Description

Technical Field

[0001] The present invention relates to the technical field of track slab production, and in particular to a track slab prefabrication forming production line and a production process. Background Art

[0002] Track slabs are components used to support the tracks in subway construction. They are typically constructed of reinforced concrete, which provides excellent compressive strength. Prefabrication technology involves factory prefabrication and on-site assembly. Centralized production of track slabs in workshops allows for batch dust removal and steam curing, eliminating the need for dispersed on-site pouring operations, thereby achieving energy conservation and environmental protection.

[0003] The track slab is fitted with several track pads, each with a concave cross-section. A track slot for mounting the track is located in the middle of each track pad, and a mounting sleeve is located underneath the slot. During on-site construction, the track mounting bolts are tightened into the mounting sleeve to connect the track slab to the track. The mounting sleeve is pre-buried within the track slab.

[0004] The production mold for a track slab consists of a base mold and side molds. Several side molds are placed on the base mold and surround the casting cavity. The top surface of the base mold is formed with a groove that matches the shape of the track pad. This groove communicates with the casting cavity, and a positioning post is installed within the groove. The operator inserts an installation sleeve onto the positioning post and then pours concrete into the casting cavity. Traditionally, after the concrete has hardened, the side molds are opened. Lifting rings are then screwed into lifting sleeves embedded in the track slab's surface. A sling and hook from a roof crane are then used to lift the rings and separate the track slab from the base mold. This lifting process can cause the track slab to wobble. The top of the positioning post, placed in the installation sleeve, holds the track slab in place, preventing it from shaking. However, just as the top of the positioning post is removed from the installation sleeve and positioned within the track slot, the retaining force of the positioning post on the track slab suddenly disappears, causing the track slab to wobble laterally, causing the positioning post to collide with the sidewalls of the track slot, damaging the track pad and further compromising product quality.

The limiting rod applies a lateral limiting force to the track plate to prevent the track plate from shaking when it is hoisted and further prevents the top of the positioning column from hitting the track pad, thereby preventing the track plate from being damaged by impact and improving product quality.

[0018] (2) The extension and retraction of the limit rod are controlled by the movable side mold, without the need for additional electronic control components. It has reliable functions, quick response and strong load-bearing capacity.

[0019] (3) The height-adjustable sealing end can block the inclined hole, thereby preventing the concrete mortar from flowing into the inclined hole and causing the limit rod to be blocked from extending.

[0020] (4) The sealing end moves longitudinally, avoiding the problem of sharp corner cutting of the lower convex part and pushing dust into the inclined hole caused by the horizontal removal of the sealing strip in the traditional technology, and avoiding the defect of cutting debris and dust blocking the limit rod, thereby ensuring that the limit rod can be smoothly extended from the inclined hole without the need for frequent maintenance and cleaning.

[0021] (5) The electric sealing structure can be completely arranged in the inner cavity of the side mold, minimizing the contact between dust and the electric sealing structure, thereby avoiding dust from blocking the movable parts, improving the functional reliability of the present invention, and eliminating the need for frequent maintenance and cleaning.

[0022] (6) The electric sealing structure adopts electromagnetic drive, which has a lower overall height than the traditional rod drive (such as electric push rod, pneumatic push rod, hydraulic push rod, etc.), so it can be easily installed in the low inner cavity of the side mold.

[0054] Based on the above structural features of the present application, the implementation methods of the present application are further described:

[0055] Reference Figure 1 and Figure 2 The track slab 4 is equipped with several track pads 41 on its upper surface and several protruding steel bars on its lower surface (for cast connection with the foundation). The track pads 41 have a concave cross-section; a track slot 411 for mounting the track is located in the middle of the track pads 41, and a mounting sleeve 412 is located on the bottom surface of the track slot 411. The track pads 41 are reinforced concrete structures. Because the protruding steel bars are difficult to fit into the mold, the track slab 4 is cast in an inverted manner, with the protruding steel bars located at the upper opening of the casting cavity and pointing upward. The bottom surface of the casting cavity is used to form the track pads 41.

[0056] Reference Figures 1 to 4 The bottom surface of the casting cavity is the top surface of the bottom mold assembly 1. The top surface of the bottom mold assembly 1 is provided with a plurality of molding grooves 111. The number, position, shape and size of the molding grooves 111 are respectively adapted to the number, position, shape and size of the track pads 41; a positioning column 112 is provided in the middle of the molding groove 111. The number, position, shape and size of the positioning column 112 are respectively adapted to the number, position, shape and size of the installation sleeve 412, thereby realizing the positioning of the installation sleeve 412.

[0057] Reference Figure 5 , the vehicle lifts the track plate 4 upward; when the top of the positioning column 112 is located in the track slot 411, if the track plate 4 shakes, the top of the positioning column 112 will hit the inner wall of the track slot 411, causing scratches on the inner wall of the track slot 411, and in severe cases, causing an impact notch in the track pad 41.

[0058] Reference Figure 5 , Figure 7 and Figure 24 The present invention aims to limit the track plate 4 at least when the track plate 4 is lifted to a height not greater than h1+h2, thereby preventing it from shaking laterally and further preventing the top of the positioning column 112 from hitting the inner wall of the track slot 411, thereby reducing impact damage and improving product quality.

[0059] Reference Figure 3 and Figure 6 The present embodiment provides a track plate prefabrication molding production line, including a production mold, the production mold including a bottom mold assembly 1, a fixed side mold 2 fixedly connected to the bottom mold assembly 1, and a movable side mold 3 movably connected to the bottom mold assembly 1; the movable side mold 3 can move laterally to approach or move away from the bottom mold assembly 1.

[0060] Reference Figure 3 and Figure 6 The bottom formwork assembly 1 includes a bottom formwork 11 and a limiting structure 12. The bottom formwork 11 is a rectangular plate-like structure, and the bottom formwork 11 is provided with four edges; the fixed side formwork 2 is provided and is arranged at one of the edge positions of the bottom formwork 11, and the movable side formwork 3 is provided and is respectively arranged at the other three edge positions of the bottom formwork 11; the fixed side formwork 2 and the movable side formwork 3 can form a bottom surface and a casting cavity closed on all sides. The fixed side formwork 2 is a box structure composed of a number of steel plates fixedly connected and assembled, and the adjacent steel plates are fixedly connected by welding or by bolts; the bottom formwork 11 and the fixed side formwork 2 are fixedly connected by bolts or by welding. The movable side formwork 3 can move in the vertical direction of the corresponding edge, thereby approaching or moving away from the bottom formwork 11 to achieve mold closing or mold opening.

[0061] Reference Figure 6 , an oblique hole 1102 is provided at the edge of the bottom template 11; the oblique hole 1102 is a straight-through hole. The limiting structure 12 includes a limiting rod 122 inserted into the oblique hole 1102 for limiting the track plate 4. The limiting rod 122 is connected to the movable side mold 3 by a cable 124. When the movable side mold 3 moves in a direction away from the bottom mold, it can pull the limiting rod 122 out of the oblique hole 1102 until the limiting rod 122 abuts against the side wall of the track plate 4. When the track plate 4 is lifted by the vehicle, the limiting rod 122 and the fixed side mold 2 can apply a limiting force to the track plate 4, thereby preventing the track plate 4 from shaking laterally and further preventing the track pad 41 from being damaged by impact.

[0062] Reference Figure 14The movable side form 3 is provided with a height-adjustable sealing end 351 for sealing the inclined hole 1102. After the molds are closed, the height of the sealing end 351 is adjusted to lower it and seal the inclined hole 1102. This prevents concrete mortar from flowing into the inclined hole 1102 (there is inevitably a gap between the movable side form 3 and the bottom form 11), further preventing the inclined hole 1102 from being clogged by hardened concrete mortar, and thus ensuring that the limiting rod 122 can smoothly extend from the inclined hole 1102.

[0063] Reference Figures 6 to 8 , the top end of the inclined hole 1102 is inclined toward the inside of the bottom template 11; the limiting rod 122 can then extend from the inclined hole 1102 in an inclined state, so that the top end of the limiting rod 122 approaches and abuts the track plate 4. If the limiting rod 122 is set vertically, the inclined hole 1102 needs to be set vertically, and the edge of the inclined hole 1102 needs to be close to the side edge of the track plate 4 (to ensure that the limiting rod 122 can contact the track plate 4). The inner edge of the movable side form 3 is used to form the side edge of the track plate 4. Therefore, in the closed mold state, the edge of the inclined hole 1102 needs to be directly below the inner edge of the movable side form 3. If the inclined hole 1102 cannot be blocked, concrete mortar will flow into the inclined hole 1102.

[0064] Reference Figures 7 to 9 The limiting structure 12 also includes a guide sleeve 121 and a first pulley 123; the top of the guide sleeve 121 is connected to the bottom surface of the bottom template 11 (for example, fixedly connected by bolts), and the bottom of the guide sleeve 121 is fixedly connected to the floor or workbench of the processing workshop (for example, fixedly connected by casting or fixedly connected by bolts). The guide sleeve 121 is arranged at an angle so that the guide sleeve 121 and the inclined hole 1102 are in a coaxial state. The guide sleeve 121 is connected to the inclined hole 1102; the bottom end of the limiting rod 122 is inserted into the guide sleeve 121; the side wall of the guide sleeve 121 is provided with a strip hole 1211, which is arranged along the axial direction of the guide sleeve 121 and is a through hole.

[0065] Reference Figures 7 to 9The limiting rod 122 includes a diagonal support rod 1221, a connecting cross rod 1222 and a second pulley 1223. The diagonal support rod 1221 is a straight rod structure. The diagonal support rod 1221 is plugged into the inclined hole 1102 and the guide sleeve 121 respectively; the connecting cross rod 1222 is placed in the strip hole 1211 and fixedly connected to the bottom end of the diagonal support rod 1221, and the connecting cross rod 1222 can slide back and forth along the length direction of the strip hole 1211, thereby driving the diagonal support rod 1221 to extend out of the inclined hole 1102 or retract into the inclined hole 1102. The second pulley 1223 is set at the top of the diagonal support rod 1221, and the second pulley 1223 can rotate freely; when the track plate 4 is lifted upward, the second pulley 1223 is pressed against the outer wall of the track plate 4 and rotates, thereby applying a limiting force to the track plate 4 and minimizing the wear of the limiting rod 122. A tension spring is provided at the bottom end of the inner cavity of the guide sleeve 121, the top end of the tension spring is connected to the bottom end of the diagonal support rod 1221 (for example, fixedly connected or hung by bolts), and the bottom end of the tension spring is hung with a pull ring on the bottom plate 312 of the guide sleeve 121. The bottom plate 312 of the guide sleeve 121 is detachably connected to the side wall by bolts, thereby being used for assembling the tension spring.

[0066] The top of the diagonal support rod 1221 is provided with a receiving groove with a rectangular cross section, and the second pulley 1223 is placed in the receiving groove; the second pulley 1223 is connected to the diagonal support rod 1221 through a rotating shaft. When a bearing is provided between the second pulley 1223 and the rotating shaft, friction is further reduced.

[0067] Reference Figures 7 to 9 The first pulley 123 is mounted on the top of the outer wall of the guide sleeve 121. The first pulley 123 is connected to the guide sleeve 121 via bolts and a rotating shaft, allowing the first pulley 123 to rotate freely. A cable 124 is connected to the connecting crossbar 1222 at one end and to the movable side mold 3 at the other end. The middle portion of the cable 124 is pressed against the first pulley 123.

[0068] Reference Figure 6 and Figure 7 The cable 124 is bent into an L shape. A ring groove is provided on the circumferential surface of the first pulley 123 to fit the cable 124. The bent portion of the cable 124 is pressed into the ring groove. Both the first pulley 123 and the second pulley 1223 are fixed pulleys.

[0069] Reference Figure 6 and Figure 7 From the perspective shown, when the movable side mold 3 moves horizontally to the right, the limit rod 122 can be pulled upward by pulling the cross bar 1222, so that the top of the diagonal support rod 1221 and the second pulley 1223 extend from the inclined hole 1102 until the second pulley 1223 abuts against the track plate 4; when the movable side mold 3 moves horizontally to the left, the tension spring pulls the limit rod 122 downward until the top of the diagonal support rod 1221 and the second pulley 1223 retract into the inclined hole 1102.

[0070] Reference Figure 10 and Figure 11 The movable side mold 3 is provided with a clearance groove 3101 that adapts to the top edge of the bottom mold plate 11. The part of the movable side mold 3 above the clearance groove 3101 is protruding toward the bottom mold plate 11, so that the movable side mold 3 in the mold closing state can block the top opening of the inclined hole 1102 from above, providing accommodation and movable space for the sealing end head 351.

[0071] Reference Figure 11 and Figure 12 The movable side mold 3 includes a side mold 31, a slider 32, a slide rail 33 and a pull-connecting block 34. The slider 32 and the slide rail 33 are respectively fixedly mounted on the bottom surface of the side mold 31 (for example, fixedly connected by bolts). The slide rail 33 is fixedly connected to the bottom mold 11; a strip groove is provided at the side edge of the bottom surface of the bottom mold 11, one end of the slide rail 33 is inserted into the strip groove, and the other end is suspended; the slide rail 33 is fixedly connected to the strip groove by bolts. A reinforcing beam is provided on the lower surface of the slide rail 33, and the top surface of the reinforcing beam is respectively fixedly connected to the bottom surface of the bottom mold 11 and the bottom surface of the slide rail 33 (for example, fixedly connected by bolts or fixedly connected by welding). The length direction of the reinforcing beam is arranged along the length direction of the slide rail 33, thereby providing support for the slide rail 33 and preventing the slide rail 33 from bending due to the weight of the side mold 31. The slider 32 is directly or indirectly connected to the slide rail 33. The slider 32 snaps onto the surface of the slide rail 33; the slider 32 has a C-shaped cross-section, while the slide rail 33 has a gourd-shaped cross-section. The slider 32 snaps onto the upper portion of the slide rail 33 to prevent it from falling off. Lubricant is provided between the slider 32 and the slide rail 33, allowing the slider 32 to slide smoothly on the slide rail 33, thus achieving a direct connection. The bottom surface of the slider 32 is equipped with a number of freely rotating rollers, which are evenly spaced along the length of the slider 32. The rollers have annular grooves on their circumferences. The top surface of the slide rail 33 has a rib that snaps into the bottom of the annular groove. As the rollers roll, the slider 32 slides smoothly on the slide rail 33, achieving an indirect connection.

[0072] Reference Figure 11 and Figure 12The bottom surface of a single side mold 31 is provided with a number of sliders 32 and a number of slide rails 33, thereby achieving stable support for the side mold 31. The number of sliders 32 and slide rails 33 is not less than two, thereby maintaining the balance of the side mold 31 and avoiding unbalanced loading. A number of limiting structures 12 are provided at the same edge position of the bottom mold 11, and the bottom surface of a single side mold 31 is provided with a number of pull-connecting blocks 34 equal to the number of the corresponding limiting structures 12. The pull-connecting blocks 34 correspond to and are connected to the cables 124 one by one (for example, fixedly connected by bolts); the cables 124 are arranged in parallel with each other, thereby ensuring that the limiting rods 122 can extend from the inclined holes 1102 at the same time, at the same speed, and in a mutually adapted state, so as to achieve uniform support for the track plate 4. The number of limiting structures 12 is not less than two, thereby ensuring the balance of the abutment and avoiding unbalanced loading.

[0073] Reference Figure 11 and Figure 12 The slider 32 is pressed against the slide rail 33 and can slide along the length of the slide rail 33. The slider 32 is connected to the bottom mold plate 11 via a hydraulic cylinder 321. The pull block 34 is connected to the cable 124. One end of the slider 32 is pressed against the slide rail 33, and the other end is fixedly connected to the output shaft of the hydraulic cylinder 321 (for example, by bolts). The base of the hydraulic cylinder 321 is fixedly connected to the bottom mold plate 11 via bolts. The hydraulic cylinder 321 is an electrically controlled hydraulic cylinder 321, which is used to drive the side mold 31 to move horizontally, thereby achieving mold opening and closing. There are multiple hydraulic cylinders 321 (no less than two), and the hydraulic cylinders 321 are arranged parallel to each other, so that the side mold 31 can remain parallel to the bottom mold plate 11 during horizontal movement, thereby evenly pulling the limit rod 122.

[0074] Reference Figure 13 The bottom surface of the bottom formwork 11 is fixedly connected to a support leg 1101. The top end of the support leg 1101 is fixedly connected to the bottom formwork 11 (for example, by bolts or welding), and the bottom end of the support leg 1101 is fixedly connected to the floor or workbench of the processing workshop (for example, by casting or bolting). A diagonal square tube 1103 is provided between the support leg 1101 and the slide rail 33 / reinforced crossbeam. The bottom end of the square tube is fixedly connected to the side wall of the support leg 1101 (for example, by casting or bolting), and the top end is fixedly connected to the bottom surface of the slide rail 33 / reinforced crossbeam (for example, by casting or bolting), thereby forming a triangular structure. This improves the load-bearing capacity of the slide rail 33 / reinforced crossbeam and prevents the slide rail 33 / reinforced crossbeam from being bent by the side mold 31.

[0075] Reference Figure 14A height-adjustable sealing end head 351 is provided in the movable side form 3 for sealing the inclined hole 1102. The bottom surface of the sealing end head 351 can adapt to and seal the top opening of the inclined hole 1102. When there is flowing concrete mortar in the casting cavity, the sealing end head 351 needs to press the bottom edge of the sealing end head 351 against the upper surface of the bottom form 11 and place the middle part inside the top of the inclined hole 1102, thereby sealing the inclined hole 1102 and preventing the concrete mortar from flowing into the inclined hole 1102. (After the concrete mortar flows into the inclined hole 1102 and hardens, it will cause the limit rod 122 to adhere to the inner wall of the inclined hole 1102, making it difficult for the limit rod 122 to extend, and even further causing the cable 124 to break and scratch nearby users.)

[0076] Reference Figure 14 The top surface of the clearance groove 3101 is provided with an adapting through hole 3102 that adapts to the inclined hole 1102. When the outer edge of the bottom template 11 is engaged in the clearance groove 3101, the adapting through hole 3102 is located directly above the inclined hole 1102, and the adapting through hole 3102 and the inclined hole 1102 are connected to each other. The sealing end head 351 is located above the adapting through hole 3102 or inserted into the adapting through hole 3102; after the mold is closed, when there is flowing concrete mortar in the casting cavity, the middle and lower part of the sealing end head 351 needs to be inserted into the adapting through hole 3102, and the middle part of the bottom surface of the sealing end head 351 is placed inside the top end of the inclined hole 1102, and the edge of the bottom surface is pressed onto the top surface of the bottom template 11 around the inclined hole 1102 to achieve sealing of the inclined hole 1102; when the mold is opened, the sealing end head 351 needs to be located above the adapting through hole 3102, so as to ensure that the sealing end head 351 will not be cut and damaged when the mold is opened horizontally.

[0077] Reference Figure 15 In conventional technology, the top surface of the clearance groove 3101 is usually tilted, and the edge position of the top surface of the bottom template 11 is also tilted. A sealing strip 3511 is fixedly installed on the top surface of the clearance groove 3101 (for example, by gluing or bolting). When the edge of the top surface of the bottom template 11 is engaged in the clearance groove 3101, the sealing strip 3511 can press the edge of the top surface of the bottom template 11 to seal the inclined hole 1102. However, the inclined hole 1102 is arranged at an angle, so a sharp corner 11021 is formed on the side of the inclined hole 1102 near the outer wall of the bottom mold plate 11. Furthermore, when the sealing strip 3511 is compressed, a lower protrusion 3512 is formed at the top of the inner cavity of the inclined hole 1102 (the sealing strip 3511 is generally made of rubber material, which has excellent elasticity). Therefore, when the side mold 31 and the sealing strip 3511 are laterally separated to open the mold, the sharp corner 11021 will laterally cut the lower protrusion 3512, causing damage to the sealing strip 3511. Cutting the sealing strip 3511 produces cutting debris, which falls into the inclined hole 1102 and is lodged between the limit rod 122 and the inner wall of the inclined hole 1102, preventing the limit rod 122 from extending.

[0078] Reference Figure 15 、 Figure 16 and Figure 17 , traditional technology has proposed a solution to solve the problem of the sharp corner 11021 structure cutting the lower protrusion 3512, namely: setting a rounded corner 11022 at the top of the sharp corner 11021 structure, and the rounded corner 11022 can effectively reduce the cutting damage to the sealing strip 3511. However, dust is inevitably generated during the production of concrete components. The existence of the rounded corner 11022 will cause the outer wall of the limit rod 122 in the extended state and the top of the inner wall of the inclined hole 1102 to form a first gap 11023 with a funnel-shaped cross section, which will cause more dust to fall into the inclined hole 1102. Users need to frequently inspect and remove the dust particles accumulated in the inclined hole 1102 to avoid the limit rod 122 from getting stuck. Figure 16 From the perspective shown, when the sealing strip 3511 moves horizontally to the left, the dust on the upper surface of the bottom template 11 and on the right side of the inclined hole 1102 will be pushed into the inclined hole 1102, which further increases the dust entry speed of the inclined hole 1102. Therefore, the maintenance frequency needs to be further increased, which is time-consuming and labor-intensive and reduces production efficiency.

[0079] Reference Figure 18 The sealing end head 351 of the present invention blocks the inclined hole 1102 in the form of longitudinal movement, thereby avoiding the problem that the dust on the surface of the bottom template 11 is pushed into the inclined hole 1102 due to lateral movement.

[0080] Reference Figure 18 When the sealing end head 351 of the present invention is pressed against the inclined hole 1102 on the upper surface of the bottom template 11, a lower convex portion 3512 will be formed on the bottom surface of the sealing end head 351 due to the effect of pressure. However, since the sealing end head 351 moves longitudinally, neither the pointed corner 11021 structure nor the rounded corner 11022 structure will cut the lower convex portion 3512 at the bottom end of the sealing end head 351, thereby improving the service life of the sealing end head 351 and preventing cutting debris from falling into the inclined hole 1102 (under the action of pressure, the pointed corner 11021 may press the root of the lower convex portion 3512 to cause cracking at this position, but the crack is longitudinal, and there is no transverse relative movement between the sealing end head 351 and the pointed corner 11021, so no transverse crack will extend on the basis of the longitudinal crack, so no cutting debris will be generated, and the lower convex portion 3512 will not fall off).

[0081] The movable side mold 3 also includes a sealing structure 35. The sealing structure 35 is divided into a manual type and an electric type.

[0082] Reference Figure 19The manual sealing structure 35 includes a sealing end 351, a first column 352, a second column 353, and a stopper 354. The bottom end of the first column 352 is connected to the sealing end 351 (for example, by bolts, annular clamping, or bonding). The stopper 354 is fixedly mounted on the side wall of the inner cavity of the side mold 31 (for example, by bolts or welding). The stopper 354 is provided with a first insertion hole, into which the first column 352 is inserted and can slide longitudinally. The top of the first column 352 is provided with a first screw hole, into which the lower portion of the second column 353 is inserted and threaded. The lower portion of the outer wall of the second column 353 is provided with an external thread adapted to the first screw hole, which engages with the first screw hole. The upper portion of the second column 353 is inserted into the top hole on the top surface of the side mold 31 and is connected by annular clamping. Two retaining rings 3531 are provided on the upper outer wall of the second column 353. These retaining rings 3531 are fixedly connected to the second column 353 via radial bolts. These retaining rings 3531 respectively engage the top and bottom surfaces of the top plate 311 of the side mold 31, maintaining the height of the second column 353 and driving the longitudinal movement of the first column 352. Rotation of the second column 353, through the external threads and the first screw hole, enables longitudinal movement of the first column 352, thereby driving longitudinal movement of the sealing end 351. A knob 3532 is provided at the top of the second column 353 (e.g., fixedly connected via bolts). The knob 3532 is located above the side mold 31 for easy gripping. The first column 352 has a non-circular cross-section, preventing it from rotating within the first insertion hole and enabling height adjustment. The first insertion hole fits and engages the outer wall of the first column 352, allowing the first column 352 to slide longitudinally within the first insertion hole. The cross-sectional outer contour of the first column 352 is rectangular or square; the cross-section of the first plug hole is rectangular or square to fit the first column 352, thereby preventing the first column 352 and the sealing end 351 from rotating (when the sealing end 351 moves downward in a rotating manner, the top edge of the inclined hole 1102 will cause the root of the lower protrusion 3512 to be cut, resulting in cutting debris). The user grasps the knob 3532 and rotates it, causing the second column 353 to rotate, thereby driving the first column 352 and the sealing end 351 to move longitudinally. The cross-section of the second column 353 is circular, ensuring smooth engagement of the external thread with the first screw hole. The manual sealing structure 35 has a low manufacturing cost.

[0083] Reference Figure 20The electric sealing structure 35 can be completely installed in the inner cavity of the side mold 31, thereby preventing dust from blocking the movable parts within the sealing structure 35. The electric sealing structure 35 includes a sealing end 351, a third column 355, a first support plate 356, a second support plate 357, and an adsorption ring 358. The bottom end of the third column 355 is connected to the sealing end 351 (for example, by bolts, annular clamping, or adhesive connection); the first support plate 356 and the second support plate 357 are respectively fixedly connected to the side wall of the inner cavity of the side mold 31 (for example, by bolts or welding); the first support plate 356 has a first receiving hole that adapts to the cross-section of the third column 355, and the second support plate 357 has a second receiving hole that adapts to the cross-section of the third column 355. The third column 355 is inserted into the first and second receiving holes and can slide longitudinally; the first receiving hole is located directly above the second receiving hole. A gap of at least 3 cm is provided between the first support plate 356 and the second support plate 357. The first and second receiving holes respectively fit over the upper and lower portions of the third column 355, ensuring that the third column 355 can only move longitudinally. A stop plate 3551 is provided at the top of the third column 355 (e.g., secured by bolts). A compression spring 3552 is positioned between the stop plate 3551 and the first support plate 356, and is positioned around the outer wall of the third column 355. The first support plate 356 is positioned above the second support plate 357. The compression spring 3552 is used to push the third column 355 upward and reset. An attraction ring 358 is secured to the outer wall of the third column (e.g., secured by bolts). An electromagnetic ring 3571 is positioned on the top surface of the second support plate 357, positioned between the electromagnetic ring 3571 and the first support plate 356. The electromagnetic ring 3571 fits around the outer periphery of the third column. The suction ring 358 is positioned above the electromagnetic coil 3571. A gap is provided between the suction ring 358 and the electromagnetic coil 3571 to provide space for the suction ring 358 to move downward. A gap is provided between the suction ring 358 and the first support plate 356 to provide space for the suction ring 358 to move upward. The electromagnetic coil 3571 is fixedly connected to the second support plate 357 via bolts. When the electromagnetic coil 3571 is activated, it generates a magnetic force that attracts the suction ring 358 and drives the suction ring 358, the third column 355, and the sealing end 351 to move downward synchronously, ultimately causing the sealing end 351 to press against the inclined hole 1102 on the top surface of the bottom template 11, thereby sealing the inclined hole 1102.

[0084] The outer contour of the cross section of the third column 355 is a rectangle or a square; the cross section of the first accommodating hole and the cross section of the second accommodating hole are both rectangles or squares adapted to the third column 355, thereby preventing the third column 355 and the sealing end 351 from rotating (when the sealing end 351 moves downward in a rotating form, the top edge of the inclined hole 1102 will cause the root of the lower protrusion 3512 to be cut, resulting in cutting debris).

[0085] The electric sealing structure 35 utilizes electromagnetic drive, resulting in a lower overall height compared to traditional rod-type actuators (such as electric, pneumatic, or hydraulic actuators), allowing for convenient installation within the low interior cavity of the side mold 31. The track plate 4 is typically 340 mm thick, resulting in a 340 mm height difference between the top surface of the side mold 31 and the top surface of the bottom mold plate 11. The available height within the side mold 31 cavity is calculated as 340 mm minus 8 mm (the thickness of the top plate 311), which equals 332 mm. A height of 332 mm makes it difficult to accommodate a conventional vertical rod-type actuator. A miniature rod-type actuator would struggle to provide sufficient pressure on the sealing end 351 and maintain a fast response speed. The flat design of the electromagnetic coil 3571 allows for installation within a compact space. The electromagnetic force can be increased by increasing the number of coil turns, increasing the current, and / or increasing the mass of the coil core. Furthermore, the electromagnetic coil 3571 exhibits a high degree of responsiveness, does not occupy a large vertical space, and improves operational efficiency.

[0086] Reference Figure 21 The side mold 31 includes a top plate 311, a bottom plate 312, a side plate 313, and an inner support plate 314. The top plate 311 and the bottom plate 312 are both arranged horizontally and parallel to each other, with the top plate 311 located directly above the bottom plate 312. The side plate 313 is arranged vertically and is placed at a side edge of the top plate 311 close to the casting cavity. The top end of the side plate 313 is sealed and fixedly connected to the edge of the top plate 311 (for example, by welding), and the bottom end is sealed and fixedly connected to the edge of the bottom plate 312 (for example, by welding). The inner support plate 314 is arranged vertically between the top plate 311 and the bottom plate 312. The side edge of the inner support plate 314 is vertically fixedly connected to the side plate 313 (for example, by welding), the top edge of the inner support plate 314 is vertically fixedly connected to the top plate 311 (for example, by welding), and the bottom edge is vertically fixedly connected to the bottom plate 312 (for example, by welding). The top plate 311 , the bottom plate 312 , the side plates 313 and the inner support plates 314 are surrounded to form a plurality of accommodating cavities, and the entire or part of the sealing structure 35 is located in the accommodating cavities, thereby minimizing the damage of dust to the sealing structure 35 and preventing the sealing structure 35 from getting stuck.

[0087] Reference Figure 19 The external thread at the bottom end of the second column 353 and the first screw hole at the top end of the first column 352 are both located in the accommodating cavity, thereby ensuring smooth transmission; the limit block 354 is located in the accommodating cavity, thereby preventing dust from clogging the gap between the first column 352 and the first plug-in hole, ensuring the smoothness of the longitudinal movement of the first column 352.

[0088] Reference Figure 19 and Figure 22The stopper 354 is fixedly disposed at the connection between the side plate 313 and the inner support plate 314. One side of the stopper 354 is fixedly connected to the side plate 313 (e.g., by welding or bolts), and the other side of the stopper 354 is fixedly connected to the inner support plate 314 (e.g., by welding or bolts), thereby achieving installation of the sealing structure 35. A top hole for accommodating the second column 353 is provided on the top plate 311, directly above the stopper 354.

[0089] Reference Figure 20 and Figure 23 The first support plate 356 is fixedly arranged at the connection position between the side plate 313 and the inner support plate 314, one side of the first support plate 356 is fixedly connected to the side plate 313 (for example, welded or fixedly connected by bolts), and the other side of the first support plate 356 is fixedly connected to the inner support plate 314 (for example, welded or fixedly connected by bolts); the second support plate 357 is fixedly arranged at the connection position between the side plate 313 and the inner support plate 314, one side of the second support plate 357 is fixedly connected to the side plate 313 (for example, welded or fixedly connected by bolts), and the other side of the second support plate 357 is fixedly connected to the inner support plate 314 (for example, welded or fixedly connected by bolts); thereby realizing the installation of the sealing structure 35.

[0090] The side mold 31 also includes a back plate, which is arranged on the side of the top plate 311 away from the casting cavity. The back plate is upright, and the top edge of the back plate is in contact with the edge of the top plate 311, and the bottom edge is in contact with the edge of the bottom plate 312; the back plate is in contact with the edge of the inner support plate 314 and is detachably connected by bolts; a nut is welded and fixed to the edge of the inner support plate 314 near the back plate, and a second plug hole is provided on the back plate to adapt to the nut. The user penetrates the bolt through the second plug hole and screws it with the nut. The back plate is used to block the accommodating cavity, so that as little dust as possible enters the accommodating cavity, thereby improving the transmission smoothness and service life of the sealing structure 35. A wiring hole is provided on the back plate for laying the wires connected to the electromagnetic coil 3571.

[0091] Reference Figure 7 and Figure 24 When the second pulley 1223 abuts the track plate 4, the height of the protruding portion of the limiting rod 122 is H. The height of the protruding portion of the positioning post 112 is h1, and the depth of the track retaining groove 411 is h2. H ≥ (h1 + h2), thereby ensuring that the limiting rod 122 can exert a limiting force on the track plate 4 at least before the top of the positioning post 112 is withdrawn from the track retaining groove 411.

[0092] The hydraulic cylinder 321 is connected to and communicates with a liquid pump and an oil tank through an oil pipe. The liquid pump and the oil tank are placed on the ground or a workbench.

[0093] The present invention also includes an electrical cabinet, which is bolted to the bottom surface of the base plate 11. The hydraulic cylinder 321 and the electromagnetic coil 3571 are connected to the electrical cabinet via wires and signal lines. The electrical cabinet is also connected to an external power supply and an external computer via wires and signal lines. The computer controls the start and stop of the hydraulic cylinder 321 and the electromagnetic coil 3571 through the electrical cabinet. The suction ring 358 is made of ferrous metal (e.g., 45-gauge steel).

[0094] Reference Figure 20 The third column 355 is made of non-magnetic material (such as plastic, wood, etc.), thereby preventing the electromagnetic coil 3571 from laterally adsorbing the third column 355 and improving the transmission smoothness of the sealing structure 35.

[0095] The cable 124 is a steel wire rope or a high-strength polyethylene fiber rope, and thus has excellent load-bearing capacity.

[0096] The sealing end head 351 is made of rubber material and thus has excellent elasticity.

[0097] The track slab precast forming line also includes a vibrating rod, a curing table, and a moisturizing film. The curing table is mounted on the bottom surface of the base formwork 11 (e.g., fixedly connected by bolts). A fluid conduit is provided within the curing table, which is connected to a boiler plant via an external pipe. The boiler plant injects high-temperature steam into the conduit, curing the concrete in the curing table and the pouring cavity.

[0098] A track slab prefabrication production process, i.e., using a track slab prefabrication production line to manufacture track slabs 4, comprises the following steps: S1, closing the mold so that a movable side mold 3 and a fixed side mold 2 surround and form a casting cavity closed on all sides; S2, laying a steel mesh and embedded parts in the casting cavity; S3, pouring concrete mortar in the casting cavity and vibrating the concrete mortar evenly using a vibrator; S4, curing and hardening the concrete mortar; S5, opening the mold.

[0099] Step S1 further includes the following steps: S11, driving the side mold 31 to move horizontally and approach the bottom template 11, so that the edge of the bottom template 11 is engaged in the makeshift groove 3101; during the process, the top end of the limiting rod 122 retracts into the inclined hole 1102; S12, driving the sealing end 351 to move downward until the sealing end 351 blocks the top opening of the inclined hole 1102.

[0100] Step S4 further includes the following steps: S41, covering the fixed side form 2 and the movable side form 3 with a moisturizing film so that the moisturizing film can cover the top opening of the pouring cavity and the concrete in the pouring cavity; S42, opening the valve on the outer tube and injecting high-temperature steam into the steaming table.

[0101] Step S5 further includes the following steps: S51, driving the sealing end head 351 to move upward until the bottom end of the sealing end head 351 is located above the top of the adapter through hole 3102; S52, driving the side mold 31 to move horizontally and away from the bottom template 11 to achieve demolding of the side of the track plate 4; during the process, the side mold 31 pulls the limit rod 122 through the cable 124 to extend from the inclined hole 1102 until the second pulley 1223 is pressed against the side wall of the track plate 4; S53, using the crane's sling and hook to hook and lift the track plate 4 to achieve demolding of the bottom surface of the track plate 4.

[0102] In the present invention, when the movable side mold 3 is opened, the limiting rod 122 can be pulled out from the inclined hole 1102 until the limiting rod 122 abuts against the side wall of the track plate 4; the limiting rod 122 applies a lateral limiting force to the track plate 4 to prevent the track plate 4 from shaking when it is hoisted and lifted, and further avoids the problem of the top of the positioning column 112 hitting the track pad 41, so as to avoid the track plate 4 from being damaged by the impact and improve the product quality. The extension and retraction of the limiting rod 122 are controlled by the movable side mold 3, and no additional electronic control components are required. It has reliable functions, quick response, and strong load-bearing capacity. The height-adjustable sealing end 351 can block the inclined hole 1102, thereby avoiding the problem of concrete mortar flowing into the inclined hole 1102 and causing the limiting rod 122 to be blocked from extending.
