Description

Technical Field

[0001] This invention relates to the technical field of railway material loading and unloading, and in particular to a multi-functional material car for automatic railway loading and unloading. Background Technology

[0002] In the process of railway transportation, it is often necessary to transport large quantities of bulk materials (such as crushed stone, ballast, etc.). The bulk material transport car in railway transportation equipment is a special type of railway transport vehicle used for transporting bulk materials.

[0003] For example, the WY-100 type material car is relatively large, about 27 meters long, and has self-propelled capability. However, when moving between sites, it needs to be transported by being attached to the rear of a freight train on the same line. During transportation, because the inclined section of the conveyor belt is suspended in the air, a support frame is required to support the inclined section of the conveyor belt. Therefore, an additional flatbed car is needed to place the support frame on the flatbed car, which increases the overall weight of the train, making the transportation of the material car inconvenient and increasing the operating cost. Summary of the Invention

[0004] To address the problems existing in the prior art, the present invention provides a multi-functional material car for automated loading and unloading on railways that facilitates transportation and saves energy.

[0005] The present invention provides a multi-functional material car for automatic loading and unloading on railways, which adopts the following technical solution: A multi-functional material car for automatic loading and unloading on railway includes a throwing belt conveyor, a storage belt conveyor, a translation trolley, and a railway flatbed transport car. The storage belt conveyor is detachably connected to the railway flatbed transport car. The translation trolley is located inside the storage belt conveyor and can move along the length of the storage belt conveyor. The throwing belt is installed above the translation trolley and moves with the translation trolley. The material throwing belt conveyor includes a belt frame and a material throwing belt mounted on the belt frame. The belt frame includes a horizontal frame and an inclined frame rotatably connected to the horizontal frame. A lifting mechanism is installed on the side wall of the belt frame to drive the inclined frame to rotate, thereby keeping the horizontal frame and the inclined frame horizontal or setting the inclined frame and the horizontal frame at an obtuse angle. When not in operation, the horizontal frame and the inclined frame remain horizontal, and the entire belt frame can be placed inside the material storage belt conveyor with the translation trolley. When in operation, the translation trolley moves the material throwing belt to the outside of the material storage belt conveyor, and the inclined frame and the horizontal frame are set at an obtuse angle.

[0006] Optionally, the material throwing belt conveyor also includes a first belt drive mechanism, which includes a geared motor, a sprocket drive shaft, and a tail drive shaft. The sprocket drive shaft is located at the end of the inclined frame away from the horizontal frame and is rotatably connected to the inclined frame. The geared motor is mounted on the side wall of the inclined frame and drives the sprocket drive shaft to rotate. Two separately arranged first sprockets are mounted on the sprocket drive shaft. The tail drive shaft is rotatably connected to the horizontal frame and has two second sprockets mounted on it. A conveyor chain is provided between the first sprockets and the second sprockets. A first fixed crossbeam that can maintain the distance between the two parallel conveyor chains is connected between them. The first fixed crossbeam is fixed to the material throwing belt.

The connecting crossbeam is fixed to the material throwing belt. Support rails are installed on the inner walls of the inclined frame and the horizontal frame. When the conveyor chain deviates from the center of the first sprocket and the second sprocket, the limiting wheel will contact the support rail before the conveyor chain engages with the sprocket, thus guiding the conveyor chain back to the center position of the sprocket.

[0008] Optionally, the material throwing belt conveyor also includes a chain wheel mechanism that flattens the local warping phenomenon that occurs at the angle change point of the material throwing belt when the inclined frame and the horizontal frame are set at an obtuse angle.

[0009] Optionally, the chain pressing mechanism includes a chain pressing roller and a belt pressing block. Multiple belt pressing blocks are installed on the inner walls of the horizontal frame and the inclined frame close to each other. The chain pressing roller is rotatably connected to the rotating shaft that is rotatably connected to the horizontal frame and the inclined frame. The belt pressing block is located above the chain pressing roller, and the upper part of the conveyor chain is located between the belt pressing block and the chain pressing roller.

[0010] Optionally, a tensioning mechanism is provided at the end of the horizontal frame away from the inclined frame. The tensioning mechanism includes a fixed frame, a shaft end support, a first tension spring, and a second tension spring. The fixed frame is installed on the horizontal frame and has a second inner groove. The shaft end support is slidably connected in the second inner groove, and the tail drive shaft is installed on the shaft end support. A fixing screw is installed at one end of the shaft end support, and the end of the fixing screw away from the shaft end support passes through the fixed frame. The inner wall of the fixed frame and the shaft end support are fixed with the second tension spring. An adjusting screw is installed at the other end of the shaft end support, and the adjusting screw passes through the fixed frame. An abutment plate is slidably provided on the adjusting screw, and the first tension spring is fixed between the abutment plate and the fixed frame. An adjusting nut is provided at the end of the abutment plate away from the first tension spring.

[0011] Optionally, the storage belt conveyor includes a storage trough frame, a storage belt, and a second belt drive mechanism for driving the storage belt to rotate. The storage trough frame includes a square tube skeleton and a frame base fixed below the square tube skeleton. The frame base is connected to a railway flatbed transport vehicle. Frame side plates are fixed on the inner wall of the square tube skeleton. Chain track seats are provided at the bottom of both ends of the frame side plates. The second belt drive mechanism is installed on the chain track seats. The storage belt is installed on the frame side plates. A tail plate is welded and fixed to the tail of the frame side plates. Storage trough liners can be detachably connected to both the frame side plates and the tail plates.

[0012] Optionally, the translation trolley includes a frame, with wheels mounted on both sides of the frame. An inner longitudinal beam for the wheels to travel on is provided on the frame base. A lower connecting seat is mounted on the frame. A slewing support connecting seat is fixed at the bottom of the horizontal frame. The slewing support connecting seat is rotatably connected to the lower connecting seat. A worm gear reducer that drives the slewing support connecting seat to rotate is mounted on the frame. A trolley drive mechanism that drives the translation trolley to move on the frame base is provided on the frame.

[0013] Optionally, a sector-shaped pressure roller seat is fixed on the frame, and multiple ballast rollers are rotatably connected to the sector-shaped pressure roller seat. The slewing support connecting seat has a flange upper surface, and the ballast rollers are located above the flange upper surface of the slewing support connecting seat with a gap.

[0014] Optionally, the trolley drive mechanism includes a trolley drive shaft, a third sprocket, and a fourth sprocket. The fourth sprocket is mounted on the trolley drive shaft. A vertical axis geared motor that drives the trolley drive shaft and the third sprocket is mounted on the frame. A steel plate chain assembly that allows the third sprocket and the fourth sprocket to move is mounted on the frame base.

[0015] Compared with the prior art, the present invention has the following technical effects: 1. The storage belt conveyor can be detachably connected to a railway flatbed transport car. When a material car is needed, the storage belt conveyor, the throwing belt conveyor, and the translating trolley can be placed on a freight car for land transportation, which is convenient and reduces transportation costs. When not in operation, the horizontal frame and the inclined frame remain horizontal, and the entire belt frame can be placed inside the storage belt conveyor along with the translating trolley. This reduces the space occupied by the throwing belt conveyor, and the inclined frame does not need to be supported during transportation.

[0016] 2. The setting of limit wheels and support rails can ensure accurate meshing between the conveyor chain and the sprocket, thus ensuring the normal operation of the material throwing belt.

[0017] 3. The sprocket mechanism can flatten the local warping phenomenon that occurs in the part of the material throwing belt where the angle changes.

[0018] 4. The tensioning mechanism can tension the conveyor chain, thereby tensioning the material throwing belt.

[0019] 5. The fan-shaped pressure roller seat and ballast roller can rotate the support seat to apply downward pressure and prevent the end of the material throwing belt from tilting up. Attached Figure Description

[0052] The diesel generator set 5 and control box 6 provide power, control, lighting, and remote control functions for the material throwing belt conveyor 1, the material storage belt conveyor 2, and the translation trolley 3. The hydraulic control station 7 mainly provides power for the lifting and rotation of the material throwing belt conveyor 1. The diesel generator set 5 and control box 6 are mounted on the railway flatbed transport car 4. The hydraulic control station 7 is mounted on the frame 31 of the translation trolley 3.

[0053] The material cart of the present invention travels and transports on the railway via a railway flatbed transport car 4. The material throwing belt conveyor 1 can travel on the steel plate chain assembly 335 by being driven by a translation trolley 3. The material throwing belt 12 can be rotated left and right along the track by a worm gear reducer 312. The material throwing belt 12 on the inclined frame 112 can be inclined by a lifting mechanism 15, so that the material can be thrown and unloaded within a certain height range and within a certain width range to the left and right of the center of the railway line.

[0054] The material cart of the present invention, except for the railway flatbed transport car 4 (such as NX70 or NX70A type), the remaining devices are collectively referred to as bulk material conveying equipment. The bulk material conveying equipment is detachably connected to the railway flatbed transport car 4. When it needs to travel on the rails, the bulk material conveying equipment is installed on the railway flatbed transport car 4. When it needs to be transported, the bulk material conveying equipment can be placed on a freight car for transportation.
