Description

Technical Field

[0001] The present invention relates to the technical field of tunnel construction, and in particular to mechanized installation equipment for steel corrugated plates and an installation method thereof. Background Art

[0002] With the rapid development of infrastructure construction in my country, the number of underground structures, such as tunnels, is increasing. However, as tunnels age, internal quality risks in tunnel linings gradually become apparent. These include insufficient lining thickness, concrete defects, and voids behind the lining. These issues directly reduce the bearing capacity of tunnel lining structures and can even lead to catastrophic consequences such as structural deformation, fracture, and collapse, seriously threatening tunnel operational safety.

[0003] To address the structural defects of tunnel linings, various reinforcement methods have been proposed and applied in practical engineering. Among them, corrugated steel plate reinforcement has attracted much attention due to its excellent mechanical properties and durability. This method involves installing corrugated steel plates on the inner wall of the tunnel lining to form a sleeve structure, effectively improving the lining's overall load-bearing capacity and waterproofing performance. However, traditional corrugated steel plate installation methods have many drawbacks that limit their effectiveness in practical engineering applications:

[0004] Inefficient construction: Traditional corrugated steel installation methods typically rely on manual labor or simple machinery, resulting in slow construction and a failure to meet the demands of large-scale, high-efficiency construction. This is particularly true in existing railway tunnel reinforcement projects, where limited construction time (e.g., 60 to 120 minutes per day) makes it difficult to complete the reinforcement within the stipulated timeframe using traditional methods.

[0005] Significant safety risks: During the installation of the corrugated steel sheeting, inherent defects in the lining structure and the need for temporary support or removal of the lining during installation increase safety risks. In particular, during the installation of the corrugated steel sheeting after the temporary steel arch is removed, the lining could fall off again, posing a serious threat to construction workers and equipment.

[0006] Installation accuracy is difficult to ensure: Due to the discrepancy between the curve of the tunnel lining's inner wall and theoretical design, as well as the tunnel's slopes and curvatures, traditional corrugated steel plate installation methods struggle to guarantee the accuracy of each plate. Particularly during circumferential and longitudinal installation, cumulative errors can result in the final ring of plates being misaligned, potentially encroaching on the train's operating space or too close to the overhead contact line.

[0007] In view of the drawbacks of the above-mentioned traditional corrugated steel plate installation method, the present invention aims to provide a mechanized installation device and an installation method for corrugated steel plates. Summary of the Invention

[0008] In order to solve the above problems, the present invention provides a mechanized installation device for corrugated steel plates and an installation method thereof. The mechanized installation device for corrugated steel plates and the installation method thereof effectively solve the disadvantages of traditional corrugated steel plate installation methods, such as low construction efficiency, great safety hazards, and difficulty in ensuring installation accuracy.

[0009] The technical solutions of the present invention are as follows:

[0010] The mechanized installation equipment for corrugated steel plates is fixedly installed at the end of the boom of the mobile lifting equipment, and includes a fixed seat, a rotating seat and a movable seat. The fixed seat is fixedly connected to the end of the boom, and the rotating seat is rotatably installed on the fixed seat. The fixed seat is provided with a rotating drive device for driving the rotating seat to rotate. The movable seat is connected to the rotating seat through a detachable plug-in mechanism. An electromagnet for picking up the corrugated steel plates is installed at the end of the movable seat away from the rotating seat, and the end of the movable seat close to the rotating seat is fixedly connected to the lifting rope of the mobile lifting equipment.

[0011] The detachable plug-in mechanism includes a fixed end arranged on the rotating seat and a movable end arranged on the movable seat. The fixed end is a cylindrical structure. The outer shape of the movable end is matched with the inner hole clearance of the fixed end. The movable end can be inserted into the fixed end. A horizontal strip-shaped locking hole is provided on the movable end, and a self-locking spring pin that cooperates with the locking hole is provided on the rotating seat.

[0012] Two parallel locking holes are arranged in the upper and lower directions of the movable end.

[0013] The movable end is hinged on the movable seat, and a movable limiter is installed between the middle part of the movable end and the movable seat.

[0014] The movable limiter includes a cylinder body and a telescopic rod that cooperate with each other. The ends of the cylinder body and the telescopic rod are hinged to the movable seat and the movable end respectively. A slide groove is provided on the telescopic rod, and a fixing bolt is installed on the cylinder body. The end of the fixing bolt is tightened and pressed against the slide groove to lock the telescopic rod on the cylinder body.

[0015] The rotation driving device includes a driving motor and a worm gear mechanism. A worm gear is fixedly arranged on the fixed seat, and a worm gear matched with the worm gear and driven by the driving motor is installed on the rotating seat.

[0016] The rotating seat is installed on the fixed seat through a bearing.

[0017] The mobile lifting equipment is a truck crane.

[0018] The mechanized installation method of the steel corrugated plate comprises the following steps: fixing the fixed seat to the end of the boom of the mobile lifting equipment, and fixing the movable end of the movable seat to the lifting rope of the mobile lifting equipment. The steps of lifting the steel corrugated plate include:

[0019] S1: shorten the boom to its shortest position and lower it to the lowest position;

[0020] S2: Release the self-locking spring latch, move the lifting equipment to loosen the lifting rope and allow the movable seat to descend to the position where the steel corrugated plate is placed;

[0021] S3: The corrugated steel plate is sucked onto the movable seat by an electromagnet;

[0022] S4: The mobile lifting equipment tightens the lifting rope to make the movable seat rise so that the movable end is inserted into the fixed end until the self-locking spring pin is inserted into the bar-shaped locking hole;

[0023] S5: The boom of the mobile lifting equipment is raised;

[0024] S6: Adjust the boom of the mobile lifting equipment so that the fixed base is in a horizontal state;

[0025] S7: The rotating seat is driven by the rotating driving device to rotate so that the steel corrugated plate rotates 180 degrees from the lower end to the upper end;

[0026] S8: Move the steel corrugated sheet to the location to be installed by extending and retracting the boom of the mobile lifting equipment and raising and lowering the boom;

[0027] S9: After the installation is complete, continue with steps S1-S8.

[0028] Step S8 also includes the following steps:

[0029] S81: Finely adjust the position of the movable seat relative to the rotating seat along the direction of the strip locking hole or the telescopic direction of the movable limiter within the range of the strip locking hole or the telescopic range of the movable limiter.

[0030] The beneficial effects of the present invention are:

[0031] 1. The mechanized installation equipment and installation method of steel corrugated plates disclosed in the present invention realize the rapid and efficient installation of steel corrugated plates through mechanized means, significantly improving the construction speed. Compared with traditional manual or simple mechanical installation methods, the mechanized installation equipment can complete more work in a shorter time, and is particularly suitable for time-constrained construction scenarios such as railway tunnel reinforcement projects.

[0032] 2. The mechanized installation equipment and installation method of steel corrugated plates disclosed in the present invention reduce safety risks: in traditional installation methods, due to defects in the lining structure itself and the need to temporarily support or remove the lining during the installation process, the safety risks in the construction process are increased; while the present invention uses mechanized installation equipment to reduce the need for direct manual operation, reduce the threat to construction personnel and equipment caused by accidents such as lining falling off, and improve construction safety.

[0033] 3. The mechanized installation equipment and installation method of steel corrugated plates disclosed in the present invention ensure installation accuracy: the curve of the inner wall of the tunnel lining is different from the theoretical design, and the tunnel has slopes and curvatures. Traditional installation methods are difficult to ensure the installation accuracy of each steel plate; the present invention uses precisely designed mechanized installation equipment to accurately control the installation position and angle of the steel corrugated plates, avoids the existence of cumulative errors, ensures the installation accuracy of each steel plate, and prevents safety hazards caused by installation positions that do not meet requirements.

[0034] 4. The mechanized installation equipment and installation method of steel corrugated plates disclosed in the present invention improve construction flexibility: the mechanized installation equipment and installation method of steel corrugated plates in the present invention are designed with a detachable plug-in mechanism and a rotation drive device, so that the movable seat can be adjusted and rotated relative to the fixed seat, thereby adapting to the installation requirements of steel corrugated plates at different angles and positions; making the equipment more adaptable and versatile in the complex and changeable tunnel construction environment.

DETAILED DESCRIPTION

[0043] The present invention will be further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification. This is to avoid the core portion of the present application being overwhelmed by excessive descriptions, and for those skilled in the art, it is not necessary to describe these related operations in detail. They will fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0044] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0045] like Figures 1 to 4 As shown, the mechanized installation equipment for steel corrugated plates mainly consists of a fixed seat 2, a rotating seat 3, a movable seat 4 and related driving and connecting mechanisms, and is combined with mobile lifting equipment (such as a truck crane) to complete the picking, rotation and installation of the steel corrugated plates 1.

[0046] The fixing base 2 is the supporting base of the entire installation equipment. It is fixedly connected to the end of the boom of the mobile lifting equipment and is made of high-strength steel to ensure that it can withstand the weight of the steel corrugated plate 1 and various operating forces during the installation process.

[0047] The connection between the fixed base 2 and the end of the boom is made of high-strength bolts. The connection parts are precisely machined to ensure the connection accuracy and stability. At the same time, the connection parts are equipped with anti-loosening devices to prevent the bolts from loosening due to vibration and other reasons during operation.

[0048] The rotating seat 3 is mounted on the fixed seat 2 via a bearing. The bearing adopts a high-precision rolling bearing with the characteristics of low friction, high load capacity and long life. A fixed end 34 is provided on the rotating seat 3. The fixed end 34 adopts a specially designed slot structure. Its internal dimensions match the movable end 42 of the movable seat 4 to ensure that the movable end 42 can be smoothly inserted and achieve a stable connection. In this embodiment, the fixed end 34 is a cylindrical structure.

[0049] A rotation drive device is provided on the rotating base 3, comprising a drive motor 31 and a worm gear mechanism. The drive motor 31 is fixedly mounted on the rotating base 3. In the worm gear mechanism, the worm wheel 21 is fixedly mounted on the fixed base 2, and both ends of the worm 32 are mounted on the rotating base 3 via bearings. Driven by the drive motor 31, the worm 32 drives the worm wheel 21 to rotate, thereby achieving rotation of the rotating base 3. The worm gear mechanism has a self-locking function, which can maintain the position of the rotating base 3 stable when the drive stops, preventing the rotating base 3 from accidentally rotating due to external forces. Rope holes 33 are provided at the upper and lower relative positions of the rotating base 3, through which the rope 6 of the mobile lifting equipment passes. A pulley 8 for guiding the rope 6 is also provided on the rotating base 3, and the pulley 8 is mounted on the rotating base 3 via a bracket 9.

[0050] The movable seat 4 is the direct load-bearing component of the steel corrugated plate 1. It is made of lightweight but high-strength alloy material to reduce the overall weight of the equipment while ensuring sufficient load-bearing capacity. The shape of the movable seat 4 is designed according to the appearance of the steel corrugated plate 1 to ensure that it can fit closely with the steel corrugated plate 1 and improve the stability of picking up and installation.

[0051] An electromagnet 41 is installed at the end of the movable seat 4 away from the rotating seat 3. The electromagnet 41 adopts high-performance permanent magnetic materials and advanced electromagnetic control technology, has strong suction and fast response speed, and the suction of the electromagnet 41 can be adjusted according to the weight and installation requirements of the steel corrugated plate 1 to ensure that the steel corrugated plate 1 can be firmly adsorbed during the picking and installation process.

[0052] The movable seat 4 is connected to the rotating seat 3 through a detachable plug-in mechanism.

[0053] The removable insertion mechanism includes a fixed end 34 provided on the rotating base 3 and a movable end 42 provided on the movable base 4. The movable end 42 is also cylindrical in structure, with its outer circumference being a cylindrical shape that fits within the cylindrical inner hole of the fixed end 34. The movable end 42 can be inserted into the fixed end 34. The movable end 42 is provided with two horizontally parallel strip-shaped locking holes 43. The height of the locking holes 43 is sized to ensure that the self-locking spring latch 5 can be properly inserted, while the width of the locking holes 43 is sized to ensure that the movable end 42 can rotate 5° to 10° relative to the rotating base 3.

[0054] The movable end 42 is hinged on the movable seat 4, and a movable limiter 7 is installed between the middle part and the movable seat 4. The movable limiter 7 adopts a mechanical limit structure. By adjusting the position of the limiter, the rotation angle of the movable seat 4 relative to the fixed seat 2 can be limited to ensure that the angle of the movable seat 4 meets the requirements during installation.

[0055] like Figure 5As shown, the movable limiter 7 includes a cylinder body 71 and a telescopic rod 72 that cooperate with each other. The ends of the cylinder body 71 and the telescopic rod 72 are hinged to the movable seat 4 and the movable end 42 respectively. A slide groove 74 is provided on the telescopic rod 72, and a fixing bolt 73 is installed on the cylinder body 71. The end of the fixing bolt 73 is tightened and pressed against the slide groove 74 to lock the telescopic rod 72 on the cylinder body 71.

[0056] The self-locking spring latch 5 is arranged on the rotating seat 3 and cooperates with the locking hole 43 on the movable end 42. The self-locking spring latch 5 is made of a high-strength spring 52 and a latch body 51. The head of the latch body 51 is provided with an inclined surface, and the inclined surface of the latch body 51 faces the square of the movable end 42 inserted into the fixed end 34. When the movable end 42 is inserted into the fixed end 34, the movable end 42 will first push against the inclined surface of the latch body 51 to move the latch body 51 outward. When the latch body 51 reaches the locking hole 43, the latch body 51 is automatically inserted into the locking hole 43 under the action of the spring 52, thereby locking the movable seat 4 and the fixed seat 2. When the movable seat 4 needs to be disassembled, the latch 51 only needs to be pulled outward, and the latch body 51 can be withdrawn from the locking hole 43, realizing the rapid disassembly of the movable seat 4.

[0057] One end of the lifting rope 6 is fixedly connected to the end of the movable base 4 near the rotating base 3, and the other end is connected to the hook of the mobile lifting equipment. To ensure the reliability of the connection between the lifting rope 6 and the movable base 4, a special connection device is installed at the connection point. This device is fixed with high-strength bolts and clamps and has undergone rigorous mechanical testing to ensure that it will not loosen or break during the lifting process.

[0058] Based on the above mentioned mechanized installation equipment for corrugated steel sheets, see Figure 6 The installation method of this embodiment includes the following detailed steps:

[0059] 1. Preparation

[0060] Equipment Inspection and Commissioning: Before installation begins, conduct a comprehensive inspection and commissioning of the mechanized steel corrugated sheet installation equipment. Check the secure connections of the fixed base 2, rotating base 3, and movable base 4, the flexibility of all rotating parts, and the proper functioning of electrical equipment such as the drive motor 31 and electromagnet 41. Functional tests should be conducted on key components such as the self-locking spring latch 5 and movable limiter 7 to ensure proper operation. Furthermore, adjust various equipment parameters, such as the suction force of the electromagnet 41 and the rotational speed of the rotary drive, based on the specifications and installation requirements of the corrugated steel sheet 1.

[0061] Site layout and preparation: Drive a mobile lifting device (such as a truck crane) to the installation site, ensuring it is parked in a stable position and that the boom can reach the placement and installation locations of the corrugated steel sheet 1. Place clear safety warning signs on site and demarcate a safe working area to prevent unauthorized access. Prepare the necessary tools and materials for installation, such as wrenches, screwdrivers, and measuring instruments.

[0062] 2. Preparation for lifting

[0063] Boom adjustment: shorten the boom of the mobile lifting equipment to the shortest position and lower it to the lowest position so as to be close to the placement of the corrugated steel plate 1.

[0064] The self-locking spring latch 5 is released: the operator reaches the vicinity of the fixed seat 2 and manually pulls out the latch body of the self-locking spring latch 5 so that the latch body 51 withdraws from the locking hole 43, preparing for the descent of the movable seat 4.

[0065] 3. Pick up corrugated steel sheets

[0066] Lowering the movable seat 4: The mobile crane operator slowly lowers the movable seat 4 to the location where the corrugated steel sheet 1 is placed by loosening the lifting rope 6. During the descent, the position and speed of the movable seat 4 must be closely monitored to ensure a smooth descent and avoid collision with surrounding objects. The operator must also maintain constant communication with the ground control team and adjust the position of the movable seat 4 according to their instructions.

[0067] 4. Electromagnet 41 Adsorbs the Steel Corrugated Plate: When the movable seat 4 descends to a suitable position above the steel corrugated plate 1, the operator activates the electromagnet 41, generating a strong suction force that securely attaches the steel corrugated plate 1 to the movable seat 4. During the adsorption process, it is important to ensure that the contact surface between the electromagnet 41 and the steel corrugated plate 1 is in full contact to improve adsorption stability. After adsorption is complete, the operator checks the adsorption to confirm that the steel corrugated plate 1 is securely attached to the movable seat 4.

[0068] 5. Raise and lock

[0069] Ascending the movable seat 4: The operator of the mobile lifting equipment slowly ascends the movable seat 4 by tightening the lifting rope 6. During the ascending process, the movable seat 4 must be kept stable to avoid shaking or tilting. Furthermore, the relative position of the movable seat 4 and the fixed seat 2 must be closely observed to ensure that the movable end 42 can be smoothly inserted into the fixed end 34.

[0070] Self-locking spring latch 5 locks: When the movable end 42 is fully inserted into the fixed end 34, the latch body 51, under the action of the spring 52, automatically inserts into the locking hole 43, locking the movable seat 4 and the rotating seat 3. The operator should check that the latch body 51 is fully inserted into the locking hole 43 to ensure reliable locking. If the latch body 51 is not fully inserted or is loose, it should be adjusted and corrected promptly.

[0071] 6. Adjust the boom

[0072] Lifting the boom: Slowly lift the boom of the mobile crane to lift the corrugated steel plate 1 to a certain height to prepare for subsequent rotation and installation operations. During the lifting process, keep the boom stable to avoid sudden stops or starts to prevent damage to the corrugated steel plate 1 and the equipment.

[0073] Horizontal adjustment of the fixed base 2: The operator adjusts the boom angle and position of the mobile lifting equipment to make the fixed base 2 in a horizontal state. Horizontal adjustment is an important step to ensure the accuracy of the subsequent installation of the corrugated steel plate 1. The operator must make adjustments carefully and meticulously.

[0074] 7. Rotating steel corrugated plate

[0075] The rotation drive device starts: The operator starts the drive motor 31 of the rotation drive device. The drive motor 31 drives the worm 32, which in turn drives the worm wheel 21, thereby rotating the rotating base 3. During the rotation process, the rotation of the corrugated steel plate 1 should be closely observed to ensure that it rotates smoothly and at a moderate speed. At the same time, the operating status of the rotation drive device should be monitored, such as for any abnormal sounds or vibrations. If any abnormalities are found, the machine should be stopped and inspected immediately. At this time, the suspension rope 6 should be loosened.

[0076] Rotating the corrugated steel plate 1 into position: In this embodiment, the drive motor's operating time or rotation angle is controlled to rotate the corrugated steel plate 1 180° from the bottom to the top, achieving a convenient installation position. This device allows the rotating base 3 to be positioned at any angle relative to the fixed base 2. After rotation into position, the drive motor is turned off, stopping the rotating base 3. At this point, the position of the corrugated steel plate 1 must be reconfirmed to ensure it meets installation requirements.

[0077] 8. Move to the installation location

[0078] Boom Extension and Lifting: The mobile crane operator controls the boom's extension and lifting to slowly move the corrugated steel sheet 1 to the installation location. During this movement, the boom must be kept stable and accurate to avoid deviations or collisions with surrounding objects. The boom's speed and direction must be appropriately adjusted based on the actual site conditions and installation requirements.

[0079] Angle fine-tuning: After the corrugated steel plate 1 is moved to the vicinity of the installation location, the angle of the movable seat 4 relative to the rotating seat 3 is adjusted as needed along the direction of the bar locking hole or the extension and contraction direction of the movable stopper 7 within the range of the bar locking hole or the extension and contraction range of the movable stopper 7. By rotating the adjusting bolt 73 to adjust the limiting angle of the movable stopper 7, the angle of the movable seat 4 can be precisely fine-tuned to ensure that the installation angle of the corrugated steel plate 1 meets the design requirements.

[0080] 9. Install corrugated steel sheets

[0081] Positioning and Fixing: Once the corrugated steel sheet 1 has arrived at its intended installation location, operators collaborate with ground installation personnel to position and secure it. Bolting, welding, or other methods are used to securely attach the sheet 1 to the tunnel lining. During installation, strict adherence to installation procedures and specifications is essential to ensure quality.

[0082] Electromagnet 41 is powered off: After the installation of the steel corrugated plate 1 is completed, the operator turns off the electromagnet 41, so that the electromagnet 41 loses its suction force and separates the movable seat 4 from the steel corrugated plate 1. At this time, a comprehensive inspection of the installation is required to confirm whether the steel corrugated plate 1 is installed firmly and the position is accurate.

[0083] 10. Repeat the operation

[0084] Equipment reset: After installation is completed, the mobile crane operator resets the movable seat 4 to its initial position to prepare for the installation of the next corrugated steel plate. The boom is shortened to its shortest position, lowered to the lowest position, and the self-locking spring latch 5 is released to allow the movable seat 4 to descend freely.

[0085] Circular installation: Repeat the installation of the next steel corrugated plate according to the above steps S1 to S8 until the entire reinforcement project is completed. During the cyclic installation process, it is necessary to continuously summarize experience, optimize the operation process, and improve installation efficiency and quality.
