Description

Technical Field

[0001] This application relates to the field of sleeper conveying technology, and more specifically, to a ballastless track sleeper conveying structure with a centrally located position. Background Technology

[0002] In the construction and maintenance of ballastless tracks for high-speed railways, sleepers, as key components supporting rails and maintaining track geometry, directly affect the safety and durability of the track system due to their surface cleanliness and structural integrity. With the widespread application of water jet technology in track engineering, using high-pressure water jets to clean, remove adhesive, decontaminate, and micro-roughen the surface of sleepers has become an important process for improving the bonding quality of track structures. This process requires the water jet nozzles to maintain a symmetrical, equidistant, and parallel relative position to the two sides of the sleeper surface to ensure consistent treatment intensity and uniform action on both sides, thereby achieving good surface treatment results. When using ultra-high pressure water jet technology to clean, remove adhesive, remove coatings, or texture railway sleepers, it is necessary to ensure that both sides of the sleeper are parallel and centered with the water jet. If the sleeper is offset, one side will be over-treated while the other side will be under-treated. If they are not parallel, the treatment surface will be uneven, affecting the bonding quality and potentially damaging embedded parts or causing concrete chipping. Current sleeper conveying devices mostly use fixed or simple adjustable support structures, which are difficult to adapt to the rapid positioning requirements of sleepers of different specifications and lack an effective centering adjustment mechanism. This makes it easy for sleepers to have problems such as eccentricity and tilting during the conveying process, making it difficult to meet the process requirements of high-precision water jet treatment. Utility Model Content

[0003] To overcome the above shortcomings, this application provides a ballastless track sleeper conveying position centering structure, which aims to improve the problem that most sleeper conveying devices adopt fixed or simple adjustable support structures, which are difficult to adapt to the rapid positioning requirements of sleepers of different specifications, and lack an effective centering adjustment mechanism, resulting in problems such as eccentricity and tilting of sleepers during the conveying process, making it difficult to meet the process requirements of high-precision water jet processing.

[0004] This application provides a ballastless track sleeper conveying and centering structure, including a conveying structure and an adjusting structure. The conveying structure includes a guide rail, a trolley, and a moving component. The trolley is located on top of the guide rail and is slidably connected to its top. The moving component is disposed on the back of the guide rail. The adjusting structure includes a support frame, a fixing component, and a centering component. The support frame is located in the inner cavity of the trolley, the fixing component is located above the support frame, and the centering component is located in the inner cavity of the support frame.

[0005] In one specific implementation, the moving component includes a support frame, a take-up reel, and a geared motor. The take-up reel is movably connected to the inner cavity of the support frame via a bearing, and the geared motor is fixedly connected to the left side of the support frame by bolts. The output shaft of the geared motor passes through the support frame and is drively connected to the take-up reel.

[0006] In the above implementation process, the support frame is used to support and fix the winding wheel and the reduction motor, thereby improving their stability during use. The reduction motor is used to provide power for the rotation of the winding wheel, and the winding wheel is used to wind up the fixed rope in order to control the trolley to slide back and forth on the top of the guide rail.

[0007] In one specific embodiment, the moving component further includes a fixed rope for moving the trolley and a guide wheel for guiding the fixed rope. The fixed rope is wound around the surface of a take-up wheel, and its two ends are fixedly connected to the front and back of the trolley, respectively. The guide wheel is welded to the front and rear ends of the guide rail surface, and the fixed rope is slidably connected to the surface of the guide wheel.

[0008] In the above process, the fixing rope can pull the trolley to slide back and forth on the top of the guide rail to transport the sleepers. The guide wheel is used to support and guide the fixing rope, change its direction, and reduce the friction it experiences, thereby improving the service life of the fixing rope.

[0009] In one specific implementation, the fixing component includes a fixing frame, a fixing plate, and a fixing rod. The fixing frame is welded to the upper end of the inner cavity of the support frame, the fixing plate is welded to the front and rear ends of the inner cavity of the fixing frame, and the fixing rod is welded to the lower end of the inner cavity of the fixing frame. The inner cavity of the fixing frame, located between the two fixing plates, is welded with reinforcing ribs for enhancing structural stability.

[0010] In the above implementation process, the fixed frame is used to support and fix the internal components, the fixed plate plays a positioning role, the two fixed plates are symmetrical along the center line of the top of the fixed frame so as to play a preliminary positioning role for the two sleepers, and the fixed rod is used to support the sleepers.

[0011] In one specific implementation, the centering component includes a positioning plate, a lifting frame, and a support sleeve. The positioning plate is located at the front and rear ends of the inner cavity of the fixed frame and is slidably connected to the top of the fixed rod. The lifting frame is welded to the top of the positioning plate, and the support sleeve is welded to both sides of the bottom of the two fixed plates.

[0012] In the above implementation process, the two positioning plates are used to position the front and rear sleepers on the side away from the fixed plate. Since the two positioning plates can move synchronously and in opposite directions under the action of the threaded rod, the distance between the front and rear fixed plates and the positioning plates can always be kept consistent, thereby ensuring that sleepers of different specifications can be positioned and that they are in the center position at the top of the support frame. The hoisting frame plays a role in facilitating the hoisting of the support frame so as to carry out the transfer of sleepers.

[0013] In one specific implementation, the centering component further includes a threaded rod, a rotating sleeve, and a positioning pin. The threaded rod is movably connected to the inner cavity of the left support sleeve via a bearing. Its front and rear ends are provided with threads in opposite directions and are threadedly connected to the inner cavities of the two positioning plates, respectively. The surface of the threaded rod is provided with a self-locking structure, and its front and rear ends are movably connected to the inner cavity of the support frame via bearings. The front end of the threaded rod extends through to the front of the support frame. The rotating sleeve is detachably connected to the surface of the threaded rod. The positioning pin is slidably connected to the inner cavity of the right support sleeve. The front and rear ends of the positioning pin respectively penetrate through the two positioning plates and are slidably connected to their inner cavities. The front and rear ends of the positioning pin are fixedly connected to the inner cavity of the support frame.

[0014] In the above implementation process, the support sleeve is used to support the threaded rod and the positioning post. The front and rear ends of the positioning post are provided with threads in opposite directions. Therefore, when the threaded rod rotates, it can drive the two positioning plates to move synchronously and in opposite directions inside the fixed frame, so that the device can be used for sleepers of different specifications, thereby improving the practicality of the device. The rotating sleeve facilitates the rotation of the threaded rod. It has a locking block inside that corresponds to the slot on the right end of the threaded rod. The positioning post provides the positioning effect for the positioning plate.

[0015] In one specific implementation, the centering component further includes a limiting groove and a limiting block for positioning the positioning plate. The limiting groove is formed at the front and rear ends of both sides of the inner cavity of the fixed frame. The limiting block is fixedly connected to both sides of the positioning plate. One side of the limiting block extends into the inner cavity of the limiting groove and is slidably connected to its inner cavity.

[0016] In the above implementation process, the limiting groove and the limiting block work together to limit the positioning plate and prevent its angle from deflecting.

[0017] Compared with the prior art, the beneficial effects of this application are as follows: the conveying structure can drive the sleepers to move inside the water jet device, the sleepers are placed on top of the support frame, and the fixing component and centering component can position sleepers of different specifications to ensure that they are in the center position, so that the water jet device can wash both sides of the sleepers to the same degree, effectively preventing the sleepers from shifting.

The output shaft of the geared motor 1303 passes through the support frame 1301 and is connected to the winding wheel 1302 for transmission. The support frame 1301 is used to support and fix the winding wheel 1302 and the geared motor 1303, improving their stability during use. The geared motor 1303 is used to provide a power source for the rotation of the winding wheel 1302. The winding wheel 1302 is used to wind up the fixed rope 1304 to control the trolley 120 to slide back and forth on the top of the guide rail 110.

The lifting frame 2302 is welded to the top of the positioning plate 2301, and the support sleeve 2303 is welded to both sides of the bottom of the two fixed plates 2202. The two positioning plates 2301 are used to position the front and rear sleepers on the side away from the fixed plate 2202, respectively. Since the two positioning plates 2301 can move synchronously and in opposite directions under the action of the threaded rod 2304, the distance between the front and rear fixed plates 2202 and the positioning plate 2301 can always remain consistent, thereby ensuring that sleepers of different specifications can be positioned and that they are in the center position at the top of the support frame 210. The lifting frame 2302 facilitates the lifting of the support frame 210 for the transfer of sleepers.

[0029] In a specific configuration, the centering component 230 also includes a threaded rod 2304, a rotating sleeve 2305, and a positioning pin 2306. The threaded rod 2304 is movably connected to the inner cavity of the left support sleeve 2303 via bearings. Its front and rear ends are provided with threads in opposite directions, which are threadedly connected to the inner cavities of the two positioning plates 2301, respectively. The surface of the threaded rod 2304 is provided with a self-locking structure, and its front and rear ends are movably connected to the inner cavity of the support frame 210 via bearings. The front end of the threaded rod 2304 extends through the front of the support frame 210. The rotating sleeve 2305 is detachably connected to the surface of the threaded rod 2304. The positioning pin 2306 is slidably connected to the inner cavity of the right support sleeve 2303. The front and rear ends of the positioning pin 2306 respectively extend through the inner cavities of the two positioning plates 2301. Positioning plate 2301 is slidably connected to its inner cavity. The front and rear ends of positioning post 2306 are fixedly connected to the inner cavity of support frame 210. Support sleeve 2303 is used to support threaded rod 2304 and positioning post 2306. The front and rear ends of the surface of positioning post 2306 are provided with threads in opposite directions. Therefore, when threaded rod 2304 rotates, it can drive the two positioning plates 2301 to move synchronously and in opposite directions inside fixed frame 2201, so that the device can be used for sleepers of different specifications, thereby improving the practicality of the device. Rotating sleeve 2305 plays the role of facilitating the rotation of threaded rod 2304. It has a locking block inside that corresponds to the right end slot of threaded rod 2304. Positioning post 2306 plays the role of positioning plate 2301.

[0030] In a specific configuration, the centering component 230 also includes a limiting groove 2307 and a limiting block 2308 for positioning the positioning plate 2301. The limiting groove 2307 is formed at the front and rear ends of both sides of the inner cavity of the fixing frame 2201. The limiting block 2308 is fixedly connected to both sides of the positioning plate 2301. One side of the limiting block 2308 extends into the inner cavity of the limiting groove 2307 and slides in connection with it. The limiting groove 2307 and the limiting block 2308 cooperate to limit the positioning plate 2301 and prevent its angle from deflecting.

[0031] The working principle of the ballastless track sleeper conveying centering structure is as follows: The guide rail 110, trolley 120, and moving assembly 130 are all fixed in a water tank equipped with a water jet device, and the guide rail 110 passes through the interior of the water jet device. When the surface of the sleeper needs to be treated with the water jet device, the position of the two positioning plates 2301 is first adjusted according to the sleeper specifications by rotating the threaded rod 2304 using the rotating sleeve 2305. During the adjustment process, the scale line on the top of the fixing frame 2201 can be referenced to ensure accurate adjustment until the two fixing plates 2201 are aligned. The distance between 02 and positioning plate 2301 matches the length of the sleeper. Then, remove the rotating sleeve 2305 and place the two sleepers between the two fixing plates 2202 and positioning plate 2301 at the front and rear, respectively. After placement, the moving component 130 can be started to drive the trolley 120 to move forward on the top of the guide rail 110. When the trolley 120 passes through the inside of the water jet device, the surface can be treated by high-pressure water flow. After treatment, the support frame 210 and the sleepers can be transported as a whole by connecting the hoisting frame 2302 to the hoisting equipment.
