Description

Technical Field

[0001] The present invention belongs to the technical field of rail car rail shifting tools, and particularly relates to a rail shifter for a rail car used for cross-rail track switching. Background Art

[0002] A cross-rail, that is, a cross-intersecting rail, refers to the place where two rails intersect on a railway; the following is the development process of the cross-rail: the earliest cross-rail was a simple intersection where two rails crossed together, called a plane intersection; this structure was prone to friction and noise, which affected the driving speed and safety of trains; later, a stereoscopic intersection appeared, that is, one rail crossed above the other rail, forming a bridge structure; this design reduced the friction and noise at the intersection and improved the driving efficiency of trains; when a rail car travels on the rails and needs to switch the cross-rail, in the early stage, manual switching was required with an "F" wrench, which was laborious and time-consuming and had low efficiency; currently, a rail shifter is used to switch the rails, but when the rail car is traveling, since the wheels are not completely in contact with the rails, the rail car shakes, which in turn causes the rail shifter to rub against the side of the guide rail, reducing the service life of the rail shifter and increasing the work done by the rail car; therefore, improvement and treatment are needed according to the above problems. Summary of the Invention

DETAILED DESCRIPTION

[0031] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer, the present invention is further described in detail in conjunction with the embodiments and the accompanying drawings. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. The technical solutions of the present invention are described in detail below in conjunction with the embodiments and the accompanying drawings, but the scope of protection is not limited thereto.

[0032] like Figure 1 As shown in FIG. 12 , the present invention provides a track deflector for a rail vehicle for cross-track track changing, comprising a guide rail 1 and a rail vehicle 4, wherein the guide rail 1 comprises a transverse guide rail 1 and a longitudinal guide rail 1 which are vertically crossed, and a track changing mechanism is rotatably arranged at the connection between the transverse guide rail 1 and the longitudinal guide rail 1; the wheels 5 of the rail vehicle 4 travel on the guide rail 1, and a group of track deflection mechanisms are respectively arranged at the front and rear ends of the lower end face of the rail vehicle 4, and the track deflection mechanism comprises a width adjustment component, and a positioning block 10 is respectively arranged at the left and right ends of the width adjustment component, and a liftable positioning seat 17 is arranged at the lower end of the positioning block 10 through a lifting component, and a horizontally rotatable positioning plate 25 is arranged at the lower end of the positioning seat 17 through a rotating positioning component, and a track deflection component is respectively arranged at the lower end of each positioning plate 25.

[0033] The transverse guide rail 1 and the longitudinal guide rail 1 each include two parallel guide rails, and a set of track changing mechanisms are provided at the cross connection between the two transverse guide rails 1 and the two longitudinal guide rails 1. The track changing mechanism includes a fixed disk 2 and a track divider 3, wherein the fixed disk 2 is a horizontally arranged circular plate-like structure, and the fixed disk 2 is fixedly arranged on the ground; the track divider 3 includes a turntable and a rotating guide rail, wherein the turntable is a horizontally arranged circular plate-like structure, and the turntable is rotatably arranged at the upper end of the fixed disk 2, and the rotating guide rail is fixedly arranged at the upper end surface of the turntable. When the rotating guide rail is arranged along the front-to-back direction, the rotating guide rail is connected to the transverse guide rails 1 on the front and rear sides; when the turntable drives the rotating guide rail to rotate 90°, the rotating guide rail is connected to the longitudinal guide rails 1 on the left and right sides.

[0034] At the four corners of the lower end surface of the rail vehicle 4, a wheel 5 is rotatably arranged respectively. The two wheels 5 on the left travel on one of the guide rails 1, and the two wheels 5 on the right travel on the other guide rail 1.

[0035] The width adjustment assembly includes a connecting plate 6, a connecting rod 7, a circular plate 8, and a tension spring 9.

[0036] The connecting plate 6 is a horizontally arranged square plate-like structure, and the connecting plate 6 is fixedly arranged on the lower end surface of the rail vehicle 4. On the left and right side end surfaces of the connecting plate 6, there are respectively two front and rear insertion holes, and the insertion holes are horizontally arranged along the left and right directions; between the two front insertion holes and between the two rear insertion holes, they are both connected by an action hole, and the action hole is horizontally arranged along the left and right directions, and the inner diameter of the action hole is larger than the inner diameter of the insertion hole. Inside each insertion hole, a connecting rod 7 is slidably inserted. The inner end of the connecting rod 7 extends into the action hole, and the outer end of the connecting rod 7 extends out of the outside of the connecting plate 6. A circular plate 8 is fixedly arranged at the end of the connecting rod 7 extending into the action hole, and the outer cylindrical surface of the circular plate 8 is in sliding contact with the inner wall of the action hole. Inside the two action holes, a tension spring 9 is arranged, and the two ends of the tension spring 9 are respectively fixedly connected to the circular plates 8 on the left and right sides. The outer ends of the two connecting rods 7 on the left are fixedly arranged with the same positioning block 10, and the outer ends of the two connecting rods 7 on the right are fixedly arranged with the same positioning block 10.

[0037] When the width between the left and right positioning blocks 10 becomes larger, the two connecting rods 7 stretch the tension spring 9; when the width between the left and right positioning blocks 10 becomes smaller, the two connecting rods 7 compress the tension spring 9. The width between the two positioning blocks 10 is adjusted by the compression and stretching of the tension spring 9.

[0038] The lifting assembly includes a connecting cylinder 11, a screw rod 12, a hand wheel 16, a worm 14, and a worm gear 13.

[0039] The positioning seat 17 is a horizontally arranged plate-like structure and is disposed below the positioning block 10. At the lower end face of the positioning block 10, a connecting cylinder 11 is fixedly arranged. The connecting cylinder 11 is a cylindrical structure with an open lower end. A vertical screw rod 12 is slidably inserted into the connecting cylinder 11, and the lower end of the screw rod 12 is fixedly connected to the positioning seat 17. At the middle height of the inner wall of the connecting cylinder 11, an annular rotating groove is arranged, and a worm gear 13 is rotatably arranged in the rotating groove. The inner wall of the worm gear 13 is in threaded connection with the screw rod 12. At the middle height of the outer wall of the connecting cylinder 11, a hollow outer shell 15 is fixedly arranged, and the interior of the outer shell 15 is in communication with the rotating groove; a worm 14 is rotatably arranged inside the outer shell, and the worm 14 is in meshing engagement with the worm gear 13; one end of the worm 14 extends to the outside of the outer shell 15, and a hand wheel 16 is fixedly arranged at the extending end of the worm 14.

[0040] When the hand wheel 16 is rotated, the hand wheel 16 drives the worm 14 to rotate. Since the worm 14 is in meshing engagement with the worm gear 13, the worm gear 13 is driven to rotate. Since the worm gear 13 is in threaded connection with the screw rod 12, the screw rod 12 is driven to move up and down, and the screw rod 12 drives the positioning seat 17 to move up and down.

[0041] The rotation positioning assembly includes a supporting plate 18, an electric push rod 19, an adjusting cylinder 20, a torsion spring 22, a spline sleeve 23, a positioning ring 24, and a rotating rod 21.

[0042] The positioning plate 25 is a horizontally arranged square plate-like structure and is located below the positioning seat 17. At the lower end face of the positioning seat 17, a supporting plate 18 is fixedly arranged. The supporting plate 18 is a horizontally arranged circular plate-like structure. At the lower end face of the supporting plate 18, an adjusting cylinder 20 is fixedly arranged. The adjusting cylinder 20 is a circular cylindrical structure with an open lower end. A vertical rotating rod 21 is rotatably arranged inside the adjusting cylinder 20. A torsion spring 22 is arranged between the outer wall of the rotating rod 21 and the inner wall of the adjusting cylinder 20, and both ends of the torsion spring 22 are respectively connected to the inner wall of the adjusting cylinder 20 and the outer wall of the rotating rod 21. The positioning plate 25 is fixedly arranged at the lower end of the rotating rod 21. At the outer edge of the upper end face of the supporting plate 18, a circle of electric push rods 19 is fixedly arranged. The piston rods of the circle of electric push rods 19 vertically penetrate through the supporting plate 18; the ends of the piston rods of the circle of electric push rods 19 are fixedly provided with the same positioning ring 24. A spline groove is arranged on the inner side surface of the positioning ring 24, and the positioning ring 24 is sleeved outside the rotating rod 21. The positioning ring 24 is driven to move up and down by the telescopic movement of the piston rod of the electric push rod 19. A spline sleeve 23 is fixedly sleeved outside the rotating rod 21, and the spline sleeve 23 is located below the adjusting cylinder 20.

[0043] When the piston rod of the electric push rod 19 is in the contracted state, the positioning ring 24 is at the high point position. At this time, the positioning ring 24 meshes with the spline sleeve 23. Due to the limitation of the positioning ring 24, the spline sleeve 23 and the rotating rod 21 cannot rotate. When the piston rod of the electric push rod 19 is in the extended state, the positioning ring 24 is at the low point position. At this time, the positioning ring 24 is disengaged from the spline sleeve 23, and the rotating rod 21 can freely rotate inside the adjusting cylinder 20.

[0044] When the rotating rod 21 can rotate freely, due to the limitation of the torsion spring 22, the rotating rod 21 can only rotate a certain angle, and after the external force disappears, the rotating rod 21 returns to the set angle.

[0045] The shifting rail assembly includes a connecting seat 26, a shifting block 27, a bidirectional lead screw 28, a connecting nut 29, a first spring 30, a moving seat 31, a baffle 32, a second spring 33, and a pulley 34.

[0046] A connecting seat 26 is fixedly arranged on the lower end face of the positioning plate 25. The connecting seat 26 is a horizontally arranged cubic structure. At the middle height of the end faces of the left and right connecting seats 26 close to each other, a connecting groove is respectively arranged, and the connecting groove communicates with the front end face of the connecting seat 26. A shifting block 27 is respectively arranged inside the connecting groove of each connecting seat 26. The shifting block 27 is a horizontally arranged cubic structure. One end of the two shifting blocks 27 close to each other extends to the outside of the connecting groove, and the front ends of the two shifting blocks 27 both extend to the outside of the connecting groove. And the front ends of the side faces of the two shifting blocks 27 close to each other are both arranged as arc surfaces.

[0047] On the side wall of the connecting groove far from the other connecting seat 26, two front and rear connecting ports are respectively arranged. A bidirectional lead screw 28 is inserted into each connecting port. The inner end of the bidirectional lead screw 28 is screwed with the shifting block 27 inside the connecting groove. The outer end of the bidirectional lead screw 28 extends to the outside of the connecting seat 26, and a connecting nut 29 is screwed on the outer end of the bidirectional lead screw 28. A first spring 30 is sleeved on the outer side of the bidirectional lead screw 28. The two ends of the first spring 30 are respectively connected with the shifting block 27 and the inner wall of the connecting groove. Through the setting of the first spring 30, it is ensured that the shifting block 27 and the inner wall of the connecting groove maintain the maximum distance. When the shifting block 27 is subjected to an external force, the shifting block 27 retracts into the connecting groove, and the shifting block 27 compresses the first spring 30; when the external force acting on the shifting block 27 disappears, the shifting block 27 extends to the outside of the connecting groove again under the resilience of the first spring 30.

[0048] On the end faces of the two shifting blocks 27 close to each other, there are respectively two front and rear outer movable grooves. Inside each outer movable groove, there is an inner movable groove. The inner movable groove and the outer movable groove are connected by a communication hole. The axis of the communication hole is horizontally arranged along the left-right direction, and the inner diameter of the communication hole is smaller than the inner diameters of the inner movable groove and the outer movable groove. A sliding rod is slidably inserted into the communication hole. One end of the sliding rod extending into the inner movable groove is fixedly provided with a circular baffle 32, and one end of the sliding rod extending into the outer movable groove is fixedly provided with a moving seat 31. A second spring 33 is sleeved outside the sliding rod. The second spring 33 is located inside the outer movable groove, and both ends of the second spring 33 are connected to the inner side surface of the outer movable groove and the moving seat 31 respectively. A pulley 34 is rotatably provided at the outer end of the moving seat 31, and the pulley 34 extends outside the opening of the outer movable groove.

[0049] A method for using a rail shifter for a rail vehicle for cross-rail track changing provided by the present invention includes the following steps:

[0050] Step 1, first connect the wires of all electrical equipment and power on, then pull the connecting rods 7 inside the two side connection plates 6 outwards. At this time, the tension springs 9 are in a stretched state, and the positioning blocks 10 on the left and right sides move outwards, thereby controlling the overall movement of the parts connected to the lower ends of the positioning blocks 10 outwards, and further controlling the movement of the shifting blocks 27 on the left and right sides outwards, so that the pulleys 34 on the shifting blocks 27 abut against the side surface of the guide rail 1. Then rotate the handwheel 16, control the rotation of the worm 14 through the handwheel 16, drive the rotation of the worm wheel 13 through the meshing of the worm 14 and the worm wheel 13, and then connect the worm wheel 13 and the screw rod 12 by threads. When the worm wheel 13 rotates, control the lifting of the screw rod 12. When the screw rod 12 lifts, control the lifting of the lower shifting block 27. After moving the shifting block 27 to a suitable height on the side surface of the guide rail 1, stop rotating the handwheel 16, and lock the screw rod 12 through the worm wheel 13 and the worm 14.

[0051] Step 2, after the position of the shifting block 27 is determined, then start the rail vehicle 4, and the wheels 5 move on the guide rail 1. At this time, the pulley 34 abuts against the side surface of the guide rail 1 and slides. When the rail vehicle 4 moves to the intersection of the guide rail 1 and continues to move, the head of the shifting block 27 will hit the rotating guide rail on the rail splitter 3, thereby controlling the rotation of the rail splitter 3, so that the rotating guide rail is docked with the guide rail 1 in the advancing direction of the rail vehicle 4, and the rail vehicle 4 can pass smoothly.

[0052] Step 3: When the rail vehicle 4 moves, since the guide rail 1 and the wheels 5 are not in full contact, the rail vehicle 4 shakes, which in turn causes the toggle 27 to swing. When the toggle 27 swings, due to the resilience of the first spring 30, the toggle 27 moves towards the outside of the connecting groove of the connecting seat 26, and then the pulley 34 abuts against the side surface of the guide rail 1. Secondly, due to the resilience of the second spring 33, the pulley 34 moves towards the outside of the outer activity groove, so that the pulley 34 always stably abuts against the side surface of the guide rail 1.

[0053] Step 4: When the rail vehicle 4 moves onto the guide rail 1 with a curvature, start the electric push rod 19. Push the positioning ring 24 downward through the piston rod of the electric push rod 19. At this time, the positioning ring 24 is separated from the spline sleeve 23, so as to control the rotation of the rotating rod 21. When the pulley 34 moves with the rail vehicle 4 on the guide rail 1 with a curvature, the torsion spring 22 is used to control the adaptive deflection of the rotating rod 21, so as to control the adaptive deflection of the toggle 27, and then keep the pulley 34 abutted against the side surface of the guide rail 1. When traveling on the straight guide rail 1, start the electric push rod 19 to control the piston rod to retract, so as to control the positioning ring 24 to rise, and then engage with the spline sleeve 23, so as to lock the rotating rod 21 and make the rotating rod 21 stop rotating; when the transportation task of the rail vehicle 4 is completed, cut off the power supply of all electrical equipment.

[0054] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-restrictive.
