Description

Technical Field

[0001] The invention relates to the technical field of bridge construction, and in particular to an adaptive tower crane foundation and a use method thereof. Background Art

[0002] During the construction process, tower cranes are able to perform various complex lifting operations at high altitudes with their tall towers and flexible lifting arms. They are widely used in the field of bridge construction, especially in the construction of cable-stayed bridge towers.

[0003] When the cable tower is being constructed, the tower crane foundation of some projects is set on the ground, and the tower crane extends upward from the ground to the top of the steel box girder (the main beam of the cable-stayed bridge), and the distance between the tower crane and the cable tower is small, and the tower crane's lifting arm is short. Although this setting can enable the tower crane to lift a larger weight, the tower crane will occupy the construction space of the steel box girder, so that the construction of the steel box girder and the cable tower will conflict. The construction of the steel box girder and the cable tower can only be carried out step by step, which increases the construction period of the cable-stayed bridge. In order to allow the construction of the steel box girder and the cable tower to be carried out simultaneously, the existing technology sets the tower crane foundation on the side of the steel box girder away from the cable tower to avoid the construction space of the steel box girder, but this setting will increase the length of the tower crane's lifting arm, which not only increases the cost of the tower crane, but also reduces the stability of the lifting arm, so that the tower crane will face greater safety risks during use, and the weight that the tower crane can lift is limited.

[0004] In order to solve the above problems, some existing projects anchor the tower crane foundation to the cable tower and set it above the steel box girder. When the cable tower is constructed using the tower crane foundation anchored on the cable tower, the cable tower construction can be carried out above the tower crane foundation, and the steel box girder construction can be carried out below the tower crane foundation, realizing the simultaneous construction of the steel box girder and the cable tower. Moreover, this tower crane foundation is also suitable for some working conditions where the tower crane foundation cannot be set on the ground, such as the construction of a cross-sea cable-stayed bridge. However, as the height of the tower crane continues to increase during the cable tower construction process, the load on the tower crane foundation anchored on the cable tower also gradually increases. In order to firmly support the tower crane, the structure of the tower crane foundation is set larger, which not only increases the construction cost, but also makes the number of connection positions between the tower crane foundation and the cable tower larger, increasing the degree of damage to the cable tower. In addition, the existing tower crane foundation anchored to the cable tower is a cantilever structure. As the weight of the tower crane continues to increase, the cantilevered end of the tower crane foundation is prone to vertical movement, causing the tower crane to tilt and even exceed the allowable range of tower crane tilt. Not only can the tower crane continue to be used, but there are also major safety hazards.

[0005] Therefore, there is an urgent need for an adaptive tower crane foundation and a method of using the same to solve the above problems. Summary of the invention

[0020] On the other hand, a method for using an adaptive tower crane foundation is provided, using the adaptive tower crane foundation to support a tower crane, specifically comprising the following steps:

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The present invention provides an adaptive tower crane foundation and a method for using the same. The supporting bracket, the anchor bracket and the elastic inclined brace of the adaptive tower crane foundation can all be anchored to the cable tower and are located above the steel box girder as a whole. The cable tower construction can be carried out above the adaptive tower crane foundation, and the steel box girder construction can be carried out below the adaptive tower crane foundation, that is, the tower crane will not occupy the construction space of the steel box girder, so that the steel box girder construction and the cable tower construction can be carried out simultaneously.

[0028] The elastic diagonal member passes through the second end of the upper load-bearing beam and is connected to the end of the lower load-bearing beam away from the cable tower. During the cable tower construction, when the supporting mechanism drives the cantilevered end of the anchor bracket to move downward relative to the horizontal plane under the action of the tower crane's gravity, the staff can change the length of the elastic diagonal member by pulling the elastic diagonal member, so that elastic force is generated in the elastic diagonal member. The elastic force is converted into an upward pulling force on the anchor bracket at the anchor bracket, thereby pulling up the anchor bracket, and the anchor bracket drives the supporting mechanism to move, thereby realizing the adjustment of the inclination degree of the tower crane during the construction process, so that the safety of the construction process is guaranteed and the cable tower construction can proceed smoothly.

[0029] After the tower crane is installed, the second end of the upper load-bearing beam is driven upward by the jacking drive, and the upper load-bearing beam drives the tower crane through the support bracket to be in an inclined state before the construction begins, which provides a margin for the inclination of the tower crane during the cable tower construction process, thereby reducing the number of times the inclination of the tower crane is adjusted during the subsequent cable tower construction process and improving the construction rate. During the cable tower construction process, when the inclination of the tower crane is too large, the inclination of the tower crane can be further adjusted by driving the second end of the upper load-bearing beam upward by the jacking drive to ensure the smooth progress of the cable tower construction.

[0030] Both the support bracket and the anchor bracket are plane truss structures, which have the characteristics of flexible structural layout, so that the construction site can be reasonably arranged according to specific conditions; the connecting beam assembly not only connects multiple support brackets into a whole, but also connects the anchor bracket and the support bracket into a whole, so that the anchor bracket and the support bracket can be synergistically stressed. Compared with the existing cantilever tower crane foundation, the adaptive tower crane foundation provided by the present invention can apply an upward pulling force to the anchor bracket during the cable tower construction process through an elastic inclined member, and the pulling force can offset part of the load of the tower crane on the support bracket, thereby reducing the load on the anchor bracket and the cantilever end of the support bracket and the whole thereof, so that the anchor bracket and the support bracket can reach the bearing capacity of the existing tower crane foundation with less material, thereby reducing the construction cost.

[0031] Furthermore, the reduction in the weight of the adaptive tower crane foundation can not only reduce the anchor tension of the adaptive tower crane foundation on the cable tower, but also reduce the number of connection positions between the adaptive tower crane foundation and the cable tower, thereby reducing the degree of damage to the cable tower caused by the adaptive tower crane foundation.

[0056] Embodiment 1

[0057] like Figures 1 to 12 As shown, this embodiment provides an adaptive tower crane foundation 100 for supporting the tower crane 300 when the cable tower 200 is under construction, and can realize the construction of the cable tower 200 and the construction of the steel box girder 400 at the same time. While ensuring the bearing capacity, the manufacturing cost of the adaptive tower crane foundation 100 and the impact on the cable tower 200 are reduced. The inclination of the tower crane 300 can also be adjusted at any time during the construction of the cable tower 200, and the safety of the construction process is guaranteed.

[0058] See also Figure 1 , Figure 2 and Figure 3 The adaptive tower crane foundation 100 is installed above the steel box beam 400, and includes a support mechanism 1 and an anchoring mechanism 2. The support mechanism 1 includes a plurality of support brackets 11 and a connecting beam assembly 12. The plurality of support brackets 11 are arranged along a first direction ( Figure 2The plurality of support brackets 11 are arranged at intervals in the X direction, and are connected by a connecting beam assembly 12. The support brackets 11 are planar truss structures and can be anchored to the cable tower 200. The legs 301 of the tower crane 300 are detachably mounted on the support brackets 11; see Figure 2 and Figure 4 The anchoring mechanism 2 includes two anchoring brackets 21, an elastic inclined member 22 and a jacking driving member 23. The two anchoring brackets 21 are arranged on both sides of the supporting mechanism 1 along the first direction and are fixedly connected to the connecting beam assembly 12. The anchoring brackets 21 are plane truss structures and can be anchored to the cable tower 200. The anchoring brackets 21 include two anchoring brackets 21 along the second direction ( Figure 2 The upper load-bearing beam 211 and the lower load-bearing beam 212 extend in the vertical direction ( Figure 4 The jacking drive 23 is arranged at intervals in the Z direction of the tower 300; the jacking drive 23 is arranged on the lower load-bearing beam 212, the output end of the jacking drive 23 is connected to the upper load-bearing beam 211, the first end of the upper load-bearing beam 211 is fixed to the cable tower 200, and the second end of the upper load-bearing beam 211 can move upward under the drive of the jacking drive 23, and move downward under the gravity of the tower crane 300; one end of the elastic inclined brace 22 can be anchored to the cable tower 200 and rotate relative to the cable tower 200, and the other end passes through the second end of the upper load-bearing beam 211 and is anchored to the end of the lower load-bearing beam 212 away from the cable tower 200. When the elastic inclined brace 22 is pulled or the second end of the upper load-bearing beam 211 is driven to move vertically, the length of the elastic inclined brace 22 changes, and the elastic inclined brace 22 applies an upward pulling force to the anchor bracket 21, and the first direction, the second direction and the vertical direction are perpendicular to each other. Among them, the first end and the second end are the two ends of the upper load-bearing beam 211 along the second direction.

[0059] The supporting bracket 11, the anchor bracket 21 and the elastic inclined member 22 of the adaptive tower crane foundation 100 provided in this embodiment can be anchored to the cable tower 200, and are located above the steel box girder 400 as a whole. The construction of the cable tower 200 can be carried out above the adaptive tower crane foundation 100, and the construction of the steel box girder 400 can be carried out below the adaptive tower crane foundation 100, that is, the tower crane 300 will not occupy the construction space of the steel box girder 400, so that the construction of the steel box girder 400 and the cable tower 200 can be carried out simultaneously.

[0060] The elastic diagonal brace 22 passes through the second end of the upper load-bearing beam 211 and is connected to the end of the lower load-bearing beam 212 away from the cable tower 200. During the construction of the cable tower 200, when the support mechanism 1 drives the cantilevered end of the anchor bracket 21 to move downward relative to the horizontal plane under the action of the gravity of the tower crane 300, the staff can change the length of the elastic diagonal brace 22 by pulling the elastic diagonal brace 22, so that an elastic force is generated in the elastic diagonal brace 22. The elastic force is converted into an upward pulling force on the anchor bracket 21 at the anchor bracket 21, thereby pulling up the anchor bracket 21, and the anchor bracket 21 drives the support mechanism 1 to move, so as to adjust the inclination degree of the tower crane 300 during the construction process, so that the safety of the construction process is guaranteed and the construction of the cable tower 200 can proceed smoothly. After the tower crane 300 is installed, the second end of the upper load-bearing beam 211 is driven to move upward by the jacking drive 23. The upper load-bearing beam 211 drives the tower crane 300 to be in an inclined state before the construction begins through the support bracket 11, which provides a margin for the inclination of the tower crane 300 during the construction of the cable tower 200, thereby reducing the number of times the inclination of the tower crane 300 is adjusted during the subsequent construction of the cable tower 200, thereby improving the construction rate. During the construction of the cable tower 200, when the inclination of the tower crane 300 is too large, the inclination of the tower crane 300 can be further adjusted by driving the second end of the upper load-bearing beam 211 upward by the jacking drive 23, so as to ensure the smooth construction of the cable tower 200.

[0061] Both the support bracket 11 and the anchor bracket 21 are plane truss structures, which have the characteristics of flexible structural arrangement, so as to facilitate reasonable arrangement according to specific conditions at the construction site; the connecting beam assembly 12 not only connects multiple support brackets 11 into a whole, but also connects the anchor bracket 21 with the support bracket 11 into a whole, so that the anchor bracket 21 and the support bracket 11 can be coordinated in force. Compared with the existing cantilever tower crane 300 foundation, the adaptive tower crane foundation 100 provided by the present invention can apply an upward pulling force to the anchor bracket 21 during the construction of the cable tower 200 through the elastic inclined brace 22, and the pulling force can offset part of the load of the tower crane 300 on the support bracket 11, thereby reducing the load on the cantilever end of the anchor bracket 21 and the support bracket 11 and the whole thereof, so that the anchor bracket 21 and the support bracket 11 can reach the bearing capacity of the existing tower crane 300 foundation with less material, thereby reducing the construction cost. Furthermore, the reduction in weight of the adaptive tower crane foundation 100 can not only reduce the anchor tension of the adaptive tower crane foundation 100 on the cable tower 200, but also reduce the number of connection positions between the adaptive tower crane foundation 100 and the cable tower 200, thereby reducing the degree of damage to the cable tower 200 caused by the adaptive tower crane foundation 100.

[0062] In this embodiment, refer to Figure 2 and Figure 4The elastic inclined brace 22 is a steel cable. The elastic inclined brace 22 includes two connected sections. The first section is located above the upper load-bearing beam 211, and the second section is located between the upper load-bearing beam 211 and the lower load-bearing beam 212. The first section is inclined and the second section extends vertically.

[0063] Exemplarily, the support mechanism 1 and the anchor bracket 21 are both made of steel, which has the characteristics of light weight and high strength.

[0064] Optionally, see Figure 1 , Figure 2 and Figure 3The support bracket 11 includes a support beam 111, a first oblique support member 112 and a plurality of first inner support members 113. The support beam 111 extends along the second direction and can be anchored to the cable tower 200. One end of the first oblique support member 112 is fixedly connected to the support beam 111, and the other end is located below the support beam 111 and anchored to the cable tower 200. The support beam 111, the first oblique support member 112 and the cable tower 200 enclose a triangular first support space, and a plurality of first inner support members 113 are all arranged in the first support space to divide the first support space into a plurality of triangular units; the connecting beam assembly The component 12 includes a plurality of first connecting beams 121 and a plurality of second connecting beams 122, the first connecting beams 121 and the second connecting beams 122 both extend along the first direction, the plurality of first connecting beams 121 are arranged at intervals along the second direction, the plurality of second connecting beams 122 are arranged at intervals along the extension direction of the first oblique supporting component 112, the supporting beams 111 of the plurality of supporting brackets 11 are connected through the first connecting beams 121, the first oblique supporting components 112 of the plurality of supporting brackets 11 are connected through the second connecting beams 122, and the legs 301 of the tower crane 300 are detachably installed at the connection between the supporting beams 111 and the first connecting beams 121. The support beam 111 is a cantilever beam, and the first oblique support member 112 can support the cantilevered end of the support beam 111, so that the support beam 111 is not easily deformed under the load of the tower crane 300; the first support space formed by the support beam 111, the first oblique support member 112 and the cable tower 200 is a triangle, which has a certain stability in itself. The setting of the first inner support member 113 enables the first support space to be divided into multiple triangular units, thereby forming a plane truss-type support bracket 11 to stably support the tower crane 300. The first connecting beam 121 connects multiple support beams 111, and the second connecting beam 122 connects multiple first oblique support members 112, so as to connect multiple support brackets 11 as a whole, forming a truss-type support mechanism 1 to ensure the bearing capacity of the adaptive tower crane foundation 100; the first connecting beam 121 is perpendicular to the extension direction of the support beam 111, so that the installation plane of the tower crane 300 leg 301 formed by the first connecting beam 121 and the support beam 111 is divided into multiple grids, thereby improving the bearing capacity of the installation plane of the tower crane 300 leg 301; and, because the bearing capacity is the largest at the intersection of the grids, the leg 301 of the tower crane 300 is installed at the connection between the support beam 111 and the first connecting beam 121 to ensure the stability of the tower crane 300.

[0065] Specifically, see Figure 2 and Figure 3There are two supporting brackets 11, four first inner supporting members 113, the four first inner supporting members 113 divide the first supporting space into four small triangular units, three first connecting beams 121 are provided, two second connecting beams 122 are provided, and one first connecting beam 121 is located at the connection between the supporting beam 111 and the first oblique supporting member 112, and the two legs 301 of the tower crane 300 are installed at the connection between the supporting beam 111, the first connecting beam 121 and the first oblique supporting member 112, so that the supporting mechanism 1 can support the tower crane 300 more stably.

[0066] In this embodiment, refer to Figure 1 and Figure 5 A first mounting plate 3011 and a plurality of first support plates 3012 arranged at intervals along the circumference thereof are provided at the bottom of the tower crane 300 leg 301, the first mounting plate 3011 is placed horizontally, the first support plate 3012 is placed vertically and fixedly connected to the first mounting plate 3011; the adaptive tower crane foundation 100 also includes a leg mounting assembly 3, the leg mounting assembly 3 includes a support column 31, a second mounting plate 32 and a plurality of second support plates 33, the support column 31 has the same cross-sectional size as the tower crane 300 leg 301, the second mounting plate 32 is placed horizontally, the plurality of second support plates 33 are arranged at intervals along the circumference of the support column 31, and correspond one to one with the plurality of first support plates 3012, the upper end of the second support plate 33 and the upper end of the support column 31 are fixedly connected to the second mounting plate 32, and the lower end of the second support plate 33 and the lower end of the support column 31 are fixed to the top of the support beam 111. When installing the tower crane 300, first align the support column 31 with the leg 301 of the tower crane 300, stack the first mounting plate 3011 and the second mounting plate 32 up and down, and then use bolts to connect the first mounting plate 3011 and the second mounting plate 32. When disassembling the tower crane 300, just remove the bolts.

[0067] Exemplarily, the leg mounting assembly 3 is made of steel, the leg mounting assembly 3 is welded or bolted to the support beam 111, and the various components of the leg mounting assembly 3 are connected by welding.

[0068] Optionally, see Figure 3 and Figure 6 The support beam 111 is a hollow structure. A reinforcing plate 1111 is provided at the connection between the support beam 111 and the leg 301 of the tower crane 300. The reinforcing plate 1111 is located in the inner cavity of the support beam 111 and is fixedly connected to the inner wall of the support beam 111 to support the support beam 111, increase the load-bearing capacity of the support beam 111, and improve the stability of the support beam 111.

[0069] In this embodiment, refer to Figure 3 and Figure 6The support beam 111, the first oblique support member 112, the first connecting beam 121 and the second connecting beam 122 are all box-type structures formed by welding two I-beams. The box-type structure has extremely high torsional rigidity and bending resistance while reducing the amount of materials used. Even if the tower crane 300 has a large self-weight, the support mechanism 1 can still stably support it. The reinforcing plate 1111 is a rectangular steel plate and has the same height as the web of the I-beam. The upper and lower ends of the reinforcing plate 1111 are respectively welded to the upper and lower flanges of the I-beam, and the side of the reinforcing plate 1111 is welded to the web of the I-beam.

[0070] Further, see Figure 6 A C-shaped opening is formed on both sides of the support beam 111 formed by welding two I-beams. To further improve the bearing capacity of the support beam 111, a sealing plate 1112 having the same height as the I-beam is provided at the C-shaped opening to seal the C-shaped opening. Specifically, the sealing plate 1112 is made of steel, and the upper and lower ends of the sealing plate 1112 are respectively welded to the upper and lower flanges of the I-beam.

[0071] Optionally, see Figure 2 and Figure 4 The anchor bracket 21 also includes a connecting column 213, a second oblique support member 214 and a plurality of second inner support members 215. The second end of the upper load-bearing beam 211 is connected to the lower load-bearing beam 212 through the connecting column 213. One end of the second oblique support member 214 is connected to the upper load-bearing beam 211, and the other end is located below the lower load-bearing beam 212 and anchored to the cable tower 200. The lower load-bearing beam 212 is fixedly connected to the second oblique support member 214. The upper load-bearing beam 211, the second oblique support member 214 and the cable tower 200 enclose a triangular second support space. A plurality of second inner support members 215 are all arranged in the second support space to divide the second support space into a plurality of triangular units. The upper load-bearing beam 211 and the lower load-bearing beam 212 are both cantilever structures, and the connecting column 213 can connect the cantilevered ends of the upper load-bearing beam 211 and the lower load-bearing beam 212, thereby improving the stability of the upper load-bearing beam 211 and the lower load-bearing beam 212, so that the cantilevered end of the lower load-bearing beam 212 is not easily bent under the gravity of the jacking drive member 23; the second support space formed by the upper load-bearing beam 211, the second oblique support member 214 and the cable tower 200 is a triangle, which itself has a certain stability. The setting of the second inner support member 215 enables the second support space to be divided into multiple small triangular units, thereby forming a truss-type anchor bracket 21 to ensure the stability of the anchor mechanism 2 during anchoring.

[0072] In this embodiment, refer to Figure 1 , Figure 3 and Figure 4The cross-sectional shape of the anchor bracket 21 is the same as that of the supporting bracket 11. The two ends of the first connecting beam 121 are respectively connected to the upper load-bearing beams 211 on both sides, and the two ends of the second connecting beam 122 are respectively connected to the second oblique support members 214 on both sides, so as to connect the supporting mechanism 1 and the anchor structure into a whole, thereby improving the overall stiffness of the adaptive tower crane foundation 100.

[0073] Further, see Figure 1 , Figure 3 and Figure 4 The length of the upper load-bearing beam 211 is greater than the length of the supporting beam 111. The anchoring mechanism 2 also includes a first edge-sealing beam 241 and a second edge-sealing beam 242, both extending along the first direction. The first edge-sealing beam 241 and the second edge-sealing beam 242 are both located at one end of the anchoring bracket 21 away from the cable tower (not shown in the figure). The upper load-bearing beams 211 of the two anchoring brackets 21 are connected by the first edge-sealing beam 241, and the lower load-bearing beams 212 of the two anchoring brackets 21 are connected by the second edge-sealing beam 242. The first edge-sealing beam 241 and the second edge-sealing beam 242 not only enhance the integrity of the two anchoring brackets 21, but also limit the displacement of the upper load-bearing beam 211 and the lower load-bearing beam 212 along the first direction, thereby further ensuring the stability of the structure of the adaptive tower crane foundation 100.

[0074] Optionally, see Figure 4 and Figure 7 The upper load-bearing beam 211 is a hollow structure. The inner cavity of the upper load-bearing beam 211 is provided with a support tube 2111 extending in the vertical direction. The support tube 2111 is clamped between the top surface and the bottom surface of the upper load-bearing beam 211, and the elastic inclined member 22 is passed through the support tube 2111. The upper load-bearing beam 211 is a hollow structure, which can reduce the deadweight of the upper load-bearing beam 211, reduce the manufacturing cost of the upper load-bearing beam 211 and the external force exerted on the cable tower 200; the extension direction of the elastic inclined brace 22 changes at the top surface of the upper load-bearing beam 211, and the stretched elastic inclined brace 22 will exert a certain force on the top surface of the upper load-bearing beam 211. The support tube 2111 is clamped between the top and bottom surfaces of the upper load-bearing beam 211. The upper and lower ends of the support tube 2111 can respectively support the top and bottom surfaces of the upper load-bearing beam 211 to resist the action force of the above-mentioned elastic inclined brace 22 and prevent the upper load-bearing beam 211 from deformation.

[0075] Specifically, the upper load-bearing beam 211, the lower load-bearing beam 212 and the second oblique support member 214 are also box-shaped structures formed by welding two I-beams, see Figure 7 The support tube 2111 is a steel tube, and the support tube 2111 is located between the webs of two I-beams.

[0076] Further, see Figure 2 and Figure 7The upper load-bearing beam 211 is provided with a plurality of gusset plates 2112 arranged at intervals along its extending direction. The gusset plates 2112 are welded to the flanges of two I-beams. The arrangement of the gusset plates 2112 enables the upper load-bearing beam 211 to form a lattice structure, thereby enhancing the overall stability of the upper load-bearing beam 211 and preventing the upper load-bearing beam 211 from being deformed or unstable under the action of external force.

[0077] For example, see Figure 4 and Figure 8 The lifting drive member 23 is a hydraulic jack, the elastic inclined member 22 is a plurality of steel cables, and an annular plate 25 is provided on the bottom surface of the upper load-bearing beam 211. One end of the plurality of steel cables is connected to the cable tower (not shown in the figure), and the other end passes through the upper load-bearing beam 211, the annular plate 25 and the hydraulic jack in sequence and is anchored to the lower load-bearing beam 212. The provision of the annular plate 25 facilitates the connection between the piston rod of the hydraulic jack and the upper load-bearing beam 211, and can also increase the connection area between the hydraulic jack and the upper load-bearing beam 211, thereby preventing the upper load-bearing beam 211 from being damaged during the lifting process.

[0078] Furthermore, an anchor plate 54 is provided on the lower load-bearing beam 212, and a plurality of holes are provided on the anchor plate 54. A plurality of steel cables are movable through the plurality of holes one by one so as to adjust the length of the steel strand between the lower load-bearing beam 212 and the cable tower 200 during installation, and the anchor plate 54 can also lock the steel strand to maintain the current length of the steel strand.

[0079] Optionally, see Figure 4 and Fig. 9 A steering member 26 is provided on the upper load-bearing beam 211, and an arc-shaped through-hole is provided on the steering member 26. The elastic diagonal brace member 22 is penetrated through the through-hole to change the extension direction of the elastic diagonal brace member 22, so that the elastic diagonal brace member 22 can provide an oblique tensioning force while being connected to the anchor bracket 21.

[0080] For example, the steering member 26 is a cable saddle, which is provided with a plurality of holes, and a plurality of steel cables are correspondingly passed through the plurality of holes. The cross section of the holes is circular, and an arc-shaped notch is provided at the upper end of the holes to match the change of the angle between the first section and the second section of the elastic inclined member 22.

[0081] In this embodiment, an upper mounting plate 27 is provided on the top surface of the upper load-bearing beam 211, and the steering member 26 is fixed to the upper mounting plate 27. A through hole is provided on the upper mounting plate 27, and the elastic inclined member 22 passes through the steering member 26, the through hole and the support tube 2111 in sequence. In this embodiment, the upper load-bearing beam 211 is a structure composed of two I-beams. The setting of the upper mounting plate 27 facilitates the installation of the steering member 26 on the upper load-bearing beam 211.

[0082] Further, see Figure 8 and Fig.10A plurality of stiffening end plates 281 and a plurality of stiffening ribs 282 are provided on the annular plate 25 and the upper mounting plate 27. The stiffening end plates 281 and the stiffening ribs 282 are vertically placed and extend along the first direction. The stiffening end plates 281 are located on both sides of the annular plate 25 or the upper mounting plate 27 along the second direction, and the stiffening ribs 282 are located on both sides of the annular plate 25 or the upper mounting plate 27 along the first direction to enhance the strength of the upper load-bearing beam 211 at the connection between it and the jacking drive member 23 and the steering member 26.

[0083] Optionally, see Figure 1 , Figure 2 and Fig.11 The adaptive tower crane foundation 100 further includes an anchor 41 and a connecting bolt 42. The anchor 41 is buried in the cable tower 200. The support bracket 11 or the anchor bracket 21 is connected to the anchor 41 by the connecting bolt 42 to fix the adaptive tower crane foundation 100 to the cable tower 200. The anchor 41 is buried in the concrete cable tower 200, which can effectively connect the anchor 41 and the concrete tightly together to ensure the anchoring effect; the support bracket 11 or the anchor bracket 21 is connected to the anchor 41 by the connecting bolt 42, so as to facilitate the installation and removal of the support bracket 11 or the anchor bracket 21 on the cable tower 200, thereby improving the construction efficiency.

[0084] In this embodiment, refer to Fig.11 The anchor 41 includes a threaded portion, and a threaded sleeve 43 is provided at the end of the anchor 41. The threaded portion and the connecting bolt 42 are both threadedly matched with the threaded sleeve 43, and the thread of the threaded portion is in the opposite direction to the thread of the connecting bolt 42. The thread can increase the friction between the anchor 41 and the concrete, further improving the firmness of the connection between the anchor 41 and the concrete; the setting of the threaded sleeve 43 realizes the threaded connection between the connecting bolt 42 and the anchor 41, and the thread of the threaded portion is in the opposite direction to the thread of the connecting bolt 42, so that when the connecting bolt 42 is screwed, the threaded sleeve 43 and the threaded portion will not rotate relative to each other, ensuring the stability of the connection between the threaded sleeve 43 and the threaded portion.

[0085] Furthermore, the support beam 111, the first oblique support member 112, the upper load-bearing beam 211 and the second oblique support member 214 are all anchored to the cable tower 200 through a plurality of anchors 41 and a plurality of connecting bolts 42, and the plurality of anchors 41 and the plurality of connecting bolts 42 correspond to each other. The ends of the support beam 111, the first oblique support member 112, the upper load-bearing beam 211 and the second oblique support member 214 are all provided with connecting plates 44, which are embedded in the cable tower 200, and a plurality of connecting bolts 42 pass through the connecting plates 44 and are threadedly connected with corresponding threaded sleeves 43, and the connecting plates 44 can enhance the integrity between the plurality of anchors 41, and improve the strength of the connection between the adaptive tower crane foundation 100 and the cable tower 200.

[0086] Optionally, see Figure 1 , Figure 4 and Fig.12 The adaptive tower crane foundation 100 also includes an axle pin and a first connecting ear plate 51 that can be anchored to the cable tower 200. A second connecting ear plate 52 is provided at one end of the elastic diagonal member 22 away from the upper load-bearing beam 211. The first connecting ear plate 51 and the second connecting ear plate 52 are rotatably connected by the axle pin, so that the first connecting ear plate 51 and the second connecting ear plate 52 can rotate relative to each other, that is, the angle between the elastic diagonal member 22 and the cable tower 200 can be changed to match the inclination of the upper load-bearing beam 211.

[0087] Specifically, see Figure 4 and Fig.12 A box-type connecting pipe 53 is provided at one end of the elastic inclined brace 22 away from the upper load-bearing beam 211, and an anchor plate 54 is provided in the box-type connecting pipe 53. The steel cable is fixed to the box-type connecting pipe 53 through the anchor plate 54, and the second connecting ear plate 52 is fixed to the end of the box-type connecting pipe 53 away from the steel cable.

[0088] In this embodiment, refer to Fig.12 The cross-sectional shape of the first connecting ear plate 51 is a corbel shape, the elastic diagonal brace 22 is connected to the corbel portion of the first connecting ear plate 51, and the corbel portion and the elastic diagonal brace 22 are located in the same straight line, thereby improving the bearing capacity of the first connecting ear plate 51. The manner in which the first connecting ear plate 51 is anchored to the cable tower 200 is the same as that of the upper load-bearing beam 211, and will not be repeated here. In other embodiments, the cross-sectional shape of the first connecting ear plate 51 is a rectangle, a parallelogram, etc.

[0089] Embodiment 2

[0090] like Fig.13 As shown, this embodiment provides a method for using an adaptive tower crane foundation 100, using the adaptive tower crane foundation 100 of the first embodiment to support a tower crane 300, specifically comprising the following steps:

[0091] S1. Install the supporting mechanism 1 on the cable tower 200 , and install the tower crane 300 on the supporting mechanism 1 .

[0092] Specifically, the installation position of the support mechanism 1 on the cable tower 200 is determined, and the anchor 41 is buried at the installation position; then, the support beam 111 of the support bracket 11 and the first oblique support member 112 are connected to the anchor 41; finally, the tower crane 300 is moved to the top of the support mechanism 1, and the leg 301 of the tower crane 300 is connected to the leg mounting assembly 3 on the support beam 111.

[0093] S2. Install the anchoring mechanism 2 on the cable tower 200 and connect the anchoring bracket 21 and the connecting beam assembly 12.

[0094] Specifically, the first connecting ear plate 51, the upper load-bearing beam 211 and the second oblique support member 214 are connected to the cable tower 200 by using the anchor 41, and the anchor bracket 21 is connected to the first connecting beam 121 and the second connecting beam 122; then, the anchor plate 54 and the jacking drive member 23 are installed on the lower load-bearing beam 212, the second connecting ear plate 52 at one end of the elastic oblique member 22 is connected to the first connecting ear plate 51, and the other end of the elastic oblique member 22 is passed through the steering member 26, the upper mounting plate 27, the support tube 2111, the annular plate 25 and the jacking drive member 23 in sequence, and fastened to the anchor plate 54 on the lower load-bearing beam 212; finally, each connection node of the adaptive tower crane foundation 100 and the connection between the adaptive tower crane foundation 100 and the cable tower 200 are inspected to ensure the firmness of the connection of each connection node.

[0095] S3. See Figure 3 and Figure 4 The jacking driving member 23 is controlled to drive the second end of the upper load-bearing beam 211 to move upward by a preset distance, and pull the elastic inclined member 22.

[0096] Specifically, see Figure 4 In the orientation, after the second end of the upper load-bearing beam 211 moves upward by a preset distance, the right side of the upper load-bearing beam 211 is higher than the left side, and the upper load-bearing beam 211 drives the support mechanism 1 to move upward as a whole, and the tower crane 300 located on the support mechanism 1 is tilted, and at the same time, the length of the elastic inclined brace 22 is changed by pulling the elastic inclined brace 22. Such operation can pre-tension the elastic inclined brace 22 before the lifting operation begins, so that the elastic inclined brace 22 can apply an upward pulling force to the anchor bracket 21 during the construction of the cable tower 200; on the other hand, it also causes the tower crane 300 to tilt before the lifting operation begins, providing a certain margin for the tilt of the tower crane 300 during the construction of the cable tower 200.

[0097] The preset distance is determined according to the structure of the tower crane 300 and the structure of the adaptive tower crane foundation 100. As long as the upper load-bearing beam 211 moves the preset distance, the inclination of the tower body of the tower crane 300 is less than 4 / 1000.

[0098] S4. Control the tower crane 300 to perform the hoisting operation, and monitor the vertical movement distance of the second end of the upper load-bearing beam 211 to determine whether the inclination degree of the tower body of the tower crane 300 exceeds the limit.

[0099] Specifically, during the operation of the tower crane 300, part of the force of the tower crane 300 is transmitted to the cable tower 200 through the support mechanism 1, and the other part of the force is transmitted to the cable tower 200 through the anchor bracket 21, thereby reducing the material consumption while still improving the bearing capacity of the adaptive tower crane foundation 100.

[0100] S5. Determine whether the second end of the upper load-bearing beam 211 moves downward by a preset distance relative to the horizontal plane. If so, control the tower crane 300 to stop the lifting operation, and repeat steps S3 and S4 until the construction of the cable tower 200 is completed; if not, repeat step S4 until the construction of the cable tower 200 is completed.

[0101] When the second end of the upper load-bearing beam 211 moves downward a preset distance relative to the horizontal plane, the inclination of the tower body of the tower crane 300 is too large. If the tower crane 300 continues to be used, it is easy to overturn. Therefore, at this time, by executing step S3 to lift the upper load-bearing beam 211 again, the upper load-bearing beam 211 can drive the supporting mechanism 1 to return to a horizontal state, thereby making the tower body of the tower crane 300 return to the upright state. By pulling the elastic inclined brace 22, the anchor bracket 21 can still be subjected to an upward pulling force to ensure the safety of subsequent construction.

[0102] S6. Remove the tower crane 300 and the adaptive tower crane foundation 100 from the cable tower 200.

[0103] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the embodiments of the present invention. For those skilled in the art, various obvious changes, readjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to list all the embodiments here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the claims of the present invention.
