Solidified soil segment inclined supporting device having self-balancing function

Abstract

The present invention relates to the technical field of inclined supporting devices, and disclosed is a solidified soil segment inclined supporting device having a self-balancing function. The device comprises an inclined supporting rod, an adjustable end, a self-balancing base, and an auxiliary device. In the present invention, when a locking ring rotates, the locking ring simultaneously drives ramp blocks to rotate; each ramp block drives, by means of a lever assembly, a force transmission rod to slide downward; and the force transmission rod drives pin plates engaged therewith to rotate and expand, thereby increasing the contact area between the bottom of an anchor rod and solidified soil. By utilizing the lever principle, a downward force applied to the force transmission rod is increased, which facilitates the pin plates to overcome resistance from the surrounding solidified soil and expand. The provision of a plurality of anchoring assemblies allows a load transmitted from the inclined supporting rod to the self-balancing base to be automatically and uniformly distributed onto each anchoring assembly, enabling the self-balancing base to bear the load in a balanced manner and preventing local overload from causing instability of the self-balancing base. A hydraulic telescopic device and a driving motor work in conjunction with each other to drive anchor rods to be anchored into the solidified soil, and anchoring threads on the anchor rods convert rotation into linear movement, thereby accelerating the anchoring speed of the anchor rods.

Description

A self-balancing inclined support device for solidified soil sections Technical Field

[0001] This invention relates to the field of inclined bracing devices, specifically an inclined bracing device for solidified soil sections with self-balancing function. Background Technology

[0002] In the complex and critical field of deep foundation pit construction, inclined steel bracing plays a crucial role due to its unique advantages. It not only provides stable support for the foundation pit, ensuring safety and stability during construction, but also demonstrates comprehensive benefits in many aspects. Inclined steel bracing possesses extremely high adaptability and flexibility. Deep foundation pit construction often faces complex construction environments and geological conditions, while inclined steel bracing can be adjusted according to actual needs to adapt to the construction requirements of foundation pits of different depths, soil types, and terrains. This strong adaptability has led to the widespread application of inclined steel bracing in deep foundation pit construction.

[0003] However, the existing inclined bracing devices have relatively simple support points, which cannot evenly transfer the force from the upper part to the hardened soil. The single force distribution makes the support base prone to unbalanced force distribution, which can lead to support deformation or even foundation pit collapse, increasing construction risks. Moreover, the existing support system often requires a lot of manpower for installation, and its automation and intelligence levels are low, making it difficult to meet production needs. Summary of the Invention

[0004] The purpose of this invention is to provide a self-balancing inclined support device for solidified soil sections to solve the problems raised in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a self-balancing inclined support device for solidified soil sections, comprising a self-balancing base and an auxiliary device. An inclined support rod is installed on the self-balancing base, with a movable end installed at one end of the rod. The auxiliary device assists in the installation of the self-balancing base. The self-balancing base includes a base shell, a cylinder, and a bottom tray. A support spring is installed between the base shell and the bottom tray. An anchoring assembly is rotatably installed on the base shell, penetrating the bottom tray. A stabilizing ring is installed on the base shell. A main toothed ring is rotatably installed inside the base shell. A locking ring is rotatably installed inside the base shell. The cylinder is rotatably installed inside the base shell, with its output shaft rotatably connected to the locking ring. A locking assembly is slidably installed on the base shell. A lever assembly is installed inside the base shell. The main toothed ring meshes with the anchor rod assembly for transmission, and the lever assembly is rotatably connected to the anchoring assembly.

[0006] The diagonal bracing device is connected to a control console, which contains a control system used to control the entire diagonal bracing device.

[0007] Furthermore, the anchoring assembly includes an anchor rod, which meshes with a main toothed ring for transmission. The anchor rod is rotatably mounted on the base housing and passes through the bottom tray. A transmission rod is movably installed inside the anchor rod and is rotatably connected to the anchoring assembly. A return spring is installed between the transmission rod and the anchor rod. Several pins are rotatably mounted on the anchor rod, and the transmission rod meshes with the pins for transmission.

[0008] Furthermore, the anchor rod is provided with a sliding hole, the transmission rod is slidably installed in the sliding hole, the anchor rod is provided with an anchoring toothed ring, the anchoring toothed ring meshes with the main toothed ring for transmission, the anchor rod is provided with an anchoring thread, the bottom end of the anchor rod is provided with a connecting piece, a rotating column is installed between the connecting pieces, a pin is rotatably installed on the rotating column, and a bottom cone is installed at the bottom end of the connecting piece.

[0009] Furthermore, the pin has a rotating hole, through which it is rotatably mounted on the rotating column. The pin also has transmission teeth, which mesh with the transmission rod for transmission.

[0010] Furthermore, the bottom end of the transmission rod is provided with several ring teeth, which mesh with the transmission teeth for transmission. The top end of the transmission rod is provided with a second connecting piece, and the transmission rod is rotatably connected to the lever assembly through the second connecting piece.

[0011] The control system activates the drive motor, whose output shaft drives the main gear ring to rotate via the drive gear. The main gear ring then drives the anchoring assembly to rotate via the anchoring gear ring. The control system activates the hydraulic telescopic device, which further compresses the self-balancing base via the push rod. Under pressure and rotation, the anchor rod gradually anchors into the solidified soil. Under the reaction force of the soil, the bottom tray overcomes the elasticity of the support spring and produces a relatively stable ring support sliding. When the anchor rod rotates, the anchoring thread on the anchor rod converts the rotation into linear movement, accelerating the anchor rod's anchoring speed. Once the anchor rod is fully anchored into the solidified soil, the hydraulic telescopic device and drive motor are deactivated. At this point, the stabilizing ring support rests against the surface of the solidified soil, the bottom tray is embedded in the fitting groove at the bottom of the stabilizing ring support, and the support spring is in a compressed state.

[0012] Furthermore, the lever assembly includes a third connector, which is installed inside the base housing. A fixed rotating rod is installed between the third connectors, and a force transmission lever is movably installed on the fixed rotating rod. One end of the force transmission lever is rotatably connected to the transmission rod through the third connector, and a roller is rotatably installed on the other end of the force transmission lever.

[0013] When the locking ring rotates, it synchronously drives the ramp block to rotate. The ramp block gradually squeezes the roller, causing the roller to rotate while being squeezed by the ramp surface, which in turn lifts one end of the force transmission lever. The lifting of one end of the force transmission lever causes its other end to rotate around the fixed rotating rod and descend. The other end of the force transmission lever drives the transmission rod to overcome the elastic force of the return spring and slide down through the second connecting piece. The transmission rod slides downward in the sliding hole and drives the pin that meshes with it to rotate upward through the ring teeth. Several pins rotate and unfold, increasing the contact area between the bottom of the anchor rod and the solidified soil, increasing the anchor rod force, and making the anchor rod more stable. At the same time, by utilizing the lever principle, the downward pressure on the transmission rod is greater, which is more conducive to the pins overcoming the resistance of the surrounding solidified soil and unfolding.

[0014] Furthermore, the locking ring includes a rotating ring, which is rotatably installed inside the base housing. The rotating ring is provided with several force transmission blocks, which are rotatably connected to the cylinder output shaft. The locking ring is provided with several ramp blocks and several pressing blocks. The positions and numbers of the ramp blocks and pressing blocks correspond, and the number of ramp blocks is consistent with that of the rollers.

[0015] Furthermore, the base housing is provided with a second fixing block, which corresponds to the position of the third connecting piece; the locking assembly includes a connecting slide rod, which is slidably mounted on the second fixing block, a snap-fit ​​block is installed at one end of the connecting slide rod, the snap-fit ​​block is provided with snap-fit ​​teeth, and a pressing plate is installed at the other end of the connecting slide rod, with a locking spring installed between the pressing plate and the second fixing block.

[0016] After anchoring is completed, the control system activates the cylinder, the cylinder output shaft extends and drives the locking ring to rotate through the force transmission block. The pressing block on the locking ring gradually rotates and presses the pressing plate. After the pressing plate is pressed, it drives the locking block to extend forward through the connecting slide rod until the locking teeth on the locking block are fully embedded in the tooth groove of the anchoring tooth ring on the anchor rod, thereby completing the locking of the anchor rod and preventing the anchor rod from being squeezed by the surrounding soil and loosening.

[0017] Furthermore, the auxiliary device includes a support, on which a positioning column is mounted, on which an electric lifting platform is slidably mounted, and at the top of the positioning column is a top support. Several first fixed blocks are mounted on the electric lifting platform, and an electric telescopic rod is mounted on each of the first fixed blocks. A bottom support block is mounted on the output shaft of the electric telescopic rod, and a hydraulic telescopic device is mounted on the top support. A connecting plate is mounted on the output shaft of the hydraulic telescopic device, and a drive motor and a push rod are respectively mounted on the connecting plate. A drive gear is mounted on the output shaft of the drive motor.

[0018] The workers placed the support at the installation position of the self-balancing base, and then assembled the auxiliary device. During the assembly process, the self-balancing base without the first connecting piece was placed on the base block, so that the base block lifted the self-balancing base. After the auxiliary device was assembled, the control system activated the hydraulic telescopic device. The output shaft of the hydraulic telescopic device drove the push rod and drive motor to descend through the connecting plate, so that the push rod contacted the top of the self-balancing base. At this time, it was ensured that the drive gear passed through the connecting hole on the base shell and meshed with the main gear ring. The control system controlled the hydraulic telescopic device and the electric lifting platform to descend synchronously. The hydraulic telescopic device pressed the self-balancing base through the push rod until the bottom cone on the anchor rod was driven into the solidified soil. The control system activated the electric telescopic rod. The output shaft of the electric telescopic rod drove the base block to retract, so that the base block was withdrawn and separated from the contact with the self-balancing base. The self-balancing base was initially driven into the solidified soil with the support of the bottom cone.

[0019] Furthermore, the self-balancing base also includes a first connector, which is installed on the base housing. The self-balancing base is connected to the diagonal brace through the first connector. The top of the base housing is provided with a connection hole for driving the gear into the base housing. The bottom end of the stabilizing ring support is provided with a fitting groove, the size of which corresponds to the bottom tray. The fitting groove is used for the bottom tray to be inserted.

[0020] After the anchoring components are locked, the workers remove the auxiliary device and install the first connector on the base shell. Then, the diagonal brace with the movable end is installed on the first connector, and the movable end is fixed to the foundation pit cap beam, thus completing the installation of the entire diagonal brace device. The support spring inside the self-balancing base will provide an upward thrust to the stabilizing ring. The thrust is transmitted to the bottom end of the diagonal brace through the base shell and the first connector, thereby offsetting part of the downward pressure from the diagonal brace and reducing the load on the self-balancing base. When it is necessary to disassemble the diagonal brace device, the workers reassemble the auxiliary device and reverse the previous steps to disassemble the self-balancing base.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. The locking ring rotates synchronously with the ramp block, which in turn drives the force transmission rod to slide down via a lever assembly. The force transmission rod then drives the engaging pin to rotate and unfold, increasing the contact area between the bottom of the anchor and the solidified soil, thus increasing the anchor's strength and making it more stable. At the same time, the lever principle increases the downward pressure on the transmission rod, making it easier for the pin to overcome the resistance of the surrounding solidified soil and unfold. The multiple anchoring components allow the load transmitted from the brace to the self-balancing base to be automatically and evenly distributed to each anchoring component, ensuring that the self-balancing base is under balanced force and preventing excessive local stress that could lead to instability.

[0023] 2. The hydraulic telescopic device and the drive motor work together to anchor the anchor rod into the solidified soil. The anchoring thread on the anchor rod converts rotation into linear movement, which speeds up the anchor rod's insertion. The stabilizing ring rests against the solidified soil surface, increasing the support area and stability of the self-balancing base and improving the stability of the diagonal brace.

[0024] 3. The cylinder drives the locking ring to rotate, and the pressing block on the locking ring drives the snap-fit ​​block to move forward, so that the snap-fit ​​teeth on the snap-fit ​​block are fully embedded in the tooth groove of the anchoring tooth ring on the anchor rod, thereby achieving the purpose of locking the anchor rod, preventing the anchor rod from being squeezed by the surrounding soil and loosening due to rotation, and improving the stability of the anchoring.

[0025] 4. By inserting the bottom cone nail on the anchor rod into the solidified body, the self-balancing base is initially nailed into the solidified soil, which provides support and fixation for the automatic balancing base, facilitating the further anchoring of subsequent anchor rods; the auxiliary device assists in the installation of the self-balancing base, providing the anchoring power for the self-balancing base, achieving the purpose of automatic installation and disassembly of the self-balancing base, improving the accuracy and efficiency of installation, and reducing manpower input.

[0026] 5. The support spring inside the self-balancing base will exert an upward thrust on the stabilizing ring. The thrust is transmitted to the bottom end of the diagonal brace through the base shell and the first connecting piece, thereby offsetting part of the downward pressure from the diagonal brace and reducing the load on the self-balancing base.

[0047] Anchor rod 331 has a sliding hole 3312 inside, and transmission rod 334 is slidably installed in the sliding hole 3312.

The pin 332 is provided with a transmission tooth 3321. The pin 332 is engaged with the transmission rod 334 through the transmission tooth 3321 for transmission.

[0049] The bottom end of the transmission rod 334 is provided with several ring teeth 3342, which mesh with the transmission teeth 3321 for transmission.

[0050] The locking ring 36 includes a rotating ring 363, which is rotatably installed inside the base housing 31. The rotating ring 363 is provided with a plurality of force transmission blocks 361, which are rotatably connected to the output shaft of the cylinder 365. The locking ring 36 is provided with a plurality of ramp blocks 362 and a plurality of pressing blocks 364. The positions and numbers of the ramp blocks 362 and the pressing blocks 364 correspond, and the number of ramp blocks 362 is the same as that of the rollers 352.

[0051] The base housing 31 is provided with a second fixing block 311, which corresponds to the position of the third connector 353; the locking assembly 39 includes a connecting slide rod 393, which is slidably mounted on the second fixing block 311. One end of the connecting slide rod 393 is provided with a snap-fit ​​block 392, which is provided with snap-fit ​​teeth 3921. The other end of the connecting slide rod 393 is provided with a pressing plate 391, and a locking spring 394 is installed between the pressing plate 391 and the second fixing block 311.

[0052] The lever assembly 35 includes a third connector 353, which is installed inside the base housing 31. A fixed rotating rod 354 is installed between the third connectors 353. A force transmission lever 351 is movably installed on the fixed rotating rod 354. One end of the force transmission lever 351 is rotatably connected to the transmission rod 334 through the third connector 353. A roller 352 is rotatably installed on the other end of the force transmission lever 351.

[0053] The self-balancing base 3 also includes a first connector 30, which is installed on the base housing 31. The self-balancing base 3 is connected to the diagonal brace 1 through the first connector 30. The top of the base housing 31 is provided with a connection hole for driving the gear 48 into the base housing 31. The bottom of the stabilizing ring support 32 is provided with a fitting groove, the size of which corresponds to the bottom tray 34. The fitting groove is used for the bottom tray 34 to be inserted.

[0054] The working principle of this invention: The operator places the support 43 in the installation position of the self-balancing base 3, and then assembles the auxiliary device 4. During the assembly process, the self-balancing base 3 without the first connecting piece 30 is placed on the base support block 443, so that the base support block 443 lifts the self-balancing base 3. After the auxiliary device 4 is assembled, the control system activates the hydraulic telescopic device 45. The output shaft of the hydraulic telescopic device 45 drives the push rod 47 and the drive motor 46 to descend through the connecting plate 451, so that the push rod 47 contacts the top of the self-balancing base 3, and ensures that the drive teeth are engaged at this time. Wheel 48 passes through the connecting hole on the base housing 31 and meshes with the main gear ring 37. The control system controls the hydraulic telescopic device 45 and the electric lifting platform 44 to descend synchronously. The hydraulic telescopic device 45 presses the self-balancing base 3 through the push rod 47 until the bottom cone 3314 on the anchor rod 331 is driven into the solidified soil. The control system activates the electric telescopic rod 442. The output shaft of the electric telescopic rod 442 drives the bottom support block 443 to retract, so that the bottom support block 443 is withdrawn and disengaged from the self-balancing base 3. The self-balancing base 3 is initially driven into the solidified soil under the support of the bottom cone 3314.

[0055] The control system activates the drive motor 46, whose output shaft drives the main gear ring 37 to rotate via the drive gear 48. The main gear ring 37 drives the anchoring assembly 33 to rotate via the anchoring gear ring 3311. The control system activates the hydraulic telescopic device 45, which further compresses the self-balancing base 3 via the push rod 47. Under pressure and rotation, the anchor rod 331 gradually anchors into the solidified soil. Under the action of soil reaction force, the bottom tray 34 overcomes the elastic force of the support spring 38 and generates a relatively stable sliding of the ring support 32. When the anchor rod 331 rotates, the anchoring thread 3313 on the anchor rod 331 converts the rotation into linear movement, which speeds up the anchoring speed of the anchor rod 331. When the anchor rod 331 is completely anchored into the solidified soil, the hydraulic telescopic device 45 and the drive motor 46 are deactivated. At this time, the stable ring support 32 rests against the surface of the solidified soil, the bottom tray 34 is embedded in the fitting groove at the bottom of the stable ring support 32, and the support spring 38 is in a compressed state.

[0056] After anchoring is completed, the control system activates cylinder 365. The output shaft of cylinder 365 extends and drives the locking ring 36 to rotate through the force transmission block 361. The pressing block 364 on the locking ring 36 gradually rotates and presses the pressing plate 391. After being pressed, the pressing plate 391 drives the locking block 392 to extend forward through the connecting slide rod 393 until the locking teeth 3921 on the locking block 392 are fully embedded in the tooth groove of the anchoring tooth ring 3311 on the anchor rod 331, thereby completing the locking of the anchor rod 331 and preventing the anchor rod 331 from being squeezed by the surrounding soil and loosening.

[0057] When the locking ring 36 rotates, it synchronously drives the ramp block 362 to rotate. The ramp block 362 gradually squeezes the roller 352, causing the roller 352 to rotate while being squeezed by the ramp surface, thus lifting one end of the force transmission lever 351. The lifting of one end of the force transmission lever 351 causes its other end to rotate around the fixed rotating rod 354 and descend. The other end of the force transmission lever 351 drives the transmission rod 334 to overcome the elastic force of the return spring 333 and slide down through the second connecting piece 3341. The transmission rod 334 slides downward in the sliding hole 3312 and drives the pin 332 that meshes with it to rotate upward through the ring tooth 3342. Several pins 332 rotate and unfold, increasing the contact area between the bottom of the anchor rod 331 and the solidified soil, increasing the force of the anchor rod 331, and making the anchor rod 331 more stable. At the same time, by utilizing the lever principle, the downward pressure on the transmission rod 334 is greater, which is more conducive to the pins 332 overcoming the resistance of the surrounding solidified soil and unfolding.

[0058] After the anchoring component 33 is locked, the staff removes the auxiliary device 4 and installs the first connector 30 on the base housing 31. Then, the diagonal brace 1 with the movable end 2 is installed on the first connector 30, and the movable end 2 is fixed on the foundation pit cap beam, thus completing the installation of the entire diagonal brace device. The support spring inside the self-balancing base 3 will give the stabilizing ring an upward thrust. The thrust is transmitted to the bottom end of the diagonal brace 1 through the base housing 31 and the first connector 30, thereby offsetting part of the downward pressure from the diagonal brace 1 and achieving the purpose of reducing the load on the self-balancing base 3. When it is necessary to disassemble the diagonal brace device, the staff reassembles the auxiliary device 4 and reverses the previous steps to disassemble the self-balancing base 3.

[0059] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
