Description

Technical Field

[0001] This utility model relates to the field of railway vehicle bogie transfer technology, and specifically to a bogie roller transfer device. Background Technology

[0002] In the automated visual inspection of bogies, the bogie is first moved above a pit (with pillars supporting two I-beam tracks). Then, the bogie is moved to the middle of the I-beam track above the pit. Finally, visual inspection is performed by taking photos of the bogie from multiple angles. Furthermore, the ability to capture all points (each object) within the visible range is a crucial indicator for the equipment to complete its inspection task. This necessitates that the camera captures data from multiple angles, including the top, bottom, left, right, front, and rear of the bogie, making it a near-perfect solution.

[0003] Common bogies weigh over 6 tons, and there are few devices that can transport and move the bogies as a whole. They are usually moved within the track by manual labor or traction mechanisms.

[0004] Existing Solution 1: The bogie is manually pushed to the designated position: First, it needs to be pushed manually from the ground; then, personnel enter the pit through a ladder; then, it is pushed horizontally from below the track; after it is manually pushed to the designated position, a limit block is placed to limit it; finally, visual data acquisition is performed.

[0005] The manual operation of this scheme is extremely labor-intensive; during this period, the bogies are often moved one after another on the production line, which can easily cause them to collide with each other and injure the workers; in addition, when pushing the bogies from the ground to the pit, workers are prone to missteps and fall, resulting in accidents such as injuries.

[0006] Existing Solution 2: A horizontal servo slide is arranged at the bottom of the pit along the direction of the bogie passing through the I-beam track, and a synchronous lifting device is installed on the horizontal servo slide. First, the synchronous lifting device simultaneously lifts the four wheels of the bogie to support the entire bogie. Then, under the action of the horizontal servo slide, the bogie is horizontally transported to the designated position. Then, the synchronous lifting device lowers the bogie onto the I-beam track. Finally, visual acquisition is performed.

[0007] This proposed solution uses a synchronous lifting device to lift the bogie as a whole, which causes the bogie to derail from the existing track, reducing safety. It also places high demands on the equipment and consumes a significant amount of energy. Furthermore, it occupies considerable space beneath the bogie, making it difficult to install visual inspection devices and hindering automated visual maintenance operations.

[0008] Existing Option 3: Traction rope traction equipment can only simply drag the bogie forward, cannot stop it precisely, lacks accuracy, can only replace manual pushing of the bogie, and cannot cooperate with automated equipment.

[0009] In summary, the existing bogie transfer methods have the following problems:

[0010] (1) High labor intensity: Manual pushing of bogies is a high-intensity physical labor that is easy to cause fatigue.

[0011] (2) Poor safety: When manual pushing operations are carried out, the production line is busy and people are moving around, which can easily lead to accidents.

[0012] (3) High power: The overall lifting and transport method has a large load, which brings problems such as high power consumption.

[0013] (4) Poor positioning accuracy: Most of them cannot achieve high-precision rapid stop positioning and cannot meet the positioning accuracy requirements.

[0014] (5) Large inertial impact: The bogie has a large mass and the inertia has a large impact on the equipment, which can easily cause unnecessary impact damage to the transport equipment and transported objects.

[0015] (6) Large space occupation: Some existing transfer devices occupy a large space, which restricts the visual shooting space, reduces the number of collection points, and cannot meet the needs. Summary of the Invention

[0016] In view of the shortcomings and deficiencies of the existing technology, the purpose of this utility model is to provide a bogie roller transfer device.

[0017] The technical solution adopted by this utility model to solve its technical problem is:

[0018] A bogie roller transfer device includes a forklift slide and two parallel, overhead tracks. Guide rails and a transmission rack are installed on the inner side of the tracks, and the forklift slide moves along the tracks. The forklift slide includes a slide plate and a power mechanism, a roller support mechanism, and a clamping mechanism mounted on the slide plate. The power mechanism includes a second servo motor, a second servo reducer, and a transmission gear connected in sequence, with the transmission gear meshing with the transmission rack. The clamping mechanism includes a first servo motor, a first servo reducer, a first sprocket, a transmission chain, a second sprocket, a symmetrical trapezoidal nut screw, a small slide plate, and a second ball bearing guide rail connected in sequence. The second ball bearing guide rail is fixed to both sides of the inner wall of the slide plate, and the two small slide plates slide on the second ball bearing guide rail. Two nuts of the symmetrical trapezoidal nut screw are fixed to the opposite sides of the two small slide plates. The screw of the symmetrical trapezoidal nut screw is connected to the second sprocket, and the symmetrical trapezoidal nut screw is fixed to a transmission bracket inside the slide plate. The roller support mechanism is fixed outwards on the small slide plate and is retractable.

[0019] Furthermore, the forklift slide also includes a damping mechanism symmetrically fixed inside the slide plate. The damping mechanism includes a damping bracket, a damper, an adjusting block, a blocking bracket, and a blocking device. A first ball bearing guide is fixed above the inner side of the slide plate, and the bottom of the transmission bracket is fixedly connected to the slider of the first ball bearing guide. A symmetrically arranged middle stop plate is fixed to the side of the transmission bracket. The two sides of the middle stop plate contact the end faces of two blocking devices, and the blocking devices are fixed to the blocking bracket. The back of the blocking bracket is limited and tightened by the adjusting block in conjunction with the screw and nut on the adjusting block, and the bottom of the adjusting block is locked to the damping bracket by the fixing screw. The tail end of the damper is also fixed on the damping bracket, and the rod end of the damper contacts the tail ends on both sides of the middle stop plate.

[0020] Furthermore, the blocker is made of a resetting material.

[0021] Furthermore, the roller support mechanism includes a telescopic shaft, a roller, a guide sleeve, a fixed plate, and a cylinder; a guide sleeve is fixedly provided on the fixed plate, a telescopic shaft is provided inside the first guide sleeve, the inner end of the telescopic shaft is connected to the telescopic end of the cylinder, the stationary end of the cylinder is fixed on the fixed plate, and a roller is provided at the outer end of the telescopic shaft.

[0022] Furthermore, the forklift slide is provided on the inner side of one of the tracks.

[0023] Furthermore, the roller transfer device is equipped with only one fork slide, which only drags one wheel of the transfer bogie.

[0024] Furthermore, a first motor adjustment plate is arranged on the inner side of the slide plate, and a second servo reducer is fixedly arranged on the inner side of the first motor adjustment plate; a first limit block and a second limit block are arranged on both sides of the first motor adjustment plate, and the first limit block and the second limit block adjust and limit the position of the first motor adjustment plate by configuring corresponding screws and nuts.

[0025] Furthermore, the middle of the symmetrical nut trapezoidal screw is fixed in the upper groove of the transmission bracket by the second shaft retaining ring and the second bearing, and the tail end of the symmetrical nut trapezoidal screw is fixed to the extended tail end of the transmission bracket by the first bearing and the first shaft retaining ring. The second sprocket is mounted on the symmetrical nut trapezoidal screw and located inside the first bearing end.

[0026] Furthermore, the first servo reducer is fixed to the transmission bracket by the second motor adjustment plate. The second motor adjustment plate is equipped with a waist-shaped hole to adjust the chain tension. The bottom of the second motor adjustment plate is tightened and locked by screws.

[0027] Furthermore, a drag chain groove bracket is fixed to the bottom inner side of the track, a drag chain groove is fixed on the drag chain groove bracket, a drag chain is placed in the drag chain groove, and the inlet end of the drag chain is connected to the side connection port of the forklift slide.

[0028] Given the challenging issues in existing bogie transportation, the primary consideration is meeting the essential requirement for precise, automated positioning in the later stages. Secondly, for bogies weighing over 6 tons, using a complete lifting and transport method demands high structural stability, inevitably resulting in a bulky transport mechanism, high power consumption, large footprint, and increased design requirements. In this invention, for visual acquisition, space must be allocated to the camera in all directions (front, rear, left, right, up, and down) of the bogie.

[0029] Given the large size and heavy weight of the bogie, a structure of sufficient size is required to ensure basic transportation conditions. After comprehensive consideration, this utility model eliminates one of the I-beam rails and replaces it with a dedicated rail, which can both fulfill the function of a regular rail and serve as the main structure of the bogie conveying device, thus avoiding the occupation of space under the bogie. This combined function saves more space.

[0030] Based on the automation situation, servo-driven transport is the first consideration, and on-rail transport is adopted. The load point for transport is analyzed based on the characteristics of various bogie structural forms (rail spacing of 1435mm, wheel diameter of 840mm and 915mm are common specifications (including some wheel diameters involving changes in wheel manufacturing process)). Since its size is relatively standardized, the deviation is relatively controllable, and the space is relatively easier to intervene in the dragging structure than other positions, the four wheels are the first choice as the dragging object.

[0031] Considering the structural volume, this utility model preferably uses one of the four wheels for traction movement, which can avoid the problem of a large and cumbersome structure for overall transport, while avoiding unnecessary power consumption and the investment in lifting mechanisms due to the large load of overall lifting, and can ensure high positioning accuracy. It is simple and easy to implement.

[0032] The advantages of this bogie support roller transfer device are as follows:

[0033] (1) Reduced labor intensity: It can replace manual pushing of bogies, liberate labor force, and completely release manpower.

[0034] (2) Improved personnel safety: Due to the use of machines, safety is greatly improved.

[0035] (3) Low energy consumption: The non-complete derailment method avoids the overall lifting and transport method in the existing technology. The main energy consumption is the kinetic energy consumption of horizontal movement. The energy consumption is reasonable and the utilization rate is high.

[0036] (4) Ensure high precision: The use of dedicated servo drive can ensure relatively high precision and meet most automation requirements.

[0037] (5) Reduce inertial damage: The servo motor selects a suitable speed reducer and adopts dampers and other mechanisms to reduce inertial damage; at the same time, the bottom-dragging single wheel method of transportation can be used to deal with emergencies. Due to the working characteristics of the bottom of the support wheel, the center of gravity of the wheel is higher than the limit position of the support wheel. After its forward direction is blocked, the impact force will be guided upward, which has excellent unloading ability and outstanding safety protection.

[0038] (6) Small space occupation: Because of the ingenious use of the integrated design of track and conveyor mechanism, the space occupied is very limited, which does not affect the camera to take pictures and collect data from all directions of the bogie, and ensures the acquisition rate to the greatest extent.

Detailed Implementation

[0050] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example 1

[0051] like Figure 1 The diagram shown is a schematic of the bogie roller transfer device in this embodiment for transporting and transferring the bogie 1 on the track. The ordinary I-beam track 2 and the special track 3 are suspended and parallel to each other. The ordinary I-beam track 2 is fixed on the ordinary fixed column 6, and the special track 3 is fixed on the special column 5. (Because the ordinary I-beam track 2 and the special track 3 are different in size and installation method, the two columns are different in size, but both are for more stable support.) The wheel sets on both sides of the bogie 1 fall onto the two side tracks at the same time and can move back and forth.

[0052] The dedicated track 3 includes a dedicated track beam 7, with parallel guide rails 8 arranged along the inner wall of the dedicated track beam 7. A slider is mounted on the upper guide rail 8, which can slide relative to the upper guide rail 8 and is fixed to the bottom of the slide plate 20 of the forklift slide 4. A transmission rack 10 is mounted on the lower guide rail 8, which meshes with the transmission gear 15 of the forklift slide 4 for power transmission. A cable chain groove bracket 13 is fixed to the bottom inner side of the dedicated track beam 7, and a cable chain groove 12 is fixed on the cable chain groove bracket 13. A cable chain 11 is placed in the cable chain groove 12, and the cable chain groove 12 is arranged along the dedicated track beam 7 to support and hold the cable chain 11.

[0053] The forklift slide 4 moves along the dedicated track 3. Two retractable roller mechanisms 14 are mounted on the side of the forklift slide 4. When the forklift slide 4 moves to a position directly below the wheels of the bogie 1 (e.g., ...), ... Figure 2 The roller support mechanism 14 extends out and locks the wheel from both sides.

[0054] like Figure 4 As shown, the forklift slide 4 is equipped with a cover 16 to protect the internal structure and prevent personnel from touching it and causing accidents; signal observation windows 17 are provided on both sides of the cover 16 so that debugging and users can observe the status of the internal magnetic switch signals in a timely manner.

[0055] A cable chain connection port 18 is provided on one side of the cover 16 (a cable chain connection plate 54 is fixed on the side of the slide plate 20, and the cable chain connection plate 54 is connected to the end of the cable chain 11 inlet).

[0056] like Figures 5 to 7 As shown, the forklift slide 4 includes a slide plate 20 and a power mechanism, a roller mechanism 14, a clamping mechanism and a damping mechanism disposed on the slide plate 20. The slide plate 20 is vertically disposed.

[0057] Regarding the power mechanism, such as Figure 6 and Figure 7 As shown, the system includes a first motor adjusting plate 39, a second servo reducer 40, a second servo motor 41, and a transmission gear 15. The first motor adjusting plate 39 is disposed on the inner side of the slide plate 20, and the second servo reducer 40 is fixedly disposed on the inner side of the first motor adjusting plate 39. The input end of the second servo reducer 40 is connected to the second servo motor 41, and the output end of the second servo reducer 40 is connected to the transmission gear 15. The transmission gear 15 meshes with the transmission rack 10 of the dedicated track 3 for power transmission. Preferably, a first limiting block 57 and a second limiting block 58 are provided on both sides of the first motor adjusting plate 39. The first limiting block 57 and the second limiting block 58 can adjust and limit the position of the first motor adjusting plate 39 by configuring corresponding screws and nuts, thereby ensuring that the meshing of the transmission gear 15 and the transmission rack 10 reaches a reasonable contact surface requirement for easy adjustment and preventing changes in the contact surface from affecting the service life.

[0058] Regarding the roller support mechanism 14, such as Figure 5As shown, the mechanism includes a first telescopic shaft 42, a first roller 43, a first guide sleeve 44, a first fixed plate 45, a second fixed plate 49, a second guide sleeve 50, a first cylinder 27, a second cylinder 32, a second roller 55, and a second telescopic shaft 56. Taking one of the roller support mechanisms 14 as an example, the other roller support mechanism 14, which is symmetrical to it, will not be described in detail: A first guide sleeve 44 is fixed on the first fixed plate 45, and a first telescopic shaft 42 is disposed inside the first guide sleeve 44. The inner end of the first telescopic shaft 42 is connected to the telescopic end of the first cylinder 27, and the stationary end of the first cylinder 27 is fixed on the first fixed plate 45. A first roller 43 is disposed at the outer end of the first telescopic shaft 42. The movement of the first cylinder 27 drives the first telescopic shaft 42 inside the first guide sleeve 44 to move forward, and the first roller 43 on the first telescopic shaft 42 extends out. Simultaneously, the second cylinder 32 drives the second telescopic shaft 56 inside the second guide sleeve 50 to move forward, and the second roller 55 on the second telescopic shaft 56 extends out. The two rollers reach below the wheel of the bogie 1 and lift the wheel.

[0059] Regarding clamping mechanisms, such as Figures 5 to 7 As shown, it includes a first servo motor 28, a first servo reducer 29, a first sprocket 48, a transmission chain 31, a second sprocket 67, a symmetrical nut trapezoidal screw 46, a second ball bearing guide rail 51, a first small slide plate 65, and a second small slide plate 66.

[0060] The inner sides of the slide plate 20 are provided with second ball guide rails 51. The second ball guide rails 51 are provided with a first small slide plate 65 or a second small slide plate 66. That is, the first small slide plate 65 and the second small slide plate 66 are located on both sides of the inner side of the slide plate 20, and the first small slide plate 65 or the second small slide plate 66 can slide on the second ball guide rails 51.

[0061] The first small slide plate 65 and the second small slide plate 66 are fixed with a roller support mechanism 14 (specifically, the first guide sleeve 44, the first fixed plate 45 and other structures, and the second guide sleeve 50, the second fixed plate 49 and other structures).

[0062] The other sides (two opposite sides) of the first small slide plate 65 and the second small slide plate 66 are respectively connected to two pairs of nuts of the symmetrical nut trapezoidal screw 46. The middle of the symmetrical nut trapezoidal screw 46 is fixed in the upper groove of the transmission bracket 30 by the second shaft retaining ring 63 and the second bearing 64, and the tail end of the symmetrical nut trapezoidal screw 46 is fixed to the extended tail end of the transmission bracket 30 by the first bearing 60 and the first shaft retaining ring 61. A second sprocket 68 is mounted on the symmetrical trapezoidal screw 46 and located inside the first bearing 60. A transmission chain 31 is mounted on the second sprocket 68, and the other end of the transmission chain 31 is connected to the first sprocket 48. The first sprocket 48 is fixed on the output shaft of the first servo reducer 29. The input end of the first servo reducer 29 is fixed with a first servo motor 28 to realize power output. This ensures that the rotation of the motor screw drives the two sprockets to rotate, which in turn drives the symmetrical trapezoidal screw 46 to rotate, and finally drives the two pairs of nuts on the symmetrical trapezoidal screw 46 to move synchronously and symmetrically. This ensures that the two small slide plates on both sides and the roller support mechanism 14 on the small slide plates move synchronously and symmetrically, thereby realizing the clamping of the wheels of the bogie 1 from both sides.

[0063] Preferably, the first servo reducer 29 is fixed on the transmission bracket 30 by the second motor adjustment plate 62. The second motor adjustment plate 62 is equipped with a waist-shaped hole to adjust the chain tension and ensure normal transmission. The bottom is tightened and limited by screws, and then fixed and locked by screws.

[0064] Regarding damping mechanisms, such as Figure 6 As shown, it includes a first damping bracket 21, a first damper 22, a first adjusting block 23, a first blocking bracket 24, a first blocking device 25, a first ball bearing guide 47, a middle baffle 59, a second blocking device 33, a second blocking bracket 34, a second adjusting block 35, a second damping bracket 36, and a second damper 37.

[0065] like Figure 5 As shown, a first ball bearing guide 47 is fixed above the inner side of the slide plate 20, and the bottom of the transmission bracket 30 is fixedly connected to the slider of the first ball bearing guide 47. Figure 6 and Figure 7 As shown, the transmission bracket 30 has a side-fixed middle baffle plate 59 (the middle baffle plate 59 is symmetrically arranged). The two sides of the middle baffle plate 59 contact the end faces of the first stopper 25 and the second stopper 33. The first stopper 25 and the second stopper 33 are respectively fixed on the first stopper bracket 24 and the second stopper bracket 34. The back of the first stopper bracket 24 and the second stopper bracket 34 are adjusted and limited by the first adjusting block 23 and the second adjusting block 35 in conjunction with the screws and nuts on them. The first adjusting block 23 and the second adjusting block 35 are designed as inverted T-shaped parts, such as... Figure 5As shown, the bottom of the inverted T-shaped part is fixed to the first damping bracket 21 and the second damping bracket 36 by two fixing screws respectively; a horizontal screw is installed in the middle of the inverted T-shaped part, and the position of the screw can be adjusted back and forth to tighten the first blocking bracket 24 and the second blocking bracket 34 to adjust and prevent displacement. The tail ends of the first damper 22 and the second damper 37 are also fixed to the first damping bracket 21 and the second damping bracket 36 respectively. The rod ends of the first damper 22 and the second damper 37 contact the tail ends on both sides of the middle baffle 59. When the slider of the first ball guide rail 47 swings left and right due to inertia, the kinetic energy will be transferred to the dampers (first damper 22 and second damper 37) to consume the inertial kinetic energy. And when it hits the blocker (first blocker 25 and second blocker 33), because the blocker is made of a reset material (high elastic material, such as rubber, spring, etc.), it will return to the center position.

[0066] In addition, the ends of the first damping bracket 21 and the second damping bracket 36 are fixed with the first alarm light bracket and the second alarm light bracket 53, on which the first running alarm light 26 and the second running alarm light 52 are mounted. Example 2

[0067] The method of using the bogie roller transfer device in this embodiment is as follows:

[0068] When the first servo motor 28 drives the symmetrical nut trapezoidal screw 46 to rotate through the intermediate transmission structure (first servo reducer 29, two sprockets, transmission chain 31), the two nuts on the symmetrical nut trapezoidal screw 46 respectively drive the first small slide plate 65 and the second small slide plate 66 to run symmetrically.

[0069] The first telescopic shaft 42 and the second telescopic shaft 56 on the first small slide plate 65 and the second small slide plate 66 extend to clamp the wheel flange position; due to the use of a trapezoidal screw, the clamping mechanism is in a self-locking state to ensure the safety and reliability of the clamping.

[0070] The second servo motor 41 runs, driving the transmission gear 15 to rotate, realizing gear and rack (transmission rack 10) transmission, and driving the bogie 1 to the designated position;

[0071] Because the bogie 1 is relatively heavy, it has a large inertia at the moment of starting. The overall mechanism on the transmission bracket 30 transmits kinetic energy through the middle baffle 59 to the first damper 2 and the second damper 37 fixed on the slide plate 20 and the first stopper 25 and the second stopper 33. When the inertia disappears, the first stopper 25 and the second stopper 33 will reset, ensuring that the transmission bracket 30 returns to its original position on the first ball guide rail 47. When stopping, the inertial kinetic energy is also consumed, ensuring that the structure is not subjected to large impact forces and that the equipment operates stably and reliably.

[0072] The above description is merely a preferred embodiment of the present utility model and does not constitute a limitation on the scope of protection of the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the scope of protection of the claims of the present utility model.
