Abstract
Description
Technical Field
[0001] This utility model relates to the field of transportation technology, and in particular to a transverse reversing device. Background Technology
[0002] In the steel coil transport line renovation project, the renovation space is small, and there is not enough space to place a double row of turntables at the end to realize the turning of pallet trucks. Therefore, it is necessary to use a reversing device to achieve this.
[0003] The prior art discloses a lateral movement device and a pallet truck steel coil transportation system (Publication No.: CN212502527U), used for lateral movement of pallet trucks. The lateral movement device includes: a lateral movement platform, a slewing bearing, a rack, a rack mounting seat, a rotary table, and two lateral movement tracks. The lateral movement platform is movably mounted on the two lateral movement tracks. The fixed part of the slewing bearing is mounted on the lateral movement platform. The rack mounting seat is fixedly connected to one of the two lateral movement tracks, and the rack is fixedly mounted on the rack mounting seat, meshing with the slewing bearing. The rotary table is fixedly mounted on the rotating part of the slewing bearing, and the pallet truck can drive into or out of the rotary table.
[0004] In the existing technology, a rotatable gear is set on the pallet truck, and the turntable is pushed by the meshing of the rack and pinion. The direction is changed during the movement of the vehicle. However, the gear and rack are always meshed, which restricts the rotation of the turntable by the movement of the vehicle. The two are bound together, and the connection between the gear and rack cannot be broken during the movement of the pallet truck. The rotation is limited by the space during the rotation process, which has certain room for optimization.
[0005] Therefore, we propose a transverse commutation device. Utility Model Content

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a transverse reversing device, comprising:
[0008] A traverse vehicle and tracks, wherein the traverse vehicle is movably mounted on two tracks, and a gear is rotatably mounted on the top of the traverse vehicle, and a platform is fixedly mounted on the top of the gear;
[0009] A drive structure, located on one side of the traversing vehicle, is used to drive the gear to rotate. The drive structure includes a contact block, a base, a slide, and a push cylinder. The contact block is fixedly connected to the base, the base is slidably connected to the slide, the push cylinder is fixedly connected to the slide, and the output shaft of the push cylinder is fixedly connected to the base. The push cylinder can push the base so that the contact block abuts against the gear.
[0010] In a preferred embodiment of this utility model, the drive structure further includes a mounting plate, which is fixedly installed with the track, and the slide is slidably disposed on the top of the mounting plate.
[0011] In a preferred embodiment of this utility model, the drive structure further includes a fixed block, a lead screw, and a motor.

[0012] In a preferred embodiment of this utility model, a mounting base is fixedly mounted on one side of the mounting plate, the lead screw is fixedly connected to the mounting base, and the lead screw is rotatably connected to the mounting base.
[0013] In a preferred embodiment of this utility model, the fixing block is fixedly installed at the bottom of the slide table, the fixing block has a circular hole, a threaded sleeve is fixedly installed in the circular hole, and the threaded rod is threadedly connected to the threaded sleeve.
[0014] In a preferred embodiment of this utility model, the top of the mounting plate is provided with a sliding groove, and the bottom of the slide table is provided with an integrally formed protrusion, which is adapted to the sliding groove and slidably disposed in the sliding groove.
[0015] In a preferred embodiment of this utility model, the driving structure further includes guide grooves and limiting ribs.

Beneficial effects
[0017] This utility model provides a transverse reversing device. It has the following beneficial effects:
[0018] 1. This transverse reversing device, through the contact block and the gear abutting and engaging, can drive the gear to rotate and adjust the position of the platform. After the contact block and the gear are separated, the transverse vehicle will not cause the gear to rotate and reverse during the movement. It has a flexible usage mode, so that the movement of the transverse vehicle and the rotation of the gear do not interfere with each other. Depending on the site, the gear and the contact block can be engaged intermittently to reverse, breaking the site's limitation on the reversing direction.
[0019] 2. This transverse reversing device uses a push cylinder to push a base to slide on a slide. The slide moves the base closer to the gear, and the base pushes a contact block to abut the gear. The side of the contact block closest to the gear can have teeth. When the contact block, which has a certain toughness and deformation capacity, abuts the gear, even if the teeth and teeth cannot fully mesh, the contact force between the contact block and the gear can still drive the gear to rotate, thus achieving reversing. It has high stability and a longer service life. The contact block can be fixed to one side of the base with bolts, and the detachable contact block is convenient for replacement during maintenance.
[0020] 3. This transverse reversing device uses a motor to drive a lead screw to rotate. The lead screw moves a fixed block, causing the slide to slide along the mounting plate. The protrusion at the bottom of the slide slides in the groove, allowing the slide to slide along the mounting plate. This allows the contact block and the base to move along the track extension direction, driving the gear to rotate. This makes the gear rotation speed not limited by the transverse carriage displacement speed, and has the characteristic of flexibly adjusting the gear rotation reversing speed.
[0021] 4. This transverse reversing device uses limiting ribs to slide in the guide groove, which allows the base to maintain stable linear sliding. At the same time, after the contact block contacts the gear, the limiting ribs can provide sufficient limiting for the base, preventing the base from being pushed as the gear rotates, thus ensuring the pushing effect on the gear and the stability of the reversing.

[0029] A transverse commutation device, such as Figure 1 and Figure 2As shown, it includes:
[0030] The transverse trolley 10 and the tracks 11 are movably mounted on the two tracks 11. A gear 12 is rotatably mounted on the top of the transverse trolley 10, and a platform 13 is fixedly mounted on the top of the gear 12. Specifically, a roller is rotatably connected to the bottom of the transverse trolley 10, and a drive motor and a reducer are also fixedly mounted on the bottom of the transverse trolley 10. The output shaft of the drive motor is connected to the input end of the reducer, and the output end of the reducer is fixedly connected to the roller. The displacement of the transverse trolley 10 is achieved by driving the roller to roll on the tracks 11. A guide rail is fixedly mounted on the top of the platform 13. The pallet cart on the guide rail can be adjusted by rotating the platform 13 through the gear 12. For the transportation of steel coils or steel pipes, it is convenient to change the direction of the pallet cart.
[0031] like Figure 2 and Figure 3 As shown, the drive structure is located on one side of the transverse carriage 10 to drive the gear 12 to rotate. The drive structure includes a contact block 20, a base 21, a slide 22, and a push cylinder 23. The contact block 20 is fixedly connected to the base 21, the base 21 is slidably connected to the slide 22, the push cylinder 23 is fixedly connected to the slide 22, and the output shaft of the push cylinder 23 is fixedly connected to the base 21. The push cylinder 23 can push the base 21 so that the contact block 20 abuts against the gear 12. The drive structure also includes a mounting plate 24, which is fixedly installed on the track 11. The slide 22 is slidably disposed on the top of the mounting plate 24.
[0032] In this design, the gear 12 is mainly contacted by a rubber contact block 20. Since the traverse vehicle 10 moves along the track 11, the contact block 20 abuts against the gear 12, which can push the gear 12 to rotate and adjust the position of the platform 13. After the contact block 20 is separated from the gear 12, the traverse vehicle 10 will not cause the gear 12 to rotate and change direction during the journey. This design offers a flexible way of use, ensuring that the journey of the traverse vehicle 10 and the rotation of the gear 12 do not interfere with each other.
[0033] The push cylinder 23 pushes the base 21 to slide on the slide table 22. The slide table 22 drives the base 21 to approach the gear 12. Then the base 21 pushes the contact block 20 to abut against the gear 12. The side of the contact block 20 that is close to the gear 12 can be opened with teeth. When the contact block 20 with a certain toughness and deformation ability abuts against the gear 12, even if the teeth and teeth cannot be fully meshed, the contact force between the contact block 20 and the gear 12 can drive the gear 12 to rotate to achieve reversal. It has high stability and longer service life. The contact block 20 can be fixed to one side of the base 21 with bolts. The detachable contact block 20 is convenient for replacement during maintenance.
[0034] like Figure 4As shown, the drive structure also includes a fixed block 25, a lead screw 26, and a motor 27. The motor 27 is fixedly installed on the mounting plate 24, the lead screw 26 is fixedly connected to the output shaft of the motor 27, the fixed block 25 is fixedly installed on the slide table 22, the lead screw 26 is threadedly connected to the fixed block 25, a mounting seat is fixedly installed on one side of the mounting plate 24, the lead screw 26 is fixedly connected to the mounting seat, the lead screw 26 is rotatably connected to the mounting seat, the fixed block 25 is fixedly installed on the bottom of the slide table 22, the fixed block 25 has a round hole, a threaded sleeve is fixedly installed in the round hole, the lead screw 26 is threadedly connected to the threaded sleeve, a sliding groove is opened on the top of the mounting plate 24, and an integrally formed protrusion is provided on the bottom of the slide table 22. The protrusion is adapted to the sliding groove and slidably disposed in the sliding groove.
[0035] The motor 27 drives the lead screw 26 to rotate, and the lead screw 26 moves the fixed block 25 to make the slide table 22 slide along the mounting plate 24. The protrusion at the bottom of the slide table 22 slides in the slide groove, so that the slide table 22 slides along the mounting plate 24. In turn, the contact block 20 and the base 21 can move along the extension direction of the track 11 to drive the gear 12 to rotate, so that the rotation speed of the gear 12 is not limited by the displacement speed of the transverse car 10, and has the characteristic of flexibly adjusting the rotation speed of the gear 12.
[0036] like Figure 5 and Figure 6 As shown, the drive structure also includes guide grooves 30 and limiting ribs 31. Two guide grooves 30 are opened on the top of the slide table 22, and two limiting ribs 31 are fixed on the bottom of the base 21. The base 21 is slidably connected to the slide table 22 through the limiting ribs 31. The limiting ribs 31 form rectangular rods. The guide grooves 30 are adapted to the limiting ribs 31. The two limiting ribs 31 are slidably set in the corresponding guide grooves 30. The base 21 is fixedly installed on the top of the limiting ribs 31. In this solution, the limiting ribs 31 slide in the guide grooves 30, so that the base 21 maintains stable linear sliding. At the same time, after the contact block 20 contacts the gear 12, the limiting ribs 31 can provide sufficient limiting for the base 21, suppressing the base 21 from being pushed as the gear 12 rotates, and ensuring the pushing effect on the gear 12 and the stability of the reversing.
[0037] The working principle of this utility model is as follows: The pusher cylinder 23 pushes the base 21 to slide on the slide table 22. The limiting rib 31 slides within the guide groove 30, ensuring stable linear sliding of the base 21. The slide table 22 moves the base 21 closer to the gear 12, which in turn pushes the contact block 20 to abut against the gear 12. The side of the contact block 20 closest to the gear 12 can have teeth. The contact block 20, possessing a certain degree of toughness and deformation capability, can still drive the gear 12 to rotate through the contact force between the contact block 20 and the gear 12, even if the teeth and teeth cannot fully mesh. After the contact block 20 is separated from the gear 12, the transverse car 10 will not cause the gear 12 to rotate in a different direction during its travel. The motor 27 drives the lead screw 26 to rotate, and the lead screw 26 moves the fixed block 25 to make the slide table 22 slide along the mounting plate 24. The protrusion at the bottom of the slide table 22 slides in the slide groove, so that the slide table 22 slides along the mounting plate 24. Then the contact block 20 and the base 21 can move along the extension direction of the track 11 to drive the gear 12 to rotate, so that the rotation speed of the gear 12 is not limited by the displacement speed of the transverse car 10, thus realizing the adjustment of the rotation speed of the gear 12.
