Description

Technical Field

[0001] The present invention relates to the technical field of track slab production and manufacturing, and in particular to a steel cage hoisting device and a track slab production line. Background Art

[0002] With the continuous development and improvement of high-speed railway construction technology, track slabs, as a core component of ballastless track systems, are subject to increasingly stringent manufacturing precision requirements. During track slab production, the precise installation of the steel cage is crucial for ensuring track slab quality. To meet these high-precision manufacturing requirements, deviation control technology during track slab steel cage installation has evolved from manual measurement and adjustment, to mechanically assisted positioning, to automated precision control. Early adjustments to the steel cage position relied primarily on manual experience and simple measuring tools. As manufacturing precision requirements increased, mechanized angle adjustment devices and position control systems gradually developed, and continue to evolve towards intelligent, automated precision control.

[0003] Currently, the installation of track slab reinforcement cages primarily involves using hoisting equipment to place the cages within the casting mold. The cages' horizontal deviation angles are then fine-tuned manually using simple adjustment mechanisms. Existing deviation control techniques typically involve using a level or laser measuring device to detect the cage's horizontal deviation angles, manually adjusting the cage's angles or applying force, and repeatedly measuring and verifying until the required accuracy is achieved. This entire adjustment process requires multiple cycles of measurement, adjustment, and verification to ensure the cage's final position within the mold meets the technical standards for track slab manufacturing.

[0004] Research has found that existing technologies usually require manual intervention when fine-tuning the steel cage to ultimately achieve fine-tuning of the steel cage.

[0044] With the continuous development and improvement of high-speed railway construction technology, track slabs, as a core component of ballastless track systems, are subject to increasingly stringent manufacturing precision requirements. During track slab production, the precise installation of the steel cage is crucial for ensuring track slab quality. To meet these high-precision manufacturing requirements, deviation control technology during track slab steel cage installation has evolved from manual measurement and adjustment, to mechanically assisted positioning, to automated precision control. Early adjustments to the steel cage position relied primarily on manual experience and simple measuring tools. As manufacturing precision requirements increased, mechanized angle adjustment devices and position control systems gradually developed, and continue to evolve towards intelligent, automated precision control.

[0045] Currently, the installation of track slab reinforcement cages primarily involves using hoisting equipment to place the cages within the casting mold. The cages' horizontal deviation angles are then fine-tuned manually using simple adjustment mechanisms. Existing deviation control techniques typically involve using a level or laser measuring device to detect the cage's horizontal deviation angles, manually adjusting the cage's angles or applying force, and repeatedly measuring and verifying until the required accuracy is achieved. This entire adjustment process requires multiple cycles of measurement, adjustment, and verification to ensure the cage's final position within the mold meets the technical standards for track slab manufacturing.

[0046] After research, the applicant found that the existing technology usually requires manual intervention when fine-tuning the steel cage, and finally achieves fine-tuning of the steel cage. Although this method can ultimately achieve fine-tuning of the steel cage, the manual intervention will affect the adjustment accuracy of the steel cage, and will also limit the production efficiency of the track plate.

[0047] The present invention provides a steel cage hoisting device and a track plate production line.

[0048] See also Figures 1 to 7For ease of understanding, the steel cage 200 lifting device includes:

[0049] The truss 100 has a hoisting and transfer passage 130 formed therein and extending along a first horizontal direction. A feeding position 110 and a discharging position 120 are formed at both ends of the hoisting and transfer passage 130 along the first horizontal direction. A steel cage 200 is placed on the feeding position 110. A walking passage 140 extending along the first horizontal direction is formed on the top of the truss 100. A traveling overhead crane 300 is provided on the walking passage 140 and can travel on the walking passage 140 along the first horizontal direction.

[0050] Angle adjustment mechanism 500, which is located below the traveling crane 300. The angle adjustment mechanism 500 is connected to the traveling crane 300 via a steel rope 400. The traveling crane 300 can drive the steel rope 400 to move the angle adjustment mechanism 500 up and down; and

[0051] The clamping member 600 is installed below the angle adjustment mechanism 500. The clamping member 600 can clamp the steel cage 200 placed at the feeding position 110 when the angle adjustment mechanism 500 is lowered, and transfer the steel cage 200 along the hoisting transfer channel 130 and place it at the discharge position 120.

[0052] The angle adjustment mechanism 500 is used to drive the clamping component 600 to adjust the horizontal angle of the steel cage 200.

[0053] Specifically, the truss 100 is in the form of a steel structure frame. A feeding position 110 and a discharging position 120 are arranged at intervals along the first horizontal direction (horizontal direction) within the truss 100. The feeding position 110 is located at one end of the truss 100 and is used to place the steel cage 200 to be transported. The discharging position 120 is located at the other end of the truss 100 and is used to receive the steel cage 200 after transport. The space between the feeding position 110 and the discharging position 120 forms a hoisting and transporting channel 130, which provides sufficient space for the transport of the steel cage 200. The top of the truss 100 extends along the first horizontal direction to form a walking channel 140. The walking channel 140 adopts a track structure. The traveling overhead crane 300 is arranged on the walking channel 140. The traveling overhead crane 300 cooperates with the track through the wheel set and can move smoothly on the walking channel 140 along the first horizontal direction. The angle adjustment mechanism 500 is suspended below the traveling overhead crane 300 and connected to the lifting device of the traveling overhead crane 300 via a steel rope 400. The lifting device of the traveling overhead crane 300 drives the steel rope 400 to retract and extend, driving the angle adjustment mechanism 500 to move vertically up and down. A gripping component 600 is fixedly mounted at the bottom of the angle adjustment mechanism 500. When the angle adjustment mechanism 500 descends above the feeding position 110, the gripping component 600 can grip the steel cage 200 placed at the feeding position 110. The traveling overhead crane 300 then moves along the traveling channel 140 and transfers the steel cage 200 along the hoisting and transfer channel 130 to above the discharge position 120. Finally, the angle adjustment mechanism 500 descends and places the steel cage 200 at the discharge position 120.

[0054] The steel cage hoisting device 10 of the present application realizes the automated transportation process of the steel cage 200 from the feeding position 110 to the discharging position 120 through the coordinated cooperation of the truss 100, the traveling crane 300, the angle adjustment mechanism 500 and the clamping component 600. The truss 100 provides a stable support structure for the entire hoisting system, and the hoisting transfer channel 130 formed therein ensures the smooth transportation path of the steel cage 200. The movement of the traveling crane 300 on the traveling channel 140 provides power for the horizontal transportation of the steel cage 200, and the angle adjustment mechanism 500 connected by the steel rope 400 realizes the vertical lifting and lowering of the steel cage 200, and the clamping component 600 is responsible for the grabbing and releasing operations of the steel cage 200. The entire transportation process does not require direct human participation, which significantly improves the degree of automation and operating efficiency of the transportation of the steel cage 200.

[0055] When the clamping component 600 places the steel cage 200 at the discharge position 120, the angle adjustment mechanism 500 can drive the clamping component 600 to adjust the horizontal angle of the steel cage 200. Specifically, the angle adjustment mechanism 500 includes a rotary drive device and an angle sensor. The rotary drive device can accurately control the rotation angle of the clamping component 600 around the vertical axis through a drive system composed of a servo motor and a reducer. The angle sensor detects the current horizontal angle of the steel cage 200 in real time and feeds back the angle information to the control system. After the steel cage 200 is placed at the discharge position 120, the control system drives the rotary drive device to adjust the angle of the clamping component 600 according to the deviation between the preset target angle and the current angle, thereby achieving precise adjustment of the horizontal angle of the steel cage 200. During the adjustment process, the angle sensor continuously monitors the angle change. When the target angle is reached, the rotary drive device stops moving, completing the angle adjustment operation.

[0056] The steel cage hoisting device 10 of the present application uses an automated angle adjustment mechanism 500 to replace the traditional manual fine-tuning method, fundamentally eliminating the adverse effects of manual operation on adjustment accuracy. The angle adjustment mechanism 500 achieves accurate and rapid adjustment of the angle of the steel cage 200 through precise sensor detection and servo drive control. The automation of the entire hoisting, transportation and angle adjustment process not only ensures the high-precision requirements for the installation of the steel cage 200, but also significantly improves the overall operating efficiency of the track plate production line, providing reliable technical support for the large-scale, high-quality production of track plates.

[0057] In this embodiment, by providing a truss 100, an angle adjustment mechanism 500, and a clamping component 600, when in use, a feeding position 110 and a discharging position 120 are formed in the truss 100 at intervals along the first horizontal direction, and a hoisting and transfer channel 130 is formed between the feeding position 110 and the discharging position 120. At the same time, a walking channel 140 is provided on the top of the truss 100, and a traveling crane 300 is installed on the walking channel 140 so that the traveling crane 300 can travel on the walking channel 140 along the first horizontal direction. Then, the angle adjustment mechanism 500 is installed on the traveling crane 300. , and at the same time, the clamping component 600 is installed below the angle adjustment mechanism 500, so that the angle adjustment mechanism 500 can drive the clamping component 600 to rotate, so that when the clamping component 600 places the steel cage 200 at the discharge position 120, the horizontal angle of the clamping component 600 and the steel cage 200 clamped by the clamping component 600 can be adjusted, and thus there is no need to manually adjust the horizontal deviation of the steel cage 200, and the function of adjusting the angle of the steel cage 200 when hoisting and transporting the steel cage 200 is realized, which can ensure the installation accuracy of the steel cage 200 and the production efficiency of the track plate.

[0058] In one embodiment, the angle adjustment mechanism 500 includes:

[0059] Base 510, base 510 is connected to the steel rope 400;

[0060] An angle adjustment assembly 520 , which is mounted on the bottom of the base 510 , and an output shaft of the angle adjustment assembly 520 extends vertically downward; and

[0061] The connecting frame 530 is installed on the output shaft of the angle adjustment component 520. The bottom of the connecting frame 530 is connected to the clamping component 600. The angle adjustment component 520 can drive the connecting frame 530 to drive the clamping component 600 to rotate to adjust the horizontal angle of the steel cage 200 clamped on the clamping component 600.

[0062] On this basis, the base 510 serves as the main bearing structure of the angle adjustment mechanism 500. A steel rope 400 connection device is provided on its top. The steel rope 400 connection device includes a connecting ring and a locking bolt. The steel rope 400 is reliably connected to the base 510 through the connecting ring, and the locking bolt ensures the stability of the connection. The base 510 is made of high-strength aluminum alloy material, has good load-bearing capacity and anti-deformation performance, and can withstand the weight of the steel cage 200 and the torque generated during rotation. The angle adjustment assembly 520 is installed at the bottom of the base 510 and is fixed to the base 510 by bolt connection. The angle adjustment assembly 520 includes a servo motor, a reducer and an angle encoder. The servo motor provides rotational power, the reducer converts the high-speed rotation of the motor into a low-speed, high-torque output, and the angle encoder monitors the rotation angle of the output shaft in real time.

[0063] The output shaft of the angle adjustment assembly 520 extends vertically downward. The output shaft adopts a hollow shaft structure and is provided with a signal transmission cable inside for transmitting control signals and feedback signals. A flange is provided at the lower end of the output shaft, and the connecting frame 530 is connected to the output shaft via the flange. The connecting frame 530 adopts a frame structure, including an upper connecting plate, a lower connecting plate and a connecting column. The upper connecting plate is connected to the output shaft flange of the angle adjustment assembly 520, and the lower connecting plate is connected to the top of the clamping component 600. The connecting column connects the upper and lower connecting plates into an integral frame structure. A clamping component 600 mounting interface is provided at the bottom of the connecting frame 530, and the clamping component 600 is fixed to the bottom of the connecting frame 530 by bolt connection. When the servo motor of the angle adjustment assembly 520 is started, the motor rotation is transmitted to the output shaft through the reducer, and the output shaft drives the connecting frame 530 to rotate around the vertical axis. The connecting frame 530 then drives the clamping component 600 installed at its bottom to rotate synchronously, thereby realizing the horizontal angle adjustment of the steel cage 200 clamped on the clamping component 600.

[0064] In one embodiment, a sliding ring 540 is formed on the base 510, and the sliding ring 540 is arranged around the outer periphery of the angle adjustment assembly 520. A sliding column 550 that slides with the sliding ring 540 is provided at the top of the connecting frame 530, and the top of the sliding column 550 extends upward from the sliding ring 540 to form an anti-slip portion.

[0065] Specifically, an annular sliding ring 540 is formed on the base 510. Made of wear-resistant material, it features a smooth inner surface. It surrounds the outer circumference of the angle adjustment assembly 520, maintaining a certain clearance therebetween. The annular sliding ring 540 is fixed to the bottom of the base 510 and coaxial with the angle adjustment assembly 520. Its inner diameter is slightly larger than the outer diameter of the angle adjustment assembly 520, forming an annular sliding channel. The inner surface of the sliding ring 540 is precision-machined to a surface roughness of Ra0.8 or less, ensuring smoothness and minimizing frictional resistance.

[0066] A sliding column 550 is provided at the top of the connecting frame 530. The sliding column 550 and the connecting frame 530 are an integral structure and are firmly fixed to the top of the connecting frame 530 by welding or bolting. The sliding column 550 is cylindrical, and its outer diameter is slightly smaller than the inner diameter of the sliding ring 540, forming a sliding fit relationship. The fitting clearance between the sliding column 550 and the sliding ring 540 is controlled within the range of 0.5-1mm, which ensures that the sliding column 550 can rotate freely in the sliding ring 540 and prevents excessive clearance from causing the connecting frame 530 to shake. The sliding column 550 is made of high-strength nylon or polytetrafluoroethylene material, which has excellent self-lubrication and wear resistance, can reduce the friction resistance between it and the sliding ring 540, and extend its service life. The sliding ring 540 extends upward from the top of the sliding column 550, and forms an anti-slip portion with a diameter larger than the inner diameter of the sliding ring 540. The anti-slip portion is disc-shaped, and its diameter is 10-15 mm larger than the inner diameter of the sliding ring 540 , forming an effective anti-slip structure to ensure that the sliding column 550 will not slip out of the sliding ring 540 when the connecting frame 530 is subjected to external force.

[0067] The present application constructs an auxiliary support and guide structure by forming a sliding ring 540 on the base 510 and setting a sliding column 550 that slides with the sliding ring 540 on the top of the connecting frame 530. When the output shaft of the angle adjustment assembly 520 drives the connecting frame 530 to rotate, the sliding column 550 on the top of the connecting frame 530 slides in the sliding ring 540 to form a stable rotation guide, preventing the connecting frame 530 from generating radial shaking and axial displacement during the rotation process. The anti-slip portion on the top of the sliding column 550 ensures a reliable connection between the connecting frame 530 and the base 510, preventing the connecting frame 530 from separating from the base 510 due to load changes or external force interference, thereby improving the stability and safety of the entire angle adjustment mechanism 500.

[0068] In actual application, when the weight of the steel cage 200 is large or the shape is irregular, resulting in a shift in the center of gravity, it is easy for the connecting frame 530 to generate lateral force and overturning moment. The matching structure of the sliding column 550 and the sliding ring 540 can effectively resist these adverse factors and ensure that the connecting frame 530 always maintains a stable rotation state. At the same time, the sliding fit between the sliding column 550 and the sliding ring 540 reduces the radial load on the output shaft of the angle adjustment assembly 520 and extends the service life of the angle adjustment assembly 520. The presence of the anti-slip portion further enhances the safety and reliability of the system. Even in extreme cases, if the output shaft of the angle adjustment assembly 520 fails, the matching structure of the sliding column 550 and the sliding ring 540 can temporarily support the connecting frame 530 and the clamping component 600, preventing the steel cage 200 from accidentally falling, thereby improving the safety of the entire lifting system.

[0069] In another embodiment, the sliding post 550 and the sliding ring 540 utilize a rolling bearing arrangement. Specifically, multiple balls or needles are positioned around the periphery of the sliding post 550. These rolling elements contact the inner wall of the sliding ring 540, converting sliding friction into rolling friction. This further reduces rotational resistance and improves the sensitivity and precision of angle adjustment. Furthermore, this rolling bearing arrangement can withstand greater radial loads, making it suitable for handling large, heavy rebar cages 200. The anti-slip feature on the top of the sliding post 550 is removable, facilitating maintenance and replacement of the rolling elements and extending the service life of the entire arrangement.

[0070] In one embodiment, there are multiple sliding posts 550 , and the multiple sliding posts 550 are distributed in the sliding ring 540 at intervals along the circumferential direction.

[0071] Specifically, the sliding ring 540 adopts an annular structure, whose inner diameter forms an annular space to accommodate the sliding posts 550. Multiple sliding posts 550 are distributed along the circumference of the sliding ring 540 at predetermined angular intervals. In a preferred embodiment, four sliding posts 550 are provided within the sliding ring 540, distributed at 90-degree intervals along the circumference to form a symmetrical four-point support structure. Each sliding post 550 is manufactured from high-strength stainless steel, and its surface is precision-ground to ensure a good sliding fit between the sliding post 550 and the inner wall of the sliding ring 540. One end of the sliding post 550 is fixedly connected to the output shaft of the angle adjustment assembly 520, while the other end slides radially within the sliding ring 540. When the angle adjustment assembly 520 drives the output shaft to rotate, the sliding post 550 rotates synchronously with the output shaft while sliding relative to it within the sliding ring 540.

[0072] The circumferentially spaced arrangement of multiple sliding posts 550 provides stable support and guidance during angle adjustment. The inner wall of the sliding ring 540 is provided with guide grooves corresponding to the number of sliding posts 550. Each guide groove extends radially along the sliding ring 540, and the sliding posts 550 slide radially within the guide grooves. The width of the guide grooves is slightly larger than the diameter of the sliding posts 550, ensuring that the sliding posts 550 can slide freely within the guide grooves while preventing wobbling caused by excessive clearance. A lubrication device is provided between the sliding posts 550 and the guide grooves. The lubrication device includes a grease injection port and a sealing ring. Grease is regularly replenished through the injection port, and the sealing ring prevents grease leakage and the ingress of external impurities. When the clamping component 600 clamps the rebar cage 200 and angle adjustment is required, the output shaft of the angle adjustment assembly 520 drives the sliding posts 550 to rotate. The sliding posts 550 slide within the guide grooves of the sliding ring 540, achieving angle adjustment of the connecting frame 530 relative to the base 510.

[0073] The present application significantly improves the stability and load-bearing capacity of the angle adjustment mechanism 500 by configuring a plurality of sliding columns 550 with circumferential spacing. Compared with the configuration of a single sliding column 550, the plurality of sliding columns 550 can evenly distribute the weight of the steel cage 200 and the torque generated during the adjustment process to each sliding column 550, avoiding deformation or damage caused by excessive force on a single point. The symmetrical distribution of the four sliding columns 550 forms a stable four-point support structure, which effectively suppresses the swing or vibration that may occur during the angle adjustment process, and ensures the smoothness and accuracy of the angle adjustment of the steel cage 200. The configuration of multiple sliding columns 550 also improves the redundancy of the system. Even if one of the sliding columns 550 fails, the remaining sliding columns 550 can still maintain the basic functions of the system, thereby improving the reliability and safety of the equipment.

[0074] In some preferred embodiments, six sliding columns 550 are provided in the sliding ring 540, and the six sliding columns 550 are distributed every 60 degrees along the circumference to form a six-point support structure. The configuration of the six sliding columns 550 further enhances the load-bearing capacity and stability of the angle adjustment mechanism 500, and is particularly suitable for the hoisting operation of a large steel cage 200. The diameter of each sliding column 550 is reduced accordingly. Under the premise of ensuring the total load-bearing area, the friction resistance between a single sliding column 550 and the guide groove is reduced, thereby improving the sensitivity and response speed of the angle adjustment. The six-point support structure has better symmetry, can more effectively suppress the unbalanced torque during the angle adjustment process, and further improve the accuracy of the angle adjustment of the steel cage 200.

[0075] In one embodiment, the angle adjustment assembly 520 includes:

[0076] A first drive motor 521 is mounted on the base 510 , and an output shaft of the first drive motor 521 extends vertically downward; and

[0077] The connecting sleeve 522 is installed on the top of the connecting frame 530 and is connected to the output shaft of the first driving motor 521 .

[0078] Specifically, the first drive motor 521 serves as the core power source of the angle adjustment assembly 520 and is installed on the bottom platform of the base 510. The first drive motor 521 adopts a servo motor structure and has high-precision position control and torque output capabilities. The first drive motor 521 is fixed to the mounting base of the base 510 by bolts. The mounting base is provided with a vibration-damping gasket to effectively isolate the vibration generated during the operation of the motor. The output shaft of the first drive motor 521 adopts a hollow shaft structure and extends downward in the vertical direction. The outer surface of the output shaft is precisely machined and the surface roughness reaches Ra0.8μm, ensuring the matching accuracy with the connecting sleeve 522. A signal transmission channel is provided inside the output shaft for transmitting control signals and feedback signals to avoid the influence of external cable entanglement on angle adjustment.

[0079] The connecting sleeve 522 is mounted at the top center of the connecting frame 530. Made of high-strength alloy steel, its inner bore is precision-bored to form an H7 / H6 fit with the output shaft of the first drive motor 521, ensuring tight connection and transmission accuracy. A keyway is provided on the outer surface of the connecting sleeve 522, and a corresponding key is provided on the top of the connecting frame 530. This key connection secures the connecting sleeve 522 to the connecting frame 530, preventing relative rotation. A spline connection is employed between the connecting sleeve 522 and the output shaft of the first drive motor 521, providing excellent torque transmission and axial positioning accuracy. When the first drive motor 521 is activated, the motor's rotational motion is transmitted to the connecting sleeve 522 via the output shaft. The connecting sleeve 522, in turn, rotates the connecting frame 530 about its vertical axis, enabling angular adjustment of the clamping component 600 and the steel cage 200 it clamps.

[0080] The angle adjustment assembly 520 of the present application realizes efficient and reliable power transmission through the direct connection configuration of the first drive motor 521 and the connecting sleeve 522. The first drive motor 521 is installed on the base 510 to provide a stable power source for angle adjustment, and the servo control system of the motor can achieve precise angle positioning and speed control. The connecting sleeve 522 serves as a transmission interface between the first drive motor 521 and the connecting frame 530, directly transmitting the rotational motion of the motor to the connecting frame 530, avoiding complex transmission devices, reducing transmission errors and mechanical clearances. The vertical downward extension configuration of the output shaft of the first drive motor 521 makes the structure of the entire angle adjustment mechanism 500 compact, the center of gravity position is reasonable, and the stability of the system is improved. The precise fit between the connecting sleeve 522 and the output shaft ensures the reliability and accuracy of the transmission, and can fully transmit the control accuracy of the first drive motor 521 to the angle adjustment process of the steel cage 200.

[0081] In one embodiment, the angle adjustment assembly 520 further includes a plurality of displacement sensors 523 . The plurality of displacement sensors 523 are circumferentially spaced and distributed at the bottom of the connection frame 530 , and each displacement sensor 523 is disposed downward.

[0082] Specifically, the displacement sensor 523, as an important supplement to the angle adjustment assembly 520, is mounted around the bottom of the connecting frame 530. Specifically, the bottom of the connecting frame 530 is provided with multiple sensor mounting brackets, evenly distributed along the circumference of the connecting frame 530, with a displacement sensor 523 fixedly mounted on each bracket. The displacement sensor 523 utilizes a high-precision laser displacement sensor with a measurement accuracy of ±0.01mm and a measurement range of 0-200mm. The detection end of the displacement sensor 523 is positioned downward, and the detection beam is projected vertically downward to measure the change in distance between the sensor and the surface of the object being measured.

[0083] A plurality of displacement sensors 523 are distributed circumferentially at the bottom of the connecting frame 530 to form a measurement array. In a preferred embodiment, four displacement sensors 523 are installed at the bottom of the connecting frame 530, and the four displacement sensors 523 are evenly distributed every 90 degrees along the circumferential direction to form a square measurement array. Each displacement sensor 523 is connected to the connecting frame 530 through a shock-proof connector. The shock-proof connector includes a rubber shock-absorbing pad and a precision adjustment screw. The rubber shock-absorbing pad can effectively absorb the vibration generated during the operation of the system. The precision adjustment screw is used to adjust the installation height and angle of the displacement sensor 523 to ensure the accurate projection of the measurement beam. The displacement sensor 523 is connected to the control system through a shielded signal line. The signal line is made of highly flexible material and can adapt to the rotational movement of the connecting frame 530 without breaking or interference.

[0084] This application achieves real-time and accurate measurement of the position and posture of the rebar cage 200 by installing multiple downwardly positioned displacement sensors 523 circumferentially around the bottom of the connecting frame 530. When the angle adjustment assembly 520 drives the connecting frame 530 to rotate, the displacement sensors 523 rotate with the connecting frame 530, continuously monitoring distance changes on the surface of the rebar cage 200. By analyzing the measurement data from the multiple displacement sensors 523, the control system can calculate the actual position, angle, and posture of the rebar cage 200. For example, when the rebar cage 200 is horizontal, the measurement values ​​of the four displacement sensors 523 should be essentially consistent. If the rebar cage 200 is tilted, the displacement sensors 523 at different locations will measure different distance values. These differences can be used to calculate the tilt angle and direction of the rebar cage 200. Based on this real-time measurement data, the control system precisely controls the operating parameters of the drive motor, achieving closed-loop control adjustment of the angle of the rebar cage 200.

[0085] In one embodiment, the clamping member 600 includes:

[0086] A mounting plate 610, the mounting plate 610 is mounted on the angle adjustment mechanism 500, and the bottom of the mounting plate 610 is provided with two pin holes spaced apart along a first horizontal direction;

[0087] Two clamping plates 620 are arranged side by side and are rotatably inserted into two pin holes by pins, so that the two clamping plates 620 are hinged to the mounting plate 610. The two clamping plates 620 can rotate around the corresponding pins. The opposite sides of the two clamping plates 620 are recessed to form a receiving groove. The receiving grooves on the two clamping plates 620 can be connected in pairs to form a receiving hole for accommodating the main bars of the steel cage, and the end of each clamping plate 620 away from the mounting plate 610 forms a pointed end; and

[0088] The elastic reset member 630 is connected between the two clamping plates 620 , and the elastic reset member 630 enables the two clamping plates 620 to clamp the main reinforcement.

[0089] Specifically, the mounting plate 610 serves as the main supporting structure of the clamping component 600. A mounting interface that cooperates with the bottom of the connecting frame 530 is provided on its top and is fixed to the connecting frame 530 by bolt connection. The mounting plate 610 is made of high-strength aluminum alloy material and has a good strength-to-weight ratio and corrosion resistance. Two pin holes are provided at the bottom of the mounting plate 610 along the third direction (horizontally). The center distance between the two pin holes is determined according to the spacing of the main reinforcements of the steel cage 200, usually 200-300mm. The pin holes are processed by precision drilling, and the hole diameter tolerance is controlled within the range of ±0.02mm to ensure the matching accuracy of the pins. The two clamping plates 620 are riveted to the corresponding pin holes through pins respectively. The pins are made of stainless steel material, and the surface is hardened and has good wear resistance and shear strength.

[0090] The two clamping plates 620 are arranged side by side at the bottom of the mounting plate 610. Each clamping plate 620 can rotate around the corresponding pin, and the rotation angle range is 0-45 degrees, which meets the clamping requirements of the main bars of the steel cage 200 with different diameters. The clamping plate 620 is made of high-strength alloy steel material, and the surface is rust-proofed and has good durability. The inner sides of the two clamping plates 620 that are relatively set are recessed to form a receiving groove. The receiving groove is in the shape of a semicircular arc, and the radius of the arc is determined according to the diameter of the main bar, usually 15-25mm. When the receiving grooves on the two clamping plates 620 are relatively set, a complete circular receiving hole is formed. The diameter of the receiving hole matches the diameter of the main bar of the steel cage 200, ensuring that the main bar can be firmly accommodated in the receiving hole. Each clamping plate 620 has a tip structure formed at one end away from the mounting plate 610, with a tip angle of 30-45 degrees. The sharp shape of the tip facilitates the insertion of the clamping plate 620 into the gap between the steel bars of the steel cage 200, thereby achieving accurate positioning and clamping of the main bars.

[0091] The elastic reset member 630 is installed between the two clamping plates 620. The elastic reset member 630 utilizes a compression spring structure, with one end of the spring connected to the first clamping plate 620 and the other end connected to the second clamping plate 620. The elastic reset member 630 provides a continuous compressive force, keeping the two clamping plates 620 clamped inward at all times, ensuring that the main reinforcement is securely clamped within the receiving hole. The spring constant is determined based on the weight of the main reinforcement in the steel cage 200 and the required clamping force, typically providing a clamping force of 50-100N. When the main reinforcement needs to be clamped, an external drive device overcomes the elastic force of the elastic reset member 630, causing the two clamping plates 620 to open outward, expanding the receiving hole to accommodate the main reinforcement. The external drive force is then released, and the elastic force of the elastic reset member 630 resets the clamping plates 620 to clamp the main reinforcement. When the main reinforcement needs to be released, the external drive device again opens the clamping plates 620, releasing the main reinforcement from the receiving hole.

[0092] In one embodiment, two arc-shaped gear rings 640 meshing with each other are formed on one end of the two clamping plates 620 close to the mounting plate 610 .

[0093] Specifically, the arc-shaped toothed rings 640 on the two clamping plates 620 mesh with each other. When the first clamping plate 620 rotates around the pin, its arc-shaped toothed ring 640 drives the arc-shaped toothed ring 640 on the second clamping plate 620 to rotate synchronously, thereby achieving synchronous movement of the two clamping plates 620. The meshing transmission of the arc-shaped toothed rings 640 ensures that the rotation angles of the two clamping plates 620 always remain consistent, and the rotation angle error is controlled within the range of ±0.5 degrees. When the external drive device drives the first clamping plate 620 to open outward, the arc-shaped toothed ring 640 of the first clamping plate 620 simultaneously drives the second clamping plate 620 to open outward through the meshing action, and the receiving grooves of the two clamping plates 620 are separated synchronously, and the receiving holes are expanded to accommodate the main bars of the steel cage 200. When the external driving force is released, the elastic force of the elastic reset member 630 causes the first clamping plate 620 to rotate inward, and the meshing transmission of the arc-shaped gear ring 640 ensures that the second clamping plate 620 rotates inward synchronously. The two receiving grooves close together to form a complete receiving hole, thereby clamping the main reinforcement.

[0094] The present application realizes the precise synchronous movement of the two clamping plates 620 through the meshing transmission configuration of the arc-shaped gear ring 640. The meshing transmission of the arc-shaped gear ring 640 eliminates the asynchronism that may be caused by the independent movement of the two clamping plates 620, ensuring the symmetry of the receiving hole and the uniform distribution of the clamping force. The forced synchronization effect of the gear ring meshing avoids the influence of the stagnation or slow movement of the single-sided clamping plate 620 on the clamping effect, and improves the reliability and consistency of the clamping operation. The involute tooth profile of the arc-shaped gear ring 640 provides a smooth transmission characteristic, reduces the impact and vibration during the transmission process, and extends the service life of the clamping plate 620. The hardening treatment of the gear ring surface ensures that the transmission accuracy is maintained during long-term use, and avoids the decrease in synchronization accuracy due to wear.

[0095] In one embodiment, one of the clamping plates 620 is fixed to a corresponding pin, and the clamping component also includes a second drive motor 650, which is installed on a mounting seat. The output shaft of the second drive motor 650 is connected to the pin fixed to the corresponding clamping plate 620 to drive the corresponding clamping plate 620 to rotate open and lower the steel cage 200.

[0096] Specifically, when the second drive motor 650 is activated, its output shaft rotates the drive shaft through a coupling, which in turn drives the first clamping plate 620 to rotate about the pin. Because the two clamping plates 620 are formed with intermeshing arcuate toothed rings 640 at one end near the mounting plate 610, the rotation of the first clamping plate 620, through the meshing transmission of the arcuate toothed rings 640, drives the second clamping plate 620 to rotate synchronously. Both clamping plates 620 open outward simultaneously, expanding the receiving holes to release the main bars of the rebar cage 200. Once the rebar cage 200 is lowered into place, the second drive motor 650 rotates in the opposite direction, driving the two clamping plates 620 to close inward and re-clamp the main bars of the rebar cage 200. The precise control of the second drive motor 650 allows the opening and closing angles of the clamping plates 620 to be adjusted to accommodate the different diameters of the main bars of the rebar cage 200, thus meeting the requirements for clamping rebar cages 200 of varying specifications.

[0097] Based on the same technical concept, in a second aspect, the present invention further proposes a track plate production line, comprising:

[0098] The reinforcement cage hoisting device 10 of the first aspect; and

[0099] The track slab casting and forming mechanism 20 has a track slab casting and forming space formed therein. The track slab casting and forming mechanism 20 is installed at the discharge position 120. The steel cage hoisting device 10 can clamp the steel cage 200 at the feeding position 110 and transfer the steel cage 200 along the hoisting transfer channel 130 and place it in the track slab casting and forming space to form the track slab after pouring concrete in the casting and forming space.

[0100] Specifically, the rebar cage hoisting device 10 is responsible for lifting the rebar cage 200 from its storage location and moving it to the feeding position 110, ensuring that the rebar cage 200 remains stable during the pouring process. The track slab casting and forming mechanism 20 serves as the primary area for concrete pouring, its interior space housing the rebar cage 200 and performing the concrete pouring. A pouring port is located at the bottom of the mechanism, connected to a concrete delivery pipeline, ensuring smooth concrete pouring into the rebar cage 200.

[0101] The function of the transfer mechanism is to transfer the steel cage 200 from the feeding position 110 to the track slab casting and molding space. The transfer mechanism includes a clamping component 600 and a moving device. The clamping component 600 is capable of clamping the steel cage 200 at the feeding position 110, and the moving device is responsible for moving the clamped steel cage 200 along the transfer channel to the casting and molding space. The moving device adopts an electric drive system, which can achieve smooth movement and precise positioning. The design of the clamping component 600 ensures that the steel cage 200 will not be damaged during the clamping and placement process, and the clamping force can be adjusted to accommodate steel cages 200 of different specifications.

[0102] Within the casting and molding space, a steel cage 200 is fixed in a predetermined position. Concrete is evenly poured into the cage 200 through the pouring port, forming the track slab's foundation structure. After pouring, a vibration device is installed at the bottom of the track slab casting and molding mechanism 20 to vibrate the poured concrete, ensuring its density and strength. The vibration device's frequency and amplitude are adjustable to accommodate different concrete formulations.

[0103] The track slab production line of the present application effectively solves the problems of low track slab production efficiency and complex operation in the prior art through the coordinated operation of the steel cage hoisting device 10, the track slab casting and forming mechanism 20, and the transfer mechanism. The stability and reliability of the steel cage hoisting device 10 ensure the safety of the steel cage 200 throughout the production process, avoiding damage to the steel cage 200 due to improper hoisting. The specialized design of the track slab casting and forming mechanism 20 makes the concrete pouring process more efficient, reducing the pouring time from the traditional 30 minutes to less than 10 minutes, significantly improving production efficiency.
