[0002] Lightweight hoisting equipment can be used to hoist lightweight construction materials, and is especially suitable for roof hoisting operations of small self-built buildings.

[0003] Existing lightweight lifting equipment has a fixed support structure that cannot rotate, making it impossible to adjust the lifting angle and move the lifted goods horizontally. Furthermore, the support is designed as a single piece, making it difficult to achieve modular and rapid assembly. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the inability of the support to rotate and the difficulty in quickly assembling the support into separate parts, and to propose a parapet wall clamping rotatable electric hoisting device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Design a parapet wall clamping rotatable electric hoisting device, including a hoisting motor, and further comprising: An adjustable clamping assembly includes a first clamping plate and a second clamping plate. Both the first clamping plate and the second clamping plate are L-shaped structures. The first clamping plate and the second clamping plate are fixed together by a combination of multiple sets of first bolts. A support plate is welded to the side end face of the first clamping plate. The rotating hoisting assembly includes a first support column and a second support column. The second support column is slidably sleeved on the upper end of the first support column, and the lower end of the first support column is movably inserted into the interior of the support plate. A hoisting rod is welded to the upper end of the second support column, and the hoisting motor is fixedly installed on one side of the hoisting rod.

[0006] Preferably, two sets of support plates are provided above and below, the support plates are cylindrical structures, and a third bolt is threaded on the outer wall of the support plates, the third bolt abutting against the outer surface of the first support column.

[0008] Preferably, a collar is also sleeved around the second support column, and the collar is fixed to a set of through holes by inserting a rod. A reinforcing rod is connected between the collar and the suspension rod to strengthen the suspension rod.

[0009] Preferably, the side end face of the first clamping plate is also threaded with multiple sets of second bolts, which are used to abut against the external wall.

[0010] Preferably, rubber pads are fitted on the inner sides of both the second clamping plate and the wall, and the second bolt abuts against the wall through the rubber pads.

[0011] The parapet wall clamping rotatable electric hoisting device proposed in this utility model has the following advantages: The first clamping plate and the second clamping plate can be used to clamp the wall, thereby fixing the main body, and are easy to disassemble and assemble.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0015] Example 1 Reference Figures 1-4 A parapet wall clamping rotatable electric hoisting device includes a hoisting motor 13, and further includes: Adjustable clamping assembly, see reference Figure 2 The adjustable clamping assembly includes a first clamping plate 1 and a second clamping plate 2. Both the first clamping plate 1 and the second clamping plate 2 are L-shaped structures. The first clamping plate 1 and the second clamping plate 2 are fixed together by multiple sets of first bolts 3. A support plate 5 is welded to the side end face of the first clamping plate 1. Rotating hoisting assembly, refer to Figure 3 , Figure 4 The rotating hoisting assembly includes a first support column 7 and a second support column 8. The second support column 8 is slidably sleeved on the upper end of the first support column 7. The lower end of the first support column 7 is movably inserted into the interior of the support plate 5. A hoisting rod 12 is welded to the upper end of the second support column 8. The hoisting motor 13 is fixedly installed on one end of the outer side of the hoisting rod 12.

[0016] Furthermore, refer to Figure 1 , Figure 2 The support plate 5 is provided in two sets, one above the other. The support plate 5 is a cylindrical structure. The outer wall of the support plate 5 is threaded with a third bolt 6, which abuts against the outer surface of the first support column 7. Furthermore, refer to Figure 3 , Figure 4 A rotating frame 10 is fitted around the second support column 8. Multiple sets of through holes 9 are opened through the outer wall of the second support column 8. The rotating frame 10 is fixed to a set of through holes 9 by inserting a rod 11. The bottom end of the rotating frame 10 slides in contact with the top end of the first support column 7. A bearing is provided at the bottom of the rotating frame 10 to reduce the friction between the rotating frame 10 and the first support column 7. Furthermore, refer to Figure 3 , Figure 4 The second support column 8 is also fitted with a collar 14. The collar 14 is fixed to a set of through holes 9 by inserting a rod 11. A reinforcing rod 15 is connected between the collar 14 and the hanger rod 12 to strengthen the strength of the hanger rod 12.

[0017] Furthermore, refer to Figure 1 , Figure 2 The side end face of the first clamping plate 1 is also threaded with multiple sets of second bolts 4, which are used to abut against the external wall. Furthermore, rubber pads are fitted on the inner sides of both the second clamping plate 1 and the second clamping plate 2. The second bolt 4 abuts against the wall through the rubber pads. The rubber pads are used to increase the friction between the second bolt 4 and the wall, thereby improving stability.

[0018] Working principle: During assembly, the first clamping plate 1 and the second clamping plate 2 are positioned opposite each other, with the first clamping plate 1 facing the inner side of the wall and the second clamping plate 2 facing the outer side of the wall. First, the first clamping plate 1 and the second clamping plate 2 are fixed with suitable threaded holes selected by multiple sets of first bolts 3 to roughly match the wall thickness. When installing the first bolts 3, the downward extension of the first bolts 3 can be used to make the first clamping plate 1 and the second clamping plate 2 horizontal relative to the direction of gravity, avoiding tilting due to unevenness at the top of the wall. The second bolt 4 is then combined with the first clamping plate 1 and rotated until the second bolt 4 abuts against the wall surface to precisely match the wall thickness, further improving the supporting strength of the first clamping plate 1 and the second clamping plate 2 on the wall.

[0019] Fit the collar 14 and the rotating frame 10 around the second support column 8. Then insert the second support column 8 into the first support column 7. Adjust the first support column 7 and the second support column 8 to the required extension length. Then, abut the top of the rotating frame 10 against the first support column 7 and fix the rotating frame 10 to the through hole 9 on the second support column 8 through the insertion rod 11. The rotating frame 10 prevents the second support column 8 from sliding downwards inside the first support column 7 and allows the first support column 7 and the second support column 8 to rotate. Fix the collar 14 to the through hole 9 on the second support column 8 through the insertion rod 11. Connect the two ends of the reinforcing rod 15 to the collar 14 and the hanging rod 12 respectively with bolts. Finally, insert the first support column 7 into the support plate 5 and rotate the third bolt 6 so that the third bolt 6 abuts against the outer surface of the first support column 7. The installation is now complete.

[0020] In use, the goods are lifted by the lifting cable in the lifting motor 13, and then the second support column 8 is rotated. At this time, the second support column 8 drives the rotating frame 10 to rotate. The bottom of the rotating frame 10 rotates with the top of the first support column 7, thus realizing the lifting, rotating and transferring of the goods.

[0021] 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.
