Description

Technical Field

[0001] The invention relates to the technical field of diagonal bracing devices, in particular to a diagonal bracing device for a solidified soil section with a self-balancing function. Background Art

[0002] In the complex and critical engineering field of deep foundation pit construction, inclined steel support plays a vital role with its unique advantages. It not only provides a solid support for the foundation pit, ensuring the safety and stability during the construction process, but also demonstrates comprehensive benefits in many aspects. The inclined steel support has extremely high adaptability and flexibility. Deep foundation pit construction often faces complex construction environments and geological conditions, and the inclined steel support can be adjusted according to actual needs to adapt to the construction needs of foundation pits of different depths, different soil types and different terrains. This highly adaptable feature makes the inclined steel support widely used in deep foundation pit construction.

[0003] However, the existing diagonal bracing device has a relatively single support point and cannot evenly transfer the upper force to the hardened soil. The single force form makes it easy for the support base to have an unbalanced force, which can seriously lead to support deformation and even foundation pit collapse, increasing construction risks. In addition, the existing support system often requires a lot of manpower during installation, and the level of automation and intelligence is low, which can hardly meet production needs. Summary of the invention

[0007] Furthermore, the anchoring assembly includes an anchor rod, which is meshed with the main gear ring for transmission. The anchor rod is rotatably installed on the base shell, and the anchor rod passes through the bottom tray. A transmission rod is movably installed in the anchor rod, and the transmission rod is rotatably connected to the anchor assembly. A reset spring is installed between the transmission rod and the anchor rod, and a number of pins are rotatably installed on the anchor rod, and the transmission rod and the pins are meshed for transmission.

[0009] Furthermore, a rotating hole is provided on the pin piece, and the pin piece is rotatably installed on the rotating column through the rotating hole. A transmission tooth is provided on the pin piece, and the pin piece is meshed with the transmission rod for transmission through the transmission tooth.

[0010] Furthermore, a plurality of ring teeth are provided at the bottom end of the transmission rod, and the ring teeth are meshed with the transmission teeth for transmission. A second connecting piece is provided at the top end of the transmission rod, and the transmission rod is rotatably connected to the lever assembly through the second connecting piece.

[0011] The control system starts the driving motor, and the output shaft of the driving motor drives the main gear ring to rotate through the driving gear, and the main gear ring drives the anchor assembly to rotate through the anchor gear ring. The control system starts the hydraulic telescopic device, and the hydraulic telescopic device further squeezes the self-balancing base through the push rod. The anchor rod is gradually anchored into the solidified soil under the action of pressure and rotation. Under the action of the reaction force of the soil, the bottom tray overcomes the elastic force of the supporting spring and produces a relatively stable slip of the ring support. When the anchor rod rotates, the anchoring thread on the anchor rod converts the rotation into linear movement, which speeds up the anchoring speed of the anchor rod. When the anchor rod is completely anchored into the solidified soil, the hydraulic telescopic device and the driving motor are turned off. At this time, the stabilizing ring support is against the surface layer of the solidified soil, the bottom tray is embedded in the fitting groove at the bottom of the stabilizing ring support, and the supporting spring is in a compressed state.

[0012] Furthermore, the lever assembly includes a third connecting member, which is installed in the base shell, a fixed rotating rod is installed between the third connecting members, 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 connecting member, and a roller is rotatably installed on the other end of the force transmission lever.

[0013] When the locking ring rotates, it simultaneously drives the ramp block to rotate, and the ramp block gradually squeezes the roller, so that the roller rotates and drives one end of the force transmission lever to lift up under the squeezing of the slope surface. The lifting of one end of the force transmission lever causes the other end to rotate around the fixed rotating rod and descend, and 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, and the transmission rod slides downward in the sliding hole and drives the pin piece engaged with it to rotate upward through the ring teeth. Several pin pieces rotate and unfold, which increases the contact area between the bottom of the anchor rod and the solidified soil, increases the strength of the anchor rod, and makes the anchor rod more stable. At the same time, the lever principle is used to make the transmission rod subject to greater downward pressure, which is more conducive to the pin piece overcoming the resistance of the surrounding solidified soil and unfolding.

[0014] Furthermore, the locking ring includes a rotating ring, which is rotatably installed in the base shell, and a plurality of force transmission blocks are provided on the rotating ring, and the force transmission blocks are rotatably connected to the cylinder output shaft, and a plurality of ramp blocks are provided on the locking ring, and a plurality of extrusion blocks are provided on the locking ring, and the positions and quantities of the ramp blocks correspond to those of the extrusion blocks, and the number of the ramp blocks is consistent with that of the rollers.

[0016] After anchoring is completed, the control system starts the cylinder, the cylinder output shaft extends and drives the locking ring to rotate through the force transmission block, the extrusion block on the locking ring gradually rotates and squeezes the extrusion plate, and the extrusion plate is compressed and drives the clamping block forward through the connecting slide rod until the clamping teeth on the clamping block are completely 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 rotating loose.

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

[0018] The operator places the support at the installation position of the self-balancing base, and then assembles the auxiliary device. During the assembly process, the self-balancing base without the first connecting piece installed is placed on the bottom support block, so that the bottom support block lifts the self-balancing base. After the auxiliary device is assembled, the control system turns on the hydraulic telescopic device, and the output shaft of the hydraulic telescopic device drives the push rod and the drive motor to descend through the connecting plate, so that the push rod contacts the top of the self-balancing base, and ensures that the drive gear passes through the connecting hole on the base shell and engages with the main gear ring at this time. The control system controls the hydraulic telescopic device and the electric lifting platform to descend synchronously, and the hydraulic telescopic device presses the self-balancing base through the push rod until the bottom cone on the anchor rod is nailed into the solidified soil. The control system turns on the electric telescopic rod, and the output shaft of the electric telescopic rod drives the bottom support block to retract, so that the bottom support block is withdrawn and disengaged from the contact with the self-balancing base, and the self-balancing base is initially nailed into the solidified soil under the support of the bottom cone.

[0019] Furthermore, the self-balancing base also includes a first connecting member, which is installed on the base shell.

A connecting hole is provided at the top of the base shell, and the connecting hole is used to drive the gear to enter the base shell. An embedding groove is provided at the bottom end of the stabilizing ring bracket. The size of the embedding groove corresponds to that of the bottom tray, and the embedding groove is used for the bottom tray to be embedded.

[0020] After the anchor assembly is locked, the staff will evacuate the auxiliary device and install the first connecting piece on the base shell, and then install the diagonal support rod with a flexible end on the first connecting piece, and fix the flexible end on the crown beam of the foundation pit, thereby completing the installation of the entire diagonal support device. The support spring in the self-balancing base will give the stabilizing ring an upward thrust, and the thrust is transmitted to the bottom end of the diagonal support rod through the base shell and the first connecting piece, thereby offsetting part of the downward pressure from the diagonal support rod, thereby achieving the purpose of reducing the load on the self-balancing base; when the diagonal support device needs to be disassembled, the staff will assemble the auxiliary device again, reverse the previous steps, and disassemble the self-balancing base.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The locking ring rotates to synchronously drive the ramp block to rotate. The ramp block drives the force transmission rod to slide down through the lever assembly. The force transmission rod drives the pin piece engaged with it to rotate and unfold, which increases the contact area between the bottom of the anchor rod and the solidified soil, increases the strength of the anchor rod, and makes the anchor rod more stable. At the same time, the lever principle is used to make the downward pressure on the transmission rod greater, which is more conducive to the pin piece to overcome the resistance of the surrounding solidified soil and unfold; the setting of multiple groups of anchoring assemblies allows the load transmitted to the self-balancing base by the diagonal support rod to be automatically and evenly distributed to each anchoring assembly, so that the self-balancing base is balanced and the instability of the self-balancing base caused by excessive local force is prevented.

[0023] 2. The hydraulic telescopic device and the drive motor cooperate with each other 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 anchoring speed; the stabilizing ring is supported on the solidified soil surface, which increases the supporting area and stability of the self-balancing base and improves the stability of the diagonal support rod.

[0024] 3. The cylinder is used to drive the locking ring to rotate, and the extrusion block on the locking ring drives the clamping block to move forward, so that the clamping teeth on the clamping block are completely embedded in the tooth grooves of the anchoring tooth ring on the anchor rod, thereby locking the anchor rod and preventing the anchor rod from being squeezed by the surrounding soil and rotating loose, thereby 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 supports and fixes the automatic balancing base and facilitates the further anchoring of the subsequent anchor rods; the auxiliary device is used to assist in the installation of the self-balancing base, providing anchoring power for the self-balancing base, so as to achieve the purpose of automatic installation and disassembly of the self-balancing base, improve the accuracy and efficiency of installation, and reduce manpower input.

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

[0053] The self-balancing base 3 also includes a first connecting member 30, which is installed on the base shell 31. The self-balancing base 3 is connected to the diagonal support rod 1 through the first connecting member 30. A connecting hole is provided at the top of the base shell 31, and the connecting hole is used to drive the gear 48 to enter the base shell 31. An embedding groove is provided at the bottom end of the stabilizing ring bracket 32. The size of the embedding groove corresponds to that of the bottom tray 34, and the embedding groove is used for the bottom tray 34 to be embedded.

[0054] The working principle of the present invention is as follows: the operator places the support 43 at 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 member 30 is placed on the bottom support block 443, so that the bottom support block 443 lifts the self-balancing base 3. After the auxiliary device 4 is assembled, the control system turns on the hydraulic telescopic device 45, and 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 gear 46 is in contact with the top of the self-balancing base 3 at this time. The wheel 48 passes through the connecting hole on the base shell 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 nailed into the solidified soil. The control system turns on the electric telescopic rod 442. The output shaft of the electric telescopic rod 442 drives the bottom supporting block 443 to retract, so that the bottom supporting block 443 is withdrawn and disengaged from the contact with the self-balancing base 3. The self-balancing base 3 is initially nailed into the solidified soil under the support of the bottom cone 3314.

[0055] The control system starts the drive motor 46, and the output shaft of the drive motor 46 drives the main gear ring 37 to rotate through the drive gear 48, and the main gear ring 37 drives the anchor assembly 33 to rotate through the anchor gear ring 3311. The control system starts the hydraulic telescopic device 45, and the hydraulic telescopic device 45 further squeezes the self-balancing base 3 through the push rod 47. The anchor rod 331 is gradually anchored into the solidified soil under the action of pressure and rotation. Under the action of the reaction force of the soil, the bottom tray 34 overcomes the elastic force of the support spring 38 and produces a relative slip of the stable 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 turned off. At this time, the stable ring support 32 is against the surface layer of the solidified soil, and 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 starts the cylinder 365, the output shaft of the cylinder 365 extends and drives the locking ring 36 to rotate through the force transmission block 361, the extrusion block 364 on the locking ring 36 gradually rotates and squeezes the extrusion plate 391, and the extrusion plate 391 is compressed and drives the clamping block 392 to extend forward through the connecting slide rod 393 until the clamping teeth 3921 on the clamping block 392 are completely 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 rotating loose.

[0057] When the locking ring 36 rotates, the ramp block 362 is driven to rotate synchronously. The ramp block 362 gradually squeezes the roller 352, so that the roller 352 rotates and drives one end of the force transmission lever 351 to lift under the squeezing of the slope surface. The lifting of one end of the force transmission lever 351 causes the 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 piece 332 engaged with it to rotate upward through the ring tooth 3342. A number of pin pieces 332 rotate and unfold, which increases the contact area between the bottom of the anchor rod 331 and the solidified soil, increases the strength of the anchor rod 331, and makes the anchor rod 331 more stable. At the same time, by using the lever principle, the transmission rod 334 is subjected to a greater downward pressure, which is more conducive to the pin piece 332 to overcome the resistance of the surrounding solidified soil and unfold.

[0058] After the anchor assembly 33 is locked, the staff will remove the auxiliary device 4 and install the first connecting piece 30 on the base shell 31, and then install the diagonal support rod 1 equipped with the flexible end 2 on the first connecting piece 30, and fix the flexible end 2 on the crown beam of the foundation pit, thereby completing the installation of the entire diagonal support device. The supporting spring in the self-balancing base 3 will give an upward thrust to the stabilizing ring, and the thrust is transmitted to the bottom end of the diagonal support rod 1 through the base shell 31 and the first connecting piece 30, thereby offsetting part of the downward pressure from the diagonal support rod 1, thereby achieving the purpose of reducing the load on the self-balancing base 3; when it is necessary to disassemble the diagonal support device, the staff will assemble the auxiliary device 4 again, reverse the previous steps, and disassemble the self-balancing base 3.

[0059] It will be apparent to those skilled in the art that the 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 the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
