Description

Technical Field

[0001] This utility model relates to the field of steel pipe pile group support technology, specifically a steel pipe pile group support device. Background Technology

[0002] Steel pipe pile group support device is an important support structure used in civil engineering and building engineering, especially in deep foundation pit engineering. This device is mainly composed of multiple steel pipe piles, which are driven into the ground in a certain arrangement (such as row and column, plum blossom pile, etc.) to form an integrated support system to resist the pressure from the surrounding soil and ensure the safety and stability of the foundation pit excavation process.

[0003] To improve the support effect of support devices, support plates and steel pipe piles are usually combined to support buildings. However, most existing support plates and steel pipe piles are fixed assemblies, which are inconvenient to adjust according to usage. Fixed assembly limits the adaptability of the support system, making it difficult to adjust according to specific geological conditions or site requirements. This may lead to the need to design different customized solutions for different projects, increasing preparation time and costs. Utility Model Content

An inclined fixed sleeve is rotatably connected to one side of the two lifting threaded sleeves inside each steel pipe pile sleeve. The two fixed sleeves extend to the outside of the steel pipe pile sleeve and are slidably connected to the inner wall of the guide groove. A telescopic rod is slidably connected inside each fixed sleeve. The end of the telescopic rod away from the fixed sleeve extends to the outside and is rotatably connected to the rear surface of the No. 2 support plate. The telescopic rod extends to the inside of the No. 1 support plate and is slidably connected to the inner wall of the vertical groove.

[0007] As a preferred embodiment of the steel pipe pile group support device of this utility model, each of the fixed sleeves is provided with a spring inside, one bottom end of the spring is fixedly connected to one side of the inner wall of the fixed sleeve, and the other end of the spring is fixedly connected to one bottom end of the telescopic rod.

[0008] As a preferred embodiment of the steel pipe pile group support device of this utility model, each of the two steel pipe pile sleeves is rotatably connected to a bidirectional threaded rod at its center, and a worm gear is fixedly sleeved on the center surface of each of the two bidirectional threaded rods. A worm is meshed with one side of each of the two worm gears, and the two worms are respectively rotatably arranged inside the two steel pipe pile sleeves.

[0009] In a preferred embodiment of the steel pipe pile group support device of this utility model, one end of each of the two worm gears is rotatably connected to the inner wall of the two steel pipe pile sleeves, and the other end of each of the two worm gears extends to the outside of the two steel pipe pile sleeves and is rotatably connected to the two steel pipe pile sleeves. Each of the two worm gears has a fastening knob fixedly connected to one end located outside the two steel pipe pile sleeves.

[0010] As a preferred embodiment of the steel pipe pile group support device of this utility model, the upper and lower surfaces of the two bidirectional threaded rods are threadedly connected with lifting threaded sleeves, and the interior of the two steel pipe pile sleeves is fixedly connected with lifting limit rods. The top and bottom of each lifting limit rod are fixedly connected to the top and bottom of the inner wall of each steel pipe pile sleeve, respectively. The upper and lower lifting threaded sleeves inside each steel pipe pile sleeve are slidably connected to the lifting limit rods.

[0011] As a preferred embodiment of the steel pipe pile group support device of this utility model, a first triangular reinforcing block is fixedly connected between the two steel pipe pile sleeves and the right side of the outer wall of the first support plate, a connecting plate is fixedly connected between the two steel pipe pile sleeves, and a plurality of second triangular reinforcing blocks are fixedly connected between the connecting plate and the right side of the outer wall of the first support plate at equal intervals.

[0012] As a preferred embodiment of the steel pipe pile group support device of this utility model, the two No. 1 triangular reinforcing blocks and the multiple No. 2 triangular reinforcing blocks are all located on the same horizontal line, and a rubber pad is fixedly connected to the left side of the outer wall of the No. 1 support plate.

[0013] As a preferred embodiment of the steel pipe pile group support device of this utility model, the two No. 2 support plates are rectangular structures with openings on the left and right sides.

The telescopic ends of the multiple bidirectional electric push rods are fixedly connected to the two No. 3 support plates on the side close to each other.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model directly controls the lateral position of the No. 3 support plate through the telescopic movement of bidirectional electric actuators. When the support width needs to be adjusted, the control system can instruct the bidirectional electric actuators to extend or shorten, causing the No. 3 support plate to move outward or inward, thereby changing the total width of the support system. The use of bidirectional electric actuators automates width adjustment, reducing the need for manual intervention. Construction personnel can precisely control the movement of each bidirectional electric actuator through remote control or preset programs, improving work efficiency and accuracy. The introduction of the No. 3 support plate provides additional lateral support, especially under conditions of high lateral pressure. Multiple No. 3 support plates work together to enhance the lateral load-bearing capacity of the entire support system, ensuring structural stability. Because the No. 3 support plate can be flexibly adjusted, this design is particularly suitable for construction sites with complex or variable geological conditions. It allows for rapid adjustment of the support width according to the actual geological conditions, ensuring optimal support effectiveness.

[0016] 2. When the tightening knob of this utility model is rotated, the worm gear rotates accordingly, and transmits the rotational force to the double-threaded rod through the worm wheel. The rotation of the double-threaded rod causes the two lifting threaded sleeves connected to it to move up and down synchronously. The lifting threaded sleeve slides along the lifting limit rod, ensuring its precise and stable movement in the vertical direction and avoiding lateral displacement caused by thread rotation. The existence of the lifting limit rod provides a stable guide path for the lifting threaded sleeve, ensuring that it can only move in the vertical direction and will not rotate or tilt. The fixed sleeve changes height as the lifting threaded sleeve moves, thereby adjusting the height of the entire support system. The telescopic rod slides in the fixed sleeve and is maintained with a certain preload by the spring, ensuring that it is always in the optimal working state. Attached Figure Description

[0023] Please see Figures 1-5 A steel pipe pile group support device includes a first support plate 1, which is a rectangular structure with openings at the top and bottom. Second support plates 2 are slidably connected to the upper and lower parts of the first support plate 1. The two second support plates 2 extend to the outside of the first support plate 1 on opposite sides and are slidably connected to the top and bottom of the first support plate 1, respectively. Vertical grooves 101 are correspondingly positioned at the upper and lower ends of the right side of the first support plate 1.

[0024] Furthermore, steel pipe pile sleeves 3 are provided at both the front and rear ends of the right side of the No. 1 support plate 1. Guide grooves 301 are symmetrically opened at the upper and lower positions on the surface of the two steel pipe pile sleeves 3 near the No. 1 support plate 1. Lifting threaded sleeves 8 are slidably connected at the upper and lower positions inside the two steel pipe pile sleeves 3. An inclined fixed sleeve 10 is rotatably connected to one side of the two upper and lower lifting threaded sleeves 8 inside each steel pipe pile sleeve 3. The two fixed sleeves 10 extend to the outside of the steel pipe pile sleeve 3 and are slidably connected to the inner wall of the guide groove 301. A telescopic rod 11 is slidably connected inside each fixed sleeve 10. The end of the telescopic rod 11 away from the fixed sleeve 10 extends to its outside and is rotatably connected to the rear surface of the No. 2 support plate 2. The telescopic rod 11 extends to the inside of the No. 1 support plate 1 and is slidably connected to the inner wall of the vertical groove 101.

[0025] Support plate 1, as the primary support structure, provides horizontal support force and provides a sliding track for support plate 2. Support plate 1 has openings at its top and bottom, allowing support plate 2 to slide up and down within it. Support plate 2 assists support plate 1 in providing additional support, and its movement adjusts the support height. Support plate 2 and support plate 1 form a sliding connection, allowing it to extend or retract as needed.

[0026] Vertical grooves 101 are located at the front and rear ends of the right side of the No. 1 support plate 1, and are used to guide the movement of the telescopic rod 11 to ensure that it slides in the correct position. The steel pipe pile sleeve 3 accommodates and fixes the steel pipe pile, providing vertical support, and also serves as an installation platform for the lifting threaded sleeve 8 and the fixing sleeve 10. The guide groove 301 provides a sliding path for the fixing sleeve 10, ensuring that its tilt angle is adjustable.

[0027] The lifting threaded sleeve 8 controls its vertical movement by rotation, thereby adjusting the height of the fixed sleeve 10 and slidingly connecting with the steel pipe pile sleeve 3, enabling precise height adjustment. The fixed sleeve 10 is tilted and slidably connected with the telescopic rod 11, transmitting the movement within the steel pipe pile sleeve 3 to the telescopic rod 11, ensuring a stable connection between the second support plate 2 and the steel pipe pile sleeve 3. The telescopic rod 11 connects the second support plate 2 and the fixed sleeve 10, serving to transmit force, and its telescopic characteristics allow for adjustment of the support area.

[0028] Furthermore, each fixed sleeve 10 is provided with a spring 12 inside. One bottom end of the spring 12 is fixedly connected to one side of the inner wall of the fixed sleeve 10, and the other end of the spring 12 is fixedly connected to one bottom end of the telescopic rod 11.

[0029] Spring 12 can absorb external pressure or impact, acting as a buffer. When encountering uneven ground or unexpected loads during construction, spring 12 can reduce the direct impact of these forces on the entire support system, thus protecting the structure from damage. Simultaneously, spring 12 has elastic recovery capabilities, allowing it to rebound after being compressed by external forces. If the telescopic rod 11 shifts due to ground settlement or other reasons, spring 12 can help it return to its original position, ensuring the stability of the support system.

[0030] Furthermore, each of the two steel pipe pile sleeves 3 has a bidirectional threaded rod 4 rotatably connected to its center, and a worm gear 5 is fixedly fitted on the center surface of each of the two bidirectional threaded rods 4. A worm 6 is meshed with one side of each of the two worm gears 5, and the two worms 6 are rotatably installed inside the two steel pipe pile sleeves 3 respectively.

[0031] The bidirectional threaded rod 4 is used to simultaneously drive the relative movement of the two lifting threaded sleeves 8, achieving symmetrical height adjustment. When the bidirectional threaded rod 4 rotates, it can synchronously drive the two lifting threaded sleeves 8 to move up and down. The worm gear 5, as an intermediate transmission element, converts the rotational motion of the worm 6 into the rotational motion of the bidirectional threaded rod 4. The worm gear 5 is fixedly sleeved on the center surface of the bidirectional threaded rod 4 to ensure that the two rotate synchronously. The worm gear 5 meshes with the worm 6, providing precise motion transmission.

[0032] Furthermore, one end of each of the two worm gears 6 is rotatably connected to the inner wall of each of the two steel pipe pile sleeves 3, and the other end of each of the two worm gears 6 extends to the outside of each of the two steel pipe pile sleeves 3 and is rotatably connected to each of the two steel pipe pile sleeves 3. Each of the two worm gears 6 located outside the two steel pipe pile sleeves 3 is fixedly connected to a fastening knob 7.

[0033] The worm 6 transmits the externally applied rotational force to the bidirectional threaded rod 4 through meshing with the worm wheel 5, thereby controlling the up and down movement of the lifting threaded sleeve 8. The fastening knob 7 provides a convenient operating interface, allowing construction personnel to easily adjust the height. Rotating the fastening knob 7 can directly affect the rotation of the worm 6, thereby changing the position of the lifting threaded sleeve 8.

[0034] Furthermore, the upper and lower surfaces of the two bidirectional threaded rods 4 are threaded with lifting threaded sleeves 8, and the interior of the two steel pipe pile sleeves 3 are fixedly connected with lifting limit rods 9. The top and bottom of each lifting limit rod 9 are fixedly connected to the top and bottom of the inner wall of each steel pipe pile sleeve 3, respectively. The upper and lower lifting threaded sleeves 8 inside each steel pipe pile sleeve 3 are slidably connected to the lifting limit rods 9.

[0035] The lifting threaded sleeve 8 moves up and down through a threaded connection with the bidirectional threaded rod 4, thereby adjusting the height of the fixed sleeve 10 and the telescopic rod 11. The lifting limit rod 9 provides vertical guidance and limit functions to ensure that the lifting threaded sleeve 8 moves in a straight line and prevents it from deviating or rotating during movement.

[0036] Furthermore, a first triangular reinforcing block 13 is fixedly connected between the two steel pipe pile sleeves 3 and the right side of the outer wall of the first support plate 1. A connecting plate 14 is fixedly connected between the two steel pipe pile sleeves 3. Multiple second triangular reinforcing blocks 15 are fixedly connected between the connecting plate 14 and the right side of the outer wall of the first support plate 1 at equal intervals.

[0037] Triangular reinforcing block 13 is fixedly connected between the steel pipe pile sleeve 3 and the right side of the outer wall of the No. 1 support plate 1, located on the same horizontal line. The triangular design provides additional support force to prevent deformation or loosening at the connection. Connecting plate 14 is fixedly connected between the two steel pipe pile sleeves 3, increasing lateral stability and improving the coordination of the entire support system. Triangular reinforcing blocks 15 are equidistantly arranged between the connecting plate 14 and the right side of the outer wall of the No. 1 support plate 1, located on the same horizontal line. Multiple triangular reinforcing blocks 15 work together to further strengthen the entire structure, disperse stress, and prevent excessive local stress.

[0038] Furthermore, the two No. 1 triangular reinforcing blocks 13 and the multiple No. 2 triangular reinforcing blocks 15 are all located on the same horizontal line, and a rubber pad 16 is fixedly connected to the left side of the outer wall of the No. 1 support plate 1.

[0039] Rubber pad 16 provides cushioning and anti-slip functions, protecting the No. 1 support plate 1 from direct impact. It is fixedly connected to the left side of the outer wall of the No. 1 support plate 1, and can absorb vibration and impact force, reduce noise, and increase the friction of the contact surface to increase stability.

[0040] Furthermore, the two No. 2 support plates 2 are rectangular structures with openings on the left and right sides. A center block 201 is fixedly connected to the center of the inner wall of each of the two No. 2 support plates 2. Multiple bidirectional electric push rods 202 are equidistantly arranged through the two center blocks 201 from top to bottom. No. 3 support plates 203 are provided on the left and right sides inside the two No. 2 support plates 2. The telescopic ends of the multiple bidirectional electric push rods 202 are fixedly connected to the two No. 3 support plates 203 on the side closest to each other.

[0041] The telescopic movement of the bidirectional electric actuator 202 directly controls the lateral position of the No. 3 support plate 203. When the support width needs to be adjusted, the bidirectional electric actuator 202 can be extended or shortened by the control system, causing the No. 3 support plate 203 to move outward or inward, thereby changing the total width of the support system. The use of the bidirectional electric actuator 202 automates the width adjustment, reducing the need for manual intervention. Construction personnel can precisely control the movement of each bidirectional electric actuator 202 through remote control or preset programs, improving work efficiency and accuracy. The introduction of the No. 3 support plate 203 provides additional lateral support, especially under conditions of high lateral pressure. Multiple No. 3 support plates 203 work together to enhance the lateral load-bearing capacity of the entire support system, ensuring structural stability. Because the No. 3 support plate 203 can be flexibly adjusted, this design is particularly suitable for construction sites with complex or variable geological conditions. It can quickly adjust the support width according to the actual strata conditions, ensuring optimal support effect.

[0042] When the fastening knob 7 is rotated, the worm gear 6 rotates accordingly, transmitting rotational force to the double-threaded rod 4 via the worm wheel 5. The rotation of the double-threaded rod 4 causes the two lifting threaded sleeves 8 connected to it to move up and down synchronously. The lifting threaded sleeves 8 slide along the lifting limit rod 9, ensuring their precise and smooth movement in the vertical direction and avoiding lateral displacement caused by thread rotation. The presence of the lifting limit rod 9 provides a stable guide path for the lifting threaded sleeves 8, ensuring that they can only move in the vertical direction and will not rotate or tilt. The fixed sleeve 10 changes height as the lifting threaded sleeves 8 move, thereby adjusting the height of the entire support system. The telescopic rod 11 slides within the fixed sleeve 10 and is maintained with a certain preload by the spring 12, ensuring that it is always in the optimal working state.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
