Description

Technical Field

[0001] This utility model relates to the field of water conservancy pipeline technology, specifically a height-adjustable water conservancy pipeline support frame. Background Technology

[0002] Water conservancy pipelines, as the core carriers of modern water resource transportation, are constructed from materials such as polyethylene, cast iron, and concrete. They are assembled using processes such as socket joints and flange connections. Their design must take into account pressure resistance, leak-proof performance, and corrosion resistance. Common types include water supply pipes, drainage pipes, and irrigation pipes. They are widely used in municipal engineering, agricultural irrigation, and industrial circulating water systems. They achieve efficient water transmission through pressure flow or gravity flow, meeting the flow regulation and distribution needs in different scenarios. Existing water conservancy pipelines are generally installed and supported by water conservancy pipeline supports. As an important support structure, water conservancy pipeline supports are generally made of steel, concrete, or composite materials, and ensure the stable load-bearing capacity of the pipeline through methods such as fixed clamps and sliding supports.

[0003] However, it still has some drawbacks, such as the need for tools and cumbersome operation when adjusting the height of the water conservancy pipeline support frame, and the possibility of it falling due to gravity during the lowering process and use, which poses a safety hazard and affects the stability of the pipeline.

[0004] To address the aforementioned problems, this application proposes a height-adjustable hydraulic pipeline support frame. Utility Model Content

[0005] The purpose of this utility model is to provide a height-adjustable hydraulic pipeline support frame to solve the problems mentioned in the background art, such as the need for tools and cumbersome operation when adjusting the height of the hydraulic pipeline support frame, and the possibility of it falling due to gravity during the lowering process and use.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a height-adjustable hydraulic pipeline support frame, including a support frame base, a rotation limiting groove is provided on the upper part of the support frame base, a turntable limiting strip is movable inside the rotation limiting groove, the turntable limiting strip is fixedly connected to the lower part of the anti-fall height adjustment plate, an anti-reverse sliding plate is installed on the front of the support frame base, and the anti-fall height adjustment plate facilitates the raising of the pipeline support bracket by turning the turntable, making the operation simpler and requiring no tool intervention. Furthermore, the anti-fall height adjustment plate has a lowering locking structure. When raising, the inclined limiting block can be directly squeezed to allow unobstructed raising operation. When lowering, the rectangular surface of the limiting block will lock the anti-fall height adjustment plate, requiring unlocking before lowering, thus preventing rapid falls or sudden falls during use and improving safety.

[0007] Preferably, a fixed base plate is fixedly connected below the support frame base, a lifting auxiliary cylinder is movable above the support frame base, a pipe support bracket is fixedly connected above the lifting auxiliary cylinder, and a lifting engagement threaded groove is opened inside the anti-fall height adjustment disc.

[0008] Preferably, an anti-slip layer is fixedly connected to the outer surface of the anti-fall height adjustment disc, a long threaded lifting rod is fixedly connected to the lower part of the lifting auxiliary cylinder, rectangular rotation limit plates are fixedly connected to both sides below the long threaded lifting rod, and the outer surface of the long threaded lifting rod is engaged with the lifting engagement thread groove.

[0009] Preferably, an L-shaped bracket is installed on one side of the anti-reverse sliding plate. The L-shaped bracket is located inside the support frame base. An inclined rectangular block is fixedly connected above the L-shaped bracket. The inclined rectangular block is movable above the support frame base.

[0010] Preferably, a thrust damping spring is fixedly connected below the L-shaped bracket. The thrust damping spring is located inside the support frame base. The inclined rectangular block is detachable inside the lifting and fixing slot. The lifting and fixing slot is located below the anti-fall height adjustment disc and is distributed in a ring. Multiple sets of lifting and fixing slots are provided.

[0011] Preferably, the support frame base has a telescopic rod lifting groove on its upper part and inside, and a long threaded lifting rod is movable inside the telescopic rod lifting groove. Anti-rotation limiting grooves are provided on both sides of the telescopic rod lifting groove, and a rectangular rotation limiting plate is movable inside the anti-rotation limiting groove. When using this device, the anti-fall height adjustment disc forms a threaded engagement transmission with the long threaded lifting rod through the lifting engagement threaded groove. When the anti-fall height adjustment disc is rotated counterclockwise, the disc limiting strip slides along the rotation limiting groove, and the lifting engagement threaded groove engages with the long threaded lifting rod, driving the long threaded lifting rod to extend... The lifting rod rises within the retractable lifting slot. At this point, the inclined rectangular block's slope is compressed by the anti-fall height adjustment disc at the bottom, creating a damping spring that allows the lifting station to smoothly pass through the inclined rectangular block and complete the height increase. When rotating clockwise, the rectangular surface of the inclined rectangular block engages with the lifting station, forming a mechanical self-lock. The anti-reverse sliding plate must be pressed first to disengage the inclined rectangular block from the lifting station before lowering can begin. The cooperation between the rectangular rotation limit plate and the anti-rotation limit slot prevents the long threaded lifting rod from rotating, ensuring stable vertical lifting of the lifting auxiliary cylinder and the pipe support bracket.

[0013] This invention features a fall-prevention height adjustment disc, which facilitates the raising of pipe support brackets via a turntable, making operation simpler and requiring no tool intervention. The fall-prevention height adjustment disc also incorporates a lowering locking structure. When raising the height, the inclined limiting block can be directly pressed, allowing for unobstructed lifting. When lowering the height, the rectangular surface of the limiting block will lock the fall-prevention height adjustment disc, requiring unlocking before lowering. This prevents rapid or sudden falls during use, thus enhancing safety. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] In this embodiment, as shown Figures 1-2As shown, a fixed base plate 11 is fixedly connected to the bottom of the support frame base 1, a lifting auxiliary cylinder 2 is movable above the support frame base 1, a pipe support bracket 3 is fixedly connected above the lifting auxiliary cylinder 2, a lifting engagement threaded groove 42 is opened inside the anti-fall height adjustment plate 4, an anti-slip layer 41 is fixedly connected to the outer surface of the anti-fall height adjustment plate 4, a long threaded lifting rod 21 is fixedly connected to the bottom of the lifting auxiliary cylinder 2, rectangular rotation limit plates 22 are fixedly connected to both sides below the long threaded lifting rod 21, and the outer surface of the long threaded lifting rod 21 is engaged with the lifting engagement threaded groove 42.

[0021] In this embodiment, as shown Figures 3-4 As shown, an L-shaped bracket 51 is installed on one side of the anti-reverse sliding plate 5. The L-shaped bracket 51 is located inside the support frame base 1. An inclined rectangular block 52 is fixedly connected above the L-shaped bracket 51. The inclined rectangular block 52 moves above the support frame base 1. A thrust damping spring 53 is fixedly connected below the L-shaped bracket 51. The thrust damping spring 53 consists of a spring and a damping rod and is used to provide a limiting thrust. The thrust damping spring 53 is located inside the support frame base 1. The inclined rectangular block 52 is detachable inside the lifting and fixing groove 44. The lifting and fixing groove 44 is located below the anti-fall height adjustment plate 4 and is arranged in a ring. Multiple sets of lifting and fixing grooves 44 are provided. A telescopic rod lifting groove 13 is provided above and inside the support frame base 1. A long threaded lifting rod 21 moves inside the telescopic rod lifting groove 13. Anti-rotation limiting grooves 14 are provided on both sides of the telescopic rod lifting groove 13. A rectangular rotation limiting plate 22 moves inside the anti-rotation limiting groove 14. When using this device, the anti-rotation limiting plate 22 moves inside the anti-rotation limiting groove 14. The fall height adjustment disc 4 forms a threaded engagement transmission with the long threaded lifting rod 21 through the lifting engagement threaded groove 42. When the fall height adjustment disc 4 is rotated counterclockwise, the turntable limit bar 43 slides along the rotation limit groove 12, and the lifting engagement threaded groove 42 engages with the long threaded lifting rod 21, causing the long threaded lifting rod 21 to rise in the telescopic rod lifting groove 13. At this time, the inclined surface of the inclined rectangular block 52 is squeezed and compressed by the bottom of the fall height adjustment disc 4, which compresses the thrust damping spring 53, allowing the lifting fixing groove 44 to smoothly pass through the inclined rectangular block 52 to complete the height increase. When rotated clockwise, the rectangular surface of the inclined rectangular block 52 will be locked into the lifting fixing groove 44 to form a mechanical self-lock. The anti-reverse sliding plate 5 must be pressed first to disengage the inclined rectangular block 52 from the lifting fixing groove 44 before the descent operation can be realized. The cooperation between the rectangular rotation limit plate 22 and the anti-rotation limit groove 14 can prevent the long threaded lifting rod 21 from rotating, ensuring that the lifting auxiliary cylinder 2 drives the pipe support bracket 3 to achieve stable vertical lifting.

[0022] Please see Figures 1-4A height-adjustable hydraulic pipeline support frame includes a support frame base 1, a rotation limiting groove 12 on the top of the support frame base 1, a turntable limiting strip 43 inside the rotation limiting groove 12, and the turntable limiting strip 43 fixedly connected to the bottom of the anti-fall height adjustment plate 4. An anti-reverse sliding plate 5 is installed on the front of the support frame base 1. The anti-fall height adjustment plate 4 facilitates raising the pipeline support bracket 3 by turning the plate, making operation simpler and requiring no tool intervention. The anti-fall height adjustment plate 4 is equipped with a lowering locking structure. When raising, the inclined limiting block can be directly squeezed to allow the raising operation to proceed smoothly. When lowering, the rectangular surface of the limiting block will lock the anti-fall height adjustment plate 4, requiring unlocking before lowering, thus preventing rapid falls or sudden falls during use and improving safety.

[0023] Working principle

[0024] A height-adjustable anti-fall height adjustment disc 4 for a hydraulic pipeline support frame facilitates raising the pipeline support bracket 3 via a turntable, simplifying operation and eliminating the need for tools. The anti-fall height adjustment disc 4 features a lowering locking structure. When raising, the inclined limit block can be directly pressed, allowing for unobstructed lifting. When lowering, the rectangular surface of the limit block will lock the anti-fall height adjustment disc 4, requiring unlocking before lowering, thus preventing rapid or sudden falls and improving safety. In use, the anti-fall height adjustment disc 4 engages with the long threaded lifting rod 21 via a lifting engagement threaded groove 42. When the anti-fall height adjustment disc 4 is rotated counterclockwise, the turntable limit bar 43 moves along the rotation limit... Sliding groove 12 causes the lifting engagement thread groove 42 to engage with the long thread lifting rod 21, driving the long thread lifting rod 21 to rise within the telescopic rod lifting groove 13. At this time, the inclined surface of the inclined rectangular block 52 is compressed by the bottom of the anti-fall height adjustment disc 4, which compresses the thrust damping spring 53, allowing the lifting fixing groove 44 to smoothly pass through the inclined rectangular block 52 to complete the height increase. When rotating clockwise, the rectangular surface of the inclined rectangular block 52 will be locked into the lifting fixing groove 44 to form a mechanical self-lock. The anti-reverse sliding plate 5 must be pressed first to disengage the inclined rectangular block 52 from the lifting fixing groove 44 before the descent operation can be achieved. The cooperation between the rectangular rotation limit plate 22 and the anti-rotation limit groove 14 can prevent the long thread lifting rod 21 from rotating, ensuring that the lifting auxiliary cylinder 2 drives the pipe support bracket 3 to achieve stable vertical lifting.
