Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a temporary fixed support device and method for large pipelines. Background Technology

[0002] In new and expanded municipal engineering projects, construction sites often involve the dismantling and alteration of existing pipelines. During this process, the temporary support of large pipelines is typically required. For some process pipelines, the height of the supported pipeline above the ground also needs to be considered. Workers generally employ several traditional support methods:

[0003] 1. Set up concrete pads and blocks, and erect steel pipe scaffolding;

[0004] 2. Set up unused sleepers and blocks;

[0005] 3. Use local materials, such as discarded bricks and mortar, to build a temporary support.

[0006] These three traditional methods have many drawbacks: purchasing concrete blocks increases construction costs; building temporary supports and preparing mortar generate dust pollution, and workers also face occupational health risks of pneumoconiosis, and the need for curing after construction increases the construction period; while setting up support frames, laying multiple layers of concrete blocks, laying multiple layers of sleepers, and building temporary supports are all time-consuming; and there may be some uncertain safety hazards in the installation and dismantling of large pipeline support frames.

[0007] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0008] To overcome the shortcomings of existing technologies, a temporary fixed support device and a temporary support method for large pipelines are provided to solve the problems of long construction time and safety hazards during installation and dismantling of existing temporary pipeline support methods.

[0009] To achieve the above objectives, a temporary fixed support device for large pipelines is provided, comprising:

[0010] Two substrates are arranged opposite each other. The bottom of each substrate has multiple receiving holes. Anchoring components for embedding in the foundation are installed in the receiving holes in a way that allows them to be raised and lowered. Two guide rails arranged in the same direction are installed on the top of each substrate. The guide rails form grooves. The grooves on the guide rails of the two substrates are collinear. The opposite side walls of the grooves have through holes arranged along the length of the groove. Multiple limiting components are fixed on the outer side of the side walls at intervals along the length of the groove.

[0011] The translation frame has two sliding plates connected to its lower part. The sliding plates slide in the groove. The opposite sides of the sliding plates are movably inserted through the perforation and extend to the outside of the side wall. The opposite sides of the sliding plates are provided with height-adjustable anti-reverse members, which are disposed between two adjacent limiting members.

[0012] A lifting frame is mounted on the translation frame in a lifting manner, and an arc-shaped support plate for supporting large pipes is detachably connected between the lifting frames on the two base plates.

[0013] A locking beam is formed in the upper part of the lifting frame, and the locking beam is adjusted to pass through the through hole. A tie member is detachably connected between one end of the locking beam on the two base plates.

[0014] Furthermore, the translation frame includes two legs and a lower connecting beam connected between the upper ends of the two legs, and the sliding plate is connected to the lower end of the legs.

[0015] Furthermore, the support leg has a vertically arranged socket hole inside, the lifting frame includes two columns, the columns are movably inserted into the socket hole, the side wall of the column is equipped with a rack, and the upper part of the support leg is rotatably equipped with a drive gear, the drive gear meshing with the rack.

[0016] Furthermore, a central connecting beam connects the two columns, and both ends of the support plate are detachably connected to the central connecting beam of the lifting frame of the two base plates.

[0017] Furthermore, the anti-reverse component includes:

[0018] A side plate is vertically mounted on the side of the slide plate, and a recessed groove is formed at the top of the side plate;

[0019] A core board, the lower part of which is movably inserted into the recessed groove;

[0020] Fasteners for locking the core plate are installed on the side plate.

[0021] Furthermore, the upper part of the core plate is provided with a through hole along the length direction of the slide groove. Two locking rods are movably accommodated in the through hole, and an elastic element is connected between the two locking rods. A pusher is installed in the through hole to support the two locking rods so that one end of each locking rod extends to the outside of both ends of the through hole. After the pusher pushes the two locking rods, the opposite ends of the two locking rods abut against the upper part of the two adjacent limiting elements.

[0022] Furthermore, the end faces of the opposite ends of the locking rods are formed with guide slopes, and the upper part of the core plate is provided with an inlet hole communicating with the through hole. The guide slopes of the two locking rods each have a near end and a far end. The near ends of the two locking rods are arranged opposite each other, and the far ends of the two locking rods are arranged opposite each other. The pusher is movably inserted into the inlet hole and supported between the far ends of the two locking rods. After pressing the pusher towards the near end, the pusher slides along the inclined direction of the guide slope and is supported on the near ends of the two locking rods so that one end of the two locking rods extends to the outside of both ends of the through hole.

[0024] The two base plates are respectively placed on opposite sides of the foundation below the large pipe;

[0025] Lower the anchors of the two substrates so that the anchors are embedded in the foundation;

[0026] Based on the outer diameter of the large pipe, the first distance between the translation frames on the two substrates is adjusted so that the first distance is adapted to the outer diameter of the large pipe.

[0027] After the translation frame is adjusted to the desired position, the height of the anti-reverse component is adjusted so that the upper part of the anti-reverse component is positioned between two adjacent limiting components.

[0028] Adjust the height of the support plate of the lifting frame based on the elevation of the bottom of the large pipeline;

[0029] The large pipe is hoisted and placed on the support plate;

[0030] Adjust the position of the locking beams on the two substrates so that the two locking beams are close to each other;

[0044] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0045] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0046] Reference Figures 1 to 10 As shown, the present invention provides a temporary fixed support device for large pipelines, including: a base plate 1, a translation frame 2, a lifting frame 3, and a locking beam 4.

[0047] The system comprises two substrates. The two substrates 1 are arranged opposite each other, with each substrate having a facing end and a back-to-back end. The facing ends of the two substrates are arranged opposite each other, while the back-to-back ends of the two substrates are far apart from each other.

[0048] See Figure 10 As shown, the bottom of the substrate 1 has multiple receiving holes. Anchoring members 11 are installed in the receiving holes at the bottom of the substrate 1 in a way that allows them to be raised and lowered. The anchoring members 11 are used to be embedded in the foundation to lock the substrate onto the foundation.

[0049] In this embodiment, a push cylinder is installed at the bottom of the receiving hole. The push cylinder has a fixed end and a telescopic end. The fixed end of the push cylinder is connected to the bottom of the receiving hole. The telescopic end of the push cylinder is connected to the anchoring member.

[0050] In a preferred embodiment, the anchor is conical in shape. The telescopic end of the jacking cylinder is connected to the large end of the anchor, so that the small end of the anchor is aligned with the foundation.

[0051] After the substrate is laid on the foundation, the jacking cylinder extends, causing the anchor to penetrate into the foundation, thereby locking the substrate onto the foundation.

[0052] See Figure 1 As shown, two guide rails arranged in the same direction are mounted on the top of the substrate 1. The guide rails are formed with grooves. The grooves on the guide rails of the two substrates 1 are collinear. The opposite side walls of the grooves are formed with through holes arranged along the length direction of the groove. A plurality of limiting members 121 are fixed on the outer side of the side walls and spaced apart along the length direction of the groove.

[0053] In this embodiment, the guide rails are arranged along the length direction of the substrate. The two guide rails are arranged along the width direction of the substrate.

[0054] The lower part of the translation frame 2 is connected to two sliding plates 21. The sliding plates 21 are slidably disposed in the sliding groove. The opposite sides of the sliding plates 21 are movably inserted through the perforations and extend to the outer side of the sidewall. The opposite sides of the sliding plates 21 are provided with height-adjustable anti-reverse members 22. The anti-reverse members 22 are disposed between two adjacent limiting members 121.

[0055] Continue reading Figure 1 As shown, the translation frame 2 can move along the length of the substrate via two sliding plates at its bottom, thereby adjusting the distance between the translation frames 2 on the two substrates.

[0056] In this embodiment, the anti-reverse component 22 includes: a side plate, a core plate, and fasteners.

[0057] Specifically, the side plate is vertically mounted on the side of the slide plate 21. A recessed groove is formed at the top of the side plate.

[0058] The lower part of the core plate is movably inserted into a recessed groove. Fasteners are installed on the side plate. The fasteners are used to lock the core plate.

[0059] The side panel has a locking hole. The core panel has multiple second locking holes. The multiple second locking holes are spaced apart vertically. Fasteners are detachably inserted into the first locking hole and a second locking hole that are positioned opposite each other.

[0060] After the translation frame is in place, pull the core plate upwards so that the upper end of the core plate extends between the two adjacent limiting members. Then, insert the fasteners into the first and second locking holes that are now in the same position to fix the height of the anti-reverse member.

[0061] See Figure 4 and Figure 5 As shown, the upper part of the core plate has a through hole arranged along the length of the slide groove. Two locking rods 23 are movably accommodated in the through hole. An elastic member 41 connects the two locking rods 23. A pusher 24 is installed in the through hole to support the two locking rods 23 so that one end of each locking rod 23 extends to the outside of both ends of the through hole. After the pusher 24 pushes the two locking rods 23, the opposite ends of the two locking rods 23 abut against the upper parts of the two adjacent limiting members 121.

[0062] In this embodiment, the end faces of the opposite ends of the locking rods 23 are formed with guide slopes. An inlet hole communicating with the through hole is provided on the upper part of the core plate. The guide slopes of the two locking rods 23 each have a proximal end and a distal end. The proximal ends of the two locking rods 23 are arranged opposite each other. The distal ends of the two locking rods 23 are arranged opposite each other. A pusher 24 is movably inserted into the inlet hole and supported between the distal ends of the two locking rods 23. After pressing the pusher 24 towards the proximal end, the pusher 24 slides along the inclined direction of the guide slope and is supported on the proximal ends of the two locking rods 23, causing one end of each locking rod 23 to extend to the outside of both ends of the through hole.

[0063] See Figure 2 As shown, in this embodiment, the core plate is inserted between two adjacent limiting members. The opposite sides of the core plate are respectively spaced apart from the two adjacent limiting members. Rubber anti-collision members are embedded in the gaps to prevent the core plate from colliding with the limiting members.

[0064] Furthermore, the rubber anti-collision component includes two sleeves and a support block connected to the two rings. The two sleeves are detachably fitted onto the outside of the two adjacent limiting components.

[0065] In a preferred embodiment, an elastic reset element is connected between the pusher and the inner wall of the through hole. The elastic reset element and the elastic element are helical springs. A rotating door plate is pivotally connected to the outer opening of the inlet hole. After the pusher is pressed, the pusher extends fully into the through hole. Rotating the rotating door plate closes the outer opening of the inlet hole, thereby securing the pusher between the near ends of the two locking rods.

[0066] The lifting frame 3 is mounted vertically on the translation frame 2. A support plate 33 is detachably connected between the lifting frames 3 on the two base plates 1. The support plate 33 is arc-shaped. The support plate 33 is used to support the large pipe 5. The curvature of the support plate 33 is adapted to the curvature of the pipe wall of the large pipe.

[0067] A perforation is formed in the upper part of the lifting frame 3. The locking beam 4 is adjusted to pass through the perforation. A tie is detachably connected between one end of the locking beam 4 on the two base plates 1.

[0068] In a preferred embodiment, the translation frame 2 includes two legs 25 and a lower connecting beam 26. The lower connecting beam 26 connects the upper ends of the two legs 25. The sliding plate 21 is connected to the lower end of the legs 25.

[0069] In this embodiment, the skateboard is elongated. The lower ends of the support legs are vertically mounted at one end of the skateboard. A diagonal brace connects the other end of the skateboard to the upper end of the support legs.

[0070] The outrigger 25 has vertically arranged socket holes inside. The lifting frame 3 includes two columns 31. The columns 31 are movably inserted into the socket holes. A rack is installed on the side wall of the column 31. A drive gear is rotatably mounted on the upper part of the outrigger 25. The drive gear meshes with the rack.

[0071] See Figure 6 As shown, the support leg is a hollow square tube. The upright is also a square tube. The outer diameter of the upright is adapted to the inner diameter of the support leg. The upright can move vertically within the cavity of the support leg.

[0072] A gearbox is mounted on the upper part of the outrigger. Perforations are formed in the tube walls of both the gearbox and the outrigger. The gear is rotatably mounted in the gearbox via an axle. One side of the gear rotatably passes through the perforation and meshes with the rack of the column.

[0073] In this embodiment, the gear axles of the support legs on the two base plates are coaxially connected together via a coupling. Construction workers can rotate one end of the coupling to simultaneously rotate the two gears in the same direction, driving the column to move up and down.

[0074] See Figure 7 A tilted height-maintaining rod 313 is rotatably connected to the gearbox. One end of the height-maintaining rod is rotatably connected to the top of the gearbox via a hinge shaft. The other end of the height-maintaining rod is detachably inserted between two adjacent teeth of the rack to prevent the column from descending.

[0075] Continue reading Figure 1 As shown, a central connecting beam connects the two columns 31. The two ends of the support plate 33 are detachably connected to the central connecting beam of the lifting frame 3 of the two base plates 1.

[0076] This invention provides a method for temporary pipe support of a large-scale temporary pipe fixing support device, comprising the following steps:

[0077] S1: The two base plates 1 are respectively placed on opposite sides of the foundation below the large pipe 5.

[0078] S2: Lower the anchoring member 11 of the two base plates 1 so that the anchoring member 11 is embedded in the foundation.

[0081] S5: Based on the elevation of the bottom of the large pipe 5, adjust the height of the support plate 33 of the lifting frame 3.

[0082] S6: Hoist the large pipe 5 and place it on the support plate 33.
