Description

A track slab laying fine-tuning trolley Technical Field

[0001] This invention belongs to the technical field of track slab paving fine-tuning equipment, and particularly relates to a track slab paving fine-tuning trolley. Background Technology

[0002] As train speeds increase, the requirements for railway subgrade become increasingly stringent, especially at speeds of 200 km / h or higher. Traditional graded crushed stone track beds are often insufficient to meet these demands. Precast concrete track beds, however, can now meet the subgrade requirements for high-speed train operation.

[0003] Precast concrete track slabs are used for paving operations, which involve hoisting and installing them onto the roadbed to achieve the purpose of laying a complete track bed. Currently, track slabs are installed using gantry cranes and manual labor.

[0004] However, the above method requires a large number of people to lift, pry, move, and support the track slabs using simple tools, which is inefficient. The movement of personnel, moving back and forth with the gantry crane, is extremely strenuous, and there are risks of collisions, crushing injuries, or pinching injuries to personnel near the track slabs. Furthermore, fine-tuning of the track slabs is required after installation, which is quite troublesome. Summary of the Invention

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] As shown in Figures 1-17, the present invention provides a technical solution: a track slab paving fine-tuning trolley, comprising a support frame 1, a gripping mechanism 2 disposed on the support frame 1, a plurality of fine-tuning claws 6 disposed around the track slab, a turning mechanism 7 disposed on the gripping mechanism 2 for adjusting the fine-tuning claws 6, a traveling mechanism 3 disposed at the bottom of the support frame 1, and a control box 4 disposed on the side of the support frame 1, wherein the control box 4 is provided with a control module; the fine-tuning claw 6 comprises an adjuster base 6-1, a vertical adjusting screw 6-2, a horizontal adjusting screw 6-3, and a steering mechanism 6-4; the vertical adjusting screw 6-2 is connected to the adjuster base 6-1. The vertical adjusting screw 6-2 is vertically positioned on the base 6-1 of the regulator. Rotating the vertical adjusting screw 6-2 causes it to move up and down. The side of the vertical adjusting screw 6-2 is connected to a fixed connecting plate 6-5, which is used to connect to the track slab. The horizontal adjusting screw 6-3 and the vertical adjusting screw 6-2 are positioned in the same direction and are also perpendicular to the base 6-1 of the regulator. The horizontal adjusting screw 6-3 is connected to a steering mechanism 6-4, which is located on the upper part of the base 6-1 of the regulator, converting the vertical rotational force of the horizontal adjusting screw 6-3 into a horizontal rotational force. The regulator base 6-1 is placed on the ballastless track base and connected to the side of the track slab. The support frame 1 includes two symmetrically arranged side frames 1-1 and a crossbeam 1-2 connecting the two side frames 1-1 and horizontally spanning above two railway tracks. The traveling mechanism 3 is located at the bottom of the side frames 1-1 to drive the support frame 1 to move along the railway tracks. The gripping mechanism 2 includes a top support 2-1, a lifting drive mechanism 2-2, an opening and closing drive mechanism 2-3, and a gripper 2-4. The top support 2-1 is slidably connected to the crossbeam 1-2. A translation drive mechanism 5 is provided between the crossbeam 1-2 and the top support 2-1 to drive the top support 2-1 to slide along the crossbeam 1-2. The lifting drive mechanism 2-2 is connected to... The top support 2-1 is used to drive the opening and closing drive mechanism 2-3 to move up and down. The opening and closing drive mechanism 2-3 is connected to the gripper 2-4 to drive the gripper 2-4 to open and close to grip and release the track plate. The turning mechanism 7 is connected to the bottom of the lifting drive mechanism 2-2 to turn the vertical adjusting screw 6-2 or the horizontal adjusting screw 6-3 respectively. The control module is electrically connected to the walking mechanism 3, the translation drive mechanism 5, the lifting drive mechanism 2-2, the opening and closing drive mechanism 2-3, and the turning mechanism 7 respectively to control the walking mechanism 3, the translation drive mechanism 5, the lifting drive mechanism 2-2, the opening and closing drive mechanism 2-3, and the turning mechanism 7.

[0048] During operation, the track slabs are first laid: the track slabs are vertically stacked on the railway track base. The control module controls the traveling mechanism 3 to drive the support frame 1 to move along the railway track direction, and controls the translation drive mechanism 5 to drive the top support 2-1 to move laterally perpendicular to the railway track, so that the gripping mechanism 2 moves to above the stacked track slabs. The control module controls the lifting drive mechanism 2-2 to drive the opening and closing drive mechanism 2-3 and the gripper 2-4 to move downwards until the gripper 2-4 is at the same height as the track slab to be gripped. Then, the control module controls the opening and closing drive mechanism 2-3 to drive the gripper 2-4 to close and grasp the track slab. Finally, the lifting drive mechanism... 2-2 drives the opening and closing drive mechanism 2-3 and the claw 2-4 to move upward to raise the track plate. Then, the walking mechanism 3 drives the support frame 1 to move along the railway track direction, and the translation drive mechanism 5 drives the top bracket 2-1 to move laterally perpendicular to the railway track, so that the track plate is moved directly above the railway track base where it needs to be placed. Then, the lifting drive mechanism 2-2 drives the opening and closing drive mechanism 2-3 and the claw 2-4 to move downward until the fine adjustment claws around the track plate touch the ground. Finally, the opening and closing drive mechanism 2-3 drives the claw 2-4 to open and lower the track plate, thus completing the installation of the track plate. Repeat the above steps to complete the installation of other track plates.

[0049] After the track slabs are laid, fine-tuning can be performed: the control module controls the walking mechanism 3 to drive the support frame 1 to move along the railway track direction, and controls the translation drive mechanism 5 to drive the top support 2-1 to move laterally perpendicular to the railway track, so that the turning mechanism 7 is aligned directly above the vertical adjusting screw 6-2 and the horizontal adjusting screw 6-3 of the fine-tuning claw 6. The control module controls the lifting drive mechanism 2-2 to drive the turning mechanism 7 to move downwards to connect with the vertical adjusting screw 6-2 and the horizontal adjusting screw 6-3 of the fine-tuning claw 6. Finally, the control module controls the turning mechanism 7 to turn the vertical adjusting screw 6-2 or the horizontal adjusting screw 6-3, which can simultaneously adjust the plane and elevation of the track slab without affecting each other. The horizontal adjusting screw 6-3 is used to adjust the plane of the track slab, and the vertical adjusting screw 6-2 is used to adjust the elevation of the track slab, thereby achieving fine-tuning of the position of the track slab.

[0050] In practical implementation, the control module can refer to the PLC module or the microcontroller or ARM controller.

[0051] This invention has a simple structure and reasonable design, enabling the gripping, lifting, lateral movement, longitudinal movement, and fine adjustment of track slabs. It can quickly complete the laying and fine adjustment of double-track slabs in ballastless tracks without frequent manual intervention, saving manpower and resources and improving construction efficiency.

[0052] Further, as shown in Figure 17, the steering gear 6-4 includes a steering gear assembly 6-4-1; it also includes a lateral gear 6-4-2 and a vertical gear 6-4-3 disposed inside the steering gear assembly 6-4-1. The lateral gear 6-4-2 is located directly below the lateral adjusting screw 6-3, and the bottom of the lateral adjusting screw 6-3 is fixedly connected to the lateral gear 6-4-2. Rotating the lateral adjusting screw 6-3 causes the lateral gear 6-4-2 to rotate in the horizontal direction. The vertical gear 6-4-3 meshes with the lateral gear 6-4-2, and the rotation of the lateral gear 6-4-2 causes the vertical gear 6-4-3 to rotate in the vertical direction. It also includes a lateral lead screw 6-4-4 and a sliding... The movable nut 6-4-5 and the adjuster housing 6-4-6 are connected above the adjuster base 6-1, and the sliding nut 6-4-5 is connected inside the adjuster housing 6-4-6. The transverse lead screw 6-4-4 is horizontally arranged inside the steering assembly 6-4-1. One end of the transverse lead screw 6-4-4 is threadedly connected to the sliding nut 6-4-5, and the other end is fixed to the vertical gear 6-4-3. That is, rotating the transverse lead screw 6-4-4 can drive the steering assembly 6-4-1 to move left and right relative to the sliding nut 6-4-5, thereby realizing the simultaneous fine adjustment of the track slab in the horizontal direction and the elevation direction perpendicular to the extension direction of the railway track in the vertical direction.

[0053] Furthermore, the walking mechanism 3 includes four moving wheel sets 3-1, which are respectively arranged in pairs at the bottom of the two side frames 1-1 to form a stable support for the support frame 1. As shown in Figure 3, each moving wheel set 3-1 is provided with a first servo motor 3-2 for driving the moving wheel set 3-1. The moving wheel set 3-1 includes a support housing 3-1-1 and a rubber wheel 3-1-2. The support housing 3-1-1 is connected to the bottom of the side frame 1-1, and the rubber wheel 3-1-2 is rotatably connected to the bottom of the support housing 3-1-1. The first servo motor 3-2 is connected to the support housing 3-1-1 and its output shaft is drivenly connected to the rubber wheel 3-1-2. The first servo motor 3-2 is electrically connected to the control module. During operation, the control module controls the first servo motor 3-2 to drive the rubber wheel 3-1-2 to rotate, thereby realizing the movement of the paving trolley of the present invention along the railway track direction.

[0054] Furthermore, the support housings 3-1-1 of the two moving wheel sets 3-1 located at the front of the support frame 1 in the direction of travel are rotatably connected to the bottom of the side frame 1-1, and the two support housings 3-1-1 are provided with a steering mechanism 3-3 to drive the support housings 3-1-1 to rotate relative to the side frame 1-1, so as to realize the steering of the two moving wheel sets 3-1 at the front, thereby correcting the movement of the paving trolley of the present invention along the railway track direction; specifically, as shown in Figure 3, the steering mechanism 3-3 is a first telescopic hydraulic cylinder, the two ends of the first telescopic hydraulic cylinder are respectively hinged to the bottom of the side frame 1-1 and the support housing 3-1-1, and a first solenoid valve is provided on the oil supply pipeline of the first telescopic hydraulic cylinder. The first solenoid valve is electrically connected to the control module. When working, the control module controls the opening and closing of the first solenoid valve, thereby controlling the extension and retraction of the first telescopic hydraulic cylinder, thereby adjusting the direction of the moving wheel sets 3-1.

[0055] Further, as shown in Figure 6, a slide rail 5-1 parallel to the crossbeam 1-2 is provided on the crossbeam 1-2, and a slider 5-2 matching the slide rail 5-1 is provided at the bottom of the top support 2-1. The top support 2-1 is slidably connected to the crossbeam 1-2 through the cooperation of the slider 5-2 and the slide rail 5-1. As shown in Figure 12, a rack 5-3 parallel to the slide rail 5-1 is provided on the crossbeam 1-2, and a second servo motor 5-4 is provided at the bottom of the top support 2-1. A gear 5-5 meshing with the rack 5-3 is connected to the output shaft of the second servo motor 5-4. The second servo motor 5-4 is electrically connected to the control module. During operation, the control module controls the second servo motor 5-4 to drive the gear 5-5 to rotate. Since the gear 5-5 meshes with the rack 5-3, the top support 2-1 is driven to slide along the slide rail 5-1 through the slider 5-2, thereby realizing the lateral movement of the gripping plate mechanism 2 on the support frame 1 to realize the laying of the double-track railway track slab.

[0056] Further, as shown in Figure 4, the claw 2-4 is an L-shaped plate including a vertical part 2-4-1 and a horizontal part 2-4-2. There are four claws 2-4 in total, arranged in pairs on the front and rear sides of the top support 2-1. The two claws 2-4 in a pair face each other, and when the vertical parts 2-4-1 of the two claws 2-4 in a pair are parallel to each other, the distance between their vertical parts 2-4-1 is greater than or equal to the width of the track plate, and the distance between their horizontal parts 2-4-2 is less than the width of the track plate. The opening and closing drive mechanism 2-3 includes four mounting seats 2-3-1, which are respectively hinged to the top of the vertical part 2-4-1 of the four jaws 2-4. Each mounting seat 2-3-1 is provided with a second telescopic cylinder 2-3-2, the two ends of which are respectively hinged to the mounting seat 2-3-1 and the jaws 2-4. When the second telescopic cylinder 2-3-2 extends or retracts, it drives the jaws 2-4 to rotate around its hinge axis with respect to the mounting seat 2-3-1. A second solenoid valve is installed on the oil supply line of the second telescopic cylinder 2-3-2. The second solenoid valve is electrically connected to the control module. During operation, the control module controls the opening and closing of the second solenoid valve, thereby controlling the extension and retraction of the second telescopic cylinder 2-3-2. This causes two clamps 2-4, which are a pair, to rotate in opposite directions around their hinge axis with the mounting base 2-3-1. When they rotate in opposite directions, their vertical parts 2-4-1 clamp onto both sides of the track plate, and their horizontal parts 2-4-2 insert into the bottom of the track plate. Two sets of claws 2-4 are located on the front and rear sides of the top bracket 2-1, respectively, so as to clamp and grasp the track plate. Conversely, when the two claws 2-4, which are in a pair, rotate in opposite directions, the track plate can be released. A connecting rod 2-5 is connected between the two mounting seats 2-3-1 of the two claws 2-4, and the mounting seats 2-3-1 of the two claws 2-4 are connected as one unit. The distance between the two claws 2-4 clamping the track plate on both sides is always fixed, so that the claws 2-4 clamp the track plate more firmly.

[0057] Furthermore, the lifting drive mechanism 2-2 includes four sliding seats 2-2-1 respectively connected to the front and rear sides of the top bracket 2-1. Each sliding seat 2-2-1 has a vertically penetrating first groove. A column 2-2-3 is slidably connected within the first groove of each sliding seat 2-2-1. The lower ends of the four columns 2-2-3 are respectively connected to four mounting seats 2-3-1. A third telescopic cylinder 2-2-4 is provided between each sliding seat 2-2-1 and the mounting seat 2-3-1. The third telescopic cylinder 2-2-4... The ends are respectively hinged to the sliding seat 2-2-1 and the mounting seat 2-3-1. A third solenoid valve is provided on the oil supply line of the third telescopic cylinder 2-2-4. The third solenoid valve is electrically connected to the control module. During operation, the control module controls the opening and closing of the third solenoid valve, thereby controlling the extension and retraction of the third telescopic cylinder 2-2-4. This pushes the mounting seat 2-3-1 to drive the column 2-2-3 to slide up and down along the slide groove of the sliding seat 2-2-1, thereby realizing the opening and closing drive mechanism 2-3 and the claw 2-4 to drive the track plate to move up and down.

[0058] Furthermore, the number of the turning mechanisms 7 is the same as the number of the fine-tuning claws 6, enabling multiple turning mechanisms 7 to simultaneously adjust the fine-tuning claws 6 at different positions. Specifically, as shown in Figures 13 and 14, the turning mechanism 7 includes a motor mounting base 7-1, a third servo motor 7-2, and a fourth servo motor 7-3. The motor mounting base 7-1 is connected to the lower end of the column 2-2-3. The third servo motor 7-2 and the fourth servo motor 7-3 are connected to the motor mounting base 7-1. A first sleeve 7-4 is driven to the output shaft of the third servo motor 7-2, and a second sleeve 7-5 is driven to the output shaft of the fourth servo motor 7-3. The first sleeve 7-4 and the second sleeve 7-5 are vertically downward. The third servo motor 7-2 and the fourth servo motor 7-3 are electrically connected to the control module. During operation, the walking mechanism is controlled by the control module. 3. Drive the support frame 1 to move along the railway track direction, and control the translation drive mechanism 5 to drive the top bracket 2-1 to move laterally perpendicular to the railway track, so that the first sleeve 7-4 and the second sleeve 7-5 are respectively aligned above the vertical adjusting screw 6-2 and the horizontal adjusting screw 6-3 of the fine adjusting claw 6. The control module controls the lifting drive mechanism 2-2 to drive the motor mounting base 7-1 to move downwards until the first sleeve 7-4 and the second sleeve 7-5 are respectively connected to the vertical adjusting screw 6-2 and the horizontal adjusting screw 6-3. According to the position adjustment needs of the track plate, the control module controls the third servo motor 7-2 or the fourth servo motor 7-3 to drive the first sleeve 7-4 or the second sleeve 7-5 to rotate, thereby driving the vertical adjusting screw 6-2 or the horizontal adjusting screw 6-3 to rotate, thereby adjusting the track plate to move in the horizontal direction and the elevation direction perpendicular to the extension direction of the railway track.

[0059] Furthermore, the lower end of the column 2-2-3 is also provided with a horizontal adjustment component 8 and a vertical adjustment component 9. Thus, after the track slab is laid, it is not necessary for the traveling mechanism 3 to drive the entire paving trolley to move so that the first sleeve 7-4 and the second sleeve 7-5 are respectively aligned with the vertical adjustment screw 6-2 and the horizontal adjustment screw 6-3 of the fine adjustment claw 6, and to avoid the claw 2-4 or the opening and closing drive mechanism 2-3 colliding with the track slab when the lifting drive mechanism 2-2 drives the motor mounting seat 7-1 to move downward. It is only necessary to adjust the movement of the first sleeve 7-4 and the second sleeve 7-5 by means of the horizontal adjustment component 8 and the vertical adjustment component 9.

[0060] Specifically, as shown in Figures 14 and 15, the horizontal adjustment assembly 8 includes a horizontal fixed base 8-1, a horizontal slide rail 8-2, a horizontal slider 8-3, and a fourth telescopic cylinder 8-4. The vertical adjustment assembly 9 includes a vertical fixed base 9-1, a vertical slide rail 9-2, a vertical slider 9-3, and a fifth telescopic cylinder 9-4. The horizontal fixed base 8-1 is connected to the lower end of the column 2-2-3. The horizontal slide rail 8-2 is parallel to the extension direction of the railway track and connected to the surface of the horizontal fixed base 8-1. The horizontal slider 8-3 is connected to... On the vertical fixed base 9-1, and the horizontal slider 8-3 is slidably connected to the horizontal slide rail 8-2, the two ends of the fourth telescopic cylinder 8-4 are respectively connected to the horizontal fixed base 8-1 and the vertical fixed base 9-1. When the fourth telescopic cylinder 8-4 extends or retracts, the vertical fixed base 9-1 moves horizontally along the horizontal slide rail 8-2 via the horizontal slider 8-3. The vertical slide rail 9-2 is vertically connected to the vertical fixed base 9-1, and the vertical slider 9-3 is connected to the motor mounting base 7-1. 3. The fifth telescopic cylinder 9-4 is slidably connected to the vertical slide rail 9-2. Its two ends are respectively connected to the vertical fixed base 9-1 and the motor mounting base 7-1. When the fifth telescopic cylinder 9-4 extends or retracts, the motor mounting base 7-1 moves up and down along the vertical slide rail 9-2 via the vertical slider 9-3. The oil supply lines of the fourth telescopic cylinder 8-4 and the fifth telescopic cylinder 9-4 are respectively equipped with a fourth solenoid valve and a fifth solenoid valve. The fourth and fifth solenoid valves are electrically connected to the control module. During operation, the control module... The module controls the opening and closing of the fourth solenoid valve, thereby controlling the extension and retraction of the fourth telescopic cylinder 8-4. This causes the vertical fixed seat 9-1 to move horizontally along the horizontal slide rail 8-2 via the horizontal slider 8-3, thus enabling the adjustment motor mounting seat 7-1 to move along the extension direction of the railway track to align the turning mechanism 7 with the fine-tuning claw 6. The module also controls the opening and closing of the fifth solenoid valve, thereby controlling the extension and retraction of the fifth telescopic cylinder 9-4. This causes the motor mounting seat 7-1 to move up and down, thus enabling the turning mechanism 7 to move up and down and connect with the fine-tuning claw 6.

[0061] Furthermore, as shown in Figures 16 and 17, the top of the adjuster base 6-1 is provided with a second slide groove parallel to the extension direction of the railway track. A longitudinal lead screw 6-6 parallel to the second slide groove is provided in the second slide groove. The two ends of the longitudinal lead screw 6-6 are rotatably connected to the adjuster base 6-1. The bottom of the sliding nut 6-4-5 is slidably connected to the second slide groove at the top of the adjuster base 6-1, and the sliding nut 6-4-5 is threadedly connected to the longitudinal lead screw 6-6. During operation, turning the longitudinal lead screw 6-6 causes the sliding nut 6-4-5 to slide along the second slide groove at the top of the adjuster base 6-1, so that the steering assembly 6-4-1 drives the fixed connecting plate 6-5 to move back and forth relative to the adjuster base 6-1, thereby realizing the fine adjustment of the track plate position parallel to the extension direction of the railway track.
