Description

Technical Field

[0001] The invention relates to the technical field of subway tunnel equipment, in particular to a subway tunnel steel ring lining reinforcement construction device. Background Art

[0002] Tunnel steel ring lining reinforcement plays many important roles. It can enhance the stability of the tunnel structure, withstand external forces such as pressure from the soil around the tunnel, groundwater pressure, and load from upper buildings, and prevent the tunnel from deformation and collapse. Steel ring lining reinforcement of the tunnel inner wall can repair the existing damaged parts of the tunnel, such as cracks and spalling, and improve the overall structural performance of the tunnel.

[0003] During the reinforcement construction of the tunnel steel ring lining, it is necessary to use manual bolt connection to assemble the steel ring lining. By connecting these parts together with screws, a complete steel ring structure can be formed to ensure the integrity of the steel ring and the accuracy of the circular shape (or other shapes). However, most common installation devices are fixed scaffolding, which is time-consuming and labor-intensive to build, inflexible and bulky, and cannot be flexibly moved according to the installation position, thereby reducing the installation efficiency. Summary of the invention

[0006] Further, two U-shaped limiting rods are fixedly installed at the bottom end of the installation platform. A limiting spring is sleeved on the bidirectional threaded rod. The top end of the limiting spring is fixedly connected to the L-shaped mounting plate, and the bottom end of the limiting spring is fixedly connected to the installation platform.

[0007] Further, L-shaped connecting blocks are respectively hingedly installed on the two support plates. Rectangular sliding grooves are respectively formed in the two L-shaped connecting blocks. Rectangular sliding rods are respectively slidably installed in the two rectangular sliding grooves. The bottom ends of the two rectangular sliding rods respectively extend outside the two rectangular sliding grooves.

[0008] Further, a fixing mechanism is arranged on the bidirectional threaded rod. The fixing mechanism includes an L-shaped internal threaded plate threadedly sleeved on the bidirectional threaded rod. Two fixing boxes are fixed to the top end of the L-shaped internal threaded plate. Both of the two fixing boxes are slidably connected to the base box. Fixing sliders are respectively slidably installed in the two fixing boxes. The bottom ends of the two rectangular sliding rods are respectively fixedly connected to the two fixing sliders.

[0009] Further, two strip-shaped mounting plates are fixedly installed at the bottom of the base box. Two rotating rods are respectively fixedly installed at the bottom of the two strip-shaped mounting plates. A plurality of moving wheels are respectively rotatably installed at the bottom ends of the plurality of rotating rods.

[0010] Further, an adaptor plate is slidably sleeved on the L-shaped mounting plate. The bidirectional threaded rod penetrates through the adaptor plate. An adaptor spring is sleeved on the bidirectional threaded rod. The top end of the adaptor spring is fixedly connected to the adaptor plate, and the bottom end of the adaptor spring is fixedly connected to the base box.

[0011] Further, a stabilizing mechanism is arranged on the two fixing sliders. The stabilizing mechanism includes strip-shaped mounting grooves respectively formed in the two fixing sliders. Support strip-shaped plates are respectively hingedly installed in the two strip-shaped mounting grooves. Limiting sliding grooves are respectively formed on the left side and the right side of the L-shaped internal threaded plate. The two support strip-shaped plates respectively penetrate through the two limiting sliding grooves.

[0012] Further, two L-shaped fixing blocks are respectively fixedly installed on the two L-shaped connecting blocks. Two circular rotating rods are rotatably installed on one side of the plurality of L-shaped fixing blocks close to each other.

[0013] The present invention has the following beneficial effects: (1) A construction device for reinforcing the steel ring lining of a subway tunnel according to the present invention. When in use, the device is moved to the center position of the steel ring, and then the driving motor is started. The driving motor drives the bidirectional threaded rod to rotate. The bidirectional threaded rod drives the first internally threaded plate to rise. During the rising process of the first internally threaded plate, the two support plates are driven to move away from each other. The support plates drive the telescopic platform to slide out of the installation platform. When the support plate contacts the U-shaped limiting rod during movement, the support plate stops moving at this time, and correspondingly, the telescopic platform also stops moving. At this time, the continuous rotation of the bidirectional threaded rod will cause the first internally threaded plate to continue to rise. Since the two telescopic platforms have reached the maximum length, the installation platform and the two telescopic platforms have reached a state convenient for construction. The staff can adjust the position of the installation platform according to the height to be constructed. At this time, the staff will be supported by the support plates above the installation platform and the telescopic platforms, and the stability during operation can be maintained. At the same time, the device is driven mechanically during use, which greatly improves the installation efficiency and construction efficiency. (2) A construction device for reinforcing the steel ring lining of a subway tunnel according to the present invention. During the rotation of the bidirectional threaded rod, the bidirectional threaded rod will drive the L-shaped internally threaded plate to descend. The L-shaped internally threaded plate will drive the two fixed sliders to descend. After the fixed sliders descend, they will contact the ground and jack up the device to make the device stable, avoiding the displacement of the device under the action of the moving wheels during the construction of the workers, resulting in the workers losing their balance and falling from a height. When the support plate moves away from the bidirectional threaded rod, the support plate will drive the L-shaped connecting block to move at the same time. The L-shaped connecting block will drive the rectangular sliding rod to move at the same time. The rectangular sliding rod will drive the two fixed sliders to move away from each other and slide out of the fixed box. At this time, the displacement of the fixed sliders will increase the distance and area of the device contacting the ground, and at the same time improve the stability of the device, thereby further ensuring the safety of the construction personnel. (3) A construction device for reinforcing the steel ring lining of a subway tunnel according to the present invention. During the process of the fixed box and the installation platform moving away from each other, the corresponding L-shaped connecting block will also move away from the fixed slider. The L-shaped connecting block will drive the two L-shaped fixing blocks to move. The L-shaped fixing blocks will drive the circular rotating rod to make a corresponding upward movement. The circular rotating rod will contact and drive the supporting strip plate to rise. When the installation platform reaches the highest point, at this time, the circular rotating rod will also push the supporting strip plate to contact the top inner wall of the limiting chute. At this time, the supporting strip plate is clamped by the limiting chute and the circular rotating rod and is in a fixed state. The fixation of the supporting strip plate will increase the overall stability of the device structure, make the structural connection between the devices closer, and effectively reduce the晃动 of the installation platform when the staff on the installation platform moves. (4) The present invention provides a subway tunnel steel ring lining reinforcement construction device. Since the movement distance of the internal thread plate 1 is greater than the movement distance of the L-shaped internal thread plate, after the L-shaped internal thread plate descends to make the fixed slider lift the device, the bidirectional threaded rod is still rotating. When the L-shaped internal thread plate descends, it will contact and push the adaptive plate to descend. At this time, the adaptive spring undergoes compression deformation. After the adaptive plate leaves the threads on the bidirectional threaded rod, the adaptive plate will be in a semi-disconnected thread state under the elastic force of the adaptive spring. At this time, the fixed slider will not descend, and will not affect the bidirectional threaded rod from driving the installation platform to rise.

[0014] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

Specific implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figure 1 - Figure 8 As shown in the figure, the present invention is a construction device for reinforcing the steel ring lining of a subway tunnel, including a base box 1. A drive motor 2 is fixedly installed on the inner wall of the top of the base box 1. A bidirectional threaded rod 3 is rotatably installed on the top of the base box 1. The bottom end of the bidirectional threaded rod 3 extends into the base box 1 and is fixedly connected to the output shaft of the drive motor 2. An L-shaped mounting plate 4 is fixedly installed on the top of the base box 1. The top end of the bidirectional threaded rod 3 is rotatably connected to the L-shaped mounting plate 4. It further includes: A support mechanism 5. The support mechanism 5 includes a mounting platform 501 slidably installed on the L-shaped mounting plate 4. The bidirectional threaded rod 3 passes through the mounting platform 501. Two telescopic platforms 502 are slidably installed on the mounting platform 501. The mutually remote ends of the two telescopic platforms 502 respectively extend outside the mounting platform 501. An internal threaded plate 503 is threadedly sleeved on the bidirectional threaded rod 3. Two support plates 504 are hingedly installed on the internal threaded plate 503. The top ends of the two support plates 504 are respectively hingedly connected to the two mounting platforms 501.

[0020] As Figure 2 and Figure 3 shown, two C-shaped limiting rods 505 are fixedly installed at the bottom end of the mounting platform 501. A limiting spring 506 is sleeved on the bidirectional threaded rod 3. The top end of the limiting spring 506 is fixedly connected to the L-shaped mounting plate 4. The bottom end of the limiting spring 506 is fixedly connected to the mounting platform 501.

[0021] The support plate 504 drives the telescopic platform 502 to slide out of the installation platform 501. When the support plate 504 contacts the U-shaped limit rod 505 during movement, the support plate 504 stops moving at this time, and correspondingly, the telescopic platform 502 also stops moving. At this time, the continuous rotation of the bidirectional threaded rod 3 will cause the internal threaded plate 1 503 to continuously rise.

[0022] As Figure 4 and Figure 5 shown, L-shaped connecting blocks 507 are respectively hinged and installed on two support plates 504. Rectangular sliding grooves 508 are respectively formed in the two L-shaped connecting blocks 507. Rectangular sliding rods 509 are respectively slidably installed in the two rectangular sliding grooves 508. The bottom ends of the two rectangular sliding rods 509 respectively extend outside the two rectangular sliding grooves 508.

[0023] When the support plate 504 moves away from the bidirectional threaded rod 3, the support plate 504 will drive the L-shaped connecting block 507 to move simultaneously, and the L-shaped connecting block 507 will drive the rectangular sliding rod 509 to move simultaneously.

[0024] As Figure 1 shown, a fixing mechanism 6 is arranged on the bidirectional threaded rod 3. The fixing mechanism 6 includes an L-shaped internal threaded plate 601 threadedly sleeved on the bidirectional threaded rod 3. Two fixing boxes 602 are fixed to the top end of the L-shaped internal threaded plate 601. The two fixing boxes 602 are both slidably connected to the base box 1. Fixing sliders 603 are respectively slidably installed in the two fixing boxes 602. The bottom ends of the two rectangular sliding rods 509 are respectively fixedly connected to the two fixing sliders 603.

[0025] During the rotation of the bidirectional threaded rod 3, the bidirectional threaded rod 3 will drive the L-shaped internal threaded plate 601 to descend. The L-shaped internal threaded plate 601 will drive the two fixing sliders 603 to descend. After the fixing sliders 603 descend, they will contact the ground and jack up the device to make the device stable.

[0026] As Figure 1 shown, two strip-shaped mounting plates 604 are fixedly installed at the bottom of the base box 1. Two rotating rods 605 are respectively fixedly installed at the bottom ends of the two strip-shaped mounting plates 604. A plurality of moving wheels 606 are respectively rotatably installed at the bottom ends of the rotating rods 605.

[0027] When the device needs to be moved, directly push the device to move. The moving wheels 606 will enable the device to move freely, saving the time for installing and fixing the scaffolding and improving the construction efficiency at the same time.

[0028] As Figure 7 shown, an adaptor plate 607 is slidably sleeved on the L-shaped mounting plate 4. The bidirectional threaded rod 3 passes through the adaptor plate 607. An adaptor spring 608 is sleeved on the bidirectional threaded rod 3. The top end of the adaptor spring 608 is fixedly connected to the adaptor plate 607. The bottom end of the adaptor spring 608 is fixedly connected to the base box 1.

[0029] When the L-shaped internal threaded plate 601 descends, it will contact and push the adaptation plate 607 to descend. At this time, the adaptation spring 608 is compressed and deformed. After the adaptation plate 607 leaves the thread on the bidirectional threaded rod 3, the adaptation plate 607 will be in a semi-disconnected thread state under the elastic force of the adaptation spring 608. At this time, the fixed slider 603 will not descend, and will not affect the rise of the installation platform 501 driven by the bidirectional threaded rod 3.

[0030] like Figure 5 and Figure 8 As shown, a stabilizing mechanism 7 is provided on the two fixed sliders 603, and the stabilizing mechanism 7 includes strip mounting grooves 701 respectively opened on the two fixed sliders 603, and supporting strip plates 702 are respectively hingedly installed in the two strip mounting grooves 701, and limiting sliding grooves 703 are respectively opened on the left and right sides of the L-shaped internal thread plate 601, and the two supporting strip plates 702 respectively pass through the two limiting sliding grooves 703.

[0031] The supporting strip plate 702 is clamped in a fixed state by the limiting slide groove 703 and the circular rotating rod 705. The fixation of the supporting strip plate 702 will increase the overall stability of the device structure, make the structural connection between the devices closer, and effectively reduce the shaking of the installation platform 501 when the staff on the installation platform 501 are active.

[0032] like Figure 5 As shown, two L-shaped fixing blocks 704 are fixedly mounted on the two L-shaped connecting blocks 507 respectively, and two circular rotating rods 705 are rotatably mounted on one side of the plurality of L-shaped fixing blocks 704 close to each other.

[0033] The L-shaped connecting block 507 will drive the two L-shaped fixing blocks 704 to move, and the L-shaped fixing block 704 will drive the circular rotating rod 705 to make a corresponding upward movement. The circular rotating rod 705 will contact and drive the supporting strip plate 702 to rise. When the installation platform 501 reaches the highest point, the circular rotating rod 705 will also push the supporting strip plate 702 to contact the top inner wall of the limiting slide groove 703.

[0034] When in use, move the device to the center position of the steel ring, and then start the driving motor 2. The driving motor 2 drives the bidirectional threaded rod 3 to rotate. The bidirectional threaded rod 3 drives the first internally threaded plate 503 to rise. During the rising process of the first internally threaded plate 503, it drives the two support plates 504 to move away from each other. The support plates 504 drive the telescopic platform 502 to slide out of the installation platform 501. When the support plate 504 contacts the C-shaped limiting rod 505 during movement, the support plate 504 stops moving at this time, and correspondingly, the telescopic platform 502 also stops moving. At this time, the continuous rotation of the bidirectional threaded rod 3 will cause the first internally threaded plate 503 to continue to rise. Since the two telescopic platforms 502 have reached the maximum length, the installation platform 501 and the two telescopic platforms 502 have reached a state convenient for construction. The staff can adjust the position of the installation platform 501 according to the height to be constructed. At this time, the staff will be supported by the support plate 504 above the installation platform 501 and the telescopic platform 502; during the rotation of the bidirectional threaded rod 3, the bidirectional threaded rod 3 will drive the L-shaped internally threaded plate 601 to descend. The L-shaped internally threaded plate 601 will drive the two fixed sliders 603 to descend. After the fixed sliders 603 descend, they will contact the ground and jack up the device to make the device stable, avoiding the displacement of the device under the action of the moving wheels 606 during the construction of the workers, resulting in the workers' center of gravity being unstable and falling from a height. When the support plate 504 moves away from the bidirectional threaded rod 3, the support plate 504 will drive the L-shaped connecting block 507 to move simultaneously. The L-shaped connecting block 507 will drive the rectangular sliding rod 509 to move simultaneously. The rectangular sliding rod 509 will drive the two fixed sliders 603 to move away from each other and slide out of the fixed box 602. At this time, the displacement of the fixed sliders 603 will increase the distance and area where the device contacts the ground; During the process of the fixed box 602 and the installation platform 501 moving away from each other, the corresponding L-shaped connecting block 507 will also move away from the fixed slider 603. The L-shaped connecting block 507 will drive the two L-shaped fixing blocks 704 to move. The L-shaped fixing blocks 704 will drive the circular rotating rod 705 to make a corresponding upward movement. The circular rotating rod 705 will contact and drive the supporting strip plate 702 to rise. When the installation platform 501 reaches the highest point, at this time, the circular rotating rod 705 will also push the supporting strip plate 702 to contact the top inner wall of the limiting chute 703. At this time, the supporting strip plate 702 is clamped and fixed by the limiting chute 703 and the circular rotating rod 705, making the structural connection between the devices closer; Since the moving distance of the first internally threaded plate 503 is greater than the moving distance of the L-shaped internally threaded plate 601, after the L-shaped internally threaded plate 601 descends to jack up the device by the fixed slider 603, the bidirectional threaded rod 3 is still rotating. When the L-shaped internally threaded plate 601 descends, it will contact and push the adapting plate 607 to descend. At this time, the adapting spring 608 undergoes a compressive deformation. After the adapting plate 607 leaves the thread on the bidirectional threaded rod 3, the adapting plate 607 will be in a semi-disengaged state from the thread under the elastic force of the adapting spring 608.

The preferred embodiments do not describe all the details in detail, nor do they limit the invention to the specific implementation methods described. Obviously, many modifications and changes can be made according to the content of this specification. This specification selects and specifically describes these embodiments in order to better explain the principles and practical applications of the present invention, so that those skilled in the art can understand and use the present invention well.
