Utility Model Content

[0004] The main purpose of this utility model is to propose a transportation mechanism for track slab production, which aims to reduce the cost of track slab production equipment while improving the production efficiency of track slabs.

[0005] To achieve the above objectives, the present invention proposes a transport mechanism for track slab production, comprising:

[0006] A transport track extends horizontally and is provided with an initial section and a processing section;

[0007] A mobile platform is slidably mounted on the transport track, and a track plate is placed on the mobile platform. The mobile platform is used to drive the track plate to move along the transport track between the initial section and the processing section.

[0008] A lifting mechanism is provided in the processing area and below the track plate. The lifting mechanism is used to lift or lower the track plate in the processing area so that the track plate is separated from or loaded from the mobile platform.

[0009] In one embodiment, the lifting mechanism includes a base, a lifting drive, and a lifting block. The base is disposed in the processing area and has a receiving space inside. The top of the base has an opening. The lifting drive is housed in the receiving space. The lifting block is vertically slidably disposed on the base. The top end of the lifting block extends out of the opening, and the bottom end of the lifting block extends into the receiving space and is connected to the output end of the lifting drive. The lifting drive is used to drive the lifting block to lift or lower, thereby lifting or lowering the track plate in the processing area, so that the track plate is separated from or loaded onto the mobile platform.

[0010] In one embodiment, the opening is rectangular in shape, and the lifting block is rectangular in shape to fit the opening.

[0011] In one embodiment, the lifting mechanism further includes a buffer pad, which is disposed on the top of the lifting block.

[0012] In one embodiment, the lifting mechanism further includes a buffer, and the bottom end of the lifting block is connected to the base through the buffer.

[0013] In one embodiment, the inner wall of the base slides in conjunction with the side wall of the lifting block.

[0014] In one embodiment, the mobile platform includes a mobile frame, a horizontal displacement drive, and rollers. The track plate is placed on the mobile frame, and the mobile frame is mounted on the transport track via the rollers. The output end of the horizontal displacement drive is connected to the mobile frame, and the horizontal displacement drive is used to drive the mobile frame to move the track plate along the transport track between the initial section and the processing section.

[0015] In one embodiment, there are two transport tracks, which are spaced apart. The movable frame includes a connecting rod and two load-bearing rods. The two load-bearing rods are aligned with the extension direction of the transport tracks. Each load-bearing rod is correspondingly installed on the corresponding transport track via a roller.

[0031] As the core component of the ballastless track system for high-speed railways, the manufacturing precision of track slabs directly affects the smoothness of train operation and the service life of the track structure.

[0032] In modern track slab production lines, the transport mechanism plays a crucial role in efficiently transferring track slabs between various processing stations. Traditional transport mechanisms generally employ double locking, requiring simultaneous mechanical locking of both the moving platform and the track slab, resulting in higher equipment costs and lower production efficiency for track slab production.

[0033] To solve this technical problem, this utility model proposes a transportation mechanism for track slab production.

[0034] Please see Figures 1 to 3 In one embodiment of this utility model, the transport mechanism for producing track slabs includes a transport track 100, a moving platform 200, and a lifting mechanism 300. The transport track 100 extends horizontally and is provided with an initial section 101 and a processing section 102. The moving platform 200 is slidably disposed on the transport track 100, and the track slab 10 is placed on the moving platform 200. The moving platform 200 is used to drive the track slab 10 to move along the transport track 100 between the initial section 101 and the processing section 102. The lifting mechanism 300 is disposed in the processing section 102 and is located below the track slab 10. The lifting mechanism 300 is used to lift or lower the track slab 10 in the processing section 102, so that the track slab 10 is separated from or loaded onto the moving platform 200.

[0035] Specifically, the transport track 100 refers to the horizontal guide structure that supports the movement of the mobile platform 200. It can be implemented using I-beam rails or channel rails, and its extension direction corresponds to the production line layout. The mobile platform 200 refers to the transport carrier that supports the track plate 10. It can be implemented using a frame structure with rollers 220, and its reciprocating motion along the track is achieved by a drive device. The lifting mechanism 300 refers to the actuator that realizes the vertical displacement of the track plate 10. It can be implemented using a hydraulic cylinder or an electric push rod structure, and its installation position corresponds to the working area of ​​the processing station.

[0036] More specifically, when the mobile platform 200 transports the track plate 10 to the processing area 102, the lifting mechanism 300 lifts the track plate 10 from its bottom, causing it to detach from the working surface of the mobile platform 200. At this point, the mobile platform 200 can freely return to the initial area 101, exposing the underside of the track plate 10 for further processing (such as smoothing). After processing is completed, the lifting mechanism 300 lowers, causing the track plate 10 to fall back onto the mobile platform 200, completing the transition from the processing area 102 to the transport state. The entire process uses a single lifting action to replace the traditional multi-mechanism coordinated operation, thus fixing the track plate 10 in the processing area 102.

[0037] As an optional implementation, the number of lifting mechanisms 300 is four, and the four lifting mechanisms 300 are distributed at circumferential intervals along the processing area 102.

[0038] Compared to existing technologies, traditional solutions require simultaneous control of the locking device of the mobile platform 200 and the clamping device of the track slab 10, while this solution only requires controlling a single action of the lifting mechanism 300 to complete the positioning. Through this technical solution, this application eliminates the control complexity caused by traditional locking mechanisms, reduces the probability of equipment failure, and improves the production efficiency of the track slab 10. Since the lifting action directly fixes the track slab 10, it avoids multi-mechanism coordination errors, ensures processing and positioning accuracy, and reduces the equipment maintenance point to a single lifting mechanism 300, effectively reducing maintenance costs.

[0039] In the technical solution provided by this utility model, the track plate 10 in the processing area 102 is lifted or lowered by the lifting mechanism 300 to separate it from or load it from the mobile platform 200. The positioning of the track plate 10 in the processing area 102 can be achieved without the need for a complex locking mechanism, which simplifies the production control system of the track plate 10, reduces the equipment failure rate, and improves the production efficiency of the track plate 10.

[0040] Please continue reading. Figure 3 And see Figure 4In an embodiment of this utility model, the lifting mechanism 300 includes a base 310, a lifting drive, and a lifting block 320. The base 310 is disposed in the processing area 102 and has a receiving space. The top of the base 310 has an opening 311. The lifting drive is housed in the receiving space. The lifting block 320 is slidably disposed on the base 310 in a vertical direction. The top end of the lifting block 320 extends out of the opening 311, and the bottom end of the lifting block 320 extends into the receiving space and is connected to the output end of the lifting drive. The lifting drive is used to drive the lifting block 320 to lift or lower the track plate 10 in the processing area 102, so that the track plate 10 is separated from or loaded onto the moving platform 200.

[0041] Specifically, the base 310 refers to the fixed structure that supports the lifting drive component and provides a sliding path for the lifting block 320. It can be implemented by combining a welded steel plate frame with a concrete base, and its accommodating space is used to protect the lifting drive component from external environmental influences. The lifting drive component refers to the device that provides lifting power, which can be implemented by a hydraulic cylinder, electric push rod, or lead screw mechanism, and directly transmits the driving force to the lifting block 320 through a rigid output end. The lifting block 320 refers to the component that contacts the track plate 10 and performs vertical movement. It can be implemented by a rectangular steel block in conjunction with a guide groove. The rectangular structure can increase the contact area to distribute the load on the track plate 10.

[0042] More specifically, after the mobile platform 200 transports the track plate 10 to the processing area 102, the lifting drive unit drives the lifting block 320 to rise vertically along the inner wall of the base 310, causing the track plate 10 to detach from the mobile platform 200 and remain stably suspended in the air. At this time, processing operations such as hole cleaning can be performed. After processing is completed, the lifting block 320 descends to place the track plate 10 back onto the mobile platform 200, completing the loading process. The opening 311 at the top of the base 310 allows the lifting block 320 to extend and retract freely while limiting its horizontal displacement, ensuring positional accuracy during the lifting process.

[0043] This solution replaces the locking function with an integrated lifting mechanism 300, eliminating the need for linkage control between locking devices. The sliding fit structure between the base 310 and the lifting block 320 replaces the snap-fit ​​components of the traditional locking mechanism, reducing the number of mechanical parts. This application utilizes the vertical sliding fit between the lifting block 320 and the base 310 to directly complete the lifting and positioning of the track plate 10, avoiding frequent opening and closing operations of the locking mechanism and simplifying the control system logic. The structure of the lifting drive component built into the housing space of the base 310 reduces the risk of equipment failure caused by external dust intrusion and improves the stability of the mechanism operation. The shape adaptation between the rectangular lifting block 320 and the opening 311 effectively prevents the track plate 10 from horizontally shifting during lifting, ensuring processing positioning accuracy.

[0044] In an embodiment of this utility model, the opening 311 has a rectangular structure, and the lifting block 320 has a rectangular structure adapted to the opening 311.

[0045] Specifically, the opening 311 refers to the opening structure at the top of the base 310, which can be achieved by cutting or welding steel plates to form a rectangular frame structure. Its shape matches the outer contour of the lifting block 320 and is used to limit the horizontal displacement of the lifting block 320. The lifting block 320 refers to a rectangular block corresponding to the shape of the opening 311. It can be made of steel and is inserted into the opening 311 through a sliding fit. It is used to contact the track plate 10 and transmit lifting force during the lifting process. Its rectangular structure can reduce swaying during the lifting process.

[0046] More specifically, when the lifting drive is activated, the lifting block 320 moves vertically within the base 310. The engagement between the rectangular opening 311 and the rectangular lifting block 320 prevents the lifting block 320 from shifting horizontally during movement. The inner wall of the opening 311 forms a sliding contact surface with the side wall of the lifting block 320, thereby constraining the movement trajectory of the lifting block 320 and ensuring that the track plate 10 maintains stable vertical displacement during lifting or lowering.

[0047] This solution utilizes the shape adaptation of a rectangular structure and the sliding engagement between the opening 311 and the lifting block 320 to constrain the motion trajectory, thus avoiding offset issues. This application can eliminate the horizontal displacement error of the track plate 10 during lifting, reduce the adjustment time required for positioning the track plate 10 within the processing range 102, reduce the risk of processing failure due to positional offset, and reduce the frequency of use of the locking mechanism, thereby improving the continuity and stability of the track plate 10 processing steps.

[0048] Please continue reading. Figure 4 In an embodiment of this utility model, the lifting mechanism 300 further includes a buffer pad 330, and the top of the lifting block 320 is provided with a buffer pad 330.

[0049] Specifically, the buffer pad 330 refers to the elastic material layer installed on top of the lifting block 320. It can be made of rubber, polyurethane, or silicone. Its function is to absorb the impact force generated when the track plate 10 comes into contact with the lifting block 320, preventing rigid collisions from damaging the surface of the track plate 10. The elastic deformation characteristics of the buffer pad 330 can disperse local pressure, reduce the transmission of vibration to the lifting drive components, and thus reduce the risk of wear on mechanical parts.

[0050] More specifically, when the lifting block 320 moves upward to lift the track plate 10, the buffer pad 330 first contacts the bottom surface of the track plate 10. During the lifting process, the buffer pad 330 absorbs the inertial impact generated when the moving platform 200 stops through its own elastic deformation, while also buffering the kinetic energy of the track plate 10 falling onto the lifting block 320. Since the buffer pad 330 covers the bearing surface on top of the lifting block 320, the contact area between the track plate 10 and the lifting block 320 is completely isolated by the buffer material, avoiding noise and structural deformation caused by direct collision of metal parts.

[0051] This solution achieves both shock absorption and equipment protection by adding a single buffer layer, eliminating the need for additional shock absorption devices or adjustments to lifting drive parameters. It effectively reduces the mechanical impact on the track slab 10 during lifting or loading, prevents positioning misalignment caused by vibration during processing, reduces fatigue damage to internal parts of the lifting mechanism 300, extends equipment lifespan, and lowers maintenance frequency.

[0052] In an embodiment of this utility model, the lifting mechanism 300 further includes a buffer, and the bottom end of the lifting block 320 is connected to the base 310 through the buffer.

[0053] Specifically, the buffer element refers to the elastic component located between the bottom of the lifting block 320 and the base 310. It can be implemented using springs, rubber pads, or hydraulic dampers, and is used to absorb the impact force generated during the movement of the lifting block 320, reducing damage to the lifting mechanism 300 and the base 310 from rigid collisions. The base 310 refers to the support structure located in the processing area 102, which can be implemented using welded or cast steel plates. It provides a stable mounting base for the lifting mechanism 300 and bears the load transmitted by the lifting block 320.

[0054] More specifically, when the lifting drive unit drives the lifting block 320 to move up and down, the buffer unit forms an elastic connection between the lifting block 320 and the base 310. When the lifting block 320 descends to its lowest position or rises to its highest position, the buffer unit absorbs mechanical impact through its own deformation, preventing hard contact between the lifting block 320 and the base 310. During the lifting or lowering of the track plate 10, the lifting block 320 may vibrate due to changes in the weight of the track plate 10 or the start and stop of the drive unit. The buffer unit offsets the vibration energy through elastic deformation, reducing the wear of the internal parts of the lifting mechanism 300.

[0055] This application effectively mitigates mechanical shock and vibration through the elastic buffering effect of the buffer component, extending the service life of the lifting mechanism 300 while reducing operating noise. It solves the problem of easily damaged parts caused by the lack of buffering measures in the existing lifting mechanism 300, reduces equipment maintenance frequency, and improves the stability and reliability of the track slab 10 transport mechanism during lifting operations within the processing area 102.

[0056] In an embodiment of this utility model, the inner sidewall of the base 310 slides in conjunction with the sidewall of the lifting block 320.

[0057] Specifically, the inner wall of the base 310 refers to the vertical surface inside the base 310 that contacts the lifting block 320. It can be formed by processing metal sheet, and its surface can be coated with a wear-resistant coating to reduce frictional resistance. The sliding fit refers to the formation of a contact-type guide structure between the side wall of the lifting block 320 and the inner wall of the base 310. This can be achieved by combining a linear guide rail and a slider, which limits the horizontal displacement of the lifting block 320 through physical contact.

[0058] More specifically, when the lifting drive unit drives the lifting block 320 to move up and down, the side wall of the lifting block 320 always remains in contact with the inner side wall of the base 310. During the lifting process, the inner side wall of the base 310 constrains the lateral movement of the lifting block 320, allowing the lifting block 320 to move only in the vertical direction. For example, the inner side wall of the base 310 can be provided with a groove structure, and the side wall of the lifting block 320 is embedded in the groove, with the two side walls of the groove and the side wall of the lifting block 320 in clearance fit. Thus, when the track plate 10 is lifted, the sliding fit between the lifting block 320 and the base 310 can eliminate horizontal positional deviations, ensuring the positioning accuracy of the track plate 10 in the processing area 102.

[0059] This solution achieves self-guiding during the lifting process directly through a sliding engagement. In existing technologies, the lifting block 320 is prone to horizontal displacement due to external forces, causing misalignment when the track plate 10 separates from the moving platform 200. This solution actively corrects this displacement through a physical contact guide structure. This application automatically maintains the horizontal stability of the track plate 10 during lifting, avoiding secondary positioning operations caused by displacement of the track plate 10 within the processing area 102. The sliding engagement between the base 310 and the lifting block 320 replaces the function of the traditional locking mechanism, reducing signal interaction nodes in the control system and lowering the risk of downtime due to locking mechanism failure. The mechanical constraint relationship between the lifting block 320 and the base 310 simplifies the positioning process of the track plate 10 and shortens the processing changeover time.

[0060] Please continue reading. Figure 2 and Figure 3 In an embodiment of this utility model, the mobile platform 200 includes a mobile frame 210, a horizontal displacement drive and rollers 220. The track plate 10 is placed on the mobile frame 210, and the mobile frame 210 is mounted on the transport track 100 via the rollers 220. The output end of the horizontal displacement drive is connected to the mobile frame 210, and the horizontal displacement drive is used to drive the mobile frame 210 to move the track plate 10 along the transport track 100 in the initial interval 101 and the processing interval 102.

[0061] Specifically, the movable frame 210 refers to the rigid support structure used to support the track slab 10. It can be implemented using a welded steel frame or an assembled frame. Rollers 220 form a sliding engagement with the transport track 100 to achieve the transfer of the track slab 10 between workstations. The horizontal displacement drive component refers to the device that provides linear power. It can be implemented using an electric actuator, hydraulic cylinder, or servo motor in conjunction with a gear and rack structure, directly acting on the movable frame 210 to control its movement along the track. The rollers 220 are components that enable relative sliding between the movable frame 210 and the transport track 100. They can be steel wheels with bearings or polyurethane-coated wheels, reducing movement resistance through rolling friction.

[0062] More specifically, the movable frame 210 is slidably connected to the transport track 100 via rollers 220. The horizontal displacement drive is fixed to the side or bottom of the track, and its output end is connected to the side or bottom of the movable frame 210 via a rigid connector. When the horizontal displacement drive is activated, the thrust is directly transmitted to the movable frame 210, causing the rollers 220 to roll along the transport track 100, thereby smoothly transporting the track plate 10 from the initial section 101 to the processing section 102. Within the processing section 102, the lifting mechanism 300 lifts the track plate 10 from below, causing it to detach from the movable frame 210.

[0063] This solution utilizes a rigid connection between the moving frame 210 and the rollers 220, combined with direct thrust transmission from the horizontal displacement drive, eliminating the need for a complex locking mechanism. The sliding of the moving frame 210 on the transport track 100 requires only a single drive source, reducing potential points of failure. Automated transport of the track plate 10 between the initial section 101 and the processing section 102 is achieved, avoiding the repeated positioning and locking operations required by traditional locking mechanisms. The cooperative structure between the moving frame 210 and the rollers 220 reduces sliding resistance, and the direct drive of the horizontal displacement drive improves position control accuracy, thereby shortening station changeover time and reducing the risk of downtime due to coordination errors of multiple mechanisms.

[0064] Please continue reading. Figure 2 In this embodiment of the utility model, there are two transport tracks 100, which are spaced apart. The movable frame 210 includes a connecting rod 211 and two load-bearing rods 212. The two load-bearing rods 212 are aligned with the extension direction of the transport tracks 100. The load-bearing rods 212 are arranged in a one-to-one correspondence with the transport tracks 100. Each load-bearing rod 212 is installed on the corresponding transport track 100 through a roller 220. The two load-bearing rods 212 are connected by the connecting rod 211. The output end of the horizontal displacement drive is connected to the connecting rod 211.

[0065] Specifically, the transport track 100 refers to a track structure extending horizontally, which can be implemented using steel rails or concrete tracks, and is used to provide a movement path for the mobile platform 200. The connecting rod 211 refers to a rigid component that laterally connects two load-bearing rods 212, which can be implemented using rectangular steel pipes or I-beams, and is used to maintain the synchronous movement of the two load-bearing rods 212. The load-bearing rod 212 refers to a support structure arranged parallel to the transport track 100, which can be implemented using channel steel or H-beams, and is used to bear the weight of the track slab 10 and distribute the load. The roller 220 refers to a moving component installed at the bottom of the load-bearing rod 212, specifically a steel roller 220 with bearings, used to reduce the frictional resistance between the mobile platform 200 and the transport track 100. The horizontal displacement drive component refers to the power device that drives the mobile frame 210 to move along the transport track 100, which can be implemented using a hydraulic cylinder, electric push rod, or rack and pinion mechanism, and is used to provide stable linear driving force.

[0066] More specifically, the two spaced transport tracks 100, through a split structure, improve the stability of the moving platform 200 and avoid deformation problems caused by uneven load on a single track. The load-bearing rods 212 are arranged one-to-one with the transport tracks 100, ensuring that the rollers 220 of each load-bearing rod 212 roll only along their corresponding tracks, reducing lateral offset during the movement of the track plate 10. The connecting rod 211 rigidly connects the two load-bearing rods 212, ensuring that they move synchronously under the drive of the horizontal displacement actuator, avoiding jamming or track wear due to asynchrony. The output end of the horizontal displacement actuator is directly connected to the connecting rod 211, simplifying the power transmission path through centralized drive and reducing the complexity of multi-drive point coordinated control.

[0067] This solution, through the cooperation of dual tracks and split-type load-bearing rods 212, enhances load-bearing capacity while naturally limiting lateral displacement through the constraint of tracks and rollers 220, eliminating the need for additional guide structures. The rigid connection of connecting rods 211 further strengthens the integrity of the moving frame 210, enabling the horizontal displacement drive component to achieve stable movement with only a single-point drive, simplifying the control logic.

[0068] In an embodiment of this utility model, the mobile platform 200 further includes a riser frame 213, which is mounted on the mobile frame 210, and the track plate 10 is placed on the riser frame 213.

[0069] Specifically, the riser frame 213 refers to the frame structure used to support the track slab 10, which can be realized by a frame structure formed by welding metal rods or profiles, and its height can be adjusted according to the stroke requirements of the lifting mechanism 300. The movable frame 210 refers to the main structure that carries the track slab 10, which can be realized by a steel structure frame with cross-connected horizontal and vertical beams, and forms a sliding fit with the transport track 100 through rollers 220.

[0070] More specifically, after the track plate 10 is moved to the processing area 102, the lifting mechanism 300 lifts the track plate 10 from below, causing it to detach from the riser frame 213. At this point, the track plate 10 is separated from the moving platform 200. Since the track plate 10 is initially placed on the riser frame 213, the initial distance between it and the lifting mechanism 300 is shortened, and the lifting mechanism 300 only needs a small stroke to complete the lifting action. For example, in the hole cleaning process, after the track plate 10 is lifted and fixed by an external clamp, the moving platform 200 can immediately return to the initial area 101 to perform the next transport task without waiting for the lifting mechanism 300 to fully reset.

[0071] Through the above technical solution, this application can reduce the movement range of the lifting mechanism 300, reduce energy consumption during the lifting process, and shorten the time required for the track plate 10 to separate from the mobile platform 200, thereby improving the overall operating efficiency of the transportation mechanism.

[0072] In an embodiment of this utility model, the height-adjusting frame 213 includes two height-adjusting rods 214, both of which are aligned with the extension direction of the transport track 100. The height-adjusting rods 214 are arranged in a one-to-one correspondence with the load-bearing rods 212, and each height-adjusting rod 214 is mounted on the corresponding load-bearing rod 212. The track plate 10 is placed on the two height-adjusting rods 214.

[0073] Specifically, the riser 214 refers to the support structure used to increase the vertical distance between the track plate 10 and the moving frame 210. It can be implemented using rectangular steel beams or channel steel. By arranging it along the extension direction of the transport track 100, the stroke requirement of the lifting mechanism 300 can be reduced, thereby reducing energy consumption.

[0074] More specifically, two lifting rods 214 are fixedly installed on the top of their corresponding load-bearing rods 212, with their extension direction consistent with the transport track 100. The track plate 10 is directly connected to the two lifting rods 214. When the moving platform 200 transports the track plate 10 to the processing area 102, the lifting mechanism 300 only needs to lift the track plate 10 from the top of the lifting rods 214 by a small height to achieve separation, without the need for significant lifting or lowering of the entire moving frame 210. Since the lifting rods 214 and the load-bearing rods 212 are one-to-one and independently set, the overall weight of the moving frame 210 is reduced, while the support stability of the track plate 10 is ensured by the double-rod structure.

[0075] This application, through the use of a split-type lifting rod 214, significantly reduces the load weight of the mobile platform 200 while ensuring stable support for the track slab 10, and simultaneously reduces the range of motion of the lifting mechanism 300, thereby reducing energy consumption and improving response speed. It solves the energy waste problem caused by excessively long lifting strokes in existing technologies, reduces the drive load on the lifting mechanism 300, and avoids the control complexity caused by lifting the entire platform. Furthermore, the split design facilitates maintenance and replacement, further reducing equipment downtime.

[0076] The above description is merely an exemplary embodiment of the present utility model and does not limit the scope of protection of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present utility model.
