Description

Technical Field

[0001] The utility model relates to the technical field of large-scale pipeline construction, in particular to a large-scale pipeline bracket capable of adjusting the lifting and lowering. Background Art

[0002] At present, in the construction application of urban drainage pipe installation, when the drainage pipe is installed to the position of the cast-in-place reinforced concrete drainage well chamber, in order to allow the concrete pipe to be smoothly connected to the drainage well chamber, it is necessary to reserve half of the pipe body to be suspended in the well chamber foundation pit, so as to facilitate the subsequent installation of the well chamber's steel bars and formwork.

[0003] In order to prevent the half-suspended concrete pipe from falling off, workers usually add bricks at the bottom of the concrete pipe to stabilize the concrete pipe and prevent it from falling off. However, due to the heavy weight of large pipes, the diameter of large pipes is generally greater than or equal to 1500mm. When bricks are added to the bottom of the pipe, the bricks are easily crushed by the pipe. When bricks are added to the bottom, because multiple bricks are stacked, the brick structure is unstable and easy to loosen, increasing the risk of the pipe falling off, and the safety of workers installing the pipe at the bottom is threatened.

[0004] When installing the pipeline, its installation elevation needs to be strictly controlled. In the concrete pipe connected to the drainage well chamber, the traditional method uses slowly adding different types of bricks to increase or lower the pipe, thereby adjusting the elevation. This method of adjusting the elevation is slow to construct, has a large elevation error, and multiple adjustments can easily cause the stacked bricks to loosen, increasing the risk of the pipe falling. Utility Model Content

[0038] This embodiment provides a large pipe bracket that can be adjusted to rise and fall. Figure 1-Figure 3, including a lifting mechanism, a steel plate platform 6, a supporting structure and a pallet 2 arranged in sequence from bottom to top, the middle part of the top surface of the pallet 2 is an arc-shaped structure, the arc-shaped structure can be adapted to support the arc-shaped bottom surface of the concrete pipe 1, so that the concrete pipe 1 can always be stably supported in the middle part of the top surface of the pallet 2, forming left and right side limits to ensure the stability of the support; the steel plate platform 6, the supporting structure and the pallet 2 are an integral structure, and the lifting mechanism can adjust the height of the steel plate platform 6, the supporting structure and the pallet 2 as a whole. And by adjusting the height of the steel plate platform 6, the supporting structure and the pallet 2 as a whole through the lifting mechanism, the elevation of the concrete pipe 1 can be adjusted, and the adjustment efficiency is high and the adjustment is stable. When installing the concrete pipe 1 of the drainage well chamber, the risk of the concrete pipe 1 falling can be reduced.

[0039] like Figure 1-Figure 3 As shown, the lifting mechanism includes a hydraulic jack 7, which has a simple structure and strong power, and can better control the elevation of the concrete pipe 1. The number of hydraulic jacks 7 can be selected according to demand. As a preferred embodiment, the lifting mechanism includes four hydraulic jacks 7, which are distributed in a rectangular array under the steel plate platform 6, and the support is stable. The top heights of the four hydraulic jacks 7 can form a plane, so that the elevation of the concrete pipe 1 can be adjusted in multiple directions.

[0040] The support structure includes a main support 4, an auxiliary support 3 and a scissor support 5;

[0041] like Figure 1 and Figure 2 As shown, the main support 4 is symmetrically arranged on both sides of the arc direction of the support plate 2, that is, the main support 4 is symmetrically arranged on the left and right sides, which can evenly support the lateral sides of the concrete pipe 1; the main support 4 is arranged vertically, and the upper end of the main support 4 is connected to the bottom of the support plate 2, and the lower end is connected to the top of the steel plate platform 6;

[0042] The scissors brace 5 is connected between the main supports 4 on both sides, and the ends of the scissors brace 5 are connected to the connection between the main support 4 and the support plate 2 and the connection between the main support 4 and the steel plate platform 6; the scissors brace 5 is connected between the main supports 4 on both sides to form a whole as the main supporting structure, and the supporting stability is higher;

[0043] The auxiliary support 3 is obliquely arranged at the outer sides of the main support 4 on both sides, and the lower end of the auxiliary support 3 is connected to the connection between the main support 4 and the steel plate platform 6, and the upper end is connected to the bottom of the support plate 2.

[0044] The lower end of the scissors support 5, the lower end of the main support 4 and the lower end of the auxiliary support 3 converge on the steel plate platform 6, with stronger supporting capacity; the upper end of the scissors support 5 and the upper end of the main support 4 converge at the bottom of the support plate 2, with stronger supporting capacity; the upper end of the auxiliary support 3 is connected to both sides of the bottom of the support plate 2 to form a cantilever support, so that the stability of the support plate 2 supporting the concrete pipe 1 is better.

[0045] In this embodiment, Figure 3 As shown, the main supports 4 are also symmetrically arranged in the axial direction of the support plate 2, that is, the main supports 4 are also provided with four, and two main supports 4 adjacent to each other on both sides of the arc direction of the support plate 2 are connected as a whole by scissor braces. And as a preferred embodiment, as Figure 2 and Figure 3 As shown, the main support 4 and the hydraulic jack 7 are arranged at corresponding positions, and the support stability is better.

[0046] In this embodiment, the support plate 2 is an arc-shaped steel plate. As an implementation method, the diameter of the arc-shaped steel plate is greater than or equal to 2800 mm, which can make the diameter of the arc-shaped steel plate greater than the diameter of most concrete pipes 1, thereby enabling the arc-shaped steel plate to be used for more stable support of concrete pipes 1 with diameters less than 2800 mm, and its adaptability is stronger. The central angle corresponding to the curvature of the arc-shaped steel plate is greater than or equal to 80°, and the central angle corresponding to the curvature of the arc-shaped steel plate is less than or equal to 130°. For example, the central angle corresponding to the curvature of the arc-shaped steel plate is 120°, which ensures that the concrete pipe 1 will not roll down and ensures the stability of the support.

[0047] In this embodiment, the axial length of the arc-shaped steel plate is 400-600 mm, and the thickness is 4 mm-6 mm. For example, the axial length of the arc-shaped steel plate is 400 mm, and the thickness of the arc-shaped steel plate is 5 mm. The structure is light and convenient for transportation and conversion. The end face of one axial end of the arc-shaped steel plate is 15-25 cm away from the corresponding end face of the concrete pipe 1. Figure 3 As shown, the arc-shaped steel plate can provide a stable supporting point for the concrete pipe 1 and can stably hold the concrete pipe 1 .

[0048] like Figure 2 As shown, as an embodiment, the ratio of the diameter of the support plate 2 to the diameter of the concrete pipe 1 is 1.1-1.3, and a gap is provided between the two sides, which is convenient for construction operation and can adapt to concrete pipes 1 of different diameters. The central angle corresponding to the curvature of the support plate 2 is greater than or equal to 80°, and the central angle corresponding to the curvature of the support plate 2 is less than or equal to 130°, so that when the concrete pipe 1 is located in the support plate 2, the stability of the concrete pipe 1 is ensured.

[0049] In this embodiment, a plurality of supporting steel blocks are further included. After the elevation of the concrete pipe 1 is adjusted by the lifting mechanism, the steel plate platform 6 is supported by the supporting steel blocks instead of the lifting mechanism, and the lifting mechanism can be taken out for reuse.

[0050] In this embodiment, a well chamber concrete bottom plate 8 is also included, and the lifting mechanism is supported on the well chamber concrete bottom plate 8 to provide sufficient strength support for the lifting mechanism.

[0051] The adjustable lifting large pipe bracket of this embodiment is flexible and simple, and includes the following steps:

[0052] Step 1. Prepare materials: a 5mm thick, 500mm long arc-shaped steel plate as a support plate 2 to stabilize the pipeline; 4 Φ48mm, 500mm long diagonal bracing steel pipes as auxiliary supports 3 to make the support more stable; 4 Φ48mm, 300mm long steel pipes as main supports 4 to bear and transfer the weight of the concrete pipe above; 2 scissor braces consisting of 4 Φ48mm, 450mm long, as the main supporting structure to make the overall structure more stable; a 5mm thick, 500mm long, 400mm wide steel plate platform as the bottom balancing surface to provide a welding surface for the steel pipe; 4 10-ton hydraulic jacks, which are retractable, as the adjustment structure of the entire bracket.

[0053] Step 2: Place the curved steel plate with a thickness of 5mm and a length of 500mm horizontally, and weld a Φ48mm, 300mm long supporting steel pipe, a 5mm thick, 500mm long, 400mm wide steel plate platform, a Φ48mm, 500mm long diagonal bracing steel pipe, and a Φ48mm, 450mm long scissor brace at the bottom of the curved steel plate. Use a welding machine to weld them into a whole to form a bracket.

[0054] Step 3. When using, first place the bracket at the position 9 of the well chamber foundation pit, add 4 hydraulic jacks to the 4 main supporting steel pipe positions at the bottom, and use the hydraulic jacks to adjust the elevation when installing the concrete pipe. If the elevation of the concrete pipe is too low, extend the jack; if the elevation of the concrete pipe is too high, retract the jack. After the elevation of the concrete pipe is adjusted, carry out the concrete well chamber construction as soon as possible, use supporting steel blocks instead of hydraulic jacks for support, then release the jack hydraulic valve and retract the jack. When the well chamber concrete construction is completed and meets the strength requirements, pull out the supporting steel blocks at the bottom of the bracket from the side and recycle the bracket. By adjusting the bracket with the hydraulic jack, an efficient and safe method of installing large pipelines at the well chamber location is formed.

[0055] This embodiment is aimed at the problem that "during the installation of large concrete pipes in the inspection well chamber, bricks are added to the bottom of the pipe to achieve the design effect of the pipe installation. When bricks are added to the bottom of the pipe in the traditional method, the bricks are easily loosened, and the weight of the pipe is easy to crush the bricks, which causes the pipe to become unstable and fall off, posing a huge safety threat to the pipeline construction personnel. The bricks used in the construction to adjust the elevation of the pipe are not accurate, and it is difficult to meet the design requirements." This embodiment studies and provides a large pipe bracket with adjustable lifting, which effectively solves the safety technical problem that during the installation of large pipes in the well chamber, the bricks are easily loosened, and the weight of the concrete pipe is easy to crush the bricks, causing the concrete pipe to become unstable and fall off. And solves the construction technical problem that the bricks used to adjust the elevation of the concrete pipe are not accurate, and it is difficult to meet the design requirements. And the large pipe bracket with adjustable lifting has simple material selection, convenient assembly, flexible use, and can be recycled many times, saving the labor cost when installing the pipe, reducing safety risks, and greatly improving the construction efficiency of pipe installation.

[0056] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
