Description

Technical Field

[0001] This application relates to the field of railway maintenance and repair, and in particular to sleeper conveying equipment and operating methods. Background Technology

[0002] Railway sleeper replacement is one of the main tasks in mechanized maintenance of railway lines; sleeper transportation is a necessary procedure in railway sleeper replacement; sleeper transportation refers to transporting old sleepers to sleeper cars or transferring new sleepers from sleeper cars to railway tracks.

[0003] Most existing large-scale sleeper replacement equipment in the industry uses chain or belt conveyor mechanisms, and the sleepers are mostly transported horizontally or at an angle. Chain or belt conveyors have high requirements for longitudinal space along the track, with a length generally exceeding 8 meters. When the height difference is significant, the longitudinal space occupation becomes even more obvious, severely limiting their adaptability to specific working conditions. In addition, chain or belt conveyor mechanisms do not have the function of sleeper clamping and placement. Summary of the Invention

[0004] To address one of the aforementioned technical deficiencies, this application provides a sleeper conveying device and operating method in its embodiments.

[0005] According to a first aspect of the embodiments of this application, a sleeper conveying operation device is provided, comprising:

[0006] frame;

[0007] A suspension mechanism, located at the top of the frame, is used to support sleepers transferred from external equipment and to suspend the sleepers at the top of the frame.

[0008] A sleeper conveying mechanism, mounted on the frame, is movable vertically relative to the suspension mechanism; the sleeper conveying mechanism is used to grip the sleeper suspended on the top of the frame and to transport the sleeper vertically to the ground.

[0009] According to a second aspect of the embodiments of this application, a method for transporting railway sleepers is provided, employing the aforementioned railway sleeper transporting device, comprising the following steps:

[0010] External equipment delivers the sleepers to the suspension mechanism;

[0011] The suspension mechanism suspends the sleepers at the top of the frame;

[0012] The sleeper conveying mechanism rises vertically to the preset position;

[0013] The sleeper conveying mechanism grabs the sleeper that is suspended at the suspension mechanism.

[0014] The sleeper conveying device and method provided in this application have the following advantages:

[0015] This application provides a sleeper conveying device, including a frame, a hovering mechanism, and a sleeper conveying mechanism. According to the solution provided, the sleeper enters the hovering mechanism of the sleeper conveying device and stops at a predetermined position. The sleeper conveying mechanism rises to the predetermined position, clamps the sleeper, and then descends vertically. During the descent of the sleeper conveying mechanism, the next set of sleepers simultaneously enters the hovering mechanism and waits for the next cycle after reaching its position. After the sleeper conveying mechanism reaches its position and releases the sleeper, it begins the next cycle. By setting up the hovering mechanism and the sleeper conveying mechanism, the sleeper entry and vertical sleeper descent actions are completed in parallel, making full use of the cycle time, effectively shortening the time taken for the sleeper descent cycle, and significantly improving operational efficiency and train space utilization.

[0029] To make the technical solutions and advantages of the embodiments of this application clearer, the exemplary embodiments of this application will be described in further detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not an exhaustive list of all embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.

[0030] Figure 1 This is a schematic diagram of the sleeper conveying device for this application; Figure 2 This is a schematic diagram of the hovering mechanism structure in this application; Figure 3 This is a schematic diagram of the sleeper conveying mechanism of this application; Figure 4 This is a schematic diagram showing the connection between the frame and the lifting drive mechanism in this application; Figure 5 This is a schematic diagram of the lifting drive mechanism of this application.

[0031] This application defines the direction of sleeper extension as longitudinal, the direction of sleeper width as transverse, the direction perpendicular to the plane containing the transverse and longitudinal directions as vertical, and the direction of sleeper replacement operation as forward.

[0032] like Figures 1-5 The present application provides a sleeper conveying operation device, which is a vertical sleeper conveying operation device, including a frame 1, a suspension mechanism 2 and a sleeper conveying mechanism 3.

[0033] like Figure 1As shown, frame 1 serves as the main frame, connecting and supporting the suspension mechanism 2, the sleeper conveying mechanism 3, and other mechanisms. The suspension mechanism 2 is located at the top of frame 1, used to carry sleepers transferred from external equipment and to suspend the sleepers on top of frame 1. It is worth noting that the external equipment in this application is a sleeper transport vehicle. The sleeper conveying mechanism 3 is located on frame 1 and can move vertically relative to the suspension mechanism 2; the sleeper conveying mechanism 3 is used to grip the sleepers suspended at the top of frame 1 and to transport the sleepers vertically to the ground.

[0034] The sleeper conveying device provided in this application embodiment moves at a constant speed along the rails with the sleeper transport vehicle. The sleeper conveying device mainly includes a frame 1, a suspension mechanism 2, and a sleeper conveying mechanism 3, and is a vertical sleeper conveying device. During sleeper conveying, the sleeper moves horizontally from the sleeper transport vehicle into the preset position of the suspension mechanism 2 and stops at that point. Then, the sleeper conveying mechanism 3 rises to the predetermined position, clamps the sleeper, and lowers it vertically. During the descent of the sleeper conveying mechanism 3, the next set of sleepers simultaneously enters the suspension mechanism 2 and waits for the next cycle. At the same time, the sleeper conveying mechanism 3 begins the next cycle.

[0035] The sleeper conveying device provided in this application integrates functions such as top sleeper loading, stopping, lowering, and placement, enabling the vertical lowering of multiple sleepers. The device's longitudinal dimension is approximately the length of one sleeper, minimizing its longitudinal space occupation along the track and effectively improving train space utilization and product integration. Through the suspension mechanism 2 and the sleeper conveying mechanism 3, the sleeper loading and vertical lowering actions are completed in parallel, fully utilizing cycle time and effectively shortening the sleeper lowering cycle time, significantly improving operational efficiency.

[0036] like Figures 1 to 2 As shown, the sleeper conveying device provided as a specific embodiment of this application includes a suspension mechanism 2 comprising a suspension frame 201 and a roller 203.

[0037] A suspension frame 201 is disposed on the frame; an idler roller 203 is disposed below the suspension frame 201 and can rotate relative to the horizontal plane; when the idler roller 203 rotates to the lateral direction, it is used to carry the sleepers transferred by external equipment; when the idler roller 203 rotates to the longitudinal direction, it forms a sleeper descent channel extending in the vertical direction.

[0038] Specifically, the suspension mechanism 2 is a suspension platform for sleeper transfer; the idlers 203 are arranged longitudinally at intervals below the suspension frame 201, and multiple idlers 203 form a platform for supporting sleepers; when the sleeper enters, it is temporarily supported by the idlers 203. After the sleeper conveying mechanism 3 moves up to the position, it clamps the sleeper and rotates 90 degrees to make way for the sleeper to descend in the longitudinal direction.

[0039] The embodiments of this application innovatively set up a suspension mechanism 2. By the horizontal rotation of the idler roller 203 of the suspension mechanism 2 and the vertical lifting of the sleeper conveying mechanism 3, the horizontal sleeper entry and sleeper placement are staggered in space, and the sleeper entry and sleeper placement actions are made in parallel, which effectively shortens the cycle time and improves the work efficiency.

[0040] As a specific embodiment of this application, the sleeper conveying device includes a suspension mechanism 2 that also includes a boom 202 and a connecting rod 204.

[0041] The suspension rod 202 is located on the side of the suspension frame 201. The suspension rod 202 extends vertically and rotates about the extension direction of the suspension rod 202 as an axis. The top end of the connecting rod 204 is located at the bottom end of the suspension rod 202 and extends vertically. The bottom end is provided with a downward-opening slot 205. The end of the roller 203 is inserted into the slot 205 to be fixedly connected to the connecting rod 204.

[0042] Specifically, the rotation of the boom 202 along its own axis drives the rotation of the slot 205 at its bottom, further realizing the rotation of the idler roller 203. By rotating the boom 202 90° along its axis, the idler roller 203 changes from a lateral to a longitudinal direction, clearing a path for the sleeper to descend. After the sleeper is clamped by the sleeper conveying mechanism 3, during vertical descent, the idler roller 203 rotates from the longitudinal direction to the lateral direction, returning to its initial position and beginning a new round of sleeper loading. At this time, the sleeper loading and unloading are spatially staggered, achieving parallel actions and effectively shortening the cycle time.

[0043] As a specific embodiment of the sleeper conveying device provided in this application, the suspension mechanism 2 further includes a roller rotation drive mechanism, which is disposed at the top of the boom 202; it is used to provide a driving force for the boom 202 to rotate along the axis, and the boom 202 rotates to drive the roller 203 at the lower end of the boom 202 to rotate.

[0044] As a specific embodiment of this application, the sleeper conveying device includes a roller rotation drive mechanism comprising a gear 206, a longitudinal moving frame 207, a longitudinal guide rail 281, a block 282, and a longitudinal drive member 283.

[0045] Gear 206 is disposed at the top of boom 202; longitudinal moving frame 207 is disposed at the top of suspension frame 201; longitudinal moving frame 207 moves longitudinally relative to suspension frame 201; rack 208 is disposed on the side of longitudinal moving frame 207 facing gear 206, and rack 208 meshes with gear 206.

[0046] Specifically, the longitudinal moving frame 207 moves longitudinally, driving the rack 208 to move longitudinally; through the meshing of the rack 208 and the gear 206, the linear movement of the rack 208 is converted into the rotation of the gear 206, further realizing the rotation of the boom 202 along its own axis.

[0047] It is worth noting that the rotation of the boom 202 can be achieved by a drive motor and a conveyor belt, or by other drive methods to achieve rotation along its own axis.

[0048] As a specific embodiment of the sleeper conveying device provided in this application, the suspension mechanism 2 further includes a longitudinal moving frame drive assembly 208, which includes a longitudinal guide rail 281, a slider 282, and a longitudinal drive member 283.

[0049] The longitudinal guide rail 281 extends in the longitudinal direction; the slider 282 is slidably disposed with the longitudinal guide rail 281; the longitudinal moving frame 207 is connected to the slider 282; the longitudinal drive member 283 is connected to the longitudinal moving frame 207 and is used to provide the driving force for the longitudinal moving frame 207 to move along the longitudinal guide rail 281.

[0050] Specifically, the longitudinal drive component 283 can be a drive component that outputs linear power, such as a drive cylinder, a drive cylinder, or a drive motor; the longitudinal drive component 283 drives the longitudinal moving frame 207 to move along the longitudinal guide rail 281, and further drives the rack 208 of the longitudinal moving frame 207 to move linearly.

[0051] As a specific embodiment of the sleeper conveying device provided in this application, the suspension mechanism 2 also includes positioning components 209, which are disposed at both ends of the suspension frame 201 in the longitudinal direction. When the sleeper is suspended, the positioning components 209 at both ends clamp the sleeper and restrict the sleeper from moving in the longitudinal direction, so as to prevent it from occupying the space of the sleeper conveying mechanism 3 moving in the vertical direction.

[0052] Specifically, the positioning component 209 suspends the sleeper at the top of the frame 1, and clamps the sleeper after the sleeper conveying mechanism 3 moves vertically into position. In operation, the sleeper enters the platform formed by multiple sets of idlers 203 from the sleeper transport vehicle along the rolling direction of the idlers 203. After reaching the preset position, the positioning components at both ends clamp the sleeper and restrict its longitudinal movement, ensuring that the sleeper remains relatively stationary relative to the frame 1. The positioning component 209 is mainly used to lock the sleeper's suspended position, ensuring that the sleeper does not obstruct the upward passage of the sleeper conveying mechanism 3 after it stops.

[0053] As a specific embodiment of this application, the sleeper conveying device includes a positioning component 209 comprising a transverse positioning block 291, a first positioning drive component 292, and a second positioning drive component 293.

[0054] The lateral positioning block 291 extends in the lateral direction; a positioning groove 295 is provided on the side of the lateral positioning block 291 facing the suspension frame 201, and the positioning groove 295 is used to clamp the longitudinal end of the sleeper; a connecting seat 294 is also provided on the upper end of the lateral positioning block 291; one end of the first positioning drive member 292 is hinged to the suspension frame 201, and the other end is movably connected to the connecting seat 294; the second positioning drive member 293 is provided below the first positioning drive member 292; one end is hinged to the suspension frame 201, and the other end is movably connected to the connecting seat 294; a stable triangular frame structure is formed between the second positioning drive member 293, the first positioning drive member 292 and the suspension frame 201.

[0055] In specific implementation, both the first positioning drive component 292 and the second positioning drive component 293 can be telescopic hydraulic cylinders. Alternatively, a drive structure that meets the functional requirements of this invention can be used, such as an electric motor or an internal combustion engine.

[0056] like Figure 1 and Figure 3 As shown, the sleeper conveying device provided as a specific embodiment of this application includes a sleeper conveying mechanism 3 comprising a truss 301 and a sleeper clamping assembly 302.

[0057] Truss 301 is mounted on frame 1 and surrounds the outside of suspension mechanism 2. Truss 301 can move relative to suspension mechanism 2 in the vertical direction. Sleeper clamping assembly 302 is mounted on both longitudinal ends of truss 301 and is used to clamp sleepers mounted on suspension mechanism 2.

[0058] The truss 301 is arranged around the outside of the suspension mechanism 2. The truss 301 moves up and down vertically. At the same time, the roller 203 of the suspension mechanism 2 works with the sleeper transport vehicle to realize the sleeper entry and exit actions. They are spatially staggered and will not interfere with each other.

[0059] Specifically, when the sleeper conveying mechanism 3 drives the truss 301 and the sleeper clamping assembly 302 to the predetermined position, the sleeper is clamped from both ends by the sleeper clamping assembly 302. After the sleeper descends to the predetermined position, the sleeper clamping assembly 302 of the sleeper conveying mechanism 3 releases the sleeper, completing the descent and placement action.

[0060] As a specific embodiment of this application, the sleeper conveying device also includes a lateral movement drive assembly 303. In the curved section operation state, it is used to drive the sleeper clamping assembly 302 to move laterally relative to the truss 301 to compensate for the lateral offset distance between the sleeper and the track.

[0061] Specifically, the sleeper conveying device is vertical. It moves at a constant speed along the rails with the train, while simultaneously performing vertical cyclic movements on a plane perpendicular to the railway track. The sleeper conveying mechanism 3 also has a lateral movement function on the horizontal plane. On straight sections, the sleeper conveying mechanism 3 only requires vertical movement to lower the sleepers. When the train is on curved sections, the sleepers will shift laterally due to the train's core plate distance. In this case, the sleeper conveying mechanism 3 needs to move laterally to compensate for the lateral shift and ensure accurate sleeper placement.

[0062] As a specific embodiment of the sleeper conveying device provided in this application, the lateral movement drive assembly 303 includes a lead screw 331, a lead screw nut 332, and a lateral movement drive member 333. The lead screw 331 extends in the lateral direction and is rotatably connected to the truss 301 at both ends; the lead screw nut 332 is sleeved on the lead screw 331; the sleeper clamping assembly 302 is connected to the lead screw nut 332; the lateral movement drive member 333 is connected to the end of the lead screw 331 and drives the lead screw 331 to rotate, thereby realizing the linear movement of the lead screw nut 332 along the lead screw 331.

[0063] It is worth noting that the lateral drive assembly 303 can also take other forms such as a rack and pinion to achieve the above-described functions. The lateral drive member 333 can therefore be a telescopic hydraulic cylinder. Alternatively, it can be driven by an electric motor or an internal combustion engine that fulfills the functional requirements of this invention.

[0064] As a specific embodiment of the sleeper conveying device provided in this application, the transverse drive assembly 303 also includes a transverse guide rod 334 and a guide sleeve 335.

[0065] The transverse guide rod 334 is arranged parallel to the lead screw 331 and its two ends are connected to the truss 301; the guide sleeve 335 is sleeved on the transverse guide rod 334; the bolster assembly 302 is connected to the guide sleeve 335.

[0066] As a specific embodiment of this application, the sleeper conveying device includes a sleeper clamping assembly 302 comprising a sleeper clamping connecting plate 321, a triangular flipping plate 322, and a sleeper clamping drive component 324.

[0067] A sleeper clamping connecting plate 321 is connected at its top to the lateral movement drive assembly 303; one corner of a triangular flip plate 322 is hinged to the bottom end of the sleeper clamping connecting plate 321; a sleeper clamping plate 323 is connected to one corner of the triangular flip plate 322; and a sleeper clamping drive component 324 is connected at one end to the truss 301 and at the other end to one corner of the triangular flip plate 322. The sleeper clamping connecting plate 321, the triangular flip plate 322, and the sleeper clamping drive component 324 form a hinged flipping structure. The sleeper is clamped by the triangular flip plate 322 driven by the sleeper clamping drive component 324.

[0068] As a specific embodiment of the sleeper conveying device provided in this application, a vertical guide assembly is provided between the frame 1 and the sleeper conveying mechanism 3. The vertical guide assembly includes a vertical guide rail 101 and a guide roller 102.

[0069] A vertical guide rail 101 is mounted on the frame 1 and extends in the vertical direction; a guide roller 102 is mounted on the sleeper conveying mechanism 3 and is slidably mounted with the vertical guide rail 101.

[0070] The vertical guide rail 101 can also be a straight U-shaped rail that achieves the functional requirements of the present invention.

[0071] like Figures 1 to 5 As shown, in specific implementation, the frame 1 is connected to the entire locomotive frame by bolts. The vertical guide rail 101 is fixed to the frame 1 by screws, providing support and guidance for the guide rollers 102 set on the sleeper conveying mechanism 3, ensuring stable posture and smooth movement during the sleeper lifting process.

[0072] like Figures 4 to 5 As shown, in a specific embodiment of this application, the sleeper conveying device is provided with a lifting drive mechanism 103 on the frame 1, which is used to drive the sleeper conveying mechanism 3 to move vertically relative to the suspension mechanism 2; the lifting drive mechanism 103 includes a drive rod 131, a sprocket 132, a chain 133 and a lifting drive component 134.

[0073] The drive rod 131 extends in the lateral direction; both ends of the drive rod 131 are slidably mounted on the frame 1; the frame 1 is provided with a sliding groove 104 for the drive rod 131 to move vertically; the sprocket 132 is mounted on the drive rod 131; one end of the chain 133 is mounted on the bottom of the frame 1, and the other end of the chain 133 is connected to the sleeper conveying mechanism 3 after passing over the sprocket 132; the bottom end of the lifting drive component 134 is connected to the bottom of the frame 1, and the top end is connected to the drive rod 131, and the lifting drive component 134 drives the drive rod 131 to move vertically.

[0074] As a specific embodiment of this application, the lifting drive component 134 adopts a hydraulic cylinder; the hydraulic cylinder, chain 133, and sprocket 132 constitute the lifting power system, which mainly consists of the hydraulic cylinder, which is vertically arranged on the frame 1. The hydraulic cylinder drives the sprocket 132 to drive the chain 133 to rise and fall through the extension and retraction of the hydraulic rod, thereby realizing the lifting and lowering of the sleeper conveying mechanism 3 and the sleepers.

[0075] As a specific embodiment of this application, the frame structure of the provided sleeper conveying device can be made of high-strength steel, which is simple, reliable, and stable in performance. With the support of multiple sets of pulleys, it runs smoothly and stably during operation.

[0076] It is worth noting that the lifting actuator of the lifting drive mechanism 103 uses a hydraulically driven chain to drive the conveying device. Furthermore, the lifting drive mechanism 103 can also employ other types of power sources and actuators, such as steel cables, multi-row chains, or rack and pinion mechanisms, to achieve the same functions.

[0077] Based on the above, the sleeper conveying device provided in this application is a vertical lifting type, with a compact structure and small overall size. The device uses a vertical lifting method for conveying, and compared to an inclined type, to complete the same height conveying, the longitudinal dimension of this device can be reduced by 2.5 to 3 times.

[0078] The sleeper conveying device provided in this application embodiment has a short cycle time and high operating efficiency. During the descent of the sleeper conveying mechanism 3, the sleepers advance longitudinally synchronously. The longitudinal sleeper advance and vertical lifting actions of the device are independent of each other, which can make full use of the cycle time, effectively shorten the cycle time, and thus effectively improve the overall operating efficiency.

[0079] The sleeper conveying device provided in this application embodiment is fully functional and highly adaptable. The device integrates actions such as feeding, stopping, descent, lateral movement, placement, and emergency stop, and can adapt well to various working conditions during construction, effectively handling track conditions such as uphill, downhill, straight, and curved sections.

[0080] As a specific embodiment of this application, a method for transporting railway sleepers is provided, which uses the above-mentioned railway sleeper transporting device and includes the following steps:

[0081] Step (1): The external equipment delivers the sleeper to the suspension mechanism 2;

[0082] Step (2): The suspension mechanism 2 suspends the sleeper at the top of the frame 1;

[0083] Step (3): The sleeper conveying mechanism 3 rises vertically to the preset position;

[0084] Step (4): The sleeper conveying mechanism 3 grabs the sleeper that is suspended in the suspension mechanism 2;

[0085] Step (5): The sleeper conveying mechanism 3 releases the sleepers after descending vertically to the ground.

[0086] The operating method provided by this invention can effectively shorten the time required for sleeper lowering cycles, and significantly improve operating efficiency and train space utilization.

[0087] During operation, the sleeper conveying device moves at a constant speed above the rails along with the train. Sleepers moving horizontally from the front of the train enter the suspension mechanism 2. As the sleeper conveying mechanism 3 descends, the next set of sleepers moving horizontally from the front of the train simultaneously enters the suspension mechanism 2, and waits for the next cycle after reaching their positions. The coordination between the suspension mechanism 2 and the sleeper conveying mechanism 3 allows the horizontal sleeper entry and vertical sleeper placement to be completed in parallel, effectively reducing the cycle time of the entire system and thus improving the system's operational efficiency.

[0088] The sleeper conveying device provided in the specific embodiments of this application is a vertical lifting type, which is the first case of using multiple sleepers for simultaneous vertical lifting with a large drop in the sleeper replacement operation of railway overhaul trains.

[0089] As a specific embodiment of this application, a control unit can also be set up. The control unit mainly collects information such as the speed, acceleration, and position of each actuator, monitors and adjusts the actions of the actuators in real time, so as to achieve coordination and matching with other related devices of the whole machine, thereby ensuring the smooth operation of the system.
