Abstract
Description
Technical Field
[0001] This invention relates to the field of building engineering technology, specifically to a wedge-shaped block longitudinal and transverse slope adjuster. Background Technology
[0002] When constructing precast beam wedge blocks, precise control of their longitudinal and transverse slopes is crucial to ensure that the geometric dimensions and installation accuracy of the precast beam meet design requirements. Traditionally, the longitudinal and transverse slopes of wedge blocks are adjusted using a four-point elevation control method, which controls the slopes by adjusting the elevations of the four corner points of the wedge block's bottom formwork. Two common solutions exist: one uses quartz sand mixed with mortar for height adjustment, and the other uses a steel formwork base with bolts for elevation adjustment. While this four-point elevation control method achieves basic slope adjustment in actual construction, the process requires repeated measurement and adjustment of the elevations of the four corner points, and it is difficult to guarantee the cross-centering accuracy of the wedge blocks.
[0003] However, the existing four-corner elevation control methods have significant drawbacks: the use of quartz sand and mortar is prone to formwork displacement during concrete pouring due to high-frequency vibration or concrete impact, making it difficult to guarantee the accuracy of longitudinal and transverse slopes; while the use of steel formwork bases with bolts provides better stability, it is prone to planar position deviations during adjustment, and the adjustment process of the four corner elevations is cumbersome and complex, requiring repeated measurements and corrections, resulting in low work efficiency. Summary of the Invention
[0004] The purpose of this invention is to solve the problems of cumbersome adjustment of the longitudinal and transverse slopes of wedge blocks, unreliable locking mechanisms, and easy mold running that leads to low accuracy in the existing technology, and to propose a wedge block longitudinal and transverse slope adjuster.

Each adjusting block includes a longitudinal slope adjusting part for longitudinal slope adjustment and a transverse slope adjusting part for transverse slope adjustment. The longitudinal slope and transverse slope of the wedge block are adjusted by rotating the directional shafts.

Hydraulic oil on both sides of the piston body flows through the through holes. A limiting plug is disposed on the other side surface of the piston body. The limiting plug is used to selectively block the through hole to limit the hydraulic oil volume on both sides of the piston body and lock the rod body.
[0011] Furthermore, the limiting plug includes: A fixing block is fixedly installed on the surface of the piston body away from the rod. The groove is formed on the side surface of the fixing block near the rod. Electromagnet, fixedly installed inside the tank; An elastic element, one end of which is disposed on the surface of an electromagnet, and the other end of which is disposed on a lifting rod, the other end of which is fixedly connected to a piston body.
[0012] Furthermore, an O-ring is provided in the groove, and the lifting rod passes through the center of the O-ring. The groove and the lifting rod are sealed together by the O-ring.

[0016] Compared with the prior art, the technical solution of this application has the following beneficial technical effects: This invention employs a structure combining a central positioning shaft with a wedge-shaped bottom mold steel plate, fundamentally ensuring the cross-alignment accuracy of the wedge blocks and avoiding the planar position deviation problem easily caused by traditional four-legged elevation adjustment methods. Secondly, by circumferentially distributing several directional shafts around the outer periphery of the wedge-shaped bottom mold steel plate and fixing adjustment blocks at the outer ends of the directional shafts, independent adjustment mechanisms for the longitudinal slope and transverse slope adjustment sections are formed. This allows for precise control of the longitudinal and transverse slopes through the rotation of the directional shafts. A telescopic support rod is installed between the adjustment block and the wedge-shaped bottom mold steel plate. This telescopic support rod consists of a rod body and a cylinder filled with hydraulic oil.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0020] Combination Figures 1-8 As shown, a wedge-shaped block longitudinal and transverse slope adjuster of the present invention includes a central positioning shaft 1 and a wedge-shaped block bottom mold steel plate 2 disposed on the central positioning shaft 1, and further includes: The directional shaft 3 is circumferentially distributed on the outer periphery of the wedge-shaped bottom mold steel plate 2, and the directional shaft 3 can rotate circumferentially relative to the wedge-shaped bottom mold steel plate 2; Adjusting blocks 4 are fixedly installed on the outer ends of each directional shaft 3. Adjusting blocks 4 include a longitudinal slope adjustment part for longitudinal slope adjustment and a transverse slope adjustment part for transverse slope adjustment. The longitudinal slope and transverse slope of the wedge block are adjusted by rotating the directional shaft 3. Telescopic support rods 5 are respectively set between each adjusting block 4 and the wedge-shaped block bottom mold steel plate 2. The telescopic support rods 5 include rod body 51 and cylinder body 52. One end of rod body 51 is telescopically inserted into cylinder body 52. Hydraulic oil is provided inside cylinder body 52. Equalizers 6 are respectively installed at the ends of each rod 51 that extend into the cylinder 52. Equalizers 6 are used to adjust the distribution of hydraulic oil in the cylinder 52 in order to limit and lock the position of the adjusting block 4.
[0021] The central positioning shaft 1, in conjunction with the wedge-shaped bottom mold steel plate 2, achieves cross-center positioning of the wedge-shaped block, avoiding planar position deviation. The directional shaft 3 rotates circumferentially relative to the wedge-shaped bottom mold steel plate 2, driving the adjusting block 4 to achieve independent adjustment of the longitudinal slope adjustment section and the transverse slope adjustment section, allowing the longitudinal slope and transverse slope to be precisely controlled separately. The rod 51 in the telescopic support rod 5 can extend and retract within the cylinder 52, and works with the hydraulic oil within the cylinder 52 to achieve height adjustment and support. The equalizer 6 controls the flow of hydraulic oil on both sides of the piston body by adjusting the distribution of hydraulic oil within the cylinder 52, thereby limiting and locking the position of the adjusting block 4, preventing formwork slippage due to vibration or impact during concrete pouring, and ensuring the accuracy and stability of longitudinal and transverse slope adjustment.
[0022] In a preferred embodiment, the present invention may be further configured as follows: Figure 1 , Figure 3 As shown, there are no fewer than four directional axes 3, with two opposite axes forming the longitudinal slope adjustment section and the other two opposite axes forming the transverse slope adjustment section. The number and distribution of the adjustment blocks 4 are adapted to the directional axes 3. Each adjustment block 4 is equipped with no fewer than two telescopic support rods 5. There are no fewer than four directional axes 3, with two opposite axes 3 serving as the longitudinal slope adjustment section and the other two opposite axes 3 serving as the transverse slope adjustment section, forming independent adjustment systems for the longitudinal and transverse slopes. Each adjustment block 4 is equipped with no fewer than two telescopic support rods 5, which distribute the load through multi-point support, enhancing the load-bearing capacity and stability of the adjustment block 4 and avoiding deformation or instability caused by single-point stress.
[0023] In a preferred embodiment, the present invention may be further configured as follows: Figure 3 , Figure 5 As shown; a number of drive components 7, whose distribution positions are adapted to the orientation shaft 3, are fixedly installed on the surface of the wedge-shaped block bottom mold steel plate 2 near the central positioning shaft 1. Drive component 7 includes: The drive motor 71 is fixedly installed on the side surface of the wedge-shaped block bottom mold steel plate 2 near the central positioning shaft 1, wherein the number and distribution of the drive motor 71 are adapted to the orientation shaft 3; The active synchronous pulley 72 is fixedly mounted on the output end of the drive motor 71; Driven synchronous pulley 73 is fixedly installed on the outside of directional shaft 3; The transmission timing belt 74 is located outside the driving timing pulley 72 and the driven timing pulley 73. The drive motor 71 drives the transmission timing belt 74 to move through the driving timing pulley 72. The transmission timing belt 74 drives the driven timing pulley 73 to rotate. The driven timing pulley 73 drives the directional shaft 3 to rotate circumferentially, realizing the automatic adjustment of the adjusting block 4. The timing belt transmission method ensures the accuracy and synchronization of the transmission, avoids the tedious process of repeated measurement and correction in the traditional manual adjustment method, and improves the adjustment efficiency and accuracy.
[0024] In a preferred embodiment, the present invention may be further configured as follows: Figure 1 , Figure 2 As shown; a first hinge seat 8 is fixedly installed on each of the two opposite sides of the adjusting block 4. A first hinge block 81 is hinged to the inner side of the first hinge seat 8. Two second hinge seats 9 are fixedly installed on each side of the wedge-shaped block bottom mold steel plate 2. A second hinge block 91 is hinged to the inner side of the second hinge seat 9. The other end of the rod 51 is fixedly connected to the first hinge block 81. The fixed end of the cylinder 52 is fixedly connected to the second hinge block 91. The first hinge seat 8 and the first hinge block 81 form a hinge connection. The second hinge seat 9 and the second hinge block 91 form a hinge connection. The rod 51 is hinged to the adjusting block 4 through the first hinge block 81. The cylinder 52 is hinged to the wedge-shaped block bottom mold steel plate 2 through the second hinge block 91. The hinge structure allows the telescopic support rod 5 to change angle when it rotates with the directional shaft 3 during the adjustment process, adapting to the change in spatial position caused by the change in the height of the adjusting block 4, and avoiding stress concentration or jamming caused by rigid connection.
[0025] In a preferred embodiment, the present invention may be further configured as follows: Figure 6 , Figure 7 As shown; Equalizer 6 includes: Piston body 61 is fixedly installed at the end of rod 51 that extends into cylinder 52, and the outer wall of piston body 61 is in contact with the inner wall of cylinder 52. Through holes 62 are provided along the thickness direction of piston body 61. There are several of them and they are distributed in a ring at equal intervals along the central axis of piston body 61. Hydraulic oil on both sides of piston body 61 flows through through holes 62. A limiting plug 63 is disposed on the other side surface of the piston body 61. The limiting plug 63 is used to selectively block the through hole 62 to limit the hydraulic oil volume on both sides of the piston body 61, thereby locking the rod 51. The outer wall of the piston body 61 is in sealed contact with the inner wall of the cylinder 52, dividing the interior of the cylinder 52 into two hydraulic oil chambers. The through hole 62 penetrates the piston body 61, allowing hydraulic oil to flow on both sides under normal conditions, so that the rod 51 can freely extend and retract within the cylinder 52 to achieve height adjustment. After the limiting plug 63 selectively blocks the through hole 62, it blocks the flow of hydraulic oil on both sides, using the incompressible property of hydraulic oil to lock the position of the rod 51, thereby reliably locking the adjusting block 4 and preventing position changes under external force.
[0026] In a preferred embodiment, the present invention may be further configured as follows: Figure 6 , Figure 7 As shown; the limiting plug 63 includes: The fixing block 631 is fixedly installed on the side surface of the piston body 61 away from the rod body 51; The groove 632 is formed on the surface of the fixing block 631 near the rod 51; Electromagnet 633 is fixedly installed inside the tank 632; The elastic element 634 has one end attached to the surface of the electromagnet 633, and the other end is equipped with a lifting rod 635. The other end of the lifting rod 635 is fixedly connected to the piston body 61. Under normal conditions, the elastic element 634 is in its natural state, the lifting rod 635 retracts into the groove 632, and the end face of the fixing block 631 abuts against the piston body 61, blocking the through hole 62. At this time, hydraulic oil cannot flow, achieving a locked state. When adjustment is required, the electromagnet 633 is energized to generate electromagnetic force, which overcomes the elastic force of the elastic element 634 and pushes the lifting rod 635 out of the groove 632, causing the fixing block 631 to separate from the piston body 61. The through hole 62 opens, and hydraulic oil flows through the through hole 62 and the gap around the fixing block 631, allowing the rod body 51 to extend and retract for adjustment. After the electromagnet 633 is de-energized, the elastic element 634 rebounds, causing the lifting rod 635 to retract, and the fixing block 631 abuts against the piston body 61 again, achieving automatic locking.
[0027] In a preferred embodiment, the present invention may be further configured as follows: Figure 7 , Figure 8As shown; an O-ring seal is provided inside the groove 632, and the lifting rod 635 passes through the center of the O-ring seal. The groove 632 and the lifting rod 635 are sealed together by the O-ring seal. Soft magnetic sealing rings 10 are embedded on the surfaces of the fixed block 631 and the piston body 61 that are close to each other. The two soft magnetic sealing rings 10 adhere to each other and seal. The O-ring seal forms a dynamic seal between the groove 632 and the lifting rod 635, preventing hydraulic oil from flowing out between the lifting rod 635 and the groove 632. To prevent leakage at the fitting gap of 2, soft magnetic sealing rings 10 are respectively embedded in the contact surfaces of the fixed block 631 and the piston body 61. The two soft magnetic sealing rings 10 are attracted to each other by magnetic force, which enhances the sealing effect between the fixed block 631 and the piston body 61, prevents hydraulic oil from leaking from the contact surface, and improves the reliability and sealing performance of locking. It should also be noted that the diameter of the fixed block 631 is smaller than the diameter of the piston body 61, so that hydraulic oil can flow through the through hole 62 and the gap on the outer periphery of the fixed block 631.
[0028] In a preferred embodiment, the present invention may be further configured as follows: Figure 7 , Figure 8 As shown, a conical protrusion 11 is fixedly installed on the side surface of the fixing block 631 near the piston body 61. A recessed groove 12 that matches the shape and size of the conical protrusion 11 is provided on the side surface of the piston body 61 near the fixing block 631. The conical protrusion 11 is inserted into the recessed groove 12 to form a guide and positioning, so that the fixing block 631 and the piston body 61 are precisely aligned. At the same time, the conical surface structure of the conical protrusion 11 avoids the formation of a flat liquid space on the side surface of the fixing block 631 near the piston body 61, preventing hydraulic oil from accumulating and remaining on this surface, ensuring that the fixing block 631 and the piston body 61 can fit tightly, improving the sealing effect and locking performance.
[0029] In a preferred embodiment, the present invention may be further configured as follows: Figure 2 , Figure 5 As shown, a circular hole 13 is provided at the center of the directional shaft 3. A fixing rod 14 located in the circular hole is fixedly installed on the outer periphery of the wedge-shaped bottom mold steel plate 2. An angle scale 15 is fixedly installed on the side surface of the fixing rod 14 away from the wedge-shaped bottom mold steel plate 2. An indicator rod 16 is fixedly installed on the outer surface of the adjusting block 4 along its axial direction. The indicating end of the indicator rod 16 is aligned with the angle scale 15. The fixing rod 14 remains fixed relative to the wedge-shaped bottom mold steel plate 2, and the angle scale 15 remains stationary with the fixing rod 14. The indicator rod 16 rotates synchronously with the adjusting block 4 and the directional shaft 3. The indicating end of the indicator rod 16 indicates the current rotation angle on the angle scale 15. By reading the position of the indicator rod 16 on the angle scale 15, the rotation angle of the directional shaft 3 can be displayed intuitively, facilitating precise control of the adjustment amount of the longitudinal slope and cross slope, realizing visual adjustment, and improving adjustment accuracy.
[0030] In a preferred embodiment, the present invention may be further configured as follows: Figure 1 , Figure 3 As shown, the geometric shape of the central positioning shaft 1 can be one of the following: a solid cylinder, a hollow cylinder, a hollow square column, a solid square column, a triangular prism, or a hexagonal prism. The central positioning shaft 1 can adopt various geometric shapes such as solid cylinder, hollow cylinder, hollow square column, solid square column, triangular prism, or hexagonal prism. Different shapes of the central positioning shaft 1, when combined with the wedge-shaped block bottom mold steel plate 2, can all achieve the central positioning function of the wedge block. The multiple shape options increase the adaptability and flexibility of the structure. A suitable shape of the central positioning shaft 1 can be selected according to actual construction needs, load-bearing requirements, or installation conditions to meet the needs of different application scenarios.
[0031] Furthermore, a lifting plate 17 is provided above the wedge-shaped bottom mold steel plate 2. The lifting plate 17 has at least four guide posts 18 that penetrate the wedge-shaped bottom mold steel plate 2 on one side surface. At the same time, the end of the adjusting block 4 is in contact with the surface of the lifting plate 17. By adjusting the position of the adjusting block 4, the position of the lifting plate 17 relative to the top of the wedge-shaped bottom mold steel plate 2 is moved. During the movement of the lifting plate 17, the guide posts 18 ensure its stability during vertical movement.
[0032] The specific working principle of the wedge-shaped block longitudinal and transverse slope adjuster of the present invention is as follows: When using it, first position the wedge block bottom mold steel plate 2 by cross-aligning it through the central positioning shaft 1 to ensure that the planar position of the wedge block is accurate and without deviation. In the initial state, the electromagnet 633 is de-energized, the elastic element 634 causes the lifting rod 635 to retract into the groove 632, the end face of the fixing block 631 is in close contact with the piston body 61, the soft magnetic sealing rings 10 enhance the sealing effect by magnetic attraction, the conical protrusion 11 is inserted into the recessed groove 12 to achieve precise centering, at this time the through hole 62 is completely blocked, the hydraulic oil chambers on both sides of the cylinder 52 are isolated from each other, and the telescopic support rod 5 is in the locked state; When longitudinal or transverse slope adjustment is required, the electromagnet 633 is energized first. The electromagnetic force overcomes the elastic force of the elastic element 634 and pushes the lifting rod 635 out of the groove 632, causing the fixed block 631 to separate from the piston body 61. The through hole 62 is opened, and hydraulic oil can flow freely through the through hole 62 and the gap on the outer periphery of the fixed block 631 on both sides of the piston body 61. At this time, the rod 51 can freely extend and retract inside the cylinder 52. Then the drive motor 71 is started. The drive motor 71 drives the transmission synchronous belt 74 to move through the active synchronous belt pulley 72. The transmission synchronous belt 74 drives the driven synchronous belt pulley 73 to rotate, thereby causing the directional shaft 3 to rotate circumferentially relative to the wedge block bottom mold steel plate 2. According to the adjustment requirements, the two opposite directional shafts 3 can be operated as the longitudinal slope adjustment part for longitudinal slope adjustment, or the other two opposite directional shafts 3 can be operated as the transverse slope adjustment part for transverse slope adjustment. When the directional shaft 3 rotates, it drives the adjusting block 4 fixed at its outer end to rotate synchronously. The indicator rod 16 rotates with the adjusting block 4 and indicates the current rotation angle on the angle scale 15. The operator can achieve visual adjustment by reading the position of the indicator rod 16 on the angle scale 15 and accurately control the adjustment amount. The rotation of the adjusting block 4 is transmitted to the telescopic support rod 5 through the hinge structure. The rod body 51 is hinged to the adjusting block 4 through the first hinge block 81, and the cylinder body 52 is hinged to the wedge-shaped block bottom mold steel plate 2 through the second hinge block 91. The hinge structure allows the telescopic support rod 5 to adaptively adjust its posture as the angle changes during the adjustment process, thus avoiding stress concentration. Each adjusting block 4 is equipped with no less than two telescopic support rods 5, which distribute the load through multi-point support, thereby enhancing the load-bearing capacity and stability. When adjusted to the target longitudinal and transverse slope positions, the power supply of the electromagnet 633 is cut off, the elastic element 634 rebounds and the lifting rod 635 retracts, the fixing block 631 re-closes tightly with the piston body 61, the through hole 62 is blocked, and the hydraulic oil chambers on both sides inside the cylinder 52 are isolated again. The incompressible properties of the hydraulic oil are used to reliably lock the position of the rod body 51, thereby fixing the adjusting block 4 in the set position, and thus driving the lifting plate 17 to move through the adjusting block 4. Once locked, the entire wedge block longitudinal and transverse slope adjuster can withstand high-frequency vibration and concrete impact during the concrete pouring process, effectively preventing formwork slippage, ensuring high precision and stability of the wedge block's longitudinal and transverse slopes, and meeting the quality requirements of precast beam construction.
