The device has a stable structure and a high safety factor; it is applicable to I-beams of various sizes and has strong versatility; it can achieve smooth transport of I-beams without damaging the I-beams and steel wire, exhibiting high reliability.

[0004] However, existing pallet racks have a fixed width. When they need to carry long goods, the fixed width of the pallet rack can easily cause the center of gravity to shift, resulting in the goods tipping over.

[0005] Therefore, the adjustable handling rack needs to be redesigned and modified. Utility Model Content

[0006] The purpose of this invention is to solve the problem that in the existing technology, the width of the transport rack is fixed. When it needs to carry long goods, the fixed width of the transport rack is prone to the phenomenon of center of gravity shift, which leads to the tipping of the goods. Therefore, an adjustable transport rack is proposed.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An adjustable transport bracket includes a frame, a load-bearing plate is drivenly connected to the top of the frame, and supports are fixedly connected to both sides of the top of the load-bearing plate. An adjustment block is installed on the surface of the load-bearing plate through an adjustment structure. The adjustment block is located outside the supports, and the adjustment structure can adjust the spacing of the supports to extend outward.

[0009] As a preferred technical solution of this application, the adjustment structure includes a bidirectional screw that is movably connected to the surface of the bearing plate via a bearing. Both sides of the surface of the bidirectional screw are threaded with a screw sleeve. Both sides of the bottom of the screw sleeve are movably connected with a crank via a pin. The side of the crank away from the screw sleeve extends to the bottom of the adjustment block and is movably connected to the adjustment block via a pin.

[0010] As a preferred technical solution of this application, the rear end of the bidirectional screw passes through the bearing plate and extends to the rear side of the bearing plate. A rotating wheel is provided at the top of the bearing plate, and a transmission rod is fixedly connected to the bottom of the rotating wheel. The end of the transmission rod away from the rotating wheel passes through the bearing plate and extends into the interior of the bearing plate. Helical gears are fixedly connected to both the bottom end of the transmission rod and the rear end of the bidirectional screw, and the helical gears mesh with each other.

[0011] As a preferred technical solution of this application, rollers are embedded on both sides of the top of the screw sleeve. The rollers are movably connected to the screw sleeve through pins, and the rollers can rotate and roll.

[0012] As a preferred technical solution of this application, a support plate is fixedly connected to the surface of the bearing plate, and the side of the support plate away from the bearing plate extends to the front side of the bidirectional screw and is movably connected to the bidirectional screw through a bearing.

[0013] As a preferred technical solution of this application, a baffle is provided on the outer side of the adjusting block, and adjusting grooves are provided on both sides of the surface of the baffle. A bolt located inside the adjusting groove is threadedly connected to the outer side of the adjusting block, and the bolt and the adjusting groove are slidably connected.

[0014] Compared with the prior art, the present invention provides an adjustable transport bracket, which has the following advantages:

[0015] 1. This adjustable transport rack dynamically adjusts the spacing between the two side adjustment blocks through the adjustment structure, allowing it to extend outwards to accommodate goods of different lengths. This design breaks through the limitations of traditional fixed-width transport racks, avoids center of gravity shift due to excessively long goods, effectively prevents tipping problems, and improves transport stability and safety.

[0016] 2. This adjustable transport bracket adopts a mechanical transmission structure with a two-way screw and a screw sleeve, combined with a crank mechanism, to convert the rotational motion of the screw into the lateral linear motion of the adjusting block. The reverse threads on both sides of the two-way screw enable the adjusting blocks on both sides to move synchronously and symmetrically, ensuring the uniformity and stability of the spacing adjustment. The operation process is controllable and the transmission efficiency is high.

[0017] 3. This adjustable transport bracket transmits power through a rotating wheel-driven helical gear set, allowing the operator to directly control the rotation of the bidirectional screw from the top of the support plate. The helical gear meshing structure converts vertical rotation into horizontal screw rotation, simplifying the operation path, avoiding the tediousness of manually adjusting the screw, and improving the convenience and labor-saving of operation.

[0018] 4. This adjustable handling bracket has rollers on the top of the screw sleeve, which reduces the frictional resistance between the screw sleeve and the surface of the goods when the screw sleeve moves, making the adjustment process smoother, reducing wear, and the rollers can rotate freely with the movement of the screw sleeve to avoid jamming, extend the service life of the screw and screw sleeve, and enhance the durability of the adjustment structure.

[0019] 5. This adjustable transport bracket uses a support plate and bearings to fix the front end of the bidirectional screw, preventing radial offset or vibration caused by uneven force during rotation of the bidirectional screw, and ensuring the thread fit accuracy between the bidirectional screw and the screw sleeve. This design improves the rigidity of the transmission structure and enhances the stability and reliability of the adjustment process.

[0020] 6. This adjustable handling bracket is slidably connected to the adjustment groove by bolts through the baffle on the outside of the adjustment block. The position of the baffle can be flexibly adjusted according to the adjusted spacing of the adjustment blocks, providing lateral restraint for goods of different widths. The adjustment groove allows the bolts to slide and then lock, which not only adapts to the change of spacing, but also prevents the goods from sliding laterally during transportation, further improving the fixing effect.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0027] Example:

[0028] Reference Figure 1-4 An adjustable transport rack includes a frame 1, with a load-bearing plate 2 connected to the top of the frame 1. Supports 3 are fixedly connected to both sides of the top of the load-bearing plate 2. Adjusting blocks 5 are mounted on the surface of the load-bearing plate 2 via an adjustment structure 4, located outside the supports 3. The adjustment structure 4 can adjust the spacing of the supports 3 to extend outwards. By dynamically adjusting the spacing of the two adjusting blocks 5, it can extend outwards to accommodate goods of different lengths. This design overcomes the limitations of traditional fixed-width transport racks, avoiding center of gravity shift due to excessive cargo length, effectively preventing tipping, and improving transport stability and safety. The adjustment structure 4 includes a bidirectional screw 6 movably connected to the surface of the load-bearing plate 2 via bearings. Screw sleeves 7 are threaded to both sides of the surface of the bidirectional screw 6. Cranks 8 are movably connected to both sides of the bottom of the screw sleeves 7 via pins. The side of the crank 8 away from the screw sleeves 7 extends to the bottom of the adjusting block 5 and is movably connected to the adjusting block 5 via a pin. Next, the rear end of the bidirectional screw 6 passes through the support plate 2 and extends to the rear side of the support plate 2. A rotating wheel 9 is provided on the top of the support plate 2. A transmission rod 10 is fixedly connected to the bottom of the rotating wheel 9. The end of the transmission rod 10 away from the rotating wheel 9 passes through the support plate 2 and extends into the interior of the support plate 2. The bottom end of the transmission rod 10 and the rear end of the bidirectional screw 6 are both fixedly connected to helical gears 11. The helical gears 11 mesh with each other. Rollers 12 are embedded on both sides of the top of the screw sleeve 7. The rollers 12 are movably connected to the screw sleeve 7 through pins. The rollers 12 can rotate and roll. A support plate 13 is fixedly connected to the surface of the support plate 2. The side of the support plate 13 away from the support plate 2 extends to the front side of the bidirectional screw 6 and is movably connected to the bidirectional screw 6 through a bearing. A baffle 14 is provided on the outer side of the adjusting block 5. An adjusting groove 15 is provided on both sides of the surface of the baffle 14. A bolt 16 located inside the adjusting groove 15 is threadedly connected to the outer side of the adjusting block 5. The bolt 16 and the adjusting groove 15 are slidably connected.

[0029] Specifically, during operation / use, this adjustable transport rack features a load-bearing plate 2 mounted on the top of its frame 1, with fixed supports 3 on both sides to support the goods. Traditional transport racks, due to their fixed width, are prone to center of gravity shift and tipping when carrying excessively long goods. The spacing of the adjusting blocks 5 is dynamically adjusted by the adjusting structure 4 to accommodate different goods lengths. The operator rotates the wheel 9 on top of the load-bearing plate 2, which drives the connected transmission rod 10 to rotate. The helical gear 11 at the bottom of the transmission rod 10 meshes with the helical gear 11 at the rear end of the double-ended screw 6, transmitting the rotational motion to the double-ended screw 6, causing it to rotate around its axis. The threads on both sides of the bidirectional screw 6 are in opposite directions. When the screw rotates, the sleeves 7 on both sides move linearly in opposite directions along the screw. The rollers 12 on the top of the sleeves 7 contact the bottom of the goods, reducing friction through rolling and ensuring smooth movement. The bottom of each sleeve 7 is connected to a pair of cranks 8 by a pin. As the sleeve 7 moves, the cranks 8 rotate around the pin, converting the longitudinal linear motion of the sleeve 7 into the lateral movement of the adjusting block 5. The end of the cranks 8 is connected to the bottom of the adjusting block 5 by a pin, pushing the adjusting block 5 to expand outward or contract inward. Its lateral movement directly changes the distance between the two adjusting blocks 5. When the bidirectional screw 6 rotates clockwise or counterclockwise, the distance between the supports 3 increases or decreases, thereby adapting to goods of different lengths and preventing the center of gravity from shifting. The adjusting groove 15 of the baffle 14 allows the bolts 16 to slide in the groove. By tightening the bolts 16, the position of the baffle 14 can be locked to adapt to the adjusted distance between the supports 3. The goods are placed between the two supports 3, with the baffle 14 providing lateral support to ensure stability during transportation.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
