Description

Technical Field

[0001] This invention relates to the field of deep foundation pit support technology, and in particular to a deep foundation pit support system in a limited space. Background Technology

[0002] Deep foundation pit support refers to the measures taken to support, reinforce, and protect the sidewalls and surrounding environment of a deep foundation pit in order to ensure the safety of underground structure construction and the surrounding environment. During the excavation of a deep foundation pit, internal forces and displacements in the support structure within the pit, as well as deformation of the soil inside and outside the pit, will occur. This not only endangers the deep foundation pit itself but also the surrounding buildings, easily leading to major accidents and causing huge economic losses and casualties. Currently, deep foundation pit support systems generally do not have supporting safety monitoring agencies, making it impossible to monitor the real-time status of the deep foundation pit support system, and the safety of construction personnel cannot be guaranteed.

[0003] Existing deep foundation pit support systems, such as the one described in application number 201510487576.X, involve an ultra-deep foundation pit support system. This system is characterized by comprising a single-row, three-axis deep mixing pile water-stop curtain, bored piles, and steel columns. The single-row, three-axis deep mixing pile water-stop curtain is installed below the natural ground level along the perimeter of the foundation pit. Multiple bored piles are sequentially and intermittently installed within the foundation pit inside the single-row, three-axis deep mixing pile water-stop curtain. Multiple steel columns are installed within the foundation pit inside the bored piles. The tops of the multiple bored piles are sequentially connected by reinforced concrete capping beams. Reinforced concrete walers are installed along the perimeter of the foundation pit at locations other than the height of each underground floor slab. However, in the above technology, because the support system is fixed, there are differences in the hardness of the soil and rock within the pit, making it difficult to achieve uniform positioning during installation. Therefore, we propose a deep foundation pit support system for limited sites to solve the above problems. Summary of the Invention

[0004] To address the aforementioned problems, this invention proposes a deep foundation pit support system for limited sites. This system primarily utilizes a fixed inter-support mechanism installed at the bottom of a limiting component. An adjustment mechanism located on the top plate of the limiting component, along with an electric winding drum, steel cable, lifting base, output motor, rotating arm, searchlight, camera, hydraulic telescopic arm, and drive gear, moves the user and equipment to the processing location. The output power of the hydraulic telescopic arm and drive gear engages the drive gear with the driven gear, causing the threaded strip and threaded chamber to rotate under the meshing transmission of each set of driven and drive gears, thus lifting the sliding block to a suitable position. Due to the slotted structure of the initial four-part arc groove plate, the insertion height can be freely selected according to the different textures of the soil and rock, improving the flexibility of equipment fixation.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A deep foundation pit support system in a limited space includes a limiting component and an adjustment mechanism. The bottom end of the limiting component is provided with a support mechanism that is fixedly inserted, and the upper end of the limiting component is provided with an adjustment mechanism that is bolted and fixed.

[0007] As a further technical solution, the limiting component includes an end plate, a fixing sleeve, a lifting ring, an end bolt, a plug pin, and a semi-circular shell sleeve, with a fixing sleeve for installing the lifting ring provided on the top side of the end plate.

[0008] As a further technical solution, a plug pin for connecting the output end of the end bolt is provided at the lower end of one end of the end plate, and a semi-circular shell is provided at the inner end of the end plate.

[0009] As a further technical solution, the support mechanism includes a fixed hanging rod, a primary quarter-arc groove plate, a hinged base, a movable sleeve, a spline seat, a first threaded sleeve, an upper insert rod, a sliding strip, a sliding block, a threaded strip, a threaded chamber, a fixed shaft seat, a driven gear, an output rod, an output screw, a sleeve block, a top housing, a meshing gear set, a threaded shell, a lower insert rod, a connecting rod, an assembly plate, an additional quarter-arc groove plate, a bottom fitting block, and a bottom insert rod assembly. The primary quarter-arc groove plate is fixedly inserted into the bottom side of the semi-arc shell sleeve by the fixed hanging rod. The bottom side of the primary quarter-arc groove plate is bolted to a connecting rod by the assembly plate. The bottom side of the assembly plate is provided with an additional quarter-arc groove plate. The bottom end of the additional quarter-arc groove plate is bolted to a bottom insert rod assembly by the bottom fitting block.

[0010] As a further technical solution, the upper inner side of the initial four-segment arc groove plate is movably connected to a movable sleeve bar via a hinged base, and one end of the movable sleeve bar is provided with a spline seat, the other end of the movable sleeve bar is provided with a first threaded sleeve, and one end of the first threaded sleeve is provided with an upper insert bar.

[0011] As a further technical solution, a sliding block is slidably connected to the inner groove of the initial four-part arc groove plate by a sliding strip, and a threaded strip is provided on the bottom side of the sliding block. A threaded compartment is provided below the threaded strip, and a driven gear output end is connected to the fixed shaft seat through the threaded compartment.

[0012] As a further technical solution, an output rod is provided on the inner bottom side of the sliding block, and a sleeve block is threadedly connected to the inner side of the sliding block through an output screw. A top housing is provided on the top side of the sliding block, and a meshing gear set is provided inside the top housing. A lower insert rod is threadedly connected to one end of the top housing through a threaded shell.

[0013] As a further technical solution, the adjustment mechanism includes a bolt base block, a lifting frame, a crossbar, an end ring hole seat, an electric winding drum, a steel cable, a lifting base, an output motor, a rotating arm, a searchlight, a camera, a hydraulic telescopic arm, and a drive gear. The lifting frame is bolted to the upper end of the end crossbar via the bolt base block. A crossbar is provided on the top side of the lifting frame, and end ring hole seats are provided at both ends of the crossbar. The output end of the crossbar is wound with a steel cable via an electric winding drum.

[0014] As a further technical solution, a lifting base is provided on the bottom side of the steel cable, and a rotating arm connected to the output end of the output motor is provided below the lifting base. One end of the rotating arm is provided with a hydraulic telescopic arm whose output end is connected to the drive gear.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The invention mainly utilizes an interlocking mechanism fixedly installed at the bottom of the limiting component. An adjustment mechanism is set on the top plate of the limiting component. Using an electric winding drum, steel cable, lifting base, output motor, rotating arm, searchlight, camera, hydraulic telescopic arm, and drive gear, the user and equipment are moved to the processing location. The output power of the hydraulic telescopic arm and drive gear meshes the drive gear with the driven gear. Under the meshing transmission of each set of driven gears and drive gears, the spiral of the threaded strip and threaded chamber is rotated, raising the sliding block to a suitable position. Since the initial four-part arc groove plate has a slotted structure, it can effectively achieve the selection of the insertion height according to the different textures of the soil and rock, improving the fixed flexibility of the equipment.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-6 In this embodiment of the invention, a deep foundation pit support system in a limited space includes a limiting component 1 and an adjustment mechanism 3.

[0029] In an embodiment of the present invention, when in use, the limiting component 1 is hoisted by a crane using the hoisting ring 103 on the top side of the fixing sleeve 102, and the equipment is placed at the processing location.

[0030] A plug pin 105 for connecting the output end of the end bolt 104 is provided at the lower end of one end of the end plate 101, and a semi-arc sleeve 106 is provided at the inner end of the end plate 101.

[0031] In an embodiment of the present invention, after the equipment is placed at the processing location, the output end is driven to run by the end bolt 104, and the end plate 101 is fixed by the plug pin 105, so that the semi-circular shell 106 at the inner end of the end plate 101 can achieve the effect of assembly.

[0032] Support mechanism 2 includes a fixed hanging rod 201, a primary four-part arc groove plate 202, a hinged base 203, a movable sleeve 204, a spline seat 205, a first threaded sleeve 206, an upper insert rod 207, a sliding bar 208, a sliding block 209, a threaded bar 2010, a threaded chamber 2011, a fixed shaft seat 2012, a driven gear 2013, an output rod 2014, an output screw 2015, a sleeve block 2016, a top housing 2017, a meshing gear set 2018, a threaded shell 2019, and a lower insert rod 2020. The assembly includes a connecting rod 2021, an assembly plate 2022, a quarter-slotted plate 2023, a bottom mounting block 2024, and a bottom insert rod assembly 2025. The initial quarter-slotted plate 202 is fixedly inserted into the bottom side of the semi-arc shell 106 by a fixing rod 201. The bottom side of the initial quarter-slotted plate 202 is bolted to the connecting rod 2021 through the assembly plate 2022. The bottom side of the assembly plate 2022 is provided with a quarter-slotted plate 2023. The bottom end of the quarter-slotted plate 2023 is bolted to the bottom insert rod assembly 2025 through the bottom mounting block 2024.

[0033] In an embodiment of the present invention, after the adjustment mechanism 3 is assembled, the electric winding drum 305 outputs power to drive the output end to run, so that the steel cable 306 hoisting device hoists the initial four-part arc groove plate 202 on the bottom side of the fixed hoisting rod 201, and the fixed hoisting rod 201 fixes the initial four-part arc groove plate 202 on the bottom side of the fixed hoisting rod 201, and the assembly plate 2022 assembles the connecting rod 2021 to the initial four-part arc groove plate 2023, and the bottom mounting block 2024 and the bottom insertion rod group 2025 are installed on the bottom side of the bottom of the bottom of the bottom four-part arc groove plate 2023 and inserted into the processing location.

[0034] The upper inner side of the first four-segment arc groove plate 202 is movably connected to a movable sleeve 204 via a hinged base 203. One end of the movable sleeve 204 is provided with a spline seat 205, and the other end of the movable sleeve 204 is provided with a first threaded sleeve 206. One end of the first threaded sleeve 206 is provided with an upper insert rod 207.

[0035] In an embodiment of the present invention, when the adjustment mechanism 3 drives the equipment to a suitable depth, the user uses the movable sleeve 204 to adjust the angle of the hinge base 203. After the angle is adjusted, the spline seat 205 outputs power to drive the output end to run, and the first threaded sleeve 206 spirals so that the upper insertion rod 207 is inserted into the inside of the tunnel.

[0036] The inner groove of the first four-segment arc groove plate 202 is slidably connected to a sliding block 209 via a sliding strip 208, and a threaded strip 2010 is provided on the bottom side of the sliding block 209. A threaded chamber 2011 is provided below the threaded strip 2010, and the output end of the driven gear 2013 is connected to the fixed shaft seat 2012 through the bottom of the threaded chamber 2011.

[0037] In an embodiment of the present invention, the output motor 308 then outputs power to drive the output end to run, thereby moving the rotating arm 309 to a suitable processing position. After the hydraulic telescopic arm 3012 outputs power to drive the output end to run, the driving gear 3013 meshes with the driven gear 2013. The driving gear 3013 rotates and meshes with the driven gear 2013, thereby driving the fixed shaft seat 2012 to output power to drive the threaded chamber 2011 and the threaded strip 2010, causing the sliding block 209 to run to a suitable height under the action of the sliding strip 208.

[0038] An output rod 2014 is provided on the inner bottom side of the sliding block 209, and a sleeve block 2016 is threadedly connected to the inner side of the sliding block 209 through an output screw 2015. A top housing 2017 is provided on the top side of the sliding block 209, and a meshing gear set 2018 is provided inside the top housing 2017. A lower insertion rod 2020 is threadedly connected to one end of the top housing 2017 through a threaded shell 2019.

[0039] In an embodiment of the present invention, after the sliding block 209 reaches a suitable height, the output screw 2015 outputs power to drive the output end to run, so that the sleeve block 2016 is sleeved on the output rod 2014. After the threaded chamber 2011 and the threaded strip 2010 run, the output rod 2014 and the sleeve block 2016 run coaxially. In this way, the output power of the output rod 2014 drives the meshing gear set 2018 on the top housing 2017 to mesh and drive. Through the meshing and driving of the meshing gear set 2018, the lower insertion rod 2020 at one end of the threaded shell 2019 is inserted into the inner edge of the tunnel, thereby achieving a fixing effect. After installation, the user is evacuated using the adjustment mechanism 3.

[0040] The adjustment mechanism 3 includes a bolt base 301, a lifting frame 302, a crossbar 303, an end ring hole seat 304, an electric winding drum 305, a steel cable 306, a lifting base 307, an output motor 308, a rotating arm 309, a searchlight 3010, a camera 3011, a hydraulic telescopic arm 3012, and a drive gear 3013. The lifting frame 302 is bolted to the upper end of the end of the end crossbar 101 via the bolt base 301. A crossbar 303 is provided on the top side of the lifting frame 302, and end ring hole seats 304 are provided at both ends of the crossbar 303. The output end of the crossbar 303 is wound with a steel cable 306 via the electric winding drum 305.

[0041] In an embodiment of the present invention, after the end plate 101 is installed, the lifting frame 302 is fixed above the end of the end plate 101 using bolt base 301. Then, the end ring hole seat 304 is used to suspend the crossbar 303 on the top side of the lifting frame 302, and the electric winding drum 305 is wound around the steel cable 306 for processing.

[0042] A lifting base 307 is provided on the bottom side of the steel cable 306. A rotating arm 309 connected to the output end of the output motor 308 is provided below the lifting base 307. A hydraulic telescopic arm 3012 whose output end is connected to the drive gear 3013 is provided at one end of the rotating arm 309.

[0043] In an embodiment of the present invention, when it is needed for use, the output end of the crossbar 303 outputs power to drive the output end to run, and the output end of the crossbar 303 drives the electric winding drum 305 to perform winding processing. After the electric winding drum 305 rotates, the steel cable 306 drives the lifting base 307 to descend to a suitable processing location, and drives the user to a suitable position. With the cooperation of the searchlight 3010 and the camera 3011, the effect of observation and lighting of the inside of the tunnel is achieved.

[0044] The working principle of this invention is as follows: In use, the limiting component 1 is hoisted using a crane via the hoisting ring 103 on the top side of the fixed sleeve 102, and the equipment is placed at the processing location. After the equipment is placed at the processing location, the output end is driven by the output bolt 104, and then the end plate 101 is fixed by the plug pin 105. This allows the semi-circular shell 106 at the inner end of the end plate 101 to achieve the assembly effect. After the end plate 101 is installed, the lifting frame 302 is fixed above the end of the end plate 101 using the bolt base block 301. Then, the lifting crossbar 303 is hoisted onto the top side of the lifting frame 302 using the end ring hole seat 304, and the electric winding drum 305 is wound around the steel cable 306 for later use. The function of the machine is as follows: when needed, the output end of the crossbar 303 outputs power to drive the output end, which in turn drives the electric winding drum 305 to perform winding processing. The rotation of the electric winding drum 305 causes the steel cable 306 to drive the lifting base 307 to descend to a suitable processing location, and also moves the user to a suitable position. With the cooperation of the searchlight 3010 and the camera 3011, the interior of the tunnel is illuminated. After the adjustment mechanism 3 is assembled, the electric winding drum 305 outputs power to drive the output end, causing the steel cable 306 to be hoisted by the hoisting equipment onto the bottom side of the fixed lifting rod 201, and the fixed lifting rod 201... 1. The initial four-part arc groove plate 202 is fixedly hoisted onto the bottom side of the fixed hoisting rod 201, and the assembly plate 2022 assembles the connecting rod 2021 with the additional four-part arc groove plate 2023 and the initial four-part arc groove plate 202. The bottom assembly block 2024 and the bottom insertion rod assembly 2025 are set on the bottom side of the additional four-part arc groove plate 2023 and inserted into the processing location. When the adjusting mechanism 3 drives the equipment to a suitable depth, the user uses the movable sleeve rod 204 to adjust the angle of the hinge base 203. After the angle is adjusted, the spline seat 205 outputs power to drive the output end to run. After the first threaded sleeve 206 is spirally run, the upper insertion rod 207 is inserted into the inside of the tunnel. Then, the output motor 308 outputs power to drive the... After the output end starts operating, the rotating arm 309 is moved to a suitable processing position. The hydraulic telescopic arm 3012 then outputs power to drive the output end, causing the driving gear 3013 to mesh with the driven gear 2013. The rotating driving gear 3013 then meshes with the driven gear 2013, causing the fixed shaft seat 2012 to output power to drive the threaded chamber 2011 and threaded strip 2010. This causes the sliding block 209 to move to a suitable height under the action of the sliding strip 208. Once the sliding block 209 reaches the suitable height, the output screw 2015 outputs power to drive the output end, causing the sleeve block 2016 to engage with the output rod 2014. After the threaded chamber 2011 and threaded strip 2010 have moved...The output rod 2014 and the mounting block 2016 move coaxially, causing the output power of the output rod 2014 to drive the meshing gear set 2018 on the top housing 2017. This meshing gear set 2018 then drives the lower insertion rod 2020 at one end of the threaded housing 2019 to insert into the inner edge of the tunnel, thus achieving a fixed position. After installation, the user can be evacuated using the adjustment mechanism 3.
