[0020] The width adjustment assembly includes a connecting plate 6 , a connecting rod 7 , a circular plate 8 , and a tension spring 9 .

[0021] The connecting plate 6 is a square plate-shaped structure arranged horizontally, and the connecting plate 6 is fixedly arranged on the lower end surface of the rail car 4. Two front and rear plug-in holes are respectively arranged on the left and right end surfaces of the connecting plate 6, and the plug-in holes are arranged horizontally along the left and right directions; the two plug-in holes on the front side and the two plug-in holes on the rear side are connected by an action hole, and the action hole is arranged horizontally along the left and right directions, and the inner diameter of the action hole is larger than the inner diameter of the plug-in hole. A connecting rod 7 is slidably inserted inside each plug-in hole, and the inner end of the connecting rod 7 extends into the inside of the action hole, and the outer end of the connecting rod 7 extends to the outside of the connecting plate 6.

[0023] The lifting assembly includes a connecting tube 11 , a screw rod 12 , a hand wheel 16 , a worm 14 , and a worm wheel 13 .

[0024] The positioning seat 17 is a horizontally arranged plate-like structure, and the positioning seat 17 is arranged below the positioning block 10. A connecting cylinder 11 is fixedly arranged at the lower end surface of the positioning block 10, and the connecting cylinder 11 is a cylindrical structure with an opening at the lower end. A vertical screw 12 is slidably inserted inside the connecting cylinder 11, and the lower end of the screw 12 is fixedly connected to the positioning seat 17. A circular rotating groove is arranged at the middle height of the inner wall of the connecting cylinder 11, and a worm wheel 13 is rotatably arranged inside the rotating groove, and the inner wall of the worm wheel 13 is threadedly connected to the screw 12. A hollow outer shell 15 is fixedly arranged at the middle height of the outer wall of the connecting cylinder 11, and the interior of the outer shell 15 is connected to the rotating groove; a worm 14 is rotatably arranged inside the outer side, and the worm 14 is meshed with the worm wheel 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 end of the worm 14 that extends out.

[0025] When the hand wheel 16 is rotated, the hand wheel 16 drives the worm 14 to rotate. Since the worm 14 is meshed with the worm wheel 13, the worm wheel 13 is driven to rotate. Since the worm wheel 13 is screwed with the screw 12, the screw 12 is driven to rise and fall. The screw 12 drives the positioning seat 17 to rise and fall.

[0026] The rotation positioning assembly includes a supporting plate 18 , an electric push rod 19 , an adjustment cylinder 20 , a torsion spring 22 , a spline sleeve 23 , a positioning ring 24 , and a rotating rod 21 .

[0027] The positioning plate 25 is a horizontally arranged square plate-like structure, and the positioning plate 25 is located below the positioning seat 17. A support plate 18 is fixedly arranged at the lower end surface of the positioning seat 17, and the support plate 18 is a horizontally arranged circular plate-like structure. An adjustment cylinder 20 is fixedly arranged at the lower end surface of the support plate 18, and the adjustment cylinder 20 is a circular cylinder-like structure with an opening at the lower end. A vertical rotating rod 21 is rotatably arranged inside the adjustment cylinder 20, and a torsion spring 22 is arranged between the outer wall of the rotating rod 21 and the inner wall of the adjustment cylinder 20, and the two ends of the torsion spring 22 are respectively connected to the inner wall of the adjustment 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. A circle of electric push rods 19 is fixedly arranged at the outer edge of the upper end surface of the support plate 18, and the piston rod of the electric push rod 19 vertically passes through the support plate 18 downward; the same positioning ring 24 is fixedly arranged at the end of the piston rod of a circle of electric push rods 19, and the inner side of the positioning ring 24 is provided with a spline groove. The positioning ring 24 is sleeved on the outer side of the rotating rod 21, and the positioning ring 24 is driven to rise and fall by the extension and contraction of the piston rod of the electric push rod 19. A spline sleeve 23 is fixedly sleeved on the outer side of the rotating rod 21, and the spline sleeve 23 is located below the adjustment cylinder 20.

[0028] When the piston rod of the electric push rod 19 is in a retracted state, the positioning ring 24 is at a high point, and the positioning ring 24 is meshed with the spline sleeve 23. Due to the restriction 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 an extended state, the positioning ring 24 is at a low point, and the positioning ring 24 is disengaged from the spline sleeve 23, and the rotating rod 21 can rotate freely inside the adjusting cylinder 20.

[0029] When the rotating rod 21 can rotate freely, due to the limitation of the torsion spring 22, the rotating rod 21 can only rotate to a certain angle, and after the external force disappears, the rotating rod 21 returns to the set angle.

[0030] The rail derailing assembly includes a connecting seat 26 , a derailing block 27 , a bidirectional screw rod 28 , a connecting nut 29 , a first spring 30 , a moving seat 31 , a baffle 32 , a second spring 33 , and a pulley 34 .

[0031] A connecting seat 26 is fixedly provided on the lower end surface of the positioning plate 25, and the connecting seat 26 is a horizontally arranged cubic structure. A connecting groove is respectively provided at the middle height of the end surface of the side where the two connecting seats 26 are close to each other, and the connecting groove is connected to the front end surface of the connecting seat 26. A shift block 27 is respectively provided inside the connecting groove of each connecting seat 26, and the shift block 27 is a horizontally arranged cubic structure, and the ends of the two shift blocks 27 close to each other extend to the outside of the connecting groove, and the front ends of the two shift blocks 27 both extend to the outside of the connecting groove. And the front ends of the end surfaces of the side where the two shift blocks 27 are close to each other are both set as arc surfaces.

[0032] Two front and rear connection ports are respectively arranged on the side wall of the connection groove away from the other connection seat 26, and a bidirectional screw rod 28 is inserted in each connection port. The inner end of the bidirectional screw rod 28 is screwed with the shift block 27 in the connection groove, and the outer end of the bidirectional screw rod 28 extends to the outside of the connection seat 26, and a connection nut 29 is screwed on the outer end of the bidirectional screw rod 28. A first spring 30 is sleeved on the outer side of the bidirectional screw rod 28, and the two ends of the first spring 30 are respectively connected to the shift block 27 and the inner wall of the connection groove. The arrangement of the first spring 30 ensures that the shift block 27 maintains the maximum distance from the inner wall of the connection groove. When the shift block 27 is subjected to external force, the shift block 27 retracts into the connection groove, and the shift block 27 compresses the first spring 30; when the external force on the shift block 27 disappears, the shift block 27 is extended to the outside of the connection groove again under the action of the rebound force of the first spring 30.

[0033] Two front and rear outer movable grooves are respectively arranged on the end faces of one side where the two shifting blocks 27 are close to each other. An inner movable groove is arranged on the inner side of each outer movable groove. The inner movable groove and the outer movable groove are connected through a connecting hole. The axis of the connecting hole is arranged horizontally along the left and right direction. The inner diameter of the connecting hole is smaller than the inner diameters of the inner movable groove and the outer movable groove. A sliding rod is slidably inserted in the connecting hole. A circular baffle 32 is fixedly arranged at one end of the sliding rod extending into the inner movable groove. A moving seat 31 is fixedly arranged at one end of the sliding rod extending into the outer movable groove. A second spring 33 is sleeved on the outer side of the sliding rod. The second spring 33 is located inside the outer movable groove. The two ends of the second spring 33 are respectively connected to the inner side of the outer movable groove and the moving seat 31. A pulley 34 is rotatably arranged at one end of the outer side of the moving seat 31. The pulley 34 extends to the outside of the opening of the outer movable groove.

[0034] The present invention provides a method for using a rail derailer for a rail vehicle for cross-track track change, comprising the following steps: Step 1, first connect all electrical equipment with wires and power on, then pull the connecting rods 7 in the connecting plates 6 on both sides outward, at this time the tension springs 9 are in a stretched state, and the positioning blocks 10 on the left and right sides move outward, thereby controlling the parts connected to the lower ends of the positioning blocks 10 to move outward as a whole, and then controlling the shifting blocks 27 on the left and right sides to move outward, so that the pulleys 34 on the shifting blocks 27 abut against the side of the guide rail 1; then turn the hand wheel 16, control the rotation of the worm 14 through the hand wheel 16, and control the rotation of the worm wheel 13 through the meshing transmission of the worm 14 and the worm wheel 13, and then connect the worm wheel 13 and the screw 12 through the threaded connection, when the worm wheel 13 rotates, the screw 12 is controlled to rise and fall, and when the screw 12 rises and falls, the lower end shifting block 27 is controlled to rise and fall, and after the shifting block 27 is moved to a suitable height on the side of the guide rail 1, stop turning the hand wheel 16, and control the self-locking of the screw 12 through the worm wheel 13 and the worm 14.

[0035] Step 2. After the position of the shift block 27 is determined, the rail vehicle 4 is started and the wheel 5 moves on the guide rail 1. At this time, the pulley 34 slides against the side of the guide rail 1. When the rail vehicle 4 moves to the intersection of the guide rail 1 and continues to move, the head of the shift block 27 hits the rotating guide rail on the track divider 3, thereby controlling the track divider 3 to rotate, so that the rotating guide rail is connected to the guide rail 1 in the forward direction of the rail vehicle 4, and the rail vehicle 4 can pass smoothly.

[0036] Step 3: When the rail vehicle 4 moves, the rail 1 and the wheel 5 are not completely in contact, which causes the rail vehicle 4 to shake, and then causes the shift block 27 to swing. When the shift block 27 swings, the first spring 30 causes the shift block 27 to move toward the outside of the connection slot of the connection seat 26, and then the pulley 34 abuts against the side of the rail 1. Secondly, the second spring 33 causes the pulley 34 to move toward the outside of the outer movable slot, and then the pulley 34 always stably abuts against the side of the rail 1.

[0037] Step 4: When the rail vehicle 4 moves onto the curved guide rail 1, start the electric push rod 19, and 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 that the rotating rod 21 can be controlled to rotate. When the pulley 34 moves on the curved guide rail 1 with the rail vehicle 4, the rotating rod 21 is controlled to make an adaptive deflection through the torsion spring 22, thereby controlling the shift block 27 to make an adaptive deflection, thereby keeping the pulley 34 against the side of the guide rail 1. When driving on the linear guide rail 1, start the electric push rod 19 to control the piston rod to retract, thereby controlling the positioning ring 24 to rise, and then meshing with the spline sleeve 23, thereby locking the rotating rod 21, so that the rotating rod 21 no longer rotates; when the transportation task of the rail vehicle 4 is completed, all electrical equipment is powered off.
