A pallet for transporting coiled steel

Abstract

The present invention relates to a pallet for transporting coiled steel, which relates to the field of railway transportation technology. The pallet comprises a base and multiple rows of triangular seats supported on the base. Adjacent triangular seats form a coiled steel bearing space for inserting and positioning the coiled steel. The triangular seats comprise two left and right sets of triangular seat square tubes and abutment ramps arranged at the inclined side ends of the two sets of triangular seat square tubes. The abutment ramps have an inclination of 38-39 degrees. The beneficial effects are that the transport vehicle is more stable during the process of transporting coiled steel and the pallet can adapt to coils of a larger diameter range. The overall width of the base is reduced to allow for stacking of multiple pallets, reducing the weight to alleviate transportation pressure, and the support surface is widened to ensure support strength when the I-beam or channel steel is changed to a hollow square tube. This increases the transportation efficiency and economy when transporting empty pallets.

Description

Technical Field

[0001] The present invention relates to the technical field of railway transportation, and in particular to a pallet for transporting coiled steel. Background Art

[0002] Steel coils, also known as coiled steel, are formed by hot or cold pressing steel into coils. This facilitates storage and transportation, and facilitates various processing steps (e.g., into steel plates, strips, etc.).

[0003] There are two common methods for transporting steel coils: sea and rail. Sea transport offers low transportation costs, large volumes, and wide coverage for large-volume steel coil shipments. It is also a relatively safe and reliable method for long-distance and seaborne transport. Rail transport is energy-efficient and environmentally friendly, connecting different regions of the country and facilitating the rapid transport of large quantities of steel coils. However, its disadvantage is its relatively long transport time, making it unsuitable for urgent shipments. Open wagons and container flatcars are two commonly used rail transport methods.

[0004] A railway open car is a freight car that has end walls, side walls, a floor but no roof, and is open upwards. The use of railway open cars to transport steel coils accounts for a large proportion of railway open car transportation. Due to the cylindrical shape of the steel coils, they are prone to displacement and rolling during transportation, which may further cause the railway open car to be overloaded and overweight, damage the railway open car components, and even cause major traffic accidents due to the falling of steel coils. Therefore, the existing technology has tried many methods to improve the stability of steel coils in railway open cars. Generally speaking, pallets are used to support the steel coils in the railway open car. The pallet includes a pallet base and multiple rows of triangular seats arranged on the pallet base. Space for the steel coils to be placed is formed between two adjacent rows of triangular seats, thereby positioning the steel coils. Conventional triangular seats are composed of two metal I-beams or channel steels on the left and right, and the support surface is 45°. The 45° support causes the center of gravity of the steel coils to move upward, making the railway open car more susceptible to the impact of the steel coils during transportation, resulting in less stable transportation.

[0005] At the same time, most current research and development focuses on the safety and stability of coiled steel transportation, often overlooking the inherent limitations of the pallets supporting the coils during transportation. For example, when transporting pallets (without the coils), multiple pallets are often stacked. Due to the high weight of a single pallet, the number of stacked pallets is limited, resulting in high transportation costs and a consequent impact on transportation efficiency and economic efficiency. Summary of the Invention

[0006] (1) Technical issues to be resolved

[0007] In view of the above-mentioned shortcomings and deficiencies of the prior art, the present invention provides a pallet for transporting coiled steel, which solves the problem of stacking of empty pallets during transportation; and further solves the technical problem of unstable transportation caused by coiled steel having too high a center of gravity during transportation of the pallet.

[0008] (2) Technical solution

[0009] In order to achieve the above objectives, the main technical solutions adopted by the present invention include:

[0010] An embodiment of the present invention provides a pallet for transporting coiled steel, comprising a base and a plurality of rows of triangular seats supported on the base, wherein the plurality of rows of triangular seats are arranged at intervals to form a coiled steel carrying space, and is characterized in that:

[0011] The triangular seat includes two groups of triangular seat square tubes connected at an angle to each other on the left and right sides, each group of triangular seat square tubes includes at least two triangular seat square tubes spaced apart in the front and back directions, and all the triangular seat square tubes in the group of triangular seat square tubes facing the coiled steel bearing space are parallel to each other and fixed with abutment inclined plates thereon.

[0012] This makes the transport vehicle more stable when transporting coiled steel and allows the pallet to adapt to a wider range of coiled steel diameters; the overall height of the base and the thickness of the triangular base are reduced to allow more pallets to be stacked, the weight is reduced to reduce transportation pressure, and the support surface is widened to ensure support strength when the I-beam or channel steel is changed to a hollow square tube; thereby increasing the transportation efficiency and economy when transporting empty pallets.

[0013] Optionally, the angle of the abutting inclined plate relative to the horizontal plane is 38-39 degrees;

[0014] The abutting inclined plate includes a metal plate layer and a deformation anti-slip rubber layer covering the metal plate layer.

[0015] By setting the abutment ramp angle to 38-39 degrees, the center of gravity of the steel coils placed within the coil-carrying space is lowered, thereby reducing the center of gravity of the transport vehicle. The deformable anti-skid rubber layer also increases friction between the coils and the steel, making transportation more stable. By thinning the triangular seat, the stacking height can be reduced; by lowering the angle, the stacking height can also be reduced.

[0016] Optionally, the inclined end surface of the abutment inclined plate facing the coil steel bearing space is an abutment inclined surface, and a stabilizing plate group is rotatably provided on the abutment inclined plate, and the stabilizing plate group rotates as the coil steel is inserted into the coil steel bearing space and is pressed against the side end of the coil steel, and the abutment inclined plate is slidably connected to the triangular seat square tube along the inclined direction of the abutment inclined surface, and the two abutment inclined plates located in the same coil steel bearing space move in opposite directions, and a stabilizing oil cylinder is provided between adjacent triangular seat square tubes to push the abutment inclined plates to move, and an inertia monitoring box for monitoring the start, emergency stop or stop of the transport vehicle is horizontally provided between two adjacent triangular seats, and the stabilizing oil cylinder pushes the abutment inclined surface to have a moving tendency to balance the moving tendency of the coil steel under the action of inertia.

[0017] An embodiment of the present invention proposes a pallet for transporting coiled steel. When the coiled steel is inserted into the coiled steel carrying space, the rotating stabilizing plate group will abut against the side end of the coiled steel, thereby reinforcing the coiled steel, and making the transportation process more stable. At the same time, when the transport vehicle starts, stops suddenly, or stops, the coiled steel will generate a large inertia, thereby exacerbating the instability. In this scheme, the abutting inclined plate is slidably connected to the triangular seat square tube, and then controlled by a stabilizing cylinder, so that the stabilizing cylinder can control the abutting inclined plate to move slightly. When the inertial monitoring box detects that the transport vehicle starts, stops suddenly, or stops, the stabilizing cylinder will push the adjacent abutting inclined plates to move in opposite directions, thereby dispersing the force acting on the abutting inclined plates when the coiled steel is subjected to inertia, thereby ensuring the stability of the coiled steel, so as to improve the stability of the railway open car in the process of transporting coiled steel.

[0018] Optionally, a mounting square hole is provided in the middle of the abutting inclined plate, and the stabilizing plate group includes a main plate rotatably connected to the mounting square hole, a sub-plate and a support column rotatably connected to the main plate, the rotating shafts of the main plate and the sub-plate are horizontal, the rotating shaft of the main plate is located on the upper side of the coil close to the abutting inclined surface, and the main plate is provided with a first hidden groove near the lower part of one end face of the coil bearing space, the rotating shaft of the sub-plate is located in the middle of the main plate and is rotatably inserted in the first hidden groove, the sub-plate forms an angle with the lower end of the main plate as it rotates, and the main plate is provided with a second hidden groove on the bottom wall of the first hidden groove, the support column is rotatably inserted in the first hidden groove, and the support column is perpendicular to the main plate as it rotates and is supported and connected to one end face of the sub-plate abutting the first hidden groove.

[0019] By opening a mounting square hole in the middle of the abutting inclined plate, the stabilizing plate group can be rotated and connected to the mounting square hole, so that when the coiled steel is not placed in the coiled steel carrying space, the triangular seat can be stacked, which saves more space. When the coiled steel needs to be transported, the sub-plate can be rotated to form an angle with the main plate, and then the support column is rotated to be perpendicular to the main plate, and the support column is fixed to the sub-plate. At this time, when the coiled steel is inserted into the coiled steel carrying space, the coiled steel will abut the sub-plate and push the sub-plate and the main plate to rotate together until the coiled steel abuts the abutting inclined plate. At this time, the upper part of the main plate will abut the side end of the coiled steel. At this time, the inclination angle of the main plate is greater than the inclination angle of the abutting inclined plate, thereby better limiting the coiled steel and ensuring the stability of the coiled steel during transportation.

[0020] Optionally, multiple groups of rollers are rotatably provided at the side end of the triangular seat square tube, and the rollers protrude from one side end of the triangular seat square tube close to the abutting inclined plate. Multiple groups of first limiting plates are vertically provided on an end surface of the abutting inclined plate close to the triangular seat square tube, and limiting grooves for the rollers to be inserted and rolled are formed between two adjacent first limiting plates. A second limiting plate is provided on one side of the first limiting plate, which abuts against one side end of the triangular seat square tube away from the roller, and a third limiting plate is vertically provided on one end of the second limiting plate away from the abutting inclined plate, which is parallel to the abutting inclined plate and abuts against one side end of the triangular seat square tube away from the abutting inclined plate.

[0021] By arranging a roller at the side end of the triangular seat square tube, the abutment inclined plate is abutted against the roller at one end face of the triangular seat square tube, thereby facilitating slight movement of the abutment inclined plate to balance the inertia of the rolled steel. At the same time, the moving stroke of the roller is limited by the first limiting plate to ensure that no greater instability is generated during the balancing process. The moving direction of the abutment inclined plate can be limited by the second limiting plate and the third limiting plate.

[0022] Optionally, two slide grooves are provided inside the inertial monitoring box along the moving direction of the transport vehicle, and the two slide grooves are connected at one end close to each other, and the connected end of the two slide grooves is lower than the other end. A monitoring ball is provided at the connection point of the two slide grooves inside the inertial monitoring box, and the monitoring ball rolls along the length direction of the two slide grooves due to inertia. A monitoring electric plate for the monitoring ball to touch is provided inside the inertial monitoring box at one end away from each other. The monitoring electric plate is touched by the monitoring ball to transmit a working signal to the stabilizing cylinder.

[0023] By setting two inclined chutes in the inertial monitoring box, the lowest ends of the two chutes are connected and a monitoring ball is placed. When the transport vehicle starts, stops suddenly or stops, the monitoring ball will roll along a chute and eventually touch the monitoring plate, thereby transmitting a working signal to the stabilizing cylinder, thereby completing the work of offsetting the inertia of the coiled steel.

[0024] Optionally, the base includes a rectangular bottom frame and a transverse beam and a longitudinal beam disposed inside the rectangular bottom frame, and a pair of blocking assemblies are provided on both side walls of the rectangular bottom frame along the width direction of the railway gondola, wherein the blocking assemblies are capable of abutting against the front side or the rear side of the reinforcement seat on the side wall of the railway gondola;

[0025] The blocking assembly includes a main blocking member and a tongue connected to the main blocking member so as to be rotatable up and down, and the main blocking member is fixedly connected to the rectangular bottom frame;

[0026] The latching tongue rotates up and down relative to the main latch between a first yielding position, a natural position, and a second yielding position;

[0027] The latch tongue extends laterally outward relative to the main latch when in the natural position;

[0028] When the pallet falls from top to bottom into the railway open car, the latch tongue is first pushed by the side wall beam of the railway open car and rotates upward from the natural position to the first yielding position. When the blocking assembly passes over the side wall beam, the latch tongue returns from the first yielding position to the natural position.

[0029] During the process of the pallet moving upward from the railway open car, the latch tongue is first pushed by the side wall beam and rotates downward from the natural position to the second yielding position. When the blocking assembly passes over the side wall beam, the latch tongue returns to the natural position from the second yielding position.

[0030] When a pallet is lowered into a railway open car from above, the latch is first pushed by the side wall beams of the railway open car, causing it to rotate upward from its natural position to a first clearance position, allowing the blocking assembly to pass over the side wall beams. Once the blocking assembly has passed over the side wall beams, the latch returns from the first clearance position to its natural position. When the pallet is removed from the railway open car from below, the latch is first pushed by the side wall beams, causing it to rotate downward from its natural position to a second clearance position, allowing the blocking assembly to pass over the side wall beams. Once the blocking assembly has passed over the side wall beams, the latch returns from the second clearance position to its natural position. This allows the latch, which extends outward in its natural position, to increase the effective width of the pallet, enhance the depth of engagement with the reinforcement seat, and improve stability. Furthermore, the latch rotates to avoid the side wall beams, thereby ensuring smooth loading of the pallet.

[0031] Optionally, the main latch has a groove, the latch tongue is rotatably located in the groove and extends from the groove when in the natural position;

[0032] The end of the tongue extending from the groove is formed by an upper inclined surface and a lower inclined surface, which is tapered toward the extension direction. The front side surface and the rear side surface of the end of the tongue extending from the groove are vertical planes, and the upper inclined surface and the lower inclined surface are connected by an arc end surface.

[0033] When the tray falls from top to bottom into the railway open car, the lower inclined surface of the latch tongue abuts against the side wall crossbeam, and is pushed so that the lower inclined surface is vertically oriented and flush with the end surface of the main latch, and the upper inclined surface is horizontally oriented;

[0034] When the tray is moved upward from the railway open car, the upper inclined surface of the latch tongue abuts against the side wall beam, and the upper inclined surface is vertically oriented and flush with the end surface of the main latch, and the lower inclined surface is horizontally oriented. The main latch has a groove, and the latch tongue is rotatably located in the groove and extends from the groove in the natural position.

[0035] The end of the tongue extending from the groove is formed by an upper inclined surface and a lower inclined surface, which is tapered toward the extension direction. The front side surface and the rear side surface of the end of the tongue extending from the groove are vertical planes, and the upper inclined surface and the lower inclined surface are connected by an arc end surface.

[0036] When the tray falls from top to bottom into the railway open car, the lower inclined surface of the latch tongue abuts against the side wall crossbeam, and is pushed so that the lower inclined surface is vertically oriented and flush with the end surface of the main latch, and the upper inclined surface is horizontally oriented;

[0037] During the process of the pallet moving upward from the railway open car, the upper inclined surface of the latch pushes against the side wall beam, and is pushed so that the upper inclined surface is vertically oriented and flush with the end surface of the main stop, and the lower inclined surface is horizontally oriented.

[0038] Optionally, the latch is rotatably connected to the main latch via a support shaft;

[0039] A first elastic piece and a second elastic piece connected to the main stop are respectively provided on the upper and lower sides of the latch tongue;

[0040] The first elastic piece and the second elastic piece press against the upper and lower surfaces of the latch in a natural state, so that the latch is in the natural position;

[0041] When the latch tongue rotates upward from the natural position to the first yielding position, the first elastic sheet bends upward along with the latch tongue;

[0042] During the process of the latch tongue rotating downward from the natural position to the second yielding position, the second elastic sheet bends downward along with the latch tongue.

[0043] Optionally, the rectangular bottom frame includes four square steels arranged in a rectangular shape, and a sling is installed at each of the four corners of the rectangular bottom frame and at the open end of the square steel, wherein the sling includes a hook portion, a ring portion, and a spacer portion;

[0044] The hook portion includes a first plate member, the first plate member extending from an open end of the square steel member and having a first hanging hole exposed on the square steel member, the first hanging hole penetrating the first plate member in a thickness direction thereof and penetrating a bottom wall of the first plate member;

[0045] The hanging ring portion includes a second plate member, the second plate member extends from an open end of the square steel member and is provided with a second hanging hole exposed on the square steel member, and the second hanging hole passes through the second plate member only in the thickness direction of the second plate member;

[0046] The first plate and the second plate are arranged in parallel and transversely, and the spacer is fixed between the two;

[0047] The hook portion is closer to the center line of the rectangular bottom frame relative to the ring portion.

[0048] By using a sling with both a hook and a ring, with the hook positioned closer to the centerline of the rectangular bottom frame than the ring, the ring has a closed shape and is more impact-resistant than the hook. Positioning the ring outside the hook protects the hook while also making the ring itself less susceptible to damage. Furthermore, the sling provides two different suspension structures, a hook and a ring, making it compatible with a wider range of suspension tools.

[0049] (3) Beneficial effects

[0050] The beneficial effects of the present invention are:

[0051] The present invention's pallet for transporting coiled steel features multiple square tubes on both sides of the triangular base, replacing the original I-beams or channels. While maintaining the same support strength, the thickness of a single square tube can be reduced; the weight of the square tubes relative to the I-beams or channels can be reduced; and the width of the multiple square tubes when arranged side by side can be significantly greater than the width of the original I-beams or channels, providing a wider support surface. Therefore, taking all factors into consideration, the present invention's design of multiple square tubes on a single side simultaneously reduces the height of the base unit to allow for stacking of multiple pallets, reduces weight to alleviate transportation pressure, and widens the support surface to ensure support strength when switching from I-beams or channels to hollow square tubes. This, in turn, increases the efficiency and economy of transporting empty pallets.

[0052] Furthermore, within the scope of the regulations and force calculations set out in the "Railway Cargo Loading Reinforcement Rules", the inclination angle of the abutting inclined plate is set to 38-39 degrees, so that when the steel coils are placed in the steel coil carrying space, the center of gravity of the steel coils is lower, thereby reducing the center of gravity when transporting the steel coils. At the same time, it can allow the pallet to adapt to steel coils with a larger diameter range.

[0053] At the same time, when the steel coil is inserted into the steel coil bearing space, the rotating stabilizing plate group will abut against the side end of the steel coil, thereby reinforcing the steel coil and making the transportation process more stable. At the same time, when the transport vehicle starts, stops suddenly or stops, the steel coil will generate a large inertia, thereby exacerbating the instability. In this solution, the abutting inclined plate is connected to the triangular seat square tube by sliding, and then controlled by the stabilizing cylinder, so that the stabilizing cylinder can control the abutting inclined plate to move slightly. When the inertial monitoring box detects that the transport vehicle starts, stops suddenly or stops, the stabilizing cylinder will push the adjacent abutting inclined plates to move in opposite directions, thereby dispersing the force acting on the abutting inclined plates when the steel coil is subjected to inertia, thereby ensuring the stability of the steel coil, so as to improve the stability of the steel coil during railway transportation.

[0079] In order to better explain the present invention and facilitate understanding, the present invention is described in detail below through specific implementation methods in conjunction with the accompanying drawings.

[0080] Example 1

[0081] Reference Figure 1 and Figure 4 A pallet for transporting coiled steel includes a base and two rows of triangular seats 6 supported on the base. The two rows of triangular seats 6 are arranged at intervals to form a coiled steel carrying space. This embodiment is a single-slot pallet.

[0082] The triangular base 6 comprises two sets of triangular base square tubes 62 connected at an angle to each other. Each set of triangular base square tubes 62 includes two triangular base square tubes 62 spaced apart in front and back. In the set of triangular base square tubes 62 facing the coiled steel holding space, all triangular base square tubes 62 are parallel to each other and fixed to abutment ramps 63. In this embodiment, due to the single-slot tray, only one side of each triangular base uses abutment ramps 63 to form a support surface for the coiled steel. When describing the triangular base 6, the front-to-back direction is defined as the axial direction of the coiled steel when placed in the coiled steel holding space, and the left-to-right direction is defined as the direction perpendicular to this axial direction.

[0083] As mentioned above, both sides of the triangular base are made of multiple square tubes instead of the original I-beams or channels. While maintaining the same support strength, the thickness of a single square tube can be reduced; the mass of the square tube relative to the I-beam or channel can be reduced; and the width of the multiple square tubes when arranged side by side can be significantly greater than the width of the original I-beam or channel, providing a wider support surface. Therefore, taking all factors into consideration, the solution of multiple square tubes on one side of the present invention can simultaneously reduce the height of the base unit to stack more pallets, reduce mass to alleviate transportation pressure, and widen the support surface to ensure support strength when the I-beam or channel is replaced by a hollow square tube. This in turn increases the transportation efficiency and economy when transporting empty pallets.

[0084] Furthermore, in this embodiment, the angle of the abutting inclined plate 63 relative to the horizontal plane is 38-39 degrees. This lowers the center of gravity of the steel coil when placed within the steel coil carrying space, thereby lowering the center of gravity when transporting the steel coil on the railway open car, improving stability and safety. Furthermore, the pallet can accommodate steel coils with a wider range of diameters.

[0085] Furthermore, the abutment inclined plate 63 comprises a metal plate layer and a deformable, non-slip adhesive layer 6411 covering the metal plate layer, providing sufficient support strength while reducing wear on the coiled steel. Specifically, the metal plate layer and the deformable, non-slip adhesive layer 6411 of the abutment inclined plate 63 are secured by bolts, and the metal plate layer is welded to the triangular seat square tube 62.

[0086] In this embodiment, the base includes a rectangular bottom frame A and horizontal beams and vertical beams welded inside the rectangular bottom frame A.

[0087] The rectangular bottom frame A includes four square steels 1 arranged in a rectangular shape. Adjacent square steels 1 are perpendicular to each other, and the adjacent square steels 1 can be directly connected or indirectly connected through other structures.

[0088] A sling 5 is installed at each of the four corners of the rectangular bottom frame A and at the open end 12 of the square steel 1, that is, a sling 5 is arranged at each of the four corners of the rectangular bottom frame A. Figure 1 From this perspective, three spreaders 5 can be seen, and another spreader 5 is blocked by the coiled steel.

[0089] In this embodiment (see Figures 1-4 ), four hangers 5 are mounted on a pair of opposing square steel bars 1 of the rectangular base frame A. Both ends of these square steel bars 1 have open ends 12, and a hanger 5 is mounted on each end of each square steel bar 1. As can be seen from the figure, the hangers 5 are installed on the two square steel bars 1 corresponding to the axial ends of the coiled steel. The directions in which the hangers 5 extend from the open ends 12 of the square steel bars 1 are two horizontal directions perpendicular to the axial direction of the coiled steel bearing space.

[0090] A portion of the sling 5 is inserted into the open end 12 of the square steel 1 , the portion located inside the square steel 1 is called the rear portion, and the portion exposed outside the square steel 1 is called the front portion.

[0091] The hanger 5 includes a hook portion 51 , a ring portion 52 , and a spacer portion 53 .

[0092] The hook portion 51 includes a first plate 511, which extends from the open end 12 of the square steel 1 and is provided with a first hanging hole 512 exposed from the square steel 1. In other words, the first hanging hole 512 is provided at the front of the first plate 511. The first hanging hole 512 penetrates the first plate 511 in the thickness direction and extends through the bottom wall of the first plate 511, thereby forming the hook shape of the protruding end of the hook portion 51. In short, the first hanging hole 512 of the hook portion 51, which is used to engage with a hanging tool, is open and is suitable for hanging tools such as wire rope loops.

[0093] Furthermore, in this embodiment, the first plate 511 is generally rectangular, comprising two parallel, relatively large side walls, a top wall, a bottom wall, a rear wall, a front wall, and a curved wall. The top and bottom walls are parallel and perpendicular to the side walls; the rear and front walls are parallel and perpendicular to the side walls; and the curved wall connects the front and bottom walls, outlining a hooked front end.

[0094] The end portion of the first plate 511 extending from the open end 12 of the square steel 1 is hook-shaped, and the bottom wall of the hook is retracted upward relative to the bottom wall of the first plate 511, forming a short hook for more convenient engagement with the suspension tool.

[0095] The eyelet portion 52 includes a second plate 521 that extends from the open end 12 of the steel bar 1 and is provided with a second hanging hole 522 exposed on the steel bar 1. The second hanging hole 522 extends through the second plate 521 only in the thickness direction of the second plate 521, thereby forming a ring shape at the extended end of the eyelet portion 52. In short, the second hanging hole 522 of the eyelet portion 52, which is used to engage with a hanging tool, is closed. The term "ring-shaped" here does not necessarily mean a circular ring; it simply means that the hanging hole for engaging with a hanging tool is closed, and is applicable when the hanging tool is a steel hook.

[0096] Furthermore, in this embodiment, the second plate 521 is rectangular and includes two parallel, relatively large side walls, a top wall, a bottom wall, a rear wall, and a front wall. The top wall and the bottom wall are parallel to and perpendicular to the side walls; the rear wall and the front wall are parallel to and perpendicular to the side walls.

[0097] The first plate 511 and the second plate 521 are parallel, meaning the side walls of the first plate 511 are parallel to the side walls of the second plate 521. Simultaneously, the top wall of the first plate 511 and the top wall of the second plate 521 are coplanar and parallel to the top wall of the square steel 1; the bottom wall of the first plate 511 and the bottom wall of the second plate 521 are coplanar and parallel to the bottom wall of the square steel 1, ensuring that the first plate 511 can be stably supported within the open end 12 of the square steel 1 after insertion. The first suspension hole 512 includes a semicircular hole and a rectangular hole smoothly connected to the semicircular hole, which passes through the bottom wall of the first plate 511. The second suspension hole 522 is a circular hole, with the axes of the semicircular and circular holes coinciding.

[0098] Moreover, the arrangement direction of the first plate 511 and the second plate 521 is horizontal, that is, the first plate 511 and the second plate 521 are arranged along the width or length direction of the rectangular bottom frame A, that is, along the width or length direction of the railway open car placed later; rather than stacked up and down.

[0099] The hook portion 51 is located closer to the centerline of the rectangular base frame A than the eye portion 52. The eye portion 52 has a closed shape and is more impact-resistant than the hook portion 51. Positioning the eye portion 52 outside the hook portion 51 protects the hook portion 51 while also making the eye portion 52 itself less susceptible to damage. This means that the pallet sling 5 is less susceptible to damage. Furthermore, the sling 5 provides two different suspension structures, the hook portion 51 and the eye portion 52, allowing it to accommodate a wider range of suspension tools, adapting to the varying conditions of slings at loading and unloading sites and eliminating the need for frequent sling replacement.

[0100] The spacer 53 is fixed between the two. The spacer 53 has two functions: on the one hand, it fixes the hook part 51 and the ring part 52 to form a whole that can be disassembled and assembled with the square steel 1; on the other hand, it allows the first suspension hole 512 and the second suspension hole 522 to be separated in the axial direction, thereby facilitating the connection of either one of the two with the suspension tool.

[0101] In this embodiment, two vertically spaced spacers 53 are provided. The first and second hanging holes 512 and 522 correspond to the area between the two spacers 53, providing space for the hanging tool. The spacers 53 are plate-shaped and perpendicular to the first and second plates 511 and 521. The end surface of the spacers 53 facing away from the square steel 1 (i.e., the front end surface of the spacers 53) is inclined relative to the first and second plates 511 and 521. The inclination direction is from the first plate 511 to the second plate 521, then away from the square steel 1, to make room for the first hanging hole 512 and, in turn, the hanging tool.

[0102] The top and bottom walls of the square steel 1 are each provided with mounting holes 11 as mounting locations. The spacer 53 is provided with a through-hole and is also connected to a mounting member fixed to the mounting location. The mounting member illustrated in this embodiment is a bolt 54 extending through the mounting hole 11 and the through-hole, and a nut 55 screwed onto the bolt 54. In this installation method, to ensure the stable fixation of the sling 5 in the square steel 1, the size of the portion of the sling 5 intended for insertion into the square steel 1 is as closely matched to the size of the open end 12 of the square steel 1 as possible. Rectangular gaskets 56 are provided on the outside of the top and bottom walls of the square steel 1, through which the bolts 54 pass.

[0103] Of course, the present invention is not limited thereto. In other embodiments, the sling 5 and the square steel 1 may be detachably connected by other means such as snap connection.

[0104] Furthermore, the material of the sling 5 is cast iron or cast steel, which is low in cost and has sufficient strength.

[0105] Example 2

[0106] See also Figure 5 The main differences between this embodiment and the first embodiment are the different triangular base structure, the different suspension structure of the rectangular bottom frame A, and the arrangement of the horizontal and vertical beams of the base. The specific description is as follows:

[0107] In this embodiment, four rows of triangular seats 6 are provided, and two adjacent rows of triangular seats 6 are arranged at intervals to form a steel coil carrying space. This embodiment is a three-slot pallet, which can hold three rows of steel coils.

[0108] Three triangular seat square tubes 62 are arranged side by side and spaced apart on the same side of the triangular seat 6, providing a wider support surface than the two triangular seat square tubes 62 in the first embodiment. The abutment ramp 63 covers all three triangular seat square tubes 62. In this embodiment, due to the three-slot tray, only one side of the two rows of triangular seats at the ends uses the abutment ramp 63 to form a support surface for the steel coils, while both sides of the two rows of triangular seats in the middle use the abutment ramp 63 to form a support surface for the steel coils.

[0109] The sling in the first embodiment is removed, and a conventional hook is provided on the side of the rectangular bottom frame A.

[0110] Example 3

[0111] See also Figure 6-Figure 14 The main differences between this embodiment and the first embodiment are the different triangular seat structure, the different suspension structure of the rectangular bottom frame A, and the addition of special corner pieces and blocking components. Specific descriptions are as follows:

[0112] In this embodiment, five rows of triangular seats 6 are provided, and two adjacent rows of triangular seats 6 are spaced apart to form a steel coil carrying space. This embodiment is a four-slot pallet, which can hold four rows of steel coils.

[0113] Among them, a horizontal reinforcement beam is added between the two triangular seat square tubes 62 on the same side of the triangular seat 6.

[0114] The sling in the first embodiment is removed, and a conventional hook is provided on the side of the rectangular bottom frame A.

[0115] This embodiment is unique in that four pairs of latching assemblies 2 are provided on the two side walls of the rectangular base frame A along the width of the gondola, namely, on the left and right side walls of the square steel 1. This is particularly suitable for use in gondola transport vehicles. When the pallet lands on the floor of the gondola, the latching assemblies 2 can abut against the front or rear sides of the reinforcement seats 31 on the side walls 3 of the gondola.

[0116] Specifically, three reinforcement seats 31 are spaced from front to back on one side wall 3 of the railway open car. Of the four blocking assemblies 2 on the same side of the rectangular base: the two middle blocking assemblies 2 are located on either side of the reinforcement seat 31 in the middle of the side wall 3; the first blocking assembly 2 located in the front is located behind the corresponding reinforcement seat 31 in the side wall 3; and the first blocking assembly 2 located in the rear is located in front of the corresponding reinforcement seat 31. Of course, the four blocking assemblies 2 on a single side are not limited to abutting all three reinforcement seats 31. As long as one blocking assembly 2 abuts the front side of one reinforcement seat 31 and the other blocking assembly 2 abuts the rear side of the same or another reinforcement seat 31, the longitudinal position of the entire pallet can be achieved.

[0117] The catch assembly 2 includes a main catch 21, a steel component fixedly connected to the square steel 1 in the rectangular base frame A. A groove is defined on the side of the main catch 21 facing away from the square steel 1. The catch assembly 2 also includes a steel tongue 22, pivotally connected to the main catch 21 via a support shaft 23 and positioned within the groove. In the illustrated position, the tongue 22 extends from the groove, extending laterally outward relative to the main catch 21.

[0118] A first spring clip 24 is provided on the upper side of the latch 22, and a second spring clip 25 is provided on the lower side. The ends of the first spring clip 24 and the second spring clip 25 close to the rectangular bottom frame A are connected to the main latch 21. In this embodiment, the first spring clip 24 and the second spring clip 25 are fixed by multiple bolts 54 passing through the main latch 21.

[0119] The first spring piece 24 and the second spring piece 25 press against the upper and lower surfaces of the tongue 22 (the rear surfaces of the upper inclined surface 221 and the lower inclined surface 222 described later) in the natural state, so that the tongue 22 is in the natural position, that is, the forces provided by the first spring piece 24 and the second spring piece 25 to the tongue 22 are symmetrical.

[0120] The first spring piece 24 includes a first long spring piece 241 and a first short spring piece 242. The first long spring piece 241 is longer than the first short spring piece 242 and abuts the latching tongue 22. The first short spring piece 242 overlaps the first long spring piece 241. The first long spring piece 241 covers a larger area of ​​the latching tongue 22 than the first short spring piece 242 in the direction of extension toward the latching tongue 22. The second spring piece 25 includes a second long spring piece 251 and a second short spring piece 252. The second long spring piece 251 is longer than the second short spring piece 252. The second long spring piece 251 abuts the latching tongue 22. The second short spring piece 252 overlaps the second long spring piece 251. The second long spring piece 251 covers a larger area of ​​the latching tongue 22 than the second short spring piece 252 in the direction of extension toward the latching tongue 22.

[0121] In this embodiment, a spring clip provides a restoring force, facilitating inspection and replacement. Of course, other embodiments of the present invention may also employ a torsion spring disposed on the support shaft 23. By using long and short spring clips, the force exerted by the long spring clip becomes very small as it returns to a straightened state. At this point, the short spring clip assists the long spring clip in returning to its original position. Furthermore, this prevents the long spring clip from locally fatigued and losing its elasticity. One or more spacers 26 may be provided between the long and short spring clips to adjust the spacing between them. For example, if the restoring force is insufficient, the number of spacers 26 can be reduced; if the force exerted by the tab 22 when bending upward or downward is excessive, the number of spacers 26 can be increased.

[0122] The latch 22 pivots vertically relative to the main latch 21 between an upwardly tilted first position, a horizontal neutral position, and a downwardly tilted second position. The end of the latch 22 extending from the groove of the main latch 21 is formed by an upper slope 221 and a lower slope 222, which taper toward the extension direction. The upper and lower slopes 221 and 222 are connected by a circular end face, and the inclinations of the upper and lower slopes 221 and 222 are the same. The front side 223 and rear side 224 of the end of the latch 22 extending from the groove of the main latch 21 are vertical planes.

[0123] When the latch tongue 22 is in the natural position, it extends outward laterally relative to the main latch 21 , that is, extends in a direction away from the rectangular bottom frame A.

[0124] As the pallet falls from top to bottom onto the railway open car, the latch 22 is first pushed by the railroad open car's side wall 3 beam and rotates upward from its natural position to the first yielding position. During this process, the lower inclined surface 222 of the latch 22 pushes against the side wall 3 beam, and the push causes the lower inclined surface 222 to be vertically oriented and flush with the end face of the main latch 21, while the upper inclined surface 221 is horizontally oriented. As a result, the latch 22 rotates into the groove of the main latch 21 and no longer extends laterally from the groove, allowing the latch assembly 2 to pass over the side wall 3 beam. Simultaneously, the first elastic leaf 24 bends upward with the latch 22 to accumulate force (at this time, both the first long elastic leaf 241 and the first short elastic leaf 242 bend upward), while the second elastic leaf 25 does not move. When the latch assembly 2 passes over the side wall 3 beam, the latch 22 returns from the first yielding position to its natural position under the restoring force of the first elastic leaf 24.

[0125] During the process of the tray moving upward out of the railway open car, the latch 22 is first pushed by the crossbeam of the side wall 3 and rotates downward from its natural position to the second yielding position. The upper inclined surface 221 of the latch 22 pushes against the crossbeam of the side wall 3, and the push is such that the upper inclined surface 221 is vertically oriented and flush with the end face of the main latch 21, while the lower inclined surface 222 is horizontally oriented. As a result, the latch 22 rotates into the groove of the main latch 21 and no longer extends laterally from the groove, allowing the latch assembly 2 to pass over the crossbeam of the side wall 3. At the same time, the second elastic leaf 25 bends downward with the latch 22 to accumulate force (at this time, the second long elastic leaf 251 and the second short elastic leaf 252 both bend downward), while the first elastic leaf 24 does not move. When the latch assembly 2 passes over the crossbeam of the side wall 3, the latch 22 returns from the second yielding position to its natural position under the restoring force of the second elastic leaf 25. In summary, this embodiment increases the effective width of the pallet by extending the latch 22 outward in a natural state, increases the depth of fit with the reinforcement seat 31, and improves stability. At the same time, the rotation of the latch 22 avoids the crossbeam of the side wall 3, thereby ensuring smooth loading of the pallet. Specifically, under normal loading conditions, the portion of the main latch 21 protruding from the pallet is used to be adjacent to and abut against the reinforcement seat 31, acting as the main latch; in the event of pallet jumping, the main latch 21 jumps out of the reinforcement seat 31, and because the latch 22 extends relative to the main latch 21, the front side 223 or the rear side 224 of the protruding portion of the latch 22 immediately abuts against the reinforcement seat 31, continuing to contribute to the longitudinal limitation of the pallet. It can be understood that the latch 22 serves as an auxiliary latch or a remedial latch.

[0126] In this embodiment, the internal width of the vehicle body is 2900 mm, and the distance between the two side wall 3 beams is 2800 mm. Based on this:

[0127] The width of the pallet at the outer ends of the main stops 21 on both sides is 2780-2800 mm, which ensures that the rigidly fixed main stops 21 can pass over the crossbeams of the side walls 3.

[0128] When the tongue 22 is in the natural position, the widest width of the tray (i.e., the lateral distance between the arc end faces of the tongues 22 in the two symmetrical blocking assemblies 2) is 2840-2890 mm, and the length of the tongue 22 extending from the groove is 20-50 mm. In this way, the matching depth with the reinforcement seat 31 is increased by 20-50 mm.

[0129] When the latch 22 is in the first and second positions, since the upper and lower slopes 221 and 222 of the latch 22 are flush with the end faces of the main catch 21 in this embodiment, the pallet's widest width is equal to the pallet's width at the outer ends of the main catches 21 on both sides, i.e., 2780-2800 mm. Of course, the present invention is not limited to this. When the latch 22 is in the first and second positions, it does not need to be fully rotated into the groove. However, the pallet's widest width must be less than or equal to 2800 mm to successfully pass through the side wall 3 beam.

[0130] The main latch 21 comprises two side supports 211, an upper plate 212, and a lower plate 213. The two side supports 211 are spaced apart to form a groove for accommodating the latch 22, which is rotatably supported on the two side supports 211. The upper plate 212 extends two arms that connect to the top ends of the two side supports 211, thereby forming a groove. The lower plate 213 is connected to the lower rear ends of the two side supports 211. The upper plate 212 covers the upper surface of the square steel 1 of the rectangular bottom frame A and is fixed to the square steel 1 of the rectangular bottom frame A, preferably by welding. The lower plate 213 is fixed to the side walls of the square steel 1 of the rectangular bottom frame A, preferably by welding.

[0131] In this embodiment, the side support member 211 is a U-shaped seat with an upward opening. This shape improves overall structural rigidity and reduces welding. The U-shaped seat is provided with a support hole that connects to the support shaft 23. The front side 223 and rear side 224 of the U-shaped seat are both vertical planes, thus forming the front side 223 and rear side 224 of the side support member 211 as vertical planes, facilitating contact and abutment with the corresponding reinforcement seat 31.

[0132] In this embodiment, a stop bar 13 is provided on the sidewall of the rectangular bottom frame A, connected to the catch assembly 2. The stop bar 13 is retracted relative to the main catch 21. When the pallet lands on the floor of the gondola, the stop bar 13 abuts against the inclined surface of the reinforcement seat 31 facing the centerline of the gondola. This stop bar 13 effectively limits the lateral movement of the pallet.

[0133] Reference Figure 11-13The pallet base A includes a rectangular bottom frame, which includes four square steels 1 arranged in a rectangular shape. Adjacent square steels 1 are perpendicular to each other, and the adjacent square steels 1 can be directly connected or indirectly connected through other structures. In this embodiment, the square steels 1 are connected at the four corners of the rectangular bottom frame by hollow corner pieces 14. The bottom wall of the corner piece 14 is provided with a long hole 141 that can be plugged into the mushroom head 4 of the container locking device on the railway container flat car, so that the pallet of this embodiment can also be used for railway transport container flat cars (the four-slot pallet is connected by four corner pieces, and the three-slot pallet and the single-slot pallet are only equipped with two corner pieces 14 at one end of the frame because the total length of the three-slot pallet and the single-slot pallet does not reach the length of the container. When the three-slot pallet and the single-slot pallet are used on the flat car, one side of the corner piece 14 is embedded in the mushroom head 4, and the other side is tied to the car body with steel wire).

[0134] Example 4

[0135] See also Figure 15-17 The present embodiment mainly describes the improvement on the structure of the triangular seat, which can replace or adaptably adjust the triangular seats in the first to third embodiments.

[0136] Specifically, a stabilizing plate assembly 64 is rotatably mounted on the abutting inclined plate 63. The stabilizing plate assembly 64 rotates as the steel coil is inserted into the steel coil carrying space 61 and abuts against the side ends of the steel coil. The abutting inclined plate 63 is tilted at a 38-39 degree angle, lowering the center of gravity of the steel coil when placed in the steel coil carrying space 61, thereby reducing the center of gravity of the transport vehicle when transporting the steel coil. Furthermore, when the steel coil is inserted into the steel coil carrying space 61, the rotating stabilizing plate assembly 64 abuts against the side ends of the steel coil, thereby reinforcing the steel coil and making the transportation process more stable.

[0137] The abutment inclined plates 63 are connected to the triangular seat square tubes 62 by sliding along the inclined direction of the abutment inclined surfaces 631. Stabilizing cylinders 65 are fixed obliquely between adjacent triangular seat square tubes 62 to push the abutment inclined plates 63 to move. The two abutment inclined plates 63 located in the same coil bearing space 61 move in opposite directions, so that the stabilizing cylinders 65 push the abutment inclined surfaces 631 to move in a manner that balances the movement tendency of the coil under the action of inertia.

[0138] The side end of the triangular seat square tube 62 is rotatably connected to multiple groups of rollers 621 through a rotating shaft. The rollers 621 protrude from one side end of the triangular seat square tube 62 close to the abutting inclined plate 63. Multiple groups of first limiting plates 632 are vertically welded to an end surface of the abutting inclined plate 63 close to the triangular seat square tube 62. A limiting groove 633 for the rollers 621 to be inserted and rolled is formed between two adjacent first limiting plates 632. A second limiting plate 634 is welded to one side of the first limiting plate 632 of the abutting inclined plate 63, which abuts against the side end of the triangular seat square tube 62 away from the roller 621. A third limiting plate 635 is vertically welded to the end of the second limiting plate 634 away from the abutting inclined plate 63, which is parallel to the abutting inclined plate 63 and abuts against the side end of the triangular seat square tube 62 away from the abutting inclined plate 63. By arranging a roller 621 at the side end of the triangular seat square tube 62, the abutting inclined plate 63 is abutted against the roller 621 at one end surface close to the triangular seat square tube 62, thereby facilitating slight movement of the abutting inclined plate 63 to balance the inertia of the coiled steel. At the same time, the moving stroke of the roller 621 is limited by the first limiting plate 632 to ensure that no greater instability is generated during the balancing process. The moving direction of the abutting inclined plate 63 can be limited by the second limiting plate 634 and the third limiting plate 635.

[0139] An inertial monitoring box 66 for monitoring the start, emergency stop or stop of the transport vehicle is fixed horizontally on the square steel 1 of the rectangular bottom frame A between two adjacent triangular seats 6.

[0140] Two chute slots 661 are located inside the inertia monitoring box 66, running along the direction of the transport vehicle's movement. The two chute slots 661 are connected at their respective ends, with the connecting end lower than the other end. A monitoring ball 662 is placed at the junction of the two chute slots 661, rolling along the length of the two chute slots 661 due to inertia. A monitoring plate 663, contacted by the monitoring ball 662, is located at the distal end of the two chute slots 661. This plate 663 is contacted by the monitoring ball 662, transmitting an operating signal to the stabilizing cylinder 65. When the transport vehicle starts, stops suddenly, or comes to a complete stop, the monitoring ball 662 rolls along one of the chute slots 661 and eventually contacts the monitoring plate 663, transmitting an operating signal to the stabilizing cylinder 65, thereby offsetting the coil's inertia.

[0141] A mounting square hole 636 is provided in the middle of the abutting inclined plate 63. The stabilizing plate assembly 64 includes a main plate 641 rotatably connected to the mounting square hole 636 via a rotating shaft, a sub-plate 642 rotatably connected to the main plate 641 via a rotating shaft, and a support column 643. The rotating shafts of the main plate 641 and the sub-plate 642 are horizontal. The rotating shaft of the main plate 641 is located on the upper side of the portion of the coil close to the abutting inclined surface 631. The main plate 641 is provided with a second hole 636 at the lower part of one end surface of the coil bearing space 61. A hidden groove 644, the rotating shaft of the sub-plate 642 is located in the middle of the main plate 641 and is rotatably inserted into the first hidden groove 644. The sub-plate 642 forms an angle with the lower end of the main plate 641 as it rotates. The main plate 641 is provided with a second hidden groove 645 on the bottom wall of the first hidden groove 644. The support column 643 is rotatably inserted into the first hidden groove 644. The support column 643 is perpendicular to the main plate 641 as it rotates and supports and connects to one end surface of the sub-plate 642 that abuts against the first hidden groove 644. The stabilizing plate group 64 is rotatably connected to the mounting square hole 636, so that when the steel coil is not placed in the steel coil carrying space 61, the triangular seat 6 can be stacked, which saves more space. When the steel coil needs to be transported, the sub-plate 642 can be rotated to form an angle with the main plate 641, and then the support column 643 is rotated to be perpendicular to the main plate 641, and the support column 643 is fixed to the sub-plate 642. At this time, when the steel coil is inserted into the steel coil carrying space 61, the steel coil will abut against the sub-plate 642 and push the sub-plate 642 and the main plate 641 to rotate together until the steel coil abuts against the abutting inclined plate 63. At this time, the upper part of the main plate 641 will abut against the side end of the steel coil. At this time, the inclination angle of the main plate 641 is greater than the inclination angle of the abutting inclined plate 63, thereby better limiting the steel coil and ensuring the stability of the steel coil during transportation.

[0142] The abutting inclined plate 63 has multiple sets of rotation holes 637 spaced evenly along the length of the mounting hole 636 on either side. The main plate 641 can be removably and rotatably inserted into any set of corresponding horizontal rotation holes 637. This allows for adjustment of the position of the stabilizing plate assembly 64, allowing it to more conveniently reinforce coils of any size.

[0143] A deformable, non-slip adhesive layer 6411 is bonded to the upper side of one end of the main plate 641, near the steel coil loading space 61. Once installed, the steel coil abuts against this layer. This increases friction between the coil and the main plate 6411, making it more stable. Furthermore, when the steel coil sways slightly during transport, this layer deforms slightly, providing a buffer and preventing damage to the stabilizing plate assembly 64 from collisions, thereby extending the service life of the stabilizing plate assembly 64.
