Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel structure lifting platform construction technology, and in particular to a single-sided column-supported lifting platform structure. Background Technology
[0002] With the development of the construction industry, more and more roofs are adopting spatial steel truss structures. For steel truss structures with large spans and heights, especially for the lifting construction of roof steel trusses, building a lifting platform is one of the preferred methods for facilitating construction. Conventional lifting platforms are mostly full-span lifting frames, which are constructed by stacking multiple standard sections. However, some roof steel truss lifting construction operations are in complex environments, and conventional lifting platforms are difficult to adapt to the needs of the site. It is necessary to build a lifting platform that is suitable for the site environment. Some lifting platforms are built based on on-site columns, with the lifting platform erected on one side of the on-site column. The lifting platform is fixed to the on-site column by welding multiple fixed points on the web of the on-site column through connecting rods. However, when the lifting platform is disassembled, the on-site column is prone to cuts due to the cutting of connecting rods, which not only affects the appearance of the on-site column but also easily damages the column and affects the structural strength of the on-site column. Utility Model Content
[0003] The purpose of this utility model is to provide a single-sided column support lifting platform structure to solve the technical problems mentioned in the background art.
[0004] To achieve the above objectives, the present invention adopts the following technical solution:

The top surface of the pad beam is flush with the top of the rear column. The bottom surface of the platform beam is welded and fixed to the top of the rear column and the middle of the top surface of the pad beam. The end of the platform beam welded to the pad beam extends out of the pad beam. The hydraulic lifter is located at the end of the platform beam that extends out of the pad beam.
[0006] Furthermore, the first hoop has an ear plate on the outer side of its fixed end, a fixing screw on the ear plate, the fixing screw being hinged to the ear plate, and a fixing nut on the fixing screw. The second hoop has a limiting plate on the outer side of its fixed end, and a concave limiting opening is provided in the middle of the side of the limiting plate away from the second hoop. The width of the concave limiting opening is greater than the diameter of the fixing screw and less than the outer circumference width of the fixing nut. The length of the fixing screw is greater than the thickness of the limiting plate.
[0007] Furthermore, two anti-detachment limiting blocks are provided on both sides of the concave limiting opening and on the side of the limiting plate away from the ear plate, and the distance between the two anti-detachment limiting blocks is the same as the width of the concave limiting opening.
[0008] Furthermore, the ring-shaped clamp is provided with two positioning legs, and two lacing strips are respectively fitted onto the two positioning legs and welded and fixed to the ring-shaped clamp.
[0009] Furthermore, a third and a fourth lacing strip are respectively provided between the front column and the rear column, and between the pad beam and the rear column.

[0018] The embodiments described herein are specific implementations of this utility model, used to illustrate the concept of this utility model. They are all illustrative and exemplary, and should not be construed as limiting the implementation methods or scope of this utility model. In addition to the embodiments described herein, those skilled in the art can employ other obvious technical solutions based on the content disclosed in the claims and specification of this application. These technical solutions include those that make any obvious substitutions and modifications to the embodiments described herein.
[0019] This utility model discloses a single-sided column-supported lifting platform structure, such as... Figure 1 and Figure 2As shown, the system includes a support column 1, a support frame located on one side of the support column 1, and a hydraulic lifter 2 mounted on the support frame. The support frame includes a rear column 3 located at the top of the support column 1, two front columns 4 located on one side of the support column 1, and a platform beam 5 horizontally located at the top of the rear column 3 and the front columns 4. Both the front columns 4 and the rear column 3 are circular tubes. The rear column 3 is vertically fixed to the middle of the top of the support column 1. The two front columns 4 are vertically spaced apart, with the same distance between the two front columns 4 and the support column 1. Multiple sets of connecting rods 6 are provided between the front columns 4 and the support column 1, and these connecting rods 6 are vertically evenly spaced. Each set of connecting rods 6 includes a tie rod located between the two front columns 4 and a tie rod located between the two front columns 4 and the support column 1. Two lacing strips, lacing strip one and lacing strip two are both round tubes. Lacing strip one is horizontally fixedly connected between the two front columns 4, and lacing strip one and the two lacing strips two are arranged in a roughly triangular structure. The two lacing strips two are horizontally fixedly connected between the two front columns 4 and the support column 1, respectively. There is a gap between the connection ends of the two lacing strips two and the support column 1. The support column 1 is provided with multiple annular column clamps 7 at intervals. The annular column clamps 7 are provided with two positioning legs. The two lacing strips two are respectively fitted onto the two positioning legs and welded to the annular column clamps 7. The annular column clamps 7 include a first clamp body 701 and a second clamp body 702. The first clamp body 701 and the second clamp body 702 are both semi-annular structures with their annular openings facing each other. One end of the first clamp body 701 and one end of the second clamp body 702 are hinged by a pin. The ends of the first hoop 701 and the second hoop 702 furthest from the pin are fixed ends. An ear plate 9 is provided on the outer side of the fixed end of the first hoop 701, and a fixing screw 10 is provided on the ear plate 9. The fixing screw 10 is hinged to the ear plate 9, and a fixing nut 11 is provided on the fixing screw 10. A limiting plate 12 is provided on the outer side of the fixed end of the second hoop 702, perpendicular to the outer side of the fixed end of the second hoop 702. A concave limiting opening 13 is provided in the middle of the side of the limiting plate 12 furthest from the second hoop 702. The width of the concave limiting opening 13 is greater than the diameter of the fixing screw 10 and less than the outer circumference width of the fixing nut 11. The length of the fixing screw 10 is greater than the thickness of the limiting plate 12. Two anti-disengagement limiting openings are provided on both sides of the concave limiting opening 13 and on the side of the limiting plate 12 furthest from the ear plate 9. The spacing between the two anti-detachment limiting blocks 14 is the same as the width of the concave limiting opening 13. Therefore, after the fixing screw 10 is inserted into the concave limiting opening 13 and the fixing nut 11 is tightened, the two anti-detachment limiting blocks 14 block the outside of the fixing nut 11, preventing the fixing screw 10 from detaching from the concave limiting opening 13. When the annular column clamp 7 is connected and fixed to the support column 1, the first clamp body 701 and the second clamp body 702 are fitted onto the support column 1 at a predetermined position with their annular openings facing each other. After the fixing screw 10 is inserted into the concave limiting opening 13 of the limiting plate 12, the fixing nut 11 is tightened, fixing the fixing ends of the first clamp body 701 and the second clamp body 702 together. This fixes the annular column clamp 7 to the abdomen of the support column 1. The two positioning legs are welded and fixed to the outside of the annular column clamp 7.A horizontal support beam 8 is installed at the top of each of the two front columns 4. The support beam 8 is a box beam, and its length is greater than the distance between the two front columns 4. The bottom surface of the support beam 8 is welded and fixed to the top of both front columns 4. The top surface of the support beam 8 is flush with the top of the rear column 3. The platform beam 5 is a box beam, and its specifications are larger than those of the support beam 8. The bottom surface of the platform beam 5 is welded and fixed to the top of the rear column 3 and the middle of the top surface of the support beam 8. One end of the platform beam 5 welded to the support beam 8 extends beyond the outside of the support beam 8. A hydraulic lifter 2 is located at the end of the platform beam 5 that extends beyond the support beam 8. A connecting strip three and a connecting strip four are respectively installed between the front columns 4 and the rear column 3, and between the support beam 8 and the rear column 3. Both connecting strip three and the connecting strip four are round tubes. The two ends of connecting strip three are welded and fixed to the front column 4 and the rear column 3, respectively. The two ends of connecting strip four are welded and fixed to the support beam 8 and the rear column 3, respectively, thereby increasing the stability of the support frame.
[0020] This utility model utilizes a support frame located on one side of the supporting column and a hydraulic lifter mounted on the support frame. The support frame includes a rear column at the top of the supporting column, two front columns on one side of the supporting column, and a platform beam horizontally positioned at the top of the rear and front columns. Multiple ring-shaped clamps are spaced apart on the supporting columns, and two connecting strips are welded and fixed to the ring-shaped clamps. This allows for easy disassembly and fixation of the front and supporting columns during the lifting of steel structures in high-altitude and complex on-site environments, using one side of the supporting column as the leverage point. This creates a lifting platform that is low-cost, highly safe, adaptable to various sites, and highly stable. It avoids the situation where cutting the connecting strips during disassembly of the lifting platform causes cuts to the supporting column, affecting its appearance and damaging the column structure, thus reducing its structural strength.
