Description

Technical Field

[0001] This utility model relates to the field of tower crane technology, specifically to a self-draining tower crane foundation structure. Background Technology

[0002] In the construction industry, tower cranes are core lifting equipment, and the stability and durability of their foundation structures directly affect construction safety and efficiency. Currently, most conventional tower crane foundations in the industry use concrete cast-in-place bases, relying solely on simple drainage slopes to channel rainwater. There are no specialized treatment structures designed for the cement water and cement block mixed wastewater generated during construction, resulting in a relatively rudimentary overall drainage and wastewater management system.

[0003] Existing technologies have significant limitations: Firstly, rainwater and cement wastewater easily accumulate on the base surface and at the bottom of the tower crane. The corrosive components in the wastewater continuously erode the metal structure of the tower crane, shortening its service life. Furthermore, the uncontrolled flow of wastewater pollutes the construction environment. Secondly, the lack of effective interception and recycling mechanisms for cement blocks and fine particles in the wastewater not only wastes cement resources but also causes particle buildup that clogs drainage channels, further exacerbating the water accumulation problem. In addition, while some improvement solutions include simple water collection tanks, they lack tiered filtration and sedimentation structures, making water recycling impossible. Moreover, the challenges of cleaning clogged filters are not considered, hindering long-term stable operation.

[0004] While the industry has attempted to optimize the system by adding drainage holes and laying impermeable layers, a fully integrated solution encompassing "drainage-filtration-sedimentation-recycling" has yet to be developed. This has resulted in the inability to effectively meet the demands for corrosion protection, stability improvement, and resource conservation in tower crane foundations. Against this backdrop, there is an urgent need for a tower crane foundation structure that can automatically drain construction wastewater, protect the tower crane structure, enhance foundation stability, and also possess resource recycling capabilities, in order to address the shortcomings of existing technologies. Utility Model Content

[0005] (a) Technical problems to be solved In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide a self-draining tower crane foundation structure, which effectively solves the problem that the existing devices cannot automatically drain rainwater and construction sewage.

[0006] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: A self-draining tower crane foundation structure includes a base, on which the tower crane body is mounted, and on one side of the base a water collection trough. The upper part of the base is provided with a sewage storage chamber, which is used to treat sewage; The upper part of the base is provided with a water guiding mechanism, which corresponds to the sewage storage chamber and is used to guide the sewage.

[0007] Preferably, the wastewater storage chamber is divided into a filtration section and a sedimentation section, with the filtration section located at the bottom of the sedimentation section.

[0008] Preferably, the top of the filter section is detachably connected to an iron mesh, and the bottom of the filter section is fixedly connected to a filter plate.

[0009] Preferably, the water guiding mechanism consists of an installation position and a guide groove; The mounting position is located on the upper part of the base, and several reinforcing ribs are fixedly connected around the mounting position. The mounting position and the bottom of the reinforcing ribs are detachably connected by expansion screws. The guide groove is also formed on the upper part of the base. One end of the guide groove is connected to the installation position, and the other end of the guide groove is connected to the sewage storage tank.

[0010] Preferably, the end of the guide channel near the sewage storage tank is lower than the end of the guide channel away from the sewage storage tank, and the guide channel is connected to the installation position.

[0011] Preferably, the water collection tank is connected to the middle of the sedimentation section via a water pipe, and a one-way valve is provided on the outside of the water pipe.

[0012] Preferably, the filter section has an installation chamber in the middle, and a dust removal device is fixedly connected inside the installation chamber; The dust removal device includes a hydraulic telescopic column and a top column. The top column is fixedly connected to the upper part of the hydraulic telescopic column, and the top of the top column corresponds to the iron mesh.

[0013] Preferably, a water level sensor is fixedly installed on one side of the sewage storage tank, and the water level sensor is used to control the extension and retraction of the hydraulic telescopic column.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a self-draining tower crane foundation structure, which has the following beneficial effects: This utility model's self-draining tower crane foundation structure, through the setting of reinforcing ribs and guide channels, allows rainwater, cement water, cement blocks, and other large particulate wastewater to flow from the tower body of the tower crane into the interior of the wastewater storage tank. This tank stores various types of wastewater, prevents the wastewater from corroding the tower crane body, achieves the function of self-drainage, and also extends the service life of the tower crane equipment.

[0015] This utility model's self-draining tower crane foundation structure, through the setting of a sewage storage tank and a water collection tank, allows sewage to pass through a filtration section inside the sewage storage tank, where cement blocks and other large particles are intercepted. The filtered sewage then enters a sedimentation section for sedimentation, causing fine cement particles in the sewage to gradually settle under gravity and eventually deposit at the bottom of the base, continuously increasing the weight of the base and thus improving the stability of the entire system. It also avoids cement waste. The water treated by the sewage storage tank flows through a water pipe into the water collection tank, facilitating water access for workers during later construction.

[0016] This utility model discloses a self-draining tower crane foundation structure. Through the installation of hydraulic telescopic columns and a top column, when the hydraulic telescopic columns begin operation, they drive the top column upwards. During the ascent of the top column, its top comes into contact with the corresponding wire mesh and applies pressure. This design effectively lifts and loosens large particles on the wire mesh surface under the continuous action of the top column, significantly reducing the accumulation and clogging of large particles on the wire mesh surface and extending the service life of the device.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0026] Example 1: This embodiment provides a self-draining tower crane foundation structure, which has the following technical features.

[0027] Please see Figure 1-4 A self-draining tower crane foundation structure includes a base 11, a tower crane body 12 installed on the upper part of the base 11, and a water collection tank 13 installed on one side of the base 11. A sewage storage chamber 15 is provided on the upper part of the base 11, and the sewage storage chamber 15 is used to treat sewage; A water guiding mechanism is provided on the upper part of the base 11. The water guiding mechanism corresponds to the sewage storage chamber 15 and is used to guide the sewage.

[0028] It should be noted that the tower crane body 12 is surrounded by a structure of multiple radially arranged reinforcing ribs 24, evenly distributed and firmly welded around its perimeter. These reinforcing ribs 24 are not only made of high-strength steel but also have a dual function in their design. First, these reinforcing ribs 24 form a strong support system for the tower crane body 12 through a triangular stabilizing structure, significantly improving the overall structural strength and wind and earthquake resistance of the tower crane. Second, each reinforcing rib 24 has a sewage diversion function. When encountering rainfall or sewage generated during construction operations, these reinforcing ribs 24 can quickly guide and divert corrosive liquids such as rainwater and lime slurry adhering to the surface of the tower crane body 12, effectively preventing sewage from lingering on the surface of the tower crane body 12 for extended periods, thereby preventing sewage from causing corrosion damage to the tower crane steel structure at the source. Specifically, during actual operation, the reinforcing rib 24 system around the tower crane body 12 will collect various types of sewage, including natural rainfall and lime slurry splashed during operation, and transport them through the bottom of the tower crane body 12 to the interior of the water diversion mechanism. The wastewater will then be directed into the wastewater storage chamber 15 located below to store various types of wastewater, providing comprehensive protection for the tower crane body 12 from wastewater corrosion and significantly extending the service life of the tower crane equipment.

[0029] In an optional embodiment, the wastewater storage tank 15 is divided into a filtration section and a sedimentation section, with the filtration section located at the bottom of the sedimentation section.

[0030] In an optional embodiment, the top of the filter section is detachably connected to an iron mesh 17, and the bottom of the filter section is fixedly connected to a filter plate 18.

[0031] It should be noted that the wastewater containing cement water, cement blocks, and other large particles generated during operation first enters the filtration section for treatment, effectively separating the cement blocks and other large particles. Subsequently, the pre-filtered wastewater enters the sedimentation section for secondary treatment, where cement particles are fully settled. Simultaneously, the deposition of cement particles further increases the overall weight of the base 11, enhancing the stability of the equipment.

[0032] In its operation, the filtration unit employs a dual filtration mechanism to ensure effective filtration. First, the wire mesh 17 intercepts large cement lumps and other large particles carried by the cement water flow, effectively preventing these particles from directly entering subsequent filtration stages and causing blockages. Then, the wastewater passes through the filter plate 18 for further filtration, removing larger particles. After these two filtration processes, solid particles in the wastewater are thoroughly removed, and the filtered wastewater enters the sedimentation unit for settling. In the sedimentation unit, fine cement particles in the cement water gradually settle under gravity, eventually depositing at the bottom of the base 11. This sedimentation process not only purifies the wastewater but also continuously increases the weight of the base 11 through the accumulation of cement deposits, thereby improving the stability of the entire system, preventing cement waste, and maximizing cement utilization.

[0033] In an optional embodiment, the water guiding mechanism consists of a mounting position 14 and a guide groove 16; Mounting position 14 is provided on the upper part of base 11. Several reinforcing ribs 24 are fixedly connected around mounting position 14. The bottom of mounting position 14 and reinforcing ribs 24 are detachably connected by expansion screws. A guide channel 16 is also provided on the upper part of the base 11. One end of the guide channel 16 is connected to the mounting position 14, and the other end of the guide channel 16 is connected to the sewage storage tank 15.

[0034] In an optional embodiment, the end of the guide groove 16 near the sewage storage tank 15 is lower than the end of the guide groove 16 away from the sewage storage tank 15, and the guide groove 16 is connected to the mounting position 14.

[0035] It should be noted that the base 11 is connected to the tower crane body 12 using expansion bolts. This connection method not only ensures the stability of the structure but also facilitates the disassembly and maintenance of the tower crane body 12 later. For drainage, reinforcing ribs 24 are provided around the tower crane body 12, guiding wastewater along these ribs into the mounting position 14 at the bottom. Since the bottom of the mounting position 14 is designed with a guide channel 16 that communicates with it, and this guide channel is inclined, it guides the wastewater to flow naturally to the wastewater storage tank 15. The wastewater is ultimately stored centrally in the wastewater storage tank 15, preventing corrosion of the tower crane body 12.

[0036] In an optional embodiment, the water collection tank 13 is connected to the middle of the sedimentation section via a water pipe, and a one-way valve 23 is provided on the outside of the water pipe.

[0037] It should be noted that after the wastewater in the sedimentation section settles, the cement remains at the bottom of the sedimentation section, while the water flows through the water pipe into the interior of the water collection tank 13, which is convenient for workers to draw water during later construction. The one-way valve 23 is set to prevent the water in the water collection tank 13 from flowing back into the sedimentation section when there is too much water inside.

[0038] In an optional embodiment, an installation chamber 19 is provided in the middle of the filter section, and a dust removal device is fixedly connected inside the installation chamber 19. The dust removal device includes a hydraulic telescopic column 20 and a top column 21. The top column 21 is fixedly connected to the upper part of the hydraulic telescopic column 20, and the top of the top column 21 corresponds to the iron mesh 17.

[0039] It should be noted that when the hydraulic telescopic column 20 starts working, it drives the top column 21 to move upward. During the upward movement of the top column 21, its top comes into contact with the corresponding wire mesh 17 and applies pressure. This design effectively lifts and loosens large particles on the surface of the wire mesh 17 under the continuous action of the top column 21, thereby significantly reducing the accumulation and clogging of large particles on the surface of the wire mesh 17.

[0040] In an optional embodiment, a water level sensor 22 is fixedly installed on one side of the sewage storage tank 15. The water level sensor 22 is used to control the extension and retraction of the hydraulic telescopic column 20.

[0041] It should be noted that when the filter becomes clogged, the liquid level in the wastewater storage tank 15 will gradually rise due to the obstruction of the water flow channel. As the duration of the blockage increases, the water level in the tank will show a significant upward trend. When the water level rises to the preset warning height, the water level sensor 22 installed inside the wastewater storage tank 15 will immediately detect this abnormality. At this time, the system will automatically trigger the working mechanism of the hydraulic telescopic column 20, putting it into emergency working mode. The entire process ensures that the wastewater treatment system can operate safely and efficiently when encountering blockage faults.

[0042] In summary, when lime water or lime blocks generated during rainfall or construction fall onto the tower crane body 12, this wastewater flows downwards along the tower body 12 and is diverted at the reinforcing ribs 24 at the bottom of the tower crane body 12, guiding the wastewater to the interior of the bottom installation position 14. Since the installation position 14 is connected to the guide channel 16, the wastewater will flow back into the wastewater storage tank 15 through the guide channel 16. Large particles such as lime blocks will remain in the wastewater as it flows through the installation position 14, the guide channel 16, and the wastewater storage tank 15. When the wastewater passes through the wastewater storage tank 15, it first passes through the filtration section and then falls into the sedimentation section. During the filtration process, the wire mesh 17 intercepts large cement blocks and other large particles flowing with the cement water, effectively preventing these large particles from directly entering subsequent stages and causing blockages. Subsequently, the wastewater is filtered again through the filter plate 18 to further remove any remaining large particles. After these two filtration processes, the solid particles in the wastewater are fully removed, and the filtered wastewater enters the sedimentation section for sedimentation.

[0043] Inside the sedimentation section, fine cement particles in the cement water gradually settle under gravity, eventually settling at the bottom of the base 11. This sedimentation process not only purifies the wastewater but also continuously increases the weight of the base 11 through the accumulation of cement deposits, thereby improving the stability of the entire system. At the same time, it avoids cement waste and achieves full utilization of cement.

[0044] After the wastewater settles in the sedimentation section, the water flows through the water pipe into the interior of the collection tank 13, facilitating water intake for later construction work. The one-way valve 23 prevents excessive water in the collection tank 13 from flowing back into the sedimentation section.

[0045] When the filter becomes clogged, the liquid level in the wastewater storage tank 15 will gradually rise due to the obstruction of the water flow channel. As the duration of the blockage increases, the water level in the tank will show a significant upward trend. When the water level rises to a preset warning height, the water level sensor 22 installed inside the wastewater storage tank 15 will immediately detect this abnormality. At this time, the system will automatically trigger the working mechanism of the hydraulic telescopic column 20, putting it into emergency working mode. The entire process ensures that the wastewater treatment system can operate safely and efficiently when encountering blockage failures.

[0046] A self-draining tower crane foundation structure, through the setting of reinforcing ribs 24 and guide channels 16, allows rainwater, cement water, cement blocks and other large particulate wastewater to flow from the tower body 12 into the interior of the wastewater storage bin 15, which is used to store various types of wastewater, prevent wastewater from corroding the tower crane body 12, achieve the function of self-draining, and also extend the service life of the tower crane equipment.

[0047] A self-draining tower crane foundation structure, through the setting of a sewage storage tank 15 and a water collection tank 13, allows sewage to pass through a filtration section to intercept cement blocks and other large particles while inside the sewage storage tank 15. The filtered sewage then enters a sedimentation section for sedimentation, causing fine cement particles in the sewage to gradually settle under gravity and eventually deposit at the bottom of the base 11, continuously increasing the weight of the base 11 and thus improving the stability of the entire system. At the same time, it can also avoid cement waste. The water treated by the sewage storage tank 15 flows through a water pipe into the water collection tank 13, making it convenient for workers to draw water during later construction.

[0048] A self-draining tower crane foundation structure, through the arrangement of hydraulic telescopic columns 20 and top columns 21, allows the top column 21 to move upward when the hydraulic telescopic columns 20 are activated. During the ascent of the top column 21, its top comes into contact with the corresponding wire mesh 17 and applies pressure. This design effectively lifts and loosens large particles on the surface of the wire mesh 17 under the continuous action of the top column 21, thereby significantly reducing the accumulation and clogging of large particles on the surface of the wire mesh 17 and improving the service life of the device.
