Description

Technical Field

[0001] The utility model relates to the technical field of shelves, in particular to a through-type shelf ground rail connection structure. Background Art

[0002] Drive-through storage racks, also known as corridor racks, are an efficient rack storage system, especially suitable for storing goods in large batches and with a small variety.

[0003] Warehouse racks have multiple transport lanes to facilitate forklifts stacking, moving, and storing goods. When operators drive forklifts through the transport lanes, their movement trajectory inevitably deviates. If the deviation is large, it may touch the warehouse racks, potentially causing damage to the racks, goods, or forklifts. To reduce large deviations when operators drive forklifts, floor rails are installed in the middle of the warehouse racks' transport lanes. The forklifts move along the floor rails to prevent them from colliding with the shelves on either side. However, existing floor rails are only fixed to the ground with bolts. Over long-term use, when the forklift starts, accelerates, decelerates, or brakes, it will generate horizontal thrust, vibration, or impact on the floor rails. The fixing bolts or welding points of the floor rails may loosen due to the continuous vibration and impact, thereby affecting the normal movement of the forklift and potentially preventing the goods from being stably placed in the corresponding position of the warehouse racks. Utility Model Content

[0004] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a through-type shelf floor rail connection structure.

[0005] The technical solution of this utility model is as follows:

[0006] A through-type rack floor rail connection structure, the through-type rack has multiple parallel transport channels, each of which is equipped with a floor rail, and the bottom of the through-type rack is provided with a bottom transverse support channel parallel to the floor rail. Both sides of the floor rail in the width direction are connected to adjacent bottom transverse support channel steels through symmetrically arranged connection units. The connection unit includes an elongated plate and a connection assembly. One end of the elongated plate is detachably connected to the lower part of the floor rail, and the other end is detachably connected to the bottom of the through-type rack through the connection assembly, and the elongated plate is arranged perpendicular to the floor rail.

[0007] A connecting plate is provided at one end of the long plate close to the bottom transverse supporting channel steel;

[0008] The connecting assembly includes a connecting piece and a plug-in piece. One end of the plug-in piece passes through the lower part of the connecting plate to the inside of the bottom horizontal support channel steel. The lower end of the connecting piece passes through the upper part of the connecting plate and the bottom horizontal support channel steel in the vertical direction in sequence, and is detachably connected to one end of the plug-in piece.

[0009] The specific structure of the above-mentioned connecting plate is that, since a bottom horizontal support channel steel is provided at the bottom of the through-type shelf, in order to facilitate the connection and fixation of the bottom horizontal support channel steel, the connecting plate is set as an L-shaped plate, including a long plate and a short plate connected vertically. The long plate is set vertically, the bottom end of the long plate is fixedly connected to the long plate, and the short plate is fixedly connected to the upper end of the long plate. The short plate is located above the bottom horizontal support channel steel, and one end of the connector is plugged into the long plate.

[0010] Since the connecting plate is directly connected through the connecting piece, the lower part of the connecting plate cannot be fixed well, resulting in low stability of the end of the long plate and prone to vibration. For this reason, the axis of the connector is perpendicular to the axis of the connector, and the plug-in connector is located on the long plate close to one end of the long plate. The position of the plug-in connector is set lower, and the plug-in connector and the connecting plate are fixed through the connecting piece, which can better fix the upper part of the connecting plate and the end of the long plate.

[0011] Regarding the height position of the connector, the vertical distance between the axis of the connector and the upper surface of the long plate is 3-10 mm. This range makes it easy to install the connector, and the height of the connector will not be too high.

[0012] The thickness of the long plate is less than 3 mm, and the lower surface of the long plate is in close contact with the ground. Within this range, the thickness will not affect the stability of the forklift's movement.

[0013] The specific structure of the above-mentioned plug-in connector is that one end of the plug-in connector located inside the bottom horizontal supporting channel steel is provided with a plug-in hole adapted to the connecting piece.

[0014] Regarding the specific structure of the plug-in hole, the inner wall of the plug-in hole includes an internal thread section and a circular hole section distributed up and down. The inner diameter of the circular hole section is smaller than the inner diameter of the internal thread section. The lower part of the connector is provided with an external thread that is adapted to the internal thread section. The connector is threadedly connected to the internal thread section, and the connector is threadedly connected to the short plate. Continuing to tighten the connector downward can enable the connector to push the connector downward to prevent the connector from shaking.

[0015] The specific structure of the above-mentioned connecting piece is that the connecting piece includes a screw, a limit platform is sleeved on the upper part of the screw, a through threaded hole for passing the screw is opened on the short plate, and the outer diameter of the limit platform is larger than the inner diameter of the through threaded hole.

[0016] In order to facilitate accurate insertion of the screw into the plug hole, the lower end of the screw is provided with a conical tip.

[0017] The beneficial effects of the present invention are:

[0018] The same floor rail is connected to the bottom of the drive-through rack through two symmetrically arranged connecting units. The long plates on both sides of the same floor rail can be connected to the bottom transverse support channel steels on both sides of the floor rail through connecting plates and connecting components, which increases the connection strength of the floor rail in the transverse direction, reduces the loosening phenomenon caused by long-term starting, acceleration, deceleration or braking of the forklift on the floor rail, and improves the smoothness of forklift movement and the transportation stability of goods;

[0019] Since there is a first height difference between the upper and lower parts of the connecting plate, the lower part of the connecting plate cannot be fixed well when the connecting piece is fixed, resulting in low stability of the end of the long plate and easy vibration. Therefore, the axis of the connector is perpendicular to the axis of the connector, and the plug-in connector is located on the long plate near one end of the long plate. The position of the plug-in connector is set lower, and the plug-in connector and the connecting plate are fixed by the connecting piece, which can better fix the upper part of the connecting plate and the end of the long plate.

[0020] The long plate is connected to the bottom transverse support channel steel through the connecting plate and the connecting assembly, which is convenient for assembly and disassembly. It is not necessary to directly weld the two ends of the long plate to the ground rail and the bottom transverse support channel steel, thereby reducing the deformation of the long plate caused by welding and affecting the movement of the forklift. It can also be used for shelves in temporary warehouses, which is convenient for disassembly and installation, improves the rational use of connection unit components, and reduces the waste of resources.

[0033] See also Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a through-type rack floor rail connection structure is shown. The through-type rack 1 has multiple parallel transport channels 2, each of which is provided with a floor rail 3. The bottom of the through-type rack 1 is provided with a bottom transverse support channel steel 101 parallel to the floor rail 3. Both sides of the floor rail 3 along the width direction are connected to the adjacent bottom transverse support channel steel 101 through symmetrically arranged connection units, that is, the same floor rail 3 is connected to the bottom of the through-type rack 1 on both sides of the same transport channel 2 through two symmetrically arranged connection units.

[0034] See also Figure 3 As shown, a single connection unit includes an elongated plate 4 and a connection assembly. One end of the elongated plate 4 is detachably connected to the lower portion of the floor rail 3, and the other end is detachably connected to the bottom of the drive-through rack 1 via the connection assembly. The elongated plate 4 is arranged perpendicular to the floor rail 3. The thickness of the elongated plate 4 is less than 3 mm, and the lower surface of the elongated plate 4 is in close contact with the ground. Within this thickness range, the smooth movement of the forklift will not be affected.

[0035] See also Figure 5 、 Figure 6 and Figure 7 As shown, a connecting plate 5 is provided at one end of the elongated plate 4 near the bottom transverse supporting channel steel 101. The specific structure of the connecting plate 5 is as follows: since the bottom of the through-type rack 1 is provided with a bottom transverse supporting channel steel 101, in order to facilitate the connection and fixation of the bottom transverse supporting channel steel 101, the connecting plate 5 is provided as an L-shaped plate, including a long plate 501 and a short plate 502 connected vertically, the long plate 501 is provided vertically, the bottom end of the long plate 501 is fixedly connected to the elongated plate 4, the short plate 502 is fixedly connected to the upper end of the long plate 501, and the short plate 502 is located above the bottom transverse supporting channel steel 101, and one end of the connector 7 is plugged into and connected to the long plate 501.

[0036] See also Figure 8 and Figure 9As shown, the connection assembly includes a connector 6 and a plug connector 7. One end of the plug connector 7 passes through the lower portion of the connecting plate 5 and into the interior of the bottom transverse support channel 101. The lower end of the connector 6 vertically passes through the upper portion of the connecting plate 5 and the bottom transverse support channel 101, and is removably connected to one end of the plug connector 7. The vertical spacing between the axis of the plug connector 7 and the upper surface of the elongated plate 4 is 3-10 mm. This range facilitates installation of the plug connector 7 and prevents the plug connector 7 from being too high.

[0037] See also Figure 9 As shown, one end of the plug-in connector 7 located inside the bottom transverse support channel steel 101 is provided with a plug-in hole 701 adapted to the connector 6. As for the specific structure of the plug-in hole 701, the inner wall of the plug-in hole 701 includes an internal thread section 7011 and a circular hole section 7012 distributed up and down. The inner diameter of the circular hole section 7012 is smaller than the inner diameter of the internal thread section 7011. The lower part of the connector 6 is provided with an external thread adapted to the internal thread section 7011. Since the plug-in connector 7 is plug-connected to the long plate 501 and the bottom transverse support channel steel 101, there is a gap between them, which may cause shaking. By threading the connector 6 with the internal thread section 7011 and the short plate 502, the connector 6 is threadedly connected. Continuing to tighten the connector 6 downwards can enable the connector 6 to push the plug-in connector 7 downwards, thereby preventing the plug-in connector 7 from shaking.

[0038] See also Figure 8 As shown, the specific structure of the connecting member 6 is as follows: the connecting member 6 includes a screw rod with a stopper 601 sleeved on the upper portion of the screw rod. The short plate 502 is provided with a threaded hole 5021 for the screw rod to pass through. The outer diameter of the stopper 601 is larger than the inner diameter of the threaded hole 5021. To facilitate accurate insertion of the screw rod into the insertion hole 701, the lower end of the screw rod is provided with a tapered tip 602.

[0039] If the connecting plate 5 is directly fixed to the bottom horizontal supporting channel steel 101 through the connecting piece 6, due to the first height difference between the upper and lower parts of the connecting plate 5, the lower part of the connecting piece 6 cannot be fixed well when the connecting piece 6 is fixed, resulting in low stability of the end of the elongated plate 4 and prone to vibration. For this reason, the axis of the connector is perpendicular to the axis of the connector 6, and the plug-in connector 7 is located at one end of the long plate 501 close to the long plate 4, and the position of the plug-in connector 7 is set lower. When the plug-in connector 7 and the connecting plate 5 are fixed through the connecting piece 6, the upper part of the connecting plate 5 and the end of the elongated plate 4 can be better fixed.
