Description

Technical Field

[0001] The 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 tracks in subway projects. They are usually made of reinforced concrete, which gives them excellent compressive resistance. Prefabrication technology refers to the production and construction form of factory prefabrication and on-site assembly. Track slabs are centrally produced in workshops, and can be dusted and steamed in batches, avoiding the dispersed operation of on-site pouring, thus achieving energy conservation and environmental protection.

[0003] There are several track pads on the surface of the track plate, and the cross section of the track pad is concave; a track slot for installing the track is provided in the middle of the track pad, and a mounting sleeve is provided on the bottom of the track slot. During on-site construction, the bolts used to install the track are tightened in the mounting sleeve to achieve the connection between the track plate and the track. The mounting sleeve is installed in the track plate in a pre-buried form.

[0004] The production mold of the track plate includes a bottom mold and a side mold. Several side molds are placed on the bottom mold and surround to form a casting cavity. The upper surface of the bottom mold is provided with a molding groove adapted to the shape of the track pad. The molding groove is connected to the casting cavity, and a positioning column is vertically arranged in the molding groove. The user sleeves the installation sleeve on the positioning column and then pours concrete into the casting cavity. In the traditional technology, after the concrete hardens, the side mold is first opened, and then the lifting ring is screwed into the lifting sleeve pre-embedded on the surface of the track plate. Then, the lifting rope and hook of the roof crane are used to hook the lifting ring and lift the track plate to separate the track plate from the bottom mold. The track plate will shake during the lifting of the track plate by the lifting rope. The top of the positioning column is placed in the installation sleeve to limit the track plate and prevent the track plate from shaking. When the top of the positioning column is just pulled out of the installation sleeve and is located in the track slot, the limiting force of the positioning column on the track plate suddenly disappears, and the track plate will shake laterally, causing the positioning column to collide with the side wall of the track slot, resulting in damage to the track pad, further reducing the product quality of the track plate.

[0024] Based on the above structural features of the present application, the implementation methods of the present application are further described: Reference Figure 1 and Figure 2The track plate 4 has a plurality of track pads 41 on its upper surface and a plurality of protruding steel bars (for pouring and connecting with the foundation) on its lower surface. The vertical section of the track pad 41 is in a concave shape; a track slot 411 for installing the track is provided in the middle of the track pad 41, and a mounting sleeve 412 is provided on the bottom surface of the track slot 411. The track pad 41 is a reinforced concrete structure, and since the protruding steel bars are difficult to fit into the mold, the track plate 4 is poured in an inverted manner, so that the protruding steel bars are located at the upper opening of the pouring cavity and point upward, and the bottom surface of the pouring cavity is used to form the track pad 41.

[0025] Reference Figure 1 to Figure 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.

[0026] 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 on the track pad 41.

[0027] Reference Figure 5 , Figure 7 and Fig.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, to prevent it from lateral shaking, and further to prevent 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.

[0028] Reference Figure 3 and Figure 6 The present embodiment provides a rail slab prefabrication molding production line, including a production mold, the production mold includes 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.

[0029] Reference Figure 3 and Figure 6The bottom mold assembly 1 includes a bottom mold 11 and a limiting structure 12.

The limiting structure 12 includes a limiting rod 122 inserted in the inclined hole 1102 for limiting the track plate 4. The limiting rod 122 is connected to the movable side mold 3 through 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 inclined hole 1102 until the limiting rod 122 abuts against the side wall of the track plate 4. When the vehicle lifts the track plate 4, 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.

[0031] Reference Fig.14 The movable side mold 3 is provided with a sealing end 351 with an adjustable height for blocking the inclined hole 1102. After the mold is closed, the height of the sealing end 351 is adjusted to reduce the height of the sealing end 351 and block the inclined hole 1102, so as to prevent the concrete mortar from flowing into the inclined hole 1102 (there is inevitably a gap between the movable side mold 3 and the bottom mold 11), and further prevent the inclined hole 1102 from being blocked by hardened concrete mortar, thereby ensuring that the limit rod 122 can smoothly extend from the inclined hole 1102.

[0032] Reference Figure 6 to Figure 8 , the top of the inclined hole 1102 is inclined toward the inside of the bottom template 11; then the limiting rod 122 can extend from the inclined hole 1102 in an inclined state, so that the top of the limiting rod 122 is close to and abuts the track plate 4. If the limiting rod 122 is set vertically, the inclined hole 1102 needs to be set vertically, and further 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), and the inner edge of the movable side mold 3 is used to form the side edge of the track plate 4, so the edge of the inclined hole 1102 needs to be located directly below the inner edge of the movable side mold 3 in the mold closing state, and the inclined hole 1102 cannot be blocked, and concrete mortar will flow 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 diagonal bracing square tube 1103 is provided between the leg 1101 and the slide rail 33 / reinforced cross beam, the bottom end of the square tube is fixedly connected to the side wall of the leg 1101 (for example, by casting or bolts), and the top end is fixedly connected to the bottom surface of the slide rail 33 / reinforced cross beam (for example, by casting or bolts), thereby forming a triangular structure, thereby improving the bearing capacity of the slide rail 33 / reinforced cross beam and preventing the slide rail 33 / reinforced cross beam from being bent by the side mold 31.

[0044] Reference Fig.14The movable side mold 3 is provided with a sealing end 351 with adjustable height for sealing the inclined hole 1102, and the bottom surface of the sealing end 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 351 needs to press the bottom edge position on the upper surface of the bottom mold plate 11 and place the middle part in the top of the inclined hole 1102, so as to achieve the sealing of the inclined hole 1102 and prevent 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 cause the cable 124 to break and scratch nearby users).

[0045] Reference Fig.14 The top surface of the clearance groove 3101 is provided with an adapting through hole 3102 adapted 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 concrete mortar that can flow 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 crimped onto the top surface of the bottom template 11 around the inclined hole 1102, so as to achieve the blocking of the inclined hole 1102; when opening the mold, 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.

[0046] Reference Fig.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 structure is formed on the side of the inclined hole 1102 close to the outer wall of the bottom mold plate 11; and after the sealing strip 3511 is compressed, a lower convex portion 3512 is formed at the top of the inner cavity of the inclined hole 1102 (the sealing strip 3511 is usually made of rubber material, so it has excellent elasticity). When the side mold 31 and the sealing strip 3511 are laterally pulled apart to open the mold, the sharp corner 11021 structure will laterally cut the lower convex portion 3512, causing damage to the sealing strip 3511. Cutting the sealing strip 3511 produces cutting debris, which will fall into the inclined hole 1102 and be stuck between the limit rod 122 and the inner wall of the inclined hole 1102, causing the limit rod 122 to be unable to extend.

[0047] Reference Fig.15 , Fig.16 and Fig.17 , conventional technology has proposed a solution to solve the problem of the sharp corner 11021 structure cutting the lower protrusion 3512, namely: a rounded corner 11022 is set 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 a first gap 11023 with a funnel-shaped cross-section to be formed between the outer wall of the limit rod 122 in the extended state and the top of the inner wall of the inclined hole 1102, 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. Refer to Fig.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.

[0048] Reference Fig.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.

[0049] Reference Fig.18 When the sealing end head 351 of the present invention is crimped onto the inclined hole 1102 on the upper surface of the bottom template 11, a lower convex portion 3512 is 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 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 effect of pressure, the pointed corner 11021 may crimp the root of the lower convex portion 3512 to cause a crack at this position, but the crack is longitudinal, and there is no lateral relative movement between the sealing end head 351 and the pointed corner 11021, so no lateral crack will extend from the longitudinal crack, so no cutting debris will be generated, and the lower convex portion 3512 will not fall off).

[0050] 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.

[0051] Reference Fig.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, fixedly connected by bolts, fixedly connected by annular clamping or fixedly connected by bonding); the stopper 354 is fixedly installed at the side wall of the inner cavity of the side mold 31 (for example, fixedly connected by bolts or fixedly connected by welding), and the stopper 354 is provided with a first plug hole, and the first column 352 is plugged into the first plug hole and can slide longitudinally; the top of the first column 352 is provided with a first screw hole, and the lower part of the second column 353 is plugged into the first screw hole and connected by threads. The lower part of the outer wall of the second column 353 is provided with an external thread adapted to the first screw hole, and the external thread is engaged with the first screw hole. The upper part of the second column 353 is plugged into the top hole on the top surface of the side mold 31 and is connected by annular clamping. Two snap rings 3531 are provided on the outer side wall of the upper part of the second column 353. The snap rings 3531 are fixedly connected to the second column 353 by radial bolts. The two snap rings 3531 are respectively attached to the top and bottom surfaces of the top plate 311 of the side mold 31, so as to maintain the height of the second column 353 unchanged, and are used to drive the first column 352 to move longitudinally. When the second column 353 rotates, it can drive the first column 352 to move longitudinally through the external thread and the first screw hole, and then drive the sealing end 351 to move longitudinally; a knob 3532 is provided on the top of the second column 353 (for example, fixedly connected by bolts), and the knob 3532 is located above the side mold 31 so as to facilitate the user to grasp it. The cross section of the first column 352 is non-circular, so as to prevent the first column 352 from rotating in the first plug hole, and is used to achieve the height adjustment of the first column 352. The first plug hole is adapted to and attached to the outer side wall of the first column 352, and the first column 352 can slide longitudinally in the first plug hole. The outer contour of the cross section of the first column 352 is a rectangle or a square; the cross section of the first plug hole is a rectangle or a square adapted to 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 form, the top edge of the inclined hole 1102 will cut the root of the lower protrusion 3512, resulting in cutting debris). The user grasps the knob 3532 and rotates it, driving 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, thereby ensuring the smoothness of the engagement between the external thread and the first screw hole. The manual sealing structure 35 has a lower manufacturing cost.

[0052] Reference Fig. 20, the electric sealing structure 35 can be completely arranged in the inner cavity of the side mold 31, so as to prevent dust from blocking the movable parts in 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, by annular clamping or by bonding); 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 by welding); the first support plate 356 is provided with a first receiving hole adapted to the cross section of the third column 355, and the second support plate 357 is provided with a second receiving hole adapted to the cross section of the third column 355. The third column 355 is inserted and arranged in the first receiving hole and the second receiving hole and can slide longitudinally; the first receiving hole is located directly above the second receiving hole. There is a gap of not less than 3 cm between the first support plate 356 and the second support plate 357, and the first receiving hole and the second receiving hole are respectively sleeved on the upper and lower positions of the third column 355, so as to ensure that the third column 355 can only move longitudinally. A limit plate 3551 is provided at the top of the third column 355 (for example, fixedly connected by bolts), and a compression spring 3552 is provided between the limit plate 3551 and the first support plate 356, and the compression spring 3552 is sleeved on the outer wall of the third column 355; the first support plate 356 is located above the second support plate 357. The compression spring 3552 is used to push the third column 355 upward to reset. The adsorption ring 358 is sleeved and fixed on the outer wall of the third column head (for example, fixedly connected by bolts); an electromagnetic ring 3571 is provided on the upper surface of the second support plate 357, and the adsorption ring 358 is placed between the electromagnetic ring 3571 and the first support plate 356, and the electromagnetic ring 3571 is sleeved on the outer periphery of the third column head. The adsorption ring 358 is located above the electromagnetic ring 3571, and a gap is provided between the adsorption ring 358 and the electromagnetic ring 3571, and the gap is used to provide space for the adsorption ring 358 to move downward; a gap is provided between the adsorption ring 358 and the first support plate 356, and the gap is used to provide space for the adsorption ring 358 to move upward. The electromagnetic ring 3571 is fixedly connected to the second support plate 357 by bolts. When the electromagnetic ring 3571 is started, a magnetic force is generated, which can attract the adsorption ring 358 and drive the adsorption ring 358, the third column 355 and the sealing end 351 to move downward synchronously, and finally the sealing end 351 is pressed against the position of the inclined hole 1102 on the top surface of the bottom template 11, so as to achieve the blocking of the inclined hole 1102.

[0053] The outer contour of the cross section of the third column 355 is a rectangle or a square; the cross section of the first receiving hole and the cross section of the second receiving 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).

[0054] The electric sealing structure 35 is electromagnetically driven, and has a lower overall height than the traditional rod-type drive (such as electric push rod, pneumatic push rod, hydraulic push rod, etc.), so it can be easily adapted to be installed in the low inner cavity of the side mold 31. The thickness of the track plate 4 is generally 340 mm, and the height difference between the top surface of the side mold 31 and the top surface of the bottom mold plate 11 is 340 mm, so the available height of the inner cavity of the side mold 31 = 340-8 (the thickness of the top plate 311) = 332 mm. The height of 332 mm is difficult to accommodate a vertical ordinary rod-type drive; if a micro-rod-type drive is used, it is difficult to provide sufficient pressure to the sealing end 351 and it has a faster response speed; and the electromagnetic coil 3571 is flat as a whole, can be adapted to be installed in a flat space, and can increase the electromagnetic force by increasing the number of coil turns, increasing the current intensity and / or increasing the mass of the iron core in the coil, and it is sensitive to its own response, does not occupy a large longitudinal space, and can also improve work efficiency.

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.

[0060] Reference Figure 7 and Fig.24 , when the second pulley 1223 contacts the track plate 4, the height of the protruding portion of the top end of the limiting rod 122 is H. The height of the protruding portion of the top end of the positioning column 112 is h1, and the depth of the track slot 411 is h2. H≥(h1+h2), thereby ensuring that the limiting rod 122 can apply a limiting force to the track plate 4 at least before the top end of the positioning column 112 is withdrawn from the track slot 411.

The adsorption ring 358 is made of ferrous metal material (such as 45 steel).

[0063] Reference Fig. 20 The third column 355 is made of non-magnetic material (such as plastic, wood, etc.), so as to avoid the electromagnetic coil 3571 from lateral adsorption of the third column 355 and improve the transmission smoothness of the sealing structure 35.

[0064] The cable 124 is a steel wire rope or a high-strength polyethylene fiber rope, and thus has excellent load-bearing capacity.

[0065] The sealing end head 351 is made of rubber material and thus has excellent elasticity.

[0066] The track slab prefabrication production line also includes a vibrating rod, a steam curing table and a moisturizing film; the steam curing table is fitted to the bottom surface of the bottom template 11 (for example, fixedly connected by bolts), and a fluid pipeline is provided in the steam curing table, which is connected and communicated with the boiler plant through an external pipe. The boiler plant injects high-temperature steam into the fluid pipeline, thereby performing high-temperature steam curing on the steam curing table and the concrete in the pouring cavity.
