Description

Technical Field

[0001] The present invention relates to the field of rail transportation equipment, and in particular to a busbar type automated rail transmission device and a transmission method thereof. Background Art

[0002] With the advancement of society, high-speed rail plays an increasingly important role in people's daily lives, and with it comes an increasing demand for rails during high-speed rail construction. The production of rails for railway switches requires a series of processes, including sawing, CNC drilling, forging, and cross-section heat treatment. After each process, the rails are transferred horizontally to the corresponding rack, which then transfers them to the loading rollers for the next process.

[0003] Currently, the process of horizontally transporting rails in China typically involves pulling or pushing the rails, or using actuators to create an inclined surface to transfer the rails from the longitudinal transport rollers to the rack. However, these methods have significant technical flaws and operational issues. During rail transport using these methods, due to the height difference between the longitudinal transport rollers and the rack, the rail bottom can rub against the rollers and rack, resulting in horizontal scratches on the rail bottom and damage to the rail.

[0004] Conventional rail lifting devices using hydraulic cylinders suffer from complex hydraulic power systems, low efficiency, high costs, long pipelines, and poor synchronization. Furthermore, hydraulic cylinder lifting requires a matching drag chain structure to protect the internal hydraulic lines and cables. Furthermore, long-distance lateral transport can lead to unwieldy structures and oil leakage.

[0005] In addition, existing transmission equipment generally has a low degree of automation and requires manual assistance during use, which makes it difficult to meet the current needs of automated production. Summary of the Invention

[0006] In order to solve the above technical problems, the present invention provides a busbar-type automated rail transmission device and a transmission method thereof. The device is composed of multiple sets of transverse lifting equipment, which are arranged at intervals in the length direction of the rails and can automatically transmit rails of different lengths and specifications. The transverse lifting equipment uses a motor as an actuator, and realizes transverse transmission through a servo motor-driven chain. A conductive busbar is designed on the frame of the transverse lifting equipment, and power is provided by the busbar instead of the traditional drag chain cable, making the structure more compact and convenient, and using a 24V low-voltage DC motor to drive the elevator to realize rail lifting, further ensuring the safety performance of the equipment without the risk of electric shock.

[0007] The technical solution adopted in the present invention is:

[0012] The output shaft of the lifting servo motor and the input shaft of the lifting transmission mechanism are coaxially fixedly connected, and the output end of the lifting transmission mechanism passes upward through the machine base and is fixedly connected to the lifting and lowering support plate. The lifting and lowering support plate is equipped with a rail positioning sensor on the side facing the rail, and a bus bar is provided on the side between the two ends of the frame along a direction perpendicular to the transmission direction of the rail. The slider is electrically connected to the lifting servo motor, the rail positioning sensor and the bus bar respectively.

The tensioning seat is fixedly mounted on one end of the frame away from the transverse servo motor. The two ends of the driven wheel shaft pass through the tensioning seat and are respectively connected to the two tensioning adjustment components. The two tensioning adjustment components are both mounted on the tensioning seat and are symmetrically arranged at both ends of the driven wheel shaft. Each tensioning adjustment component includes a screw, a sliding seat and a disc spring. The screw is fixedly mounted on the tensioning seat. The sliding seat is slidably mounted on the outside of each screw. The sliding seat body is a sleeve structure. An outer flange is provided at one end of the sleeve structure.

[0018] The automated rail transmission method comprises the following steps:

[0019] S1. The rails are transported to the transverse lifting device through a set of conveyor rollers. The transverse lifting device sends a signal through the through-beam sensor and receives feedback from the reflector, and then sends the received signal to the controller;

[0020] S2. The controller controls the transverse mechanism to operate according to the received signal. The chain in the transverse mechanism drives the lifting mechanism to move horizontally toward the rail and move to the bottom of the rail.

[0021] S3. When the lifting mechanism moves to the lower end of the rail, the rail positioning sensor in the lifting mechanism is triggered, the lifting mechanism stops moving, and the controller controls the lifting mechanism to synchronously lift the rail;

[0022] S4. When the rail is lifted to a preset height, the controller controls the transverse movement mechanism to operate, and the chain in the transverse movement mechanism drives the lifting mechanism to move to a preset position on the pad. The controller controls the lifting mechanism to drop the rail and place it at the preset position on the pad.

[0023] S5. Use the transverse movement mechanism and the lifting mechanism to move from the preset position at the pad to another set of conveyor roller sets according to the same process as the above steps S2 to S4, so as to realize the automatic transmission of the rails.

[0024] The beneficial effects of the present invention are:

[0025] 1. This device adopts universal and modular design. According to the actual situation on site, an appropriate number of transverse lifting equipment is arranged, which can adapt to the transverse transmission between various rail processing processes.

[0026] 2. The design of this device realizes the automatic transverse transmission of rails. It can automatically identify the model of incoming rails and transfer the rails in an orderly manner to the rack storage pad. The stored rail model information will be transmitted to the information library of the controller. When the next process loading is carried out, the rail model information in the information library is read and the corresponding number of transverse lifting devices are activated to transfer the rails in an orderly manner to the next process loading roller.

[0027] 3. During rail traverse and lift, the bottom of the rail remains in contact with the lifting mechanism without relative displacement, preventing scratches and scrapes on the rail bottom. Each actuator of the device is motor-driven, offering low cost, high precision, simple structure, and safety and reliability. It automatically identifies rail specifications, enabling automated rail transportation, improving production efficiency, and reducing worker labor.

[0028] 4. This device adopts a non-standard symmetrical tensioning structure to avoid poor engagement and vibration of the chain. The controller of this device has the function of connecting to external devices and has strong expansion capabilities, which can adapt to different automated production line requirements.

[0029] 5. The base of the lifting mechanism is assembled from a frame structure and fixed with screws, which features a compact structure and high strength. The lifting support plate is universally designed to meet the needs of lifting various types of rails and is easy to disassemble and replace.

[0030] This device solves the problem of damaged rails caused by the existing transverse rail transmission method of pulling rails, pushing rails or using actuators to create inclined surfaces, the problem of insufficient automation in existing transverse rail transmission devices, and the problem of excessive reliance on vehicle transportation for rail transmission between processing production lines.

[0043] The transverse movement and lifting equipment includes a beam sensor 1, a roller track 2, a frame 3, a pad 4, a lifting mechanism 5, a reflector 7, an end baffle 8 and a transverse movement mechanism 9. A transverse movement mechanism 9 is installed on the frame 3, and the transverse movement mechanism 9 is arranged across the two ends of the frame 3. The transverse movement mechanism 9 has a built-in chain transmission structure and a lifting mechanism 5 is installed on the chain transmission structure.

[0044] Specifically, the height of the frame 3 is the same as the height of the conveyor roller, and a transverse movement mechanism 9 is installed at both ends of the frame 3. A rectangular groove is opened on the upper surface of the frame 3. The rectangular groove connects the transverse movement mechanisms 9 at both ends of the frame 3. The long side of the groove is perpendicular to the transmission direction of the rail and a lifting mechanism 5 that moves along the vertical transmission direction of the rail is installed in the groove. The transverse movement mechanism 9 is connected to the lifting mechanism 5 by a chain 14, and the transverse movement mechanism 9 drives the lifting mechanism 5 to move horizontally in the groove through the chain 14.

[0045] End baffles 8 for limiting the movement of the rails from the transverse lifting device are fixedly installed at both ends of the frame 3. A through-beam sensor 1 is provided on the end baffles 8. Two strip-shaped pads 4 arranged along the vertical rail transmission direction are fixedly installed on the top surface between the two ends of the frame 3 above the roller track 2. The upper surface of each pad 4 is provided with a reflector 7 for reflecting the signal of the through-beam sensor 1.

[0046] The upper end surfaces at both ends of the frame 3 are vertically provided with end baffles 8 for limiting the movement of the rails from the transverse lifting device.

[0049] The frame 3 is a bilaterally symmetrical structure, and the transverse beam is a welded structure of rectangular steel and steel plates. Reinforcement ribs are arranged and welded at weak locations such as columns and ends.

[0050] The present invention can also use a full-roller transmission frame to replace the pad 4 for the lateral transmission of the rails, so that the movement between the rails and the transmission frame is changed to a rolling mode, thereby avoiding scratches on the rails; for the process from the loading roller to the full-roller transmission frame or the full-roller transmission frame to the unloading roller, an actuator is used to form a roller transmission channel to replace the lifting mechanism 5, and then the loading or unloading of the rails is achieved by pulling or pushing the rails.

[0052] Lifting mechanism 5 Figure 5As shown, it includes a busbar 6, a machine base 24, rollers, a lifting support plate 25, a rail positioning sensor 26, a slide mounting plate 27, a lifting transmission mechanism 28 and a lifting servo motor 29. A plurality of rollers are provided on the machine base 24, and one side of the machine base 24 is connected in a rolling manner perpendicular to the rail transmission direction through the rollers and the roller track 2. The other side of the machine base 24 is fixedly connected to the chain 14. The lifting support plate 25 and the rail positioning sensor 26 are installed on the upper end surface of the machine base 24. The rail positioning sensor 26 is arranged on the side of the lifting support plate 25 along the rail transmission direction. The slide mounting plate 27 with a slide and the lifting transmission mechanism 28 and the lifting servo motor 29 for lifting the lifting support plate 25 are installed on the lower end surface of the machine base 24.

[0053] The output shaft of the lifting servo motor 29 is coaxially fixedly connected to the input shaft of the lifting transmission mechanism 28 through a coupling. The output end of the lifting transmission mechanism 28 passes upward through the machine base 24 and is fixedly connected to the lifting and lowering support plate 25.

The side between the two ends of the frame 3 is provided with a busbar 6 perpendicular to the transmission direction of the rail. The slider is electrically connected to the lifting servo motor 29, the rail positioning sensor 26, and the busbar 6 respectively.

[0054] Specifically, two roller rails 2 are arranged opposite each other on the side walls of the groove. The direction of the roller rails 2 is perpendicular to the transmission direction of the rails. The lifting mechanism 5 moves along the direction perpendicular to the transmission direction of the rails through the roller rails 2. The busbar 6 is installed on the side wall of one side of the groove along the direction perpendicular to the transmission direction of the rails. The busbar 6 is located below the roller rails 2 on the side wall of the groove. The lifting mechanism 5 is powered by the busbar 6 and the slide.

[0055] Specifically, the upper end surface of the machine base 24 is equipped with a lifting support plate 25 for lifting the rail and a rail positioning sensor 26 for positioning the rail. The rail positioning sensor 26 is located on the side of the lifting support plate 25 along the direction of rail transmission. A number of rollers are provided on both sides of the machine base 24 parallel to the side wall of the groove. In this embodiment, there are two rollers on the left and two rollers on the right, so that the machine base 24 can move in the groove perpendicular to the direction of rail transmission through the rollers and the roller track 2. Both sides of the side wall of the vertical groove of the machine base 24 are provided with protrusions with through holes. The machine base 24 is connected to the side wall of the groove perpendicular to the rail transmission through the through holes on the protrusions. The chain 14 in the transverse movement mechanism 9 is fixedly connected, and the transverse movement mechanism 9 drives the machine base 24 to move through the chain 14. The lower end surface of the machine base 24 is provided with a slide mounting plate 27 for installing a slide, and a lifting transmission mechanism 28 and a lifting servo motor 29 for lifting and lowering the lifting support plate 25. The lifting transmission mechanism 28 and the lifting servo motor 29 are connected through a coupling. The lifting servo motor 29 is installed on the side of the lifting transmission mechanism 28 to drive the lifting transmission mechanism 28 to lift and lower the lifting support plate 25. The slide cooperates with the bus bar 6 to control the on and off of the circuit of the lifting mechanism 5.

[0056] Furthermore, the traverse mechanism 9 is as follows Figure 3 As shown, it includes a traverse servo motor 10, a planetary reducer 11, a driving wheel shaft 12, a driving gear 13, a chain 14, a tensioning mechanism 15, a driven wheel shaft 16 and a driven gear 17; the traverse servo motor 10, the planetary reducer 11, the driving wheel shaft 12 and the driving gear 13 are arranged at one end of the frame 3, and the tensioning mechanism 15, the driven wheel shaft 16 and the driven gear 17 are arranged at the other end of the frame 3;

[0057] The lateral movement servo motor 10 and the planetary reducer 11 are fixedly mounted at one end of the frame 3, the driving wheel shaft 12 and the driving gear 13 are movably hingedly mounted on the frame 3, the output shaft of the lateral movement servo motor 10 is connected to the driving wheel shaft 12 through the planetary reducer 11, the output shaft of the lateral movement servo motor 10 is horizontally arranged and connected to the input end of the planetary reducer 11, the output end of the planetary reducer 4 is connected to the driving wheel shaft 12, the driving wheel shaft 12 is coaxially fixedly connected to the driving gear 13, the driving gear 13 is chain-drivenly connected to the driven gear 17 at the other end of the frame 3 through the chain 14, the driven gear 17 is coaxially connected to the driven wheel shaft 16, the driven wheel shaft 16 is connected to the tensioning mechanism 15, and the chain 14 is fixedly connected to the lifting mechanism 5.

[0058] The transverse servo motor 10 under the transverse mechanism 9 is started, and the planetary reducer 11 drives the driving wheel shaft 12 to rotate. The driving gear 13 on the driving wheel shaft 12 rotates synchronously with the shaft. Since the two ends of the chain 14 are respectively engaged with the driving gear 13 and the driven gear 17, the chain 14 drives the driven gear 17 to rotate, and the tensioning mechanism 15 maintains the appropriate tension of the chain 14. The driven gear 17 is fixedly connected to the driven wheel shaft 16, thereby driving the driven wheel shaft 16 to rotate synchronously, so that the chain 14 moves in a direction perpendicular to the direction of rail transmission, and then drives the lifting mechanism 5 fixedly connected to the chain 14 to move in a direction perpendicular to the direction of rail transmission.

[0059] The lateral movement servo motor 10 adjusts the output speed range through the planetary reducer 11, drives the driving wheel shaft 12 to synchronously drive the driving gear 13 installed on the shaft, and the driving gear 13 and the driven gear 17 drive the lifting mechanism 5 to move along the roller track 2 through the chain 14.

[0060] Tensioning mechanism such as Figure 4As shown, it includes a tensioning adjustment component, a rolling bearing 21, a retaining ring 22 and a tensioning seat 23. The tensioning seat 23 is fixedly mounted on one end of the frame 3 away from the transverse servo motor 10. The two ends of the driven wheel shaft 16 pass through the tensioning seat 23 and are respectively connected to the two tensioning adjustment components. The two tensioning adjustment components are both mounted on the tensioning seat 23 and are symmetrically arranged at both ends of the driven wheel shaft 16. Each tensioning adjustment component includes a screw 18, a sliding seat 19 and a disc spring 20. The two ends of the screw 18 are fixedly supported and mounted on the tensioning seat 23 by nuts. The sliding seat 19 is slidably mounted on the outside of each screw 18. The main body of the sliding seat 19 is a sleeve structure. An outer flange is provided at one end of the sleeve structure. A radial through hole is opened at the end of the driven wheel shaft 16.

[0061] The end of the sleeve structure without an outer flange passes through the radial through holes of the disc spring 20 and the driven wheel shaft 16 outward in sequence. The disc springs are arranged in a matched form. The two ends of the disc spring 20 are respectively connected to the outer wall of the driven wheel shaft 16 and the outer flange and are compressed. The screw 18 is set as a thread at the end close to the sleeve structure with an outer flange. Two nuts are mounted on the thread, one of the two nuts is connected to the outer flange, and the two nuts are used to limit and fix the position of the sliding seat 19, the disc spring 20 and the driven wheel shaft 16. The two nuts are tightened together for fixing. A rolling bearing 21 is concentrically arranged between the driven wheel shaft 16 and the driven gear 17, and a retaining ring 22 for centrally mounting the driven gear 17 is provided on both sides of the driven gear 17.

[0062] The tensioning mechanism is used to tension the chain 14 at the driven wheel structure.

The degree of tension can be adjusted according to actual usage conditions.

[0063] The automated rail transmission device also includes a controller, and the transverse lifting device and the conveyor roller are both electrically connected to the controller. The controller is used to control the conveyor roller to transport the rails and control the transverse lifting device to lift and move the rails.

[0064] The through-beam sensor 1, lift servo motor 29, traverse servo motor 10 in the transverse lift device, and the drive mechanism for rotating the drive rollers in the conveyor rollers are all electrically connected to the controller. Signals from the through-beam sensor 1 are transmitted to the controller, which then controls the transverse servo motor 10 in the transverse mechanism 9 to drive the lift mechanism 5 to move laterally. Furthermore, the controller controls the lift servo motor 29 in the lift mechanism 5 to lift the falling rails, achieving automatic rail transport.

[0065] The automated rail transmission method comprises the following steps:

[0066] S1, the rail is transported to the transverse lifting device through a set of conveyor rollers. The transverse lifting device sends a signal through the beam sensor 1 and receives feedback from the reflector 7, and then sends the received signal to the controller;

[0067] S2. The controller controls the operation of the plurality of transverse mechanisms 9 according to the received signal, and the chain 14 in the transverse mechanism 9 drives the lifting mechanism 5 to move horizontally toward the rail and move to the bottom of the rail;

[0068] S3. When the lifting mechanism 5 moves to the lower end of the rail, the rail positioning sensor 26 in the lifting mechanism 5 is triggered, and the lifting mechanism 5 stops moving. Then, after waiting for all the lifting mechanisms 5 to trigger the rail positioning sensors 26, the controller controls the lifting mechanisms 5 to synchronously lift the rails; all the lifting mechanisms 5 here are all the lifting mechanisms 5 corresponding to the several transverse mechanisms 9 in S2.

[0069] S4. When the rail is lifted to a preset height, the controller controls the transverse movement mechanism 9 to operate, and the chain 14 in the transverse movement mechanism 9 drives the lifting mechanism 5 to move to a preset position on the pad 4. The controller controls the lifting mechanism 5 to synchronously drop the rail and place the rail at the preset position on the pad 4.

[0070] S5. Utilize the traverse mechanism 9 and the lifting mechanism 5 to move from the preset position on the pad 4 to another conveyor roller set in the same manner as in steps S2 to S4 above, thereby achieving automated rail transportation. The other conveyor roller set is different from the conveyor roller set in step S1.

[0071] This device can automatically identify the model of incoming rails and transfer the rails in an orderly manner to the rack storage pad. The stored rail model information will be transmitted to the information library of the controller. When the next process loading is carried out, the rail model information in the information library is read and the corresponding number of horizontal lifting devices are activated to transfer the rails in an orderly manner to the next process loading roller.

[0072] The innovation of this invention lies in the use of transverse lifting equipment to prevent the rail bottom from scratching the rollers and material racks. It also automatically identifies rail specifications without manual assistance, enabling automated rail transportation. This invention offers the advantages of low cost, high precision, simple structure, safety, and reliability, improving production efficiency and reducing worker labor intensity.
