Description

Technical Field

[0001] This utility model relates to the field of well electromechanical construction technology, and in particular to a retractable fixed bracket. Background Technology

[0002] When installing risers during the construction of electromechanical systems in pipe wells, it is necessary to build fixed supports. Since the wall dimensions on different floors cannot be guaranteed to be completely uniform during the construction of electromechanical systems in pipe wells, if traditional fixed supports are used, the dimensions of the pipe wells need to be measured layer by layer and then the fixed supports are processed by manual welding. Moreover, traditional fixed support processes have disadvantages such as not being able to be mass-produced by mechanization, low welding efficiency, limited applicability, easy to produce errors, high labor intensity for workers, and high construction costs.

[0003] Therefore, there is an urgent need to research and invent a retractable fixed support to solve the problems of traditional construction techniques, such as the ability to mass-produce similar fixed supports in wells, eliminate structural errors in wells, improve construction efficiency, and save construction costs. Utility Model Content

[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a retractable fixed support that can be mass-produced mechanically, eliminating errors in well structure, improving construction efficiency, and saving construction costs.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A retractable fixing bracket, including

[0007] The outrigger assembly includes a left fixed outrigger and a right fixed outrigger. Both the left fixed outrigger and the right fixed outrigger are provided with a fixed palm plate and a limiting part that is perpendicularly connected to the fixed palm plate. The fixed palm plate is provided with a mounting hole, and the limiting part is provided with a limiting groove. The bottom surface of the limiting groove is provided with a first elongated hole.

[0008] The crossarm has a second elongated oval hole on each side of its bottom surface. The second elongated oval hole is used to be installed and fixed with the first elongated oval hole by means of a bolt assembly. The side of the crossarm has a U-shaped code hole for installing the well riser.

[0009] According to an embodiment of this utility model, a retractable fixed bracket has at least the following beneficial effects: Before installation, the dimensions of individual floor manholes need to be measured and approximate data recorded, allowing for mass production of support leg components and crossbars. During on-site installation, the support leg components are installed first, ensuring the left and right fixed legs are installed at the same height. Then, both ends of the crossbar are placed into the limiting grooves of the left and right fixed legs, respectively. By using a vertical alignment method, the distance of the crossbar's left and right movement is adjusted to ensure the alignment of the U-shaped code holes reserved in the upper and lower brackets. Then, bolts are used to firmly fix the crossbar and support leg components through the first and second elongated oval holes, thus completing the installation of the entire retractable fixed bracket. The next bracket is then installed, and finally, the manhole riser is installed on the corresponding U-shaped code hole of each bracket. For manhole structures with different error ranges, the error in the manhole structure can be eliminated by adjusting the reserved length of the second elongated oval hole of the crossbar and the first elongated oval hole of the support leg component. This retractable fixed bracket enables automated mass production in machinery factories, reducing the workload of welding workers, improving construction safety, and significantly increasing the efficiency of automated production compared to manual welding, thus achieving certain socio-economic benefits.

[0039] Reference below Figures 1-4 A retractable fixing bracket is described in detail with reference to a specific embodiment. It is to be understood that the following description is merely illustrative and not intended to limit the scope of the invention.

[0040] like Figures 1-4 As shown, a retractable fixed bracket includes a leg assembly and a crossbeam 170.

[0041] The outrigger assembly includes a left fixed outrigger 100 and a right fixed outrigger 110. Both the left and right fixed outriggers are equipped with a fixed foot plate 120 and a limiting part 130 perpendicularly connected to the fixed foot plate 120. The fixed foot plate 120 has mounting holes 140, and the limiting part 130 has a limiting groove 150. The bottom surface of the limiting groove 150 has a first elongated hole 160. The crossbeam 170 has second elongated holes 180 on both sides of its bottom surface. The second elongated holes 180 are used to engage with the first elongated holes 160 for installation and fixation via bolt assemblies. The side of the crossbeam 170 has U-shaped bracket holes 190 for installing manhole risers. Before installation, the dimensions of individual manholes on different floors need to be measured and approximate data recorded. This allows for mass production of the outrigger assembly and crossbeams. During on-site installation, the outrigger assembly is installed first. Figure 2 As shown, the left fixed support leg 100 and the right fixed support leg 110 must be installed at the same height. Then, place both ends of the crossarm 170 into the limiting grooves 150 of the left fixed support leg 100 and the right fixed support leg 110 respectively. By using a vertical line laying method, adjust the left and right movement distance of the crossarm 170 to ensure that the U-shaped code holes 190 reserved on the upper and lower supports are aligned. Then, use bolt assemblies to firmly fix the crossarm 170 to the support leg assembly through the first elongated hole 160 and the second elongated hole 180. Figure 1 As shown, the installation of the entire telescopic fixed bracket is completed, then the next bracket is installed, and finally the well riser is installed on the corresponding U-shaped code hole 190 of each bracket. For well structures with different error ranges, the error of the well structure can be eliminated by adjusting the reserved length of the second elongated hole 180 of the crossarm 170 and the first elongated hole 160 of the outrigger assembly. This telescopic fixed bracket can realize the automated mass production of the bracket in the machine shop, reduce the intensity of welding work for workers, improve construction safety, and the automated production efficiency is also much higher than that of manual welding, realizing a certain degree of social and economic benefits.

[0042] Specifically, if Figure 3As shown, the limiting part 130 includes side limiting plates 200 arranged parallel to each other on the left and right, and a limiting base plate 210 connecting the two side limiting plates 200. A limiting groove 150 is formed between the two side limiting plates 200 and the limiting base plate 210, and a first elongated hole 160 is provided in the limiting base plate 210. This arrangement of the limiting part 130 facilitates its forming, and the formed limiting groove 150 effectively limits the crossarm 170. The first elongated hole 160 in the limiting base plate 210 facilitates its engagement with the second elongated hole 180. Furthermore, the fixing plate 120, the side limiting plates 200, and the limiting base plate 210 are all made of carbon structural steel plates. Carbon structural steel plates have high strength and are mainly used in railways, bridges, and various building projects to manufacture various metal components that bear static loads. Further, the fixing plate 120, the side limiting plates 200, and the limiting base plate 210 are connected by welding. Welding is a high-efficiency and reliable connection method. It should be noted that the mounting holes 140 are located at the four corners of the fixed palm plate 120. The presence of mounting holes 140 at all four corners ensures that the fixed palm plate 120 is securely installed.

[0043] like Figure 4 As shown, the crossarm 170 includes an upper horizontal plate 220 and a lower horizontal plate 230 arranged parallel to each other, and a side horizontal plate 240 connecting the upper horizontal plate 220 and the lower horizontal plate 230. A second circular hole is provided on the lower horizontal plate 230, and U-shaped code holes 190 are provided on the side horizontal plate 240. The crossarm 170 is structurally stable due to the arrangement of the upper horizontal plate 220, the lower horizontal plate 230, and the side horizontal plate 240. The second circular hole on the lower horizontal plate 230 facilitates the installation of the spiral assembly, and the U-shaped code holes 190 on the side horizontal plate 240 facilitate the installation of the well riser. Specifically, multiple U-shaped code holes 190 are spaced apart along the side horizontal plate 240. This arrangement of U-shaped code holes 190 allows for the spaced installation of multiple well risers. It should be noted that the multiple U-shaped code holes 190 are set at the same height. Setting the U-shaped code holes 190 at the same height is beneficial for processing and for the installation of the well riser. It is worth mentioning that the crossarm 170 is made of carbon structural channel steel. The crossarm 170 uses carbon structural channel steel, which has high strength and stable structure.

[0044] Understandably, the bolt assembly includes a screw, nut, and flush insert (the bolt assembly itself is not shown in the figure). The bolt assembly, with its screw, nut, and flush insert, is easy to install and provides a secure connection.
