[0035] like Figure 1-Figure 5As shown, this embodiment provides a shock absorbing device, which includes a supporting frame 1, a first connecting member 2, a pressing member 3, a first elastic member 4 and a second elastic member 5. The supporting frame 1 is detachably connected to the climbing formwork structure 100, the first connecting member 2 is detachably connected to the supporting frame 1, and is provided with a connecting groove 21 for accommodating the supporting leg 200 of the material placing machine, the pressing member 3 is connected to the first connecting member 2, and abuts against the notch end of the connecting groove 21, the first elastic member 4 is arranged on the pressing member 3, and the pressing member 3 can clamp the supporting leg 200 of the material placing machine between the pressing member 3 and the first connecting member 2 under the elastic action of the first elastic member 4, and the second elastic member 5 is clamped between the supporting leg 200 of the material placing machine and the groove bottom of the connecting groove 21.

[0036] In this embodiment, the support frame 1 can be detachably connected to the climbing formwork structure 100, and the first connecting member 2 can be detachably connected to the support frame 1, so as to facilitate the disassembly and assembly of various components and facilitate the installation and maintenance by construction personnel. The first connecting member 2 is provided with a connecting groove 21 for accommodating the supporting leg 200 of the concrete placing machine, so that the supporting leg 200 of the concrete placing machine can be inserted into the connecting groove 21 for connection. The pressing member 3 is connected to the first connecting member 2 and abuts against the notch end of the connecting groove 21 to ensure that the supporting leg 200 of the concrete placing machine will not move out of the connecting groove 21, thereby improving the stability and safety of the operation. The first elastic member 4 is provided on the pressing member 3. Under the elastic action of the first elastic member 4, the pressing member 3 can clamp the supporting leg 200 of the concrete placing machine between the pressing member 3 and the first connecting member 2, which not only ensures the stability of the concrete placing machine during operation, but also provides appropriate buffering through the elastic action of the first elastic member 4, thereby reducing the vibration of the concrete placing machine during operation. The second elastic member 5 is sandwiched between the supporting leg 200 of the concrete placing machine and the bottom of the connecting groove 21. The first elastic member 4 and the second elastic member 5 cooperate with each other to achieve a double shock-absorbing effect, reduce the impact of the concrete placing machine vibration on the climbing formwork structure 100 and the lower structure, reduce safety risks, and further ensure construction safety. Through the above arrangement, the shock-absorbing device of this embodiment can reduce the vibration of the concrete placing machine during operation and improve the stability and safety of the operation.

[0037] Specifically, Figure 1-Figure 3 As shown, a limiting member 101 is provided on the climbing formwork structure 100, and the limiting member 101 can abut against the supporting frame 1 and can be detachably connected to the supporting frame 1, which can ensure that when the fabric spreading machine is working, the supporting frame 1 will not produce excessive displacement on the climbing formwork structure 100, which not only enhances the stability of the overall structure and improves the installation accuracy, but also facilitates the disassembly and replacement of various components, reducing safety risks. Among them, the limiting member 101 can adopt a limiting block or a protrusion to achieve the above function, that is, the specific structure of the limiting member 101 is not limited. The above-mentioned detachable connection can be screwed, clamped, etc., which is not further limited here.

[0038] Specifically, Figure 1-Figure 3As shown, the shock absorbing device further includes a second connecting member 6, one end of which is detachably connected to the climbing formwork structure 100 for easy disassembly and assembly. The other end of the second connecting member 6 forms a limiting groove 61 with the climbing formwork structure 100, and the supporting frame 1 can abut against the inner wall of the limiting groove 61, thereby limiting the movement of the supporting frame 1 in the horizontal and vertical directions, reducing the displacement of the supporting frame 1 caused by vibration or external force, thereby further enhancing the stability and safety of the entire structure.

[0039] More specifically, if Figure 3 As shown, in this embodiment, the second connecting member 6 includes a connecting plate, one end of which is screwed to the climbing formwork structure 100 by bolts, so as to facilitate the disassembly and assembly of various components and subsequent maintenance. In other embodiments, the second connecting member 6 includes a U-shaped steel, which is connected to the climbing formwork structure 100 and has a limiting groove 61 formed inside to achieve the limiting of the supporting frame 1. That is, the specific structure of the second connecting member 6 is not limited, as long as it can achieve the above-mentioned functions.

[0040] Specifically, Figure 1 and Figure 2 As shown, the shock absorbing device also includes a diagonal brace 7, and the two ends of the diagonal brace 7 are detachably connected to the support frame 1 and the climbing formwork structure 100, respectively. The diagonal brace 7 forms a stable triangular support structure between the support frame 1 and the climbing formwork structure 100 to enhance the structural stability of the entire device. Through the above arrangement, the support frame 1 can be effectively prevented from shaking or displacement due to vibration or other external forces when the concrete placing machine is working, thereby ensuring the safety and stability of the construction. Moreover, the two ends of the diagonal brace 7 can be detachably connected by screw connection, clamping connection or other detachable connection methods, making the installation process more flexible and convenient. Construction personnel can quickly complete the installation and adjustment of the diagonal brace 7 according to actual needs and site conditions, thereby improving work efficiency.

[0041] More specifically, a plurality of diagonal bracing members 7 are provided, and every two diagonal bracing members 7 are cross-arranged as a group. The cross-arrangement of the diagonal bracing members 7 provides additional support for the bearing frame 1 in the horizontal direction, thereby enhancing the anti-lateral displacement capability of the overall structure. Each group of diagonal bracing members 7 is parallel to each other and arranged at intervals in the horizontal direction, which can further improve the stability of the structure, thereby reducing the safety risks caused by structural instability and protecting the safety of construction personnel and equipment.

[0042] Specifically, Figure 1 As shown, there are multiple first connecting members 2, which are respectively arranged at the four corners of the supporting frame 1 and correspond one-to-one with the supporting legs 200 of the concrete placing machine, which can ensure that the supporting force of the concrete placing machine is evenly distributed to the four corners of the supporting frame 1, thereby avoiding local overload and improving the bearing capacity and stability of the supporting frame 1.

[0043] More specifically, if Figure 1-Figure 4As shown, in this embodiment, the first connecting member 2 includes a T-shaped plate, and a connecting groove 21 is provided on the T-shaped plate. By providing the T-shaped plate, it is ensured that the first connecting member 2 and the bearing frame 1 are conformally matched and firmly connected. The T-shaped plate is provided with a plurality of connecting holes in the circumference, and bolts are passed through the connecting holes and the bearing frame 1, so that the T-shaped plate is detachably connected to the bearing frame 1. In other embodiments, the first connecting member 2 includes a flat plate, and the flat plate is screwed to the bearing frame 1. That is, the specific structure of the first connecting member 2 is not limited, as long as the above-mentioned functions can be achieved.

[0044] Specifically, Figure 1-Figure 5 As shown, the covering member 3 includes a plurality of covering plates 31, which can be arranged around the circumference of the fabric crane leg 200 and can be detachably connected to the first connecting member 2. By configuring the covering member 3 as a plurality of independent covering plates 31, it is convenient for the operator to sleeve the covering member 3 on the fabric crane leg 200. Moreover, such a configuration makes the fabric crane leg 200 more stable during operation, reducing the displacement caused by vibration or external force. In addition, since the covering plate 31 is detachably connected to the first connecting member 2, the construction personnel can adjust it according to the actual size of the fabric crane leg 200, so that the shock absorbing device can adapt to fabric crane legs 200 of different specifications and types, thereby improving its versatility and adaptability. It should be noted that the above-mentioned detachable connection can be achieved by screw connection, clamping connection, etc., which is not limited here.

[0045] More specifically, if Figure 1-Figure 5 As shown, the pressing member 3 also includes a fastener 32, and the pressing plate 31 is connected to the first connecting member 2 through the fastener 32. By setting the fastener 32, the pressing plate 31 is fixed on the first connecting member 2, ensuring that the pressing plate 31 can be stably arranged around the supporting leg 200 of the concrete placing machine. The two ends of the first elastic member 4 are respectively in contact with the pressing plate 31 and the fastener 32, playing a role of buffering and shock absorption. When the concrete placing machine is running, the pressing plate 31 may be subjected to certain impacts and vibrations due to vibration or other forces. The first elastic member 4 can effectively absorb these impacts and vibrations, protect the pressing plate 31 and the first connecting member 2 from damage, and reduce the impact of the concrete placing machine vibration on the climbing formwork structure 100 and the lower structure, reduce safety risks, and further ensure construction safety. Among them, the fastener 32 can be a bolt or a screw structure, which is not limited here. The first elastic member 4 can be a coil spring or a plate spring, and the specific structure of the first elastic member 4 is not limited here, as long as it can achieve the above-mentioned functions.

[0046] Specifically, Figure 1-Figure 5As shown, the bottom of the connecting groove 21 is conformally matched with the fabric spreading machine leg 200 to ensure that the fabric spreading machine leg 200 can be firmly placed in the connecting groove 21. Moreover, the diameter of the bottom of the connecting groove 21 is larger than the diameter of the fabric spreading machine leg 200, ensuring that the fabric spreading machine leg 200 will not generate excessive friction or get stuck with the groove wall of the connecting groove 21, thereby facilitating installation and disassembly.

[0047] Specifically, Figure 1 As shown, the load-bearing frame 1 includes two cross bars 11 and two vertical bars 12. The two ends of the vertical bars 12 are respectively connected to the two cross bars 11. The two cross bars 11 and the two vertical bars 12 are crisscrossed to form a frame structure. Such an arrangement enables the load-bearing frame 1 to evenly distribute the load, thereby improving its load-bearing capacity.

[0048] More specifically, if Figure 1 As shown, in this embodiment, the frame structure is generally an H-shaped structure to facilitate the layout and installation of various components. In other embodiments, the frame structure can be a well-shaped structure, which is not limited here.
