Description

Technical Field

[0001] This utility model relates to the field of adjustment device technology, and in particular to a convenient elevation adjustment device for a hanging basket steel sling. Background Technology

[0002] Currently, using hanging baskets for cantilever casting of the superstructure of continuous beam bridges is a very common construction method. Traditionally, hanging baskets use precision-rolled threaded steel bars to transfer vertical loads, but these bars are prone to breakage and safety accidents. Relevant national departments have explicitly prohibited the use of precision-rolled threaded steel bars as hanging basket suspension rods in non-perforated locations. Instead, steel slings are used to replace precision-rolled threaded steel bars for load-bearing. On construction sites, thick steel plates are commonly perforated at 100mm intervals, using pins for load-bearing. The minimum adjustment interval is 100mm, making it impossible to adjust to arbitrary elevations like precision-rolled threaded steel bars. Therefore, construction sites often use jacks to lift the basket and then place steel plates under the pins, repeatedly testing with steel plates of varying thicknesses to achieve a precise elevation. However, excessively high supports result in poor stability, are time-consuming and labor-intensive, and pose safety risks. In view of this, this utility model proposes a convenient elevation adjustment device for hanging basket steel slings. Utility Model Content

[0003] The purpose of this utility model is to address the problems in the background technology where construction sites often use jacks to lift the load and then place steel plates under the pins to achieve a precise elevation through multiple trial placements of steel plates of varying thicknesses. However, this method suffers from issues such as poor stability, time-consuming and labor-intensive work, and poor safety when the support is too high. This invention proposes a convenient elevation adjustment device for hanging basket steel slings.

[0004] The technical solution of this utility model is as follows: A convenient elevation adjustment device for a hanging basket with a steel sling, comprising a steel sling with multiple sets of lifting holes equidistantly arranged on the steel sling, and an adjustment mechanism slidably sleeved on the steel sling. The adjustment mechanism includes an adjustment steel box slidably connected to the steel sling, with a semi-circular groove on the top of the adjustment steel box, and a pin installed at the position of the semi-circular groove, the pin passing through a set of lifting holes; and a positioning component installed on the side of the adjustment mechanism, the positioning component being used to position the adjustment mechanism.

[0005] Optionally, the adjustment mechanism further includes two sets of supporting steel plates fixedly connected to both sides of the adjustment steel box. Each set of supporting steel plates is provided with an adjusting fine-rolled threaded steel bar. A fixing nut is fixedly connected to the adjusting fine-rolled threaded steel bar and the fixing nut is fixedly connected to the bottom of the supporting steel plate.

[0006] Optionally, the adjusting fine-rolled threaded steel bar is threaded with at least one set of adjusting nuts, and a supporting steel pad is provided below the adjusting nuts. A connecting steel plate is fixedly connected to the bottom of the supporting steel pad, and two sets of channel steel supports are fixedly connected to the bottom of the two sets of connecting steel plates. The adjusting steel box is slidably connected between the two sets of channel steel supports.

[0007] Optionally, multiple sets of stiffening plates are fixedly connected between the supporting steel plate and the adjusting steel box.

[0008] Optionally, the supporting steel plate has a first through hole, the diameter of which is larger than the diameter of the adjustable fine-rolled threaded steel.

[0009] Optionally, the supporting steel pad and the connecting steel plate are provided with a second through hole, the diameter of which is larger than the diameter of the adjusting fine-rolled threaded steel.

[0010] Optionally, the positioning component includes a fixing plate fixedly connected to the side of the channel steel bracket, a fixing nut fixedly connected to the side of the fixing plate, a bolt threadedly connected to the fixing nut, a positioning plate provided on the bolt, a sliding hole provided on the positioning plate, the bolt slidably connected at the position of the sliding hole, a washer provided between the head of the bolt and the positioning plate, and the washer being sleeved on the outer ring of the bolt.

[0011] Optionally, a third through hole is provided on the fixing plate at the position corresponding to the fixing nut, and the diameter of the third through hole is larger than the diameter of the bolt.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This utility model, through the setting of the adjustment mechanism, only requires two adjusting fine-rolled threaded steel bars to adjust the elevation of the steel sling. The force is clear. The load is transferred to the adjusting steel box through the pin shaft, then to the adjusting fine-rolled threaded steel bars, then to the supporting steel pad, connecting steel plate and channel steel bracket, and finally to the front upper crossbeam. The adjustment accuracy is high. At the same time, the device also makes full use of the advantage of the adjusting fine-rolled threaded steel bars having stronger tensile properties than compressive properties.

[0014] The components of the further adjustment mechanism are fixed by welding, which does not require special materials. The welding precision requirements are not high. The pins, adjusting fine-rolled threaded steel bars, fixing nuts and adjusting nuts are all purchased finished products. The device is easy to assemble and has low operation difficulty.

[0015] In summary, this utility model can meet the needs of most conventional hanging basket steel sling elevation adjustment applications. It is easy to operate, lightweight, and has high adjustment accuracy during use, making it highly applicable. Attached Figure Description

[0029] Example

[0030] like Figures 1 to 4 As shown, the present invention proposes a convenient elevation adjustment device for a hanging basket steel sling, which includes a steel sling 1. Multiple sets of lifting holes 11 are equally spaced on the steel sling 1. This is an existing structure and will not be described in detail here.

[0031] Furthermore, the aforementioned adjustment device includes an adjustment mechanism 2 slidably mounted on the steel sling 1. The adjustment mechanism 2 includes an adjustment steel box 21 slidably connected to the steel sling 1. A semi-circular groove 22 is provided on the top of the adjustment steel box 21, and a pin 23 is installed at the position of the semi-circular groove 22. The semi-circular groove 22 is used to position the pin 23 and prevent it from sliding. The pin 23 passes through a set of lifting holes 11, thereby contacting the lifting holes 11 for support, thus adjusting the height of the steel sling 1 when adjusting the position of the adjustment steel box 21. The adjustment mechanism 2 also includes two sets of supporting steel plates 24 welded to both sides of the adjustment steel box 21. Two sets of stiffening plates 211 are welded between the supporting steel plates 24 and the adjustment steel box 21. The stiffening plates 211 are used to strengthen the structure, so that when the supporting steel plates 24 move, they drive the adjustment steel box 21 to move synchronously. Both sets of supporting steel plates 24 are fitted with adjusting fine-rolled threaded steel bars 25. A first through hole 241 is opened on the supporting steel plate 24, which is opened before welding to facilitate the opening operation. The diameter of the first through hole 241 is larger than the diameter of the adjusting fine-rolled threaded steel bar 25, which helps to reduce the precision required for opening the first through hole 241, allowing it to be used within a certain error range. A fixing nut 26 is welded to the adjusting fine-rolled threaded steel bar 25, and the fixing nut 26 is welded to the bottom of the supporting steel plate 24. The fixed position of the fixing nut 26 fixes the position of the adjusting fine-rolled threaded steel bar 25. A set of adjusting nuts 27 are threadedly connected to the adjusting fine-rolled threaded steel bar 25. The adjusting nuts 27 move along their own length direction, i.e., up and down, when rotated. A supporting steel plate 28 is provided below the adjusting nut 27. A connecting steel plate 29 is welded to the bottom of the supporting steel plate 28. A second through hole 281 is opened on both the supporting steel plate 28 and the connecting steel plate 29. The diameter of the second through hole 281 is larger than the diameter of the adjusting fine-rolled threaded steel 25. The second through hole 281 is opened before welding to facilitate the opening operation and to reduce the accuracy of the opening of the second through hole 281. It can be used within a certain error range. Two sets of channel steel supports 210 are welded to the bottom of the two sets of connecting steel plates 29. The two sets of channel steel supports 210 are connected into a whole by the two sets of connecting steel plates 29. The supporting steel plate 28 is used to strengthen the structure. The adjusting steel box 21 is slidably connected between the two sets of channel steel supports 210, and at the same time, it prevents the adjusting steel box 21 from rotating.

[0032] Furthermore, the aforementioned adjustment device also includes a positioning component 3 installed on the side of the adjustment mechanism 2, which is used to position the adjustment mechanism 2. The positioning component 3 includes a fixing plate 31 welded to the side of the channel steel bracket 210, and the position of the fixing plate 31 is fixed. A fixing nut 32 is welded to the side of the fixing plate 31, and the position of the fixing nut 32 is also fixed. A bolt 33 is threaded into the fixing nut 32, and the bolt 33 moves along its own length direction when rotated. A positioning plate 34 is provided on the bolt 33, and a sliding hole 35 is opened on the positioning plate 34. The bolt 33 is slidably connected to the position of the sliding hole 35. A washer 36 is provided between the head of the bolt 33 and the positioning plate 34. The washer 36 is sleeved on the outer ring of the bolt 33. The washer 36 is used to increase the force-bearing area, so that after the bolt 33 is tightened, it drives the positioning plate 34 to press against the upper front crossbeam, thereby fixing the position of the adjustment mechanism 2. A third through hole 311 is provided on the fixing plate 31 at the position corresponding to the fixing nut 32. The diameter of the third through hole 311 is larger than the diameter of the bolt 33. The third through hole 311 is opened before welding to facilitate the opening operation and at the same time to reduce the accuracy of the opening of the third through hole 311. It can be used within a certain error range.

[0033] Specifically, depending on the direction of the front upper crossbeam, the direction of the fixing plate 31 can also be perpendicular to the adjusting steel box 21 and welded to the side of the channel steel bracket 210, so that the positioning plate 34 can clamp the front upper crossbeam.

[0034] In this embodiment, after the device is welded, the steel sling 1 is inserted into the adjusting steel box 21. After the channel steel bracket 210 is placed on the upper front crossbeam, the bolt 33 is rotated, causing the bolt 33 to move the washer 36 and press against the positioning plate 34. This brings the positioning plate 34 closer to the upper front crossbeam and presses it against the beam, fixing the channel steel bracket 210 to the upper front crossbeam and preventing it from moving. The pin 23 is inserted into a set of lifting holes 11, and the adjusting nut 27 is rotated. When the adjusting nut 27 rotates, it causes the adjusting fine-rolled threaded steel 25, which meshes with it, to move downward. As the adjusting fine-rolled threaded steel 25 moves, it causes the supporting steel plate 24 to move downward. At this time, the adjusting steel box 21 slides downward between the two sets of channel steel brackets 210, so that the steel sling 1 moves downward under the influence of gravity. At the same time, the adjusting nut 27 can be rotated in the opposite direction, causing the adjusting fine-rolled threaded steel 25 to move upward, thereby causing the supporting steel plate 24 and the adjusting steel box 21 to move upward, which in turn causes the steel sling 1 to move upward. This allows for the adjustment of the height of the steel sling 1 with high precision and strong applicability.

[0035] The above specific embodiments are merely optional embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
