Description

Technical Field

[0001] This invention relates to the field of slope construction technology, specifically to an auxiliary positioning device for prefabricated formwork used in slope construction. Background Technology

[0002] Prefabricated formwork is a commonly used construction component in slope protection engineering. It involves assembling and fixing prefabricated formwork on-site to the slope surface, followed by pouring concrete to form a protective structure. Compared to traditional loosely assembled formwork, prefabricated formwork offers advantages such as faster construction speed, higher formwork turnover rate, and better forming quality, and is widely used in slope treatment projects in highways, water conservancy, and construction. During the installation of prefabricated formwork, the joints between adjacent formwork sections need to be precisely aligned and temporarily fixed to prevent misalignment, gaps, or grout leakage during concrete pouring. Currently, on construction sites, manual support, simple clamps, or temporary support rods are typically used to position the formwork joints. Operators judge the verticality and flatness of the formwork based on experience, and then initially tighten it with bolts or wedges.

[0003] However, existing prefabricated formwork positioning methods have significant shortcomings in practical applications. First, slope surfaces typically have an inclination angle, and the slope may vary in different sections. Traditional manual support or simple clamps cannot adapt to the actual slope angle, leading to relative slippage or angular deviations between formwork sections after positioning, affecting the tightness of the formwork joints and the overall alignment. Second, the lack of reliable clamping force and continuous locking function during positioning means that the lateral pressure generated during concrete pouring may cause the formwork joints to open, resulting in grout leakage and honeycomb-like pitting on the concrete surface. Rework increases the construction period and cost. Summary of the Invention

[0014] This invention provides an auxiliary positioning device for prefabricated formwork used in slope construction. It has the following advantages: I. The prefabricated formwork auxiliary positioning device for slope construction, by setting an angle limiting mechanism, can adapt to the actual tilt angle of the slope and lock the angle after work, thereby ensuring that the positioning mechanism always keeps parallel and in contact with the formwork surface, and preventing positioning deviation during the installation of prefabricated formwork.

[0015] II. The prefabricated formwork auxiliary positioning device for slope construction, through the setting of a drive mechanism, can generate linear thrust, push the internal components to move smoothly, thereby triggering the clamping action of the positioning mechanism, and simultaneously controlling the locking state of the angle limit mechanism.

[0016] 3. The prefabricated formwork auxiliary positioning device for slope construction uses a positioning mechanism to form a high-friction contact between the components and the formwork surface. At the same time, under the drive of the drive mechanism, a stable clamping force is applied to the connection of the two prefabricated formworks to prevent the formwork from misaligning or opening during concrete pouring.

[0017] IV. This prefabricated formwork auxiliary positioning device for slope construction uses an internally threaded tube as the linear motion actuator of the drive mechanism. The internal thread engages with the drive end of the drive mechanism to convert rotational motion into linear movement. A sliding rod moves with the internally threaded tube to trigger the locking or unlocking of the angle limit mechanism and transmits the driving force to the positioning mechanism. A connecting block rigidly connects the internally threaded tube and the sliding rod, ensuring synchronous movement.

[0018] V. The prefabricated formwork auxiliary positioning device for slope construction, through the installation of a first piston, moves up and down within a transfer box under pressure, driving the support frame and sliding column to rise and fall synchronously. A second spring tube provides an upward reset force to the sliding column; when the pressure medium is released, the locking strip automatically lifts, releasing the lock on the sliding rod. The locking strip, fixed to the bottom of the sliding column, engages with a positioning groove on the upper surface of the sliding rod. When the locking strip is inserted downwards into the positioning groove, the sliding rod is locked in its current position, thus maintaining continuous pressure from the positioning plate on the formwork. Multiple positioning grooves provide multiple locking positions to accommodate different formwork thicknesses and pressure requirements. Attached Figure Description

[0021] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0022] Figures 1-12 As shown, the present invention provides a technical solution: a prefabricated formwork auxiliary positioning device for slope construction, comprising a base plate 1 and a connecting box 2, and a connecting plate 3 fixed to the outer surface of the connecting box 2. By setting the base plate 1, it serves as the basic support for the entire positioning device, contacting the slope surface during use to distribute pressure and maintain overall stability. The device also includes... An angle limiting mechanism 4 is fixed to the lower surface of the connecting box 2, which is located directly above the base plate 1. By setting the angle limiting mechanism 4, the actual tilt angle of the slope can be adapted to and the angle can be locked after operation, thereby ensuring that the positioning mechanism 6 always remains parallel and in contact with the template surface, preventing positioning deviation during the installation of the assembled template; The drive mechanism 5 is used to control the positioning of the entire device on the slope. The drive mechanism 5 is located in the inner cavity of the connecting box 2. By setting the drive mechanism 5, a linear thrust can be generated to push the internal components to move smoothly, thereby triggering the clamping action of the positioning mechanism 6 and simultaneously controlling the locking state of the angle limiting mechanism 4. Positioning mechanism 6 is used to position the connection point of two prefabricated formworks during slope construction. Positioning mechanism 6 is fixed to the lower surface of connecting plate 3. By setting up positioning mechanism 6, high frictional contact is formed between the components and the formwork surface. At the same time, under the drive of drive mechanism 5, a stable clamping force is applied to the connection point of the two prefabricated formworks to prevent the formworks from misaligning or opening during concrete pouring. The drive mechanism 5 includes an internally threaded tube 54 and a sliding rod 57. The internally threaded tube 54 is slidably connected to the inner cavity of the connecting box 2, and a connecting block 56 is fixed to one end of the internally threaded tube 54 extending to the outer surface of the connecting box 2. The sliding rod 57 is slidably connected to the inner cavity of the connecting box 2, and its end is fixed to the outer surface of the connecting block 56. The internally threaded tube 54 serves as the linear motion actuator of the drive mechanism 5, its internal thread engaging with the drive end of the drive mechanism 5 to convert rotational motion into linear movement. The sliding rod 57 moves with the internally threaded tube 54, triggering the locking or unlocking of the angle limiting mechanism 4 and transmitting the driving force to the positioning mechanism 6. The connecting block 56 rigidly connects the internally threaded tube 54 and the sliding rod 57, ensuring synchronous movement of both. The positioning mechanism 6 includes a positioning plate 61, which is fixed to the lower surface of the connecting plate 3. Anti-slip strips 62 are symmetrically fixed to the sides of the lower surface of the positioning plate 61. By setting the positioning plate 61 as a clamping element that directly contacts the template, the anti-slip strips 62 on its lower surface can be embedded into the tiny bumps and depressions on the template surface to increase friction and prevent slippage.

[0023] The angle limiting mechanism 4 includes a limiting frame 41, which is fixed to the side of the upper surface of the base plate 1. A sliding frame 42 is slidably connected to the inner cavity of the limiting frame 41. The side of the upper surface of the sliding frame 42 is an upwardly curved surface. A first positioning ring 43 passes through the upper surface of the sliding frame 42. A first rotating frame 44 is rotatably connected to the inner cavity of the first positioning ring 43. The first rotating frame 44 is fixed to the lower surface of the connecting box 2. By setting the limiting frame 41 and fixing it to the upper surface of the base plate 1, it provides vertical sliding guidance for the sliding frame 42 and limits its lateral displacement. By setting the sliding frame 42, it can slide up and down along the limiting frame 41, so that the sliding frame 42 automatically adjusts its extension height according to the slope, thereby achieving angle self-adaptation. By setting the first positioning ring 43 and fixing it to the upper surface of the sliding frame 42, it supports the first rotating frame 44 and allows it to rotate. By setting a first rotating frame 44, which is fixed on the lower surface of the connecting box 2 and rotatably connected to the first positioning ring 43, the connecting box 2 can swing relative to the sliding frame 42, thereby adapting to different slope angles.

[0024] A second positioning ring 45 is fixedly mounted on the upper surface of the sliding frame 42. A second rotating frame 46 is rotatably connected to the inner cavity of the second positioning ring 45. A support column 48 is fixedly mounted at the bottom end of the second rotating frame 46, and the support column 48 is press-fitted with the lower surface of the sliding frame 42. An arc-shaped sleeve 47 is fixedly mounted at the top end of the second rotating frame 46. The upward curved surface on the side of the upper surface of the sliding frame 42 facilitates the movement of the support column 48. By setting the second positioning ring 45, which is fixed to the upper surface of the sliding frame 42 and rotatably connected to the second rotating frame 46, the second rotating frame 46 can rotate stably. At the same time, a spring is set on the outer surface of one end of the second rotating frame 46 located in the inner cavity of the second positioning ring 45, which enables the second rotating frame 46 to generate a restoring force after rotation. By setting the second rotating frame 46, the support column 48 at its bottom end contacts the lower surface of the sliding frame 42, which plays a supporting and limiting role, so that the sliding frame 42 does not contact the upper surface of the base plate 1, and the sliding frame 42 can move downward after the device is placed. By setting an arc-shaped sleeve 47, which is fixed to the top of the second rotating frame 46, it is used to receive the thrust of the extrusion frame 511. When the drive mechanism 5 is activated, the extrusion frame 511 pushes the arc-shaped sleeve 47, causing the second rotating frame 46 to rotate, thereby causing the support column 48 to disengage from the lower surface of the sliding frame 42. Since the support column 48 no longer supports the lower surface of the sliding frame 42, the sliding frame 42 descends under the action of gravity.

[0025] There are two sliding rods 57, which are symmetrically slidably connected to the inner cavity of the connecting box 2. A pressing frame 511 is fixed on the lower surface of the end of the sliding rod 57 away from the connecting block 56. The pressing frame 511 is adapted to the surface of the arc-shaped sleeve 47. By setting the pressing frame 511 and fixing it to the lower surface of the end of the sliding rod 57, when the sliding rod 57 moves to the inside of the slope, the pressing frame 511 presses against the surface of the arc-shaped sleeve 47, forcing the arc-shaped sleeve 47 and the second rotating frame 46 to rotate.

[0026] A circular hole is provided on the lower surface of the first positioning ring 43. A first spring tube 410 is fixed at the circular hole on the lower surface of the first positioning ring 43. A first locking post 411 is fixed at the bottom end of the first spring tube 410. The end of the first locking post 411 extending into the inner cavity of the first positioning ring 43 is a strip-shaped locking block. Several annularly distributed locking grooves 49 are provided on the lower surface of the first rotating frame 44. The top end of the first locking post 411 is fitted into the locking groove 49. By setting the first spring tube 410, an upward elastic thrust is provided, so that the first locking post 411 always has a tendency to insert into the locking groove 49. By setting the top end of the first locking post 411 to be a strip-shaped locking block, which cooperates with the annularly distributed locking grooves 49 on the lower surface of the first rotating frame 44, when the sliding frame 42 is in the descending state, the locking post inserts into the locking groove 49, locking the angle between the first positioning ring 43 and the first rotating frame 44, so that the positioning mechanism 6 no longer changes angle.

[0027] The drive mechanism 5 also includes a connecting frame 51, which is fixed to the upper surface of the connecting box 2. A stepper motor 52 is fixed to the inner wall of the connecting frame 51. The stepper motor 52 is located on the side of the connecting box 2 away from the connecting block 56. A lead screw 53 is mounted on the output end of the stepper motor 52 via a coupling. The lead screw 53 is threaded into the inner cavity of the internally threaded tube 54. Sliding strips 55 are symmetrically fixed on both sides of the outer surface of the internally threaded tube 54 and are slidably connected to the inner wall of the connecting box 2. By setting the connecting frame 51, the stepper motor 52 is fixed above the connecting box 2. By setting the stepper motor 52 as a power source, its output torque and speed can be precisely controlled. By setting the lead screw 53, which cooperates with the internally threaded tube 54, the rotational motion of the stepper motor 52 is converted into the linear motion of the internally threaded tube 54. By setting the sliding strips 55, which are symmetrically arranged on both sides of the internally threaded tube 54 and cooperate with the sliding grooves on the inner wall of the connecting box 2, the rotation of the internally threaded tube 54 is prevented, ensuring the smoothness of its linear motion.

[0028] A locking mechanism 58 is fixedly mounted on the upper surface of the connecting box 2. The locking mechanism 58 includes a fixing frame 583, which is fixedly mounted on the upper surface of the connecting box 2. A transfer box 584 is fixedly mounted on the upper surface of the fixing frame 583. A limit tube 585 passes through the outer surface of the transfer box 584. An intelligent control valve 586 is fixedly mounted on the inner wall of the limit tube 585. A piston rod 582 is slidably connected to the inner cavity of the limit tube 585. A connecting post 581 is fixedly mounted at one end of the piston rod 582 extending to the outer surface of the limit tube 585. The connecting post 581 is fixed on the upper surface of the internally threaded tube 54. By setting the fixing frame 583, the locking mechanism 58 is securely mounted on the connecting box 2. The transfer box 584 serves as a distribution chamber for the pressure medium. The limit tube 585 contains the intelligent control valve 586, which is used to control the flow of the pressure medium. By setting the piston rod 582 to extend and retract under the action of the pressure medium, the connecting column 581 is moved, thereby causing a change in the air pressure inside the limiting tube 585. The intelligent control valve 586 can connect the inner cavity of the limiting tube 585 with the transfer box 584 according to construction needs, thereby causing the air pressure change inside the limiting tube 585 to affect the inside of the transfer box 584.

[0029] A first piston 587 is slidably connected to the inner cavity of the transfer box 584. A support frame 588 is fixed to the top of the first piston 587, and a sliding column 589 is fixed to the end of the support frame 588. Fixed rings 5811 are fixed to both ends of a fixed frame 583. A second spring tube 5810 is fixed to the upper surface of the fixed ring 5811, and the top of the second spring tube 5810 is fixed to the lower surface of the sliding column 589. A locking strip 5812 is fixed to the bottom end of the sliding column 589. Several evenly distributed positioning grooves are formed on the upper surface of the sliding rod 57, and the locking strip 5812 is matched with the positioning grooves formed on the upper surface of the sliding rod 57. By setting the first piston 587, it moves up and down within the transfer box 584 driven by the pressure medium, causing the support frame 588 and the sliding column 589 to rise and fall synchronously. By providing a second spring tube 5810, an upward reset force is provided to the sliding column 589. When the pressure medium is released, the locking strip 5812 automatically lifts, releasing the lock on the sliding rod 57. The locking strip 5812, fixed to the bottom of the sliding column 589, engages with the positioning groove on the upper surface of the sliding rod 57. When the locking strip 5812 is inserted downwards into the positioning groove, the sliding rod 57 is locked in its current position, thus maintaining the continuous clamping force of the positioning plate 61 on the template. Multiple positioning grooves provide multiple locking positions to accommodate different template thicknesses and clamping requirements.

[0030] A sealing frame 59 is fixed to the side of the connecting block 56 away from the internally threaded tube 54. A sealing plug is provided at the end of the sealing frame 59. A fixing strip 63 penetrates the upper surface of the positioning plate 61. Several linearly distributed holes are formed on the upper surface of the fixing strip 63. A connection port 64 is fixed to the top of each hole on the upper surface of the fixing strip 63. A flat tube 65 passes through the top of the connection port 64. The inner cavity of the flat tube 65 is filled with hydraulic oil. The sealing plug at the end of the sealing frame 59 is tightly slidably connected to the inner wall of the flat tube 65. By setting the sealing frame 59, the sealing plug at its end slides tightly against the inner wall of the flat tube 65, forming a piston structure. When the internally threaded tube 54 moves, the sealing frame 59 moves within the flat tube 65, pressing hydraulic oil into or out of the connection port 64. The fixing strip 63 is fixed to the positioning plate 61, and its internal holes communicate with the connection port 64, serving as a pressure transmission channel. By setting a flat tube 65 as a sliding cylinder for sealing plugs, and guiding the pressure medium to each connection port 64, the synchronous operation of multiple extrusion heads 68 is achieved.

[0031] A return spring 66 is installed at the hole in the fixing strip 63. The top of the return spring 66 is fixed to the lower surface of the connection port 64, and a second piston 67 is fixed to the bottom of the return spring 66. The second piston 67 rubs tightly against the hole in the fixing strip 63, and a pressing head 68 is fixed to the lower surface of the second piston 67. By setting the return spring 66, the second piston 67 is pushed upward under normal conditions, causing the pressing head 68 to retract into the fixing strip 63. By setting the second piston 67, under the action of the pressure medium, it overcomes the return spring 66 and moves downward, pushing the pressing head 68 out. By setting the pressing head 68, after it extends, it is slightly lower than the lower surface of the positioning plate 61, directly pressing the template surface. When the pressure medium is removed, the return spring 66 causes the pressing head 68 to automatically retract, facilitating the disassembly of the device. Multiple pressing heads 68 are evenly distributed on the positioning plate 61 to ensure uniform pressing force and avoid local deformation of the template. Working principle: When using, first place the entire device on the slope near the pre-positioned assembly template connection. The base plate 1 is in direct contact with the slope, serving as the load-bearing foundation for the entire device. At this time, the angle limiting mechanism 4 begins adaptive adjustment. The first rotating frame 44, fixed to the lower surface of the connecting box 2, rotates relative to the first positioning ring 43, causing the connecting box 2 and the connecting plate 3 to swing until the lower surface of the positioning plate 61 is completely parallel and in contact with the template surface. During this process, the support column 48 at the bottom of the second rotating frame 46 supports the lower surface of the sliding frame 42, preventing the sliding frame 42 from falling due to its own weight.

[0032] Start the stepper motor 52. The stepper motor 52 drives the internally threaded tube 54 to move linearly towards the inside of the slope via the lead screw 53. The sliding strip 55 on the outer surface of the internally threaded tube 54 cooperates with the sliding groove on the inner wall of the connecting box 2 to ensure smooth movement. The internally threaded tube 54 drives the connecting block 56 and the two sliding rods 57 to move forward synchronously. The pressing frame 511 on the lower surface of the end of the sliding rod 57 moves forward accordingly, pressing against the arc-shaped sleeve 47 at the top of the second rotating frame 46, forcing the second rotating frame 46 to overcome the elastic force of the spring at its pivot and rotate. The support column 48 at the bottom of the second rotating frame 46 disengages from the lower surface of the sliding frame 42 as it rotates. After losing support, the sliding frame 42 slides downward along the limiting frame 41 under its own weight. As the sliding frame 42 moves downward, the first positioning ring 43 drives the sliding frame 42 to move downward relative to the first locking post 411, so that the top of the first locking post 411 is matched with the locking groove 49, thereby completing the locking operation.

[0033] As the sliding rod 57 moves forward, the sealing plug at the end of the sealing bracket 59, fixed on the connecting block 56, slides synchronously within the flat tube 65. The inner cavity of the flat tube 65 is pre-filled with hydraulic oil. When the sealing plug moves forward, it presses the hydraulic oil into the holes inside each connecting port 64 and the fixing strip 63. The pressure of the hydraulic oil pushes the second piston 67 downward against the elastic force of the return spring 66, causing the extrusion head 68 to extend from the lower surface of the fixing strip 63. The extrusion head 68, together with the anti-slip strip 62 on the lower surface of the positioning plate 61, presses the joint of the assembled template tightly. Because multiple extrusion heads 68 are evenly distributed on the positioning plate 61, the pressing force is evenly applied to the template surface, avoiding localized deformation or indentations.

[0034] When the sliding rod 57 moves to the preset position and the extrusion head 68 fully presses against the template, the locking mechanism 58 activates. The intelligent control valve 586 opens, and the pressure medium enters the transfer box 584 through the limit tube 585, pushing the first piston 587 downward. The first piston 587 drives the sliding column 589 to descend via the support frame 588, compressing the second spring tube 5810.
