Description

Technical Field

[0001] The utility model belongs to the technical field of railways, and particularly relates to a ballast discharging device that can be used on a curved track. Background Art

[0002] When the existing railway ballast cars are laying ballast or replenishing ballast in the ballast bed, the ballast in the ballast bed often appears uneven or even piled up, and sometimes some ballast also appears on the rail surface. To ensure the safety of train operation, it is necessary to level and evenly lay the ballast in the ballast bed and clean the ballast on the rail surface. In the prior art, the top of the ballast pile in the ballast bed can be first leveled with the help of a ballast leveling device, and then the ballast can be cleaned and sorted with the help of a ballast cleaning device, and then the ballast can be evenly laid in the ballast bed.

[0003] There is a disclosed ballast leveling device in the prior art. For example, CN204199125U discloses a ballast leveling device, which includes a plow blade slidably fixed on the vehicle body to rise or fall relative to the vehicle body, and a plow head for leveling the ballast is arranged on the plow blade; a crank rotatably fixed on the vehicle body; a connecting rod, one end of which is rotatably connected to the crank and the other end is rotatably connected to the plow blade; and a driving member for driving the crank to rotate so as to drive the plow blade to rise or fall through the connecting rod and drive the plow head to rise or fall. When performing the ballast leveling operation, the driving member is started to drive the crank to rotate, and the plow blade is driven to descend through the connecting rod, so that the plow head descends. When the vehicle body moves, the plow head can level the ballast, eliminating the need for manual ballast leveling and solving the technical problems of high labor intensity, low efficiency and poor working environment caused by manual ballast leveling.

[0004] It is undeniable that the ballast leveling device disclosed in this patent can indeed achieve the above effects, but it still has certain deficiencies: in order to realize the rise or fall of the plow blade relative to the vehicle body, two guiding grooves need to be opened on the vehicle body, and two guide rail groups are arranged on the plow blade, and the two guide rail groups are respectively arranged in the two guiding grooves to slidably fix the plow blade on the vehicle body. However, during the lifting and lowering process of the plow blade, there will be frictional losses between the guide rail group and the guiding groove. Although wear plates are arranged between the guide rail groups in the ballast leveling device disclosed in this patent to reduce the frictional losses of the plow blade, the wear plates only reduce the frictional losses of the plow blade and cannot avoid them.

[0005] The information disclosed in this background art section is only intended to enhance the overall understanding of the present utility model and should not be regarded as an admission or any form of suggestion that this information constitutes prior art already known to those of ordinary skill in the art.

[0037] The technical solutions of the patent of the present utility model will be clearly and completely described below. Obviously, the described embodiments are part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present utility model.

[0038] Embodiment

[0039] Referring to the attached Figures 1-5 , a ballast discharging device that can be used on a curved track, comprising:

[0040] Vehicle body 1;

[0041] Frame 2, the rear end of the frame 2 is hinged to the vehicle body 1; specifically, a fixed seat 11 is fixed at the rear end of the vehicle body 1, and the rear end of the frame 2 is hinged to the fixed seat 11 through a spherical plain bearing, so that the frame 2 can deflect a certain angle relative to the fixed seat 11; in addition, an anti - detachment chain 21 is fixed at a position near the rear end of the frame 2; the other end of the anti - detachment chain 21 is fixed to the vehicle body 1. When the frame 2 is detached from the fixed seat 11, the anti - detachment chain 21 can prevent the rear end of the frame 2 from falling to the ground. As can be seen from the drawings, the anti - detachment chain 21 is not in a tensioned state; secondly, connecting arms 22 that are symmetrically fixed and inclined forward are provided at the middle positions at both bottoms of the frame 2, and traveling wheels 23 are arranged at the bottoms of the connecting arms 22;

[0042] Lifting cylinder 3 is symmetrically arranged on both sides of the vehicle body 1. Its top is hinged to the vehicle body 1, and its bottom telescopic end is hinged to the middle parts of both sides of the frame 2.

[0043] Plow blade 4 is fixed to the front end of the frame 2. The middle part of the plow blade 4 protrudes outwards in a "V" shape.

[0044] In this embodiment, a fixed arm 12 is fixed to the bottom side of the vehicle body 1. A horizontally arranged traversing cylinder 13 is hinged to the lower end of the fixed arm 12. A hinge seat 24 corresponding to the telescopic end of the traversing cylinder 13 is fixed to the top of the frame 2. The telescopic end of the traversing cylinder 13 is hinged to the hinge seat 24 through a spherical plain bearing.

[0045] In addition, in this embodiment, the bottom telescopic end of the lifting cylinder 3 is hinged to a first connecting seat 31 through a spherical plain bearing. The bottom of the first connecting seat 31 is hinged to the frame 2. The direction in which the telescopic end of the lifting cylinder 3 rotates relative to the first connecting seat 31 is perpendicular to the direction in which the first connecting seat 31 rotates relative to the frame 2. The top of the lifting cylinder 3 is hinged to a second connecting seat 32 through a spherical plain bearing. The top of the second connecting seat 32 is hinged to the vehicle body 1. The direction in which the lifting cylinder 3 rotates relative to the second connecting seat 32 is perpendicular to the direction in which the second connecting seat 32 rotates relative to the vehicle body 1.

[0046] Secondly, in this embodiment, first lifting lugs 41 are symmetrically fixed to the top of the plow blade 4. First connecting chains 14 corresponding to the first lifting lugs 41 are arranged on both sides of the front end of the vehicle body 1. Hooks corresponding to the first lifting lugs 41 are provided at the bottom of the first connecting chains 14. Second lifting lugs 25 are fixed to the middle parts of both sides of the frame 2. Second connecting chains 15 corresponding to the second lifting lugs 25 are arranged on both sides of the middle part of the vehicle body 1. Hooks corresponding to the second lifting lugs 25 are provided at the bottom of the second connecting chains 15.

[0047] In order to stably fix the frame 2 in the locked state, a limit ear 26 is fixed to the middle position of the top of the frame 2. A limit seat 16 is fixed to the bottom of the vehicle body 1. When the telescopic end of the lifting cylinder 3 retracts, the limit ear 26 and the limit seat 16 are in corresponding positions. The limit ear 26 and the limit seat 16 can be fixed by passing a cylindrical pin 5 through the limit ear 26 and the limit seat 16. It is not difficult to understand here that through holes corresponding to the cylindrical pin 5 are provided on the limit ear 26 and the limit seat 16. More specifically, a horizontally telescopic locking cylinder 17 is fixed to the bottom of the vehicle body 1. The telescopic end of the locking cylinder 17 is connected to the cylindrical pin 5.

[0048] During the ballast discharging operation, the lifting oil cylinder 3 is activated. The telescopic end of the lifting oil cylinder 3 extends, the frame 2 rotates around the fixed seat 11, the traveling wheels 23 and the plow blade 4 approach the rail 6, and finally the traveling wheels 23 land on the top surface of the rail 6. It is not difficult to understand here that the traveling wheels 23 are in sliding guiding cooperation with the rail 6. When the traveling wheels 23 roll along the rail 6, they can support the frame 2, reduce the load on the lifting oil cylinder 3, help extend the service life of the lifting oil cylinder 3, and at the same time can also avoid damage to the lifting oil cylinder 3 to a certain extent. After the traveling wheels 23 land on the rail 6, the lifting oil cylinder 3 is locked, and the vehicle body 1 drives the frame 2 and the plow blade 4 to move. During this movement, the plow blade 4 contacts the ballast pile accumulated in the ballast bed, and then can level the top of the ballast pile; at the same time, the plow blade 4 pushes the ballast on the surface of the rail 6 down, preventing the traveling wheels 23 from suddenly rising when rolling over the ballast and causing the traveling wheels 23 to disengage from the rail 6.

[0049] In addition, during the curve operation, the transverse movement oil cylinder 13 is activated. The telescopic end of the transverse movement oil cylinder 13 extends and generates a thrust on the frame 2 through the hinge seat 24. Under the action of this thrust, the frame 2 deflects slightly relative to the fixed seat 11, thereby realizing the curve operation. It should be added here that since the rear end of the frame 2 is hinged to the fixed seat 11 through a spherical bearing, and at the same time the telescopic end of the transverse movement oil cylinder 13 is hinged to the hinge seat 24 through a spherical bearing, during the deflection process of the frame 2, the fixed seat 11 and the transverse movement oil cylinder 13 will not interfere with each other.

[0050] After the operation is completed, the lifting oil cylinder 3 is activated. The telescopic end of the lifting oil cylinder 3 retracts, the frame 2 rotates around the fixed seat 11, and the traveling wheels 23 and the plow blade 4 move away from the rail 6. When the telescopic end of the lifting oil cylinder 3 retracts to the initial position, the lifting oil cylinder 3 is locked. At this time, the positions of the limit seat 16 and the limit ear 26 correspond. The locking oil cylinder 17 is activated, and the telescopic end of the locking oil cylinder 17 extends to generate a thrust on the cylindrical pin 5. Under the action of this thrust, the cylindrical pin 5 penetrates through the limit ear 26 and the limit seat 16 to fix the limit ear 26 and the limit seat 16; then the hook at the bottom of the first connecting chain 14 is hooked on the first lifting lug 41, and the hook at the bottom of the second connecting chain 15 is hooked on the second lifting lug 25 to complete the locking of the frame 2.

[0051] The foregoing description of the specific exemplary embodiments of the present invention is for the purpose of illustration and exemplification. These descriptions are not intended to limit the present invention to the precise forms disclosed, and obviously, many changes and variations can be made in light of the above teachings. The purpose of selecting and describing the exemplary embodiments is to explain the specific principles of the present invention and its practical applications, so that those skilled in the art can implement and utilize various different exemplary embodiments of the present invention as well as various different selections and changes.
