Technical Field
[0001] This utility model relates to the field of tower crane support technology, and in particular to an active earthquake response support structure suitable for tower cranes. Background Technology
[0002] Tower cranes are indispensable vertical transportation equipment in construction. Characterized by their towering towers and rotating booms, they efficiently lift and transport materials in three-dimensional space. With rapid urbanization, the safety performance of tower cranes, as key equipment in the construction of high-rise buildings and large structures, has become a major concern. Current technologies largely focus on the seismic design of the building itself; however, the seismic performance of large tower cranes used during construction is often not adequately considered, especially during earthquakes, leading to structural instability and collapse, resulting in numerous casualties and property damage.
[0003] In current technologies, tower crane seismic resistance measures mainly rely on rigid structural design and foundation reinforcement. However, in the face of strong earthquakes, rigid connections may lead to stress concentration in the tower body, resulting in destructive consequences. When encountering strong earthquakes, due to the lack of buffering and energy dissipation mechanisms, tower cranes are prone to tilting, twisting, or even collapse, seriously threatening the lives and property of personnel and property on construction sites. Large cross-section components excessively occupy building space, especially in high-rise building construction, which may affect material transportation and operational efficiency. After rigid structures are damaged in earthquakes, load-bearing components need to be replaced or reinforced as a whole, resulting in long repair cycles and high costs. Rigid designs improve seismic performance by increasing material usage and structural complexity, but in the long run, their life-cycle cost may be higher than that of flexible designs or energy-dissipating and vibration-damping structures, increasing construction costs. Therefore, it is necessary to develop an earthquake-active response support structure suitable for tower cranes to solve the above problems. Utility Model Content
[0004] In order to overcome the problem that the seismic support structure of tower cranes relies on rigid structural design and foundation reinforcement, which seriously threatens the life and property safety of personnel and property on the construction site, may affect material transportation and operation efficiency, and increase construction costs.
[0005] The technical solution of this utility model is as follows: an active earthquake response support structure suitable for tower cranes, including a wall, a connecting mounting shell fixedly connected to the wall, an adjustment component disposed inside the connecting mounting shell, a tower crane connecting seat and a seismic wave detection and processing module disposed on the adjustment component, a first multi-angle adjustment seat connected between the adjustment component and the tower crane connecting seat and the seismic wave detection and processing module, a first hydraulic brake with an oil pump rotatably connected inside the first multi-angle adjustment seat, a second multi-angle adjustment seat connected between the tower crane connecting seat and the seismic wave detection and processing module, a second hydraulic brake rotatably connected to the second multi-angle adjustment seat, and the first hydraulic brake being rotated inside the first multi-angle adjustment seat by means of the first multi-angle adjustment seat.
[0006] Preferably, there are eight second multi-angle adjustment seats, and the eight second multi-angle adjustment seats are symmetrically fixedly connected between the tower crane connecting seat and the seismic wave detection and processing module.
[0007] Preferably, four second hydraulic brakes are provided, and the four second hydraulic brakes are symmetrically rotatably connected inside the second multi-angle adjustment seat.
[0008] Preferably, a seismic wave monitoring column is fixedly connected between the seismic wave detection and processing module and the tower crane connecting seat. A detection probe is installed on the seismic wave monitoring column. A connecting fixing seat is fixedly connected to one side of the tower crane connecting seat and the seismic wave detection and processing module. A tower crane connection structure with an oil pump is installed on the tower crane connecting seat and the seismic wave detection and processing module.
[0009] Preferably, two connecting fixing seats are provided, and the two connecting fixing seats are respectively fixedly connected to the tower crane connecting seat and the seismic wave detection and processing module.
[0010] Preferably, the adjustment assembly includes an air pump fixedly connected to the bottom of the connecting mounting housing, a fixing bolt disposed between the connecting mounting housing and the wall, a fixing rod fixedly connected inside the connecting mounting housing, a sliding limit block slidably connected to the fixing rod, a sliding connecting block fixedly connected to the inner side of the sliding limit block, and a pneumatic telescopic rod disposed between the air pump and the sliding connecting block.
[0011] Preferably, there are two fixing rods, and the two fixing rods are symmetrically fixedly connected to the connecting mounting shell.
[0012] Preferably, the connecting mounting shell has a groove at the corresponding position of the sliding limit block, and the sliding limit block slides inside the groove.
[0013] The beneficial effects of this utility model are:
[0014] 1. Compared to the seismic support structure of tower cranes that relies on rigid structural design and foundation reinforcement, the cooperation between the first hydraulic brake and the first multi-angle adjustment seat, and the cooperation between the second multi-angle adjustment seat and the second hydraulic brake between the tower crane connecting seat and the seismic wave detection and processing module, reduces the occurrence of destructive consequences, prevents the lack of buffering and energy dissipation mechanisms that could easily lead to tilting, twisting, or even collapse, ensures the safety of life and property of personnel and property at the construction site, ensures material transportation and operational efficiency, reduces the length of the repair cycle, lowers repair costs, and reduces the cost of equipment construction.
[0015] 2. First, install the connecting housing to the approximate position on the wall. Then, use the air pump to drive the pneumatic telescopic rod to slide inside the connecting housing, moving the device to the appropriate position to ensure the stability of the connection. The wall-mounted tower crane needs to be frequently repositioned according to the construction progress. The adjustable support structure can change the anchor points in real time as the tower crane moves, ensuring a stable connection with the main building structure at all times. For example, in the construction of super high-rise buildings, the tower crane needs to climb along the core tube wall. The adjustable support can quickly adapt to changes in the wall angle at different heights through telescopic legs or rotating connectors, avoiding tower crane tilting due to support misalignment.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0023] Please see Figure 1 - Figure 5 This utility model provides an embodiment of an active seismic response support structure for tower cranes, including a wall 1, a connecting mounting shell 2 fixedly connected to the wall 1, an adjustment component disposed inside the connecting mounting shell 2, a tower crane connecting seat 3 and a seismic wave detection and processing module 4 disposed on the adjustment component, a first multi-angle adjustment seat 902 connected between the adjustment component and the tower crane connecting seat 3 and the seismic wave detection and processing module 4, a first hydraulic brake 901 with an oil pump rotatably connected inside the first multi-angle adjustment seat 902, a second multi-angle adjustment seat 904 connected between the tower crane connecting seat 3 and the seismic wave detection and processing module 4, and a second hydraulic brake 905 rotatably connected to the second multi-angle adjustment seat 904. The first hydraulic brake 901 rotates inside the first multi-angle adjustment seat 902 by the first multi-angle adjustment seat 902. When irregular disturbances are detected on the ground or the tower crane structure, the system immediately executes rapid... Fourier transform is used to perform time-frequency domain analysis on the signal to determine if it is a P-wave signal. If the P-wave is successfully identified, the system performs an initial magnitude estimate and determines whether to enter response mode. The central control module issues control commands to transmit hydraulic pressure to the first hydraulic brake 901 and the second hydraulic brake 905. The release ratio is selected according to the magnitude and direction, and the sliding structure is allowed to slide along the guide rail direction with buffer. The hydraulic actuators release slowly within the set time window, and a small displacement occurs in the middle section of the structure. At the same time, the built-in damping element dissipates energy. With the cooperation of the first hydraulic brake 901 and the first multi-angle adjustment seat 902 and the second multi-angle adjustment seat 904 and the second hydraulic brake 905, the structure is prevented from shaking violently. If the arrival of the main shock S-wave is detected during the release stage, or the magnitude exceeds the safety setting value, the system immediately increases the hydraulic pressure to the locking value. The first hydraulic brake 901 and the second hydraulic brake 905 are set to complete the structural locking in a very short time.
[0024] Please see Figure 4 - Figure 5In this embodiment, eight second multi-angle adjustment seats 904 are provided, and the eight second multi-angle adjustment seats 904 are symmetrically and fixedly connected between the tower crane connecting seat 3 and the seismic wave detection and processing module 4. The eight second multi-angle adjustment seats 904 provide a stable buffering effect for the tower crane connecting seat 3 and the seismic wave detection and processing module 4. Four second hydraulic brakes 905 are provided, and the four second hydraulic brakes 905 are symmetrically and rotatably connected inside the second multi-angle adjustment seats 904. The four second hydraulic brakes 905 ensure the stability of the buffering. A seismic wave monitoring column 906 is fixedly connected between the seismic wave detection and processing module 4 and the tower crane connecting seat 3. The seismic wave monitoring column 906 is equipped with... A detection probe 907 is provided. A connecting fixing seat 908 is fixedly connected to one side of the tower crane connecting seat 3 and the seismic wave detection and processing module 4. A tower crane connecting structure 903 with an oil pump is provided on the tower crane connecting seat 3 and the seismic wave detection and processing module 4. The detection probe 907 on the set seismic wave monitoring column 906 senses the external seismic signal. The tower crane connecting structure 903 with an oil pump provides energy for the adjustment of the first hydraulic brake 901 and the tower crane connecting structure 903 with an oil pump. There are two connecting fixing seats 908, and the two connecting fixing seats 908 are fixedly connected to the tower crane connecting seat 3 and the seismic wave detection and processing module 4 respectively. The two connecting fixing seats 908 make the fixation more stable.
[0025] Please see Figure 2 - Figure 3 In this embodiment, the adjustment assembly includes an air pump 801 fixedly connected to the bottom of the connecting mounting housing 2, a fixing bolt 802 disposed between the connecting mounting housing 2 and the wall 1, a fixing rod 804 fixedly connected inside the connecting mounting housing 2, a sliding limit block 803 slidably connected to the fixing rod 804, a sliding connecting block 805 fixedly connected to the inner side of the sliding limit block 803, and a pneumatic telescopic rod 806 disposed between the air pump 801 and the sliding connecting block 805. The air pump 801 drives the pneumatic telescopic rod 806 to push the sliding connecting block 805 to slide inside the connecting mounting housing 2, and the sliding connecting block 805 slides through the sliding limit block 805. The movable limiting block 803 slides under the limitation of the fixed rod 804, ensuring the stability of the sliding connecting block 805. There are two fixed rods 804, which are symmetrically fixed to the connecting mounting shell 2. The two fixed rods 804 make the sliding connecting block 805 more stable when sliding inside the connecting mounting shell 2. The connecting mounting shell 2 has a groove at the corresponding position of the sliding limiting block 803. The sliding limiting block 803 slides inside the groove. The groove at the corresponding position of the sliding limiting block 803 inside the connecting mounting shell 2 limits the sliding limiting block 803 when it slides inside the connecting mounting shell 2.
[0026] During operation, the detection probe 907 on the seismic wave monitoring column 906 senses external seismic signals. The tower crane connection structure 903 with its oil pump provides energy for the adjustment of the first hydraulic brake 901 and the tower crane connection structure 903. If irregular disturbances are detected on the ground or tower crane structure, the system immediately performs a fast Fourier transform to analyze the signal in the time and frequency domains to determine if it is a P-wave signal. If the P-wave is successfully identified, the system performs a preliminary magnitude estimate and determines whether to enter response mode. The central control module issues control commands, transmitting hydraulic pressure to the first hydraulic brake 901 and the second hydraulic brake 905. The release ratio is selected based on the magnitude and direction, and the sliding structure is allowed to slide buffered along the guide rail. The hydraulic actuators respond within a set time... The system slowly releases from the window, causing a small displacement in the middle section of the structure. Simultaneously, the built-in damping element dissipates energy. With the cooperation of the first hydraulic brake 901, the first multi-angle adjustment seat 902, the second multi-angle adjustment seat 904, and the second hydraulic brake 905, the structure is prevented from shaking violently. If the main shock S-wave is detected during the release phase, or if the magnitude exceeds the safety setting value, the system immediately increases the hydraulic pressure to the locking value. The first hydraulic brake 901 and the second hydraulic brake 905 complete the structural locking in a very short time. When adjusting the installation of the device, the air pump 801 drives the pneumatic telescopic rod 806 to push the sliding connecting block 805 to slide inside the connecting and mounting shell 2. The sliding limit block 803 on the sliding connecting block 805 slides under the limit of the fixed rod 804.
[0027] Through the above steps, the cooperation between the first hydraulic brake 901 and the first multi-angle adjustment seat 902, and the cooperation between the second multi-angle adjustment seat 904 and the second hydraulic brake 905 between the tower crane connecting seat 3 and the seismic wave detection and processing module 4, enables the initial seismic signal to be received and a flexible buffer response to be made. It can be quickly locked before the main shock arrives, so as to solve the problem that the seismic support structure of the tower crane relies on rigid structural design and foundation reinforcement, which seriously threatens the life and property safety of personnel at the construction site, may affect material transportation and operation efficiency, and increase construction costs.
