Description

Technical Field

[0001] The invention relates to the technical field of prefabricated component production, and more specifically to a production line for casting prefabricated concrete components for tunnels. Background Art

[0002] In today's booming tunnel engineering construction field, precast concrete components have become an indispensable key material. With many advantages such as standardized production, controlled quality, and convenient construction, they are widely used in various links such as tunnel lining, portal construction, and invert construction.

[0003] The traditional production method of precast concrete components mostly relies on manual operation, which is not only labor-intensive and inefficient, but also has uneven product quality, making it difficult to meet the increasingly stringent quality requirements of tunnel projects. With the advancement of technology, automated concrete pouring production lines have emerged, such as a small precast component concrete pouring production line disclosed in Chinese Patent Announcement No. CN211662338U, which has brought certain innovations to the industry. It uses a cleverly designed feeding system to achieve the orderly addition of cement, sand, and gravel. At the same time, with the help of a unique mixing structure, the coordinated operation of spiral blades and spiral rods allows the materials to form a circulating flow mixing mode in the barrel, and the spiral rod can also penetrate into the material to finely mix the materials between the spiral blades and around itself, greatly improving the uniformity of mixing and taking the mixing quality of concrete to a new level. In addition, the automated mixing process greatly reduces the burden of manpower and significantly improves mixing efficiency.

[0004] However, an in-depth analysis of the performance of the production line in actual application will reveal that it has limitations that cannot be ignored. In the mixing stage, its mixing range is fixed by the mechanical structure and lacks the necessary flexibility. The performance requirements of concrete precast components used in tunnel engineering construction vary greatly due to differences in geological conditions in different construction sites, changes in engineering design requirements, and different sources of raw material supply. For example, in areas with complex geological conditions and high bearing pressure requirements, concrete needs to have higher strength and density, which requires a more thorough mixing process to ensure that cement, aggregates, etc. are fully integrated; for example, when the particle size and water content of the raw materials fluctuate, the fixed mixing range cannot effectively treat areas with different material accumulation states in a targeted manner. When faced with large and unevenly distributed aggregates, the fixed mixing range makes it difficult to ensure that the materials around the large aggregate particles can also be fully mixed, resulting in weak areas inside the precast components formed by the final casting, which perform poorly in strength tests, and may even cause cracks, peeling and other safety hazards after the tunnel is put into use due to insufficient durability of the components and the inability to withstand external factors such as long-term pressure and water vapor erosion.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a production line for casting precast concrete components for tunnels is provided, in order to achieve a more practical purpose. Summary of the invention

[0035] Technical effects and advantages of the present invention:

[0036] 1. The present invention is provided with a stirring assembly, especially the coordinated cooperation of the first wedge-shaped column, the second wedge-shaped column, the limit slider and the first spring. When the stirring is started, the auxiliary circular plate rotates to prompt the first wedge-shaped column to rotate accordingly, and is squeezed with the inclined surface of the second wedge-shaped column. The limit slider slides in the limit slide groove and the elastic buffering of the first spring, and successfully drives the auxiliary circular plate to move back and forth laterally, thereby driving the stirring rod to achieve reciprocating horizontal stirring; this dynamic stirring mode greatly improves the stirring flexibility; compared with the traditional fixed stirring range, it can adjust the stirring state at any time according to different geological conditions, design requirements and changes in raw materials; when facing complex geology and high-strength concrete, it can ensure that cement and aggregate are fully integrated; when the particle size and water content of the raw materials fluctuate, materials in different stacking states can also be accurately stirred to avoid weak areas in the components, effectively enhance the strength and durability of prefabricated components, and provide solid guarantee for the quality of tunnel engineering.

[0037] 2. The internal gear of the present invention is firmly fixed on the inner wall of the mixing drum, building a solid foundation for the entire mixing transmission system. The pinion is precisely meshed with it, and its thickness is adjusted to half of the internal gear, which not only ensures the meshing accuracy but also reserves ample operating space; one end of the auxiliary shaft is tightly connected to the pinion, and the other end is flexibly connected with the auxiliary circular plate with the help of a bearing; when the mixing operation is started, the auxiliary circular plate rotates instantly to drive the auxiliary shaft to rotate synchronously, thereby prompting the mixing rod to start its own rotation mode; this design enhances the mixing force and makes material mixing more efficient; when faced with different concrete viscosity requirements for different projects, whether high or low viscosity, the strong mixing force can ensure that various materials are fully blended, avoiding concrete performance defects caused by uneven mixing, and providing concrete with uniform texture and excellent performance for key links such as tunnel lining and portal construction, strongly supporting the high-quality construction of tunnel projects.

[0038] 3. In the present invention, multiple magnetic blocks distributed in a circular array are firmly embedded in the circular groove on the side of the inner gear, and continuously emit stable magnetic force; the connecting rod at the end of the stirring rod is made of iron material that is easily attracted by magnets. As the stirring rod rotates, the connecting rod gradually approaches the magnetic block, and a strong magnetic attraction effect is instantly generated between the two; under the pull of the magnetic force, the angle of the stirring rod changes. At the same time, the second spring outside the pin cleverly cooperates, and with its perfect elastic recovery force, it helps the stirring rod to achieve flexible reciprocating angle changes; in this way, internal porosity and local weak strength caused by uneven mixing are effectively avoided, and the density and overall strength of the prefabricated components are greatly improved, so that it can better withstand the harsh external conditions such as pressure and water vapor erosion that the tunnel faces for a long time after it is put into use, effectively extending the service life of the tunnel and safeguarding the durability of the tunnel project.

[0059] A stirring assembly 9 is disposed through the stirring drum 1;

[0060] The driving assembly 10 is arranged inside the mixing drum 1. The driving assembly 10 is installed on the inner wall of the mixing drum 1 and is connected to the mixing assembly 9.

[0061] The micro-switching part 11 is disposed inside the mixing drum 1 , and the micro-switching part 11 is connected to the driving assembly 10 .

[0062] The stirring assembly 9 comprises:

[0063] The motor 91 is arranged at the left side of the mixing drum 1;

[0064] The connecting shaft 92 is disposed inside the mixing drum 1, and the left end of the connecting shaft 92 is fixedly mounted to the coupling of the motor 91;

[0065] The auxiliary circular plate 93 is slidably mounted on the outer wall of the connecting shaft 92 , and the auxiliary circular plate 93 is connected to the connecting shaft 92 via a connecting portion 94 .

[0066] In the specific implementation process, the coupling can be driven to rotate the connecting shaft 92 by starting the motor 91. The auxiliary circular plate 93 is connected to the connecting shaft 92 through the connecting part 94, so the auxiliary circular plate 93 can rotate when the connecting shaft 92 rotates, and finally the stirring work of the stirring rod 113 can be realized.

[0067] In this embodiment, the lower surface of the motor 91 is fixedly mounted on the motor base 7, and a support frame 6 is fixedly mounted on the bottom surface of the motor base 7. The end surface of the support frame 6 is fixedly mounted on the left side surface of the mixing drum 1, and a second leg 8 is fixedly mounted on the bottom surface of the support frame 6. The second leg 8 is fixedly mounted on the first leg 5 through a cross frame. The motor 91 can be firmly mounted through the installed motor base 7 to facilitate the normal operation of the motor 91. The stable installation can be enhanced by installing the support frame 6 and the second leg 8 at the bottom of the motor base 7. The first wedge column 941 can rotate under the rotation of the auxiliary circular plate 93, and then be squeezed with the second wedge column 942. Under the setting of the limiting slider 943 and the first spring 944, the reciprocating movement of the auxiliary circular plate 93 can be realized. The final reciprocating movement of the stirring rod 113 can be realized under the reciprocating motion of the auxiliary plate 93, so that it is fully stirred.

[0068] Further, the connecting portion 94 includes:

[0069] The limiting slide block 943 is slidably arranged with the limiting slide groove 945 provided on the outer wall of the connecting shaft 92;

[0070] A first spring 944 is disposed in the limiting slide groove 945, one end of the first spring 944 is fixedly mounted to the inner wall of the limiting slide groove 945, and the other end of the first spring 944 is fixedly mounted to the end surface of the limiting slide block 943;

[0071] A first wedge-shaped column 941 is slidably sleeved on the outer wall of the connecting shaft 92, and a left end surface of the first wedge-shaped column 941 is fixedly mounted on a right side surface of the auxiliary circular plate 93;

[0072] The second wedge-shaped column 942 is slidably sleeved on the outer wall of the connecting shaft 92, the right end face of the second wedge-shaped column 942 is fixedly installed on the inner wall of the mixing drum 1, and the left end face of the second wedge-shaped column 942 is contacted with the right end face of the first wedge-shaped column 941. Here, the surfaces where the first wedge-shaped column 941 and the second wedge-shaped column 942 contact each other are both inclined surfaces, so that the first wedge-shaped column 941 can be extruded with the second wedge-shaped column 942 during rotation, and the first wedge-shaped column 941 can have a moving tendency.

[0073] In this embodiment, a stirring assembly 9 is provided, especially the first wedge column 941, the second wedge column 942, the limit slider 943 and the first spring 944 cooperate with each other.

[0074] Embodiment 2: Based on the above embodiment, the driving assembly 10 includes:

[0075] The outer wall of the internal gear 101 is fixedly mounted on the inner wall of the mixing drum 1;

[0076] A pinion 102 meshing with the inner gear 101;

[0077] The thickness of the pinion 102 is half of the thickness of the inner gear 101, so that there is enough meshing space between the pinion 102 and the inner gear 101;

[0078] The outer wall of the left end of the auxiliary shaft 103 is fixedly installed with the inner wall of the pinion 102, and the right end of the auxiliary shaft 103 is rotatably arranged with the left side surface of the auxiliary circular plate 93 through a bearing.

[0079] In the specific implementation process, since the auxiliary shaft 103 is rotatably arranged with the auxiliary circular plate 93 through the bearing, the auxiliary shaft 103 will rotate together with the auxiliary circular plate 93. When the auxiliary shaft 103 rotates, the small gear 102 installed at the end of the auxiliary shaft 103 can rotate. Due to the internal gear 101, the auxiliary shaft 103 will form its own rotation at this time, so that the stirring rod 113 has its own rotation stirring movement tendency, thereby enhancing the stirring force.

[0080] When the mixing operation is started, the auxiliary circular plate 93 rotates instantly, driving the auxiliary shaft 103 to rotate synchronously, thereby prompting the mixing rod 113 to start its own rotation mode; this design enhances the mixing force and makes material mixing more efficient; when faced with different concrete viscosity requirements for different projects, whether high or low viscosity, the strong mixing force can ensure that all materials are fully blended, avoiding concrete performance defects caused by uneven mixing, and providing concrete with uniform texture and excellent performance for key links such as tunnel lining and portal construction, strongly supporting the high-quality construction of tunnel projects.

[0081] Embodiment 3: Based on the above embodiment, the micro-actuating part 11 includes:

[0082] There are multiple magnetic blocks 111, and the multiple magnetic blocks 111 are fixedly installed in an annular groove 12 opened on the side of the internal gear 101 in an annular array;

[0083] The mounting block 114 is fixedly mounted on the outer wall of the auxiliary shaft 103. The mounting block 114 is movably connected to the stirring rod 113 through the latch 115. The end of the stirring rod 113 away from the outer wall of the auxiliary shaft 103 is fixedly mounted with a connecting rod 112. The end of the connecting rod 112 that is close to the magnetic block 111 is made of iron. In this way, the connecting rod 112 can be attracted by the magnetic block 111 during the rotation process, so that the connecting rod 112 can drive the stirring rod 113 to move, so that the stirring rod 113 changes its angle, so that the stirring is more dense;

[0084] The second spring 116 is sleeved on the outer wall of the latch 115 , one end of the second spring 116 is fixedly mounted on the surface of the mounting block 114 , and the other end of the second spring 116 is fixedly mounted on the surface of the stirring rod 113 .

[0085] In the specific implementation process, the connecting rod 112 will rotate during the rotation of the stirring rod 113. When the connecting rod 112 rotates to get close to the magnetic block 111, suction will be generated. The suction can make the connecting rod 112 have a pulling effect. The pulling can make the angle of the stirring rod 113 change. Under the action of the second spring 116, the angle of the stirring rod 113 can be changed back and forth, making the stirring more dense and enhancing the stirring and mixing effect. The multiple magnetic blocks 111 distributed in an annular array are firmly embedded in the annular groove on the side of the inner gear 101, and continuously emit stable magnetic force. The connecting rod 112 at the end of the stirring rod 113 is made of iron material that is easily attracted by magnets. 113 rotates by itself, and the connecting rod 112 gradually approaches the magnet, and a strong magnetic attraction effect is instantly generated between the two; under the pull of the magnetic force, the angle of the stirring rod 113 changes. At the same time, the second spring 116 outside the pin 115 cooperates cleverly, and with its perfect elastic recovery force, it helps the stirring rod 113 to achieve flexible reciprocating changes in angle; in this way, the internal porosity and local weakness caused by uneven mixing are effectively avoided, and the density and overall strength of the prefabricated components are greatly improved, so that it can better withstand the harsh external conditions such as pressure and water vapor erosion that the tunnel will face for a long time after it is put into use, effectively extending the service life of the tunnel and safeguarding the durability of the tunnel project.

[0086] Working principle: When the production process of precast concrete components for tunnel engineering is started, the first step is to put in the raw materials. All kinds of raw materials required for the preparation of precast components are accurately put into the internal space of the mixing drum 1 through the feed pipe 2 according to the established process. After all the raw materials are put in, the power drive link is immediately started, that is, the motor 91 is started. After the motor 91 is running, it drives the connecting shaft 92 to rotate rapidly with the help of the coupling, which is a key connecting part.

[0087] Since the inner wall of the circular auxiliary plate 93 is tightly connected to the limit slider 943 in a fixed installation manner, and the limit slider 943 is slidably set in the limit slide groove 945 opened on the outer wall of the connecting shaft 92, such an ingenious structure makes it possible for the circular auxiliary plate 93 to rotate closely along with the connecting shaft 92 at the moment the connecting shaft 92 rotates.

[0088] As the circular auxiliary plate 93 rotates, the first wedge-shaped column 941 fixedly connected thereto also starts to rotate. At this time, because the second wedge-shaped column 942 is fixed to a specific position on the inner wall of the mixing drum 1 and is in close contact with the first wedge-shaped column 941, the contact surfaces of the two are specially designed with an inclined surface, and the elastic buffering and reset effect provided by the first spring 944 causes the first wedge-shaped column 941 to reciprocate under the mutual squeezing with the second wedge-shaped column 942 during the rotation process. This reciprocating movement is further transmitted to the circular auxiliary plate 93, giving it the characteristic of lateral reciprocating movement. Ultimately, the result of this series of action linkage is that the stirring rod 113 in the tiny toggle portion 11 is driven, and has a tendency to stir laterally and reciprocally, so that the material can be stirred laterally over a large area and with high efficiency.

[0089] At the same time, during the rotation of the circular auxiliary plate 93, the auxiliary shaft 103 connected to it through the bearing will also be driven to rotate synchronously. A pinion 102 is fixedly installed on the outer wall of the left end of the auxiliary shaft 103, and the inner gear 101 fixed on the inner wall of the mixing drum 1 meshes with the pinion 102, and the thickness of the pinion 102 is carefully designed to be half the thickness of the inner gear 101, leaving just the right meshing space to ensure that the two fit together seamlessly. Based on such a gear transmission structure, when the auxiliary shaft 103 rotates, under the coordinated cooperation of the pinion 102 and the inner gear 101, the auxiliary shaft 103 itself will produce additional rotation, which is transmitted to the mounting block 114, driving it to rotate, thereby making the stirring rod 113 have its own rotation and stirring tendency, achieving deep stirring of the material, and ensuring that the material can also be fully mixed in the vertical direction.

[0090] Moreover, when the stirring rod 113 is rotating, the connecting rod 112 at its end is made of iron material that is easily attracted by magnets. As the stirring rod 113 gradually rotates and approaches the magnetic block 111 fixed in the annular groove on the side of the inner gear 101, a strong magnetic attraction trend will be generated between the two. Under the pull of the magnetic force, the angle of the stirring rod 113 begins to change. What is particularly critical is that the second spring 116 mounted on the outer wall of the latch 115, with its own precisely adjusted elasticity, provides a reverse force in a timely manner during the process of the magnetic force pulling the stirring rod 113 to change its angle, thereby helping the stirring rod 113 to achieve a reciprocating change in angle. In this way, the stirring rod 113 can finely move the material from multiple angles, making the material mixing more even and thorough.

[0091] In summary, through the coordinated efforts of the three mixing modes of the mixing rod 113, namely, the lateral reciprocating mixing, the self-rotating mixing, and the reciprocating angle change, the final mixing force and effect are enhanced in all directions and at multiple levels, effectively meeting the high-quality requirements of the tunnel project for the strength, density and other aspects of precast concrete components, laying a solid foundation for tunnel construction, and ensuring the long-term stability and safe operation of the tunnel project.
