Description

Technical Field

[0001] The invention belongs to the technical field of railway cleaning, and in particular relates to a liftable spiral drill railway ballast cleaning machine. Background Art

[0002] The ballast bed is a cushion layer of ballast (stone ballast) laid on the roadbed surface. Its main function is to support the sleepers, maintain their position, evenly transfer the pressure on the sleepers to the roadbed, drain rainwater, make the track elastic enough, and alleviate the impact of locomotives and vehicles on the rails.

[0003] The dirt brought into the track bed by wind and water, or the powder from the crushed ballast, often fills up the gaps in the track bed, forming an impermeable layer on the track bed, which leads to poor drainage and eventually causes the track bed to become compacted, with reduced elasticity and poor shock absorption, thus affecting driving safety. Therefore, railway workers need to regularly replace the ballast under the track.

[0004] At present, there are two main ways of cleaning and screening railways in my country. One is to use large railway cleaning machines in cooperation with railway workers to carry out cleaning and screening operations. The other is manual cleaning and screening. Although large railway cleaning and screening machines have high ballast cleaning efficiency and strong mobility, they are expensive and have a low penetration rate. The current difficulty of manual ballast cleaning operations is that it is difficult to clean the ballast under the sleepers using existing equipment (shovels, hoes), especially in the northwest region. Due to the serious compaction of ballast under the railway sleepers, the ballast cleaning operation is labor-intensive and consumes a lot of manpower.

[0005] Chinese patent publication number CN201785685U discloses a full-section excavation and screening machine. It can clean the ballast under the main line and turnout sleepers. When cleaning the ballast under the turnout, the bottom beam needs to be widened, and the ballast under the composite turnout sleeper cannot be cleaned. Chinese patent publication number CN108930204A discloses a railway ballast screening machine. Although it is not necessary to widen the bottom beam when cleaning the ballast under the turnout, it is also impossible to clean the ballast under the composite turnout sleeper, and manual operation is inconvenient.

[0006] In summary, the existing railway ballast cleaning machine has a small scope of application. Summary of the invention

DETAILED DESCRIPTION

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0033] like Figure 1 As shown, there are two rails 7, each of which extends longitudinally. The two rails 7 are arranged at intervals in the transverse direction and are supported on a plurality of sleepers 6. Each sleeper 6 extends transversely and a plurality of sleepers 6 are distributed on the ballast bed at intervals in the longitudinal direction.

[0034] This embodiment discloses a liftable auger railway ballast cleaning machine, which comprises a traveling device 1, a lifting device 2, a rotation limiting device 3, a horizontal moving device 4, and a ballast cleaning device 5.

[0035] like Figure 1 and Figure 3 As shown, the running device 1 includes wheels 11, wheel holders 12, positioning bolts 13, and a frame 14. The frame 14 is a horizontal plate structure. Four wheel holders 12 are installed on the bottom surface of the frame 14. The four wheels 11 are respectively installed on the wheel holders 12 through positioning bolts 13. Two wheels 11 correspond to one rail 7. The wheels 11 move longitudinally along the rail 7 to drive the entire liftable spiral drilling railway ballast cleaning machine to move longitudinally.

[0036] Continue as Figure 1and Figure 3 As shown, the horizontal moving device 4 includes a horizontal moving plate 41 , a slide rail 42 , a slide block 43 , a limit block 44 , a shock absorber 45 , and a protection frame 46 .

[0037] The horizontal moving plate 41 is arranged above the frame 14 and can be laterally moved on the frame 14, thereby driving the lifting device 2, the rotation limiting device 3, and the ballast cleaning device 5 to move laterally. Specifically, two transverse slide rails 42 are arranged on the top surface of the frame 14, and limit blocks 44 are arranged at both ends of each slide rail 42. The limit blocks 44 are used to limit the transverse movement of the horizontal moving plate 41 to prevent the horizontal moving plate 41 from detaching from the slide rails 42. The bottom surface of the horizontal moving plate 41 is connected with a slider 43, which moves laterally on the slide rails 42 through the slider 43, thereby realizing the transverse movement of the horizontal moving plate 41.

[0038] The top surface of the horizontal moving plate 41 is also connected to a protection frame 46 , and the lifting device 2 and the rotation limiting device 3 are partially located in the space surrounded by the protection frame 46 .

[0039] like Figure 3 As shown, the shock absorber 45 is fixed to the top surface of the horizontal moving plate 41 by bolts. The shock absorber 45 is used to reduce the vibration generated by the lifting device 2 during the ballast removal process. Specifically, when the lifting plate 221 of the lifting device 2 of this embodiment descends to the lowest point, it contacts the shock absorber 45, and the shock absorber 45 supports and reduces vibration of the lifting plate 221.

[0040] like Figure 1-Figure 4 As shown, the lifting device 2 of this embodiment includes a worm gear lift 21, a lifting platform 22, a coupling 23, a two-way commutator 24, a three-way commutator 25, a three-phase asynchronous motor 26, a linear bearing 27, and a linear cylindrical guide rail 28. The lifting device 2 is used to drive the rotation limit device 3 and the ballast removal device 5 to rise and fall.

[0041] The worm gear elevator 21, coupling 1 23, bidirectional commutator 24, three-way commutator 25, and three-phase asynchronous motor 26 of this embodiment are installed on the top surface of the horizontal moving plate 41. The lifting platform 22 includes a lifting plate 221 with a certain thickness. The lifting plate 221 is located above the horizontal moving plate 41. The up and down movement of the lifting plate 221 drives the rotation limit device 3 and the ballast removal device 5 to rise and fall.

[0042] Specifically, the number of the three-phase asynchronous motor 26 is one. The number of the three-way commutator 25 is one. The number of the worm gear elevator 21 and the number of the two-way commutator 24 are both two. The worm gear elevator 21 includes an elevator 211, a screw nut 212, and a screw 213.

[0043] The bidirectional commutator 24 of this embodiment is fixed to the top surface of the horizontal moving plate 41 by bolts. The bidirectional commutator 24 is L-shaped. The three-way commutator 25 is T-shaped. The input end of the bidirectional commutator 24 is connected to an output end of the three-way commutator 25 through a coupling 23. The output end of the bidirectional commutator 24 is connected to the input end of the elevator 211 through a coupling 23. The input end of the three-way commutator 25 is connected to the output end of the three-phase asynchronous motor 26.

[0044] The three-phase asynchronous motor 26 drives the worms of the two elevators 211 to rotate respectively through the three-way commutator 25, two couplings 23 and two bidirectional commutators 24. The horizontal worm of the elevator 211 drives the turbine, and the turbine drives the screw 213 to rotate. Figure 8 As shown, the screw nut 212 is fixed on the lifting plate 221. The screw nut 212 moves up and down in a spiral manner to drive the lifting plate 221 to move up and down.

[0045] In order to improve the stability of the lifting plate 221 moving up and down, the present embodiment is provided with a linear bearing 27 and a linear cylindrical guide rail 28. Specifically, Figure 1 and Figure 8 As shown, two symmetrical vertical linear cylindrical guide rails 28 are installed on the horizontal moving plate 41. Two symmetrical linear bearings 27 are installed on the lifting plate 221. The linear bearings 27 cooperate with the linear cylindrical guide rails 28 to guide the lifting and lowering of the lifting plate 221. The top end of the linear cylindrical guide rail 28 of this embodiment is connected to the protection frame 46 to improve the stability of the linear cylindrical guide rail 28.

[0046] like Figure 1 As shown, the protection frame 46 is provided with a through hole for the motor 58 of the ballast cleaning device 5 to pass through during the lifting process.

[0047] The rotation limiting device 3 of this embodiment is used to drive the ballast cleaning device 5 to rotate a preset angle. The rotation limiting device 3 of this embodiment is rotated by manual drive.

[0048] like Figure 1 , Figure 7 and Figure 8 As shown, the rotation limiting device 3 of this embodiment includes a cage-type fixed support frame 31, a slewing support 32, a slewing support upper plate 33, a cage-type rotation limiting seat 34, a limiting mechanism 35, and a transition sleeve 37.

[0049] The lifting plate 221 is provided with a mounting hole. The top of the cage-type fixed support frame 31 has a flange 311. The cage-type fixed support frame 31 is inserted into the mounting hole of the lifting plate 221 and the flange 311 of the cage-type fixed support frame 31 is limited by the mounting hole of the lifting plate 221, so that the cage-type fixed support frame 31 is hung on the lifting plate 221, and the flange 311 of the cage-type fixed support frame 31 is fixed on the lifting plate 221 through a connecting piece.

[0050] The main body of the cage-type fixed support frame 31 of this embodiment is located below the lifting plate 221. The advantage of this arrangement is that, compared with installing the cage-type fixed support frame 31 above the lifting plate 221, the main shaft 56 of the ballast cleaning device 5 can be closer to the surface to be cleaned, thereby saving the length of the main shaft 56. In addition, the cage-type fixed support frame 31 of this embodiment is a cage-type structure, which is light in weight and saves costs.

[0051] like Figure 7 As shown, the cage type rotation limit seat 34 includes an upper ring body 341 and a lower ring body 342. The upper ring body 341 and the lower ring body 342 are arranged at intervals, and the upper ring body 341 and the lower ring body 342 are connected by at least two vertical connecting rods 343. The at least two vertical connecting rods 343 are distributed at intervals in the circumferential direction.

[0052] The top surface of the upper ring body 341 is provided with at least two limiting grooves 345 distributed along the circumferential direction. As a preferred solution, the limiting grooves 345 of this embodiment are rectangular grooves. In other embodiments, the limiting grooves 345 can also be other polygonal structures. Figure 8 As shown, the limiting mechanism 35 includes a limiting rod 351 installed on the lifting plate 221, and the limiting rod 351 has a plug hole for inserting the limiting pin 352. The limiting groove 345 is used to be plugged and matched with the limiting pin 352. Specifically, the limiting pin 352 is an L-shaped structure, and the vertical part of the limiting pin 352 is inserted into the plug hole of the limiting rod 351 and a limiting groove 345 in sequence. The bottom end of the vertical part of the limiting pin 352 matches the shape of the limiting groove 345, and the end face is rectangular.

[0053] As a preferred solution, a circular groove 344 is further provided above the limiting groove 345. That is, the top surface of the upper ring body 341 is formed with a circular groove 344 and a limiting groove 345 in sequence from top to bottom. The circular groove 344 is connected to the limiting groove 345. The circular groove 344 can play a guiding role. The limiting groove 345 of this embodiment may penetrate the bottom surface of the upper ring body 341, or may not penetrate the bottom surface of the upper ring body 341.

[0054] like Figure 8As shown, the cage-type rotation limit seat 34 is inserted into the inner cavity of the cage-type fixed support frame 31, and the upper ring body 341 is limited by the flange 311. The cage-type rotation limit seat 34 of this embodiment is a rotating component. In order to reduce the resistance of the cage-type rotation limit seat 34 during the rotation process, a plurality of protrusions are provided on the top surface of the flange 311, and the upper surface of the protrusions cooperates with the bottom surface of the upper ring body 341. This makes it easy for operators to manually rotate the cage-type rotation limit seat 34.

[0055] Continue as Figure 8 As shown, a slewing support 32 is installed at the bottom of the inner cavity of the cage-type fixed support frame 31. The slewing support 32 includes an outer ring and an inner ring. The inner ring can rotate relative to the outer ring. The outer ring is fixed to the cage-type fixed support frame 31 by bolts.

[0056] The cage type rotation limit seat 34 is fixedly connected to the inner ring so as to be able to rotate. The motor 58 of the ballast cleaning device 5 is fixedly connected to the slewing support upper plate 33. Figure 6 As shown, the flange at the upper end of the transition sleeve 37 is connected to the inner ring of the slewing support 32 by bolts, so that it can rotate synchronously with the inner ring. The transition sleeve 37 extends downward to the commutator 55 of the ballast cleaning device 5. The transition sleeve 37 is sleeved on the main shaft 56 and the second coupling 57 of the ballast cleaning device 5. The main shaft 56 of the ballast cleaning device 5 is connected to the motor 58 of the ballast cleaning device 5 through the second coupling 57.

[0057] like Figure 1 and Figure 6 As shown, the ballast cleaning device 5 includes an auger head 1 51 , an auger head 2 52 , a rake tooth seat 53 , rake teeth 54 , a commutator 55 , a main shaft 56 , a coupling 2 57 , and a motor 58 .

[0058] The output shaft of the motor 58 is connected to the top of the main shaft 56 through the second coupling 57. The main shaft 56 extends vertically. The lower end of the main shaft 56 is connected to the input shaft of the commutator 55 through the second coupling 57.

[0059] Two mutually meshing bevel gears are arranged in the commutator 55, and the two mutually meshing bevel gears are respectively a driving bevel gear 553 and a driven bevel gear 554. The driving bevel gear 553 is connected to a vertically extending first output shaft 551, and the driven bevel gear 554 is connected to a horizontally extending second output shaft 552.

[0060] The first output shaft 551 is connected to the auger 1 51, and the rotation of the first output shaft 551 drives the auger 1 51 to rotate. The auger 1 51 of this embodiment extends vertically, and a plurality of rake tooth seats 53 are distributed on the surface of the auger 1 51, and each rake tooth seat 53 is installed with rake teeth 54.

[0061] The second output shaft 552 is connected to the auger bit 2 52, and the rotation of the second output shaft 552 drives the auger bit 2 52 to rotate. The auger bit 2 52 of this embodiment extends horizontally, and a plurality of rake tooth seats 53 are distributed on the surface of the auger bit 2 52, and each rake tooth seat 53 is installed with a rake tooth 54. The bottom end of the auger bit 1 51 of this embodiment is lower than the auger bit 2 52.

[0062] As a preferred solution, the rake teeth 54 of this embodiment extend along a spiral line to improve the cleaning effect.

[0063] like Figure 4 As shown, a through hole 141 extending in the transverse direction is provided on the vehicle frame 14. The main shaft 56 passes through the through hole 141 from top to bottom, and when the horizontal moving plate 41 moves transversely, the main shaft 56 moves transversely in the through hole 141. In general, the transverse movement of the horizontal moving plate 41 drives the entire ballast cleaning device 5 to move transversely.

[0064] The staff presses the forward switch of the three-phase asynchronous motor 26. The lifting plate 221 descends, driving the rotation limit device 3 and the ballast removal device 5 to descend to the specified position. The staff rotates the cage-type rotation limit seat 34 to a preset angle. The vertical portion of the limit pin 352 is inserted into the jack of the limit rod 351 and a limit slot 345 in sequence to position the preset angle. When the angle needs to be changed, the limit pin 352 is pulled out, and the vertical portion of the limit pin 352 is inserted into the jack of the limit rod 351 and another limit slot 345 in sequence again.

[0065] During operation, the auger 51 first contacts the ballast. The rake teeth 54 of the auger 51 break the hardened ballast between the sleepers. The staff slowly pushes the horizontal moving plate 41 along the direction of the sleepers 6, and the auger 51 moves horizontally to clean the remaining ballast between the sleepers.

[0066] After cleaning the ballast between the sleepers, the staff pulls out the limit pin 352, slowly rotates the cage-type rotating limit seat 34 to a preset angle, and then positions it. The spiral drill bit 2 52 contacts the ballast under the sleeper 6, and the rake teeth 54 of the spiral drill bit 2 52 clean the ballast under the sleeper 6. After the spiral drill bit 2 52 cleans the ballast under one sleeper 6, the staff pulls out the limit pin 352, slowly rotates the cage-type rotating limit seat 34 to the next preset angle, and then positions it. The spiral drill bit 2 52 cleans the ballast under the adjacent sleeper 6.

[0067] After the ballast between the sleepers and under the two sleepers 6 is cleaned, the limit pin 352 is pulled out, and the auger head 1 51 and the auger head 2 52 are rotated between the two sleepers 6. The reverse switch of the three-phase asynchronous motor 26 is pressed to raise the lifting device 2 to a certain height, so that the auger head 1 51 and the auger head 2 52 are lifted above the sleepers 6. Then the staff pushes the walking device 1 to walk along the rail 7, and prepares to clean the ballast between the sleepers of the next section and the ballast under the two sleepers 6.

[0068] The liftable spiral drill railway ballast cleaning machine of the present embodiment is a small railway ballast cleaning machine, and is convenient for workers to operate, with low labor intensity for workers.

[0069] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here.
