Description

Technical Field

[0001] The invention belongs to the technical field of rail retracting transportation, and particularly relates to an electric rail shifting device used for rail retracting operation. Background Art

[0002] When collecting 500m long rails by a long rail transport vehicle group, after the rails are collected to the long rail transport vehicle group, the rails on the vehicle need to be shifted to a designated position to facilitate the storage of the rails on the vehicle. To achieve the rail shifting, at present, most of them adopt the manual shifting method. During the long-term rail shifting, manual operation is easily affected by fatigue factors and cannot continuously maintain high efficiency. Moreover, manual operation is also easily restricted by the environment, which not only reduces the efficiency but also increases the danger level. At the same time, manual rail shifting also increases the personnel management cost. Summary of the Invention

[0003] The invention intends to propose an electric rail shifting device used for rail retracting operation. By using the electric rail shifting device instead of manual rail shifting, it can not only effectively improve the efficiency but also reduce the labor cost.

[0004] For this reason, the technical solution adopted by the invention is as follows: an electric rail shifting device used for rail retracting operation, including a first column, a rail shifting column, and a second column arranged in the old rail storage device in the long rail transport vehicle. The rail shifting column is rotatably arranged on the base through a rotating block. The base is arranged on the old rail storage device, and the rail shifting column and the first column are respectively arranged at the left and right sides of the left and right sides of the old rail storage position at intervals. The rail shifting column and the second column are arranged at intervals along the front and back directions of the old rail retracting direction. A rail shifting cross beam for shifting the old rails to a designated position is arranged on the rail shifting column and the first column. A rail shifting claw capable of moving left and right is arranged on the rail shifting cross beam through a left and right moving component. An up and down moving component for realizing the up and down movement of the rail shifting cross beam is arranged on the rail shifting column. When the rail shifting column is rotated, one end of the rail shifting cross beam can be moved from the first column to the second column.

[0005] As a preference in the above solution, a plurality of movable support components for supporting the rail shifting cross beam are arranged at intervals up and down on the first column. The movable support components are used to ensure that the rail shifting cross beam can accurately stop at the corresponding height where the old rails need to be shifted. The movable support component includes a movable support block hinged at one end to the first column. Support blocking blocks are arranged at the positions corresponding to the movable support blocks on the first column. When the movable support block is rotated, the other end of the movable support block is blocked by the support blocking block, and the rail shifting cross beam can be supported by the movable support block, thereby preventing the rail shifting cross beam from moving downward.

[0006] Further preferably, a groove recessed inward is arranged in a circle at the lower end of the rail shifting claw, and the width of the groove is greater than the height of the bottom wing plate of the old rail.

[0007] Further preferably, an insertion hole for the pawl to be inserted into is provided at the bottom of the old rail storage device.

[0008] Further preferably, a sliding support assembly for supporting the rail shifting cross beam when the pawl is not working is provided at the upper end of the first upright post. The sliding support assembly includes a sliding support block slidably arranged at the upper end of the first upright post. Limit blocks for preventing the sliding support block from moving out of the sliding groove are arranged at both ends of the sliding support block. A sliding stop block is hinged to one end of the sliding support block away from the rail shifting cross beam. When the sliding support block slides away from the rail shifting cross beam, the sliding stop block rotates to be parallel to the sliding support block. At this time, the other end of the sliding stop block can abut against the upper end of the first upright post, thereby preventing the sliding support block from returning to its position and affecting the up and down movement of the rail shifting cross beam. When the sliding support block slides close to the rail shifting cross beam in place, at this time, the sliding stop block rotates to be perpendicular to the sliding support block, and the rail shifting cross beam is supported by the sliding support block.

[0009] Further preferably, a rotating protrusion is provided at the lower end of the rotating block, and a rotating groove for the rotating protrusion to extend into is provided on the base. A copper sleeve for facilitating rotation is arranged between the rotating groove and the rotating protrusion.

[0010] Further preferably, a limit groove is provided on the rotating block, and a limit protrusion matching the limit groove is provided on the base. The cross sections of the rotating block and the base are both rectangular. The limit protrusion is arranged at one end of the long side of the rectangle, so that while not affecting the rotation of the rotating block, the limit protrusion can block the short side of the rotating block after the rotating block rotates, preventing the rotating block from continuing to rotate.

[0011] Further preferably, an L-shaped limit baffle is provided on the second upright post. The horizontal section of the limit baffle is used to support the rail shifting cross beam, and the vertical section of the limit baffle is used to prevent the rail shifting cross beam from continuing to rotate.

[0012] Further preferably, an anti-rotation structure for preventing the rail shifting cross beam from rotating when the pawl is working is further included. The anti-rotation structure includes a first anti-rotation block arranged on the rail shifting cross beam. An anti-rotation sliding groove for the first anti-rotation block to be inserted into and move up and down is provided on the first upright post. An activity stop block for preventing the first anti-rotation block from moving up and down is arranged at the upper end of the anti-rotation sliding groove. One end of the activity stop block is hinged to the upper end of the first upright post.

[0013] Further preferably, a limit structure for restricting the rotation of the rail shifting cross beam towards the first upright post is further included. The limit structure includes a second anti-rotation block arranged on the rail shifting cross beam. A movable pin is provided on the second upright post. When the rail shifting cross beam rotates to the second upright post, the movable pin can be inserted into the groove between the second anti-rotation block and the rail shifting cross beam.

[0014] Further preferably, a limit slot for inserting a limit pin is provided on one side of the base close to the second column, a placement block for placing the limit pin is provided on the track shifting column, and a limit cable is provided between the limit pin and the track shifting column to prevent the limit pin from falling off.

[0015] Advantages of the present invention:

[0016] 1) The track shifting operation of the long rail is realized by driving the pawl through the left and right moving assembly, and the up and down movement of the track shifting cross beam is realized by the up and down moving assembly, so that the whole device can be used for the track shifting operation of long rails at different heights.

[0017] 2) The automation of track shifting is realized through the left and right moving assembly and the up and down moving assembly, which can not only effectively improve the efficiency, but also reduce the labor cost.

[0018] 3) The first column, the track shifting column and the track shifting cross beam are all independently modularized, so that the whole track shifting device can not only be installed on existing vehicles, but also be applicable to newly built vehicles, that is, the application range of the present application is wide.

[0019] 4) A second column is also provided to rotate the track shifting cross beam so that the track shifting cross beam is parallel to the long rail, which is convenient for the subsequent removal of the old rail. A rotation prevention structure is also provided to effectively prevent the track shifting cross beam from rotating when the pawl is working. Description of the drawings

Detailed implementation manners

[0031] The present invention will be further described below through embodiments in conjunction with the drawings:

[0032] As Figures 1 - 10 shown, an electric rail shifting device for rail collecting operation is mainly arranged in the used rail storage device of the long rail transport vehicle, and is used to realize that when the long rail transport vehicle recovers used rails, the used rails are shifted to other positions, so as to ensure the storage of used rails. The long rail transport vehicle is a prior art, which is mainly used to realize the loading, transportation, unloading of new long rails and the recovery of used rails, that is, to realize the replacement of new long rails and used rails. Among them, there is a special used rail storage device for used rail recovery. Common used rail storage devices include a plurality of storage racks arranged at intervals before and after, and a plurality of storage platforms are arranged at intervals up and down on each storage rack.

[0033] The electric rail shifting device mainly consists of a first column 100, a rail shifting column 600, a left - right moving assembly 300, an up - down moving assembly 400, and a rail shifting crossbeam 200. Among them, the rail shifting column 600 and the first column 100 are respectively arranged at the left and right sides of the storage position of the old rail 510 at intervals, that is, the rail shifting column 600 and the first column 100 correspond to the left and right sides of the storage rack. The rail shifting crossbeam 200 is arranged on the rail shifting column 600 and the first column 100, and is used to distribute the old rails to the designated positions. There are downward - extending pawls 310 arranged inside the rail shifting crossbeam. The left - right moving assembly is arranged on the rail shifting crossbeam 200 and is used to realize the left - right movement of the pawls inside the rail shifting crossbeam. The up - down moving assembly is arranged on the rail shifting column and is used to realize the up - down movement of the rail shifting crossbeam, so that the distribution of the rails on each storage platform can be realized.

[0034] When the pawls realize the distribution of the old rails on different storage platforms, in order to ensure the support of the rail shifting crossbeam, a number of movable support assemblies 110 for supporting the rail shifting crossbeam 200 are arranged at intervals up and down on the first column 100. The movable support assemblies 110 are used to ensure that the rail shifting crossbeam 200 can accurately stop at the corresponding height where the old rails need to be distributed.

[0035] The movable support assembly 110 includes a movable support block 111 and a support blocking block 112. One end of the movable support block 111 is hinged to the first column 100, and the support blocking block 112 is arranged on the first column 100. When the movable support block is rotated, the other end of the movable support block can be supported by the support blocking block. At this time, the rail shifting crossbeam can be supported by the movable support block 111, thereby preventing the rail shifting crossbeam 200 from moving downward.

[0036] In order to ensure that the pawls can realize the distribution of the old rails, a groove that is recessed inward is arranged at the lower end of the pawl 310, and the width of the groove is greater than the height of the bottom flange of the old rail. As Figure 9 shown, the width W of the groove is greater than the height H of the bottom flange of the old rail. When encountering jams during the rail shifting process, by controlling above the rail shifting crossbeam, the pawls can lift the old rail through the cooperation of the groove and the bottom flange of the old rail, so as to ensure the smooth rail shifting of the pawls.

[0037] During the stages of new rail loading, new rail transportation, and rail unloading on the line, the entire rail shifting device does not participate in the operation. Since one end of the rail shifting crossbeam is arranged on the first column, an insertion hole for the pawls to be inserted can be arranged at the bottom of the old rail storage device 500. At this time, the rail shifting crossbeam is lowered to the lowest position, and the pawls are inserted into the insertion hole.

[0038] To facilitate the placement of the rail shifting crossbeam in the storage platform when it is filled with old rails, and prevent the pawls from interfering with the old rails, a sliding support assembly 120 is provided at the upper end of the first column 100 for supporting the rail shifting crossbeam when the pawls 310 are not working. Specifically, the sliding support assembly 120 includes a sliding support block 121 slidably disposed at the upper end of the first column 100, and limit blocks 122 for preventing the sliding support block 121 from moving out of the chute are provided at both ends of the sliding support block 121. A sliding stop block 123 is hinged to the end of the sliding support block 121 away from the rail shifting crossbeam.

[0039] When the sliding support block 121 slides away from the rail shifting crossbeam, the sliding stop block 123 rotates to be parallel to the sliding support block. At this time, the other end of the sliding stop block 123 can abut against the upper end of the first column 100, thereby preventing the sliding support block 121 from returning to its position and affecting the up and down movement of the rail shifting crossbeam. When the sliding support block 121 slides to the position close to the rail shifting crossbeam, the sliding stop block 123 rotates to be perpendicular to the sliding support block 121, and the rail shifting crossbeam is supported by the sliding support block. It is set as a sliding support, which is convenient for the rail shifting crossbeam to move down without having to move up first and then move down.

[0040] To facilitate the unloading of the old rails after the storage platform is filled with old rails, the electric rail shifting device further includes a second column 700. The rail shifting column 600 and the second column 700 are arranged at intervals along the rail receiving direction of the old rails. A rotating block 620 is provided at the bottom of the rail shifting column 600. The rotating block 620 is rotatably disposed on a base 630, and the base 630 is disposed on the old rail storage device. When the rail shifting column is rotated, one end of the rail shifting crossbeam can be moved from the first column to the second column, that is, the rail shifting crossbeam is made parallel to the old rails.

[0041] To achieve the rotation of the rotating block relative to the base, a rotating protrusion 621 is provided at the lower end of the rotating block 620. A rotating groove 631 for the rotating protrusion to extend into is provided on the base 630, and a copper sleeve 640 for facilitating rotation is provided between the rotating groove 631 and the rotating protrusion 621.

[0042] To ensure that the rail shifting crossbeam does not rotate excessively, an L-shaped limit baffle 710 is provided on the second column 700. The horizontal section of the limit baffle 710 is used to support the rail shifting crossbeam, and the vertical section is used to prevent the rail shifting crossbeam from continuing to rotate.

[0043] To prevent the rail shifting column from continuing to rotate after the rail shifting crossbeam rotates from the first column to the second column, a limit groove 622 is provided on the rotating block 620, and a limit protrusion 632 matching the limit groove is provided on the base 630. Preferably, the cross-sections of the rotating block 620 and the base 630 are both set to rectangles, and the long sides of the rectangles are in the front-back direction. The limit protrusion 632 is provided on the left-right outer long side of the rectangle, and the limit protrusion is at one end of the long side of the rectangle away from the second column, so that the limit protrusion can not affect the rotation of the rail shifting crossbeam towards the second column, that is, as shown in Figure 1 In the figure, it does not affect the counterclockwise rotation of the rail shifting column. After the rail shifting crossbeam rotates in place, the limit protrusion blocks the short side of the rotating block, thereby preventing the rotating block from continuing to rotate, that is, as shown in Figure 4 In the figure, it prevents the rail shifting column from rotating counterclockwise. When the rail shifting crossbeam is located on the first column, the limit protrusion can also prevent the rail shifting column from rotating towards the side where the rail shifting crossbeam moves away from the second column, that is, as shown in Figure 1 In the figure, it prevents the rail shifting column from rotating clockwise.

[0044] To prevent the rail shifting crossbeam from rotating when the rail shifting claw is working, an anti-rotation structure 130 is also provided. The anti-rotation structure 130 includes a first anti-rotation block 220 provided on the rail shifting crossbeam. An anti-rotation sliding groove for the first anti-rotation block 220 to insert and move up and down is provided on the first column 100. Preferably, a movable stop block 131 for preventing the first anti-rotation block from moving up and down is provided at the upper end of the anti-rotation sliding groove, and one end of the movable stop block 131 is hinged to the upper end of the first column 100. When the rail shifting crossbeam returns from the second column to the first column, the movable stop block rotates, so that the upper end of the anti-rotation sliding groove is in an open state. Then, under the action of the up-and-down moving assembly, the rail shifting crossbeam is supported by the sliding support assembly. At this time, the first anti-rotation block slides into the anti-rotation sliding groove, and then the movable stop block is rotated to block the upper end of the anti-rotation sliding groove.

[0045] To facilitate the rotation of the movable stop block, a rotation handle is provided on the side of the movable stop block away from the rail shifting crossbeam.

[0046] To prevent the rail shifting crossbeam from rotating randomly towards the first column when the rail shifting crossbeam rotates onto the second column, a limit structure 720 for restricting the rotation of the rail shifting crossbeam towards the first column is also provided. The limit structure includes a second anti-rotation block 230 provided on the rail shifting crossbeam, and a movable bolt 721 is provided on the second column 700. When the rail shifting crossbeam rotates onto the second column, the movable bolt 721 can be inserted into the groove between the second anti-rotation block 230 and the rail shifting crossbeam.

[0047] Preferably, the movable bolt 721 is arranged in an L shape. Insertion blocks 722, upper stoppers 723, support blocks 724 and lower stoppers 725 are arranged at intervals above and below the upper end of the second upright post. Insertion holes for the vertical section of the movable bolt to pass through are arranged on both the insertion block and the upper stopper. The upper stopper is used to prevent the horizontal section of the movable bolt from moving upward, and the lower stopper is used to prevent the horizontal section of the movable bolt from moving downward. The support block is located on either the left or right side of the upper stopper or the lower stopper and is used to support the horizontal section of the movable bolt. Preferably, a clamping groove for restricting the random movement of the lower end of the movable bolt is arranged on the support block. A door bolt structure is formed by the movable bolt, the insertion block, the upper stopper, the support block, the lower stopper and the second anti-rotation block.

[0048] To prevent the rail-pulling upright post from rotating when the rail-pulling cross beam rotates onto the second upright post, a limit slot 633 for inserting a limit pin 650 is arranged on one side of the base 630 close to the second upright post 700. When the rail-pulling cross beam rotates onto the second upright post, the limit pin 650 is inserted into the limit slot to prevent the rail-pulling upright post from rotating. To prevent the loss of the limit pin, a placement block 660 for placing the limit pin is arranged on the rail-pulling upright post 600. Meanwhile, a limit cable 670 for preventing the limit pin from falling is arranged between the limit pin 650 and the rail-pulling upright post 600.

[0049] Preferably, the left-right moving assembly 300 includes a left-right driving assembly 330 and a sliding trolley 320. The sliding trolley 320 is located inside the rail-pulling cross beam. The pawl 310 is arranged on the sliding trolley 320, and the lower end of the pawl extends downward out of the rail-pulling cross beam. The left-right driving assembly is arranged at one end of the rail-pulling cross beam 200 far from the rail-pulling upright post. The left-right driving assembly includes a left-right driving motor 331 and a reducer 332.

[0050] To realize the left-right movement of the sliding trolley inside the rail-pulling cross beam, a lead screw-nut mechanism or a sprocket-chain mechanism for driving the sliding trolley to move is also arranged, and a first transmission mechanism is arranged between the reducer and the lead screw-nut mechanism or the sprocket-chain mechanism.

[0051] The sliding trolley 320 includes a sliding body 321. Moving wheels 322 capable of moving inside the rail-pulling cross beam are arranged on both the front and rear sides of the sliding body 321, and the chain or the lead screw-nut is fixedly connected to the sliding body.

[0052] Preferably, the up-and-down moving component 400 includes an up-and-down driving component 440 and a lead screw 410 which is arranged in the track shifting column 600 in an up-and-down extending manner. A lead screw nut 420 is screwed on the lead screw 410. A vertical pulley 430 is arranged outside the lead screw nut 420. One end of the track shifting cross beam 200 is arranged on the vertical pulley 430 through a mounting plate 210. The up-and-down driving component 440 includes an up-and-down driving motor 441 and a second transmission mechanism. The up-and-down driving component 440 is arranged at the upper end of the track shifting column and is used to rotate the lead screw. Through the cooperation of the lead screw and the lead screw nut, the vertical movement of the vertical pulley is realized.

[0053] Both the first transmission mechanism and the second transmission mechanism can adopt a sprocket and chain transmission mechanism. To protect the first transmission mechanism and the second transmission mechanism, protective covers are arranged outside both the first transmission mechanism and the second transmission mechanism.

[0054] Preferably, the vertical pulley 430 includes a vertical pulley main body 431 arranged outside the lead screw nut 420. A roller 432 capable of moving up and down in the track shifting column is arranged on the vertical pulley main body 431.

[0055] To reduce the weight when the track shifting column rotates, the up-and-down driving component is arranged on the storage rack through a mounting structure. The mounting structure includes a motor mounting plate 442 and a motor mounting seat 443. The motor mounting seat 443 is arranged on the storage rack. The motor mounting plate 442 is arranged on the motor mounting seat. One end of the motor mounting plate extends to the top surface of the track shifting column. The up-and-down driving motor 441 is arranged on the motor mounting plate 442, and the up-and-down driving motor is located between the motor mounting seat and the track shifting column. The second transmission mechanism is arranged on the motor mounting plate 442 and is used to connect the output end of the up-and-down driving motor with the upper end of the lead screw 410, that is, the upper end of the lead screw 410 passes through the motor mounting plate 442 and then extends into the second transmission mechanism.

[0056] To further fix the up-and-down driving motor, a motor baffle 445 located below the up-and-down driving motor is arranged at the lower end of the motor mounting seat.

[0057] To facilitate the fixation of the upper and lower ends of the lead screw, the lower end of the lead screw is arranged in a rotating block through a bearing. A lead screw seat 610 for the lead screw 410 to pass through is arranged at the upper end of the track shifting column 600. Bearings are arranged between the lead screw seat 610 and the lead screw 410, and between the lead screw 410 and the motor mounting plate 442. To ensure the installation of the bearings, bearing mounting sleeves fixed to the lead screw seat or the motor mounting plate are arranged outside the bearings.
