Description

Technical Field

[0001] This invention relates to the field of tunnel construction technology, and more specifically, to a rapid positioning support frame and support method for lining steel reinforcement binding. Background Technology

[0002] During tunnel construction, reinforced concrete lining is a key link to ensure structural safety and stability. The rapid positioning support frame for lining reinforcement binding is a professional piece of equipment designed to improve the efficiency and quality of tunnel lining reinforcement binding. By integrating rapid positioning and stable support functions, it solves the problems of low efficiency and poor accuracy in traditional construction methods. At the same time, it enhances the adaptability to different tunnel cross sections, which helps to improve the overall safety and reliability of the project.

[0003] However, the quick positioning support frame for lining reinforcement binding lacks a precise adjustment mechanism in actual use, making it difficult to meet the requirements for reinforcement spacing, protective layer thickness, and arc contour. Especially in tunnel cross-sections with large curvature changes, problems such as reinforcement misalignment and layering are prone to occur, affecting the structural stress performance. At the same time, the quick positioning support frame for lining reinforcement binding is mostly a fixed structure in actual use, which cannot flexibly adapt to the lining requirements of different diameters, cross-sectional shapes, or construction stages, resulting in low equipment versatility and the need for frequent replacement or remanufacturing.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a rapid positioning support frame and support method for lining reinforcement binding, which has the advantages of the aforementioned technical problems and thus solves the problems in existing technologies.

[0007] (II) Technical Solution

[0008] To achieve the advantages of solving the aforementioned technical problems, the specific technical solution adopted by the present invention is as follows:

[0009] A quick positioning support frame for tying reinforcing bars in lining includes a support base plate, a support component one and a support component two respectively arranged above the support base plate, and an auxiliary component arranged below the support base plate.

[0010] The support component includes a support base plate with multiple electric telescopic rods 1 installed above it. One end of each electric telescopic rod 1 is equipped with a mounting base. One side of the mounting base is connected to an electric telescopic rod 2 via a rotating rod 1. One end of each electric telescopic rod 2 is connected to an arc-shaped support frame via a rotating rod 1. The lower part of the arc-shaped support frame is connected to the upper part of the mounting base.

[0011] Furthermore, in order to better assist in the positioning and support of the lining reinforcement, the second support component includes an auxiliary frame set above the support base plate, multiple motors staggered on both sides of the auxiliary frame, and rotating shafts staggered on both sides of the auxiliary frame. One end of the rotating shaft and one end of the motor are set with a fixed seat. A multi-stage electric telescopic rod is set on the fixed seat. One end of the multiple multi-stage electric telescopic rods is connected to a support cover through a rotating rod. A support pressing roller is set inside the support cover.

[0012] Furthermore, in order to better support the base plate, the auxiliary components include multiple auxiliary slots below the base plate, with movable wheels inside the auxiliary slots, and a moving track connected below the movable wheels. A dual-axis motor is installed on one side of the multiple movable wheels. Multiple auxiliary holes are opened below the auxiliary frame, with an electric telescopic rod installed inside the auxiliary holes. A support base is installed at one end of the electric telescopic rod, and the support base contacts the top of the moving track.

[0013] Furthermore, in order to better support the support cover, there are multiple support platforms in contact with the bottom of the support cover, and one end of the support platform is connected to the top of the support base plate.

[0014] Furthermore, to better assist workers in carrying out rebar tying operations, multiple support platforms are set on both sides of the auxiliary frame, and ladders are installed on the support platforms, the auxiliary frame, and the support base plate.

[0015] Furthermore, in order to better support the tied steel bars and transport the steel bars, multiple multi-stage electric telescopic rods are installed above the support base plate, and an auxiliary support plate is installed at one end of each multi-stage electric telescopic rod.

[0016] Furthermore, in order to better place the tied reinforcing bars and facilitate better transportation, a reinforcing bar placement cavity is provided on the top of the auxiliary support plate and on one side of the arc-shaped support frame.

[0017] Furthermore, in order to restrict the arc-shaped support frame, multiple restriction plates are installed inside the arc-shaped support frame, and an electromagnet is installed on one side of the restriction plate.

[0018] Furthermore, in order to better restrict the arc-shaped support frame, electromagnet one is magnetically connected to electromagnet two, and a limiting frame is connected to one side of electromagnet two. The lower part of the limiting frame is connected to the upper part of the support base plate.

[0019] This application also provides a support method for the aforementioned quick positioning support frame for lining reinforcement binding, comprising the following steps:

[0020] S1. Start the dual-axis motor. The dual-axis motor drives the moving wheels on both sides of the support base plate to rotate synchronously, so that the support base plate moves forward or backward smoothly along the preset moving track, and accurately transports the support frame to the lining section to be constructed in the tunnel. During the movement, the moving wheels are always embedded in the moving track to prevent lateral deviation and ensure the straightness of the equipment's trajectory and the accuracy of repeatability.

[0021] S2. When the support base plate reaches the target position, the controller commands the electric telescopic rod three to extend downwards. The electric telescopic rod three pushes the support seat to press tightly against the upper surface of the moving track, forming a rigid fulcrum. Multiple electric telescopic rod threes move synchronously, so that the support base plate is lifted, finely adjusted and firmly locked, eliminating the shaking caused by uneven ground or vibration, and providing a stable foundation platform for subsequent steel reinforcement support.

[0022] S3. The controller synchronously starts multiple electric telescopic rods 1 and 2. The electric telescopic rod 2 works in coordination through a spatial linkage mechanism consisting of a mounting base and a rotating rod 1. The electric telescopic rod 1 is responsible for vertical height adjustment, while the electric telescopic rod 2 controls the inclination angle and curvature expansion of the arc support frame. The linkage between the electric telescopic rod 1 and the electric telescopic rod 2 enables the arc support frame to dynamically adjust its spatial posture so that its inner contour completely matches the lining curvature of the current tunnel section.

[0023] S4. After the arc-shaped support frame is adjusted into place, electromagnet one is energized to generate magnetic force. Electromagnet one and electromagnet two on the same side form a strong magnetic attraction. Electromagnet one is fixed to the limiting plate, while electromagnet two is connected to the limiting frame. The bottom of the limiting frame is fixed to the support base plate. This magnetic connection provides rigid constraint to the arc-shaped support frame in both the horizontal and vertical directions, preventing it from rebounding or displacing due to external forces during the placement or binding of the reinforcing bars.

[0024] S5. Then, the second multi-stage electric telescopic rod extends upward simultaneously, and the second multi-stage electric telescopic rod drives the auxiliary support plate to rise to the predetermined height. The top surface of the auxiliary support plate and the inner wall of the arc-shaped support frame are aligned with the steel bar placement cavity on one side to ensure that the placed steel bars can slide in smoothly and be initially limited to avoid rolling or misalignment.

[0025] S6. When the operation begins, the motor starts and drives the fixed seat to rotate through the shaft, thereby changing the initial angle of the multi-stage electric telescopic rod. Subsequently, the multi-stage electric telescopic rod extends in stages, pushing the support cover closer to the rebar area. The support pressing rollers inside the support cover continue to apply controllable pressure after contacting the rebar, pressing the rebar tightly against the inner wall of the rebar placement cavity or between adjacent rebars. The bottom of the support cover contacts the support platform to ensure the stability of the support cover when not in operation. Multiple support covers can operate independently or in groups to adapt to the local positioning needs of rebars in different locations.

[0026] S7. Construction workers climb ladders to the support platform, which is located on both sides of the auxiliary frame, providing a safe and spacious operating space. During the binding process, the controller continuously receives real-time data from sensors and dynamically fine-tunes the output status of electric telescopic rod one, electric telescopic rod two, multi-stage electric telescopic rod one, multi-stage electric telescopic rod two, and electric telescopic rod three. When insufficient pressure is detected at a certain point, the controller automatically increases the downward pressure of the corresponding support pressing roller. After binding a section, the controller can instruct electromagnet one and electromagnet two to be de-energized and unlocked, and then retract the electric telescopic mechanism to reset the arc-shaped support frame, facilitating the equipment to move forward into the next construction section.

[0027] (III) Beneficial Effects

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] (1) By setting support components one and two on the support base plate, the shape and size can be quickly adjusted to adapt to the lining requirements of different diameters, cross-sectional shapes or construction stages, ensuring the accurate positioning of the steel bar spacing, protective layer thickness and arc contour. Especially in tunnel cross sections with large curvature changes, it can effectively avoid steel bar misalignment and misalignment, ensure the structural stress performance, improve the stability and accuracy of steel bars under complex curvature conditions, and also assist in pressing and positioning the steel bars, improve the versatility of steel bar binding, and reduce the equipment replacement cost caused by changes in construction requirements. The auxiliary components set on the support base plate not only provide a stable support foundation, which is conducive to improving construction safety, but also reduce construction quality problems caused by equipment shaking.

[0030] (2) By setting up multi-level electric telescopic rods and auxiliary support plates on the support base plate, the actual position of the lining steel bars and construction requirements can be adjusted to ensure that the steel bars are always accurately positioned during the binding process and improve the stability of the steel bars in complex construction environments. Meanwhile, the electromagnets one and two set up on the limiting plate can provide flexible limiting functions for the arc support frame and ensure the stability of the support frame under various complex conditions.

[0048] like Figure 1 - Figure 6 As shown in the embodiments of this application, a support method for a quick positioning support frame for lining reinforcement binding is disclosed, including the following steps:

[0049] S1. Start the dual-axis motor 403. The dual-axis motor 403 drives the moving wheels 401 on both sides of the support base plate 1 to rotate synchronously, so that the support base plate 1 moves forward or backward smoothly along the preset moving track 402, and accurately transports the support frame to the lining section to be constructed in the tunnel. During the movement, the moving wheels 401 are always embedded in the moving track 402 to prevent lateral deviation and ensure the straightness of the equipment's trajectory and the accuracy of repeatability positioning.

[0050] S2. When the support base plate 1 reaches the target position, the controller commands the electric telescopic rod 404 to extend downward. The electric telescopic rod 404 pushes the support seat 405 to press tightly against the upper surface of the moving track 402, forming a rigid fulcrum. Multiple electric telescopic rods 404 move synchronously, so that the support base plate 1 is lifted, finely adjusted and firmly locked, eliminating the shaking caused by uneven ground or vibration, and providing a stable foundation platform for subsequent steel reinforcement support.

[0051] S3. The controller synchronously starts multiple electric telescopic rods 1 201 and electric telescopic rod 203. Electric telescopic rod 203 works in coordination through a spatial linkage mechanism formed by mounting base 202 and rotating rod 1. Electric telescopic rod 1 201 is responsible for vertical height adjustment, while electric telescopic rod 203 controls the inclination angle and curvature expansion of the arc support frame 204. The linkage between electric telescopic rod 1 201 and electric telescopic rod 203 causes the arc support frame 204 to dynamically adjust its spatial posture so that its inner contour completely fits the lining curvature of the current tunnel section.

[0052] S4. After the arc-shaped support frame 204 is adjusted into place, the electromagnet 12 is energized to generate magnetic force. The electromagnet 12 and the corresponding electromagnet 23 on one side form a strong magnetic attraction. The electromagnet 12 is fixed on the limiting plate 11, while the electromagnet 23 is connected to the limiting frame 14. The bottom of the limiting frame 14 is fixed on the supporting base plate 1. This magnetic connection achieves rigid constraint on the arc-shaped support frame 204 in both the horizontal and vertical directions, preventing it from rebounding or displacing due to external forces during the placement or binding of the reinforcing bars.

[0053] S5. Then, the multi-stage electric telescopic rod 28 extends upward simultaneously, and the multi-stage electric telescopic rod 28 drives the auxiliary support plate 9 to rise to the predetermined height. The top surface of the auxiliary support plate 9 and the steel bar placement cavity 10 on one side of the inner wall of the arc-shaped support frame 204 ensure that the placed steel bar can slide in smoothly and be initially limited to avoid rolling or misalignment.

[0054] S6. When the operation begins, the motor 302 starts and drives the fixed seat 304 to rotate through the rotating shaft 303, thereby changing the initial angle of the multi-stage electric telescopic rod 305. Subsequently, the multi-stage electric telescopic rod 305 extends in stages, pushing the support cover 306 closer to the rebar area. The support pressing roller 307 set inside the support cover 306 continues to apply controllable pressure after contacting the rebar, pressing the rebar tightly against the inner wall of the rebar placement cavity 10 or between adjacent rebars. The bottom of the support cover 306 contacts the support platform 5 to ensure the stability of the support cover 306 when not in operation. Multiple support covers 306 can operate independently or in groups to adapt to the local positioning needs of rebars in different locations.

[0055] S7. Construction workers climb ladder 7 to the support platform 6. The support platform 6 is set on both sides of the auxiliary frame 301, providing a safe and spacious operating space. During the binding process, the controller continuously receives real-time data from the sensors and dynamically fine-tunes the output status of electric telescopic rod 1 201, electric telescopic rod 203, multi-stage electric telescopic rod 1 305, multi-stage electric telescopic rod 2 8, and electric telescopic rod 3 404. When insufficient pressure is detected at a certain point of the rebar, the controller automatically increases the downward pressure of the corresponding support pressing roller 307. After binding a section, the controller can instruct electromagnet 1 12 and electromagnet 2 13 to be de-energized and unlocked, and then retract the electric telescopic mechanism to reset the arc-shaped support frame 204, facilitating the equipment to move forward into the next construction section.

The top surface of the auxiliary support plate (9) and the steel bar placement cavity (10) on one side of the inner wall of the arc support frame (204) ensure that the placed steel bar can slide in smoothly and be initially limited to avoid rolling or misalignment. S6. When the operation begins, the motor (302) starts and drives the fixed seat (304) to rotate through the rotating shaft (303), thereby changing the initial angle of the multi-stage electric telescopic rod (305). Then, the multi-stage electric telescopic rod (305) extends in stages and pushes the support cover (306) closer to the rebar area. The support pressing roller (307) set inside the support cover (306) continues to apply controllable pressure after contacting the rebar, pressing the rebar tightly against the inner wall of the rebar placement cavity (10) or between adjacent rebars. The bottom of the support cover (306) contacts the support platform (5) to ensure the stability of the support cover (306) when not working. Multiple support covers (306) can operate independently or in groups to adapt to the local positioning needs of rebars in different parts. S7. Construction workers climb the ladder (7) to the support platform (6). The support platform (6) is set on both sides of the auxiliary frame (301) to provide a safe and spacious operating space. During the binding process, the controller continuously receives real-time data from the sensor and dynamically fine-tunes the output status of the electric telescopic rod one (201), electric telescopic rod two (203), multi-stage electric telescopic rod one (305), multi-stage electric telescopic rod two (8) and electric telescopic rod three (404). When the pressure of a certain steel bar is insufficient, the corresponding support pressing roller (307) is automatically increased. After binding a section, the electromagnet one (12) and electromagnet two (13) can be de-energized and unlocked. The electric telescopic mechanism is then retracted to reset the arc support frame (204), making it easier for the equipment to move forward into the next construction section.
