Description

Technical Field

[0001] This invention belongs to the field of shelving technology, specifically a heavy-duty drive-in shelving with a lateral support structure. Background Technology

[0002] Drive-in racking, as a high-density storage device, is widely used in logistics and warehousing because it maximizes the use of vertical and depth space in warehouses. In heavy-duty racking systems, the stability of the racking structure faces significant challenges due to the large weight of stored goods and frequent forklift operations. Current heavy-duty drive-in racking technologies typically rely primarily on a rigid connection between the bottom of the uprights and the ground to maintain vertical load-bearing capacity, with lateral stability often only ensured by increasing the upright wall thickness or adding a few simple diagonal braces.

[0003] However, existing heavy-duty drive-in racking technology has certain shortcomings. Warehouse floors where heavy-duty drive-in racking is placed may have construction errors, localized settlement, or slight slopes. This results in a small contact area between the bottom of the diagonal braces and the ground when the racking is laterally supported by diagonal braces, leading to overall racking instability. Additionally, the presence of pipelines, drainage ditches, or temporary storage on the ground may restrict the extension space of the lateral support members. Furthermore, the fixed shelf height of existing heavy-duty drive-in racking makes it difficult to place taller items onto the shelves. Summary of the Invention

[0004] This invention provides a heavy-duty drive-in rack with a lateral support structure, which solves the technical problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention provides a heavy-duty drive-in rack with a lateral support structure, including uprights, reinforcing ribs fixedly connected to the surface of the uprights, a support mechanism provided on the uprights, an upper frame fixedly connected to the upper end of the uprights, an mounting plate fixedly installed on the surface of the upper frame, an adjustment mechanism provided on the mounting plate, a bracket provided on the adjustment mechanism, and a tray fixedly connected to the upper end of the bracket.

[0006] Preferably, the lower end of the upright is fixedly connected to a mounting base, and the mounting base has multiple evenly distributed slotted holes inside. By setting the mounting base with slotted holes, the bolts can be adjusted within a certain displacement range of the slotted hole length when the shelf is connected to the ground, thus eliminating installation errors.

[0007] Preferably, the support mechanism includes a support sleeve, with the support sleeve mounted on the outer side of the upright via a bearing. A slide cylinder is hinged to the surface of the support sleeve, and a screw is slidably connected inside the slide cylinder. A screw cap is mounted on the outer side of the slide cylinder via a bearing, and the screw cap and screw are connected by threads. An anti-slip base is hinged to the end of the screw. By deflecting the slide cylinder relative to the support sleeve and rotating the screw cap and screw to perform threaded movement, the screw can extend from the slide cylinder, allowing the anti-slip base to contact the ground and provide auxiliary support to the upright, thus making the overall support of the device more stable. Moreover, by adjusting the deflection angle of the slide cylinder and its contact with the upright, the position of the anti-slip base can be adjusted, allowing for use on uneven ground and avoiding the influence of debris on the side support of the device, thereby providing uniform and reliable support for the shelf upright 1. The motor drives the active sprocket to rotate, which in turn drives the driven sprocket to rotate via a chain. This causes two adjusting rods to drive multiple threaded segments with different pitches to rotate synchronously, allowing the threaded segments to make threaded movements with the pressure plate. The pressure plate then elastically presses the support seat through a compression spring, causing multiple brackets to move the support plates. This changes the spacing between the support plates, allowing the device to hold objects of different heights, thus increasing its applicability.

[0008] Preferably, a square rod is fixedly connected inside the slide cylinder, and the square rod is slidably connected to the screw. The square rod guides the movement of the screw.

[0009] Preferably, the adjusting mechanism includes an adjusting rod, which is mounted inside the upper frame via a bearing. A driven sprocket is fixedly connected to the outer side of the adjusting rod. A motor is fixedly mounted at the upper center of the mounting plate. The motor's shaft passes through the mounting plate and is rotatably connected to it. A drive sprocket is fixedly connected to the lower end of the motor's shaft. A chain meshes with the outer side of the drive sprocket, and the chain meshes with the driven sprocket. The adjusting rod has multiple evenly distributed threaded segments, with the thread pitch decreasing sequentially from top to bottom. A support seat is movably connected to the outer side of each threaded segment. The support seat is fixedly connected to a bracket. A pressure plate is threadedly connected to the outer side of each threaded segment. The pressure plate is slidably connected to a column. A compression spring is provided on the outer side of each threaded segment. The motor drives the active sprocket to rotate, which in turn drives the driven sprocket to rotate via a chain. This causes two adjusting rods to drive multiple threaded segments with different pitches to rotate synchronously, allowing the threaded segments to make threaded movements with the pressure plate. The pressure plate then elastically presses the support seat through a compression spring, causing multiple brackets to move the support plates. This changes the spacing between the support plates, allowing the device to hold objects of different heights, thus increasing its applicability.

[0010] Preferably, the lower end of the mounting plate is provided with a guide wheel, which contacts the chain. The guide wheel limits the movement of the chain.

[0011] Preferably, one end of the compression spring is fixedly connected to the support base, and the other end of the compression spring is fixedly connected to the pressure plate. The compression spring provides elastic support to the support base.

[0012] Preferably, a guide sleeve is fixedly connected to the surface of the bracket, and the guide sleeve is slidably connected to the column. By setting the guide sleeve, the movement of the bracket is guided, avoiding uneven local force on the bracket and preventing it from overturning.

[0013] Compared with related technologies, the heavy-duty drive-in rack with a lateral support structure provided by the present invention has the following advantages: First, by deflecting the slide cylinder relative to the support sleeve and rotating the screw cap and screw to create a threaded motion, the screw can extend from the slide cylinder, allowing the anti-slip base to contact the ground and provide auxiliary support to the uprights, making the overall support of the device more stable. Moreover, by varying the deflection angle of the slide cylinder and its contact with the uprights, the position of the anti-slip base can be adjusted, making it suitable for use on uneven ground and avoiding the impact of debris on the side support of the device, thus providing uniform and reliable support for the shelf uprights.

[0014] Secondly, the motor drives the active sprocket to rotate, which in turn drives the driven sprocket to rotate via a chain. This causes the two adjusting rods to drive multiple threaded segments with different pitches to rotate synchronously, allowing the threaded segments to make threaded movements with the pressure plate. This causes the pressure plate to elastically press the support seat through a compression spring, which in turn causes multiple brackets to move the trays, resulting in changes in the spacing between the trays. This allows the device to place objects of different heights, making the device more versatile. Attached Figure Description

[0017] Please see Figure 1-8 A heavy-duty drive-in rack with a lateral support structure includes an upright 1, a reinforcing rib 2 fixedly connected to the surface of the upright 1, a support mechanism 3 provided on the upright 1, an upper frame 4 fixedly connected to the upper end of the upright 1, an mounting plate 5 fixedly installed on the surface of the upper frame 4, an adjustment mechanism 6 provided on the mounting plate 5, a bracket 7 provided on the adjustment mechanism 6, a support plate 8 fixedly connected to the upper end of the bracket 7, and a mounting base 11 fixedly connected to the lower end of the upright 1. The mounting base 11 has multiple evenly distributed waist holes inside. By setting the mounting base 11 with waist holes, when the rack is connected to the ground, the bolts can be adjusted within a certain displacement range of the waist hole length, eliminating installation errors.

[0018] The support mechanism 3 includes a support sleeve 31. The support sleeve 31 is mounted on the outer side of the column 1 via bearings. A slide cylinder 32 is hinged to the surface of the support sleeve 31. A screw 33 is slidably connected inside the slide cylinder 32. A square rod 34 is fixedly connected inside the slide cylinder 32, and the square rod 34 and the screw 33 are slidably connected. The square rod 34 guides the movement of the screw 33. A screw cap 35 is mounted on the outer side of the slide cylinder 32 via bearings. The screw cap 35 and the screw 33 are threadedly connected. An anti-slip base 36 is hinged to the end of the screw 33. By deflecting the slide cylinder 32 relative to the support sleeve 31 and rotating the screw cap 35 and the screw 33 to perform threaded movement, the screw 33 can extend from the slide cylinder 32, allowing the anti-slip base 36 to contact the ground and provide auxiliary support to the column 1, thus making the overall support of the device more stable. Furthermore, by adjusting the deflection angle of the slide cylinder 32 and its contact with the upright 1, the position of the anti-slip base 36 can be adjusted. This allows for use on uneven ground and avoids the side support of the device being affected by debris on the ground, thus providing uniform and reliable support for the shelf upright 1. The motor 63 drives the drive sprocket 64 to rotate, which in turn drives the driven sprocket 62 to rotate via the chain 65. This causes the two adjusting rods 61 to drive multiple threaded segments 67 with different pitches to rotate synchronously, allowing the threaded segments 67 to perform threaded motion with the pressure plate 69. The pressure plate 69 then elastically presses the support seat 68 via the compression spring 610, causing multiple brackets 7 to move the trays 8. This changes the spacing between the trays 8, allowing the device to place objects of different heights, thus increasing its applicability.

[0019] The adjustment mechanism 6 includes an adjustment rod 61, which is mounted inside the upper frame 4 via bearings. A driven sprocket 62 is fixedly connected to the outer side of the adjustment rod 61. A motor 63 is fixedly mounted at the upper center of the mounting plate 5. The shaft of the motor 63 passes through the mounting plate 5 and is rotatably connected to it. A drive sprocket 64 is fixedly connected to the lower end of the motor 63's shaft. A chain 65 meshes with the outer side of the drive sprocket 64. A guide wheel 66 is provided at the lower end of the mounting plate 5. The guide wheel 66 contacts the chain 65, limiting the chain 65. The chain 65 meshes with the driven sprocket 62. The adjusting rod 61 has multiple evenly distributed threaded sections 67, with the thread pitch decreasing from top to bottom. A support seat 68 is movably connected to the outer side of each threaded section 67, and the support seat 68 is fixedly connected to the bracket 7. A pressure plate 69 is threadedly connected to the outer side of each threaded section 67, and the pressure plate 69 slides against the column 1. The connection includes a compression spring 610 on the outer side of the threaded section 67. One end of the compression spring 610 is fixedly connected to the support base 68, and the other end is fixedly connected to the pressure plate 69. The compression spring 610 provides elastic support to the support base 68. A guide sleeve 611 is fixedly connected to the surface of the bracket 7 and is slidably connected to the column 1. The guide sleeve 611 guides the movement of the bracket 7, preventing uneven force on the plate 8 from causing it to flip. The motor 63 drives the drive sprocket 64 to rotate, which in turn drives the driven sprocket 62 to rotate via the chain 65. This causes the two adjusting rods 61 to drive multiple threaded sections 67 with different pitches to rotate synchronously, allowing the threaded sections 67 to perform threaded motion with the pressure plate 69. The pressure plate 69 then elastically presses the support base 68 through the compression spring 610, causing multiple brackets 7 to move the plate 8. This changes the distance between the plates 8, allowing the device to hold objects of different heights, thus increasing its applicability.

[0020] The invention is used as follows: During installation, the mounting base 11 contacts the ground, and the device is fixed by bolts passing through the slots on the mounting base 11. Then, the support sleeve 31 is manually rotated, causing the slide cylinder 32 to deflect. The slide cylinder 32 causes the screw 33 to change angle, and then the screw cap 35 is rotated. The screw cap 35 rotates, and the screw 33 moves in a threaded motion, causing the screw 33 to slide outside the square rod 34. This causes the screw 33 to move the anti-slip base 36, keeping the anti-slip base 36 in contact with the ground. By deflecting the slide cylinder 32 relative to the support sleeve 31 and by rotating the screw cap 35 and causing the screw 33 to move in a threaded motion, the screw 33 can extend out of the slide cylinder 32, allowing the anti-slip base 36 to contact the ground and provide auxiliary support to the column 1, making the overall support of the device more stable. Moreover, by adjusting the deflection angle of the slide cylinder 32 and by having the slide cylinder 32 in contact with the column 1, the position of the anti-slip base 36 can be adjusted, which can be used for local unevenness. This device is designed for ground use and avoids interference from debris on the ground, providing uniform and reliable support for the rack uprights. The spacing between pallets 8 is adjusted according to the size of the goods placed on them. The motor 63 is started, driving the drive sprocket 64 to rotate. This, in turn, drives the driven sprocket 62 via the chain 65. The driven sprocket 62 then drives the adjusting rod 61 to rotate, causing the two adjusting rods 61 to simultaneously rotate multiple threaded segments 67 with different pitches. This allows the threaded segments 67 to move in a threaded motion with the pressure plate 69, causing the pressure plate 69 to move. Because the threaded segments 67 have different pitches, the pressure plate 69 moves upwards by different distances. The pressure plate 69 then drives the compression spring 610 to move upwards, which elastically compresses the support seat 68. The support seat 68 then moves the bracket 7, which in turn moves the multiple brackets 7, causing the pallets 8 to move. This changes the spacing between the pallets 8, allowing the device to accommodate objects of varying heights, thus increasing its versatility.
