Description

Technical Field

[0001] This invention relates to the field of construction equipment technology, and in particular to a support frame device. Background Technology

[0002] Prestressed corrugated pipes for LNG storage tanks are core embedded components in the post-tensioned prestressed system of the concrete outer tank of a full-containment cryogenic storage tank. They are mainly used to provide a channel and protective sleeve for the circumferential and vertical prestressed steel strands, and to form a grouting cavity after tensioning to ensure that the prestress is effectively transferred to the concrete structure. In the production of prestressed corrugated pipes for LNG storage tanks, disc steel strips are the core raw material, and their stability directly affects the forming quality and processing efficiency of the corrugated pipes.

[0003] Traditional methods for producing prestressed corrugated pipes for LNG storage tanks rely on manual operation or simple fixtures. Both manual operation and simple tools can introduce significant errors, especially in the manufacture of corrugated pipes for large storage tanks, where these errors are amplified, ultimately leading to large dimensional deviations in the corrugated pipes and low production efficiency. Summary of the Invention

[0023] This invention provides a support frame device 100. Figures 1 to 3 This is an embodiment of the support frame device 100 provided by the present invention.

[0024] In the existing traditional production of prestressed corrugated pipes for LNG storage tanks, the disc steel strip is the core raw material, and its positioning stability has a decisive impact on the forming quality of the corrugated pipe. Traditional methods rely on manual operation or simple clamps, which leads to positional deviations of the disc steel strip during processing. This deviation is amplified, especially in the manufacturing of corrugated pipes for large storage tanks, causing the corrugated pipe dimensions to fail to meet design requirements, thus affecting the effective transfer of prestress. This problem stems from the fact that manual operation cannot achieve precise radial and circumferential positioning of the disc steel strip, introducing geometric errors into the corrugated pipe forming stage, ultimately resulting in discontinuities in the prestressed steel strand threading channels.

[0025] Please refer to the following: Figures 1 to 3 The support frame device 100 includes a base 1, a rotating shaft 2, and a fixing structure 3. The rotating shaft 2 is rotatably mounted on the top of the base 1, and the axis of the rotating shaft 2 extends in the front-rear direction. The fixing structure 3 includes a baffle 31, an adjusting component 33, and a plurality of arc-shaped support members 32. The baffle 31 is mounted on the rotating shaft 2, and the plurality of arc-shaped support members 32 are slidably mounted on the baffle 31. Each arc-shaped support member 32 moves radially along the rotating shaft 2 and is spaced apart circumferentially along the rotating shaft 2. The adjusting component 33 includes an adjusting cylinder 3a and a plurality of support rods 3b. The adjusting cylinder 3a is threadedly connected to the rotating shaft 2 and slides axially along the rotating shaft 2. The two ends of each support rod 3b are respectively hinged to the arc-shaped support member 32 and the adjusting cylinder 3a.

[0026] The baffle 31 can be a disc-shaped or polygonal plate. The arc-shaped support 32 can be designed as a plate-shaped structure with a certain curvature, the inner curvature of which matches the shape of the disc steel strip. The sliding connection between the arc-shaped support 32 and the baffle 31 can be achieved by a guide rail and a slider mechanism. For example, a radial groove can be provided on the baffle 31, and a slider that cooperates with the groove can be provided at the bottom of the arc-shaped support 32, or it can be achieved by a simple pin and long hole. Each arc-shaped support 32 moves radially along the rotation axis 2 and is spaced circumferentially along the rotation axis 2, so that the arc-shaped support 32 can expand or contract radially according to the diameter of the disc steel strip, thereby adapting to steel strips of different sizes. The circumferential spacing ensures uniform support for the steel strip and avoids local stress concentration.

[0027] By rotating the adjusting cylinder 3a, it can move axially along the rotating shaft 2. The axial sliding of the adjusting cylinder 3a can be achieved by direct manual rotation or by using tools such as a handwheel or wrench. The hinged connection allows the support rod 3b to swing freely when the adjusting cylinder 3a moves axially, thus converting the axial displacement of the adjusting cylinder 3a into the radial displacement of the arc-shaped support member 32. One end of the support rod 3b is connected to the back of the arc-shaped support member 32 via a pin, and the other end is connected to the outer periphery of the adjusting cylinder 3a via a pin. When the adjusting cylinder 3a moves axially along the rotating shaft 2, the tilt angle of the support rod 3b changes, thereby pushing or pulling the arc-shaped support member 32 radially.

[0028] Therefore, in the technical solution provided by the present invention, the fixed structure 3 includes a baffle 31, an adjustment component 33, and multiple arc-shaped support members 32. The baffle 31 is installed on the rotating shaft 2, and the multiple arc-shaped support members 32 are slidably installed on the baffle 31. Each arc-shaped support member 32 moves radially along the rotating shaft 2 and is spaced apart circumferentially along the rotating shaft 2. The adjustment component 33 includes an adjustment cylinder 3a and multiple support rods 3b. The adjustment cylinder 3a is threadedly connected to the rotating shaft 2 and slides axially along the rotating shaft 2. The two ends of each support rod 3b are respectively hinged to the arc-shaped support member 32 and the adjustment cylinder 3a, so that the device can quickly and accurately adapt to disc steel strips of different diameters without replacing parts, significantly improving the convenience of operation and the accuracy of adjustment. The operator can complete the clamping and centering of the steel strip by simply rotating the adjustment cylinder 3a, avoiding the errors that may be introduced by traditional manual positioning.

[0029] There may be insufficient friction or excessively hard contact surfaces between the disc steel strip and the arc-shaped support 32, which may cause the disc steel strip to slide or shift on the support frame device 100, or even damage the surface of the disc steel strip. In order to avoid damage to the surface of the disc steel strip, which may affect its quality and subsequent use, the following measures should be taken.

[0030] In an embodiment of the present invention, an anti-slip pad is provided on the side of the arc-shaped support member 32 away from the support rod 3b.

[0031] An anti-slip mat is a material layer with a high coefficient of friction and / or cushioning performance. Its main function is to increase the friction of the contact surface, prevent objects from sliding, and provide a certain degree of cushioning protection. Anti-slip mats can be made of various materials, such as elastic materials like rubber, silicone, and polyurethane, which typically have good wear resistance and anti-slip properties. Furthermore, anti-slip mats can also be made of materials with specially treated surfaces, such as through embossing, texturing, or coating with a high-friction coating to enhance their anti-slip effect. The installation methods for anti-slip mats are diverse; for example, they can be fixed to the surface of the curved support member 32 by means of adhesive bonding, riveting, snap-fitting, or integral molding.

[0032] After the position adjustment is completed, the rotating shaft 2 may rotate unexpectedly due to external vibration or improper operation, causing the position of the supporting disc steel belt to be unstable. In order to ensure the accuracy and safety of operation, in the embodiment of the present invention, the adjusting cylinder 3a is threaded with a fixing screw, which abuts against the rotating shaft 2 to limit the rotation of the rotating shaft 2.

[0033] The fixing screw is a common fastener that is connected to the adjusting sleeve 3a by threads, allowing the operator to control its extension length by tightening or loosening the fixing screw. When the fixing screw is tightened, its end directly contacts and presses against the outer surface of the rotating shaft 2, generating sufficient friction or forming mechanical resistance. It converts the axial thrust of the fixing screw into a radial clamping force on the rotating shaft 2, which can effectively limit the rotation of the rotating shaft 2 around its axis, thereby locking it in the preset adjustment position and preventing it from rotating accidentally during operation.

[0034] Furthermore, an extension plate is provided on the outer periphery of the baffle 31 to support disc steel strips of different sizes.

[0035] The extension plate can be a ring-shaped plate, segmented slats, or a telescopic structure. For example, the extension plate can be designed to be integrally formed with the baffle 31, or fixed to the outer periphery of the baffle 31 by welding, bolting, or other methods. Alternatively, the extension plate can be designed as a detachable or adjustable modular structure to be replaced or adjusted as needed to accommodate disc steel strips of different sizes. Supporting disc steel strips of different sizes means that the device can stably bear loads from disc steel strips of various diameters. This is typically achieved by providing a larger support area or more flexible support boundaries. For example, the width or length of the extension plate can be designed to cover a wide range of common disc steel strip diameters, or it can be adapted through its own adjustability.

[0036] Ensuring that the rotating shaft 2 does not rotate accidentally is also part of the present invention. Specifically, in an embodiment of the present invention, a stop brake 5 is installed on the rotating shaft 2.

[0037] A stop brake 5 is a device used to prevent or restrict the movement of mechanical parts. The stop brake 5 can be implemented in various forms. For example, it can be a friction brake, which prevents the rotation of the rotating shaft 2 through friction, such as a holding brake or disc brake. It can also be a mechanical locking brake, which engages with the rotating shaft 2 through a mechanical structure, such as a pin-type or gear-type braking mechanism. When it is necessary to fix the rotational position of the rotating shaft 2, the stop brake 5 is activated, acting on the stop plate to prevent the free rotation of the rotating shaft 2. This design allows the rotating shaft 2 to maintain a stable position when bearing heavy loads or making fine adjustments, avoiding instability or operational errors caused by accidental rotation.

[0038] Even with only radial support from the arc-shaped support member 32, the disc steel strip may still shift downwards due to gravity, and there is even a risk of it slipping off the support frame. This could not only damage the equipment but also pose a safety hazard. In an embodiment of the present invention, a support structure 4 is provided on the base 1. The support structure 4 includes a support bracket 41, which is mounted on the base 1 to limit the downward fall of the disc steel strip mounted on the arc-shaped support member 32.

[0039] The support bracket 41 is the main part of the support structure 4. Its specific form can vary, such as an L-shaped bracket, a U-shaped frame, or a frame composed of multiple columns and beams. It is typically made of high-strength materials to bear the weight of the disc steel belt. When the disc steel belt is placed on the arc-shaped support 32, the top surface of the support bracket 41 or specific components thereon will be positioned below the disc steel belt, thus providing a reaction force when the disc steel belt attempts to move downwards, effectively preventing it from falling. This restraining effect ensures the stable placement of the disc steel belt on the support frame, maintaining its position even during rotation or adjustment.

[0040] The support structure 4 also includes a threaded rod 46, a support plate 45, multiple elastic elements 44, and a movable plate 43. The threaded rod 46 is threadedly connected to the support bracket 41 and extends in the vertical direction. The support plate 45 is disposed at the top of the threaded rod 46. Multiple elastic elements 44 are disposed on the side of the support plate 45 away from the support bracket 41. The movable plate 43 is disposed on the multiple elastic elements 44.

[0041] The threaded rod 46 is threadedly connected to the support bracket 41 and extends vertically. By rotating the threaded rod 46, the overall height of the support plate 45 and its upper components can be adjusted. The support plate 45 is located at the top of the threaded rod 46, serving as a load-bearing platform. Multiple elastic elements 44 are located on the side of the support plate 45 facing away from the support bracket 41, providing flexible support for the movable plate 43. The movable plate 43 is directly mounted on these elastic elements 44 and contacts the disc steel strip. When the disc steel strip is placed on the movable plate 43, the elastic elements 44 absorb some of the impact force and provide uniform elastic support according to the weight and shape of the disc steel strip. By adjusting the threaded rod 46, the initial height of the movable plate 43 can be precisely adjusted so that it works in conjunction with the arc-shaped support element 32 to ensure that the disc steel strip obtains the optimal support position and stability. This structure allows the support system to not only limit the sag of the disc steel strip but also provide cushioning and height fine-tuning functions, thereby effectively addressing the issues of disc steel strip size differences and placement impacts, ensuring the smooth placement and safe operation of the disc steel strip.

[0042] Furthermore, the movable plate 43 is provided with a plurality of rollers 42, each roller 42 being located on the left and right sides of the axis of the rotating shaft 2 and arranged symmetrically.

[0043] The main function of the rollers 42 is to reduce the sliding friction between the disc steel belt and the movable plate 43, converting sliding friction into rolling friction, thereby facilitating the movement, positioning, or rotation of the disc steel belt on the movable plate 43. The rollers 42 can be made of various materials, such as wear-resistant metals like steel, or polymers with certain elasticity and wear resistance, such as polyurethane or nylon. For example, the rollers 42 can be arranged in two rows, with each row located on one side of the axis of rotation 2, or they can be arranged in a ring or semi-ring shape, but their overall distribution area is still concentrated on the left and right sides of the axis of rotation 2. The symmetrical arrangement ensures that the disc steel belt receives uniform and stable support when placed or moved, preventing tilting, swaying, or damage due to uneven force. For example, the same number and specifications of rollers 42 can be set on each side of the axis of rotation 2, maintaining a consistent radial distance from the axis of rotation 2.

[0044] Furthermore, the outer periphery of the roller 42 is provided with an anti-slip sleeve.

[0045] Anti-slip sleeves can be made of a variety of materials. For example, they can be made of rubber materials with a high coefficient of friction, such as nitrile rubber, EPDM rubber, or polyurethane rubber. These materials have good wear resistance and elasticity, providing stable grip. In addition, anti-slip sleeves can also be made of materials with special surface textures or coatings, such as by molding raised, grooved, or grid-like textures onto the sleeve surface to further enhance their anti-slip performance.

[0046] In the technical solution of the present invention, a limiting rod is provided on the side of the support plate 45 facing the support bracket 41, and the limiting rod is movably connected to the support bracket 41.

[0047] When the support plate 45 is adjusted up and down via the threaded rod 46, the limiting rod, constrained by the support bracket 41, guides the support plate 45 to move smoothly along a preset vertical direction, effectively preventing lateral swaying or deviation of the support plate 45 during adjustment. Simultaneously, when the disc steel strip is placed on the movable plate 43 and the load is transferred to the support plate 45 via the elastic element 44, the movable connection between the limiting rod and the support bracket 41 restricts the lateral displacement and tilt of the support plate 45, ensuring that the support plate 45 always remains within the effective support range of the support bracket 41, thereby providing stable and reliable support for the disc steel strip.

[0048] At least two limiting rods may be provided on the side of the support plate 45 facing the support bracket 41. These limiting rods are cylindrical and perpendicular to the plane of the support plate 45. Corresponding guide holes are provided on the support bracket 41 to mate with the limiting rods. Each limiting rod passes through a guide hole, thereby achieving a movable connection between the limiting rod and the support bracket 41. The inner diameter of the guide hole is slightly larger than the outer diameter of the limiting rod to allow the limiting rod to slide smoothly up and down within the guide hole, while restricting its lateral and vertical degrees of freedom.

[0049] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention specification and drawings under the concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
