[0025] The present invention will be further described below in conjunction with the drawings and embodiments.

[0026] As Figures 1-9 shown, the multi-directional mobile rail conveying device includes a mounting plate 1 and a fixed mounting frame 2 provided on the mounting plate 1. A conveyor 3, a moving structure 5 for adjusting the position of the conveyor 3 left and right, and a lifting structure 4 for adjusting the position of the moving structure 5 up and down are provided inside the fixed mounting frame 2.

A connecting ear plate 404 for connecting with the output end of the fourth driving member 403 is provided below the support rod 401. A plurality of sprockets 402 for driving the moving structure 5 to move up and down are provided on the support rod 401. A second chain connection seat 505 matching the sprocket 402 is provided on the moving frame 501. A first chain connection seat 204 matching the sprocket 402 is provided on the fixed mounting frame 2. The first chain connection seat 204 and the second chain connection seat 505 are connected by a lifting chain 207 provided on the sprocket 402. Second sliding limit structures are provided on both sides of the support rod 401.

[0029] The fourth driving member 403 adopts a power element that makes a linear motion such as a hydraulic cylinder, a pneumatic cylinder, or an electric cylinder to drive the up and down movement of the support rod 401. By the up and down movement of the support rod 401, the length of the lifting chain 207 between the first chain connection seat 204 and the sprocket 402 and the length of the lifting chain 207 between the second chain connection seat 505 and the sprocket 402 are adjusted, so as to realize the rise or fall of the conveyor 3.

[0030] In the actual use process, the number of the first chain connection seat 204, the second chain connection seat 505, and the sprocket 402 is at least set to two to ensure the stability of the lifting structure 4 during the up and down movement.

[0031] The conveyor 3 is arranged on the moving structure 5, and its position is adjusted left and right by the lateral drive assembly. Then, the position of the moving structure 5 and the conveyor 3 is adjusted up and down by the lifting structure 4, so as to align the position of the conveyor 3 with the rail to be conveyed and ensure the transportation of the rail.

[0032] As Figure 2 shown, the fixed installation frame 2 includes four columns 201 arranged in a rectangular pattern on the mounting plate 1 and four connecting crossbeams 202 arranged on the upper parts of the columns 201 for connecting the columns 201. A fixed crossbeam 203 for installing the first chain connection seat 204 is arranged at the lower part between the left and right columns 201; the basic strength of the fixed installation frame 2 is ensured by the columns 201 and the connecting crossbeams 202, and the fixed crossbeam 203 arranged between the left and right columns 201 can further enhance the strength of the installation frame.

[0033] Track mounting seats 205 are arranged on the opposite sides of the left and right columns 201. Tracks 206 for the first sliding limit structure and the second sliding limit structure to slide are installed on the track mounting seats 205. The first sliding limit structure includes lateral limit guide wheels 508 and longitudinal limit guide wheels 509 arranged on the front and rear sides of the moving frame 501 for sliding on the tracks 206. The second sliding limit structure includes compound guide wheels 405 arranged on both sides of the support rod 401. The longitudinal limit guide wheels 509, the lateral limit guide wheels 508, and the compound guide wheels 405 are all two guide wheels arranged at intervals up and down.

[0034] The lateral limit guide wheels 508 slide on the outer side wall of the track 206 close to the body frame 301. The compound guide wheels 405 and the longitudinal limit guide wheels 509 slide inside the track 206. The longitudinal limit guide wheels 509 are arranged on the front and rear sides of the moving frame 501, facing the front and rear sides. The lateral limit guide wheels 508 are arranged on the inner brackets of the moving frame 501, facing the outside of the moving frame 501. The longitudinal limit guide wheels 509 are installed through an installation frame, and the installation frame is surrounded by four baffles to form a rectangular frame. The installation frame is fixedly connected to the moving frame 501 through vertical plates. The baffles on the left and right sides of the installation frame extend outward for installing the rotating shafts of the longitudinal limit guide wheels 509; the rotating shafts of the lateral limit guide wheels 508 are arranged between two baffles arranged at intervals front and rear, and the two baffles of the lateral limit guide wheels 508 are connected to the moving frame 501 through vertical plates provided with a plurality of reinforcing ribs. The compound guide wheels 405 are arranged on both sides of the support rod 401. When adjusting the position of the conveyor 3 up and down, the compound guide wheels 405 slide above the longitudinal limit guide wheels 509.

[0035] Combined with Figure 4 、 Figure 5 、Figure 6 As shown in the figure, the conveyor 3 includes a body frame 301 disposed on a moving structure 5, support wheels 302 disposed inside the body frame 301 for conveying steel rails, rail conveying pressure arms 303 symmetrically arranged before and after on the support wheels 302, and conveying pressure wheels 304 mounted on the rail conveying pressure arms 303. The rail conveying pressure arms 303 are rotatably connected to the body frame 301, and a first driving member 305 for driving the rail conveying pressure arms 303 to work is arranged on the body frame 301, so that the rail conveying pressure arms 303 drive the conveying pressure wheels 304 to lift or lower. The conveying pressure wheels 304 are arranged on the support wheels 302 in parallel with two rotating wheels of different sizes, and the four rotating wheels are centrally symmetrically arranged with respect to the body frame 301. A second driving member 306 for driving the conveying pressure wheels 304 to rotate is arranged on the body frame 301, and a guiding structure for guiding the direction of the steel rail is arranged outside the feeding end of the support wheel 302.

[0036] The steel rail is conveyed through the support wheels 302 penetratingly arranged inside the body frame 301, and the rail conveying pressure arms 303 and the conveying pressure wheels 304 are arranged on the front side and the rear side of the body frame 301 to provide the frictional force required for the steel rail conveying, and the conveying efficiency of the steel rail is higher; both ends of the rail conveying pressure arms 303 are respectively rotatably connected to the first driving member 305 and the body frame 301, and the first driving member 305 drives the rail conveying pressure arms 303 to rotate around the body frame 301 to realize the lifting and lowering of the conveying pressure wheels 304. When the conveying pressure wheels 304 are lowered, they are in contact with the steel rail, so as to provide the frictional force required for the steel rail conveying. The first driving member 305 can adopt power elements such as hydraulic cylinders, air cylinders, and electric cylinders that perform linear reciprocating motions.

[0037] As Figure 5 shown in the figure, the conveying pressure wheels 304 are arranged on the support wheels 302 in parallel with two rotating wheels of different sizes, and the four rotating wheels are centrally symmetrically arranged with respect to the body frame 301. Two steel rails can be conveyed simultaneously through the two support wheels 302 arranged in parallel. The four rotating wheels are centrally symmetrically arranged with respect to the body frame 301, and the rotating wheels for conveying the left and right steel rails are both one large and one small. When the heights of the two steel rails are inconsistent, both steel rails can be pressed tightly for conveying.

[0038] On the upper right is a large-sized conveying pressure wheel 304, and on the lower right is a small-sized conveying pressure wheel 304. On the upper left is a small-sized conveying pressure wheel 304, and on the lower left is a large-sized conveying pressure wheel 304. When conveying the rail, the front end of the rail moves on the conveyor 3 through a winch. If the height of the upper rail is relatively high or the heights of the two rails are the same, adjust the position of the right rail conveying pressure arm 303 so that the upper rail directly contacts the large-sized conveying pressure wheel 304 on the upper right. The large-sized conveying pressure wheel 304 on the upper right provides frictional force for the conveying of the rail. After the lower rail passes through the small-sized conveying pressure wheel 304 on the lower right, it contacts the large-sized conveying pressure wheel 304 on the lower left, and the large-sized conveying pressure wheel 304 on the lower left provides frictional force for the conveying of the rail. If the height of the lower rail is relatively high, but when the upper rail on the upper right contacts the large-sized conveying pressure wheel 304 and the lower rail does not contact the small-sized conveying pressure wheel 304, then adjust the position of the left rail conveying pressure arm 303 so that the lower rail contacts the large-sized conveying pressure wheel 304 on the lower left. At this time, the small-sized conveying pressure wheel 304 on the left does not contact the upper rail. If the height of the lower rail is relatively high, but when the upper rail on the upper right contacts the large-sized conveying pressure wheel 304 and the lower rail just contacts the small-sized conveying pressure wheel 304 at the same time, at this time, the left rail conveying pressure arm 303 can be lifted to not contact the rail, or it can be lowered to contact both rails. If both rail conveying pressure arms 303 contact the rail, at this time, the heights of both rail conveying pressure arms 303 are the same, and the contact heights of the conveying pressure wheels 304 with the rail are the same, which will not cause excessive pressure on the rail and affect the conveying of the rail, ensuring that at least one conveying pressure wheel 304 contacts the rail during the conveying of the rail to provide frictional force for the conveying of the rail.

[0039] The body frame 301 includes a bottom plate connected to the moving structure 5, two protective plates arranged on the left and right sides of the bottom plate, and a fixing plate fixedly connected to the middle of the two protective plates. The shape of the fixing plate is "door" - shaped. The rail conveying pressure arm 303 is arranged inside the fixing plate. The rail conveying pressure arm 303 is rotationally connected to the fixing plate through a rotating shaft passing through the vertical sections on both sides of the fixing plate. Below the bottom plate, there are guide sleeves 506 and guide nuts 507 for installing the guide optical rods 502 and guide lead screws 503.

[0040] Protective plates are arranged on the left and right sides of the bottom plate to protect the supporting wheels 302, and a "door" - shaped fixing plate is arranged on the protective plate to install the rail conveying pressure arm 303. Thus, the first driving member 305 drives the operation of the rail conveying pressure arm 303 to realize the lifting and lowering of the conveying pressure wheel 304. When the conveying pressure wheel 304 is lowered, it presses on the supporting wheel 302 to provide frictional force for the transportation of the rail.

[0041] When the conveying pressure wheel 304 presses on the rail, the second driving member 306 drives the rotation of the conveying pressure wheel 304, thereby realizing the transportation of the rail. The second driving member 306 can adopt power elements such as motors and motors that perform rotational motion.

[0042] The guiding structure includes two groups of limiting rollers 308 arranged on the front and rear sides of the supporting wheel 302 and two guiding plates 307 arranged at the feeding end of the supporting wheel 302. The number of one group of limiting rollers 308 is two, which are arranged on the left and right sides of the supporting wheel 302. The guiding plates 307 are respectively inclined towards the left and right sides and arranged on the bottom plate to form a "V" shape. The two guiding plates 307 and the bottom plate form a guiding groove.

[0043] By arranging the limiting rollers 308 on the outer side of the rail conveying arm 303, the transportation of the rail is ensured. The limiting rollers 308 are arranged on both sides of the supporting wheel 302 through the limiting shaft. A limiting shaft plate for fixing the position of the limiting shaft is arranged at the upper end of the limiting shaft. Limiting roller protection plates are arranged on the sides of the limiting rollers 308 facing the feeding end and the discharging end of the supporting wheel 302. One end of the guiding plate 307 is connected to the limiting roller protection plate on one side of the feeding end of the supporting wheel 302, and the other end is respectively inclined towards the left and right sides towards the rail to be conveyed. Reinforcing ribs connected to the bottom plate are arranged on the guiding plate 307 to ensure the strength of the guiding plate 307.

[0044] In addition to the above structural forms, the lifting structure 4 also includes the following two structural forms.

[0045] As Figure 7 shown, the structural form of the second lifting structure 4 is: The lifting structure 4 includes two lifting guide columns 406 arranged front and rear on the moving frame 501 and a lifting lead screw 407 arranged between the two lifting guide columns 406. A fifth driving member 408 for driving the rotation of the lifting lead screw 407 is arranged on the fixed installation frame 2. A lifting guide sleeve 409 and a lifting nut 4010 for connecting the lifting guide column 406 and the lifting lead screw 407 are arranged on the moving frame 501.

[0046] The lifting or lowering of the conveyor 3 is driven by connecting the lifting lead screw 407 with the fifth driving member 408. The moving frame 501 rises or falls by the rotation of the lifting lead screw 407 that forms a screw-nut mechanism with the lifting nut 4010. The noise generated during the lifting and lowering process is lower than that of chain drive. Compared with the lubrication and maintenance of the chain, the operating cost is lower. The fifth driving member 408 can adopt power elements such as motors and motors that perform rotational motion.

[0047] The structural form of the third lifting structure 4 is as Figure 8As shown in the figure: The lifting structure 4 includes two lifting guide columns 406 arranged front and back on the moving rack 501 and a sixth driving member 4011 arranged between the two lifting guide columns 406. The output end of the sixth driving member 4011 is connected to the moving rack 501, and a lifting guide sleeve 409 for connecting the lifting guide column 406 is arranged on the outside of the moving rack 501.

[0048] The sixth driving member 4011 is used to directly drive the conveyor 3 to rise or fall, and is positioned and assisted in lifting through the two lifting guide columns 406. During the movement process, the noise is lower than that of the sprocket 402 transmission and the screw-nut mechanism, and the operation and maintenance cost is lower. The sixth driving member 4011 can adopt power components such as hydraulic cylinders, air cylinders, and electric cylinders that perform linear reciprocating motions.

[0049] The lateral driving assembly includes two structural forms, which will be introduced one by one below.

[0050] Combined Figure 3 、 Figure 4 、 Figure 5 As shown in the figure, the first structural form of the lateral driving assembly is: The lateral driving assembly includes a guiding screw rod 503 arranged in the middle of the moving rack 501 and a third driving member 504 arranged on the moving rack 501 for driving the guiding screw rod 503 to rotate. The guiding screw rod 503 and the third driving member 504 form a screw-nut mechanism.

[0051] The guiding optical rod 502 and the guiding screw rod 503 are connected to the machine body frame 301. The third driving member 504 drives the rotation of the guiding screw rod 503, thereby driving the machine body frame 301 to move left and right on the guiding screw rod 503 to realize the position adjustment of the conveyor 3.

[0052] The third driving member 504 can adopt power components such as motors or electric motors that perform rotational motions and be directly connected to the guiding screw rod 503, or the third driving member 504 can be connected to the guiding screw rod 503 by arranging a gearbox 5011, so that the rotation of the guiding screw rod 503 is more stable.

[0053] As Figure 9 shown in the figure, the second structural form of the lateral driving assembly is: The lateral driving assembly includes a seventh driving member 5010 arranged below the moving rack 501 for driving the conveyor 3 to move left and right, and the output end of the seventh driving member 5010 is connected below the conveyor 3.

[0054] The seventh driving member 5010 is arranged on the moving rack 501. The output end of the seventh driving member 5010 is connected to the lower part of the conveyor 3. When the seventh driving member 5010 is started, it directly drives the conveyor 3 to slide on the guiding optical rod 502, thereby adjusting the position of the conveyor 3. This is quieter than the lead screw nut mechanism and has smoother transmission. The seventh driving member 5010 4011 can adopt power elements that perform linear reciprocating motion, such as hydraulic cylinders, pneumatic cylinders, and electric cylinders.

[0055] During the process of the long rail vehicle loading and unloading rails, the height and lateral position of the rails are uncertain. The lifting structure 4 and the moving structure 5 drive the conveyor 3 to move up and down and left and right, so that the position of the conveyor 3 is aligned with the rails to be conveyed, enabling the rails to smoothly enter the conveyor 3. The first driving member 305 on the conveyor 3 drives the rail conveying pressure arm 303 to work, causing the conveying pressure wheel 304 to lift or press the rail, providing the frictional force required for rail conveying. Then, the second driving member 306 drives the conveying pressure wheel 304 to rotate for rail conveying operations. The conveyor 3 can convey two rails at a time and can better adapt to the changes in the rail loading and unloading curves within different ranges, improving the operation efficiency, reducing the length of the rail pulled by the safety vehicle during rail collection, and reducing the safety risks of personnel crossing the vehicle.
