Description

Technical Field

[0001] This utility model relates to the field of tower crane technology, specifically to a protective tower crane attachment frame. Background Technology

[0002] A tower crane attachment frame is a device designed to ensure the stability of a tower crane when it reaches a certain height. One end of it is attached to the tower crane body via an attachment frame, and the other end is fixed to the wall or structure of a building via a connecting joint.

[0003] Referring to Chinese Patent Publication No. CN220376206U, published on January 23, 2024, a tower crane attachment frame is disclosed, including a first attachment frame and a second attachment frame. Both the first and second attachment frames are equipped with a connecting mechanism. Each attachment frame has a support rod on its front side, and a positioning component is connected to the support rod. The connecting mechanism includes two first connecting plates, both fixedly connected to one side of the first attachment frame. Through the design of the connecting mechanism, the first and second attachment frames are spliced ​​together using the first and second connecting plates during installation. Furthermore, after the insert block is inserted into the insertion hole, it provides support at the connection point, ensuring the stability of the connection and effectively guaranteeing the strength of the first and second attachment frames after splicing outside the tower crane. This avoids the limitations of reinforcement methods such as motor-driven systems.

[0004] The existing attachment frame mentioned above lacks effective safety protection measures such as anti-tilting and anti-slip during the tower crane attachment process. It is easy for the tower crane to become unstable due to external forces. The attachment frame is prone to damage after long-term use and needs to be replaced. The non-removable connection method means that the entire attachment frame needs to be replaced, which increases maintenance costs. In addition, the non-removable nature makes the attachment frame inconvenient to transport and stack on site.

[0005] The existing technology has the following technical problems: the protective effect of the existing tower crane attachment frame needs to be improved, and a single attachment frame is not easy to disassemble; therefore, we propose a protective tower crane attachment frame to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a protective tower crane attachment frame to solve the problems mentioned in the background art, such as the need to improve the protective effect of existing tower crane attachment frames and the inconvenience of disassembling individual attachment frames.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a protective tower crane attachment frame, comprising a rear attachment frame, side attachment frames, a front attachment frame, and a connecting plate. Two side attachment frames are installed within the rear and front attachment frames via an installation structure and screws. A connecting structure is installed on the outer side of each side attachment frame, and a stabilizing structure is provided within the connecting structure. An adjustment structure is installed on the front side of the front attachment frame, and a connecting rod is connected to the front side of the adjustment structure. A connecting plate is fixedly connected to the front side of the connecting rod.

[0008] The stabilizing structure includes a stabilizing screw and stabilizing nuts. Two stabilizing nuts are threaded to the outside of the stabilizing screw. The connecting structure includes a first connecting block and a second connecting block. The first connecting block is fixedly installed on the top of the rear attachment frame and the front attachment frame and the bottom of the two side attachment frames, respectively. The second connecting block is fixedly installed on the outside of the two side attachment frames.

[0009] Preferably, the mounting structure includes a mounting groove and a mounting block, wherein the mounting groove is provided with the mounting block.

[0011] Preferably, the mounting slots are longitudinally formed at both ends of the rear attachment frame.

[0012] Preferably, the mounting block is fixedly mounted on the front and rear ends of the side attachment frame.

[0013] Preferably, both the first connecting block and the second connecting block are provided with stabilizing screws.

[0014] Preferably, the adjustment structure includes an adjustment frame, adjustment holes, adjustment blocks, and limiting screws. The adjustment frame has equidistant adjustment holes in its top and bottom walls. An adjustment block is slidably connected inside the adjustment frame, and the adjustment block is limited within the adjustment frame by the limiting screws.

[0015] Preferably, the adjustment frame is fixedly installed on the left and right ends of the front attachment frame.

[0016] Preferably, a connecting rod is fixedly connected to the front side of the adjusting block.

[0017] Compared with the prior art, the beneficial effects of this utility model are: the protective tower crane attachment frame improves the overall protection and safety of the attachment frame through the connection structure and the stabilizing structure; the installation structure makes the attachment frame easy to disassemble, thereby reducing maintenance costs; it also facilitates the transportation and on-site stacking of the attachment frame; and the adjustment structure makes it easy to adjust the position of the two connecting plates, further improving stability.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-6 The present invention provides the following technical solution:

[0033] Example 1: A protective tower crane attachment frame includes a rear attachment frame 1, a side attachment frame 2, a front attachment frame 3, and a connecting plate 9. Two side attachment frames 2 are installed inside the rear attachment frame 1 and the front attachment frame 3 by means of an installation structure 4 and screws. A connecting structure 6 is installed on the outside of the side attachment frames 2. A stabilizing structure 5 is provided inside the connecting structure 6. An adjustment structure 7 is installed on the front side of the front attachment frame 3. A connecting rod 8 is connected to the front side of the adjustment structure 7. A connecting plate 9 is fixedly connected to the front side of the connecting rod 8.

[0034] like Figures 1-4 and Figure 6 As shown, the connecting structure 6 includes a first connecting block 601 and a second connecting block 602, and the stabilizing structure 5 includes a stabilizing screw 501 and a stabilizing nut 502. The top of the rear attachment frame 1 and the front attachment frame 3 are both fixedly installed with the first connecting block 601. The two first connecting blocks 601 have through holes on their opposite sides. A stabilizing screw 501 is passed from the rear first connecting block 601 to the front first connecting block 601, and stabilizing nuts 502 are screwed on both ends. Tightening the stabilizing nuts 502 makes the stabilizing nuts 502 fit tightly against the first connecting block 601, thereby fixing the stabilizing screw 501, which improves the connection stability between the rear attachment frame 1 and the front attachment frame 3.

[0035] A first connecting block 601 is fixedly installed at the bottom of both the left and right side attachment frames 2. The two first connecting blocks 601 also have through holes on their opposite sides. A stabilizing screw 501 is passed from the left first connecting block 601 to the right first connecting block 601. Stabilizing nuts 502 are screwed on both ends. Tightening the stabilizing nuts 502 will make the stabilizing nuts 502 fit tightly against the first connecting block 601, thereby fixing the stabilizing screw 501 and improving the connection stability of the left and right side attachment frames 2.

[0036] Two second connecting blocks 602 are fixedly installed on the outer side of the side attachment frame 2 at both ends. The second connecting block 602 has through holes on the top and bottom. A stabilizing screw 501 is passed from the lower second connecting block 602 to the corresponding upper second connecting block 602. Stabilizing nuts 502 are screwed on both the top and bottom ends. Tightening the stabilizing nuts 502 will make the stabilizing nuts 502 fit tightly against the second connecting block 602, thereby fixing the stabilizing screw 501 and improving the stability of the upper and lower attachment frames.

[0037] By connecting the front, back, left, right, top, and bottom with stabilizing screws 501, a spatial truss structure is formed, which can effectively resist horizontal forces from different directions such as wind load, seismic force, and hoisting eccentric load, thereby improving the overall stability of the attachment frame. At the same time, the multi-point fixing forms a closed protective structure, which effectively prevents the tower crane from tilting or slipping during the attachment process, thereby improving the overall protection and safety of the attachment frame.

[0038] like Figures 1-4 As shown, the mounting structure 4 includes a mounting groove 401 and a mounting block 402. The rear attachment frame 1 and both the left and right ends are provided with longitudinal mounting grooves 401. The front and rear ends of the side attachment frames 2 at both ends are fixedly connected with mounting blocks 402. The mounting block 402 on the rear side of the side attachment frame 2 is inserted into the mounting groove 401 of the rear attachment frame 1 and screwed in from both sides to fix the mounting block 402, thereby fixing the rear attachment frame 1 and the side attachment frame 2. After the side attachment frames 2 at both ends are installed, the mounting block 402 on the front side of the side attachment frame 2 is inserted into the mounting groove 401 of the front attachment frame 3 and fixed with screws, thereby fixing the side attachment frame 2 and the front attachment frame 3 to form a complete attachment frame.

[0039] Using this structure for installation and fixing with screws, the rear attachment frame 1, side attachment frame 2, and front attachment frame 3 can all be easily disassembled. Simply remove the screws and pull the mounting blocks 402 at the front and rear ends out of the mounting slots 401 to disassemble. This easy-to-disassemble design allows for direct replacement of a damaged individual frame without the need for complete replacement, thus reducing maintenance costs. The detachable design also facilitates the transportation and on-site stacking of the attachment frames.

[0040] Example 2: The adjustment structure 7 includes an adjustment frame 701, adjustment holes 702, adjustment blocks 703, and limiting screws 704. The adjustment frame 701 is fixedly installed on the left and right ends of the front attachment frame 3. The top and bottom walls of the adjustment frame 701 are provided with equidistant adjustment holes 702. The adjustment block 703 is slidably connected inside the adjustment frame 701. The adjustment block 703 is moved left and right. A connecting rod 8 is fixedly connected to the front side of the adjustment block 703. The adjustment block 703 drives the connecting rod 8 to move left and right. A connecting plate 9 is fixedly connected to the front side of the connecting rod 8. The connecting rod 8 drives the connecting plate 9 to move left and right, thereby adjusting the position of the connecting plate 9 and making fine adjustments to the connecting plate 9 to further improve stability.

[0041] Next, select a suitable position. The adjusting block 703 has through holes on the top and bottom surfaces. Align the through hole with the adjusting hole 702. Use the limiting screw 704 to screw into the adjusting frame 701 from the top, pass through the adjusting block 703 and screw into the bottom of the adjusting frame 701, thereby fixing the adjusting block 703 and thus fixing the connecting plate 9.

[0042] Installation method: First, rotate the rear attachment frame 1, side attachment frame 2, and front attachment frame 3 to the appropriate length according to the tower crane size. Use the installation structure 4 and screws to fix and connect the parts at each position of the attachment frame. Then, install and fix the stabilizing screw 501 to protect and reinforce the tower crane attachment frame. Adjust and fix the position of the connecting plates 9 at both ends of the structure as needed. Finally, fix the connecting plates 9 to the connecting structure.

[0043] The above completes a series of operations for the protective tower crane attachment frame. Any content not described in detail in this instruction belongs to the prior art known to those skilled in the art.
