In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0023] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting" should be understood in a broad sense, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0024] The specific embodiments of the present application are described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application, and are not used to limit the present application.

[0025] The embodiments of the first aspect of the present application provide a track plate conveying device, as shown in Figure 1 and Figure 2 The track plate conveying device comprises an end limiting frame 1 and a middle limiting frame 2, the middle limiting frame 2 is arranged opposite to the end limiting frame 1 along the X direction, a limiting cavity 3 for limiting the material 4 along the X direction and the Y direction is formed between the middle limiting frame 2 and the end limiting frame 1, and the end limiting frame 1 and the middle limiting frame 2 are used to be connected with the track conveying vehicle 5.

[0026] It can be understood that the X direction is perpendicular to the Y direction, and both the X direction and the Y direction are parallel to the horizontal plane.

[0027] In use, the end limiting frame 1 and the middle limiting frame 2 are connected with the track conveying vehicle 5, and then the track plates are stacked in the limiting cavity 3. During the conveying process, the limiting cavity 3 can limit the position of each track plate along the X direction and the Y direction, so as to avoid the track plate from falling off the track conveying vehicle 5.

[0028] Compared with the prior art, the track plate conveying device provided by the above-mentioned embodiments can stably limit the track plate in the limiting cavity 3, realize the conveying of the track plate by the track conveying vehicle 5, and has higher conveying efficiency than the truck transportation, solves the problems of over-limit and over-weight, and can reduce the management cost and safety risk in the track plate conveying process.

[0029] In an optional embodiment, a guide section is arranged at the top end of the limiting cavity 3, and the guide section is designed as follows: in the Z direction (i.e. the vertical direction), when extending from the end close to the track conveying vehicle 5 to the direction away from the track conveying vehicle 5, the opening size of the guide section gradually increases. The guide section can be formed by the upper structure of the end limiting frame 1 and the middle limiting frame 2, and the longitudinal section shape thereof is preferably a horn-shaped or tapered expanding structure.

[0030] It can be understood that the longitudinal section is a plane perpendicular to the horizontal plane.

[0031] Through the above structural design, when the track plate is loaded into the limiting cavity 3 from the top, the guide section can provide a larger inlet in the vertical direction, thereby guiding the track plate to smoothly enter the inside of the limiting cavity 3, avoiding excessive collision with the end limiting frame 1 and the middle limiting frame 2 due to deviation of the hoisting position of the track plate, and facilitating rapid stacking of the track plate in the limiting cavity 3.

[0032] The specific structure of the guide section will be specifically described in the detailed description of the end limiting frame 1 and the middle limiting frame 2 below.

[0033] The structure of the end limiting frame 1 will be specifically described below: In an optional embodiment, as shown in Figure 1 and Figure 2 , the end limiting frame 1 includes a seat frame 11, a blocking frame 12, and a diagonal brace 13, wherein the seat frame 11 serves as a basic structure for connecting the end limiting frame 1 to the track transport vehicle 5, for stably installing the entire end limiting frame 1 on the track transport vehicle 5, and ensuring the stability and safety of the structure during transportation.

[0034] In addition, the blocking frame 12 is connected perpendicularly to the seat frame 11, specifically, one end of the blocking frame 12 is fixedly connected to one end of the seat frame 11 close to the middle limiting frame 2, and the other end extends upward, and the blocking frame 12 and the middle limiting frame 2 form a limiting cavity 3 for accommodating and limiting the track plate.

[0035] In order to enhance the structural strength of the connection between the blocking frame 12 and the seat frame 11, and improve the anti-deformation ability of the end limiting frame 1 during transportation, as shown in Figure 2 and Figure 3 , the end limiting frame 1 can further include a diagonal brace 13. One end of the diagonal brace 13 is connected to the seat frame 11, and the other end is connected to the blocking frame 12, and the diagonal brace 13 forms a non-right-angle inclined connection structure with the seat frame 11 and the blocking frame 12, thereby forming a triangular support system, effectively improving the rigidity and stability of the overall structure.

[0036] The above-mentioned end limiting frame 1 is designed to be composed of the seat frame 11, the blocking frame 12, and the diagonal brace 13, which not only realizes reliable connection with the track transport vehicle 5, but also forms a limiting cavity 3 for stably bearing the track plate through cooperation between the blocking frame 12 and the middle limiting frame 2, and improves the stability and bearing capacity of the overall structure through the setting of the diagonal brace 13, thereby effectively guaranteeing the safety and reliability of the track plate during transportation.

[0037] The seat frame 11 can be connected to the bottom plate of the track transport vehicle 5 in various ways, such as through bolt connection, clamping, etc. In an optional embodiment, the seat frame 11 is clamped with a limiting piece on the track transport vehicle 5, for example, the bottom plate of the track transport vehicle 5 is fixedly provided with a hawk lock, as shown in Figure 4 The bottom of the seat frame 11 is provided with a first limiting hole 1111 clamped with the hawk lock.

[0038] Specifically, as shown in Figure 4 The bottom of the seat frame 11 is provided with a plurality of first limiting holes 1111 for clamping with the hawk lock on the track transport vehicle along the X direction. This structure is designed to realize the detachable connection between the seat frame 11 and the track transport vehicle, thereby improving the assembly efficiency and stability between the track plate transport device and the track transport vehicle.

[0039] Specifically, the first limiting hole 1111 is arranged in two rows, and the two rows of first limiting holes 1111 are oppositely arranged along the Y direction. In each row of first limiting holes 1111, each first limiting hole 1111 is spaced apart along the X direction, and the arrangement pitch is adapted according to the length of different models of track plates to meet the transportation needs of track plates of different lengths. In each row of first limiting holes 1111, the appropriate first limiting hole 1111 is selected to be inserted and matched with the hawk lock, so as to realize the fixation of the seat frame 11 and the track transport vehicle 5 in the horizontal direction, thereby preventing the displacement or falling of the end limiting frame 1 due to vibration or impact during transportation.

[0040] Further, the first limiting hole 1111 is a through hole structure, and its shape can be circular, elliptical, waist-shaped or polygonal, and the specific shape is matched according to the structure of the limiting piece to be matched.

[0041] In an optional embodiment, as shown in Figure 2 The seat frame 11 includes a frame body 111 and a cover plate 112, the bottom of the frame body 111 is provided with a first limiting hole 1111 for connecting with the track transport vehicle 5, and the cover plate 112 is rotationally matched with the top of the frame body 111 and forms a containing cavity between the frame body 111, which is used to accommodate the cushion block 6 between the materials 4.

[0042] During transportation, in order to avoid damage to the upper and lower two layers of materials 4 due to direct contact, a cushion block 6 is usually placed between the materials 4, and the cushion block 6 is separated from the track plate. When transported to the designated location, in order to facilitate the recycling of the cushion block 6, the operator can open the cover plate 112 to orderly place the cushion block 6 in the containing cavity for storage, and then close the cover plate 112, waiting for the next use.

[0043] The cover plate 112 is rotatably connected to the top of the frame 111 via a pivot or hinge structure, allowing the cover plate 112 to be flipped open or closed relative to the frame 111. When the cover plate 112 is closed, it forms a closed or semi-closed receiving cavity with the frame 111. This receiving cavity is used to accommodate the pads 6 between the track plates. The pads 6 are usually made of wood or plastic and provide a certain cushioning effect.

[0044] The edge of the cover plate 112 may be provided with a handle to facilitate the opening and closing of the cover plate 112 by the operator. The cover plate 112 may be fixed by a latch, snap or other locking structure to prevent the cover plate 112 from being accidentally opened due to vibration or impact, thereby ensuring the stable storage of the pad block 6.

[0045] In an optional embodiment, the main body of the frame 111 is a rectangular frame structure, which includes a first longitudinal beam extending along the X direction and a first transverse beam extending along the Y direction, and may also include reinforcing ribs connecting the first longitudinal beam and the first transverse beam.

[0046] The first horizontal beam and the first vertical beam can be made of plate structure, or the cross-section can be in the shape of "I", "L", "T", "U" or ring, etc. The beams can be connected by welding, bolts or other methods. The specific structural form and connection method of the first horizontal beam and the first vertical beam can be selected according to actual needs.

[0047] like Figure 2 As shown, the bottom end of the diagonal brace 13 is detachably connected to the middle of the rectangular frame structure along the X direction. The detachable connection can be made by bolt connection, snap-fit, etc.

[0048] like Figure 5 As shown, the frame 111 has an insertion slot 1112 at one end near the middle baffle 22 along the X direction. The bottom end of the baffle 12 can be inserted into the insertion slot 1112 and locked by bolts or other connecting parts to ensure the stability of the connection between the baffle 12 and the frame 111.

[0049] like Figure 5 As shown, the top of the rectangular frame structure can also be connected to a hoisting frame 113 that protrudes along the Y direction from both sides of the rectangular frame structure. The hoisting frame 113 is equipped with a hook 1131. The hoisting equipment can hoist the seat frame 11 through the hook 1131, so that when the end limit frame 1 is not used, the stop frame 12 and the diagonal brace 13 can be removed, and each frame 111 can be hoisted and stacked from bottom to top.

[0050] In alternative implementations, such as Figure 3As shown, the blocking frame 12 includes a first transverse blocking frame 122 and two first longitudinal blocking frames 123, the bottom end of the first transverse blocking frame 122 is inserted into the insertion slot 1112, and the two first longitudinal blocking frames 123 are oppositely arranged along the Y direction on both sides of the first transverse blocking frame 122, and the two first longitudinal blocking frames 123 are both connected perpendicularly to the first transverse blocking frame 122 to form a semi-enclosed U-shaped frame structure with the first transverse blocking frame 122.

[0051] In use, the first transverse blocking frame 122 can limit the position of the track plate along the X direction, and the two first longitudinal blocking frames 123 can limit the position of the track plate along the Y direction, in order to ensure the connection firmness between the three, a reinforcing rib can be arranged between the first transverse blocking frame 122 and the first longitudinal blocking frame 123, thereby increasing the ability of the first longitudinal blocking frame 123 to resist impact from the track plate.

[0052] As shown, Figure 3 the inner side of the top end of the first transverse blocking frame 122 is provided with a first inclined surface 1221, and the inner side of the top end of the two first longitudinal blocking frames 123 is provided with a second inclined surface 1231, the first inclined surface 1221 is arranged in a direction gradually away from the track transport vehicle 5 in the Z direction and inclined to the direction away from the middle limiting frame 2, and the two second inclined surfaces 1231 gradually increase in distance in the Z direction along the direction gradually away from the track transport vehicle 5, thereby forming part of the guiding section of the limiting cavity 3, facilitating the rapid stacking of the track plates.

[0053] In an optional embodiment, in order to further improve the stability and safety of the track plate during transportation and prevent rigid contact between the track plate and the end limiting frame 1, which can cause surface damage or wear, Figure 3 As shown,

[0054] the surfaces of the first transverse blocking frame 122 and the two first longitudinal blocking frames 123 forming the limiting cavity 3 are provided with first buffer pads 121.

[0055] The first buffer pad 121 can be made of a material with elasticity and wear resistance, such as but not limited to flexible materials such as rubber, polyurethane, or silicone. The first buffer pad 121 can be firmly installed on the inner side surface of the first transverse blocking frame 122 and the first longitudinal blocking frame 123 by means of adhesion, screw fixation, buckle connection, etc., to ensure that it will not fall off or shift during transportation.

[0056] Specifically, on the first transverse stop 122, the first buffer pad 121 is configured as a plurality of, and the plurality of first buffer pads 121 are distributed along the Y direction at equal intervals; on the two first longitudinal stops 123, according to the length of the first longitudinal stop 123 in the X direction, the first buffer pad 121 can be configured as one or a plurality of, and together with the first buffer pad 121 on the first transverse stop 122, it forms a limiting area that matches the shape of the track plate.

[0057] In addition, as shown in Figure 3 , the surface of the frame body 111 facing the middle limiting frame 2 is also provided with a first buffer pad 121, which is in the form of a strip and extends along the Y direction. The first buffer pad 121 is located at the bottom of the limiting cavity 3 and can buffer the lowest track plate.

[0058] The structure of the middle limiting frame 2 will be described in detail below. As shown in Figure 1 , one side of the middle limiting frame 2 along the X direction forms a limiting cavity 3 with the end limiting frame 1 at the tail end, and the other side of the middle limiting frame 2 along the X direction forms a limiting cavity 3 with the end limiting frame 1 at the head end, so as to make full use of the structure of the two sides of the middle limiting frame 2 for limiting and improve the single transportation capacity of the track plate.

[0059] In an optional embodiment, as shown in Figure 6 and Figure 7 , the middle limiting frame 2 includes a base 21, an intermediate stop 22 and a support frame 23, which are used to cooperate with the end limiting frame 1 to form a limiting cavity 3 and realize stable transportation of the track plate through connection with the track transport vehicle 5.

[0060] Specifically, the base 21 serves as the connecting basic structure between the middle limiting frame 2 and the track transport vehicle 5, which is arranged on the bottom plate of the track transport vehicle 5 and fixed to the track transport vehicle 5 through a detachable connection mode (such as bolt connection, clamping or welding, etc.), to ensure the structural stability and safety of the entire middle limiting frame 2 during transportation.

[0061] As shown in Figure 7 , the bottom of the base 21 is provided with a plurality of second limiting holes 211 for clamping with the hawk hook on the track transport vehicle 5 along the X direction.

[0062] Specifically, the second limiting holes 211 are configured in two rows, with the two rows of second limiting holes 211 arranged opposite each other along the Y direction. Within each row, the second limiting holes 211 are spaced apart along the X direction, and their spacing is adapted to the length of different types of track slabs to meet the transportation needs of track slabs of varying lengths. By selecting appropriate second limiting holes 211 in each row and engaging them with hook locks, the base 21 and the track transport vehicle 5 can be fixed in the horizontal direction, thereby preventing the central limiting frame 2 from shifting or falling off during transportation due to vibration or impact.

[0063] Furthermore, the second limiting hole 211 is a through hole structure, and its shape can be circular, elliptical, waist-shaped or polygonal. The specific shape is designed to match the structure of the limiting component it is used with.

[0064] In alternative implementations, such as Figure 7 As shown, the main body of the base 21 has a rectangular frame structure. The rectangular frame structure includes a second longitudinal beam extending along the X direction and a second transverse beam extending along the Y direction. It may also include reinforcing ribs connecting the second longitudinal beam and the second transverse beam.

[0065] The aforementioned second horizontal beam and second vertical beam can be made of plate structure, or can be made of structure with cross-section in the shape of "I", "L", "T", "U" or ring, etc. The beams can be connected by welding, bolts or other methods. The specific structural form and connection method of the second horizontal beam and second vertical beam can be selected according to actual needs.

[0066] The intermediate baffle 22 is vertically connected to the base 21. The intermediate baffle 22 extends in the vertical direction and its height is adapted to the height requirements after the track plates are stacked. It is set opposite to the end limiting frame 1 in the X direction. The two together define the limiting cavity 3 for accommodating the track plates in the X and Y directions.

[0067] Specifically, such as Figure 6 As shown, the intermediate support frame 22 includes a vertical beam 222, a third crossbeam 223, and a side plate 224; the third crossbeam 223 extends along the Y direction and is configured with two beams that are arranged opposite each other along the Z direction, one of which is connected to the base 21; the side plate 224 is configured with two beams, which are arranged opposite each other along the Y direction and are both connected to the base 21 at the bottom, one of which is fixedly connected to one end of the two third crossbeams 223, and the other is fixedly connected to one end of the other two third crossbeams 223; the vertical beam 222 is configured with two beams, which extend along the Z direction and are connected at both ends to the two third crossbeams 223 respectively.

[0068] Of course, the aforementioned third horizontal beam 223 and vertical beam 222 can also be configured as three, four, five or even more.

[0069] The above arrangement makes the intermediate retaining frame 22 have good structural stability and carrying capacity, and can cooperate with the end retaining frame 1 to jointly form the limiting cavity 3 for accommodating and limiting the track plate.

[0070] The top end of the upper third cross beam 223 has a third inclined surface 2231 in the X direction, and the inner side of the top end of each side plate 224 has a fourth inclined surface 2242. The distance between the two third inclined surfaces 2231 in the Z direction gradually decreases in the direction gradually away from the track transport vehicle 5, and the distance between the two fourth inclined surfaces 2242 in the Z direction gradually increases in the direction gradually away from the track transport vehicle 5, thereby forming a partial guide section of the limiting cavity 3, facilitating the rapid stacking of the track plates.

[0071] In order to further improve the stability and safety of the track plate during transportation, prevent rigid contact between the track plate and the end retaining frame 1, and cause surface damage or wear, as shown in Figure 6 The vertical beam 222 and the side plate 224 form a surface of the limiting cavity 3 provided with a second buffer pad 221.

[0072] The second buffer pad 221 can be made of a material with elasticity and wear resistance, such as but not limited to flexible materials such as rubber, polyurethane, or silicone. The second buffer pad 221 can be firmly installed on the inner side surface of the vertical beam 222 and the side plate 224 by adhesion, screw fixation, buckle connection, etc., to ensure that it will not fall off or shift during transportation.

[0073] The above-mentioned second buffer pad 221 is in a strip shape and extends from top to bottom. The extension path of the second buffer pad 221 can match the inner profile of the vertical beam 222, the third cross beam 223 and the side plate 224. For example, when the third cross beam 223 is provided with a third inclined surface 2231 and the two side plates 224 are provided with a fourth inclined surface 2242, the top end of the second buffer pad 221 can fit the third inclined surface 2231 and the fourth inclined surface 2242.

[0074] Specifically, one second buffer pad 221 is installed on each vertical beam 222, the top end of the second buffer pad 221 extends to the upper third cross beam 223, and the bottom end of the second buffer pad 221 extends to the lower third cross beam 223. On the two side plates 224, the portion of the side plate 224 on the side of the third cross beam 223 in the X direction is provided with at least one second buffer pad 221, and the portion on the other side of the third cross beam 223 in the X direction is provided with at least one second buffer pad 221, which together with the second buffer pad 221 on the vertical beam 222 encloses a limiting area matching the shape of the track plates on both sides.

[0075] In addition, in order to facilitate the operator to observe the relative position between the track plate and the vertical beam 222 and the relative position between the track plates before transportation, prevent unstable transportation caused by track plate deviation or inclination, such as Figure 6 As shown in the side plate 224, an observation hole 2241 is formed.

[0076] The observation hole 2241 is preferably a circular or rectangular through hole, and the observation hole 2241 can be configured as multiple, multiple observation holes 2241 are equally spaced along the Z direction, and located in the opposite direction of the gap region between the track plate and the vertical beam 222. The size of the observation hole 2241 is designed to allow the operator to clearly observe the relative distance between the track plate and the vertical beam 222 visually.

[0077] Further, the support frame 23 is fixedly connected with the intermediate blocking frame 22 and is arranged on both sides of the intermediate blocking frame 22 along the X direction. The arrangement of the support frame 23 not only enhances the overall structural strength of the intermediate blocking frame 22, but also plays a role in assisting the limiting of the track plate in the X direction.

[0078] In addition, the connection mode between the support frame 23 and the intermediate blocking frame 22 can be welding, bolt connection or one-piece structure, which is selected according to the manufacturing process and transportation strength requirement.

[0079] In summary, through the cooperation of the base 21, the intermediate blocking frame 22 and the support frame 23, the middle limiting frame 2 can be stably connected with the track transport vehicle 5, and together with the end limiting frame 1 to build a limiting cavity 3 with limiting function in the X direction and the Y direction, thereby realizing efficient and safe transportation of the track plate, improving transportation efficiency, and reducing safety risk and management cost in the transportation process.

[0080] In an optional embodiment, as shown in Figure 6 The middle limiting frame 2 further comprises a clamping plate 24 connected with the support frame 23, and the clamping plate 24 is bent to form a first limiting groove 25 for cooperating with the track transport vehicle 5 and limiting the position of the support frame 23 relative to the track transport vehicle 5 along the Y direction.

[0081] When the clamping plate 24 is installed on the support frame 23, the first limiting groove 25 can be clamped with the bottom plate of the track transport vehicle 5, thereby limiting the middle limiting frame 2 in the Y direction, preventing it from deviating or shaking in the transportation process, and ensuring the stability of the entire middle limiting frame 2 on the track transport vehicle 5.

[0082] The clamping plate 24 is bent to be approximately "L" shaped or "U" shaped, specifically, as shown in Figure 6As shown, the clamping plate 24 is bent into an approximate "U" shape, and the top end of the clamping plate 24 is fixed between the support frame 23 by means of bolts or welding, etc., to ensure the strength and reliability of the connection. The side edge extends downward from the side of the bottom plate of the rail transport vehicle 5, and the bottom end abuts against the bottom surface of the bottom plate or is connected to the bottom plate by means of bolts, etc.

[0083] Through the design of the above-mentioned embodiments, not only the connection stability between the middle limiting frame 2 and the rail transport vehicle 5 is enhanced, but also the safety and reliability of the entire rail plate transport device during transportation are effectively improved, and the transportation risk is reduced.

[0084] In an optional embodiment, the rail plate transport device further comprises a bearing frame 7 located at the bottom of the limiting cavity 3 and used for bearing the rail plates, so as to avoid the direct contact of the bottommost rail plate with the rail transport vehicle 5 and protect the bottommost rail plate.

[0085] The bearing frame 7 has a second limiting groove 71 cooperating with the rail transport vehicle 5 and defining the position of the bearing frame 7 relative to the rail transport vehicle 5 along the Y direction. When the bearing frame 7 is installed to the rail transport vehicle 5, the second limiting groove 71 is clamped with the bottom plate on the rail transport vehicle 5, so as to limit the bearing frame 7 along the Y direction and prevent it from being displaced laterally during transportation, thereby improving the connection stability between the bearing frame 7 and the rail transport vehicle 5.

[0086] In an optional embodiment, as shown in Figure 8 and Figure 9 , the bearing frame 7 comprises a support beam 72, a clamping jaw 73 and an anti-skid claw 74. The support beam 72 extends along the Y direction and constitutes the main bearing structure of the bearing frame 7, which is used for supporting the rail plates and the like and transmitting the weight of the rail plates to the rail transport vehicle 5. The two ends of the support beam 72 are respectively connected with the clamping jaw 73, and the position of the clamping jaw 73 relative to the support beam 72 along the Z direction (i.e. the vertical direction) is adjustable. This adjustable structure can be realized by means of bolt connection, sliding groove adjustment, etc., so as to adapt to the structures of rail transport vehicles 5 with different thicknesses or heights and ensure that the bearing frame 7 can be stably installed on the rail transport vehicle 5.

[0087] The second limiting groove 71 is formed between the clamping jaw 73 and the bottom surface of the support beam 72, and is used for cooperating with the guide rail or other positioning structure on the rail transport vehicle 5 to limit the position of the bearing frame 7 relative to the rail transport vehicle 5 along the Y direction (i.e. the lateral direction), so as to prevent it from being displaced laterally or shaken during transportation, thereby improving the stability and safety during transportation.

[0088] Further, the anti-skid claws 74 are connected to the two side walls of the support beam 72 arranged opposite along the X direction (i.e. the conveying direction). The bottom end of the anti-skid claw 74 is provided with a sawtooth structure, which can be in contact with the upper surface of the track conveying vehicle 5 and embedded into the bottom plate of the track conveying vehicle 5, so as to prevent the carrier frame 7 from sliding along the X direction during the conveying process.

[0089] In the specific implementation, the support beam 72 and the anti-skid claw 74 can be assembled by welding or bolt connection of high-strength steel materials, so as to ensure the structural strength and the convenience of installation.

[0090] Through the above structural design, the carrier frame 7 can not only stably carry heavy objects such as track plates, but also realize the Y direction limiting through the cooperation of the second limiting groove 71 and the track conveying vehicle 5, and realize the X direction anti-skid through the sawtooth structure of the anti-skid claw 74, so as to realize the limiting and fixing in multiple directions, and significantly improve the safety and reliability during the conveying process of the track plate.

[0091] As shown in Figure 10 , the claw 73 includes a first plate body 731, a second plate body 732 and a third plate body 733 connected in sequence to form a "U" shaped structure, and the first plate body 731 is located in the support beam 72 and is provided with an adjusting bolt 75 between the first plate body 731 and the support beam 72. In the installation, the adjusting bolt 75 is screwed through the through hole on the support beam 72 and is screwed with the threaded hole on the first plate body, and the bottom end of the adjusting bolt 75 is locked by a nut. When it is necessary to adjust the position of the claw 73, the nut is loosened and the adjusting bolt is rotated. The above adjusting bolt 75 can be configured as one or multiple, when the adjusting bolt 75 is configured as one, the second plate body 732 and the support beam 72 are provided with an anti-deflection assembly, which can avoid the deflection of the claw 73 around the Y direction.

[0092] As shown in Figure 11 , the anti-deflection assembly includes a sliding groove 7321 provided on the second plate body 732 and a limiting piece 76 connected between the second plate body 732 and the support beam 72, the guiding part 761 in the limiting piece 76 is slidingly matched with the sliding groove 7321 along the Z direction, one end of the guiding part 761 is connected with a limiting disc 762, and the other end is connected with a threaded column 763, and the threaded column 763 is connected with a nut.

[0093] In use, the limiting disc is located on the inner side of the second plate body 732, the guiding part 761 passes through the sliding groove 7321 and the side wall of the support beam 72, and the threaded column 763 is located on the outer side of the side wall of the support beam 72 and is locked by the nut. When it is necessary to adjust the position of the claw 73, the nut is loosened.

[0094] In the optional embodiment, as shown in Figure 8As shown, the top end of the support beam 72 is provided with a third buffer pad 77. In use, the third buffer pad 77 is arranged between the support beam 72 and the bottommost track plate, and serves to provide a buffering effect when the track plate is carried, thereby reducing the mechanical stress suffered by the track plate during transportation due to vibration or impact, and preventing damage to the surface of the track plate or deformation of the structure.

[0095] The third buffer pad 77 is preferably made of an elastic material, such as rubber, polyurethane or other high-molecular materials having a damping performance. It can be fixed to the top surface of the support beam 72 by means of bonding, clamping or bolting, etc., to ensure that it does not displace or fall off during transportation.
