Description

Technical Field

[0001] This utility model belongs to the field of building construction technology, specifically relating to an adjustable tower support device for an internal climbing tower crane. Background Technology

[0002] Currently, when civil engineering construction requires work inside a building, internal climbing tower cranes that ascend with the building are typically used. After the internal climbing tower crane has completed its ascent, its top plate needs to be inserted into the standard section's steps, and then bolts are tightened to ensure tight contact between the top block of the internal climbing frame and the main body of the standard section, thereby maintaining the stability of the entire tower body. However, existing fixed tower support devices on the market still have the following problems:

[0003] During the climbing process, due to the limited step spacing of the standard section, the height of each ascent is fixed. It cannot be guaranteed that the top block and the horizontal web members of the standard section will remain on the same horizontal plane after the climbing is completed. Therefore, the structure has poor stability and poses certain safety hazards. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the aforementioned background technology and provide an adjustable tower support device for an internal climbing tower crane, which can achieve a small range of height adjustment, so that the horizontal position of the top block and the horizontal web of the tower body is kept as consistent as possible, and the tower crane can achieve a more stable and safe state during operation.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable tower support device for an internal climbing tower crane, comprising an internal climbing frame, support beams, a top plate, pins A, B, and C, and cotter pins matching the pins. The internal climbing frame has two support beams arranged on each of the front and rear sides corresponding to the tower body. The support beams are connected to the inner climbing frame ear plates via pins A, and can rotate around pins A after connection. The top plate has a rotating hole at its head, and is connected to the support beams via pins B, allowing the top plate to rotate around pins B after connection. The top plate has a slot at its tail. When the top plate needs to be used to support the tower steps, pins C are inserted into the support beams, corresponding to the slots at the tail of the top plate, restricting the rotation of the top plate, thereby locking the top plate within the standard section steps.

[0006] In the above technical solution, the support beam is provided with 9 holes. Hole 1 is connected to the inner climbing frame ear plate through pin A, and holes 2 to 9 are evenly distributed to adjust the position of the top plate.

[0007] In the above technical solution, the inner climbing frame is provided with connecting ear plates for connecting the support beam; the bottom of the inner climbing frame is provided with a top block for tightening the tower body.

[0008] The advantages of this adjustable tower support device are as follows:

[0009] 1. Two support beams and a top plate are arranged on each of the front and rear sides of the tower to support the tower body. Compared with the existing single-sided two-point support, the structure is more stable, does not sway, and is safer.

[0010] 2. The pin holes of the top plate can be connected to the rotating holes six to nine of the support beam through pin B, thereby adjusting the height position of the top plate. When the lifting is completed and the top plate is engaged with the standard section step, it can achieve four different height adjustments within a small range, so that the horizontal position of the top block and the horizontal web members of the tower body is kept as consistent as possible. This changes the original rigid fixed stroke and is no longer limited by the step spacing, allowing the tower crane to achieve a more stable and safe state during operation.

[0018] To make the above-mentioned objectives, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0019] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0021] like Figures 1-5 As shown, this embodiment provides an adjustable tower support device for an internal climbing tower crane, including a fixed internal climbing frame 2, a support beam 4, a top plate 3, pins A, B, and C, and cotter pins matching the pins. The lower part of the internal climbing frame 2 is directly connected to the building, and two connecting lugs are welded to each of the two main beams, with the holes of the two connecting lugs aligned. Top blocks 8 are arranged at the four corners of the bottom of the internal climbing frame 2 to tighten the tower body.

[0022] like Figure 2 As shown, the support beam 4 has nine equally spaced holes on each side for connecting pins to adjust its height. The size of the holes is consistent with the size of the connecting lugs on the inner climbing frame 2, and the centers of the holes on both sides of the support beam 4 are aligned. The support beam 4 is connected to the inner climbing frame lugs via pin A, and can rotate around pin A after connection. The number and spacing of the holes in the support beam 4 can be flexibly adjusted according to actual usage requirements to achieve fine-tuning of the tower height.

[0023] like Figure 3 As shown, the top plate 3 has a rotating hole at its head, which is connected to holes six to nine of the support beam 4 via pin B. After connection, the top plate 3 can rotate around pin B. The top plate 3 has a slot at its tail. When the top plate 3 needs to be used to hold the tower steps, pin C is installed in holes two to five, corresponding to the slot at the tail of the top plate, which can restrict the rotation of the top plate 3, thereby locking the top plate 3 into the standard section steps.

[0024] Working Principle: During the operation of the internal climbing tower crane, it is desirable to maintain a small height difference between the standard section's horizontal web members and the bottom top block of the internal climbing frame. Since the step spacing is fixed, the height of the top plate 3 is actively adjusted to match the step landing points at different heights. The holes on both sides of the support beam 4 maintain a 250mm spacing, and the four holes at the top are all adjustable positions for the top plate. Therefore, this embodiment can achieve four levels of height adjustment for the top plate within a 1m range, allowing the tower body to reach the desired position. After the lifting stroke is completed, the positions of the horizontal web members and steps can be observed, and a suitable hole can be selected to connect the pin B.

[0025] In the above embodiment, the connecting ear plate holes of the support beam 4 and the inner climbing frame 2 are aligned in pairs to ensure stable assembly.

[0026] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0027] Those skilled in the art will readily understand that the above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
