Supporting device for manufacturing reinforcing steel bars in cement pipeline

Abstract

The invention relates to the technical field of reinforcing steel bars, and discloses a supporting device for manufacturing reinforcing steel bars in a cement pipeline. The supporting device comprises a pipe, a support assembly and an air-entrapping assembly, the bottom end of the pipe is movably connected with a first telescopic rod, the left side of the first telescopic rod is fixedly provided with an air guide rod, and the inner wall of the air guide rod is fixedly provided with an air valve. When a rotating handle is rotated, an actuating rod can be driven to rotate, the actuating rod extrudes a second bent telescopic rod, so that gas in the second bent telescopic rod is extruded out and enters an outer box, and when the actuating rod rotates to the position of a thick rod of the second bent telescopic rod, a coil spring is bent, so that the actuating rod is bent, along with rotation of the rotating handle, after the actuating rod is separated from the thick rod position of the second bent telescopic rod, the actuating rod is straightened under the action of the coil spring, so that the other second bent telescopic rod is continuously extruded, gas enters an inner pipe along the outer box, the inflation process can be carried out in cooperation with pipes with different diameters, and internal supporting of the pipes is stabilized.

Description

technical field [0001] The invention relates to the technical field of steel bars, in particular to a support device for making steel bars inside cement pipes. Background technique [0002] Steel bars are the necessary materials in the process of building construction. Its existence makes the building more stable and safer. In the early days, buildings without steel bars as inner columns had poor safety and stability, and the buildings could not It has been preserved for a long time. In modern buildings, steel bars exist in various forms in the interior of the building, some as window frames, some as pillars, but most of them are used as bases, which are mainly used for high-rise buildings. support.

[0002] Steel bars are the necessary materials in the process of building construction. Its existence makes the building more stable and safer. In the early days, buildings without steel bars as inner columns had poor safety and stability, and the buildings could not It has been preserved for a long time. In modern buildings, steel bars exist in various forms in the interior of the building, some as window frames, some as pillars, but most of them are used as bases, which are mainly used for high-rise buildings. support

[0003] The application range of steel bars is very wide. In some pipelines, steel bars are also used. Pipes need to have a certain strength. Therefore, many pipelines now use steel bars to strengthen the strength of the pipeline. First, the steel bars are made into steel fine cages. After tying up the steel cage, pour cement into it and wait for the cement to dry before use. However, when the cement is half dry, the pipeline is relatively fragile at this time, and the steel bars are easy to leak out, and the pipeline has holes and leaks. happened, so we introduced a support device for making steel bars inside cement pipes to solve such problems
