[0050] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. 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.

[0051] Example 1

[0052] Please refer to the accompanying drawings. This invention provides a technical solution:

[0053] A hydraulic tunnel segment casting equipment includes a first base 1 and a forming mold 5. The top surface of the first base 1 is fixed with a first placement seat 3, a second placement seat 301 and a third placement seat 302 in sequence from back to front. Vertical side plates are symmetrically fixed on both sides of the middle of the top surface of the first base 1. A mixing tank 2 is fixed between the two side plates. The bottom of the mixing tank 2 is provided with a discharge pipe 201 and a valve.

[0054] A feeding assembly is provided on one side of the mixing tank 2, and a screening assembly is provided on the top surface of the mixing tank 2. The screening assembly has a material inlet and a material blocking assembly. A drive box 204 is rotatably connected to the center of the screening assembly. The bottom of the drive box 204 is fixed to the upper side wall of the mixing tank 2 by a plurality of evenly arranged support rods 205.

[0055] A vertical stirring shaft 202 is provided at the center of the mixing tank 2. Multiple stirring blades 203 are evenly provided on the stirring shaft 202. The stirring shaft 202 is rotatably connected to the drive box 204, and its top end extends out of the drive box 204 and is connected to a motor. A transmission component is provided in the lower part of the inner cavity of the drive box 204, and the transmission component is correspondingly connected to the stirring shaft 202 and the screening component.

[0056] The top surfaces of the first placement seat 3, the second placement seat 301 and the third placement seat 302 are arc-shaped, and the interior of the second placement seat 301 and the third placement seat 302 is provided with a drive cavity, in which two vibration components are symmetrically arranged.

[0057] The molding mold 5 includes an arc-shaped molding groove 501 and an arc-shaped cover plate 502 that is detachably fixed to the top of the molding groove 501. A pouring port 507 is provided in the middle of the top surface of the cover plate 502. Vertical support plates 508 are symmetrically fixed on both sides of the bottom of the molding groove 501. Vibration components are symmetrically provided between the two side plates, and the vibration components are correspondingly connected to the cover plate 502. The molding groove 501 is located on two vibration components of the second placement seat 301, and the top surface of the first base 1 is provided with moving components corresponding to the bottom sides of the molding groove 501.

[0058] The movable component includes end plates 101 symmetrically fixed at the front and rear ends of the first base 1. Two first screws 102 are arranged parallel to each other and rotatably connected between the two end plates 101. The first placement seat 3, the second placement seat 301 and the third placement seat 302 are located between the two first screws 102. The first screws 102 are rotatably connected to the end plates 101 and have a motor connected to one end. A movable seat 103 is threaded onto the first screws 102. Two hydraulic telescopic rods 104 are symmetrically fixed to the top surface of the movable seat 103. A top plate 105 is fixed to the top of the hydraulic telescopic rods 104 and is correspondingly connected to the bottom of the forming groove 501.

[0059] Before the segment casting, the material is conveyed to the screening component through the feeding component. If the material does not need to be screened, the material port is opened through the material blocking component, and the screening component and the material port are rotated through the mixing shaft 202 and the transmission component. The material port is located at the feeding component, so that the material enters the mixing tank 2 directly without being screened.

[0060] If the material needs to be screened, the feed inlet is closed by the baffle assembly, and the screening assembly is rotated by the stirring shaft 202 and the transmission assembly, so that the material falls evenly onto the screening assembly, avoiding material accumulation and speeding up the screening process.

[0061] The material enters the mixing tank 2, and the motor and mixing shaft 202 drive multiple mixing blades 203 to rotate, thereby mixing the material and improving the mixing effect. Mixing and feeding are carried out simultaneously, which speeds up the processing efficiency. Furthermore, the working status of the screening components can be switched according to the material, which improves the flexibility of the equipment.

[0062] The molding mold 5 is placed on top of the first placement seat 3, and the structure of the molding mold 5 and the steel reinforcement structure are installed and processed. Then, the top plate 105 of the moving component moves to the first placement seat 3, and the molding mold 5 is lifted by the hydraulic telescopic rod 104, separating it from the first placement seat 3. It is then moved to the top of the second placement seat 301 by the first screw 102 and the moving seat 103, and then falls down onto the vibration component. The concrete material is transported back to the pouring port 507 and the molding mold 5 through the discharge pipe 201 of the mixing tank 2. The molding mold 5 is vibrated by the vibrating components on both sides, and the concrete on both sides is vibrated to improve the concrete placement effect.

[0063] After the concrete feeding is completed, the molding mold 5 is moved to the third placement seat 302 in the same way, and the molding mold 5 continues to be vibrated by the vibration component at the third placement seat 302 so as to fully vibrate and distribute the concrete, thereby improving the subsequent molding effect.

[0064] This application, by setting a first placement seat 3, a second placement seat 301 and a third placement seat 302, can simultaneously perform corresponding operations on three molding molds 5 in different states, thereby improving the efficiency of segment casting.

[0065] The screening assembly includes an annular screening trough 8 rotatably connected to the top of the mixing tank 2. A horizontal screen 801 is fixed in the screening trough 8. The material inlet and the baffle assembly are located on the right side of the screen 801. The top of the inner ring plate of the screening trough 8 is higher than the outer ring plate. The inner ring plate of the screening trough 8 is rotatably connected to the outer side of the drive box 204. A gear ring 802 is fixed to the lower part of the inner side of the inner ring plate. A rotating cylinder 208 is rotatably connected to the middle of the bottom surface of the drive box 204. The rotating cylinder 208 is connected to the stirring shaft 202 through a transmission assembly. A drive gear 207 is fixed to the outer side of the rotating cylinder 208. A transmission gear 206 meshes with the left side of the drive gear 207. A slot is provided on the side wall of the drive box 204. The left side of the transmission gear 206 passes through the slot and meshes with the gear ring 802.

[0066] When the material to be fed directly into the feeding component needs to be fed, the baffle component opens the feed port, the transmission component connects the rotating cylinder 208 to the stirring shaft 202, and through the transmission of the drive gear 207, the transmission gear 206 and the gear ring 802, the screening tank 8 drives the feed port and other structures to rotate, so that the feed port is located at the feed pipe 703. Then the transmission component disengages the rotating cylinder 208 from the stirring shaft 202, and no longer drives the screening tank 8 and the feed port to rotate, so that the material directly enters the mixing tank 2 through the feed port.

[0067] When the material conveyed by the feeding component needs to be screened, the baffle component closes the material inlet, and the transmission component connects the rotating cylinder 208 to the stirring shaft 202. When the stirring shaft 202 rotates, the screening tank 8 and the screen 801 move through the drive gear 207, the transmission gear 206 and the gear ring 802, and the material is evenly distributed on the screen 801. Through the rotation, the material is screened and the screened material enters the mixing tank 2 so that it can be mixed by the rotating stirring shaft 202 and the stirring blades 203.

[0068] Multiple fan-shaped magnet blocks 210 can be evenly fixed along the circumferential direction at the bottom of the outer wall of the rotating cylinder 208, and two arc-shaped electromagnets 209 can be symmetrically fixed on both sides of the bottom of the drive box 204. The outer surface of the magnet block 210 contacts the inner surface of the electromagnet 209. When the screening tank 8 needs to move, the electromagnet 209 is energized and attracts the magnet block 210, thereby fixing the position of the rotating cylinder 208 and thus fixing the position of the screening tank 8, preventing the positions of the screening tank 8 and the material inlet from changing arbitrarily.

[0069] The material blocking assembly includes a baffle 803 located at the material inlet. A vertical arc-shaped lifting plate 804 is fixed to the inner end of the baffle 803. The inner side of the lifting plate 804 is provided with vertical toothed grooves, in which multiple teeth are evenly fixed. A motor box 805 is fixed to the inner ring side plate of the screening tank 8. The motor box 805 is provided with a lifting gear 806 and a motor. A slot is provided on the inner ring side plate. One side of the lifting gear 806 passes through the slot and meshes with the teeth in the toothed groove. When the material inlet needs to be used, the motor causes the lifting gear 806 to rotate, which in turn causes the lifting plate 804 to move the baffle 803 upward, opening the material inlet. When the material inlet rotates to the feed pipe 703, the end of the feed pipe 703 is located between the material inlet and the baffle 803, so that the material can enter the mixing tank 2 directly for mixing without passing through the drying screen.

[0070] The transmission assembly includes multiple first grooves evenly arranged on the inner wall of the rotating cylinder 208 along the circumferential direction. Multiple second grooves are correspondingly provided on the upper part of the outer wall of the stirring shaft 202. A block 901 is provided in both the first groove and the corresponding second groove. A spring rod 902 is fixed to one end of the block 901. The outer end of the spring rod 902 extends out of the rotating cylinder 208 and is fixed with a spring plate 903. A spring is provided between the spring plate 903 and the outer wall of the rotating cylinder 208. Two semi-circular plates 9 are symmetrically arranged on the outer side of the rotating cylinder 208. The end faces of the multiple spring plates 903 are in contact with the inner side of the semi-circular plates 9. Bosses 904 are fixed at both ends of the semi-circular plates 9. A horizontal electric telescopic rod 905 is connected to the outer side of the bosses 904. The outer end of the electric telescopic rod 905 is fixedly connected to the drive box 204.

[0071] When it is necessary to make the rotating drum 208 and the stirring shaft 202 rotate synchronously, the electric telescopic rod 905 drives the boss 904 and the two semicircular plates 9 to move towards the middle, so that the two semicircular plates 9 close together to form a complete annular plate, and drives the spring plate 903 to move inward, so that the spring rod 902 drives the insert block 901 to move. The two ends of the insert block 901 are located in the first groove and the second groove respectively. Thus, when the stirring shaft 202 rotates, the rotating drum 208 rotates synchronously through the limiting effect of multiple insert blocks 901 and the first and second grooves, and then the screening tank 8 rotates through the transmission gear 206, etc.

[0072] Ball bearings can be provided on the outer surface of the spring plate 903 so that the spring plate 903 contacts the inner surface of the semi-circular plate 9 through the ball bearings, thereby reducing the friction between the spring plate 903 and the semi-circular plate 9 when the rotating cylinder 208 rotates and improving the movement flexibility of the rotating cylinder 208.

[0073] Example 2

[0074] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the feeding assembly includes a second base 702 located on the left side of the first base 1. A feeding hopper 701 is fixed on the second base 702. An inclined conveying pipe 7 is fixed at the bottom of the feeding hopper 701. A screw shaft 704 is rotatably connected in the conveying pipe 7. One end of the screw shaft 704 is connected to a motor. An inclined feeding pipe 703 is fixed at the bottom of the upper end of the conveying pipe 7. The bottom end of the feeding pipe 703 is located above the left side of the screening assembly. Materials are added through the feeding hopper 701, and the materials are lifted and fed through the rotating screw shaft 704. The materials are then conveyed to the screening assembly through the feeding pipe 703 for screening or feeding.

[0075] Example 3

[0076] The structure of this embodiment is basically the same as that of Embodiment 1. The difference is that the vibration assembly includes two symmetrically arranged top blocks 4. The bottom end of the top block 4 extends into the drive cavity and is fixed with a vertical moving shaft 401. A horizontal plate 404 is fixed on the inner side wall of the drive cavity. A spring is provided between the top block 4 and the horizontal plate 404. Two fixed cylinders 403 are fixed on the horizontal plate 404. The bottom ends of the two moving shafts 401 pass through the corresponding fixed cylinders 403 and are jointly fixed with a moving plate 402. A plurality of second wheel shafts 406 are evenly provided at the bottom of the moving plate 402. The second wheel shafts 406 are rotatably connected to the drive cavity. One end is connected to a motor, and a plurality of second cams 405 are evenly provided on them. The wheel surface of the second cam 405 contacts the bottom surface of the moving plate 402.

[0077] When the molding die 5 is located on the second placement seat 301 or the third placement seat 302, its bottom contacts the top block 4 on the two vibration components. The motor causes the second wheel shaft 406 to drive multiple second cams 405 to rotate, thereby causing the moving plate 402 to cooperate with the spring, causing the top block 4 to drive the molding die 5 to vibrate, accelerating the uniform distribution of concrete in the molding die 5, and improving the subsequent molding effect.

[0078] The outer ends of multiple second wheel shafts 406 in the same vibration assembly extend out of the drive cavity and are fixed with worm gears 407. The bottoms of the multiple worm gears 407 mesh with a worm 408. The worm 408 is rotatably connected to the outer side of the drive cavity and one end is connected to a motor. The motor causes the worm 408 to rotate, and through the transmission of the worm 408 and the worm gears 407, the multiple second wheel shafts 406 rotate simultaneously to achieve vibration and reduce the number of motors.

[0079] Example 4

[0080] The structure of this embodiment is basically the same as that of embodiment one. The difference is that the vibrating assembly includes a fixed box 6 disposed between two side plates. A first wheel axle is rotatably connected in the fixed box 6. A motor is connected to one end of the first wheel axle. Two first cams 601 are symmetrically fixed on the first wheel axle. An upper pressure plate 602 is provided at the bottom of the first cam 601. The bottom two sides of the upper pressure plate 602 are connected to the bottom surface of the fixed box 6 by springs. A vertical pressure rod 603 is fixed in the middle. The bottom end of the pressure rod 603 extends out of the fixed box 6 and is fixed with a lower pressure plate 604.

[0081] A vertical spring cylinder 503 is fixed on the cover plate 502 at the position corresponding to the lower pressure plate 604. A vibrating block 505 is slidably connected in the spring cylinder 503. A vertical vibrating rod 504 is fixed at the center of the vibrating block 505. The bottom end of the vibrating rod 504 passes through the cover plate 502, and the bottom surface coincides with the bottom surface of the cover plate 502 under the action of the spring. The top end of the vibrating rod 504 extends out of the spring cylinder 503 and is fixed with a contact plate 506.

[0082] When the molding mold 5 is located on the second placement seat 301, the contact plates 506 on the cover plate 502 are all located below the lower pressure plate 604. When the molding mold 5 is being poured, the concrete moves along the arc-shaped bottom surface to both sides of the inner cavity of the molding mold 5. The motor drives the first wheel axle to rotate the first cam 601, thereby causing the upper pressure plate 602, pressure rod 603 and lower pressure plate 604 to move up and down reciprocally, and causing the lower pressure plate 604 to contact the contact plate 506, thereby driving the vibrating block 505 and vibrating rod 504 to vibrate, which plays a certain role in compacting the concrete on both sides of the molding mold 5.

[0083] Electric or pneumatic telescopic rods can be installed on both sides of the top of the fixed box 6, and the fixed box 6 can be connected to the side plate through the telescopic rods, so that the height and position of the fixed box 6 and the lower pressure plate 604 can be adjusted according to the needs of use.

[0084] Example 5

[0085] The structure of this embodiment is basically the same as that of Embodiment 1, except that a limiting groove 509 is provided in the middle of the inner side of the support plate 508 along the vertical direction, and limiting components are correspondingly provided in the second placement seat 301 and the third placement seat 302. The limiting components include a vertical second screw 307 rotatably connected to the center of the inner cavity of the drive cavity. A motor is connected to the bottom end of the second screw 307. An adjusting block 306 is threaded onto the second screw 307. Connecting rods 305 are symmetrically arranged on both sides of the adjusting block 306 and rotatably connected to it. The connecting rods 305 are inclined downwards and outwards, and the outer end rotates... The limit block 303 is dynamically connected. Guide cylinders 304 are provided on the side walls of the second placement seat 301 and the third placement seat 302 respectively. The limit block 303 is slidably connected in the guide cylinder 304 at the corresponding position, and the outer end extends out of the guide cylinder 304 and is correspondingly connected to the limit groove 509. The top of the guide cylinder 304 is provided with a slot corresponding to the position of the connecting rod 305. When the outer ends of the limit block 303 and the connecting rod 305 move relative to the guide cylinder 304, the slot prevents the connecting rod 305 from directly contacting the guide cylinder 304 and hindering the movement of the limit block 303 and other structures.

[0086] When the molding die 5 is placed on the second placement seat 301 or the third placement seat 302, the second screw 307 is rotated by the motor, which causes the adjusting block 306 to move the inner end of the connecting rod 305. This movement of the connecting rod 305 causes the limiting blocks 303 on both sides to extend outward simultaneously through the outer ends of the two connecting rods 305 and be located in the limiting groove 509. The limiting groove 509 and the limiting blocks 303 limit the position of the molding die 5 relative to the second placement seat 301 or the third placement seat 302 when it vibrates, thereby improving the positional accuracy of the molding die 5.

[0087] The outer surface of the limiting block 303 is uniformly provided with multiple balls, which contact the inner surface of the limiting groove 509. When the limiting block 303 and the limiting groove 509 are in contact, the balls reduce the friction between the limiting groove 509 and the limiting block 303, thereby improving the flexibility of the relative movement of the limiting block 303 and the limiting groove 509.
