Description

Technical Field

[0001] The invention relates to the field of track slag recovery, and in particular to a railway track bed slag recovery device. Background Art

[0002] With the development of high-speed railways, the planning of train routes is mostly designed with straight lines instead of curved lines, which shortens the time and space distance between two points. In this development process, some of the original railway routes are continued to be used by ordinary trains, but some railway routes are abandoned and cannot be used, and the large amount of slag accumulated on the bed cannot be reused.

[0003] If the abandoned railway is dismantled and the farmland is restored, the available land area in my country will be effectively increased. The large amount of slag on the ballast bed can be recycled and used for other infrastructure, which can increase the secondary utilization of slag. During the railway dismantling process, the rails and sleepers are relatively easy to remove, but the slag on the ballast bed is relatively scattered and not easy to be recycled.

[0004] In the prior art, the slag on the railway ballast is mainly recovered manually. Since the amount of slag on the railway ballast is large, a large amount of manpower is required, and the slag compacted by the train is not easy to be dug up, which increases the labor intensity of the staff. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide a railway ballast slag recovery device, in which a bucket and a conveying device are installed in front of a crawler vehicle. When the crawler vehicle moves forward, the bucket scoops up the slag on the railway ballast and transmits it to the crawler vehicle's carriage through the conveying device. The spiral blades then transfer the slag in the carriage to other trucks for transportation, thereby realizing the recovery of railway ballast slag.

[0006] In order to achieve the above-mentioned object, a railway ballast slag recovery device provided by the present invention is implemented as follows:

[0007] A railway ballast recovery device comprises a crawler vehicle, a first conveying device, a bucket, a second conveying device, a rotating table, a support frame, a discharge port, an annular bucket and spiral blades. The bucket is installed in front of the crawler vehicle and is used to scoop up ballast on the railway ballast. The first conveying device is installed in the bucket and is used to transport the ballast scooped up by the bucket. The second conveying device is installed on the side of the crawler vehicle and is used to transport the ballast on the first conveying device to the carriage of the crawler vehicle. The rotating table is installed in the carriage of the crawler vehicle, the spiral blades are installed on the rotating table, the annular bucket is installed above the rotating table and is lower than the top of the spiral blades. The discharge port is connected with the annular bucket. The support frame is installed on the carriage of the crawler vehicle and is used to support the annular bucket. The spiral blades are driven to rotate by the rotating table. The ballast in the carriage is transported to the annular bucket as the spiral blades rotate, and is transported to other trucks from the discharge port next to the annular bucket, and then transported to a designated storage point by the other trucks.

[0008] The first conveying device of the present invention includes a first roller, a transmission chain, a first rotating motor, a first gear, a rotating shaft, and a second gear. The first roller and the first rotating motor are installed at both ends of the bucket. The rotating shaft is connected to the rotating shaft of the first rotating motor. Two identical first gears are installed on the rotating shaft. Two identical second gears are installed at both ends of the first roller, and two identical transmission chains are installed between the two first gears and the second gears. The rotating shaft is driven by the first rotating motor to rotate, and then the two first gears are driven. The first gear is driven by the transmission chain, so that the transmission chain transports the slag scooped up by the bucket.

[0009] The two transmission chains of the present invention are provided with steel bars with equal spacing, the slag shoveled in by the bucket directly enters the steel bars, and the transmission chain drives the steel bars to rotate, so as to achieve the effect of transporting the slag.

[0010] A bearing is arranged between the second gear and the first roller of the present invention, and the second gear rotates on the bearing, thereby assisting the first rotating motor to drive the transmission chain to transmit the slag.

[0011] The second conveying device of the present invention comprises a second roller, a third roller, a fourth roller, a conveyor belt, a first synchronous pulley, a belt, a second synchronous pulley, and a second rotating motor. The second roller, the third roller, the fourth roller, and the second rotating motor are installed on the side of the crawler vehicle compartment, and the second roller, the third roller, and the fourth roller are installed at equal intervals. The conveyor belt is installed on the second roller, the third roller, and the fourth roller. The first synchronous pulley is installed at one end of the fourth roller. The second synchronous pulley is installed on the rotating shaft of the second rotating motor. A belt connection is provided between the first synchronous pulley and the second synchronous pulley. The second rotating motor drives the second synchronous pulley to rotate. The second synchronous pulley transmits the power to the first synchronous pulley through the belt. The first synchronous pulley drives the fourth roller to rotate, and then drives the conveyor belt to rotate, so as to achieve the effect of transporting slag in the first conveying device.

[0012] Baffles are also provided at both ends of the conveyor belt of the present invention to prevent the slag from falling when the conveyor belt is transporting slag.

[0013] The rotating table of the present invention includes a three-phase AC motor, a reduction gearbox, and a concave groove. The concave groove is installed in the carriage of the crawler vehicle and is used to load the slag transported by the second conveying device. The three-phase AC motor is installed below the concave groove. The rotating shaft of the three-phase AC motor is connected to the reduction gearbox. The output shaft of the reduction gearbox is connected to the bottom of the spiral blade. The three-phase AC motor drives the reduction gearbox, and the spiral blade is driven by the reduction gearbox to rotate, thereby rotating the slag in the concave groove into the annular bucket along with the spiral blade, and then transported from the discharge port to the slag transport vehicle. The reduction gearbox reduces the rotation speed of the three-phase AC motor and increases the output torque, thereby improving the transmission efficiency of the spiral blade.

[0014] The present invention provides a scheme for recycling slag on the railway ballast bed as follows: first, a worker removes the rails and sleepers, and then a crawler vehicle pushes a bucket forward to scoop up the slag on the ballast bed, and transmits it to the lower end of a second conveyor via a first conveyor device; the second conveyor device transmits the slag transmitted by the first conveyor device to a concave groove installed in a carriage of the crawler vehicle; then a three-phase AC motor drives a spiral blade to rotate and transport the slag to an annular bucket, thus completing the transportation of the slag; then the slag slides from a discharge port next to the annular bucket into a slag transport vehicle, and the slag transport vehicle transports the recovered slag to a designated location for storage.

[0015] Since the present invention adopts a structure in which a crawler vehicle drives a bucket to scoop up the slag from the railway track bed, and the slag is transferred to a slag transport vehicle through a first conveying device, a second conveying device, a spiral blade, etc., the following beneficial effects can be obtained:

[0016] The present invention transfers the slag to a transport vehicle through three transmissions for transportation, and the retained slag can be recycled for a second time to reduce waste. The cultivated land area can also be expanded to allow more land to be utilized. Secondly, in the slag recycling process, there is no need for manual shoveling of slag, which reduces the labor intensity of the staff. BRIEF DESCRIPTION OF THE DRAWINGS

The slag in the carriage is transported to the annular bucket 8 as the spiral blade 9 rotates, and is transported to other trucks from the discharge port 7 next to the annular bucket 8, and then transported to the designated storage point by other trucks, thus completing the recovery of the railway track bed slag. The crawler vehicle 1 and the truck transporting the slag need to maintain the same speed and a certain distance between the vehicles to prevent the crawler vehicle 1 from colliding with the truck transporting the slag and to prevent the slag output from the discharge port 7 from not being transported to the truck.

[0030] like Figure 2As shown, the first conveying device 2 includes a first roller 10, a transmission chain 11, a first rotating motor 12, a first gear 13, a rotating shaft 14, and a second gear 15. The first roller 10 and the first rotating motor 12 are installed at both ends of the bucket 3. The rotating shaft 14 is connected to the rotating shaft of the first rotating motor 12. Two identical first gears 13 are installed on the rotating shaft 14. Two identical second gears 15 are installed at both ends of the first roller 10, and two identical transmission chains 11 are installed between the two first gears 13 and the second gear 15. The rotating shaft 14 is driven by the first rotating motor 12 to rotate, and then the two first gears 13 are driven. The first gear 13 is driven by the transmission chain 11, so that the transmission chain 11 transports the slag shoveled by the bucket 3. The second gear 15 is installed on the first roller 10 mainly to assist the first rotating motor 12 to drive the transmission bar to rotate. The transmission chain 11 is close to the front end of the bucket 3, so that the shoveled slag can directly enter the first conveying device 2 for transmission.

[0031] like Figure 3 As shown, the two transmission chains 11 are provided with equally spaced steel bars 16. The slag shoveled in by the bucket 3 directly enters the steel bars 16, and the transmission chain 11 drives the steel bars 16 to rotate, thereby achieving the effect of transporting the slag.

The first synchronous pulley 22 is installed at one end of the fourth roller 20, and the second synchronous pulley 24 is installed on the rotating shaft of the second rotating motor 25. A belt 23 is provided between the first synchronous pulley 22 and the second synchronous pulley 24, and the second rotating motor 25 drives the second synchronous pulley 24 to rotate. The second synchronous pulley 24 transmits to the first synchronous pulley 22 through the belt 23. The first synchronous pulley 22 drives the fourth roller 20 to rotate, and then drives the conveyor belt 21 to rotate, so as to achieve the effect of transporting the slag in the first conveying device 2. The lower end of the conveyor belt 21 is close to the first conveyor device 2 , the first conveyor device 2 conveys the slag to the left, and the second conveyor device 4 conveys the slag upward, thereby transporting the slag on the railway bed to the carriage of the crawler vehicle 1 .

[0035] Baffles 29 are also provided at both ends of the conveyor belt 21 to prevent the conveyor belt 21 from falling when conveying slag.

[0036] like Figure 6 As shown, the rotating table 5 includes a three-phase AC motor 26, a reduction box 27, and a concave groove 28. The concave groove 28 is installed in the carriage of the crawler vehicle 1 and is used to load the slag transported by the second conveying device 4.

The output shaft of the reduction box 27 is connected to the bottom of the spiral blade 9. The reduction box 27 is driven by the three-phase AC motor 26, and the spiral blade 9 is driven by the reduction box 27 to rotate, thereby rotating the slag in the concave groove 28 along with the spiral blade 9 into the annular bucket 8, and then transported from the discharge port 7 to the slag transport vehicle. The reduction box 27 reduces the rotation speed of the three-phase AC motor 26 and increases the output torque, thereby improving the transmission efficiency of the spiral blade 9.

[0037] like Figure 7As shown, the recycling scheme for the railway ballast is as follows: the staff first removes the rails and sleepers, and then the crawler vehicle 1 pushes the bucket 3 forward to shovel the ballast on the ballast bed, and transmits it to the lower end of the second transmission device 4 through the first transmission device 2. The second transmission device 4 transmits the ballast transmitted by the first transmission device 2 to the concave groove 28 installed in the carriage of the crawler vehicle 1, and then the three-phase AC motor 26 drives the spiral blade 9 to rotate and transport the ballast to the annular bucket 8, that is, the transportation of the ballast is completed, and then the ballast slides from the discharge port 7 next to the annular bucket 8 into the ballast transport vehicle, and the ballast transport vehicle transports the recovered ballast to a designated location for storage. The stored ballast can be used for road hardening, roadbed backfilling, etc., to achieve secondary utilization of the railway ballast.

[0038] The working principle and working process of the present invention are as follows:

[0039] The crawler vehicle 1 pushes the bucket 3 forward to scoop up the slag on the roadbed, and transmits it to the lower end of the second transmission device 4 through the first transmission device 2. The second transmission device 4 transmits the slag transmitted by the first transmission device 2 to the concave groove 28 installed in the carriage of the crawler vehicle 1, and then the three-phase AC motor 26 drives the spiral blade 9 to rotate and transport the slag to the annular bucket 8. Then the slag slides from the discharge port 7 next to the annular bucket 8 into the slag transport vehicle, and the slag transport vehicle transports the recovered slag to the designated location for storage.
