into the left position, and then high-pressure oil from the hydraulic station enters a rod cavity of the first sweeper oil
-19J1WH19AU27456-47D1 cylinder 522 through the valve 18.4 to drive the piston rod of the first sweeper oil cylinder 522 to retract and the steel rail sweeper is lifted to the non-sweeping position. A middle path reaches a left side of the three-position four-way pneumatic hydraulic valve 18.3 to switch the valve 18.3 into the left position from the median position, and then high-pressure oil from the hydraulic station enters a rod cavity of the second ballast flattening plow oil cylinder 536 through the valve 18.3 to drive the piston rod of the second ballast flattening plow oil cylinder 536 to retract, and a second group of ballast flattening plows are raised to the non-ballast-flattening position. A lower path enters the twoposition two-way pneumatic control valve 23 through the shuttle valves 16.6 and 16.7 to switch the valve 23 from the default position (shut-off path) into the switch-on path, and the compressed air from an air source processing device enters the air motor 26 through the throttle valve 24 to drive the air motor to rotate and drive the hydraulic pump 25 to provide high-pressure oil to the second sweeper oil cylinder 542 and the second ballast flattening plow oil cylinder 536 through the pipeline and valves.
[0084] A handle of the valve 14.3 is pulled by hand to transpose the valve to the left position, then compressed air enters the shuttle valve 16.9 through the valve 14.3, and an intake pipe of the twoposition three-way solenoid valve 15.6 is shut off, so that the two-position three-way solenoid valve 15.6 is disabled and only manual control of the valve can be used. Meanwhile, the interlocking valves 17.5 and 17.6 are switched to the shut-off position so that the three-position four-way pneumatic hydraulic valve 18.4 has no compressed air in control ports on both sides thereof, and remains at the median position. No hydraulic oil comes into or out of the first sweeper oil cylinder 522, so the first sweeper cylinder 522 is actually locked.
[0085] The handle of the valve 14.3 is pulled by hand to transpose it to the right position, then compressed air enters the shuttle valve 16.8 through the valve 14.3, and an intake pipe of the twoposition three-way solenoid valve 15.5 is shut off, so that the two-position three-way solenoid valve 15.5 is disabled and only manual control of the valve can be used. Meanwhile, the interlocking valves 17.3 and 17.4 are switched to the shut-off position so that the three-position four-way pneumatic hydraulic valve 18.2 has no compressed air in control ports on both sides thereof, and remains at the median position. No hydraulic oil comes into or out of the second sweeper cylinder oil 542, either, so the second sweeper oil cylinder 542 is actually locked.
[0086] When the three-position five-way median release manual valve 14.3 is at the median position, the ballast flattening plow oil cylinders and the sweeper oil cylinders can also be simultaneously manipulated while manipulating the valves 14.1 and 14.2. When the three-position five-way median
-20J1WH19AU27456-47D1 release manual valve 14.3 is not at the median position, the ballast flattening plow oil cylinders can be manipulated while manipulating the valves 14.1 and 14.2, but the sweeper oil cylinders cannot be manipulated. Thus the actual function is manipulating the sweeper oil cylinders only.
[0087] The above is the principle of manual control. As long as the three-position five-way median release manual valves 14 are manipulated and the three-position five-way median release manual valves 14 are not at the median position, intake pipes of the two-position three-way solenoid valves 15 are immediately shut off, so that remote control does not work and only manual control is feasible. [0088] When the three-position five-way median release manual valves 14 are not manipulated and the three-position five-way median release manual valves 14 are all at the median position, electrical signals are sent to the solenoid valves 15 through a remote control system to drive the solenoid valves 15 to switch from the default state (shut-off) into the switch-on state, then the remote control works and the manual control is ineffective.
[0089] When the solenoid valve 15.1 is in the switch-on state, compressed air enters the shuttle valve 16.1 through the valve 15.1, and the air path between the shuttle valve 16.1 and the threeposition five-way median release manual valve 14.2 is shut off, such that the three-position five-way median release manual valve 14.2 can no longer function to manipulate. The compressed air enters subsequent pipes after passing through the valve 15.1 and the shuttle valve 16.1, and its subsequent flow direction and function are the same as those of pulling the handle of the valve 14.2 by hand to transpose it to the left position.
[0090] When the solenoid valve 15.1 is in the switch-on state, compressed air enters the shuttle valve 16.2 through the valve 15.2, and the air path between the shuttle valve 16.2 and the threeposition five-way median release manual valve 14.2 is shut off, such that the three-position five-way median release manual valve 14.2 can no longer function to manipulate. The compressed air enters subsequent pipes after passing through the valve 15.2 and the shuttle valve 16.2, and its subsequent flow direction and function are the same as those of pulling the handle of the valve 14.2 by hand to transpose it to the right position.
[0091] When the solenoid valve 15.3 is in the switch-on state, compressed air enters the shuttle valve 16.3 through the valve 15.3, and the air path between the shuttle valve 16.3 and the threeposition five-way median release manual valve 14.1 is shut off, such that the three-position five-way median release manual valve 14.1 can no longer function to manipulate. The compressed air enters subsequent pipes after passing through the valve 15.3 and the shuttle valve 16.3, and its subsequent
-21J1WH19AU27456-47D1 flow direction and function are the same as those of pulling the handle of the valve 14.1 by hand to transpose it to the left position.
[0092] When the solenoid valve 15.4 is in the switch-on state, compressed air enters the shuttle valve 16.4 through the valve 15.4, and the air path between the shuttle valve 16.4 and the threeposition five-way median release manual valve 14.1 is shut off, such that the three-position five-way median release manual valve 14.1 can no longer function to manipulate. The compressed air enters subsequent pipes after passing through the valve 15.4 and the shuttle valve 16.4, and its subsequent flow direction and function are the same as those of pulling the handle of the valve 14.1 by hand to transpose it to the right position.
[0093] When the solenoid valve 15.5 is in the switch-on state, compressed air enters the shuttle valve 16.8 through the valve 15.5, and the air path between the shuttle valve 16.8 and the threeposition five-way median release manual valve 14.3 is shut off, such that the three-position five-way median release manual valve 14.3 can no longer function to manipulate. The compressed air enters subsequent pipes after passing through the valve 15.5 and the shuttle valve 16.8, and its subsequent flow direction and function are the same as those of pulling the handle of the valve 14.3 by hand to transpose the valve to the right position.
[0094] When the solenoid valve 15.6 is in the switch-on state, compressed air enters the shuttle valve 16.9 through the valve 15.6, and the air path between the shuttle valve 16.9 and the threeposition five-way median release manual valve 14.3 is shut off, such that the three-position five-way median release manual valve 14.3 can no longer function to manipulate. The compressed air enters subsequent pipes after passing through the valve 15.6 and the shuttle valve 16.9, and its subsequent flow direction and function are the same as those of pulling the handle of the valve 14.3 by hand to transpose it to the left position.
[0095] Both remote control and manual control require that the three-way ball valve must be in the right position, at this time, various three-position four-way pneumatic hydraulic valves 18 are connected to corresponding rod cavities of the oil cylinders and are disconnected from the hand oil pump 28, so they cannot supply oil to the oil cylinders.
[0096] When the hydraulic station is unable to supply oil to the oil cylinders due to various reasons of failure, the three-way ball valve 20 is switched from the right position to the left position, and the three-position four-way pneumatic hydraulic valve 18 is disconnected from the rod cavity of the corresponding oil cylinder, and the hand oil pump 28 is connected to the rod cavity of various cavities, and then the hand oil pump 28 is hand operated to supply oil to the rod cavity of the oil
-22J1WH19AU27456-47D1 cavity so as to drive the ballast flattening hydraulic oil cylinder to retract, and the ballast flattening plow rises to the non-ballast-flattening position to drive the steel rail sweeping hydraulic oil cylinder to retract so as to lift the steel rail sweeper to the non-sweeping position. The specific relationships are that the first three-way ball valve 20.1 controls the first ballast flattening plow oil cylinder 516; the second three-way ball valve 20.2 controls the second sweeper oil cylinder 542; the third threeway ball valve 20.3 controls the second ballast flattening plow oil cylinder 536; and the fourth threeway ball valve 20.4 controls the first sweeper oil cylinder 522.
[0097] After performing the emergency procedures, the corresponding three-way ball valve must be switched to the right position.
[0098] The ballast flattening vehicle and ballast flattening device of the present application use the ballast flattening plow oil cylinder to control descending of the ballast flattening plow so as to flatten ballast, and use the sweeper oil cylinder to control descending of the sweeping rod so as to sweep, thus manual ballast flattening is not needed, and the ballast flattening efficiency is improved, and the technical problem of high labor intensity, low efficiency and harsh environment in the prior art caused by manual ballast flattening is solved. The present application provides a ballast flattening device and a ballast flattening vehicle having the ballast flattening device.
