Description

Technical Field

[0001] This utility model relates to the field of tunnel construction technology, specifically to a mechanized installation device for corrugated steel plates. Background Technology

[0002] With the rapid development of infrastructure construction in my country, the number of underground structures such as tunnels is increasing. However, as tunnels have been in operation for longer periods, internal quality issues related to tunnel linings are gradually emerging, such as insufficient lining thickness, concrete defects, and voids behind the lining. These problems directly reduce the load-bearing capacity of the tunnel lining structure and may even lead to catastrophic consequences such as structural deformation, fracture, and collapse, seriously threatening the safety of tunnel operation.

[0003] To address the structural defects in tunnel linings, various reinforcement methods have been proposed and applied in practical engineering. Among them, the corrugated steel plate reinforcement method has attracted considerable 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 lining structure, effectively improving the overall load-bearing capacity and waterproofing performance of the lining. However, traditional corrugated steel plate installation methods have several drawbacks, limiting their application effectiveness in practical engineering.

[0004] Low construction efficiency: Traditional corrugated steel plate installation methods typically rely on manual labor or simple machinery, resulting in slow construction speeds that cannot meet the demands of large-scale, high-efficiency construction. This is particularly true in railway tunnel reinforcement projects, where limited construction time (e.g., only 60-120 minutes per day) makes it difficult to complete the reinforcement task within the stipulated timeframe using traditional methods.

[0005] Significant safety hazards: During the installation of corrugated steel plates, inherent defects in the lining structure and the need for temporary support or removal of the lining during installation increase safety risks. Particularly during the installation of corrugated steel plates after removing temporary steel arches, the lining may detach again, posing a serious threat to construction personnel and equipment.

[0006] Installation accuracy is difficult to guarantee: Due to the difference between the curve of the tunnel lining inner wall and the theoretical design, and the existence of slope and curvature in the tunnel, the traditional corrugated steel plate installation method is difficult to guarantee the installation accuracy of each steel plate. Especially in the circumferential and longitudinal installation process, due to the existence of cumulative errors, the installation position of the last ring of steel plates may not meet the requirements, or even encroach on the train running space or be too close to the catenary.

[0007] In view of the drawbacks of the traditional corrugated steel plate installation methods, this utility model aims to provide a mechanized installation device for corrugated steel plates. Summary of the Invention

[0008] To address the aforementioned problems, this utility model provides a mechanized installation device for corrugated steel plates. This device effectively solves the drawbacks of traditional corrugated steel plate installation methods, such as low construction efficiency, significant safety hazards, and difficulty in guaranteeing installation accuracy.

[0009] The technical solution of this utility model is as follows:

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

[0011] Furthermore, the detachable insertion mechanism includes a fixed end set on the rotating seat and a movable end set on the movable seat. The fixed end has a cylindrical structure, and the outer shape of the movable end is clearance-fitted with the inner hole of the fixed end. The movable end can be inserted into the fixed end. A transverse strip-shaped locking hole is provided on the movable end, and a self-locking spring pin that mates with the locking hole is provided on the rotating seat.

[0012] Furthermore, the movable end has two parallel locking holes arranged vertically.

[0013] Furthermore, the movable end is hinged to the movable seat, and a movable limiter is installed between the middle of the movable end and the movable seat.

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

[0015] Furthermore, the rotation drive device includes a drive motor and a worm gear mechanism. A worm wheel is fixedly mounted on a fixed base, and a worm gear that is driven by the drive motor and cooperates with the worm wheel is mounted on a rotating base.

[0016] Furthermore, the rotating seat is mounted on the fixed seat via bearings.

[0017] Furthermore, the mobile lifting equipment is a truck crane.

[0018] Furthermore, the rotating base has rope holes at its upper and lower relative positions for threading the rope, and pulleys for guiding the rope are installed on the rotating base via brackets.

[0019] Furthermore, the worm gear and worm constitute a self-locking transmission mechanism, which can self-lock and maintain the current position of the rotating seat when the drive motor stops.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. This utility model discloses a mechanized installation equipment for corrugated steel sheets. This equipment enables rapid and efficient installation of corrugated steel sheets through mechanized means, significantly improving 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.

[0022] 2. The present invention discloses a mechanized installation equipment for corrugated steel plates, which reduces safety risks: In traditional installation methods, due to defects in the lining structure itself, and the need for temporary support or dismantling of the lining during installation, the safety risks during construction are increased; while the present invention, through mechanized installation equipment, reduces the need for direct manual operation, reduces the threat to construction personnel and equipment caused by unexpected situations such as lining detachment, and improves construction safety.

[0023] 3.

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Similar elements in different embodiments are referred to by related similar element reference numerals. In the following embodiments, many details are described to facilitate a better understanding of the present application. However, those skilled in the art will readily recognize that some features may be omitted in different situations, or may be replaced by other elements, materials, or methods. In some cases, certain operations related to the present application are not shown or described in the specification. This is to avoid obscuring the core parts of the present application with excessive description. For those skilled in the art, detailed description of these related operations is not necessary; they can fully understand the related operations based on the description in the specification and general technical knowledge in the art.

[0034] Furthermore, the features, operations, or characteristics described in the specification can be combined in any suitable manner to form various embodiments. At the same time, the steps or actions in the method description can be rearranged or adjusted in a manner obvious to those skilled in the art. Therefore, the various orders in the specification and drawings are only for the clear description of a particular embodiment and do not imply a necessary order, unless otherwise stated that a particular order must be followed.

[0035] like Figures 1 to 4As shown, the mechanized installation equipment for corrugated steel sheets mainly consists of a fixed base 2, a rotating base 3, a movable base 4, and related drive and connection mechanisms. It is combined with mobile lifting equipment (such as a truck crane) to complete the picking, rotating, and installation of corrugated steel sheets 1.

[0036] The fixed base 2 is the supporting foundation 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 corrugated steel plate 1 and various operating forces during the installation process.

[0037] The connection between the fixed base 2 and the end of the boom is made of high-strength bolts, and the connection parts are precision machined to ensure connection accuracy and stability. At the same time, anti-loosening devices are installed at the connection parts to prevent the bolts from loosening due to vibration or other reasons during equipment operation.

[0038] The rotating seat 3 is mounted on the fixed seat 2 via a bearing. The bearing is a high-precision rolling bearing, which has the characteristics of low friction, high load capacity and long service life. The rotating seat 3 is provided with a fixed end 34. 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.

[0039] A rotation drive device is provided on the rotating seat 3, which includes a drive motor 31 and a worm gear mechanism. The drive motor 31 is fixedly mounted on the rotating seat 3. In the worm gear mechanism, the worm wheel 21 is fixedly mounted on the fixed seat 2, and the two ends of the worm 32 are mounted on the rotating seat 3 through bearings. Driven by the drive motor 31, the worm 32 drives the worm wheel 21 to rotate, thereby realizing the rotation of the rotating seat 3. The worm gear mechanism has a self-locking function, which can keep the position of the rotating seat 3 stable when the drive stops, preventing the rotating seat 3 from rotating accidentally due to external forces. There are rope holes 33 at the upper and lower relative positions of the rotating seat 3. The lifting rope 6 of the moving lifting equipment passes through the rope holes 33. A pulley 8 for guiding the lifting rope 6 is also provided on the rotating seat 3. The pulley 8 is mounted on the rotating seat 3 through a bracket 9.

[0040] The movable seat 4 is the direct load-bearing component of the corrugated steel 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 shape of the corrugated steel plate 1 to ensure that it can fit tightly with the corrugated steel plate 1 and improve the stability of picking and installation.

[0041] 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 magnet material and advanced electromagnetic control technology, which has strong attraction and fast response speed. The attraction of the electromagnet 41 can be adjusted according to the weight of the steel corrugated plate 1 and the installation requirements to ensure that the steel corrugated plate 1 can be firmly attracted during the picking and installation process.

[0042] The movable seat 4 is connected to the rotating seat 3 via a detachable insertion mechanism.

[0043] The detachable insertion mechanism includes a fixed end 34 mounted on the rotating base 3 and a movable end 42 mounted on the movable base 4. The movable end 42 is also a cylindrical structure, with its outer circumference being a cylinder that fits with the inner cylindrical hole of the fixed end 34 with a clearance. 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 sufficient to ensure that the self-locking spring pin 5 can be inserted precisely, while the width of the locking holes 43 should be sufficient to allow the movable end 42 to rotate 5° to 10° relative to the rotating base 3.

[0044] The movable end 42 is hinged to the movable base 4, and a movable limiter 7 is installed between the middle part and the movable base 4. The movable limiter 7 adopts a mechanical limiting structure. By adjusting the position of the limiter, the rotation angle of the movable base 4 relative to the fixed base 2 can be limited, ensuring that the angle of the movable base 4 meets the requirements during installation.

[0045] like Figure 5 As shown, the movable limiter 7 includes a cylinder 71 and a telescopic rod 72 that are mutually telescopically coordinated. The ends of the cylinder 71 and the telescopic rod 72 are respectively hinged to the movable seat 4 and the movable end 42. A sliding groove 74 is provided on the telescopic rod 72. A fixing bolt 73 is installed on the cylinder 71. The end of the fixing bolt 73 is tightened and presses against the sliding groove 74 to lock the telescopic rod 72 onto the cylinder 71.

[0046] The self-locking spring pin 5 is mounted on the rotating seat 3 and engages with the locking hole 43 on the movable end 42. The self-locking spring pin 5 is made of a high-strength spring 52 and a pin body 51. The head of the pin body 51 has a bevel, with the bevel facing the square section where the movable end 42 inserts into the fixed end 34. When the movable end 42 is inserted into the fixed end 34, the movable end 42 first pushes against the bevel of the pin body 51, causing the pin body 51 to move outward. When the pin body 51 reaches the locking hole 43, it automatically inserts into the locking hole 43 under the action of the spring 52, thus locking the movable seat 4 and the fixed seat 2. When the movable seat 4 needs to be disassembled, simply pull the pin 51 outward, and the pin body 51 will exit from the locking hole 43, enabling quick disassembly of the movable seat 4.

[0047] One end of the lifting rope 6 is fixedly connected to the end of the movable seat 4 near the rotating seat 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 seat 4, a special connecting device is set at the connection point. This device is fixed with high-strength bolts and clamps and has undergone rigorous mechanical testing to ensure that there will be no loosening or breakage during the lifting process.

[0048] See Figure 6 The installation method of the installation equipment in this embodiment includes the following detailed steps:

[0049] 1. Preparation stage

[0050] Equipment Inspection and Debugging: Before commencing installation, a comprehensive inspection and debugging of the mechanized installation equipment for corrugated steel sheets is conducted. This includes checking the secure connections of components such as the fixed base 2, rotating base 3, and movable base 4; ensuring the flexibility of all rotating parts; and verifying the proper functioning of electrical equipment such as the drive motor 31 and electromagnet 41. Functional tests are performed on key components such as the self-locking spring pin 5 and the movable limit switch 7 to ensure their normal operation. Simultaneously, based on the specifications and installation requirements of the corrugated steel sheet 1, various parameters of the equipment are adjusted, such as the attraction force of the electromagnet 41 and the rotation speed of the drive device.

[0051] Site setup and preparation: Drive the mobile lifting equipment (such as a truck crane) to the installation site, ensuring its stable parking position and that the boom can cover the placement location of the corrugated steel sheet 1 and the area to be installed. Set up clear safety warning signs on site, demarcate a safe working area, and prevent unauthorized personnel from entering. Prepare the necessary tools and materials for installation, such as wrenches, screwdrivers, and measuring instruments.

[0052] 2. Lifting preparation

[0053] Boom adjustment: Retract the boom of the mobile lifting equipment to its shortest length and lower it to the lowest position so as to approach the location where the corrugated steel plate 1 is placed.

[0054] Self-locking spring pin 5 released: When the operator reaches the vicinity of the fixed seat 2, he manually pulls the pin body of the self-locking spring pin 5 outward, so that the pin body 51 exits from the locking hole 43, preparing for the descent of the movable seat 4.

[0055] 3. Pick up the corrugated steel sheet

[0056] Lowering of Movable Seat 4: The operator of the mobile crane controls the slack of the hoisting rope 6, causing the movable seat 4 to slowly descend to the location where the corrugated steel plate 1 is placed. During the descent, the position and descent speed of the movable seat 4 must be closely observed to ensure a smooth descent and avoid collisions with surrounding objects. Simultaneously, the operator must maintain constant communication with the ground command personnel and adjust the position of the movable seat 4 according to their instructions.

[0057] 4. Electromagnet 41 adsorbs the corrugated steel sheet: When the movable seat 4 descends to a suitable position above the corrugated steel sheet 1, the operator activates the electromagnet 41, causing it to generate a strong attraction force that firmly adsorbs the corrugated steel sheet 1 onto the movable seat 4. During the adsorption process, it is essential to ensure that the contact surfaces of the electromagnet 41 and the corrugated steel sheet 1 are fully in contact to improve the stability of the adsorption. After adsorption is complete, the operator must check the adsorption to confirm that the corrugated steel sheet 1 is firmly adsorbed onto the movable seat 4.

[0058] 5. Rise and lock

[0059] Movable seat 4 rises: The operator of the mobile lifting equipment controls the tension of the hoisting rope 6 to slowly raise the movable seat 4. During the raising process, the movable seat 4 must be kept stable to avoid swaying or tilting. At the same time, 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.

[0060] Self-locking spring pin 5 locking: After the movable end 42 is inserted into the fixed end 34, the pin body 51 automatically inserts into the locking hole 43 under the action of the spring 52, realizing the locking of the movable seat 4 and the rotating seat 3. The operator should check whether the pin body 51 is fully inserted into the locking hole 43 to ensure reliable locking. If the pin body 51 is found to be not fully inserted or to be loose, it should be adjusted and dealt with in time.

[0061] 6. Adjust the boom

[0062] Boom lifting: Slowly lift the boom of the mobile lifting equipment to raise the corrugated steel plate 1 to a certain height, preparing for subsequent rotation and installation operations. During the boom lifting process, keep the boom stable and avoid sudden stops or starts to prevent damage to the corrugated steel plate 1 and the equipment.

[0063] Horizontal adjustment of fixed base 2: The operator adjusts the angle and position of the boom of the mobile lifting equipment to ensure that fixed base 2 is horizontal. Horizontal adjustment is a crucial step in ensuring the subsequent installation accuracy of the corrugated steel plate 1, and the operator must perform the adjustment carefully and meticulously.

[0064] 7. Rotating corrugated steel plate

[0065] Starting the rotation drive device: The operator starts the drive motor 31 of the rotation drive device. The drive motor 31 drives the worm gear 32 to rotate, and the worm gear 32 then drives the worm wheel 21 to rotate, thereby realizing the rotation of the rotating seat 3. During the rotation process, the rotation of the corrugated steel plate 1 should be closely observed to ensure that its rotation is smooth and at a moderate speed. At the same time, attention should be paid to the operating status of the rotation drive device, such as whether there are any abnormal sounds or vibrations. If any abnormalities are found, the machine should be stopped immediately for inspection; at this time, the lifting rope 6 should be loosened first.

[0066] The corrugated steel plate 1 is rotated into position: In this embodiment, by controlling the running time or rotation angle of the drive motor, the corrugated steel plate 1 is rotated 180° from the lower end to the upper end, reaching a position convenient for installation. This device allows for any angle between the rotating seat 3 and the corresponding fixed seat 2. After rotating into position, the drive motor is turned off, stopping the rotation of the rotating seat 3. At this time, the position of the corrugated steel plate 1 should be reconfirmed to ensure it meets the installation requirements.

[0067] 8. Move to the installation location.

[0068] Boom extension and lifting: The operator of the mobile lifting equipment controls the extension and lifting of the boom to slowly move the corrugated steel plate 1 to the installation position. During the movement, it is essential to maintain the stability and accuracy of the boom to avoid deviations or collisions with surrounding objects. Simultaneously, the boom's speed and direction of movement should be adjusted appropriately according to the actual site conditions and installation requirements.

[0069] Angle fine-tuning: After moving the corrugated steel plate 1 to the vicinity of the installation position, adjust the angle of the movable seat 4 relative to the rotating seat 3 as needed, within the range of the strip locking hole or the extension / retraction range of the movable limiter 7, along the direction of the strip locking hole or the extension / retraction range of the movable limiter 7. Adjust the limiting angle of the movable limiter 7 by rotating the adjusting fixing bolt 73, thereby achieving precise fine-tuning of the angle of the movable seat 4 and ensuring that the installation angle of the corrugated steel plate 1 meets the design requirements.

[0070] 9. Install corrugated steel sheets

[0071] Positioning and Fixing: Once the corrugated steel sheet 1 reaches its installation location, the operators, in coordination with the ground installation personnel, position and fix the corrugated steel sheet 1. Bolts, welding, or other connection methods are used to securely install the corrugated steel sheet 1 onto the inner wall of the tunnel lining. During installation, strict adherence to installation procedures and specifications is crucial to ensure installation quality.

[0072] Electromagnet 41 de-energized: After the corrugated steel plate 1 is installed, the operator turns off the electromagnet 41, causing it to lose its attraction, and separates the movable seat 4 from the corrugated steel plate 1. At this time, a comprehensive inspection of the installation should be carried out to confirm whether the corrugated steel plate 1 is installed firmly and in the correct position.

[0073] 10. Repeated operation

[0074] Equipment Reset: After installation, the operator of the mobile crane will reset the movable seat 4 to its initial position to prepare for the installation of the next corrugated steel plate. The boom will be retracted to its shortest length and lowered to its lowest position. The self-locking spring pin 5 will be released, allowing the movable seat 4 to descend freely.

[0075] Cyclic installation: Following steps S1 to S8 above, repeat the installation of the next corrugated steel sheet until the entire reinforcement project is completed. During the cyclical installation process, continuously summarize experiences, optimize operating procedures, and improve installation efficiency and quality.
