Description

Technical Field

[0001] The present invention relates to the technical field of plate transport equipment, in particular to a plate flat car transport frame and a flat and collection dual-purpose transport vehicle. Background Art

[0002] At present, the railway transportation of medium and thick plate cargo is to place the plate cargo evenly on the floor of the flatbed truck, with the projection of the total center of gravity of the cargo falling on the intersection of the longitudinal and transverse center lines. Multiple strips of grass pads are evenly laid on the bottom and between the layers of the plate cargo, and the reverse pulling and binding is carried out by using φ10mm (millimeter) ratchet fasteners combined with iron wires, etc., and the bolting points are the support grooves and T-irons on the side of the car body. The two outer ends of the steel plate are cross-pulled with φ6.5mm (millimeter) wire rods and tied to the T-irons or support grooves on the side of the car body.

[0003] Fixing of steel plates requires horizontal bundling and longitudinal pulling, and the addition of anti-wear pads at the corners of the vehicle. The operation is cumbersome and the working efficiency is low.

[0004] However, the existing methods for fixing medium and thick plates often have the following defects: auxiliary materials such as wire rope fasteners, wire rods, anti-wear pads, and strip grass pads are used for steel plate loading and reinforcement, and the cost of reinforcement materials is relatively high.

[0005] Most of the auxiliary materials used in steel plate reinforcement operations are disposable consumables and cannot be reused, which is not conducive to environmental protection.

[0006] The steel wire rope fasteners and the bolt connection points of the wire rods are the support grooves or T-irons on both sides of the car body. Since huge inertial force will be generated during vehicle marshaling or emergency braking, but the rigidity and strength of the support grooves and T-irons are very limited, this inertial force often damages the support grooves or T-irons. Summary of the invention

[0007] 1. Technical issues to be resolved

[0027] (III) Beneficial effects

[0028] Compared with the prior art, the plate flat car transport frame provided by the present invention has the following advantages:

[0029] By placing the plate to be transported on the chassis assembly, and then using a pair of end flip stop structures arranged in an interval manner along the length direction of the chassis assembly to limit the width direction of the plate to be transported to the left and right, the plate to be transported is effectively prevented from shaking on the chassis assembly, thereby achieving the fixation of the plate to be transported.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0046] like Figures 1 to 8 As shown, the figure schematically shows that the plate flat car transport frame includes a base frame assembly 1 and a pair of end flip stop structures 2.

[0047] In the embodiment of the present application, the chassis assembly 1 is used to receive and transport the plate 200 .

[0048] A pair of end flip stop structures 2 are arranged at intervals along the length direction of the chassis assembly 1 and are used to prevent the plate 200 to be transported from moving left and right along the width direction of the chassis assembly 1. Specifically, the plate 200 to be transported is placed on the chassis assembly 1, and then the pair of end flip stop structures 2 arranged at intervals along the length direction of the chassis assembly 1 are used to limit the width direction of the plate 200 to be transported left and right, so as to effectively prevent the plate 200 to be transported from shaking on the chassis assembly 1, thereby achieving the fixation of the plate 200 to be transported. It can be seen that the plate flat car transport frame of the present invention does not need to use auxiliary materials such as wire rope fasteners, wire rods, anti-wear pads, and strip grass pads when fixing the plate 200 to be transported, that is, the cost of reinforcement is effectively reduced.

[0049] In addition, in the prior art, when fixing the transport plate 200, the auxiliary materials used are mostly disposable consumables and cannot be reused, which is not environmentally friendly. However, the plate flat car transport frame of the present invention can be reused.

[0050] In addition, compared with the prior art, the bolting points of the steel wire rope fastener and the wire rod for binding the plates 200 to be transported are the support grooves or T-irons on both sides of the vehicle body. Since a huge inertial force will be generated during vehicle marshaling or emergency braking, but the rigidity and strength of the support grooves and T-irons themselves are very limited, this inertial force will often damage the support grooves or T-irons. However, the plate flat car transport frame of the present invention can complete the fixation of the plate 200 to be transported only by the end flip stop structure 2, and will not cause damage to the support grooves or T-irons on both sides of the vehicle body, effectively extending the service life of the vehicle body.

[0051] The so-called "length direction" refers to Figure 1 The horizontal line direction between the two end flip stop structures 2 is shown.

[0052] The so-called "width direction" refers to Figure 1 The horizontal line direction between the long sides of the chassis assembly 1 is shown.

[0053] It should be noted that the so-called “plate 200 to be transported” can be a plate-like structure made of any material, such as steel, aluminum, plastic, etc.

[0054] The plate 200 to be transported may have multiple layers in the longitudinal direction, and the specific number of layers is not limited here.

[0055] When in use, the plate flatbed transport frame of the present application can be two groups, used to fix a stack of plates 200 to be transported, and the plate flatbed transport frames are respectively arranged at the ends of the plates 200 to be transported, wherein the distance between the two end flip stop structures 2 is exactly equal to the width of the plates 200 to be transported. The end flip stop structures 2 arranged in the plate flatbed transport frame at each end of the plates 200 to be transported can clamp and fix the corresponding ends of the plates 200 to be transported.

[0056] Alternatively, the plate flatbed transport frame of the present application may be four groups, which are used to fix two piles of plates 200 to be transported, and the two piles of plates 200 to be transported are separated by the flip column partition 8 described below.

[0057] like Figure 1 As shown, in a preferred embodiment of the present application, the chassis assembly 1 includes a first short side beam 11 and a second short side beam 12 which are arranged opposite to each other.

[0058] The chassis assembly 1 further includes a first long side beam 13 and a second long side beam 14 which are arranged opposite to each other. The first short side beam 11, the first long side beam 13, the second short side beam 12 and the second long side beam 14 are sequentially connected end to end to form a closed frame.

[0059] A slideway (not shown) with an opening toward the geometric center line of the length direction of the frame is constructed on the inner side surface of the first long side beam 13 and the second long side beam 14. Specifically, the slideway is used to fix the slider 22 described below.

[0060] like Figure 5 As shown, in a preferred embodiment of the present application, a pair of end flip stop structures 2 each include a connecting shaft 21, and a slider 22 disposed at the end of the connecting shaft 21, and the slider 22 is respectively adapted to the slideway on the corresponding side. Specifically, the center point of the slider 22 is located on the extension line of the central axis of the connecting shaft 21. That is, the central axis of the connecting shaft 21 is perpendicular to the horizontal plane where the slider 22 is located.

[0061] By making the slider 22 slide along the length direction of the slideway, the end flip stop structure 2 can be driven to slide together, thereby achieving the purpose of being able to adapt to the plates 200 to be transported of different lengths.

[0062] like Figure 1 and Figure 7As shown, in a preferred embodiment of the present application, a pair of the end flip stop structures 2 also include a transverse flip stop frame 23 disposed on the connecting shaft 21, wherein the transverse flip stop frame 23 can prevent the transported plate 200 from moving left and right between the first long side beam 13 and the second long side beam 14. It should be noted that the so-called "left and right direction" in this embodiment refers to the horizontal connection direction between the first long side beam 13 and the second long side beam 14.

[0063] like Figure 1 and Figure 5 As shown, in a preferred embodiment of the present application, the plate flat car transport frame further includes a longitudinal limiting structure 3, which is arranged on each of the end flip stop structures 2 and is used to press the plate 200 to be transported. Specifically, the arrangement of the longitudinal limiting structure 3 can effectively limit the movement of the plate 200 to be transported in the upper and lower positions. The longitudinal limiting structure 3 can further fix the plate 200 to be transported on the basis of only the end flip stop structure 2, so that the plate 200 to be transported can be fixed more firmly.

[0064] like Figure 5 As shown, in another preferred embodiment of the present application, the longitudinal limiting structure 3 includes a screw rod 31, a first end of the screw rod 31 is arranged on the top cross beam of the lateral flip stop frame 23, and a second end of the screw rod 31 extends downward in a direction away from the top cross beam.

[0065] The first end of the screw rod 31 can be fixed to the top crossbeam of the transverse flip stop frame 23 by welding or bolting.

[0066] The longitudinal limiting structure 3 further includes a lower pressing plate 32, which is sleeved on the screw rod 31, and a threaded hole (not shown in the figure) is configured on the lower pressing plate 32, and the threaded hole is adapted to the screw rod 31. Specifically, by rotating the lower pressing plate 32, the lower pressing plate 32 can move up and down in the axial direction of the screw rod 31, and by rotating the lower pressing plate 32, the thickness of the plate 200 to be transported can be adapted to different thicknesses, so as to press the plate 200 to be transported of corresponding thickness.

[0067] It should be noted that the shape of the lower pressing plate 32 can be circular, elliptical, rectangular, etc.

[0068] like Figure 1 and Figure 5As shown, in a preferred embodiment of the present application, through holes are constructed at the bottom of the side panels on both sides of the lateral flipping retainer 23 for the connecting shaft 21 to pass through, wherein the lateral flipping retainer 23 can rotate from a vertical position to a horizontal position toward the center of the frame around the connecting shaft 21. In other words, the lateral flipping retainer 23 can be flexibly rotated between 0° and 90°. When the lateral flipping retainer 23 needs to be stopped, the lateral flipping retainer 23 is in a vertical position. When the lateral flipping retainer 23 does not need to be stopped, the lateral flipping retainer 23 can be swung 90° clockwise from the current vertical position to a horizontal position. It can be seen that the lateral flipping retainer 23 has good flexibility in use.

[0069] like Figure 1 As shown, in a preferred embodiment of the present application, a plurality of first positioning holes 131 are configured at intervals along the length direction of the first long side beam 13 at the end of the first long side beam 13 .

[0070] A plurality of second positioning holes 141 are spaced apart at the end of the second long side beam 14 along the length direction of the second long side beam 14 , wherein each of the first positioning holes 131 is disposed opposite to the corresponding second positioning hole 141 .

[0071] The plate flat car transport frame also includes a stopper frame positioning shaft 4, which is respectively arranged on the side end surface of the transverse flip stopper frame 23 on the corresponding side, wherein one end of the stopper frame positioning shaft 4 can be inserted into the corresponding first positioning hole 131 or the second positioning hole 141, and the other end abuts against the side end surface of the transverse flip stopper frame 23. Specifically, when the transverse flip stopper frame 23 is in a stopping state, by inserting one end of the stopper frame positioning shaft 4 into the corresponding first positioning hole 131 or the second positioning hole 141, and the other end abuts against the side end surface of the transverse flip stopper frame 23, the transverse flip stopper frame 23 is effectively prevented from moving along the length direction of the first long side beam 13 and the second long side beam 14.

[0072] like Figure 5 As shown, in a preferred embodiment of the present application, a first through hole (not shown in the figure) is constructed on the connecting shaft 21, a connecting beam 231 is provided at the bottom of the lateral flip blocking frame 23, and a second through hole (not shown in the figure) is constructed on the connecting beam 231, and the first through hole and the second through hole are jointly constructed into a combined through hole.

[0073] The plate flat car transport frame also includes a positioning pin 5, which is matched with the combined through hole. Specifically, when the lateral flip block 23 needs to be stopped, when the lateral flip block 23 is adjusted to a vertical position, in order to prevent the lateral flip block 23 from rotating during positioning, the positioning pin 5 can be inserted into the combined through hole, so that the lateral flip block 23 can be effectively prevented from rotating, thereby locking the lateral flip block 23.

[0074] like Figure 1 and Figure 6 As shown, in a preferred embodiment of the present application, the plate flat car transport frame further includes a pair of flip columns 6, which are arranged on the first long side beam 13 in an interval manner, wherein each flip column 6 can be rotated from a vertical position to a horizontal position. Specifically, when it is necessary to stop the plate 200 to be transported to prevent the plate 200 to be transported from falling from the bottom frame assembly 1, the flip column 6 should be in a vertical position. On the contrary, when the flip column 6 does not need to stop the plate 200 to be transported, the flip column 6 can be rotated to a horizontal position for hiding.

[0075] like Figure 6 As shown, in a preferred embodiment of the present application, the flip column 6 is hinged to the first long side beam 13 through a rotating shaft 61, wherein a circular hole 62 and a rectangular hole 63 connected to the lower end of the circular hole 62 are sequentially and spaced from top to bottom in the longitudinal direction at the bottom of the flip column 6.

[0076] The end of the rotating shaft 61 is configured as a flat portion. When the rotating shaft 61 is lifted, the flat portion can rotate circumferentially in the circular hole 62. When the rotating shaft 61 is pressed down, the flat portion can be embedded in the rectangular hole 63 and fit with the rectangular hole 63. Specifically, when the flip column 6 needs to be rotated, the flip column 6 can be lifted so that the flat portion of the rotating shaft 61 is located in the circular hole 62, so that the rotating shaft 61 can rotate freely.

[0077] On the contrary, when the flip pillar 6 does not need to be stopped, the flip pillar 6 can be pressed down so that the flat portion of the rotating shaft 61 is embedded in the rectangular hole 63 to prevent the rotating shaft 61 from rotating.

[0078] like Figure 1 and Figure 4 As shown, in a preferred embodiment of the present application, a pair of supporting beams 7 are spaced apart along the length direction of the first long side beam 13 and the second long side beam 14, and both ends of the pair of supporting beams 7 are respectively connected to the first long side beam 13 and the second long side beam 14 on the corresponding sides.

[0079] The side surfaces of the pair of supporting beams 7 facing each other are both provided with flip column partitions 8. Specifically, when the flip column partitions 8 are in a vertical position, they can separate adjacent stacks of the transported plates 200 to prevent the adjacent stacks of the transported plates 200 from colliding with each other.

[0080] like Figure 1 As shown, in another preferred embodiment of the present application, a flexible gasket 9 is constructed on the upper end surface of the first long side beam 13 and the second long side beam 14. Specifically, the flexible gasket 9 can be fixed to the upper end surface of the first long side beam 13 and the second long side beam 14 by bolt connection, bonding or snap connection.

[0081] Since the plates 200 to be transported are placed on the upper end surfaces of the first long side beam 13 and the second long side beam 14, the provision of the flexible gasket 9 can play a buffering and soft contact role, protecting the plates 200 to be transported and preventing scratches on their surfaces.

[0082] In one embodiment of the present application, the flexible gasket 9 may be a silicone gasket, a rubber gasket or other flexible gaskets.

[0083] like Figure 4 As shown, in a preferred embodiment of the present application, the plate flat car transport frame further includes a pair of connecting members 10, and the pair of connecting members 10 are both arranged on the lower end surfaces of the first long side beam 13 and the second long side beam 14, and each of the connecting members 10 is respectively arranged vertically with the first long side beam 13 and the second long side beam 14. Specifically, the connecting members 10 can be fixed to the lower end surfaces of the first long side beam 13 and the second long side beam 14 by welding or bolting.

[0084] like Figure 4 As shown, in another preferred embodiment of the present application, each of the connecting members 10 includes a connecting rib 101, which is arranged on the lower end surfaces of the first long side beam 13 and the second long side beam 14, and each of the connecting ribs 101 is vertically arranged with the first long side beam 13 and the second long side beam 14 respectively.

[0085] A plurality of connection holes 102 with openings facing downward are arranged at intervals on the lower end surface of the connection rib 101 along the length direction of the connection rib 101. It should be noted that the connection holes 102 are provided to match the protrusions on the body bottom plate of the flatbed vehicle described below.

[0086] A protrusion may be accommodated in each connection hole 102, and a plurality of connection holes 102 are respectively matched with corresponding protrusions, so as to achieve the purpose of enhancing the installation strength of the plate flat car transport frame in the flat car.

[0087] According to a second aspect of the present invention, there is also provided a flatbed transport vehicle, comprising a vehicle body floor (not shown in the figure) and the above-mentioned plate flatbed transport frame, the plate flatbed transport frame being arranged on the vehicle body floor.

[0088] In a preferred embodiment of the present application, at least two groups of protrusion structures are provided at intervals on the vehicle body bottom plate along the width direction of the vehicle body bottom plate, and each group of the protrusion structures includes a plurality of protrusions provided at intervals along the longitudinal direction of the vehicle body bottom plate (i.e., the length direction of the vehicle body), and each of the protrusions is respectively matched with the connection holes 102 on the corresponding connection ribs 101 in the plate flat car transport frame. It should be noted that as long as the protrusions can be matched with the connection holes 102, the installation of the plate flat car transport frame on the vehicle body bottom plate of the flatbed and dual-purpose transport vehicle can be achieved.

[0089] Each protrusion may correspond to one connection hole 102 , or some protrusions may correspond to some connection holes 102 in a one-to-one manner.

[0090] In summary, by placing the plate 200 to be transported on the chassis assembly 1, and then using a pair of end flip stop structures 2 arranged at intervals along the length direction of the chassis assembly 1 to limit the width direction of the plate 200 to be transported to the left and right, the plate 200 to be transported can be effectively prevented from shaking on the chassis assembly 1, thereby achieving the fixation of the plate 200 to be transported. It can be seen that the plate flat car transport frame of the present invention does not need to use auxiliary materials such as wire rope fasteners, wire rods, anti-wear pads, and strip straw pads when fixing the plate 200 to be transported, that is, the cost of reinforcement is effectively reduced.

[0091] In addition, in the prior art, when fixing the transport plate 200, the auxiliary materials used are mostly disposable consumables and cannot be reused, which is not environmentally friendly. However, the plate flat car transport frame of the present invention can be reused.

[0092] In addition, compared with the prior art, the bolting points of the steel wire rope fastener and the wire rod for binding the plates 200 to be transported are the support grooves or T-irons on both sides of the vehicle body. Since a huge inertial force will be generated during vehicle marshaling or emergency braking, but the rigidity and strength of the support grooves and T-irons themselves are very limited, this inertial force will often damage the support grooves or T-irons. However, the plate flat car transport frame of the present invention can complete the fixation of the plate 200 to be transported only by the end flip stop structure 2, and will not cause damage to the support grooves or T-irons on both sides of the vehicle body, effectively extending the service life of the vehicle body.

[0093] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
