Description

TECHNICAL FIELD

[0001] The utility model relates to a railway ballast unloading car ballast unloading control quantity and flat device belongs to railway construction maintenance technical field. BACKGROUND

[0002] When the ballast railway is completed or the ballast railway is maintained, the ballast unloading car is used to unload the ballast on both sides of the track. The traditional ballast unloading car includes a ballast bucket and a ballast unloading port arranged on both sides of the ballast unloading car and connected with the ballast bucket. The ballast unloading port on both sides is divided into an inner track ballast unloading port and an outer track ballast unloading port. A ballast flow control valve is arranged at the bottom of the ballast bucket. During operation, the ballast unloading car runs along the track, and the ballast is unloaded on both sides of the track. The thickness of the ballast on the track is controlled by the control valve and the speed of the ballast unloading car. The defect of this method is that it is difficult to control the ballast flow by the control valve, and it needs to be perfectly matched with the speed of the car. If the speed of the car is too slow, the ballast will be accumulated. If the speed of the car is too fast or the control of the control valve is too tight, the ballast will be too thin. In order to avoid the accumulation of ballast, the ballast needs to be scraped and leveled. The ballast scraped and leveled is the designed outer material, which is a waste.

[0003] After searching, it is found that the patent document with the application number CN201410309873.0 discloses a ballast unloading and leveling integrated ballast hopper car. The invention discloses a ballast unloading and leveling integrated ballast hopper car, which comprises a car body, a ballast unloading device, a braking device, a car coupler buffer device and a bogie. The ballast unloading device comprises a ballast unloading bottom door, a mechanical transmission device, a wind control ballast unloading device and a manual ballast unloading device. A ballast leveling device is arranged on the car body. The ballast leveling device comprises a ballast leveling plate assembly and a ballast leveling plate lifting driving mechanism. When the ballast leveling plate assembly is lowered by the ballast leveling plate lifting driving mechanism, it moves onto the steel rail. At this time, the lower end surface of the ballast leveling plate assembly is flush with or lower than the upper end surface of the steel rail. When the ballast leveling plate assembly is raised by the ballast leveling plate lifting driving mechanism, it forms a self-locking state. At this time, the ballast leveling plate assembly is separated from the steel rail. When the middle door is operated by the wind to unload the ballast in the middle of the rail to form a ballast pile, the ballast leveling plate assembly in the ballast leveling device can scrape and level the ballast exceeding the height of the track, effectively avoiding the derailment of the vehicle caused by the ballast pile, and realizing the ballast hopper car walking and leveling.

[0004] The patent document solves the problem of how to scrape and level the excessive accumulation of ballast, but cannot solve the problem of how to avoid the excessive accumulation of ballast. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0025] The utility model will be further described in connection with the drawings:

[0026] As Figure 1 , 2As shown, a railway ballast unloading and controlling device for ballast unloading car includes inner and outer discharge pipes 1 and 2 respectively arranged below inner and outer discharge ports 3 and 4, and inner and outer flow control valves 301 and 401 respectively arranged in the inner and outer discharge ports 3 and 4. The inner and outer discharge ports 3 and 4 are communicated with the upper ballast hopper 11. The outer periphery of the inner and outer discharge pipes 1 and 2 is respectively sleeved with inner and outer flow control sleeves 101 and 201, which can slide up and down. The height of the lower end of the inner and outer discharge pipes 1 and 2 is higher than the set height of the ballast surface. In working condition, the height of the lower end of the inner and outer flow control sleeves 101 and 201 is adjusted to be equal to the height of the ballast surface. In this way, when the inner and outer flow control sleeves 101 and 201 are lowered to the lower end of the respective sleeves and the height of the lower end is consistent with the set height of the ballast surface, the inner and outer flow control valves 301 and 401 are fully open, the ballast unloading car is running, and the height of the ballast unloading is limited by the lower end of the inner and outer flow control sleeves 101 and 201, so that the thickness of the ballast unloading can be consistent with the set thickness. When the ballast unloading car is running slowly or even stopped, due to the rough surface of the ballast stone and the limited flowability, even if the inner and outer flow control valves 301 and 401 continue to be fully open, the ballast stone will not flow out due to the limitation of the lower end of the inner and outer flow control sleeves 101 and 201, and there will be no accumulation when the car continues to run, which needs to be scraped and wasted.

[0027] As shown in Figure 3 , 6 , 7, lifting cylinders 5 are arranged at both ends of the inner and outer flow control sleeves 101 and 201, which control the lifting and stopping height of the inner and outer flow control sleeves 101 and 201. The lifting cylinders 5 can be electric cylinders, air cylinders or oil cylinders.

[0028] As shown in Figure 1 , 5 , 7, inclined surface obstacle remover 6 is arranged at both ends of the inner and outer flow control sleeves 101 and 201, which is used to remove hard objects larger than ballast stones. The obstacle removing direction of the inclined surface obstacle remover 6 arranged at both ends of the inner flow control sleeve 101 is the central area between the two tracks 10, and the obstacle removing direction of the inclined surface obstacle remover 6 arranged at both ends of the outer flow control sleeve 201 is the outer direction of the track 10.

[0029] As shown in Figure 3 , 5 , a plurality of unloading assisting notches 2011 are arranged at the lower end surface of the outer side plate of the outer flow control sleeve 201, which is used to expand the outward unloading amount, and its function is to ensure that the collapse of the ballast surface on the outer side of the roadbed can be filled.

[0030] like Figure 4 As shown, a latch 7 is provided on the outer side plate of the outer flow control sleeve 201. A rotatable hook 8 and a cylinder 9 that can push the hook 8 to rotate are provided on the vehicle body 12 above the latch 7. When the outer flow control sleeve 201 is raised, the hook 8 can be hooked onto the latch 7 or pushed away from the latch 7 by the cylinder 9. In this way, the outer flow control sleeve 201 can be prevented from sliding down under gravity due to the loss of pressure of the lifting cylinder 5 when not in operation.

[0031] like Figure 1 As shown, the inner discharge pipe 1 and its inner flow control sleeve 101, as well as the outer discharge pipe 2 and its outer flow control sleeve 201, are all cuboid in shape. The length of the inner discharge pipe 1 and its inner flow control sleeve 101 is less than the length of the outer discharge pipe 2 and its outer flow control sleeve 201, so as to control the discharge ratio of the ballast surfaces on both sides of the track.

[0032] The above embodiments are only used to describe the present invention more clearly, and should not be regarded as limiting the scope of protection covered by the present invention. Any equivalent modifications should be regarded as falling within the scope of protection covered by the present invention.
