Description
Technical Field
[0001] The present invention relates to the technical field of lifting equipment, and particularly to a tower base adjustment structure for enhancing the stability of the tower base and the tower body. Background Art
[0002] The tower crane foundation is the foundation for the safe and stable operation of tower cranes. Its technical background is closely related to the requirements of engineering practice. In the early days of building construction, simple concrete block structures were mostly used for tower crane foundations, which only met the basic bearing requirements but lacked adaptability to complex geological conditions and load changes, and were prone to safety hazards due to problems such as foundation settlement and insufficient anti-overturning ability. With the increase in high-rise buildings and large-scale projects, the loads of tower cranes have been continuously increasing, posing higher requirements for the design and construction of foundations. Modern tower crane foundations need to comprehensively consider geological exploration data (such as soil bearing capacity, groundwater level, etc.), tower crane models and working parameters (lifting capacity, boom length, overturning moment, etc.), and the construction site environment (surrounding buildings and structures, underground pipeline distribution), and through mechanical calculations and structural optimization design, form more scientific foundation forms, such as raft foundations, pile foundations, combined foundations, etc. Among them, pile foundations transfer loads to stable soil layers through deep pile foundations and are suitable for soft foundations; combined foundations combine precast components and on-site casting to improve construction efficiency and the integrity of the foundation. At the same time, the construction technology has also developed from traditional on-site casting to modularization and assembly. Through technical means such as embedding anchor bolts and setting settlement observation points, the accuracy and long-term stability of the foundation are ensured.
[0003] However, during the use of the current tower base in cooperation with the tower crane, sometimes due to the influence of the external harsh environment, the top of the tower base may shake. Under the action of long-term or continuous external forces, the shaking tower crane body will pull on the connection position with the tower base, causing the screw connected to the tower crane to tilt with the tower crane body, and it is very easy to occur the situation of the tower crane tilting and the verticality deteriorating, and ultimately may cause the serious consequence of the tower crane overturning.
[0004] Therefore, a tower base adjustment structure for enhancing the stability of the tower base and the tower body is proposed. Summary of the Invention

[0016] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.
[0017] Please refer to Figures 1 to 11 , the present invention provides a technical solution for a tower base adjustment structure for enhancing the stability of the tower base and the tower body: A tower base adjustment structure for enhancing the stability of the tower base and the tower body, comprising: Tower base structure 1, mainly composed of lattice columns / trusses, foundation base plates / raft foundations, connecting members, foundation treatment and cushions, and accessory structures, is a structural foundation form that transfers the upper load to the foundation through rigid connections; Tower body structure 2, which is the main structure of the tower crane, is installed and fixed on the foundation base plate / raft foundation of the tower base structure 1 by using bolts through the reserved screws; Tower base auxiliary structure 3, which has four arms and is located directly below the tower body structure 2, and is slidably connected to the four legs of the tower body structure 2 in cooperation with the four arms; Among them, the tower base auxiliary structure 3 includes a crank arch seat 31. The crank arch seat 31 is an X-shaped upper arched frame structure with four S-shaped arm bodies, enabling the tower base auxiliary structure 3 to better disperse and bear the forces from all directions of the tower body, enhancing the overall stability of the structure and its adaptability to different load distributions. And there is a support platform for installation at the central position. Among them, socket handles 33 are fixedly arranged at the ends of the four arm bodies, and a hydraulic tank 32 and a water pumping cylinder 34 are respectively connected to the upper and lower surfaces of the support platform by bolts; Among them, a hydraulic spring piston 321 is slidably sealed inside the hydraulic tank 32, and a safety liquid is stored above the piston of the hydraulic spring piston 321 inside the hydraulic tank 32. The hydraulic spring piston 321 is composed of a piston rod and a spring sleeved on the piston rod, and the upper and lower ends of the spring respectively press against the surface of the piston of the hydraulic spring piston 321 and the upper part inside the hydraulic tank 32. And the upper end of the piston rod penetrates out of the hydraulic tank 32. Upper liquid nozzles 322 for outputting the safety liquid are arranged in an annular array along the axis above the side surface of the hydraulic tank 32. A first single-hook connection seat 323 is installed on the upper end of the hydraulic spring piston 321 by bolts, and at least two steel wire ropes 324 are inserted into the ring structure of the first single-hook connection seat 323. And the upper ends of the steel wire ropes 324 are inserted into the ring structure of the second single-hook connection seat 325. The second single-hook connection seats 325 are all fixedly installed on the lower surface of the upper cross beam of the tower body structure 2 by bolts and are symmetrically distributed; A docking groove 331 facilitating the sliding connection with the four feet of the tower body structure 2 is opened at the central position inside the socket handle 33. And a specified number of screw holes 332 for corresponding installation of screws are opened on the periphery of the docking groove 331 inside the socket handle 33. At the middle position of the inner wall of each screw hole 332, a wheel groove communicating with the screw hole 332 is symmetrically opened along the axis. And a ratchet gear 334 is slidably arranged inside the wheel groove in cooperation with a chute opened on the inner wall of the wheel groove. A shaft wheel 335 is rotatably sleeved on the wheel shaft of the ratchet gear 334 on the side close to the shunt liquid channel 333. And a hydraulic spring 337 is fixedly arranged on the side surface of the shaft wheel 335. And one end of the hydraulic spring 337 is fixed on the inner wall on the side opposite to the shaft wheel 335 of the chute. A liquid pushing piston 336 is fixedly arranged on the wheel surface of the shaft wheel 335 on the side opposite to the hydraulic spring 337. And the piston end of the liquid pushing piston 336 slidably seals and penetrates into the inside of the shunt liquid channel 333. The shunt liquid channel 333 is opened inside the socket handle 33 and on the side close to the axis. The pore path of the shunt liquid channel 333 is in the shape of a three-dimensional coordinate system, and one end of the shunt liquid channel 333 extends upward through the socket handle 33 and is fixedly communicated with the upper liquid nozzle 322 through a pipeline.
[0018] During operation, the tower base auxiliary structure 3 is sleeved on the feet of the tower body structure 2 and then fixed to the foundation slab / bench of the tower base structure 1 through a screw. The sleeve handle 33 of the tower base auxiliary structure 3 is slidably connected to the feet. When the screw is inserted into the screw insertion hole 332 of the sleeve handle 33, the ratchet gear 334 is driven to rotate and lock the screw to prevent it from detaching. At this time, the hydraulic spring piston 321 in the hydraulic tank 32 is in the initial position, and the water pumping piston 342 in the water pumping cylinder 34 is connected to it and is at a low position; when the tower body structure 2 sways and tilts due to external forces such as strong winds, the steel wire rope 324 pulls the first single-hook connection seat 323, driving the hydraulic spring piston 321 to move upward to compress the safety liquid. The liquid flows into the flow distribution channel 333 of the sleeve handle 33, pushing the liquid push piston 336 and the shaft wheel 335. The shaft wheel 335 drives the ratchet gear 334 to slide, enhancing its positioning strength with the screw, improving the connection stability between the tower base and the tower body, and at the same time avoiding screw distortion to ensure the firm connection of each structure.
[0019] In summary, through the setting of the tower base auxiliary structure 3, when the tower body structure 2 sways due to external forces such as strong winds, the steel wire rope 324 pulls the first single-hook connection seat 323, driving the hydraulic spring piston 321 to move upward, compressing the safety liquid in the hydraulic tank 32. The liquid flows into the flow distribution channel 333 of the sleeve handle 33 through the upper liquid nozzle 322, pushing the liquid push piston 336 and the shaft wheel 335, causing the ratchet gear 334 to slide and enhancing its positioning strength with the screw, effectively reducing the influence of external forces on the tower body, improving the stability and safety of the tower base and the tower body, reducing the risk of tilting caused by swaying. At the same time, the ratchet structure of the ratchet gear 334 can lock the screw when it is inserted into the screw insertion hole 332 to prevent the screw from moving downward, and under the pulling action of the tower body, it can avoid the screw from being distorted by the influence of the tower body, ensuring the stability of the connection position of the tower base structure 1, the tower body structure 2 and the tower base auxiliary structure 3.
[0020] As an embodiment of the present invention, as Figure 5 、 Figure 8 and Figure 10 shown, a water pumping piston 342 is slidably and sealingly arranged inside the water pumping cylinder 34, and the upper end of the water pumping piston 342 passes through the water pumping cylinder 34 and enters the inside of the hydraulic tank 32 through the crank arch seat 31 and is fixed to the hydraulic spring piston 321 inside the hydraulic tank 32. A T-shaped upper water channel 343 is opened along the axis from the lower end of the water pumping piston 342 to the rod side of the water pumping piston 342, and an upper water check valve 344 opening into the upper water channel 343 is installed at the lower port of the upper water channel 343. The lower end of the water pumping cylinder 34 is spaced from the surface of the foundation slab / bench of the tower base structure 1, and an installation hole is opened at the center position of the lower surface of the water pumping cylinder 34, and a water pumping check valve 341 opening into the water pumping cylinder 34 is installed in cooperation with the installation hole. An interface for discharging water is arranged above the side of the water pumping cylinder 34, and is communicated with a pipeline for conveying accumulated water to the outside through the interface.
[0021] When the hydraulic spring piston 321 moves upward, it will synchronously pull the water pumping piston 342 upward. When the water pumping piston 342 moves upward, a negative pressure is formed inside the water pumping cylinder 34. Then the water pumping one-way valve 341 opens, sucking in the accumulated water on the surface of the foundation slab / raft foundation of the tower base structure 1. When the shaking of the tower body weakens, the hydraulic spring piston 321 resets and moves downward under the action of the spring, and the water pumping piston 342 presses downward synchronously. At this time, the water pumping one-way valve 341 closes, and when the water pumping piston 342 moves downward, it will compress the accumulated water drawn into the water pumping cylinder 34. Under continuous compression, the liquid pressure of the accumulated water will force the water inlet one-way valve 344 to open for pressure relief, pressing the sucked liquid through the water inlet liquid channel 343 into the upper part inside the hydraulic tank 32 and transporting it to a specified position outside, thereby realizing the cleaning of the accumulated water on the tower base structure 1.
[0022] To sum up, through the setting of the tower base auxiliary structure 3, when the hydraulic spring piston 321 moves upward, the water pumping piston 342 moves upward synchronously to form a negative pressure inside the water pumping cylinder 34, sucking in the accumulated water on the surface of the foundation slab / raft foundation of the tower base structure 1 through the water pumping one-way valve 341; when the shaking of the tower body weakens and the hydraulic spring piston 321 resets and moves downward, the water pumping piston 342 presses downward, compressing the accumulated water in the water pumping cylinder 34, forcing the water inlet one-way valve 344 to open, and pressing the accumulated water through the water inlet liquid channel 343 into the upper part inside the hydraulic tank 32 and transporting it to a specified position outside, realizing the automatic cleaning of the accumulated water on the tower base surface, avoiding the corrosion of the tower base structure 1 caused by the accumulated water, and ensuring the long-term stability of the tower base.
[0023] Working principle: During operation, first, the tower base auxiliary structure 3 is sleeved on each leg of the tower body structure 2 in a bottom-up manner in cooperation with the docking groove 331 opened inside the crank arch seat 31. Then, the tower body structure 2 and the tower base auxiliary structure 3 are fixed to the foundation slab / raft foundation of the tower base structure 1 by screws. The four sleeve handles 33 of the tower base auxiliary structure 3 are respectively slidably connected to the four legs of the tower base auxiliary structure 3. During the installation process, the screws on the tower body structure 2 will be correspondingly inserted into their respective screw insertion holes 332. At this time, the ratchet gear 334 will contact the screw inserted into the inside of the screw insertion hole 332, and during the process of the screw being inserted into the screw insertion hole 332, it will be driven to rotate by the screw. Since the ratchet gear 334 is a ratchet structure, the ratchet gear 334 will use the teeth on its surface to lock the screw, preventing the screw from moving downward out of the screw insertion hole 332 and separating from the sleeve handle 33. At this time, the hydraulic spring piston 321 inside the hydraulic tank 32 is in the initial position under the action of the spring, and the safety liquid is stored on the upper side of the piston. The water pumping piston 342 inside the water pumping cylinder 34 is fixedly connected to the hydraulic spring piston 321 and is in the low position. When the tower body structure 2 is shaken and tilted by external forces such as strong winds and sudden changes in loads, the first single-hook connecting seat 323 is pulled by the steel wire rope 324, driving the hydraulic spring piston 321 to move upward. When the hydraulic spring piston 321 moves upward, it compresses the safety liquid, forcing the liquid to flow from the upper liquid nozzle 322 on the side of the hydraulic tank 32 into the shunt liquid channel 333 of the sleeve handle 33 through the pipeline. The liquid pressure in the shunt liquid channel 333 pushes the liquid push piston 336 to move along the shunt liquid channel 333, and pushes the shaft wheel 335 to compress the hydraulic spring 337. At the same time, the shaft wheel 335 drives the ratchet gear 334 to slide in the wheel groove and gradually contacts the side of the screw inserted into the screw jack 332, further enhancing the positioning strength between the ratchet gear 334 and the screw. In this way, it can cooperate with the hydraulic tank 32, the hydraulic spring piston 321, the first single-hook connecting seat 323 and the steel wire rope 324 to increase the connection stability between the tower body and the tower foundation, effectively reducing the influence of external forces on the tower body, and being more conducive to improving the stability and safety of the tower foundation and the tower body. In addition, in cooperation with the ratchet gear 334, under the pulling action of the tower body, it can effectively prevent the screw from being distorted under the influence of the tower body, ensuring the stability of the connection positions of the tower foundation structure 1, the tower body structure 2 and the tower foundation auxiliary structure 3; When the hydraulic spring piston 321 moves upward, it will simultaneously pull the water pumping piston 342 to move upward. Since the space of the water pumping cylinder 34 below the water pumping piston 342 increases as the water pumping piston 342 moves upward, in the absence of other substances being replenished, the upward movement of the water pumping piston 342 creates a negative pressure inside the water pumping cylinder 34. Then, under the action of negative pressure adsorption, the water pumping one-way valve 341 will be opened passively, sucking the accumulated water on the surface of the tower foundation structure 1 from the surface of the foundation slab / raft of the tower foundation structure 1. When the shaking of the tower body weakens, the hydraulic spring piston 321 resets and moves downward under the action of the spring, and the water pumping piston 342 presses downward synchronously. At this time, the water pumping one-way valve 341 closes, and when the water pumping piston 342 moves downward, it will compress the accumulated water drawn into the water pumping cylinder 34. Under continuous compression, the liquid pressure of the accumulated water will force the upward water one-way valve 344 to open for pressure relief, pressing the sucked liquid into the upper part of the internal hydraulic tank 32 through the upward liquid channel 343 and transporting it to a specified position outside through the specified output pipeline. In this way, the cleaning of the accumulated water on the tower foundation structure 1 can be realized; When there is no influence of bad weather, the tower foundation structure 1, the tower body structure 2 and the tower foundation auxiliary structure 3 will be in a relatively stable connection state at the initial time (such as Figure 1 ). In addition, this structure also has the advantages of simple structure, convenient installation, high reliability, long service life, etc., and can be widely applied to various tower foundation engineering fields.
