Description

Technical Field

[0001] This utility model belongs to the technical field of deep foundation pit support replacement device, specifically relating to a rapid support replacement construction device for deep foundation pits. Background Technology

[0002] The replacement of internal supports in deep foundation pits is a crucial step in ensuring structural safety and smooth construction in deep foundation pit engineering. During the construction of deep foundation pits, as earthwork excavation and underground structure construction progress, it is necessary to adjust and replace the support system within the foundation pit to adapt to the stress requirements of different construction stages. This process is called the replacement of internal supports in deep foundation pits. It is essential to ensure the stability of the foundation pit during construction, control the deformation of the surrounding soil, protect surrounding buildings, underground pipelines, and other environmental factors from the impact of construction, and create a safe working space for the construction of underground structures.

[0003] Traditional deep foundation pit internal support replacement construction devices require manual operation or the use of some cumbersome mechanical devices to replace the supports. The operation process is complicated and time-consuming, resulting in a slow overall construction progress. Furthermore, due to the slow support replacement process, the foundation pit remains in an unstable state for a long time, which increases the safety risks such as foundation pit collapse and surrounding ground settlement, posing a significant threat to the safety of construction personnel and the surrounding environment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] like Figures 1 to 3 As shown;

[0025] A rapid support replacement construction device for deep foundation pits includes a base plate 1, a support plate 2 disposed on the outer side of the end of the base plate 1, and a support mechanism. The support mechanism is used to lift the support plate 2 to facilitate rapid support operations. The support mechanism includes a first lifting component 3 and a second lifting component 4. The first lifting component 3 includes a first mounting plate 301, which is slidably connected to the upper surface of the base plate 1. A sleeve 307 is fixedly connected to one side of the first mounting plate 301, and a sliding rod 302 is slidably connected to the inner side of the sleeve 307. A connecting plate 303 is fixedly connected to the outer side of one end of the sliding rod 302, and a rotating component is rotatably connected to the inner side of the top of the first mounting plate 301. A second gear 306 is fixedly connected to the outer sides of both ends of a rotating shaft 304, and a first gear 305 is fixedly connected to the outer side of the middle part of the rotating shaft 304. An arc-shaped through groove is provided on one side of a sleeve 307. The second gear 306 contacts one side of a slide rod 302 through the arc-shaped through groove of the sleeve 307. The upper surface of a connecting plate 303 is fixedly connected to the lower surface of a support plate 2. A toothed plate 308 is slidably connected to the upper surface of a first mounting plate 301. One side of the toothed plate 308 is meshed with the first gear 305. A telescopic cylinder 309 is mounted on the upper surface of the first mounting plate 301. One outer side of the telescopic cylinder 309 is fixedly connected to one outer side of the toothed plate 308.

[0026] In this implementation scheme: When using the device, the user can move it to the bottom of the workpiece that needs to be replaced. At this time, the user can activate the telescopic cylinder 309. The telescopic cylinder 309 drives the toothed plate 308 to slide on the upper surface of the first mounting plate 301. Then, the toothed plate 308 drives the first gear 305 to rotate. While the first gear 305 is rotating, it drives the second gear 306 to rotate through the rotating shaft 304. When the rotating shaft 304 rotates, it will contact the tooth structure on one side of the slide rod 302. Then, it can drive the slide rod 302 to rise vertically inside the sleeve 307. The workpiece can be lifted by the lifting of the connecting plate 303 and the support plate 2. Then, the lifting component 3 and the workpiece can be pulled out for replacement through the slide rail 5. The connection of the rotating shaft 304 can ensure that the two slide rods 302 rise synchronously, thus ensuring the horizontal state of the connecting plate 303. Example

[0027] like Figures 4 to 6 As shown;

[0028] The second lifting assembly 4 includes a second mounting plate 401, which is slidably connected to the upper surface of the base plate 1. A motor 402 is mounted on the upper surface of the second mounting plate 401. A threaded rod 403 is fixedly connected to the outer side of the main shaft of the motor 402. A sliding block 404 is slidably connected to the upper surface of the second mounting plate 401. The outer side of the threaded rod 403 is threadedly connected to the inner side of the end of the sliding block 404. The outer sides of both ends of the sliding block 404 are rotatably connected to a first support arm 405. The inner side of the middle part of the first support arm 405 is rotatably connected to a second support arm 406. The outer side of the end of the second support arm 406 is rotatably connected to the inner side of the end of the second mounting plate 401. The outer side of the end of the first support arm 405 is rotatably connected to the lower surface of the support plate 2. Multiple sets of protrusions are evenly arranged on the upper surface of the base plate 1. A slide rail 5 is mounted on the upper surface of the base plate 1. The first lifting assembly 3 and the second lifting assembly 4 can be slidably connected to the base plate 1 through the slide rail 5.

[0029] In this implementation scheme: the user can start the motor 402, which in turn drives the threaded rod 403 to rotate. As the threaded rod 403 rotates, it drives the sliding block 404 on its outer side to move. As the sliding block 404 moves, it moves against the bottom of the first support arm 405. At the same time, with the support of the second support arm 406, the support plate 2 on the outer side of the end of the first support arm 405 can be driven to rise vertically. Meanwhile, the protrusion on the upper surface of the support plate 2 can increase the friction with the workpiece. Starting the motor 402 on one side can tilt the workpiece on the upper surface of the support plate 2, which is suitable for various processing scenarios.

[0030] Working principle: When using this device, the user can move it to the bottom of the workpiece that needs to be supported. At this time, the user can activate the telescopic cylinder 309. The telescopic cylinder 309 drives the toothed plate 308 to slide on the upper surface of the first mounting plate 301. In turn, the toothed plate 308 drives the first gear 305 to rotate. While the first gear 305 is rotating, it drives the second gear 306 to rotate through the rotating shaft 304. When the rotating shaft 304 rotates, it will contact the tooth structure on one side of the slide rod 302, thereby driving the slide rod 302 to move inside the sleeve 307. Vertically rising, the workpiece can be lifted by the connecting plate 303 and the support plate 2, and then the lifting assembly 3 and the workpiece can be pulled out for replacement via the slide rail 5. The connection of the rotating shaft 304 ensures that the two slide rods 302 rise synchronously, thus ensuring the horizontal state of the connecting plate 303. The lifting assembly 4 includes a second mounting plate 401, which is slidably connected to the upper surface of the base plate 1. A motor 402 is mounted on the upper surface of the second mounting plate 401, and a threaded rod 403 is fixedly connected to the outside of the main shaft of the motor 402. The upper surface of the second mounting plate 401 is slidably connected to... The outer side of the sliding block 404 and the inner side of the threaded rod 403 are threadedly connected to the inner side of the end of the sliding block 404. The outer sides of both ends of the sliding block 404 are rotatably connected to the first support arm 405. The inner side of the middle part of the first support arm 405 is rotatably connected to the second support arm 406. The outer side of the end of the second support arm 406 is rotatably connected to the inner side of the end of the second mounting plate 401. The outer side of the end of the first support arm 405 is rotatably connected to the lower surface of the support plate 2. The upper surface of the base plate 1 is evenly provided with multiple sets of protrusions. The upper surface of the base plate 1 is equipped with a slide rail 5. The lifting assembly 1 3 and the lifting assembly 2 4 can pass through the slide rail. 5 is slidably connected to the base plate 1, enabling rapid lifting and quick workpiece replacement through the support mechanism. This effectively shortens the time for foundation pit support conversion, significantly improves construction efficiency, accelerates project progress, reduces foundation pit exposure time, and significantly reduces safety risks such as collapse and deformation caused by prolonged exposure. It ensures construction safety, avoids support stress fluctuations caused by slow operation in traditional support replacement methods, stably controls foundation pit deformation, and improves construction quality. At the same time, it reduces the intensity and difficulty of frequent manual operations, reduces manpower input, saves construction costs, and provides an efficient, safe, and economical solution for deep foundation pit engineering.
