Description

Technical Field

[0001] The invention relates to the technical field of track maintenance, in particular to an overhaul train with an electrically controlled flip-over sleeper centering mechanism. Background Art

[0002] The overhaul train is a large-scale track maintenance machinery and equipment that integrates mechanical, electrical, hydraulic and pneumatic functions. It is characterized by good operating quality, high efficiency, and fully automated assembly line operations such as collecting old sleepers, laying new sleepers and replacing rails. It can completely replace the heavy physical labor of traditional railway overhaul and is the most widely used and advanced large-scale track maintenance machinery for comprehensive railway overhaul on the market.

[0003] However, when the current overhaul train is operating in a non-linear manner, due to the influence of various factors, the old sleepers will shift, causing the recovery and transportation process to interfere with its body frame, causing the sleepers to tilt and resulting in downtime. At the same time, the current recovery operation has a complex structure and the recovery efficiency is not high enough. Summary of the invention

[0004] The technical problem to be solved by the present invention is that the current overhaul train will cause the old sleepers to deviate and interfere with its body frame when operating in a non-linear manner. At the same time, the structure of the recovery operation is complex and the recovery efficiency is not high enough.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an overhaul train with an electrically controlled flip-type pillow collection and centering mechanism, comprising a main frame, an electrically controlled flip conveyor belt being movably mounted on the upper surface of the main frame, downwardly bent lateral assembly frames being provided on both side walls of the main frame, lateral driving wheels and lateral adjustment wheels being movably mounted on the outer side of the lateral assembly frames, and an electrically controlled correction and centering mechanism being movably mounted on the inner side of the lateral adjustment wheel.

[0006] The upper surface of the main frame is provided with lateral assembly frames bent upwards on both sides of the electrically controlled turnover conveyor belt.

[0007] The electrically controlled flip conveyor belt comprises a flip frame movably connected to a lateral assembly frame at one side, an electric conveyor belt movably installed inside the flip frame, and a lateral support rod for controlling the flip frame.

[0008] The lateral assembly frame has an outwardly protruding lateral assembly ring at the lateral adjustment wheel assembly end outside, a longitudinal assembly bracket is welded and fixed on the outer surface of the lateral assembly ring, and a lateral support wheel is movably assembled on the longitudinal assembly bracket.

[0009] The electrically controlled correction and centering mechanism includes a lateral adjustment guide rail fixed on the inner wall of the lateral adjustment wheel, an electrically controlled screw rod movably installed inside the lateral adjustment guide rail, an internal thread adjustment frame threadedly sleeved on the electrically controlled screw rod, an internally-installed adjustment screw rod movably installed inside the internal thread adjustment frame, a first internally-threaded control seat threadedly sleeved on the internally-installed adjustment screw rod, a second internally-threaded control seat, a movable connection frame and a lateral extrusion disk.

[0010] An arc-shaped transition groove matching with the electric control screw rod is formed on one side of the first internal thread control seat and the second internal thread control seat, and lateral flip assembly grooves for movable assembly and movable connection frames are formed on both sides of the first internal thread control seat and the second internal thread control seat.

[0011] The movable connection frame includes a first flip extrusion frame and a second flip extrusion frame which are movably assembled through a central connecting shaft. The outer connecting end of the first flip extrusion frame is sleeved in a lateral flip assembly groove and movably assembled with a first internal thread control seat. The outer connecting end of the second flip extrusion frame is sleeved in a lateral flip assembly groove and movably assembled with a second internal thread control seat.

[0012] A lower optical recognition and positioning module for controlling an electrically controlled correction centering mechanism is fixedly mounted on the lower surface of the main frame.

[0013] An embedded adjusting motor for controlling a lateral adjusting wheel is fixedly mounted inside the lateral mounting ring.

[0014] The inner side of the lateral extrusion disk is equipped with electrically controlled turning limit claws all around.

[0015] The beneficial effects of the present invention are: (1) The overhaul train with an electrically controlled flip-type pillow collection and centering mechanism of the present invention can be adjusted at multiple angles as needed to facilitate recovery and transportation by movably assembling an electrically controlled flip conveyor belt on the upper surface of the main frame; (2) By movably assembling lateral driving wheels and lateral adjusting wheels on the outer sides of the lateral assembly frames on both sides of the main frame, not only can the entire main frame be supported and driven, but the sleepers can also be clamped, recovered, lifted and separated as driven by the lateral adjusting wheels; (3) By controlling the electronically controlled rotation to control the circular motion of the electronically controlled correction centering mechanism, the continuity of sleeper recovery can be improved and the recovery efficiency can be increased; (4) The electronically controlled correction centering mechanism is controlled by the lower optical recognition and positioning module on the lower surface of the main frame. It can not only detect and locate according to the height of the sleepers, but also greatly facilitate the control of the electronically controlled correction centering mechanism and improve the control accuracy. (5) The use of optical automatic positioning and automatic lifting separation greatly facilitates control; (6) By providing a lateral assembly ring protruding outward on the outside of the lateral assembly frame, and movably assembling a lateral support wheel on the outside of the lateral assembly ring through a longitudinal assembly bracket, the external protection and stability of the lateral adjustment wheel can be improved, and the assembly is convenient; (7) The electric-controlled correction and centering mechanisms on both sides are used to clamp and limit the two sides of the sleepers. Through the design of clamping first, lifting, and then flipping, the position of the sleepers can be corrected while clamping to avoid recovery interference. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] Figure 1 , Figure 2 and Figure 3 The overhaul train shown in the figure has an electrically controlled flip-type pillow collection and centering mechanism, comprising a main frame 1, an electrically controlled flip conveyor belt 2 is movably mounted on the upper surface of the main frame 1, downwardly bent lateral assembly frames 3 are provided on both side walls of the main frame 1, lateral driving wheels 4 and lateral adjustment wheels 5 are movably mounted on the outer side of the lateral assembly frames 3, and an electrically controlled correction and centering mechanism 6 is movably mounted on the inner side of the lateral adjustment wheel 5.

[0023] Working principle: the main frame 1 is transported along the track through the lateral driving wheel 4, and then the lateral adjusting wheel 5 is rotated and adjusted according to the position of the sleeper to be recovered, and then the sleeper is clamped and fixed from both sides through the electrically controlled correction and centering mechanism 6, and then the sleeper is lifted, and then turned outward from the bottom by using the lateral adjusting wheel 5, and then turned and transferred to the electrically controlled turning conveyor belt 2, and then the sleeper is separated onto the electrically controlled turning conveyor belt 2, and then the electrically controlled turning conveyor belt 2 is transported outward.

[0024] In order to cooperate with the assembly supports on both sides, the upper surface of the main frame 1 is provided with upwardly bent lateral assembly frames 7 on both sides of the electric-controlled flip conveyor belt 2 .

[0025] In order to cooperate with angle adjustment and transportation, the electrically controlled flip conveyor belt 2 includes a flip frame 21 movably connected to the lateral assembly frame 7 on one side, an electric conveyor belt 22 movably installed inside the flip frame 21 and a lateral support rod 23 for controlling the flip frame 21.

[0026] The lateral support rod 23 controls the turning adjustment of the turning frame 21 through telescopic adjustment, changes the angle of the turning frame 21, and then adjusts the transportation of the sleepers through the electric conveyor belt 22.

[0027] In order to cooperate with lateral assembly and adjustment, the outside of the lateral assembly frame 7 is located at the assembly end of the lateral adjustment wheel 5 and has an outwardly protruding lateral assembly ring 8. A longitudinal assembly bracket 9 is welded and fixed on the outer surface of the lateral assembly ring 8, and a lateral support wheel 10 is movably mounted on the longitudinal assembly bracket 9.

[0028] The bottom support and drive are provided by lateral drive wheels 4 and lateral support wheels 10 .

[0029] In order to cooperate with the electronically controlled adjustment of height and gap, the electronically controlled correction and centering mechanism 6 includes a lateral adjustment guide rail 61 fixed on the inner wall of the lateral adjustment wheel 5, an electronically controlled screw rod 62 movably installed inside the lateral adjustment guide rail 61, an internally threaded adjustment frame 63 threadedly sleeved on the electronically controlled screw rod 62, an internally threaded adjustment frame 63 movably installed inside the internally threaded adjustment frame 63, a first internally threaded control seat 65 threadedly sleeved on the internally threaded control seat 66, a movable connecting frame 67 and a lateral extrusion disk 68.

[0030] The electric control screw rod 62 controls the internal thread adjustment frame 63 to be raised and lowered along the lateral adjustment guide rail 61 by rotating, and the built-in adjustment screw rod 64 adjusts the gap between the first internal thread control seat 65 and the second internal thread control seat 66 by rotating, and the first internal thread control seat 65 and the second internal thread control seat 66 are adjusted in reverse, and then the movable connection frame 67 is squeezed to squeeze the lateral extrusion disk 68 inside and outside, and the lateral extrusion disk 68 is squeezed and clamped on both sides of the sleeper, and then the position of the sleeper is corrected, and then the sleeper is driven to rotate counterclockwise by the lateral adjustment wheel 5, and then the sleeper is flipped onto the main frame 1, and then flipped onto the electric control flip conveyor belt 2, and then the sleeper is transported and recycled to the recycling equipment by the electric control flip conveyor belt 2.

[0031] In order to facilitate assembly, an arc transition groove 11 that cooperates with the electric control screw 62 is opened on one side of the first internal thread control seat 65 and the second internal thread control seat 66, and lateral flip assembly grooves 12 for movable assembly and movable connection frames 67 are opened on both sides of the first internal thread control seat 65 and the second internal thread control seat 66.

[0032] In order to cooperate with the flip adjustment, the movable connecting frame 67 includes a first flip extrusion frame 671 and a second flip extrusion frame 672 which are movably assembled through a central connecting shaft. The outer connecting end of the first flip extrusion frame 671 is sleeved inside the lateral flip assembly groove 12 and movably assembled with the first internal thread control seat 65. The outer connecting end of the second flip extrusion frame 672 is sleeved inside the lateral flip assembly groove 12 and movably assembled with the second internal thread control seat 66.

[0033] The first internal thread control seat 65 and the second internal thread control seat 66 squeeze or pull the first flip extrusion frame 671 and the second flip extrusion frame 672 by translation, so as to adjust the gap between the lateral extrusion disk 68 and the sleeper, thereby clamping and correcting the position of the sleeper.

[0034] In order to cooperate with infrared optical positioning, a lower optical recognition and positioning module 13 for controlling the electronically controlled correction centering mechanism 6 is fixedly mounted on the lower surface of the main frame 1 .

[0035] When the main frame 1 moves, the lower optical recognition and positioning module 13 performs optical detection downward, and locates the position of the sleeper by measuring the height between the ground and the sleeper, and automatically controls the rotation of the lateral adjustment wheel 5. At the same time, the height of the internal thread adjustment frame 63 is adjusted so that the lateral extrusion disk 68 is opposite to both sides of the sleeper, which is convenient for positioning control.

[0036] In order to cooperate with the rotation adjustment, an embedded adjustment motor 14 for controlling the lateral adjustment wheel 5 is fixedly mounted inside the lateral mounting ring 8 .

[0037] The embedded adjusting motor 14 meshes with the annular tooth groove on the inner arc surface of the lateral extrusion disk 68 through the adjusting gear at the output end, and then the embedded adjusting motor 14 can drive the lateral adjusting wheel 5 to start rotating and adjusting.

[0038] In order to cooperate with the lateral clamping and limiting, the inner side of the lateral extrusion disk 68 is equipped with electrically controlled flip limiting claws 15 around it.

[0039] The electrically controlled flip limit claw 15 comprises a flip limit claw movably mounted on the outside of the lateral extrusion disc 68 and an extrusion support rod movably mounted on the inner side of the lateral extrusion disc 68. When the lateral extrusion disc 68 squeezes the sleeper from both sides, and then is lifted by the lateral extrusion disc 68, it is separated from the ground, and then the extrusion support rod is extended to control the flip limit claw to flip and limit to the outside of the sleeper, thereby improving the limiting capacity of both sides of the sleeper, thereby ensuring the stability when the sleeper is flipped and lifted.

[0040] Based on the above ideal embodiments of the present invention, the relevant staff can make various changes and modifications without departing from the technical concept of the present invention through the above description. The technical scope of the present invention is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
